[Drug use and death-seeking behaviour attitudes toward death among opiate users]

PAP Ágota, HEGEDÛS Katalin

[Many times, behind mens’ fears there is the fear of death. Drug use can be defined as a kid of self destruction, so it is directly linked to attitudes toward death. In Hungary, suicide among young people is one of the leading causes of death, which is often associated with some kind of addiction or substance abuse. We can also say that drug use is an indirect way of “death search”, which prolongs the agony and the time of suffering. Drug-related death can be directly attributed to drug overdose. Intravenous drug use may cause a risk of infectious diseases (such as sharing needles/syringe/filter use) - HCV, AIDS, etc. Intravenous drug use is mostly - but not exclusively - characteristic to opiate users. Heroin’s mode of action is described as causing an intense feeling of euphoria and a way of feeling augmenting to stupor. Its addictive potential is very high, the degradation is visible and can be fatal. In this paper, we discuss previous observations on overdose that is the validity of harm reduction justified by former research, the possible predictors of overdose and the identification of the prevention area.]

[Prevention of infections in patients with absent or dysfunctional spleen: adaptation of international guidelines]

KULCSÁR Andrea

[Individuals with an absent or dysfunctional spleen are at increased risk of severe infection. The greatest risk of infection is within two years after splenectomy. A spectrum of infecting microorganisms may cause serious infections, especially in young or immunocompromised patients. The commonest pathogens are Streptococcus pneumoniae, Neisseria meningitidis and in some countries Haemophilus influenzae type b (Hib). The international guidelines for the prevention and treatment of infection in patients with an absent or dysfunctional spleen are inconsistent. Most of the evidence is obtained from expert committee reports or opinions and/or clinical experiences of respected authorities. This area in Hungary also represents an unmet need. Patients who have undergone surgical removal of the spleen and those with medical conditions that may predispose to functional hyposplenism must be educated about the danger of their condition, must be immunised and must be treated with prophylactic antibiotics according to national epidemiological and microbiological protocols. In Hungary we have an urgent need for a definite guideline for infection profilaxis of individuals with an absent or dysfunctional spleen. This paper is written by a vaccination consultant with the intention of raising awareness and to provide some assistence for physicians and their patients.]

[Lixisenatide: a new GLP-1-receptor agonist with mainly prandial effect for the treatment of patients with type 2 diabetes]

JERMENDY György

[Recently, lixisenatide, a new incretin mimetic GLP-1-receptor agonist with a mainly prandial effect has been registered for the treatment of patients with type 2 diabetes mellitus. The amino acid sequence of lixisenatide and that of human native GLP-1 is 50% identical. Due to its altered amino acid sequence and conformation, lixisenatide is resistant to inactivation by DPP-4. Lixisenatide is a specific agonist of GLP-1- receptors and its binding has a pharmacologic GLP-1-agonist effect. Lixisenatide is used subcutaneously, its normal daily dose is 1×20 μg. It is mostly used in combination with metformin, but it can be also used to supplement sulfanylurea or basal insulin therapy. Clinical efficiency of lixisenatide has been investigated in the phase-III GetGoal trials. In these trials, adequate glycaemic control and a marked decrease in postprandial blood glucose values were observed. During lixisenatide therapy, a decrease in body weight and no substantial increase in the risk of hypoglycaemia were observed, whereas transient gastrointestinal side effects might occur after initiation of treatment. Lixisenatide as an add-on treatment to basal insulin should be considered as a new treatment approach in the management of type 2 diabetes.]

[A novel rapid IL-6 release assay using blood mononuclear cells of patients with various forms of drug induced skin injuries]

BALÓ-BANGA J. Mátyás, SCHWEITZER Katalin

[INTRODUCTION - IL-6 is a multifunctional cytokine with effects on the haematopoiesis on differentiation of T and B lymphocytes and on the regulation of both inflammatory and allergic reactions. The question arose whether this substance excreted by mononuclear cells could be used as a marker of allergy to drugs or not. Till now equivocal descriptions were lacking. METHOD - The preformed IL-6 present in the mononuclear cells released by any of four standard dilutions of pure substances upon 20 minutes incubation was determined from the supernatants by ELISA technique. In vivo patch, intradermal and provocation tests were carried out along with this assay (483 in vitro and 172 in vivo). RESULTS - Two different groups suspect for drug allergy (100 and 62 patients as well as their matching controls, 24 and 23 persons) were involved with these procedures. In some cases TNF-α, IL-2, IFN-γ and IL-4 was measured simultaneously by flow cytometric assay. Only TNF-α and IL-6 were present in the 20 min. supernatants. The comparisons with in vivo tests have confirmed that the amount of IL-6 release had not depended either on the clinical phenotype of allergy or on the structure of the tested drugs within the molecular mass range between 76-4000 Da. IL-6 released at the lowest or multiple concentrations of drugs coincided with more severe and widespread clinical forms. CONCLUSION - Based on the results we elaborated an in vitro method applicable clinically for detecting drug sensitisation and its differential diagnosis in patients with skin signs of drug sensitisation.]

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.

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning.

We aimed to analyze the clinical, laboratory and neuroimaging findings in patients with sporadic Creutzfeldt-Jakob disease (CJD) in a single center as well as to review other published cases in Turkey. Between January 1st, 2014 and June 31st, 2017, all CJD cases were evaluated based on clinical findings, differential diagnosis, the previous misdiagnosis, electroencephalography (EEG), cerebrospinal fluid and cranial magnetic resonance imaging (MRI) findings in our center. All published cases in Turkey between 2005-2018 were also reviewed. In a total of 13 patients, progressive cognitive decline was the most common presenting symptom. Two patients had a diagnosis of Heidenhain variant, 1 patient had a diagnosis of Oppenheimer-Brownell variant. Seven patients (53.3%) had been misdiagnosed with depression, vascular dementia, normal pressure hydrocephalus or encephalitis. Eleven patients (87%) had typical MRI findings but only 5 of these were present at baseline. Asymmetrical high signal abnormalities on MRI were observed in 4 patients. Five patients (45.4%) had periodic spike wave complexes on EEG, all appeared during the follow-up. There were 74 published cases in Turkey bet­ween 2005 and 2018, with various clinical presentations. CJD has a variety of clinical features in our patient series as well as in cases reported in Turkey. Although progressive cognitive decline is the most common presenting symptom, unusual manifestations in early stages of the disease might cause misdiagnosis. Variant forms should be kept in mind in patients with isolated visual or cerebellar symptoms. MRI and EEG should be repeated during follow-up period if the clinical suspicion still exists.

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.
