PURPOSE This study evaluated the feasibility of a laparoscopic approach in children with generalized peritonitis secondary to perforated appendicitis. MATERIALS AND METHODS We retrospectively analyzed the medical records of patients who underwent laparoscopic appendectomy with drainage for generalized peritonitis secondary to perforated appendicitis at our hospital between September 2001 and ...

While animal studies indicate that controlled mechanical ventilation (MV) induces diaphragm weakness and myofiber atrophy, there are no data in humans that confirm MV per se produces diaphragm weakness. Whether or not diaphragm weakness results from MV, sepsis, corticosteroids, hyperglycemia, or a combination of these factors, however, is not the most important issue raised by the recent study ...

In view of the fact that right-sided hernia of the diaphragm is relatively infrequent, a report on the following case, observed in our Cinic, is of interest. In a series of 276 cases collected by Lacher, only I5 per cent of the total number of diaphragmatic hernias occurred on the right side. The reason seems quite obvious; the bulk of the liver, occupying the right dome of the diaphragm, preve...

BACKGROUND The physiological basis underlying the decline in the incidence of sudden infant death syndrome (SIDS) associated with changing the sleep position from prone to supine remains unknown. AIMS To evaluate diaphragm thickness (t(di)) and shortening in healthy term infants in the prone and supine positions in order to determine whether changes in body position would affect diaphragm res...

INTRODUCTION Pressure-support ventilation, is widely used in critically ill patients; however, the relative contribution of patient's effort during assisted breathing is difficult to measure in clinical conditions. Aim of the present study was to evaluate the performance of ultrasonographic indices of diaphragm contractile activity (respiratory excursion and thickening) in comparison to traditi...

PURPOSE This study aimed to determine whether routine urinalysis may serve as a tool in discriminating between acute appendicitis and perforated appendicitis in children. BASIC PROCEDURES We prospectively collected 357 patients with clinically suspected acute appendicitis. Urinalysis was performed in patients with clinically suspected acute appendicitis before surgical intervention. Routine u...

PURPOSE Perforations are rare but serious complications of colorectal cancer, with mortality rates of 30 to 40 percent. The aim of this retrospective study was to investigate possible indicators of prognosis and causes of death and to evaluate the risk of this complication by comparing results in perforated tumors with uncomplicated cancers or large-bowel perforations attributable to benign cau...

Most models for predicting the acoustic response of perforated panels are based on the assumption that there is no interaction between the holes. The common way of taking into account the perforates effects is the use of Fok's functions. The few papers that deal with these effects study the case of low sound pressure levels. This paper investigates the Holes Interaction Effects (HIE) of perfora...

We present a methodology for the computation of flow fields involving complex perforated surfaces in propulsion applications. Of particular interest is the treatment of perforated flaps used as wedge-shaped fan flow deflectors for reducing jet noise of a supersonic turbofan engine. A three-dimensional Reynolds-Averaged Navier-Stokes solver is used to compute the flow field of the external jet p...

INTRODUCTION Duodenal perforation is one of the common pathologies in patients presenting in emergency with acute abdominal pain in an emergency ward and requires prompt surgery as life saving and curative intervention. The present study was conducted to determine whether the minimal access approach by laparoscopy was equally feasible as the open method. AIM To compare laparoscopic vs. open m...
