The New Mental Health and Welfare Law in Korea: Issues with Additional Diagnosis by External Psychiatrist and the Role of Admission Review Committee / 신경정신의학

The new Mental Health and Welfare Law in Korea was revised to require additional diagnosis by a psychiatrist from another public or designated hospital for involuntary admission beyond 2 weeks. In addition, it features the newly established Admission Review Committee for better protection of human rights. The provision of the additional diagnosis by an external psychiatrist resulted from misinformation about the distinction between the second opinion for medical assessment and the review of admission by independent authorities. An additional diagnosis is not required by an external doctor since it is not for review of adequacy of admission but just for second opinion for better medical assessment. Given the limited number of qualified public hospital psychiatrists, additional diagnosis by external psychiatrists does not seem practical unless private hospital doctors are required to visit neighboring hospitals. The current method of cross checking between neighboring doctors is not in accordance with the principles that review should be done by independent authorities. The Admission Review Committee also does not seem to serve the purpose since the role of the Committee is limited to document review, while the proper role of the Committee is left to individual doctors. Admission review should be performed through a thorough interview with the patient by a judicial (or quasi-judicial) authority. Law revision is urgently needed to ensure proper judicial (or quasi-judicial) review of admission, and to streamline unnecessary procedures such as the additional diagnosis by external doctors.

Schistosoma mansoni in a low-prevalence area in Brazil: the importance of additional methods for the diagnosis of hard-to-detect individual carriers by low-cost immunological assays

Schistosomiasis diagnosis is based on the detection of eggs in the faeces, which is laborious and lacks sensitivity, especially for patients with a low parasite burden. Immunological assays for specific antibody detection are available, but they usually demonstrate low sensitivity and/or specificity. In this study, two simple immunological assays were evaluated for the detection of soluble Schistosoma mansoni adult worm preparation (SWAP) and egg-specific IgGs. These studies have not yet been evaluated for patients with low parasite burdens. Residents of an endemic area in Brazil donated sera and faecal samples for our study. The patients were initially diagnosed by a rigorous Kato-Katz analysis of 18 thick smears from four different stool samples. The ELISA-SWAP was successful for human diagnosis with 90% sensitivity and specificity, confirming the Kato-Katz diagnosis with nearly perfect agreement, as seen by the Kappa index (0.85). Although the ELISA-soluble S. mansoni egg antigen was 85% sensitive, it exhibited low specificity (80%; Kappa index: 0.75) and was more susceptible to cross-reactivity. We believe that immunological assays should be used in conjunction with Kato-Katz analysis as a supplementary tool for the diagnosis of schistosomiasis for patients with low infection burdens, which are usually hard to detect.
