    Notes: Summary The level of somatostatin in the hypothalamus was higher in satiated rats than in hungry rats. Elevating hypothalamic somatostatin levels by administering somatostatin into the hypothalamus produced a decrease in food intake, whereas lowering hypothalamic somatostatin levels by administering cysteamine into the peritoneal cavity produced an increase in food intake in rats.

    Notes: Summary Our aim is to determine non-insulin-dependent diabetes mellitus (NIDDM) incidence in Taiwan and examine its relation to obesity and hyperinsulinaemia in Chinese men and women. A total of 995 men and 1195 women aged 35–74 years free from diabetes in two townships in Taiwan were followed up with a second examination. At baseline general and metabolic data were recorded, and detailed anthropometric parameters and plasma glucose and insulin were assessed. World Health Organisation (WHO) criteria of fasting glucose 7.8 mmol/l or greater was utilized for defining diabetes. The age-standardized incidence rate based on the United States population in 1970 was 9.3/1000 (CI 5.8–12.8) in men and 9.3/1000 (CI 6.2–12.4) in women and the based on the WHO population in 1976 was 8.9/1000 (CI .5–12.3) in men and 8.9/1000 (CI 5.9–11.9) in women for the Chinese who had a mean BMI slightly greater than 24 (kg/m2). The predictability of the plasma glucose level was greater than that of the insulin level and the obesity indices. NIDDM incidence increased approximately threefold with each 0.67 mmol/l increase in plasma glucose level in men and women. The present study demonstrated the essential relationship of not only BMI but also central obesity indices (such as subscapular and waist circumference) to the incidence of NIDDM among men and women and a stronger relationship between NIDDM incidence and obesity in women than in men. The predictive effects of obesity indices and fasting plasma insulin values on NIDDM risk were independent of each other in men. Obesity and hyperinsulinaemia each without the presence of the other can lead to an increased risk of NIDDM. In women the NIDDM incidence increased more than additively in those with both obesity and hyperinsulinaemia compared to those with single obesity or hyperinsulinaemia. A slightly higher incidence of NIDDM in Taiwan than in western countries was found. The importance of obesity is indicated for predicting NIDDM in the community. Hyperinsulinaemia was found to play a significant role in predicting NIDDM incidence independent of obesity in men and synergistically with obesity in women. [Diabetologia (1997) 40: 1431–1438]

    Notes: Abstract We evaluated the value of placement of a folded gauze square into the urogenital introitus to improve vaginal opacification in 90 patients who underwent defecography. Of the 50 patients who retained the gauze in the introitus, 96% demonstrated excellent or good vaginal opacification. By contrast, only 75% of the 40 patients who lost the gauze during the study were able to achieve the same level of opacification. This difference was shown to be statistically significant (p 〈 0.002), suggesting that placement of a folded gauze square in the introitus limits loss of contrast from the vagina, which improves vaginal opacification.

    Notes: Abstract Background: To determine whether direction of vaginal displacement during defecography aids in diagnosing pelvic floor pathology. Methods: Ninety patients underwent defecography over a 2-year period. Each study was retrospectively reviewed by three radiologists who recorded whether the vagina was displaced cephalad, caudad, or nondisplaced in relation to the urogenital hiatus. This information was then correlated with radiologic diagnosis rendered for the study. Results: Of the 26 patients with normal defecograms, 19 (73%; p 〈 0.001) demonstrated no vaginal displacement during the procedure. Comparatively, 10 (83%; p 〈 0.001) of the 12 patients with cystoceles showed caudad vaginal displacement, and no patients with cystoceles showed cephalad displacement of the vagina. Of the 17 patients with rectoceles, 10 (58%) showed cephalad displacement, one (6%) showed caudad displacement, and six (35%) patients showed no vaginal displacement. Thirteen (46%) of 28 patients with enteroceles showed cephalad vaginal displacement, nine (32%) showed no vaginal displacement, and six (21%) demonstrated caudad displacement. Conclusions: Caudad displacement of the opacified vagina suggests the presence of a cystocele. Cephalad vaginal displacement is suggestive of the presence of an enterocele or rectocele.

    Notes: Abstract Objective To evaluate the risk factors for postextubation laryngeal stridor and its prevention by hydrocortisone in adult patients.Design: Prospective, randomized, double-blind, placebo controlled study. Setting Medical and surgical ICU of a tertiary teaching hospital. Patients 77 consecutive patients of both sexes, who had undergone tracheal intubation for more than 24 h and fulfilled the weaning criteria, were eligible for the study. Patients were excluded if they were less than 15 years of age, had a disease or the surgery of the throat, or had been extubated during the current hospitalization. Intervention The control group received placebo (normal saline 3 cc) and the experimental group received hydrocortisone 100 mg by intravenous infusion 60 min before extubation. Main outcome measures Patients were observed 24 h after extubation for symptoms or signs of laryngeal edema or stridor: prolonged inspiration with accessory usage of respiratory muscles or crowing sound with inspiration or reintubation. Results The overall incidence of postextubation stridor was 22% (17/77). Only one patient (1%), who belonged to the control group, needed reintubation. 39% of female patients and 17% of male patients developed stridor. The relative risk of females developing this complication was 2.29. 7/39 of the hydrocortisone group and 10/38 of patients in the control group developed postextubation stridor.Conclusions: Hydrocortisone did not significantly reduce the incidence of postextubation laryngeal edema or stridor. From the risk factors evaluated, we were unable to demonstrate a statistical correlation between postextubation stidor and the duration of the intubation, the patient's age, the internal diameter of the endotracheal tube, or the route of intubation. However, female patients were more likely to develop this complication.

    Notes: Abstract Photoluminescence studies on porous silicon show that there are luminescence centers present in the surface states. By taking photoluminescence spectra of porous silicon with respect to temperature, a distinct peak can be observed in the temperature range 100–150 K. Both linear and nonlinear relationships were observed between excitation laser power and the photoluminescence intensity within this temperature range. In addition, there was a tendency for the photoluminescence peak to red shift at low temperature as well as at low excitation power. This is interpreted as indicating that the lower energy transition becomes dominant at low temperature and excitation power. The presence of these luminescence centers can be explained in terms of porous silicon as a mixture of silicon clusters and wires in which quantum confinement along with surface passivation would cause a mixing of Γ andX band structure between the surface states and the bulk. This mixing would allow the formation of luminescence centers.

    Notes: Summary ¶ Background. Radiation necrosis is a known complication following radiation therapy for extracranial as well as intracranial tumours. However, brain abscess formation in radiation necrosis has not been reported in the literature. We report the clinical data of 6 patients suffering from this condition.  Method. Twenty-eight patients with radiation necrosis of the temporal lobe following radiotherapy for nasopharyngeal carcinoma were treated surgically at the Department of Neurosurgery, Queen Elizabeth Hospital, Hong Kong between January 1992 and July 1999. Of these, 6 cases were complicated by brain abscess formation. The clinical data of these 6 patients are retrospectively reviewed.  Findings. The patients were 5 males and 1 female, ranging in age from 41 to 67 years. Three patients had previous treatment with steroids for the symptomatic radiation necrosis. A history of nasal infection or otitis media was recognised in all 6 patients. All patients were treated surgically by temporal lobectomy and excision of the necrotic tissue together with the abscess cavity. Intra-operatively, a bony defect was observed between the middle cranial fossa and the sphenoid sinus in 3 patients and the bony defect was repaired with a temporalis muscle flap. The species of organisms could only be identified in 3 patients. In 3 patients, the pus smear was positive but the culture was negative. Subsequently, 4 patients recovered and 2 patients died.  Interpretation. Cerebral radiation necrosis is a predisposing cause of brain abscess formation. Surgical excision is recommended as the treatment of choice in this group of patients.
