Cleft lip/palate: incidence of prenatal diagnosis in Glasgow, Scotland, and comparison with other centers in the United Kingdom

Prenatal detection of orofacial clefts in Denmark from 2009 to 2018

OBJECTIVE

To investigate the overall and type-specific prenatal detection rates (DRs) of orofacial clefts in a national cohort in Denmark.

METHODS

This study was based on data from the Danish Fetal Medicine Database and included all fetuses and children from singleton pregnancies diagnosed with an orofacial cleft prenatally and/or postnatally between 2009 and 2018. The types of cleft included unilateral, bilateral or median cleft lip (CL); unilateral, bilateral or median cleft lip with secondary cleft palate (CLP); and cleft palate (CP). The clefts were grouped as cleft lip with or without cleft palate (CL(P)) or as all clefts (including CP). All cases with discordance between prenatal and postnatal diagnoses were validated in the local patient files (Astraia). Cases without prenatal validation of the postnatal diagnosis were marked as undetected. Postnatally diagnosed cases with a strong prenatal suspicion of a cleft but without an International Classification of Diseases-10 code were registered as prenatally detected. Termination of pregnancy and intrauterine death were registered as true positives even if no autopsy could be performed. Liveborn cases with a prenatal diagnosis but without a postnatal validation were excluded.

RESULTS

A total of 994 cases were included in the study, of which 933 were liveborn. The prevalence of orofacial cleft was 1.6 per 1000 live births. There were no differences in the baseline characteristics between detected and undetected cases. The DR for CL(P) was 71.7% (95% CI, 64.8-78.9%), with an increase from 60.0% in 2009 to 73.0% in 2018 (P = 0.018). The type-specific DRs for the entire period were 56.4% (95% CI, 45.0-67.6%) for unilateral CL; 76.6% (95% CI, 71.7-82.9%) for unilateral CLP; 70.5% (95% CI, 52.1-87.6%) for bilateral CL; 82.3% (95% CI, 70.6-93.6%) for bilateral CLP; 0% (0/6) for median CL; 75.0% (3/4) for median CLP; and 3.3% (95% CI, 0.6-5.7%) for CP. A total of 20.9% (208/994) of the cases had associated findings, of which 33.2% (69/208) were genetic aberrations.

CONCLUSIONS

The DR for CL(P) has improved in Denmark over the last decade. The DR for CLP is high, with the highest DR for bilateral CLP. However, prenatal detection of CP remains a challenge. © 2023 The Authors.

Parental response to the feeding behavior problems in children with cleft lip and palate: A systematic review

OBJECTIVE

To assess and analyze the global status of parental responses to feeding problems in patients with cleft lip and palate (CLP) and to provide recommendations for future research.

DESIGN

A priori protocol was formulated according to PRISMA guidelines and registered. The predefined search strategy was used in established search engines up to July 27, 2020 without any restriction of language or year of publication. Studies evaluating the parental responses to feeding problems in patients with CLP were included. The data extraction was performed with a self-designed form, and risk of bias (ROB) was assessed.

RESULTS

Out of 27 identified papers, eight studies could be included. Most were from Europe, conducted between 1994 and 2020, and had utilized valid and reliable questionnaires. The included studies showed moderate or low ROB. The majority of the studies reported parental dissatisfaction with the knowledge provided. The presence of anxiety and low self-esteem among parents was also highlighted.

CONCLUSIONS

There was general consensus regarding lack of medical advice and support for CLP families, along with the presence of anxiety and low self-esteem among parents. Well-designed studies from different regions of the world must be conducted in the future for an accurate global picture to be presented.

The dual role of ROS, antioxidants and autophagy in cancer

In this issue of the Biomedical Journal, we highlight a review revealing that the effect of autophagy, reactive oxygen species, and antioxidants in cancer may be a question of timing and context. We also discuss original research showing that the prevalence of cleft lip with or without palate in Taiwan has declined over the past 20 years, and what this might mean in terms of trends in abortion. Finally, we also learn about risk factors for recurrent hospital-acquired infection with multi-drug resistant bacteria, and the value of dental screening for patients with tinnitus.

Time trend of incidence rates of cleft lip/palate in Taiwan from 1994 to 2013

Background

This study was to estimate the incidence rate of cleft lip and/or cleft palate (CL/P) in Taiwan from 1994 to 2013, and to assess the time trend over these years.

Methods

Retrospective data analysis was performed on records of all newborns with CL/P treated at Chang Gung Craniofacial Center, the only treatment center for CL/P in Taiwan, from 1994 to 2013. Three-year moving average rates were computed and linear regression was used to explore the annual average percentage change.

Results

From 1994 to 2013, 7282 newborns with CL/P were identified, corresponding to an annual rate of 1.48‰ (95% confidence interval (CI) = 1.45‰–1.52‰). There was a significant decline of rate of cleft lip with or without cleft palate (CL ± P) (−2.9% ± 0.2%, p < 0.0001) but slightly increase of rate of cleft palate (CP) only (+0.2% ± 0.07%, p = 0.004).

Conclusion

From 1994 to 2013, the annual rate of incidence of CL/P was 1.48‰ in Taiwan. The 2.9% annual decline of the rate was mainly from the CL ± P group, not the CP group.

The cleft team social worker

The birth of a child with significant medical problems poses challenges for most families. Congenital orofacial clefting is a common condition affecting families worldwide. Orofacial clefting requires long-term medical care and can affect multiple body systems. Having a child with a chronic medical condition such as cleft lip or palate creates many psychosocial ramifications for a family. This article describes the importance of medical social work involvement in the coordinated care for children with cleft lip and palate. Specific cases spanning prenatal care through adolescence are used to highlight the variety of complex psychosocial situations encountered in the multidisciplinary cleft team setting.

Epidemiologic Research on Malformations Associated with Cleft Lip and Cleft Palate in Japan

To investigate malformations associated with cleft lip and cleft palate, we conducted surveys at neonatal intensive care units (NICUs) and other non-NICU facilities and to determine whether there are differences among facilities. The regional survey investigated NICU facilities located in Oita Prefecture, including 92 patients with cleft lip and palate (CLP) or cleft palate (CP) that occurred between 2004 and 2013, and the national survey investigated oral surgery, plastic surgery, and obstetrics and gynecology facilities located in Japan, including 16,452 patients with cleft lip (CL), CLP, or CP that occurred since 2000. The incidence per 10,000 births was 4.2, 6.2, and 2.8 for CL, CLP, and CP, respectively, according to the national survey, and 6.3 and 2.9 for CLP and CP, respectively according to the regional survey. These results indicated comparable incidences between the two surveys. In contrast, when the survey results on malformations associated with CLP and CP according to the ICD-10 classification were compared between the national survey conducted at oral surgery or plastic surgery facilities and the regional survey conducted at NICU facilities, the occurrence of associated malformations was 19.8% vs. 41.3% for any types of associated malformation, 6.8% vs. 21.7% for congenital heart disease, and 0.5% vs. 16.3% for chromosomal abnormalities. These results indicated that the incidences of all of these associated malformations were significantly greater in the survey conducted at NICU facilities and similar to the findings from international epidemiological surveys. When comparing the survey conducted at obstetrics facilities vs. NICU facilities, the occurrence of associated malformations was similar results as above. The incidence of CLP and CP was not different between surveys conducted at NICU facilities vs. non-NICU facilities; however, when conducting surveys on associated malformations, it is possible to obtain accurate epidemiological data by investigating NICU facilities where detailed examinations are thoroughly performed.
