CT-guided mapping in the removal of an impalpable, radiopaque foreign body in subcutaneous tissue: a case report.

Small fragments sometimes penetrate the soft tissue, and their depth and location can be difficult to determine accurately. This case study describes localisation of a thin, short wire that had penetrated the soft tissue of a 24-year-old man's back, using computed tomography (CT) with a reference grid made with an angiographic catheter. The axial non-contrast-enhanced CT scan with the grid placed over the affected body part surveyed by the CT scout view showed that the foreign body was buried in fascia 7cm from a puncture wound.

Dislocation of temporomandibular joint: complication of sagittal split ramus osteotomy.

Sagittal split ramus osteotomy (SSRO) has wide-ranging indications and results in simultaneous improvements in occlusion and facial appearance. Thus, it is the most frequently used osteotomy for jaw deformities. Its main intraoperative and postoperative complications are massive bleeding, atypical fractures, inferior alveolar nerve paralysis, and relapse.

Poor performance status is a strong predictor for death in patients with smear-positive pulmonary TB admitted to two Japanese hospitals.

Background: Estimation of performance status (PS) has been assessed as a tool to determine which patients with newly diagnosed pulmonary TB (PTB) are most at risk of dying. This simple prediction rule has not been validated in patients with PTB with different background characteristics and from different geographic areas.

Methods: A retrospective cohort study was conducted in two Japanese hospitals in different regions and included 432 inpatients with newly diagnosed smear-positive non-multidrug-resistant lung TB without HIV infection.

Comparison of lymphoscintigraphy and indocyanine green lymphography for the diagnosis of extremity lymphoedema.

Background: Lymphoscintigraphy is the gold-standard examination for extremity lymphoedema. Indocyanine green lymphography may be useful for diagnosis as well. We compared the utility of these two examination methods for patients with suspected extremity lymphoedema and for those in whom surgical treatment of lymphoedema was under consideration.

Early diagnosis and risk factors for lymphedema following lymph node dissection for gynecologic cancer.

Background: Although early diagnosis is important for selecting an effective surgical treatment for secondary lymphedema, an efficient screening test for detecting early-stage lymphedema has not yet been established. Serial changes of lymphatic function before and after lymph node dissection and risk factors for secondary lymphedema are important indicators.

Methods: A prospective cohort observational study was conducted with 100 consecutive gynecologic cancer patients who underwent pelvic lymph node dissection.

The presence of pretreatment cavitations and the bacterial load on smears predict tuberculosis infectivity negative conversion judged on sputum smear or culture.

Objective: There are no rules to predict the time to infectivity negative conversion based on sputum smear conversion or culture conversion during chemotherapy in smear-positive tuberculosis patients. We aimed to develop and validate rules of sputum smear grades and cavitations in the lungs due to tuberculosis.

Methods: This study was a retrospective cohort study that consisted of development (n=158, 64 ± 19 years of age) and validation (n=214, 63 ± 20 years of age) steps in different cohorts.

Gas-producing cellulitis from injection of spot remover fluid (n-Hexane).

Background: Subcutaneous administration of hydrocarbons, categorized according to their toxicological profiles, is rare compared to oral, inhalational, and cutaneous routes of exposure. Furthermore, injection of n-hexane in humans has not been described.

Objectives: This report demonstrates a singular case of subcutaneous administration of n-hexane.

Reconstruction of a contracted eye socket using an anterofrontal superficial temporal artery island flap and scapha composite grafting in an elderly patient.

There are numerous methods for reconstruction of the eye socket. However, the use of an island flap on the forehead based on the anterofrontal branch of the superficial temporal artery has not been reported upon. This article describes an experience of eye-socket reconstruction in a 90-year-old woman with an anterofrontal superficial temporal artery island flap, a temporoparietal fascia flap and scapha composite grafting in a one-step procedure.

Cryoprotective activity of mannoprotein from the cell membrane of Pichia anomala.

Some organisms like bacteria and plants have a cryoprotective protein to cryopreserve the freeze-labile enzyme under stable conditions having high activity. By screening of the cryoprotective activities of various food-industrial yeasts, we found that the cell membrane component that was a glucanase extractable component in Pichia anomala NBRC 141 had a high level of cryoprotective activity against freeze-labile lactate dehydrogenase (LDH). The absorption of the active compound in the crude extract by ConA-Sepharose chromatography suggested that this active compound might be a glycoprotein (COGP).

Polychlorinated biphenyls alter the expression of endothelial nitric oxide synthase mRNA in human umbilical vein endothelial cells.

Polychlorinated biphenyls (PCBs) are a group of persistent pollutants that are detected in maternal serum and umbilical cord, suggesting that fetal exposure also needs to be considered. The effects of dioxin-like PCB congeners 3,3',4,4'-tetrachlorobiphenyl (PCB77) and 3,3',4,4',5-pentachlorobiphenyl (PCB126) and a non-dioxin-like compound 2,2',4,4',5,5'-hexachlorobiphenyl (PCB153) on the expression of endothelial nitric oxide synthase (eNOS), known to maintain blood flow to the fetus, in human umbilical vein endothelial cells (HUVECs) were investigated. The mRNA levels of eNOS, aryl hydrocarbon receptor (AhR) and cytochrome P450 (CYP) 1A1 in cells treated with 5 microM PCBs for 24 hours were analysed by real-time RT-PCR.
