ABSTRACT
This study aimed at assessing the expression rate of IgA and IgM in B cell lymphoma immunohistochemically. Paraffin-embedded specimens of NHL evaluated for presence of CD20 by immunohistochemical staining and then, the positive cases were again immunohistochemically assessed for expression of IgM and IgA. Fifty two paraffin-embedded specimens evaluated. Thirty six cases (69.2%) were positive for the CD20. The mean age of these patients (CD20+ cases) was 50.0 +/- 23.6 years. Twenty two cases (61%) were male and 14 cases (39%) were female. The frequency of the IgM+, IgA+ and IgA/IgM+ (simultaneous) cases was 15 (41.7%), 9 (25%) and 4 (11.1%), respectively. The current rates are in the range of similar reports in the literature.

INTRODUCTION: Ramadan is the holiest month in the Islamic calendar and Muslims fast during this month. We designed this study to evaluate the effect of Ramadan fasting on plasma lipids and lipoproteins. METHODS: This cohort study was performed during Ramadan in December 2002 (Islamic year 1423). The subjects were 81 students of Tehran University of Medical Sciences. We evaluated weight, body mass index (BMI), glucose, triglyceride (TG), cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), and very low density lipoprotein (VLDL), before and after Ramadan. RESULTS: Body weight and BMI both decreased during Ramadan fasting in both genders. Glucose and HDL decreased and LDL increased significantly during fasting in Ramadan, but there was no significant change in total cholesterol, TG and VLDL. We did not find any association between TG, cholesterol, LDL, VLDL, HDL and the following variables: sex, body weight changes, and two or three instances of meals before Ramadan. Triglyceride level also increased in students with normal BMI while it decreased in overweight subjects. CONCLUSION: This study indicated that Ramadan fasting led to a decrease in glucose and weight. Although there was a significant reduction in meal frequency, a significant increase in LDL and decrease in HDL was noted during Ramadan. It seems that the effect of Ramadan fasting on serum lipid levels may be closely related to the nutritional diet or biochemical response to starvation.

Demonstration of functioning heterotopic gastric mucosa with 99mTc-pertechnetate SPECT is reported. Abnormal tracer uptake was shown conclusively with SPECT but not with planar imaging. When a Meckel's diverticulum is suspected, we suggest SPECT be performed if the results of planar scintigraphy are equivocal and that it be considered if there is a high clinical suspicion and planar imaging is normal.

Ectopic insertion of a ureter draining a hypoplastic dysplastic kidney is a significant cause of urinary incontinence in girls. In this case, such a kidney was detected with 99mTc-DMSA scintigraphy but not by intravenous pyelography. Scintigraphy facilitated further delineation of the anatomy with CT prior to nephrectomy. Based on this case and a literature review, we suggest that 99mTc-DMSA scintigraphy be performed early when evaluating girls with urinary incontinence.
