The relationship between lichen planus and hepatitis C in dermatology outpatients in Kerman, Iran

BACKGROUND: Lichen planus (LP) is classified as a papulosquamous disease. It has been associated with liver disease, particularly hepatitis C virus (HCV) infection, in several studies. Most of these reports, especially the larger series, were conducted in Europe and Japan. OBJECTIVE: We conducted a case-control study in Kerman, Iran to explore the association between LP and HCV. METHODS: The study included 66 patients with LP (as cases; mean age = 39.7 +/- 15.8 years; 31 female, 35 male) and 140 volunteer blood donors (as controls; mean age = 29.5 +/- 8.4 years; 43 females, 97 males). An enzyme-linked immunosorbent assay (ELISA) was used to determine the presence of anti-HCV antibodies in all subjects in both groups. To confirm positive diagnoses, a second generation recombinant immunoblot assay (RIBA II) test was performed. RESULTS: Lichen planus lesions were most frequently located on the trunk and extremities, and the most common clinical type was generalized LP (48.5%). One of the patients with LP (1.5%) and three of the controls (2.1%) were HCV-Ab positive. No significant difference was observed in HCV-Ab positive between the two groups (OR = 0.7; 95% CI = 0.1-6.9). CONCLUSION: The findings indicate that an investigation for HCV infection should not necessarily be performed in all patients with LP. It is recommended that further studies should focus on larger groups in other regions of Iran to determine whether testing for HCV infection is necessary in patients with LP.     

Concentrated pomegranate juice improves lipid profiles in diabetic patients with hyperlipidemia

This study assessed the effect of concentrated pomegranate juice (CPJ) consumption on lipid profiles of type II diabetic patients with hyperlipidemia (cholesterol >/= 5.2 mmol/L or triacylglycerol >/= 2.3 mmol/L). In this quasi-experimental study 22 otherwise healthy diabetic patients, 14 women (63.6%) and eight men (36.4%), were recruited from among patients referred to the Iranian Diabetes Society. The patients were followed for 8 weeks to establish a baseline for normal dietary intake before beginning the CPJ intervention. During the pre-study period a 24-hour food recall and food records (recording flavonoid-rich foods) were completed every 10 days. At the end of the eighth week, anthropometric and biochemical assessments were done. Thereafter the patients consumed 40 g/day of CPJ for 8 weeks, during which time dietary assessment was continued. After completing the study, anthropometric and blood indices were again evaluated. The Wilcoxon signed test was used for statistical analysis. A value of P <.05 was considered significant. Mean (+/-SD) age, weight, and duration of diabetes were 52.5 +/- 5.2 years, 71.5 +/- 10.3 kg, and 7.9 +/- 6.6 years, respectively. After consumption of CPJ, significant reductions were seen in total cholesterol (P <.006), low-density lipoprotein (LDL)-cholesterol (P <.006), LDL-cholesterol/high-density lipoprotein (HDL)-cholesterol (P <.001), and total cholesterol/HDL-cholesterol (P <.001). But, there were no significant changes in serum triacylglycerol and HDL-cholesterol concentrations. Anthropometric indices, physical activity, kind and doses of oral hypoglycemic agents, and the intakes of nutrients and flavonoid-rich foods showed no change during the CPJ consumption period. It is concluded that CPJ consumption may modify heart disease risk factors in hyperlipidemic patients, and its inclusion therefore in their diets may be beneficial.     

杜安眼球后退综合征和染色体组异常

目的:观察I型杜安眼球后退综合征患者的第8染色体。方法:连续观测了29例I型杜安眼球后退综合征患者的第8染色体。采用质粒DNA提取试剂盒方法从患者的外周血白细胞里分离提取DNA,选取D8S553和D8S1797做标记,用PCR法进行测定。结果:实验的所有病人样本中没有D8S553和D8S1797标记阳性。结论:我们的发现提示所观察的I型杜安眼球后退综合征患者的可能病因是属散发病例而没有家族史,建议纳入更多病例、选取其他的标记和不同的染色体进行进一步的研究。     

Bone density in patients with chondromalacia patella

Chondromalacia of the patella is the most common cause of anterior knee pain in young women. The etiology of the disease is not well-understood but the initial lesion is a disorganization of collagenous structures. Since the disease is proposed to be due to generalized constitutional disturbance, we postulated that bony structures could also be involved. To investigate this hypothesis we measured the bone density of 286 patients with the diagnosis of chondromalacia of the patella during a 4-year period using dual energy X-ray absorptiometry (DXA) method. We found a significant number of patients having low bone densities. This problem was more pronounced in men and in younger age groups. We suggest base-line bone density evaluation in all patients, treatment of osteopenia or osteoporosis in select patients and regular follow-ups using DXA.     

The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30): translation and validation study of the Iranian version

The objective of this study was to test the reliability and validity of the Iranian version of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30). The English-language version of the questionnaire was translated into Persian (Iranian language), and its final form was approved by the EORTC Study Group on Quality of Life before it was used in this study. The questionnaire was administered at two time points to a consecutive sample of 168 newly diagnosed breast cancer patients, and almost all of them (99%) found the questions easy to understand and acceptable. Crohnbach's alpha coefficient for multi-item scales (to test reliability) ranged from 0.48 to 0.95 at baseline and from 0.52 to 0.98 at follow-up administration of the questionnaire. Validity was checked using two methods: inter-scale correlation and known-groups comparison. Almost all inter-scale correlations were statistically significant in the expected direction. Known-groups comparison analysis showed that all functioning and symptom scales discriminated between subgroups of patients differing in clinical status as defined by their performance status and disease stage. In general, the findings of this study indicate that the Iranian version of the EORTC QLQ-C30 is a reliable and valid measure of quality of life in cancer patients and can be used in clinical trials and studies of outcome research in oncology.
