UNASSIGNED: Persistent tympanic membrane perforation is a known complication of pressure-equalizing (PE) tube insertion. Conductive hearing loss and otorrhea can necessitate surgical repair of these perforations. Long-term tympanostomy tube placement can increase the risk of these complications. Patients with velocardiofacial syndrome (VCFS) typically require prolonged PE tube placement and are thought to have higher risk of requiring additional otologic interventions after PE tube placement. To date, no work has established rates of post-PE tube complications requiring myringoplasty or tympanoplasty in patients with VCFS.
UNASSIGNED: A retrospective case review including all patients with VCFS at a single large children\'s hospital between the years 2000 and 2020 was performed. Number of PE tube insertions required and additional otologic interventions performed were the primary endpoints assessed.
UNASSIGNED: Of 212 total patients with VCFS, 66 (31%) underwent PE tube placement. Of these children, 46 (70%) required 2 or more sets of PE tubes. A total of 53 patients (80.3%) required no otologic interventions apart from PE tube insertions. Of the 13 patients (19.7%) requiring additional otologic surgery, 6 (9.5%) underwent myringoplasty, and 9 patients (13.6%) required tympanoplasty. There was no significant difference in tympanoplasty (P > 1), myringoplasty (P > 1), or other surgical intervention rates (P = .7464) between VCFS patients with any type of cleft palate versus those with anatomically normal palates.
UNASSIGNED: This work suggests that most VCFS patients that require tubes, require at least 2 sets of PE tubes, and that the rate of post-PE tube complications requiring further otologic surgery is an order of magnitude higher than the rate established at this institution. Counseling for PE tube placement in VCFS patients may require specific dialogue regarding the substantially increased risk of complications and effort to build appropriate expectations for surgical outcomes regardless of palatal status.

BACKGROUND: Research on the multi-faceted characteristics of persistent severe acute lower back pain (LBP) resulting from acute vertebral compression fractures (VCFs) is lacking.
OBJECTIVE: To investigate the psychological and functional status of older patients with persistent severe acute LBP after conservative treatment of VCFs.
METHODS: This prospective study included women aged 50 years and older who had acute VCFs and were admitted to the hospital. Pain intensity, depression, pain catastrophizing, activities of daily living (ADL), muscle strength, and vertebral deformity were assessed on admission. At 2 and 4 weeks post-admission, physical performance tests were performed along with the above measures.
RESULTS: We divided 131 participants into severe (n= 64) and mild (n= 67) groups according to their pain intensity at 4 weeks. Compared to the mild group, the severe group showed significantly higher levels of depression and catastrophizing, with significantly poorer muscle strength and endurance. There were no significant differences in ADL and vertebral deformities between the two groups.
CONCLUSIONS: Our results suggest that older patients with persistent severe acute LBP resulting from VCFs tend to be depressed and pain catastrophizing. Furthermore, persistent severe acute LBP negatively impacts endurance and muscle strength but not ADL.

Inversion polymorphisms between low-copy repeats (LCRs) might predispose chromosomes to meiotic non-allelic homologous recombination (NAHR) events and thus lead to genomic disorders. However, for the 22q11.2 deletion syndrome (22q11.2DS), the most common genomic disorder, no such inversions have been uncovered as of yet. Using fiber-FISH, we demonstrate that parents transmitting the de novo 3 Mb LCR22A-D 22q11.2 deletion, the reciprocal duplication, and the smaller 1.5 Mb LCR22A-B 22q11.2 deletion carry inversions of LCR22B-D or LCR22C-D. Hence, the inversions predispose chromosome 22q11.2 to meiotic rearrangements and increase the individual risk for transmitting rearrangements. Interestingly, the inversions are nested or flanking rather than coinciding with the deletion or duplication sizes. This finding raises the possibility that inversions are a prerequisite not only for 22q11.2 rearrangements but also for all NAHR-mediated genomic disorders.

Previous studies have repeatedly found altered temporal characteristics of EEG microstates in schizophrenia. The aim of the present study was to investigate whether adolescents affected by the 22q11.2 deletion syndrome (22q11DS), known to have a 30 fold increased risk to develop schizophrenia, already show deviant EEG microstates. If this is the case, temporal alterations of EEG microstates in 22q11DS individuals could be considered as potential biomarkers for schizophrenia. We used high-density (204 channel) EEG to explore between-group microstate differences in 30 adolescents with 22q11DS and 28 age-matched controls. We found an increased presence of one microstate class (class C) in the 22q11DS adolescents with respect to controls that was associated with positive prodromal symptoms (hallucinations). A previous across-age study showed that the class C microstate was more present during adolescence and a combined EEG-fMRI study associated the class C microstate with the salience resting state network, a network known to be dysfunctional in schizophrenia. Therefore, the increased class C microstates could be indexing the increased risk of 22q11DS individuals to develop schizophrenia if confirmed by our ongoing longitudinal study comparing both the adult 22q11DS individuals with and without schizophrenia, as well as schizophrenic individuals with and without 22q11DS.

Individuals with 22q11.2 deletion syndrome (22q11.2DS) are impaired at exploring visual information in space; however, not much is known about visual form discrimination in the syndrome. Thirty-five individuals with 22q11.2DS and 41 controls completed a form discrimination task with global forms made up of local elements. Affected individuals demonstrated clear impairment in detecting local, but not global, differences. Nevertheless, 22q11.2DS participants easily discriminated the same local elements when they were displayed in isolation, and further use of a prime demonstrated preserved facilitation of local processing in 22q11.2DS. These results did not differ by age or IQ. This study illustrates the impact of visuospatial impairments on form discrimination, and suggests how these difficulties may affect visual scanning in 22q11.2DS.

We present prenatal diagnosis of de novo 22q11.2 microdeletion syndrome using uncultured amniocytes in a pregnancy with conotruncal heart malformations in the fetus. We discuss the genotype-phenotype correlation and the consequence of haploinsufficiency of TBX1, COMT, UFD1L, GNB1L and MED15 in the deleted region. We review the literature of chromosomal loci and genes responsible for conotruncal heart malformations and tetralogy of Fallot.

We present prenatal diagnosis of mosaicism for a small supernumerary marker chromosome (sSMC) derived from chromosome 22 associated with cat eye syndrome (CES) using cultured amniocytes in a pregnancy with fetal microcephaly, intrauterine growth restriction, left renal hypoplasia, total anomalous pulmonary venous return with dominant right heart and right ear deformity. The sSMC was bisatellited and dicentric, and was characterized by multiplex ligation-dependent probe amplification (MLPA) and array comparative genomic hybridization (aCGH). The SALSA MLPA P250-B1 DiGeorge Probemix showed duplication of gene dosage in the CES region. aCGH showed a 1.26-Mb duplication at 22q11.1-q11.21 encompassing CECR1-CECR7. The sSMC was likely inv dup(22) (q11.21). Prenatal diagnosis of an sSMC(22) at amniocentesis should alert CES. MLPA, aCGH and fetal ultrasound are useful for rapid diagnosis of CES in case of prenatally detected sSMC(22).
