DAY-ONLY ADMISSION FOR VARICOSE VEIN SURGERY

Day-only admissions for surgery are strongly encouraged, in an effort to keep costs down. Varicose vein surgery has been considered too major for day-only management despite the fact that there have been studies from overseas showing that it can be done with a morbidity comparable to inpatient surgery. The morbidity of day-only surgery for varicose veins (both long and short saphenous procedures) was assessed and compared with the results of inpatient surgery. Patients were also asked whether they were satisfied with the surgery being done this way. There were 165 consecutive patients available for study, 64 day-only and 101 inpatient. All patients attending Shellharbour Hospital, Shellharbour, had surgery done as day-only (as it was a morning list and allowed adequate time for recovery). Patients attending Bulli Hospital, Bulli, had surgery done as an inpatient (afternoon list). All surgery was performed by one surgeon. There was no difference (Chi-squared) in the age distribution (mean 48 years for day-only, 51 years for inpatient) or sex proportion in either group (Chi-squared test of proportions with continuity correction). Assessment of the results was done by review of the surgeon's notes, as well as telephone interviews for day-only subjects. The complication rate in both groups was similar. Wound problems represented the main complication with an incidence of 10.5% in each group. There was one deep venous thrombosis (DVT) in each group (diagnosed by duplex scan). Response to the telephone interview suggested that most patients were happy to have the surgery done as a day-only procedure. Sixty-nine per cent responded that they would have it done this way again and 76% were satisfied with the result of the surgery. This study confirms the results of overseas studies, in that varicose vein surgery can be performed as day-only procedures with a complication rate similar to inpatient procedures and with a high degree of patient satisfaction. It is suggested that this should be used as the method of choice for the majority of patients requiring varicose vein surgery.     

Evaluation of postsurgical crestal bone levels adjacent to non‐submerged dental implants

In most of the studies on long-term radiographic evaluations of crestal bone levels adjacent to dental implants, no baseline radiographs taken immediately post-surgically had been obtained.The aim of this study was to test the reproducibility of a simple radiographic method for linear measurements of changes in bone levels and to evaluate changes in crestal bone levels adjacent co non-submerged ITI® implants 1 year following the surgical procedure. From 128 patients enrolled in a clinical and radiographic longitudinal study 40 patients also had radiographs taken immediately postsurgically. They were, however, not obtained as “identical” images. The radiographs were mounted onto slides and projected on a screen. Mesially and distally from 57 implants triplicate linear measurements of the distance implant shoulder to bone crest were taken, using known dimensions of the implants as internal reference distances. The median difference of 213 (out of 228 possible) duplicate measurements was 0.00 mm (ranging from ?1.72 mm to +1.47 mm when comparing the second co the third reading). Some 81% of the double measurements were within ±0.5 mm and the precision was 0.30 mm. In the immediate postoperative radiographs the median mesial bone level was located at 2.07 mm (distally 2.19 mm) from the implant shoulder. A statistically significant amount of bone loss in the first year was observed mesially (median=?0.78 mm) and distally (0.85 mm)(Wilcoxon matched pairs signed rank test ±0.001). No statistically significant influence of the implant location, the implant length, type of the implant (screw; cylinder) was observed (Kruskal-Wallis P>0.05).The age of the patients was not correlated significantly to the amount of bone loss observed. In conclusion, methodological limitations existed when evaluating linear bone changes in non-identical radiographs using reference dimensions of the implants. The amount of postsurgical bone loss estimated in other studies was confirmed when using an immediate postoperative radiograph as a baseline.     

Hepatic resections for metastases]

Between January 1981 and December 1990, 79 liver resections were performed for hepatic metastases in 73 patients. Eight of these patients had a repeat resection (2 patients had their first resection performed before 1981). This figure represented 35% of 228 liver resections performed during this period. Mean age was 56.5 years (23 to 81 years). There were 38 men and 35 women. Fifty-four resections were performed for colorectal metastases and 25 resections for secondaries of other origins. There were 45 major hepatectomies (57%), defined by the resection of at least 3 Couinaud segments, and 34 minor resections (less than three segments). In 12 patients, liver resection was associated with excision of the primary tumor. Complications were observed in 25 patients (32%), pulmonary complications being the most frequent. Five re-explorations were necessary: 3 for postoperative bleeding, one for an abdominal abscess and one for intestinal obstruction. Mean postoperative stay was 18 days. There was no mortality for the first liver resections in 71 patients. One death was encountered among the second resections in 8 patients, with a global mortality of 1.3%. Follow-up was obtained for all patients but one (lost to follow-up at 5 years). Actuarial survival for the 50 patients operated on for colorectal secondaries was 98% at 6 months, 83% at 1 year, 46% at 2 years, 24% at 3 years and 15% at 5 years. In non-colorectal secondaries, the survival depended on the nature of the primary tumor but was very different from one patient to another.(ABSTRACT TRUNCATED AT 250 WORDS)     

Hypothyroidism and hyperprolactinemia as a possible cause of androgenetic alopecia in the female

31 female patients suffering from androgentic alopecia were examined by means of the TRH test with regard to hypothyroidism and hyperprolactinemia. Before, as well as 20 and 40 minutes after, application of thyroxine releasing hormone (TRH), the serum concentrations of the hypohyseal thyroxine stimulating hormone (TSH) and prolactin (PRL) were measured by radioimmunoassay (RIA). In 7 of the patients (23%), we found increased TSH levels after stimulation with TRH--indicative of hypothyroidism. In 9 of the patients (29%), we observed increased PRL levels after TRH stimulation, indicating prolactinemia. TSH and PRL can interact with androgen metabolism at various levels. Thyroxine may influence the unbound, metabolically active testosterone via the sex hormone binding globulin (SHBG). Prolactine, which is stimulated by TRH, promotes the suprarenal cortisol and androgen production. In 48% of the patients, we found either hypothyroidism or hyperprolactinemia. This suggests that both conditions may contribute to the clinical picture of female androgenetic alopecia, as they interfere with the androgen metabolism.     

A theory of family,economy, and gender

Historically, the requirements of population replacement have interacted with modes of subsistence technology to shape the differential distribution of power and prestige by sex. Two assumptions undergird Huber's argument: in all societies, producers have more power than consumers; those who control the distribution of valued goods beyond the family have the most power. Evidence comes from societies based on foraging, the hoe, the plow, herding, and industrial technologies. Huber concludes that changes in the work people do have altered the stratification and family systems of plow societies. Declines in mortality and fertility and changes in lactation customs have reduced the time that women spend pregnant or nursing. Increases in educational levels and employment rates enable women to provide sizable shares of family income. These trends have increased the centrality of individual goal attainment in the Western ideational system. Now women, along with men, have been swept into the occupational streams of the industrial revolution, though not quite into the mainstream. Still in question is the extent to which women will hold a fair share of top positions. This will hinge on responsibility for housework and childcare early in a woman's career, a time when most single parents or couples lack resources to command full-time quality care for the daily needs of their children. Ambitious women can avoid much conflict by remaining childless, but that is the point; ambitious men need not make that choice. Women cannot become men's social equals until the most talented women can aspire as realistically as their male counterparts to contribute in proportion to their talents. Thus, the overlap of family, economy, and gender, reshaped by continuing technological change, continues to affect women's status. Industrialization 1st turned the cost-benefit ratio of children upside down. Then wives were drawn into the labor force, raising the opportunity cost of their time, and thereby the cost of children. Now, below-replacement fertility in the West has highlighted the problem of population maintenance. Parenthood may have to be made more attractive by limiting the hours of responsibility. Such measures would be expensive but they would raise women's status in the family and in society in ways that were unimaginable a few decades ago.     

Reactivity of microhemagglutination, fluorescent treponemal antibody absorption, Venereal Disease Research Laboratory, and rapid plasma reagin tests in primary syphilis.

Seroreactivity of sera from 109 patients with first-infection primary syphilis was 98.2% in the fluorescent treponemal antibody absorption test, 92.7% in the rapid plasma reagin 18-mm circle card test, 72.5% in the microhemagglutination test (MHA-TP), and 72.5% in the Venereal Disease Research Laboratory test. Seroreactivity of sera from 18 patients with primary syphilis with documented previous infection(s) was 100% in the fluorescent treponemal antibody absorption test, the rapid plasma reagin 18-mm circle card test, and the MHA-TP test and 88.9% in the Venereal Disease Research Laboratory test. The MHA-TP test failed to confirm reactivity in 13 of 79 sera which were reactive in the Venereal Disease Research Laboratory test and in 24 of 101 sera which were reactive in the rapid plasma reagin 18-mm circle card test. Testing another production lot of MHA-TP reagents resulted in even poorer correlation. The reactivity of the MHA-TP test in primary syphilis appeared to vary with the sensitivity of the production lot of reagents.
