PURPOSE: Serotyping pneumococcal isolates is important to monitor efficacy of pneumococcal vaccines. Because of difficulties of typing pnueumocci, a multiplex bead-based (multibead) serotyping assay was recently introduced. The aim of this study is to establish a new multibead serotyping assay and to apply this method to analyze clinical isolates of pneumococci in Korea. METHODS: To establish the multibead serotyping assay, six key reagents were transferred from University of Alabama at Birmingham (UAB) to Ewha Center for Vaccine Evaluation and Study (ECVES): bead set coated with polysaccharide and monoclonal antibody pool were used in one multiplex inhibition-type immunoassay and 2 bead sets coated DNA probe and 2 primer pools were used in two multiplex PCR-based assays. After multibead serotyping assay was set up, 75 test samples of pneumococci were analyzed whether ECVES is able to identify serotype correctly. After confirming the performance, serotyping assay was applied to identify serotypes of 528 clinical isolates of pneumococci collected from 3 different hospitals. RESULTS: After establishment of the multibead pneumococcal serotyping assay system at ECVES, 75 test samples were analyzed. There was no discrepancy of serotypes of 75 test samples between the results assigned at UAB and those at ECVES. The serotypes of 528 pneumococci isolated from patients or healthy subjects were determined in 94.3% of isolates (498/528). CONCLUSIONS: The multibead pneumococcal serotyping assay can be successfully established in Korea. With this method, surveillance of serotypes of pneumococci isolated from patients as well as healthy subjects could be studied.

BACKGROUND: Invasive Streptococcus agalactiae (group B streptococcus, GBS) infection most commonly occurs in infants; however, cases of GBS infection in adults, particularly in the elderly with significant underlying diseases, are being increasingly reported. We analyzed the serotype specific opsonophagocytic antibodies (the major mechanism of protection against GBS) in infants, adults, and the elderly. METHODS: The opsonization indices (OIs) of antibodies against serotype Ia, Ib, II, III, and V GBS were studied in 89 infants, 35 adults (age, 30–50 years), and 62 elderly individuals (age, 65–85 years) according to the University of Alabama at Birmingham GBS opsonophagocytic killing assay protocol (www.vaccine.uab.edu). RESULTS: In infants, adults, and elderly groups respectively, geometric mean of OI against GBS serotype Ia were 3, 7, and 32; against GBS serotype Ib were 7, 242, and 252; against serotype II were 93, 363, and 676; against serotype III were 8, 212, and 609; and against serotype V were 4, 639, and 610. The seropositive rate (% of subjects with OI ≥ 4) increased significantly in older age group for all five serotypes. CONCLUSION: During infancy, only a limited proportion of infants have functional immunity against serotype Ia, Ib, II, III, and V GBS. Furthermore, a lack of opsonic activities against GBS observed in some adults and the elderly might predispose such individuals to the risk of invasive GBS infection. Epidemiological monitoring and development of suitable vaccine for these populations are needed.

Muscle-specific tyrosine-kinase-antibody-positive myasthenia gravis (MuSK-MG) has emerged as a distinct entity since 2001. This disease has been reported worldwide, but with varying rates among patients with generalized acetylcholine-receptor-antibody-negative MG. MuSK-MG was detected in approximately 37% of generalized acetylcholine receptor antibody-negative MG. MuSK-MG patients were predominantly female with more prominent facial and bulbar involvement and more frequent crises. Disease onset tended to be earlier. Patients tended to have a relatively poor edrophonium response but showed prominent decrement in the repetitive nerve stimulation test in the facial muscles. Patients were more likely to display poor tolerance of, or a lack of improvement with, anticholinesterase agents. Somewhat better response was observed with steroids and plasma exchange. Most were managed successfully with aggressive immunomodulatory therapies, although a higher proportion of MuSK-MG patients had a refractory course when compared with other forms of generalized MG. I present here an up-to-date overview on MuSK-MG based on our experience at the University of Alabama at Birmingham and the existing literature.

PURPOSE: Newborn screening (NBS) methods to detect congenital hypothyroidism (CH) vary regarding whether total thyroxine (T4), thyroid stimulating hormone (TSH), or both are measured. Neonates with low T4 and normal or low TSH (lowT4/TSH) may only be detected by T4-inclusive methods or age-dependent repeat screens. Premature neonates and those with pituitary-hypothalamic disorders frequently manifest lowT4/TSH.METHODS: This is a retrospective case-study of newborns who were screen-positive for lowT4/TSH in Alabama in 2009–2016 using a combined T4 and TSH method and 2 routine NBS. The clinical, laboratory, and final diagnosis after 3 years were determined.RESULTS: Over 8 years, 225 infants were referred to our institution for evaluation and treatment of CH. Twelve infants were screen-positive for lowT4/TSH by first or second NBS. Four of the 12 infants had permanent CH (30%): 2 with primary and 2 with central etiologies. One infant with moderately severe central CH was only detected by the routine second NBS. Six of 7 premature infants had elevated TSH on serum confirmation labs consistent with a delay in hypothalamic-pituitary maturation, yet 2 of these patients were later established to have permanent primary CH. While most cases of lowT4/TSH resolved by 3 years of age, several neonates had extended periods of moderate to severe hypothyroxinemia prior to detection and treatment.CONCLUSION: One third of the infants with lowT4/TSH on NBS in this study had permanent CH. These results emphasize the importance of T4-based assay methods, subsequent (repeat) screens and long-term follow-up in the management of neonates with lowT4/TSH on newborn screen.

PURPOSE: A knowledge gap exists between general physicians and specialists in diagnosing and managing Alzheimer disease (AD). This gap is concerning due to the estimated rise in prevalence of AD and cost to the health care system. Medical school is a viable avenue to decrease the gap, educating future physicians before they specialize. The purpose of this study was to assess the knowledge level of students in their first and final years of medical school. METHODS: Fourteen participating United States medical schools used e-mail student rosters to distribute an online survey of a quantitative cross-sectional assessment of knowledge about AD; 343 students participated. Knowledge was measured using the 12-item University of Alabama at Birmingham AD Knowledge Test for Health Professionals. General linear models were used to examine the effect of demographic variables and previous experience with AD on knowledge scores. RESULTS: Only 2.5% of first year and 68.0% of final year students correctly scored ten or more items on the knowledge scale. Personal experience with AD predicted higher knowledge scores in final year students (P=0.027). CONCLUSION: Knowledge deficiencies were common in final year medical students. Future studies to identify and evaluate the efficacy of AD education programs in medical schools are warranted. Identifying and disseminating effective programs may help close the knowledge gap.

PURPOSE: This study was to examine occupational therapy (OT) students' attitudes toward rehabilitating inmates and validate an instrument used to measure their attitudes. METHODS: OT students (n=128) from one university in Alabama, United States, completed an online survey exploring their attitudes toward rehabilitating inmates, which was assessed using the Rehabilitation Orientation Scale (ROS), a 7-point scale. Dimensional structure, internal consistency reliability, construct validity, and relations to other variables of the ROS was evaluated using factor analyses, Cronbach's alpha, known-groups method, and univariable correlations, respectively. RESULTS: Unidimensionality of the ROS was confirmed with an alpha coefficient of 0.90. The mean ROS score of the respondents was 5.1; a score toward 7 indicated a more supportive attitude. About 60% of the respondents reported supportive attitudes (i.e., an ROS score ≥5). Respondents' ROS scores were significantly higher than those of the public and criminal justice professionals. Female students reported a more supportive attitude than males. Multiple regression analysis indicated that respondents' consideration of working in prison settings after graduation and their perception that OT has a role in prison settings were significantly associated with support for rehabilitating inmates, after controlling for gender and an acquaintance with someone who has been incarcerated. CONCLUSION: Results indicated that the ROS demonstrated adequate psychometric properties as it applied to this population. The majority of respondents reported supportive attitudes toward rehabilitating inmates. Consideration of working in prison settings after graduation and the perception that OT has a role in prison settings were 2 independent factors associated with respondents' attitudes toward rehabilitating inmates.

The Tuskegee Study of Untreated Syphilis in the Negro Male was an observational study on African-American males in Tuskegee, Alabama between 1932 and 1972. The U. S. Public Health Service ran this study on more than 300 people without notifying the participants about their disease nor treating them even after the introduction of penicillin. The study included recording the progress of disease and performing an autopsy on the deaths. This paper explores historical backgrounds enabled this infamous study, and discusses three driving forces behind the Tuskegee Study. First, it is important to understand that the Public Health Service was established in the U. S. Surgeon General's office and was operated as a military organization. Amidst the development of an imperial agenda of the U.S. in the late 19th and early 20th centuries, the PHS was responsible for protecting hygiene and the superiority of “the American race” against infectious foreign elements from the borders. The U.S. Army's experience of medical experiments in colonies and abroad was imported back to the country and formed a crucial part of the attitude and philosophy on public health. Secondly, the growing influence of eugenics and racial pathology at the time reinforced discriminative views on minorities. Progressivism was realized in the form of domestic reform and imperial pursuit at the same time. Major medical journals argued that blacks were inclined to have certain defects, especially sexually transmitted diseases like syphilis, because of their prodigal behavior and lack of hygiene. This kind of racial ideas were shared by the PHS officials who were in charge of the Tuskegee Study. Lastly, the PHS officials believed in continuing the experiment regardless of various social changes. They considered that black participants were not only poor but also ignorant of and even unwilling to undergo the treatment. When the exposure of the experiment led to the Senate investigation in 1973, the participating doctors of the PHS maintained that their study offered valuable contribution to the medical research. This paper argues that the combination of the efficiency of military medicine, progressive and imperial racial ideology, and discrimination on African-Americans resulted in the Tuskegee Syphilis Experiment.
