[Almost 80 percent of poison-related deaths are caused by drugs. The overwhelming majority of today's clinical toxicological work is comprised of cases of toxic level drug overdose, drug mixups, adverse effects during therapeutic drug administration, as well as intoxication from drug abuse. A prerequisite of adequate therapy of intoxication is the qualitative and quantitative determination of the compounds causing it. The two elements of systematic toxicological analysis are the screening test and the confirmatory test. The review touches on the toxicologic use of the hyphenated chromatographic-spectroscopic instruments and on the alternative biological matrices. It is known that the effects and toxic side-effects of many drugs show substantial interindividual differences even in the same doses. One of the possible causes of this phenomenon is a genetically determined polymorphic drug metabolism. Some pharmacogenetically determined anomalies in drug administration, particularly enzyme inhibition and induction, are of clinical toxicological importance.]

[Interdisciplinarity, workplace stress, holistic management]

SZABÓ Nóra, SZABÓ Gábor, HEGEDÛS Katalin

[INTRODUCTIONS – The physical and psychological condition of health care professionals dealing with the seriously ill is worse than that of those caring for not seriously ill patients. This may be due to the nurses' dissatisfaction, vital exhaustion, workplace stress, social support and the degree of professional and social adjudication. The aim of the survey is to comparatively investigate two groups dealing with the seriously ill – hospice nurses and nurses caring for elderly patients. Hypothesis: hospice nurses are in a more favourable position than nurses caring for elderly patients in terms of satisfaction, vital exhaustion, social support, the degree of workplace stress and professional and social acknowledgement as well. SUBJECTS AND METHODS – The survey was performed among hospice nurses (N=25) and nurses caring for elderly patients (N=50) using a self-assessment questionnaire. The inventory comprised questions related to demographical, professional and social acknowledgement and questionnaires on satisfaction, vital exhaustion, social support and workplace stress. RESULTS – In terms of social support hospice nurses are clearly in a more favourable position than those caring for elderly patients. Workplace stress is higher among nurses caring for elderly patients than that of hospice nurses thus the adverse effects of workplace stressors will more readily appear among nurses working with the elderly. CONCLUSION – The interdisciplinary approach of hospice, the acceptance and inclusion of professionals from fields other than nursing and medicine into the practical care may promote holistic care and the acceptance and acknowledgement of nurses. The greater social support may reduce the nurses’ degree of workplace stress and thus the adverse consequences of workplace stressors. Therefore in the future interdisciplinarity should be extended, communication between specialties should be encouraged within the care for the elderly and – as a matter of fact – on each level and field of the health care system.]

[Modern surgical treatment of lung cancer]

AGÓCS László

[Lung cancer is one of the most malignant human cancers because of its high incidence and high mortality rate. The 5-year relative survival rate for lung cancer at the initial diagnosis is 5-15%. Stage I or stage II non-small cell lung cancer (NSCLC) are considered early stage disease. Unfortunately, these two stages combined account for only 25 to 30% of tumours at the initial detection. At present, surgical resection remains the recommended treatment for patients with stage I and II NSCLC. Despite negative preoperative staging studies including mediastinoscopy, as many as one fourth of the patients will be found at surgery to have an occult N2 or one nodal station positive metastatic – stage IIIA – disease. Multimodality therapy is preferred for all subsets of stage IIIA patients. In stage IIIB and IV, surgical resection is possible and indicated only in selected cases, including Pancoast tumours, T4N0,1M0 tumours, the presence of satellite nodules in the same lobe, and certain solitary metastases. Patients with clinical stage T1-2 N0 small cell lung cancer (SCLC) may benefit from surgery for confirmation of diagnosis and improved local control when combined with chemotherapy. The mortality and morbidity rates of surgery in the treatment of lung cancer are reasonably low.]

[Relationship between the efficacy of atypical antipsychotics and polymorphism of dopamine D3 receptor in schizophrenia]

SZEKERES György, JUHÁSZ Anna, KÉRI Szabolcs, RIMANÓCZY Ágnes, SZENDI István, SZABÓ Zoltán, JANKA Zoltán

[Object - Numerous relevant variants of dopamine receptors have been identified in schizophrenia. The Ser9Gly gene polymorphism of dopamine D3 receptor is known as a susceptibility factor for the disease. In addition, it has a role in the modification of therapeutic effect of antipsychotics. In this naturalistic study the authors investigated the relationship between this polymorphism and the therapeutic response to atypical antipsychotics. Method - 75 patients with schizophrenia according to DSM-IV and 45 healthy controlls were recruited. The patients were divided to responder and nonresponder subgroups, cut-off: >20 point improvement in Global Assessment of Functioning. By polymerase chain reaction the genotype of dopamine D3 receptor of every participant was determined. Results - The Ser9Ser genotype of dopamine D3 receptor was more frequent in the nonresponder subgroup (64%, p=0.0018). The Ser9 allele was overrepresented among nonresponder patients (82%, p=0.0172). Conclusion - Based on our results, the worse therapeutic response to atypical antipsychotics is associated with Ser9 variant of dopamine D3 receptor.]

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.

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.
