Adenosine phosphate-based detection of worker exposure to contaminated water during bathroom cleaning.

Background: Workers who clean bathrooms at medical facilities may be regularly exposed to contaminated water harboring pathogenic microbes and should wear personal protective equipment (PPE) to prevent such exposure at medical facilities, which has not been quantitatively assessed. This study quantified the exposure risk from contaminated water when cleaning restrooms at medical facilities and clarified the importance of wearing PPE.

Methods: Existing urinals, toilets, and handwashing sinks (16 each) in a hospital environment were coated with a simulated contaminant containing adenosine phosphate and cleaned with a brush or sponge by workers in PPE.

A novel case of concurrent occurrence of demyelinating-polyneuropathy-causing PMP22 duplication and SOX10 gene mutation producing severe hypertrophic neuropathy.

Background: Hereditary motor and sensory neuropathy, also referred to as Charcot-Marie-Tooth disease (CMT), is most often caused by a duplication of the peripheral myelin protein 22 (PMP22) gene. This duplication causes CMT type 1A (CMT1A). CMT1A rarely occurs in combination with other hereditary neuromuscular disorders.

Two cases of calcineurin inhibitor-associated reversible posterior leukoencephalopathy syndrome in renal transplant recipients.

Reversible posterior leukoencephalopathy syndrome (RPLS) is one of the important side effects of calcineurin inhibitors (CNIs). Magnetic resonance imaging (MRI) of the brain is useful for the diagnosis of RPLS, showing the edema primarily in the cortex and subcortical white matter of the posterior brain regions. Interruption of CNIs is essential for the treatment of patients with RPLS.

Clinical application of (11)C-methionine positron emission tomography for evaluation of pancreatic function.

Introduction: In recent years, it has become increasingly necessary to evaluate pancreatic function after pancreatectomy, but few precise methods are available.

Aims: To evaluate different surgical techniques for pancreatectomy in terms of the preservation of pancreatic function by (11)C-methionine positron emission tomography (PET), which determines amino acid metabolism in the pancreas.

Methodology: The study included 33 pancreatectomy cases: 5 of distal pancreatectomy, 5 of pancreaticoduodenectomy, 10 of pylorus-preserving pancreaticoduodenectomy, 7 of duodenum-preserving pancreatic head resection, and 6 of inferior pancreatic head resection.

Preduodenal portal vein in the adult.

Preduodenal portal vein (PDPV) is a rare developmental anomaly. We recently encountered this anomaly in a 73-year-old woman who had gastric cancer and colonic cancer with liver metastasis. The PDPV was diagnosed preoperatively by computed tomography and angiography.
