Trichophyton violaceum: a rare isolate in 18-day-old neonate

Trichophyton violaceum, a less common and geographically restricted infection is reported in a 18-day-old neonate. The diagnosis was made by potassium hydroxide of skin scraping examination and confirmed by culture. The patient was treated successfully with miconazole nitrate application. A large family with crowded living was considered the main predisposing factor.     

Liver histology in patients on hemodialysis with chronic hepatitis C viral infection

Hepatitis C virus (HCV) is a major cause of chronic liver disease in patients on hemodialysis. As no useful noninvasive predictors of disease activity and fibrosis have been found, liver biopsy is essential in these patients to accurately assess the severity of disease and thus the prognosis and plan management. The present study was undertaken to assess the degree of severity of necroinflammatory changes and fibrosis in liver biopsies of patients on hemodialysis with chronic HCV infection. Liver biopsies obtained from 45 patients on hemodialysis with serological evidence of chronic hepatitis C were studied. The grading of necroinflammatory activity and staging of fibrosis were histologically assessed. The majority of patients (30, i.e. 66.7%) had mild disease with mild inflammatory activity and stage 0, 1 or 2 fibrosis. There was no significant correlation between the degree of fibrosis and the age of the patients (rs = 0.015), the duration of hemodialysis (rs = 0.047) or the presence of steatosis (rs = 0.064). There was a positive correlation between the presence of bile ductular proliferation and the severity of fibrosis (rs = 0.612). It was concluded that chronic HCV infection in hemodialysis patients is relatively mild early in its course. However, serial follow-up liver biopsies are mandatory to plan appropriate intervention strategies.

CYP1A1 gene polymorphisms: lack of association with breast cancer susceptibility in the southern region (Madurai) of India

The cytochrome P 450 1A1 gene encoding a phase I metabolic enzyme appears to be a candidate for breast cancer risk. It is involved in the phase I detoxification of polycyclic aromatic hydrocarbons (PAHs) and 2-hydroxylation of estrogens and mammary carcinogens into 2-hydroxy catechol metabolites. Several studies have investigated polymorphisms in CYP1A1 and breast cancer risk with inconsistent results. We here carried out a population based case-control study of the CYP MspI (CYP1A1*1/M1) and Ile462Val (CYP1A1*2/M2) polymorphisms in CYP1A1 to clarify their importance in determining breast cancer susceptibility in a South Indian population. A total of 50 cases and 50 controls were genotyped for both polymorphisms. We also investigated putative interactions with exposure to pollution, radiation and intake of tobacco and CYP1A1 genotype and breast cancer risk using a case only study design. The genotype distribution of CYP1A1*1 in cancer patients was 6% for homozygous (CYP1A1 M1 [C/C], 34% for heterozygous CYP1A1 M1 [T/C] and 60% for wild type (CYP1A1 M1 [T/T] (OR: 0.583, CI-95% (0.252-1.348). The genotype distribution of M2 genotypes in patients was 24% of homozygous (CYP1A1 M2 [Val/Val], 4% for heterozygous (CYP1A1 M2 [Ile/Val] and 72% for wild type allele (CYP1A1 M2 [Ile/Ile] [OR: 0.720, CI-95% (0.606-0.856)]. Our results suggest that there is no significant correlation between CYP1A1 M1/ CYP1A1 M2 polymorphism and occurrence of breast cancer in South Indian women.     

Corneal perforation due to limbal involvement in Sézary syndrome

Background  

The majority of lymphomas involving the eye and ocular adnexa are B-cell lymphomas. Ocular involvement by T-cell lymphoma is rare. We report a case of corneal perforation due to direct involvement of the corneal limbus by lymphoma in a patient with Sézary syndrome.
