Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.
Increased levels of PROLACTIN in the BLOOD, which may be associated with AMENORRHEA and GALACTORRHEA. Relatively common etiologies include PROLACTINOMA, medication effect, KIDNEY FAILURE, granulomatous diseases of the PITUITARY GLAND, and disorders which interfere with the hypothalamic inhibition of prolactin release. Ectopic (non-pituitary) production of prolactin may also occur. (From Joynt, Clinical Neurology, 1992, Ch36, pp77-8)
A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.
Multiple Endocrine Neoplasia Type 1
A form of multiple endocrine neoplasia that is characterized by the combined occurrence of tumors in the PARATHYROID GLANDS, the PITUITARY GLAND, and the PANCREATIC ISLETS. The resulting clinical signs include HYPERPARATHYROIDISM; HYPERCALCEMIA; HYPERPROLACTINEMIA; CUSHING DISEASE; GASTRINOMA; and ZOLLINGER-ELLISON SYNDROME. This disease is due to loss-of-function of the MEN1 gene, a tumor suppressor gene (GENES, TUMOR SUPPRESSOR) on CHROMOSOME 11 (Locus: 11q13).
Growth Hormone-Secreting Pituitary Adenoma
A condition caused by prolonged exposure to excessive HUMAN GROWTH HORMONE in adults. It is characterized by bony enlargement of the FACE; lower jaw (PROGNATHISM); hands; FEET; HEAD; and THORAX. The most common etiology is a GROWTH HORMONE-SECRETING PITUITARY ADENOMA. (From Joynt, Clinical Neurology, 1992, Ch36, pp79-80)
Encyclopedias as Topic
The behavior of performing an act persistently and repetitively without it leading to reward or pleasure. The act is usually a small, circumscribed behavior, almost ritualistic, yet not pathologically disturbing. Examples of compulsive behavior include twirling of hair, checking something constantly, not wanting pennies in change, straightening tilted pictures, etc.
An enzyme that catalyzes the desaturation (aromatization) of the ring A of C19 androgens and converts them to C18 estrogens. In this process, the 19-methyl is removed. This enzyme is membrane-bound, located in the endoplasmic reticulum of estrogen-producing cells of ovaries, placenta, testes, adipose, and brain tissues. Aromatase is encoded by the CYP19 gene, and functions in complex with NADPH-FERRIHEMOPROTEIN REDUCTASE in the cytochrome P-450 system.
Trans-sphenoidal surgery for microprolactinoma: an acceptable alternative to dopamine agonists? (1/259)AIMS: Reported cure rates following trans-sphenoidal surgery for microprolactinoma are variable and recurrence rates in some series are high. We wished to examine the cure rate of trans-sphenoidal surgery for microprolactinoma, and to assess the long-term complications and recurrence rate. DESIGN: A retrospective review of the outcome of trans-sphenoidal surgery for microprolactinoma, performed by a single neurosurgeon at a tertiary referral centre between 1976 and 1997. PATIENTS: All thirty-two patients operated on for microprolactinoma were female, with a mean age of 31 years (range 16-49). Indications for surgery were intolerance of dopamine agonists in ten (31%), resistance in six (19%) and resistance and intolerance in four (12.5%). Two patients were from countries where dopamine agonists were unavailable. RESULTS: The mean pre-operative prolactin level was 2933 mU/l (range 1125-6000). All but 1 had amenorrhoea or oligomenorrhoea, with galactorrhoea in 15 (46.9%). Twenty-five (78%) were cured by trans-sphenoidal surgery, as judged by a post-operative serum prolactin in the normal range. During a mean follow-up of 70 months (range 2 months to 16 years) there was one recurrence at 12 years. Post-operatively, one patient became LH deficient, two patients became cortisol deficient and two became TSH deficient. Out of 21 patients tested for post-operative growth hormone deficiency, 6 (28.6%) were deficient. Five patients developed post-operative diabetes insipidus which persisted for greater than 6 months. There were no other complications of surgery. The estimated cost of uncomplicated trans-sphenoidal surgery, and follow-up over 10 years, was similar to that of dopamine agonist therapy. CONCLUSION: In patients with hyperprolactinaemia due to a pituitary microprolactinoma, transsphenoidal surgery by an experienced pituitary surgeon should be considered as a potentially curative procedure. The cost of treatment over a 10 year period is similar in uncomplicated cases to long-term dopamine agonist therapy. (+info)
Increased episodic release and disorderliness of prolactin secretion in both micro- and macroprolactinomas. (2/259)To quantify prolactin (PRL) secretion patterns, ten untreated (female) microprolactinoma patients and six (male) macroprolactinoma patients underwent repetitive blood sampling every 10 min over 24 h. PRL release activity was analyzed from plasma PRL concentration (immunofluorimetric assay) profiles via a model-independent discrete peak detection program (Cluster) and a waveform-independent deconvolution technique (Pulse). Diurnal variations were analyzed by cosinor analysis. The number of distinct PRL pulses (mean +/- S.E.M.) was increased in patients: microprolactinoma 18.6 +/- 0.6/24 h versus female controls 12.4 +/- 0.6 (P = 6.7 x 10-s), and macroprolactinoma 18.0 +/- 0.9 versus male controls 13.5 +/- 0.8/24 h (P = 0.003). In patients, PRL pulse height, amplitude, pulse area and interpeak nadir concentrations were each greatly elevated compared with gender-matched controls. By 2-component deconvolution analysis, the mean nadir PRL secretion rate in microprolactinoma patients was augmented 20-fold at 0.408 +/- 0.089 microgram/l per min versus in female controls 0.019 +/- 0.009 microgram/l per min (P < 0.001); and in macroprolactinoma by 130-fold at 2.067 +/- 0.693 micrograms/l per min versus male controls 0.016 +/- 0.001 microgram/l per min (P = 0.001). Corresponding 24 h mean PRL secretion rates were in women, 0.658 +/- 0.147 and 0.044 +/- 0.018 (P < 0.001), and in men, 3.309 +/- 1.156 and 0.035 +/- 0.010 micrograms/l per min (P = 0.001), being respectively 15- and 94-fold increased in tumors. The estimated PRL production per day was 160 +/- 15 and 187 +/- 20 micrograms in male and female controls respectively. PRL production was 2860 +/- 640 micrograms in female patients with microadenomas (P < 0.001), and 37,800 +/- 5900 micrograms in male macroadenoma patients (P = 0.001). Cosinor analysis of the plasma concentrations revealed a significant rhythm in nine of ten, patients with a microadenoma, and in five of six with a macroadenoma. The same method applied to pulse height and amplitude disclosed a significant rhythm for PRL pulse height, but not for pulse amplitude, suggesting preserved rhythmicity of baseline interpulse nadir PRL concentrations. Approximate entropy (ApEn), a scale- and model-independent regularity statistic, averaged 1.6559 +/- 0.028 in microprolactinoma patients versus 0.8128 +/- 0.079 in female controls (P = 1.7 x 10(-8)); ApEn in macroadenomas was 1.5674 +/- 0.054 versus male controls 0.8773 +/- 0.076 (P = 1.7 x 10(-5), signifying greater secretory irregularity in the patients. Compared with microadenomas, macroadenomas exhibited a higher mean plasma concentration, overall mean PRL secretion rate, nadir secretion rate and pulse area, but similar peak frequency. We conclude that PRL secretion by prolactinomas is characterized by increased plasma PRL episodicity of release, increased total (15- to 100-fold) and basal (20- to 130-fold) secretion rates, and increased disorderlines of minute-to-minute secretion. These abnormalities of secretory control are very similar to those for GH and ACTH identified earlier in acromegaly and Cushing's disease respectively, thus suggesting mechanistic generality of pituitary tumor secretory derangements, independent of the particular hormone.

Pituitary tumours in the elderly: a 20 year experience. (3/259)The proportion of the elderly in the population is increasing, and the appreciation and management of medical problems in this age group will therefore become more important. We therefore decided to determine the clinical features and types of pituitary tumour presenting in the elderly, and to examine the treatment and outcome in this group. We conducted a retrospective case-note review from a specialist endocrine and neurosurgical unit in a tertiary referral centre. Eighty-four patients aged 65 years and over on diagnosis of a pituitary tumour were referred to the unit between 1975 and 1996. There were 45 males and 39 females, and the mean age was 72.4 years (range 65-86). Over half of the pituitary lesions were non-functioning adenomas (NFAs) (60.7%). GH-secreting tumours were present in 11 (13.1%) and macroprolactinomas in 7 (8.1%). Four patients had microadenomas and 17 had miscellaneous pituitary-related lesions. Visual deterioration was the commonest mode of presentation in 33 (39.3%), but 54 (64.3%) had evidence of visual impairment on detailed examination. Despite the majority of patients (80.8%) having coexisting medical conditions, trans-sphenoidal surgery was performed in 60 (71.4%) and was well tolerated with a zero peri- and post-operative mortality rate, and post-operative complications in 11 (13.1%). Pituitary tumours in the elderly are most frequently NFAs that present with visual deterioration and hypopituitarism. The fact that 46.5% were pan-hypopituitary on diagnosis and that 64.3% of patients had visual impairment suggests a delay in diagnosis in this age group. Despite significant coexisting medical pathology in this large series of patients, surgery was safe and successful in the majority. (+info)
Mitogen-activated protein kinase activation by stimulation with thyrotropin-releasing hormone in rat pituitary GH3 cells. (4/259)We examined whether mitogen-activated protein (MAP) kinase is activated by thyrotropin-releasing hormone (TRH) in GH3 cells, and whether MAP kinase activation is involved in secretion of prolactin from these cells. Protein kinase inhibitors--such as PD098059, calphostin C, and genistein--and removal of extracellular Ca2+ inhibited MAP kinase activation by TRH. A cAMP analogue activated MAP kinase in these cells. Effects of cAMP on MAP kinase activation were inhibited by PD098059. TRH-induced prolactin secretion was not inhibited by levels of PD098059 sufficient to i activation but was inhibited by wortmannin (1 microM) and KN93. Treatment of GH3 cells with either TRH or cAMP significantly inhibited DNA synthesis and induced morphological changes. The effects stimulated by TRH were reversed by PD098059 treatment, but the same effects stimulated by cAMP were not. Treatment of GH3 cells with TRH for 48 h significantly increased the prolactin content in GH3 cells and decreased growth hormone content. The increase in prolactin was completely abolished by PD098059, but the decrease in growth hormone was not. These results suggest that TRH-induced MAP kinase activation is involved in prolactin synthesis and differentiation of GH3 cells, but not in prolactin secretion. (+info)
A novel germline mutation of multiple endocrine neoplasia type 1 (MEN1) gene in a Japanese MEN1 patient and her daughter. (5/259)Familial multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant inherited disorder characterized by tumors of the parathyroid, anterior pituitary and gastro-entero-pancreatic endocrine tissues. The MEN1 gene has recently been cloned and its germline mutations have been considered to play an important role in the tumorigenesis of MEN1. We analyzed a Japanese MEN1 patient and her daughter for germline mutations of the MEN1 gene. The proband (60 y.o.) had primary hyperparathyroidism (PHP) and gastrinoma, and her daughter (30 y.o.) had prolactinoma. Clinical examinations revealed no evidence of PHP in the daughter. We identified a novel heterozygous germline mutation (712 A del) at codon 201 in exon 3 of the MEN1 gene in the proband. Restriction digestion analysis revealed the same mutation pattern in her daughter. These findings suggest that this family has familial MEN1 including a rare case of MEN1 with a single lesion of the pituitary. Genetic examinations are useful as diagnostic tools for any rare or variant case of familial MEN1. (+info)
Giant insulinoma in a patient with multiple endocrine neoplasia-type I: a case report. (6/259)We report a case of giant cystic insulinoma constituting part of multiple endocrine neoplasia (MEN) type I. A 29-year-old Japanese man presented with a history of recurrent hypoglycemic attacks. Endocrine examination showed hyperinsulinemia discordant with hypoglycemia, and a giant cystic insulinoma (11 x 10 cm) located in the pancreatic tail was detected radiologically. Hyperprolactinemia due to pituitary adenoma and hyperparathyroidism due to parathyroid hyperplasia were also present. The insulinoma, prolactinoma and hyperplastic parathyroid gland were surgically removed. Fluorescent microsatellite analysis detected loss of heterozygosity (LOH) in chromosome 11q13 in DNA samples from all resected tissues but not from white blood cells. This is a rare case of MEN type I because of the giant cystic insulinoma and the evidence of common LOH detected in all MEN type I tissues. (+info)
Galactorrhoea and pituitary mass: a typical prolactinoma? (7/259)A 21 year old woman presenting with galactorrhoea, hyperprolactinaemia, and a pituitary mass on magnetic resonance imaging (MRI) is described who was referred to us before planned pituitary surgery. Although a thorough history did not suggest hypothyroidism, laboratory studies revealed profound primary hypothyroidism. At that time, pituitary MRI showed homogeneous enlargement of the pituitary gland consistent with pituitary hyperplasia due to primary hypothyroidism. With thyroid hormone replacement therapy the galactorrhoea resolved, concentrations of prolactin and thyroid hormones returned to normal, and the pituitary shrunk to normal size within two months. This case illustrates that primary hypothyroidism can present only with galactorrhoea and pituitary mass, and should therefore be considered in the differential diagnosis of hyperprolactinaemia and pituitary enlargement.

Proliferation, bcl-2 expression and angiogenesis in pituitary adenomas: relationship to tumour behaviour. (8/259)The prediction of pituitary tumour behaviour, in terms of response to treatment from which can be derived optimal management strategies, is a challenge that has been approached using several different means. Angiogenesis in other tumour types has been shown to be correlated with poor response to treatment and tumour recurrence. The aim of this paper is to assess the role of measurements of cell proliferation and angiogenesis in predicting pituitary tumour behaviour. The proliferative capacity of the tumour was assessed using the Ki-67 labelling index (LI) while bcl-2 expression was used to assess anti-apoptotic pathways. The microvessel density (MVD) was assessed using antibodies to CD31 and factor VIII-related antigen, and with biotinylated ulex europaeus agglutinin I. There was no difference between Ki-67 LI and MVD of functionless tumours that recurred and those that did not, but bcl-2 expression was significantly lower in tumours that subsequently regrew. Macroprolactinomas had significantly higher LI than microprolactinomas and than all other tumours. Cell proliferation and angiogenesis were not related, showing that both processes are under different control mechanisms in pituitary tumours. In contrast there was a positive relationship between markers of angiogenesis and bcl-2 expression in prolactinomas, GH-secreting tumours and non-recurrent functionless tumours with higher levels of bcl-2 expression being found in the more vascular tumours. These findings may suggest that angiogenesis is related to the ability of tumour cells to survive rather than their proliferative activity. (+info)

Prolactinoma is the most prevalent anterior hypophysis tumor. The principal treatment for this disorder is Dopamine agonist drugs including bromocriptin and Cabergoline. However, 50% of Bromocriptin treated and 17% of Cabergoline treated patients are resistant to these drugs. Curcumin is the main derivative of turmeric ,an old spice which is used frequently in Indian and Iranian cuisine. It has been proved that curcumin can reduce mammotrope cells proliferation and also intracellular hormone production. The purpose of this study is to evaluate the effect of turmeric on prolactinoma patients ...
ASUHAN KEPERAWATAN: Prolactinoma - Causes, Symptoms & Treatments
Infertility and changes in menstruation cycle are two common symptoms of this problem. Due to prolactinoma, the menstrual periods of women may stop completely or they occur irregularly. Women who are neither pregnant nor nursing a baby may start producing milk as a result of prolactinoma. Dryness in vagina may also occur and this makes intercourse a painful experience. Many women also lose interest in sexual activities due to prolactinoma. For treating this disease, medication is generally given to the patients. Surgical treatment may also be done for those patients who are not benefited by medication. If medication is not successful or mildly successful then radiation therapy and surgery may also be required. The treatment of prolactinoma aims at reducing the size of tumor while bringing the leve of prolactin to normal in the body ...
Prolactinoma - Wikipedia
If a woman has one or more small prolactinoma, there is no reason that she cannot conceive and have a normal pregnancy after successful medical therapy. The pituitary enlarges and prolactin production increases during normal pregnancy in women without pituitary disorders. Women with prolactin-secreting tumors may experience further pituitary enlargement and must be closely monitored during pregnancy. However, damage to the pituitary or eye nerves occurs in less than one percent of pregnant women with prolactinoma. In women with large tumors, the risk of damage to the pituitary or eye nerves is greater, and some doctors consider it as high as 25%. If a woman has completed a successful pregnancy, the chances of her completing further successful pregnancies are extremely high. A woman with a prolactinoma should discuss her plans to conceive with her physician, so she can be carefully evaluated prior to becoming pregnant. This evaluation will include a magnetic resonance imaging ...
Valvular heart disease and the use of cabergoline for the treatment of prolactinoma. - Physiology, Anatomy and Genetics
OBJECTIVE: The use of high doses of the ergot-derived dopamine agonist cabergoline (| 3 mg/day), especially with cumulative doses | 4000 mg, has been associated with an increase in cardiac valvular thickening and significant (moderate to severe) regurgitation. Whether lower doses commonly used in the treatment of prolactinomas (0.25-3 mg/week) are also associated with significant valvulopathy is controversial. The mitral valve tenting area, a subclinical index of leaflet stiffening, has also been correlated with the cumulative dose of cabergoline and severity of valvular regurgitation. DESIGN/PATIENTS/MEASUREMENTS: We performed transthoracic echocardiography (TTE) on 50 prolactinoma patients (48% macroprolactinomas, 52% microprolactinomas, 30 male, 20 female, age 51.2 +/- 2.2 years, mean +/- SEM) who had been taking cabergoline for 6.6 +/- 0.5 years (range 1-13 years) with cumulative doses of 443 +/- 53 mg, to determine the prevalence of significant valvular thickening (| 0.5 cm) and regurgitation, and

Association of prolactin receptor (PRLR) variants with prolactinomas. - Radcliffe Department of Medicine
Prolactinomas are the most frequent type of pituitary tumors, which represent 10-20% of all intracranial neoplasms in humans. Prolactinomas develop in mice lacking the prolactin receptor (PRLR), which is a member of the cytokine receptor superfamily that signals via Janus kinase-2-signal transducer and activator of transcription-5 (JAK2-STAT5) or phosphoinositide 3-kinase-Akt (PI3K-Akt) pathways to mediate changes in transcription, differentiation and proliferation. To elucidate the role of the PRLR gene in human prolactinomas, we determined the PRLR sequence in 50 DNA samples (35 leucocytes, 15 tumors) from 46 prolactinoma patients (59% males, 41% females). This identified six germline PRLR variants, which comprised four rare variants (Gly57Ser, Glu376Gln, Arg453Trp and Asn492Ile) and two low-frequency variants (Ile76Val, Ile146Leu), but no somatic variants. The rare variants, Glu376Gln and Asn492Ile, which were in complete linkage disequilibrium, and are located in the PRLR intracellular domain,

Prolactinomas have harmful effects on human health, and the pathogenesis is still unknown. Furthermore, 25% of prolactinoma patients do not respond to the therapy of dopamine receptor agonist in the clinic. Thus, it is important to reveal the pathogenesis and develop new therapeutic methods for prolactinomas. Herein, two animal models of prolactinomas, namely oestrogen-treated rats and transgenic D2 dopamine receptor-deficient mice, were used. PET/CT imaging detection showed that translocator protein-mediated microglia activation and inflammation significantly increased in the pituitary glands of prolactinomas rats. Messenger RNA microarrays were used to analyze and compare the differential gene and signal pathways of the pituitary glands between control and prolactinomas rats. Statistical results pertaining to gene enrichment showed that the innate immune response genes were upregulated in the pituitary glands of prolactinoma rats. This suggested that the innate immune response was activated. ...

A 56-year-old man was brought to the Emergency Department after being found collapsed at his office with a reduced level of consciousness. From clinical examination and initial investigations, he was diagnosed as having bacterial meningitis and was promptly commenced on empirical i.v. antibiotics. Computed tomography of the brain revealed a parenchymal mass at the base of the skull and subsequent magnetic resonance imaging of the head 4 days later confirmed a large soft tissue mass, which extended through to the cavernous sinus. Examination of the cerebrospinal fluid (CSF) following lumbar puncture confirmed pneumococcal meningitis and antibiotics were continued for 2 weeks in total. During the admission, hormone profiling revealed a grossly elevated prolactin. When coupled with the initial results of the brain imaging, this result helped to confirm a macroprolactinoma that was invading the postnasal space. A final diagnosis of pneumococcal meningitis secondary to invading prolactinoma was made. ...
DICER1 mutation and pituitary prolactinoma - Radcliffe Department of Medicine
A young woman carrying germline DICER1 mutation was discovered to have a pituitary microprolactinoma when she became amenorrhoic. The mutation was identified as a result of family screening following the early death of the patients daughter with ovarian cancer. The patient was in follow-up screening for thyroid disease, and investigations were initiated when she became amenorrhoic. MR scan revealed a 6 mm diameter pituitary microadenoma and raised prolactin. The prolactin was efficiently suppressed with low-dose cabergoline, and her menstrual cycles resumed. Dicer is an RNase enzyme, which is essential for processing small non-coding RNAs. These molecules play pleiotropic roles in regulating gene expression, by targeting mRNA sequences for degradation. DICER1 plays different roles depending on cell context, but is thought to be a functional tumour suppressor gene. Accordingly, germline mutation in one DICER1 allele is insufficient for oncogenesis, and a second hit on the other allele is required, as a

Co-secretion of growth hormone (GH) and prolactin (PRL) from a single pituitary adenoma is common. In fact, up to 25% of patients with acromegaly may have PRL co-secretion. The prevalence of acromegaly among patients with a newly diagnosed prolactinoma is unknown. Given the possibility of mixed GH and PRL co-secretion, the current recommendation is to obtain an insulin-like growth factor-1 (IGF-1) in patients with prolactinoma at the initial diagnosis. Long-term follow-up of IGF-1 is not routinely done. Here, we report two cases of well-controlled prolactinoma on dopamine agonists with the development of acromegaly 10-20 years after the initial diagnoses. In both patients, a mixed PRL/GH-cosecreting adenoma was confirmed on the pathology examination after transsphenoidal surgery (TSS). Therefore, periodic routine measurements of IGF-1 should be considered regardless of the duration and biochemical control of prolactinoma. ...

IJMS | Free Full-Text | Relation among Aromatase P450 and Tumoral Growth in Human Prolactinomas
The pituitary gland is part of hypothalamic-pituitary-gonadal axis, which controls development, reproduction, and aging in humans and animals. In addition, the pituitary gland is regulated mainly by hormones and neurotransmitters released from the hypothalamus and by systemic hormones secreted by target glands. Aromatase P450, the enzyme responsible for the catabolization of aromatizable androgens to estrogens, is expressed in different parts of body, including the pituitary gland. Moreover, aromatase P450 is involved in sexual dimorphism where alteration in the level of aromatase can initiate a number of diseases in both genders. On the other hand, the direct actions of estrogens, mainly estradiol, are well known for stimulating prolactin release. Numerous studies have shown that changes in the levels of estrogens, among other factors, have been implicated in the genesis and development of prolactinoma. The pituitary gland can produce estradiol locally in several types of endocrine cells, and it is
Pituitary disease: presentation, diagnosis, and management | Journal of Neurology, Neurosurgery & Psychiatry
The vast majority of microprolactinomas and macroprolactinomas respond to ergot derived dopamine receptor agonists such as cabergoline or bromocriptine. For many patients cabergoline has a more satisfactory side effect profile than bromocriptine, and at doses used for pituitary disease, psychoses and clinically significant fibrotic reactions are rare. Microprolactinomas change little in size with treatment but macroprolactinomas can be expected to shrink, sometimes quite dramatically. Although not teratogenic, dopamine receptor agonists are withdrawn as soon as pregnancy is confirmed and visual fields checked at intervals to identify the small proportion of women whose macroprolactinomas enlarge significantly.. It is important that the objectives of microprolactinoma treatment are kept in mind. In a patient with galactorrhoea, reducing prolactin concentrations with dopamine analogues is clearly central, but for women in whom the problem of hyperprolactinaemia relates only to suppressed oestrogen ...
The Hormone Connection: The pituitary gland
The most common disorders of the pituitary gland are adenomas. Adenomas are benign tumors that secrete in excess one or more of the pituitary hormones and are not subject to the normal feedback controls of the body. The most common one is called prolactinoma. A prolactinoma secretes prolactin in excess. It usually presents with breast milk discharge in a woman that is not pregnant. In a man, it may present with breast enlargement. This benign tumors can grow to cause pressure in the optic nerve that crosses above the pituitary gland. When that happens the person may experience blindness in peripheral vision. Prolactinomas are one of the few tumors that can be shrunk with medication and does not need surgery ...

Prolactina (en sangre)
Es un análisis para medir el nivel de prolactina que tiene en la sangre. La prolactina es una hormona producida por la glándula pituitaria, que se encuentra en el cerebro. En las mujeres embarazadas, la prolactina estimula las mamas para que produzcan leche materna. Si las células que producen prolactina en la glándula pituitaria comienzan crecer fuera de control, pueden formar tumores denominados prolactinomas. Los prolactinomas, también conocidos como adenomas lactótropos, no suelen ser cancerosos. En la mayoría de los casos, se producen en las mujeres menores de 50 años. Un síntoma del prolactinoma es la producción de leche materna aunque no esté embarazada. En los hombres, los prolactinomas pueden causar problemas para alcanzar o mantener una erección (impotencia) o disminución del deseo sexual. Si le diagnostican un prolactinoma, es posible que su proveedor de atención médica le dé un medicamento denominado agonista de la dopamina, como la bromocriptina o la cabergolina. La ...

TY - JOUR. T1 - Age-related changes in prolactin secretion and the population of mammotrophs in the rat. T2 - A longitudinal study. AU - Ooka, H.. AU - Shinkai, T.. PY - 1992. Y1 - 1992. N2 - The concentration of prolactin (PRL) in the blood increases with aging in the rat, and pituitary prolactinomas often develop in aged female rats. We measured blood PRL levels in the course of development of hyperprolactinemia and prolactinomas in individual rats by serial sampling of the blood of living rats. The pituitaries were examined upon the death of the rats to detect prolactinomas by immunocytochemical staining. Hyperprolactinemia in rats without pituitary tumors was inevitably followed by the development of a prolactinoma within 3 months. Rats which had no tumors at the time of death had low PRL levels throughout their lifespan. Counting of anterior pituitary cells after immunocytochemical staining for electron microscopy indicated that the number of mammotrophs increased and that the number of ...

Nausea and vomiting, nasal stuffiness, headache, and drowsiness are common side effects of these medications. However, these side effects often can be minimized if your doctor starts you with a very low dose of medication and gradually increases the dose.. Cabergoline is the preferred treatment because it appears to be more effective than bromocriptine. It also has less frequent and less severe side effects. However, its more expensive than bromocriptine and its newer, so its long-term safety record isnt as well-established.. There have been rare cases of heart valve damage with cabergoline, but usually in people taking much higher doses for Parkinsons disease. Some people may also develop compulsive behaviors, such as gambling, while taking these medications.. If medication shrinks the tumor significantly and your prolactin level remains normal for two years, you may be able to taper off the medication with your doctors guidance. However, recurrence is common. Dont stop taking your ...

Pituitary tumors are the most common form of intracranial neoplasms. Their prevalence in autopsy series was reported as 5-20 %.1 However, clinically relevant pituitary tumors presenting with disturbances of hormonal secretion or mass effect are rare, with an estimated prevalence of 200/1,000,000 and an incidence of 2/100,000 per year.2 Therefore, they only represent about 10 % of all surgically resected intracranial neoplasms.3,4

Other hormones overproduced may be growth hormone (in adult, it causes big hands, feet and head, night sweats and in children, excessive height) and ACTH (It may cause weight gain, moon face and hypertension). 2) Under-secretion of hormones (excessive tiredness and excessive urine, especially at night). 3) Blurred vision due to compression of the eye nerves (optic nerve and chiasma) (patients may bump into things when walking past a door because of poor periphery vision) and occasionally double vision. 4) Headache. Assessment often includes assessment of hormonal status (by an endocrinologist) and vision (by an ophthalmologist).. If the tumour secretes prolactin (prolactinoma), often surgery is not needed. Treatment with drugs, bromocryptine or carbagoline, is often sufficient.. If the tumour is not a prolactinoma, surgery is often needed. It is often done through the nose (transphenoidal). ...

Angiogenesis in pituitary adenomas - relationship to endocrine function, treatment and outcome. - Oxford Neuroscience
Angiogenesis has been shown to be related to tumour behaviour, prognosis and response to treatment in many different tumour types. The aim of this study was to examine the relationship between angiogenesis and tumour behaviour and response to treatment in pituitary adenomas. The microvessel density (MVD) of pituitary tumours was assessed by counting blood vessels labelled with 3 different endothelial markers using antibodies to CD31, factor eight-related antigen and biotinylated Ulex europaeus (agglutinin I UEAI). One hundred and forty-two surgically removed pituitary adenomas (46 GH secreting, 6 microprolactinomas, 19 macroprolactinomas, 18 ACTH secreting and 53 functionless tumours) were carefully characterized and assessed. There was a significant negative correlation between age and MVD of GH secreting tumours (R(2)=33.8, P=0.005). Age was not related to MVD in other tumour types. Pre-treatment hormone production by the adenomas was related to MVD in prolactinomas (P|0.05), but not in GH secreting

Pituitary tumor... - Nerve conditions - Condition | Our Health
Hi. Ill try to keep this as short as I can. In Oct 2002, I had a pituitary tumor removed via craniotomy. (It wasnt in a position where they could go through the nose) My symptoms were few. Lost all menstruation, elevated prolactin levels. I had gained a lot of weight. Anyway, the pathology reports of this tumor came back inconclusive. They were not able to determine exactly what kind of tumor it was. They said if I was done having children, it wasnt necessary to go on meds to get my period back. Four years later, I still dont have my periods, still overweight. No other symptoms. I am done having children, but worry I may never get back to my normal self. I can go on meds to get my period back, but Ive heard the side effects are often unbearable. Nausea, dizziness, and its ongoing. Is it dangerous for me to continue this way? I mean, is it possible I could develop more problems if I dont have a period for so long? They said it was okay, but I worry.Thank You,SusanHiLooked up prolactinoma ...

Pituitary carcinomas are very rare neoplasms with a poor prognosis. We report a case of Cushings disease resulting from a pituitary carcinoma in a ZZ-yr-old female, who died of massive hepatic failure. At autopsy, there was invasion of the parasellar structures and vasculature by the tumor, which stained positively only for ACTH. There were two metastatic nodules in the liver, which also stained positively for ACTH. When compared to other cases of Cushings disease (n = 52), other pituitary adenomas (n = 292), and normal pituitary tissues (n = 21), the pituitary carcinoma was the only one with c-erbB-2 membrane staining in both the sellar-located tissue and liver metastasis. C-erbB-2 staining was present in the cytoplasm of a variable number of cells in 40% of the invasive adenomas (n = 103), while only 1.2% of the noninvasive tumors (n = 241) expressed this protein (p , 0.001). No particular immunohistological type preferentially expressed this protein. in normal pituitary tissues, 10% of the ...

The goals of this study are: to verify whether cabergoline and pasireotide are effective in NFPA to control tumor re-growth as adjuvant therapy after neurosurgery and whether pasireotide is capable of normalizing the prolactin levels in patients with prolactinomas resistant to cabergoline; to assess the mRNA levels of dopamine receptor type 2 (DR2) and SSTR1-5 and their protein expression; to evaluate the in vitro hormonal response to cabergoline, octreotide and pasireotide; and to determine whether the mRNA DR2/SSTR1-5 and/or protein expression and/or in vitro hormonal response to cabergoline, octreotide and pasireotide correlates with the in vivo response to the former and to the last one. With this data the investigators intend to establish if the mRNA analysis and/or protein expression in NFPA and resistant prolactinomas might be predictive or foretelling factors concerning drug treatment in patients with this kind of pituitary tumors and also evaluate if there is any response in vitro or in ...

Often times, the examination was conducted to find the cause of hyperprolactinemia. Causes The most common are prolactinomas, which is a prolactin-producing pituitary tumors can be divided according to their size into makroadenoma (, 1 cm) or microadenomas (,1 cm.). Prolactinomas were diagnosed through pencitraaan pituitary gland using magnetic resonance imaging (MRI) or computed tomography (CT). The main concern is the growth of tumors in pregnancy is more common in makroprolaktinoma. Prolactin secretion is inhibited by dopamine, so that dopamine agonists (eg, bromocriptine) is used to treat hyperprolactinemia. Hyperprolactinemia causes amenorrhea and dopamine agonists are used to restore fertility. Once pregnant, most women can discontinue the treatment. However, in case makroadenoma, dopamine agonist therapy is ...
Lactotropic cell - Wikipedia
A lactotropic cell (also known as prolactin cell, epsilon acidophil, lactotrope, lactotroph, mammatroph, mammotroph) is a cell in the anterior pituitary which produces prolactin in response to hormonal signals including dopamine which is inhibitory and thyrotropin-releasing hormone which is stimulatory. Other regulators include oxytocin, estrogen and progesterone. Prolactin is involved in the maturation of mammary glands and their secretion of milk in association with oxytocin, estrogen, progesterone, glucocorticoids, and others. Prolactin has numerous other effects in both sexes. Prolactin cells are acidophilic by hematoxylin & eosin stains and comprise about 20% of all cells in the anterior pituitary gland. If these cells undergo neoplastic transformation, they will give rise to a prolactinoma, a prolactin-secreting pituitary adenoma. ...
The Masculine Heart: Prolactin - The Brain Chemical That Can Kill Libido in Long-Term Relationships
Nice article. I am a 29 yo male. I can confirm the whole lot. Several years ago, I was diagnosed with Sarcoidosis and was put on a large course of Cortisone for around a year. After that, my energy levels and libido disappeared.. After visiting the emergency ward six months ago, due to persistent migraines, I was diagnosed with a large Prolactinoma. I was put on a course of medication to shrink the Prolactinoma and thus reduce the total level of prolactin in the blood. The normal level of prolactin is between 250-500, mine was at 6000. When I was diagnosed with the tumour, the doc asked Feeling tired, sexual problems, weight gain and low libido?. They were right on the money. Well it is now six months on from being diagnosed, and I can happily say I have the libido of a teenager (funnily inconvenient to me and my beautiful fiancé), energy levels are returning and weight is coming off (prolactin count is now 800, so whatever the docs are doing is definitely working ...

TY - JOUR. T1 - Either isoform of the dopamine D2 receptor can mediate dopaminergic repression of the rat prolactin promoter. AU - McChesney, Ruth. AU - Sealfon, Stuart C.. AU - Tsutsumi, Manami. AU - Dong, Ke Wen. AU - Roberts, James L.. AU - Bancroft, Carter. PY - 1991/8. Y1 - 1991/8. N2 - Hypophyseal portal dopamine is a major negative regulator of pituitary prolactin (PRL) production. Dopamine has been reported to repress PRL gene transcription in pituitary cells. To facilitate further study of the effect of dopamine on PRL gene activation, we introduced PRL promoter and D2 receptor (D2R) constructs into GH3 cells. Since two D2R isoforms (termed D2S and D2L) have been cloned previously, we first determined which isoform(s) is present in the lactotroph by measuring the level of each mRNA species in rat prolactinoma. mRNA for each D2R isoform was found to be present, with the D2L mRNA in great (c. 6-fold) excess. Because the lactotroph contains both isoforms, the effect of each on the PRL ...

Pituitary imaging in mild hyperprolactinaemia | SFEBES2019
Background: Hyperprolactinaemia is a common presentation in endocrine clinics. Current guidelines on BMJ best practice recommend evaluation with MRI only if levels are >2000 mU/l or absence of an identifiable secondary cause.. Aim: To identify if pituitary pathology would go undetected if pituitary imaging is not performed and determine a suitable threshold for performing pituitary imaging in the diagnosis of prolactinoma.. Methods: A retrospective study on 100 new patients with raised prolactin level below 1000 mU/l (17 75 years old) over 12 months (Jan Dec 2017).. Result: 33 male and 67 female studied. 16% of patients had prolactin level of 350 500 mU/l, 54% with prolactin level of 500 700 mU/l and 30% between 750 1000 mU/l. Menstrual irregularities were the most common symptoms (22%) followed by Erectile dysfunction/Gynaecomastia (16%), headache (10%). Fatigue 8%, subfertility 6% and galactorrhoea 5%. 33% were asymptomatic. MRI pituitary was performed on 60 patients and CT head on 2. MRI ...
Most recent papers with the keyword Pituitary | Read by QxMD
We have previously reported a critical role of HMGA proteins in pituitary tumorigenesis since either the Hmga1 or Hmga2 gene overexpression/activation induces the development of mixed growth hormone/prolactin cell pituitary adenomas by activating the E2F transcription factor 1, and then enhancing the G1/S transition of the cell cycle. Consistently, amplification and overexpression of the HMGA2 gene was found in human pituitary prolactinomas. Since impairment of the cell cycle control represents a feature of experimental and human pituitary adenomas, we have investigated the possible synergism between the alterations of other cell cycle regulators, such as p27 deficiency or Cdk4(R24C) mutation, with Hmga2 overexpression in pituitary tumorigenesis ...

An intelligent decision support tool for early diagnosis of functional pituitary adenomas
In this work, a web based integrated Medical Decision Support System (MDSS) tool for mainly early diagnosis of functional pituitary adenomas (i.e., somatotrophinoma, corticotrophinoma and prolactinoma) is developed. In the MDSS tool, hormone diseases are described by means of well-classified set of attributes generated from the typical sign and symptoms of disorders.The proposed tool is based on a stationary linear stochastic system model which specifically predicts the selected hormone diseases employing certain system parameters. The MDSS tool is user friendly which includes questions and answers at the opening session of the self-test. Questions and answers session will be completed by yes or no type of simple-responses. Based on our clinical results, MDSS tool yields more than 99% correct decisions on the selected hormone diseases. It is expected that effective use of the proposed MDSS tool will save substantial amount of valuable time of an expert endocrinologists and minimizes the cost ...

Adverse drug reaction suggests by a clinical vignette Albert J FinestoneTemple University School of Medicine, Philadelphia, PA, USAI had a three-lobe pneumonia and toxic encephalopathy in 2004. A lumbar puncture did not show meningitis. Magnetic resonance imaging showed a macroadenoma of the pituitary gland. Prolactin level was significantly elevated, making the diagnosis a functioning prolactinoma requiring treatment. Initially, I was treated with the dopamineagonist cabergoline, which is also used in much larger doses to treat Parkinsonism. Recent reports have indicated heart valve damage in Parkinsonism patients treated with ergot-derived dopamine-receptor agonists.
From a Tiara to a Tumor: Miss Nevadas Struggle with a Pituitary Adenoma - Pituitary World News
From our friend Christina Bourne ONeil -. I was diagnosed with a prolactinoma in 2005. Prior to my diagnosis and before my symptoms began I had very few health problems. When my symptoms initially began, I assumed they were typical problems that every young woman experienced. I had headaches, fatigue and irregular menses. However, when I began having severe heart palpitations I knew I needed to see a doctor. I was referred to a cardiologist and was put on a beta-blocker to stop the palpitations.. In 2003 I was crowned Miss Nevada and had the honor of competing for the title of Miss America 2004. During my year as Miss Nevada, my symptoms became worse. I began having trouble maintaining my body temperature, my periods became irregular and unpredictable, and I was becoming more and more fatigued. I was told that it was likely because of the stress that I was under. I was prescribed a higher dosage of birth control to regulate my menses and did my best to reduce stress.. In 2005, I suddenly began ...
