Ultrasonography can replace chest X-rays in the postoperative care of thoracic surgical patients.

Objectives: Lung ultrasound accurately identifies pulmonary and pleural pathologies. Presently it has not been accepted as a routine examination in the postoperative follow-up of thoracic surgical patients. The present study aimed to compare thoracic ultrasonography with chest X-ray for detecting and clinical relevance of pneumothorax, pleural effusion, and lung consolidation and determine whether ultrasonography could replace chest X-ray as the standard examination after surgery.

Genetic mutation screen in early non--small-cell lung cancer (NSCLC) specimens.

Background: Testing for genetic abnormalities in epithelial growth factor receptor (EGFR), anaplastic lymphoma receptor tyrosine kinase (ALK), and potentially additional genes is a critical tool in the care of advanced NSCLC. There is conflicting evidence for the role of such tests in early NSCLC. We report a single-institute Sequenom testing for a wide range of mutations and their clinical correlations in early-resected NSCLC specimens.

Resection and heated pleural chemoperfusion in patients with thymic epithelial malignant disease and pleural spread: a single-institution experience.

Objective: Our objective was to evaluate whether resection and heated pleural chemoperfusion (HPCP) is an effective treatment for de novo stage IVa thymoma (DNT) and thymic carcinoma (TC) and for thymoma with pleural relapse (TPR).

Methods: A retrospective study was conducted of patients undergoing resection and HPCP in 1 center. HPCP with cisplatinum ± doxorubicin (adriamycin) was performed for 60 minutes using a standard roller pump and a modified heat exchanger to a maximal intrapleural temperature of 43°C.

A mitochondrial GABA permease connects the GABA shunt and the TCA cycle, and is essential for normal carbon metabolism.

In plants, γ-aminobutyric acid (GABA) accumulates in the cytosol in response to a variety of stresses. GABA is transported into mitochondria, where it is catabolized into TCA cycle or other intermediates. Although there is circumstantial evidence for mitochondrial GABA transporters in eukaryotes, none have yet been identified.

Adjuvant radiotherapy for thymic epithelial tumor: treatment results and prognostic factors.

Objective: To determine whether the use of adjuvant radiation in the treatment of invasive thymic tumors affects survival and to identify prognostic factors.

Methods: The files of 47 patients with thymic tumors treated by adjuvant radiation in our institute from 1984 to 2003 were reviewed for data on prognosis and survival. All patients underwent thoracotomy followed by either total macroscopic resection (n = 42) or biopsy (n = 5).

Ertapenem or ticarcillin/clavulanate for the treatment of intra-abdominal infections or acute pelvic infections in pediatric patients.

Background: Ertapenem, a group I carbapenem antibiotic, has been shown to be safe and effective in treating adults with complicated intra-abdominal (cIAI) or acute pelvic infection (API). This study evaluated ertapenem for treating these infections in children.

Methods: In an open-label study, children aged 2 to 17 years with cIAI or API were randomized 3:1 to receive ertapenem or ticarcillin/clavulanate.

The sequence of vessel interruption during lobectomy: does it affect the amount of blood retained in the lobe?

Objective: In a previous study, we have shown that the sequence of vessel interruption (SVI) during lobectomy has no impact on tumor recurrence. The aim of the present study was to determine whether SVI has an impact on the amount of blood retained in the resected lobe.

Patients And Methods: A non-randomized prospective study including 30 patients undergoing lobectomy for neoplasms.

Cricotracheal resection for airway reconstruction: The Sheba Medical Center experience.

Background: Intubation and tracheostomy are the most common causes of benign acquired airway stenosis. Management varies according to different conceptions and techniques.

Objectives: To review our experience with cricotracheal resection and to assess related pitfalls and complications.

Lung transplantation in patients with cystic fibrosis: the Israeli experience.

Background: Lung transplantation is a well-established therapeutic option for end-stage lung disease in cystic fibrosis. Although it confers a clear survival advantage, outcome differs among centers according to local experience, patient selection, transplantation procedure, and postoperative care.

Objectives: To evaluate the national Israeli experience with lung transplantation in patients with CF.

Current guidelines produce competent endovascular surgeons.

Objective: This study was conducted to evaluate the safety of percutaneous endovascular procedures (PEPs) during integration of endovascular skills into an urban academic vascular surgery practice and assess the hypothesis that currently accepted guidelines are a valid benchmark for endovascular competency.

Methods: From 2000 through 2004, an endovascular training paradigm was instituted to integrate endovascular procedures into an academic endovascular practice. The paradigm involved individual mentoring of vascular surgery faculty by a partner with mature endovascular skills.

Genetic analyses of non-small cell lung cancer in Jewish Israeli patients.

Background: The contribution of the abnormal DNA mismatch repair system to non-small cell lung cancer tumorigenesis is controversial and has not been reported in Jewish Israeli patients. Similarly, the involvement of 3p deletions in NSCLC in the same population has not been assessed.

Objectives: To assess the contribution of the DNA-MMR system to NSCLC pathogenesis by analyzing microsatellite instability, and evaluate loss of heterozygosity at 3p rates in Israeli NSCLC patients.

Experience with somatostatin receptor scintigraphy in the management of pulmonary carcinoid tumors.

Background: Somatostatin receptor scintigraphy has been used widely for the evaluation of neuroendocrine tumors in the gastrointestinal tract. Its use for detecting and staging thoracic carcinoids is only sporadically reported.

Objectives: To evaluate the possible roles of SRS in the management of proven or suspected pulmonary carcinoids.

A multicenter trial of the efficacy and safety of tigecycline versus imipenem/cilastatin in patients with complicated intra-abdominal infections [Study ID Numbers: 3074A1-301-WW; ClinicalTrials.gov Identifier: NCT00081744].

Background: Complicated intra-abdominal infections (cIAI) remain challenging to treat because of their polymicrobial etiology including multi-drug resistant bacteria. The efficacy and safety of tigecycline, an expanded broad-spectrum glycylcycline antibiotic, was compared with imipenem/cilastatin (IMI/CIS) in patients with cIAI.

Methods: A prospective, double-blind, multinational trial was conducted in which patients with cIAI randomly received intravenous (IV) tigecycline (100 mg initial dose, then 50 mg every 12 hours [q12h]) or IV IMI/CIS (500/500 mg q6h or adjusted for renal dysfunction) for 5 to14 days.

Plant-specific calmodulin-binding proteins.

Calmodulin CaM is the most prominent Ca2+ transducer in eukaryotic cells, regulating the activity of numerous proteins with diverse cellular functions. Many features of CaM and its downstream targets are similar in plants and other eukaryotes. However, plants possess a unique set of CaM-related proteins, and several unique CaM target proteins.

Major bronchial trauma in the pediatric age group.

Tracheobronchial injuries are rare among all age groups and are extremely rare among the pediatric age group. Yet, the incidence has seemed to increase. Most of these patients die before reaching the hospital from severe associated injuries.

GABA shunt deficiencies and accumulation of reactive oxygen intermediates: insight from Arabidopsis mutants.

In plants, succinic semialdehyde dehydrogenase (SSADH)-deficiency results in the accumulation of reactive oxygen intermediates (ROI), necrotic lesions, dwarfism, and hypersensitivity to environmental stresses. We report that Arabidopsis ssadh knockout mutants contain five times the normal level of gamma-hydroxybutyrate (GHB), which in SSADH-deficient mammals accounts for phenotypic abnormalities. Moreover, the level of GHB in Arabidopsis is light dependent.

Influence of transmetatarsal amputation in patients requiring lower extremity distal revascularization.

When a transmetatarsal amputation (TMA) is required, successful long-term limb salvage is questioned. We evaluated the influence of TMA on limb salvage in patients undergoing lower extremity revascularization. Patients who had distal bypasses extending to the infrapopliteal arterial tree and adjunctive TMA were retrospectively reviewed.

Renal revascularization in Takayasu arteritis-induced renal artery stenosis.

Purpose: This study was undertaken to define the long-term effects of renal revascularization on blood pressure, and renal and cardiac function in patients with Takayasu arteritis-induced renal artery stenosis (TARAS).

Methods: Twenty-seven patients (25 women; mean age, 27 years) with TARAS underwent intervention. Primary, primary assisted, and secondary patency rates were determined, and the late effects on blood pressure, renal and cardiac function, and survival were analyzed.

Papillary adenocarcinoma in a thymic cyst: a pitfall of thoracoscopic excision.

Carcinoma arising in a thymic cyst is very rare. We performed thoracoscopic subtotal resection of an assumed benign cyst. The patient had a reoperation when the diagnosis of papillary adenocarcinoma was established.

[Esophagectomy--who and where?].

Esophageal resection is a major operation, requiring a high level of surgical skill, experience and knowledge of the anatomy of the thorax, neck and abdomen. The immediate and late results of this operation vary considerably. This article reviews the world literature, attempting to examine whether there is a need to establish guidelines restricting the performance of esophageal resection to a limited number of medical centers.

The sequence of vessel interruption during lobectomy for non-small cell lung cancer: is it indeed important?

Objective: During pulmonary resections for non-small cell lung cancer, the pulmonary vein is traditionally interrupted first to prevent seeding of malignant cells and consequently decrease metastatic implantation. This hypothesis was never confirmed scientifically. The aim of the present study was to determine whether the sequence of vessel interruption during lobectomy (lobar vein or lobar artery first) affects disease recurrence.
