Selected AbstractsMolecular adsorbent recirculating system treatment for patients with liver failure: the Hong Kong experienceLIVER INTERNATIONAL, Issue 6 2006Alexander Chiu Abstract: Background: The molecular adsorbent recirculating system (MARS) is an extracorporeal liver dialysis system that allows selective removal of bilirubin and other albumin-bound toxins. We reported here our experience with the use of this technique for management of liver failure at Queen Mary Hospital, Hong Kong. Methods: From December 2002 to 2004, a total of 74 MARS sessions were performed on 22 patients. The cause of liver failure included acute liver failure (n=2), acute on chronic liver failure (n=12), posthepatectomy liver failure (n=4), and posttransplantation allograft failure (n=4). Results: MARS treatment showed significant reduction in total bilirubin level, serum ammonia level and blood urea, and nitrogen (P<0.001 for all three parameters). Five patients (22.7%) were able to bridge to transplantation and one patient (4.5%) made a spontaneous recovery. The 30-day mortality rate was 72.7%. Conclusions: Our results indicated that MARS can effectively improve serum biochemistry and is suitable for temporarily supporting patients with liver failure where transplantation is not immediately available. There is, however, no clear evidence showing that MARS can increase survival, improve the chance of transplantation or assist liver regeneration. Future studies in the form of randomized-controlled trials are crucial to characterize the true potential of this treatment. [source] Pulmonary sequelae in long-term survivors of bronchopulmonary dysplasiaPEDIATRICS INTERNATIONAL, Issue 6 2000Daniel Kwok-Keung Ng AbstractBackground: Bronchopulmonary dysplasia (BPD) is a common problem in premature babies. Long-term sequelae are the main concerns. Methods: A retrospective review of all BPD children born in Queen Mary Hospital, a teaching hospital of the University of Hong Kong, from January 1987 to December 1995 was conducted. Children with cerebral palsy, immunodeficiency, congenital heart disorders, renal or liver failure were excluded from analysis. Chest radiography (CXR), electrocardiogram (ECG) and pulse oximetry were routinely performed. Results: Fifty-five children completed the study. The female to male ratio was 1 : 1.1. The mean gestational age was 28 weeks. Twenty-five children were born with a birthweight of less than 1001 g. Mean age at assessment was 5.4 years. Twenty-four children (44%) demonstrated signs or symptoms of current asthma. Only seven children managed to perform the spirometry satisfactorily. One child had low forced vital capacity and one had hyperresponsive airway. The only risk factor found to be associated with current asthma was the birth month, with those children born early in the year at higher risk of developing current asthma. Seventeen of 48 children (35%) had a bodyweight below the third percentile at the corrected age of 1 year. Eleven of these seventeen children (65%) demonstrated catch-up growth at assessment. Abnormal CXR was found in 25 of 40 children (63%). All had normal pulse oximetry and ECG. Conclusions: Bronchopulmonary dysplasia children had a significantly higher risk than the general population of developing current asthma (odds ratio 4.7; 95% confidence interval 3.4,6.5; P<0.0001). The importance of birth month suggests that early life experience is important in the pathogenesis of asthma, even in BPD children. The long-term growth of BPD children was much better than previously reported. [source] Results of percutaneous transhepatic cholecystostomy for high surgical risk patients with acute cholecystitisANZ JOURNAL OF SURGERY, Issue 4 2010Kenneth S. H. Chok Abstract Aim:, To assess the efficacy and safety of percutaneous transhepatic cholecystostomy (PTC) in treatment for acute cholecystitis in high surgical risk patients. Patients and methods:, A retrospective review was carried out from January 1999 to June 2007 on 23 patients, 11 males and 12 females, who underwent PTC for the management of acute cholecystitis at the Department of Surgery, Queen Mary Hospital, Hong Kong, China. The mean age of the patients was 83. They all had either clinical or radiological evidence of acute cholecystitis and had significant pre-morbid diseases. The median follow-up period on them was 35 months. Results:, All the PTCs performed were technically successful. One patient died from procedure-related haemoperitoneum, while 87% (n= 20) of all the patients had clinical resolution of sepsis by 20 h after PTC. Eight patients underwent elective cholecystectomy afterwards (62.5% with the laparoscopic approach). Eight patients had dislodgement of the PTC catheter and one of them developed recurrent acute cholecystitis 3 months after PTC. That patient was treated conservatively. Four patients died from their pre-morbid conditions during the follow-up period. Conclusion:, PTC was a safe and effective alternative for treating acute cholecystitis in this group of patients. Thirteen of them without elective cholecystectomy performed did not have recurrent acute cholecystitis after a single session of PTC. It may be considered as a definitive treatment for this group of patients. [source] Labour characteristics and uterine activity: misoprostol compared with oxytocin in women at term with prelabour rupture of the membranesBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 2 2000Suk Wai Ngai Assistant Professor Objective To compare the labour pattern and uterine activity of oral misoprostol with oxytocin for labour induction in women presenting with prelabour rupture of membranes at term. Design Prospective randomised study. Setting Department of Obstetrics and Gynaecology, Queen Mary Hospital, Hong Kong. Participants Eighty women presenting with prelabour rupture of membranes at term. Methods The women were randomised to receive either 100 ,g misoprostol orally every 4 hours to a maximum of three doses, or intravenous oxytocin infusion according to the hospital protocol. Intrauterine pressure transducers were inserted one hour before induction of labour in both groups of women. We compared the pattern of uterine activity, the induction-to-delivery interval, duration of labour, mode of delivery and neonatal outcome between the two groups. Results Both oxytocin and oral misoprostol caused an increase in uterine activity within one hour of labour induction. Peak uterine activity was reached 6,8 h after oral misoprostol, with persistent effects, and 8,10 h after oxytocin, requiring continuous titration of medication. The duration of labour was significantly reduced in nulliparous women, but not in those who were multiparous in the misoprostol group. The induction-to-delivery interval, the mode of delivery and the perinatal outcome were similar for the two groups. Conclusion Oral misoprostol caused earlier peak uterine activity, compared with oxytocin (6,8 h vs 8,10 h). Oral misoprostol was not only as effective as oxytocin in inducing labour in women at term with prelabour rupture of the membranes, but it reduced significantly the duration of labour in nulliparous women. [source] Results of longterm hospital based cytological screening in asymptomatic womenDIAGNOSTIC CYTOPATHOLOGY, Issue 3 2006Jata S. Misra Ph.D., M.I.A.C. Abstract Routine cytological screening has been carried out in 27,062 asymptomatic women attending Gynaec and Family Planning O.P.D. of Queen Mary's Hospital, Lucknow, India (April 1971,December 2004). Incidence of squamous intraepithelial lesion (SIL) was found to be 5.9% in the series, while cervical malignancy was seen in 0.6% of cases. The study highlighted the immense utility of cytological screening in minimizing the incidence of carcinoma cervix in the segment of the urban population screened, as the incidence dropped down to 0.5% in the second half from 1.1% noticed in the first half of the screening period. The study also emphasized the utility of clinically downstaging the cervical cancer as 7,316 women showing clinical lesions of cervix were found to harbor SIL in 15.3% and carcinoma cervix in 1.3% of cases as against the incidence of 2.5% for SIL and 0.6% for frank cancer in women with normal cervix. The investigation into different risk factors involved in cervical carcinogenesis revealed that the incidence of SIL and cancer cervix showed a rise with increasing age and parity and prolonged sexual period. The incidences of both cervical cytopathologies were also higher in women of low socio-economic status while religion was found to have no bearing on the occurrence of the disease. Among the four sexually transmitted diseases (STDs) diagnosed in the cervical smears, Trichomonas vaginalis was found to be more prevalent (2.6%), while human papillomavirus (HPV) and Herpes simplex was seen in 0.4 and 0.2% of cases, respectively Herpes simplex was found to have strong affinity with both SIL and carcinoma cervix, while only SIL incidence was high with HPV infection. The study emphasizes need of proper education to women of low socio-economic class for creating awareness regarding hazards and risk factors of cervical cancer as well as management and cure of the disease.
