BACKGROUND AND OBJECTIVES Postoperative pneumoperitoneum following laparoscopic surgery is self-limited, typically resolving within days. METHODS We analyzed the case of a 48-y-old woman who presented with acute abdominal pain 48 d after a total laparoscopic hysterectomy. Imaging studies revealed free air under the diaphragm suggesting a perforated viscus. RESULTS An exploratory laparotomy ...

A 75-year-old woman with a past medical history of hypertension, presented to the emergency department (ED) with 12 h of persistent, non-radiating, diffuse abdominal pain. The patient had undergone a colonoscopy the day before. A chest X-ray study was done in the ED after the patient was sitting upright for at least 10 min, but shows no free air under the diaphragm (Fig. 1). The abdominal X-ray...

In this paper the effect of corrugated diaphragm on performance of MEMS microphone is described. The corrugated diaphragm is modeled in order to improve the sensitivity of micromachined silicon acoustic sensor. Analytical analyzes have been carried out to derive mathematic expressions for the mechanical sensitivity and displacement of corrugated diaphragm with residual stress. It is shown that ...

eventration of the diaphragm is a condition characterized by an attenuated but otherwise intact diaphragm. twenty patients (age range: 2 days to 11 years) were treated for eventration of the diaphragm during a ten year period (19 85-1995). there were 11 girls and 9 boys with a mean gestational age of 37 weeks. 14 patients were born with cephalic presentation, 3 patients with breech delivery and...

background: delay in diagnosis and treatment of perforated appendicitis may cause life-threatening complications. the aim of this study was to determine and compare pre-operative total and direct bilirubin levels in cases of simple and perforated acute appendicitis in order to improve the clinical decision making.   methods: this prospective observational study included eighty patients who unde...

introduction: diaphragmatic hernia could be caused by congenital disorders, blunt trauma or penetrating injuries. the diagnosis of traumatic diaphragmatic hernia is normally neglected during the first presentation leading to late complications and considerably increased mortality and morbidity among the patients. materials and methods: in this retrospective, descriptive study, we reviewed the m...

In this paper we present a new model for calculating the capacitance of MEMS sensor with corrugated diaphragm. In this work the effect of residual stress is considered on deflection of diaphragm and capacitance of sensor. First, a new analytical analyzes have been carried out to derive mathematic expressions for central deflection of corrugated diaphragm and its relationship with residual stres...

Case Report In 1943 Mr. G. A. S. had an antecolic valved Hofmeister partial gastrectomy performed for a high posterior wall gastric ulcer. The operation stood him in good stead for many years but after I 2 years he had an attack of epigastric pain lasting an hour and in the following year he suddenly got another attack after drinking one-and-a-half pints of beer. The pain lasted all night and i...
