Shigellosis results in considerable morbidity in endemic areas, but mortality is rare in developed countries. All pediatric deaths (n = 15) in Israel following shigellosis in the past 10 years were reviewed. The patients' ages ranged from 5 months to 11 years; there were eight boys and seven girls. Three were institutionalized mentally retarded patients, 11 were healthy children. Twelve had definite clinical signs of brain death within 48 hours of onset of disease. Cause of death in all patients was consistent with toxic encephalopathy. No other systemic complication was implicated as the cause of death except for one case consistent with a "Reye-like" syndrome. Shigella species were as follows: 8 flexneri, 4 sonnei, 1 dysenteriae, and 2 were not identified. Case-control study of these patients vs surviving, hospitalized patients with shigellosis showed similar severity of fever, diarrhea, vomiting, and dehydration and similar incidence of convulsions. Headache was a prominent feature of patients who died; 5 of 7 verbal patients complained of this symptom as opposed to 2 of 20 in the control group (P < .01). There were no significant differences in the hematological and biochemical profile (except for an increased incidence of hyponatremia in the study group), pattern of shigella species, or antibiotic sensitivity. These findings indicate that mortality from shigellosis in a developed country is due primarily to the toxic encephalopathy syndrome.

Introduction Acute appendicitis is the most common reason for emergency abdominal surgery in the pediatric population. Ultrasound (US) is a widely used modality to diagnose acute appendicitis. The aim of this study was to evaluate the effectiveness of portal vein diameter and flow velocity in acute appendicitis diagnosis. Methods Portal vein diameter and flow velocity were measured in children who were referred to radiology with a clinical diagnosis of acute appendicitis. The largest appendix diameter and leukocyte count of the patients were recorded. A control group was created which consisted of healthy children, and their portal vein diameter and flow velocities were also measured. Results The median age of the population was 10 years (range, 3–17 years). Mean portal vein diameter was 7.53 ± 1.55 mm in the control group, 7.92 ± 1.88 mm in the other diagnosis group, and 8.76 ± 1.91 mm in the acute appendicitis group. Mean portal vein diameter was significantly higher in the acute appendicitis group (p = 0.001). Median portal vein flow velocity was 17 cm/s (10–29 cm/s) in the control group, 18.3 cm/s (8–27 cm/s) in the other diagnosis group, and 20.5 cm/s in the acute appendicitis group. Median portal vein flow velocity was significantly higher in the acute appendicitis group (p = 0.00). Conclusion Detecting an increase in portal vein diameter and/or flow velocity in equivocal cases may support other clinical signs associated with acute appendicitis. Portal vein diameter and flow velocity can serve as additional diagnostic markers in acute appendicitis cases.

Abstract Background Short bowel syndrome (SBS) is defined as the a malabsorptive condition most often caused by massive resection of the small intestine. In children most cases of SBS originate in the newborn period and result from congenital anomalies or necrotizing enterocolitis. Loss of gut mucosa during resection does not only mean loss of absorption surface, but also deprives organism of many immunocompetent cells concentrated in gut associated lymphoid tissue, which is regarded the largest immune organ in humans. Aim of the study: We have aimed to access the influence of bowel resection on adaptive immunity in children, basing on peripheral lymphocyte populations and serum immunoglobulins. Patients and methods: 18 children, who underwent bowel resection in the first month of life and required further home parenteral nutrition were enrolled into the study. 12 healthy children, constituted control group. Based on flow cytometry the following subpopulations of lymphocytes were evaluated: T, B, NK, CD4+, C8 + and activated T cells. Serum immunoglobulins were determined with the use of immunoturbidimetric method. Results The percentage of B lymphocytes was reduced, while the rates of lymphocytes T and CD8 + lymphocytes were higher compared to healthy children. We documented significantly lower absolute count and proportion of NK cells in SBS group than in the control group. Absolute counts of lymphocytes, lymphocytes B, T, CD4 + and percentages of lymphocytes CD4+, and activated T cells inversely correlated with the time after resection. No statistically significant differences were found between the levels of IgA, IgM and IgG in the studied and the control group Conclusions Children with SBS do not present with clinical signs of immunodeficiency as well as deficits in peripheral lymphocyte populations and serum immunoglobulins. Lower number of NK cells in SBS patients compared to healthy children needs to be verified in larger cohort. The tendency of the lymphocyte subpopulations to decrease over time after resection points out the necessity for longer follow- up.

Endogenous intoxication syndrome is one of the leading syndromes in high urinary system infection activity in children. The study of clinical and laboratory manifestations of endogenous intoxication syndrome with the aim of optimizing its methods of therapy is topical. The examination was conducted in 52 children aged 3–7 years, including 22 children with active forms of pyelonephritis and 30 almost healthy children (control group). Endogenous intoxication syndrome was determined by clinical signs and by the level of leukocyte index of intoxication and medium-sized molecular peptides in blood plasma. Statistical analysis was carried out on the basis of Student’s t-test (p<0.05), the frequency of symptom occurrence (q) in relation to the totality in the group taken for 1 and the coefficients (Q) of the ratio of the comparable indicators in groups. In the control group, the leukocyte intoxication index did not exceed 1.0, the average molecular peptides— 0.24 conditional units. Most patients (q-0.73) had a moderately severe course, expressed symptoms of intoxication, pain abdominal syndrome (q-0.73), dysuria (q-0.73), high temperature (q-0.73). In complex therapy, prebiotic (complex fructoolygosaccharides, inulin and maltodextrin) was prescribed in age dosage for three weeks. Detoxification therapy contributed, first of all, to the positive dynamics of clinical manifestations of the intoxication syndrome. During the first two days, the temperature reaction decreased; on the 4-5th day, the general condition improved, other symptoms of intoxication disappeared; highly reliable (p<0.001) positive changes in the studied indicators were found within 3 weeks. They were characterized by the normalization of the level of leukocyte index of intoxication and medium-sized molecular peptides, which justifies the use of prebiotic products in the complex therapy of urinary system infection in children.

Introduction. The problem of congenital chlamydial infection is still remaining relevant due to the difficulties in its diagnosis and peculiarities of the course. The aim of this study was to clarify the dynamics of the severity and nature of the affection of the central nervous system in the case of congenital chlamydial infection. Materials and methods. 103 newborns were examined. Catamnestic observations were performed during a year. Specific diagnosis was made by polymerase chain reaction with the detection of chlamydia DNA in the blood serum of newborns. The main group included 80 children; the second control group consisted of 23 healthy children. The group III involved 36 children assessed as having satisfactory health status at birth, whose mothers had Chlamydia infection. Results and discussion. Analysis of the results showed that visceral forms with congenital chlamydial pneumonia were diagnosed in almost 50% of newborns; localized forms (congenital conjunctivitis) were diagnosed in 7.5% of children. 45% of newborns of the main group had no clinical signs of the disease. Neurosonography was performed in dynamics. It demonstrated that lenticular vasculopathy, areas of increased echogenicity, thickening of the ventricular walls, both alone and in combination were found only in the children of the main group and could be regarded as markers of intrauterine infection. Neurosonographic examination during the 1 year of life of the children in the main group indicated the presence of pathological changes. In the children of the control group markers of intrauterine infection were not detected. Thus, the obtained neurosonographic data confirm the long-term and damaging effects of chlamidia infection in the children of the main group. Conclusion. Pathological changes detected by neurosonography persisted during the first year of life and correlated with the formation of stato-kinetic developmental delay, muscular dystonia syndrome, and cerebral palsy in children.

Enteroaggregative Escherichia coli (EAEC) is an evolving enteric pathogen that causes acute and chronic diarrhea in developed and industrialized nations in children. EAEC epidemiology and the importance of atypical EAEC (aEAEC) isolation in childhood diarrhea are not well documented in the Indian setting. A comparative analysis was undertaken to evaluate virulence, phylogeny, and antibiotic sensitivity among typical tEAEC versus aEAEC. A total of 171 EAEC isolates were extracted from a broad surveillance sample of diarrheal (N = 1210) and healthy children (N = 550) across North India. Polymerase chain reaction (PCR) for the aggR gene (master regulator gene) was conducted to differentiate tEAEC and aEAEC. For 21 virulence genes, we used multiplex PCR to classify possible virulence factors among these strains. Phylogenetic classes were identified by a multiplex PCR for chuA, yjaA, and a cryptic DNA fragment, TspE4C2. Antibiotic susceptibility was conducted by the disc diffusion method as per CLSI guidelines. EAEC was associated with moderate to severe diarrhea in children. The prevalence of EAEC infection (11.4%) was higher than any other DEC group (p = 0.002). tEAEC occurrence in the diarrheal group was higher than in the control group (p = 0.0001). tEAEC strain harbored more virulence genes than aEAEC. astA, aap, and aggR genes were most frequently found in the EAEC from the diarrheal population. Within tEAEC, this gene combination was present in more than 50% of strains. Also, 75.8% of EAEC strains were multidrug-resistant (MDR). Phylogroup D (43.9%) and B1 (39.4%) were most prevalent in the diarrheal and control group, respectively. Genetic analysis revealed EAEC variability; the comparison of tEAEC and aEAEC allowed us to better understand the EAEC virulence repertoire. Further microbiological and epidemiological research is required to examine the pathogenicity of not only typical but also atypical EAEC.

Background. In recent decades, medical community has increasingly been calling attention to the importance of Campylobacter as an disease-causing agent in humans. Nowdays, Campylobacter jejuni (C. jejuni) is known as the most frequent bacterial cause of diarrhea worldwide. Epidemiological differences of the infections caused by Campylobacter, present in the developed and the developing countries, are attributed to the differences of the types of virulence. Due to the specificity, and the demanding features of Campylobacter, as well as poorly equipped microbiological laboratories, campylobacteriosis is insufficiently studied in our country. This investigation aimed to determine the participation of some Campylobacter species in the etiology of diarrheal diseases in our population. Methods. The four-years continuous monitoring of Campylobacter presence was performed in the faeces of 12 605 patients with enterocolitis. The control group included 5 774 examinees of healthy children and youth. Faeces samples were cultivated on Skirrow's selective medium, and further incubated according to effective methodology for Campylobacter. Identification of strains was based on morphological, cultural and physiologic features of strains (oxidase test, catalase test, susceptibility to nalidixic acid, and hypurate hydrolysis). As a statistical method, for data processing, c2 test and Fisher?s exact test were used. Results. Campylobacter was proven in 3.86% of enterocolitis patients, and in 0.71% of healthy population. Out of 518 Campylobacter isolates, 86.48% belonged to enterocolitis outpatients, and 13,51% to inpatients. Predominant symptoms of the disease were diarrhea (81.83%), increased temperature (34.71%), vomiting (19.77%), and stomach pain (15.17%). The diseased were predominantly infants in the first year of life. Out of 300 Campylobacter isolates, 75% were identified as Campylobacer jejuni, 23% as Campylobacter coli (C. coli), and 2% as Campylobacter lari (C. lari). Conclusion. Species of Campylobacter genus participate in the etiology of enterocolitis at 3.86%. According to numerous parameters the infection in our population coincides with the infection in the population of European countries. Frequent findings of C. coli in our region are in discrepancy with the results of numerous studies conducted in the developed countries.

Introduction: Currently, the methods of integrated assessment of patient’s condition based on scoring of separate multidirectional changes in subjective clinical and objective laboratory parameters are used in medical science more and more often. The aim: Based on the identified differences in clinical manifestations and immunological indicators of patients of different age with chronic tonsillitis and patients with no signs of ENT pathology, to develop an integral scoring scale as a basis for an objective assessment of the state of patients with CT and the effectiveness of their treatment. Materials and methods: The clinical signs and immunological factors were evaluated. Patient’s general information, such as age, the presence of allergies, was also taken into account. Based on the analysis of the data array, a scoring system for assessing the clinical and immunological state of patients was proposed. Results: The abnormalities in clinical and immunological assessment in adult population with no signs of ENT pathology (control group) are 2.75 times higher than in healthy children, while in case of chronic tonsillitis the differences between children and adults in terms of integral abnormalities are 1.66 (p<0.05). Conclusions: Integral scoring assessment of clinical and immunological tests makes it possible to provide more objective evaluation of the state of lymphoid tissue of tonsils and the immunity in patients with chronic tonsillitis, which may become an objective basis for choosing patient management strategy, as well as for estimating treatment efficacy.

The aim of the study: to study the efficacy and safety of use Mastofemin in the treatment of various forms of mastitis in women of reproductive age. Materials and methods. The study included 62 women of reproductive age (mean age of 33.5±2.3 years) who were screened in the Kiev city center reproductive and perinatal medicine. Women were divided into 2 groups. The first (main) group consisted of 32 patients who received the proposed treatment using herbal remedies Mastofemin 1 capsule 2 times per day for 3 months; 30 patients of the second (control) group were under observation and received no treatment. These groups were representative and homogeneous on age, clinical symptoms and sonographic characteristics. The clinical method included evaluation of complaints of patients, anamnesis, presence of concomitant gynecologic pathology, inspection, palpation of the lymph nodes and the breast and obtaining a discharge from the nipples to conduct cytological examination, which allowed excluding from the study women with suspected malignancy of the process. All the patients were performed ultrasound examination of the breast. The review was supplemented with vaginal gynecological examination and ultrasound examination of small pelvis organs to assess the condition of the uterus and its appendages, the diagnosis of gynecological diseases. Results. Summarizing obtained in this study results one should stress the positive long-term effect of applying Mastofemin for the treatment of proliferative changes of the breast in women of reproductive age. This is manifested by a decrease in the intensity of clinical signs of mastitis, consistent with the results of sonographic control. Established positive dynamics in the treatment of cystic mastitis, dectective and when combined cystic mastopathy with dectective. In the control group of patients for a given observation period (6 months) no significant changes in clinical signs of mastitis and sonographic characteristics. Regression of disease has not occurred in any of the patients, in 2 patients increased sensitivity of the breast after 6 months moved to the soreness. Sonographic characteristics of mastitis during the observation period did not change. Thus, the use of Mastofemin aimed at pathogenetic treatment of mastitis and prevention of breast cancer. Conclusion. Application of Mastofemin during the treatment of mastitis in women of reproductive age significantly improves the clinical condition of patients; reduce the subjective and objective symptoms of the disease. The positive effect of the treatment with Mastofemin proved in the case of the treatment of sonographic following forms of mastitis: cystic mastopathy, cystic mastopathy with dectectasy. Mastofemin may be the drug of choice for complex conservative monotherapy in women of reproductive age with proliferative changes in the breast, and can also be used as part of complex treatment in patients with diffuse changes of the breast when combined with hyperplastic processes of the myometrium and endometrium. Keywords: mastopathy, breast gland, herbal medicine, herbal remedies, Mastofemin.

THE AIM. To determine the concentration of natriuretic peptide in the blood serum in children with congenital malformations of the urinary system (CM US) and to compare with the activity of renin-angiotensin-aldosterone system (RAAS).MATERIALS AND METHODS.119 patients with CM US aged 3 to 18 years were examined. A control group of 10 clinically healthy children. 3 groups were assigned: group I – 55 children with  congenital vesicoureteral reflux, and group II – 34 children with  congenital hydronephrosis and ureterohydronephrosis, III group – 30 children with other forms of dysembryogenesis of the US. Following indicators were identified by ELISA in the blood: renin, aldosterone,  N – terminal propeptide natriuretic hormone (NT-рroВNР). RESULTS.NT-рroВNР, renin and aldosterone hyperproduction were diagnosed in 59,6%, 69,7%, 54.6 % of sick children relatively. Concentrations were higher in all variants of  malformations in comparison with the control group. Significant  differences were revealed in obstructive species, where arterial  hypertension (AH) was diagnosed more often. Patients with AH  recorded significantly higher concentrations of NT-proВNР and renin.CONCLUSION.The key point in pathological processes developmentand progression in the cardiovascular system and kidneys is the  activation of RAAS. The system of natriuretic factors is important in maintaining the compensated state of patients due to the blockade of RAAS.

Цель исследования. Разработка методов сопроводительной терапии для защиты нормальных органов и тканей, входящих в зону облучения. Методы. В исследование включено 112 больных раком шейки и тела матки после комбинированного или самостоятельного лучевого лечения с 2012 по 2016 гг. У 71 пациентки основной группы в качестве терапии сопровождения применяли гидрогель с деринатом и у 41 больной группы контроля - традиционные методы профилактики (масло оливковое, подсолнечное, метилурациловая мазь). Для профилактики эпителиита слизистой влагалища и шейки матки в основной группе использовали гидрогель в виде аппликаций с первого дня облучения. Для профилактики лучевого ректита гидрогель вводили в прямую кишку 1 раз в день с первого дня облучения. Инстилляции гидрогеля в мочевой пузырь начинали только при развитии первых признаков клинической картины цистита. Пациенткам контрольной группы для профилактики лучевых реакций проводились масляные, мазевые аппликации во влагалище, масляные микроклизмы в прямую кишку с первого дня облучения. Лечение лучевого цистита проводили с помощью растительных диуретиков, уросептиков. Результаты. Применение гидрогеля с деринатом позволило провести курс лучевой терапии без перерыва у 84,5% (60/71) больных, в контрольной группе - лишь у 48,8% (20/41). Лучевые циститы возникали в 2,5 раза реже (25,3% ± 3,3 против 63,4% ± 2,7, р<0,01). Анализ степени выраженности лучевого цистита по RTOG в двух группах показал, что у 75% больных основной группы наблюдалась I степень, у 25% - II степень, III и IV степени не отмечено, тогда как в контрольной группе лучевой цистит I степени развился у 44% пациенток, II - 40% и III - 16% больных. Применение гидрогеля снизило частоту лучевых ректитов в 2 раза (26,7% ± 3,3 против 53,7% ± 3,2 р<0,1).При использовании ежедневных аппликаций гидрогеля с деринатом со стороны слизистой оболочки влагалища и шейки матки преобладали эпителииты I степени (53,5%), II степень наблюдалась у 29,5% и III степень лучевой реакции - лишь в 16,9% случаев, IV степень реакции не отмечена. В контрольной группе эти показатели составили 26,8%, 24,3%, 31,7% и 17,2% соответственно. Разработаны цитологические критерии оценки течения лучевых реакций слизистой влагалища. Выделены три степени изменения цитограммы, которые коррелировали с клинической картиной. В основной группе лучевые изменения I степени зафиксированы в 4,5 раза чаще (52 ± 9,9% против 11,5 ± 6,3%, р<0,002), а III степень представлена в 3,8 раза реже, чем в контрольной группе (12 ± 6,5% против 46,1 ± 9,8%, р<0,003). Заключение. Применение гидрогелевого материала с деринатом в качестве препарата сопроводительной терапии во время курса облучения позволяет уменьшить частоту и степень выраженности лучевых повреждений со стороны слизистой влагалища, мочевого пузыря и прямой кишки, провести курс лучевой терапии без перерыва и улучшить качество жизни пациенток. Objective. Development of methods for accompanying therapy to protect normal organs and tissues in the irradiation zone. Method. The study included 112 patients with cervical and endometrial cancer after combined or independent radiotherapy from 2012 to 2016. In 71 female patients of the main group, Derinat with hydrogel was applied as a supportive therapy and in 41 patients of the control group, conventional prevention methods (olive oil, sunflower oil, methyluracyl ointment) were applied. For prevention of vaginal mucosal and cervical epitheliitis in the main group, hydrogel was used as applications from the first radiation day. For prevention of radiation proctitis, hydrogel was injected into the rectum once daily from the first radiation day. Hydrogel instillations into the bladder were started only with the first clinical signs of cystitis. For prevention of radiation reactions, vaginal oil and ointment and rectal oil micro-enema were administered to patients of the control group from the first day of irradiation. Radiation cystitis was treated with vegetable diuretics and uroseptic drugs. Results. Using the hydrogel with Derinat allowed to administer a course of radiotherapy without interruption in 84.5% (60/71) of patients and only in 48.8% (20/41) in the control group. Radiation cystitis occurred 60% less frequently (25.3% ± 3.3 versus 63.4% ± 2.7, p <0.01). Analysis of radiation cystitis severity in two groups (according to RTOG) showed that 75% of patients in the main group had grade I and 25% had grade II. Grade III and grade IV did not occur. At the same time, in the control group, grade I radiation cystitis developed in 44% of patients, grade II - in 40%, and grade III - in 16% of patients. The hydrogel treatment halved the frequency of radiation proctitis (26.7% ± 3.3 vs. 53.7% ± 3.2 p <0.1). With daily application of the hydrogel with Derinat, grade I epitheliitis (53.5%) predominated in vaginal and cervical mucosa, grade II was observed in 29.5%, and grade III radiation reaction - only in 16.9% of cases; grade IV reaction was not observed. In the control group, these proportions were 26.8%, 24.3%, 31.7%, and 17.2%, respectively. Cytological criteria were developed to evaluate the course of radiation reactions in the vaginal mucosa. Three degrees of change in the cytogram were identified, which correlated with clinical picture. In the main group, incidence of grade I radiation-induced changes was increased by more than 350% (52 ± 9.9% vs. 11.5 ± 6.3%, p <0.002), and incidence of grade III was decreased by more than 70% compared to the control group (12 ± 6.5% vs. 46.1 ± 9.8%, p <0.003). Conclusion. Using the hydrogel material with Derinat as an accompanying therapy during the course of irradiation allows to reduce frequency and severity of radiation injuries of the vaginal mucosa, bladder, and rectum, administer an uninterrupted course of radiotherapy, and improve the quality of life of patients.
