Report: Cutaneous disorders in uremic patients on hemodialysis: an Egyptian case-controlled study

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 9 2010
Enas A. S. Attia MD
Summary Background, We studied the prevalence of mucocutaneous disorders in uremic adults and children on hemodialysis (HD) vs. controls, in Egypt. Methods, A total of 206 Egyptians with uremia (163 adults and 43 children) undergoing HD, and 199 healthy controls (161 adults and 38 children), were examined for mucocutaneous abnormalities. Results, Specific cutaneous diseases associated with renal insufficiency were found in five adults, including acquired perforating dermatosis and pseudo-porphyria. Non-specific abnormalities included xerosis (54%), pallor (42.2%), nail changes (34.9%), hair changes (34%), pruritus (32%), hyper-pigmentation (22.2%), coated tongue (14.1%), ecchymosis (1.5%), and gingival hypertrophy (1.5%). Disorders found significantly more often in uremics than controls included pallor, nail changes, hair changes, pruritus, hyper-pigmentation and coated tongue in adults (P < 0.05), and nail changes, hair changes, and hyper-pigmentation in children (P < 0.05). The prevalence of each mucocutaneous abnormality was similar in uremic adults and children except for pallor [more common in adults (P = 0.001)], and hyper-pigmentation [more common in children (P = 0.003)]. A greater number of hepatitis C virus-positive than -negative adult uremics had hyper-pigmentation (P < 0.05), and more diabetic uremics had pruritus than did non-diabetics (P < 0.05). Conclusion, Mucocutaneous disorders occur in adults and children with uremia, some of which are specific associations with the underlying renal disease. Occurrence of some of the non-specific abnormalities, such as xerosis, ecchymosis, and gingival hypertrophy, may be coincidental or associated with factors other than renal insufficiency. [source]


Cutaneous disorders in the "bairro Inhamudima" of Beira, Mozambique

Background, There are no reliable data on the prevalence of skin diseases in Mozambique. Aim, To address this issue and to apply the findings to the dermatology teaching program at the Universidade Católica de Moçambique. Methods, Medical students attempted to identify the most common skin disorders in the "bairro Inhamudima" of Beira, Mozambique by conducting a population survey. During a 3-month period, the students visited families in a slum area. Information on gender, age, human immunodeficiency virus status, cutaneous abnormalities, diagnosis, treatment, and clinical course was recorded. Results, Eleven per cent of the study population suffered from cutaneous disease. More than half the patients (57%) sought medical assistance, but 39% could not be diagnosed by the medical students. The most common disorder was scabies. Other problems included fungal infections, viral infections, allergies, and dermatitis with or without secondary bacterial infection. Conclusions, There is a major dermatologic need in the slum areas of Beira, Mozambique. The dermatology teaching program should pay particular attention to training in the diagnosis and management of infections and infestations. [source]


Pemphigus Foliaceus Masquerading as Postoperative Wound Infection: Report of a Case and Review of the Koebner and Related Phenomenon following Surgical Procedures

DERMATOLOGIC SURGERY, Issue 2 2005
Adam M. Rotunda MD
Background The Koebner phenomenon, also known as the isomorphic response, is the development of preexisting skin disease following trauma to uninvolved skin. Various cutaneous disorders have been described to arise at surgical wounds and scars. Moreover, dermatologic procedures, such as cold-steel and laser surgery, can evoke koebnerization. Objective To describe a case of pemphigus foliaceus arising in postoperative wounds and to present a review of dermatologic disorders triggered by surgical procedures. Methods We report a case of pemphigus foliaceus initially presenting at sites of Mohs' micrographic surgery, shave biopsy, and cryotherapy and, subsequently, at a nonsurgical site. We reviewed the English literature in MEDLINE from November 1955 to April 2004 for reports of Koebner and related phenomenon following surgical procedures. Results To our knowledge, this is the first reported case of pemphigus foliaceus erupting at surgical and cryotherapy wounds. The clinical appearance can mimic wound infection. In addition to inducing preexisting disease, cutaneous procedures can also trigger the onset of new disease, which can either be limited only to the surgical site or subsequently become generalized. Conclusion Postoperative Koebner or related responses should be included in the differential diagnosis of poorly healing surgical wounds. Skin biopsies for histopathology and immunologic studies may be necessary for definitive diagnosis and optimal management. ADAM M. ROTUNDA, MD, ANAND R. BHUPATHY, DO, ROBERT DYE, MD, AND TERESA T.

GB virus type C infection in hemodialysis patients considering co-infection with hepatitis C virus

JOURNAL OF MEDICAL VIROLOGY, Issue 7 2008

Abstract GB virus type C is a well-known viral agent with capability of infecting patients undergoing hemodialysis. Liver enzyme levels in infected individuals have been reported to remain within the normal range. Simultaneous infection of GBV-C and other viral agents may occur due to common routes of transmission. A total of 104 hemodialysis patients living in Tehran were included in this case-control study (53 patients with HCV infection, group I; and 51 with no HCV infection, group II). Diagnosis was made by detection Anti-E2 protein using ELISA and HCV,RNA using RT-PCR. History of HBV-infection, organ transplantation, depression, malignancies, chemotherapy, diabetes mellitus, thyroid disorders and chronic cutaneous disorders were considered. Patients were evaluated for high- risk behaviors such as intravenous drug injection, addiction or substance abuse. A total of 14 patients (13.6%) were GBV-C-infected. Four of them were co-infected with HCV. All patients with GBV-C infection had viral genotype 2. Thirteen patients (12%) had a history of multiple blood transfusions. Mean (±SD) age of GBV-C-infected patients was 48.7,±,13.8 years. Among GBV-C infected patients, three patients had a history of organ transplantation and three had a co-morbidity of diabetes mellitus. This study as the first case-control study to evaluate the association between GBV-C and HCV infection, to our knowledge, shows hemodialysis patients living in Tehran are infected with GBV-C with intermediate level of frequency. The association of GBV-C transmission with other viral blood-borne agents might be necessary. J. Med. Virol. 80: 1260,1263, 2008. © 2008 Wiley-Liss, Inc. [source]
