[THE LONG ACTING INSULIN ANALOGUE DETEMIR IN THE DIABETOLOGICAL PRACTICE: EVIDENCE AND POTENTIALS]

TAMÁS GYULA, KERÉNYI ZSUZSA

[Insulin detemir is a neutral, soluble, long-acting insulin analogue in which the amino acid threonineB30 has been removed and the LysB29 acylated with a 14-carbon fatty acid. The fatty acid modification allows insulin detemir to dihexamerisate and reversibly bind to human albumin upon administration. This brand new principle (self association and albumin binding) ensures slow absorption and a prolonged and consistent metabolic effect without a marked peak for up to 24 hours in patients both with type 1 and type 2 diabetes mellitus. Results of large clinical trials have shown that detemir can be efficiently used as basal insulin, supplemented with human regular insulin or aspart insulin taken before the main meals, in both type 1 and type 2 diabetes. Available data clearly demonstrate that the use of this insulin is associated with decreased variability of the fasting blood glucose values. In some of the studies the risk of (mostly nocturnal) hypoglycaemic episodes also dropped. It is important to note that patients using insulin detemir gained less or no weight compared to the group of patients treated with neutral protamine Hagedorn (NPH) insulin. Evaluation of long-term and wide-spread application of detemir needs further observations. Such trials are being conducted worldwide.]

[SOME FORMS OF SECONDARY OSTEOPOROSIS: DIAGNOSIS AND TREATMENT]

GENTI György, PÉNTEK Márta, LICKER-FÓRIS Edit

[Secondary causes of bone loss are not often considered in patients, who are diagnosed as having osteoporosis. There are many causes of secondary osteoporosis, including endocrine diseases, renal disorders, transplantation, glucocorticoid therapy, inflammatory rheumatic diseases etc. This article gives an overview on the most frequent and in the everyday practice important forms of secondary osteoporosis. The first principle is the correct diagnosis and the adequate treatment of the underlying disease. In the prevention and treatment of secondary bone loss similar principles are followed as in the primary forms. Calcium, Vitamin D, personalized, well-aimed physical therapy and continuous physical activity are the basic treatment of secondary osteoporosis. Active form of Vitamin D, which does not require calcium combination, has to be applied in advanced age, in impaired renal function, and in case of ineffective therapy with cholecalciferol. Evidence based data suggest that bisphosphonates (alendronate and risedronate) are the most effective antiresorptive agents in the prevention and treatment of glucocorticoid- induced osteoporosis and in osteoporosis associated with rheumatoid arthritis. To prevent secondary hyperthyreoidism during bisphosphonate treatment, a calcium intake of 1000 1500 mg/d and an 800 IU/d of cholecalciferol are recommended. Ibandronate (150 mg once a month), a new bisphosphonate will be available soon. Parathyroid hormone (teriparatide) is an anabolic agent, that enhances bone formation. Its recent introduction offers new options in the treatment of patients with established osteoporosis.]

[THE ROLE OF STATINS IN THE MANAGEMENT OF PATIENTS WITH ARTERIAL HYPERTENSION]

VÁLYI Péter

[Hypertension and hypercholesterolemia are two very important risk factors of cardiovascular diseases. Statins are the most widely used drugs to treat hypercholesterolemia, and they also modify the efficiency of antihypertensive treatment in patients with hypertension. With the use of statins, a significant reduction in blood pressure has been described both in patients previously untreated and in patients already being treated with antihypertensive drugs. The blood pressure lowering effect of statins is partially independent of their effects on the lipid profile, and is probably related to their interaction with endothelial function, angiotensin-II receptor and other biologically important systems. The ability of statins to improve blood pressure control should be more widely considered when thinking of the complex prevention of cardiovascular diseases.]

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.

Creutzfeldt-Jakob Disease: A single center experience and systemic analysis of cases in Turkey

USLU Ilgen Ferda, ELIF Gökçal, GÜRSOY Esra Azize, KOLUKISA Mehmet, YILDIZ Babacan Gulsen

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 due to the use of topical cyclopentolate hydrochloride

MAHMUT Atum, ERKAN Çelik, GÜRSOY Alagöz

Introduction - Our aim is to present a rare case where a child had delirium manifestation after instillation of cyclopentolate. Case presentation - A 7-year old patient was seen in our outpatient clinic, and cyclopentolate was dropped three times at 10 minutes intervals in both eyes. The patient suddenly developed behavioral disorders along with gait disturbance, and complained of visual hallucinations 20-25 minutes after the last drop. The patient was transferred to intensive care unit and 0.02 mg/kg IV. physostigmine was administered. The patient improved after minutes of onset of physostigmine, and was discharged with total recovery after 30 minutes. Conclusion - Delirium is a rare systemic side effect of cyclopentolate. The specific antidote is physostigmine, which can be used in severely agitated patients who are not responding to other therapies.
