Outpatient hysterectomy: determinants of discharge and rehospitalization in 133 patients

OBJECTIVE: This study examines our continuing experience in performing vaginal hysterectomies and laparoscopy-assisted vaginal hysterectomies with an outpatient protocol. The purpose was to review factors associated with discharge and hospitalization. STUDY DESIGN: Surgical records from all women entering our previously reported outpatient hysterectomy protocol were reviewed. Demographics, surgical indications, intraoperative data, and postoperative data were studied, and their associations with patient discharge and hospitalization were determined. Specific attention was directed to complications. RESULTS: The study group consisted of 133 women. Twelve women (9.0%) were not discharged from the hospital and 5 (3.8%) required readmission. Surgical indications, the type of hysterectomy, and the requirement for pain medication revealed no association with hospitalization. The occurrence of an intraoperative complication (p < 0.000), the need for transfusion (p = 0.043), and postoperative antiemetics (p = 0.013) were statistically associated with hospitalization. In addition, low hematocrit values and elevated temperatures on the first and second postoperative days were associated with hospitalization. CONCLUSION: Long-term experience with outpatient hysterectomy reveals a hospitalization rate of 12.8%. Complications, blood loss, elevated temperatures, and postoperative nausea are the major determinants of patient discharge and hospitalization. Readmission rates continue to remain low.     

Normal pregnancy and delivery following total hip joint replacement

Total joint replacement procedures should be restricted to older individuals or persons with limited physical activities or life expectancy. However, on occasion a total joint replacement may be the only means to avoid serious disability in a young, otherwise healthy individual. This report of a 19-year-old woman who underwent a total hip joint replacement following unsuccessful treatment of a severely comminuted intracapsular hip fracture. Subsequent to the total hip joint replacement the patient experienced a normal pregnancy and delivery.     

Cooperative study on the radioimmunological thyrotropin determination (hTSH) in serum (author''s transl)

The increased incidence of drowsiness in hypoalbuminemic patients administered diazepam and more rapid clearance of tolbutamide in cirrhotics may be due to changes in plasma protein binding. The binding of diazepam and tolbutamide was studied by equilibrium dialysis at 37degreesC over a total drug concentration range of 1 to 10 mug/ml and 50 to 300 mug/ml, respectively, in plasma from 21 normal and 14 alcoholic subjects. At 1 mug/ml, diazepam plasma protein binding (+/- S.D.) was 98.5+/-0.4 per cent in normals and 97.8+/-1.2 per cent in alcoholics; at 100 mug/ml, tolbutamide binding was 97.8+/-0.3 per cent in normals and 95.1+/-4.2 per cent in alcoholics. For both agents at all concentrations, the binding to plasma from alcoholics was significantly decreased (P less than 0.01-less than 0.02). The extent of binding of both drugs was dependent on the albumin concentration. These findings suggest that important changes in pharmacologic effect, distribution, and clearance of diazepam and tolbutamide can be anticipated in alcoholics with hypoalbuminemia.     

Basic laparoscopic knowledge among gynecologic laparoscopists

OBJECTIVE: Our purpose was to assess the basic knowledge of laparoscopy and laparoscopic sterilization among gynecologic laparoscopists. STUDY DESIGN: A four-part multiple-choice test designed for use in residency training, covering basic aspects of laparoscopy and laparoscopic sterilization, was distributed to 155 registrants at a gynecologic surgery postgraduate course. Test results were compared among subgroups, as well as with results for 23 residents who had taken the test before their rotation in laparoscopic sterilization. RESULTS: Residents scored higher than practitioners on all test segments. No practitioner achieved the 85% correct passing score required of residents. Practitioner scores did not increase as the number of laparoscopic sterilizations performed per year increased, but higher test scores were associated with more recent completion of residency. CONCLUSION: Basic knowledge of laparoscopic sterilization among practicing gynecologists, as measured by a test designed for residents, is less than that of the residents.     

Public health risks of ostrich and crocodile meat

This paper discusses the infectious agents and chemical substances potentially capable of contaminating the meat of ostriches and crocodiles and which thus pose a danger to human handlers and consumers. For ostrich meat, there is no danger from Crimean-Congo haemorrhagic fever or spongiform encephalopathy. Contamination of ostrich meat with salmonellae, chlamydia, pasteurellae, mycobacteria and erysipelas might be possible, but has never been reported. No parasites are known which could be transmitted through ostrich meat to human consumers. Residues from growth hormones, antibiotics and acaricides are potential public health hazards. For crocodile meat, there is a distinct possibility of contamination with salmonellae, depending on housing, feed, slaughter technique and hygiene practices under which the animal is reared. Chlamydial infections are common on some crocodile farms in southern Africa. Mycobacteriosis is extremely rare. Tapeworm cysts have been found in crocodile meat in two cases only. Trichinellosis has been reported on several crocodile farms in Zimbabwe. A generalised coccidiosis with invasion of organs and tissues has been seen in several species of crocodiles, but should present no danger to consumers.     

Resynchronisation of a diurnal rodent circadian clock accelerated by a melatonin agonist

Using 'jet lag' paradigms involving phase shifts in the light-dark (LD) cycle, we studied the effects of S-20098 on the circadian clock of a diurnal rodent. Arvicanthis mordax, entrained to a regular LD cycle, were subjected to advance shifts (i.e. 4, 6 or 8 h) in the LD cycle and injected with vehicle or the melatonin agonist S-20098 (20 mg/kg) the day of the shift (and also on subsequent days in the 6 h or 8 h shift paradigms). In each condition, S-20098 accelerated by about 30% resynchronization to the new LD cycle. These data, which are the first to demonstrate the chronobiotic effects of a melatonin agonist in a diurnal rodent, provide new insights for the design of human chronopharmacological protocols.
