Background: Systemic inflammatory response syndrome (SIRS) is a clinical condition representing the culmination of the activation of a complex network of acute endogenous mediators.
Materials and Methods: We investigated both the relationship between the results of SIRS assessments in 212 trauma patients at the time of hospital arrival and measures of trauma severity determined using the Injury Severity Score (ISS) and the Revised Trauma Score (RTS). We then considered the possibility of whether this assessment could be used to predict the development of organ dysfunction as a complication in trauma patients after admission. The serum neutrophil elastase (SNE) level was also measured in 47 cases.
Results: The cases with SIRS had a significantly higher ISS and a lower RTS. Organ dysfunction occurred in 22 cases, and a significant correlation was noted between the development of organ dysfunction and the presence of SIRS (86.4%; 19 cases/22 cases, p=0.0007) at the time of arrival. The SNE level was significantly higher among the patients who fulfilled the four SIRS criteria than among the other patients (p=0.0301).
Conclusion: We concluded that the greater the SIRS score at the time of hospital arrival, the greater the anatomical and physiological severity of the trauma patient's condition.

Arterial stiffening may contribute to secondary myocardial dysfunction. The aim of this study was to assess the stiffness of the thoracic descending aorta (TDA) by performing strain-rate measurements with transesophageal echocardiography (TEE) and to examine the relation of the findings to left ventricular (LV) function. Eight patients (group I) without risk factors for arteriosclerosis and 52 patients (group II) with a high risk of arteriosclerosis underwent transthoracic echocardiography (TTE) and TEE simultaneously. The values of distensibility of the TDA (-SR) in groups I and II were -11.7 ± 2.4 and -4.6 ± 2.5, respectively (p<0.001), and the values of the recoil of the TDA (+SR) were 20.5 ± 8.2 and 6.8 ± 5.0, respectively (p<0.001). The LV ejection fraction showed no relation with -SR or +SR, but LV diastolic function (e' and E/e') was correlated with +SR (p=0.002 and p=0.046, respectively). Strain-rate measurements obtained with TEE were useful for evaluating impairment of the elastic properties of the TDA and the pathophysiologic mechanisms underlying the arterial-ventricular relationship.

Objective: Deep vein thrombosis (DVT) is a major risk factor for pulmonary thromboembolism (PTE). We carefully selected patients for surgical thrombectomy to treat acute-phase thrombosis and obtained favorable results.
Methods: Over the past 5 years, we have performed surgical thrombectomy via a minimum femoral skin incision in 11 patients. Surgery was considered for patients with persistent phlegmasia cerulea dolens, despite thrombolytic therapy. All of our patients underwent surgery within 14 days of the onset of symptoms. During the operation, the patients were kept in the supine anti-Trendelenburg position to prevent PTE, and general anesthesia was maintained with positive-pressure mechanical ventilation. Blood flow to the inferior vena cava was occluded with a blocking catheter, and thrombectomy was performed with a thrombectomy catheter inserted parallel to the blocking catheter. A cell separator device was used effectively for autologous blood transfusion. To prevent reocclusion and promote collateral perfusion, we constructed an arteriovenous fistula for an iliac venous spur.
Results: There were no major postoperative complications, such as PTE or peritoneal bleeding, and no cases of postthrombotic syndrome after an average 38.4 months of follow-up.
Conclusion: This surgical technique for venous thrombectomy is minimally invasive and safe for Japanese patients; surgical thrombectomy should be considered a treatment option for DVT in Japan.

Background: Although hypertension is a well-documented risk factor for cardiovascular diseases, including myocardial infarction and stroke, in adults, only recently has knowledge about childhood hypertension increased significantly.
Aim: To determine the incidence of asymptomatic hypertension in school-age children.
Subjects and Methods: Children in primary school were chosen with a randomized sampling method. During measurement of blood pressure, a calm, comfortable setting was provided. Blood pressure measurements were performed by only 1 researcher. For accurate measurement of blood pressure, recommended standards were followed.
Results: A total of 1,963 children were included in the study. The incidence of systolic hypertension and diastolic hypertension were 7% and 2%, respectively. Obesity was present in 10.5% girls with hypertension and 13.9% of boys with hypertension.
Conclusion: Our findings indicate that hypertension is an important health problem in children, and its prevalence is quite high. Blood pressure measurements must be a part of routine clinical examinations. Further studies should be performed in high-risk populations to prevent hypertension and to establish methods of early diagnosis and treatment in children.

Few cases of clostridial gas gangrene associated with uterine malignancy have been reported. We report on a 46-year-old woman with clostridial sepsis. On the day of admission due to severe abdominal pain, peritonitis was diagnosed, and computed tomography showed free air in the abdomen. At emergency laparotomy, perforation of the necrotic uterine wall was observed. During hysterectomy, septic shock developed, and life-saving therapy was performed in the intensive care unit after surgery. Pathological examination of the necrotic uterine wall showed grade III endometrial adenocarcinoma of the uterine endometrium (International Federation of Gynecology and Obstetrics stage IIIa) with gas gangrene due to Clostridium perfringens. This report aims to alert gynecologists to the possibility that clostridial gas gangrene of the uterus can occur in patients with peritonitis and intra-abdominal free air. Early recognition and aggressive therapy can save patients' lives.

We report on a patient with obstructive jaundice caused by recurrence of gastric carcinoma in the wall of an extrahepatic bile duct more than 5 years after gastrectomy who was treated with pancreaticoduodenectomy. Histopathologic examination of the surgically resected specimen revealed a poorly differentiated adenocarcinoma with focal signet ring cells in the wall of the common bile duct which was histologically similar to the primary gastric carcinoma. To confirm the diagnosis, immunohistochemical staining was performed with antibodies against cytokeratins (CK7, CK20) and mucin peptide core antigens (MUC5AC, MUC6, MUC2). Based on the expression patterns of this monoclonal antibody panel, the final diagnosis of the common bile duct tumor was an isolated local recurrence of the gastric carcinoma. The patient has survived for more than 26 months after pancreaticoduodenectomy without recurrence.

We describe a 43-year-old woman who underwent laparoscopic distal pancreatectomy preserving the spleen and splenic vessels for the treatment of insulinoma in the pancreatic body. The patient experienced cold sweats on fasting, received diagnosis of insulinoma, and was referred to our hospital for laparoscopic surgery. Blood biochemistry studies showed low fasting blood glucose of 42 mg/dL, serial immunoreactive insulin of 15.2 μU/mL, and a Fajans index (immunoreactive insulin/blood glucose) of 0.36 (normal <0.30). Contrast-enhanced early-phase computed tomography of the abdomen showed a circular, intensely stained, 1.6-cm-diameter tumor in the pancreatic body close to the main pancreatic duct. A solitary insulinoma of the pancreatic body was diagnosed on the basis of the result of hematologic studies, and diagnostic imaging results. Because of the location of the tumor, we elected to perform distal pancreatectomy preserving the spleen and splenic vessels, rather than enucleation. Insulin and blood glucose levels were monitored during surgery. Before removal of the tumor, insulin levels remained consistently high, never decreasing to less than 10 μU/mL. After surgery, insulin levels decreased rapidly, to less than 5 μU/mL within 30 minutes and subsequently remained at the new low level, leading us to conclude that the entire tumor had been removed. There were no postoperative complications, and the patient was discharged from the hospital on day 7.
There was no major intraoperative bleeding other than at the resected surface. The patient was ambulatory soon after the procedure, and had a brief hospital stay therefore, the surgery was judged to have been highly useful in this case.

We describe the spontaneous rupture of a simple hepatic cyst associated with a benign course. A 64-year-old woman was admitted for right upper quadrant pain. The patient denied a history of abdominal trauma. Abdominal computed tomography (CT) showed a huge solitary hepatic cyst (diameter, 10 cm) in the right lobe. Part of the cyst surface was irregular, and the interior was heterogeneous on ultrasonography. Fluid retention was detected under the liver capsule. Spontaneous rupture of a nonparasitic hepatic cyst was suspected. The patient was admitted to our hospital for further evaluation and treatment. Examination of the abdomen revealed right upper quadrant pain but no signs or symptoms of peritonitis. One week after admission, CT revealed that the volume of fluid retained under the liver capsule had decreased. Percutaneous puncture was performed with a needle and an 8-French pigtail catheter under ultrasonographic guidance. Serous, brown fluid was aspirated. After percutaneous aspiration, the patient's symptoms resolved. Minocycline hydrochloride was given daily by intravenous injection for 7 days. The catheter was then removed. There has been no evidence of recurrence after 1 year.
