A Study on Environmental Factors for Nonsyndromic Cleft Lip and/or Palate.

The aim of the study was to investigate the association between environmental factors and nonsyndromic cleft of the lip and/or palate (NSCL/P) in Yantai District, China. A retrospective case-control study was carried out. A total of 236 NSCL/P children were selected from Department of Oral and Maxillofacial Surgery of Yantai Stomatological Hospital between September 2013 and December 2016 as cases; 209 controls were chosen from other diagnosis in the same department during the same period. The 2 groups matched age and sex. The parents of participants were inquired regarding the risk factors, and the answers were filled in a questionnaire by physicians. Chi-square and multivariate logistic regression analysis were used to analysis the data. There was significantly increased NSCL/P risk with high maternal age (P =0.002), family history (P = 0.001), abortion history (P = 0.033), poor parental education level (P = 0.008), maternal smoking (P = 0.044), maternal alcohol (P = 0.039), common cold or fever (P = 0.035), drug use (P = 0.006), and maternal stress (P = 0.049). Reduced NSCL/P risk was found with folic acid supplementation (P = 0.005), adequate maternal age (P = 0.002), and high parental education (P = 0.001). The proper amount of folic acid, the appropriate age of childbearing, and the high education were the protective factors of NSCL/P, whereas family history, abortion history, drug use during pregnancy, maternal tobacco and alcohol, and maternal stress were the risk factors for NSCL/P in Yantai District, China.

Topical timolol maleate for superficial infantile hemangiomas: an observational study.

PURPOSE: The objective of this study was to assess the clinical effects and safety of topical timolol maleate for the management of superficial infantile hemangiomas (IHs). MATERIALS AND METHODS: From October 2012 to March 2014, 35 infants (24 girls and 11 boys; 2 to 10 months old; median age, 4.7 months) with superficial hemangiomas were treated with the local application of timolol maleate in the authors' department. Thirty-five lesions were treated using topically administrated timolol maleate every 12 hours for a mean duration of 22 weeks (range, 6 to 45 weeks). Follow-up visits were scheduled monthly and changes in tumor size, texture, and color were recorded. Treatment response was scored according to a 3-point scale system as good, partial, or no response. Adverse effects after medication were evaluated and managed accordingly. RESULTS: All patients completed treatment. Of the 35 hemangiomas, 18 (51.4%) showed a good response, 10 (31.4%) showed a partial response, and 6 (17.2%) had no response. The total response rate was 82.8% (29 of 35). Clinically, no systemic or local side effects caused by timolol maleate were observed in the patients. CONCLUSIONS: Topical timolol maleate could provide an effective and safe alternative to the systemic use of propranolol for the treatment of superficial IHs. Further prospective studies are needed to confirm the efficacy and safety of topical timolol maleate for the treatment of IHs.

Percutaneous Treatment of Large Venous Malformations in the Oral and Maxillofacial Regions Using Electrochemical Therapy Combined With Pingyangmycin.

PURPOSE: The aim of the present study was to evaluate the therapeutic outcome of using electrochemical therapy (ECT) combined with a sclerosing agent, pingyangmycin (bleomycin A5 hydrochloride; PYM), for large (>3 cm in diameter) venous malformations (VMs) in the oral and maxillofacial regions. PATIENTS AND METHODS: Thirty-five patients (15 male and 20 female; age range, 10 to 69 yr; mean age, 32 yr) with large VMs in the oral and maxillofacial region were treated with a combination of ECT and PYM under general anesthesia in the authors' department from June 2012 through May 2014. The size of the lesions varied from 3 × 3 to 12 × 15 cm. A repeated course of ECT and PYM was administered for larger VMs. The therapeutic interval was 3 months for ECT and 2 to 4 weeks for PYM. The dose of PYM for patients was 8 mg each time, and the injection concentration of PYM was 1.6 mg/mL. Patients were followed for 6 to 36 months. Therapeutic results were evaluated by clinical examination and Doppler ultrasonography before and after treatment. RESULTS: Of the 35 patients, 29 (82.9%) received 1 ECT treatment, 5 (14.3%) received 2 ECT treatments, and 1 (2.8%) received 3 ECT treatments. The number of PYM injection sessions was 1 to 5 (average, 2.5 times). According to the therapeutic criteria, the clinical outcome was excellent in 22 patients (62.9%), good in 10 patients (28.6%), and fair in 3 patients (8.5%). All patients (100%) had local swelling postoperatively that lasted approximately 1 to 2 weeks. Two patients (5.7%) had fever. No skin necrosis or nerve damage was found. CONCLUSIONS: Percutaneous treatment using ECT and PYM was a straightforward, safe, and reliable treatment modality for large VMs.

Treatment of severe infantile hemangiomas with propranolol: an evaluation of the efficacy and effects of cardiovascular parameters in 25 consecutive patients.

PURPOSE: The aim of this study was to investigate the therapeutic results and effects of propranolol on cardiovascular parameters in infants receiving systemic propranolol for complicated infantile hemangiomas (IHs), as well as to evaluate the adverse effects of propranolol throughout the course of treatment. MATERIALS AND METHODS: Twenty-five consecutive patients who presented with complicated IHs were prospectively recruited into this study between April 2012 and June 2013. All patients were treated with systemic propranolol at a dose of 1.0 to 1.5 mg/kg, and the drug was taken once per day. The length of treatment was 8.2 months on average and ranged from 6 to 12 months. The follow-up visits were scheduled monthly after discharge. Changes were recorded during the 3-day hospitalization, including systolic and diastolic blood pressures, heart rate, and blood glucose level. The treatment responses were scored according to a 4-point scale system as very good, good, mild, or no response. The adverse effects after medication administration were evaluated and managed accordingly. RESULTS: Of the 25 patients, 8 (32%) had a very good response, 11 (44%) had a good response, and 6 (24%) had a mild response. When pretreatment and post-treatment values were compared, there was no significant decrease in mean systolic and diastolic blood pressures and mean heart rate (all P > .05). The decreases in the cardiovascular parameters were not commonly associated with observable clinical symptoms. No major collateral effects were observed, and no infants were withdrawn from treatment because of side effects. CONCLUSIONS: Fluctuations from the normal ranges of cardiovascular parameters occurred frequently with the initiation of propranolol, but were clinically asymptomatic. Therefore oral propranolol was an effective and safe treatment for IHs, particularly for early intervention suitable for severe IHs.
