[INTRODUCTION - Primary neoplasm of the great blood vessels is rarely reported. The tumour most commonly presents in the inferior vena cava. In general, the prognosis is very poor, since intimal sarcomas metastasise early, and mural sarcomas grow silently and remain hidden for a long time. Also, because this type of tumour is so uncommon, it is often not considered for diagnosis. CASE REPORT - We report on the case of a 77- year-old woman with progressive symmetric oedema of the lower limbs. The investigations revealed a tumour thrombus that obliterated the inferior vena cava in its entire length. No surgery was possible because of the advanced stage of the disease. Later, Budd-Chiari syndrome developed and the patient died of progressive hepatic failure. The tumour was initially thought to be that of extravascular origin breaking into the vein. However, autopsy revealed a primary tumour of vascular origin, which histologically proved to be a leiomyosarcoma. CONCLUSION - Today, the recognition of the insidiously growing vascular mural sarcomas is assisted by an entire diagnostic arsenal. It is important, however, that the possibility of this rare disease is considered in time to permit surgical removal, the only treatment that can prolong survival. The authors would like to contribute to this by presenting this rare clinical case.]

[MODERN TREATMENT OF COLORECTAL CANCER]

KALMÁR Katalin, HORVÁTH Örs Péter

[The incidence of colorectal cancer has dramatically increased in the past decades, rendering it the second most frequently diagnosed cancer in the Western world. Disease outcome can be improved both by early diagnosis, e.g., through the introduction and extension of screening programs, and by increased therapeutic efficiency. The latter is achieved by increasing the radicality of interventions in surgical oncology to total mesorectal excision, thereby significantly decreasing the frequency of local recurrence. High ligation of the inferior mesenteric artery aims to enhance the efficiency of lymphadenectomy. With the introduction of techniques that spare vegetative nerves, the quality of life will not be adversely affected by the increased radicality. Another direction of progress in colorectal surgery is the increased use of minimally invasive approaches, such as local excision by transanal endoscopic microsurgery or laparoscopic methods. Increased acceptance of a multimodality approach, i.e., combined application of surgical and oncological methods in the treatment of colorectal cancer, has been a great step forward recently. Beyond the long-applied adjuvant treatments, the pre-surgical use of neoadjuvant chemo-radiotherapy has become standard for locally advanced rectal cancers. Adjuvant and neoadjuvant chemotherapy also supplements the surgery of metastases with improving results and impressive long-term survivals. A very important prerequisite for tailored multimodality treatment is reliable staging, which is facilitated by the wider availability of endorectal ultrasound.]

[STATE-OF-THE ART COMPLEX TREATMENT OF THYROID CANCERS]

LUKÁCS Géza

[Thyroid cancers derived from follicular epithelial cells are histologically classified as papillary, follicular and anaplastic. Cancers that originate from parafollicular, or C-cells, are termed medullary carcinomas. Their annual incidence is fairly low; 3 to 7 cases per 100 000 people. After the Chernobyl disaster, however, thyroid cancers have received much attention. They often occur at young age, and frequently and early give metastases. They typically grow slowly and have a good prognosis even in the metastatic stage. The main prognostic factors include age, tumour size and extent, the completeness of surgical removal, distant metastases and tumour grade. Based on these parameters, they are classified into high-risk and low-risk groups. There are no prospective randomized studies available on the optimal treatment of thyroid cancers. Their biological aggressiveness differs according to geographic location, which explaines why the management of thyroid carcinomas has not been standardized internationally. Contrary to America and Australia, in Europe there are several endemic goitre regions, and background radiation is higher. It is generally accepted that here the standard therapy of choice is total thyreoidectomy with adequate lymph node dissection followed by postoperative radioiodine ablation. It is a reasonable demand to minimize the higher morbidity associated with radical surgery (e.g., recurrent nerve palsy, postoperative hypoparathyroidism) below 1%. It is recommended that such operations are performed by experienced thyroid surgeons in centres with multidisciplinary endocrine teams.]

JÓZSA Andrea, SZÉKELY Iván, SIMON János, MÁHR Árpád, HORVÁTH László, HORVÁTH Andrea, FEJES Roland, SZÉKELY András, SZABÓ Tamás, MADÁCSY László

[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.]

Autonomic nervous system may be affected after carpal tunnel syndrome surgery: A possible mechanism for persistence of symptoms after surgery

ONDER Burcu, KELES Yavuz Betul

After carpal tunnel surgery, some patients report complaints such as edema, pain, and numbness. Purpose – The aim of this study was to evaluate autonomic nervous system function in patients with a history of carpal tunnel surgery using sympathetic skin response (SSR). Thirty three patients (55 ±10 years old) with a history of unilateral operation for carpal tunnel syndrome were included in the study. The SSR test was performed for both hands. Both upper extremities median and ulnar nerve conduction results were recorded. A reduced amplitude (p=0.006) and delayed latency (p<0.0001) were detected in the SSR test on the operated side compared to contralateral side. There was no correlation between SSR and carpal tunnel syndrome severity. Although complex regional pain syndrome does not develop in patients after carpal tunnel surgery, some of the complaints may be caused by effects on the autonomic nervous system.

Simultaneous subdural, subarachnoideal and intracerebral hAemorrhage after rupture of a peripheral middle cerebral artery aneurysm

BÉRES-MOLNÁR Anna Katalin, FOLYOVICH András, SZLOBODA Péter, SZENDREY-KISS Zsolt, BERECZKI Dániel, BAKOS Mária, VÁRALLYAY György, SZABÓ Huba, NYÁRI István

The cause of intracerebral, subarachnoid and subdural haemorrhage is different, and the simultaneous appearance in the same case is extremely rare. We describe the case of a patient with a ruptured aneurysm on the distal segment of the middle cerebral artery, with a concomitant subdural and intracerebral haemorrhage, and a subsequent secondary brainstem (Duret) haemorrhage. The 59-year-old woman had hypertension and diabetes in her medical history. She experienced anomic aphasia and left-sided headache starting one day before admission. She had no trauma. A few minutes after admission she suddenly became comatose, her breathing became superficial. Non-contrast CT revealed left sided fronto-parietal subdural and subarachnoid and intracerebral haemorrhage, and bleeding was also observed in the right pontine region. The patient had leucocytosis and hyperglycemia but normal hemostasis. After the subdural haemorrhage had been evacuated, the patient was transferred to intensive care unit. Sepsis developed. Echocardiography did not detect endocarditis. Neurological status, vigilance gradually improved. The rehabilitation process was interrupted by epileptic status. Control CT and CT angiography proved an aneurysm in the peripheral part of the left middle cerebral artery, which was later clipped. Histolo­gical examination excluded mycotic etiology of the aneu­rysm and “normal aneurysm wall” was described. The brain stem haemorrhage – Duret bleeding – was presumably caused by a sudden increase in intracranial pressure due to the supratentorial space occupying process and consequential trans-tentorial herniation. This case is a rarity, as the patient not only survived, but lives an active life with some residual symptoms.

Isolated hypoglossal nerve palsy due to a jugular foramen schwannoma

ÖZTOP-CAKMAK Özgür, VANLI-YAVUZ Ebru, AYGÜN Serhat, BASTAN Birgül, EGEMEN Emrah, SOLAROGLU Ihsan, GURSOY-OZDEMIR Yesemin

Introduction – Although the involvement of the hypoglossal nerve together with other cranial nerves is common in several pathological conditions of the brain, particularly the brainstem, isolated hypoglossal nerve palsy is a rare condition and a diagnostic challenge. Case presentation – The presented patient arrived to the hospital with a history of slurred speech and an uncomfortable sensation on his tongue. Neurological examination showed left-sided hemiatrophy of the tongue with fasciculations and deviation towards the left side during protrusion. Based on the clinical and MRI findings, a diagnosis of hypoglossal nerve schwannoma was made. Discussion – Hypoglossal nerve palsy may arise from multiple causes such as trauma, infections, neoplasms, and endocrine, autoimmune and vascular pathologies. In our case, the isolated involvement of the hypoglossal nerve was at the skull base segment, where the damage to the hypoglossal nerve may occur mostly due to metastasis, nasopharyngeal carcinomas, nerve sheath tumors and glomus tumors. Conclusion – Because of the complexity of the region’s anatomy, the patient diagnosed with hypoglossal nerve schwannoma was referred for gamma knife radiosurgery.

To handle the HaNDL syndrome through a case: The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis

ÇOBAN Eda, TEKER Ruken Serap, SERİNDAĞ Helin, SAKALLI Nazan, SOYSAL Aysun

The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis (HaNDL) is a rare entity. This disease has been related to migrainous headaches. It is a benign, self-limited disorder, which is characterized by fluctuating neurological symptoms and cerebrospinal fluid lymphocytosis. We describe a case of a 47 years old man with acute onset of headache and aphasia. Cerebrospinal fluid analysis revealed a lymphocytic pleocytosis (25 cells/μl, 100% lymphocytes). Electroencephalogram showed moderate slow rhythm in the left hemisphere, with temporoparietal predominance, and without epileptiform activity. His blood tests as well as magnetic resonance imaging (MRI) results were normal. With the diagnosis of HaNDL syndrome the patient was accepted in the Department of Neurology and discharged with full recovery.

[Percutaneous coronary intervention in ischaemic heart disease]

VOITH László

[In ischaemic heart disease, if the medically treated patient’s anginal complaints and/or ischaemic symptoms are persistent, coronary angiography, and according to its results, coronary intervention (surgery or dilatation) may become necessary. The intervention is required in critical stenosis (>70% diameter) of the main vessels, the emergency depends on the clinical situation. Basic method of coronary angioplasty is the balloon dilatation, other tools (stent, rotablator, laser wire, atherectomy device, etc.) are also available. Periprocedural anticoagulant (heparin) and platelet aggregation inhibitor (aspirin, ticlopidine, GP IIb/III/a receptor blocker) treatment is required, the latter after the procedure as well. After stent implantation the lumen of the vessel is bigger and the incidence of major adverse cardiac events (acute myocardial infarction, repeated intervention, fatal outcome) is diminished. Decrease of serum lipid level improves the outcome of coronary angioplasty. It is applicable successfully for multiple lesions, occluded vessels, stable and unstable angina, in the early phase of myocardial infarction, in patients who underwent coronary surgery, and in old age too. Risk factors of the intervention are: tortuous vessel, significant calcification, stenosis in angle or ostium, luminal thrombus, urgent intervention, old age, female gender, congestive heart failure, unstable condition and acute myocardial infarction. When indicating the intervention, besides the probable results, it is necessary to consider the possibility of complications (myocardial infarction, malignant rhythm disorders, acute heart failure, bleeding, etc.). In left main stem stenosis, 3 vessel disease and in the case of 1 functioning coronary artery surgery would be preferable. With the present facilities the ratio of urgent surgical intervention as well as the mortality is below 1%.]
