Abstract Pneumocystis pneumonia (PCP) due to Pneumocystis jirovecii infection is the leading cause of fatal opportunistic infections in immunocompromised patients. We will determine whether a daily sulfamethoxazole-trimethoprim (SMX/TMP) dose of 200/40 mg was non-inferior to 400/80 mg for PCP prevention in patients with systemic rheumatic disease under immunosuppressive therapy. This is a randomized, open-label, multicenter controlled trial. The primary outcome is the rate of PCP prevention at 52 weeks. The secondary outcome is the discontinuation rate of SMX/TMP. The trial will evaluate the optimal dose of SMX/TMP for PCP prevention in patients with systemic rheumatic disease under immunosuppressive therapy.

Abstract Endoscopic submucosal dissection (ESD) is reportedly one of the standard treatment strategies for large superficial colorectal neoplasms in Japan because of its high en bloc resection rate. A few technical issues regarding ESD should be considered, one of which is the selection of the Endo-cut I mode versus the Swift-coagulation mode as the electrosurgical unit mode setting during submucosal dissection. We seek to determine which of these two modes is more suitable for submucosal dissections of colorectal tumors with regard to procedure time and safety.

Abstract Anterior cervical plate fixation is a common surgical treatment for cervical spine trauma, disc herniation, or cervical spondylosis. Esophageal perforation following anterior cervical plate fixation is a rare but serious complication. Management of esophageal perforation is controversial; however, we suggest treating most cases surgically because this condition is slow to heal and often fatal. We managed 2 cases of esophageal perforation following anterior cervical plate fixation by flap reconstruction with the pectoralis major muscle in one case and a jejunal free flap in the other. Here, we report our experience and review the surgical indications.

Abstract Preoperative oral care is helpful to prevent postoperative complications in patients who are undergoing esophagectomy. Here, we report the case of an 81-year-old Japanese man with an upper limb disability caused by post-polio syndrome who was receiving neoadjuvant chemotherapy for esophageal cancer. He had poor oral health status and developed oral complications as a side effect of chemotherapy. He could not brush his teeth by himself. However, infection control by oral care provided by an interprofessional collaboration successfully improved his oral hygiene, and his follow-up involved no severe complications. Interprofessional collaboration is useful especially for patients with upper limb disability.

Abstract We report a case of congenital multiple ocular motor nerve palsy combined with splitting of the lateral rectus muscle (LR). A 59-year-old Japanese female was investigated for worsening esotropia after corrective surgery. She presented with left hypertropia (35Δ) and esotropia (45-50Δ). Orbital magnetic resonance imaging (MRI) showed reduced belly sizes in the superior rectus, inferior rectus, and superior oblique muscles and splitting of the LR, extending from the origin to the belly, in the left eye. Splitting of the LR belly was detected on MRI in a case of congenital multiple ocular motor nerve palsy.

Abstract Patients with multi-system (MS)-type langerhans cell histiocytosis (LCH) show poor outcomes, especially congenital MS LCH cases were shown in high mortality rate. We experienced a congenital case of MS LCH with high risk organs, who needed intensive respiratory support after birth. Even though intensive chemotherapy was discontinued, this patient’s lung LCH lesions gradually became reduced and his respiratory condition recovered; therefore, we restarted and completed maintenance chemotherapy. The patient maintained complete remission for more than 4 years after the end of chemotherapy. Our case suggests that congenital MS LCH even with severe organ involvement can be treated successfully with chemotherapy.

Abstract  We investigated the relationship between body mass index (BMI) and postoperative outcomes in 450 gallbladder cancer patients in Japan. We collected patient information, including sex, age, underlying disease, BMI, stage, surgery method, postoperative time to discharge, and postoperative Medicare fees, from the Japanese administrative database associated with the Diagnosis Procedure Combination system. We classified patient BMIs as underweight (BMI<18.5 kg/m2), normal (BMI≥18.5 kg/m2 and <25 kg/m2) or overweight/obese (BMI≥25 kg/m2), then investigated the relationship between these categories and two postoperative outcomes: time to discharge and postoperative Medicare fees. The median postoperative time to discharge was 12 days in all patients, and 12 days in each of the three weight groups (p=0.62, n.s.). The median postoperative Medicare fees from surgery until discharge were (USD): all patients, $5,002; underweight, $5,875; normal weight, $4,797; and overweight/obese, $5,179 (p=0.146, n.s.). A multivariate analysis with adjustment for competing risk factors revealed that BMI was not associated with increased risk of longer postoperative time to discharge (normal weight: HR 1.17, p=0.29; overweight/obese: HR 1.17, p=0.37) or higher postoperative Medicare fees (OR 0.99, p=0.86, n.s.). Thus, high BMI was not found to be a factor for poor postoperative outcomes in Japanese patients with gallbladder cancer.

Abstract Post-orthotopic liver transplantation (OLT) hepatitis B recurrence is well-controlled with a nucleos(t)ide analogue and hepatitis B immunoglobulin (HBIG) combination, but the high cost and the potential risk of unknown infection associated with HBIG remain unresolved issues. Low-cost recombinant hepatitis B virus (HBV) vaccine administration is a potential solution to these problems. We retrospectively analyzed the rate and predictive factors of HBV vaccine success in 49 post-OLT patients: liver cirrhosis-type B (LC-B), n=28 patients; acute liver failure-type B (ALF-B), n=8; and non-HBV-related end-stage liver disease (non-B ESLD) who received a liver from anti-hepatitis B core antibody-positive donors, n=13. A positive anti-hepatitis B surface antibody response was achieved in 29% (8/28) of the LC-B group, 88% (7/8) of the ALF-B group, and 44% (4/9) of the adult non-B ESLD group. All four non-B ESLD infants showed vaccine success. The predictive factors for a good response in LC-B were young age, marital donor, and high donor age. ALF-B and non-B ESLD infants are thus good vaccination candidates. LC-B patients with marital donors are also good candidates, perhaps because the donated liver maintains an efficient immune memory to HBV, as the donors had already been infected in adulthood and showed adequate anti-HBV immune responses.

Abstract Cerebral vasospasm (CVS) is a major contributor to the high morbidity and mortality of aneurysmal subarachnoid hemorrhage (aSAH) patients. We measured histidine-rich glycoprotein (HRG), a new biomarker of aSAH, in cerebrospinal fluid (CSF) to investigate whether HRG might be an early predictor of CVS. A total of seven controls and 14 aSAH patients (8 males, 6 females aged 53.4±15.4 years) were enrolled, and serial CSF and serum samples were taken. We allocated these samples to three phases (T1-T3) and measured HRG, interleukin (IL)-6, fibrinopeptide A (FpA), and 8-hydroxy-2’-deoxyguanosine (8OHdG) in the CSF, and the HRG in serum. We also examined the release of HRG in rat blood incubated in artificial CSF. In contrast to the other biomarkers examined, the change in the CSF HRG concentration was significantly different between the nonspasm and spasm groups (p<0.01). The rat blood/CSF model revealed a time course similar to that of the human CSF samples in the non-spasm group. HRG thus appears to have the potential to become an early predictor of CVS. In addition, the interaction of HRG with IL-6, FpA, and 8OHdG may form the pathology of CVS.

Abstract We measured basal clitoral blood flow by Doppler sonography to determine whether tension-free vaginal mesh(TVM) affects the clitoral blood flow and sexual function in women with pelvic organ prolapse (POP). We performed a prospective study of 22 patients who underwent TVM for POP. Clitoral blood flow was measured by Doppler ultrasound. The resistance index (RI), pulsatility index (PI), peak systolic velocity (PSV), and end-diastolic velocity (EDV) of the clitoral arteries were measured preoperatively and at 1, 3, and 6 months postoperatively. Female sexual function was also investigated with the Female Sexual Function Index (FSFI). The mean PI and RI were increased at 1 month and significantly decreased at 6 months postoperatively (p<0.05). In contrast, the mean PSV and EDV decreased at 1 month postoperatively and increased at 6 months postoperatively. These four parameters recovered to baseline levels at 6 months following surgery. Total FSFI scores improved significantly from 10.2±7.9 at baseline to 18.2±8.9 at 6 months postoperatively. Color Doppler ultrasonography is potentially useful in measuring clitoral blood flow in patients treated with TVM for POP. Prospective long-term studies are needed to evaluate the utility of this modality as a diagnostic and prognostic tool for female sexual dysfunction.

Abstract We compared the reintubation rate in children who received high-flow nasal cannula (HFNC) therapy to the rate in children who received noninvasive ventilation (NIV) therapy for acute respiratory failure (ARF) after cardiac surgery. This was a retrospective analysis of 35 children who received HFNC therapy for ARF after cardiac surgery in 2014-2015 (the HFNC group). We selected 35 children who had received NIV therapy for ARF after cardiac surgery in 2009-2012 as a control group. The matching parameters were body weight and risk adjustment for congenital heart surgery category 1. The reintubation rate within 48 h in the HFNC group tended to be lower than that in the NIV group (3% vs. 17%, p=0.06). The reintubation rate within 28 days was significantly lower in the HFNC group compared to the NIV group (3% vs. 26%, p=0.04). The HFNC group’s ICU stays were significantly shorter than those of the NIV group: 10 (IQR: 7-17) days vs. 17 (11-32) days, p=0.009. HFNC therapy might be associated with a reduced reintubation rate in children with ARF after cardiac surgery.

Abstract We evaluated the analgesic effects of multimodal pain control in which intravenous acetaminophen (IV APAP) was added to the standard protocol for Japanese patients who had undergone a total hip arthroplasty (THA). We performed a retrospective cohort study of 180 patients aged 66.4±10.5 years (30% male) who had undergone a THA (Oct. 2014 to Feb. 2015) at our hospital. The control patients were administered the standard analgesic protocol: flurbiprofen axetil as a continuous intravenous infusion and oral celecoxib (NAPAP; n=109). The patients in the new analgesic protocol group received IV APAP in addition to the standard analgesic protocol (APAP; n=71). The primary outcome was the maximum value of postoperative pain the patients reported on a numerical rating scale (NRS) during the first 24 h post-surgery. A univariate analysis and multivariate analyses adjusted for age, sex, the stage of hip osteoarthritis, preoperative pain, and surgical time showed that the maximum postoperative pain NRS scores during the first 24 h after surgery was significantly lower when the APAP protocol was used. The addition of IV APAP to the current standard multimodal analgesia protocol for Japanese patients who have undergone a THA may decrease the patients’ postoperative pain.

Abstract Excessive protease activity is a characteristic abnormality that affects the epidermal barrier in patients with atopic dermatitis (AD). Kallikrein-related peptidases (KLKs) are excessively expressed in AD lesions, and it is suggested that the abnormal action of KLKs is involved in the skin barrier dysfunction in AD. In other words, overexpressed KLKs disrupt the normal barrier function, and due to that breakdown, external substances that can become antigens of AD easily invade the epidermis, resulting in dermatitis, coupled with the induction of Th2 cytokines. Further investigations are required to elucidate the role of KLKs in AD; this knowledge could contribute to the design of new therapeutic and prophylactic drugs for AD.
