Relationship between seasons and pregnancy rates during intrauterine insemination. A historical cohort

ABSTRACT BACKGROUND: The underlying cause of seasonal infertility in humans is unclear, but is likely to be ­multifactorial. OBJECTIVE: The aim of our study was to compare the pregnancy rates among infertile women who underwent induced ovulation and intrauterine insemination (IUI) with the season in which the fertility treatment was performed. DESIGN AND SETTING: This retrospective cohort study was conducted on 466 patients who were treated in the reproductive endocrinology and infertility outpatient clinic of a tertiary-level women's healthcare and maternity hospital. METHODS: Retrospective demographic, hormonal and ultrasonographic data were obtained from the patients' medical records. Clomiphene citrate or gonadotropin medications were used for induced ovulation. The patients were divided into four groups according to the season (spring, winter, autumn and summer) in which fertility treatment was received. Clinical pregnancy rates were calculated and compared between these four groups. RESULTS: There were no significant differences between the seasonal groups in terms of age, infertility type, ovarian reserve tests, duration of infertility, medications used or length of stimulation. A total of 337 patients (72.3%) were treated with clomiphene citrate and 129 (27.7%) with gonadotropin; no significant difference between these two groups was observed. The clinical pregnancy rates for the spring, winter, autumn and summer groups were 15.6% (n = 24), 8.6% (n = 9), 11.5% (n = 13) and 7.4% (n = 7), respectively (P = 0.174). CONCLUSIONS: Although the spring group had the highest pregnancy rate, the rates of successful IUI did not differ significantly between the seasonal groups.

Evaluation of FMR1 gene mutations in Turkish women newly diagnosed with primary ovarian failure

Background: One of the known causes of ovarian dysfunction is fragile X mental retardation gene 1 (FMR1) premutation. The prevalence of FMR1 premutation in primary ovarian failure (POF) cases may differ between the studies due to some reasons including POF definition, definition of premutation, and determination of study population, ethnicity, genetic and environmental factors. In this study authors aimed to determine the prevalence of FMR1 mutations in patients who applied to present clinic and diagnosed as POF.Methods: This retrospective cohort study was conducted on 200 women who had been newly diagnosed with POF in present clinic between 2013 and 2014. The presence of cytogenetic fragility was firstly investigated in all patients by using the lymphocyte culture method, and molecular analysis of the FMR1 gene was then performed. Genomic DNA’s of cases were isolated using standard protocols, followed by polymerase chain reaction amplification with an appropriate program. Fragment analysis of the amplification products were performed by agarose gel electrophoresis.Results: Cytogenetic analysis results in 200 cases were numerically and structurally normal in all patients, and as a result of molecular genetic analysis of FMR1 gene; 1 (0.5%) patient had complete mutation and 9 (4.5%) patients had premutation carriage.Conclusions: FMR1 gene mutations are common in women with POF. These mutations should be investigated in all patients presenting with POF, particularly in cases with early onset and family history of POF, and also genetic counseling should be given to those patients.

Protective effect of omega 3 and vitamin D in preventing lung-tissue damage of newborn rats exposed to cigarette smoke during intrauterine period / Efecto protector de omega 3 y vitamina D en la prevención del daño en el tejido pulmonar de ratas recién nacidas expuestas al humo del cigarrillo durante el período intrauterino

SUMMARY: This study aimed to investigate the toxic effects of cigarette smoke exposure on lung and the protective role of Omega 3 and Vitamin D against these toxic effects biochemically and histologically. 28 pregnant Wistar Albino rats were divided into four groups. The first group was control group; the second group was exposed to smoke of 10 cigarette by puff device 2 hours/day after pregnancy; the third group was exposed to cigarette smoke together with Omega 3 (0.5 mg/kg/day) and the fourth group was exposed to cigarette smoke together with vitamin D (42 microgram/kg/day). Finally, lung tissue sections of the newborn rats were stained with Hemotoxilen eosine and Masson tricromite. Malondialdehyde (MDA) and Fluorescent Oxidation Products (FOU) levels were measured. Fetal weights and the number of fetuses were significantly lower in the group received only cigarette smoke (both p<0.001). Histopathologically, pulmonary volume, number of developed alveols and parenchyma elasticity decreased significantly, meanwhile interstitial tissue increased, elastin and collagen did not develop adequately. Histopathologic changes significantly decreased in the group given Omega 3 and Vitamin D. Statistically, MDA and FOU levels were found to be higher in the group exposed to cigarette smoke compared to the control group, and MDA and FOU levels were lower in the group given Omega 3 along with cigarette smoke (p<0.001). Cigarette smoke caused histologically significant damage to fetal lung tissue, oxidative stress and increased MDA and FOU levels. This damage was significantly reduced with Omega 3 and Vitamine D supplementation. Omega 3 is an important antioxidant; vitamin D has no significant antioxidant effect.

RESUMEN: Este estudio tuvo como objetivo investigar los efectos tóxicos de la exposición al humo de cigarrillo en el pulmón, y el papel protector de Omega 3 y la Vitamina D contra esos efectos. 28 ratas Wistar albino preñadas fueron separadas en cuatro grupos. El primer grupo grupo control; el segundo grupo estuvo expuesto al humo de 10 cigarrillos por dispositivo de inhalación 2 horas / día después de la preñez; el tercer grupo se expuso al humo del cigarrillo junto con Omega 3 (0,5 mg / kg / día) y el cuarto grupo se expuso al humo del cigarrillo junto con vitamina D (42 microgramos / kg / día). Secciones de tejido pulmonar de las ratas recién nacidas se tiñeron con Hematoxilina Eosina y tricrómico de Masson. Se midieron los niveles de malondialdehído (MDA) y productos de oxidación fluorescente (POF). Los pesos fetales y el número de fetos fueron significativamente más bajos en el grupo que recibió solamente humo de cigarrillo (ambos p <0,001). Histopatológicamente, el volumen pulmonar, el número de alveolos desarrollados y la elasticidad del parénquima disminuyeron significativamente; mientras que el tejido intersticial aumentó y la elastina y el colágeno no se desarrollaron adecuadamente. Los cambios histopatológicos disminuyeron significativamente en el grupo que recibió Omega 3 y Vitamina D. Estadísticamente, se encontró que los niveles de MDA y POF eran más altos en el grupo expuesto al humo de cigarrillo en comparación con el grupo control, además los niveles de MDA y POF fueron más bajos en el grupo que recibió Omega 3 junto con el humo del cigarrillo (p <0,001). El humo del cigarrillo causó daños histológicamente significativos en el tejido pulmonar fetal, el estrés oxidativo y el aumento de los niveles de MDA y FOU. Este daño se redujo significativamente con los suplementos de Omega 3 y Vitamina D. El omega 3 es un importante antioxidante; la vitamina D no tiene ningún efecto antioxidante significativo.

Increased oxidative stress markers may be a promising indicator of risk for primary ovarian insufficiency: a cross-sectional case control study / Marcadores de estresse oxidativo aumentados podem ser um indicador de risco promissor para insuficiência ovariana primária: um estudo transversal caso-controle

PURPOSE: The aim of this study was to evaluate serum levels of inducible nitric oxide synthase (INOS), myeloperoxidase (MPO), total antioxidant status (TAS), and total oxidative status (TOS) in women with primary ovarian insufficiency (POI) and to compare them with healthy fertile women. We also examined the possible risk factors associated with POI.METHODS: This cross-sectional case control study was conducted in Zekai Tahir Burak Women's Health Education and Research Hospital. The study population consisted of 44 women with POI (study group) and 36 healthy fertile women (control group). In all patients, serum levels of INOS, MPO, TAS, and TOS were determined. INOS and MPO levels were measured by enzyme-linked immunosorbent assay whereas colorimetric method was used for evaluating TAS and TOS levels. Age, body mass index (BMI), obstetric history, smoking status, family history, comorbidities, sonographic findings, complete blood count values, C-reactive protein and baseline hormone levels were also analyzed. Student's t-test or Mann-Whitney U test was used to compare continuous variables between the groups; categorical data were evaluated by using Pearson χ2 or Fisher exact test, when appropriate. Binary logistic regression method was used to identify risk factors for POI.RESULTS: We found significantly elevated levels of INOS (234.1±749.5 versus133.8±143.0; p=0.005), MPO (3,438.7±1,228.6 versus 2,481.9±1,230.1; p=0.001), and TOS (4.3±1.4 versus 3.6±1.4; p=0.02) in the sera of the study group when compared to the BMI-age matched control group. However, difference in serum levels of TAS were not significant between the 2 groups (1.7±0.2 versus 1.6±0.2; p=0.15). Logistic regression method demonstrated that BMI <25 kg/m2, nulliparity, family history of POI, smoking, and elevated serum levels of INOS, MPO, and TOS were independent risk factors for POI.CONCLUSION: We found an increase in INOS, MPO, and TOS in women with POI. These serum markers may be promising in early diagnosis of POI. Further large-scale studies are required to determine whether oxidative stress markers have a role in diagnosing POI.

OBJETIVO: Avaliar os níveis séricos da sintetase nítrica induzível (INOS), da mieloperoxidase (MPO), do estado antioxidante total (EAT) e do estado oxidante total (EOT) em mulheres portadoras de insuficiência ovariana primária (IOP) e compará-las às mulheres férteis. Também examinamos os possíveis fatores de risco associados à IOP.MÉTODOS: Trata-se de estudo transversal caso-controle desenvolvido no Zekai Tahir Burak Women's Health Education and Research Hospital. A população de estudo abrangeu 44 mulheres portadoras de IOP (grupo de estudo) e 36 mulheres férteis hígidas (grupo controle). Em todas as pacientes, foram determinados os níveis séricos de INOS, MPO, EAT e EOT.Os níveis de INOS e MPO foram determinados com o uso do teste ELISA e os níveis de EAT e EOT foram determinados mediante método colorimétrico. Analisou-se também a idade, o índice de massa corporal (IMC), os antecedentes obstétricos, tabagismo, histórico familiar, comorbidades, achados sonográficos, valores completos do hemograma, proteína C-reativa e níveis hormonais basais. O teste t de Student ou o teste U de Mann-Whitney foi utilizado para comparar as variáveis contínuas entre os grupos; os dados categóricos foram avaliados pelo teste do χ2 de Pearson ou o teste exato de Fisher, conforme o caso. O método de regressão logística binária foi utilizado para identificar os fatores de risco para IOP.RESULTADOS: Encontramos níveis significativamente elevados de INOS (234,1±749,5 versus133,8±143,0; p=0,005), MPO (3.438,7±1.228,6 versus 2.481,9±1.230,1; p=0,001) e EOT (4,3±1,4 versus 3,6±1,4; p=0,02) nos soros do grupo estudo em relação ao grupo controle pareado por IMC e idade. Entretanto, as diferenças entre os níveis séricos de EAT nos dois grupos não foram significantes (1,7±0,2 versus 1,6±0,2; p=0,15). O método de regressão logística demonstrou que IMC <25 kg/m2, nuliparidade, histórico familiar de IOP, tabagismo e níveis séricos elevados de INOS, MPO e EOT foram fatores de risco independentes para IOP.CONCLUSÃO: Foram encontrados níveis aumentados de INOS, MPO e EOT em mulheres portadoras de IOP. Estes marcadores séricos podem ser promissores para o diagnóstico precoce de IOP. Novos estudos em larga escala são necessários para determinar se os marcadores de estresse oxidativo desempenham um papel no diagnóstico da IOP.

Harlequin lchthyosis: Case Report of a Rare Type of Ichthyosis.

Aims: The purpose of this study is to present a case of Harlequin fetus, which is extremely rare. Presentation of Case: A 27-year-old woman, gravida 3 para 1, was referred to the clinic with a diagnosis of preterm premature rupture of membranes. Upon ultrasound examination, a fetus with oligohydramnios at 30 weeks of pregnancy was determined. Fetal cardiac activity was present. The fetal nose and ears could not be visualized. The fetal mouth was opened wide and the lips were invisible. The wrists of the upper extremities were edematous. A cesarean section was performed, and a female fetus weighing 1140 g, 44 cm in length, and with 1st and 5th minutes Apgar scores of 6–8 was delivered. The fetal body was covered with dense keratin plaques, her eyes were in ectropion, and her nose and ears were also covered by thick keratin plaques. Eclabium lips, edematous wrists on the extremities, and the hands and feet in flexion were observed. The fetus died 24 hours later in the neonatal intensive care unit. The mother said that her second baby had the same conditions and died on postpartum day one. Discussion and Conclusion: Harlequin ichthyosis is extremely rare and is a severe congenital anomaly that has autosomal recessive inheritance patterns. Prenatal diagnosis can be based on the ultrasound findings and parents’ family history; this can contribute to our understanding of the disease and progress of pregnancy.

Spontaneous Pregnancy after Cystectomy and Urinary Diversion by Indiana Pouch Method for Congenital Bladder Exstrophy: A case Report.

Aims: To share our experience in the management of a patient of congenital bladder exstrophy, who conceived spontaneously following Indiana pouch surgery for urinary diversion. surgery for congenital bladder exstrophy, reported for antenatal care. In the first year of her life, an ineffective operation was performed for closure of her abdominal wall defect. At 10 years of age she underwent cystectomy, trygonocuteneostomy, diastasis of pubic bones were fixed and urinary diversion operation was performed by Indiana pouch method. She was followed up at the antenatal clinic of Dicle University until 38th week of pregnancy. Thereafter, an elective caesarean section was performed and a live healthy female baby was delivered. Discussion and Conclusion: Bladder exstrophy is an extremely rare congenital abnormality. Woman with bladder exstrophy and lower urinary tract reconstruction surgery may conceive spontaneously. However they have a high risk pregnancy and an elective caesarian section is advocated for delivery. Review of literature and our experience is presented.
