Postmarketing surveillance of levofloxacin (LVFX) has been conducted continuously since 1992. The present survey was performed to investigate in vitro susceptibility of recent clinical isolates in Japan to 30 selected antibacterial agents, focusing on fluoroquinolones (FQs). The common respiratory pathogens Streptococcus pyogenes, Streptococcus pneumoniae, Moraxella catarrhalis, and Haemophilus influenzae continue to show a high susceptibility to FQs. In contrast, widely-prevailing resistance to macrolides was markedly noted among S. pneumoniae and S. pyogenes. Regarding H. influenzae, the prevalence of β-lactamase-negative ampicillin-resistant isolates has been increasing year by year (25.8% in 2002, 40.0% in 2004, 50.1% in 2007, and 57.9% in 2010). Enterobacteriaceae showed high susceptibility to FQs, however, prevalence of LVFX-resistant Escherichia coli, including intermediate resistance, was 29.3%, showing an increase over time. Nevertheless, the increase in the prevalence of LVFX-resistant E. coli isolates has slowed since 2007 (8.2% in 2000, 11.8% in 2002, 18.8% in 2004, 26.2% in 2007, and 29.3% in 2010), suggesting the influence of LVFX 500 mg tablets since its approval in 2009. Another Enterobacteriaceae member, Klebsiella pneumoniae, showed low resistance to FQs, in contrast with E. coli. In methicillin-resistant Staphylococcus aureus (MRSA), the percentage of FQ-susceptible isolates was low, at 51.6% for susceptibility to sitafloxacin, and at only around 10% for susceptibility to other FQs. However, methicillin-susceptible S. aureus (MSSA) isolates were highly susceptible to FQs, with the percentage ranging from 88.5% to 99.1%. The prevalence of FQs-resistant isolates in methicillin-resistant coagulase-negative staphylococci was higher than that in methicillin-susceptible coagulase-negative staphylococci, although it was lower than the prevalence of FQ-resistance in MRSA. The prevalence of FQs-resistant Pseudomonas aeruginosa isolates derived from urinary tract infections (UTIs) was 15.4-21.3%, higher than the prevalence of 6.1-12.3% in P. aeruginosa isolates from respiratory tract infections (RTIs). While this trend was consistent with the results of previous surveillance, gradual decreases were noted in the prevalence of FQ-resistant P. aeruginosa isolates derived from UTIs. The prevalence of multidrug-resistant P. aeruginosa was 2.3% among isolates derived from UTIs and 0.3% among isolates from RTIs, a decrease from the results of 2007, Acinetobacter spp. showed high susceptibility to FQs. Imipenem-resistant Acinetobacter baumannii, which is currently an emerging issue, was detected at a prevalence of 2.4% (13 isolates). Neisseria gonorrhoeae showed a high resistance of 81.3-82.5%, to FQs. Ceftriaxone (CTRX) continued to show 100% susceptibility until 2007, but the present survey revealed the advent of resistance to CTRX in some clinical isolates. The result of the present survey indicated that although methicillin-resistant staphylococci, Enterococcus faecium, P. aeruginosa from UTIs, N. gonorrhoeae, and E. coli showed resistance of about 20% or more (19.5-89.2%) against the FQs which have been used clinically for over 17 years, the trends observed were similar to the results of previous surveillance. While FQ resistance has been prevailing in E. coli, E. coli still shows more than 70% susceptibility to FQs. The other bacterial species maintained high susceptibility rates of greater than 80%, against FQs.

Objective. Cigarette smoking may be associated with increased risk of systemic lupus erythematosus (SLE), whereas the role of alcohol consumption is unknown. We examined the association between SLE risk and smoking or drinking. Methods. We investigated the relationship of smoking and drinking compared to SLE risk among 171 SLE cases and 492 healthy controls in female Japanese subjects. Unconditional logistic regression was used to compute OR and 95% CI, with adjustments for several covariates. Results. Compared with nonsmoking, current smoking was significantly associated with increased risk of SLE (OR 3.06, 95% CI 1.86-5.03). The higher the level of exposure to cigarette smoke, the higher the risk of SLE. Inhalation was also associated with increased SLE risk (OR 3.73, 95% CI 1.46-9.94 for moderate inhalation; OR 3.06, 95% CI 1.81-5.15 for deep inhalation). In contrast, light/moderate alcohol consumption had a protective effect on SLE risk (OR 0.38, 95% CI 0.19-0.76). As for beer, the risks for non-beer drinkers and beer drinkers were similar. This also applies to alcoholic beverages other than beer. Conclusion. Our results suggest that smoking was positively associated with increased SLE risk whereas light/moderate alcohol consumption was inversely associated with SLE risk, irrespective of the type of alcoholic beverage. Additional studies are warranted to confirm these findings. The Journal of Rheumatology Copyright © 2012. All rights reserved.

Background The value of pancreatoduodenectomy (PD) with extended lymphadenectomy for pancreatic cancer has been evaluated by many retrospective studies and 3 randomized controlled trials (RCT). However, the protocols used and the results found in the 3 RCTs were diverse. Therefore, a multicenter RCT was proposed in 1998 to evaluate the primary end point of long-term survival and the secondary end points of morbidity, mortality and quality of life of patients undergoing standard versus extended lymphadenectomy in radical PD for pancreatic cancer. Methods From March 2000 to May 2003, 112 patients with potentially curable pancreatic head cancer were enrolled and intraoperatively randomized to a standard or extended lymphadenectomy group. No resected patients received any adjuvant treatments. Results A hundred and one eligible patients were analyzed. Demographic and histopathological characteristics of the two groups were similar. The mean operating time, intraoperative blood loss and number of retrieved lymph nodes were greater in the extended group, but the other operative results were comparable. Conclusions Although this multicenter RCT was conducted in a strict setting, extended lymphadenectomy in radical PD did not benefit long-term survival in patients with resectable pancreatic head cancer and led to levels of morbidity, mortality and quality of life comparable to those found after standard lymphadenectomy. © 2011 Japanese Society of Hepato-Biliary-Pancreatic Surgery and Springer.

Non-invasive ventilation (NIV) assists breathing and thus improves oxygenation in patients with Kyphoscoliosis. The benefits of short- and long-term intermittent nocturnal in such patients have been reported previously (improvement of vital capacity, total lung capacity, muscle strength, daytime oxygenation, exercise capacity, and pulmonary hypertension). We review this important study reporting patients with kyphoscoliosis and acute respiratory failure along with their long-term outcomes. We believe that this letter may provide important information regarding the prognosis and efficacy of NIV. © 2013 Esquinas et al.; licensee BioMed Central Ltd.

Argatroban was used as the anticoagulant during cardiopulmonary bypass (CPB) in a patient with heparin-induced thrombocytopenia (HIT) type II undergoing mitral valve replacement. Dosage was reduced because of preoperative congestive liver disorder. Perioperative coagulability was poor, and, ultimately, failure of hemostasis led to a fatal outcome. Although argatroban use as an anticoagulant for HIT is reported, the optimal dose has not been established. During long-term CPB, increasing the total dosage may extend anticoagulant ability, leading to dose dependence. Because no antagonist for argatroban exists, failure of hemostasis might occur. © 2013 Japanese Society of Anesthesiologists.

Background and aims: Vibrio vulnificus causes an infectious disease that has extremely poor convalescence and leads to necrotic fasciitis. In this study, we sought to define the characteristic epidemiology of V. vulnificus infection and clarify its diagnosis at the global level. Methods: Over a period of 10 years, we investigated the appearance of symptoms, underlying conditions, treatment, and mortality in 12 patients (eight men, four women; >50 years old; average age, 66 years,) infected with V. vulnificus. Results: The development of symptoms occurred primarily between June and September, a period during which seawater temperature rises and the prevalence of V. vulnificus increases. All patients had underlying diseases, and seven patients reported a history of consuming fresh fish and uncooked shellfish. The patients developed sepsis and fever with sharp pain in the limbs. Limb abnormalities were observed on visual examination. All patients underwent debridement; however, in the survival group, the involved limb was amputated early in 80% patients. The mortality rate was 58.3%. Conclusion: Recognition of the characteristic epidemiology and clinical features of this disease is important, and positive debridement should be performed on suspicion. When the illness reaches an advanced stage, however, amputation should be the immediate treatment of choice. © 2013 Elsevier Editora Ltda.

Primary Sjögren syndrome is an immune-mediated exocrinopathy characterized by lymphoplasmacytic infiltration of the salivary and lacrimal glands. Various systemic extraglandular disorders are associated with primary Sjögren syndrome, and the thorax is commonly affected. The pulmonary manifestations of primary Sjögren syndrome may be categorized as airway abnormalities, interstitial pneumonias, and lymphoproliferative disorders; in each category, bronchiectasis or centrilobular nodules, nonspecific interstitial pneumonia, and lymphoid interstitial pneumonia are common. These manifestations do not usually occur in isolation; they are concomitantly seen with other types of lesions. Mucosa-associated lymphoid tissue (MALT) lymphoma and amyloidosis are key components of lymphoproliferative disorders, and MALT lymphoma should always be considered because its morphologic characteristics are similar to those of benign lymphoproliferative disorders. Amyloidosis is rare but important because it carries a risk for underlying MALT lymphoma or plasmacytoma, and it may lead to hemoptysis during biopsy. In addition, thin-walled air cysts are characteristic of primary Sjögren syndrome, irrespective of the main pulmonary manifestations. Lymphadenopathy and multilocular thymic cysts may be seen in19 the mediastinum. During the follow-up period, there is a risk for acute exacerbation of interstitial pneumonia and development of malignant lymphoma. Often, primary Sjögren syndrome is subclinical, but there are various underlying risks. Thus, imaging findings are important. In addition to the various types of interstitial pneumonia and airway abnormalities, air cysts and mediastinal manifestations may help diagnose primary Sjögren syndrome. © RSNA, 2013.

Background: Severe acute hepatic failure (SAHF), which progresses to fulminant form in some cases, is a life-threatening disease. Purpose: To assess the technical feasibility and the efficacy of transcatheter arterial steroid injection therapy (TASIT) for SAHF. Material and Methods: Twenty-seven patients with SAHF, 10 of whom had variant anatomy of the hepatic artery, underwent radiologic placement of an indwelling catheter in the hepatic artery, and TASIT was subsequently performed for three days. The tips of the catheters were inserted as follows: common hepatic artery (n = 18), proper hepatic artery (n = 4), and replaced right hepatic artery (n = 5). The clinical success rate of TASIT and the prognosis after TASIT were evaluated. Results: In one patient, intimal injury of the left hepatic artery was encountered; however, TASIT could be resumed and completed via intrahepatic arterial collaterals. In two patients, the catheter tip placement was corrected on the following day because of dislocation. Finally, TASIT could be carried out in all patients. Twenty-two patients (81.5%) responded to TASIT but five patients (18.5%) did not. Among the five nonresponders, two patients were transferred to liver transplantation and survived, and three patients died. There was no significant difference in the response rates to TASIT among locations of catheter tip (P > 0.05) and extent of drug distribution in the liver (P > 0.05). Conclusion: TASIT is a feasible and efficient treatment option for SAHF regardless of the anatomic variation of the hepatic artery. Careful manipulation during the procedure to prevent injury of the hepatic artery may be the most essential factor not only for successful TASIT but also for liver transplantation, which may be performed on TASIT non-responders.
