RESUMO

BACKGROUND: Because of the limitation of on-site neurology workforce, telestroke was implemented to overcome this barrier. We explored the efficacy and safety of intravenous (IV) stroke thrombolysis service by telestroke when neurologist was not available on-site. METHODS: From January 2009 to December 2012, we compared patients treated with IV stroke thrombolysis by telestroke in the form of telephone consultation with teleradiology, to patients treated after in-person assessment by the same team of neurologists in a regional hospital. Door-to-needle time, symptomatic intracranial hemorrhage, and functional outcome at 3 months were prospectively collected and compared between the groups. RESULTS: In all, 152 patients were treated with IV thrombolysis; 102 patients were treated with neurologist on-site; whereas 50 patients were treated by internists with telestroke. Fifty-two percent of the telemedical group achieved excellent outcome compared to 43% of the neurologist on-site group (P = .30). Symptomatic intracranial hemorrhage rate (4.0% versus 4.9%, P = 1.0) and mortality (8.3% versus 11.9%, P = .49) were comparable. Using the multiple logistic regression analysis, age, baseline stroke severity, and extent of early ischemic change on brain computed tomography scan, are independent predictors for excellent outcome, whereas the presence of neurologist on-site is not correlated with the outcome. CONCLUSIONS: Patients treated without neurologist on-site achieved similar outcome. Telephone consultation and teleradiology-guided IV stroke thrombolysis, with the support of on-site internist appeared safe and efficacious.

RESUMO

BACKGROUND: Multiple sclerosis (MS) has a low prevalence in Hong Kong. OBJECTIVE: To reassess MS prevalence in Hong Kong and to examine associated risk factors for relapsing-remitting type MS patients to reach Kurtzke's Extended Disability Status Scale (EDSS) of 6.0, i.e. when walking aid was needed. DESIGN: Retrospective observational study on MS patients over 11 years. SETTING: Three tertiary hospitals in Hong Kong. RESULTS: A hundred and six patients were recruited. Female to male ratio was 3.2:1 and the prevalence was 4.8 per 100,000. 95 were relapsing-remitting (RR) type. The mean disease duration was 12.7 years (range: 1-45 years) and the duration of follow up was 11.0+/-0.8 (mean+/-SE) years. The initial mean EDSS was 1.59 and the latest mean EDSS was 4.26. 38 (40%) RR type MS patients progressed to EDSS 6.0 after a mean duration of 6.0 years. With Cox regression analysis, patients with older age (>35y) of onset (HR 2.57; 95% CI:1.29-5.11), higher EDSS of 2.0 or more upon presentation (HR 2.19; 95%CI: 1.12-4.26) were associated with progression to EDSS of 6.0, while there was a tendency towards slower disease progression for patients initially presenting with optic symptoms (HR 0.52; 95%CI: 0.23-1.16). The number of relapses and use of interferon could not be shown to have significant effect on disease progression. CONCLUSIONS: The local period prevalence ratio of MS was 4.8 per 100,000. Older age of onset and higher EDSS upon initial presentation were independent predictors for progression to EDSS of 6.0.

RESUMO

BACKGROUND: HIV and highly active antiretroviral therapies have been associated with changes in individuals' lipid profiles and fat distribution (lipodystrophy). A pilot study was conducted for a randomised controlled trial to evaluate whether lipodystrophy in HIV patients can be controlled by adopting the low-fat and low-cholesterol diet or the modified Mediterranean diet. METHODS: Forty-eight HIV patients were randomised into two diet groups. Thirty-six (75%) completed the 1-year pilot study with regular dietetic consultations, during which time lipid levels, weight, body mass index and fat distribution were recorded. Differences between and within groups were determined. RESULTS: Undesirable body fat changes in the low-fat diet group included decreases in tricep skinfold (from 19.9 mm to 15.4 mm (P = 0.03)), hip circumference (from 93.6 cm to 91.7 cm (P = 0.01)) but a significant increase in waist-to-hip ratio (from 0.87 to 0.89 (P = 0.003)). Serum cholesterol increased significantly in the Mediterranean diet group at 9 and 12 months (from 4.6 to 5.06 mmol L(-1) (P = 0.03) and 5.12 mmol L(-1) (P = 0.01)) with no obvious change in the low-fat diet group. Serum triglyceride levels remained the same in the Mediterranean diet group, whereas it increased from 1.9 to 3.22 mmol L(-1) (P = 0.07) in the low-fat diet group. CONCLUSIONS: A Mediterranean diet seems to have an advantage over the low-fat diet in maintaining serum triglyceride levels and avoiding lipodystrophy, but this advantage was offset by a rise in cholesterol level. Several procedural and methodological issues were identified which must be rectified before a similar large-scale trial taking place.

RESUMO

The Hong Kong HIV Cohort Database is an observational cohort including all patients enrolled in 2 HIV specialist clinical services in Hong Kong. Basic demographics, HIV transmission category, and the diagnoses of AIDS were captured using a standardized template. As of December 2006, 2132 HIV cases had been registered in the database, representing two thirds of all reports submitted to the government's surveillance system. Non-Chinese and young females≤24 years were less represented in the cohort. Description of cohort cases was, however, more complete in terms of transmission category and presentation with AIDS-defining illnesses. Overall, Pneumocystis jirovecci, tuberculosis, and systemic mycosis accounted for a majority of AIDS cases within 3 months of HIV diagnosis. There was a gradual rise of HIV positive men having sex with men in the cohort, notably after 2002, an observation also made in other Asian countries.

RESUMO

We describe an 84-year-old man with an unusual clinical presentation of palatal tremor in association with ciprofloxacin treatment. The patient had rhythmical movements not only of the soft palate but also of the face and trunk. Complete resolution of the symptoms occurred 2 days after discontinuation of ciprofloxacin and administration of sodium valproate. This is the first reported case of palatal tremor secondary to the use of ciprofloxacin.
