Hydrometrocolpos is one example of this disease category which is responsible for only 15% of such cases whose association with polydactyly appears to be even less common. The present study aimed to report the accounts of two neonates with cystic abdominal masses diagnosed as urinary type hydrometrocolpos secondary to urogenital sinus anomaly. Autosomal recessive disorders are characterized by vaginal atresia with hydrometrocolpos, polydactyly, congenital heart defects, and non-immune mediated hydrops fetalis. The triad of hydrometrocolpos, polydactyly, and cardiac anomaly in the two patients presented herein is strongly suggestive of a case of McKusick-Kaufman syndrome. \u0000Case report: This study reported two neonates with abdominal mass, polydactyly, and genitourinary tract malformation, with no family history. Relief of urinary obstruction by exploratory laparotomy, aspiration of fluid, and vaginal reconstruction gradually reversed the hydronephrosis and renal failure. \u0000Conclusion: It can be concluded thatin hydrometrocolpos causing urinary obstruction, decompression of hydrometrocolpos can save the kidneys.","PeriodicalId":14584,"journal":{"name":"Iranian Journal of Neonatology IJN","volume":"11 1","pages":"110-115"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86271129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It often coexists with trisomy 21 and other inborn defects. Surgery is the only way of treatment. This study aimed to investigate the relationship of CDA with early diagnosis, course of pregnancy, coexisting congenital defects, and further development of children. \u0000Methods: The data were collected using the medical history and a self-designed survey which consisted of 22 questions about the perinatal interview, coexisting inborn defects, after birth symptoms, time and methods of diagnosis, as well as the treatment outcome. \u0000Results: The surveys were sent to 31 patients who were diagnosed and treated because of CDA in our clinic between 2004 and 2019. According to the collected data, 73.7% of the patients were diagnosed prenatally with the mean time of diagnosis at 28th weeks of gestation. Moreover, 37% of the patients were preborn, and almost half of the patients had low and very low body weight. More than 2/3 of children presented coexisting inborn abnormalities. Among after birth symptoms, the most common ones were abdominal distention and lack of meconium. The majority of children were operated within 24 hours after birth. \u0000Conclusions: Prenatal diagnosis of CDA results in an earlier time of primary operation. Newborns diagnosed antenatally present fewer symptoms after the operation, fewer reoperations, and a shorter time of oral feeding toleration. The coexistence of other congenital defects increases patients’ mortality. The important factors that deteriorate the postoperative course are prematurity and low body weight. In order to avoid long-term complications, it is of utmost importance to provide follow-up.","PeriodicalId":14584,"journal":{"name":"Iranian Journal of Neonatology IJN","volume":"52 1","pages":"13-17"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85713581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The long-term consequences of severe neonatal jaundice may result in devastating neurologic sequelae, including bilirubin encephalopathy and kernicterus. Exchange transfusion has remained the most effective modality for lowering serum bilirubin concentration. The present study aimed to determine the proportion and factors associated with exchange transfusion procedure among neonates with severe jaundice in Kelantan from 2015 to 2017.Methods This cross-sectional study was carried out among neonates with severe jaundice in Kelantan between 2015 and 2017 using jaundice surveillance data from Kelantan Health State Department.Result Out of the study subjects, 45 (19.7%) neonates had severe jaundice requiring an exchange transfusion procedure. From 2015 to 2017, the prevalence of severe neonatal jaundice requiring exchange transfusion raised from 17.0%-23.7%. The significant factors associated with exchange transfusion were neonatal infection, low birth weight, ABO blood group incompatibility, and maternal blood type O.Conclusion As evidenced by the obtained results, exchange transfusion among severe neonatal jaundice in Kelantan followed an increasing trend within the study period. Associated factors leading to exchange transfusion among severe neonatal jaundice were neonatal infection, low birth weight, ABO incompatibility, and maternal blood type O. The recognition of these factors would be of great help in developing effective strategies aimed at the prevention of exchange transfusion procedure and its subsequent complications.","PeriodicalId":14584,"journal":{"name":"Iranian Journal of Neonatology IJN","volume":"696 1","pages":"7-12"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85388534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Serum creatinine is the most commonly used marker of GFR; nevertheless, it has some limitations since it can be affected by factors other than renal function. Cystatin C, another endogenous marker used to estimate GFR, is not affected by non-renal factors. The results of some studies suggest that serum cystatin C levels are more accurate tests of kidney function than serum creatinine levels. This study aimed to estimate GFR with cystatin C-based formulas among neonates and determine the correlations between these methods and the Schwartz formula. Methods: The population of this research consisted of 99 neonates whose serum creatinine and cystatin C levels were measured concurrently. Moreover, the glomerular filtration rate was estimated using the Schwartz formula and 14 cystatin C-based formulas separately. Results: Based on the findings, all GFR values based on cystatin C formulas correlated significantly with each other (p 0.05). The only cystatin C formula that yielded values correlating with the Schwartz formula was CysCrEq, which used serum cystatin C and creatinine concomitantly. Conclusion: It can be concluded that since all GFR values based on cystatin C correlated significantly and cystatin Cwasindependent of non-renal factors, cystatin C reflected the real GFR more accurately than serum creatinine. Nonetheless, further studies with gold standard techniques are required to verify the usefulness of cystatin C-based formulas.","PeriodicalId":14584,"journal":{"name":"Iranian Journal of Neonatology IJN","volume":"14 1","pages":"21-26"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75012066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
