Comparison of internal sphincterotomy with topical diltiazem for post-hemorrhoidectomy pain relief: a prospective randomized trial.

AIM: To assess the efficacy of internal sphincterotomy compared with application of topical 2% Diltiazem ointment after hemorrhoidectomy for pain relief. SETTINGS AND DESIGN: Prospective randomized study. MATERIALS AND METHODS: In an 18-month period, 108 subjects with uncomplicated Grade 3/ 4 hemorrhoids were enrolled in the study and were randomized into two equal groups: Subjects in Group A underwent internal sphincterotomy at time of primary surgery while those in Group B received 1 g of 2% Diltiazem ointment locally, thrice daily for seven days. Postoperative pain perception was measured using visual analog score (VAS) and on the basis of number of analgesic tablets (Tab tramadol 50 mg) required in each group. Time to discharge, time to return to work and incidence of complications measured and compared. STATISTICAL ANALYSIS USED: Statistical techniques applied were Student T test, Chi-square and Fisher's Exact Test. RESULTS: There were 102 analyzable subjects (Group A: 50 and Group B: 52). The mean VAS score was significantly less in the internal sphincterotomy group from the fourth postoperative day onwards compared to topical Diltiazem (2.23 vs. 3.72; P =0.031). Similarly, the mean requirement of analgesic tablets [10.54 vs. 15.40; P =0.01] was much lower in Group A. There was no significant difference in terms of time to discharge and time to return to work between the two groups. The incidence of complications was more with the internal sphincterotomy group (11.5% vs. 3 %; P =0.488). CONCLUSIONS: In patients undergoing hemorrhoidectomy, addition of surgical internal sphincterotomy results in lesser pain in the postoperative period as compared to those receiving topical application of Diltiazem.

Deaths due to rapid high altitude climbing (ASCEND).

High altitude pulmonary edema develops in people who make a rapid ascend to a high altitude and the body is not able to acclimatize itself. We came across two such cases in the department of Forensic Medicine at I.G.M.C, Shimla.

Testicular toxicity in rat to repeated oral administration of tetramethylthiuram disulfide (Thiram).

Thiram was administered to male rats through gavage at doses 5, 10 and 25 mg/kg/day for 180 and 360 days. Thiram has caused marginal increase in the relative weight of testes and epididymis and decrease in the weight of seminal vesicle and prostate. Marked degenerative changes were observed in seminiferous tubules together with alterations in testicular enzyme profile. The activity of testicular enzymes such as ACP, SDH and ATPase (Na+ + K+ dependent) was decreased whereas activity of LDH, G-6-PDH and ALP increased. The levels of serum cholesterol and testicular free sialic acid were enhanced, while the level of testicular protein was lowered. It is evident from the present study that long term treatment of thiram at tested dose levels has resulted in dose and time dependent morphological and biochemical changes in testes of rat.

99m Tc DTPA scan as a diagnostic marker of acute rejection in renal transplantation.

Forty renal transplant recipients were subjected to 99m Technicium Diethylene triamine pentacetic acid (DTPA)scans at regular intervals & whenever there was suspection of rejection. Serial scans of a group of 15 recipients from immediate post transplant period till withdrawal of cyclosporine were analysed separately & the results compared to with single scan analysis. The sensitivity & specificity of DTPA scan in the absence of acute tubular necrosis (ATN) was 94.1% & 87.5%, while the positive & negative predictive values were 88.8 & 93.3% respectively. Sensitivity & specificity of serial scan analysis (88.8% and 75%) in early post transplant period was higher than that of interpretation of single scan (75% & 66%). Serial scan changes predated clinical rejection during cyclosporine withdrawal period. We conclude that DTPA scan is both a sensitive & specific non-invasive diagnostic marker of acute rejection in absence of ATN & serial scans during early post transplant period & at the time of cyclosporine withdrawal are helpful in detecting the rejection accurately & at the earliest.

Significance of serum immunoglobulin levels in conglomeration with trans-sternal phlebography in the phlebography management of breast cancer.

The study was conducted on 63 patients with breast lump and twenty normal healthy females. In benign breast disease, a significant (P < 0.001) rise in serum IgA, significant (P < 0.001) decrease in IgG and no change in IgM levels was seen before operation. A significant decrease (P < 0.001) in serum IgA and significant increase in IgG and IgM was observed post operatively. In carcinoma breast, a significant (P < 0.001) elevation in IgA, IgG and IgM levels was found pre-operatively with a concomitant decrease in serum IgA and IgG and increase in serum IgM levels, post operatively. Trans-sternal phlebography (TSP) carried out with 95.23% success has revealed significant (P < 0.001) change in the staging of carcinoma breast. The increased levels of serum immunoglobulins associated with the patients of carcinoma breast with metastasis has led to conclude that these levels, if punctuated with TSP findings can lead to better assessment of the staging of carcinoma breast and thereby its management.
