Abdominal pain in patients with acquired immune deficiency syndrome.

The patient with acquired immune deficiency syndrome (AIDS) and abdominal pain presents the surgeon with a difficult challenge. The pain may be due to an opportunistic infection, ileus, organomegaly, or a true surgical emergency. The hospital records of 235 patients with AIDS were reviewed. Of the 29 patients with abdominal pain, 12 had infectious diarrhea, eight were diagnosed as having ileus or organomegaly, and nine had miscellaneous causes for their pain. Only five patients underwent laparotomy. Two patients were operated on for pain associated with bleeding (Meckel's diverticulum and intestinal Kaposi's sarcoma); one had a perforated duodenal ulcer and one had severe ileitis. One patient was electively operated on for Burkitt's lymphoma. Laparotomy for abdominal pain is not usually necessary in patients with AIDS. Specific recommendations for evaluation and management of these patients are offered.

Indications for intubation in blunt chest trauma.

The value of endotracheal intubation and internal stabilization in severe chest injuries is well known. Recent reports have proposed that many such patients can be managed without intubation. To determine which patients need intubation we reviewed 140 patients with three or more rib fractures who presented to our hospitals from 1 January 1979 through 31 December 1983: 119 nonintubated patients (Group A); 13 patients intubated on admission (Group B); five patients intubated after hospital day 1 (Group C); and three patients intubated questionably on admission (Group D). The purpose of this report was to identify the factors which indicated severe pulmonary injury necessitating intubation. The need for intubation was correlated with five risk factors: 1) initial respiratory rate of over 25 min; 2) pulse greater than 100 min; 3) systolic blood pressure less than 100 mm Hg; 4) poor initial arterial blood gas; 5) the presence of other injuries. There was no correlation between severity of pulmonary injury and number of fractures, bilateral and/or segmental fractures, flail chest, contusion of lung, or age of patient. There was a greater percentage of complications and deaths in intubated patients (Groups B, C, and D). Group C patients all had poor initial blood gases and were erroneously not intubated early, even though 60% of them had three or more risk factors, as did Group B patients. Only 4% of patients who did not need intubation (Group A) had three or more risk factors. Group D patients were intubated without apparent indication. They had good initial blood gas levels and only one risk factor.(ABSTRACT TRUNCATED AT 250 WORDS)

Management of foreign bodies and trauma of the rectum.

A series of 101 patients with trauma of the rectum, secondary to homosexual practices, presenting at this hospital and medical center is reviewed. Two patients were injured twice. Thirty-six patients had retained foreign bodies in the rectum, 55 had lacerations of the mucosa, two had disruptions of the anal sphincter and ten had perforations of the rectosigmoid. The majority of retained foreign bodies can be removed on an outpatient basis. If removal is not immediately possible, the patient should be admitted for observation and removal of the foreign body transanally under anesthesia. Routine sigmoidoscopic examination is performed after removal. Removal seldom requires laparotomy. Simple nonbleeding lacerations of the mucosa can be managed on an outpatient basis. Patients with abdominal pain, fever, continued bleeding, large lacerations or tear of the sphincter should be admitted and observed or operated upon, or both, as needed. Serious injuries, secondary to homosexual acts, can and do occur, as evidenced by the mortality reported in this series. Perforations of the rectosigmoid above the peritoneal reflection can be treated by laparotomy, repair of the perforation, removal of gross contamination by irrigation, proximal loop colostomy and appropriate antibiotic therapy. Perforations below the peritoneal reflection are challenging instances which require individualized management.

Perforations and foreign bodies of the rectum: report of 28 cases.

A series comprised of 28 patients (five with perforations of the recto-sigmoid colon and 23 with lodged rectal foreign bodies) is presented. The symptomatology, physical, laboratory and x-ray findings are described. Methods of management are discussed, with emphasis on the operative management of perforations and the conservative approach to retained foreign bodies. It is felt that these protocols will be useful to physicians who see this practice less frequently. X-rays of two more unusual cases are depicted. A thorough review of the literature is also presented. This is the largest reported series of patients with retained rectal foreign bodies and/or perforations. The series includes two female patients, a heretofore unreported occurrence.

A simple method of repositioning the wayward central venous catheter.

Malposition of a central venous catheter occurs despite improvements in catheter design and regardless of the skill of the physician. A simple method of repositioning a central venous catheter has been successful in 25 of 25 attempts. Documentation of the rationale for the use of this technique is provided using x-rays.

A study of urban bicycling accidents.

This study was undertaken because of the large number of bicycle accident victims treated in our emergency room. Its aim was to assess the type, frequency, and mechanism of occurrence of bicycle accidents as well as characterization of the type of injuries sustained and the expense incurred by such accidents. One hundred seventy-two patients injured over a 10 month period were studied. The upper extremity was found to be particularly at risk of injury. Fractures accounted for 20% of all injuries. The most common accident mechanisms were being struck by a motor vehicle, falling from a bicycle, or being struck by a bicycle. Eleven percent of the patients studied were pedestrians. Increasing pedestrian-cyclist awareness and modification of currently used protective gloves are proposed to prevent injuries associated with urban cycling.
