Laparoscopic transabdominal preperitoneal hernioplasty for recurrent obturator hernia: A case report.

Reports of recurrence after obturator hernia repair are few. We describe the case of an 89-year-old woman who presented to us with a thrice recurrent obturator hernia. She had undergone open non-mesh repair twice and then laparoscopic non-mesh repair.

Primary extraskeletal osteosarcoma of the mesentery: A case report.

Introduction: Extraskeletal osteosarcoma is a rare malignant soft tissue tumor without attachment to the bone. To the best of our knowledge, we present here the first report of a primary extraskeletal osteosarcoma of the mesentery in Japan.

Case Presentation: A 46-year-old female underwent a health examination, with no complaint.

Cardiac tolerability of concurrent administration of trastuzumab and anthracycline-based regimen as adjuvant chemotherapy for breast cancer.

Background: Retrospective analysis suggests that anthracycline-containing regimens may be superior to non-anthracycline-containing regimens in patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer. However, both trastuzumab and anthracycline have cardiotoxicity, and it remains unclear how to use trastuzumab in combination with an anthracycline to curtail their cardiotoxicity.

Patients And Methods: From 2010 to 2013, we administered weekly (q1w) paclitaxel (wP) followed by 75 mg/m(2) epirubicin, fluorouracil, and cyclophosphamide (FEC) every third week (q3w) and concurrent q1w trastuzumab (H) to 41 patients with HER2-positive breast cancer (H+ group), and wP followed by FEC100 without trastuzumab to 57 patients who were HER2-negative (H- group).

[Marginal zone lymphoma of mucosa-associated lymphoid tissue of the parietal pleura; report of a case].

An 76-year-old man was referred to our hospital due to right hydrothorax. The diffuse thickening of parietal pleura with increased fluoro-2-deoxy-D-glucose (FDG) uptake was noted by computed tomography (CT) and positron emission tomography (PET). Surgical biopsy was performed and the tumor was diagnosed as mucosal associated lymphoid tissue (MALT) lymphomas of parietal pleura origin by pathology.

[Lymphoepithelioma-like carcinoma（ LELC） of the lung].

A 77-year-old woman was admitted to our hospital with abnormal chest shadow detected on a medical checkup. Chest computed tomography(CT)showed a well-defined tumor in the upper lobe of the right lung. On positron emission tomography by fluorodeoxyglucose(FDG),the tumor revealed to be positive.

[Sarcoidosis with right middle lobe atelectasis initially suspected of malignant lymphoma; report of a case].

60-year-old woman was admitted with an abnormal shadow on the chest roentgenogram. Computed tomography showed atelectasis of the right middle lobe and hilar and mediastinal lymphadenopathy. Bronchoscopic examination revealed an obstruction at the orifice of the right middle lobe bronchus and biopsy was performed.

[Human pulmonary dirofilariasis].

The patient was a 60's-year-old man, who was incidentally pointed out a coin lesion in the right lung by chest radiogram. Chest computed tomography showed a round-shaped, well defined nodule of 2.5 cm in size in the right S1.

[Adult Bochdalek hernia combined with pneumothorax].

A 71-year-old man, who had been given a diagnosis of Bochdalek hernia in infancy, was referred to our hospital for dyspnea The chest X-ray and computed tomography (CT) showed left pneumothorax with bullas and intestines in his left thoracic cavity. He was admitted to our hospital and a chest tube was inserted into the left pleural cavity. The left lung expanded immediately and air leakage was stopped.

Inhibition of replication induces non-apoptotic cell death in fibroblast cell lines derived from LEC rats.

Hydroxyurea (HU), an anticancer drug, inhibits ribonucleoside diphosphate reductase and reduces pool sizes of deoxyribonucleoside triphosphate (dNTP). The reduction of dNTP results in inhibition of DNA replication. The cytotoxic effect of HU was investigated using fibroblast cell lines from LEC rats.
