Potential Indicators of Intestinal Necrosis in Portal Venous Gas: A Case Report of an 82-Year-Old Woman on Long-Term Hemodialysis with Ascites and Pneumatosis Coli.

BACKGROUND Several factors have been reported as possible predictors of intestinal necrosis in patients with portal venous gas (PVG). We describe potential indicators of intestinal necrosis in PVG identified by contrasting 3 episodes of PVG in a patient on hemodialysis against previously verified factors. CASE REPORT An 82-year-old woman undergoing hemodialysis was admitted to our hospital thrice for acute abdominal pain. On first admission, she was alert, with a body temperature of 36.3°C, blood pressure (BP) of 125/53 mmHg, pulse rate of 60/min, respiratory rate of 18/min, and 100% oxygen saturation on room air. Computed tomography (CT) revealed PVG, intestinal distension, poor bowel wall enhancement, bubble-like pneumatosis in the intestinal wall, and minimal ascites. PVG caused by intestinal ischemia was diagnosed, and she recovered after bowel rest and hydration. Three months later, she had a second episode of abdominal pain. BP was 115/56 mmHg. CT revealed PVG and a slight accumulation of ascites, without pneumatosis in the intestinal wall. She again recovered after conservative measures. Ten months later, the patient experienced a third episode of abdominal pain, with BP of 107/52 mmHg. CT imaging indicated PVG, considerable ascites, and linear pneumatosis of the intestinal walls. Despite receiving conservative treatment, the patient died. CONCLUSIONS A large accumulation of ascites and linear pneumatosis in the intestinal walls could be potential indicators of intestinal necrosis in patients with PVG caused by intestinal ischemia. As previously reported, hypotension was further confirmed to be a reliable predictor of intestinal necrosis.

Negative association between loneliness and healthy state among rural residents in Japan: a cross-sectional single region population-based survey.

Objective: Loneliness is an important health problem in rural areas of Japan because of its ageing and declining population. Therefore, we investigated the association between loneliness and health. Materials and Methods: Self-administered questionnaires were distributed to rural adult residents. The Japanese 3-item versions of the UCLA Loneliness Scale, self-rated health (SRH), and objective health status (whether the respondents had a physical and/or mental illness) were used. We defined a UCLA score of four points or more as loneliness, an SRH of four points or more as a subjective healthy state, and no physical or mental illness as an objective healthy state. The association was adjusted for sociodemographic data, lifestyle habits, and isolation risk using logistic regression analysis. Results: The five-year population decline rate in the target areas was 10.2 to 12.3%. Of the 2,700 participants, there were 1,211 male and 1,489 female respondents, with an average age of 65.4 years. Moreover, 358 (13.6%) were living alone, and 829 (31.5%) were living in couple-only households. Among the participants, 1,395 (53.2%) experienced loneliness, 1,751 (65.7%) had good self-rated health, and 1,587 (60.8%) had objective health status. Loneliness was negatively associated with good SRH (OR=0.56, CI=0.45-0.70) and objective health status (OR=0.57, CI=0.46-0.71) after adjusting for sociodemographic data, lifestyle habits, and the risk of isolation. Statistically significant confounding factors for subjective and/or objective health status were employment, not smoking, obesity, exercise, having a family doctor, having an above-average number of teeth, and the ability to leave home. Conclusion: In an ageing and declining population, loneliness is an independent factor affecting the health status of rural residents and is not limited to older adults. Therefore, measures to reduce it are needed.

Heidenhain Variant of Sporadic Creutzfeldt-Jakob Disease with a Variety of Visual Symptoms: A Case Report with Autopsy Study.

BACKGROUND Sporadic Creutzfeldt-Jakob disease (sCJD) is a fatal disease caused by the change of prion protein (PrP). Affected patients present with rapidly progressive cognitive dysfunction, myoclonus, or akinetic mutism. Diagnosing the Heidenhain variant of sCJD, which initially causes various visual symptoms, can be particularly difficult. CASE REPORT A 72-year-old woman presented with a 2- to 3-month history of photophobia, blurring vision in both eyes. Seven days previously, she showed visual impairment of 20/2000 in both eyes. Left homonymous hemianopia and restricted downward movement of the left eye were observed with an intact pupillary light reflex and normal fundoscopy. On admission, her visual acuity was light perception. Cranial magnetic resonance imaging revealed no abnormality, and electroencephalography showed no periodic synchronous discharges. Cerebrospinal fluid examination on the sixth hospital day revealed tau and 14-3-3 protein with a positive result of real-time quaking-induced conversion. She thereafter developed myoclonus and akinetic mutism and died. Autopsy revealed thinning and spongiform change of the cerebral cortex of the right occipital lobe. Immunostaining showed synaptic-type deposits of abnormal PrP and hypertrophic astrocytes. Consequently, she was diagnosed with the Heidenhain variant of sCJD with both methionine/methionine type 1 and type 2 cortical form based on the western blot of cerebral tissue and PrP gene codon 129 polymorphism. CONCLUSIONS When a patient presents with various progressive visual symptoms, even without typical findings of electroencephalography or cranial magnetic resonance imaging, it is essential to suspect the Heidenhain variant of sCJD and perform appropriate cerebrospinal fluid tests.

Vulvar Paget's Disease Presenting with Fever and Left Inguinal and Peritoneal Lymphadenopathies.

BACKGROUND Asymptomatic vulvar Paget's disease is rare and commonly presents with vulvar eczema, erosions, or pruritus. The time from onset to diagnosis of vulvar Paget's disease tends to be rather long because of difficulty making a correct diagnosis owing to similar skin findings with eczema or patients' reluctance to undergo physical examination of their pubic area because of embarrassment. CASE REPORT A 55-year-old woman experienced recurrent episodes of fever for 10 months. Her primary care physician indicated inguinal lymphadenopathy 2 months prior to presentation at our hospital. Contrast-enhanced abdominal computed tomography revealed multiple intra-abdominal lymphadenopathies. With the failure of finding the primary lesion after biopsy, and with a diagnosis of metastatic carcinoma, she was referred to our hospital. On admission, she did not report having vulvar symptoms. As imaging studies revealed no primary lesions, we subsequently added immunostaining to the lymph node biopsy specimens, which suggested Paget's disease. We finally performed a vulvar physical examination and identified eczema. We performed a skin biopsy and histopathological examinations, which provided the final diagnosis of vulvar Paget's disease. CONCLUSIONS We experienced a case of vulvar Paget's disease presenting with inguinal and intraperitoneal lymphadenopathies, without a patient report of vulvar symptoms. When identifying lymphadenopathies, it is crucial to obtain a careful history and perform appropriate physical examinations, suspecting diseases of the vulva or perineum. In addition, immunostaining of lymph node biopsy specimens could be useful in making a correct diagnosis.

Diverticulitis in the sigmoid colon presenting with only lower anterior chest pain.

An 80-year-old man who presented with only lower anterior chest pain was diagnosed as sigmoid colon diverticulitis. His chest pain was considered to be referred pain from a disease at sigmoid colon, which should be suspected when other major causes of chest pain are excluded.

Relapse of acute myocarditis associated with Campylobacter jejuni enterocolitis.

Chest pain in a patient with Campylobacter jejuni infection may be caused by acute myocarditis associated with C jejuni infection. Because the myocarditis associated with C jejuni infection can recur, careful follow-up is required even after the improvement of chest pain and electrocardiography abnormalities.

The lambda sign in gallium-67 scintigraphy is a useful clue to the early diagnosis of sarcoidosis.

A 40-year-old man with bilateral hilar lymphadenopathy in chest X-ray and the λ-sign in gallium-67 scintigraphy was subsequently diagnosed with systemic sarcoidosis according to the findings of bronchoalveolar lavage and histopathological examinations of transbronchial lung biopsies. Identifying the λ-sign could be a valuable clue to the early diagnosis of sarcoidosis.

Traumatic bilateral fourth nerve palsy: Double vision induced by downward gaze after head injury.

Clinicians should be alert to traumatic fourth nerve palsy in patients with double vision after head injury. In most cases with traumatic fourth nerve palsy, the imaging tests fail to show abnormal findings. In the cases of bilateral superior oblique paresis, the sensitivity of Bielschowsky head-tilt test is 40%.

Mobile medical services and experiential learning in community-based clinical clerkships enhancing medical students' positive perceptions of community healthcare.

Objective: Previous studies have investigated medical students' interest in family medicine, as well as their intentions to work in rural areas after taking part in community-based clinical clerkships. Community-based clerkships are designed to teach medical students community healthcare and to increase the number of physicians working in rural communities following their graduation. However, few studies have examined which clerkship experiences, specifically, enhance medical students' positive perceptions on community healthcare. This study aimed to examine the association between experiential learning in community-based clerkships and students' positive perceptions on community healthcare. Patients and Methods: From 2015 to 2017, we conducted a questionnaire survey of 290 final year medical students, before and after completion of their community-based clerkships. The survey asked the students about their perceptions (categorized into "Worthwhile" and "Confident") of community healthcare and experiential learning during their clerkships. We assessed 13 medical learning areas involving healthcare, medical care, welfare, and nursing care practice. Multivariable logistic regression was used to evaluate the factors associated with positive student perceptions. Results: Of the 290 students, 265 (91.3%) completed both the pre- and post-questionnaires. Of these, 124 (46.8%) were female, 67 (25.2%) were from small towns (of <100,000 people), and 87 (32.8%) selected clinical clerkships within depopulated areas. A total of 205 (73.3%) students reported positive perceptions on community healthcare. There was a significant association discovered between students' positive perceptions on community-based healthcare and them taking part in experiential learning in mobile medical services (43 [16.2%] students experienced mobile medical services-adjusted odds ratio 6.65, 95%, confidence intervals 1.67-26.4, p = 0.007). Conclusion: Medical students' positive perceptions on community healthcare were discovered to be associated with them taking part in experiential learning in mobile medical services during their community-based clerkships.

Do you know otitis media with ANCA-Associated Vasculitis (OMAAV)?

Hearing loss is often the only symptom of OMAAV at initial presentation, thus making early diagnosis difficult. We present OMAAV in a 70-year-old woman with hearing loss and dry cough. Otoscopy showed otitis media with effusion. Audiometry showed mixed hearing loss, especially in the right ear. Serum myeloperoxidase antineutrophil cytoplasmic antibody was positive. Image analyses showed lung lesion and interstitial pneumonia, while bronchoscopy showed possible microscopic polyangiitis. After starting and tapering prednisolone, respiratory and otologic symptoms improved. When examining patients with acute otologic symptoms and suspected lung and/or renal disease, OMAAV should be included in differential diagnosis.

Change of Oral to Topical Corticosteroid Therapy Exacerbated Glucose Tolerance in a Patient with Plaque Psoriasis.

BACKGROUND Psoriasis is known as the most frequent disease treated by long-term topical steroids. It is also known that patients with thick, chronic plaques require the highest potency topical steroids. However, the treatment is limited to up to four weeks due to risk of systemic absorption. CASE REPORT An 80-year-old man was diagnosed with type 2 diabetes 16 years before, and was being administered insulin combined with alpha glucosidase inhibitor. He was diagnosed with plaque psoriasis and his oral steroid treatment was switched to topical steroid treatment due to lack of improvement and poorly controlled blood glucose level. The hypoglycemic events improved after the psoriatic lesions improved. CONCLUSIONS Control of blood glucose level is difficult at the very beginning of topical steroid treatment for psoriasis especially if a patient is receiving insulin treatment. Intense monitoring of blood glucose level during initiation of topical steroid treatment is necessary to prevent unfavorable complications.
