Globosides: Glycosphingolipids containing N-acetylglucosamine (paragloboside) or N-acetylgalactosamine (globoside). Globoside is the P antigen on erythrocytes and paragloboside is an intermediate in the biosynthesis of erythrocyte blood group ABH and P 1 glycosphingolipid antigens. The accumulation of globoside in tissue, due to a defect in hexosaminidases A and B, is the cause of Sandhoff disease.Scalp: The outer covering of the calvaria. It is composed of several layers: SKIN; subcutaneous connective tissue; the occipitofrontal muscle which includes the tendinous galea aponeurotica; loose connective tissue; and the pericranium (the PERIOSTEUM of the SKULL).Hair Follicle: A tube-like invagination of the EPIDERMIS from which the hair shaft develops and into which SEBACEOUS GLANDS open. The hair follicle is lined by a cellular inner and outer root sheath of epidermal origin and is invested with a fibrous sheath derived from the dermis. (Stedman, 26th ed) Follicles of very long hairs extend into the subcutaneous layer of tissue under the SKIN.Hair: A filament-like structure consisting of a shaft which projects to the surface of the SKIN from a root which is softer than the shaft and lodges in the cavity of a HAIR FOLLICLE. It is found on most surfaces of the body.Minoxidil: A potent direct-acting peripheral vasodilator (VASODILATOR AGENTS) that reduces peripheral resistance and produces a fall in BLOOD PRESSURE. (From Martindale, The Extra Pharmacopoeia, 30th ed, p371)Scalp DermatosesFolliculitis: Inflammation of follicles, primarily hair follicles.Dermoscopy: A noninvasive technique that enables direct microscopic examination of the surface and architecture of the SKIN.Tinea Capitis: Ringworm of the scalp and associated hair mainly caused by species of MICROSPORUM; TRICHOPHYTON; and EPIDERMOPHYTON, which may occasionally involve the eyebrows and eyelashes.Trichotillomania: Compulsion to pull out one's hair.Cicatrix: The fibrous tissue that replaces normal tissue during the process of WOUND HEALING.Photophobia: Abnormal sensitivity to light. This may occur as a manifestation of EYE DISEASES; MIGRAINE; SUBARACHNOID HEMORRHAGE; MENINGITIS; and other disorders. Photophobia may also occur in association with DEPRESSION and other MENTAL DISORDERS.Lichen Planus: An inflammatory, pruritic disease of the skin and mucous membranes, which can be either generalized or localized. It is characterized by distinctive purplish, flat-topped papules having a predilection for the trunk and flexor surfaces. The lesions may be discrete or coalesce to form plaques. Histologically, there is a "saw-tooth" pattern of epidermal hyperplasia and vacuolar alteration of the basal layer of the epidermis along with an intense upper dermal inflammatory infiltrate composed predominantly of T-cells. Etiology is unknown.Eyebrows: Curved rows of HAIR located on the upper edges of the eye sockets.Triethylenephosphoramide: An insect chemosterilant and an antineoplastic agent.Hypotrichosis: Presence of less than the normal amount of hair. (Dorland, 27th ed)Skin: The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.Ichthyosis: Any of several generalized skin disorders characterized by dryness, roughness, and scaliness, due to hypertrophy of the stratum corneum epidermis. Most are genetic, but some are acquired, developing in association with other systemic disease or genetic syndrome.Sebaceous Glands: Small, sacculated organs found within the DERMIS. Each gland has a single duct that emerges from a cluster of oval alveoli. Each alveolus consists of a transparent BASEMENT MEMBRANE enclosing epithelial cells. The ducts from most sebaceous glands open into a HAIR FOLLICLE, but some open on the general surface of the SKIN. Sebaceous glands secrete SEBUM.

(1/646) Phase II trial of paclitaxel and cisplatin in metastatic and recurrent carcinoma of the uterine cervix.

PURPOSE: Both paclitaxel and cisplatin have moderate activity in patients with metastatic or recurrent cancer of the cervix, and the combination of these two agents has shown activity and possible synergism in a variety of solid tumors. We administered this combination to patients with metastatic or recurrent cervical cancer to evaluate its activity. PATIENTS AND METHODS: Thirty-four consecutive patients were treated on an outpatient basis with paclitaxel 175 mg/m2 administered intravenously over a 3-hour period followed by cisplatin 75 mg/m2 administered intravenously with granulocyte colony-stimulating factor support. The chemotherapy was administered every 3 weeks for a maximum of six courses. RESULTS: Sixteen patients (47%; 95% confidence interval, 30% to 65%) achieved an objective response, including five complete responses and 11 partial responses. Responses occurred in 28% of patients with disease within the radiation field only and in 57% of patients with disease involving other sites. The median duration of response was 5.5 months, and the median times to progression and survival for all patients were 5 and 9 months, respectively. Grade 3 or 4 toxicities included anemia in 18% of patients and granulocytopenia in 15% of patients. Fifty-three percent of patients developed some degree of neurotoxicity; 21% of cases were grade 2 or worse. CONCLUSION: The combination of paclitaxel with cisplatin seems relatively well tolerated and moderately active in patients with metastatic or recurrent cervical cancer. The significant incidence of neurotoxicity is of concern, and alternative methods of administration of the two agents could be evaluated. Then, further study of this combination, alone or with the addition of other active agents, is warranted.  (+info)

(2/646) Phase I-II study of gemcitabine and carboplatin in stage IIIB-IV non-small-cell lung cancer.

PURPOSE: Platinum-based chemotherapy currently represents standard treatment for advanced non-small-cell lung cancer. Gemcitabine is one of the most interesting agents currently in use in advanced non-small-cell lung cancer, and high response rates have been reported when it is administered in combination with cisplatin. The aim of the present study was to evaluate the combination of gemcitabine and carboplatin in a phase I-II study. PATIENTS AND METHODS: Chemotherapy-naive patients with stage IIIB-IV non-small-cell lung cancer received carboplatin at area under the concentration-time curve (AUC) 5 mg/mL/min and gemcitabine at an initial dose of 800 mg/m2, subsequently escalated by 100 mg/m2 per step. Gemcitabine was administered on days 1 and 8 and carboplatin on day 8 of the 28-day cycle. Dose escalation proceeded up to dose-limiting toxicity (DLT), which was defined as grade 4 neutropenia or thrombocytopenia or grade 3 nonhematologic toxicity. RESULTS: Neutropenia was DLT, inasmuch as it occurred in three of five patients receiving gemcitabine 1,200 mg/m2. Nonhematologic toxicities were mild. Gemcitabine 1,100 mg/m2 plus carboplatin AUC 5 was recommended for phase II studies. An objective response was observed in 13 (50%) of 26 patients, including four complete responses (15%) and nine partial responses (35%). Median duration of response was 13 months (range, 3 to 23 months). Median overall survival was 16 months (range, 3 to 26 months). CONCLUSION: The combination of gemcitabine and carboplatin is well tolerated and active. Neutropenia was DLT. The observed activity matches that observable in cisplatin-gemcitabine studies, whereas duration of response and survival are even higher. A phase II trial is under way.  (+info)

(3/646) Longevity, stress response, and cancer in aging telomerase-deficient mice.

Telomere maintenance is thought to play a role in signaling cellular senescence; however, a link with organismal aging processes has not been established. The telomerase null mouse provides an opportunity to understand the effects associated with critical telomere shortening at the organismal level. We studied a variety of physiological processes in an aging cohort of mTR-/- mice. Loss of telomere function did not elicit a full spectrum of classical pathophysiological symptoms of aging. However, age-dependent telomere shortening and accompanying genetic instability were associated with shortened life span as well as a reduced capacity to respond to stresses such as wound healing and hematopoietic ablation. In addition, we found an increased incidence of spontaneous malignancies. These findings demonstrate a critical role for telomere length in the overall fitness, reserve, and well being of the aging organism.  (+info)

(4/646) Increased risk of chronic graft-versus-host disease, obstructive bronchiolitis, and alopecia with busulfan versus total body irradiation: long-term results of a randomized trial in allogeneic marrow recipients with leukemia. Nordic Bone Marrow Transplantation Group.

Leukemic patients receiving marrow from HLA-identical sibling donors were randomized to treatment with either busulfan 16 mg/kg (n = 88) or total body irradiation ([TBI] n = 79) in addition to cyclophosphamide 120 mg/kg. The patients were observed for a period of 5 to 9 years. Busulfan-treated patients had an increased risk of veno-occlusive disease (VOD) of the liver (12% v 1%, P =.01) and hemorrhagic cystitis (32% v 10%, P =.003). Acute graft-versus-host disease (GVHD) was similar in the two groups, but the 7-year cumulative incidence of chronic GVHD was 59% in the busulfan-treated group versus 47% in the TBI group (P =.05). Death from GVHD was more common in the busulfan group (22% v 3%, P <.001). Obstructive bronchiolitis occurred in 26% of the busulfan patients but in only 5% of the TBI patients (P <.01). Complete alopecia developed in 8 busulfan patients and partial alopecia in 17, versus five with partial alopecia in the TBI group (P <.001). Cataracts occurred in 5 busulfan-treated patients and 16 TBI patients (P =.02). The incidence of relapse after 7 years was 29% in both groups. Seven-year transplant-related mortality (TRM) in patients with early disease was 21% in the busulfan group and 12% in the TBI group. In patients with more advanced disease, the corresponding figures were 64% and 22%, respectively (P =.004). Leukemia-free survival (LFS) in patients with early disease was 68% in busulfan-treated patients and 66% in TBI patients. However, 7-year LFS in patients with more advanced disease was 17% in the busulfan group versus 49% in the TBI group (P <.01). In patients with chronic myeloid leukemia (CML) in first chronic phase, 7-year LFS was 72% and 83% in the two groups, respectively.  (+info)

(5/646) Clomipramine-induced urinary retention in a cat.

A 10-year-old, female, spayed shorthair with presumed psychogenic alopecia was treated with clomipramine (1 mg/kg body weight/day). The cat developed urinary retention within 2 days. Clomipramine was discontinued. Clinical signs resolved over the next 7 days. The urinary retention was attributed to the anticholinergic effects of clomipramine.  (+info)

(6/646) Identification of a genetic defect in the hairless gene in atrichia with papular lesions: evidence for phenotypic heterogeneity among inherited atrichias.

Recently, we showed that atrichia with papular lesions (APL), a rare inherited form of alopecia, is transmitted as an autosomal recessive trait in a large inbred kindred of Israeli-Arab origin. Furthermore, we mapped the APL locus to a 5-cM region of chromosome 8p12 in this family. The human "hairless" gene is a candidate target gene for the disease mutation because it maps to the APL locus and because it was recently found to be mutated in a related but clinically distinct form of alopecia known as "alopecia universalis" or "congenital alopecia." In the present study, the coding sequence of the hairless gene was compared by reverse transcription-PCR in fibroblast cell lines derived from an affected patient and an unrelated individual. We identified a single-base deletion (3434delC) in the hairless gene that cosegregated with the disease phenotype in the family. This deletion is predicted to cause a frameshift mutation in the highly conserved C-terminal part of the hairless protein, a region putatively involved in the transcription factor activity of the hairless gene product. The present results are indicative of phenotypic heterogeneity in inherited atrichias caused by mutations in the hairless gene, suggesting different roles for the regions mutated in APL and in other forms of congenital atrichia during hair development.  (+info)

(7/646) Medical treatments for balding in men.

Two drugs are available for the treatment of balding in men. Minoxidil, a topical product, is available without a prescription in two strengths. Finasteride is a prescription drug taken orally once daily. Both agents are modestly effective in maintaining (and sometimes regrowing) hair that is lost as a result of androgenic alopecia. The vertex of the scalp is the area that is most likely to respond to treatment, with little or no hair regrowth occurring on the anterior scalp or at the hairline. Side effects of these medications are minimal, making them suitable treatments for this benign but psychologically disruptive condition.  (+info)

(8/646) Insulin gene polymorphism and premature male pattern baldness in the general population.

Insulin is found in hair follicles and may play a role in the regulation of androgen metabolism and the hair growth cycle, which are relevant to the loss of scalp hair known as male pattern baldness. An excess of dihydrotestosterone on balding scalp indicates that the condition is androgen dependent. Premature male pattern baldness may be the male phenotype of familial polycystic ovary syndrome, a condition characterized by high levels of androgens and insulin that has been linked to insulin gene polymorphism. Therefore, we studied possible associations between relevant insulin gene polymorphisms and premature male pattern baldness in the general community. We examined the distribution of three dimorphic restriction fragment length polymorphisms: HphI, PstI and FokI in cases consisting of 56 men aged 18-30 years with significant baldness, and in 107 control men aged 50 years or more with no indication of baldness. No significant differences between cases and controls in allele, genotype or haplotype frequencies were identified. We conclude that, in the general population, the insulin gene is not associated with premature male pattern baldness.  (+info)
