Objectives: To profile the presentation and management of patients seen at a velopharyngeal insufficiency (VPI) clinic and to explore the role of commonly used investigations in the workup of VPI.

Design: Retrospective review.

Setting: Tertiary care VPI clinic.

Methods: A computerized database created at the time of patient assessment was accessed to review 75 patients seen over an 18-month span.

Main Outcome Measures: Descriptive analysis of patient demographics, presenting complaints, pathophysiology, and treatment. The incidence of chromosome 22q microdeletion in patients presenting to such a clinic was also determined.

Results: The most common etiology was persistent VPI following prior cleft palate surgery. Eleven percent of presenting patients were identified with 22q microdeletion by fluorescent in situ hybridization testing.

Conclusions: VPI is the result of a wide number of etiologies, with a high incidence of 22q microdeletion identified. Routine genetic testing in VPI clinics is advocated.

Objective: One in every 4 individuals born with a 22q11.2 microdeletion will develop schizophrenia. Thirty years of clinical genetic testing capability have enabled detection of this major molecular susceptibility for psychotic illness.

Article Synopsis
  • The study investigated the prevalence of obesity and metabolic syndrome (MetS) in 103 adults with a specific genetic condition (microdeletion 22q11.2), finding significantly higher rates of both compared to the general population.* -
  • Among the participants, 32% had generalized obesity, 51.5% had abdominal obesity, and 33% had MetS, with these numbers contrasting sharply with population-based statistics.* -
  • Age was identified as a key factor influencing obesity and MetS outcomes, with older age correlating positively with higher BMI and waist circumference, particularly in individuals not using antipsychotic medications.*

Objective: To determine the distribution of major fetal congenital heart diseases (CHDs) diagnosed antenatally during routine second-trimester obstetric anatomical scans in an unselected population at a single tertiary centre and to characterise and stratify risk factors, genetic diagnosis and long-term health at 4 years old.

Method: A single-centre cohort study of all major fetal CHDs detected on routine obstetric fetal anatomical ultrasound scans between January 2014 and December 2017 was performed in an unselected population. Demographic details, fetal echocardiogram reports, genetic test results, delivery outcomes and postnatal progress were stratified by CHD subtype.

22q11 Deletion Syndrome (22q11DS) is the most common microdeletion syndrome with broad phenotypic variability, leading to significant morbidity and some mortality. The varied health problems associated with 22q11DS and the evolving phenotype (both medical and developmental/behavioural) across the lifespan can strongly impact the mental health of patients as well as their caregivers. Like caregivers of children with other chronic diseases, caregivers of children with 22q11DS may experience an increased risk of traumatisation and mental health symptoms.
