Ventilator-associated events: prevalence and mortality in Japan.

Background: In 2013, the Centers for Disease Control and Prevention (CDC) issued the concept of the ventilator-associated events (VAEs) as a quality indicator (QI) in the intensive care unit (ICU). A number of studies have been conducted in the United States and other Western countries to evaluate its practicality. However, information on VAEs in non-Western countries is scarce.

Prostate cancer with cyst formation detected by whole body positron emission tomography/computed tomography: A case report.

The present study reports a case of prostate adenocarcinoma with cyst formation. A 72-year-old male diagnosed with multiple lung metastases at a local clinic was referred to Tokai University Hachioji Hospital (Tokyo, Japan) for detection of a primary lesion. Whole body positron emission tomography/computed tomography showed strong accumulation of [F]-fluoro-deoxy-2-glucose (FDG) in the small pelvis, and pelvic magnetic resonance imaging revealed a 60×40-mm cystic lesion, with an irregular thickened wall, behind the prostate.

[A case of laparoscopic radical nephrectomy in right renal cell carcinoma with left inferior vena cava].

We present a case of laparoscopic radical nephrectomy in right renal cell carcinoma with left inferior vena cava in a 65-year-old male. Abdominal contrasted CT scan revealed that the left inferior vena cava crossed the aorta at the level of third lumbar vertebra. Laparoscopic radical nephrectomy was performed transperitoneally.

[Extraskeletal myxoid chondrosarcoma of the left iliopsoas muscle].

A 62-year-old man was referred to our hospital with a 10 cm retroperitoneal tumor, which was incidentally found on the abdominal computed tomography (CT). CT-guided percutaneous needle biopsy revealed that the tumor was malignant, but could not define the exact pathology of the tumor. The tumor was resected.

[Renal infarction with renal abscess onset due to infective endocarditis: a case report].

A 68- year-old male was referred with fever and urinary tract infection. Abdominal computed tomography showed a right renal infarction with abscess and abscesses in the liver and spleen. Cardiac ultrasonic examination showed a vegitation in the aortic valve.

Metastin inhibits migration and invasion of renal cell carcinoma with overexpression of metastin receptor.

Background: Metastin, the final peptide of the KiSS-1 gene, has been proposed to suppress cell motility.

Objective: This study investigated whether renal cell carcinoma (RCC) tissue expresses metastin or its receptor, and clarified whether metastin can suppress migration and/or invasion and/or proliferation of RCC cells in vitro.

Design, Setting, And Participants: Twenty-five RCC samples were submitted.

Castleman's disease in the pararenal retroperitoneal space, which is indistinguishable from renal cell carcinoma: a case report.

A 29-year-old woman was hospitalized in our institute with the diagnosis of a right renal mass by ultrasonography on medical checkup. Computerized tomography showed a lower pole solid mass (9 cm in diameter), which was enhanced homogeneously, as well as the renal cortex in the arterial phase. The tumor was excised using radical nephrectomy based on the preoperative diagnosis of renal cell carcinoma, and thus lymph node dissection was also performed.

[Clinical evaluation of postoperative urinary incontinence after laparoscopic radical prostatectomy: "cross sectional study based on the original questionnaire"].

A cross-sectional study for certain symptoms of postoperative incontinence was done for patients who underwent laparoscopic radical prostatectomy (LRP) using our original self-administered questionnaire. A total of 104 patients, who underwent LRP from April 2002 to March 2005 in our institute and related hospitals, participated in our questionnaire study. Mean age and median observation period was 64.

Evaluation of renal function after laparoscopic partial nephrectomy with renal scintigraphy using 99mtechnetium-mercaptoacetyltriglycine.

Aim: We evaluated the functions of an affected kidney after laparoscopic partial nephrectomy (LPN) using renal scintigraphy with (99m)technetium-mercaptoacetyltriglycine ((99m)Tc-MAG3).

Methods: Split renal function of 10 patients who underwent LPN for renal tumors was assessed using renal scintigraphy with (99m)Tc-MAG3 before surgery, and 1 week and 3 months post-surgery.

Results: Median operating time was 196.

Acute myocardial infarction during combined chemotherapy with bleomycin, etoposide and cisplatin for testicular cancer.

We report a case of acute myocardial infarction during combined chemotherapy with bleomycin, etoposide and cisplatin for testicular cancer. A 30-year-old smoker without any history of ischemic heart disease complained of sudden chest pain on the ninth day of his third course of chemotherapy. An electrocardiogram showed ST segment elevation in II, III and aVF.

[Sepsis following transrectal prostate biopsy: a report of 2 cases and reviewed similar cases in Japan].

We report two cases of sepsis and disseminated intravascular coagulation (DIC), potentially fatal complications, following transrectal prostate biopsy. We also review similar cases reported in Japan. Case 1: A 63-year-old man received a cathartic and levofloxacin (LVFX) for prophylaxis.

[A case report: simultaneous bilateral testicular tumors with different cell types--complete response after combination chemotherapy of cisplatin and irrinotecan hydrochloride--].

A 38-year-old man was admitted to our hospital complaining of bilateral scrotal swelling. On examination, the patient was found to have bilateral testicular tumors with jugular chain lymph node and para-aortic lymph node metastasis. He underwent bilateral inguinal orchiectomy.

Screening program of prostate cancer at Tokai University Hospital: characterization of prostate-specific antigen measurement.

A total of 67,214 men participated in screening for prostate cancer (PC) using serum prostate-specific antigen (PSA) from April 1996 to March 2003 at Tokai University Hospital. In 3.5% (2330 / 67,214) of the men, an elevated PSA level (> 4.

Association of neuroendocrine differentiation with neoadjuvant hormone therapy effects in prostatic cancer.

Histological therapeutic effects of neoadjuvant hormone therapy (NHT) in prostatic cancer were examined, focusing on the association with neuroendocrine differentiation (NED), using 69 radical prostatectomy cases. The effects of NHT were classified into 3 grades based on the extent of tumor degeneration as observed with hematoxylin and eosin staining. NED cells in the cancer were semi-quantified into 4 grades (negative, 1+, 2+, and 3+) by immunohistochemical staining of chromogranin A (CgA).

[Metastatic small intestinal tumor associated with transitional cell carcinoma: a report of 2 cases and review of cases in Japan].

Transitional cell carcinoma (TCC) frequently metastasizes to lymph nodes, liver, lungs and bone. However, metastasis to the gastrointestinal tract is rare. We report two cases of bladder tumor which metastasized to the ileum.

Urolithiasis in geriatric patients.

Objectives: We intended to find risk factors for urolitiasis and its recurrence in a geriatric population.

Patients And Methods: The medical records of 209 elderly stone patients over age 65 were reviewed. They had been regularly seen at our stone clinic for a mean follow-up period of 1385 +/- 1324 days after urolithiasis was diagnosed.

Urinary citrate in kidney stone disease.

Background: Hypocitraturia, or low urinary citrate excretion is known as a risk for nephrolithiasis. Though urinary citrate excretion is basically determined by acid-base balance, metabolic acidosis is not always manifest in urinary stone patients with hypocitraturia. From our stone clinic data, we estimated the incidence of hypocitraturia and addressed its causes in the absence of obvious acid-base imbalance.
