    The presence of circulating anti-nuclear antibodies (ANAs) is a hallmark of immune dysregulation in patients with systemic sclerosis (SSc). Currently, a variety of SSc-specific ANAs, including anticentromere, anti-topoisomerase I, and anti-RNA polymerase III antibodies, have been well characterized, and their commercial kits are available worldwide. Since these autoantibodies are specifically detected in SSc patients and are associated with unique sets of disease manifestations, they are widely used in routine clinical practice for diagnosis, clinical subgrouping, and prediction of future organ involvements and prognosis. In addition, SSc-specific ANAs are also useful in predicting future development of SSc in patients with Raynaud's phenomenon without any scleroderma skin changes, because their production often precedes onset of SSc symptoms. Application of circulating SSc-specific ANA measurement to clinical practice has greatly improved patient care, but utility of the autoantibody testing could be maximized by combining other clinical information, such as degree and extent of skin thickness and disease duration.

    Haptoglobin exerts renal protective function by scavenging free hemoglobin from the urine and blood stream in patients with hemolytic disorders. Recent studies elucidate the relationships between haptoglobin and inflammation. In addition, coagulopathy is often induced by systemic inflammation characterized by the presence of vascular endothelial damage. We hypothesize that haptoglobin might have an anti-inflammatory effect and affect hypercoagulability using rat burn model. Thirty anesthetized rats of six-weeks of age received over 30% full-thickness scald burn on the dorsal skin surface. All rats were injected with either haptoglobin (Hpt) or normal saline (NS) intraperitoneally. The rats were divided into three groups: 1) control group (NS 20 mL/kg); 2) low concentration of Hpt group, L-Hpt, (Hpt 4 mL (80 U) /kg+NS 16 mL/kg); and 3) high concentration of Hpt group, H-Hpt, (Hpt 20 mL (400 U) /kg). While under anesthesia, all rats were euthanized by exsanguination at 6 hours (N=5) and 24 hours (N=5). Inflammatory and anti-inflammatory cytokines were measured and whole-blood viscoelastic tests were performed by thromboelastometry (ROTEM). Haptoglobin significantly reduced free hemoglobin 24 hours after the injury. Improvement of hematuria was confirmed in the H-Hpt group. There were no differences in thrombin-antithrombin complex and plasmin-α2 plasmin inhibitor complex. The haptoglobin tended to decrease interferon-gamma (IFN-γ) in H-Hpt group. ROTEM findings of the L-Hpt group showed significantly higher clot firmness and shorter time to maximum clot formation velocity than the control group. Haptoglobin reduced INF-γ, and accelerated speed of clot formation in acute phase of severe burn.

    Introduction: Transurethral resection of the prostate (TURP) is the gold standard for surgical treatment of benign prostatic hyperplasia (BPH), but it has complications such as bleeding and transurethral resection syndrome. The treatment results of TURP performed by non-Japanese board-certified urologists were examined, and the results were analyzed according to the resection volume to determine how much resection volume was suitable for non-Japanese board-certified urologists. Materials and Methods: A total of 72 cases that underwent TURP for BPH at our hospital were examined. The patients were divided into three groups by resection volume (<20 g, 20-30 g, >30 g). The operators were five non-Japanese board-certified urologists. Various clinical factors were examined among the three groups before and after TURP. Results: The average operation time and resection volume were significantly different among the groups. There were more transfused cases with greater resection volume. The changes from before to after TURP in the International Prostate Symptom Score, total prostate volume, and maximum flow rate were significantly different among the three groups, but the rates of these changes were not. Conclusions: In this study, TURP performed by non-Japanese board-certified urologists was relatively safe and achieved sufficient efficacy. Cases with resection volume less than 20 g appear the most appropriate for non-Japanese board-certified urologists.

    We report a case of syringocystadenoma papilliferum (SCAP) combined with tubular papillary adenoma (TPA) arising on the chest of a 45-year-old Japanese woman. Histopathological examination revealed the characteristic findings of SCAP in the superficial part of the lesion and those of TPA in the deeper part. We reviewed the English literature about this combination. SCAP and TPA have the same cellular components, but show differences of the general structure. The combination of these two neoplasms is more frequent than expected by most dermatopathologists or pathologists. This combination is frequently seen in patients with nevus sebaceus (NS), but it is also found in patients without NS.

    Background: Primary volvulus of the small intestine associated with chylous ascites is very rare, with only four reported cases. In this paper, we report a new case of primary volvulus associated with chylous ascites. Case Presentation: The patient was a 70-year-old man. After experiencing bloating and abdominal pain for several hours, he called an ambulance and underwent an emergency examination at our hospital. Abdominal distension, pressure pain, and rebound tenderness were observed throughout his entire abdomen. The patient had a history of hypertension for which he was receiving oral treatment. Abdominal contrast-enhanced computed tomography (CT) revealed an edematous change in the intestinal membrane and volvulus of the small intestine. As findings suggestive of ischemia were observed in part of the intestines, emergency surgery was performed on the day of admission. Open surgery revealed approximately 500 mL of chylous ascites in the abdominal cavity. The small intestine had twisted 180° in a counter-clockwise direction at the root of the superior mesenteric artery, and the mesentery appeared milky white with edematous changes extending 75 to 240 cm from the ligament of Treitz. There was no evidence of intestinal necrosis; therefore intestinal resection was not performed. The volvulus of the small intestine was corrected. Moreover, because there was no other underlying disease observed, surgery was completed. The ascites collected during surgery revealed high levels of triglycerides at 332 mg/dL, and chylous ascites was diagnosed. An abdominal CT performed on the third day after surgery showed an improvement in intestinal edema, and primary volvulus of the small intestine associated with chylous ascites was diagnosed. Postoperative progress was good, and the patient was discharged on hospital day 10.

    Herein, we describe our experience in treating a case of primary pulmonary mucosa-associated lymphoid tissue lymphoma detected as a nodular opacity. A 79-year-old man was referred to our hospital. Computed tomography showed a nodular opacity measuring 20 mm in diameter with regular margins in segment 5 of the right middle lobe of the lung. Although the bronchoscopic brush cytology result was class III, the patient was tentatively diagnosed with suspected mucosa-associated lymphoid tissue lymphoma. A thoracoscopic right middle lobectomy was performed. The pathological findings showed nodular proliferation of small to medium-sized, mature-appearing atypical lymphoid cells, lymphoepithelial lesions, and vague follicles suggesting follicular colonization in some areas. The patient was diagnosed with low-grade small B-cell lymphoma and mucosa-associated lymphoid tissue lymphoma. He has remained well to date, 23 months after surgery, without evidence of recurrence.

    Vaginal cuff dehiscence is a rare but serious complication that can develop after hysterectomy. Emergent surgical intervention is required for vaginal cuff dehiscence due to the potential subsequent vaginal evisceration, which may lead to necrosis of the small bowel. A 62-year-old nulliparous woman with a 30-year history of smoking, diabetes mellitus, and rheumatoid arthritis (treated with oral steroids) presented with a vaginal cuff dehiscence. Thirty-eight days before the admission, she had undergone a radical operation including total abdominal hysterectomy for uterine corpus cancer at another hospital. We performed emergent laparoscopic surgery to reduce the prolapsed small bowel into the abdominal cavity and repaired the vaginal cuff with a two-layer continuous closure using absorbable barbed sutures. The patient experienced no postoperative complications, and no recurrence of the vaginal cuff dehiscence occurred. Vaginal cuff dehiscence and evisceration can be surgically managed using an abdominal, vaginal, or laparoscopic approach, and the choice of method should be based on patient characteristics and the surgeon's skills. Laparoscopic vaginal cuff repair with a two-layer continuous closure using absorbable barbed sutures is a minimally invasive technique that is safe and effective for medically stable patients with no small bowel injury or vascular compromise and no pelvic abscess.

    A lipoma is a slow-growing, benign tumor and is usually asymptomatic; hence, surgical intervention can often be avoided in patients with these tumors in the cervical and cranial area. Lipomas arise most commonly in the subcutaneous fat, but occasionally in muscle tissue. Intramuscular lipomas in the cervico-cranial area have rarely been reported. We describe here a patient with a large intramuscular lipoma in the deep cervical tissue. The patient experienced troublesome pain in the neck and occipital area, and surgical treatment was therefore suggested. Particularly in the cervical area, intramuscular lipomas sometimes invade the surrounding muscles and tissue layers and develop into an irregular mass, despite being benign. In addition, the cervical area has one of the most complex muscle structures. Nevertheless, surgical management of intramuscular lipoma in the cervical and cranial area is sometimes indicated, for example, in patients with clinical symptoms or masses with a tendency to grow large.

    Although presacral developmental cysts, including epidermoid cysts, are relatively rare diseases, an intrapelvic mass found for the first time in early pregnancy should be followed-up with the possibility of presacral developmental cysts in mind to be alert to the signs of local infection and malignancy. We treated a pregnant patient with presacral cystic disease. During pregnancy, percutaneous fenestration was performed because the cyst caused severe compression symptoms and complicated bacterial infection. Laparoscopic total cyst excision was performed after cesarean section. There is no suggested criterion to make a decision for the delivery mode. The mass should be removed completely to reduce the risk of recurrence and malignant progression.
