ABSTRACT

BACKGROUND: How increasing age affects the characteristics of groin hernia remains uncertain. This study evaluated the association between age and the type of groin hernia, especially with respect to its multiplicity, observed during laparoscopic transabdominal preperitoneal (TAPP) hernia repair. METHODS: We retrospectively evaluated 634 consecutive patients with primary groin hernia who underwent laparoscopic TAPP repair between October 2000 and June 2017. Patients were stratified into 4 age groups: < 60 years, 60-69 years, 70-79 years, and 80 years or older. RESULTS: The incidence of occult contralateral hernia and multiple ipsilateral hernias increased significantly with each increasing age group: 7.3%, 10.4%, 12.7%, and 20.8% for occult contralateral hernia (p = 0.005), and 5.6%, 9.2%, 16.8%, and 21.7% for multiple ipsilateral hernias (p < 0.001), respectively. Univariate analyses showed that an older age (age ≥ 70 years) was the only factor significantly associated with the presence of multiple groin hernias (odds ratio, 2.69; 95% confidence interval, 1.89-3.81; p < 0.001). In patients with multiple ipsilateral hernias, the prevalent form in men was a pantaloons hernia, with an incidence of about 70% across all age groups, whereas in women it was groin hernias, with one component being a femoral hernia, an obturator hernia, or both. CONCLUSIONS: The multiple occurrence of groin hernias, either unilaterally or bilaterally, was a clinical feature in the elderly.

ABSTRACT

We examined the mechanism by which contingent negative variation (CNV) amplitude in the prefrontal cortex during the preparatory period of a stop-signal task affected the accuracy of response inhibition in the task. The participants were required to press a button when a go signal was presented and withhold the response when the go signal was followed by a stop signal. Continuous electroencephalograms were recorded of the six electrodes (Fz, F3, F4, Cz, C3, and C4) in the regions of interest during the performance of the task. First, the fast and slow go responses in the preparatory periods were compared. The activities in the preparatory periods of the successful and failed inhibitions were then compared and analyzed. The late CNV amplitudes of F4 and Cz were significantly larger for fast go responses than for slow go responses. Moreover, the late CNV amplitudes of almost all of the channels, with the exception of C3 and C4, were significantly larger for failed inhibitions than for successful inhibitions. These findings suggested that increased prefrontal activity during the preparatory period facilitated the execution process after the presentation of the go signal. Because execution processing is completed more quickly than stop processing, the response inhibition then failed.

ABSTRACT

BACKGROUND: A laparoscopic surgical approach for obturator hernia (OH) repair is uncommon. The aim of the present study was to assess the effectiveness of laparoscopic transabdominal preperitoneal (TAPP) repair for OH. METHODS: From 2001 to May 2010, 659 patients with inguinal hernia underwent TAPP repair at in our institutes. Among these, the eight patients with OH were the subjects of this study. RESULTS: Three of the eight patients were diagnosed as having occult OH, and the other five were diagnosed preoperatively, by ultrasonography and/or computed tomography, as having strangulated OH. Bilateral OH was found in five patients (63%), and combined groin hernias, either unilaterally or bilaterally, were observed in seven patients (88%), all of whom had femoral hernia. Of the five patients with bowel obstruction at presentation, four were determined not to require resection after assessment of the intestinal viability by laparoscopy. There was one case of conversion to a two-stage hernia repair performed to avoid mesh contamination: addition of mini-laparotomy, followed by extraction of the gangrenous intestine for resection and anastomosis with simple peritoneal closure of the hernia defect in the first stage, and a Kugel hernia repair in the second stage. There was no incidence of postoperative morbidity, mortality, or recurrence. CONCLUSIONS: Because TAPP allows assessment of not only the entire groin area bilaterally but also simultaneous assessment of the viability of the incarcerated intestine with a minimum abdominal wall defect, we believe that it is an adequate approach to the treatment of both occult and acutely incarcerated OH. Two-stage hernia repair is technically feasible in patients requiring resection of the incarcerated intestine.

ABSTRACT

Group A rotavirus G-serotyping by polymerase chain reaction (PCR) using university hospital subject samples in September 2003 to August 2004, September 2004 to August 2005, September 2005 to August 2006, and September 2006 to August 2007 showed the most common serotypes G1 and G3, detected in 27 and 33 subjects, compared to 4 subjects in whom serotype G4 was detected. Between 2003 and 2004, serotypes G1 accounted for 50% and G3 for 38%, contrasting with serotype G3 at 79% between 2004 and 2005, serotype G1 at 91% between 2005 and 2006, and serotype G1 and G3 at 37% and 63% between 2006 and 2007, respectively. Serotypes G2 and G9 were not detected at all during any of our time periods. No correlation was seen between subject age and G serotype, although subjects younger than two years old accounted for 73% of subjects. This infection caused combined fever, diarrhea, and vomiting in 48% of subjects but showed no correlation with G serotype. These findings under-score the importance of G-serotyping in understanding rotavirus infection epidemiology at different times and in different locales.

ABSTRACT

A 52-year-old man had been treated by hemodialysis because of IgA nephropathy since 1994. Gastric MALT lymphoma was diagnosed in January 2007. Radiation therapy was performed for 4 weeks (40Gy) and the response was complete remission (CR) by September 2007. He was admitted to our hospital in February 2008 because of an abnormal chest shadow. Chest CT showed multiple cystic lesions with calcification and consolidation. Transbronchial lung biopsy from the area of consolidation (left S5) showed pulmonary invasion of small lymphoid cells. PCR analysis showed clonal rearrangement of the heavy chain of the immunoglobulin gene. Accordingly, MALT lymphoma was diagnosed. Rituximab infusion was performed, because CD20 immunostaining was positive and he had been treated by hemodialysis. The abnormal chest shadow was presented since gastric MALT lymphoma was diagnosed. We considered that MALT lymphoma occurred simultaneously in the stomach and lung.

ABSTRACT

We report two cases of bilateral racemose hemangioma in patients with hemoptysis. Case 1 was a 62-year-old woman who visited a local clinic complaining of hemoptysis. Bronchoscopy revealed multiple pulsating tumorous lesions and she was referred to our department. Chest Multidetector CT (MDCT) disclosed bilateral enlarged and convoluted, abnormal bronchial arteries and primary racemose hemangioma was diagnosed. Bronchial artery embolization was selected, but not conducted because of concern regarding the arteriovenous shunt and escape into the greater circulation. In combination with thoracoscopic mini-thoracotomy, ligation and separation of the bronchial artery were performed. Case 2 was a 68-year-old man who was transferred to our department with a chief complaint of hemoptysis. MDCT revealed bilateral bronchiectasis and a convoluted and enlarged, abnormal bronchial artery along the mediastinum. He was diagnosed as having secondary racemose hemangioma. First, bronchial artery embolization was conducted, but hemostasis was difficult, thus surgical ligation was conducted. In both cases, MDCT was effective for diagnosis and surgical ligation is very important as a therapeutic option for racemose hemangioma.

ABSTRACT

The most important targets of hospital-acquired infection control are to reduce the incidence of surgical-site, catheter-related, and ventilator-associated infections. In this report, we address previously presented infection-control strategies for central venous (CV) line catheterization, using a CV catheter-related infection surveillance system. Data concerning CV catheter insertion were collected from all facilities in our 650-bed hospital, excluding the operating and hemodialysis wards. Collected data included the insertion method, purpose, length of catheter inserted, duration of catheterization, infection rate, and complication rate. Catheter-related infection was diagnosed based on bacteriological examinations from blood cultures. The total number of catheterizations was 806 a year, and average duration of catheterization was 9.8 days. The purpose of catheterization was nutritional support in 210 cases, hemodialysis in 96 cases, cardiac support in 174 cases, and other treatments in 260 cases. In 66 cases, the purpose of CV catheter was not specified. The rate of positive cultures was 7.1%, and complications other than infection occurred in 0.5%. The main causative organisms were methicillin-resistant Staphylococcus aureus (MRSA) in 38.6%, coagulase-negative Staphylococcus epidermidis (CNS) in 33.3%, and S. aureus in 12.3% of infections. Infection rates were 3.8 per 1000 catheter-days in subclavian, 6.1 in jugular, and 15.7 in femoral vein catheterization. In high-risk departments (intensive care unit [ICU] and emergency departments) the infection rate was 5.4 for subclavian and 10.2 for jugular catheterization, whereas it was 3.6 for subclavian and 4.6 for jugular catheterization in noncritical-care departments. Considering complications such as pneumothorax, CV catheterization of the jugular vein is recommended in certain situations.

ABSTRACT

Small cell lung cancer was diagnosed in a 54-year-old man in 1997. He had received 5 cycles of systemic chemotherapy and thoracic irradiation since 1997, and a favorable response had been achieved. In August 2001, pro-GRP was again elevated, and he was readmitted. Bronchoscopic findings revealed a white dendritic endobronchial mass on a cheese-like plug obstructing the left upper bronchus division. Numerous mucor hyphe and cancer cells were detected by transbronchial biopsy, and a fungal culture disclosed mucor. Although no antifungal drug was administered, the bronchial lesion disappeared after removal with biopsy forceps and 2 cycles of systemic anticancer chemotherapy. Endobronchial involvement of mucormycosis is rare and this case is unique because of the peculiar bronchoscopic finding with the endobronchial lesion.
