To investigate the proposed synergistic teratogenic effect of use of selective serotonin receptor inhibitors (SSRI) together with sedatives or hypnotics, primarily benzodiazepines, during pregnancy.
Congenital absence of the abductor pollicis brevis is a very rare condition and is usually associated with other congenital anomalies. Here we report a case of bilateral congenital absence of the abductor pollicis brevis without any other abnormalities, which has not been previously reported. A 24-year-old Caucasian male patient presented to our clinic with flattening in the palmar region, pain and discomfort in writing, and weakness in both hands. USG and MRI revealed bilateral absence of the abductor pollicis brevis muscle. Bilateral congenital absence of the abductor pollicis brevis muscle requires no treatment due to satisfactory hand function, and results in cosmetic problems. Congenital absence of the abductor pollicis brevis muscle should be kept in mind in patients with flattening of the thenar eminences.
Objective To estimate the risks of major congenital malformations in the offspring of mothers who are underweight (body mass index (BMI) <18.5), overweight (BMI 25 to <30), or in obesity classes I (BMI 30 to <35), II (35 to <40), or III (≥40) compared with offspring of normal weight mothers (BMI 18.5 to <25) in early pregnancy.Design Population based cohort study.Setting Nationwide Swedish registries.Participants 1 243 957 liveborn singleton infants from 2001 to 2014 in Sweden. Data on maternal and pregnancy characteristics were obtained by individual record linkages.Exposure Maternal BMI at the first prenatal visit.Main outcome measures Offspring with any major congenital malformation, and subgroups of organ specific malformations diagnosed during the first year of life. Risk ratios were estimated using generalised linear models adjusted for maternal factors, sex of offspring, and birth year.Results A total of 43 550 (3.5%) offspring had any major congenital malformation, and the most common subgroup was for congenital heart defects (n=20 074; 1.6%). Compared with offspring of normal weight mothers (risk of malformations 3.4%), the proportions and adjusted risk ratios of any major congenital malformation among the offspring of mothers with higher BMI were: overweight, 3.5% and 1.05 (95% confidence interval 1.02 to 1.07); obesity class I, 3.8% and 1.12 (1.08 to 1.15), obesity class II, 4.2% and 1.23 (1.17 to 1.30), and obesity class III, 4.7% and 1.37 (1.26 to 1.49). The risks of congenital heart defects, malformations of the nervous system, and limb defects also progressively increased with BMI from overweight to obesity class III. The largest organ specific relative risks related to maternal overweight and increasing obesity were observed for malformations of the nervous system. Malformations of the genital and digestive systems were also increased in offspring of obese mothers.Conclusions Risks of any major congenital malformation and several subgroups of organ specific malformations progressively increased with maternal overweight and increasing severity of obesity. For women who are planning pregnancy, efforts should be encouraged to reduce adiposity in those with a BMI above the normal range.
The objective of the study was to examine the safety of ginger use during pregnancy on congenital malformations and selected pregnancy outcomes.
Chiari malformations are structural defects in which portions of the cerebellum are located below the foramen magnum. Of the four types of Chiari malformation, emergency physicians are most likely to encounter Type I (Chiari I). Chiari I malformations may be congenital or acquired. Congenital Chiari I malformations are most frequently encountered in the emergency department (ED) setting due to an exacerbation of subacute or chronic Chiari-related symptoms. However, acute Chiari-associated symptoms from an occult congenital or a secondary (acquired) Chiari malformation may occur.

Several reports have suggested that propylthiouracil (PTU) may be safer than methimazole (MMI) for treating thyrotoxicosis during pregnancy because congenital malformations have been associated with the use of MMI during pregnancy.
To evaluate the efficacy of laparoscopic pneumovesical ureter reimplantation for congenital malformation involving the vesicoureteral junction in children.
Silver-Russell syndrome (SRS) is characterized by pre- and post-natal growth restriction that spares head growth, feeding difficulties, and variable dysmorphic facial features without major malformations. Hypomethylation of the paternal 11p15 imprinting control region 1 (ICR1) and maternal uniparental disomy of chromosome 7 are found in 50-60% and in 5-10% of SRS patients, respectively. We report on the pre- and post-natal features of three unrelated SRS patients with unusual congenital heart defects (CHDs). Two patients born prematurely had total anomalous pulmonary venous return and died shortly after birth, and a third patient, now 4 years old, had cor triatriatum sinistrum, which was surgically corrected. In all three patients, the underlying molecular defect was 11p15 ICR1 hypomethylation. Based on a large cohort with molecularly proven SRS, the prevalence of CHD in SRS is estimated at 5.5%. We suggest that the occurrence of CHD in SRS with 11p15 ICR1 hypomethylation is not coincidental, but specific to this genotype. © 2013 Wiley Periodicals, Inc.
Large skeletal defects caused by trauma, congenital malformations, and post-oncologic resections of the calvarium present major challenges to the reconstructive surgeon. We previously identified BMP-9 as the most osteogenic BMP in vitro and in vivo. Here we sought to investigate the bone regenerative capacity of murine-derived calvarial mesenchymal progenitor cells (iCALs) transduced by BMP-9 in the context of healing critical-sized calvarial defects. To accomplish this, the transduced cells were delivered to the defect site within a thermoresponsive biodegradable scaffold consisting of poly(polyethylene glycol citrate-co-N-isopropylacrylamide mixed with gelatin (PPCN-g). A total of three treatment arms were evaluated: PPCN-g alone, PPCN-g seeded with iCALs expressing GFP, and PPCN-g seeded with iCALs expressing BMP-9. Defects treated only with PPCN-g scaffold did not statistically change in size when evaluated at eight weeks postoperatively (p = 0.72). Conversely, both animal groups treated with iCALs showed significant reductions in defect size after 12 weeks of follow-up (BMP9-treated: p = 0.0025; GFP-treated: p = 0.0042). However, H&E and trichrome staining revealed more complete osseointegration and mature bone formation only in the BMP9-treated group. These results suggest that BMP9-transduced iCALs seeded in a PPCN-g thermoresponsive scaffold is capable of inducing bone formation in vivo and is an effective means of creating tissue engineered bone for critical sized defects.
