A novel skeletal dysplasia with developmental delay and acanthosis nigricans is caused by a Lys650Met mutation in the fibroblast growth factor receptor 3 gene. (1/88)

We have identified a novel fibroblast growth factor receptor 3 (FGFR3) missense mutation in four unrelated individuals with skeletal dysplasia that approaches the severity observed in thanatophoric dysplasia type I (TD1). However, three of the four individuals developed extensive areas of acanthosis nigricans beginning in early childhood, suffer from severe neurological impairments, and have survived past infancy without prolonged life-support measures. The FGFR3 mutation (A1949T: Lys650Met) occurs at the nucleotide adjacent to the TD type II (TD2) mutation (A1948G: Lys650Glu) and results in a different amino acid substitution at a highly conserved codon in the kinase domain activation loop. Transient transfection studies with FGFR3 mutant constructs show that the Lys650Met mutation causes a dramatic increase in constitutive receptor kinase activity, approximately three times greater than that observed with the Lys650Glu mutation. We refer to the phenotype caused by the Lys650Met mutation as "severe achondroplasia with developmental delay and acanthosis nigricans" (SADDAN) because it differs significantly from the phenotypes of other known FGFR3 mutations.  (+info)

A quantitative scale of acanthosis nigricans. (3/88)

OBJECTIVE: To develop and validate a scale for acanthosis nigricans (AN). RESEARCH DESIGN AND METHODS: Subjects were participants from the San Antonio Family Diabetes Study and the San Antonio Family Heart Study. A total of 406 subjects were independently examined for AN by at least two observers. Five locations were examined: the neck, axilla, elbows, knuckles, and knees. Interobserver concordance and kappa statistics were calculated to determine replicability of the scale. Comparisons of diabetes-related risk factors by AN score were also calculated. RESULTS: Only the neck had consistently high kappa statistics, and thus, other locations were excluded from further analyses. Elevated AN was strongly associated with elevated fasting insulin and BMI in both diabetic and nondiabetic subjects. Elevated AN was also strongly associated with elevated fasting glucose, systolic blood pressure, and diastolic blood pressure, and with decreased HDL in nondiabetic subjects. In diabetic subjects, elevated AN was associated with elevated total cholesterol. CONCLUSIONS: We have developed a scale for AN that is easy to use, has high interobserver reliability in Mexican Americans, and correlates well with fasting insulin and BMI. This scale will permit longitudinal and cross-sectional evaluation of AN and will permit the evaluation of AN as a trait in genetic studies.  (+info)

Highly activated Fgfr3 with the K644M mutation causes prolonged survival in severe dwarf mice. (4/88)

Several gain-of-function mutations in a receptor tyrosine kinase, fibroblast growth factor receptor 3 (FGFR3), cause dwarfism in humans. Two particularly severe dwarfisms, thanatophoric dysplasia type II (TDII) and severe achondroplasia with developmental delay and acanthosis nigricans (SADDAN), are associated with glutamic acid (E) and methionine (M) substitutions at the K650 residue in the kinase domain. TDII is lethal at birth, whereas most of the SADDAN patients survive the perinatal period. However, FGFR3 with the SADDAN mutation is more activated than FGFR3 with the TDII mutation in vitro. To find out whether the K650M mutation also causes the SADDAN phenotype, we introduced the corresponding point mutation (K644M) into the mouse Fgfr3 gene. Heterozygous mutant mice show a phenotype similar to human SADDAN, e.g. the majority of the SADDAN mice survive the perinatal period. This suggests that the survival of SADDAN patients is indeed attributed to the K650M mutation in FGFR3. The long bone abnormalities in SADDAN mice are milder than the TDII model. In addition, overgrowth of the cartilaginous tissues is observed in the rib cartilage, trachea and nasal septum. The FGF ligand at the low concentration differentially activates Map kinase in primary chondrocyte cultures from wild-type and SADDAN mice. Comparisons of the molecular bases of the phenotypic differences in SADDAN and TDII mice may increase our understanding of the factors that influence the severity in these two related skeletal dysplasias.  (+info)

HAIR-AN syndrome: a multisystem challenge. (5/88)

HAIR-AN syndrome is an acronym for an unusual multisystem disorder in women that consists of hyperandrogenism (HA), insulin resistance (IR) and acanthosis nigricans (AN). The precipitating abnormality is thought to be insulin resistance, with a secondary increase in insulin levels and subsequent overproduction of androgens in the ovaries. Long periods of hyperinsulinism and, some suspect, hyperandrogenism can result in the cutaneous manifestation of acanthosis nigricans. Patients are often concerned about the physical manifestations of this disorder, including virilization and acanthosis nigricans, and may be less aware of systemic problems. Physicians should assess women with these problems for an underlying endocrine abnormality. Although a treatment regimen for the HAIR-AN syndrome has not been established, antiandrogen therapy and weight loss are useful.  (+info)

Association of acanthosis nigricans with race and metabolic disturbances in obese women. (6/88)

Acanthosis nigricans (AN) has been recognized as a marker of insulin resistance and diabetes mellitus. We have compared frequency of race and metabolic disturbances in obese women with several degrees of AN (AN group, N = 190) to a group without AN (non-AN group, N = 61) from a mixed racial population. The groups were similar regarding age and body mass index. All patients (except the diabetic patients) underwent an oral glucose tolerance test (75 g). The racial distribution of this population was 35.1% white, 37.8% mulatto and 27.1% black and the frequency of AN was 62.5, 82.1 and 83.8%, respectively, higher in black versus white (P = 0.003) and mulatto versus white (P = 0.002) women. The frequencies of diabetes mellitus and impaired glucose tolerance were 5.8 and 12.6% in the AN group and 1.6 and 8.2% in the non-AN group, respectively (P>0.05). Fasting glucose, beta cell function determined by the homeostasis model of assessment (HOMA), fasting insulin and insulin area under the curve were similar for the AN and non-AN groups. A higher HOMA insulin resistance was observed in the AN group compared to the non-AN group (P = 0.02) and in the subgroup of highest degree of AN compared to those with other degrees. The mean lipid levels and the frequency of dyslipidemia were similar for the two groups. AN was strongly associated with the black or mulatto rather than the white race, even after taking into account the effect of age, body mass index and HOMA insulin resistance.  (+info)

Gamma-linolenic acid in borage oil reverses epidermal hyperproliferation in guinea pigs. (7/88)

As dietary sources of gamma-linolenic acid [GLA; 18:3(n-6)], borage oil (BO; 24-25 g/100 g GLA) and evening primrose oil (PO; 8-10 g/100 g GLA) are efficacious in treating skin disorders. The triglycerol stereospecificity of these oils is distinct, with GLA being concentrated in the sn-2 position of BO and in the sn-3 position of PO. To determine whether the absolute level and/or the triglycerol stereospecificity of GLA in oils affect biological efficacy, epidermal hyperproliferation was induced in guinea pigs by a hydrogenated coconut oil (HCO) diet for 8 wk. Subsequently, guinea pigs were fed diets of PO, BO or a mixture of BO and safflower oil (SO) for 2 wk. The mixture of BO and SO (BS) diet had a similar level of GLA as PO but with sn-2 stereospecificity. As controls, two groups were fed SO and HCO for 10 wk. Epidermal hyperproliferation was reversed by all three oils in the order of BO > BS > PO. However, proliferation scores of group PO were higher than of the normal control group, SO. The accumulations of dihomo-gamma-linolenic acid [DGLA; 20:3(n-6)], an elongase product of GLA, into phospholipids and ceramides, of 15-hydroxyeicosatrienoic acid (15-HETrE), the potent antiproliferative metabolite of DGLA, and of ceramides, the major lipid maintaining epidermal barrier, in the epidermis of group BO were greater than of groups BS and PO. Group BS had higher levels of DGLA, 15-HETrE and ceramides than group PO. With primary dependence on absolute levels, our data demonstrate that the antiproliferative efficacy of GLA in the epidermis is preferably exerted from sn-2 stereospecificity of GLA in BO.  (+info)

We found acanthosis nigricans to be associated with having multiple risk factors for type 2 diabetes mellitus in patients aged 7 to 39 years. As the number of these risk factors increased, so did the prevalence of acanthosis nigricans in both children and adults. The positive likelihood ratio of having this dermatologic condition in patients with more than 2 risk factors for type 2 diabetes was 8.3 for ages 7 to 19 years and 4.2 for ages 20 to 39 years.. Most studies have found acanthosis nigricans to be associated with insulin resistance or hyperinsulinemia, major factors in the pathophysiology of type 2 diabetes, in a substantial proportion of patients.8,9,11-14,22,23 Although our study did not measure insulin levels, we found that acanthosis nigricans was independently associated with diagnosed type 2 diabetes. Patients with this dermatologic condition were 1.97 times more likely to have type 2 diabetes compared with their counterparts without it, after controlling for age, BMI, and the ...
In young persons, acanthosis nigricans is a visible marker which strongly suggests insulin resistance. Higher than normal insulin levels in the blood stream cause the growth of darkened skin over certain areas of the body. No skin treatment will get rid of AN. Acanthosis nigricans may lighten up and possibly go away by treating the root cause, insulin resistance, but it can take months or years to do so.[9] Insulin resistance syndromes may be divided into type A (HAIR-AN) and type B syndromes.[2]:978 The majority of cases of acanthosis nigricans are associated with obesity and otherwise idiopathic. This is likely because of insulin resistance, and more likely to occur in darker-skinned persons.[2]:968 This can also be referred to as pseudoacanthosis nigricans. ...

Objective. To determine the prevalence of acanthosis nigricans (AN) and other diabetes risk factors in urban school health clinics. Methods. During the period 2006-2009 nurse practitioners (NPs) screened students who had a BMI ≥ 95th percentile and 1 additional diabetes risk factor. Blood glucose (BG) was measured by finger stick. NPs were trained on how to ascertain the presence of AN on the neck area. Results. NPs screened 854 students (mean age 11.4 years, 60.5% female, and 73.3% black). AN and elevated BG were found among 26% and 6.4% of students, respectively. Females and minorities were respectively 50% and 4 times more likely to have AN. Youth with AN were twice as likely to have elevated glucose. Conclusion. AN can be easily identified by trained health care professionals even in busy school-based clinic settings. Checking for AN and appropriate education and counseling should become a routine part of electronic documentation in overweight youth ...
Some patients with mutations of the FGFR3 gene will develop the SADDAN syndrome - severe achondroplasia, developmental delay and acanthosis nigricans.
Background and aim: Acanthosis nigricans (AN) is characterized by hyperpigmented velvety plaques of body folds and neck. Insulin can have a role in the pathogenesis of this disease and hyperinsulinemia as a consequence of insulin resistance may stimulate the formation of the characteristic plaques of AN. In this study insulin resistance was compared in obese women with and without AN.Materials and Methods: Glucose tolerance test (GTT) and fasting blood insulin were measured in two groups of obese women (BMI|30 kg/m2) with AN (32 cases) and without AN (34 cases) and insulin resistance was determined using HOMA formula.Results: The mean fasting blood insulin in two groups with and without AN were 15.5±8.5 and 12.2±4.1 IU/mL; respectively (P|0.05). The mean of insulin resistance in two groups with and without AN were 3.5±1.9 and 2.6±0.9; respectively (P|0.05). The results of GTT showed that the mean fasting blood sugar was 89.5±12 mg/dl and following using glucose were 144±7 mg/dl after 30 minutes,
Acanthosis Nigricans,a skin disorder of the neck,axilla and over the joints of the fingers and toes,Causes,Symptoms,Diagnosis and management
Acanthosis nigricans (AN) is a skin disorder in which there is darker, thick, velvety skin in body folds and creases. This condition usually appears slowly and doesnt cause any symptoms other than skin changes. Eventually, dark, velvety skin with very visible markings and creases appears in the armpits, groin and neck folds, and over the joints of the fingers and toes. Less commonly, the lips, palms, soles of the feet, or other areas may be affected. The exact cause of this condition is not well understood; but it can be inherited or related to medical problems such as obesity, diabetes mellitus (insulin- resistance), some prescription drugs, and cancer ...
If the condition is primary, the darkening of skin cannot be healed, but the condition may be manageable. The dog may receive steroids and melatonin injections. Special shampoos to reduce the production of seborrhea may also be recommended. For the secondary acanthosis nigricans there are several treatment options. The detection of the underlying condition causing the darkening of the skin must be detected and treated. An obese dog should follow a strict diet to lose some weight. Hormonal problems may also be treated with thyroid medication or surgery in more extreme cases. Allergies may not be treated but they may be controlled with steroid medication or antihistamines. Immunotherapy is also available if the irritant agent is discovered. The supplementation of vitamin E may also be helpful to improve the condition of the skin. Omega 3 fatty acids may also be recommended for a healthier skin. ...

Crouzonodermoskeletal syndrome is a disorder characterized by the premature joining of certain bones of the skull (craniosynostosis) during development and a skin condition called acanthosis nigricans. Some of the signs and symptoms of Crouzonodermoskeletal syndrome are similar to those seen with Crouzon syndrome. They include prematurely fused skull bones, which affect the shape of the head and face; wide-set, bulging eyes due to shallow eye sockets; eyes that do not point in the same direction (strabismus); a small, beaked nose; and an underdeveloped upper jaw. People with these conditions are generally of normal intelligence. Several features distinguish Crouzonodermoskeletal syndrome from Crouzon syndrome. People with Crouzonodermoskeletal syndrome have acanthosis nigricans, a skin condition characterized by thick, dark, velvety skin in body folds and creases, including the neck and underarms. In addition, subtle changes may be seen in the bones of the spine (vertebrae). Noncancerous growths ...
As far as I am concerned AN is the cutaneous manifestation of hyperinsulinism or insulin resistance. For starters I would get a very good family history for type 2 diabetes, PCOS, hirsutism, infertility, irregular menses, and obesity. You described her very politely as chunky but what is her BMI? The way I would document her degree of insulin resistance/carbohydrate tolerance is by doing a 2 hr oral glucose tolerance test with samples at 0, 30, 60, 90 and 120 minutes for BOTH insulin and glucose. At the 0 sample, since she will be fasting, I would also get cholesterol, LDLdirect, triglycerides and HDL(many of these children have the dyslipidemia associated with metabolic syndrome which is elevated TG and low HDL). The best treatment for insulin resistance, but the most difficult to achieve, is a healthier lifestyle, lots of fresh fruits and veggies, healthy oils, fat free milk, no fast food, no soda or other sugar sweetened beverages and juice limited to 4-6 oz/day. We also recommend limiting ...
The epidermal growth factor (EGF) is an important mediator of keratinocyte growth in vitro, and both the EGF receptor (EGF-R) and EGF are found in excessive amounts in the hyperproliferative epidermis. EGF needs to interact with insulin-like growth factor/somatomedin (IGF-1) or with high doses of insulin for keratinocyte proliferation. The IGF-I receptor is located in the basal layer of the epidermis, suggesting participation of IGF-1 and EGF in the regulation of epidermal growth and in the pathogenesis of hyperproliferative skin diseases.23 The prevalence of AN in unselected populations varies from 7 to 74%, according to age, race, frequency of type, degree of obesity and concomitant endocrinopathy. 24,25 In a study involving 34 obese individuals of both sexes in a predominantly black population (59%), Hud et al. reported prevalence of AN in 74% of the patients and demonstrated clear predominance of AN in dark-skinned and black women in relation to white women. 19 Stoddart et al.

A 28-year-old male presented with 2 days of vomiting and abdominal pain, preceded by 2 weeks of thirst, polyuria and polydipsia. He had recently started risperidone for obsessive-compulsive disorder. He reported a high dietary sugar intake and had a strong family history of type 2 diabetes mellitus (T2DM). On admission, he was tachycardic, tachypnoeic and drowsy with a Glasgow Coma Scale (GCS) of 10/15. We noted axillary acanthosis nigricans and obesity (BMI 33.2 kg/m2). Dipstick urinalysis showed ketonuria and glycosuria. Blood results were consistent with diabetic ketoacidosis (DKA), with hyperosmolar state. We initiated our DKA protocol, with intravenous insulin, fluids and potassium, and we discontinued risperidone. His obesity, family history of T2DM, acanthosis nigricans and hyperosmolar state prompted consideration of T2DM presenting with ketosis-prone diabetes (KPD) rather than T1DM. Antibody markers of beta-cell autoimmunity were subsequently negative. Four weeks later, he had ...

It is estimated that about one-third of people with diabetes will have a skin disorder at some time in their lives caused by the disease. Diabetics are more susceptible to bacterial and fungal infections; allergic reactions to medications, insect bites or foods; dry itchy skin as a result of poor blood circulation; and infections from foot injuries for people with neuropathy.. There are a number of diabetes-specific skin conditions:. Acanthosis Nigricans. A slowly progressing skin condition, which turns some areas of skin, usually in the folds or creases, into dark, thick and velvet-textured skin. Acanthosis nigricans often precedes the diagnosis of diabetes. It is sometimes inherited, but is usually triggered by high insulin levels. It can occur at any age and usually strikes people who are obese. There is no treatment for the condition except to reduce insulin levels. Prescription creams may help lighten the affected area.. Diabetic Blisters. Rare blisters that appear on the hands, toes, feet ...
The exact cause is not known, but acanthosis nigricans is often seen in association with endocrine disorders such as insulin resistance and PCOS.

American cocker spaniels are undoubtedly the most common breed presenting with primary idiopathic seborrhea and the most studied. Much of this work was reviewed by Kwochka.(Kwochka 1993) The defect in these dogs is a genetic programmed abnormality in epidermal proliferation. Affected cockers have shortened epidermal transit times and increased DNA synthesis in the basal cells. By doing epidermal-grafting studies Kwochka has shown the defect is epidermal and not related to serum or dermal factors. Clinical lesions most commonly seen are keratinous plaques that may occur on an erythematous base. The surface is a thick golden brown scale/crust. It is not uncommon to find subcorneal pustules in some areas along the margin of the plaques. In those instances the plaques will be crusty. The pustules indicate the presence of secondary pyoderma. Scaly lesions, comedones and follicular casts are usually prominent around the nipples, on the ventral surface of the tail, medial thighs, the perineal region, ...

N2 - Background: Defects of the insulin receptor gene (INSR) cause wide spectra of congenital insulin resistance. Monoallelic defects result in milder insulin-resistant diabetes mellitus with acanthosis nigricans (IRAN, type A). Whereas, leprechaunism (Donahue syndrome), the most severe condition with lethality during the infantile period is caused by biallelic defects of INSR. Materials and Methods: We detected 2 missense mutations in 2 cases of leprechaunism and IRAN, type A, and reduced mRNA expression in the leprechaunism case. We performed an in vitro analysis to confirm that the 2 missense mutations are ...
The type B insulin-resistance syndrome is characterized by the presence of anti-insulin receptor antibodies that cause severe insulin resistance [1, 2]. A 44-year-old, nonobese woman with Hashimoto thyroiditis and the Sjogren syndrome demonstrated severe insulin resistance and acanthosis nigricans. Plasma glucose and insulin levels during oral glucose tolerance testing were 7.3 to 22.1 mmol/L and 4264 to 10 986 pmol/L, respectively. Anti-insulin receptor antibodies were detected in serum, but results of tests for anti-insulin antibody were negative. When oral prednisolone was administered at a starting dose of 40 mg, severe hyperglycemia immediately developed. Because massive insulin ...
We have described both a new form of lipodystrophy and a new phenotype of T2DM. Patients with T2DM and PLL are distinguished by 1) the presence of T2DM or prediabetes, 2) symmetrical lipodystrophy of the forearms, or forearms plus calves, or less commonly, whole limbs, and 3) acanthosis nigricans. Metabolically, these patients have profound insulin resistance, with little or no measurable insulin-mediated glucose disposal during hyperinsulinemic clamps. When compared with the control T2DM patients, the PLL patients will often have greater elevations of hepatic transaminases, suggesting more pronounced hepatic steatosis and more marked hypertriglyceridemia, and report the onset of T2DM a full decade earlier (at ∼29 years). T2DM with PLL can affect patients identifying with multiple ethnic and racial groups and appears to most commonly occur in women.. The pattern of fat loss is dissimilar from that reported for known forms of lipodystrophy with any consistency, and T2DM with PLL does not ...
Confluent and reticulated papillomatosis is a rare disease affecting teenagers who initially develop 1 to 2mm erythematous papules that become brownish hyperkeratotic 4 to 5mm papules, which coalesce with a peripheral reticulate pattern. The lesions occur over the trunk and extensor surfaces sparing the mucous membranes.[1] Gougerot and Carteaud first described confluent pigmented reticulated papillomatosis in 1927 and 1932.[2,3] Wise described the first case in the United States 10 years later.[4] Two other variants are nummular and punctate papillomatosis. Familial cases have been noted. The prevalence of males to females and African Americans to Caucasians is debatable as many cases are not reported.[5]. There has been a constant argument as to the classification of Gougerot-Carteaud syndrome; however, it is generally agreed that it is a distinct entity from acanthosis nigricans. Some authors feel it may represent an endocrine disturbance including a relation to Cushings disease, irregular ...
Mutations have been identified in the insulin-receptor gene in insulin-resistant patients. We studied two patients with acanthosis nigricans and insulin resistance caused by a decrease in the number of cell surface insulin receptors. Patient 1 was an 11-yr-old boy with a fasting insulin level of 2130 pM; patient 2 was a 14-yr-old girl with hyperandrogenism and a fasting insulin level of 580-740 pM. Based on Southern-blotting studies, the structure of both alleles of the insulin-receptor gene in both patients appeared to be grossly normal. There was no evidence of insertions, deletions, or major rearrangements. Moreover, the nucleotide sequences of all 22 exons of the gene were normal in both patients. Thus, the predicted amino acid sequences of both patients insulin receptors were normal. In Epstein-Barr virus-transformed lymphoblasts from patient 1, insulin-receptor mRNA levels were so low they could not be detected with an RNase A protection assay, whereas mRNA levels from patient 2 were in ...
Abstract Background The metabolic syndrome is associated with increased risk for both diabetes and coronary artery disease, which insulin resistance alone does not satisfactorily explain. We propose an additional and complementary underlying mechanism of glucocorticoid resistance. Results Using acanthosis nigricans (AN) and skin vasoconstrictor (SVC) response to topically applied beclomethasone dipropionate as markers of insulin and glucocorticoid resistance, respectively, we compared anthropometric, biochemical, pro-inflammatory markers and the SVC response in subjects with AN in two studies: STUDY 1 was used to compare subjects with AN (Grade 4, n = 32), with those without AN (n = 68) while STUDY 2 compared these responses among a cross-section of diabetic patients (n = 109) with varying grades of AN (grade 0, n = 30; grade 1, n = 24; grade 2, n = 18; grade 3, n = 25; grade 4, n = 12). Findings In both studies there was an inverse relationship between AN Grade 4 and the SVC response, (P andlt; ...
Background: Congenital generalized lipodystrophy (LCG) or Seip Berardinelli Syndrome is an autosomal resessive rare disease with a prevalence of one in 10 million live births and characterized an absence of adipose tissue and alterations in carbohydrates metabolism and diabetes mellitus, hypertrigliyceridemia, hypertrophic cardiomyopathy, hepatomegaly caused by fatty infiltration which may lead to cirrosis and polycystic ovary syndrome. The challenge is to prevent these complications thereby preventing death. Current management consists of metformin and recombinant leptin but the latter is associated with resistance due to antibody formation. The low pevalence of the disease prevents the findings of new therapies.. Objective and hypotheses: To describe a case of Seip Berardinelli syndrome.. Method: A 15-year-old adolescents female presents with severe acanthosis nigricans and amenorrhea. Height 147 cm, weight 41 kg, triangular fascies, absence of Bichat s ball, micrognathia, acromegaloid ...

As we learn more and more about the regulation of the insulin signaling network, a key question is, how is insulin signaling regulated in the pathophysiology of human disease? Recent studies in both animals and human tissues have demonstrated that both genetic and nongenetic factors can regulate insulin signaling by changing the sequence, expression level, or covalent modification of proteins involved in the intracellular network of insulin action.. Genetic alterations in the insulin signaling proteins. Insulin receptor. Naturally occurring mutations of the insulin receptor are rare, and the phenotype, when present, is usually a syndrome of extreme insulin resistance, such as leprechaunism or the type A syndrome of insulin resistance and acanthosis nigricans. Since the first reports in 1988 (77, 78), over 100 such cases have been identified. Genomic analysis has indicated that mutations of the insulin receptor itself do not play an important role in the pathophysiology of typical type 2 diabetes ...
Metabolic syndrome is a group of risk factors (linked to insulin resistance and adipose tissue dysfunction) that increases the risk for coronary heart disease, type 2 diabetes, stroke, fatty liver, and cancer. Although guidelines are available, metabolic syndrome remains underdiagnosed; therefore, we should aim for early diagnosis and interventions targeting risk reduction. Metabolic syndrome can manifest in a number of ways, including abdominal obesity, reduced HDL cholesterol, hypertriglyceridemia, hyperglycemia, and hypertension. Patients may experience chest pain or shortness of breath, which can suggest there is a rise of cardiovascular and other complications; acanthosis nigricans, hirsutism, peripheral neuropathy, and retinopathy can appear in patients with insulin resistance and hyperglycemia or with diabetes mellitus; and xanthomas or xanthelasmas can occur in patients with severe dyslipidemia ...

Confluent and reticulated papillomatosis (CARP) was first described ,60 years ago. It is distinct from acanthosis nigricans. This article presents the results of a review of the literature in MEDLINE through May 2006 using the terms confluent and reticulated papillomatosis, reticulated and confluent papillomatosis of Gougerot and Carteaud, and reticulated papillomatosis. A recent report has linked the presence of Dietzia spp. (family: Dietziaceae; suborder: Corynebacterineae; order: Actinomycetales) in the skin to CARP. CARP has also been linked to defects in keratinization. CARP has been reported worldwide and occurs in both sexes, all age groups, and all races. The disorder can initially manifest as hyperkeratotic or verrucous papules that coalesce to form a reticular pattern peripherally and confluent plaques centrally. Although a variety of treatments for CARP exist, oral minocycline 50-100mg twice daily has been the preferred treatment. However, recent reports of the effectiveness of ...

SADDAN (severe achondroplasia with developmental delay and acanthosis nigricans) is a rare disorder of bone growth characterized by skeletal, brain, and skin abnormalities.. All people with this condition have extremely short stature with particularly short arms and legs. Other features include unusual bowing of the leg bones; a small chest with short ribs and curved collar bones; short, broad fingers; and folds of extra skin on the arms and legs. Structural abnormalities of the brain cause seizures, profound developmental delay, and intellectual disability. Several affected individuals also have had episodes in which their breathing slows or stops for short periods (apnea). Acanthosis nigricans, a progressive skin disorder characterized by thick, dark, velvety skin, is another characteristic feature of SADDAN that develops in infancy or early childhood. ...

IgE-mediated reactions. Rhizopus nigricans is responsible for opportunistic infections and hypersensitivity reactions such as symptoms of asthma and hypersensitivity pneumonitis in sensitised individuals, and is an important occupational allergen. (51, 27, 28, 29). It has been postulated that fungi may contribute to increased severity of asthma. A study evaluating skin-prick tests and the prevalence of allergy to 15 mould allergens in 105 hospitalised patients with exacerbation of asthma found that sensitivity to Aureobasidium pullulans was significantly associated with more severe asthma. Sensitisation to Helminthosporium was associated with an increased number of asthma exacerbations that required hospitalisation. Of this group, 21 (20%) were sensitised to R. nigricans. (30). A number of studies have evaluated the prevalence of sensitisation to moulds in various population groups and geographical regions.. Almost 11% of patients with sensitivity to fungal allergens attending a clinic in India ...

One of the best constituents of raw green tripe is lactobacillus acidophilus. This is one of the intestinal bacteria that keep unwanted bacteria such as e-coli, salmonella, and listeria from overpopulating and causing health problems.. Another beneficial component of raw green tripe is digestive enzymes. The enzymes that help the ruminant digest its meal will give the pet the same benefit. Dogs do not naturally produce amylase, so the nutrients present in the vegetative matter are not readily available to them. Raw green tripe contains not only digestive enzymes but in most cases, some pre-digested green matter as well. This combination of enzymes and nutrients provide pets with a nutritional powerhouse.. There are a few options available if youre looking into feeding tripe to your dog. Canned or raw are the most popular and readily available options. Unfortunately with the canned option the nutrients we desire are cooked out during the heating process and most of the time there are unwanted ...

As I sent you a list of the land-shells picked up at Down when we were last there1 I wish you, in case you have kept it to put ?? to Helix carthusiana which I still think is among them- But the shell which I meant by that name is I find called by Forbes & Hanley Helix Cantiana Mont. as being the prior name-2 In my own list & perhaps in the one I sent you I find I had added this name of Montagues3 as a synonym-, for I had made no mistake about the species which I meant-. I also find amongst them another shell which I suppose to be Helix rufescens? and the Bulimus which I left unnamed must I think be B. obscurus- The Clausilia which I called C. plicatula ought to have been C. nigricans, according to Forbes & Hanley.. I have met with such a remarkably conical variety of Helix aspersa from Charing Kent, in Woodward collection4 that I cannot regard that shell as quite so constant in England as I told you-& as it is reputed to be.

HPV can infect any type of squamous epithelium and establishes a chronic infection in the epithelial basal layer. As basal cells differentiate, HPV viruses replicate, assemble, and are ultimately shed with sloughed epithelial cells. The virus synthesizes two proteins, E6 and E7, which promote proliferation of epithelial cells, resulting in expansion of all the squamous epitheliums layers. In skin this manifests as acanthosis, parakeratosis, and hyperkeratosis. Certain serotypes of HPV, especially serotypes 16 and 18, are especially oncogenic and are associated with a variety of epithelial neoplasms, especially cervical cancer ...
