1/1135. Old and new infarction of an epiploic appendage: ultrasound mimicry of appendicitis.

    Epiploic appendagitis is a self-limiting disease. Depending on its location, it may simulate nearly any acute abdominal condition. The ultrasound and computed tomographic (CT) features are characteristic, enabling ready diagnosis and thus preventing an unnecessary laparotomy. We describe a patient with acute abdominal pain in the right lower quadrant, in whom the combination of an old and fresh infarction of an epiploic appendage simulated appendicitis on ultrasound. Subsequent CT examination made the correct diagnosis. ( info)

2/1135. Acute torsion of the renal transplant after combined kidney-pancreas transplant.

    BACKGROUND: Surgical complications after combined kidney and pancreas transplantation are a major source of morbidity and mortality. Complications related to the pancreas occur with greater frequency as compared to renal complications. The occurrence in our practice of two cases of renal infarction resulting from torsion about the vascular pedicle led to our retrospective review of similar vascular complications after combined kidney and pancreas transplantation. methods: charts were reviewed retrospectively, and two patients were identified who experienced torsion about the vascular pedicle of an intra-abdominally placed renal allograft. RESULTS: Two patients who had received combined intraperitoneal kidney and pancreas transplantation presented at 16 and 11 months after transplant, respectively, with abdominal pain and decreased urine output. One patient had radiological documentation of abnormal rotation before the graft loss; unfortunately, the significance of this finding was missed. diagnosis was made in both patients at laparotomy, where the kidneys were infarcted secondary to torsion of the vascular pedicle. Both patients underwent transplant nephrectomy and subsequently received a successful second cadaveric renal transplant. CONCLUSIONS: The mechanism of this complication is a result of the intra-abdominal placement of the kidney, length of the vascular pedicle, excess ureteral length, and paucity of adhesions secondary to steroid administration. These factors contribute to abnormal mobility of the kidney. Technical modifications such as minimizing excess ureteral length and nephropexy may help to avoid this complication. ( info)

3/1135. Bone infarction complicated by sarcomatous change: a case report.

    A patient with a sarcoma of the tibia associated with multiple bone infarcts and a history of alcoholism, is presented. This is a rare association. The possible aetiological role of bone infarcts in relation to the development of a sarcoma is discussed. ( info)

4/1135. Late massive haemoptyses from bronchopulmonary collaterals in infarcted segments following pulmonary embolism.

    Massive, recurrent haemoptyses requiring blood transfusions occurred in a patient who had been diagnosed as having pulmonary thromboembolism 3 months earlier. To the authors' knowledge this is the first case report of this kind, in which massive haemoptyses were proved to be caused by large bronchopulmonary collaterals that had developed in the infarcted lung segments affected by embolism. Selective embolization of the collaterals proved to be therapeutic and life saving. ( info)

5/1135. Lessons to be learned: a case study approach--a case of temporal arteritis.

    A 71-year-old male presented with a history of sudden partial visual loss in the right eye with an inferior visual field defect over the past 3-4 days. He had no history of headache or of facial pain. Clinical examination confirmed that vision on the right side was reduced to 6/18 and on the left to 6/12. The right eye showed a relative afferent pupillary defect. There was no other abnormality of the anterior segment of either eye. The right retina showed a pale swollen optic disc and a provisional diagnosis of anterior ischaemic optic neuropathy (AION) was made. An urgent erythrocyte sedimentation rate (ESR) was ordered and the patient was asked to return to the eye clinic in one month. However, 16 days later--when it was first recognised that his ESR was elevated to 75 mm in the first hour--the patient was recalled immediately in order to commence systemic steroid treatment; but regrettably, by this time, his right eye had become totally blind. In this case, although the attending doctor made a correct clinical diagnosis on presentation, he failed to act upon the result of the blood test. ( info)

6/1135. Total gastric replacement following gas bloat in a 21-month-old child.

    A 21-month-old child with a previously repaired left congenital diaphragmatic hernia underwent a 360 degrees 'loose-wrap' Nissen fundoplication for gastroesophageal reflux. Failure to replace the dislodged nasogastric tube on the 2nd night led to severe gas bloat and total gastric infarction. A 30-cm retrocolic, N-shaped, isoperistaltic jejunal pouch was constructed for gastric replacement. A pyloromyotomy ensured free emptying and a pouchostomy secured the pouch to the abdominal wall. At 8 months all nutrition was oral except for a biannual vitamin B12 injection, there was no dumping, and the pouchostomy was removed. By 18 months growth, originally along the 10th centile, was sustained at the 50th centile. Our early impression recommends a 30-cm retrocolic, isoperistaltic, N-shaped jejunal pouch similar to that of Hays and Clark as a safe and effective replacement for the stomach in children. ( info)

7/1135. cluster headache-like attack as an opening symptom of a unilateral infarction of the cervical cord: persistent anaesthesia and dysaesthesia to cold stimuli.

    A 54 year old man experienced excruciating left retro-orbital pain with lacrimation and redness of the eye representative of a cluster headache attack. This was followed by left hemiparesis with plegia of the lower limb and left Horner's syndrome. Five days later the hemiparesis recovered while the patient developed hypoanaesthesia to cold stimuli that evoked painful burning dysaesthesia on the right side below the C4 level. MRI disclosed a discrete infarct in the left lateral aspect of the cord at C2 level concomitant to a left vertebral artery thrombosis. This limited infarct and the clinical symptoms suggest a hypoperfusion in the peripheral arterial system of the left hemicord, supplied both by the anterior and posterior spinal arteries. cluster headache-like attack and persistent dysaesthesia to cold stimuli are discussed respectively in view of the central sympathetic involvement and partial spinothalamic system dysfunction.

8/1135. Anemic infarction of the liver resulting from hepatic and portal vein thrombosis.

    True anemic infarction of the liver is a rare lesion. Most of the reported cases are due to occlusion of the hepatic artery. Whether venous occlusion can result in such anemic infarcts has been disputed although few authentic cases have been reported. A case of polycytheia vera complicated by hepatic and portal vein thrombosis with anemic infarction of a large segment of the liver is presented. The case illustrates that anemic infarcts of the liver can result from venous occlusion. The intense congestion secondary to hepatic vein occlusion may cause secondary arterial hypoperfusion unless the portal vein is available as an outflow tract. ( info)

9/1135. sickle cell trait and acute intermittent porphyria leading to small bowel infarction.

    sickle cell trait patients rarely have crises. A case of co-morbidity with acute intermittent porphyria is described in which trans-mural infarction of the distal ileum secondary to red cell sickling resulted in a fatal outcome. ( info)

10/1135. Nonocclusive small bowel infarction in familial dysautonomia syndrome.

    The authors report a case of a 14-year-old boy with familial dysautonomia (FD) in whom a small-bowel infarction developed during a dysautonomic crisis. Atypical features of the presentation included hypotension with prolonged fever and abdominal distension. The authors postulate that the bowel infarction was caused by prolonged hypoperfusion. It is recognized that the small bowel in normal subjects can adapt to periods of ischemia without irreversible injury. The authors speculate that the known abnormal systemic cardiovascular regulation in patients with FD may adversely affect splanchnic blood flow, which led to the catastrophic consequences in this case. This report draws attention to the risk of significant ischemic complications during a dysautonomic crisis, especially in the face of atypical features, and emphasizes the challenging cardiovascular management of such patients.
