A case of incomplete duplication of the portal vein associated with multiple congenital anomalies.

Double portal veins are a duplication of the portal vein and normal portal vein with an accessory portal vein. We report a case of a 63-year-old asymptomatic female with double portal veins. There was fat accumulation observed in the area which was supplied by the first portal vein in normal position, and fatty sparing of the liver was observed in the area which was supplied by the second portal vein in the preduodenal position.

A prospective observational study of postoperative adjuvant chemotherapy for non-small cell lung cancer in elderly patients (≥ 75 years).

Background: To examine the effects of postoperative adjuvant chemotherapy for elderly (≥ 75 years of age) patients with completely resected non-small cell lung cancer (NSCLC), we conducted a multi-institutional and prospective observational study.

Methods: Patients were recruited between January 2014 and December 2017, and assigned to two cohort groups based on the patients' choice either to receive postoperative adjuvant chemotherapy (Cohort B) or not (Cohort A). All the patients were observed for 2 years after enrollment.

Epidemiologic Research on Malformations Associated with Cleft Lip and Cleft Palate in Japan.

To investigate malformations associated with cleft lip and cleft palate, we conducted surveys at neonatal intensive care units (NICUs) and other non-NICU facilities and to determine whether there are differences among facilities. The regional survey investigated NICU facilities located in Oita Prefecture, including 92 patients with cleft lip and palate (CLP) or cleft palate (CP) that occurred between 2004 and 2013, and the national survey investigated oral surgery, plastic surgery, and obstetrics and gynecology facilities located in Japan, including 16,452 patients with cleft lip (CL), CLP, or CP that occurred since 2000. The incidence per 10,000 births was 4.

Case report of anti-transcription intermediary factor-1-γ/α antibody-positive dermatomyositis associated with gastric cancer and immunoglobulin G4-positive pulmonary inflammatory pseudotumor.

Dermatomyositis is a rare connective tissue disease often associated with internal malignancy and interstitial pneumonitis. Serologically, various auto-antibodies (Ab) are associated with dermatomyositis. Anti-transcription intermediary factor-1-γ/α (TIF-1-γ/α) Ab was recently identified as an auto-Ab and was observed mostly in cancer-associated dermatomyositis.

Rhabdomyolysis due to Multiple Wasp Stings.

Wasp sting is a relatively common arthropod assault, but is sometimes fatal because of anaphylaxis. Rhabdomyolysis is a serious condition, with destruction of striated muscles, and can be induced by various causes such as drugs, heart attacks, CRASH syndrome, and viper bites. Mass envenomation by multiple wasp stings can also cause rhabdomyolysis followed by acute renal failure, although it is extremely rare.

[A recurrence after surgery for colon cancer with metastases of the liver and periaortic lymph nodes, with CR achieved by using bevacizumab+mFOLFOX6].

We have experienced and report here a case of postoperative recurrence of colon cancer with metastases in the liver and the periaortic lymph nodes, where we attained CR through combination therapy with bevacizumab+mFOLFOX6. The patient was a male aged 65. He had already had cecal cancer, metastasis in the para-aortic lymph nodes, and multiple hepatic metastases.

Lipid extracted freeze-dried bank bone sterilized with low temperature plasma.

Ethylene oxide gas (EOG) is widely used for sterilization of freeze-dried bone. Recently EOG is regulated for clinical use because of cytotoxicity and environmental pollution concerns. Low Temperature Plasma Sterilization (LTPS) has no toxicity and mutagenicity working with a hydrogen peroxide gas plasma at 45 degrees centigrade.

[Prevention of infections in a case with myelodysplastic syndrome by an intermittent subcutaneous administration of G-CSF].

An 83-year-old male was admitted to our hospital because of pancytopenia and low grade fever on April 19, 1993. On admission, hematological data were as follows: WBC 1,000/microliters with 19% neutrophils, RBC 367 x 10(4)/microliters, Hb 9.5 g/dl and platelets 6.
