Effect of studying abroad on catch-up vaccination in young adults: A study using the Japan Pretravel Consultation Registry.

Purpose: To investigate the effect of studying abroad on catch-up vaccination coverage for measles, rubella, mumps, varicella, and tetanus during the pretravel consultation among young adult travelers.

Methods: This retrospective cohort study analyzed data from the Japan Pretravel Consultation Registry (J-PRECOR) on individuals aged 18-21 years with childhood vaccination records. Propensity score weighting was used to estimate the average treatment effect on the proportion of participants receiving catch-up vaccination.

Ambulance Traffic Crashes in Japan: Characteristics of Casualties and Efforts to Improve Ambulance Safety.

Background: An ambulance traffic crash not only leads to injuries among emergency medical service (EMS) professionals but also injures patients or their companions during transportation. We aimed to describe the incidence of ambulance crashes, seating location, seatbelt use for casualties (ie, both fatal and nonfatal injuries), ambulance safety efforts, and to identify factors affecting the number of ambulance crashes in Japan.

Methods: We conducted a nationwide survey of all fire departments in Japan.

Optimal tentative abdominal closure for open abdomen: a multicenter retrospective observational study (OPTITAC study).

Background: Primary fascia closure is often difficult following an open abdomen (OA). While negative-pressure wound therapy (NPWT) is recommended to enhance successful primary fascia closure, the optimal methods and degree of negative pressure remain unclear. This study aimed to elucidate optimal methods of NPWT as a tentative abdominal closure for OA to achieve primary abdominal fascia closure.

Characteristics and potential quality indicators for evaluating pre-travel consultations in Japan hospitals: the Japan Pretravel consultation registry (J-PRECOR).

Background: Awareness of pre-travel consultations (PTCs) and prevention methods for overseas travel-related diseases, and the understanding of PTCs among Japanese travelers and medical professionals remains low in Japan. A multicenter registry was established to examine PTCs in Japan. This study assessed the PTC implementation rate and examined the indicators of PTCs that can be used as criteria for evaluating quality.

A 66-year old man presented to our hospital due to gait disturbance. He was unable to stand or walk without assistance. Laboratory tests revealed macrocytic anemia and an extremely low serum vitamin B level.

Fatal hemoperitoneum due to rupture of mesenteric artery in remission state of microscopic polyangiitis, concomitant with severe hypertension and posterior reversible encephalopathy syndrome: an autopsy case report.

Microscopic polyangiitis (MPA) is a type of necrotizing vasculitis associated with high levels of myeloperoxidase-specific antineutrophil cytoplasmic antibody (MPO-ANCA). While generally associated with renal dysfunction, MPA can also cause intraabdominal hemorrhage in rare cases. A 66-year-old man was admitted to our hospital for renal dysfunction, numbness, and weight loss for 3 months.

Wireless Light-emitting Marker Using Magnetic Field Resonance for Laparoscopic Gastrointestinal Surgery.

Background: In laparoscopic gastrointestinal surgery, the location of the tumor is identified mainly with marking methods, such as ink tattooing and intraoperative gastrointestinal endoscopy and marking with a metal clip followed by confirmation with intraoperative x-ray fluoroscopy. Each method has disadvantages, such as complexity, instability of ink sticks, and radiation exposure. Thus, a simple and less-invasive marking method is needed.

Combined Strategy of Burr Hole Surgery and Elective Craniotomy under Intracranial Pressure Monitoring for Severe Acute Subdural Hematoma.

Burr hole surgery in the emergency room can be lifesaving for patients with acute subdural hematoma (ASDH). In the first part of this study, a strategy of combined burr hole surgery, a period of intracranial pressure (ICP) monitoring, and then craniotomy was examined for safe and effective treatment of ASDH. Since 2012, 16 patients with severe ASDH with indications for burr hole surgery were admitted to Kenwakai Otemachi Hospital.

An elderly-onset neuroblastoma concomitant with minimal change nephrotic syndrome: the first autopsy case report.

Background: Neuroblastoma is a well-known embryonal cancer; however, adult-onset neuroblastomas are rare. The systemic symptoms are related to catecholamine excretion or intraabdominal mass effects. Only two cases of neuroblastoma with nephrotic syndrome have previously been reported.

Three-day antibiotic treatment for acute cholangitis due to choledocholithiasis with successful biliary duct drainage: A single-center retrospective cohort study.

Objectives: Given that the optimal antibiotic treatment duration for acute cholangitis with successful biliary drainage remains unknown, this study aimed to validate whether antibiotic treatment duration could be reduced to ≤3 days among patients presenting the same.

Methods: This retrospective study included patients who presented with mild to moderate acute cholangitis due to choledocholithiasis who had undergone successful biliary drainage through endoscopic retrograde cholangiopancreatography (ERCP). After that, 30-day mortality rates and 3-month recurrence rates following short-course antibiotic treatment (SCT, ≤3 days) and long-course antibiotic treatment (LCT, ≥4 days) were compared.

[A case of post-cardiac arrest syndrome presenting with lateralized periodic discharges evolving to a cyclic seizure pattern on electroencephalogram].

A 53-year-old man with hypertension experienced sudden cardiopulmonary arrest. Ambulance crews detected ventricular fibrillation that responded to defibrillation. Cardiopulmonary resuscitation resulted in return of spontaneous circulation (ROSC) after 30 minutes.

Procedural sedation and analgesia in the emergency department in Japan: interim analysis of multicenter prospective observational study.

Purpose: Procedural sedation and analgesia (PSA) is widely performed outside of the operating theater, often in emergency departments (EDs). The practice and safety of PSA in the ED in an aging society such as in Japan have not been well described. We aimed to characterize the practice pattern of PSA including indications, pharmacology and incidence of adverse events (AEs) in Japan.

Suture-induced arthritis as a clinical mimicker of septic arthritis.

Foreign body-induced arthritis is a rare etiology of mono-arthritis. It should be suspected in the case of postoperative arthritis, even if some decades have passed since surgery. Histopathology of the tissues is required for a definitive diagnosis, and debridement is essential for complete recovery.

[An adult case of group A streptococcus meningitis associated with steroid-responsive meningoencephalitis].

A previously healthy 80-year-old woman presented to our service in a comatose state. On examination the patient had fever and neck stiffness. Laboratory investigation showed polymorphonuclear pleocytosis in cerebro-spinal fluid (CSF).

The first case report of emphysematous pyelonephritis and bacteremia due to Oligella urethralis.

Oligella urethralis (O. urethralis) is an organism that rarely causes infections in humans. We report the case of a 90-year-old bedridden woman with progressive dementia who was placed in a long-term-care facility.

Resuscitative endovascular balloon occlusion of the aorta in trauma patients in youth.

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has received increasing attention for critically uncontrolled hemorrhagic shock. However, the efficacy of REBOA in patients in youth is unknown.

Objectives: The aim of this study was to evaluate the mortality and characteristics of patients of age ≤18 years with severe traumatic injury who received REBOA.

[A case of Staphylococcus aureus meningitis associated with cryoglobulin-related renal failure and clinically mild encephalitis/encephalopathy with a reversible splenial lesion].

A 59-years old man, having untreated hypertension and diabetes, was admitted to our hospital because of lumbago and fever. A T2-weighted image of spine showed increased signal intensity of vertebra at L3 and L4. Methicillin-susceptible staphylococcus aureus (MSSA) infection was confirmed by blood culturing.

Survival of severe blunt trauma patients treated with resuscitative endovascular balloon occlusion of the aorta compared with propensity score-adjusted untreated patients.

Background: Despite a growing call for use of resuscitative endovascular balloon occlusion of the aorta (REBOA) for critically uncontrolled hemorrhagic shock, there is limited evidence of treatment efficacy. We compared the mortality between patients who received a REBOA with those who did not, adjusting for the likelihood of treatment and injury severity, to measure efficacy.

Methods: We analyzed observational prospective data from the Japan Trauma Data Bank (2004-2011) to compare the mortality between adult patients who received a REBOA with those who did not.

Detailed clinicopathological characteristics and possible lymphomagenesis of type II intestinal enteropathy-associated T-cell lymphoma in Japan.

Twenty-six Japanese cases of type II enteropathy-associated T-cell lymphoma (EATL) were examined. Multiple tumors throughout the small intestine were found in 15 patients (58%) and duodenal and colonic mucosal lesions in 8 and 6 cases, respectively. Histologically, intramucosal tumor spread and a zone of neoplastic intraepithelial lymphocytes (IELs) neighboring the main transmural tumors were detected in 20 (91%) and 17 (77%) of the 22 cases examined, respectively.
