Objective of the research: to present the clinical and laboratory peculiarities of modern whooping cough in hospitalized children of different ages. Materials and methods: сlinical and laboratory characteristics of whooping cough were analyzed in 88 hospitalized sick children aged 1 month to 18 years in groups of children: group 1 – children under 1 year old; group 2 – children 1–6 years old; group 3 – children 7–17 years old. DNA of causative agents of pertussis infection was isolated by PCR in nasopharyngeal swabs using a commercial kit AmpliSens®Bordetella multi-FL (Moscow). Results: children of group 1 in 90% (n=43) of cases were not vaccinated against whooping cough, severe forms were recorded in 17% (n=8) of children of the 1st year of life, and in 15% (n=7) – due to respiratory rhythm disturbances. The diagnosis was confirmed by PCR in 94% (n=45) of children, leukocytosis with lymphocytosis was detected in 81,5% (n=101). Along with hematological changes typical for whooping cough, 79% (n=38) of patients in the first year of life had thrombocytosis (>400×109/l), which was most pronounced in severe disease course 511,5 [425; 568,5]×109/l vs 421 [347; 505,5]×109/l; p<0,05, which has no tendency to decrease throughout the entire observation period and correlates with the level of leukocytes (rs=0,69; p<0,001). Patients over 7 years old in 88% (n=21) of cases were vaccinated against whooping cough, but 79% (n=27) hemograms had no characteristic changes, which, along with a low frequency of confirmation of the diagnosis by PCR 22% (n=4), made it difficult to diagnose whooping cough. Conclusion: children over 7 years of age may not have characteristic hematological changes and PCR diagnostics are insufficiently effective, which contributes to the spread of whooping cough in family foci.

Background Suitable propofol plasma concentrations during gastroscopy have not been determined for suppressing somatic and hemodynamic responses in different age groups. Methods Propofol sedation at target plasma concentrations from 0.5 to 4.0 microgram/ml were performed randomly in three groups of patients (23 per group) who were undergoing elective outpatient gastroscopy: ages 17-49 yr (group 1), 50-69 yr (group 2), and 70-89 yr (group 3). Plasma propofol concentration in which 50% of patients do not respond to these different stimuli were determined by logistic regression: verbal command (Cp50ls), somatic response to gastroscopy (Cp50endo), and gag response to gastroscopy (Cp50gag). Hemodynamic responses were also investigated in the different age groups. Results Cp50ls concentrations were 2.23 microgram/ml (group 1), 1.75 microgram/ml (group 2), and 1.40 microgram/ml (group 3). The Cp50endo values in groups 1 and 2 were 2.87 and 2.34 microgram/ml, respectively, which were significantly higher than their respective Cp50ls values. Cp50endo value in group 3 was 1.64 microgram/ml, which was close to its Cp50ls value. Because of a high degree of interpatient variability, Cp50gag could not be defined. Systolic blood pressure response decreased with increasing propofol concentrations. Conclusions The authors determined the propofol concentration necessary for gastroscopy and showed that increasing age reduces it. Propofol concentration that suppresses somatic response induces loss of consciousness in almost all young patients.

Introduction: hypertension and diabetes remain the main risk factors for stroke, which leads to premature disability and mortality. The aim: To study the dynamics of blood pressure (BP) in patients of different age groups with hypertension and diabetes type II before and after carotid endarterectomy. Materials and methods: 90 patients with hypertension and diabetes type II were selected for CE. Patients are divided into two age groups: up to 65 years (group 1) and after 65 years (group 2). We assessed the dynamics of ambulatory blood pressure monitoring (ABPM). The examination was carried out 2 days before and 6 months after surgery. CE was conducted under local anaesthesia. Results: Before operation in patients in group 2, there was a significantly higher level of average systolic BP per 24 hours (p <0.02), per day (p <0.01), per night (p <0.01) and diastolic BP per night (p <0,01). At the preoperative stage, there was a significant increase in the parameters of the variability of BP, but the increase in the variability of BP with age was not fixed. After surgery, patients with Group 1 observed a more significant positive dynamics of ABPM indices than patients in Group 2. In two age groups, the percentage of patients with an insufficient reduction of BP at night was prevalent. Conclusions: Surgical treatment of carotid stenosis is associated with a steady decrease in BP in the distant period after CE. Significant regression of BP is characteristic for patients of the younger age group.

Understanding age-specific injury patterns allows the continued improvement of prevention strategies. This is a retrospective study analyzing the Korea Emergency Department-Based Injury In-depth Surveillance data, including those aged ≤19 years old between January 2011 and December 2017. In this study, we focused on changes in the modes of injury and severity, and prevention potential by dividing the patients into four age groups: group 1 (0–4 years), group 2 (5–9 years), group 3 (10–14 years), and group 4 (15–19 years). The most common mode of injury in younger age groups 1 and 2 was a fall or slip. Most injuries in older age groups 3 and 4 were unintentional and intentional collisions combined. Traumatic brain injuries (2.1%), intensive care unit admissions (1.8%), and overall death (0.4%) were the highest in group 4. The proportions of severe and critical injury (EMR-ISS ≥ 25) were 7.5% in group 4, 3.2% in group 3, 2.5% in group 1, and 1% in group 2. This study presents a comprehensive trend of injuries in the pediatric population in South Korea. Our results suggest the importance of designing specific injury-prevention strategies for targeted groups, circumstances, and situations.

Background: Pitching velocity is one of the most important metrics used to evaluate a baseball pitcher’s effectiveness. The relationship between age and pitching velocity after a lighter ball baseball training program has not been determined. Purpose/Hypothesis: The purpose of this study was to examine the relationship between age and pitching velocity after a lighter ball baseball training program. We hypothesized that pitching velocity would significantly increase in all adolescent age groups after a lighter baseball training program, without a significant difference in magnitude of increase based on age. Study Design: Cohort study; Level of evidence, 2. Methods: Baseball pitchers aged 10 to 17 years who completed a 15-week training program focused on pitching mechanics and velocity improvement were included in this study. Pitchers were split into 3 groups based on age (group 1, 10-12 years; group 2, 13-14 years; group 3, 15-17 years), and each group trained independently. Pitch velocity was assessed at 4 time points (sessions 3, 10, 17, and 25). Mean, maximum, and mean change in pitch velocity between sessions were compared by age group. Results: A total of 32 male baseball pitchers were included in the analysis. Mean/maximum velocity increased in all 3 age groups: 3.4/4.8 mph in group 1, 5.3/5.5 mph in group 2, and 5.3/5.2 mph in group 3. While mean percentage change in pitch velocity increased in all 3 age groups (group 1, 6.5%; group 2, 8.3%; group 3, 7.6%), the magnitude of change was not significantly different among age groups. Program session number had a significant effect on mean and maximum velocity, with higher mean and maximum velocity seen at later sessions in the training program ( P = .018). There was no interaction between age and program session within either mean or maximum velocity ( P = .316 and .572, respectively). Conclusion: Age had no significant effect on the magnitude of increase in maximum or mean baseball pitch velocity during a velocity and mechanics training program in adolescent males.

This study aims to analyse and quantify the possible retinal microvascular abnormalities.Materials and methodsCase–control study. Patients between 18 and 55 years old with PCR-confirmed SARS-CoV-2 infection within the last 3 months were included. Risk stratification: group 1—mild disease (asymptomatic/paucisymptomatic); group 2—moderate disease (required hospital admission with no acute respiratory distress) and group 3—severe disease (subjects who developed an acute respiratory distress were admitted in the intensive care unit and presented interleukin 6 values above 40 pg/mL). Age-matched volunteers with negative serology tests were enrolled to control group. A colour photograph, an optical coherence tomography (OCT) and an angiography using OCT centred on the fovea were performed.ResultsControl group included 27 subjects: group 1 included 24 patients, group 2 consisted of 24 patients and 21 participants were recruited for group 3. There were no funduscopic lesions, neither in the colour images nor in the structural OCT. Fovea-centred vascular density (VD) was reduced in group 2 and group 3 compared with group 1 and control group (control group vs group 2; 16.92 vs 13.37; p=0.009) (control group vs group 3; 16.92 vs .13.63; p=0.026) (group 1 vs group 2; 17.16 vs 13.37; p=0.006) (group 1 vs group 3; 17.16 vs 13.63 p=0.017).ConclusionPatients with moderate and severe SARS-CoV-2 pneumonia had decreased central retinal VD as compared with that of asymptomatic/paucisymptomatic cases or control subjects.

ABSTRACT In this study we investigated whether the enterohemorrhagicEscherichia coli (EHEC) hemolysin gene ehxAcould be used as an indicator of pathogenicity in Shiga-like-toxin-producing Escherichia coli (SLTEC) isolates. The isolates in a collection of 770 SLTEC strains of human and bovine origins were assigned to group 1 (230 human and 138 bovine SLTEC isolates belonging to serotypes frequently implicated in human disease), group 2 (85 human and 183 bovine isolates belonging to serotypes less frequently implicated in disease), and group 3 (134 bovine isolates belonging to serotypes not implicated in disease). PCR amplification was used to examine all of the SLTEC isolates for the presence of ehxA and the virulence-associated geneseae, slt-I, and slt-II. The percentages of human isolates in groups 1 and 2 that were positive forehxA were 89 and 46%, respectively, and the percentages of bovine isolates in groups 1 to 3 that were positive forehxA were 89, 51, and 52%, respectively. The percentages of human isolates in groups 1 and 2 that were positive foreae were 92 and 27%, respectively, and the percentages of bovine isolates in groups 1 to 3 that were positive for eaewere 78, 15, and 19%, respectively. The frequencies of bothehxA and eae were significantly higher for group 1 isolates than for group 2 isolates. The presence of the ehxA gene was associated with serotype, as was the presence of the eae gene. Some serotypes, such as O117:H4, lacked both eae and ehxA and have been associated with severe disease, but only infrequently. Theslt-I genes were more frequent in group 1 isolates than in group 2 isolates, and the slt-II genes were more frequent in group 2 isolates than in group 1 isolates. In a second experiment we determined the occurrence of the ehxA andslt genes in E. coli isolated from bovine feces. Fecal samples from 175 animals were streaked onto washed sheep erythrocyte agar plates. Eight E. coli-like colonies representing all of the morphological types were transferred to MacConkey agar. A total of 1,080 E. coli isolates were examined, and the ehxA gene was detected in 12 independent strains, only 3 of which were positive for slt. We concluded that the ehxA gene was less correlated with virulence than the eae gene was and that EHEC hemolysin alone has limited value for screening bovine feces for pathogenic SLTEC because of presence of the ehxA gene in bovine isolates that are not SLTEC.

ABSTRACT Objective: This study was designed to investigate radiographically the effects of age and external irritating stimuli on the morphology and thickness of the pulp chamber ceiling and floor in mandibular molars. Materials and Methods: A total of 234 panoramic radiographs were recruited and 494 mandibular molars were examined in this study. The sample was divided into six age groups: Group 1, <20 years; Group 2, 20-29 years; Group 3, 30-39 years; Group 4, 40-49 years; Group 5, 50-59 years and Group 6, >60 years. Each group was subdivided into two subgroups with regard to the tooth condition (intact or non-intact teeth). Four distances, two angles and two ratios were measured, in order to estimate the dimensions of the pulp chamber and the thickness of the pulp chamber ceiling and floor. Results: The thickness of the pulp chamber ceiling and floor increased significantly from Group 1 to 6. The pulp chamber floor angle presented progressive sharpness from Group 1 to 6 whereas the pulp chamber ceiling angle presented progressive bluntness from Group 1 to 5 and sharpness from Group 5 to 6. Significant differences were identified in the thickness of the pulp chamber ceiling, the thickness of the pulp chamber floor and the ceiling-floor distance between intact and non-intact teeth. Conclusion: Based on those results, there are differences in the location of secondary dentin formation between the two pulp chamber walls. Age is related to diminished pulp chamber size. The increase rate of the pulp chamber ceiling thickness is similar to that of the pulp chamber floor thickness. Furthermore, external irritating stimuli have an effect on the pulp chamber dimensional changes.

Background Pediatric regional anesthesia has gained increasing interest over the past decades. The current study was conducted to investigate the lumbar paravertebral region and the lumbar plexus at L3-L4 and L4-L5 by means of sonography to obtain fundamentals for the performance of ultrasound-guided posterior lumbar plexus blocks. Methods Thirty-two children (12 boys, 20 girls) with American Society of Anesthesiologists physical status I or II were enrolled in the current study. The lumbar paravertebral region was visualized at L3-L4 and L4-L5 on two corresponding posterior sonograms (longitudinal, transverse). The lumbar plexus had to be delineated, and skin-plexus distances were measured. In a series of five pediatric patients undergoing inguinal herniotomy, ultrasound-guided posterior lumbar plexus blocks at L4-L5 were performed. Results The children were stratified into three age groups (group 1: &gt; 3 yr and &lt;/= 5 yr; group 2: &gt; 5 yr and &lt;/= 8 yr; group 3: &gt; 8 yr and &lt;/= 12 yr). The lumbar plexus could be delineated at L3-L4 and L4-L5 in 19 of 20 cases in group 1, in 17 of 20 cases in group 2, in 22 of 24 cases at L3-L4 in group 3, and in 16 of 24 cases at L4-L5 in group 3. In all patients, the lumbar plexus was situated within the posterior part of the psoas major muscle. Skin-plexus distances showed statistical significant differences between groups 1 and 3 and between groups 2 and 3. The strongest positive correlation existed between skin-plexus distances and the children's weight. Ultrasound guidance enabled safe und successful posterior approaches to the lumbar plexus, thus resulting in effective anesthesia and analgesia of the inguinal region. Conclusions Sonography of the lumbar plexus in children proved to be feasible. Skin-plexus distances correlated with the children's weight rather than with their age. The sonographic findings were fundamental for the performance of successful ultrasound-guided posterior approaches in a small group of pediatric patients.

SUMMARYA study was made of the R factors from two multiply drug resistant wild type isolates ofPseudomonas aeruginosafrom a Birmingham hospital (Lowburyet al.1969) from which, in contrast to other strains from the same source (Chandler & Krishnapillai, 1974a), drug resistance was not transferable toEscherichia coliK12 orSalmonella typhimurium. Transfer of drug resistance occurred at a low frequency toShigella flexneri, although drug resistance in this species was subsequently non-transferable.InP. aeruginosathere are several features of these two R factors which distinguish them from the group 1 and 2 R factors described previously (Chandler & Krishnapillai, 1974a). Although coding for resistance to neomycin and tetracycline, they did not express this resistance in two strains ofP. aeruginosaexamined, in contrast to the wild type strains they were isolated in.The control of transfer of the two R factors is different to the group 1 and 2 R factors in that derepression of transfer could be demonstrated following physiological treatments or mutagenesis. The R factors of this third group were compatible with the group 2 R factors, but did not repress their pilus synthesis on the basis of R factor specific phage plating.

Preterm labor is one of the most current problems of modern medicine. Preterm labor is defined as the birth of a child in the gestation period less than 37 full weeks of gestation and is the second most common cause (after congenital anomalies) of neonatal mortality [3]. The highest percentage of morbidity and mortality occurs in children born to gestational age less than 32 weeks, although the proportion of these newborns is 16 % of all preterm infants [4]. Preterm labor is a polyetiology problem that depends on many factors. One of the major problems is the formation of placental dysfunction, which manifests itself by morphofunctional changes in the placenta associated with violation of uterine-placental circulation. The aim of the study – to obtain the peculiarities of placentas’ histological condition in women with burdent anamnesis and preterm labor with different Apgar point scale of newborn. Materials and Methods. A total of 19 placentas of women with preterm labor were observed in Maternal Hospital No. 5 of Odesa, Ukraine. We studed their residence areas, obstetrical and gynacology anamnesis, current pregnancy and labor anamnesis. We exa­mined the ultrasound datas of the newborns, studied their anthropometric, Apgar scale and histology of placentas’ datas. All interviewed women were devided into two groups: less than 35 years old – 12 women of the group 1 and more than 35 years old – 7 women, it was the group 2. The average age of the examined groups was 31.3 years old. Statistical datas processing was carried out by using the Fisher angular transformation. The degree of probability (P) between two comparative values was considered to be statistically valid when P<0.05. The research results showed that all elder women were married, lived in ecoregions of the city, had more often revolved to artificial reproductive technologies, had singleton gestation compared to younger group of patients. Newborns of women afer 35 had better points of Apgar scale and no one had IUGR compared to newborns of the younger women. Signs of placenta dysfynction were detected in placentas of both groups of women. Conclusions. In our investigation the women of different age groups with preterm labor had signs of placenta dysfunction but women after 35 years had better datas of newborn babies according to Apgar scale and absence of IUGR. Probably, it is connected with residency, official marriage and better preconceptional preparation in this group.
