Vaginal evisceration 1

Intestinal evisceration through the vagina is exceptionally rare. We report the cases of two patients presenting with this unusual clinical condition. Predisposing factors and management of vaginal evisceration are discussed.

Torsion of the fallopian tube

Isolated fallopian tube torsion is a rare entity that most frequently occurs during the menstruating years, but has also been reported in premenopausal and postmenopausal women. Diagnosis of this condition is often delayed because of the rarity of its occurrence and prolonged investigations to rule out more common causes of acute abdominal pain. A case of a 13-year-old girl with isolated left fallopian tube torsion is presented. A high index of suspicion must be maintained for adnexal torsion in women with abdominal pain so that an attempt can be made to salvage the adnexal structures.

Anabolic steroid use as the possible precipitant of dilated cardiomyopathy.

Anabolic-androgenic steroid (AAS) use is common among young males, including adolescents. There have been several anecdotal reports of severe cardiovascular events in self-reported young users of AAS, including acute myocardial infarction, sudden cardiac death, and cardiomyopathy. We present an additional case of a young male weight lifter who presented with dyspnea and chest pain attributable to dilated cardiomyopathy (DC), his only known risk factor being the recent use of AAS. The possible role of AAS in the development of DC is discussed.

Outcomes of anticoagulated trauma patients

Patients on warfarin are at high risk for potentially life-threatening hemorrhage even after relatively minor trauma. Outcomes of these patients and the potential complications of reversing the effects of anticoagulation have received little attention. This study was performed to determine the overall outcome of orally anticoagulated patients who sustained injury as well as to determine any untoward effects of reversing their anticoagulated states. A retrospective study of injured patients on warfarin was conducted on patients admitted to an urban, university, tertiary-referral, level I trauma center between 1/1/93 and 12/31/96. Surviving patients were followed for a period of at least 1 month. Injuries were grouped by anatomic site. Charts were reviewed for degree of anticoagulation on admission (ie, initial international normalized ratio [INR]), survival, adverse effects of reversal of anticoagulation, and reinstitution of warfarin therapy. Discharged patients were contacted at home for follow-up. Thirty-five consecutive patients, 18 men and 17 women, on warfarin therapy at the time of their injuries were reviewed. The mean age was 75 years, with a range of 39 to 96. The mean follow-up period was 12.7 months. Reasons for anticoagulation included atrial fibrillation, prosthetic heart valves, revascularized limb, hypercoagulable state, deep venous thrombosis, pulmonary embolism, phlebitis, and aortic stenosis. Mean admission INR was 3.2, with a range of 1.6 to 10.0. There were 8 in-hospital deaths. Intracranial hemorrhages accounted for the majority of injuries. Ten patients were not given reversal therapy. Four complications were attributable to reversal therapy (upper extremity hemiplegia, transient ischemic attack, deep venous thrombosis, arterial thrombosis). Twenty-one patients had their warfarin reinstituted. Follow-up of surviving patients ranged from 1.5 to 42 months. Patients on warfarin are at high risk for intracranial hemorrhage following trauma. Patients on warfarin may be reversed during the acute period following injury, but transient complications may arise. Further prospective studies need to be conducted to determine which anticoagulated trauma patients may not require reversal therapy.

Neonatal fever: Utility of the Rochester criteria in determining low risk for serious bacterial infections

The purpose of this study was to test the utility of the Rochester criteria in determining which febrile neonates are at low risk for serious bacterial infections (SBI). This was a retrospective study over a 5-year period of 134 patients younger than 29 days old with fever without a source evaluated in the emergency department. Results of urinalysis, lumbar puncture, peripheral white blood cell count, and cultures of blood, urine, cerebrospinal fluid, and stool were recorded. Of the 134 neonates, 71 were high-risk, 48 low-risk, and 15 were not classifiable by the available data. Nineteen of the 71 high-risk patients (26.8%) had SBI (2 patients had 2 SBI). Three of the 48 low-risk neonates (6.3%) had SBI (1 patient had 2 SBI). None of the 15 nonclassifiable patients had SBI. Employing the Rochester criteria to the fully cultured neonates who could be risk-stratified, the sensitivity, specificity, positive predictive value, and negative predictive value were 86.4%, 46.4%, 26.8%, and 93.8%, respectively. Although outpatient management of febrile neonates may be feasible, a small percentage of neonates meeting low-risk criteria will have a SBI.

Traumatic atlanto-occipital dislocation: A potentially survivable injury

Although survival with traumatic atlanto-occipital dislocation (AOD) is rare, there have been reports of victims who have sustained this injury with good neurological outcome. Plain lateral cervical spine radiography is the initial diagnostic procedure but may miss subtle dislocations. Several methods for the interpretation of the normal atlanto-occipital alignment have been devised and are discussed. Computed tomography (CT) and magnetic resonance imaging (MRI) are valuable studies in the diagnosis and management of AOD. Halo immobilization and posterior spinal fusion are the preferred modes of treatment. Vascular injury may contribute to the neurological deficits seen with AOD and is potentially reversible. Three cases are reported, two with survival of 1 day, and one long-term survivor with poor neurological outcome because of associated cerebral trauma.

Injury patterns with snowboarding

Snowboarding is a winter sport that has shown a considerable increase in popularity during the last 2 decades. As a result, there has been a continued rise in the number of visits to the emergency department (ED) for injuries sustained while snowboarding. Previous studies have concluded that those injured tend to be male, younger, and more inexperienced than their alpine skiing counterparts. This study examines the injury patterns seen in one ED during peak winter sport recreational months over a 5-year period. This retrospective review describes 71 patients with a broad spectrum of injury patterns, but reports a higher incidence of head and spinal injuries than previously documented. Furthermore, recommendations to prevent future injuries as well as education for first responders and physicians regarding the high likelihood of serious injury is discussed.

Good outcomes of open pelvic fractures

While pelvic fractures are common injuries, those which communicate with an open wound are much less commonly encountered. These injuries have been associated with high morbidity and mortality in previous studies. We investigated our experience with open pelvic fractures retrospectively over a 79-month period. A total of 17 patients were identified, representing 2.7% of all pelvic fractures seen during this time period. There were no fatalities among the 15 patients who were not in cardiac arrest on arrival. Associated injuries were present in all patients. Functional outcome was good in eight patients and fair in seven. Although open pelvic fractures are severe injuries, survival in our study was 100% in those not arriving in cardiac arrest.

Sternoclavicular joint injuries

Injuries to the sternoclavicular (SC) joint are infrequently encountered. However, retrosternal SC joint dislocations are potentially life-threatening injuries which must be recognized by the examining physician and treated as soon as possible. Plain radiography often fails to fully distinguish SC joint injuries, and computed tomography has emerged as the diagnostic modality of choice for defining the injury complex and surrounding injuries. We have encountered 6 cases of SC joint injuries over the past 3 years and describe their presentation and management.

Geriatric trauma: Outcomes of elderly patients discharged from the ED

This study was undertaken to investigate which patients 65 years of age or older have adverse outcomes after discharge from the emergency department (ED) after an injury. Patients were enrolled prospectively at an urban university center from September 15, 1996, until August 31, 1997. Patients sustaining any potentially serious form of injury were included. Data about comorbid conditions, preinjury medications, and types of injuries sustained were recorded. Patients were contacted at home at least 30 days after discharge and were questioned about their overall health, need for admission since ED discharge, and whether any complications developed. One hundred five consecutive patients were enrolled, but 5 patients were lost to follow-up. There were 74 low-mechanism falls (LMFs), 11 low-mechanism motor vehicle crashes (LMMVCs), 8 high-mechanism motor vehicle crashes (HMMVCs), 3 high-mechanism falls (HMFs), and 4 other types of injuries. Follow-up ranged from 30 to 147 days, with a mean of 49 days. On follow-up, 88 patients were doing well, 9 were fair, and 3 were doing poorly; of the latter, their poor health was unrelated to their injuries. Complications included 2 extremity infections and 1 poorly healing wound. Eleven patients were seen in an ED within the first 30 days after injury, 6 of whom for problems related to their initial injury or its management. These results show that there is a subset of elderly victims of trauma who may be safely discharged home after appropriate evaluation. Return visits to the ED were just as often related to comorbid conditions as to initial injury.
