During 2003, we investigated 22 couples with three or more consecutive spontaneous abortions without liveborn children. The study group consisted of 9 couples with three or more successive spontaneous abortions without liveborn children and without known endogenous or exogenous causes of habitual abortions. The first control group comprised 9 couples with liveborn children, while the second one included 9 randomly selected couples without children. The Immunologic status was evaluated in regard to functional capacity of lymphocytes, response of T-lymphocytes to disabled histocompatible antigens of partner's lymphocytes, and T-lymphocytes to partner's alloantigens. In women from study and control groups there were no statistically significant differences in general Immunologic status (functional capacity of lymphocytes). In women from the study group, T-lymphocytes response to stimulation by disabled partner's lymphocytes was significantly lower compared to both control groups (P 0.05). However, the immunologic reaction of women from the study group to alloantigens of men from control groups did not show any significant difference compared to contra/ groups results (P > 0,05). According to our study, it can he concluded that imnntnologic factors have an important role in a great proportion of habitual abortions with unknown etiology.

Background/aims Workers engaged in vehicle spray painting are at a risk of developing respiratory problems because of the solvents in the spray paints. Changes in respiratory functions and functional capacities caused by spray painting can be improved with respiratory exercises. The aim of this study was to examine the effects of respiratory exercises on the respiratory functions, functional capacity and quality of life in vehicle spray painters. Methods A total of 70 volunteers with similar characteristics participated in the study. The groups were divided into two groups randomly (35 study group, 35 control group). Respiratory functions (value of forced expiratory volume percentage in 1 second [FEV1]), forced vital capacity percentage [FVC], FEV1/FVC percentage, peak expiratory flow percentage [PEF (%)] and maximum voluntary ventilation percentage [MVV (%)]), functional capacity (6-Minute Walk Test) and quality of life (Short Form Health Survey [SF-36]) were evaluated. The study group undertook supervised breathing exercises 3 days a week for 6 weeks. The same exercises were given to the control group as a home programme. Home programmes were followed up by telephone calls. Evaluations were performed again after 6 weeks. Results In the study group, FEV1 (%) increased more than in the control group (P<0.05). The increase in PEF (%) was similar in both groups (P>0.05). In the study group, FEV1/FVC (%) and MVV (%) were significantly different before and after the intervention (P<0.05), but there was no difference in the control group (P>0.05). There was a greater increase in the study group than in the control group (P<0.05). 6-Minute Walk Test distance (m) before and after the intervention in both groups were similar (P>0.05). Before and after the intervention, a significant difference was found in the vitality and the social function domains of the SF-36 in the study group. In the comparisons of groups, a significant difference was found in the study group in the role-emotional, social function and bodily pain domains of the SF-36 after the intervention (P<0.05). Conclusions Breathing exercises can be recommended for vehicle spray painters to avoid an increase in respiratory resistance and to improve their quality of life.

Introduction Non-traumatic avascular necrosis of the femoral head (ANFH) is a poly-etiologic and socially significant disease in the age of 20 to 50 years and is associated with disability. Research on the identification of necrosis causes/predictors is a relevant issue. Purpose To study the contribution of polymorphisms in the genes of coagulation factors F7 and F13 in the aetiology of non-traumatic avascular necrosis of the femoral head. Methods Polymorphisms of the genes of coagulation factors F7 and F13 were studied; comparative analysis of the frequency of important allelic variants of F7genes (Arg353Gln) and F13 (Val134Leu) in patients with a verified diagnosis of aseptic necrosis (study group) and in healthy patients (control group) was performed. The study group included 41 patients (all males) with aseptic necrosis of the femoral head of unknown etiology. Results The frequency of gene alleles in the F7 Arg353Gln in the study group were: GG in 30 out of 41 patients (73.2 %), GA in 11 out of 41 patients (26.8 %), and none of 41 patients had a polymorphic variant AA. The frequency of alleles of this type of gene in the control group was as follows: GG in 7 out of 320 subjects (2.2 %), GA in 66 out of 320 patients (20.6 %), AA in 247 out of 320 (77.2 %). Significant differences were identified in the frequencies of homozygous genotypes, AA (χ2 = 100.215, p < 0.001) and GG (χ2 = 205.770, p < 0.001) in the study and control groups respectively. As for the heterozygous GA genotype, the differences were not significant (χ2 = 0.834, p = 0.362). The GG genotype of the gene Val134Leu F13 WAS 2.8 times more frequent in patients of the study group, differences were statistically significant (26.8 % against 9.7 %, χ2 = 10.388; p = 0.002). The presence of the TT genotype of the gene Val134Leu F13 was almost five times more frequent (χ2 = 18.956, p < 0.001) in healthy individuals (control group). Differences in the frequency of allele T in homo/ and heterozygous combinations (TT and GT) in the study and control groups was also significant (72.7 % vs 90.1 %, respectively, χ2 = 4.946, p = 0.027). Discussion Polymorphisms of coagulation factors genes F7 and F13 have a significant effect on the genesis of non-traumatic avascular necrosis of the femoral head. Risk factor of ANFH development is homozygous GG genotype in the gene Arg353Gln F7. Low probability of the disease is due to a protective role of AA genotype of the gene Arg353Gln F7 and TT genotype of the gene Val134Leu F13.

Abstract Background Postpartum hemorrhage (PPH) is the leading cause of maternal mortality. All women who carry a pregnancy beyond 20 weeks’ gestation are at risk for PPH and its sequelae. Although maternal mortality rates have declined greatly in the developed world, PPH remains a leading cause of maternal mortality elsewhere. Aim of the Work To assess the efficacy and safety intravenous tranexamic acid in reduction of amount of blood loss in high risk women who deliver by cesarean section or vaginal delivery in postpartum period. Patients and Methods This prospective double blind randomized controlled clinical trial study was conducted on 200 patients planned for LSCS or vaginal delivery at Gestational Age ≥ 34 Weeks at Ain Shams University Maternity Hospital. Recruitment of data begun once the protocol was approved by research and ethical committee of the department of obstetrics and gynecology. Results No significant difference between Study and Control groups as regards age (p = 0.508), no significant difference between Study and Control groups as regards Gestational age (p = 0.447),total blood loss (p &lt; 0.001) was significantly lower in study group than control group, Vaginal pads in the 1st 24 hours post-partum was significantly less soaked in study group than control group (p &lt; 0.001). no significant difference between Study and Control groups as regards Preoperative Hemoglobin, Postoperative Hemoglobin was significantly higher in study group than control group (p &lt; 0.001), Reduction in Hemoglobin was significantly less in study group than control group (p &lt; 0.001), no significant difference between Study and Control groups as regards Preoperative Hematocrite, Postoperative Hematocrit was significantly higher in study group than control group (p &lt; 0.001), Reduction in Hematocrite was significantly less in study group than control group (p &lt; 0.001).Need to iron replacement or blood transfusion was significantly less frequent in study group than control group (p = 0.24). Conclusion The use of tranexamic acid prior to cesarean section or vaginal delivery is effective as a prophylaxis against post-partum hemorrhage as shown by the results of this study. It can significantly reduce blood loss during and after cesarean section or vaginal delivery.

In this paper, we studied the relation between the micronutrient and gestational diabetes. Therefore, we measured micronutrient concentration including Ni, Al, Cr, Mg, Fe, Zn, Cu, and Se in serum of women with gestational diabetes between 24 and 28 weeks of gestational age (study group) who had inclusion criteria and comparison with micronutrient levels in normal pregnant women with same gestational age (control group). Results showed that there was no significant difference between the serum micronutrient level (Ni, Al, Cr, Mg, Zn, Cu, Se) in study and control groups except serum level of iron which in serum of gestational diabetic women was lower than normal pregnant women and difference was significant.

Purpose: To investigate the levels of circulating CD34+ stem cells in patients with neovascular type age-related macular degeneration (AMD) and its relation with clinical and optical coherence tomography (OCT) findings. Methods: The study consisted of 55 patients: 28 patients (18 male and 10 female) with neovascular type AMD as a study group and 27 patients (12 male and 15 female) scheduled for cataract surgery as a control group. The level of CD34+ stem cells was measured by flow cytometry. Demographic and clinical data were recorded. Results: The mean ages of patients in the study and control groups were 71 ± 8 and 68 ± 6 years, respectively. There was no statistically significant difference in terms of age, sex, or systemic disease association between study and control groups. However, smoking status was significantly higher in the study group (67.9% vs 37.0%; p = 0.02). Stem cell levels were significantly higher in the study group (1.5 ± 0.9 vs 0.5 ± 0.3; p<0.001), but there was no relation between stem cell levels and clinical and OCT findings. Conclusions: Increased circulating CD34+ stem cell levels were observed in patients with choroidal neovascular membrane associated with AMD, but no significant relation was found between cell levels and clinical and OCT findings.

AIM: This study aimed to assess the effectiveness of a recognised antimicrobial resistance (AMR) online module on knowledge and perception among dental students, using a randomised controlled trial study design. METHODS: Dental students (n = 64, aged 21-25 years) in clinical years agreed to participate in this triple-blinded, parallel, randomised controlled trial. There were 34 students in the study group and 30 students in the control group. The study group participated in an online course covering information about AMR, while students in the control group received another online course about microorganisms in dentistry. Both groups were assessed three times using online questionnaires: before the intervention (T1), after the intervention (T2), and two months later (T3). Each one of T1, T2 and T3 had 22 questions. The questions were repeated each time in T1, T2, and T3 asking about AMR but with different question format, to avoid the possibility of students to memorise the answers. RESULTS: The mean (m) of correct answers for all students on T1 was 12.56, with standard deviation (SD) of 3.2. On T2, m = 14.03 and SD = 3.85, and on T3, m = 14.36 and SD = 3.71. Scores ranged from 0 to 22. The participants in the study and control groups showed significant score improvements from T1 to T2, immediately after the intervention, but there was no significant difference between T2 and T3. The study group students’ scores did not improve significantly from T1 to T3, in contrast to the control group students’ scores. More importantly, there was no significant difference in improvement from T1 to T2 when comparing the study and control groups. CONCLUSION: Online courses might not be reliable learning methods for ensuring the optimal levels of AMR knowledge that are needed by dental practitioners.

Abstract Study question The aim of this study is to determine the obstetric outcomes in patients with a singleton birth after hysteroscopic division of septate uterus. Summary answer The data suggest excellent obstetric outcomes for singleton gestation after hysteroscopic division of a septate uterus reaching either the internal or the external cervical os. What is known already Septate uterus is a rare Müllerian anomaly with major impact on reproductive outcomes, particularly with a septum over 10mm. Controversy still exists over the need for surgical correction of the septum due to conflicting data on outcomes, particularly in women with histories of good obstetric outcomes and incidental septum findings. Placental location in relation to the septum may account for such conflicting reports. Most data on reproductive outcomes after hysteroscopic surgical correction combine both septate and subseptate uteri. There is limited published data on obstetric outcomes after hysteroscopic surgical correction of septate uteri, especially septate uteri reaching the external os. Study design, size, duration This retrospective cohort study included 107 patients with infertility and/or recurrent pregnancy loss (RPL) who received treatment between 2002 -2019. The study group included 24 patients with a singleton birth after hysteroscopic correction of septate uterus (Class Va; ASRM classification) that was diagnosed on trans-vaginal 3D ultrasound. The control group included 83 patients with a singleton birth who had normal endometrial cavity on hysteroscopy during the same period of time, before starting treatment. Participants/materials, setting, methods This study was conducted at an infertility clinic affiliated with a teaching hospital. In the study group the septum reached the internal or the external cervical os in 14 and 10 patients respectively. After hysteroscopic correction, all patients were offered various infertility treatments depending on the underlying etiology. The inclusion criterion in this study was to have a singleton birth after hysteroscopy. Demographic and clinical data and obstetric outcomes were compared between the two groups. Main results and the role of chance There was no significant difference in mean age, infertility duration, infertility type and incidence of male infertility or ovulatory disorders between the two groups. There was a significantly higher BMI (0.048), and a higher incidence of history of miscarriage (P=0.002) and history of RPL (P=0.017) in the study group. There was significant lower incidence of tubal factors infertility (P=0.005) and endometriosis (P=0.03) in the study group, therefore there was higher incidence of spontaneous conception (70.8% vs 19.3%; P=0.000) and lower incidence of conception with IVF-ET (20.8% vs 66.3%; P=0.000) in the study group compared to the control group respectively. There was significantly higher incidence of prophylactic cervical cerclage (17.4% vs 0%; P=0.000), and delivery by CS (69.6% vs 41.2%; P=0.019) and lower incidence of vaginal delivery (30.4% vs 58.8%; P=0.019), in the study group compared to the control group. There was no significant difference in gestational age in weeks (38.3 + 1.8 vs 38.6 + 2.0), newborn birth weight in grams (3173.9 + 630.0 vs 3202.1 + 555.6), incidence of premature birth (12.5% vs 12.2%), or other obstetric complications (25% vs 17.6%) between the study and the control groups respectively. For premature births, mean gestational age was 34.3 + 0.47 and 34.6 + 1.2 weeks in the study and control groups respectively. Limitations, reasons for caution A retrospective study has its own inherent bias. Furthermore, the small sample size is explained by the fact that a septate uterus is a rare anomaly leading to difficulties finding cases and organizing a prospective study to achieve a larger sample size. A multicenter prospective study is needed. Wider implications of the findings Regardless of whether the septum reached the internal or external os, there were excellent obstetric outcomes in singleton gestations after hysteroscopic correction of septate uteri. There was no increased risk with septate uteri involving the cervix. Hysteroscopic surgical correction should be the treatment of choice for patients with septate uteri.

This study assesses the upper respiratory tract width at the level of the adenoid in patients with a normal (nasal) and abnormal (oral or mixed) breathing route. <b>Aim</b>. To compare the upper respiratory tract width in the study group (abnormal breathing route) and control group (normal breathing route) and to determine the cut-off point and mean limit values in order to conduct a differential diagnosis between a habitual and constitutional breathing route. <b>Material and methods</b>. The study included 221 patients treated at the Aquadent-Ortoestetyka Clinic in Kielce. Based on the medical history taken, clinical examination and subjective evaluation of the upper respiratory tract width according to Holmberg 112 patients were enrolled into the study group and 109 patients into the control group. The upper respiratory tract width was measured with two different linear methods: a modified method by Holmberg. and Linder-Aronson, and the Linder-Aronson and Henricson method (AD1-PNS, AD2-PNS).<b> Results</b>. In the study group the mean value of the Holmberg measurement is 4.25 mm, and in the control group – 14.1 mm. Mean values of AD1- PNS and AD2-PNS measurements in the study group are 8.1 mm and 9.5 mm, respectively, and they can be regarded as mean limit values. The 6 mm Holmberg measurement is the cut-off value between the study and control groups, and it should be monitored. In relation to the Holmberg measurement a difference between the study and control groups is 9.85 mm. Regarding AD1-PNS and AD2-PNS measurements a difference between the study and control groups is 11.4 mm and 10.0 mm, respectively.<b> Conclusions</b>. The upper respiratory tract width at the level of the adenoid shows a statistically significant difference between the study and control groups. It may indicate significant narrowing of the upper respiratory tract at the level of the adenoid in the study group or a different type of morphology of the facial skeleton. Limit values obtained in the study allow differentiation of a habitual and constitutional breathing route. <b>(Duda A, Stós W.

Abstract Introduction: Child development is the result of the interaction between biological and environmental factors. Objective: The aim of this study is to evaluate and compare the Functional Capacity, Independence and Home Affordances Level of Stimulation of premature children between 18 and 42 months, attending or not daycare centers. Methods: Cross-sectional study with a convenience sample of 26 premature children between 18 and 42 months, paired and divided into two groups: attending (study group) and not attending daycare centers (control group). Data was collected from the questionnaires AHEMD-SR, PEDI and an identification questionnaire. Data analysis was performed by descriptive statistics, and Chi-square, Fisher, Mann-Whitney and Univariate Analysis tests, considering the level of significance of α = 0.05 and tendency of differentiation when α < 010. Results: There was a significant difference in the AHEMD-SR`s Variety of Stimulation (p = 0.036), higher in the control group, and tendency in the Gross Motor Toys (p = 0.086), more available in the study group. In PEDI, there was significant difference in Self-care (p = 0.045) and tendency of differentiation in Mobility (0.068), both of the Caregiver Assistance part (greater to the study). The sample showed low stimulation opportunities regarding Fine and Gross Motor Toys and high percentages of delay in Functional Skills (Mobility) and Independence (Self Care and Mobility), especially in the control group. Conclusion: Daycare centers seem to positively affect the Functional Capacity and Independence in premature children between 18 and 42 months.
