RESUMO

A 60-year-old woman with a ∼450 cm 2 right cervicofacial defect following successful treatment of necrotizing fasciitis was consulted for reconstruction. She had complete orbital, malar, buccal, labial, submental, and anterolateral neck skin and soft tissue defects and near complete defects of the forehead and nasal sidewall. She underwent reconstruction with a large 24 cm×11 cm supraclavicular, deltopectoral, forehead rotational, and labial advancement flaps with skin grafting of the orbit. Follow-up at 2 months demonstrated complete take of all flaps. The patient was satisfied with her appearance and considered her outcome favorable. She exhibited comparably premorbid speech and oral competence. Large defects of the head and neck require thorough surgical planning and consideration of a subunit reconstruction technique. While free tissue transfer provides a large area of healthy tissue from a suitable donor site, subunit reconstruction with local and regional flaps can provide a superior outcome in the correct patient.

RESUMO

OBJECTIVE: To identify differences in inbox and secure message burden among otolaryngologists based on demographics and subspecialty over 4 years. METHODS: Inbox data were queried from January 2019 until December 2022. Otolaryngologists were categorized into cohorts by area of practice and gender. All inbox tasks, secure messages, and clinical encounters were collected and compared by gender, practice type, and years in practice. Means were compared using t-tests and chi-squared tests. RESULTS: Of the 128 physicians, 45.7% were comprehensive otolaryngologists and 61.3% were male. The most common subspecialties were facial plastics (15.6%), oncology (8.6%), and otology (7.8%). Otolaryngologists had an average of 143.5 inbox tasks per month, with 97.2 (67.7%) of them being secure messages, resulting in an average of 1.14 inbox tasks and 0.80 secure messages per clinical encounter. The ratio of secure messages per clinical encounter was consistent across all specialties except oncology (1.10, P = .003). Otology (0.86, P = .032) and facial plastics (0.95, P = .028) had significantly lower ratios of inbox tasks to clinical encounters when compared to their colleagues, while oncology had a higher ratio (1.70, P < .001). No significant differences in inbox burden were observed between genders, years in practice, or languages spoken. Secure messages steadily increased over the study period. CONCLUSION: Inbox burden for otolaryngologists primarily stems from patient secure messages and varies across subspecialties. Considerations should be made to the inbox burden of head and neck oncologists. The implementation of support systems for inbox management could improve the imbalance between clinical and non-clinical responsibilities in otolaryngology. LEVEL OF EVIDENCE: Level III, Retrospective Cohort Study.

RESUMO

OBJECTIVES: The objectives of this study are to (i) estimate the incidence of vestibular schwannoma (VS) among patients in an integrated healthcare system who present for evaluation of sudden sensorineural hearing loss (SSNHL) and (ii) evaluate the efficacy of empiric steroid therapy on audiologic recovery among SSNHL patients ultimately diagnosed with VS. METHODS: A retrospective chart review was performed on patients presenting with SSNHL in 2021 at a multicenter integrated healthcare system serving over 4 million members. Patient demographics, audiometric data, VS diagnosis, therapeutic steroid intervention, and data regarding treatment response were recorded. A clinically significant audiometric improvement was defined as (i) an increase of 15% in word recognition score, (ii) a decrease of 15 dB in four-frequency pure-tone average (PTA) using frequencies of 500, 1000, 2000, and 4000 Hz, or (iii) a PTA of <20 dB on follow-up audiogram. RESULTS: Six hundred fifty-eight patients were reviewed, of which 309 (56.0% male; mean, 57.5 years) met the inclusion criteria with audiometric data and magnetic resonance imaging data. Ten patients (70.0% male; mean, 51.3 years) were found to have VS. Of these, five patients received oral steroid therapy alone, and five had combination therapy (oral + intratympanic steroid injections). No patients received intratympanic steroid therapy alone. Median PTA improvement with steroid therapy was 3.1-dB hearing loss, and median word recognition score improvement was 16.5%. Six of 10 patients demonstrated clinically significant audiometric improvement with steroid therapy. CONCLUSION: This study represents the largest US-based study showcasing the prevalence of VS in patients originally presenting with SSNHL. It also reinforces previous findings that VS does not preclude trials of steroid therapy.

RESUMO

OBJECTIVE: Nasal bone fractures are the most common facial bone fractures. However, there is limited literature on the etiology of these fractures, particularly distribution across sports and other recreational activities. METHODS: The Nationwide Electronic Injury Surveillance System (NEISS) national injury database was queried for emergency department visits involving the diagnosis of nasal or nose fractures associated with sports and recreation activities over the most recent 10 year span available. Demographic, disposition, and weighted incidence were analyzed. RESULTS: Total incidence of nasal fractures across 10 years was 158 979. The mean age of nasal bone fractures was 20.4 years old. Nasal fractures were more common in males (74.6%) and white patients (54.1%). National estimated incidence of nasal fractures decreased from 21 028 in 2009 to 11 108 in 2018, a reduction of 47.2%. The most common causes among all patients were basketball (23.2%), baseball (17.1%), softball (9.8%), soccer (7.4%), and football (7%). In pediatric patients, the most common cause was baseball (25.1%). The majority (98.1%) of patients were discharged from the emergency department, while 0.9% of patients were admitted. CONCLUSION: The most common recreational causes of nasal fractures are sports, with the most common being non-contact sports like basketball and baseball. However, the incidence of nasal bone fractures due to recreational causes nationwide has decreased significantly over the past 10 years. This may reflect improved safety protocols among athletes.

RESUMO

Nasal septal mucoceles are a rare occurance, and reports in the current literature are limited. We describe the case of a 73-year-old woman who developed a nasal septal mucocele several days after an episode of angioedema. The lesion was treated with 2 rounds of needle aspiration with antibiotics and the application of silastic splints. There was no recurrence after 1 month, though the patient developed a saddle nose deformity. She ultimately underwent reconstruction with a diced-cartilage dorsal augmentation graft with fibrin glue. We review the learning points of this case and summarize existing literature on this disease.

RESUMO

Epidemiological evidence indicates that cadmium and arsenic exposure increase lung cancer risk. Cadmium and arsenic are environmental contaminants that act as endocrine disruptors (EDs) by activating estrogen receptors (ERs) in breast and other cancer cell lines but their activity as EDs in lung cancer is untested. Here, we examined the effect of cadmium chloride (CdCl2) and sodium arsenite (NaAsO2) on the proliferation of human lung adenocarcinoma cell lines. Results demonstrated that both CdCl2 and NaAsO2 stimulated cell proliferation at environmentally relevant nM concentrations in a similar manner to 17ß-estradiol (E2) in H1793, H2073, and H1944 cells but not in H1792 or H1299 cells. Further studies in H1793 cells showed that 100 nM CdCl2 and NaAsO2 rapidly stimulated mitogen-activated protein kinase (MAPK, extracellular-signal-regulated kinases) phosphorylation with a peak detected at 15 min. Inhibitor studies suggest that rapid MAPK phosphorylation by NaAsO2, CdCl2, and E2 involves ER, Src, epidermal growth factor receptor, and G-protein coupled ER (GPER) in a pertussis toxin-sensitive pathway. CdCl2 and E2 activation of MAPK may also involve ERß. This study supports the involvement of membrane ER and GPER signaling in mediating cellular responses to environmentally relevant nM concentrations of CdCl2 and NaAsO2 in lung adenocarcinoma cells.
