Propane dehydrogenation catalysis of group IIIB and IVB metal hydrides.

Catalytic propane dehydrogenation (PDH) has mainly been studied using metal- and metal oxide-based catalysts. Studies on dehydrogenation catalysis by metal hydrides, however, have rarely been reported. In this study, PDH reactions using group IIIB and IVB metal hydride catalysts were investigated under relatively low-temperature conditions of 450 °C.

Association of schizophrenia with fracture-related femoral neck displacement: A cross-sectional retrospective study.

Aim: Fracture-related femoral neck displacement is more likely in patients with schizophrenia because of delayed diagnosis, as these patients frequently have less severe fracture-associated subjective symptoms. This study aimed to investigate the association of schizophrenia with the risk of fracture-related femoral neck displacement in hospitalized patients.

Methods: We retrospectively analyzed the medical records of patients with femoral neck fractures treated between April 2013 and March 2018 at a single institution.

Rapid and sensitive detection of elephant endotheliotropic herpesvirus 1 (EEHV1) in blood by loop-mediated isothermal amplification (LAMP).

Elephant endotheliotropic herpesvirus type 1 (EEHV1) is the most important causative agent of an acute fatal hemorrhagic disease in Asian elephants (Elephas maximus). We employed loop-mediated isothermal amplification (LAMP) to develop a rapid and simple detection method for EEHV1 in blood. When used to test 21 clinical samples collected in Japan, the EEHV1 assay correctly identified one positive and 20 negative clinical samples.

[Penile Tuberculosis : A Case Report].

A 66-year-old man presented with a chief complaint of glans penis pain, induration, and discharge of pus. He was prescribed a course of antibiotics, but the condition persisted despite treatment. Thus, we differrentially diagnosed the patient with penile tuberculosis and pyoderma gangrenosum, and performed a biopsy of the penis.

Modification of the impact of hypertension on proteinuria by renal arteriolar hyalinosis in nonnephrotic chronic kidney disease.

Objective: Morphological analysis suggests that afferent arteriole hyalinosis reflects disturbed autoregulation of glomerular hemodynamics. However, the effect of arteriolar hyalinosis on the correlation between blood pressure (BP) levels and proteinuria is unknown in patients with chronic kidney disease (CKD). Therefore, we conducted a cross-sectional study to determine this correlation.

[A case of giant testicular tumor in a schizophrenic patient].

A 55-year-old man with schizophrenia presented with right scrotal enlargement. Clinical examination revealed a right adult -head-sized testicular tumor, multiple lymph node metastasis with marked elevation of serum lactic dehydrogenase (LDH) and β -human chorionic gonadotropin (β -HCG). Right high orchiectomy followed by chemotherapy with bleomysin, etoposide and cisplatin (BEP) for 4 cycles was performed.

Interrelationship between brachial artery function and renal small artery sclerosis in chronic kidney disease.

Chronic kidney disease (CKD), characterized by senile inflammation, is a risk factor for cardiovascular disease. Conduit artery function and small artery structure relate to cardiovascular disease. We examined the correlations, determinants and interrelationships of arterial indices in association with CKD in a cross-sectional study of 139 patients (60% male; mean age 44 years) with CKD (stages 3-5, 39%) who underwent a renal biopsy.

Endometriosis and pregnancy outcome: are pregnancies complicated by endometriosis a high-risk group?

Objectives: Increased incidence of preterm birth, pregnancy-induced hypertension (PIH) and small-for-gestational-age (SGA) babies have been reported in women with endometriosis, but the study populations included women in whom a definitive diagnosis was not attainable, and women who conceived via in vitro fertilization/embryo transfer (IVF/ET), which, in itself, is a risk factor for adverse pregnancy outcome. Thus there is a lack of consensus on the effects of endometriosis on pregnancy outcome. This study compared the pregnancy outcomes of women with or without a definitive diagnosis of endometriosis on laparoscopy.

[A case of metabolic acidosis and tetany after ileal neobladder replacement].

A 64-year-old man visited our hospital with the complaint of macrohematuria and bilateral hydronephrosis. He had undergone total cystectomy and ileal neobladder replacement under the diagnosis of muscle invasive bladder cancer (cT2bN0M0). Tetany due to hyperventilation syndrome appeared on postoperative day 42.

Hypertriglyceridemia accompanied by increased serum complement component 3 and proteinuria in non-nephrotic chronic kidney disease.

Background: Hypertriglyceridemia (hTG) is a risk factor for progression of chronic kidney disease (CKD); however, it remains unknown whether the adipocytokine complement component 3 (C3) is involved in the association between hTG and CKD.

Methods: The study included 138 patients (54 % male) with non-nephrotic (serum albumin ≥3 g/dl) CKD who had undergone a renal biopsy and did not have hypocomplementemic disease. Renal arteriolopathy was assessed semi-quantitatively.

[IgG4-related idiopathic segmental ureteritis which was difficult to distinguish from ureteral cancer: a case report].

A 79-year-old woman was admitted with a chief complaint of gross hematuria, pollakisuria, lower abdominal pain. Urine cytology, intravenous pyelography, and cystoscopy were performed but showed no abnormal findings. About 6 months later, abdominal computed tomography (CT) revealed a 5cm long segment of ureteral narrowing with wall thickening, hydronephrosis, para-aortic lymph node swelling.

Acute phlegmonous esophagitis as a rare but threatening complication of chemoradiotherapy: report of a case.

Phlegmonous infection involving the digestive tract has been reported to have a poor prognosis. However, the pathogenesis and clinical features of acute phlegmonous esophagitis have remained unclear due to the rarity of the disease. We herein report a case of acute phlegmonous esophagitis that showed a fulminant course during chemoradiotherapy for uterine cancer.

An association between uric acid levels and renal arteriolopathy in chronic kidney disease: a biopsy-based study.

Uric acid (UA) can induce renal arteriolopathy in animal models. Whether there is an association between UA and renal arteriolopathy in patients with chronic kidney disease (CKD) is unknown. Here, we examined the cross-sectional association of serum UA levels with renal arteriolar hyalinosis and wall thickening.

Shoulder surface temperature and bone scintigraphy findings in patients with rotator cuff tears.

Background: Complex regional pain syndrome (CRPS) is one of the serious complications after surgical treatment of a rotator cuff tear. Both a measurement of body surface temperature and bone scintigraphy have been used as diagnostic tools for the early phase of CRPS.Unfortunately, few studies have been carried out that applied these methods to the patients after rotator cuff repair.

Since May 1992, we have performed percutaneous transluminal angioplasty (PTA) or stenting 70 times for 65 lesions in 62 patients with atherosclerotic stenosis of the intracranial or skull base cerebral arteries. Stenting was carried out nine times for nine lesions in nine cases. Stenting was performed on patients with an average age of 62.

[Schwannoma of the cervical spinal cord with cervical angina: a case report].

A case of schwannoma of the cervical spinal cord presenting with cervical angina is reported. A 49-year-old man was admitted to our hospital with severe chest pain, cold sweats, and unconsciousness. Extensive cardiac examination showed no abnormal findings.

Large eventration of diaphragm in an elderly patient treated with emergency plication.

Total eventration of the hemidiaphragm is a rare condition in adults. We report a 75-year-old woman with large eventration of the right diaphragm who required an emergency plication because of acute progressive respiratory distress. The symptom disappeared immediately after operation.

[Temporary extracorporeal axillofemoral venous bypass--a beneficial device in operation for superior vena caval syndrome due to intrathoracic malignancies].

Life-threatening complications can occur unexpectedly during general anesthesia in operations for superior vena caval (SVC) syndrome due to intrathoracic tumors. To prevent such sequelae, we have placed a temporary extracorporeal axillofemoral venous bypass graft with satisfactory results. In six patients (malignant mediastinal tumor, four; lung cancer, two), under local anesthesia before induction of general one, the cannulas, each appropriately sized in accordance with the diameter of the axillary and femoral veins, were directly introduced into the corresponding veins after systemic heparinization.
