Introduction. Although well protected, brain is not resistant to infection agents. Acute infections of our nervous system appear more often in children and in persons who have medical history data about previous disorders, especially disorders of the nervous system. It is difficult to list possible risk factors which can be responsible for the appearance of infections of CNS and the resulting conditions. It is often difficult or impossible to determine what previous neural damage was (trauma, anoxic damages etc.) from those appearing during infections of CNS. All-inclusive anamnestic research reduces the possibility of approximate judgments. Material and methods. The research was based on the retrospective analysis of medical documentation of 275 patients. All patients were divided into three groups according to the final diagnosis. The first group consisted of 125 patients who were treated for acute virus encephalitis, the second group consisted of 125 patients who were treated for acute bacterial meningoencephalitis and the third group consisted of 25 patients who were treated for cerebritis. Discussion. In our studies sample, the youngest patient was 3 years old and the oldest was 87 years old. The highest number of patients with virus infection of the CNS was in the group under 25 years of age (45.6%). The highest number of patients with bacterial infections of the CNS and cerebritis was in the group of patients over 45 years of age (64%, 37%). Conclusion. Risk factors were more present in bacterial infections of the nervous system and cerebrit thanin virus infection of CNS. In virus infections of the CNS, 28% of patients had some risk factor, most often-chronic ethylism, diabetes mellitus and acquired heart diseases. In bacterial infections of the CNS, 64% of patients had some predisposed factor. The most frequent factor of risk in these patients were chronic otitis (21.6%) and craniotrauma (14.4%). In cerebritis, risk factors were present in 76% of patients and they were: sepsis (20%), chronic otitis (12%) and systemic lupus erythematosus (8%).

Background/Aim. Etiology of ischemic stroke (IS) among young adults varies among countries. The aim of the study was to investigate the causes and risk factors of IS in the young adults of Serbia. Methods. A total of 865 patients with IS, aged 15 to 45 years, were treated throughout the period 1989-2005. Etiologic diagnostic tests were performed on the patient by the patient basis and according to their availability at the time of investigation. The most likely cause of stroke was categorized according to the TOAST (Trial of ORG 10172 in Acute Stroke Treatment) criteria. Results. There were 486 men and 379 women, with 19% of the patients ? 30 years old. Large artery arteriosclerosis and small artery disease were confirmed in 14% of the patients, and embolism and other determined causes in 20%. Undetermined causes made up 32% of the patients, mostly those (26%) with incomplete investigations. Smoking (37%), hypertension (35%) and hyperlipidemia (35%) were the most common risk factors. Rheumatic heart diseases and prosthetic valves were the most common causes of IS. Arterial dissections and coagulation inhibitors deficiency were detected in a small number of patients. Conclusion. Etiology of IS among Serbian young adults shares characteristics of those in both western and less developed countries.

Objectives: Stroke is a significant public health problem and one of the important preventable non-communicable diseases. Preventive stroke programs are yet to be properly established in Oman, with a better focus on increasing awareness among those who are currently at risk. This study was conducted to describe the characteristics of stroke presenting to a tertiary care hospital in Oman. Methods: This was a cross-sectional hospital-based study. Included 193 stroke cases which were prospectively recruited from the Emergency Department of a tertiary-level hospital. Data was collected from November 2017 to April 2018. Results: The total number of patients was 193. 82.9% of strokes were ischemic strokes. 58% were male. The mean age of stroke patients was 61.05 years. Risk factors included hypertension (72.5%) and diabetes mellitus (54.4%). Dyslipidemia, atrial fibrillation and ischemic heart diseases were not particularly prevalent in our population. 24.4% of ischemic strokes had large artery atherosclerosis and 21.9% had small vessel occlusion. Significantly more patients had lower Glasgow Coma Scale (GCS), required ICU admission and had in-hospital deaths in hemorrhagic stroke compared to ischemic stroke. Conclusions: This study provides essential stroke characteristics data specific to Oman’s population. Most of the information obtained conforms with that described internationally and similar preventive strategies can be implemented. The information can be utilized by health administrators in planning resource allocation. Further research is needed to explore rehabilitation aspects and long-term outcomes.

Objective: to study and analyze the dynamics of prevalence, demographic, social, and clinical manifestations of systemic lupus erythematosus (SLE) in patients living in Kazakhstan.Materials and methods. Official materials of the Ministry of Health of the Republic of Kazakhstan (2009–2018): statistical compendiums, a consolidated reporting form for medical treatment (N 12). 102 patients (100 women and 2 men) were included in the register of SLE with reliable SLE according to SLICC (ACR, 2012). Assessment of the debut of the disease was carried out according to archival material (medical history, outpatient records) of patients. The activity of the process was evaluated according to SLEDAI-2K, organ damage according to SLICC/ACR (2000).Results. The total number of patients with SLE over 10 years (2009–2018) more than doubled, the growth rate was 101%. The overwhelming majority of patients with SLE are women (91%). In the study group, Asians (83.33%) predominated by race, of which Kazakhs (76.47%) were young (mean age – 33.85±10.58 years), with a disease duration of 5 (2; 9) years, time from the appearance of the first signs to verification of SLE – 4.5 (3; 12) years. The prevailing acute (49.0%), subacute (33.3%), rather than chronic (18.7%) variants of the course, with high activity according to SLEDAI-2K – 17.64±8.80. The most common clinical manifestations of the disease: skin lesions (98%), joints (79.4%), nervous system (49%), hematological (54.9%) and immunological (100%) disorders. The absence of organ damage (0 points) was detected in 10 (9.8%) cases, low (1 point) – in 21 (20.6%), medium (2–4) – in 61 (59.8%), high (over 4) – in 10 (9.8%) patients.Conclusion. SLE remains a socially significant disease in Kazakhstan, as evidenced by the dynamics of the increase in incidence (101%) over 10 years (2009–2018). The prevalence of SLE is 24.7 per 100 thousand of the country’s population, lower than in other countries with a predominant Asian population or in comparison with Asian populations. A cohort of patients with SLE was represented by people of the Asian race (83.33%), Kazakhs (76.47%), and young people (33.85±10.58). The analysis revealed a delayed verification of the diagnosis of SLE (on average 4.5 (3; 12) years). Acute variants of the course of the disease with high disease activity according to SLEDAI-2K prevail. Common clinical manifestations of SLE are skin lesions, both acute and chronic (98%), joints (79.4%), damage to the nervous system (49%), hematological (54.9%) and immunological disorders (100%).

The Relationship

Introduction: The Zika virus (ZIKV) is an arbovirus of RNA, whose transmission is mainly vector - by mosquitoes of the genus Aedes - but it also occurs through sexual, blood and transplacental transmission, with the last mentioned it was possible to verify serious neurological effects in the epidemic in South America, especially in Brazil, between 2015 and 2016. Objectives: To analyze the relationship between Zika virus infection and microcephaly in recent scientific literature. Methodology: Refers to a bibliographic review in the databases SciELO, LILACS and MEDLINE / Pubmed, with the terms “zika virus”, “infection” and “microcephaly” correlated in Portuguese and in English; 78 articles were found, but only 7 followed for analysis. Articles published more than 5 years ago and out of the proposed theme were disregarded. Results: The Zika virus, although similar to the dengue and chikungunya virus, it has a tendency to cause damage to the central nervous system such as Guillain-Barré Syndrome. However, the association between microcephaly and ZIKV started to be more observed through the increase of the disease among fetuses and newborns of mothers who had been infected during the gestational phase in the epidemic that happened in Brazil. It is known that the development of the nervous system is the product of processes of high proliferation and cellular differentiation, in which even small errors generate dangerous impacts, and it is during this period that ZIKV affects the CNS of the fetus. The disease is characterized by the reduction of the brain perimeter, in this context, is a consequence of abnormalities influenced by the virus. Conclusions: Microcephaly is a complex disease; therefore, it is necessary to emphasize the importance of primary care and other spheres for monitoring Zika virus infections, prenatal care and constant psychosocial monitoring. Furthermore, it is necessary to understand the relevance of studies about ZIKV and microcephaly, and to encourage scientific production in this area.

Abstract Background Central nervous system (CNS) infections are relatively rare but are associated with high mortality worldwide. Empirical antimicrobial therapy is crucial for the survival of patients with CNS infections, and should be based on the knowledge of the pathogen distribution and antibiotic sensitivities. The aim of this study was to investigate the features of pathogens in patients with CNS infections in North China and evaluate the risk factors for mortality and multi-drug-resistant (MDR) bacterial infections. Methods A retrospective study was conducted with patients with positive cerebrospinal fluid (CSF) cultures in a teaching hospital from January 2012 to December 2019. The following data were collected: demographic characteristics, laboratory data, causative organisms and antimicrobial sensitivity results. Data were analyzed with SPSS 16.0. Univariate analysis and binary logistic regression analyses were performed to identify the risk factors for mortality and MDR bacterial infections. Results A total of 72 patients were diagnosed with CNS infections, and 86 isolates were identified. The proportions of Gram-positive bacteria, Gram-negative bacteria and fungi were 59.3, 30.2 and 10.5%, respectively. The predominant Gram-positive bacteria was Coagulase-negative Staphylococci. Acinetobacter baumannii, Escherichia coli and Klebsiella spp. were the predominant Gram-negative bacteria. Compared to 2012–2015 years, the proportion of Gram-negative bacteria increased markedly during 2016–2019 years. Coagulase-negative Staphylococci, Streptococcus pneumoniae and Enterococcus faecium had 100% sensitivity to vancomycin, teicoplanin and linezolid. Acinetobacter baumannii and Klebsiella pneumoniae were 100% sensitive to tigecycline. Escherichia coli had 100% sensitivity to amikacin, meropenem and imipenem. The overall mortality rate in the 72 patients was 30.6%. In multivariate analysis, age > 50 years, pulmonary infections and CSF glucose level < the normal value were associated with poor outcomes. CSF adenosine deaminase level > the normal value and the presence of external ventricular drainage/lumbar cistern drainage were associated with MDR bacterial infections. Conclusions The mortality rate due to CNS infections reached 30.6% in our study. The proportion of Gram-negative bacteria has increased markedly in recent years. We should give particular attention to patients with risk factors for mortality and MDR bacterial infections mentioned above.

Summary 99mTc tin colloid accumulated in the lungs in 102 patients during liver imaging both in malignant and benign diseases. The percentage of neoplastic diseases increased when the lung uptake became greater and only patients with malignant final diagnosis had marked lung uptake. Abnormal liver image was seen only in 23%, which disagrees highly with some earlier findings on a rather small number of patients. The cause of increased lung uptake was suggested to be the activation of the reticuloendothelial system (RES) by disease. The activation of the RES was stronger in malignant than in benign diseases. Some type of regional stimulation of the RES was suggested as being due to the location of the disease and both malignant and benign diseases of the chest region stimulated the pulmonary part of the RES more than other parts of the RES.
