Outcomes of resection for rectal cancer in India: The impact of the double stapling technique

BACKGROUND: The introduction of circular staplers into colorectal surgery has revolutionized anastomotic techniques stretching the limits of sphincter preservation. Data on the double-stapling technique (DST) has been widely published in the West where the incidence of colorectal cancer is high. However studies using this technique and their results, in the Indian scenario, as well as the rest of Asia, have been few and far between. AIM: To evaluate the feasibility of the DST in Indian patients with low rectal cancers and assess its impact on anastomotic leak rates, covering colostomy rates, level of resection and morbidity in patients undergoing low anterior resection (LAR). METHODS: A comparative analysis was performed between retrospectively acquired data on 78 patients (mean age 53.2 ± 13.5 years) undergoing LAR with the single-stapling technique (SST) (between January 1999 and December 2001) and prospective data acquired on 138 LARs (mean age 50.3 ± 13.9 years) performed using the DST (between January 2003 – December 2005). RESULTS: A total of 77 out of 78 patients in the SST group had Astler Coller B and C disease while the number was 132/138 in the DST group. The mean distance of the tumor from anal verge was 7.6 cm (2.5–15 cm) and 8.0 cm (4–15 cm) in the DST and SST groups, respectively. In the DST group, there were 5 (3.6%) anastomotic failures and 62 (45%) covering stomas compared to 7 (8.9%) anastomotic failures and 51 (65.4%) covering stomas in the SST group. The anastomotic leak rate, though objectively lower in the DST group, did not attain statistical significance (p = 0.12). Covering stoma rates were significantly lower in DST group (p = 0.006). There was 1 death in the DST group due to cardiac causes (unrelated to the anastomosis) and no mortality in the SST group. The LAR and abdominoperineal resection (APR) rates were 40% and 60%, respectively, during 1999–2001. In 2005, these rates were 55% and 45%, respectively. CONCLUSION: This study, perhaps the first from India, demonstrates the feasibility of the DST in a country where the incidence of colorectal cancer is increasing. Since the age at presentation is at least a decade younger than the Western world, consideration of sphincter preservation assumes greater significance. The observed improvement of surgical outcomes with DST needs further studies to significantly prove these findings in a population where the tumors at presentation are predominantly Astler Coller Stage B and C

Armodafinil versus Modafinil in Patients of Excessive Sleepiness Associated with Shift Work Sleep Disorder: A Randomized Double Blind Multicentric Clinical Trial

Aim. To compare the efficacy and safety of armodafinil, the R-enantiomer of modafinil, with modafinil in patients of shift work sleep disorder (SWSD). Material and Methods. This was a 12-week, randomized, comparative, double-blind, multicentric, parallel-group study in 211 patients of SWSD, receiving armodafinil (150 mg) or modafinil (200 mg) one hour prior to the night shift. Outcome Measures. Efficacy was assessed by change in stanford sleepiness score (SSS) by at least 2 grades (responder) and global assessment for efficacy. Safety was assessed by incidence of adverse events, change in laboratory parameters, ECG, and global assessment of tolerability. Results. Both modafinil and armodafinil significantly improved sleepiness mean grades as compared to baseline (P < .0001). Responder rates with armodafinil (72.12%) and modafinil (74.29%) were comparable (P = .76). Adverse event incidences were comparable. Conclusion. Armodafinil was found to be safe and effective in the treatment of SWSD in Indian patients. The study did not demonstrate any difference in efficacy and safety of armodafinil 150 mg and modafinil 200 mg

Periodic Research Influence of Intercropping, Weed Control and Fertility Management Practices on Stalk Yield, Biological Yield and Harvest Index of Cotton

Keywords: Biological yield, fertility management, harvest index, intercropping, stalk yield and weed control etc. Introduction Intercropping is most common practice in long duration rainfed cotton crop as a risk covering factor. The assumption is that the growing of different intercrops like pulses, oilseed, vegetable, flowers etc. having characters of short duration, non competitive, less input user, ability of suppressing weeds, exploit better environment and resources to fulfill the nutritional requirement of main crop and give the additional yield and return. Therefore, the interest of farmers is rapidly growing in diversified intercropping to maximize production. There is need to adopt profitable and resource efficient cropping system along with weed control and fertilizer management practices which gives higher returns than existing cropping system. Keeping in view, the maintenance of natural resources optimally and effectively in conservative way to sustain productivity this investigation was undertaken. Materials and Methods Tw

Primary cutaneous nocardiosis

A 35-year-old male presented with multiple discharging sinuses and fluctuant swelling on right side of face which started after a vehicular accident three year back. The lesions did not respond to routine antibiotics treatment but went on increasing. Gram smear showed typical acid fast branching filaments suggestive of nocardiosis, which was confirmed by culture. Patient received co-trimoxazole for three and a half month. When seen again after three years, all the lesions had healed with puckered scarring. Patient had received co-trimoxazole for three and a half months with dramatic improvement

Comparative study of calcipotriol ointment and mometasone furoate ointment in patients of psoriasis vulgaris: A double blind study

Introduction: Psoriasis is a chronic, inflammatory papulosquamous disease clinically characterized by erythematous, sharply demarcated, indurated papules and rounded plaques covered by silvery, micaceous scales. Psoriasis is characterized by hyperproliferation and abnormal differentiation of epidermal keratinocytes, infiltration of mostly T lymphocytes and various endothelial vascular changes in the dermal layer, such as angiogenesis, dilatation and high endothelial venule (HEV) formation. Material and Methods: The study was conducted on 70 patients of psoriasis attending the outpatient department. Patients who fulfilled the selection criterion were alternately assigned into two groups, 35 patients in each group. The assessment of effectiveness was done with the help of PASI. Follow up of patients were done after 1st, 2nd, 4th and 6th week of initiation of treatment. Results: We observed 70 patients and both the group showed statistically significant reduction in the disease severity. Conclusion: The calcipotriol and mometasone furoate ointment were found to be equally effective in clearance of the disease
