Neurophysiological investigation of diabetic impotence. Are sacral response studies of value?

The role of electrophysiologically elicited sacral responses in the detection of the neurological component of diabetic impotence has been evaluated in a detailed study using properly defined diagnostic criteria. The results prove that these tests are not reliable indicators of neuropathy and their relevance in the routine investigation of diabetic impotence is of questionable value.     

The relevance of a staging laparotomy for Hodgkin's disease in India.

A retrospective analysis of 328 cases of Hodgkin's Disease (HD) subjected to a staging laparotomy at the Tata Memorial Hospital, Bombay, India, from 1974 to 1986 was undertaken to assess its relevance to our setup. Eighty percent of the patients were from clinical stages (CS) I and II, 38% with lymphocyte predominance (LP), and 41% with mixed cellularity (MC) histologies. Staging laparotomy was positive in 60% cases overall, including 50% from CS IA and IIA, 68% from CS IB and IIB, and 53% and 67%, respectively, from LP and MC histologies. Splenic involvement was seen in 54% cases. Operative complications were encountered in 2% of cases and deaths in two cases only. In view of the high propensity for abdominal spread, only selected CS IA and IIA cases would merit a staging laparotomy within which, nearly 50% cases with a negative yield could be offered radical segmental irradiation alone for cure. The majority of our patients would, however, require combination therapy.     

Experience with the International League Against Epilepsy Classifications of Epileptic Seizures (1981) and Epilepsies and Epileptic Syndrome (1989) in Epileptic Children in a Developing Country

Four hundred eighty-three epileptic children attending the Pediatric Epilepsy Clinic at Bai Jerbai Wadia Hospital for Children, Bombay, India were classified according to the International League Against Epilepsy (ILAE) classification of epileptic seizures (1981) and epilepsies and epileptic syndromes (1989). The predominant seizures were partial (53.6), generalized (40.3%), and unclassifiable (6%). In epilepsies and epileptic syndromes, 55.3% were partial, 27% were generalized, 13.5% were undetermined, and 4.1% were special syndromes. Although our results were similar in many respects to those of other reported series, some differences were observed in the incidence of partial and generalized seizures, and partial and generalized epileptic syndromes and their subgroups, such as idiopathic, symptomatic, and cryptogenic partial syndromes, idiopathic generalized syndromes, and symptomatic specific syndromes. These differences are probably due to different age limits, methods of case ascertainment and inclusion criteria, different genetic and environmental factors, variable interpretation of clinical and EEG features, and lack of facilities for investigation in developing countries. Despite various limitations, we were able to classify most cases; the ILAE classification can be used in developing countries so that comparison can be made with other studies.     

Bleeding complications associated with peritoneal dialysis catheter insertion.

OBJECTIVE: To identify the incidence of bleeding complications associated with peritoneal dialysis catheter insertion. DESIGN: Retrospective review at a tertiary-care center of all double-cuffed Tenckhoff catheters placed surgically from 1 January 1992 to 1 October 2003 to identify the incidence of major bleeding complications occurring with catheter insertion. Major bleeding episodes were defined as > or = 3% decline in hematocrit, or the need for surgical intervention or blood transfusion within 2 weeks of insertion. RESULTS: 292 catheters had been inserted in 263 patients. Six patients satisfied the criteria for a major bleeding event, for a major bleeding complication rate of 2%. Bleeding was associated with perioperative anticoagulation in 3 patients, uremia and thrombocytopenia in 1 patient, aspirin use and thrombocytopenia in 1 patient, and 1 patient experienced intraoperative bleeding. Coagulation parameters were not obtained prior to the procedure in 2 of the 6 patients. CONCLUSION: The rate of serious bleeding complications related to catheter insertion is low and usually associated with anticoagulation. Holding anticoagulation therapy for a minimum of 24 hours during the postoperative period should eliminate much of the risk. Coagulation parameters should also be obtained and corrected preoperatively.     

Biochemical changes in the liver of fish, Tilapia mossambica (Peters), during continuous exposure to monocrotophos

The purpose of the present investigation was to determine the effect of continuous exposure to the organophosphate monocrotophos at 2.5 ppm for over a period of 2 through 45 days on protein, RNA, and DNA contents and on 5'-nucleotidase activity in the liver of Tilapia mossambica. Protein content was decreased by 45% after 5 days, returned to control levels at 10-30 days, and again decreased by 45 days. DNA content was decreased by 2 days, returned to control values by 5 days, and remained constant throughout the exposure. In contrast, RNA content was significantly lower starting from 2 through 45 days of exposure. 5'-Nucleotidase activity showed a transient increase at 5 and 30 days of monocrotophos exposure. These results indicate that monocrotophos altered the protein, DNA, and RNA contents and the 5'-nucleotidase activity levels as early as 2 and 5 days. However, these changes were reversed by 10 days and after a short period of recovery, the alterations reappeared. This supports our earlier histological observations of hepatic pathology during monocrotophos exposure.     

Epiphrenic diverticulum of the esophagus.

Esophageal diverticula are rarely found at the terminal portion, where they are called supradiaphragmatic or epiphrenic diverticula and occur in association with motility disorders of the terminal esophagus. We present here two cases of epiphrenic esophageal diverticulum, one of which was treated surgically.     

Conservative treatment of scald burns is superior to early excision.

Early excision of deep burns has been advocated; however, it is difficult to clinically determine the depth of scald burns during the early postburn period. This prospective, randomized study was designed to determine whether early excision was superior to conservative treatment of scald injuries. Patients with scald injuries (which were not caused by grease) of clinically indeterminant depth were randomized to early (n = 12) or late (n = 12) excision; all patients with obvious superficial and full-thickness injuries were excluded. In the early excision group, all deep wounds were tangentially excised and grafted within 72 hours of admission, whereas in the late treatment group wounds were excised and grafted after 2 weeks had passed since injury. Area excised, postburn day of excision, percent graft take, operating-room time, blood replacement, incidence of infection, and length of hospital stay were compared. No patient experienced a significant wound infection or systemic sepsis. A significantly smaller area of excision was necessary for those patients who were treated with delayed surgery, and concomitant decreases in operating-room time and blood loss were observed. Notably, only one half of the patients who were randomized to the delayed excision group ultimately required surgical intervention to achieve wound closure. Graft take was comparable for both groups, as was length of hospital stay. Early clinical evaluation of scald injuries appears to be equivocal, and later evaluations reveal a less severe injury. Financial gains can be made when surgical excision of scald injuries is delayed until 2 weeks after injury because of a related reduction in hospital expenditures.
