[INTRODUCTION - Superior mesenteric artery syndrome is caused by vascular compression of the inferior transverse part of the duodenum due to the anomalous course of the superior mesenteric artery and/or a cranial shortening of the ligament of Treitz. Clinical caracteristics include postprandial epigastric pain, nausea, vomiting of bile, slow passage in the gastroduodenal passage, and as a consequence of the above, pernicious weight loss. CASE REPORT - In the case of a 35-year old woman with chronic abdominal symptoms for 6 years and 20 kg weight loss, CT-enterography revealed superior mesenteric artery syndrome. We identified an abnormally acute aortomesenteric angle of 7.3 degrees and a highly inserted ligament of Treitz as predisposing factors. We presume that the immediate cause of the development of severe vascular compression, in the case of our patient, was progressive weight loss due to a persistent Epstein-Barr virus infection. CONCLUSION - First in Hungarian literature we review the etiology, the radiological signs, the procedure of differential diagnosis, and the treatment options of superior mesenteric artery syndrome.]

[Focus on the diagnosis and therapy of chronic cough]


[Cough by itself is not a disease but a part of a complex defense mechanism protecting from harmful materials entering the airways and cleaning the lungs and airways from potentially harmful materials. Normally, cough is accompanied by other defense mechanisms (bronchoconstriction and secretion of sputum) that increase the effectiveness of cough. Cough generally is caused by intrapulmonary disorders, but may be related to extrapulmonary lesions that are not easy to diagnose. In every case, an etiological diagnosis has to be the aim because this is the only way to proper treatment. From the abundance of reasons for cough, upper airway cough syndrome, asthma, chronic obstructive pulmonary disease, and gastro-esophageal reflux disease are discussed in detail.]

[Tumor necrosis factor-alpha blockade: adverse clinical consequences and safety issues]

MŰZES Györgyi

[The pleiotropic cytokine tumor necrosis factor (TNF)-α seems to be fundamentally involved in the pathogenesis of a variety of immune-mediated (partly autoimmune) chronic inflammatory disorders; therefore, its blockade has allowed a remarkable advance in treatment strategies. Safety and tolerability profile of TNF-antagonists is generally favorable, their overall risk/benefit ratio is definitely positive. Possible adverse consequences related to TNF-α blocking monoclonal antibodies and soluble receptors can be classified as class-specific side effects that are related to their mode of action, and individual, molecule-specific effects. Immunogenic potential of immunoglobulins (Ig) eliciting an anti-(Ig-) antibody immune response may reduce or eliminate their therapeutic benefit, increase the risk of resistance or intolerance to biologic agents, and also lead to other adverse clinical effects. The immunogenicity profile of TNFantagonists is mainly related to their hetero- (xeno-), allo- (iso-)genic or idiotypic antigen character. By means of generating fully human monoclonal antibodies, more tolerable drugs could be introduced into clinical practice.]

[Necessity of a shift in attitudes in the judgment and therapy of skin and soft-tissue infections]


[Skin and soft-tissue infections are defined as infections of the epidermis, dermis, or subcutan tissue. They are among the most common human bacterial infections observed in clinical practice. It has also been shown that the incidence of skin and soft-tissue infections is increasing. This has been attributed to several factors, including increasing population age, surgical wounds related to more invasive surgery in the ageing population, obesity, malnutrition, diabetes, peripheral vascular disease and decreasing immunocompetence. There has been a major increase in the occurrence of Staphylococcus aureus infections, and communityacquired methicillin-resistant S. aureus (MRSA) infections in particular. Although many cases of skin and soft-tissue infections can be successfully treated using empirical antimicrobial therapy, changing resistance patterns of S. aureus isolates necessitate new treatment strategies.]

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.

Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.

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


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.

Extraskeletal, intradural, non-metastatic Ewing’s sarcoma. Case report


Intracranial localization of Ewing’s sarcoma is considerably very rare. Herein, we present clinical and neuroimaging findings regarding a 4-year-old boy with intracranial Ewing’s sarcoma. He was born prematurely, suffered intraventricular haemorrhage, posthaemorrhagic hydrocephalus developed, and a ventriculoperitoneal shunt was inserted in the newborn period. The patient endured re­gular follow ups, no signs of shunt malfunction nor increased intracranial pressure were observed. The last neuroima­ging examination was performed at 8 months of age. Upon reaching the age of 4 years, repeated vomiting and focal seizures began, and symptoms of increased intracranial pressure were detected. A brain MRI depicted a left frontoparietal space-occupying lesion infiltrating the superior sagittal sinus. The patient underwent a craniotomy resulting in the total excision of the tumour. The histological examination of the tissue revealed a small round blue cell tumour. The diagnosis was confirmed by the detection of EWSR1 gene translocation with FISH (fluorescent in situ hybridization). No additional metastases were detected during the staging examinations. The patient was treated in accordance to the EuroEwing 99 protocol. Today, ten years onward, the patient is tumour and seizure free and has a reasonably high quality of life.
