The possibility using a solar battery as a power source for the electrochemical disinfection of microorganisms was examined. A single solar battery with an open circuit voltage 20 V and a capacity of 1 A was used for laboratory scale-examination. The electrochemical disinfection cell containing palladium-coated carbon cloth electrodes was reported previously and a dominant parameter on the disinfection was found to be the concentration of chloride ions. The concentration of NaCl as a source of chloride ions was varied from 0.154 mol dm -3 (saline solution) to 0.00154 mol dm -3 (the concentration being four to ten times that of NaCl in tap water in Tokyo) in this study. Disinfection was examined in only one flow-passage of the microorganisms' suspension across the electrolytic cell. Escherichia coli was selected as a model microorganism. Disinfection under a clear sky was complete, and was almost complete even under an obscured sky. The viability of E. coli at a current of 100 mA was less than 1 × 10 -6 irrespective of the concentration of NaCl. The viability of E. coli at a current of 50 mA increased to 0.001 in the suspension containing 0.00154 mol dm -3 of NaCl.

The endoscope is one of the most extensively used medical devices. Endoscopes are deterged with extreme care because they are inserted directly in the body. Electrochemical disinfection using a palladium-coated carbon cloth electrode was applied to deterge a rod-shaped tool as a potential endoscope-deterging method because It required no toxic agent, did not cause secondary pollution, and provided an eco-friendly disinfection system. The anodic polarization of palladium in an NaCI-containing solution led to the effective generation of disinfective CIO" and the simultaneous gas evolution caused natural convection that Increased the disinfection efficacy. Electrochemical degreasing could also be attained by alternating between positive and negative electrode polarities. © The Electrochemical Society of Japan. All rights reserved.

Although techniques for autoreduction of anterior shoulder dislocation have been developed, no reports have detailed an autoreduction method using the zero position and traction on the affected arm. Therefore, we developed a new autoreduction technique using the zero position and gentle autotraction. The objective of this study is to present our experiencewith a newmethod for autoreduction of anterior shoulder dislocation called the GONAIS (a backronym for "Grasp a waist-high object, Opposite arm assists, Nonsedated, Autoreduction/autotraction, Immobilize the grasped object, and Squatting and stooping") method. A 41-year-old healthy woman with a history of left shoulder dislocation presented to the emergency department with left shoulder pain while attaching her seatbelt. The X-ray examination revealed subcoracoid dislocation of the left shoulder. The patient tried the GONAIS method after simple guidance and demonstration. Although she felt pain once when weakening traction, she achieved autoreduction successfully in only 2min and 50 s. Clinical examination after autoreduction revealed normal neurovascular findings and appearance of the shoulder. The X-ray revealed glenohumeral joint reduction and no fracture. Here, our patient using the GONAIS method achieved shoulder autoreduction in a short time. The GONAIS method does not require lying down or sitting on the ground, does not necessarily require the opposite arm, and is minimally invasive. This method would likely be helpful for those who cannot quickly reach a hospital for treatment of anterior shoulder dislocation. © 2015 Elsevier Inc. All rights reserved.

Objective: Cerebrospinal fluid (CSF) shunts are frequently used to treat hydrocephalus. The use of a programmable valve allows the operator to easily change the opening pressure. In Japan, many people use magnetic Induction therapy apparatuses in their homes. However, - exposing patients with adjustable CSF shunt valves to the permanent magnets included in these apparatuses may alter the shunt valve's programmed settings or permanently damage the device. Therefore, the goal of this study was to determine the health risk associated with magnetic induction therapy for patients using programmable CSF shunt valves. Methods: Five models of shunt valves from five different manufacturers, the Miethke proGAV (proGAV), the Codman Hakim programmable valve (CHPV), Sophysa Sophy model SM8 (Sophy valve), Sophysa Polaris model SPV (Polaris valve), and Strata II valve (Strata valve) were evaluated in this study. Magnetic field interactions were determined for the programmable valves by using magnetic stones with various magnetic flux densities. The maximum distance between the valve and the magnetic stone affecting the valve pressure setting was measured by X-ray. Results: The proGAV and Polaris valve were immune to unintentional reprogramming by the magnetic stones. The CHPV, Sophy valve and Strata valve, however, randomly changed settings by magnetic stones. Conclusions: Whereas the CHPV. Sophy valve and Strata valve were promptly reset by exposure to a magnetic stone with a similar strength to that used in magnetic induction therapy, proGAV and Polaris valve were resistant to inadvertent reprogramming when exposed to magnets up to 190 mT.

A 61-year-old man with a history of esophageal carcinoma operated one year before was admitted to our hospital because of left hemiparesis including face. MRI revealed a cystic mass with a solid nodule in the right parietal lobe. The cyst was hypointense on T1-wighted images of MRI, with markedly enhancing rim after Gd injection. On T2-weighted images, the cyst was hyperintense, and the solid portion appeared to be heterogeneous. Based on the patient's past history, a metastatic brain tumor from esophageal carcinoma was suspected. A parietal craniotomy was performed, and the tumor was completely excised macroscopically. Histological diagnosis was a moderately differentiated squamous cell carcinoma, confirming our preliminary diagnosis. The patient had a good postoperative course, with complete resolution of his symptoms. Brain metastases from esophageal carcinoma are relatively rare, and little information is available on the clinical course and radiological findings. Here we report clinical and radiological features of brain metastasis from esophageal carcinoma focusing on MRI findings, with review of the literature.
