[A case report: mucinous carcinoma of prostate].

We present a case of mucinous carcinoma of prostate. A 64-year-old man visited our hospital because of high score of prostate specific antigen (PSA). Prostatic biopsies were performed twice, but cancer was not found.

[A case of retroperitoneal mucinous cystadenocarcinoma].

A 61-year-old woman was admitted to our hospital for right abdominal mass. Various examinations revealed a retroperitoneal tumor. Open surgery was performed.

[A case report: an urethral tumor with cavernous structure developed after optical urethrotomy].

A 70-year-old man underwent transurethral resection of the prostate (TURP) in February 1999 and he received optical urethrotomy because of urethral stricture in May. In May 2000, a distal urethral tumor was found by urethroscopy. Endoscopic resection of the urethral tumor was performed.

[Utility of SPECT in gallium scintigraphy].

Whole-body gallium planar scintigraphy is a mainstay for the detection of tumors and inflammatory lesions. Recently, gallium SPECT (single photon emission computed tomography) has become more common in the clinical setting. This diagnostic modality is widely employed in our hospital, and lesions are actually detected by SPECT in some cases.

Bone scintigraphy screening for osteonecrosis of the shoulder in patients with non-traumatic osteonecrosis of the femoral head.

Objective: In patients with non-traumatic osteonecrosis of the femoral head (ONFH), the shoulder is one of the major affected sites secondary to the proximal and distal femur in cases of multiple osteonecrosis. The present study attempted to investigate whether technetium bone scintigraphy is useful for screening of non-traumatic osteonecrosis of the shoulder (ONS).

Design And Patients: A total of 170 shoulder joints in 85 patients with ONFH were evaluated by bone scintigraphy and the findings compared with those of magnetic resonance imaging (MRI).

[A case of mucinous cystadenocarcinoma of the appendix penetrating the urinary bladder].

The patient, an 81-year-old woman, had the chief complaint of macroscopic hematuria. Cystoscopy revealed a bladder tumor, which was determined by biopsy to be mucin-producing adenocarcinoma. Appendiceal carcinoma that invaded the bladder were diagnosed preoperatively by air-contract barium enema and magnetic resonance.

Sciatic nerve palsy after cementless total hip arthroplasty. Treatment by modular neck and calcar shortening: a case report.

This is a case report of sciatic nerve palsy after total hip arthroplasty. Although the patient's symptoms became worse postoperatively, full recovery occurred after shortening of the calcar and femoral neck length. For acute sciatic nerve palsy patients with worsening of symptoms in the postoperative course in spite of hip and knee flexion, reexposure for early recognition of the sciatic nerve condition and reoperation by shortening the femoral neck may be an option.

Femoral anteversion, femoral offset, and abductor lever arm after total hip arthroplasty using a modular femoral neck system.

We studied the effectiveness of a modular femoral neck system for the adjustment of femoral anteversion, femoral offset, and abductor lever arm during total hip arthroplasty (THA) using computed tomography data, and comparing findings in patients with a modular neck femoral component (116 hips) with those in patients with a cemented femoral component (23 hips). In the modular neck group, we intraoperatively evaluated various impingements using trial necks and heads, and selected the appropriate combination of modular neck and head from two types of straight neck, four types of anteverted/retroverted neck, two types of medialized/lateralized neck, and two types of varus/valgus neck. In the cement group, femoral anteversion was not changed using undersized stems, and an appropriate modular head was selected.

[Brain infarction related to hepatic arterial infusion chemotherapy].

We examined the occurrence of brain infarction with hepatic arterial infusion chemotherapy for liver cancer. One hundred and eighty-one cases of hepatic arterial infusion chemotherapy were carried out for liver cancer patients in 4 hospitals associated with Osaka University 2nd Dept. of Surgery.

[Usefulness of 99mTc-methoxy-isobutyl-isonitrile scintigraphy for preoperative localization of adenoma in primary hyperparathyroidism].

We evaluated the usefulness of 99mTc-methoxy-isobutyl-isonitrile (MIBI) dual phase scintigraphy for detecting hyperfunctioning parathyroid adenoma. We retrospectively reviewed 18 hyperparathyroid patients who received MIBI prior to neck exploration and compared the radiological findings of MIBI with ultrasonography (US) and magnetic resonance imaging (MRI). Fifteen patients were studied with MRI, and 17 patients were examined with US.

Combined hepatocellular/cholangiocellular carcinoma with sarcomatoid features: genetic analysis for histogenesis.

The histogenesis of sarcomatoid transformation in hepatocellular carcinomas (HCCs) and cholangiocellular carcinomas (CCCs) remains unclear. In the current case, microsatellite loss of heterozygosity (LOH) assay and mutational analysis of the p53 gene with immunohistochemical examination were performed to investigate the histogenesis of each component. The tumor was composed of two parts: one part comprised poorly differentiated HCC (HCC portion), while the other part included undifferentiated, sarcomatoid HCC and CCC (combined portion).

Accumulation of beta-catenin in the cytoplasm and the nuclei during the early hepatic tumorigenesis.

Hepatocellular carcinomas (HCCs) are thought to develop as well-differentiated tumors and progress to less-differentiated tumors. However, the genetic changes underlying the development and progression of HCCs are not well understood. Recent studies have shown frequent beta-catenin gene activation in HCCs by somatic alterations involving exon 3, resulting in the activation of the Wnt/Wingless signal transduction pathway.
