[Evaluation of mixed infusions in parenteral nutrition]


SEPTEMBER 25, 1991

Lege Artis Medicinae - 1991;1(15)

[The authors initiate a new method of parenteral nutrition. They evaluate the clinical utility of continuously mixed infusions. The infusion glasses are connected in a row with tubes, thus the solutions are mixed before entering the blood-vessels. To prove the regularity of the process and to detect the possible chemical changes, the substrate distribution and the pH was measured and a computer model of the process was created. The regularity of mixing was proven. The change of the pH was small, but for some components it was not ideal. The use of mixed infusions offers a mixed substrate pool, which is more physiological for the body. The authors suggest using mixed solutions for parenteral nutrition as one of the possibilities. ]

[On pulmonary tuberculosis]


[The author evaluates the epidemiological conditions of pulmonary tuberculosis in Hungary. The number of new cases decreases year after year. Being the disease infectious afterall, efforts must be continued against it adapted to the new epidemiological situation. This requires the collaboration of all the medical network systems as the pulmonological one is inefficient itself. Though the disease is rare, it cannot be forgotten and in certain cases tuberculosis must be borne in mind as well.]

[The differential diagnosis of pulmonary tuberculosis]


[Since the number of tuberculous patients is constantly decreasing, the diagnosis of pulmonary tuberculosis is a new challenge for physicians. That produces a lifethreatening danger specially for old tuberculous patients. Primary infection – since the clinical tuber culosis of children practically disappeared in Hungary - can be established mostly on young people with general symptoms, who's tuberculin-reaction shows hyperergy. The specific etiology of pleurisy can be determined by the exclusion of other etiologies on young tuberculin-positive people, but a thoracoscopic biopsy may be needed. Tuberculous bronchadenitis is a rarity, but must be differentiated from sarcoidosis or malignant mediastinal lymph nodes. In infiltrative lung diseases, primary and se condary pneumonias (caused in first line by lung cancer) and pulmonary infarctions are much more frequent, than tbc. The most difficult is the differential diagnosis of disseminated pulmonary diseases. The author warns against the too early application of aggressive diagnostic methods (BAL and especially lung biopsy by thoracotomy). He emphasizes in these situations the advantages of an antituberculous treatment without diagnosis (especially in old patients). In coin lesions the very specific transthoracic needle biopsy should be preferated. The author refers to the new researches objecting the rapid detection of BK in the sputum of paucibacillary patients, but is meaning, that the indirect ways of diagnosis mentioned in this paper would be necessary for a long time.]

[The importance of tuberculosis in childhood]


[Nowadays tuberculosis has already become a rare disease in childhood in Hungary but the danger of the infection is still present for the several thousand (over 3500) disease manifestations among adults. The main task of the pediatricians is prevention, however the disease should be borne in mind in case of unelucidated chronic cases. In suspicion of meningitis basilaris it is necessary to start the treatment at once. Until now the maintanence of the BCG vaccination by age groups (new-born, 11 and 18 years) was justified, but it needs further restriction due to the advance in epidemic situation.]

[Some problems and characteristics of pulmonary mycobacteriosis in hungary]

KOZMA Dezső, VINCZE Egon, DÁVID Sándor, KISHINDI Katalin, ALEXY György

[360 cases of pulmonary mycobacteriosis caused by atypical mycobacteria were observed between 1980 and 1989. M. xenopi proved to be the most frequent pathogen (in 67% of the cases) followed by M. kansasii and M. avium intracellulare. The disease was common in urban-industrial areas. The yearly incidence of disease has not been increased during the observed period. 86% of patients were male with the mean age of 55 years. Underlying diseases such as pulmonary tuberculosis and chronic obstructive lung disease were found frequently. The symptoms of the disease were uncharacteristic. Thin-wall cavities with the lack of an infiltrate appeared in 24% of the patients. Malignancy and pulmonary aspergillosis were the two more frequent concomitant diseases. The occurence of lung cancer and also other organ cancers were significant higher among these patients than in the normal population between 40–69 years of age. Findings of histopathology were indistinguishable from tuberculosis among M. kansasii cases. A relative lack of caseousiting necrosis, forced fibrosis, foreign body reaction and abortive granuloma formation appeared among M. xenopi and M. avium-intracellulare cases. ]

[An update on BCG vaccination]


[Tuberculosis is still a serious and wide-spread disease affecting mainly people living under poor hygienic conditions. Double infections with HIV + M. tuberculosis, however, may worsen the epidemiological situation both in developing and highly developed countries. Since its introduction, BCG vaccine has undergone several changes regarding the production strain and other characteristics. Though, the effectivity of BCG vaccination has been often questioned, it is indisputable that the vaccine protects young children against the disease. In Hungary, lyophilised „Paris" BCG strain has been safely and successfully used for vaccinating new-borns and revaccinating children for 30 years. The tbc incidence of the population under 14 years of age has been very low. Due to the relatively high tbc incidence among adults and the unfavourable tendency in the epidemiology of tbc in the world, however, no changes in the present BCG vaccination schedule are advisable. Moreover revaccination regardless to the tuberculin status should be considered. ]

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.

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.

Evaluation of the effectiveness of transforaminal epidural steroid injection in far lateral lumbar disc herniations

EVRAN Sevket, KATAR Salim

Far lateral lumbar disc herniations (FLDH) consist approximately 0.7-12% of all lumbar disc herniations. Compared to the more common central and paramedian lumbar disc herniations, they cause more severe and persistent radicular pain due to direct compression of the nerve root and dorsal root ganglion. In patients who do not respond to conservative treatments such as medical treatment and physical therapy, and have not developed neurological deficits, it is difficult to decide on surgical treatment because of the nerve root damage and spinal instability risk due to disruption of facet joint integrity. In this study, we aimed to evaluate the effect of transforaminal epidural steroid injection (TFESI) on the improvement of both pain control and functional capacity in patients with FLDH. A total of 37 patients who had radicular pain caused by far lateral disc herniation which is visible in their lumbar magnetic resonance imaging (MRI) scan, had no neurological deficit and did not respond to conservative treatment, were included the study. TFESI was applied to patients by preganglionic approach. Pre-treatment Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores of the patients were compared with the 3rd week, 3rd month and 6th month scores after the procedure. The mean initial VAS score was 8.63 ± 0.55, while it was 3.84 ± 1.66, 5.09 ± 0.85, 4.56 ± 1.66 at the 3rd week, 3rd month and 6th month controls, respectively. This decrease in the VAS score was found statistically significant (p = 0.001). ODI score with baseline mean value of 52.38 ± 6.84 was found to be 18.56 ± 4.95 at the 3rd week, 37.41 ± 14.1 at the 3rd month and 34.88 ± 14.33 at the 6th month. This downtrend of pa­tient’s ODI scores was found statistically significant (p = 0.001). This study has demonstrated that TFESI is an effective method for gaining increased functional capacity and pain control in the treatment of patients who are not suitable for surgical treatment with radicular complaints due to far lateral lumbar disc hernia.

Comparison of direct costs of percutaneous full-endoscopic interlaminar lumbar discectomy and microdiscectomy: Results from Turkey

ÜNSAL Ünlü Ülkün, ŞENTÜRK Salim

Microdiscectomy (MD) is a stan­dard technique for the surgical treatment of lumbar disc herniation (LDH). Uniportal percutaneous full-endoscopic in­terlaminar lumbar discectomy (PELD) is another surgical op­tion that has become popular owing to reports of shorter hos­pitalization and earlier functional recovery. There are very few articles analyzing the total costs of these two techniques. The purpose of this study was to compare total hospital costs among microdiscectomy (MD) and uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD). Forty patients aged between 22-70 years who underwent PELD or MD with different anesthesia techniques were divided into four groups: (i) PELD-local anesthesia (PELD-Local) (n=10), (ii) PELD-general anesthesia (PELD-General) (n=10), (iii) MD-spinal anesthesia (MD-Spinal) (n=10), (iv) MD-general anesthesia (MD-General) (n=10). Health care costs were defined as the sum of direct costs. Data were then analyzed based on anesthetic modality to produce a direct cost evaluation. Direct costs were compared statistically between MD and PELD groups. The sum of total costs was $1,249.50 in the PELD-Local group, $1,741.50 in the PELD-General group, $2,015.60 in the MD-Spinal group, and $2,348.70 in the MD-General group. The sum of total costs was higher in the MD-Spinal and MD-General groups than in the PELD-Local and PELD-General groups. The costs of surgical operation, surgical equipment, anesthesia (anesthetist’s costs), hospital stay, anesthetic drugs and materials, laboratory wor­kup, nur­sing care, and postoperative me­dication diffe­red significantly among the two main groups (PELD-MD) (p<0.01). This study demonstrated that PELD is less costly than MD.

[Operational Efficiency Investigation from APN Perioperative Perspective]


[In the healthcare system operating theatres have to put great emphasis on quality work, patient safety and efficiency as well, and to achieve this, optimal utilization of theatres is extremely important. The results of researches in this topic in Hungarian and international literature draw attention to a lot of aspects. The study of perioperative periods, and the evaluation of the analysed processes show that theatres could be operated more effectively. As a result of this, more operations could be carried out and waiting time would also reduce. In order to increase the efficiency of the processes, APNs can play a prominent role at several points. According to the experience, the number of people using health care and the number of people waiting for surgery is increasing, which is further increased by the development of the ongoing SARS-CoV-2 (COVID-19) epidemic. Thereby, patients are not satisfied with the service. The work of APNs would also help increasing the contentment of patients during the operation procedures. Taking advantage of the multifunctional role of the nurse due to her knowledge and training, she actively participates in the operation, in the smooth running of the scheduled daily surgical program and contributes to the reduction of the number of missed, planned surgeries.]
