Drowning is a leading cause of accidental deaths worldwide, but its pathological diagnosis remains a challenge for forensic pathologists owing to a lack of pathognomonic findings in drowning deaths and inconclusive autopsy findings caused by postmortem changes. The aim of the present study was to investigate the pathway taken by inhaled drowning medium through the airway after death in a variety of experimental conditions, including underwater pressurization. We used methylene blue dye to monitor the spread of drowning medium to the lungs. Results of theses experiments demonstrated that it is possible for a significant amount of downing medium to enter the airway during immersion after death. Our results suggest that autopsies of immersed bodies and interpretation of these findings should be performed with special care.

Fracture of the femur during total hip arthroplasty presents the simultaneous problems of prosthetic stability and fracture treatment. The treatment of such fractures can be complex and is one of the major challenges and this complication is associated with a high morbidity and a significant delay in convalescence. Among the 237 cases, who were treated by cementless total hip arthroplasty from Jan. 1986 to Dec. 1992, 13 cases of femoral fracture were experienced. They usually occured during insertion of prosthesis and preparation of the medullary canal. There were 6 cases of type II fracture, 1 case of type III fracture, 5 cases of type IV fracture and 1 case of type V fracture according to AAOS classification. All of the fracture healed, but the prognosis of these cases must be determined by follow up. We recommend that femoral fractures can be prevented by accurate preoperative evaluation of the size of the femoral canal, identification and management of the predisposing factors for intraoperative fractures.

About 85-97% of patients get to lose an ejaculatory function with a little difference according to the level of spinal cord injury. Fifty eight trials of electroejaculation stimulation were performed in total 17 patients that failed in chemoejaculation with physostigmine. Mean age was 36.9 years. Of the 17 spinal cord injured patients, 1 had cervical, 13 thoracic 3 lumbar paraplegia; 7 had complete and 10 had incomplete lesions. Semens could be obtained in 14 patients ( 82.4%) among total 17 patients and in 51 of total 58 trials( 87.9%). Average total sperm counts and motile sperm numbers were 35.98 x 106 and 6.09 x 106 respectively in the obtained semen. However, motility was very poor. We performed more than 4 trials in 6 patients, but there results were not predictable. Two pregnancies were achieved in their spouse after an artificial insemination. Side effects were trivial. and there were lower abdominal discomforts or pains in 7 patients among incomplete paraplegics. In conclusion we could expect high successful rates of ejaculation in anejaculatory spinal cord injured patients by electroejaculation stimulation in case of the failure in chemoejaculation. However, we suggest that in vitro fertilization with advanced recent technology should be tried with adequate preparation after an experimental electroejaculation, because a quality of sperm motility was very poor and sperm motility was not improved after several trials.

BACKGROUNDS: Obstructive sleep apnea syndrome(OSA) can divided into two groups, positional (PP) and non-positional(NPP) obstructive sleep apnea syndrome, according to the body position while sleeping. In this study, we evaluated the differences of anthropometirc data and polysomnographic recordings between the two types of sleep apnea syndrome. MATERIALS: Fifty patients with OSA were divided two groups by Cartwright's criteria. The supine respiratory disturbance index (RDI) was at least two times higher than the lateral RDI in the PP group, and the supine RDI was less than twice the lateral RDI in the NPP group. This patients underwent standardized polysomnographic recordings. The anthropometirc data and polysomnographic data were analyzed, statistically. RESULTS: Of all 50 patients, 30% were found to be positional OSA. BMI was significantly higher in the PP group(p<0.05). Total sleep time was significantly longer in the PP group (350.6±46.0min, p<0.05). Sleep efficiency was high in the PP group(89.6± 6.4%, 85.6±9.9%, p<0.05). Deep sleep was significantly higher and light sleep was lower in the PP group than in the NPP group but no difference was observed in REM sleep between the two groups. Apnea index(AI) and RDI were significantly lower(17.0±10.6, 28.5±13.3, p<0.05) and mean arterial oxygen saturation was higher in the PP group(92.7 ±1.8%, p<0.05) than in the NPP group. CONCLUSION: Body position during sleep has a profound effect on the frequency and severity of breathing abnormalities in OSA patients. A polysomnographic evaluation for suspected OSA patients must include monitoring of the body position. Breathing function in OSA patients can be improved by controlling their obesity and through postural therapy.
