OBJECTIVE: Many people dealing with Parkinson’s disease (PD) turn to complementary and alternative medicine when searching for a cure or relief from symptoms. Acupuncture is widely used in the Korean PD population to alleviate symptoms and in hopes of curing the illness. However, acupuncture use for PD patients has only recently begun to be studied scientifically and is still considered an unproven treatment for PD. Therefore, there is an urgent need for acupuncture to be studied, validated and used for PD. Thus, our study’s aim is to examine how many acupuncture studies in PD are registered and reported in Korea. METHODS: The registries Clinicaltrials.gov and the Clinical Research Information Service (CRIS) and the search engine PubMed were searched to find relevant human clinical studies involving acupuncture therapy in PD patients. We examined the registration of trials, the posting and publication of results, and whether published articles were registered. RESULTS: In Clinicaltrials.gov, one completed trial was found with published results. In CRIS, one completed trial was found with published results. A total of 6 publications were found in our study: 2 articles were registered, but only 1 had the registered trial number listed in the article. CONCLUSION: Acupuncture is popular among the PD population in Korea regardless of its unproven safety and efficacy. Despite the pressing need for clinical trials, the number of studies listed in the registries was small, and only a few publications were registered. More effort and rigor are needed to validate the efficacy and safety of acupuncture for PD.

BACKGROUND AND PURPOSE: Research on stem cells (SC) is growing rapidly in neurology, but clinical applications of SC for neurological disorders remain to be proven effective and safe. Human clinical trials need to be registered in registries in order to reduce publication bias and selective reporting. METHODS: We searched three databases—clinicaltrials.gov, the Clinical Research Information System (CRIS), and PubMed—for neurologically relevant SC-based human trials and articles in Korea. The registration of trials, posting and publication of results, and registration of published SC articles were examined. RESULTS: There were 17 completed trials registered at clinicaltrials.gov and the CRIS website, with results articles having been published for 5 of them. Our study found 16 publications, of which 1 was a review article, 1 was a protocol article, and 8 contained registered trial information. CONCLUSIONS: Many registered SC trials related to neurological disorders are not reported, while many SC-related publications are not registered in a public registry. These results support the presence of biased reporting and publication bias in SC trials related to neurological disorders in Korea.

INTRODUCTIONUnderstanding baseline epidemiology of intussusception (IS) in different geographical settings is important for the safety assessment of rotavirus vaccines. This paper presents IS surveillance data from Singapore between 1997 and 2007, including the period between November 2005 and December 2007 when rotavirus vaccines (primarily Rotarix) were available to newborns in Singapore.
MATERIALS AND METHODSCase ascertainment, collection, analyses and presentation of IS data was done as per recommendations of the Brighton Collaboration Working Group. For estimating the IS incidence rate in infants, live births for the years of the study were used as denominators, while for incidence in children age <2 years, the expected numbers of infant deaths occurring between 1 and 2 years of age was deducted from the combined live births for the 2 years, to obtain the denominator.
RESULTSThe incidence of IS among children aged <1 year throughout this 10-year period was higher than the incidence of IS in children between 1 and 2 years of age. In 2005, 2006 and 2007, the incidence of IS per 100,000 was 39.9, 26.4 and 35.6 in children aged <1 year and 26.2, 23.8 and 28.7 in children <2 years.
CONCLUSIONThis IS surveillance study provides reassuring preliminary evidence that there is no increase in the incidence of IS in Singapore after the introduction of rotavirus vaccines (including Rotarix) in Singapore.

INTRODUCTIONSingapore was one of 29 countries worldwide affected by severe acute respiratory syndrome (SARS) in 2003.
MATERIALS AND METHODSThere were 238 cases identified during the outbreak. We performed a retrospective analysis of the clinical and laboratory data of 234 patients admitted to Tan Tock Seng Hospital and Singapore General Hospital.
RESULTSThe mean age of patients was 21 years, 31.6% of patients were males and 41.8% were healthcare workers. At presentation, the common symptoms were fever, myalgia, cough and headache; rhinorrhoea was uncommon. On admission, 21% had leukopenia, 18% had thrombocytopaenia, 29% had hyponatraemia, 31% had hypokalaemia, 21% had transaminitis. Polymerase chain reaction (PCR) testing of respiratory and stool samples provided the best yield at the end of the first week of illness. Thirty-two patients were initially not recognised as probable SARS and were reclassified when the serology test results were available. The chief reasons for not identifying these patients early were persistently normal chest X-rays (68.8%), very mild presentation (43.8%) and the presence of a concomitant illness (12.5%). Overall, 12% of the patients were probable SARS with atypical presentations. Overall mortality was 11.8%.
CONCLUSIONPatients infected with the SARS coronavirus had a wide clinical presentation with non-specific symptoms.
