Recent reports suggest that uncemented total hip replacement arthroplasty (THR) results in favorable short- to mid-term clinical results. In the present study, we assessed the mid-term clinical results of VerSys Hip System uncemented THR at our hospital. Materials and Methods: We studied patients who received THR using VerSys Hip System and who could be followed-up more than 3 years. Clinical records were used to retrospectively identify patient characteristics, which included age, gender, disease requiring THR, preoperative and postoperative pain score of the Japan Orthopaedic Association scoring system, range of motion in flexion and abduction, operating time, intraoperative complication, and additional operation or revision surgery. Additionally, we investigated the loosening and alignment of implants from X-ray films. Results: Ninety-one patients and 108 hip joints were investigated. Subjects were 11 males and 97 females (mean age, 64.6 years). Mean follow-up period was 6.9 years. Reasons for requiring THR were as follows: secondary osteoarthritis, 87 joints; idiopathic osteonecrosis of the femoral head, 16 joints; rapidly destructive coxarthrosis, 4 joints; and idiopathic ossification of the labrum, 1 joint. Mean operating time was 166 minutes. A total of 11 intraoperative fractures occurred, and wiring was performed in 3 of those cases. Adverse events pertaining to the surgery were limited; however, another adverse event was that 1 case resulted in intraoperative perforation of femoral cortex, for which a revision surgery was performed. There was no dislocation. Pain score using the Japan Orthopaedic Association scoring system and range of motion tests showed statistically significant improvement following THR. At the final follow-up, although no loosening of femoral implants was observed, the loosening of acetabular component was seen in 1 case. Varus insertion of femoral implant was recognized in 40 joints. Moreover, the average inclination angle of acetabular implants was 52.2 degrees. Conclusion: These data suggest that patients receiving VerSys Hip System uncemented THR demonstrate favorable results pertaining pain score and range of motion. However, high rate of intraoperative fracture and malalignment of implants, which may be at a risk of dislocation and/or polyethylene wear in future, suggests that this implant technique requires improvement.

We performed a cross-sectional survey to investigate actual clinical practice concerning blood-pressure control among patients with hypertension in Kanagawa. The guidelines of the Japanese Society of Hypertension (JSH) for the management of patients with hypertension were revised in 2014. From October 1 to November 30, 2014, questionnaires on the care of patients with hypertension were sent via post to members of the Kanagawa Physicians Association in Kanagawa Prefecture, Japan. -Data on 1,105 patients (mean age: 68.4±12.3 years, 537 men and 568 women) were obtained. The overall mean systolic blood pressure (BP) of these patients was 128.7±12.1 mmHg for home monitoring and 132.9±12.6 mmHg for office monitoring; diastolic BP was 75.7±9.7 for home monitoring and 77.0±9.7 mmHg for office monitoring. According to the JSH 2014 guidelines, the target BP was achieved by 68.1% of all subjects; 89.2% of late-phase elderly patients (75 years or older); 69.1% of young, middle-aged, and early-phase elderly patients (younger than 75 years except in patients with diabetes mellitus [DM] or chronic kidney disease [CKD] with proteinuria); 9.3% of patients with DM except late-phase elderly patients; and 11.9% of CKD patients with proteinuria except DM. Cross-sectional analysis showed that the factors significantly associated with an increased likelihood of achieving the target BP were as follows: 1) good medication compliance even for a small number of antihypertensive agents at small amount of doses in patients 75 years and older; 2) good medication compliance in patients in younger than 75 years; 3) an older age, a larger proportion in the female-to-male ratio and a lower body mass index in patients with DM except late-phase elderly patients; and 4) usage of a large number of antihypertensive agents in CKD patients with proteinuria. Further follow-up surveys are necessary to investigate changes in clinical practice following the introduction of the revised guidelines.

In the present report, we describe a case of a patient with an asymptomatic aneurysm in the arc of Bühler (AOB), which was successfully treated by transcatheter arterial embolization. The patient presented with severe stenosis of the celiac trunk, which was suspected to be due to median arcuate ligament syndrome. Arteriography of the superior mesenteric artery indicated a rapid stream in an aneurysm in the AOB. Hence, embolization was carefully performed using detachable coils and microcoils. An arteriography performed after embolization did not show any aneurysm, and the hepatic artery and splenic artery could be detected via the pancreatic arcade, originating from the superior mesenteric artery. The AOB is a persistent embryonic ventral anastomosis present between the superior mesenteric artery and the celiac artery. This anastomotic artery is independent of the gastroduodenal artery and the dorsal pancreatic artery, and is extremely rare, with an incidence of <4%. Aneurysms of the AOB are even more uncommon, and such cases have been reported in association with stenosis or occlusion of the celiac trunk. Open surgical aneurysmectomy, with or without reconstruction, is the conventional treatment for such aneurysms. However, rapid advances in interventional radiology have enabled the safe and effective treatment of visceral aneurysms via transcatheter arterial embolization. Based on the current findings, we believe that transcatheter arterial embolization is a minimally invasive and valuable method that may serve as an initial treatment option for aneurysms of the AOB.

An 81-year-old man was admitted with upper abdominal pain and weight loss. Esophagogastroduodenoscopy revealed a large tumor located from the gastric angle to the body. Histological analysis of a biopsy revealed a moderately differentiated adenocarcinoma. Computed tomography revealed metastases in the liver and lung and the patient was subsequently diagnosed with metastatic advanced gastric cancer. He was treated with chemotherapy using S-1 (80 mg/m²) and cisplatin (CDDP) (60 mg/m²). Twenty-two months after chemotherapy, the gastric tumor, and the nodules in the liver and lung, had disappeared. We subsequently diagnosed a clinical complete response. The patient was treated with further S-1 monotherapy for 7 months after complete response assessment. He has lived for more than 7 years since the initial diagnosis without recurrence. Chemotherapy using S-1 and CDDP may be a potent strategy for improving survival in elderly patients with advanced gastric cancer.

On the basis of computed tomography (CT) examination, a prosthetic graft infection of very late onset was suspected in a 72-year-old man who had undergone replacement of an bifurcated prosthetic graft 6 years earlier because of an abdominal aortic aneurysm and bilateral common iliac artery aneurysms. Emergency CT-guided needle aspiration was performed, and analysis of directly aspirated fluid confirmed the rapid diagnosis. Instead of conventional emergency surgery, CT-guided catheter drainage was the initial treatment and led to the gradual improvement of symptoms and laboratory data. Elective staged surgery was performed later to examine the cavity around the prosthetic graft. The cavity was then filled with in-situ omentum. Thus, CT-guided catheter drainage as the initial treatment and following omentopexy as the staged surgery avoided the need for highly invasive conventional surgery.

Portal vein thrombosis (PVT) is a rare complication of liver transplantation which can lead to graft failure and patient death. Treatment can be difficult, especially in cases of PVT from the intrahepatic portal vein to the proximal jejunal veins. A 55-year-old woman had undergone living-donor liver transplantation with splenectomy for end-stage liver cirrhosis due to hepatitis C with hepatocellular carcinoma. Ten months after transplantation, massive ascites and slight abdominal pain developed, and computed tomography revealed a PVT between the intrahepatic portal vein and the superior mesenteric vein. Repeated interventional radiology procedures were used in combination with thrombolysis, thrombectomy, and metallic stent replacement to obtain favorable portal flow to the graft. Five years after being treated, the patient is well, with favorable portal flow having been confirmed. In conclusion, repeated and assiduous interventional radiological treatment combined with thrombolytic therapy, thrombectomy, and metallic stent replacement could be important for severe PVT.

Pott's puffy tumor is a subperiosteal abscess of the frontal bone with osteomyelitis which has become rare because of the widespread use of antibiotics. Here, we report a case of Pott's puffy tumor in a 46-year-old man who visited the department of dermatology with painful swelling of the forehead. Despite open drainage and oral antibiotic therapy, the symptoms recurred twice in the following month. Computed tomography revealed a fistula of frontal bone. The eventual diagnosis was Pott's puffy tumor. The patient underwent endoscopic surgery at the department of otorhinolaryngology and achieved a complete recovery.
