Care at critical care medical centers is associated with improved outcomes in patients with accidental hypothermia: a historical cohort study from the J-Point registry.

Aim: The recommendation that patients with accidental hypothermia should be transported to specialized centers that can provide extracorporeal life support has not been validated, and the efficacy remains unclear.

Methods: This was a multicenter retrospective cohort study of patients with a body temperature of ≤35°C presenting at the emergency department of 12 hospitals in Japan between April 2011 and March 2016. We divided the patients into two groups based on the point of care delivery: critical care medical center (CCMC) or non-CCMC.

Impact of Routine Infant BCG Vaccination on COVID-19.

Objectives: In Japan, the first case of coronavirus disease 2019 (COVID-19) was diagnosed on January 15, 2020 and subsequent infections rapidly increased. The Bacillus Calmette-Guérin (BCG) vaccination program is the principal element of tuberculosis control in Japan. We investigated the impact of routine infant BCG vaccination on prevention of local COVID-19 spread.

Two susceptible HLA-DRB1 alleles for multiple sclerosis differentially regulate anti-JC virus antibody serostatus along with fingolimod.

Background: Progressive multifocal leukoencephalopathy (PML) caused by JC virus (JCV) is a rare but serious complication of some disease-modifying drugs used to treat multiple sclerosis (MS). Japanese MS patients treated with fingolimod were reported to be 10 times more likely to develop PML than equivalent patients in other countries. The strongest susceptibility human leukocyte antigen (HLA) class II alleles for MS are distinct between races (DRB1*15:01 for Caucasians and DRB1*04:05 and DRB1*15:01 for Japanese); therefore, we investigated whether HLA class II alleles modulate anti-JCV antibody serostatus in Japanese MS patients with and without fingolimod.

Lumbar vertebral osteomyelitis and psoas abscess caused by Actinomyces israelii after an operation under general anesthesia in a patient with end-stage renal disease: a case report.

Background: Actinomycosis is a chronic, slowly progressive infection caused by the Actinomyces species. Lumbar vertebral involvement of Actinomyces israelii is extremely rare; this is the first case report of lumbar vertebral osteomyelitis and psoas abscess caused by Actinomyces israelii after an operation under general anesthesia.

Case Presentation: A 66-year-old Japanese man with end-stage renal disease was admitted to our hospital for an operation for cervical canal stenosis.

Impact of rewarming rate on the mortality of patients with accidental hypothermia: analysis of data from the J-Point registry.

Background: Accidental hypothermia (AH) is defined as an involuntary decrease in core body temperature to < 35 °C. The management of AH has been progressing over the last few decades, and numerous techniques for rewarming have been validated. However, little is known about the association between rewarming rate (RR) and mortality in patients with AH.

Prognostic ability of the sequential organ failure assessment score in accidental hypothermia: a multi-institutional retrospective cohort study.

Background: Severe accidental hypothermia (AH) is life threatening. Thus, prognostic prediction in AH is essential to rapidly initiate intensive care. Several studies on prognostic factors for AH are known, but none have been established.

Indoor Versus Outdoor Occurrence in Mortality of Accidental Hypothermia in Japan: The J-Point Registry.

The impact of the location where accidental hypothermia (AH) occurs has not been fully investigated thus far. This was a multicenter retrospective study of patients with a body temperature ≤35°C obtained at the emergency department of 12 hospitals in Japan between April 2011 and March 2016. We divided the patients into two groups according to the location where AH occurred (indoor group versus outdoor group).

Correction to: The development and validation of a "5A" severity scale for predicting in-hospital mortality after accidental hypothermia from J-point registry data.

The development and validation of a "5A" severity scale for predicting in-hospital mortality after accidental hypothermia from J-point registry data.

Background: Accidental hypothermia is a serious condition that requires immediate and accurate assessment to determine severity and treatment. Currently, accidental hypothermia is evaluated using the Swiss grading system which uses core body temperature and clinical findings; however, research has shown that core body temperature is not associated with in-hospital mortality in urban settings. Therefore, we developed and validated a severity scale for predicting in-hospital mortality among urban Japanese patients with accidental hypothermia.

Atraumatic splenic rupture in a peritoneal dialysis patient.

Splenic hemorrhage is a potentially life-threatening complication usually occurring after blunt trauma to the abdomen. Atraumatic splenic rupture (ASR) is an uncommon condition, and mostly results from pathology affecting the spleen, such as tumor infiltration or infection. Here, we report a case of atraumatic rupture of a normal spleen in a patient undergoing peritoneal dialysis, and review similar cases in the literature.

Characteristics and outcomes of accidental hypothermia in Japan: the J-Point registry.

Background: Accidental hypothermia (AH) has higher incidence and mortality in geriatric populations. Japan has a rapidly ageing population, and little is known about the epidemiology of hypothermia in this country.

Methods: We created an AH registry based on retrospective review of patients visiting the ED of 12 institutions with temperature ≤35°C between April 2011 and March 2016.

Long-term neurological and neuropsychological complications of sulfur mustard and Lewisite mixture poisoning in Chinese victims exposed to chemical warfare agents abandoned at the end of WWII.

In August 2003, 44 victims were poisoned by chemical warfare agents (CWAs) leaked from five drums that were excavated at a construction site in Qiqihar, Northeast China. The drums were abandoned by the former Japanese imperial army during World War II and contained a mixture of Sulfur mustard (SM) and Lewisite. We carried out a total of six regular check-ups between 2006 and 2014, and from 2008 we added neurological evaluations including neuropsychological test and autonomic nervous function test in parallel with medical follow-up as much as was possible.

[Dimethyl Fumarate in Multiple Sclerosis].

At the end of 2016, dimethyl fumarate (DMF) was approved as the sixth disease-modifying drug for multiple sclerosis by the Pharmaceuticals and Medical Devices Agency of Japan. Two randomized, placebo-controlled, phase III studies (DEFINE and CONFIRM) showed beneficial effects in patients in Western countries, with relapsing-remitting multiple sclerosis (RRMS). Some of the benefits included a decreased annual relapse rate, inhibition of disease activity (shown using brain magnetic resonance imaging), and a decreased proportion of patients with confirmed disease progression.

Development and validation of a set of six adaptable prognosis prediction (SAP) models based on time-series real-world big data analysis for patients with cancer receiving chemotherapy: A multicenter case crossover study.

Background: We aimed to develop an adaptable prognosis prediction model that could be applied at any time point during the treatment course for patients with cancer receiving chemotherapy, by applying time-series real-world big data.

Methods: Between April 2004 and September 2014, 4,997 patients with cancer who had received systemic chemotherapy were registered in a prospective cohort database at the Kyoto University Hospital. Of these, 2,693 patients with a death record were eligible for inclusion and divided into training (n = 1,341) and test (n = 1,352) cohorts.

Once-daily glatiramer acetate decreases magnetic resonance imaging disease activity in Japanese patients with relapsing-remitting multiple sclerosis.

Objective: Multiple sclerosis (MS) prevalence, clinical patterns, and treatment responses vary between races and geographical latitudes. Glatiramer acetate (GA; Copaxone) has provided a safe, effective treatment option for relapsing-remitting MS patients in the USA, European nations, and other countries for decades. The objective of the present study was to assess the safety and efficacy of GA in reducing magnetic resonance imaging disease activity in Japanese patients with active relapsing-remitting MS.

Prognostic value of oligoclonal IgG bands in Japanese clinically isolated syndrome converting to clinically definite multiple sclerosis.

We evaluated the impact of brain MRI findings and oligoclonal IgG bands (OCBs) on conversion to clinically definite multiple sclerosis (CDMS) in 26 Japanese patients with clinically isolated syndrome (CIS). 19.2% had OCBs positivity and 3.

Steroid-resistant nephrotic syndrome as the initial presentation of nail-patella syndrome: a case of a de novo LMX1B mutation.

Background: Nail-patella syndrome (NPS) is an autosomal dominant disorder caused by mutations in the LMX1B gene and is characterized by nail dysplasia, skeletal abnormalities, and nephropathy. We herein report a case of steroid-resistant nephrotic syndrome (SRNS) prior to overt orthopedic symptoms in a patient with NPS.

Case Presentation: A 24-year-old woman presented to our hospital with knee pain.

Eye-Mouth Associated Movement in the Human Newborn and Very Young Infant.

Background: The aim of this study is to demonstrate that goal-directed eye-mouth associated movement exists in the newborn and very young infant.

Methods: The participants were 17 healthy term newborns or very young infants whose ages at the time of the first examination ranged from 1 to 24 days. The examiner held the tip of an index finger 20 to 30 cm in front of a participant's mouth, then suddenly moved it directly toward the mouth.

Two cases of delayed cardiac tamponade due to pericarditis after pulmonary vein (PV) isolation for atrial fibrillation.

Catheter ablation is an established treatment for atrial fibrillation (AF). The incidence of major complications related to the procedure is reported to be 4.5%, and delayed cardiac tamponade (DCT) is a rare, although recently recognized, complication.

Recurrent diarrhea as a manifestation of temporal lobe epilepsy.

A woman with temporal lobe epilepsy manifesting with repeated episodes of sudden diarrhea and loss of consciousness is reported. A 63-year-old, right-handed female presented with chief complaints of sudden diarrhea and loss of consciousness for almost three decades. The first attack occurred in her 30s, and similar attacks repeated several times in a year.

[Computed tomography (CT) assessment of the postoperative change of pericardial fat pad used in pulmonary surgery].

The purpose of this study is to clarify the postoperative change of pericardial fat pad used in pulmonary resection to reinforce bronchial suture or bronchial stump. 5 cases who received chest computed tomography (CT) examination 2 times or more after the operation (once within one week after the operation) were enrolled. For evaluation, scoring system from 1 to 4 according to the percentage of remaining pericardial fat pad was applied(1 point: 0∼19%, 2 point: 20∼49%, 3 point: 50∼79%, 4 point: 80∼100%).
