Biliary‐enteric bypass in unresectable malignant hilar biliary obstruction: Kwong Wah Hospital experience

Objective : To evaluate the efficacy of biliary‐enteric bypass in the palliation of malignant hilar biliary obstruction. Materials and Methods : Records of 19 patients from 1995 to 1998 were reviewed. There were 13 patients with cholangiocarcinoma and 6 patients with carcinoma of the gallbladder. Single biliary‐enteric bypass had been performed in 13 of the patients; the rest had more than one biliary‐enteric anastomosis. Results : The 30‐day mortality was 21% (4/19 patients). Bile leakage occurred in 2 patients, leading, in both, to fatality. Excluding the 30‐day mortality, the median survival of patients with carcinoma of the gallbladder and cholangiocarcinoma was 116 days (43–200) and 202 days (47–1207), respectively. The mean hospital stay was 31 days (13–59) and all patients were discharged with their symptoms relieved and a drop in bilirubin of at least two‐thirds their pre‐operative level. The late complication rate was 26.7% (4/15 patients). Conclusion : Biliary‐enteric bypass is effective in the palliation of symptoms of patients suffering from unresectable hilar biliary obstruction, although it carries considerable mortality and morbidity. Stenting, rather than surgery, should be considered for patients with unresectable gallbladder cancer.      

Tuberculous meningitis in children

Between May 1988 and November 1992 the data from 52 patients with tuberculous meningitis (TBM) were noted down for their symptoms and signs, BCG vaccines, PPD tests; clinical, laboratory, radiologic and microbiologic findings. These data were discussed by means of literature knowledge. Cranial computed tomography (CT) demonstrated hydrocephalus (HC) in 98% of the patients. There was a statistically significant difference among the clinical stages on admission in respect to prognosis (P < 0.05). In addition, there was also a significant relationship between prognosis and HC (P < 0.05). However, we did not find any significant relationship between parenchymal involvement, basilar meningitis and prognosis (P > 0.05).     

Effects of BCG Vaccination on Evolution of Leprosy

Background

BCG vaccine is considered to have immunoprophylactic potential in leprosy. However controversy exists about the extent of prophylaxis it provides. In view of this, a study was undertaken to see the evolution of disease in established cases of leprosy who were already vaccinated with BCG and to compare it with the cases of leprosy who were not vaccinated with BCG.

Methods

114 newly diagnosed cases of leprosy were studied. Patients were divided into two groups-BCG vaccinated and non-vaccinated. Clinical diagnosis of leprosy was confirmed by bacteriological and histopathological studies in each case. All patients were given standard anti leprosy treatment and were evaluated monthly for a minimum period of one year.

Results

All the cases were males in the age group of 20 to 50 years. 25.4% of cases had received BCG vaccine and 74.6% were not vaccinated for the same. No significant difference was observed in the incidence of different types of leprosy in vaccinated and non-vaccinated groups. 25.9% cases in non-vaccinated group developed lepra reaction as compared to 13.8% in vaccinated group. The incidence of deformities and disabilities in vaccinated group was only 10.3% as against 18.8% in non-vaccinated group. The rate of bacillary clearance appeared faster in vaccinated group.

Conclusions

Although there is no significant difference in the pattern of different types of leprosy in BCG vaccinated and non-vaccinated cases, there is reduction in the incidence of reactions as well as deformities and disabilities in BCG vaccinated cases as compared to non-vaccinated cases.Key Words: BCG Vaccine, Leprosy     

Correction of Lower Limb Deformities Using Ilizarov's Technique

Background

India accounts for approximately 10 million orthopaedically handicapped children and adults with limb deformity. Ilizarov ring fixator could treat most of these deformities.

Methods

Twenty cases of deformities of lower limb managed with Ilizarov technique during period between March 2001 and February 2003 were studied.

Results

55% were in the age group of 11-30 years. Out of the 20 cases studied, 6 were congenital talipes equino varus, 8 were fixed flexion deformity of knee, 4 were equines deformity of the ankle and 2 were malunited fracture shaft of tibia.4 patients who had recurrence were operated for fixed flexion deformity of the knee. The main complication encountered was pin tract infection, which was seen in 15(75%) cases. In 16(80%) cases, the results were excellent with no recurrence of deformity and patients were able to walk independently. In 4 (20%) cases, recurrence was mild to moderate (10 to 20) but all of them were able to ambulate idependently and carry out their routine activities.

Conclusion

Ilizarov ring fixator is a superior compared to conventional methods for correction of deformities of lower limb.Key Words: Ilizarov method, Ligamentotaxis, Distraction     

Effect of short-term Psychiatric Intervention in Cancer Patients

A total of 50 patients undergoing cancer treatment at Malignant Disease Treatment Centre were included in the present study aimed at evaluating the psychological status of cancer patients. All patients filled a specially designed proforma and the following psychological questionnaires : General Health Questionnaire, Carroll Rating Scale for Depression, State-Trait Anxiety Inventory, PGI General Well-being Scale and Quality of Life Scale. Analysis of the results showed that 22 (44%) of the cancer patients had psychiatric disorders and this number had reduced to 12 (24%) after therapy. The difference was statistically significant. Psychiatric treatment also resulted in a statistically significant reduction in level of depression as measured by Carroll Rating Scale for depression. Short term psychiatric treatment was found to be very useful in treating psychiatric morbidity and depression in cancer patients.Key Words: Cancer, Depression, Psychiatric morbidity     

Impact of oral direct thrombin inhibitors on anticoagulation clinics

OBJECTIVES: To characterize the services and activities performed by anticoagulation clinics (ACCs) across the United States, examine the anticipated impact that oral direct thrombin inhibitors (DTIs) will have on the clinical services of ACCs, and elicit possible management strategies to realign services provided by ACCs and opportunities for restructuring clinical services. METHODS: A survey was developed in consultation with content experts in the field, pretested by several ACC providers, and subsequently refined. Surveys were mailed to 400 randomly selected ACC-based providers. RESULTS: The final usable response rate was 34.5% (115 of 333 surveys). Respondents anticipated that the number of patient visits/month would decrease from a median of 336 (interquartile range [IQR] 151-775) to 150 (IQR 71-350, p<0.001) after the introduction of oral DTIs. In addition, time spent on many direct and indirect patient care activities currently performed by ACCs was expected to decline. Respondents indicated that ACCs may find new roles by providing guidance on individual suitability for therapy, managing the transition to oral DTIs, providing education for patients and health care providers on thrombotic disease state management, monitoring patients for recurrent thrombosis and risk of bleeding complications, monitoring patient compliance, and providing counseling and safety surveillance for patients receiving treatment with oral DTIs. CONCLUSION: The advent of oral DTIs is likely to have a significant impact on the structure and delivery of antithrombotic services. Clinics that are proactive and redesign their patient care services to consider emerging anticoagulant agents will be more likely to remain relevant and viable.
