Mycosis fungoides with Psoriasiform plaques: A case report and review of the literature.

Mycosis fungoides (MF) is the most common variant of primary skin T-cell lymphoma. It typically manifests as an indolent progressing cutaneous eruption with erythematous scaly patches or plaques. Due to the nonspecific pathological findings, it can be easily misdiagnosed as psoriasis. A 34-year-old woman with a history of psoriasiform plaques for 12 years was referred to our dermatology clinic. In the beginning, the diagnosis of psoriasis was made and topical steroids were prescribed: it did not exhibit any clinical improvement. During the visit, skin biopsy was performed and the diagnosis of MF was confirmed. Treatment with PUVA, prednisolon, methotrexate, topical ointment including ucerin, urea, and clobetasol were initiated. Significant improvement in all lesions were observed after 1 month of the treatment, and within a year, the disease improved dramatically after PUVA therapy. In refractory cases of psoriasiform plaques that are progressive and/or ulcerative despite the optimal treatment, biopsy is required and a possible diagnosis of MF should be kept in mind.

Dermatomycosis in Cutaneous Tumors is a Predictor for Non-malignancy: A Cross-sectional Study.

The aim of this study was to evaluate the presence of spores and/or hyphae in benign cutaneous tumors (CT) and compare their presence in malignant cutaneous tumors. In this cross-sectional study we evaluated 328 CTs positive for spores and/or hyphae. The results show that the greatest number of involved CTs which contained spores and/or hyphae were found in compound nevi 181 (55.18%) and seborrheic warts 61 (18.60%). No spores and/or hyphae were observed in the melanoma samples, and a very low prevalence was found in squamous cell carcinomas (SCCs) (2; 0.61%) and basal cell carcinoma (BCC) (1; 0.30%). The presence of spores and/or hyphae could be a good indicator for non-malignancy, allowing differential diagnosis between benign CTs and SCCs or BCCs as well as between melanoma and nevi.

Seroepidemiology of toxoplasmosis in childbearing women of Northwest Iran.

Toxoplasma gondii causes the most common parasitic infection in the world. Congenital transmission, prenatal mortality and abortion are major problems of T. gondii. Prevalence of toxoplasmosis is high in Iran, especially in Azerbaijan. The current literature reviewed in this paper reveal results pertaining to various regions of Iran. The present cross-sectional e-study was designed to evaluate the seroprevalence of toxoplasmosis in childbearing women in Northwest Iran. We evaluated 1659 women in childbearing age from several cities in Northwestern Iran (Tabriz, Maragheh, Ahar, Marand, Sarab, Miane) from July 2009 to August 2010. Women aged between 20 and 40 years and seeking prenatal care were enrolled in the study. The subjects' sera were probed with indirect fluorescent antibody (IFA). A total of 1659 subjects were examined. Titres ranged from 1:100 to 1:800. In all, 899 subjects (54.13%) were seropositive. The highest frequency of seropositivity was shown in 1:200 dilution (36.08%) and in subjects from Maragheh (84% of 211 subjects). There was a direct linear relationship between seropositivity and age (p 0.001). Also, seroprevalence of toxoplasmosis was higher in subjects with primary school/lower educational level (p 0.001) and subjects living in rural regions (p 0.001). Overall, more than 50% of women in childbearing age were seropositive for toxoplasmosis in northwestern Iran. Increasing seroprevalence of toxoplasmosis with age was a predictable result due to longer exposure to the parasite. The relationship between increasing seroprevalence and lower educational level as well as living in rural areas is in line with the latest epidemiological findings, which also show such relationships due to lower socioeconomic status.

Renal vascular Doppler resistance after extracorporeal shock wave lithotripsy.

OBJECTIVES: Extracorporeal shock wave lithotripsy (ESWL) is mainly an alternative for other therapeutic methods such as surgery and endourology to treat urinary tract calculus. Although it is safe and effective, it has undesirable effects on renal function. Diagnostic techniques such as color Doppler ultrasonography create a new attitude toward renal function. The aim of this study was to evaluate renal vascular resistance change before and after extracorporeal shock wave lithotripsy. METHODS: During the present study, vascular resistive index (RI) of renal intralobar artery was measured before, 30 min, and 1 week after ESWL using Doppler ultrasonography. RESULTS: Thirty minutes after ESWL, RI was significantly increased from primary value of 0.62 ± 0.05 to 0.66 ± 0.06 (p = 0.0001). There was no correlation between increase of RI and patients' age. Following up the patients revealed that mean RI did not return to pretreatment level after 1 week (p < 0.05). The RI level in the old patients (3 patients who were 60 years or older) was higher than that of the younger ones (19 patients who were younger than 60 years) after 1 week (0.76 ± 0.05 vs. 0.64 ± 0.06). There was no meaningful relationship between ESWL voltage or number of shocks and RI variation before and after ESWL. CONCLUSION: Following ESWL, patients are at risk of renal tissue damage due to increase of primary RI level. Measuring RI variations using ultrasound techniques after ESWL may provide helpful information to clinical detection of renal tissue damage.

Cardiac findings in congenital nephrotic syndrome.

INTRODUCTION: Congenital nephrotic syndrome is a severe debilitating problem associated with extra renal manifestation such as diverse cardiac findings. METHODS: During four years, 6 cases diagnosed as congenital nephritic syndrome in base of definitive criteria their documents reviewed and echocardiographic evaluation has been done for all with or without cardiac sign or symptoms, results gathered and expressed as incidence. RESULTS: All cases have some grades of structural or functional defects from simple form like as tricuspid regurgitation to complex defects. It may be run in consecutively in siblings of a family from non consanguine parents. CONCLUSION: Pulmonary stenosis may occur in all parts subvalvualr, valvular and peripheral parts of pulmonary artery, left ventricular hypertrophy and mitral regurgitation observed in some, moderate tricuspid regurgitation observed in half of cases due to pulmonary hypertension or right ventricular hypertrophy due to pulmonary stenosis.
