Background: Osteosarcoma is a malignant bone disease. Predictors which used to determine osteosarcoma from non-invasive (stage IIB) to invasive (stage III), through the ratio of macrophages-1 (M-1) which are pro-inflammatory (anti-cancer) with macrophages-2 (M-2) which have anti-inflammatory characteristic (pro cancer) is not clear yet.Purpose: To elaborate the role of M-1 ratio with M-2 in the development of non-invasive osteosarcoma become invasive, in effort to obtain predictors that can be used to the selection of neoadjuvant therapy time.Methods: An observational study with cross sectional analytic study design. The sample of this research were all of paraffin blocks containing osteosarcoma patient tissue, collected within 5 years. The number of samples that met the inclusion criteria was 26 samples, and then divided into two groups, namely group-I as many as 13 stages IIB and group-II as many as 13 samples of stage III. The measured variables are the number of macrophages that express TNF-α and those that express IL-10 by immunohistochemical methods.Results: Analysis of the data using a Mann-Whitney test, and the results were obtain is the number of macrophages expressing TNF-α in group-I was greater than in group-II (p <0.05). Likewise, macrophages that expressed IL-10 in group I were smaller than in group-II (p <0.05).Conclusion: The M-1 ratio which reflected by TNF-α expression cells with M-2 as reflected by IL-10 expression cells in the non-invasive group is 5: 1.Whereas in the group that develops to invasive is 1:6.

Study Objective: To evaluate the effect of low molecular heparin (LMH) therapy on non-invasive prenatal DNA screening (NIPS) for chromosomal pathologies. Study Design: cross-sectional study. Materials and Methods. We have examined two groups of pregnant women: group I included 49 patients with constantly low foetal DNA (twice lower than 4%) selected out of 1,505 women examined at Kulakov National Medical Scientific Centre of Obstetrics, Gynaecology and Perinatal Medicine of the Ministry of Health of Russia during the last 2 years. 17 women were administered LMH and 32 women did not receive it. Group II included 113 pregnant women with a normal foetal DNA fraction (at least 4%), that were selected randomly out of patients who were examined during the same period. 56 pregnant women were administered LMH and 57 were not. Next Generation Sequencing was used as an NIPS method. In order to determine the foetal DNA level, we amplified DNA loci with single nucleotide polymorphisms. Study Results. In group I (low foetal DNA fraction), where no LMH therapy was initiated, median values were 3.5% (3.2–3.8%); if LMH was administered, these values made 3.6% (3.4–3.9), while in group II — 7.7% (6.1–9.5%) and 7.9% (6.0–10.5%), respectively; no significant differences (p = 0.29 and p = 0.7, respectively) were recorded in both cases. Conclusion. Use of LMH does not affect NIPS; therefore, it is not necessary to adjust the LMH therapy in pregnant women prior to NIPS. Keywords: non-invasive prenatal DNA screening, heparin, anticoagulants, low molecular heparins, habitual abortion, pregnancy complications.

Summary Initial combination drug regimen containing cisplatin in patients with stage III and IV head and neck cancer produced a high percentage of clinical response. This trial was initiated to assess the role of multimodality treatment (chemotherapy plus radiotherapy) versus chemotherapy alone. Ninety-six patients entered into this study; 80 patients were evaluable at time of analysis (Table I). Patients were randomized between chemotherapy and radiotherapy (group I) and chemotherapy alone (group II). The chemotherapy administered consisted of cisplatin, bleomycin and methotrexate and was given in 2 cycles over 35 days. Local radiotherapy followed. In group II 3 cycles of chemotherapy were given without radiotherapy. The overall tumour response after chemotherapy rose up to 75 per cent. After radiotherapy in group II the response rate sank to 59 per cent. In both regimes the remission duration was very short. Patients receiving only two cycles of chemotherapy do not have a statistically shorter survival than patients, who were treated by chemotherapy plus radiotherapy, or by a 3rd cycle of chemotherapy.

Hepatocellular Death

The aim of the study was to assess the role of hepatocellular death and systemic inflammation in the development of acute kidney injury (AKI) in acute decompensation of alcoholic liver cirrhosis (AD ALC).Materials and methods. 125 patients with ALC were examined: 20 (16.0%) (group I) with signs of hepatorenal syndromeacute kidney injury (HRS-AKI) at the age of 57.13 ± 9,08 years, 13 men (65.0%) and 105 (84.0%) patients (group II) without such a syndrome at the age of 56.30 ± 9.6 years., 62 men (59.0%). Along with liver tests, a markers of hepatocyte apoptosis and cytokines were determined by ELISA: fragments of cytokeratin-18 (FCK-18) ("Biotech" Sweden), cytokines — TNF-α, IL-1β, IL-4, IL-6, IL-8 (“Vector-Best”, Russia). Grade and index of acute on chronic liver failure (ACLF) were determined using an on-line calculator (www.efclif.com/scientific-activity/score-calculators/clif-c-aclf).Results. The hepatocellular death indicators were significantly higher in patients of group I with HRS-AKI compared with patients of group II without HRS-AKI: FCK-18-1609.44 ± 542.79 U / l versus 975.77±607.59 U / l, bilirubin — 242.64 ± 98.14 pmol/l versus 145.09 ± 79.35 pmol/l, inflammation indicators — TNF-α — 9.28 ± 3,11 pg/ml versus 6.59 ± 2.21 pg/ml, IL-6-54.79 ± 17.7 pg/ml versus 36.71 ± 18.05 pg/ml, CRP — 49.68 ± 23.23 mg/l versus 22.07 ± 20.40 mg/l, leukocytes — 12.23 ± 3.28x109/l versus 8,66 ± 2,31x109/l (everywhere p <0.05). ACLF developed in all (100.0%) patients of group I, its grade was 2.73±0.76 and score — 56.33 ± 4.01; ACLF developed only in 37 (35,2%) patients of group II, its grade was1.05±0.24 (p<0,05) and score was 47.45 ± 4,80 (p <0.05).Conclusion. The development of HRS-AKI in patients with acute decompensation of ALC was associated with significantly higher rates of hepatocytic apoptosis, hyperbilirubinemia, systemic inflammation, frequency and severity of ACLF.

In this study, genotoxic effects of repeated sevoflurane anaesthesia were investigated in rabbits with or without antioxidant supplementation. Twenty-one New Zealand male rabbits were included in the study and randomized into three groups as: placebo treated (Group I), vitamin E supplemented (Group II) and selenium supplemented (Group III). Vitamin E and selenium were given intraperitoneally for 15 days before anaesthesia treatment. Anaesthesia was administered using 3% sevoflurane in 4 L/min oxygen for a 3-hour period and continued for 3 days. Blood samples were collected before anaesthesia (Sample 1), after the first, second and third days of sevoflurane administration (Sample 2, Sample 3 and Sample 4 respectively) and the last samples were taken 5 days after the last sevoflurane administration (Sample 5). Genotoxic damage was examined using the comet assay. The degree of damage is assessed by grading the cells into three categories of no migration (NM), low migration (LM) and high migration (HM) depending on the fraction of DNA pulled out into the tail under the influence of the electric field. The number of comets in each sample was calculated (1 × number of comets in category NM + 2 × number of comets in category LM + 3 ×number of comets in category HM) and expressed as the total comet score (TCS), which summarizes the damage frequencies. In Group I, a significant increase in the mean TCSs was observed for Samples 3 and 4 as compared with Sample 1. However, there were no significant differences between Samples 1, 2 and 5. The mean TCS of Sample 4 was significantly higher than Sample 1, 2 and 3 in Group II. Group III demonstrated no significant mean TCSs for any experimental conditions. Statistical differences were also observed between the groups with significant P values. This experimental study points out the presence of DNA damage with repeated sevoflurane anaesthesia and the genoprotective role of antioxidant supplementation on DNA damage in mononuclear leukocytes of rabbits by highly sensitive comet assay.

Objective. The aim of the current study was to laparoscopically investigate the effects of peritoneal nonclosure on the sites, types, and degrees of adhesions developed after primary caesarean section (CS) in women complaining of secondary infertility after first CS delivery. Study Design. This was a cross-sectional study, where 250 women suffering from secondary infertility after their first CS had been recruited. They had been classified into group I (n = 89), where both the visceral and parietal peritoneum had been left opened; group II (n = 75), where only the parietal peritoneum had been closed; and group III (n = 86), where both peritoneal layers had been closed. Laparoscopy had been used to classify those adhesions according to the location, severity, and their adverse impact on the reproductive capacity. Results. Both adnexal and nonadnexal adhesions had been found significantly higher in group I, while adnexal types of adhesions were significantly higher after nonclosure of the visceral peritoneum in group II. Laparoscopic tubal surgery performed included tubo-ovariolysis, fimbrioplasty, and neosalpingostomy. Pregnancy rate was found correlating with the adnexal adhesion location and score. Conclusion. Nonclosure of the peritoneum in CS is associated with more adhesion formation, which might adversely affect the future women reproduction.

Objective. To determine the current practice and effectiveness of evaluating recurrent syncope in pediatric patients, and to establish the role of tilt table testing in the evaluation. Design. Retrospective analysis of 54 pediatric patients with the history of syncope referred to cardiologists. Group I consisted of 27 patients examined without tilt table testing group II consisted of 27 patients whose examination included tilt table testing. Results. Group I had an average of 5.4 studies and group II, 6.6 studies performed per patient. Studies included chest radiograph (16 vs 13), electrocardiogram (24 vs 27), echocardiography (21 vs 27), 24-hour electrocardiogram (14 vs 16), transtelephonic monitor (7 vs 8), electrophysiology study (1 vs 3), complete blood cell counts (11 vs 12), chemistries (10 vs 11), thyroid function test (3 vs 3), neurology consult (12 vs 6), electroencephalogram (12 vs 5), and head computed tomographic scan (5 vs 3). Of the 298 non-tilt studies, the results of only 5 (1.6%) were abnormal. Diagnoses were made in 5 (18.5%) of 27 group I patients (Wolff-Parkinson-White syndrome, 1; conversion reaction, 2; hyperventilation, 1; migraines, 1), whereas diagnosis was made in 27 (100%) of 27 group II patients (neurocardiogenic syncope, 25; conversion reaction, 2). Conclusion. An extensive workup is not routinely indicated in syncopal patients with a history consistent with neurocardiogenic syncope. Tilt table testing performed early in the evaluation will increase the probability of a diagnosis, and will often prevent the need for further extensive, expensive anxiety-producing tests.

Objective. To analyze clinical and laboratory parameters, as well as the dynamics of cytokine production in children of different ages with acute infectious mononucleosis caused by Epstein-Barr virus (EBV mononucleosis). Patients and methods. We examined two groups of patients: group I included 20 children aged 1 to 7 years, whereas group II included 29 children aged 8 to 17 years. All study participants were tested in the acute phase of the disease and in early convalescence. We evaluated serum levels of interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α (TNF-α), and interferon-α (IFN-α) using enzyme-linked immunosorbent assay (ELISA) (standard Vektor-Best kits, Russia). Data analysis was performed using Microsoft Excel 2019 for Windows and IBM SPSS statistics; we applied the methods of non-parametric statistics. Differences were considered significant at p < 0.05. Results. The majority of children had fever, intoxication, acute tonsillitis, and enlarged cervical lymph nodes. Laboratory makers, such as lymphocytosis, neutropenia, and thrombocytopenia were more pronounced in children from group II. In both groups, the level of cytokines in the acute period of the disease was higher than the discriminatory one. In early convalescence, patients from group I demonstrated more significant reduction in the cytokine level than patients from group II (р < 0.05). In children over 7 years of age, the levels of IL-10 and TNF-α positively correlated with the disease duration (p < 0.01 and p < 0.05, respectively) Conclusion. The level of cytokine production in acute EBV mononucleosis depends on patients’ age. Concentrations of IL-10 and TNF-α can serve as markers reflecting the severity of EBV mononucleosis and can be used for disease prognosis. Key words: EBV mononucleosis, children, cytokines, IL-6, IL-10, TNF-α, IFN-α

Abstract Introduction Nowadays interest in aging has greatly increased, Aging is a complex natural process involving every molecule, cell, and organ in the body that is associated with tissue dysfunction in many organs. Aging of the cornea causes major eye effects and leads to substantial cost in medical and social terms. These effects include the highly prevalent dry eye disease (DED) that affects both visual function and quality of life in elderly. Symptoms of (DED) include, ocular pain, visual disturbances, and increase lacrimation. Functional foods such as Royal jelly (RJ) have a growing attention because of consumers increasing concerns about their health. Its importance not only for its nutritional properties but also for its functional and biological properties such as antioxidant, anti-inflammatory, antibacterial, antiviral, and anti-ulcerous activities. It is used as a cheap natural source in daily life and medicine. (RJ) is a complex substance composed of proteins, sugars, lipids, amino acids, vitamins, and minerals. Aim The present study aimed to investigate the histological effect of aging on the cornea of male albino rat and possible therapeutic role of (RJ) on senile group. Materials and Methods Twenty-four male albino rats were used in this study divided into Group I: consisted of 6 adult male rats aged 3- 6 months. Group II: consisted of 18 senile male rats aged 18-24 months, were further subdivided into three subgroups as follows: Group II A: (n = 6) negative control senile rats, not subjected to any procedure for 4 weeks. Group II B: (n = 6) control senile rats and were given distilled water by oral gavage once daily for 4 weeks. Group II C: (n = 6) senile rats were given (RJ) by oral gavage dissolved in distilled water once daily for 4 weeks. At the end of the experiment, rats were sacrificed after being deeply anesthetized with ether according to the protocol of the Committee of Animal Research Ethics (CARE). The cornea of each animal was carefully dissected out after death and immediately fixed in 10% formalin for preparation of paraffin blocks 5 micrometer thickness. Sections were stained with hematoxylin and eosin (I-I&E), Masson's trichrome and periodic acid-Schiff (PAS). Statistical analysis and quantitative morphometric study were done. Results Light microscopic examination of corneas of senile rats revealed different pathological changes included irregularity in the surface epithelium as well as surface erosions and cytoplasmic vacuolations. The stroma showed widely separated collagen fibers with decreased keratocyte density. It was concluded that (RJ) supplementation to senile rats obviously unproved all layers of the cornea histologically.

Background: Adequate neonatal transport is a key component of care of the sick newborns who require referral to tertiary care center. Poor transportation is one of the iatrogenic factors associated with greater neonatal mortality. Neonatal transport is the greatest challenge faced today in our country. The purpose of this study was to find out characteristics of transport of referred neonates and to idention the factors that contribute to mortality.Methodology: This cross sectional study was conducted in Dhaka Shishu (Children) Hospital from June 2013 to November 2013. Both term and preterm neonates who were referred within first seven days of life were included and those with gross congenital abnormalities and left against medical advice were excluded from the study. After enrollment, data were collected using a structured questionnaire including birth details, interventions before transportation, reasons for referral, and details of transportation. Outcome & duration of hospital stay were also recorded. Neonates who were expired considered as group I and who were survived considered as group II. The study variables were analyzed for their association with immediate outcome by applying chi square test and t test. P value <0.05 was considered significant.Results: This study found that out of 332 neonates 181 were expired with 54.5% mortality rate. One eighty one neonates who were expired, considered as group I and one fifty one neonate were survived, considered as group II. The mortality was significantly high in male neonates [RR 0.80 (0.66-0.97)] and neonates those delivered at home [RR 1.34(1.10-1.64)] (p<0.05). Perinatal asphyxia, pre-term low birth weight, neonatal sepsis were the main causes of referral. It was found that transportation without any referral note [RR 1.40 (1.14- 1.71)], no advice regarding maintenance of airway[RR 1.50(1.17- 1.92)]and keeping warm [RR 1.51(1.17-1.950], resuscitation on admission [RR 1.63(1.23-2.17)] and transportation required > 3hours [RR 1.36(1.09-1.69)] were associated with significantly higher mortality among referred transported neonates(p<0.05).Conclusions: This study found that male neonates, home delivery, transportation without any referral note, no advice regarding maintenance of airway and keeping warm, resuscitation needed on admission and prolonged transportation time were significantly associated with mortality of referred transported neonates.Bangladesh J Child Health 2017; VOL 41 (3) :159-164

We have determined the sites of action of endothelin-1 (ET) in the lamb pulmonary circulation. The influence of cyclooxygenase inhibition and baseline vasomotor tone on ET effects was also studied. Lungs of 14 lambs (6-9 wk of age, 12.1 +/- 0.6 kg body wt) were isolated and perfused with blood. Group I lungs (n = 5) were untreated, group II lungs (n = 5) were treated with indomethacin to inhibit cyclooxygenase, and group III lungs (n = 4) were treated with indomethacin and a thromboxane A2 analogue, U-46619, to elevate vasomotor tone. All lungs were perfused with constant flow in zone 3, with left atrial and airway pressures being 8 and 6 cmH2O, respectively. We measured pulmonary arterial pressure and, by the micropuncture servo-null method, pressures in 20- to 50-microns diameter subpleural venules, both before and after each dose of ET was infused (50, 100, 250, and 500 ng/kg). Group I lungs, with high baseline vasomotor tone, exhibited a biphasic response to ET; 50-100 ng/kg of ET dilated both arteries and veins, whereas 500 ng/kg of ET constricted both arteries and veins. In group II lungs with low vasomotor tone, all doses of ET caused constriction of arteries only. In group III lungs (indomethacin treated with elevated vasomotor tone), 50-100 ng/kg of ET caused dilation of arteries and veins, whereas 500 ng/kg of ET induced constriction, this time only in arteries. We conclude that ET has both dilator and constrictor effects in arteries and veins of isolated, perfused lamb lungs. ET-induced arterial and venous dilation is dependent on initial vasomotor tone but not on cyclooxygenase metabolites.(ABSTRACT TRUNCATED AT 250 WORDS)
