Efficacy of viable BCG vaccine paste in the treatment of common warts: a double-blind randomized control trial

Background Treatment of common warts may be painful or leaves scars, mainly using traditional destructive methods. This study aimed to evaluate the efficacy of the viable Bacillus Calmette‐Guérin (BCG) vaccine in paste formula as an immunotherapeutic modality for common warts treatment. Methods This double-blind and randomized, parallel-group, placebo-controlled trial was conducted at the Ahvaz Imam Hospital Dermatology Department from November 2014 to 2015. Overall 80 patients with common warts in two groups (case and control) received BCG vaccine paste once weekly for eight consecutive weeks. Follow-up was done every two weeks during treatment and six months after the treatment to evaluate recurrence in patients with complete resolution. Results In group A, eight patients (20%) had a complete response, 15 patients (37.5%) partial response, four patients (10%) low response, and 13 patients (32.5%) no response (p < .001). All patients in group B had no response to treatment (p < .001). After six months of follow-up, no recurrence was seen. Duration of disease less than 12 months (p = .001) and the number of lesions less than three (p = .01) were determining factors of response to treatment. Conclusion Topical BCG vaccine paste was an effective treatment for common warts, without recurrence and significant complications

Evaluation of the frequency of ABO and Rh-Hr blood-group systems in different acquired cataracts type

Abstract Objectives This study evaluated the relationship between acquired cataract’s different types and the ABO and Rh blood classes. Methods Overall, 520 patients, by randomized sampling method, participated in this retrospective cross-sectional study. After reviewing the patient’s medical records and laboratory results, the patient’s demographics, ABO group, Rh, and cataract type were documented. Results A total of 520 patients were included in the research, with a mean age of 67.57 ± 11.85. Most of them were female (n = 286, 55%). Mix (n = 230, 44%) and nuclear sclerotic (NS) (n = 167, 32%) cataracts were the most common types. The posterior subcapsular cataract (PSC) prevalence in females was significantly higher than in males (16.1% vs.7.3% p = 0.002). Also, men had more NS cataracts than females (89, 38% vs. 78, 27.3%) (p = 0.009). Patients with PSC were significantly younger than others (all p-values  0.05). Conclusion Although our findings showed that cataract types are independent of blood group types and Rh, they can be compared with future studies on the association of other Blood-Group Systems in developing acquired cataracts
