The Impact of Pre-surgical Orthopedics Appliances (PSOAs) in Bilateral Cleft Lip and Palate (BCLP) Patients

INTRODUCTION: Acceptable maxillary growth in bilateral cleft lip and palate (BCLP) is difficult to achieve. Pre-surgical orthopedic treatment aims at the reduction of cleft size by guiding growth and functional rehabilitation. The objective of this study was to evaluate the impact of Pre-surgical Orthopedics Appliances (PSOAs) on facial growth in BCLP. MATERIALS AND METHODS: Consented subjects were patients who were treated in Hospital Universiti Sains, Malaysia, and Hospital Raja Perempuan Zainab II. Ages of patients ranged from 7 to 21 years of age with non-syndromic cleft and no associated anomalies. A lateral cephalogram was taken and data collected was analyzed to compare the facial growth of BCLP with and without PSOA and between active and passive PSOA. RESULTS: The study sample comprised of 52 BCLP patients with 26 having PSOA and 26 did not having PSOA. Among these patients, those who had PSOA had significant shorter length of PNS-ANS (3.69 mm; p= 0.04) and Co-A (8.38 mm; p=0.04) compared to those who did not have PSOA. However, there were no significant difference in the length measurements between passive and active PSOA users. CONCLUSION: The usage of PSOA gives a shorter maxillary length in the facial growth of bilateral cleft patients. This study proved the effectiveness of PSOA on facial growth of cleft patients in local population.

The Impact of Abdominoplasty vs Non-abdominoplasty on Weight Loss in Bariatric and Non-bariatric Malaysian Patients: A Multicentre Retrospective Study

Background and aims

Weight loss associated with abdominoplasty remains controversial as to whether it is contributed by the procedure alone, or if there are other patient factors. Therefore, we evaluated the relationship between weight loss in pre- and post-abdominoplasty and compared the weight loss of those who do not undergo abdominoplasty in bariatric and non-bariatric patients.

Methods

This study measured weight changes at designated time points in four different groups comprising 98 patients. The groups were abdominoplasty after bariatric surgery (group A), patients with abdominoplasty alone (B), bariatric surgery alone (group C), and diet alone (group D). Results are compared within and between the groups.

Results

Patients in groups A and B (patients who had abdominoplasty regardless with or without bariatric surgery) had a significant weight loss after six months (mean difference=10.70kg, 95% CI=4.05, 17.34, p<0.001) compared to pre abdominoplasty weight. Patients in group B were statistically significant (mean difference=4.01kg, 95% CI=0.92, 7.10, p=0.007) with 3.60kg weight reduction (4.59%). Patients in group A had clinically significant weight reduction (4.45kg, 5.14%) but it was not statistically significant (p>0.05) and had no significant additional weight reduction as compared to non-abdominoplasty (group C) patients (p=0.650). Patients in group C had a statistically significant difference from those in group D (F [1.00, 48.00] = 8.56, p=0.005) with an average weight loss of 3.60kg (4.59%) vs 2.56kg (2.8%) respectively.

Conclusions

All patients with abdominoplasty had significant weight loss after six months. Bariatric patients did not experience significant additional weight loss with abdominoplasty. Weight reduction after abdominoplasty alone was greater than diet alone. 

Whole Genome Sequencing Analysis of Salmonella enterica Serovar Typhi: History and Current Approaches

In recent years, the advance in whole-genome sequencing technology has changed the study of infectious diseases. The emergence of genome sequencing has improved the understanding of infectious diseases, which has revamped many fields, such as molecular microbiology, epidemiology, infection control, and vaccine production. In this review we discuss the findings of Salmonella enterica serovar Typhi genomes, publicly accessible from the initial complete genome to the recent update of Salmonella enterica serovar Typhi genomes, which has greatly improved Salmonella enterica serovar Typhi and other pathogen genomic research. Significant information on genetic changes, evolution, antimicrobial resistance, virulence, pathogenesis, and investigation from the genome sequencing of S. Typhi is also addressed. This review will gather information on the variation of the Salmonella enterica serovar Typhi genomes and hopefully facilitate our understanding of their genome evolution, dynamics of adaptation, and pathogenesis for the development of the typhoid point-of-care diagnostics, medications, and vaccines.
