Objectives: This meta-analysis aimed to evaluate congenital malformations in infants conceived by assisted reproductive techniques (ART), compared with infants conceived spontaneously. Methods: In this study, available resources searched to find relevant articles included PubMed, ScienceDirect, Scopus, Google Scholar, Cochrane, ProQuest, Iranmedex, Magiran, and Scientific Information Database. After extracting the necessary information from evaluated articles, meta-analysis on the articles' data was performed using Stata version 11.2. Results: In this study, from a total of 339 articles, extracted from the initial investigation, ultimately 30 articles were selected for meta-analysis that assessed the use of ART on the risk of congenital abnormalities and some birth complications on 5 470 181 infants (315 402 cases and 5 154 779 controls). The odds ratio (95% confidence interval [CI]) for low birth weight was 1.89 (95% CI, 1.36 to 2.62), preterm labor 1.79 (95% CI, 1.21 to 2.63), cardiac abnormalities 1.43 (95% CI, 1.27 to 1.62), central nervous system abnormalities 1.36 (95% CI, 1.10 to 1.70), urogenital system abnormalities 1.58 (95% CI, 1.28 to 1.94), musculoskeletal disorders 1.35 (95% CI, 1.12 to 1.64), and chromosomal abnormalities in infants conceived by ART was 1.14 (95% CI, 0.90 to 1.44), which were all statistically significant, except chromosomal abnormalities. Conclusions: The risk of congenital abnormalities and some birth complications were significantly higher in ART than normal conception, while chromosomal abnormalities were not; therefore, the application of ART should be selected individually for patients by detailed assessment to reduce such risks in the population.

Patients with congenital heart diseases (CHD) are confronted with early- and late-onset complications, such as conduction disorders, arrhythmias, myocardial dysfunction, altered coronary flow, and ischemia, throughout their lifetime despite successful hemodynamic and/or anatomical correction. Rhythm disturbance is a well-known and increasingly frequent cause of morbidity and mortality in patients with CHD. Predisposing factors to rhythm disturbances include underlying cardiac defects, hemodynamic changes as part of the natural history, surgical repair and related scarring, and residual hemodynamic abnormalities. Acquired factors such as aging, hypertension, diabetes, obesity, and others may also contribute to arrhythmogenesis in CHD. The first step in evaluating arrhythmias in CHD is to understand the complex anatomy and to find predisposing factors and hemodynamic abnormalities. A practical stepwise approach can lead to diagnosis and prompt appropriate interventions. Electrophysiological assessment and management should be done with integrated care of the underlying heart defects and hemodynamic abnormalities. Catheter ablation and arrhythmia surgery have been increasingly applied, showing increasing success rates with technological advancement despite complicated arrhythmia circuits in complex anatomy and the difficulty of access. Correction of residual hemodynamic abnormalities may be critical in the treatment of arrhythmia in patients with CHD.

Townes-Brocks syndrome (TBS) is a rare autosomal dominant congenital disorder caused by mutations in the $SALL1$ gene. Its signs and symptoms overlap with other genetic syndromes, including VACTERL association, Pendred syndrome, Baller-Gerold syndrome, and cat eye syndrome. Structural vertebral abnormalities, hypoplasia of the thumb, and radial bone abnormalities, which are not usually associated with TBS, help in the differential diagnosis of these syndromes. We report the case of a family whose members were diagnosed with TBS with congenital hypothyroidism and had a novel $SALL1$ gene mutation.

Genetic imbalances are a major cause of congenital and developmental abnormalities. We report the first case of a 3p26 microdeletion and 5q35.2q35.3 microduplication in a newborn with multiple congenital anomalies evaluated using chromosomal microarray analysis (CMA) and fluorescence in situ hybridization (FISH). The patient was born at 30 weeks and 2 days of gestation with a body weight of 890 g. He had symmetric intrauterine growth restriction, microcephaly, facial dysmorphism (hypertelorism, blepharophimosis, mild low-set ears, high-arched palate, and micrognathia), and right thumb polydactyly. Echocardiography revealed an atrial septal defect and patent ductus arteriosus. Furthermore, CMA revealed a concurrent microdeletion in 3p26 and a microduplication in 5q35.2q35.3. FISH analysis showed that these genetic changes resulted from a translocation mutation between chromosomes 3 and 5. The patient's mother had mild intellectual disability, short stature, and facial dysmorphism, while his father had a normal phenotype. However, parental FISH analysis revealed that the asymptomatic father carried a balanced translocation of chromosomes 3p26 and 5q35. CMA and FISH tests are useful for diagnosing neonates with multiple congenital abnormalities. Further parental genetic investigation and proper genetic counseling are necessary in cases of chromosomal abnormalities inherited from parental balanced translocations.

Three neonates with congenital diaphragmatic eventration underwent intrathoracic operation had marked improvements in symptoms postoperatively. Two were one day of ages, one was 1 month of age, and they were all female and had other congenital abnormalities of lung hypoplasia, cleft palate, nasal polyps and neonatal hepatitis. The right diaphragm was more affected than left as 2:1. The repair for diaphragmatic eventration was performed successfully by plication of remnant diaphragm, and there were no complications postoperatively.

The authors observed the two cases of Rieger's syndrome in 21-year-old male and 13-year-old female with a chief complaint of Partial anodontia of permanent teeth on both jaws. We had done the laboratory and ophthalmic examinations and had taken radiographs. Final diagnosis was established as Rieger's syndrome. We obtained the results as follows, 1. There was no peculiar hereditary tendency in them. 2. The patients had no disturbance of general physical activity and mentality. 3. The male patient had pseudoprogenathism, concave profile, congenital missing on upper anterior and second premolar teeth, and conical shaped crown of upper len celral incisor. The female patient had also pseudoprognathism, concave profile, thickened upper labial frenum, decreased upper dental arch width, congenital missing on upper anterior teeth, and delayed eruption of second premolars. 4. The ophthalmic symptoms that were ins abnormalities, decreased visual acuity, and increased intraocular pressure were present. 5. The abnormalities except dental and ophthalmic abnormalities were not round.

Congenital esophageal stenosis is a rare disease in childhood. By virtue of its complex embryological development, the esophagus is the site of many congenital abnormalities. Congenital Esophageal stenosis is one tenth as rare as tracheoesophageal fistula with esophageal atresia and is very rare in the cervical esophagus, which mostly occurred below mid-esophagus. Congenital esophageal web may be caused by the resorption failure of the epithelium following the vacuolization stage in embryonic development in the esophagus. Recently, we experienced 1 cases of congenital esophageal web, as the symptoms of life-long dysphagia. According to her history of dysphagia, radiologic and clinical findings, her esophageal stenosis was considered as congenital. For dilatation and relief of dysphagia, she underwent the Heineke-Mikulicz type of esophagoplasty. The results of surgical treatment were relatively good without any clinical events. So we reported it with its literature review.

Congenital syngnathia refers to the fusion of bony tissues, a rare disorder with only 41 cases reported in the international literature from 1936 to 2009. The occurrence of syngnathia without any other associated systemic disease or congenital anomaly is extremely rare. This report presents a case of congenital syngnathia with unilateral maxillomandibular bony adhesion without any other oral or maxillofacial anomaly. No recommended protocol for surgery exists due to the rarity of the disorder. There is a very low survival rate for the few patients who have forgone surgical management. This case describes a 74-year-old female patient who was suffering from limitation of mouth opening and was subsequently diagnosed with congenital syngnathia. The surgical staff performed separation surgery and reconstructed the malformed oral vestibule and cheek using the radial forearm free flap operation.

Congenital deficiency of the anterior cruciate ligament (ACL) is a rare disorder that has been reported in association with other knee dysplasia like as congenital knee dislocation. congenital short femur, congenital absence of menisci, congenital ring meniscus, and thrombocytopenia-absent radius syndrome. There has been no published explanation about the etiology of bilaeral ACL deficiencies without other abnomality. The patient of congenital ACL deficiency must be carefully inspected about combined anomaly. Those efforts may be helful in treatment or ACL deficient patients and evaluation of pathophysiology or ACL deficiency. However there has not been a ruptured congenital deficiency of the ACL without other dysplasia or the knee and other congenital skeletal abnomalities. We reported a case of symptomatic bilateral congenital deficiencies of the ACL which have not been associated with other skeletal abnormalities.

Abnormalities of the posterior arch, including congenitally absent cervical pedicle and cervical spondylolysis, are rare entities that are usually found incidentally on neck radiographs. It is important to recognize these characteristic radiological features because their radiographic appearance may cause them to be confused with more serious entities such as fractures, locked facets, and tumor-induced bony erosions. Also, it is important to distinguish these abnormalities from similar pathologies to prevent the use of inappropriate treatment We report the relevant clinical and radiological findings seen in three cases of posterior arch defect after trauma with review of pertinent literature.
