Evidence For Casual Household Transmission Of Hiv: Review And Analysis

School of Education, Bar-Ilan University, Ramat-Gan

All reported case-studies in which the author-described route of infection was deemed to be casual household contact were reviewed and analyzed, as well as all sample-based studies designed to estimate the frequency of casual household transmission. Several recurring biased mechanisms of interpretation were found in the studies, the use of which made it impossible to obtain evidence for casual household transmission. After correcting for these interpretations 8 documented cases of casual household transmission were found. Analysis of the sample-based studies indicated 10 cases of casual household transmission, which occurs at a risk of 0.4% per year of contact (95% confidence interval: 0.20 to 0.66).

Managing anesthesia care for separation of conjoined twins poses a special challenge for the anesthesia team. Early preparation, thorough understanding of the anatomical and the physiological consequences of this complex anomaly, as well as careful coordination with the teams of surgeons, nurses and operating room personnel are mandatory to assure successful separation of the conjoined twins. It is recommended that the mother be transferred to and the babies be delivered at a tertiary care medical center, like the Children's Hospital. Special attention is devoted during the surgical procedure to cardiovascular stability, drug disposition, fluid balance and temperature control. The multidisciplinary team approach makes this complex surgery a success. When postoperative survival cannot be guaranteed for both twins, close contact and consultation is mandated with the parents, medical personnel and religious and legal advisors.

The visual outcome in 23 men and 2 women with traumatic cataracts was analyzed retrospectively. Their average age was 33 and they ranged from 10 to 69 years. Surgical results were either very good or very poor. Associated retinal injuries significantly decreased final visual acuity (p = 0.001). Those with initial visual acuity restricted to finger counting had better visual results than those with initial visual acuity restricted to light perception (p = 0.01) and hand motions (p = 0.02). Usually the lens was removed via the pars plana; the most common mode of optical correction was contact lenses.

Volume reduction surgery (VRS) is a new procedure based on the concept that relieving hyperinflation in emphysema improves diaphragmatic and chest wall mechanics and ventilation perfusion mismatch. We present our early experience with 16 patients who underwent VRS from August 1995 to June 1996. Patient selection was based on: PFT, CT scan, V/Q scan, ABG's and 6-min walk. After pulmonary rehabilitation, operation was by median sternotomy and bilateral lung shaving. Pulmonary function improved significantly. FEV1 increased from 0.68 ± 0.2 to 1.0 ± 0.2 L (p<0.01) and FVC increased from 1.7 ± 0.5 to 2.7 ± 0.5 L (p<0.017). Total lung capacity decreased from 129% ± 24% to 108% ± 20% (p<0.03). 6-min walk increased from 221 ± 90 to 404 ± 123 meters (p<0.001). Complications included 1 death, prolonged air leak in 7 cases and infection in 2. Quality of life improved substantially in 12 of the 16 cases; in 3 cases there was only slight improvement and in 1 the condition became worse. Volume reduction surgery is a promising surgical solution in selected patients with advanced emphysema.
