Correlation between fungi isolated from burn wounds and burn care units

A comparison was made prospectively between fungal isolates from patients and burn care units. Aspergillus niger was the most frequent isolate in both patients and burn care units whereas Ulocladium was the commonest isolate in the control group. Aspergillus terreus, Penicillium and Zygomycetes, which were recovered from burned patients, were also found more frequently in the burn care units than in the control group (other areas in the hospital). These findings indicate a potential risk of fungal infection which can be acquired from the immediate surroundings of patients in burn care units. Periodical burn ward decontamination is therefore recommended.     

Orally active isoxazoline glycoprotein IIb/IIIa antagonists with extended duration of action

Modification of the alpha-carbamate substituent of isoxazoline GPIIb/IIIa (alphaIIb beta3) antagonist DMP 754 (7) led to a series of alpha-sulfonamide and alpha-sulfamide diaminopropionate isoxazolinylacetamides which were found to be potent inhibitors of in vitro platelet aggregation. Aryl- and heteroaryl-alpha-sulfonamide groups, in conjunction with (5R)-isoxazoline (2S)-diaminopropionate stereochemistry, were found to impart a pronounced duration of antiplatelet effect in dogs, potentially due to high affinity for unactivated platelets. Isoxazolylsulfonamide 34b (DMP 802), a highly selective GPIIb/IIIa antagonist, demonstrated a prolonged duration of action after iv and po dosing and high affinity for resting and activated platelets. The prolonged antiplatelet profile of DMP 802 in dogs and the high affinity of DMP 802 for human platelets may be predictive of clinical utility as a once-daily antiplatelet agent.     

Combined Multichannel Intraluminal Impedance-pH (MII-pH): Multicenter Report of Normal Values from 117 Children

Pancreatic cancer is the fourth leading cause of cancer deaths in the USA. Although some patients will present with premalignant pancreatic lesions (i.e., intraductal papillary mucinous neoplasms) or localized tumors amenable to curative resection, the majority of patients will unfortunately present with technically unresectable or metastatic disease. This review of the recent medical literature will discuss the optimal work-up and management of premalignant pancreatic lesions and the surgical management of localized, borderline resectable, and locally advanced (i.e., unresectable) pancreatic tumors. It will focus on new criteria used to define surgical “resectability,” the significance and clinical impact of surgical margins, the role of multimodality therapy in the management of patients with borderline resectable or locally advanced tumors, the role of surgery for local or distant recurrence, and minimally invasive surgical approaches.

Elevated serum neutrophil elastase is related to prehypertension and airflow limitation in obese women

Background  

Neutrophil elastase level/activity is elevated in a variety of diseases such as atherosclerosis, systolic hypertension and obstructive pulmonary disease. It is unknown whether obese individuals with prehypertension also have elevated neutrophil elastase, and if so, whether it has a deleterious effect on pulmonary function. Objectives: To determine neutrophil elastase levels in obese prehypertensive women and investigate correlations with pulmonary function tests.     

Efficacy of clofibrate on severe neonatal jaundice associated with glucose-6-phosphate dehydrogenase deficiency (a randomized clinical trial)

Glucose-6-phosphate dehydrogenase (G6PD) deficiency may cause severe hyperbilirubinemia with bilirubin encephalopathy unless intervention is initiated. The aim of this study was to assess the efficacy of clofibrate in full term G6PD deficient neonates with jaundice. A randomized clinical trial study was performed in two groups of full-term G6PD deficient jaundiced neonates (clofibrate treated group, n = 21; control group, n = 19). Infants in the clofibrate group received a single oral dose of 100 mg/kg clofibrate, whereas control group received nothing. Both groups were treated with phototherapy. Serum total and direct bilirubin levels were measured at the onset of treatments, 16, 24 and 48 hours later. On enrollment, the mean total serum bilirubin (TSB) level in the clofibrate treated group was 18.40 +/- 2.41 and in the control group was 17.49 +/- 1.03 (p = 0.401). At 16, 24 and 48 hours of treatment, the mean TSB in the clofibrate group were 15.2 +/- 1.9, 12.6 +/- 2.4, and 10.1 +/- 2.4 and in the control group were 16.5 +/- 1.2, 13.3 +/- 2.2 and 11.4 +/- 2.4, respectively (p = 0.047). At 48 hours, 7 (33%) cases in the clofibrate group and one (5%) case in the control group were discharged with a TSB < 10 mg/dl (p = 0.031). No side effects were observed on serial examinations during hospitalization, or on the 1st and 7th days after discharge. The results show that clofibrate induces a faster decline in serum total bilirubin level, a shorter duration of phototherapy, and hospitalization with no side effects in full-term G6PD deficient neonates with jaundice.     

Advances in pharmacotherapy for primary biliary cirrhosis

Introduction: Primary biliary cirrhosis (PBC) is a chronic autoimmune liver disease mostly seen in middle-aged women characterized by progressive nonsuppurative destruction of small bile ducts resulting in intrahepatic cholestasis, parenchymal injury and ultimately end-stage liver disease. Despite major breakthroughs in our understanding of PBC, there remains only one FDA-approved agent for treatment: ursodeoxycholic acid (UDCA) to which one-third of patients are unresponsive.

Areas covered: Biochemical response to treatment with UDCA is associated with excellent survival rates in PBC patients. However, there is a need for alternative treatments for nonresponders. Results from human epidemiological and genetic studies as well as preclinical studies in PBC animal models have provided a strong impetus for the development of new therapeutic agents. In this review, we discuss the recent advances in translational research in PBC focusing on promising therapeutic approaches, namely immune-based targeted therapies and agents targeting the synthesis and circulation of bile acids.

Expert opinion: We are in a new era for the development of novel therapies for PBC. Data on fibrates, budesonide and obeticholic acid offer encouragement for nonresponders to UDCA.
