Surgical Management of Onychopapilloma, Onychomatricoma, and Subungual Osteochondroma: Case Series.

The clinical diagnosis of benign and malignant nail tumors can be difficult. Dermoscopy can provide a clue to the diagnosis but nail biopsy is the gold standard in establishing the diagnosis. Here, we report three cases of rare nail tumors, that is, onychopapilloma, onychomatricoma, and subungual osteochondroma, which were diagnosed on histopathology and managed surgically.

Risk of spontaneous preterm birth in singleton pregnancies conceived after IVF/ICSI treatment: meta-analysis of cohort studies.

OBJECTIVE: Preterm birth (PTB) is more common in pregnancies conceived by in-vitro fertilization (IVF) as compared with those conceived naturally. However, the extent to which this is attributed to spontaneous labor or to iatrogenic indications has not been determined. The aim of this study was to quantify the risk of spontaneous PTB (sPTB) in singleton pregnancies resulting from IVF or intracytoplasmic sperm injection (ICSI) treatment as compared with that in spontaneously conceived pregnancies. METHODS: An electronic search of PubMed/MEDLINE, Scopus and Web of Science to September 2017 and manual search of reference lists identified articles comparing the risk of sPTB in IVF/ICSI vs spontaneously conceived singleton pregnancies. Inclusion criteria were singleton conception with IVF/ICSI, PTB defined as delivery before 37 weeks' gestation and cohort design with clear distinction between spontaneous and indicated PTB. The primary outcome was sPTB < 37 weeks. Relevant secondary outcomes were also analyzed, including sPTB < 34 and < 32 weeks, preterm prelabor rupture of membranes, stillbirth, perinatal mortality, neonatal sepsis, respiratory distress syndrome and gastrointestinal morbidity. A meta-analysis provided the estimation of risk of sPTB in IVF/ICSI pregnancies. RESULTS: In total, 674 records were identified from the search, of which 15 met the inclusion criteria and were included in the meta-analysis. A pooled crude analysis of the primary outcome generated a total sample size of 61 677 births, including 8044 singletons conceived after IVF/ICSI and 53 633 conceived spontaneously. A pooled crude data analysis showed a significant increase in the incidence of sPTB < 37 weeks in singleton IVF/ICSI pregnancies compared with those conceived spontaneously (810/8044 (10.1%) vs 2932/53 633 (5.5%); odds ratio (OR), 1.75; 95% CI, 1.50-2.03; I2 = 39%). A subgroup analysis of studies matching for maternal age and parity confirmed the finding (OR, 1.63; 95% CI, 1.30-2.05; I2 = 33%). A pooled crude analysis of secondary outcomes showed a significant increase in the incidence of sPTB < 34 weeks in pregnancies conceived after IVF/ICSI compared with those conceived spontaneously (37/1012 (3.6%) vs 24/1107 (2.2%); OR, 1.78; 95% CI, 1.03-3.08; I2 = 6%) and did not show any significant difference for any of the other secondary outcomes analyzed. The quality of evidence, rated using the GRADE criteria, was low for the outcome sPTB < 37 weeks and very low for sPTB < 34 weeks. CONCLUSIONS: The risk of sPTB in singleton pregnancies resulting from IVF/ICSI is significantly greater than that in spontaneously conceived singletons. These findings should be interpreted with caution given the low quality of the available evidence. Copyright © 2017 ISUOG. Published by John Wiley & Sons Ltd.

Gender and the relationship between resting heart rate and left ventricular geometry.

OBJECTIVES: Heightened mortality is common to both an elevated resting heart rate and left ventricular hypertrophy (LVH). We examined the relationship between resting heart rate and left ventricular geometry. METHODS: We analysed resting heart rate and echocardiographic data on 1,685 individuals aged 25-93 years, 756 males and 929 females, without heart failure. The study population, 719 normotensives and 966 untreated hypertensives, was derived from the Egyptian National Hypertension Project (1991-94); a cross-sectional study of the prevalence of hypertension and cardiovascular risk factors in Egyptians. The mean of the last two of three heart rate readings was used to represent the resting heart rate. RESULTS: Left ventricular mass index (LVMI) was weakly inversely related to heart rate in total males (r= -0.14, P< 0.0005) and total females (r= -0.1, P= 0.007) after controlling for age and blood pressure. The relative wall thickness (RWT) of the left ventricle was positively associated with heart rate in females. Resting heart rate increased linearly from 83.8 to 89 b.p.m. (P= 0.03) from the lowest (< or = 0.33) to highest (> or = 0.47) RWT quintiles in hypertensive females after adjusting for age and blood pressure. In both those with and without LVH (defined as LVMI > 125 g/m2), hypertensive females with RWT > 0.45 compared to those with RWT < or = 0.45 had consistently higher resting heart rate (93.8 b.p.m. versus 84.2 b.p.m., P = 0.047 and 88.9 b.p.m. versus 85 b.p.m., P = 0.005, respectively) after adjusting for age and blood pressure. No such relationship was found in males. CONCLUSIONS: Among hypertensive females, an elevated resting heart rate is associated with abnormal left ventricular geometry, namely, concentric left ventricular remodelling and hypertrophy.
