Purpose: Our study describes ultrasonography (US) aspects of complications related to the use of the Bioenterics intragastric balloon (BIB) system for the treatment of moderate obesity., Materials and Methods: Over the last three years 151 BIBs were endoscopically placed and inflated with 500-600 ml of saline plus 10 ml of methylene blue in 131 patients (mean age 38.4 years, range 18-72; 46 males, 85 females, mean body mass index 43.8 kg/m(2)). In all cases abdominal US was carried out before and 1-2 days after endoscopy and thereafter at scheduled follow-up visits and/or whenever the patient complained of heartburn, vomiting, a sensation of ''absence of the BIB'' with or without staining of urine and/or faeces., Results: The BIB appeared as a round anechoic structure, with a thick hyperechoic wall and a hyperechoic band-like valve inside. In 8 cases staining of urine and/or faeces prompted immediate endoscopic removal. In 10 patients US findings of BIB-related complications were: 1) decreased volume with a visible valve (5 cases; in two of these staining of urine was reported); 2) multiple hyperechoic streaks regularly spaced due to a completely collapsed BIB, not modified by decubitus changes (3 cases; one patient reported staining of urine); 3) migration through the bowel (2 cases): in one patient the BIB was passed after 4 days, whereas in the other case bowel obstruction required laparoscopic surgery., Conclusions: In conclusion, US provides a quick and accurate method for the assessment of BIB-related complications in obese patients.

The liver may react to different infectious and non- infectious agents, developing granulomatous lesions which characterize granulomatous hepatitis. Granulomas of the liver are circumscribed inflammatory lesions (size from 50 to 300 mm) composed of epithelioid cells, varied numbers of mononuclear cells and eosinophils and multinucleated giant cells. They represent a specialized cell-mediated immune response to a wide variety of etiological factors. A broad spectrum of microorganisms may trigger hepatic granulomas. M. tuberculosis is the more frequent agent (~ 44%). Granulomatous hepatitis is characterized by a febrile illness with systemic signs and symptoms such as fatigue, sweating, shivering, hepatomegaly and/or splenomegaly, abnormalities in serum liver tests (aminotransferase, alkaline phosphatase). Liver biopsy provides diagnostic information in approximately 15-30% of cases, identifying directly the microbial agent with special microbial stains and polymerase chain reaction or finding distinctive microscopic features, suggestive of specific microorganisms. In such cases appropriate therapy is possible. Unfortunately in one third of cases is impossible to reach aetiological diagnosis on histological criteria alone. In these cases a therapeutic attempt with steroids, effective in the idiopathic granulomatous hepatitis, may be useful.

An immunocompetent 62-year-old woman presented with cutaneous lesions over her right arm and the hypogastrium. The diagnosis of cutaneous cryptococcosis was made on the basis of the demonstration and isolation of Cryptococcus neoformans from the aspirated pus. The patient responded to fluconazole treatment.

Unlabelled: Aim of the study was to evaluate the prevalence and characteristics of non operative spondylodiskitis (SD) in our geographic area., Methods: We evaluated retrospectively epidemiological, clinical, laboratory and radiological features of patients with non operative SD observed between 1990 and 2001 in our department of the "D. Cotugno" hospital - Naples., Results: Eighteen patients with diagnosis of SD were evaluated. Etiologic agent was identified in 17 patients: M. tuberculosis in 5, brucella spp. in 4 and pyogenic bacteria in 8. Ten patients had underlying diseases or risk factors (4 diabetes mellitus, 3 arthrosis, 1 CRF, 1 IVDA and 2 previous back trauma). Symptoms preceded observation between 2 days and 12 months (median value 15 days). Seventeen patients presented fever, 13 back pain, 6 meningitis, 3 were comatous and 2 had severe sepsis. Ten patients showed high white blood cells count with granulocyte prevalence. Eritrosedimentation rate or C reactive protein were elevated in all patients. Diagnosis was confirmed in 8 patients only with radiographs of the spine, while 3 needed a CT and 11 a RMN imaging. Antimicrobial therapy was perfomed for at least 6 months in patients with brucellosis, 12 months in patients with tuberculosis and 2 months in patients with pyogenic SD. Persistent neurological deficit were observed in 2 patients., Conclusions: Neurological deficit may be avoid in patients affected by SD only with a carefull diagnosis and an accurate antibiotic therapy.

Coronary artery aneurysms involve the right coronary artery, the left anterior descending and the left circumflex coronary arteries in descending order of frequency; aneurysms involving the main left coronary artery are extremely rare. Atherosclerosis is the most common cause. Only eleven patients surgically treated with atherosclerotic left main coronary artery aneurysms are reported. We observed the twelfth case of atherosclerotic aneurysm of the left main coronary artery, successfully treated. In a 65-year-old man we found a large aneurysm originating at the distal segment of the left main coronary artery. A thromboendarterectomy was per-formed and was extended back into the left main and down the left anterior descending artery. An aneurysmorrhaphy and a three-vessel coronary artery bypass grafting were also performed. Three years later the patient was asymptomatic. Management of these cases is still controversial and based on anedoctal experience rather than controlled trials. Although surgery has been recommended to prevent complications, there are no available data comparing medical and surgical management. We feel that coronary bypasses should be performed in coronary artery aneurysm patients only when indicated by the severity of stenosis or progressive angina despite medical therapy. It is our opinion that anurysmorraphy should preserve native flow as much as possible.

Background: A prospective randomized trial to compare normothermic CPB with hypothermic CPB has been performed., Methods: 132 patients undergoing CPB were randomized into two groups: group 1 underwent normothermic CPB and group 2 hypothermic CPB (between 26 and 30 degrees C)., Results: Any significant difference was observed between the groups with regard to hospital mortality, blood transfusions, incidence of neurologic deficits and hematocrit, blood hemoglobin levels, platelet counts, plasma concentrations of glutamic-pyruvic transminase, glutamic-oxaloacetic transaminase, creatine kinase, valued at the 12th and 24th postoperative hour and at the 2nd, 3rd, and 4th postoperative day. A significant difference was observed between the groups with regard to tracheal extubation time, discharge time from the intensive care unit and inotropic drug infusion. The normothermic CPB patients group needed shorter time for tracheal extubation and discharge from the intensive care unit: this difference may be ascribed to a shorter inotropic drug infusion. Any increased surgical risks have been observed., Conclusions: In conclusion, we think that normothermic CPB is favourable because it can reduce costs, it can improve the management of a cardiac surgery unit and it is more comfortable for patients.

Primary cardiac rhabdomyosarcoma is rare and its extension to the mitral valve even rarer. We report a case of left atrial rhabdomyosarcoma involving the mitral valve. The patient was a 62-year-old man who complained of recurrent pre-syncopal episodes, dyspnoea often sudden in onset, asthenia and major weight loss (10 kg in one month). 2-D echocardiography revealed a 4.9 cm2 wide mass attached to the atrial side of the anterior mitral leaflet and to the adjacent inferior interatrial septum, where it seemed to have origin. CT scan and scintigraphy revealed bone, kidney and spleen metastases. The patient underwent emergency cardiac surgery because of increasing pre-syncopal and dyspnoeic episodes due to obstruction by the intracardiac mass. At surgery a tumor was found infiltrating the left atrial wall, the interatrial septum, the mitral anulus and the anterior mitral leaflet up to its tip. Invasion of mitral anulus did not allow mitral valve replacement, so that an excision of the intracardiac mass was performed as extensively as possible. Histology revealed a rhabdomyosarcoma. A post-operative chemotherapy cycle had to be stopped due to onset of atrial fibrillation and dyspnoea. 2-D echo monitoring revealed rapid new growth of the tumor across the basal portion of mitral valve leaflet to the atrioventricular orifice. After several episodes of increasing dyspnoea, the patient had a pulmonary oedema and died.

Cardioplegia gave excellent results in a preliminary series of 33 cases in which it was used during surgery. The fact that a sinus rhythm was re-established at the end of extracorporeal circulation in patients in atrial fibrillation suggests that it exerts an antiarrhythmic action at the atrial a level.

A detailed review and analysis of world literature on the techniques employed for the retrieval of polythene catheter fragments, metal spindles or Pudenz catheters from the heart or large vessels is presented. Non-surgical retrieval techniques are discussed on the basis of 174 cases reported in the literature. 2 personal cases of the retrieval of foreign bodies from the heart using a Deyhle-Seubert catheter are presented.

A case of left endoatrial mixoma, ecocardiographically discovered and successfully operated, is reported. The usefulness of ecocardiography, especially to discover intracardiac masses, is considered.
