Association of xerophthalmia, flecked retina, and pseudotumor cerebri caused by hypovitaminosis A

PURPOSE: To report an unusual case of hypovitaminosis A with bilateral papilledema and flecked retina that regressed after restoration of vitamin A deficiency. METHOD: Case report. A 27-year-old woman had undergone a biliopancreatic bypass for obesity in 1990. In 1995, she presented with bilateral xerophthalmia, bilateral papilledema, and bilateral flecked retina. RESULTS: Laboratory tests demonstrated low serum levels of vitamin A (0.8 micromol/l) and vitamin E (8.54 micromol/l). Xerophthalmia, papilledema, and flecked retina disappeared after restoration of normal vitamin A blood levels. CONCLUSION: Hypovitaminosis A after biliopancreatic bypass for obesity may be associated with xerophthalmia, pseudotumor cerebri, and flecked retina.     

Perforated duodenal diverticulum caused by enterolith

OBJECTIVES: To describe a community outbreak of methicillin-resistant Staphylococcus aureus (MRSA) and to investigate risk factors for MRSA transmission and infection in a wrestling team. DESIGN: Case series and retrospective cohort study. SETTING: A high school wrestling team and the surrounding community in southern Vermont, 1993 to 1994. PATIENTS OR OTHER PARTICIPANTS: The case series included persons whose MRSA-positive infections were identified at a hospital laboratory from January 1, 1993, through February 28, 1994, and a health maintenance organization laboratory from July 1, 1993, through February 28, 1994. A wrestling team case-patient was a 1993-1994 team member with an MRSA-positive culture during the period from January 1, 1993, through February 28, 1994. INTERVENTIONS: Visual inspection of wrestlers before matches was instituted. Affected wrestlers were excluded from wrestling and advised to seek appropriate medical care. Heightened attention was given to personal and environmental hygiene. MAIN OUTCOME MEASURES: Colonization or infection with MRSA. RESULTS: Seven of 32 team members were MRSA positive (6 infected, 1 colonized). All lesion-positive wrestlers were tested by pulsed field gel electrophoresis and found to be infected with the same MRSA strain, as were 6 nonwrestlers. No risk factors for MRSA infection were identified. CONCLUSIONS: The MRSA was transmitted among members of a wrestling team. Infection with MRSA should be suspected in outbreaks of boils that are nonresponsive to standard antibiotic therapy among healthy participants of contact sports and their close contacts.     

A case of Lyell's syndrome caused by carbamazepine

A case is described of Lyell syndrome in a female patient with schizoaffective psychosis which developed several days after addition of carbamazepine to the psychotropic treatment used. After withdrawal of the drug and three weeks of treatment with prednisone in dose 60 mg daily, antibiotic therapy and intensive dermatological-nursing care, full remission of skin lesions and oral mucosa lesions was obtained.     

A case of spontaneous peritonitis caused by Weeksella virosa

A case of spontaneous peritonitis caused by Weeksella virosa is reported. This Flavobacterium has never been reported as a cause of spontaneous bacterial peritonitis. The patient responded to antimicrobial therapy. Clinical and therapeutic implications are discussed.     

A case of obstructive colitis caused by possible colostomy dysfunction

A case of obstructive colitis caused by possible stricture of colostomy is herein reported. A 58 year old female with an obstructive sigmoid colon cancer underwent an emergency descending decompression colostomy. At laparotomy, the colon proximal to the carcinoma was markedly distended and the bowel wall was thin, but the serosa appeared normal. Postoperatively, however, abdominal pain and distension persisted and low grade fever developed. Diarrhea through the colostomy continued. Nine days after the initial surgery, she underwent a left hemicolectomy. An abnormally thickened segment was identified in the resected specimen; normal mucosa was lost and several pseudopolyps were scattered. Histopathological findings of the abnormal segment were consistent with obstructive colitis. A preserved segment of normal mucosa intervened between the site of colostomy and the abnormal segment of obstructive colitis. A possible stenosis of the colostomy was considered to have caused colostomy dysfunction and subsequent obstructive colitis. She was complicated with anastomotic leakage due to the diseased colon being used for anastomosis. Obstructive colitis should be kept in mind in patients with obstructive colonic carcinomas who complain of persistent abdominal pain, distension and diarrhea in the early postoperative period after colostomy.     

Bilateral orbital metastases from breast carcinoma. A case of false pseudotumor

OBJECTIVE: To inform clinicians of a metastatic orbital neoplasm that frequently masquerades as an orbital inflammatory syndrome and to stimulate thought regarding this neoplasm's fundamental pathobiology specific to its orbital involvement. DESIGN: Interventional case report and literature review. PARTICIPANTS: A 47-year-old woman with an acquired, bilateral, diffusely infiltrative orbital process is described. INTERVENTION: The clinical and radiographic features of the patient's orbital process are reported. The review of two prior fine-needle aspiration biopsy specimens failed to reveal a diagnosis. Histopathologic examination of an open surgical biopsy specimen included standard light microscopy of frozen and formaldehyde-fixed, paraffin-embedded tissue. RESULTS: Characteristics light microscopy findings suggested the diagnosis of metastatic lobular carcinoma of the breast. The patient refused all therapeutic intervention and died 9 months after orbitotomy. CONCLUSION: The presentation of breast carcinoma metastatic to the orbit as a bilateral infiltrative process is far more common than appreciated previously. Its rate of bilateral orbital involvement is 20%, whereas this rate for other adult neoplasms is much lower. The authors report an additional case, review the clinical features of previous case reports and series, and discuss aspects of the metastatic process. Breast carcinoma must be included in the differential diagnosis of infiltrative orbital processes encountered in adult female patients. When "orbital pseudotumor" is detected in an adult female patient, a thorough medical history must be obtained and physical examination performed. If a possible primary breast carcinoma is indicated, one must be wary of metastatic disease, and a histologic orbital diagnosis is warranted. The frequency of orbital metastasis and bilateral orbital involvement of this neoplasm reinforces the possibility for organ-specific metastases.     

Orbital pseudotumor: case report and overview

BACKGROUND: The most common cause of a sudden onset of painful proptosis with diplopia in an otherwise healthy adult is orbital pseudotumor. However, there are other conditions that mimic this presentation and must be ruled out with laboratory testing and imaging studies. CASE REPORT: A 41-year-old Hawaiian man sought treatment for an acute, progressive, painful, left ophthalmoplegia without exophthalmos. During the next week, a loss of accommodation and associated pupillary reaction, decreased visual acuity, color vision deficits, and a paracentral scotoma developed. CT and MRI revealed a mass in the orbital apex. All systemic findings were negative, and high-dose systemic steroid therapy was initiated. Symptoms resolved within hours of the first dose, and signs were completely absent 1 month later. Follow-up MRI revealed complete absence of the previously noted mass. CONCLUSION: This is an atypical case of orbital pseudotumor, since there was no exophthalmos. It was diagnosed by clinical presentation, laboratory and imaging studies, and response to therapy.     

A case of intermittent Wolff-Parkinson-White syndrome caused by high spinal anesthesia

We experienced a case of intermittent Wolff-Parkinson-White (WPW) syndrome following spinal anesthesia. This patient had neither any past history of cardiac symptoms nor any abnormal finding in the preoperative electrocardiogram. Soon after spinal anesthesia, the level of anesthesia spread to C6. Both abbreviated PR intervals and delta waves characteristic of WPW syndrome appeared on the electrocardiogram monitor. These abnormal wave-forms continued throughout the operation, but disappeared after three days. This case was diagnosed as intermittent WPW syndrome based upon these observations. High spinal anesthesia effectively blocks the cardiac sympathetic nerve and suppresses the normal atrioventricular conduction. Further, conduction by the accessory pathway is facilitated by the relative excitement of parasympathetic nerve. In the present case, the conduction by the accessory pathway, which had originally been very poor, was transiently promoted by the above-mentioned mechanism, and abnormal wave-forms characteristic of WPW syndrome appeared temporarily in the electrocardiogram.
