The clinical records of 22 Chinese patients with ulcerative colitis (UC) seen in Vancouver, British Columbia from 1975 to 1989 were reviewed. There was a predominance of males, with a male to female ratio of 1.75:1. The age range at diagnosis was 14 to 67 years (mean 38.9). Eighteen of the 22 patients were immigrants, and one was a visitor from Hong Kong. The age at diagnosis of the three Canadian-born patients (14, 26 and 26 years old) was less than the mean age at diagnosis of the immigrant group. The immigrants had resided in Canada for a mean of 9.3 years before developing symptoms of UC. Despite the rarity of UC in Hong Kong, 59% of the Chinese patients in this series were Hong Kong immigrants. This study demonstrates that UC is not as uncommon a disease in Chinese as had been previously perceived. Adequate time is apparently necessary for exposure to environmental factors in the pathogenesis of UC. The opportunity for continued study of defined ethnic immigrant populations in North America may yield useful information related to environmental factors that may be important in the etiology and pathogenesis of UC.

Objectives: To determine the frequency of patients passing the impacted esophageal meat bolus by conservative management Methods: After obtaining permission from ethical committee of Hospital,a total of 62 patients meeting the study criteria were recruited in the study which was conducted in Department of Otorhinolaryn-gology, Services Hospital, Lahore. Demographic information (name, age, gender, contact) was also obtained. Patients with clinical suspicion of impacted esophageal food bolus of age 20-50 years of either gender were included. Patients with known esophageal abnormalities like stricture, web or growth on either barium swallow or esophagogastroduodenoscopy, peptic ulcer and GERD were excluded. After taking informed written consent from each patient, single intravenous dose of buscopan 20mg was given to each patient. Each patient was followed by the researcher himself for 24 hours to assess the passage of food bolus. Results: 20-50 years was the age range in our study, with mean age being 34.10± .63 years. Majority of the patients 32 (51.61%) were between 20 to 35 years of age. Out of 62 subjects, 37 (59.68%) were male, 25 (40.32%) were females with male to female ratio 1.5:1. In our study, Frequency of patients passing the impacted esophageal meat bolus by conservative management was found in 51 (82.26%) patients. Conclusion: This study concluded that there is a high frequency of patients passing the impacted esophageal meat bolus by conservative management.

Objectives: The objective of the study was to compare the outcome of Classical Dacrocystorhinostomy(DCR) alone or with Slicon intubation in patients of primary nasolacrimal duct obstruction.Study design: This is a randomized prospective interventional study performed at Saidu Teaching Hospitalform from 1st January'2006 to 31st December 2006.Material and methods: Diagnosis of nasolacrimal duct obstruction was made on basis of history, clinicalexamination, regurgitation test and syringing of the nasolacrimal passage. Patients were selected byconvenient sampling and were randomized to two groups, for DCR with and without Silicon tube. Silicontube was removed after 4 months of surgery. Patients were followed up to 6 months.Results: Total number of patients was one hundred. Fifty (50%) patients were operated with siliconintubation and 50 (50%) without silicon intubation. Male to female ratio was 1:1.27.Age range was 15 yearsto 80 years. Mean, median and mode ages were 42.54, 47 and 30 years respectively. Eleven patients werelost from the study at various stages and were not included in the results of the study. The complicationsnoted were silicon tube loss in 2 cases, silicon tube displacement in 3 cases and DCR failure in 4 cases.Among the failure, 2 cases belonged to each group with and without silicon intubation.Conclusions: We conclude that the complications rate with and without silicon intubation is the same inprimary nasolacrimal duct obstruction. It is therefore, recommended that silicon intubation may not benecessary in such cases.Key words: DCR, Intubation, NLD Obstruction.

PURPOSE To study the clinical features and outcome for primary non-Hodgkin's lymphomas of the nose/nasopharynx (NNP-NHLs) according to immunophenotype. PATIENTS AND METHODS One hundred thirteen Chinese patients with primary NNP-NHLs that belonged to the categories E, F, G, or H according to the Working Formulation (WF), with full immunophenotypic data and complete clinical follow-up data, were analyzed in this retrospective study. RESULTS Ninety (79.6%) patients had localized (stage I or II) disease, while 23 (20.4%) had stage III or IV disease. The lymphomas in 51 (45.1%), 24 (21.3%), and 38 (33.6%) patients showed natural killer (NK)/T- (CD56-positive), T-cell, and B-cell immunophenotype, respectively. Seventy-three patients (65.8%) achieved a complete remission, of whom 34 (46.6%) subsequently relapsed. The median follow-up time for those alive was 88 months. The 5-year actuarial disease-free and overall survival rates were 34.4% and 37.9%, respectively. Multivariate analysis showed that only stage and immunophenotype were significant for survival. NK/T lymphomas were distinctive among the three immunophenotypes in the following aspects: the highest male-to-female ratio, more frequent involvement of the nasal cavity alone, higher risk of dissemination to the skin, more frequent development of hemophagocytic syndrome, and the worst prognosis (overall median survival, 12.5 months). CONCLUSION The three immunophenotypes studied are shown to exhibit different clinical patterns. Since the NK/T phenotype carries the worst prognosis, patients who present with NNP-NHL should have their tumors analyzed for CD56 expression.

We examined the epidemiological profiles and characteristics of suicide attempters admitted to the Accident and Emergency Department of a regional hospital in Hong Kong (Princess Margaret Hospital) in the period from January to December 1995. These consisted of 101 adolescents (16 males and 85 females) aged between 10 to 24 years. There were significantly more female attempters than males, especially in the group aged 10-19, which had a male-to-female ratio of suicide rates of 1:11. Most of the methods used were nonlethal; the attempters were not serious enough and had no real intention to die. The use of painkillers and sleeping pills was most common. The main precipitating factor was interpersonal problems, for example, relationships, spousal and parental problems, especially among teenage girls. More than 90% of the cases stayed at the hospital for further observation, the mean length of stay in the hospital being 3.3 days. The potential health cost to the hospital system was around HK$ 11.7 million. Underestimating the prevalence of attempted suicides in Hong Kong could be a serious matter.

A survey of 62 drug deaths in Glasgow showed a wider age range than expected (16–49), a high male to female ratio (44:18) and, where mode of employment had been recorded, a high degree of unemployment (91%). The majority of deaths occurred near centres of known supply. Although a number occurred in the family home, a large proportion were not at the place of residence. In only two cases was morphine detected alone. The majority of the deaths were from combinations of drugs, primarily with benzodiazepines.

Scales were collected from adult summer steelhead trout taken in 1967 and 1968 in an increasingly important sport fishery on the Babine River. The most common total age was 3.2 (73% in 1967 and 60% in 1968), and the second most common age was 3.3. The males tended to remain a year longer in the ocean than did females before first maturation. Four of 121 (3.3%) scales, all from female steelhead, indicated the fish had spawned once previously. The male to female ratio in the sport fishery was 1:1.33. Mean length at time of smolt outmigration as estimated from scales from 3.2 fish was 190 mm. These results are compared with what is known for other British Columbia steelhead stocks.

Laryngectomy for carcinoma of the larynx has been performed since it was first described in 1880. Since that time the complication of tracheostomal stenosis has plagued both surgeons and patients. The reported incidence of tracheostomal stenosis ranges from 4% to 42%. At West Virginia University Hospitals from 1976 to 1994, 106 patients undergoing laryngectomies on the head and neck oncology service were analyzed. The charts of patients treated before 1991 were reviewed retrospectively; a prospective analysis was initiated in 1991. Only patients with a minimum of 6 months of follow-up were included in this study. The male-to-female ratio was 3:1, with an age range of 28 to 86 years (mean, 58 years). The overall rate of stenosis was 28.4%. The incidence of tracheostomal stenosis was higher in women (46.4%) than in men (21.6%) ( p < 0.05). Since 1991 a plastic type of closure was used in 25 patients. The stenosis rate was 0% in these patients. Before 1991 a bevel or circle technique was used, with stenosis rates of 33% and 75%, respectively ( p < 0.05). Infection at the site of the stoma, fistula, steroid use, neck dissection, pectoralis major myocutaneous flap usage, primary tracheoesophageal puncture, and radiotherapy did not correlate with an increased incidence of stenosis. The most important factor in prevention of stomal stenosis after laryngectomy is attention to detail while forming the stoma. With good technique and a plastic-type closure to break up the suture line, a minimal rate of stenosis should be encountered.
