[It can be concluded that the operator of quantitative electromyography must have considerable neurological experience, must be able to determine in which cases electromyography is necessary and which muscles should be examined in a given case. However, there is no doubt that the objective diagnostic value of the quantitative method of electromyography is also greater, albeit more costly and more work than the older, non-quantitative routine method that is more commonly used. ]

[Electroencephalographic studies in children with congenital vitium ]

RÁKOS György

[Electroencephalography was performed in 80 children with congenital vitium. Among 40 non-cyanotic, cardiac-compensated, clinically intact children with a clinically intact nervous system, only one with coarctation of the aortae was found to have an abnormality. Of 40 children with cyanotic congenital vitium, 13 were found to have cerebral lesions with eeg. No correlation was found between haematological data and eeg abnormality. A higher than average number of children with severe mental retardation and dyspnoea with sudden onset of hypoxia and cyanotic seizures with cyanotic seizures differed from the average. ]

[Alcoholism issues in a village life]


[In 1961, a village of 629 inhabitants consumed 500 000 HUF worth of alcoholic beverages. One individual spent more than 2 HUF per day for the total population and more than 6 HUF per day for the adult male population, which represents 12 and 36% of the total income per person respectively. 17 chronic alcoholics are from the better-off and more culturally demanding population of the village. The fight against alcoholism can be tackled by expanding cultural leisure activities, by creating a tax-efficient culture and by certain practical measures. ]

[About the neurological causes of difficulty passing urine]


[Some authors recognise a disease in which neither a neurological cause nor a local cause (inflammation of the sphincter or bladder neck or mechanical obstruction to urine emptying) can be identified, but urine emptying is probably obstructed by an overweight of the orifice intimal muscles. This is suggested by the recognition that these conditions can also be resolved by resection of the bladder neck.]

[Cerebrospinal fluid hypotension associated with vaso-anoxic cerebral damage]


[The authors present the case of a 47-year-old male patient who developed aliquorrhoea and severe apallium syndrome in the setting of fever (presumably influenza); the disease was cured without residual symptoms after antibiotic treatment and intrathecal and parenteral fluid therapy. Based on analysis of the clinical data, it is considered likely that both the aliquorrhoea and the neurological symptoms were the consequence of a disturbance of the intracranial circulation. In their case, the authors put forward their hypothesis that the pathomechanism of CSF hypotensive syndromes is due to circulatory dysfunction and secondary reflexes induced by a decrease in CSF pressure, which feed back to the cerebral and plexus circulation.]

Sandhoff disease is a rare type of hereditary (autosomal recessive) GM2-gangliosidosis, which is caused by mutation of the HEXB gene. Disruption of the β subunit of the hexosaminidase (Hex) enzyme affects the function of both the Hex-A and Hex-B isoforms. The severity and the age of onset of the disease (infantile or classic; juvenile; adult) depends on the residual activity of the enzyme. The late-onset form is characterized by diverse symptomatology, comprising motor neuron disease, ataxia, tremor, dystonia, psychiatric symptoms and neuropathy. A 36-year-old female patient has been presenting progressive, symmetrical lower limb weakness for 9 years. Detailed neurological examination revealed mild symmetrical weakness in the hip flexors without the involvement of other muscle groups. The patellar reflex was decreased on both sides. Laboratory tests showed no relevant alteration and routine electroencephalography and brain MRI were normal. Nerve conduction studies and electromyography revealed alterations corresponding to sensory neuropathy. Muscle biopsy demonstrated signs of mild neurogenic lesion. Her younger brother (32-year-old) was observed with similar symptoms. Detailed genetic study detected a known pathogenic missense mutation and a 15,088 base pair long known pathogenic deletion in the HEXB gene (NM_000521.4:c.1417G>A; NM_000521:c.-376-5836_669+1473del; double heterozygous state). Segregation analysis and hexosaminidase enzyme assay of the family further confirmed the diagnosis of late-onset Sandhoff disease. The purpose of this case report is to draw attention to the significance of late-onset Sandhoff disease amongst disorders presenting with proximal predominant symmetric lower limb muscle weakness in adulthood.

[Assessing Nurses’ Knowledge of Surgical Wound Care, Complications and Knowledge of Bandages]


[Aim of our research was to assess the knowledge of nurses working in surgical departments about surgical wound treatment, phases of wound healing, its complications, and intelligent bandages. Our quantitative, cross-sectional, descriptive examination was carried out in a hospital in Transdanubia with non-random, expert sampling and a self-made questionnaire. Our target group was nurses working in the surgical departments of the hospital (N=85). During the data analysis, the descriptive statistical methods of MS Office Excel 2016 software were calculated: mean, standard deviation, frequency. A χ2-test was used to examine the relationship between variables (p <0.05). Knowledge of bandages was not affected by educational attainment (p>0.05). Those who perform wound care in their daily work have more knowledge about the wound treatment sequence of the wounds that are primarily healing, as well as about intelligent dressings (p<0.1). For the classes, there was a significance for the recognition of complicated wounds, knowledge of the benefit of the absorbable suture and the use of analgesic procedures (p<0.001). In the interests of patient safety, nurses’ knowledge of wound treatment needs to be continuously improved. It is necessary to provide an accessible source of information and further training.]

[Assessing Quality of life of Women with Cervical Cancer After Treatment]


[To assess sexual function, functionality and quality of life in women with cervical cancer. Descriptive, cross-sectional, quantitative, non-random, purposive sampling of women (N=91) with FIGO stage I/II/III cervical cancer, more than 5 months after last treatment. The study used standard questionnaires with self-designed questions. Data were analysed using Microsoft Excel, descriptive and mathematical statistics (p<0.05). Completers who received radiotherapy scored significantly higher in functional status (p<0.05) and emotional function than those who did not receive radiotherapy (p<0.05). Completers with lower levels of emotional well-being were significantly more likely to have lower levels of sexual function and higher levels of gynaecological problems (p<0.05). Women affected by cervical cancer often experience somatic and psychological disturbances that reflect on quality of life associated with the disease and treatment.]

[Evaluation of clinical practices among academic nursing students]


[Purpose: Establishing a balance between theoretical and practical training is essential in the training of college nursing students. The aim was to assess the students’ experiences of clinical practice and the problems they indicate in the component, which plays an important role in preparing the training for professional competencies. The study sample consisted of 3rd and 4th grade students (N=96) participating in nursing training at the Faculty of Health Sciences of Semmelweis University. The method of data collection was based on the completion of a quantitative online questionnaire, which also included qualitative elements in the form of three open-ended questions. Among the statements measured on the Likert scale, the balance of theory-practice, the role of participants in education, and the time spent on practical tasks received lower average ranks from both grades. Logistic regression is suitable for estimating the probability of a positive/negative impression of a practice as a combined effect of several explanatory variables. Compared to the results of a previous (2009) study, the problems with field clinical training remain unresolved.]

[Identifying osteoporosis in a primary care setting with quantitative ultrasound]

HIRDI Henriett Éva, SZOBOTA Lívia

[Osteoporosis is one of the most under-diagnosed and under-treated health conditions. In recent decades, several risk indices have been developed to identify women at risk for low bone mineral density (BMD) who require a BMD test. This study aimed to demonstrate that quantitative ultrasound bone density measurement can indeed be performed simply by nurses working in primary care, which can significantly facilitate early detection of osteopenic and osteoporotic conditions. Method: The medical records of all patients who had an ultrasound of the left heel using the quantitative heel ultrasound machine between March 2021 through December 2021 were reviewed retrospectively. The subjects were 20-64-year-old adults (N=1032). Calcaneal quantitative ultra­sound parameters were registered with Sonost-2000 bone densitometer. The body composition was measured using a multi-frequency segmental body composition analyzer. The measurement results were evaluated with SPSS 22.0 statistical program and descriptive statistics. The mean age of the population studied was 43.12±9.6 years; 29.7% were men and 70.3% were women. Of the women in our study, 2.4% were osteoporotic (T ≤ −2.5), and 49.86% were classified as osteopenic according to the WHO operational definition. Osteopenic values were measured in 32.35% of men. A total of 273 subjects (26.45%) in the study sample were in the 50-64 age group (223 women and 50 men). 4% of women over the age of 50 had osteoporosis and 63.7% had osteopenia. Rating of the OST score no one was placed in the high-risk group. Of the 9 women with osteoporosis, 8 were classified as low-risk and 1 as medium based on OST. Nurses in primary care are able to identify key risk factors for osteoporosis, examine the measurement with quantitative ultrasound, and identify individuals with the disease. ]
