Patients with multiple pregnancies are at greater risk of preterm labor and delivery which is associated with increased risk of perinatal morbidity and mortality. We report a case of delayed-interval delivery of a twin pregnancy with the survival of the second fetus. The patient was hospitalized at 24 weeks and 3 days gestational age (GA) due to premature rupture of the membrane of the first amniotic sac. At 26 weeks of GA, the first fetus was born vaginally and died due to prematurity. To keep the second fetus in utero and minimize the complications, emergency McDonald cerclage was performed, and tocolysis, magnesium sulfate, betamethasone, and antibiotics were administrated. Despite our treatment at 28 weeks and 2 days gestational age, the second fetus was born via cesarean section due to breech presentation. At 10 months of corrected age, she exhibited normal development. She is now 6 years old and does not have sequel. / Çoğul gebeliği olan hastalar preterm doğum açısından artmış risk altındadır ve bu da artmış perinatal morbidite ve mortalite riskini beraberinde getirir.

Objective: This study aims to investigate the effect of prednisolone treatment on the pregnancy rates of in vitro fertilization (IVF) patients with positive thyroid autoantibodies. Methods: This study was conducted in the IVF unit of Gazi University Faculty of Medicine. It included 158 patients who underwent intracytoplasmic sperm injection using the long-term protocol of a gonadotropin-releasing hormone (GnRH) agonist that was positive for thyroid autoantibodies. Each test's reference value was used as a positive measure of anti-thyroid peroxidase and anti-TG antibodies. On the day of oocyte intake, 44 of 158 patients were started on prednisolone, and the other 114 patients were followed up without medication. Results: In the control group, pregnancy did not occur in 67.5% of the patients; it was determined that 21.1% were pregnant, 5.3% had biochemical pregnancies, 4.4% had twin pregnancies, 0.9% had triplet pregnancies, and 0.9% had ectopic pregnancies. In the extended prednisolone group, pregnancy did not occur in 56.8% of the patients; it was determined that 36.4% of them were pregnant, 4.5% had twin pregnancies, and 2.3% had biochemical pregnancies. An increase in pregnancy rate was observed in the extended prednisolone group, while a statistically significant difference was found between the groups in terms of the mean values of prednisolone according to pregnancy status (p<0.05). It was thus determined that the rate of conception increased in the extended prednisolone group compared to the controls. Conclusion: There is a strong relationship between the presence of thyroid autoantibodies and poor IVF results. The coadministration of prednisolone can improve the clinical pregnancy rate in women affected by thyroid autoimmunity. [ABSTRACT FROM AUTHOR]

Karabacak, Onur
- Abstract
İVF programında, yüksek antitiroid antikoru olan kadınlarda metilprednizolon tedavisinin gebelik oranlarına etkisi- Retrospektif vaka-kontrol çalışması. Son çalışmalarda anti-tiroid antikor pozitifliğinin asiste reprodüktif tedavide düşük gebelik oranları ile ilişkili olduğu saptanmıştır. Metilprednisolon tedavisi, lokal inflamasyonu azaltmak ve gelişmekte olan embriyo için uygun immun tolerans sağlamak için tavsiye edilmiştir. Önceki çalışmalarda prednizolon ile birlikte asetilsalisilat ya da tiroid hormon tedavi kombinasyonu araştırılmıştır. Bu çalışmanın amacı sadece metilprednisolon tedavisinin, İVF-ET tedavisi alan antitiroid antikor pozitifliği olan kadınlardaki gebelik oranlarının artışına etkisini araştırmaktır. Çalışmamızın bir alt grubu olarak tiroid hormon replasmanı alan hastalar ikincil kontrol grubu olarak ele alınmıştır. Bu retrospektif, vaka-kontrol çalışmada, antitiroid antikor normal sınırların üstünde olan 158 hasta, anti-T > 64 IU/ml ve anti TPO > 57 IU/ml olanlar, araştırmaya dahil edildi ve 3 gruba ayrıldı. Grup 1: 16mg/gün metilprednisolon tedavisi oosit toplanışından itibaren 14 gün verilen ve eğer gebelik var ise 21 gün daha 4mg/gün olarak devam edilen (n=44). Grup 2: levotiroksin-devamli + 16 mg/gün metilprednisolon tedavisi oosit toplanışından embriyo transferine kadar (ortalama 3.7 gün) alt kontrol grubu olarak alındı (n=41). Grup 3: 16 mg/gün metilprednisolon tedavisi oosit toplanışından embriyo transferine kadar (ortalama 3.6 gün) kontrol grubu olarak verilen (n=73). Araştırma sonucunda şu bulgulara ulaşıldı; Prednisolone kullanmak gebelik hizini %32 den %43 e arttirmasina ragmen, bu %11 artış istatistiksel olarak anlamlı bulunmamıştır (p=0.20). Ortalama standart olarak sadece 3.7 gün metilprednisolon alan hastalar bile normalden daha fazla gebe gebe kalıyor olabilir. Anti T seviyesi, grup 1 de 115,2 ± 121,5 ten 86,85 ± 88,2 ye düşerken, %26 anlamli bir azalma oluşturmuştur (p=0,047). Grup3 te ise 214,3±380,6 den 251,1±444,3 ve istatistiki anlamlı olarak %14 arttığı izlenmiştir (p=0.027). Anti TPO, prednisolone uzun süreli kullanan grupta 658,9±1060,8 den 539,3±907,8 ye % 18 azalmiştir (p=0.007). Grup 3 ise 313,3±682,1 ten 741,6±1343,6 istatistiki olarak %136 anlamlı arttığı izlenmiştir (p=0.000) Prednisolonun uzun süreli kullanımı olup(grup 1) gebe kalmış hastaların Anti TPO düzeyleri, grup 3 ün gebe kalamiyan grubuyla karşılaştırıldığında % 82 anlamli bir düşüş izlenmiştir. Bu bulgu prednizolon uzun süreli kullanımının Anti TPO seviyesini düşürerek gebe kalmaya yardimci oluyor olabilir. Prednisolonun uzun süreli kullanımı olup(grup 1) gebe kalmış hastaların Anti TPO seviyeleri, Anti T seviyeleri ile karşılaştırıldığında, prednisolonu uzun süre almamış ve gebe kalmamış hastaların değerlerine göre % 51.2 daha fazla baskılanmış bulunmuştur. Bu bulgu belki de asil gebelik arttirici etkinin Anti T den ziyade Anti TPO daki azalmadan kaynaklandığını göstermektedir. Ovülasyon indüksiyonu tekniklerinin indüklediği olası immün mekanizmaların antitiroid antikor düzeylerini yükselttiği ve bu antikorların implantasyonu etkilediği görülmektedir. Bu araştırma sadece kortikosteroidlerle immünterapinin, tiroid otoantikorları yüksek olan İVF-ET tedavisi alan hastalarda oto antikorlari duzeyini azaltarak klinik gebelik oranlarını arttırır hipotezini desteklemektedir. Effects of methylprednisolone therapy on pregnancy rates in women who has high level of antithyroid antibody on in vitro fertilization programme-A retrospective case-control study. In recent studies, antithyroid antibody positivity is found to be related with low pregnancy rates in assisted reproductive therapy. Methylprednisolone treatment is adviced to reduce the local inflamation and achieve moderate immune tolerance for developing embryo. In some studies methylprednisolone, acetylsalicylic acid and tyroid hormone combination treatment is investigated. The aim of this study is to investigate the effect of only methylprednisolone therapy on pregnancy rate in women who are positive for antithyroid antibody and undergo in IVF-ET. In our study, patients who are under thyroid hormone therapy included as a subgroup. A retrospective, case-kontrol study. 158 patients whose antithyroid antibodies are above normal limits; anti-T > 64 U/ml and anti TPO > 57 U/ml were included and divided into three groups. Group 1: 16 mg/day methylprednisolone treatment was given from oocyte retrieval for 14 days and continued 21 days with 4 mg/day if there is a pregnancy (n=44), Group 2: continuous levotyroxin+16 mg/day methylprednisolone from oocyte retrieval to embryo transfere (3.7 days) was given as a subgroup (n=41), Group 3: 16 mg/day methylprednisolone treatment was given from oocyte retrieval to embryo transfer day (3.7days) as a control group (n=73). As a result of this study it is observed that; using methylprednisolone increased pregnancy rates from 32% to 43%, but this 11% was not statisticaly significant (p=0.20). Patients who use methylprednisolone only 3.7 days may conceive more than normal. In group 1 Anti T levels were decreased from 115,2 ± 121,5 to 86,85 ± 88,2, and statisticaly significant 26% decrease was observed (p=0,047)*.In group 3, from 214,3±380,6 to 251,1±444,3 statisticaly significant 14% increase was observed (p=0.027). Anti TPO levels decreased 18% from 658,9±1060,8,to 539,3±907,8 in group 1 (p=0.007). In group 3 136% increase from 313,3±682,1 to 741,6±1343,6 was found statisticaly significant(p=0.000). If pregnant patients Anti TPO levels in group 1, compared with patients who aren t conceived in group 3, a 82% significant decrease was observed. This finding suggests that using prednisolone for long time may increases pregnancy rates with decreasing Anti TPO levels. If pregnant patients Anti TPO levels in group 1, compared with Anti T levels it is found to decreased 51.2%, more than patients who aren t take prednisolone long time and aren t conceived. This finding can be considered as a proof of decrease of Anti TPO levels is more helpful than decrease of Anti T levels. It seems that probable pregnancy induced immune mechanisms increase antithyroid antibody levels and these antibodies effect implantation. This study suggests that immunotherapy with only corticosteroids could improve the clinical pregnancy rates with reducing levels of autoantibody in patients whose antibody levels are high undergo IVF-ET.

Background: Our objective was to evaluate the effectiveness of clomiphene citrate (CC) vs. letrozole (L) plus human menopausal gonadotropin (hMG) in gonadotropin releasing hormone (GnRH) antagonist protocol in poor prognosis women with previous failed ovarian stimulation undergoing intracytoplasmic sperm injection (ICSI). Materials and Methods: This retrospective cohort study included cycles with CC and L plus hMG/GnRH antagonist protocols of 32 poor responders who had failed to have ideal follicles to be retrieved during oocyte pick-up (OPU) or embryo transfer (ET) at least for 2 previous in vitro fertilization (IVF) cycles with microdose flare protocol or GnRH antagonist protocol from January 2006 to December 2009. Main outcome measures were implantation, clinical pregnancy and live birth rates per cycle. Duration of stimulation, mean gonadotropin dose used, endometrial thickness, number of mature follicles, serum estradiol (E
2 ) and progesterone (P) levels on the day of human chorionic gonadotropin (hCG) administration, number of retrieved oocytes and fertilization rates were also evaluated. Results: A total number of 42 cycles of 32 severe poor responders were evaluated. Total gonadotropin consumption was significantly lower (1491 ± 873 vs. 2808 ± 1581 IU, P=0.005) and mean E2 level on the day of hCG injection were significantly higher in CC group than L group (443.3 ± 255.2 vs. 255.4 ± 285.2 pg/mL, P=0.03). ET, overall pregnancy and live birth rates per cycle were significantly higher in CC than L protocol (27.2 vs. 15%, 13.6 vs. 0% and 4.5 vs. 0%, respectively, P<0.05). Conclusion: Severe poor responders who had previously failed to respond to microdose or GnRH antagonist protocols may benefit from CC plus hMG/GnRH antagonist protocol despite high cancellation rate.

The aim of our study was to evaluate the effectiveness of resveratrol in experimentally induced endometrial implants in rats through inhibiting angiogenesis and inflammation. Endometrial implants were surgically induced in 24 female Wistar-Albino rats in the first surgery. After confirmation of endometriotic foci in the second surgery, the rats were divided into resveratrol (seven rats), leuprolide acetate (eight rats), and control (seven rats) groups and medicated for 21 d. In the third surgery, the measurements of mean areas and histopathological analysis of endometriotic lesions, VEGF, and MCP-1 measurements in blood and peritoneal fluid samples, and immunohistochemical staining were evaluated. After treatment, significant reductions in mean areas of implants ( p < 0.01) and decreased mean histopathological scores of the implants ( p < 0.05), mean VEGF-staining scores of endometriotic implants ( p = 0.01), and peritoneal fluid levels of VEGF and MCP-1 ( p < 0.01, for VEGF and p < 0.01, for MCP-1) were found in the resveratrol and leuprolide acetate groups. Serum VEGF ( p = 0.05) and MCP-1 ( p = 0.01) levels after treatment were also significantly lower in the resveratrol and leuprolide acetate groups. Resveratrol appears to be a potential novel therapeutic agent in the treatment of endometriosis through inhibiting angiogenesis and inflammation. Further studies are needed to determine the optimum effective dose in humans and to evaluate other effects on reproductive physiology. [ABSTRACT FROM AUTHOR]

The aim of this study is to compare two accepted techniques; intravenous (IV) remifentanil infusion versus its combination with paracervical block (PCB) in patients undergoing transvaginal ultrasound guided oocyte retrieval (TUGOR). One hundred unpremedicated patients were divided into two groups to receive either IV remifentanil (Group R) or IV remifentanil plus PC (Group R+PCB). After monitoring cardiopulmonary parameters, remifentanil infusion of 0.25 μg kg
-1 min-1 was started in both in groups. Additionally, when the patient felt dizzy, PCB with 10 ml 1% lidocaine was performed only in Group R+PCB followed by remifentanil infusion reduction to 0.15 μg kg-1 min-1 . Hemodynamic and respiratory parameters, adequacy of analgesia by Simple Numerical Rating Scale (SNRS), total amount of remifentanil used, pregnancy rates and side effects were recorded. Hemodynamic changes remained within clinical limits. There were clinically insignificant changes in peripheral oxygen saturation (SpO2 ) and end tidal carbon dioxide (ETCO2 ) and they returned to baseline at the end of the procedure. SNRS higher than 3 at the time of 1st ovarian puncture was observed in 6 and 0 patients, in Groups R and R+PCB, respectively (P < 0.05). The total amount of remifentanil used (μg) was significantly higher in Group R (571.8 ± 167.4) than in Group R+PCB (357.2 ± 93.6). Pregnancy rates were 60% and 48% for Groups R and R+PCB, respectively (p = 0.048). The incidence of nausea+vomiting was higher in Groups R (42%) than in Group R+PCB (20%) (P < 0.05). Addition of PCB to IV remifentanil infusion was found to be superior in pain relief during 1st ovarian puncture and reduced the incidence of nausea-vomiting with respect to IV remifentanil infusion alone.

- Abstract
The objective of this study was to determine visual quality, diagnostic accuracy, and surgical merits of small diameter laparoscopy (SDL). Thirty-seven patients were randomly selected. The indications for laparoscopy were infertility, desire for tubal sterilization or chronic pelvic pain. Patients underwent SDL, followed by conventional laparoscopy (CL) as a control under general anaesthesia. Findings at operation were compared. The mean time for diagnostic work-up was longer with SDL than CL, 11.7 ± 5.6 versus 7.6 ± 3.2 min respectively (P < 0.04). Visual quality was scored from 4 to 1 by the operator; mean visual quality, mean endometriosis score and mean adnexal adhesions score were slightly lower with SDL than CL. Sensitivity of SDL in diagnosing endometriosis, adhesions, ovarian, uterine and pouch of Douglas lesions were 71, 58, 81, 89 and 73% respectively; specificity was 100, 96, 100, 100, 100% in the same order. Suction irrigation, cyst aspiration, tissue biopsies, simple adhesiolysis, tubal ligation and cauterization were easily performed with SDL. We conclude that SDL seems a good alternative to CL in diagnosing macro-pelvic anatomy and coarse pelvic pathologies and may also be good in performing surgical procedures such as: tubal ligation, biopsies and differential diagnosis of pelvic fluids. But SDL must be used cautiously in microoriented, functional conditions such as infertility, pelvic pain, endometriosis and adhesion scoring or treatment. SDL may be regarded as a less invasive but less sensitive tool with limited surgical merits. [ABSTRACT FROM PUBLISHER]

İVF programında, yüksek antitiroid antikoru olan kadınlarda metilprednizolon tedavisinin gebelik oranlarına etkisi- Retrospektif vaka-kontrol çalışması.Son çalışmalarda anti-tiroid antikor pozitifliğinin asiste reprodüktif tedavide düşük gebelik oranları ile ilişkili olduğu saptanmıştır. Metilprednisolon tedavisi, lokal inflamasyonu azaltmak ve gelişmekte olan embriyo için uygun immun tolerans sağlamak için tavsiye edilmiştir. Önceki çalışmalarda prednizolon ile birlikte asetilsalisilat ya da tiroid hormon tedavi kombinasyonu araştırılmıştır. Bu çalışmanın amacı sadece metilprednisolon tedavisinin, İVF-ET tedavisi alan antitiroid antikor pozitifliği olan kadınlardaki gebelik oranlarının artışına etkisini araştırmaktır. Çalışmamızın bir alt grubu olarak tiroid hormon replasmanı alan hastalar ikincil kontrol grubu olarak ele alınmıştır.Bu retrospektif, vaka-kontrol çalışmada, antitiroid antikor normal sınırların üstünde olan 158 hasta, anti-T > 64 IU/ml ve anti TPO > 57 IU/ml olanlar, araştırmaya dahil edildi ve 3 gruba ayrıldı. Grup 1: 16mg/gün metilprednisolon tedavisi oosit toplanışından itibaren 14 gün verilen ve eğer gebelik var ise 21 gün daha 4mg/gün olarak devam edilen (n=44). Grup 2: levotiroksin-devamli + 16 mg/gün metilprednisolon tedavisi oosit toplanışından embriyo transferine kadar (ortalama 3.7 gün) alt kontrol grubu olarak alındı (n=41). Grup 3: 16 mg/gün metilprednisolon tedavisi oosit toplanışından embriyo transferine kadar (ortalama 3.6 gün) kontrol grubu olarak verilen (n=73).Araştırma sonucunda şu bulgulara ulaşıldı; Prednisolone kullanmak gebelik hizini %32 den %43 e arttirmasina ragmen, bu %11 artış istatistiksel olarak anlamlı bulunmamıştır (p=0.20). Ortalama standart olarak sadece 3.7 gün metilprednisolon alan hastalar bile normalden daha fazla gebe gebe kalıyor olabilir. Anti T seviyesi, grup 1'de 115,2 ± 121,5 ten 86,85 ± 88,2 ye düşerken, %26 anlamli bir azalma oluşturmuştur (p=0,047). Grup3 te ise 214,3±380,6 den 251,1±444,3 ve istatistiki anlamlı olarak %14 arttığı izlenmiştir (p=0.027).Anti TPO, prednisolone uzun süreli kullanan grupta 658,9±1060,8 den 539,3±907,8 ye % 18 azalmiştir (p=0.007). Grup 3 ise 313,3±682,1 ten 741,6±1343,6 istatistiki olarak %136 anlamlı arttığı izlenmiştir (p=0.000)Prednisolonun uzun süreli kullanımı olup(grup 1) gebe kalmış hastaların Anti TPO düzeyleri, grup 3'ün gebe kalamiyan grubuyla karşılaştırıldığında % 82 anlamli bir düşüş izlenmiştir. Bu bulgu prednizolon uzun süreli kullanımının Anti TPO seviyesini düşürerek gebe kalmaya yardimci oluyor olabilir.Prednisolonun uzun süreli kullanımı olup(grup 1) gebe kalmış hastaların Anti TPO seviyeleri, Anti T seviyeleri ile karşılaştırıldığında, prednisolonu uzun süre almamış ve gebe kalmamış hastaların değerlerine göre % 51.2 daha fazla baskılanmış bulunmuştur. Bu bulgu belki de asil gebelik arttirici etkinin Anti T'den ziyade Anti TPO daki azalmadan kaynaklandığını göstermektedir.Ovülasyon indüksiyonu tekniklerinin indüklediği olası immün mekanizmaların antitiroid antikor düzeylerini yükselttiği ve bu antikorların implantasyonu etkilediği görülmektedir. Bu araştırma sadece kortikosteroidlerle immünterapinin, tiroid otoantikorları yüksek olan İVF-ET tedavisi alan hastalarda oto antikorlari duzeyini azaltarak klinik gebelik oranlarını arttırır hipotezini desteklemektedir.Anahtar Kelimeler: Tiroid otoantikoru, Metilprednisolon, İnfertilite, İn vitro fertilizasyon. Effects of methylprednisolone therapy on pregnancy rates in women who has high level of antithyroid antibody on in vitro fertilization programme-A retrospectivecase-control study.In recent studies, antithyroid antibody positivity is found to be related with low pregnancy rates in assisted reproductive therapy. Methylprednisolone treatment is adviced to reduce the local inflamation and achieve moderate immune tolerance for developing embryo. In some studies methylprednisolone, acetylsalicylic acid and tyroid hormone combination treatment is investigated. The aim of this study is to investigate the effect of only methylprednisolone therapy on pregnancy rate in women who are positive for antithyroid antibody and undergo in IVF-ET. In our study, patients who are under thyroid hormone therapy included as a subgroup.A retrospective, case-kontrol study. 158 patients whose antithyroid antibodies are above normal limits; anti-T > 64 U/ml and anti TPO > 57 U/ml were included and divided into three groups. Group 1: 16 mg/day methylprednisolonetreatment wasgiven from oocyte retrieval for 14 days and continued 21 days with 4 mg/day if there is a pregnancy (n=44), Group 2: continuous levotyroxin+16 mg/day methylprednisolone from oocyte retrieval to embryo transfere (3.7 days) was given as a subgroup (n=41), Group 3: 16 mg/day methylprednisolone treatment was given from oocyte retrieval to embryo transfer day (3.7days) as a control group (n=73).As a result of this study it is observed that; using methylprednisolone increased pregnancy rates from 32% to 43%, but this 11% was not statisticaly significant (p=0.20). Patients who use methylprednisolone only 3.7 days may conceive more than normal. In group 1 Anti T levels were decreased from 115,2 ± 121,5 to 86,85 ± 88,2, and statisticaly significant 26% decrease was observed (p=0,047)*.In group 3, from 214,3±380,6 to 251,1±444,3 statisticaly significant 14% increase was observed (p=0.027).Anti TPO levels decreased 18% from 658,9±1060,8,to 539,3±907,8 in group 1 (p=0.007). In group 3 136% increase from 313,3±682,1 to 741,6±1343,6 was found statisticaly significant(p=0.000).If pregnant patients? Anti TPO levels in group 1, compared with patients who aren?t conceived in group 3, a 82% significant decrease was observed. This finding suggests that using prednisolone for long time may increases pregnancy rates with decreasing Anti TPO levels.If pregnant patients? Anti TPO levels in group 1, compared with Anti T levels it is found to decreased 51.2%, more than patients who aren?t take prednisolone long time and aren?t conceived. This finding can be considered as a proof of decrease of Anti TPO levels is more helpful than decrease of Anti T levels.It seems that probable pregnancy induced immune mechanisms increase antithyroid antibody levels and these antibodies effect implantation. This study suggests that immunotherapy with only corticosteroids could improve the clinical pregnancy rates with reducing levels of autoantibody in patients whose antibody levels are high undergo IVF-ET.Key words: thyroid autoantibody, methylprednisolone, infertility, in vitro fertilization 77

71 VI ÖZET Biz bu randomize prospektif çalışmamızda Endometrial Hiperplazi tedavisinde bugüne kadar pek araştırılmamış dProvera tedavi protokolüne dGnRHa eklenmesi ile ne gibi bir avantaj sağlanabileceğini araştırdık. Kliniğimize anormal uterin kanama nedeni nedeni ile başvuran ve endometrial hiperplazi tanısı almış 29 hastada; 18 hastadan oluşan bir gruba dProvera, 11 hastadan oluşan diğer gruba ise dProvera+dGnRHa tedavi protokolü uygulandı. Her iki grubun demografik özellikleri benzer idi. FSH, LH, E2' nin tedavi öncesi ve 6 aylık tedavi sonrasındaki değerlerinin değişim oranları dProvera tedavi protokolü uygulanan grup ile, dProvera+dGnRHa tedavi protokolü uygulanan grup karşılaştırıldığında, tedaviye dGnRHa eklenmesi sırası ile %38, %26, %30 ek olarak istatistiksel anlamlı azalma saptanmıştır (p>0,05). Yalnız dProvera tedavi protokolü uygulanan hasta grubunda sekretuar endometrium ve atrofik endometrium %44 oranında saptanmıştır. `dProvera+dGnRHa` tedavi protokolünün uygulandığı hasta grubunda ise 6 aylık tedavi sonundaki endometrial biyopsi sonuçları %100 atrofik endometrium olarak saptanmıştır. Tedaviye dGnRHa eklenmesi ile iyileşme %44'ten %100'e çıkarılmıştır (p

57 ÖZET Bu çalışmada, değişik etiyolojiye sahip infertil çiftlerde, PTFirı sperm parametreleri üzerine etkisi araştırılmış ve swim-up sonrası homolog IUI yapılarak elde edilen gebelik sonuçlan verilmiştir. Hasta grubu 62 çiftten oluşmuş ve bunlara toplam 88 IUI işlemi uygulanmıştır. GnRH-a, hMG veya CC ile ovulasyon indüksiyonu sonrası, beklenen ovulasyon gününde alınan semende sperm parametrelerine bakılmış ve PTFli ve PTFsiz Tyrode mediumlanyla swim-up yapılarak, 3 grup arasında sperm parametreleri karşılaşünlmıştır. PTF kullanımıyla diğer 2 gruba göre canlı sperm sayılan anlamlı ölçüde artmıştır (p O.001). Total sperm sayısı ise, yıkama öncesine göre azalırken (p < 0.001), PTFsiz gruptan fazla olduğu bulunmuştur (p < 0.001). PTF ile ve PTFsiz swim-up yapıldığında, +4 sperm sayılan yıkama öncesine göre anlamlı ölçüde artmaktadır (p < 0.001). Bu artışın PTF kullanıldığında, kullanmamaya göre daha belirgin olduğu görülmüştür (p < 0.001). Toplam 11 klinik gebelik elde edilmiş ve bunların 8'i sağlıklı çocukların doğumu ile sonuçlanmıştır. Bu bulguların ışığında, PTFin sperm parametrelerini olumlu yönde etkileyerek, fertilizasyon hızını ve gebelik hızını arttırabileceği bulunmuştur. PTF ile swim-up yaparak elde edilen ileri motil spermlerin inseminasyonu, basit, ucuz ve noninvazif bir tedavidir ve seçilmiş hastalarda yardımcı üreme teknikleri öncesi tercih edilmelidir. 58 SUMMARY In this study, the effects of pentoxifylline (PTF) on various sperm parameters were investigated in infertile couples with different etiologies and pregnancy rates were determined after homologous intrauterine insemination (IUI) following swim-up procedure. A total number of 88 IUI procedures were performed in 62 couples. After ovulation induction with GnRH-a, hMG and/or CC, husband sperm parameters after ejaculation were analyzed (T) at the expected ovulation time; then swim-up procedure was performed by using Tyrode's medium with (II) or without PTF (İH), and finally the semen parameters were compared among these 3 groups. The motile sperm counts were increased significantly by using PTF, when compared with other 2 groups (p < 0.001). After the swim-up procedure, total sperm counts were decreased in all groups; however, the decrease in total sperm count was significantly lower in PTF (+) group compared to PTF (-) group (p < 0.001). Swim-up procedure had increased the sperm counts `4+` both in PTF (+) and PTF (-) groups significantly (p < 0.001). This increase was observed to be more significant in PTF (+) group compared to PTF (-) group (p < 0.001). A total number of 1 1 pregnancies were achieved and eight of these had resulted with the birth of healthy babies. We can conclude that; PTF and swim-up have positive effects on sperm parameters and when used in combination with ovulation induction regimes pregnancy rates may further increase. Thus the proposed assisted reproductive technology is a cheap, simple and noninvasive modality that may be used before IVF regimes. 72

- Abstract
Objective: This study aims to investigate the effect of prednisolone treatment on the pregnancy rates of in vitro fertilization (IVF) patients with positive thyroid autoantibodies., Methods: This study was conducted in the IVF unit of Gazi University Faculty of Medicine. It included 158 patients who underwent intracytoplasmic sperm injection using the long-term protocol of a gonadotropin-releasing hormone (GnRH) agonist that was positive for thyroid autoantibodies. Each test's reference value was used as a positive measure of anti-thyroid peroxidase and anti-TG antibodies. On the day of oocyte intake, 44 of 158 patients were started on prednisolone, and the other 114 patients were followed up without medication., Results: In the control group, pregnancy did not occur in 67.5% of the patients; it was determined that 21.1% were pregnant, 5.3% had biochemical pregnancies, 4.4% had twin pregnancies, 0.9% had triplet pregnancies, and 0.9% had ectopic pregnancies. In the extended prednisolone group, pregnancy did not occur in 56.8% of the patients; it was determined that 36.4% of them were pregnant, 4.5% had twin pregnancies, and 2.3% had biochemical pregnancies. An increase in pregnancy rate was observed in the extended prednisolone group, while a statistically significant difference was found between the groups in terms of the mean values of prednisolone according to pregnancy status (p<0.05). It was thus determined that the rate of conception increased in the extended prednisolone group compared to the controls., Conclusion: There is a strong relationship between the presence of thyroid autoantibodies and poor IVF results. The coadministration of prednisolone can improve the clinical pregnancy rate in women affected by thyroid autoimmunity., (Copyright: © 2021 by The Medical Bulletin of Sisli Etfal Hospital.)

- Abstract
Objective: To compare the effectiveness of combined treatment of depot medroxyprogesterone acetate (MPA) with gonadotropin-releasing hormone (GnRH) analog and depot MPA alone in the management of simple endometrial hyperplasia without atypia among heavy bleeders., Study Design: Thirty- four patients with endo- metrial hyperplasia with- out atypia were selected in this prospective randomized study. Group I consisted of 15 patients who were treated with depot MPA combined with GnRH analog. Group 2 consisted of 19 patients who were treated with depot MPA alone. Injections were applied at the beginning of the study and at the end of the 3rd month. Endometrial biopsies were performed at the end of the 6th month. Main outcome measures were endometrial response and reduction of duration and amount of menstrual bleeding., Results: Total and mean duration of menstruation and total number of standardized pads used were signifi- cantly decreased in both groups. These parameters were also significantly lower in group 1 than in group 2 at the end of both the 3rd and 6th months of the study (p<0.01). Endometrial response rates were significant- ly higher in group I than in group 2 (100% vs. 44.4%, respectively, p <0.05)., Conclusion: Management of endometrial hyper- plasia with GnRH analog in addition to depot MPA provides prompt endometrial response and rapid menstru- al cycle control.

- Abstract
Autoimmune progesterone dermatitis (APD) is an uncommon cutaneous disorder characterized by exacerbations during the luteal phase of the menstrual cycle. We describe a 27-year-old woman with a recurrent skin eruption for 3 years. She had no history of exposure to synthetic progesterones. At each menses, the patient developed scaly, erythematous maculopapular lesions over the face. Intradermal skin test reaction to progesterone was positive. Progesterone sensitivity was also demonstrated by challenge test with intramuscular progesterone acetate. These features were consistent with the diagnosis of APD. Our patient was treated successfully with conjugated estrogen for 6 months. At one year follow-up, the patient had had no recurrence of facial eruption.
