Background/Aims: Inflammatory bowel disease (IBD) is a chronic inflammation of the gastrointestinal tract. Some patients with this condition have been reported to present with immunoglobulin A nephropathy (IgAN), a renal complication that can cause end-stage renal failure, but the frequency of this comorbidity has not been described. Thus, the aim of this study was to investigate the frequency of IgAN in patients with IBD. Methods: This study included 620 patients with IBD (338 with ulcerative colitis [UC] and 282 with Crohn’s disease [CD]) from the Hiroshima University Hospital outpatient department. IgAN cases were identified from medical interviews, blood examinations (serum immunoglobulin A), and urinalyses (occult blood, proteinuria). Definitive IgAN cases were diagnosed by renal biopsies, while those detected through the clinical course and test results, but not clinically recommended for renal biopsy, were defined as suspected IgAN. Results: We analyzed 427 cases meeting the inclusion criteria (220 with UC and 207 with CD). The incidence of IgAN across all patients with IBD was 3.0%. The frequency of IgAN was significantly higher in patients with CD (11/207, 5.3%) than in those with UC (2/220, 0.9%) (P< 0.01). Moreover, a significant correlation was found between CD patients with ileostomy or colostomy and a diagnosis of IgAN. Conclusions Patients with IBD present a high incidence of IgAN, especially those with CD who have undergone ileostomy or colostomy.

A 70-year-old man with continuous diarrhea for over 1 month consulted a primary care doctor. He was treated with oral antibiotics and probiotics but his condition worsened. He developed generalized edema and was referred to our hospital. Abdominal ultrasound and computed tomography (CT) scan findings were suggestive of colon cancer with accompanying liver metastasis. Total colonoscopy and endoscopy for pathological diagnosis led to a diagnosis of cancer of the sigmoid colon accompanied with liver metastasis or liver abscess. We planned to perform sigmoidectomy with simultaneous resection of the liver lesion. However, we considered that he was not particularly fit to undergo two concurrent surgeries. Therefore, based on his physical condition, we planned to first do a sigmoidectomy. Before surgery, the fever persisted and a repeat CT scan showed deterioration of the liver lesion. We diagnosed the liver lesion as abscess and performed percutaneous transhepatic abscess drainage (PTAD). Three days after PTAD, we then performed sigmoidectomy. Subsequently, the liver abscess resolved and gradually disappeared. At 5 years after surgery, there has been no recurrence of the cancer or abscess.

A 17-year-old male was admitted to our hospital because of strong abdominal pain. His symptoms gradually worsened even after hospitalization, and contrast computed tomography (CT) revealed hemorrhage in the abdominal cavity. Interventional radiology (IVR) was performed to identify the bleeding site. No obvious source of bleeding was identifiable on IVR, so we opted to perform laparoscopic examination and hemostasis. The intraperitoneal finding was hematoma in the omentum, and omentectomy was performed for idiopathic omental hemorrhage because there was no history of trauma. The postoperative course was good and the patient was discharged after postoperative day 4. Performing laparoscopic surgery for omental hemorrhage facilitated minimally invasive treatment with a short hospital stay.

　　A 38-year-old woman was examined at our hospital because of cough, night sweats, and facial edema. Computed tomography of the chest revealed a large mass in the anterior mediastinum measuring 8.2×12.2 cm, with multiple nodules on both lungs. Bronchoscopy revealed multiple nodules parallel to the tracheal rings and obstruction of the anterior segmental bronchus of the right lung. The histopathological features were diagnostic of primary mediastinal large B-cell lymphoma. She underwent chemotherapy followed by radiation therapy to the mediastinal mass. After 8 months, she developed right cerebellar metastasis. Eventually, she received peripheral stem cell transplantation after 17 months.

Objective: Prescription check and inquiry is one of the most important operations of pharmacists to provide optimal drug therapy to the patient.  Although a number of studies related to inquiries of prescriptions have already been reported, there is little report about requests for doctor and hospital based on the examples.  Therefore, this study aimed to clarify the current problems revealed by inquiries about prescriptions by not only analyzing these inquiries but also investigating requests for doctors and hospitals.
Methods: We investigated 6,255 inquiries about prescriptions and requests for doctors and hospitals at 584 insurance pharmacies from August 4 to 10, 2014.  Then, the inquiries about prescriptions and requests for doctors and hospitals were categorized.
Results: The most frequent category of inquiries about prescriptions was “Questions about administration and dosage” (21.5%).  On the contrary, the most frequent request for doctors was “Efficiency in gathering information from and providing information to a patient” (2,067 cases).
Conclusions: The present study clarified current problems revealed by inquiries about prescriptions by investigating requests for doctors and hospitals that were based on examples.  Furthermore, the problems were classified into ten categories, and these should be noted by doctors and hospitals at the time the prescription was issued.

The supinator muscle originates from the annular ligament of the radius, and the muscle fibers and ligament take a similar winding course. Likewise, the coccygeus muscle and the sacrospinous ligament are attached together, and show a similar fiber orientation. During dissection of adult cadavers for our educational curriculum, we had the impression that these ligaments grow in combination with degeneration of parts of the muscles. In histological sections of 25 human fetuses at 10-32 weeks of gestation, we found that the proximal parts of the supinator muscle were embedded in collagenous tissue when the developing annular ligament of the radius joined the thick intermuscular connecting band extending between the extensor carpi radialis and anconeus muscles at 18-22 weeks of gestation, and the anterior parts of the coccygeus muscle were surrounded by collagenous tissue when the intramuscular tendon became the sacrospinous ligament at 28-32 weeks. Parts of these two muscles each seemed to provide a mold for the ligament, and finally became involved with it. This may be the first report to indicate that a growing ligament has potential to injure parts of the "mother muscle," and that this process may be involved in the initial development of the ligament.

Using immunohistochemical staining for alpha-smooth muscle actin (alpha-SMA), glial fibrillary acidic protein (GFAP), S100 protein (S100), p63, cytokeratin 14 (CK14), and cytokeratin 19 (CK19), we studied acinar and myoepithelial cells of major and minor salivary glands obtained from 14 donated cadavers (78-92 years old) and 5 donated fetuses (aborted at 15-16 weeks of gestation). CK and p63 expression was investigated only in the adult specimens. SMA was detected in all adult glands as well as in fetal sublingual and pharyngeal glands. GFAP expression was seen in a limited number of cells in adult glands, but was highly expressed in fetal pharyngeal glands. S100-positive myoepithelial-like cells were present in adult minor glands as well as in fetal sublingual and pharyngeal glands. Expression of p63 was evident in the ducts of adult glands. CK14 immunoreactivity was observed in a limited number of glandular cells in adults, in contrast to consistent expression of CK19. In both adults and fetuses, a mosaic expression pattern was usually evident for each of the examined proteins. A difference in immunoreactivity for the nerve markers GFAP and S100 was observed between the major and minor glands. Thus, in the present histologic study, we distinguished between the specific gland types on the basis of their immunohistochemical staining. A mosaic expression pattern suggested that the immunoreactivity against nerve protein markers in myoepithelial cells could not be due to the persistence of neural crest remnants or the physiological status of the gland, such as age-related degeneration.

Objective: Since the conventional drip-infusion method for measuring inulin clearance (Cin) has problems related to its accuracy and performance, we explored a more accurate and concise method by rapid intravenous injection of a newly developed inulin fraction (Inulead^®), in which spot urine sampling was omitted and the administration period of inulin was shortened from 120 to 5 minutes. Patients and Methods: Twenty seven patients (M/F: 15/12, 67.8 ± 12.9 years old) admitted to the Nephrology ward were enrolled in this study. Inulead^®, 1500 mg dissolved in 150 mL of saline, was intravenously administered in 5 minutes. Then, sequential blood samplings and urine collection were performed for 24 hours. Cins were calculated by the following three formulae: (1) a pharmacokinetic analysis using a two compartments model based on the plasma inulin concentration to determine Cin, which was the administered dose divided by the area under the curve (AUC) from 0 to ∞, (2) urinary inulin excretion divided by the AUC for 24 hours and (3) the Bayesian method using a three-point set of plasma inulin concentrations to predict the change of inulin concentration to determine Cin as in 1. These Cins were compared with levels of estimated GFR (eGFR), creatinine clearance (Ccr), serum β2 microglobulin (β2MG) and serum cystatin C (Cys C). Results: Cins obtained by the above three methods were well correlated with each other (r. = 0.9088 – 0.9998) and with eGFR (r. = 0.8286 – 0.8650), Ccr (r. = 0.821 – 0.864), 1/β2MG (r. = 0.631 –0.752) and 1/CysC (r. = 0.830 – 0.857). The averaged differences of each Cin from eGFR were distributed between –4.4 and –4.5 mL/min. Conclusion: Since the Cins by rapid inulin injection showed satisfactory correlation and differences with other GFR parameters, this method will be a good alternative to the drip infusion method, and may reduce the burden of patients and medical staff.

A76-year-old man was transferred to our hospital for evaluation of continuous abdominal pain with systemic inflammation. Clinical examinations suggested the pressure of an adynamic ileus due to diverculitis and an infrarenal abdominal aortic aneurysm. Thirty-eight millimeter in diameter despite the commencement of antibiotic therapy, the symptoms progressively worsened and repeated CT scan demonstrated a rupture of the aneurysm without any enlargement in diameter. An emergency operation was done, and the patient was discharged on the 77th postoperative day. Blood culture and histological findings disclosed an infected aortic aneurysm due to Listeria monocytogenes. The possibility of aortic infection should be considered in patients showing a sudden rupture of an aortic aneurysm.

OBJECTIVESTo assess trends in smoking prevalence among Japanese adolescents and to analyze possible causal factors for the decrease in smoking prevalence observed in a 2004 survey.

METHODSNationwide cross-sectional surveys were conducted in 1996, 2000 and 2004. Survey schools, both junior and senior high schools, considered to be representative of the whole of Japan were sampled randomly. Enrolled students were asked to complete a self-reporting anonymous questionnaire on smoking behavior. The questionnaires were collected from 115,814 students in 1996, 106,297 in 2000, and 102,451 in 2004. School principals were asked about the policy of their respective school on smoking restrictions.

RESULTSCigarette smoking prevalence (lifetime, current, and daily smoking) in 2004, based on the completed questionnaires, had decreased relative to previous years in both sexes and in all school grades. The most important trends were: a decrease in smoking prevalence among the fathers and older brothers of the students; an increase in the proportion of students who did not have friends; a decrease in the proportion of current smokers who usually bought cigarettes in stores decreased in 2004, in particular for the oldest boys. An association was found between a lower smoking rate at a school and a smoke-free school policy.

CONCLUSIONSJapan has experienced a decrease in the prevalence of smoking among adolescents. A decrease in smoking prevalence among the fathers and older brothers, limitations to minors' access to tobacco, an increase in the proportion of students without friends, and a school policy restricting smoking may have contributed to this decreasing trend.
