[The importance of balneotherapy in osteology]

BENDER Tamás, KULISCH Ágota, KOVÁCS Csaba, HORVÁTH Katalin, GYARMATI Noémi, TEFNER Ildikó

[The authors overview the role of hydroand balneotherapy in osteology. As Hungary is very rich in thermal-mineral water, this kind of therapy has a great importance in the rehabilitation of locomotor diseases. In the past years, an increasing number of data have been published about the immunomodulatory, metabolic and analgesic role of hydro- and balneotherapy. Although balneotherapy’s mechanism of action has not been clarified yet, a number of reviews and metaanalyses have found that hydro- and balneotherapy have a beneficial effect on locomotor diseases. The majority of these articles - many of them written by Hungarian authors - discusses the treatment of arthrosis. Furthermore, an increasing amount of data is available on calcium supplementation with mineral water. In this paper, we discuss the role of hydro- and balneotherapy in the therapy of osteological diseases, on the basis of the available evidence.]

[Cost minimization analysis of basal insulin analogues in the treatment of type 2 diabetes]

MERÉSZ Gergő, TABÁK Gy. Ádám, KALÓ Zoltán

[INTRODUCTION - Basal insulin analogues are essential drugs for the treatment of type 2 diabetes mellitus. Basal insulin analogues have been shown to reduce the frequency of hypoglycaemia versus NPH insulin, and thus may be beneficial in the treatment of type 2 diabetes. Here we present a cost-minimisation analysis of basal insulin analogues, comparing insulin glargine and insulin detemir available in Hungary. METHODS - A literature review was conducted to identify randomized, controlled clinical trials with a duration of 12 weeks or more in which a direct comparison of insulin glargine and insulin detemir was made in patients with type 2 diabetes. In a meta-analysis of the eligible trials, the following endpoints were investigated: metabolic status, body weight, frequency of hypoglycaemia, insulin doses administered and the number of insulin injections required. If a high heterogeneity (I2>75%) was found, meta-regression was performed to identify the underlying reasons. The funder’s perspective was applied in the cost-minimization analysis by taking into account the cost of the drug and of medical devices necessary for its administration, based on the daily number of insulin injections. RESULTS - No further studies were found in addition to those included in a metaanalysis published by The Cochrane Library. On the basis of three eligible studies, insulin detemir was injected more frequently compared with glargine (weighted mean difference: 0.42 95% CI 0.14-0.69 injections/day). High heterogeneity was present in case of two endpoints: the incidence of overall hypoglycaemia per patient-year (I2=83%), and daily basal insulin dose in units per body weight (I2=94%). The reason for the high heterogeneity in hypoglycaemia rates was not identified by meta-regression; however, the difference in insulin doses per body weight was negatively associated with body weight (-0.027 IU/kg per 1 kg, 95%CI: -0.051; -0.004). On the basis of the present meta-analysis and meta-regression, our calculations suggest that treating an average weight (90 kg) patient with type 2 diabetes with insulin glargine would result in an annual cost reduction of 93 452 HUF compared with insulin detemir by employing gross public drug prices. CONCLUSION - On the basis of the available clinical evidence, insulin glargine might be a cost-saving alternative of insulin detemir in an average-weight patient with type 2 diabetes. In an era of scarce resources, the role of therapeutic alternatives offering cost savings with the same efficacy become more important. The generalisability of our conclusions might be influenced by potential differences in the manufacturers’ claw-back rate of detemir vs glargine insulin.]

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.

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.
