[INTRODUCTION – Variceal haemorrhage from the oesophageal or gastric wall is a major cause of death in patients with chronic liver disease. Over the past two decades many new treatment modalities have been introduced in the management of variceal bleeding, such as emergency endoscopy, band ligation and postintervention observation of the bleeding patients in subintensive care units. This study presents the results of state-of-the-art therapy applied in our department, comparing them to published data. PATIENTS AND METHODS – Clinical records of patients with variceal haemorrhage admitted to our department between January 1st 2001 and December 31st 2004 were reviewed. Six-week mortality, incidence of recurrent bleeding, transfusion requirement and length of hospital stay were the main parameters analysed. RESULTS – A total of 228 admissions (191 patients) due to variceal bleeding were recorded in the study period. Cirrhosis was of alcoholic origin in 92% of patients. Upper endoscopy was performed in 94% of patients within 4 hours and endoscopic therapy was also applied in all but 7 patients. Octreotide was administered in 4 patients, and portosystemic shunt was performed in 1 patient. Primary endoscopic haemostasis was achieved in 85% of cases, while rebleeding rate was 31%. The mean length of total hospital stay was 10.6 days, including an average of 2.6 days in subintensive care units. The mean transfusion requirement was 3.75 units of packed red cells. Six-week mortality rate was 14.9%. CONCLUSION – In comparison to international data, the six-week mortality rate among our patients was substantially lower than that in earlier reports, and nearly equals with recent leading results.]

[THE GENETICS OF INFLAMMATORY BOWEL DISEASE]

LAKATOS Péter László, LAKATOS László

[The pathogenesis of inflammatory bowel disease is only partly understood; various environmental and host factors (e.g., genetic, epithelial, immune and non-immune) are involved. It is a multifactorial polygenic disease probably with genetic heterogeneity; some genes confer susceptibility to IBD in general, while others specifically increase the risk of ulcerative colitis or Crohn's disease or affect location (localized or extensive) and/or behaviour (e.g., mild, severe, aggressive). This review presents recent advances in the genetics of inflammatory bowel disease including chromosome segments newly recognized to be involved in inflammatory bowel disease as well as the role of NOD2/CARD15, SLC22A4/A5 and DLG5. The increasing genetic information provides, for the time being, a better understanding of the pathogenesis of the disease thus setting a basis for potential targets for therapeutic intervention. In the future, however, genetics may also help in refining the diagnosis or predicting disease course.]

[Endoscopic, posterior transseptal pituitary surgery - Learning curve of the surgical technique and equipment in 61 operations]

BELLA Zsolt, FÜLÖP Béla, CSAJBÓK Éva, MAGONY Sándor, VALKUSZ Zsuzsa, HERCZEGH Szilvia, JÓRI József, BODOSI Mihály, CZIGNER Jenő, BARZÓ Pál

[Introduction - The removal of hypophyseal tumor by transsphenoidal pituitary surgery using microsurgical instruments was first performed over 100 years ago. Operating techniques for this surgery are constantly being renewed, first by using a microscope and later on with the use of an endoscop. The authors provide an overview of the minimal invasive posterior transseptal-transsphenoidal aproach with the combined utilization of classical techniques with the assistance of the endoscop. Method - Sixty-one patients (33 female, 28 male, 21-84 yrs) were treated for sellar region tumor resection using an endonasal transsphenoidal aproach with the help of an endoscop. Follow ups were performed within 2-21 months. Results - Total tumor resection was successful in 91.8%, and partial resection in 8.2% of the patients. The rate of complications using the endoscop method was not higher compared to that of the classical microscopic method. There was no major bleeding in any of the cases. Adverse events such as minor epistaxis occurred in 4.9%, transitional diabetes insipidus in 6.5%, inraoperative CSF leak in 16.67%, postoperative CSF leak in 11.5% and meningitis in 8.2% of the patients. After the operation the pathological hormonal production stoped in all patients except in two patients who were acromegalic. However their GH level normalized and they did not require further treatment, the IGF-1 still remained high. Conclusion - The success of the surgical treatment is based on both, the proficient pre- and postoperative endocrinological care, and the minimal invasive surgical technique. The endoscop was used partially or continuously during the operation for better visualization of the operation field in multiple angles (30°, 45°). It was useful in differentiating between normal and tumorous glandular tissue, and also offered an enhanced view of the intrasellar (via hydroscopy) and parasellar region. Moreover the endoscopic method is able to decrease the operating time, reduce blood loss. In different stages of the surgery, depending on the anatomical and pathological situation, switching back and forth from microscope to endoscop technique, gives us the benefit of a clearer view in each situation.]

[INTRODUCTION - Central nervous system complications occur in 1% of patients with Mycobacterium tuberculosis infection, but the mortality is very high, about 50 percent. CASE REPORT - A 1-year-old child in tenebrous condition was admitted to the hospital with suspicion of meningitis. MRI detected disseminated encephalitis and dilated ventricles. Examination of the serum and cerebrospinal fluid didn’t bring any results. The microscopic examination of the brain biopsy raised the possibility of tuberculous meningoencephalitis, and the culture and PCR from the brain tissue revealed meningoencephalitis caused by Mycobacterium tuberculosis Beijing. DISCUSSION - Tuberculous meningitis is a very rare, but severe consequence of extrapulmonary tuberculosis. Due to the high mortality, early diagnosis and whenever suspected, the use of empiric antituberculotic therapy are the only chances of recovery.]

[Diagnostic problems of ischemic colitis]

DEMETER Pál, SIKE Róbert, SZÉKELY György, KISS Sándor, SZILVÁS Ágnes

[Ischemic colitis is mainly caused by the impaired circulation of the inferior mesenteric artery. Most frequently it occurs as part of general arteriosclerotic disease or impaired left ventricular function, but it may also occur after abdominal aortic reconstruction. In connection with cocaine users, thrombophylia and vasculitis can also happen among young patients. Colonoscopy plays the most important role in making the diagnosis. In case of transitional ischemia conservative treatment is recommended, but surgery is needed in the progressive gangrenous form or when stricture in the colon developed. Authors describe the case of an 80-year-old man and discuss the etiology, clinical aspects, classical and up-to-date methods of diagnostics and the possibilities of conservative treatment.]

[WEGENER’S GRANULOMATOSIS PRESENTING AS MASTOIDITIS: A DIAGNOSTIC CHALLENGE]

NAGY Pál, Z. SZABÓ László, DOMJÁN Gyula, GADÓ Klára, BALOGH Károly

[INTRODUCTION - Wegener's granulomatosis has an uncertain pathomechanism, but is probably autoimmune in origin. In typical cases the mucosa of the nose, paranasal sinuses and of the lower respiratory tract, as well as the lungs and the kidneys are affected. Patients present with sinusitis, recurrent pneumonia or renal disease associated with microhaematuria, pyuria or azotaemia. Fever, polyarthralgia or polyarthritis may also occur. The underlying pathologic changes are necrotizing vasculitis, granulomas and parenchymal necrosis. The diagnosis is based on a combination of the clinical picture, microscopic findings and immunofluorescent demonstration of cANCA. CASE REPORT - A 27-year-old woman presented with symptoms of unilateral mastoiditis. In the following 7 months she underwent 7 operations in 4 hospitals for a locally progressive, destructive process of uncertain etiology showing a septic course. The clinical picture was not specific, the cANCA test was not definitive, and the histologic findings were initially interpreted as nonspecific inflammation. Repeated biopsies, multiple reviews of the microscopic specimens, consultations, differential diagnostic considerations, and, finally, the success of the treatment with corticosteroids and cyclophosphamide led to the diagnosis of Wegener’s granulomatosis. Currently the patient has been in remission for 32 months. CONCLUSION - The definitive diagnosis of Wegener’s granulomatosis, particularly of its localized or limited form, may be problematic despite well-defined diagnostic criteria. Setting up the correct diagnosis may take months or years. In case of unusual respiratory or otological symptoms, and in view of ineffective medical or surgical treatment, Wegener’s granulomatosis has to be considered. An atypical clinical picture, inconclusive histologic, radiologic and laboratory findings warrant the need for close collaboration of various specialists. This is particularly important since state-of-the-art therapy of Wegener’s granulomatosis promises a favourable prognosis.]
