1/386. Wellens' syndrome.We describe a patient with Wellens' syndrome. In view of the large area of myocardium at risk, the importance of recognizing the significance of this ECG pattern is of critical importance for the emergency physician, especially those involved in the evaluation of patients at emergency department chest pain centers. Wellens' syndrome, the criteria for diagnosis, and a discussion of its implications are presented.- - - - - - - - - - ranking = 1keywords = chest pain, chest (Clic here for more details about this article) |
2/386. Functional intestinal obstruction due to deficiency of argyrophil neurones in the myenteric plexus. Familial syndrome presenting with short small bowel, malrotation, and pyloric hypertrophy.In 3 infants functional intestinal obstruction, associated with a short small intestine, malrotation, and pyloric hypertrophy, was shown to be due to failure of development of the argyrophil myenteric plexus, with the absence of ongoing peristalsis. 4 infants with similar clinical features have been described previously, and there is evidence for an autosomal recessive mode of inheritance of this syndrome.- - - - - - - - - - ranking = 0.49243673684704keywords = plexus (Clic here for more details about this article) |
3/386. Stress-induced SAPHO syndrome.We describe the case of a woman with the classic combination of features of synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome, including pustulosis palmo-plantaris and anterior chest wall involvement. The varying symptomology, etiology and pathogenesis of this syndrome and the contribution of stress are discussed. The authors ascribe the dearth of reported cases to lack of awareness and recognition of SAPHO, and not to the real incidence of the syndrome.- - - - - - - - - - ranking = 0.19997078452682keywords = chest (Clic here for more details about this article) |
4/386. Wrinkly skin syndrome: ultrastructural alterations of the elastic fibers.We report the clinical and pathologic features of a patient with wrinkly skin syndrome. The essential clinical features were wrinkly skin with poor elasticity over the abdomen and on the dorsum of the hands and feet, increased palmar and plantar creases, and a prominent venous pattern over the chest. On light microscopy, histopathologic findings included appreciable heterogeneity in the structure, amount, and distribution pattern of elastic fibers. agglutination and fragmentation of the microfibrillar component and a remarkable decrease in elastin were the major ultrastructural features. The differential diagnosis with other connective tissue disorders is discussed.- - - - - - - - - - ranking = 0.19997078452682keywords = chest (Clic here for more details about this article) |
5/386. Systemic sarcoidosis and cutaneous lymphoma: is the association fortuitous?The association of systemic sarcoidosis and malignant lymphoma is known as the 'sarcoidosis-lymphoma syndrome'. Cutaneous involvement is rare in this syndrome. We report a 52-year-old woman who was diagnosed as having tumour-stage mycosis fungoides. Complete remission was achieved by combination therapy consisting of isotretinoin, interferon (IFN) alpha, electron beam irradiation, photochemotherapy and topical corticosteroids. Three years later, the patient developed systemic sarcoidosis characterized by yellowish papules on the abdominal wall and the eyelids that histologically revealed non-caseating granulomas, multiple fine-nodular interstitial pulmonary infiltrates on chest X-ray, hilar lymphadenopathy, decreased vital capacity and increased lymphocyte count in bronchoalveloar lavage fluid. As opposed to most of the reported cases, in our patient the manifestation of cutaneous lymphoma preceded the diagnosis of systemic sarcoidosis. We review the cases reported in the literature and discuss a possible causal and temporal relationship as well as the role of IFN alpha in the development of sarcoidosis.- - - - - - - - - - ranking = 0.19997078452682keywords = chest (Clic here for more details about this article) |
6/386. Treatment of may-thurner syndrome with catheter-directed thrombolysis and stent placement, complicated by heparin-induced thrombocytopenia.may-thurner syndrome is an uncommon process in which the right common iliac artery compresses the left common iliac vein, resulting in left iliofemoral deep vein thrombosis and severe leg edema. We report the case of a 41-year-old female who presented with severe left leg edema present for 1 day. One week earlier she had experienced acute shortness of breath and pleuritic chest pain. Duplex ultrasound revealed a left iliofemoral deep vein thrombosis. A computed tomography (CT) scan performed for abdominal pain revealed thrombosis of the entire left common and external iliac veins. A ventilation-perfusion scan diagnosed a pulmonary embolism. The patient was treated with systemic intravenous heparin and catheter-directed thrombolysis of the iliofemoral deep vein thrombosis. Complete thrombolysis and iliofemoral vein patency was achieved over 5 days. A persistent stenosis in the left common iliac vein consistent with may-thurner syndrome was alleviated with percutaneous balloon angioplasty and placement of a Wallstent. heparin therapy was terminated at the time of stenting because of suspected heparin-induced thrombocytopenia. The patient was started on a continuous infusion of 10% dextran 40, and warfarin therapy was initiated. heparin-induced antibodies were confirmed by a C-14 serotonin release assay. The endovascular reconstruction remains patent 4 months later. heparin-induced thrombocytopenia complicating endovascular reconstruction of the iliofemoral venous system in a patient with may-thurner syndrome is an uncommon occurrence. This case and a review of the literature are discussed.- - - - - - - - - - ranking = 1keywords = chest pain, chest (Clic here for more details about this article) |
7/386. A case of vasospastic angina presenting Brugada-type ECG abnormalities.An electrophysiological study and a provocative test of coronary artery spasm was attempted in a 68-year-old man who was having syncopal attacks and chest pain. His electrocardiogram had the characteristics of brugada syndrome and ventricular fibrillation (VF) was induced by programmed electrical stimulation. ST-segment elevation became exaggerated by procainamide, which could not prevent the induction of VF. coronary angiography revealed no stenotic lesions, and spasm in the left coronary artery was induced by intracoronary administration of acetylcholine with similar chest pain to that experienced before. Under treatment with diltiazem and flecainide, which suppressed the induction of VF, the patient experienced no recurrence of symptoms despite persistent ST-segment elevation. No previous reports have described coronary spasm associated with Brugada-type ECG abnormalities, and patients with syncope should be evaluated carefully.- - - - - - - - - - ranking = 2keywords = chest pain, chest (Clic here for more details about this article) |
8/386. The use of patient-controlled boluses of local anaesthetic via a psoas sheath catheter in the management of malignant pain.patients who develop malignant infiltration of the psoas muscle and the lumbar plexus often experience a severe complex pain syndrome characterised by deep somatic pain, neuropathic pain and psoas spasm. Conventional analgesic regimes may not relieve these symptoms adequately. We describe the use of patient-controlled boluses of local anaesthetic via a psoas sheath catheter in this scenario. The recent availability of portable infusion pumps with the capability to deliver large volume boluses with long lockout times made this intervention possible and allowed the patient to be discharged home with effective relief of pain.- - - - - - - - - - ranking = 0.098487347369409keywords = plexus (Clic here for more details about this article) |
9/386. diagnosis of Chilaiditi's syndrome with abdominal ultrasound.Chilaiditi's sign is a radiographic term used when the hepatic flexure of the colon is seen interposed between the liver and right hemidiaphragm. When symptomatic, this is Chilaiditi's syndrome. We report a case of a 70-year-old man who presented with abdominal pain, vomiting, singultus and constipation. Ultrasound was initially performed which showed an intestinal loop between the anterior surface of the right liver lobe and the diaphragm. The chest X-ray revealed colon gas under the right diaphragma and the abdominal CT-scan confirmed the hepatodiaphragmatic interposition of the colon. Colonic elongation and laxity of colonic and hepatic suspensory ligaments are the principal predisposing factors. The advantages of the abdominal ultrasound in the diagnosis and follow-up as well as possible complications and forms of therapy with this syndrome are discussed.- - - - - - - - - - ranking = 0.19997078452682keywords = chest (Clic here for more details about this article) |
10/386. The double-crush phenomenon--an unusual presentation and literature review.The double-crush syndrome was initially described by Upton and McComas in 1973. They postulated that nonsymptomatic impairment of axoplasmic flow at more than one site along a nerve might summate to cause a symptomatic neuropathy. This was suggested by their clinical observation that the majority of their patients had a median or ulnar neuropathy associated with evidence of cervicothoracic root lesions. They also hypothesized that one of the constraints on axoplasmic flow could be a metabolic neuropathy, and this is supported by the high association of diabetes and carpal tunnel syndrome. Other researchers have since reported series of patients supporting the frequent association of a proximal and distal nerve compression syndrome, including carpal tunnel syndrome associated with cervical radiculopathy, brachial plexus compression, and diabetic neuropathy. Subsequently, MacKinnon and Dellon have expanded the description of this syndrome to include a) multiple anatomic regions along a peripheral nerve, b) multiple anatomic structures across a peripheral nerve within an anatomic region, c) superimposed on a neuropathy, and d) combinations of the above. We present an unusual case of symptomatic nerve compression caused by two nonanatomic structures within an anatomic region.- - - - - - - - - - ranking = 0.098487347369409keywords = plexus (Clic here for more details about this article) |
