11/98. cytomegalovirus hemorrhagic gastritis.A 36-year-old male with acquired immune deficiency syndrome (AIDS) presented with intractable nausea and vomiting of 1 week's duration that was not attributable to his medications. An esophagogastroduodenoscopy showed hemorrhagic and necrotic gastric mucosa but no ulcers were found. Histopathology revealed viral inclusions consistent with cytomegalovirus (CMV) disease of the stomach. The patient received 6 weeks of intravenous ganciclovir with resolution of symptoms and endoscopic findings. Cytomegaloviral involvement of the stomach is rare, even in immunocompromised patients. Characteristic findings on upper endoscopy are punched-out gastric ulcers. This is a rare case of CMV disease of the stomach presenting as hemorrhagic, necrotic gastritis with inflammatory bridging.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
12/98. No neurological involvement for more than 40 years in klippel-feil syndrome with severe hypermobility of the upper cervical spine.We report the case of a 42-year-old woman with klippel-feil syndrome, who showed severe hypermobility of the upper cervical spine without neurological involvement for more than 40 years. Radiographs revealed the presence of the odontoid bone and fusion of the atlas, odontoid bone, and occiput. Congenital fusion was present from the axis to C5 as a block vertebra. Lateral flexion-extension radiographs revealed severe hypermobility at the junction between the odontoid bone and the axis. Prophylactic surgical stabilization has been recommended in patients with severe hypermobility, but adjacent disc problems may possibly occur at the unfused levels in the future. We believe that early prophylactic stabilization should not be indicated for klippel-feil syndrome without neurological involvement only because of hypermobility.- - - - - - - - - - ranking = 5keywords = upper (Clic here for more details about this article) |
13/98. gallbladder vasculitis associated with type-1 cryoglobulinemia.A patient with type I cryoglobulinemia and monoclonal gammopathy of uncertain significance was found to have acute gallbladder vasculitis. The most prominent manifestation was upper abdominal pain in the setting of normal liver tests. An abdominal ultrasound demonstrated a thickened gallbladder wall, along with gallstones. HIDA scanning showed a nonfunctioning gallbladder with an edematous and thickened wall. There was characteristic leukocytoclastic vasculitis affecting the gallbladder. The patient recovered uneventfully subsequent to cholecystectomy. gallbladder vasculitis should be considered in patients with unexplained upper abdominal pain and systemic vasculitis.- - - - - - - - - - ranking = 600.86462257079keywords = abdominal pain, upper (Clic here for more details about this article) |
14/98. Idiopathic "benign" intracranial hypertension: case series and review.Idiopathic "benign" intracranial hypertension is an uncommon but important cause of headache that can lead to visual loss. This study was undertaken to review our experience in the diagnosis and management of idiopathic intracranial hypertension, giving special attention to treatments used. A retrospective chart review was conducted on 32 patients diagnosed with idiopathic intracranial hypertension between 1984 and 1995. Subjects included 23 females and ranged in age from 2 to 17.5 years. headache was the most common symptom, followed by nausea and vomiting, double vision, and visual loss. papilledema was the most common sign. Others were VIth cranial nerve palsy and compromised visual acuity at or within 3 months of presentation. Management included administration of acetazolamide or corticosteroids, lumboperitoneal shunt, optic nerve fenestration, and repeat lumbar puncture. Treatment combinations were used in 40% of cases. During follow-up, headache, papilledema, and decreased visual acuity persisted for longer than 10 months in a significant number of patients. We conclude that idiopathic intracranial hypertension causes significant short- and long-term morbidity with no proven effective treatment available. A prospective study is needed to establish the indications for treatment and the efficacy of the treatments used.- - - - - - - - - - ranking = 256.17798169543keywords = headache (Clic here for more details about this article) |
15/98. death due to bioterrorism-related inhalational anthrax: report of 2 patients.On October 9, 2001, a letter containing anthrax spores was mailed from new jersey to washington, DC. The letter was processed at a major postal facility in washington, DC, and opened in the Senate's Hart Office Building on October 15. Between October 19 and October 26, there were 5 cases of inhalational anthrax among postal workers who were employed at that major facility or who handled bulk mail originating from that facility. The cases of 2 postal workers who died of inhalational anthrax are reported here. Both patients had nonspecific prodromal illnesses. One patient developed predominantly gastrointestinal symptoms, including nausea, vomiting, and abdominal pain. The other patient had a "flulike" illness associated with myalgias and malaise. Both patients ultimately developed dyspnea, retrosternal chest pressure, and respiratory failure requiring mechanical ventilation. leukocytosis and hemoconcentration were noted in both cases prior to death. Both patients had evidence of mediastinitis and extensive pulmonary infiltrates late in their course of illness. The durations of illness were 7 days and 5 days from onset of symptoms to death; both patients died within 24 hours of hospitalization. Without a clinician's high index of suspicion, the diagnosis of inhalational anthrax is difficult during nonspecific prodromal illness. Clinicians have an urgent need for prompt communication of vital epidemiologic information that could focus their diagnostic evaluation. Rapid diagnostic assays to distinguish more common infectious processes from agents of bioterrorism also could improve management strategies.- - - - - - - - - - ranking = 299.70725488887keywords = abdominal pain, chest (Clic here for more details about this article) |
16/98. Supratentorial leptomeningeal metastasis of a medulloblastoma without cerebellar tumor recurrence.The authors report on a 15-year-old girl presenting with headache and nausea. Cranial magnetic resonance imaging (MRI) showed a diffuse leptomeningeal contrast enhancement 5 years after resection of a posterior fossa medulloblastoma followed by radio- and chemotherapy. A left frontal biopsy revealed tumor spread. Histopathological findings of the tumor were identical to those obtained from the original medulloblastoma. To the authors' knowledge this is the first report of late supratentorial leptomeningeal metastasis from a medulloblastoma while no local recurrence or spinal leptomeningeal dissemination had occurred.- - - - - - - - - - ranking = 128.08899084772keywords = headache (Clic here for more details about this article) |
17/98. The iowa follow-up of chemically sensitive persons.Clinical symptoms and self-reported health status in persons reporting multiple chemical sensitivities (MCS) are presented from a 9-year follow-up study. Eighteen (69%) subjects from a sample of 26 persons originally interviewed in 1988 were followed up in 1997 and given structured interviews and self-report questionnaires. In terms of psychiatric diagnosis, 15 (83%) met DSM-IV criteria for a lifetime mood disorder, 10 (56%) for a lifetime anxiety disorder, and 10 (56%) for a lifetime somatoform disorder. Seven (39%) of subjects met criteria for a personality disorder using the personality Diagnostic Questionnaire-IV. Self-report data from the illness behavior Questionnaire and Symptom checklist-90-Revised show little change from 1988. The 10 most frequent complaints attributed to MCS were headache, memory loss, forgetfulness, sore throat, joint aches, trouble thinking, shortness of breath, back pain, muscle aches, and nausea. Global assessment showed that 2 (11%) had "remitted", 8 (45%) were "much" or "very much" improved, 6 (33%) were "improved", and 2 (11%) were "unchanged/worse". Mean scores on the SF-36 health survey showed that, compared to U.S. population means, subjects reported worse physical functioning, more bodily pain, worse general health, worse social functioning, and more emotional-role impairment; self-reported mental health was better than the U.S. population mean. All subjects maintained a belief that they had MCS; 16 (89%) acknowledged that the diagnosis was controversial. It is concluded that the subjects remain strongly committed to their diagnosis of MCS. Most have improved since their original interview, but many remain symptomatic and continue to report ongoing lifestyle changes.- - - - - - - - - - ranking = 128.4248637816keywords = headache, back (Clic here for more details about this article) |
18/98. The evolution of lemierre syndrome: report of 2 cases and review of the literature.lemierre syndrome (postanginal septicemia) is caused by an acute oropharyngeal infection with secondary septic thrombophlebitis of the internal jugular vein and frequent metastatic infections. A high degree of clinical suspicion is necessary for diagnosis. fusobacterium necrophorum is the usual etiologic agent. The disease progresses in several steps. The first stage is the primary infection, which is usually a pharyngitis (87.1% of cases). This is followed by local invasion of the lateral pharyngeal space and IJV septic thrombophlebitis (documented in 71.5% of cases), and finally, the occurrence of metastatic complications (present in 90% of cases at the time of diagnosis). A sore throat is the most common symptom during the primary infection (82.5% of cases). During invasion of the lateral pharyngeal space and IJV septic thrombophlebitis, a swollen and/or tender neck is the most common finding (52.2% of patients) and should be considered a red flag in patients with current or recent pharyngitis. The most common site of metastatic infection is the lungs (79.8% of cases). In contrast to the preantibiotic era, cavitating pneumonia and septic arthritis are now uncommon. Most patients (82.5%) had fever at some stage during the course of the disease. Gastrointestinal complaints such as abdominal pain, nausea, and vomiting were common (49.5% of cases). An elevated white blood cell count occurred in 75.2% of cases. hyperbilirubinemia with slight elevation of liver enzyme levels occurred in one-third of patients, but frank jaundice was uncommon, in contrast to its high frequency reported in the preantibiotic era. We conclude that, most likely as a consequence of widespread antibiotic use for pharyngeal infections, the typical course of the disease has changed since Lemierre's original description. The typical triad in our series was: pharyngitis, a tender/swollen neck, and noncavitating pulmonary infiltrates. The previous classical description of severe sepsis with cavitating pneumonia and septic arthritis was not commonly seen in our review. mortality was low in our series (6.4%), but significant morbidity occurred, which was likely preventable by early diagnosis and treatment. The pathophysiology, natural history, diagnostic methods for internal jugular vein thrombosis, and management are discussed.- - - - - - - - - - ranking = 299.4323112854keywords = abdominal pain (Clic here for more details about this article) |
19/98. superior mesenteric artery syndrome following surgery for scoliosis.STUDY DESIGN: A retrospective report of three cases outlining upper intestinal obstruction as a rare complication following surgery for scoliosis. OBJECTIVE: To present the clinical features, progression, and management of duodenal obstruction due to superior mesenteric artery compression after surgical treatment of scoliosis. SUMMARY OF BACKGROUND DATA: Superior mesenteric artery or cast syndrome has been reported historically in the literature. Many causes are described, among which is the complication of the surgical and nonoperative treatment of scoliosis. methods: Three adolescent patients were investigated for nausea and vomiting following surgical correction of scoliosis. RESULTS: Contrast radiography confirmed extrinsic obstruction of the third part of the duodenum by the superior mesenteric artery in all three patients. They were jointly managed with the gastrointestinal surgeons. Two patients recovered with conservative treatments, but the third required operative intervention with a laparotomy. CONCLUSIONS: vomiting following surgery for scoliosis should be investigated thoroughly, as superior mesenteric artery syndrome carries significant morbidity, protracted hospital stay, and potential mortality.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
20/98. Migraine-type headaches in children receiving chemotherapy and ondansetron.Six children developed severe daily migraine-type headaches during cancer treatment. In addition to chemotherapy drugs, all received daily doses of ondansetron, a 5-hydroxytryptamine type 3 receptor antagonist. 5-Hydroxytryptamine is considered to play a central role in migraine pathogenesis, and ondansetron may have caused headaches by producing 5-hydroxytryptamine dysfunction in the brain. All six children had either a personal or a family history of migraine, and this may be a risk factor for developing ondansetron-associated migraine-type headaches. ondansetron-induced headaches respond to withholding the drug and to standard antimigraine medications, but further study of a larger group of patients is required to confirm this impression.- - - - - - - - - - ranking = 1024.7119267817keywords = headache (Clic here for more details about this article) |
