Trends in hospitalizations and mortality due to medicinal or non-medicinal poisonings in Hong Kong

Previous epidemiologic studies of poisonings in Hong Kong are regional hospital-or poison information center-based and have focused on either adults or children. This paper reports on the territory-wide hospitalization and mortality rates, comparing medicinal and non-medicinal poisonings in the general population. Between 1980 and 1995, the figures for hospitalizations and mortality due to medicinal (ICD codes 960-977) or non-medicinal (ICD codes 980-989) poisonings were obtained from the Annual Reports of the Department of Health, Hong Kong Government. Rates of medicinal poisonings increased between 1980/81 (57.3/100,000) and 1987/88 (80.9/100,000), but then declined (59.1/100,000) in 1993/94. Rates of non-medicinal poisonings were rather static (49-53/100,000) between 1980/81 and 1988/89, but then declined (22.0/100,000) in 1994/95. Between 1980/81 and 1988/89, rates of fatal medicinal poisonings (0.73-1.31/100,000) were similar to those of fatal non-medicinal poisonings (0.98-1.70/100,000). However, from 1989/90, there was an increase in the rates of fatal medicinal poisonings (1.94-2.80/100,000), although rates for non-medicinal poisonings remained much the same (0.80-1.38/100,000). Hospitalizations due to poisonings are now less common in Hong Kong than before, due largely to a greater decline in non-medicinal poisonings.     

Spinal epidural abscess--a case report

Despite modern medical advances, the morbidity and mortality rates associated with spinal epidural abscess remain significant, and the diagnosis is elusive. The incidence of spinal epidural abscess is approximately one to two cases per 10,000 among all patients admitted to hospitals. The symptoms of spinal epidural abscess are varied but include lower back pain, fever, local tenderness and neurological deficit especially in such high risk groups as patients with diabetes, intravenous drug abuse, chronic renal failure, alcoholism, liver disease and immunocompromization. Accumulation of data is difficult in that many physicians will never see a case during their careers. Herein, we present a case with lower back pain associated with both lower legs weakness. His abdomenon CT revealed retroperitonium and right perirenal abscess. External drainage as well as antibiotic treatment was done immediately. However, the lower legs weakness became severe and a lumbar spine MRI revealed T11-L4 epidural abscesses and L2-3 intervertebral space pus formation. Then, the patient was transfered to our Neurosurgical Ward for further treatment. His postoperative condition improved in both lower legs. This case report is to enhance the recognition and treatment of spinal epidural abscess, a rare affliction.     

MRI-guided stereotatic aspiration for the treatment of deep-seated tentorial empyema: a case report

The purpose of this study was to evaluate the prenatal characteristics of congenital nephrosis of the Finnish type (CNF). Patients presenting with elevated maternal serum and/or amniotic fluid alpha-fetoprotein levels, normal ultrasound examinations and normal fetal karyotypes were included. A retrospective cohort study was conducted using questionnaires sent to all board certified clinical geneticists. Perinatal outcome, including histologic verification of CNF, was obtained. Forty index cases met the above criteria. Ten cases ultimately did not have the diagnosis of CNF, with a median MSAFP level of 7.59 MoM (range 2.7-27.64 MoM) and a median AFAFP level of 10.99 MoM (range 1.47-128.6 MoM). In the affected cohort of index pregnancies, the initial median MSAFP level was 14.49 MoM (range 3.1-38.0 MoM); the median AFAFP level was 40.0 MoM (range 2.4-80.9). MSAFP and AFAFP levels may be lower than previously recognized in patients carrying fetuses with CNF. There is significant overlap between the affected and unaffected patients.
