[Results obtained by pulsed electromagnetic field therapy in delayed healing or pseudoarthrosis of various fractures]

KRICSFALUSY Mihály, UDVARDY Csaba, LITVAI Gabriella

[INTRODUCTION - Delayed healing or the development of pseudoarthrosis after a conservatively or surgically treated fracture significantly prolongs the time of patient recovery and rehabilitation.The aim of the study was to investigate the influence of pulsed electromagnetic field (PEMF) therapy on delayed fracture healing or pseudoarthrosis in fractures of various long bones. PATIENTS AND METHODS - Twenty-one patients with abnormal fracture healing were treated ambulatorily a mean of 8.7 months after the injury with PEMF by a Biostim device (IGEA, Italy) for a mean of seven weeks. RESULTS - Overall, fracture healing was established in 15 patients, which corresponds to a recovery rate of 71.4%. By excluding the two patients, however, in whom bone restoration was inhibited by mechanical factors, healing rate increases to 78.9%. Pain intensity decreased substantially; function and endurance of the limb improved in every patient. CONCLUSIONS - These results as well as international data justify the need for wide-spread application of biophysical bone healing enhancement methods in Hungary, the first step of which is to popularize it among clinicians.]

[Percutaneous vertebroplasty in the treatment of osteoporotic vertebral compression fractures]

KULCSÁR Zsolt, SZIKORA István, BERENTEI Zsolt, MARTOS János, NYÁRY István

[Percutaneous vertebroplasty is a minimally invasive procedure that is increasingly applied for the treatment of osteoporotic compression fractures. The authors discuss its indications, patient selection criteria, the issue of diagnostic imaging, the technique of the procedure, its potential complications, review the literature on post-procedure pain relief, and briefly present their own experience in the treatment of osteoporotic fractures. Vertebroplasty is indicated for patients with severe, persistent, often incapacitating focal back pain not responding to standard medical therapy, which is related to the collapse of one or more vertebral bodies. Patients selected carefully by the clinical symptoms and the imaging studies usually respond promptly to the treatment, experience significant pain relief, improvement of the quality of life, and an increase in mobility.Vertebroplasty is a safe procedure with relatively low complication rates.The potential neurological complications, however, necessitate an instantly available neurosurgical background.]

TÓTH EDIT, CSUPOR EMŐKE, MÉSZÁROS SZILVIA, FERENCZ VIKTÓRIA, NÉMETH Lóránd, VARGHA Péter, HORVÁTH CSABA

[INTRODUCTION -The aim of this study was to examine the effect of intranasal salmon calcitonin therapy on bone mineral density in idiopathic male osteoporosis without vertebral fractures. MATERIALS - The randomised, prospective, controlled trial involved 71 male patients (mean age 59±6 years) suffering from idiopathic osteoporosis (lumbal spine and femoral neck T-score <-2.5) without vertebral deformity. Study design: Treatment protocol: Patients in the control group (n=31) received 400 IU Vitamin D + 1000 mg elemental calcium daily while the treatment group (n=40) received 400 IU Vitamin D, 1000 mg elemental calcium and 200 IU calcitonin nasal spray daily, by an intermittent monthly dose. METHODS - 1. Osteodensitometry: lumbar spine (L2-4) and femoral neck were measured by dual photon absorptiometry (LUNAR DPX-L, USA), whereas non-dominant radius was measured by single photon absorptiometry (NK 364, Gamma, Hungary). 2. Roentgenomorphorphometry was done onthoracic IV to lumbar IV spines and deformity indeces were calculated. The treatment period was 18 months. Examinations were performed at baseline and at the end of treatment.The primary end-point was the change of bone density measured by osteodensitometry. Secondary end-points included the side effects of medication. RESULTS - Nasal calcitonin was associated with significant increase in bone mineral density at the lumbar spine (+3.5±4.3% vs. +0.83±6.4%, p=0.04) and the femoral neck (+3.2±3.9% vs. -0.68±5.7%, p=0.004). No significant difference was observed at the radius between the treatment groups (+1.4±8.8% vs. +1.4±10.9%, p=0.98). No osteoporotic fractures occurred in the treated group, but there were 3 fractures in the control group. Treatment was well tolerated with no premature discontinuations nor significant side effects compared to the control group. CONCLUSION - 200 IU salmon calcitonin nasal spray used daily, intermittently proved to be an effective and safe therapy in male idiopathic osteoporosis.]

Fluoxetine use is associated with improved survival of patients with COVID-19 pneumonia: A retrospective case-control study

NÉMETH Klára Zsófia, SZÛCS Anna , VITRAI József , JUHÁSZ Dóra , NÉMETH Pál János , HOLLÓ András

We aimed to investigate the association between fluoxetine use and the survival of hospitalised coronavirus disease (COVID-19) pneumonia patients. This retrospective case-control study used data extracted from the medical records of adult patients hospitalised with moderate or severe COVID-19 pneumonia at the Uzsoki Teaching Hospital of the Semmelweis University in Budapest, Hungary between 17 March and 22 April 2021. As a part of standard medical treatment, patients received anti-COVID-19 therapies as favipiravir, remdesivir, baricitinib or a combination of these drugs; and 110 of them received 20 mg fluoxetine capsules once daily as an adjuvant medication. Multivariable logistic regression was used to evaluate the association between fluoxetine use and mortality. For excluding a fluoxetine-selection bias potentially influencing our results, we compared baseline prognostic markers in the two groups treated versus not treated with fluoxetine. Out of the 269 participants, 205 (76.2%) survived and 64 (23.8%) died between days 2 and 28 after hospitalisation. Greater age (OR [95% CI] 1.08 [1.05–1.11], p<0.001), radiographic severity based on chest X-ray (OR [95% CI] 2.03 [1.27–3.25], p=0.003) and higher score of shortened National Early Warning Score (sNEWS) (OR [95% CI] 1.20 [1.01-1.43], p=0.04) were associated with higher mortality. Fluoxetine use was associated with an important (70%) decrease of mortality (OR [95% CI] 0.33 [0.16–0.68], p=0.002) compared to the non-fluoxetine group. Age, gender, LDH, CRP, and D-dimer levels, sNEWS, Chest X-ray score did not show statistical difference between the fluoxetine and non-fluoxetine groups supporting the reliability of our finding. Provisional to confirmation in randomised controlled studies, fluoxetine may be a potent treatment increasing the survival for COVID-19 pneumonia.

Cases of inborn errors of metabolism diagnosed in children with autism

CAKAR Emel Nafiye, YILMAZBAS Pınar

Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.

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.

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.

[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 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. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]
