Abstract Anorexia nervosa (AN) is occasionally complicated with hypoglycemic coma, which may cause sudden death by unknown mechanisms. We present the case of a 36-year-old woman with recurrent comas and a nineteen-year history of AN. She was found in a coma with remarkable hypoglycemia (28 mg/dL). Her BMI was 11.1 kg/m2. Endocrine workup revealed extremely low serum levels of glucagon, IGF-I and insulin. Asymptomatic hypoglycemia occurred with liver injury in the refeeding process. An aberrant glucose metabolism due to liver damage might have been involved in her susceptibility to hypoglycemia. This case suggests a possible mechanism of hypoglycemic coma in AN.

Abstract Research suggests that the fundamental concepts of epidemiology cannot be sufficiently learned in traditional lectures, and interactive learning is necessary. However, few studies have investigated interactive epidemiology education in general, or peer instruction (PI) in particular. This study investigated the effect of PI. Study par-ticipants were fourth-year medical students. The attitude of participants in regard to PI learning was examined in a non-PI and a PI group. The Survey of Attitudes Toward Statistics (SATS) (containing six sub-categories) was conducted as a learning-attitudes index. The pre- and post-lecture scores were compared between the non-PI and PI groups using double robust (DR) estimation. The non-PI and PI groups consisted of 20 and 121 student participants, respectively. In DR estimation, affect exhibited the lowest SATS score changes, at −0.51 (95% confidence interval −0.78 to −0.24; p-value < 0.001), whereas effort exhibited the highest score changes of 0.01 (95% confidence interval −0.30 to 0.32; p-value = 0.952). The epidemiology lecture with PI did not increase the SATS scores. This might be due to issues related to the experimental design. Further research investigating the effects of interactive epidemiology education, it will be necessary to develop tools for assessing the learning of epidemiological concepts and to improve the research design.

Abstract Influenza potentially has a high mortality rate when it affects the elderly. We aimed to examine the differences in clinical manifestations in patients with influenza according to their age. This multicenter prospective study was performed in six medical institutions in Okayama and Kagawa prefectures (Japan). Between December 1, 2019 and March 31, 2020, we collected data on adult patients diagnosed with influenza type A, who were strat-ified into younger (20-49 years), middle-aged (50-64 years), and older groups (≥ 65 years). We compared the presence or absence of fever, respiratory symptoms, and extrapulmonary symptoms according to age group. In total, 203 patients (113, younger; 51, middle-aged; and 39, older) were eligible for the analysis. The maxi-mum body temperature and temperature at first physician visit in the older group were significantly lower than those in the younger group. The incidence of respiratory symptoms was not different among the three groups. Chills, muscle pain, and arthralgia as systemic symptoms were noted significantly more frequently in the younger (80.9%) and middle-aged (75.5%) groups than in the older group (51.3%) (p = 0.002). Fever and sys-temic symptoms were less likely to appear in older patients, possibly resulting in the delaying of hospital visits among older adults.

Abstract Primary Sjögren’s syndrome (SS) is an autoimmune disease that usually affects the exocrine glands in mid-dle-aged women. Fifteen percent of SS patients experience severe systemic extraglandular complications, and pleuritis is one of the rare complications of SS. We report the case of an elderly Japanese man who initially pre-sented with a prolonged fever and chest pain and was finally diagnosed with primary SS-associated pleuritis. Of the nine reported cases of primary SS that initially presented with pleuritis, up to six cases were elderly males. This case highlights the complication of pleuritis among elderly males with primary SS.

Abstract Ebola virus disease (EVD) is a highly contagious and fatal disease in humans. Healthcare providers (HCPs) are often at the frontline of epidemics and can thus be in jeopardy of contracting EVD. Sudan is at a great risk of an EVD outbreak, as it borders countries that experienced EVD outbreaks. It is therefore imperative in Sudan to assess the HCPs’ awareness and knowledge, attitude, and practice (KAP) about EVD for its control and man-agement and for preparedness. A KAP survey was conducted among 387 HCPs (physicians, nurses and labora-tory technicians) in the three main tertiary hospitals in Khartoum, Sudan. The majority of the survey respon-dents (54.5%) were females, < 30 years old (76.3%), and single (77.4%). Most (94%) had heard about EVD, 62% from classical media. Only 14% had received education or training regarding EVD. About 40% reported being adherent to universal precautions and 72% were willing to deal with EVD patients under safety precau-tions. Only 10% knew of any available standard national guidelines for EVD. Nearly half of the HCPs (47%) rated the potential risk of an EVD outbreak in Sudan as high, and 52% rated health authorities’ effort against it as weak. These findings revealed the HCPs’ insufficient knowledge of EVD and the necessary universal precau-tions. This lack of knowledge would negatively affect the HCPs’ preparedness toward any potential EVD out-break. There is a dire need to train HCPs in Sudan on the management of EVD, including preventive and con-trol measures.

Abstract Instances of traumatic brain injury (TBI) in the elderly have been increasing along with the aging of popula-tions. In the present study, we examined the effect of aging on long-term multidisciplinary in-patient rehabili-tation efficacy after TBI. Sixty-three patients with physical and cognitive impairments after TBI were enrolled in this study. Patients were divided into 4 age groups (≤ 24, 25-44, 45-64, ≥ 65 years) and the clinical charac-teristics and rehabilitation efficacy of each age group were determined. Functional disability was evaluated using motor and cognitive Functional Independence Measure (FIM) scores. Rehabilitation efficacy was assessed by FIM gains during rehabilitation and compared among the groups. There were no statistically significant dif-ferences in motor and cognitive FIM gains among the age groups. However, cognitive FIM gain was limited in a subset of ≥ 65 patients, and initial cognitive measures could not predict cognitive FIM improvement. These results indicate that chronological age is insufficient to accurately predict rehabilitation efficacy in older TBI patients, and that such patients should be considered candidates for intensive rehabilitation programs based on these results. Accurate prognostication of rehabilitation efficacy with continuing data collection is important when using rehabilitation resources for older TBI patients.

Abstract Epiretinal membrane (ERM) is a common retinal disease characterized by cellular proliferation and metaplasia that lead to the formation of a pathological fibrocellular membrane immediately superjacent to the inner retinal surface. The vast majority of ERMs are considered idiopathic. However, ERM formation can result from various primary intraocular diseases, including retinal breaks and detachment, retinal vascular diseases, and vitreoretinal inflammatory conditions. Although ERMs are generally asymptomatic or cause mild metamorphopsia and/or a modest decrease in visual acuity, some can cause severe macular distortion and macular edema, resulting in significantly impaired function. Surgical removal of ERM is the only treatment, and improvements in vitrectomy systems have enabled less invasive treatment. However, there are currently no standardized criteria for ERM surgery, and the indications for surgery are determined from the patient’s subjective symptoms. Another problem with ERM surgery is that not all patients show satisfactory postoperative recovery of visual function. Thus, further research is needed to determine the criteria for ERM surgery and methods to improve the postoperative prognosis.
