Ultrasonografia w przewidywaniu rozległości nacieku trofoblastu w obręb ściany jajowodu w ciąży bańkowej

Objective: Predictive factors of damage to the Fallopian tube may guide the treatment for patients with tubal pregnancy. The purpose of this study was to evaluate the predictive value of ultrasonographic findings in patients affected by ampullary pregnancy for the determination of the depth of trophoblastic infiltration into the tubal wall on histological examination. Material and methods: 38 patients with ampullary pregnancy undergoing salpingectomy were enrolled into the study. The patients were divided into two subgroups depending on their transvaginal sonography (TVS) findings; either an ectopic gestational sac containing an embryo with cardiac activity or those with a tubal ring. The ampullary pregnancies were histologically classified according to the depth of infiltration of trophoblastic tissue into the tubal wall as follows: stage I: limited to mucosa; stage II: extension to the muscularis layer; stage III: complete infiltration of the tubal wall with or without rupture of the serosa. The association between findings on TVS and stage of trophoblastic invasion, serum beta-human chorionic gonodatropin (β-hCG) levels was evaluated. Results: Although there was no significant difference among two groups in terms of histological stage of trophoblastic infiltration (p=0.257), patients in whom an embryo with cardiac activity had been identified were found to have higher percentage of stage II (47.8%) or stage III (8.7%) invasion. However, there was a significant difference in serum β-hCG levels on the day of surgery among the two groups (p=0.028). Conclusions: Ultrasonographic aspect of ampullary pregnancy is associated with depth of trophoblastic infiltration into the tubal wall and serum β-hCG levels.Cel: Czynniki predykcyjne zniszczenia jajowodu mogą być pomocne w leczeniu pacjentek z ciążą jajowodową. Celem badania była ocena wartości prognostycznej badania ultrasonograficznego u pacjentek z ciążą bańkową dla określenia rozległości naciekania trofoblastu w obręb ściany jajowodu potwierdzonego w badaniu histopatologicznym. Materiał i metoda: Do badania włączono 38 pacjentek z ciążą bańkową, u których wykonano usunięcie jajowodu. Pacjentki podzielono na dwie podgrupy pod względem różnych obrazów ultrasonograficznych; jeden z widocznym pęcherzykiem ciążowym i z zarodkiem z czynnością serca, drugi z widocznym pierścieniem jajowodowym. Ciąże bańkowe podzielono na podstawie wyniku histopatologicznego, pod względem głębokości nacieku trofoblastu w ścianę jajowodu: stopień I: ograniczone do śluzówki, stopień II: przechodzące na mięśniówkę, stopień III: całkowite nacieczenie ściany jajowodu z /bez pęknięcia surowicówki. Oceniono związek pomiędzy obrazem ultrasonograficznym, stopniem nacieczenia ściany jajowodu oraz poziomem surowiczego beta hCG. Wyniki: Nie znaleziono istotnych różnic pomiędzy badanymi grupami pod względem histologicznie ocenionego nacieku trofoblastu (p=0,257). Jednak kobiety, u których stwierdzano żywy zarodek częściej miały stopień II (47,8%) lub III (8,7%) inwazji trofoblastu. Znaleziono również istotną różnicę poziomu beta-hCG w dniu operacji pomiędzy dwoma grupami (p=0,028). Wnioski: Pewne ultrasonograficzne aspekty ciąży bańkowej są związane z głębokością inwazji trofoblastu w ścianę jajowodu oraz surowiczym beta-hC

A New Neolithic Settlement in the Upper Tigris Basin in the Light of its Knapped Stone Assemblages: Boncuklu Tarla

Neolithic Age sites in the Upper Tigris Basin have significantly increased in number over the past few years, not least because of rescue excavations related to the Ilısu Dam Project undertaken over the last decade. The resultant data has produced significant new information about this hitherto little documented period in the region. Boncuklu Tarla was discovered in 2008 during a field survey, with excavations beginning in 2012. This paper details the knapped stone assemblage from a single season of excavation, material that shed important light on the Pre- Pottery Neolithic B of the Upper Tigris Basin, adding to the information we previously knew from the important site of Çayönü

Vitamin D status among adults in the Aegean region of Turkey

<p>Abstract</p> <p>Background</p> <p>Vitamin D is a lipid-soluble hormone found in certain foods and synthesized from precursors in the skin when exposed to ultraviolet light. Vitamin D plays a critical role in bone metabolism and many cellular and immunological processes and low levels have been associated with several chronic and infectious diseases. Vitamin D status is assessed by measuring the concentration of serum 25-hydroxyvitamin D [25(OH)D]. Vitamin D deficiency is reported to be common worldwide, but little has been reported about the vitamin D status of adults in Turkey. In this cross-sectional study, we determined the prevalence of 25(OH)D deficiency in adults residing in a city in the Aegean region of Turkey.</p> <p>Methods</p> <p>A survey was conducted on a representative sample of adults over 20 years old in a non-coastal city at the end of the winter season. Of the 209 households selected by random sampling, 8.6% (n = 18) were unoccupied and 21.5% (n = 45) refused to participate. Blood samples were taken and questions about medical history, vitamin supplementation, sunlight exposure, and dietary calcium and vitamin D intake were asked in face-to-face interviews of 391 adults living in the remaining households.</p> <p>Results</p> <p>The mean serum 25(OH)D concentration was 16.9±13.09 ng/mL, with 74.9% of the subjects having 25(OH)D deficiency (<20 ng/mL), 13.8% having insufficiency (20-29.99 ng/mL), and 11.3% of the subjects having sufficient 25(OH)D (≥30 ng/mL) levels. 25(OH)D deficiency was more common among females (78.7%) than males (66.4%, p < 0.05).</p> <p>Conclusion</p> <p>Adults living in an urban, non-coastal setting in Turkey have a high prevalence of vitamin D deficiency.</p

Outcomes of high-risk breast lesions diagnosed using image-guided core needle biopsy: results from a multicenter retrospective study

PURPOSEThe clinical management of high-risk lesions using image-guided biopsy is challenging. This study aimed to evaluate the rates at which such lesions were upgraded to malignancy and identify possible predictive factors for upgrading high-risk lesions.METHODSThis retrospective multicenter analysis included 1.343 patients diagnosed with high-risk lesions using an image-guided core needle or vacuum-assisted biopsy (VAB). Only patients managed using an excisional biopsy or with at least one year of documented radiological follow-up were included. For each, the Breast Imaging Reporting and Data System (BI-RADS) category, number of samples, needle thickness, and lesion size were correlated with malignancy upgrade rates in different histologic subtypes. Pearson’s chi-squared test, the Fisher–Freeman–Halton test, and Fisher’s exact test were used for the statistical analyses.RESULTSThe overall upgrade rate was 20.6%, with the highest rates in the subtypes of intraductal papilloma (IP) with atypia (44.7%; 55/123), followed by atypical ductal hyperplasia (ADH) (38.4%; 144/375), lobular neoplasia (LN) (12.7%; 7/55), papilloma without atypia (9.4%; 58/611), flat epithelial atypia (FEA) (8.7%; 10/114), and radial scars (RSs) (4.6%; 3/65). There was a significant relationship between the upgrade rate and BI-RADS category, number of samples, and lesion size Lesion size was the most predictive factor for an upgrade in all subtypes.CONCLUSIONADH and atypical IP showed considerable upgrade rates to malignancy, requiring surgical excision. The LN, IP without atypia, pure FEA, and RS subtypes showed lower malignancy rates when the BI-RADS category was lower and in smaller lesions that had been adequately sampled using VAB. After being discussed in a multidisciplinary meeting, these cases could be managed with follow-up instead of excision

Prenatal Diagnosis of Adrenal Neuroblastoma: A Case Report with a Brief Review of the Literature

A case of adrenal cystic neuroblastoma detected at 37 weeks of gestation is reported. Postnatal ultrasonographic examination showed slightly increased in size demonstrating marked septations within the cyst. After the tumor was resected, histopathological examinations confirmed the diagnosis. The patient is developing normally at 1 year of age
