Objectives: To examine the literature and synthesize the available reports for the best possible option between absorbable, nonabsorbable, and tissue adhesives in cleft lip skin closure. Design: We conducted systematic searches for randomized controlled trials and controlled clinical trials in PubMed, Cochrane, Ovid Medline, and OpenGrey databases. Identified studies were retrieved and assessed for eligibility. All statistical analyses were done with Revman, version 5.4. Interventions: The intervention considered in this systematic review were techniques of cleft lip repair using resorbable sutures, nonabsorbable sutures, medical adhesives, or any combination of these. Outcome Measures: The primary outcomes assessed in the trials had to include any combination of the following: wound healing cosmesis and wound healing complications. While secondary outcomes considered were quality of life, direct and indirect costs to patients and health services, and participant satisfaction. Results: Only 6 studies met all inclusion criteria and were selected for qualitative analysis. A more favorable wound healing cosmesis was seen when nonabsorbable suture was used in cleft lip repair compared to absorbable sutures and tissue adhesives (CI, 0.65-4.35). This advantage was overshadowed by the significantly higher prevalence of postoperative complications when nonabsorbable sutures are used. Conclusion: Although the results point to more favorable cosmesis with nonabsorbable sutures and an overall more favorable outcome with either absorbable sutures or tissue adhesives, the 6 selected studies were assessed at an unclear risk of bias; therefore, the results of this study should be interpreted with caution and regarded as low-certainty evidence.
The majority (85%) of nonsyndromic cleft lip with or without cleft palate (nsCL/P) cases occur sporadically, suggesting a role for de novo mutations (DNMs) in the etiology of nsCL/P. To identify high impact protein-altering DNMs that contribute to the risk of nsCL/P, we conducted whole-genome sequencing (WGS) analyses in 130 African case-parent trios (affected probands and unaffected parents). We identified 162 high confidence protein-altering DNMs some of which are based on available evidence, contribute to the risk of nsCL/P. These include novel protein-truncating DNMs in the ACTL6A, ARHGAP10, MINK1, TMEM5 and TTN genes; as well as missense variants in ACAN, DHRS3, DLX6, EPHB2, FKBP10, KMT2D, RECQL4, SEMA3C, SEMA4D, SHH, TP63, and TULP4. Many of these protein-altering DNMs were predicted to be pathogenic. Analysis using mouse transcriptomics data showed that some of these genes are expressed during the development of primary and secondary palate. Gene-set enrichment analysis of the protein-altering DNMs identified palatal development and neural crest migration among the few processes that were significantly enriched. These processes are directly involved in the etiopathogenesis of clefting. The analysis of the coding sequence in the WGS data provides more evidence of the opportunity for novel findings in the African genome.
Background: Odontogenic infections is a cause of mortality and morbidity in maxillofacial patients. This is largely due to resistance of organisms to antibiotics prescribed.Objectives: To isolate organisms involved in odontogenic infections and compare the sensitivity of the organisms to Ceftriaxone and Amoxicillin-Clavulanate.Methods: The causative organisms and antibiotic sensitivity were determined by the following steps: Aspiration of pus done with needle, sample of pus or exudate collected using sterile swab if aspiration was unsuccessful and specimen were placed in transport media (thioglycolatebroth) and sent immediately to microbiology laboratory for culture of organisms and antibiotic sensitivity.Results: Out of a total 55 samples taken for bacteriology, 42 (76.4%) yielded positive culture for bacteria. A total number of 21 bacteria species were identified from the positive cultures. Overall, 52% of isolated organisms were sensitive to amoxicillin-clavulanate, 70% were sensitive to Ceftriaxone while 24% were resistant to both antibiotics (Table 3). Ceftriaxone was statistically significantly more potent in inhibiting bacteria growth than amoxicillin-clavulanate (P =0.009).Keywords: Sensitivity of bacteria, odontogenic infections, ceftriaxone, amoxicillin-clavulanate.
Novel or rare damaging mutations have been implicated in the developmental pathogenesis of nonsyndromic cleft lip with or without cleft palate (nsCL ± P). Thus, we investigated the human genome for high-impact mutations that could explain the risk of nsCL ± P in our cohorts. We conducted next-generation sequencing (NGS) analysis of 130 nsCL ± P case-parent African trios to identify pathogenic variants that contribute to the risk of clefting. We replicated this analysis using whole-exome sequence data from a Brazilian nsCL ± P cohort. Computational analyses were then used to predict the mechanism by which these variants could result in increased risks for nsCL ± P. We discovered damaging mutations within the AFDN gene, a cell adhesion molecule (CAMs) that was previously shown to contribute to cleft palate in mice. These mutations include p.Met1164Ile, p.Thr453Asn, p.Pro1638Ala, p.Arg669Gln, p.Ala1717Val, and p.Arg1596His. We also discovered a novel splicing p.Leu1588Leu mutation in this protein. Computational analysis suggests that these amino acid changes affect the interactions with other cleft-associated genes including nectins (PVRL1, PVRL2, PVRL3, and PVRL4) CDH1, CTNNA1, and CTNND1. This is the first report on the contribution of AFDN to the risk for nsCL ± P in humans. AFDN encodes AFADIN, an important CAM that forms calcium-independent complexes with nectins 1 and 4 (encoded by the genes PVRL1 and PVRL4). This discovery shows the power of NGS analysis of multiethnic cleft samples in combination with a computational approach in the understanding of the pathogenesis of nsCL ± P.
