A Toolbox of Surgical Techniques for Palatal Fistula Repair.

OBJECTIVE: To provide an inventory of oronasal fistula repair techniques alongside expert commentary on which techniques are appropriate for each fistula type. DESIGN: A 4-stage approach was used to develop a consensus on surgical techniques available for fistula repair: (1) in-person discussion of oronasal fistula cases among cleft surgeons, (2) development of a schema for fistula management using transcripts of the in-person case discussion, (3) evaluation of the preliminary schema via a web-based survey of additional cleft surgeons, and (4) revision of the management schema using survey responses. PARTICIPANTS: Six cleft surgeons participated in the in-person case discussion. Eleven additional surgeons participated in the web-based survey. Participants had diverse training experiences, having completed residency and fellowship at 20 different hospitals. RESULTS: A schema for fistula management was developed, organized by fistula location. The schema catalogues all viable approaches for each location. For fistulae involving the soft palate, the schema stresses the importance of evaluating for velopharyngeal insufficiency (VPI) and incorporating VPI management into fistula repair. For fistulae involving the hard palate, the schema separately enumerates the techniques available for nasal lining repair and for oral lining repair in each region. The schema also catalogues the diversity of approaches to lingual- and labioalveolar fistula, including variation in timing, orthodontic preparation, and simultaneous alveolar bone grafting. CONCLUSIONS: This study employed consensus methods to create a comprehensive inventory of available fistula repair techniques and to identify preferential techniques among a diverse group of surgeons.

Marked Variation Exists Among Surgeons and Hospitals in the Use of Secondary Cleft Lip Surgery.

OBJECTIVE: To identify child-, surgeon-, and hospital-specific factors at the time of primary cleft lip repair that are associated with the use of secondary cleft lip surgery. DESIGN: Retrospective cohort study. SETTING: Forty-nine pediatric hospitals. PARTICIPANTS: Children who underwent cleft lip repair between 1999 and 2015. MAIN OUTCOME MEASURE: Time from primary cleft lip repair to secondary lip surgery. RESULTS: By 5 years after primary lip repair, 24.0% of children had undergone a secondary lip surgery. In multivariable analysis, primary lip repair before 3 months had a 1.22-fold increased hazard of secondary surgery (95% confidence interval [CI]: 1.02-1.46) compared to repair at 7 to 12 months of age, and children with multiple congenital anomalies had a 0.77-fold decreased hazard of secondary surgery (95% CI: 0.68-0.87). After adjusting for cleft type, age at repair, presence of multiple congenital anomalies, and procedure volume, there remained substantial variation in secondary surgery use among surgeons and hospitals (P < .01). For children with unilateral cleft lip repaired at 3 to 6 months of age, the predicted proportion of children undergoing secondary surgery within 5 years of primary repair ranged from 4.9% to 21.8% across surgeons and from 4.5% to 24.7% across hospitals. CONCLUSIONS: There are substantial differences among surgeons and hospitals in the rates of secondary lip surgery. Further work is needed to identify causes for this variation among providers.

Omeprazole-clopidogrel interaction and neurovascular complications after flow-diverter device placement.

BACKGROUND: Omeprazole is a common proton pump inhibitor that interferes with the hepatic activation of clopidogrel and potentially reduces its platelet-inhibitory effect. Omeprazole has been shown to increase P2Y12 levels and adverse cardiovascular outcomes in patients treated with drug-eluting stents. However, omeprazole use among patients treated with flow-diverting stents for intracranial aneurysms has not been evaluated. METHODS: All patients with placement of a flow-diverting device for treatment of an intracranial aneurysm at a tertiary institution from January 1, 2014, to December 31, 2018, were retrospectively analyzed. Inclusion criteria included documented clopidogrel administration, available P2Y12 levels, and thorough documentation of administration of other medications, including omeprazole. RESULTS: A total of 138 patients met the inclusion criteria. Sixteen patients (12%) were receiving omeprazole and clopidogrel at treatment. P2Y12 reactivity was significantly greater in the omeprazole cohort (mean P2Y12 level, 250 P2Y12 reaction units (PRU)) than in the control cohort (mean P2Y12 level, 112PRU) (P<0.001). Furthermore, a greater proportion of patients had a P2Y12 level >180 PRU in the omeprazole cohort (14 of 16 [88%] vs 24 of 122 [20%]; P<0.001; OR [95% CI], 29 [6-134]). CONCLUSION: Omeprazole was associated with a significant increase in the mean P2Y12 reactivity level among patients with intracranial aneurysms treated with flow-diverting devices who received clopidogrel. However, receipt of omeprazole was not associated with an increased risk of ischemic events or stent stenosis. For neuroendovascular patients who are treated with a flow diverter while receiving clopidogrel, alternative gastrointestinal medication regimens should be considered.

Anti-NMDA receptor encephalitis and brain atrophy in children and adults: A quantitative study.

PURPOSE: To determine whether brain atrophy was present in patients with anti-N-methyl-d-aspartate receptor encephalitis (anti-NMDARE) using qualitative and quantitative analyses of brain magnetic resonance imaging (MRI) and to explore clinical differences in patients with anti-NMDARE with or without brain atrophy. METHODS: A retrospective observational study encompassing the serologic, cerebrospinal fluid, and brain MRI data of 23 patients with anti-NMDARE was conducted. Median patient age was 14 years (interquartile range [IQR], 12 years). The cohort included 15 children (<18 years old) and 8 adults (≥18 years old). There were 6 male and 17 female patients. Imaging analysis involved 2 expert readers' observations of MRIs and automated volumetric quantification using NeuroQuant (CorTechs Labs, Inc.) software. RESULTS: Of 23 pediatric and adult patients, 11 patients had 14 brain MRIs that were quantitatively analyzed. Quantitative NeuroQuant volumetric analysis showed atrophy in 9 of 14 MRIs for 7 of 11 patients compared to age-controlled normative data. In these 9 MRIs, atrophy was present in the temporal lobes (n = 9), cerebral cortex (n = 3), and cerebellum (n = 3). Qualitative analysis of 59 MRIs (23 patients) revealed volume loss in 6 patients: 5 with global cerebral and temporal lobe volume loss and 1 with temporal lobe volume loss. No patient showed cerebellar volume loss on qualitative analysis. Mean length of stay in the intensive care unit was not significantly different for patients with or without quantitative volume loss (3.5 [5.2] vs 27.4 [23.4] days; p = 0.08). CONCLUSIONS: In this cohort of patients with anti-NMDARE, quantitative volumetric analysis showed brain atrophy, particularly affecting the temporal lobes, in 64% (7/11) of the patients. Qualitative analysis showed brain atrophy in 26% (6/23). These findings highlight the increased sensitivity of quantitative methods for volume loss detection. Larger studies are needed.

Composite Anterolateral Thigh and Fascia Lata Free Flap for Abdominal and Groin Reconstruction in a Pediatric Patient.

Large abdominal wall and groin defects present complex reconstructive challenges. These defects typically require free flap reconstruction to bring in healthy vascularized tissue and recreate the complex full-thickness defect. A 6-year-old previously healthy girl presented to our trauma center after sustaining a close-range shotgun injury resulting in a full-thickness defect to the inferior hemi-abdomen and groin. A composite anterolateral thigh flap with fascia lata free flap was performed to reconstruct the myofascial, skin, and subcutaneous tissue of the abdomen and groin. We present the first composite anterolateral thigh flap with fascia lata for full-thickness abdominal wall and groin reconstruction in a pediatric patient.

Complications of Microvascular Upper Lip and Free Grafted Nasal and Eyebrow Replantation After Assault via Human Bite.

Amputation of facial soft tissue, particularly avulsion due to human bite, is an uncommon injury that has severe cosmetic and functional implications. Microsurgical replantation has the potential for superior aesthetic outcomes and restoration of function. We report a case of a 46--year-old male who sustained avulsion injuries from human bites, which included portions of his eyebrow, nose, and upper lip. Artery and vein microvascular replantation was performed on the upper lip. The amputated eyebrow and nasal segments were replanted in a similar fashion to a skin graft. On post-operation day 1, our patient suffered an ischemic stroke followed by a myocardial infarction requiring systemic tissue plasminogen activator (tPA) treatment. Following administration of tPA, there was continuous bloody discharge from the replant sites and the eyebrow, nose, and upper lip began to appear increasingly dusky. Our patient was determined to be a high-risk candidate for immediate revision surgery and he subsequently underwent a six-stage secondary reconstruction. At his most recent four-month follow-up, our patient is satisfied with his cosmetic and functional outcomes. This was a case of failed microvascular upper lip replantation and eyebrow and nasal replacement complicated by stroke and myocardial infarction. The authors review the common complications in replantation, particularly pertaining to upper lip reanastamosis, and discuss a potential novel complication encountered in this case relevant to both free graft and microvascular replantation.
