Screening for musculoskeletal problems in children using a questionnaire

Background

On April 1, 2016, the Ministerial ordinance was enforced, and musculoskeletal examination of the extremities was made mandatory. From 2008, the University of us started musculoskeletal direct examination. To expand the examination, from 2016, we started to use the marksheet-type questionnaire. This study aimed to report the results of a musculoskeletal examination and investigate the association between musculoskeletal examination and age/gender and reports the reliability of the collected questionnaire data.

A new end graft holder for coronary artery bypass grafting.

This article describes the construction and use of a new end graft holder during coronary artery bypass grafting (CABG). The instrument consists of a pinching device attached to a flexible arm and a fixation clamp. This device provides secure stabilization and enables excellent positioning of the graft without producing graft injury.     

Purification and characterization of aplysianin E, an antitumor factor from sea hare eggs

An antitumor factor, aplysianin E, inducing tumor lysis was purified to apparent homogeneity from the supernatant of a homogenate of eggs of the sea hare Aplysia kurodai. Purified aplysianin E was a 250-kDa glycoprotein containing three different subunits. This factor was half-maximally active at 2-114 ng protein/ml and lysed all the tumor cells tested but did not lyse normal white or red blood cells. Aplysianin E was labile on treatments with heat, low pH, urea, guanidine, sodium lauryl sulfate, and periodate, but not with proteases or organic solvents, Aplysianin E completely inhibited the syntheses of DNA, RNA, and protein by tumor cells within 2 h and caused their complete cytolysis within 15 h. Tumor lysis by aplysianin E was inhibited by N-acetylneuraminic acid, suggesting that recognition of the sugar moiety is a key step in cytolysis induced by aplysianin E. Aplysianin E also prolonged the survival of mice bearing syngeneic MM46 ascites or solid tumors. These results suggest that aplysianin E, found in an invertebrate, the sea hare, is a new antitumor factor.     

Antibodies to brain proteins in paraneoplastic cerebellar degeneration

A 68-year-old man had subacute cerebellar degeneration and a non-Hodgkin's lymphoma. Using an immunoblotting method, we found serum antibodies to rat cerebral 250-kd and 110-kd and cerebellar 110-kd acidic cytoplasmic proteins. The antibodies did not react unless the antigens were prepared soon after death with protease inhibitors. Two hundred fifty-kd and 110-kd proteins are minor components of soluble cytoplasmic proteins of the brain. The molecular weights differed from other soluble brain-specific proteins already characterized.     

A case of humidifier lung associated with BHL]

We encountered a rare case of hypersensitivity pneumonitis associated with bilateral hilar lymphadenopathy (BHL). The patient was a 53-year-old male, who developed dry cough and shortness of breath when using a humidifier since 1982. He was admitted to our hospital for further evaluation in 1987. Chest X-ray films showed BHL and ground glass appearance in the bilateral lung fields. Pulmonary function test indicated disturbance of diffusing capacity. Transbronchial lung biopsy revealed interstitial pneumonitis, and lymph node biopsy by mediastinoscopy showed lymphoid sinus histiocytosis without noncaseating granuloma. Provocation test using the humidifier was positive, and the diagnosis of humidifier lung with BHL was made.     

Replantation of the distal part of the leg

We successfully replanted five amputated legs in five patients and followed the patients for two years or more (average, six years and three months). Although some patients found it impossible to squat and to run because of joint contractures, muscle weakness, or deformities of the foot, all patients could perform other activities without difficulty. None had important pain or any intolerance to cold, and all were satisfied with the results of the replantation.
