Giant cell arteritis without cranial manifestations caused mesenteric involvement: a case report.

Background: Giant cell arteritis (GCA) is a granulomatous vasculitis and targets large vessels with predominance for the aortic arch and the cranial branches. GCA with cranial symptoms shows headache, jaw claudication, and ophthalmologic symptoms and thus was previously called temporal arteritis. Recently, cases of GCA without cranial manifestations and extracranial GCA have been reported.

[A Resected Case of Castleman's Disease That Was Difficult to Diagnose Preoperatively].

A 70-year-old man was referred to our hospital and admitted after abdominal computed tomography(CT)examination revealed a tumor in the retroperitoneum. The specific blood test findings were poor, and surveillance CT demonstrated a wellcircumscribed, enhanced mass measuring 40mm with calcification behind the horizontal portion of the duodenum. The tumor presented with a slightly high signal in low signal, T2 in T1, and it showed a diffusion decrease in DWI; the simple abdominal MRIrevealed heterogeneous accumulation of SUVmax 3.

[Surgical Resection for Advanced Gastric Cancer with Portal Vein Tumor Embolus - Two Cases].

Gastric cancer with portal tumor embolus is rare and there is no definite strategy for its surgical resection. We report 2 cases ofgastric cancer with portal vein tumor embolus treated using gastrectomy and thrombectomy. Case 1: The patient was a 56- year-old man.

[Two Cases of Systemic Steroid Therapy for Hyperbilirubinemia after Right Hepatic Lobectomy of Liver Metastasis from Colorectal Cancer].

We report 2 cases of systemic steroid therapy for hyperbilirubinemia after right hepatic lobectomy for liver metastases from colorectal cancer.One of the patients was a 65-year-old man, diagnosed with transverse colon cancer with multiple liver metastases.After surgery for the primary lesion and chemotherapy(FOLFOX plus bevacizumab, FOLFIRI plus panitumumab), he underwent right hepatic lobectomy for the liver metastasis.

Efficacy of preoperative dexamethasone for postoperative nausea and vomiting after laparoscopic cholecystectomy: a large-scale, multicenter, randomized, double-blind, placebo-controlled trial in Japan.

Background: To assess the efficacy of preoperative dexamethasone for postoperative nausea and vomiting (PONV) after laparoscopic cholecystectomy (LC) in Japan.

Methods: A total of 270 patients at eight hospitals were randomized to receive dexamethasone 8 mg (n = 136) or placebo (n = 134) intravenously before LC. The primary endpoint was the degree of PONV and antiemetic requirements within 24 h after LC.

CT and MRI findings for Brunner's gland hamartoma: report of three cases.

Brunner's gland hamartoma (BGH) is an uncommon, benign, tumor-like lesion of the duodenum. Endoscopic diagnosis of larger BGH is sometimes difficult. We describe computed tomography (CT) and magnetic resonance imaging (MRI) findings for three patients with BGH.

Predicting prolonged hospital stay after laparoscopic cholecystectomy.

Introduction: Widespread application of laparoscopic cholecystectomy (LC) has resulted in a high complication rate and leads to prolonged hospital stays. This study aimed to investigate the preoperative and intraoperative clinical factors that relate to prolongation of hospital stay.

Methods: We studied 370 patients who underwent LC for gallbladder disease between 2008 and 2012.

A case of retroperitoneal liposarcoma after delivery with expression of estrogen receptor: Report of a case.

Introduction: Liposarcoma is one of the most common soft tissue sarcomas; however, early diagnosis is rare as the tumor remains difficult and unpalpable for a prolonged period of time.

Presentation Of Case: Here we report the first case of retroperitoneal liposarcoma associated with pregnancy and expression of estrogen receptor. A 34-year-old woman experienced persistent abdominal distension after her first delivery.

Immunodeficiency overview.

Primary immunodeficiencies are challenging in primary care settings, where clinicians often encounter patients with a history of recurrent infection. With advances in diagnostics and therapeutics, these disorders have been better understood and more successfully treated, yet their prognosis depends on early recognition of the disorder and initiation of the appropriate management. Because the primary care physician is most often the first physician encountered by a patient with immunodeficiency, primary care practitioners should be familiar with these rare but important disorders.

[A case of unresectable gastric cancer complicated by serious pyloric stenosis in which S-1 administration after gastrojejunostomy proved effective].

We report a patient with unresectable gastric cancer who was effectively treated with S-1 after gastrojejunostomy. A 64-year-old man was referred to our hospital for anorexia and epigastric palpable mass. Upper gastrointestinal endoscopy revealed an ulcerous tumor in the antrum of the stomach, and gastric roentgenography showed pyloric stenosis.

Surgical strategy for advanced gastric cancer with a concomitant thoracoabdominal aortic aneurysm requiring arterial reconstruction of the visceral branches.

A 70-year-old man who presented with hematemesis was found to have advanced gastric cancer concomitant with a thoracoabdominal aortic aneurysm (TAAA), which involved all branches of the visceral arteries. The patient underwent the following staged operations: first, radical resection of the advanced gastric cancer with simultaneous reconstruction of the visceral branches, followed 1 month later by endovascular aortic replacement of the TAAA. He recovered uneventfully and was discharged without any paralytic complications or sign of graft infection.

Pulmonary infection with Mycobacterium neoaurum identified by 16S ribosomal DNA sequence.

Mycobacterium neoaurum infection has rarely been found in humans, and only a limited number of cases have been reported. We describe the first case of pulmonary infection with M. neoaurum.

Possible role of human herpesvirus 8 in the lymphoproliferative disorders in common variable immunodeficiency.

Patients who have common variable immunodeficiency (CVID) and granulomatous/lymphocytic interstitial lung disease (GLILD) are at high risk for early mortality and B cell lymphomas. Infection with human herpes virus type 8 (HHV8), a B cell lymphotrophic virus, is linked to lymphoproliferative disorders in people who have secondary immunodeficiencies. Therefore, we determined the prevalence of HHV8 infection in CVID patients with GLILD.

Granulomatous disease in common variable immunodeficiency.

Common variable immunodeficiency (CVID) is a primary immunodeficiency of unknown etiology characterized by low levels of immunoglobulin (Ig)G, failure to make specific antibodies in response to infection or immunization, and variable T-cell abnormalities. Multisystemic granulomatous disease is a well-documented complication of CVID, and its presence is associated with significant morbidity and early mortality. Although the lung is the most common organ system affected, granulomas are also found frequently in other organs, including skin, liver, spleen, and the gastrointestinal tract.

Esophagobronchial fistula in a patient with Behçet's disease: report of a case.

Esophageal involvement in Behçet's disease is generally considered to be very uncommon. So far, six cases of esophageal ulcers associated with perforation, penetration, or fistula in Behçet's disease have been described in the English literature. This report describes esophagobronchial fistula in a patient with intestinal Behçet's disease.

Epigenetic inactivation of class II transactivator (CIITA) is associated with the absence of interferon-gamma-induced HLA-DR expression in colorectal and gastric cancer cells.

Tightly regulated at the level of transcription, expression of MHC class II molecules varies significantly among gastrointestinal cancers. High levels of MHC class II expression are often associated with a better prognosis, which is indicative of the involvement of CD4+ lymphocytes in tumor suppression, but the molecular mechanism by which MHC class II expression is regulated remains unclear. In the present study, we investigated the expression of one inducible MHC class II molecule, HLA-DR, and its coactivators in a panel of colorectal and gastric cancer cell lines.
