[The two types of endoscopes presently available for examination and treatment of the esophagus are the traditional open tube esophagoscope and the flexible endoscope. Despite the many advantages offered by the flexible endoscope, its limitations should not be forgotten. The open tube esophagoscope should not be thought of as out-of-date, since its new variations have important therapeutic applications. The authors examine the advantages and disadvantages of the two types of esophagoscopes as discussed in the literature. ]

[Ultrasonic signs of suspected fetal chromosomal aberration]

ÁDÁM Zsolt, NÉMET János, SZABÓ István, CSABAY László, TÓTH-PÁL Ernő, HAJDÚ Júlia

[The authors summarize the relevant ultrasonic findings in case of suspected fetal chromosomal aberration. Some of these signs are detectable during routine ultrasonic screening examinations. In high-risk cases, prenatal chromosomal analysis is recommended. The following ultrasonic findings indicate a situation of high risk: disturbances of the lymphatic and amniotic fluids (e.g. hydrops, hygroma colli, polyhydramnios, nuchal edema), certain skull and brain alternations, abnormalities of the thorax and abdomen, and „minor” findings such as a single umbilical artery, choroid plexus cyst, pyelectasy, or changes in the size or shape of the long tubular bones, if these signs are accompanied by other anomalies or growth retardation.]

[An update on obstructive sleep apnea]

METES Ágnes, HIRSCHBERG Andor

[Obstructive sleep apnea, which occurs in approximately 2% of the adult population, is the more common of the two major forms of sleep apnea. The conse quences and dangers of excessive daytime sleepiness are emphasized along with the other well-known characteristics of sleep apnea syndrome. Both the decreased upper airway muscle tone during sleep and the negative pressure due to breathing through the obstructed airways may cause upper air ways to collapse. The history has a very important role in the clinical assessment, while the role of the physical examination is limited. An exact and reliable diagnosis may be arrived at through laboratory evaluation, e. g. polysomnography (PSG), Multiple Sleep Latency Test (MSLT), or radiologic examinations. Among conservative treatments, reduction of the body weight is usually effective in mild to moderate cases. In severe apneas, nasal continuous positive airway pressure (nCPAP) is the current treatment of choice. The efficacy of surgical intervention is still controversial. According to most authors, uvulopalatopharyngoplasty (UPPP) has a 50% success rate. Most recently good results have been obtained with maxillo-facial surgery in a variety of selected patients. ]

[The role of echocardiography in the management of ventricular free wall rupture ]

PÁL Mátyás, LENGYEL Mária

[Our goal was to evaluate which diagnostic and therapeutic approaches could provide a better chance of survival. Between January 1, 1987, and December 7, 1992, 772 patients with acute myocardial infarction were treated in the Hungarian Institute of Cardiology. Cardiac rupture was investigated by the retrospective analysis of clinical data, electrome chanical dissociation, echocardiographic signs and autopsy findings. Ventricular free wall rupture was found in 28 cases. The diagnosis was confirmed by autopsy in 23, by intraoperative findings in 4 cases, and by echocardiography and pericardiocentesis in 1 case. Pericardial effusion was detected in 12 of 14 cases undergoing emergency echocardiography. Seven of these had pericardiocentesis and 2 patients underwent surgical pericardial fenestration. Following this 4 patients were referred to surgery. All 4 patients died: 2 during and 2 shortly after operation. The bleeding stopped in 1 case, after pericardiocen tesis and continous drainage and during the 12 month follow-up the patient is alive and well. In acute myocardial infarction, electromechanical dissociation or signs of tamponade are indications for emergency echocardiography, and if pericardial effusion can be visualized, pericardiocentesis should be performed. This can lead to a temporary haemodynamic improvement, providing sufficient time for emergency surgery.]

[Rapid photocopy documentation of histological speciments]

KISS Ferenc, CSABA Andrea, KELLEI Ilona, CSELLÁR Mihály, SZERDAHELYI Andrea

[A simple photocopy technique for histological slide preparations of surgically removed specimens is described. Standard office copy machines may be used for this method which is faster than traditional photography and cheaper than polaroid technique. Significant information is quickly provided by the copies for both the physician and the pathologist, including location and extent of the lesion, the state of its neighbouring structures and the resection margins. Retrospective identification of the tissue sections chosen for histological investigation is also facilitated. Despite some technical limitations, this copy technique may effectively support the diagnostic work of the surgical pathologist.]

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.
