The impact of cleft lip and palate on the quality of life of young children: A scoping review

Yusof MS, Mohd Ibrahim H

Med J Malaysia, 2023 Mar;78(2):250-258.
PMID: 36988538

INTRODUCTION: Cleft lip and palate (CL/P) are among the most common congenital abnormalities. The purpose of the present study was to review the literature relating to the quality of life (QoL) in young patients with cleft lip and/or palate (CL/P) and to identify the specific aspect of QoL in young patients with CL/P that is mostly affected. Other associated variables within studies that may have an impact on QoL were also identified.
MATERIALS AND METHODS: Systematic searches of PubMed, Scopus and Web of Science databases were conducted. Independent reviewers screened the title, abstract and full texts according to predetermined inclusion and exclusion criteria. Articles published in English from January 2012 to March 2022 reporting the QoL of non-syndromic young patients aged 7-18 years with CL/P were included. Review articles and articles reporting the psychological adjustment of parents or other family members with CL/P were excluded.
RESULTS: 975 publications were identified, of which 20 studies met our inclusion criteria. The majority of studies reported that the CL/P condition has a negative impact on the QoL. Psychological health, functional well-being, socialemotional well-being and school environment are domains that are affected. Compared with typically developing young patients, those with CL/P had lower QoL scores even though QoL was assessed using different instruments across studies. The impact of CL/P on overall QoL scores varied by age but not gender or cleft type.
CONCLUSION: Our reviews had shown the presence of CL/P negatively affects the QoL of young patients. Psychological health is the most affected QoL domain. Understanding the impacted domain will help in planning and delivering better health care for individuals with CL/P and reducing the stigma commonly associated with CL/P. Future studies should target intervention on psychological health and consider resilience factors towards positive adjustment.

Thiourea derivatives display a broad spectrum of applications in chemistry, various industries, medicines and various other fields. Recently, different thiourea derivatives have been synthesized and explored for their anti-microbial properties. In this study, four carbonyl thiourea derivatives were synthesized and characterized, and then further tested for their anti-amoebic properties on two potential pathogenic species of Acanthamoeba, namely A. castellanii (CCAP 1501/2A) and A. polyphaga (CCAP 1501/3A). The results indicate that these newly-synthesized thiourea derivatives are active against both Acanthamoeba species. The IC50 values obtained were in the range of 2.39-8.77 µg·mL⁻¹ (9.47-30.46 µM) for A. castellanii and 3.74-9.30 µg·mL⁻¹ (14.84-31.91 µM) for A. polyphaga. Observations on the amoeba morphology indicated that the compounds caused the reduction of the amoeba size, shortening of their acanthopodia structures, and gave no distinct vacuolar and nuclear structures in the amoeba cells. Meanwhile, fluorescence microscopic observation using acridine orange and propidium iodide (AOPI) staining revealed that the synthesized compounds induced compromised-membrane in the amoeba cells. The results of this study proved that these new carbonyl thiourea derivatives, especially compounds M1 and M2 provide potent cytotoxic properties toward pathogenic Acanthamoeba to suggest that they can be developed as new anti-amoebic agents for the treatment of Acanthamoeba keratitis.

Bukit Merah Reservoir is the main potable and irrigation water source for Kerian District, Perak State, Malaysia. For the past two decades, the reservoir has experienced water stress. Land-use activities have been identified as the contributor of the sedimentation. The Soil and Water Assessment Tool (SWAT) was used to simulate and quantify the impacts of land-use change in the reservoir watershed. The SWAT was calibrated and two scenarios were constructed representing projected land use in the year 2015 and hypothetical land use to represent extensive land-use change in the catchment area. The simulation results based on 17 years of rainfall records indicate that average water quantity will not be significantly affected but the ground water storage will decrease and suspended sediment will increase. Ground water decrease and sediment yield increase will exacerbate the Bukit Merah Reservoir operation problem.

INTRODUCTION: Children and adolescents with neurogenic bladder often need clean intermittent catheterization (CIC) over a long period. Our study aimed to identify factors that affect CIC compliance and to determine if CIC compliance affected short-term urological outcomes among patients in Malaysia.
STUDY DESIGN: 50 patients aged 2-18 years who perform CIC were included in this cohort study. Patient compliance with CIC was evaluated using the validated Intermittent Catheterization Adherence Scale (ICAS). CIC difficulties were assessed using the validated Intermittent Catheterization Difficulty Questionnaire (ICDQ). Data was obtained on patients' co-morbidity, caregiver factors, socio-economic factors, CIC technique, access to catheters and facilities, urinary tract infections, incontinence, urology tests and treatment. Statistical analysis was performed.
RESULTS: Mean age was 6.68 ± 4.34 years. 32 (64%) patients commenced CIC within the first month of life. Mean daily CIC frequency was 4.70 ± 1.33.30 (60%) participants showed strong adherence to CIC. 39 (78%) participants were able to catheterize with no or minor difficulties. Pain (6, 12%), transient blocking sensation (6.12%), and urinary incontinence (3, 6%) were the predominant difficulties encountered. CIC performed by caregiver was associated with improved adherence compared to patient self-catheterization (p = 0.039). The mean age of participants who self-catheterized was 10.7 ± 3.7 years. Strong adherence was also observed among patients who purchased their own CIC catheters (p = 0.007). Participants with lower ICDQ score were more likely to be compliant with CIC (p = 0.007). CIC adherence was not affected by patient's age, gender, co-morbidity, mobility, caregiver factors, socio-economic factors, and age at initiation of CIC. There was no significant association between CIC adherence and febrile urinary tract infections, upper tract deterioration, and bladder stones at 6 months follow-up.
DISCUSSION: There is lower CIC adherence when a child begins to self-catheterize and healthcare providers should be alert during this period of transition. Though most patients with spina bifida have decreased urethral sensation, some patients do experience significant pain during CIC which may impact their compliance. These patients would need a review of their catheterization techniques to improve adherence. The limitations of our study are its modest sample size from a single center and short study period. Our study provides insights into the feasibility of instituting CIC in developing countries.
CONCLUSION: Strong CIC adherence was observed among patients who were catheterized by their caregiver, purchased their own CIC catheters, and encountered minimal difficulties during catheterization. CIC adherence had no effect on short-term urological outcomes.

This study explores the perceptions of facilitators, barriers to communication and strategies in Malaysian school-aged children with non-syndromic cleft lip and palate (CL/P), parents, and teachers. Fourteen children with non-syndromic CL/P aged 7 to 12 years, their parents (n = 16), and their teachers (n = 10) were recruited via purposive sampling. Participants were selected based on resilience scores (RS-10; (Wagnild, 2015) distinguishing low (<34) from high resilience (35-40) (Wagnild, 2015). Individual in-depth interviews were conducted online and evaluated qualitatively. The analyses were conducted utilising the guidelines by Braun and Clarke (2006). Inductive thematic analysis was performed. Facilitators for communication identified by children, parents and teachers were the child's personal attributes, common interests, and helping others. Barriers that were identified were unfamiliar conversation partners, and insensitive comments or questions. Children used passive (e.g. ignored) and active (e.g. retorted, explained the condition) strategies to address social communication issues. Children with high resilience responded more actively than children with low resilience. Strategies that were described by the parents included accepting the child, empowering themselves, following the cleft management plan, and empowering the child. Teachers adopted general approaches such as giving encouragement, increasing confidence, and teaching empathy. The presence of face masks was perceived as both a facilitator and a barrier to communication. The study provides information on challenges encountered and coping mechanisms used by children with non-syndromic CL/P, their parents and their teachers. This knowledge may help the development of targeted interventions to support the communication of children with non-syndromic CL/P in school.

In the title mol-ecule, C23H22N2OS, the di-phenyl-acetyl and ethyl-benzene groups adopt a trans-cis conformation, respectively, with respect to the S atom across the (S=)C-N bonds. This conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond and a weak C-H⋯S hydrogen bond. The ethyl-substituted benzene ring forms dihedral angles of 87.53 (15) and 73.94 (15)° with the phenyl rings. In the crystal, N-H⋯O hydrogen bonds link mol-ecules into chains along [100]. A weak C-H⋯π inter-action is also observed.

The title mol-ecule, C22H17F3N2OS, adopts a trans-cis conformation with respect to the positions of the carbonyl and tri-fluoro-methyl-benzene groups against the thio-carbonyl group across the C-N bonds. The mol-ecular structure is stabilized by an intra-molecular N-H⋯O hydrogen bond with an S(6) ring motif. The tri-fluoro-methyl-substituted benzene ring forms dihedral angles of 66.05 (9) and 47.19 (9)° with the terminal phenyl rings and is twisted from the O=C-N-(C=S)-N carbonyl-thio-urea plane [maximum deviation = 0.0535 (12) Å], making a dihedral angle of 63.59 (8)°. In the crystal, N-H⋯O and C-H⋯F hydrogen bonds link the mol-ecules into a layer parallel to the bc plane. A C-H⋯π inter-action is also observed.

PMID: 23795124 DOI: 10.1107/S1600536813013354

In the title compound, C25H26N2OS, the diethyl-substituted benzene ring forms dihedral angles of 67.38 (9) and 55.32 (9)° with the terminal benzene rings. The mol-ecule adopts a trans-cis conformation with respect to the orientations of the di-phenyl-methane and 1,3-di-ethyl-benzene groups with respect to the S atom across the C-N bonds. This conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, pairs of N-H⋯S hydrogen bonds link the mol-ecules into inversion dimers, forming R 2 (2)(6) loops. The dimer linkage is reinforced by a pair of C-H⋯S hydrogen bonds, which generate R 2 (2)(8) loops. Weak C-H⋯π and π-π [centroid-centroid seperation = 3.8821 (10) Å] inter-actions also occur in the crystal structure.
