[INTRODUCTION - Bile duct complications remain a key problem of liver transplantation. Two main types are recognized: anastomotic and intrahepatic. In cases of anastomotic strictures good results can be achieved with surgery or minimally invasive therapy. Intrahepatic stenosis usually requires retransplantation. In this report the results of intrahepatic metallic stent placements are analyzed. PATIENTS AND METHODS - Since 1995, 20 patients with intrahepatic bile strictures were referred for percutaneous treatment. Of 34 percutaneous transhepatic cholangiography, 33 successful drainages were performed and 58 balloon dilatations were employed to overcome. In 13 patients, 20 metallic stents were implanted. One bleeding complication was successfully treated with selective embolization. RESULTS - The average follow up time was 35 months. 14 patients have no symptoms, 12 of them after metallic stent placements and 4 of them after retransplantation (2 patients had metallic stents at retransplantation). One patient has metallic stent and an external drain waiting for retransplantation. Three patients died after 7 retransplantations. Two patients died on the waiting list, one with and one without external drain. There were no deaths after successful metallic stent placement. CONCLUSION - After meticulous preparations metallic stent placement is safe and effective in intrahepatic biliary stenosis after liver transplantation. The patients can be stabilized till the retransplantation, or it can even be avoided.]

[Xanthogranulomatous cholecystitis]

BERÉNYI Zsolt, MORVAY Zita, PALKÓ András

[INTRODUCTION - The xanthogranulomatous cholecystitis is a rare and benign form of lesions associated with diffuse thickening of the gall bladder wall. It is important to recognize it radiologically because it can be mistaken easily for gall bladder carcinoma. The characteristic US, CT and MR findings, however, may be helpful in the differential diagnosis. CASE REPORT - We present the cases of two middleaged female patients suffering from right upper quadrant, radiating abdominal pain for several weeks without occurrence of fever. In both patients, the ultrasound examination revealed marked thickening of the gall bladder wall containing hypoechoic nodules. Further, non-specific sign such as cholecystolithiasis and fine infiltration of the adipose tissue surrounding the gall bladder and dilatation of extrahepatic or intrahepatic bile ducts were visible. On the post contrast CT images, rim enhancement was detectable. MR/MRCP examination showed a sharp delineation of the gall bladder from the liver parenchyma. Both patients underwent cholecystectomy. The pathological examination excluded malignancy and confirmed the diagnosis of xanthogranulomatous cholecystitis. CONCLUSION - The characteristic features of xanthogranulomatous cholecystitis (hypoechoic xanthogranulomas in the markedly thickened gall bladder wall and the presence of calculi) can be detected by ultrasound examination. CT or MRI may play an important role in confirmation of the diagnosis of an inflammatory process and provide useful information in exclusion of gall bladder carcinoma.]

[Transjugular intrahepatic portosystemic shunt implantation in a patient with severe dilatative cardiomyopathy]

SZALÁNCZY Katalin, LÁZÁR István, STEFÁN János, KALÓ Emil

[INTRODUCTION - Indications for TIPS (transjugular intrahepatic portosystemic shunt) are usually portal hypertension induced by alcoholic or viral cirrhosis. Reported patient underwent TIPS because of a rare indication where his rapidly progressing heart failure lead to rapid deterioration of the splanchnic hypertension. CASE REPORT - A 51 years old male was admitted with severe dilatative cardiomyopathy and atrial fibrillation, generalized edema refractory to conservative treatment, and rapidly worsening hepatic laboratory test results. TIPS implantation achieved improvement of all clinical signs, decreased edema and the patient could finally be discharged. CONCLUSION - TIPS can result in improved quality of life not only in primary hepatic cirrhosis but in other clinical circumstances with portal hypertension.]

[Difficulties in the diagnosis of ectopic ureter]

KONCZ Júlia, RÉTI Gyula, NYÁRI Edit, SHAIKH M. Shoaib

[INTRODUCTION - Ureter ectopy refers to the distal opening of the ureter at the site of the bladder neck or lower. 70-80% of the ectopic ureters are associated with pyelectasia and duplicated ureters. The incidence of this is 2-3 times higher in females. CASE REPORT - Following is a case report of a boy who was diagnosed with left-sided pyelectasia during a prenatal ultrasound scan. The postnatal ultrasound revealed a duplicated pelviceal cavity and ureter. The upper pole ureter and the pelvis demonstrated dilatation. At 8 months of age a left side heminehprectomy was performed. Two years postoperatively a follow-up ultrasound revealed a dilatation of the ureteral stump on the left side, which progressed. On MCUG the ureteral stump was identified inserting on to the proximal urethra. Cystography and MR urography demonstrated a ureteral stump which inserted on to the urethra. A repeat surgery was performed to remove the stump. Patient is symptom-free ever since. CONCLUSION - In ectopic, non-refluxing ureters long-term follow-up is necessary following heminephrectomy. A ureter stump besides the bladder can cause serious diagnostical difficulties. Also, it is possible that a dilating stump may lead to a reflux not identified earlier. MCUG and MR urography can help to clear delineate the pathology.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

[The connection between the socioeconomic status and stroke in Budapest]

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

Sandhoff disease is a rare type of hereditary (autosomal recessive) GM2-gangliosidosis, which is caused by mutation of the HEXB gene. Disruption of the β subunit of the hexosaminidase (Hex) enzyme affects the function of both the Hex-A and Hex-B isoforms. The severity and the age of onset of the disease (infantile or classic; juvenile; adult) depends on the residual activity of the enzyme. The late-onset form is characterized by diverse symptomatology, comprising motor neuron disease, ataxia, tremor, dystonia, psychiatric symptoms and neuropathy. A 36-year-old female patient has been presenting progressive, symmetrical lower limb weakness for 9 years. Detailed neurological examination revealed mild symmetrical weakness in the hip flexors without the involvement of other muscle groups. The patellar reflex was decreased on both sides. Laboratory tests showed no relevant alteration and routine electroencephalography and brain MRI were normal. Nerve conduction studies and electromyography revealed alterations corresponding to sensory neuropathy. Muscle biopsy demonstrated signs of mild neurogenic lesion. Her younger brother (32-year-old) was observed with similar symptoms. Detailed genetic study detected a known pathogenic missense mutation and a 15,088 base pair long known pathogenic deletion in the HEXB gene (NM_000521.4:c.1417G>A; NM_000521:c.-376-5836_669+1473del; double heterozygous state). Segregation analysis and hexosaminidase enzyme assay of the family further confirmed the diagnosis of late-onset Sandhoff disease. The purpose of this case report is to draw attention to the significance of late-onset Sandhoff disease amongst disorders presenting with proximal predominant symmetric lower limb muscle weakness in adulthood.

[On February 19, 2022 We celebrate the 205th anniversary of the birth of the first national matronage (head nurse), Zsuzsanna Kossuth. Zsuzsanna Kossuth was characterized by a high degree of empathy, self-sacrifice, exemplary behaviour, and professionalism. She laid the foundation for the processes of nursing and patient care and performed outstanding professional work throughout his life. She made no distinction between man and man, she only saw the suffering patient, in every soldier and injured. She sacrificed his life for his profession. The Hungarian Nursing Association founded the Zsuzsanna Kossuth commemorative medal in 1998, the year of the 150th anniversary of the War of Independence, which is donated every year on February 19.]
