The Association Between the Frequency of Agriculture and Control of Chronic Diseases Among Regular Patients in Rural Community Hospitals: A Cross-Sectional Study.

Introduction The importance of exercise in chronic disease management among older people is paramount, especially as the global population ages and the prevalence of chronic diseases such as cardiovascular disease, diabetes, and arthritis increases. Regular physical activity enhances cardiovascular health, improves metabolic function, and alleviates symptoms of musculoskeletal disorders. As a form of exercise, agriculture provides physical and mental benefits for older adults. However, its impact on chronic disease management can be mixed, as the physical demands and potential stress associated with agricultural tasks can exacerbate certain health conditions. Method This cross-sectional study was conducted in Unnan City, a rural area in Japan, focusing on residents aged 40 and older who regularly visited Unnan City Hospital. Data were collected from 647 participants between September 1, 2023, and November 31, 2023, through questionnaires and electronic medical records. The primary outcome was the management of chronic diseases, assessed through hypertension, dyslipidemia, diabetes mellitus, and obesity control. Participants reported their frequency of agricultural activities, exercise, eating habits, and sleep. Statistical analyses included t-tests, Mann-Whitney U tests, and multivariate logistic regression models. Results Participants engaging frequently in agricultural activities were younger, had better hypertension control, and reported healthier eating habits and sleep patterns. Frequent agricultural activities were associated with a lower likelihood of hypertension (OR: 0.62, 95% CI: 0.39-0.97, p = 0.034). Older age (≥75 years), higher BMI (≥25), and a Charlson comorbidity index (CCI) score of ≥5 were significantly associated with hypertension. No significant associations were found between hypertension and other health-related variables such as healthy eating, adequate sleep, and regular exercise. Conclusion The study highlights the potential benefits of agricultural activities in managing chronic diseases, particularly hypertension, among older adults. However, the physical demands and possible social isolation associated with agricultural tasks require a nuanced approach to promoting these activities. Tailored, community-based agricultural programs that foster social interaction and support can enhance physical and mental health benefits. Future research should focus on longitudinal studies to confirm these findings and explore the long-term health outcomes of agricultural activities in diverse contexts.

Drainage by Ovarian Incision for the Treatment of Massive Ovarian Edema Torsion During Pregnancy.

Massive ovarian edema (MOE) is a rare benign condition presenting as unilateral ovarian enlargement with stromal edema, and only a limited number of MOE cases during pregnancy have been reported. MOE is often complicated by ovarian torsion, which requires detorsion. Although the diagnosis of MOE can be made using ultrasound and magnetic resonance imaging, its rarity makes diagnosis difficult, usually leading to overtreatment. Preserving the ovary in the treatment of MOE torsion is essential, and consideration of oophoropexy after detorsion is often reported. However, fixing an enlarged ovary to the pelvic wall in the limited space of the pelvis is challenging. Herein, we present a case of MOE of the right ovary diagnosed at the fifth week of gestation after ovulation induced by clomiphene citrate. Torsion of the ovary occurred in the seventh week. We achieved preservation of the ovary through laparoscopic surgery with detorsion and drainage by making a small incision to the enlarged ovary, resulting in an immediate size reduction. There was no recurrence of torsion or MOE throughout the pregnancy, and the patient gave birth in the 39th week of gestation. This is the third reported case of MOE after ovulation using clomiphene citrate, and it highlights the effectiveness of treatment with detorsion and a small incision of the ovary via laparoscopic surgery in patients with MOE torsion during pregnancy.

Linking Agricultural Activity Frequency to Loneliness in Rural Hospital Patients: A Cross-Sectional Study.

Introduction Agriculture is deeply woven into the fabric of rural life, influencing the economy, and the social and health dynamics of rural communities. While it offers physical and mental health benefits through regular physical activity and interaction with nature, the solitary nature of farming activities may also lead to social isolation. This study explores the complex relationship between the frequency of agricultural engagement and feelings of loneliness among rural inhabitants with chronic diseases, addressing a gap in the literature concerning the impact of agricultural practices on social well-being. Method A cross-sectional analysis was conducted among patients over 40 who frequented the general medicine department in Unnan City, a rural area of Japan. The study utilized the Japanese version of the University of California, Los Angeles (UCLA) Loneliness Scale to assess loneliness and collected data on agricultural activity frequency through questionnaires. Multivariate logistic regression analyses examined the association between agricultural activities and loneliness, controlling for demographic and health-related variables. Results Among 647 participants, higher frequencies of agricultural activities were significantly associated with increased loneliness, especially for individuals engaging in agriculture four to five times weekly or daily. Engaging in agricultural activities four to five times weekly and daily significantly increased the likelihood of higher loneliness levels, with odds ratios (OR) of 1.80 (p = 0.039) and 2.47 (p < 0.01), respectively, when compared to engagement less than once a week. Age emerged as an influential factor, with individuals aged 75 and older showing increased odds of experiencing higher loneliness (OR 1.56, p = 0.025). Conclusion The study underscores the dual nature of agricultural engagement in rural communities, highlighting its role in both supporting physical health and contributing to social isolation. These findings advocate for developing targeted interventions that mitigate loneliness among rural populations, suggesting the need for a balanced approach that encompasses social and healthcare strategies to enhance the overall well-being of individuals engaged in agriculture.

The Association Between Community Dialogue and Loneliness in Rural Japanese Communities: A Cross-Sectional Study.

Introduction This investigation explores the influence of community dialogue on loneliness within rural Japanese communities amidst the backdrop of globalization, urbanization, and technological shifts. Highlighting the significance of both informal and formal community dialogues, the study aims to bridge the gap in empirical evidence regarding the role of these interactions in enhancing social cohesion and mitigating loneliness, particularly in rural areas facing demographic changes and privacy concerns. Method A cross-sectional study was performed in Unnan City, Japan, targeting individuals over 40 who regularly visited a local rural hospital. The study employed the Japanese version of the University of California, Los Angeles (UCLA) Loneliness Scale and questionnaires regarding the frequency of community dialogue, alongside examining participants' health and demographic details from hospital records. Analysis methods included t-tests, Mann-Whitney U tests, and multivariate logistic regression to examine the association between community dialogue frequency and loneliness. Results Among the 647 respondents, the participants' mean age was 71.26 years, with a male rate of 46.3%. The multivariate logistic regression analysis revealed that higher frequencies of community dialogue significantly reduce the odds of experiencing loneliness. Specifically, compared to individuals with the least frequency of community dialogue, those with more frequent and most frequent dialogues were significantly more likely to report higher loneliness levels, with odds ratios of 2.62 (95% CI: 1.60-4.29, p<0.01) and 4.11 (95% CI: 2.47-6.85, p<0.01), respectively. Additionally, an increase in BMI was inversely related to loneliness (OR: 0.95, 95% CI: 0.91-0.99, p=0.023), and individuals with a higher comorbidity index (CCI≥5) showed a decreased likelihood of reporting higher loneliness (OR: 0.64, 95% CI: 0.43-0.96, p=0.031). Conclusion This study shows compelling evidence that more frequent community interactions are inversely associated with feelings of loneliness. These findings suggest that initiatives to increase community dialogue need a nuanced approach to mental health and social cohesion in rural settings. The research further reveals an intriguing relationship between body mass index, the severity of comorbidities, and loneliness, offering insights into the complex interplay between physical health and social well-being. The importance of this study lies in its potential to inform policies and programs designed to foster social connections respecting rural contexts, thereby addressing the challenge of loneliness in rural communities.

The Association Between Community Participation and Loneliness Among Patients in Rural Community Hospitals: A Cross-Sectional Study.

Introduction Loneliness among adults is a critical public health issue, particularly in rural areas where social isolation can be more pronounced. Understanding the factors that influence loneliness can guide the development of effective interventions. This study explores the impact of demographic, health-related, and social participation factors on loneliness among rural Japanese adults, focusing on the role of community participation. Method This cross-sectional study was conducted with rural Japanese adults who regularly visited rural community hospitals. Data were collected on participants' demographic characteristics, health status, and social participation and analyzed using a multivariate logistic regression model to identify factors associated with higher levels of loneliness. The covariates included age, sex, body mass index (BMI), chronic health conditions, and community participation. Results The study found that community participation had a significant negative association with loneliness, with an odds ratio (OR) of 0.46 (p < 0.01), indicating that individuals engaged in community activities were substantially less likely to experience higher levels of loneliness. Higher BMI was associated with lower odds of loneliness (OR = 0.93, p < 0.02), suggesting a protective effect against loneliness. Conclusion The findings highlight the paramount importance of community engagement in mitigating loneliness among rural Japanese adults. The inverse relationship between BMI and loneliness suggests that BMI and social participation influence loneliness. These insights underscore the need for comprehensive interventions that promote community participation and address the multifaceted nature of loneliness. Future research should further explore the mechanisms through which community engagement and BMI impact loneliness to develop targeted strategies for improving the well-being of rural adults.

Ureter Injury in Laparoscopic Para-Aortic Lymphadenectomy for Endometrial Cancer by the Transperitoneal Approach.

The patient was 66 years old, had three pregnancies and two deliveries, and was menopausal at the age of 51. She had irregular bleeding and was found to have a chicken-egg-sized uterus and a thickened endometrium (23 mm). She underwent laparoscopic surgery for uterine endometrial cancer (endometrioid carcinoma G1, stage IB). Laparoscopic simple hysterectomy, bilateral adnexectomy, pelvic lymph node dissection, para-aortic lymph node dissection, and partial omentectomy were performed using the transperitoneal approach (TPA). The patient was obese, with a height of 148 cm, a weight of 68 kg, and a body mass index of 31 kg/m2. She had a large amount of visceral fat, which made it difficult to expand the surgical field during para-aortic lymph node dissection. A laparoscopic fan retractor (EndoRetract II, Medtronic) was used to lift the intestinal tracts and expand the field of view. It broke the fat around the left kidney, and the exposed left ureter was heat-damaged using a vessel sealing device (LigaSure, Medtronic). Postoperatively, a left ureteral stent was placed, and continuous urine draining into the retroperitoneum was performed. To prevent injury to the left ureter, the left ovarian vein branching from the left renal vein should be exposed as a landmark before the left ureter running parallel to it is isolated. It is essential that the fat around the left kidney is not broken during this operation. The left iliopsoas muscle should be exposed, and using this as a base, the left ovarian vein, left ureter, and left perirenal fat should be compressed and moved to the left side using a fan retractor to ensure a safe operation.

Ureter Injury in Total Laparoscopic Hysterectomy.

Objective: To identify surgical manipulations that caused ureter injury during total laparoscopic hysterectomy (TLH) and evaluate the surgical manipulations to identify ways to prevent such injury. Patients and Methods. This single-center, cross-sectional study included 1135 cases of TLH performed for benign diseases from January 2009 to December 2021. Seven cases (0.6%) that needed ureteral stent placement intra- or postoperatively for ureter injury were included. We identified the surgical manipulations that caused ureter injury from surgical videos. Results: Two cases had adhesions around the bladder pillar, and the ureter sustained a thermal injury during the cardinal ligament transection. One case had severe endometriosis, and the ureter was bluntly damaged when the adhesion was released. In one case, the ureter was thermally damaged during bipolar hemostasis for uterine artery bleeding. In two cases, the obliterated umbilical artery was mistaken for the ureter, and the real ureter was injured. In one case, ureteral peristalsis was inhibited by a pelvic abscess caused by postoperative infection. Conclusion: To prevent ureter injury during TLH, the ureter should be isolated in case of severe adhesion. Moreover, the following could be considered: (1) expand Okabayashi's pararectal space lateral to the uterosacral ligament, (2) perform dissection sharply using a monopolar or scissors forceps when releasing adhesion, (3) clarify the anatomy around the ureter for cases needing hemostasis, (4) repeatedly confirm the ureter with its peristalsis even after its isolation, (5) for severe adhesion cases, reduce infection risk by drain placement and administering antibiotics, and (6) use a delineator cup.

The Usefulness of Magnetic Resonance Imaging in the Management of Acute Phlegmonous Esophagitis.

Acute phlegmonous esophagitis is a rare life-threatening disease that often requires surgical intervention in case of complications, including esophageal abscess, perforation, or mediastinitis. We present a case of acute phlegmonous esophagitis, in which magnetic resonance imaging (MRI) proved useful in planning the treatment strategy. An 89-year-old woman was admitted to the emergency department with painful swallowing and respiratory distress. She was diagnosed with acute phlegmonous esophagitis and a hypopharyngeal abscess based on computed tomography (CT) findings. However, there was a discrepancy between the clinical course and CT findings. Given the improvement of the patient's condition with conservative treatment with ampicillin/sulbactam, the CT findings suggested an apparent abscess due to increased esophageal wall thickness. However, MR diffusion-weighted images showed a slightly high-intensity signal, suggesting that the enlargement was due to edema rather than an abscess. The patient recovered successfully following conservative treatment. Thus, our findings demonstrate the utility of MRI in the treatment planning of acute phlegmonous esophagitis, especially in cases with unreliable contrast-enhanced CT findings. However, future studies are warranted to explore the utility of MRI in the management of such cases.

Laparoscopic intervention for solid pelvic tumours in Mayer-Rokitansky-Küster-Hauser syndrome: a case of bilateral uterine adenomyomas of the rudimentary uterus.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, a condition caused by Müllerian anomalies, is characterised by congenital vaginal aplasia and a rudimentary uterus. Case reports concerning uterine fibroids associated with MRKH syndrome are limited, and differentiating between uterine fibroids and ovarian solid tumours prior to surgical intervention is often challenging. Here, we present the case of a patient with MRKH syndrome and asymptomatic bilateral pelvic solid tumours located close to both ovaries. Based on intraoperative and histopathological findings, the tumours were diagnosed as adenomyomas of the rudimentary uterus. This is the first reported case of a uterine adenomyoma associated with MRKH syndrome. Moreover, our report highlights the fact that diagnostic laparoscopy is a valuable method to evaluate pelvic tumours in MRKH syndrome.

Dystextia and dystypia due to phonological errors after ischemic stroke: a case report in a Japanese patient.

A 69-year-old Japanese male presented with acute dystextia and dystypia, defined as texting and typing impairments, respectively. His text input speed decreased due to a phonologically incorrect kana flick input on his smartphone. Additionally, dystypia occurred due to phonemic paragraphia of Romaji. Brain MRI revealed a new left lenticulostriate infarction sparing the cerebral cortex. SPECT showed reduced cerebral blood flow in the left inferior precentral frontal gyrus as well as in the infarction area. It was concluded that his abnormal phonological processes resulted from hypoperfusion in the left inferior precentral gyrus that is assumed to be an endpoint of the arcuate fasciculus.

A randomized, double-blind, placebo-controlled, dose-escalating phase I trial to evaluate safety and immunogenicity of a plant-produced, bivalent, recombinant norovirus-like particle vaccine.

Noroviruses (NoV) are the leading cause of epidemic acute gastroenteritis in humans worldwide and a safe and effective vaccine is needed. Here, a phase I, double-blind, placebo-controlled clinical trial was performed in 60 healthy adults, 18 to 40 years old. Safety (primary objective) and immunogenicity (secondary and exploratory objectives) of a bivalent (GI.4 and GII.4), plant-produced, virus-like particle (VLP), NoV vaccine candidate formulation were investigated at two dose levels (50 µg + 50 µg and 150 µg + 150 µg) without adjuvant. Overall, 13 subjects (65.0%) in the 50 µg group, 16 subjects (80.0%) in the 150 µg group, and 14 subjects (70.0%) in the placebo group reported at least 1 solicited local or general symptom during the 7-day post-vaccination periods following each dose. Severe solicited adverse events (AEs) were rare (2 events in the 50 µg group). A total of 8 subjects (40.0%) in each group reported at least one unsolicited AE during the 28-day post-vaccination periods. Immunogenicity was assessed on days 1, 8, 29, 57, 183 and 365. All subjects were pre-exposed to norovirus as indicated by baseline levels of the different immunological parameters examined. Vaccine-specific humoral and cellular immune responses increased after the first dose but did not rise further after the second vaccination. Increased GI.4- and GII.4-specific IgG titers persisted until day 365. The vaccine elicited cross-reactive IgG antibodies against non-vaccine NoV VLPs, which was more pronounced for NoV strains of the same genotype as the GII.4 vaccine strain than for non-vaccine genotypes. Significant blocking anti-GI.4 and anti-GII.4 VLP titers were triggered in both dose groups. Lymphoproliferation assays revealed strong cell-mediated immune responses that persisted until day 365. In conclusion, both dose levels were safe and well-tolerated, and no higher incidence of AEs was observed in the higher dose group. The data show that a single dose of the vaccine formulated at 50 µg of each VLP is sufficient to reach a peak immune response after 8 to 28 days. The results of this Phase I study warrant further evaluation of the non-adjuvanted vaccine candidate.

Gastrointestinal Stromal Tumor with Repeated Multiple Cerebral Infarction Mimicking Ovarian Cancer with Trousseau's Syndrome.

We report a case of gastrointestinal stromal tumor (GIST) with repeated multiple cerebral infarctions mimicking ovarian cancer. A 79-year-old postmenopausal woman had multiple cerebral infarctions with a giant pelvic tumor detected by computed tomography. Ovarian cancer with Trousseau's syndrome was suspected. Through laparoscopic biopsy on the tumor surface, she was diagnosed with left ovarian fibrosarcoma; although, the abdominal cavity could not be observed appropriately. Ovarian fibrosarcoma is an extremely rare tumor and still has no adequate treatment strategy. Complete resection was planned. The tumor was extremely fragile, and gelatinous that it easily bled. Meanwhile, the uterus and bilateral ovaries and fallopian tubes were all normal. The tumor invaded only the peritoneum near the left sacral uterine ligament and sigmoid colon, with no peritoneal dissemination. To completely remove the tumor, we performed total hysterectomy with bilateral salpingo-oophorectomy and omentectomy and sigmoidal and rectal resection with colostomy. Despite resuming her anticoagulant therapy on postoperative day 4, she had recurrent multiple strokes. On histopathological examination, tumor showed spindle cell proliferation with severe atypia, increased mitotic activity, and widespread necrosis. Immunohistochemical studies showed positive staining for c-kit, CD34, and DOG1. Thus, she was diagnosed with GIST. This case was rare and highly malignant, with a high risk of recurrence of GIST because of a giant ruptured tumor that had a mitotic activity of 36/10 high-power fields from the sigmoid colon. Multiple cerebral infarctions mimicking ovarian cancer recurred. Therefore, preoperative diagnosis of an atypical GIST was extremely difficult.

A case of problems in supporting a patient after Y-chromosome long arm microdeletion testing at a Japanese general hospital.

There are only few reports on the problems faced post-Y-chromosome microdeletion tests that decide the use of micro testicular sperm extraction. We report a case wherein we faced issues in supporting a patient post-testing. One patient with azoospermia factor c (AZFc) deletion gave birth to a baby boy, who could have inherited the AZFc deletion; however, we could not inform the young patient. Therefore, it is necessary to establish a post-testing support system for patients and infants.

Placental polyp with arteriovenous malformation treated with a gonadotoropin-releasing hormone antagonist.

A 35-year-old woman (gravida 1, para 0) underwent termination of pregnancy (ToP) at 12 weeks of gestation. One month after ToP, she experienced significant vaginal bleeding and the mass with blood flow was identified on imaging. The presence of a placental polyp with arteriovenous malformation (AVM) was suspected on transvaginal sonography and MRI. Since the bleeding had ceased when she visited our hospital, we decided to treat the placental polyp with AVM with gonadotropin-releasing hormone (GnRH) antagonist therapy instead of surgery. Two months after GnRH antagonist treatment, the mass and blood flow in the uterus disappeared. Menstruation resumed 1 month after the completion of treatment. In our case, we were able to successfully treat placental polyps with AVM using GnRH antagonist therapy.

Characteristics and outcomes of women with adenocarcinoma versus squamous cell carcinoma of the vulva: A Japanese Gynecologic Oncology Group study.

OBJECTIVE: Studies on vulvar adenocarcinoma are lacking. Thus, we aimed to compare the characteristics and survival outcomes between vulvar adenocarcinoma and squamous cell carcinoma (SCC). METHODS: This was a preplanned sub-analysis of a previously organized nationwide retrospective observational study in Japan conducted between 2001 and 2010 (JGOG-1075S). Surgically treated women with stage I-IV vulvar invasive adenocarcinoma were compared to those with SCC. Multivariable analysis was performed to identify patient and tumor characteristics related to adenocarcinoma. Inverse probability of treatment weighting was used to balance the background differences, and a Cox proportional hazards regression model was fitted to estimate the effect of the histological type on survival. RESULTS: Forty-eight women with adenocarcinoma were compared with 537 women with SCC. On multivariable analysis, women with adenocarcinoma were younger (median age, 64.5 vs. 70 years, adjusted odds ratio [OR] per age 0.975, 95% confidence interval [CI] 0.955-0.995, P = 0.016) and had higher positive surgical margin rates (31.2% vs. 18.4%, adjusted OR 2.376, 95% CI 1.188-4.754, P = 0.014) than those with SCC. However, according to the weighted model, the survival outcomes were comparable (hazard ratio for progression-free survival, 1.088, 95% CI 0.740-1.601, P = 0.667 and hazard ratio for overall survival, 1.008, 95% CI 0.646-1.573, P = 0.973). Similar associations were observed when the cohort was stratified by age (≤70 or >70 years), stage (I-II or III-IV), and surgical margin (negative or positive) (all, P > 0.05). CONCLUSION: Vulvar adenocarcinoma is characterized by a younger age at diagnosis and higher positive surgical margin rates than SCC, but the survival outcomes are comparable.

A survey of the reactivity of in vitro diagnostic bilirubin reagents developed in Japan using artificially prepared bilirubin materials: A comparison of synthetic delta, unconjugated, and taurine-conjugated bilirubin.

BACKGROUND: In vitro diagnostic bilirubin reagents based on oxidation with bilirubin oxidase or vanadic acid for total and direct-reacting bilirubin are widely used in Japan; however, their reactivity to unconjugated and conjugated bilirubin and delta bilirubin has not been completely disclosed by manufacturers. We used artificially prepared bilirubin materials to investigate the reactivity with four in vitro diagnostic bilirubin reagents. METHODS: Porcine unconjugated bilirubin solution, chemically synthesized ditaurobilirubin solution, and chemically synthesized delta bilirubin solution were used as surrogates of naturally occurring unconjugated bilirubin, conjugated bilirubin, and delta bilirubin, respectively. The total bilirubin and direct-reacting bilirubin concentrations were measured by three bilirubin oxidase methods and one vanadic acid method, and the observed concentrations were compared with those obtained by the diazo-based reference measurement procedure. RESULTS: The unconjugated bilirubin and delta bilirubin concentrations were similar when any of the four in vitro diagnostic bilirubin reagents were used during total bilirubin measurement. This was consistent with reference measurement procedure and exhibited a converged inter-method variation. Compared with reference measurement procedure, significantly low ditaurobilirubin concentrations were observed by the in vitro diagnostic bilirubin reagents despite the converged inter-method variation. In delta bilirubin measurement, some reagents reacted doubtfully with unconjugated bilirubin, while showed lower ditaurobilirubin concentrations than its corresponding total bilirubin concentration. Reactivity with delta bilirubin was different for each method including reference measurement procedure. Some reagents were developed to react less with delta bilirubin and others to strongly react with delta bilirubin. CONCLUSIONS: We revealed the reactivity of IVD-TB and IVD-DB reagents to artificially prepared bilirubin materials, and their consistency with reference measurement procedure. The delta bilirubin data results vary depending on the reagents used.

Robot-assisted laparoscopic hysterectomy for endometrial cancer in a patient with Herlyn-Werner-Wunderlich syndrome.

Herlyn-Werner-Wunderlich syndrome, a rare Mullerian duct anomaly, includes a triad of uterine didelphys, obstructed haemivagina and ipsilateral renal agenesis. A 58-year-old woman with Herlyn-Werner-Wunderlich syndrome, reported of recurrent genital bleeding for 9 years, was finally diagnosed with endometrial cancer. She had a history of vaginal septum resection and nephrectomy of atrophic right kidney. MRI demonstrated uterine didelphys, a tumour filling the left uterus and a cyst on the right lateral side of the uterus. Robot-assisted hysterectomy, including bilateral salpingo-oophorectomy and pelvic lymphadenectomy, was performed. As the cyst communicated with the right cervix, but not with the urinary tract, a Gartner duct cyst was diagnosed. Uncertain diagnosis and delay of treatment in endometrial cancer may occur in patients with Herlyn-Werner-Wunderlich syndrome. We should preoperatively fully evaluate the anatomy of the uterus and surrounding tissues and plan surgical procedures, especially in patients with urogenital malformations.

[A case of autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy].

A 46-year-old man developed acute meningo-encephalitis with confusion, headache, fever, intractable hiccups, dysuria, myoclonus/tremor, and ataxia. Analysis of cerebrospinal fluid (CSF) showed elevated levels of cell counts and protein. Brain MRI demonstrated multiple linear increased FLAIR signals in bilateral basal ganglia and corona radiata. Repeated MRI showed T2 hyperintensity areas in the lower brainstem, sparing the area postrema. Immunotherapy with intravenous high-dose steroid and subsequent oral steroid was successful, and the symptoms improved completely. Later MRI study showed a striking resolution. Glial fibrillary acidic protein (GFAP) α antibody was positive in the CSF, while anti-aquaporin-4 antibody, anti-myelin oligodendrocyte glycoprotein antibody, and N-methyl-D-aspartate receptor antibody were all negative. There were no relapses at final follow-up of 6 months after onset. Autoimmune GFAP astrocytopathy is not an uncommon immune-mediated inflammatory disorder in the central nervous system.

Management of pulmonary contusions during the COVID-19 pandemic.

BACKGROUND: Coronavirus disease (COVID-19) is an emerging infectious disease with human-to-human transmission. Early identification of patients with COVID-19 is important in preventing its spread. CASE PRESENTATION: A 36-year-old man with a fever for 3 days fell from the 5th floor and was transported to our emergency department. Pan-scan computed tomography (CT) revealed multiple ground-glass opacities just below the pleura, pelvic fractures, thoracic vertebral fracture (Th11), and right femoral fracture. COVID-19 was ruled out based on negative real-time reverse transcription-polymerase chain reaction results on days 2 and 3, and a reduction in the multiple ground-glass opacities on CT carried out on day 5. Until the suspicion of COVID-19 was cleared, strict and standardized processing procedures were implemented in the same way as for a patient with COVID-19. CONCLUSIONS: It is very difficult to rapidly differentiate between pulmonary contusions and COVID-19, as these conditions have many similarities on CT.

Extremely Acute-Onset Cerebral Fat Embolism.

Cerebral fat embolism (CFE) causes the neurological involvement observed in fat embolism syndrome, which is a post-traumatic complication seen mostly after long bone fractures and usually presents 24-72 h after the injury. An early 80s female who sustained an isolated traumatic fracture of the left distal femur without dislocation was alert on admission but fell into a coma 55 min after the injury. Brain computed tomography showed no abnormalities. Brain magnetic resonance imaging was performed approximately 5 h after the accident, and diffusion-weighted images revealed hyperintense, dot-like lesions disseminated in a "starfield" pattern in the brain. The patient was diagnosed with CFE and admitted to the intensive care unit. The day after the injury, the patient developed petechiae on the palpebral conjunctiva and was still comatose 4 months after the trauma. The current patient developing CFE in less than 1 h after a traumatic injury illustrates that CFE should be considered in patients with sudden deterioration of consciousness within 1 h after long bone fractures.
