1/61. Successful treatment of acquired perforating dermatosis with rifampicin in an Asian patient with sclerosing cholangitis.Acquired perforating dermatosis (APD) is a very rare disorder which has been described in association with systemic diseases such as diabetes mellitus, hiv infection or lymphoma. In this report we describe a patient with APD associated with sclerosing cholangitis and diabetes mellitus who was successfully treated with rifampicin. A 33-year-old Indian woman with a history of extensive pancreatic surgery, sclerosing cholangitis and insulin dependent diabetes mellitus was referred to our unit with intractable pruritus. She was treated with cholestyramine, ursodeoxycholic acid, several analgesics, UVB therapy, topical steroids, sedative antihistamines and plasmapheresis without significant improvement. Increasingly severe itching was associated with papular skin changes limited initially to the lower limbs but which later involved her entire body. biopsy of a representative lesion showed the changes of APD. She was subsequently treated with rifampicin which produced a dramatic resolution of pruritus within 3 weeks and the skin changes progressively resolved over subsequent months. In this newly described association of APD with sclerosing cholangitis, rifampicin treatment appeared to be efficient in ameliorating pruritus and the papular skin changes typical of APD.- - - - - - - - - - ranking = 1keywords = diabetes mellitus, diabetes, mellitus (Clic here for more details about this article) |
2/61. Acquired perforating dermatosis in diabetes mellitus: an unusual case.A case of elastosis perforans serpiginosa in a patient who presented with insulin-dependent diabetes mellitus secondary to pancreatic insufficiency in a background of common variable immunodeficiency and endocrinopathy, as evidenced by pernicious anaemia and growth hormone deficiency, is described. In acquired perforating dermatosis occurring in patients with diabetes or renal failure, there is a spectrum of changes that may show an overlap of histological features of the four classic perforating diseases. The biopsy changes of the patient described in the present study most closely resembled those of elastosis perforans serpiginosa.- - - - - - - - - - ranking = 1.7188239382107keywords = diabetes mellitus, diabetes, mellitus (Clic here for more details about this article) |
3/61. Necrotizing fasciitis after cosmetic blepharoplasty.PURPOSE: To report a case of necrotizing fasciitis after cosmetic blepharoplasty. METHOD: Case report. A 74-year-old woman with history of type II diabetes mellitus underwent bilateral upper eyelid blepharoplasty. Postoperatively she developed fever, grayish discoloration of the skin, violaceous bullae, and a right facial nerve palsy. Necrotizing fasciitis was diagnosed and treated with intravenous antibiotics, debridement of necrotic tissue, and hyperbaric oxygen therapy. RESULTS: The infection resolved, but the patient required reconstruction for correction of cicatricial ectropion. CONCLUSION: Necrotizing fasciitis is a potentially fatal infection that typically occurs in the setting of trauma. Early recognition of its pathognomonic signs and aggressive management are paramount.- - - - - - - - - - ranking = 0.33333333333333keywords = diabetes mellitus, diabetes, mellitus (Clic here for more details about this article) |
4/61. Troglitazone improves psoriasis and normalizes models of proliferative skin disease: ligands for peroxisome proliferator-activated receptor-gamma inhibit keratinocyte proliferation.BACKGROUND: psoriasis is often treated with agents that activate nuclear hormone receptors for glucocorticoids, retinoids, and vitamin d. The peroxisome proliferator-activated receptor-gamma (PPARgamma) is a related nuclear hormone receptor that can be activated by its ligands, including the thiazolidinediones. OBJECTIVE: To assess whether treatment with troglitazone, a currently available thiazolidinedione used to treat diabetes mellitus, has an effect on psoriasis in normoglycemic patients and whether ligands for PPARgamma have an effect on models of psoriasis. DESIGN: Open-label administration of troglitazone in patients with psoriasis and evaluation of drug actions in cellular, organ, and transplant models of psoriasis. SETTING: University and community hospital outpatient departments and university laboratories. patients: patients with chronic, stable plaque psoriasis and control subjects. Five patients with psoriasis received troglitazone (none withdrew); 10 different untreated patients and 10 controls provided tissue samples. INTERVENTIONS: Oral troglitazone therapy at various dosages in patients with psoriasis; also, use of troglitazone, ciglitazone, and 15-deoxy-delta-12,14-prostaglandinJ2 in psoriasis models. MAIN OUTCOME MEASURES: Investigator-determined clinical results in patients and cell counts and histological evidence in models. RESULTS: All patients' psoriasis improved substantially during troglitazone therapy. Peroxisome proliferator-activated receptor-gamma was expressed in human keratinocytes; ligands for PPARgamma inhibited the proliferation of normal and psoriatic human keratinocytes in culture. Troglitazone treatment normalized the histological features of psoriatic skin in organ culture and reduced the epidermal hyperplasia of psoriasis in the severe combined immunodeficient mouse and human skin transplant model of psoriasis (P<.05 compared with untreated controls). CONCLUSIONS: Peroxisome proliferator-activated receptor-gamma might be a useful intracellular target for the treatment of psoriasis; further study is needed to assess the clinical value of ligands for PPARgamma, including troglitazone.- - - - - - - - - - ranking = 0.33333333333333keywords = diabetes mellitus, diabetes, mellitus (Clic here for more details about this article) |
5/61. Benign cephalic histiocytosis with diabetes insipidus.Benign cephalic histiocytosis is a rare skin condition consisting of small tan papules on the face and upper trunk that is believed not to be associated with internal organ involvement. The infiltrating histiocytes are not Langerhans' cells (LCs). We report a 5-year-old girl who presented with diabetes insipidus 1 year after developing multiple small brown asymptomatic skin papules. Histologic examination revealed a non-LC histiocytic proliferation in the dermis without epidermal invasion. She had infiltration of the pituitary stalk on brain imaging. diabetes insipidus has heretofore been associated with LC histiocytosis and xanthoma disseminatum but not benign cephalic histiocytosis.- - - - - - - - - - ranking = 0.26078635772004keywords = diabetes (Clic here for more details about this article) |
6/61. Acquired reactive perforating collagenosis in a diabetic patient with pulmonary aspergillosis.Reactive perforating collagenosis (RPC) is a rare disorder characterized by transepidermal elimination of altered collagen. The acquired form of RPC manifests in adult life and is accompanied by general pruritus and scratching. diabetes mellitus and end-stage renal disease are frequently associated with RPC. We describe a case of RPC developing after pulmonary aspergillosis in a 54-year-old man with long-standing insulin-dependent diabetes and discuss possible etiologic relations.- - - - - - - - - - ranking = 0.10342734223368keywords = diabetes, mellitus (Clic here for more details about this article) |
7/61. Acquired reactive perforating collagenosis.Acquired perforating disorder has been recognized as an uncommon distinct dermatosis in which altered collagen is eliminated through the epidermis.

8/61. necrobiotic xanthogranuloma without periorbital involvement: an ultrastructural investigation.A case of necrobiotic xanthogranuloma without typical periorbital involvement is described at the ultrastructural level. The patient, a 58-year-old Italian man, presented in 1995 with a brief history of nodulo-papular lesions commencing on the lower limbs, and mild paraproteinemia. During 6 years of follow-up, anemia, neutropenia with marked lymphopenia, and increased ESR were found, while serum cholesterol and triglyceride levels decreased from hyper to hypo values. Systemic diseases, such as diabetes, malignancy, or extracutaneous lesions, often associated with NXG, have not developed. Conventional histology was distinctive for NXG, and immunohistochemistry confirmed that dermal histiocytes were not of Langerhans cell lineage. At ultrastructure, regeneration and degeneration ("regen-degen") features were observed in some individual deep dermal histiocytes, which have not been previously documented in the literature. Identification of giant histiocytes showing 'regen-degen'' aspects might prove to be a useful ultrastructural diagnostic marker for NXG.- - - - - - - - - - ranking = 0.052157271544008keywords = diabetes (Clic here for more details about this article) |
9/61. Acquired reactive perforating collagenosis: report of a case and review of the literature.A case of acquired reactive perforating collagenosis is reported in a 57-year-old Thai woman, with a history of diabetes mellitus, chronic renal insufficiency needing hemodialysis, and dry gangrene of the right fourth toe. physical examination revealed multiple scattered erythematous hyperkeratotic nodules and plaques and some showed ulceration. Histopathology showed vertical strands of collagen perforating from the ulcerated lesions. The authors also reviewed the literature on this subject.- - - - - - - - - - ranking = 0.33333333333333keywords = diabetes mellitus, diabetes, mellitus (Clic here for more details about this article) |
10/61. A new clinical condition linked to a novel mutation in lamins A and C with generalized lipoatrophy, insulin-resistant diabetes, disseminated leukomelanodermic papules, liver steatosis, and cardiomyopathy.A-Type lamins, arising from the LMNA gene, are intermediate filaments proteins that belong to the lamina, a ubiquitous nuclear network. Naturally occurring mutations in these proteins have been shown to be responsible for several distinct diseases that display skeletal and/or cardiac muscle or peripheral nerve involvement. These include familial partial lipodystrophy of the Dunnigan type and the mandibuloacral dysplasia syndrome. The pathophysiology of this group of diseases, often referred to as laminopathies, remains elusive. We report a new condition in a 30-yr-old man exhibiting a previously undescribed heterozygous R133L LMNA mutation. His phenotype associated generalized acquired lipoatrophy with insulin-resistant diabetes, hypertriglyceridemia, hepatic steatosis, hypertrophic cardiomyopathy with valvular involvement, and disseminated whitish papules. Immunofluorescence microscopic analysis of the patient's cultured skin fibroblasts revealed nuclear disorganization and abnormal distribution of A-type lamins, similar to that observed in patients harboring other LMNA mutations. This observation broadens the clinical spectrum of laminopathies, pointing out the clinical variability of lipodystrophy and the unreported possibility of hypertrophic cardiomyopathy and skin involvement. It emphasizes the fact that the diagnosis of genetic alterations in A-type lamins requires careful and complete clinical and morphological investigations in patients regardless of the presenting signs.- - - - - - - - - - ranking = 0.26078635772004keywords = diabetes (Clic here for more details about this article) |
