Giant splenic artery aneurysm rupture into the stomach that was successfully managed with emergency distal pancreatectomy.

Background: Splenic artery aneurysms usually rupture into the free peritoneal space and rarely into the gastrointestinal tract. We report the case of a patient with a giant splenic artery aneurysm that ruptured in to the stomach with hemorrhagic shock and was successfully treated with emergency surgery.

Case Presentation: A 59-year-old man presented to the emergency department with chest pain and syncope.

Serrated polyposis syndrome with multiple inverted lesions in the colon: Case report and elucidation of morphogenetic mechanism.

A 70-year-old man underwent surveillance colonoscopy following surgery for occlusive sigmoid colon cancer. The procedure revealed nine sessile serrated lesions (SSLs), including three inverted lesions. Endoscopic and surgical resections were performed.

[Two Cases of Stage Ⅳ Occult Breast Cancer].

The first case is a 62-year-old female who complained of painful left axillary lymph node swelling. Six months later, a CT scan revealed multiple lung nodules. Biopsies of the axillary lymph node and lung showed metastatic carcinoma from breast cancer.

[A Case of Long-Term Survival after Para-Aortic Lymph Node Recurrence Following the Curative Resection of Gastric Cancer Treated Using Multimodality Therapy Including Salvage Surgery].

This case was observed in a man in his 70s. Although symptomatic treatment was performed for epigastralgia, endoscopic examination revealed a type 3 tumor on the fornix of the stomach to the lesser curvature of the body just above the esophagogastric junction, and the patient was diagnosed with moderately differentiated tubular adenocarcinoma(cT4bN3aM0, cStage ⅣA). As esophageal and diaphragmatic invasion was suspected based on CT findings, S-1 plus CDDP was started as preoperative chemotherapy.

[A Case of Breast Metastasis of Gastric Cancer after an Eight Year Latency Period].

A 66-year-old woman underwent distal gastrectomy because of gastric cancer(stage ⅠB)and received no adjuvant chemotherapy. Eight years after the operation, computed tomography showed a small nodule in the right breast. Mammography did not reveal any abnormalities.

[A Case of Primary Spinddle Cell Carcinoma of the Breast].

A 76-year-old female underwent breast-conserving surgery of the right breast and sentinel lymph node biopsy for primary breast cancer. Three years later, mammography and ultrasonography showed a small nodule in the right breast. There was nothing abnormal in the left breast.

Diminished abductor muscular strength in patients with valgus-impacted femoral neck fractures treated by internal fixation: Clinical study and biomechanical considerations.

Background: Valgus-impacted femoral neck fractures treated with internal fixation occasionally result in unsatisfactory postoperative locomotive function, partially due to muscle shortening and a decrease in the moment arm. This study quantifies the degree of diminished abduction strength both clinically and biomechanically.

Methods: Fifteen patients were enrolled in this study.

Comparison of Post-Operative Muscular Strength Between Gamma Nailing and Hemiarthroplasty System in Femoral Intertrochanteric Fractures.

Background: The current study focuses on the comparison of postoperative muscular strength around the hip joint of patients with femoral intertrochanteric fractures treated either by cephalo-medullary (CM) nailing or a new bipolar hip prosthesis (BHP), an especially attached device to secure displaced greater trochanteric fragment.

Methods: Twenty patients treated with CM nailing were age- and sex- matched with a control group of 20 patients treated with BHP. Maximum isometric forces at the bilateral hip joint were measured during the follow up period.

Subtilisin-like proprotein convertase PACE4 is required for skeletal muscle differentiation.

Most growth factors stimulate myoblast proliferation and prevent differentiation, whereas insulin-like growth factors (IGFs) promote myoblast differentiation through the phosphatidylinositol 3-kinase (PI3K) pathway. Subtilisin-like proprotein convertases (SPCs) are involved in cell growth and differentiation via activation of pro-growth factors. However, the role of SPCs in myogenesis remains poorly understood.
