A 60-year-old Japanese woman was hospitalized for cardiogenic shock 24 days after receiving the second dose of the COVID-19 BNT162b2 vaccine. Impella-CP left ventricular assist device implantation and venoarterial peripheral extracorporeal membranous oxygenation were immediately initiated along with inotropic support and steroid pulse therapy, as an endomyocardial biopsy specimen showed myocarditis. Three weeks later, her cardiac function had recovered, and she was discharged. An immune response associated with the presence of spike protein in cardiac myocytes may be related to myocarditis in the present case because of positive immunostaining for severe acute respiratory syndrome coronavirus 2 spike protein and C4d in the myocardium.

A 36-year-old man was admitted to our hospital because of urinary retention and muscle weakness affecting all 4 limbs after receiving a H1N1 09 influenza vaccination. Magnetic resonance imaging demonstrated multiple lesions in his brain and spinal cord. Furthermore, nerve conduction study showed acute sensorimotor neuropathy, and anti-GM2 antibodies were detected in his serum. Based on the temporal association and exclusion of alternative etiologies, we made a diagnosis of acute disseminated encephalomyelitis (ADEM) and Guillain-Barré syndrome (GBS). To our knowledge, this is the first case of co-morbid ADEM and GBS after influenza vaccination with positive anti-ganglioside antibodies.

COVID-19 vaccine-related myocarditis has been reported worldwide. We herein report two Japanese cases with suspected vaccine-related myocarditis. A 27-year-old man was admitted with chest pain 4 days after the second vaccination. An electrocardiogram (ECG) did not reveal any significant abnormalities. The second patient, a 37-year-old man, was admitted with chest pain 9 days after the first vaccination. His ECG exhibited ST-elevation in multiple leads. In both cases, cardiac magnetic resonance imaging findings were consistent with myocarditis. They recovered with symptomatic relief within a few days. These cases suggest that the benefit of COVID-19 vaccination exceeds the risk of vaccine-related myocarditis.

Objective To investigate the causes of neurological manifestations in girls immunized with the human papillomavirus (HPV) vaccine. Methods During the past nine months, 44 girls visited us complaining of several symptoms after HPV vaccination. Four patients with other proven disorders were excluded, and the remaining forty subjects were enrolled in this study. Results The age at initial vaccination ranged from 11 to 17 years, and the average incubation period after the first dose of the vaccine was 5.47±5.00 months. Frequent manifestations included headaches, general fatigue, coldness of the legs, limb pain and weakness. The skin temperature examined in 28 girls with limb symptoms exhibited a slight decrease in the fingers (30.4±2.6°C) and a moderate decrease in the toes (27.1±3.7°C). Digital plethysmograms revealed a reduced height of the waves, especially in the toes. The limb symptoms of four girls were compatible with the Japanese clinical diagnostic criteria for complex regional pain syndrome (CRPS), while those in the other 14 girls were consistent with foreign diagnostic criteria for CRPS. The Schellong test identified eight patients with orthostatic hypotension and four patients with postural orthostatic tachycardia syndrome. The girls with orthostatic intolerance and CRPS commonly experienced transient violent tremors and persistent asthenia. Electron-microscopic examinations of the intradermal nerves showed an abnormal pathology in the unmyelinated fibers in two of the three girls examined. Conclusion The symptoms observed in this study can be explained by abnormal peripheral sympathetic responses. The most common previous diagnosis in the studied girls was psychosomatic disease. The social problems of the study participants remained unresolved in that the severely disabled girls stopped going to school.

Vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been developed and administered worldwide. There have been reports of neurological adverse events following immunization (AEFIs). We herein report a case of refractory longitudinally extensive transverse myelitis in a 75-year-old Japanese man following the first dose of the BNT162b2 vaccine. The patient developed total sensory loss below the umbilicus and complete paralysis in both legs. Although he was treated with steroid therapy and plasma exchange, his recovery was limited, and severe sequelae remained. Further studies, including large epidemiological studies, are required to understand the association between SARS-CoV-2 vaccines and neurological AEFI.

We herein report a 71-year-old woman presented with a fever, arthralgia, general malaise and leg muscle stiffness following administration of the COVID-19 mRNA vaccine (Comirnaty, Pfizer-BioNTech). Laboratory findings showed an elevated C-reactive protein level and erythrocyte sedimentation rate. In addition, Gallium-67 scintigraphy demonstrated an increased uptake in multiple joints. Typing of HLA revealed the presence of the DRB1*0404/*0803 allele. These findings met the diagnostic criteria for polymyalgia rheumatica (PMR), and when we started steroid treatment, her symptoms improved rapidly. This patient developed PMR after receiving a COVID-19 mRNA vaccine (Comirnaty, Pfizer-BioNTech). This case is considered to be valuable, as the HLA-DRB1 allele was also confirmed.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease recently discovered in northeastern and central China that is caused by a novel bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). Humans are primarily infected through tick bites. Four previous reports have discussed SFTS infection from person to person, all cases of which were symptomatic. In this report, we analysed the epidemiological and clinical data for a cluster of cases, including one case of secondary-asymptomatic infection, and review the literature regarding SFTSV transmission from person to person. We conclude that SFTSV caused the asymptomatic infections via person-to-person contact with infected blood.

We herein report a 15-year-old girl who developed rapid progressive muscle weakness soon after the third injection of a bivalent human papilloma virus (HPV) vaccine. Although immunotherapies were performed for possible vaccine-related disorders, she died of respiratory failure 14 months after the onset of the disease. A genetic analysis identified a heterozygous p.P525L mutation of the fused in sarcoma (FUS) gene, and a histopathological analysis was also consistent with FUS-associated amyotrophic lateral sclerosis (ALS) without any evidence of neuroinflammation. We concluded the diagnosis to be FUS-ALS, although we cannot completely rule out the possibility that the vaccination worked as a trigger.

Objective Considering the possibility that eosinophilic inflammation is involved in the pathogenesis of chronic epipharyngitis, this study determined whether or not the exhaled nitric oxide level of patients changed after epipharyngeal abrasive therapy (EAT). The diagnosis and follow-up of patients with chronic epipharyngitis were based on the endoscopic findings. If the exhaled nitric oxide level reflects the pathology of a patient with chronic epipharyngitis, the exhaled nitric oxide test can be performed for a follow-up examination as an objective test for chronic epipharyngitis. Methods The study period was 12 months, starting from February 2020. The age distribution and patients' median age and gender were retrospectively reviewed using medical records. Exhaled nitric oxide levels were measured before and after endoscopic EAT at the initial examination and before and after blind EAT at the follow-up examination. Patients or Materials Ninety-six new patients were included in this study. Results The study included 27 men and 69 women (median age [range], 45 [17-82] years old). When patients with chronic epipharyngitis were treated using EAT, exhaled nitric oxide levels were significantly lower after EAT than before EAT at the initial visit. Six months after EAT, the exhaled nitric oxide level was significantly lower than that at the initial visit. Conclusion During the follow-up examination of patients with chronic epipharyngitis, the exhaled nitric oxide test may be an effective objective test, along with changes in endoscopic findings.

We herein present two cases of acute disseminated encephalomyelitis (ADEM) following vaccination against human papilloma virus (HPV). Case 1 experienced diplopia and developed an unstable gait 14 days after a second vaccination of Cervarix. Brain magnetic resonance imaging (MRI) showed an isolated small, demyelinating lesion in the pontine tegmentum. Case 2 experienced a fever and limb dysesthesia 16 days after a second vaccination of Gardasil. Brain MRI revealed hyperintense lesion in the pons with slight edema on a T2-weighted image. Both cases resolved completely. It is important to accumulate further data on confirmed cases of ADEM temporally associated with HPV vaccination.

Objectives The influential factors for anti-severe acute respiratory syndrome coronavirus 2 spike protein antibody (S-ab) levels were assessed after the administration of BNT162b2 mRNA coronavirus disease-2019 (COVID-19) vaccine at short and medium terms. Methods A total of 470 healthcare workers (118 males, mean age 41.0±11.9 years) underwent serum S-ab level measurement at 3 and 8 months after two inoculations of BNT162b2 vaccine given 3 weeks apart, who had no history of COVID-19 were enrolled in this study. The changes and differences after vaccination due to gender and adverse reactions of S-ab were analyzed. Results Systemic adverse reactions incidence (48%) was significantly higher after the second dose than after the first dose (8%). S-ab levels decreased as the age increased (from the 20s to 60s) in both measurements. S-ab level 8 months after the second inoculation (median 476.3 [interquartile range {IQR} 322.4-750.6] U/mL) was significantly lower than that after 3 months (977.5 [637.2-1409.0] U/mL; P <0.001). The median decrease rate of S-ab levels in 5 months was 50.3 (IQR 40.3-62.6) % and those differences were not observed among all generations. Gender-associated differences in S-ab levels were not observed; however, a significant relationship between higher S-ab levels and the systemic adverse reactions was observed at both measurements. Conclusions The systemic adverse reaction is an independent factor for higher S-ab levels at short and medium terms after BNT162b2 vaccination as demonstrated in our data.

Objective Kakkonto, a Japanese herbal medicine, is frequently used to treat the common cold not only with a physician's prescription, but also in self-medication situations. This study aimed to examine whether Kakkonto prevents the aggravation of cold symptoms if taken at an early stage of illness compared with a well-selected Western-style multiple cold medicine. Methods This study was a multicenter, active drug-controlled, randomized trial. Adults 18 to 65 years of age who felt a touch of cold symptoms and visited 15 outpatient healthcare facilities within 48 hours of symptoms onset were enrolled. The participants were randomly assigned to two groups: one treated with Kakkonto (Kakkonto Extract-A, 6 g/day) (n=209) and one treated with a Western-style multiple cold medicine (Pabron Gold-A, 3.6 g/day) (n=198) for at most four days. The primary outcome of this study was the aggravation of cold, nasal, throat or bronchial symptoms, scored as moderate or severe and lasting for at least two days within five days after entry into the study. Results Among the 410 enrollees, 340 (168 in the Kakkonto group and 172 in the Pabron group) were included in the analyses. The proportion of participants whose colds were aggravated was 22.6% in the Kakkonto group and 25.0% in the Pabron group (p=0.66). The overall severity of the cold symptoms was not significantly different between the groups. No harmful adverse events occurred in either group. Conclusion Kakkonto did not significantly prevent the progression of cold symptoms, even when prescribed at an early stage of the disease.

Pivoxil-containing cephalosporins can result in symptomatic hypocarnitinemia in children. We herein report a case of an 85-year-old man at risk of carnitine deficiency who developed relapsing symptomatic hypoglycemia after treatment with cefcapene pivoxil for urinary tract infection. On admission, laboratory tests showed low blood carnitine concentrations with low normal blood ketone levels. The patient was successfully treated by the oral administration of levocarnitine and dietary modification, including aggressive consumption of meat and dairy products, and remained symptom-free for nine months after the correction of carnitine concentrations. Healthcare providers should be cautious when prescribing pivoxil-containing antimicrobials to patients at high risk of hypocarnitinemia.

Objective Although caloric restriction is a widely used intervention to reduce body weight and insulin resistance, many patients are unable to comply with such dietary therapy for long periods. The clinical effectiveness of low-carbohydrate diets was recently described in a position statement of Diabetes UK and a scientific review conducted by the American Diabetes Association. However, randomised trials of dietary interventions in Japanese patients with type 2 diabetes are scarce. Therefore, the aim of this study was to examine the effects of a non-calorie-restricted, low-carbohydrate diet in Japanese patients unable to adhere to a calorie-restricted diet. Methods The enrolled patients were randomly allocated to receive a conventional calorie-restricted diet or low-carbohydrate diet. The patients received consultations every two months from a registered dietician for six months. We compared the effects of the two dietary interventions on glycaemic control and metabolic profiles. Results The HbA1c levels decreased significantly from baseline to six months in the low-carbohydrate diet group (baseline 7.6±0.4%, six months 7.0±0.7%, p=0.03) but not in the calorie-restricted group (baseline 7.7±0.6%, six months 7.5±1.0%, n.s.), (between-group comparison, p=0.03). The patients in the former group also experienced improvements in their triglyceride levels, without experiencing any major adverse effects or a decline in the quality of life. Conclusion Our findings suggest that a low-carbohydrate diet is effective in lowering the HbA1c and triglyceride levels in patients with type 2 diabetes who are unable to adhere to a calorie-restricted diet.
