Objective: The primary goal of this study was to determine in patients with normohormonal primary hyperparathyroidism (NHHPT) what percent reduction in post‐excision intraoperative parathyroid hormone (IOPTH) from baseline would yield a rate of cure comparable to that in patients with classical primary hyperparathyroidism (PHPT). Methods: This is a retrospective cohort study of patients who underwent parathyroidectomy between July 2013 and February 2020. Demographic data, preoperative, intraoperative, and postoperative metrics were collected. Patients with NHHPT were compared to those with classical PHPT. Subgroup analyses were performed. Results: Of the 496 patients included in the study, 66 (13.3%) were of the normohormonal variant based on preoperative intact parathyroid hormone (PTH) levels and 28 (5.6%) based on baseline IOPTH levels. The cure rates in the two normohormonal groups were not significantly different from their classical counterparts (98.4% and 100.0% vs. 97.1%, p = 1.000). The median percent decline in post‐excision IOPTH from baseline that achieved cure in the normohormonal groups were 82.6% and 80.4% compared to their respective controls at 87.3%, p = 0.011 and p = 0.001. Although the rate of multiglandular disease was higher in one of the normohormonal variant groups, this difference was due to a higher rate of double adenomas, not four‐gland hyperplasia. Conclusion: Patients with NHHPT undergoing parathyroidectomy can expect cure rates similar to that in patients with classical PHPT. The results of this study indicate that achieving an 80% drop or more in IOPTH levels predicts a high likelihood of cure. This is true irrespective of whether the patient is deemed normohormonal based on preoperative or intraoperative testing.

Objectives: Unilateral clear thin rhinorrhea (UCTR) can be concerning for a nasal cerebrospinal fluid (CSF) leak. Beta‐2 transferrin electrophoresis has been the gold standard for initial non‐invasive confirmatory testing for CSF rhinorrhea, but there can be issues with fluid collection and testing errors. Ipratropium bromide nasal spray (IBNS) is highly effective at reducing rhinitis‐related rhinorrhea, and should presumably not resolve CSF rhinorrhea. This study assessed whether different clinical features and IBNS response helped predict presence or absence of CSF rhinorrhea. Methods: A prospective cohort study was conducted where all patients with UCTR had nasal fluid tested for beta‐2 transferrin, and were prescribed 0.06% IBNS. Patients were diagnosed with CSF rhinorrhea or other rhinologic conditions. Clinical variables like IBNS response (rhinorrhea reduction), positional worsening, salty taste, postoperative state, female gender, and body‐mass index were assessed for their ability to predict CSF rhinorrhea. Sensitivity, specificity, and predictive values and odds ratios were calculated for all clinical variables. Results: Twenty patients had CSF rhinorrhea, and 53 had non‐CSF etiologies. Amongst clinical variables assessed for predicting CSF absence or presence, significant associations were shown for IBNS response (OR = 844.66, p = 0.001), positional rhinorrhea worsening (OR = 8.22, p = 0.049), and body‐mass index ≥30 (OR = 2.92, p = 0.048). IBNS response demonstrated 96% sensitivity and 100% specificity, and 100% positive and 91% negative predictive values for predicting CSF rhinorrhea. Conclusions: In patients with UCTR, 0.06% IBNS response is an excellent screening tool for excluding CSF rhinorrhea, and should be considered in the diagnostic workup of CSF rhinorrhea.

Objectives: Investigate the use of nasal endoscopy, sinus imaging, and neurologic evaluation in patients presenting to a rhinologist primarily for craniofacial pain. Methods: This was a retrospective analysis of consecutive outpatients presenting to a rhinologist between 2016 and 2019 with chief complaints of craniofacial pain with or without other sinonasal symptoms, who were then referred to and evaluated by headache specialists. Data analyzed included sinusitis symptoms, Sino-Nasal Outcome Test (SNOT-22) scores (and facial pain subscores), pain location, nasal endoscopy, computed tomography (CT) findings, and headache diagnoses made by headache specialists. Results: Of the 134 patients with prominent craniofacial pain, the majority of patients were diagnosed with migraine (50%) or tension-type (22%) headache, followed by multiple other non-sinogenic headache disorders. Approximately 5% of patients had headaches attributed to sinusitis. Amongst all patients, 90% had negative nasal endoscopies. Patients with negative endoscopies were significantly less likely to report smell loss (P =.003) compared to those with positive endoscopies. Poor agreement was demonstrated between self-reported pain locations and sinus findings on CT (kappa values < 0.20). Negative nasal endoscopy showed high concurrence with negative CT findings (80%-97%). Conclusions: Patients presenting with chief complaints of craniofacial pain generally met criteria for various non-sinogenic headache disorders. Nasal endoscopy was negative in 90% of patients, and CT demonstrated poor agreement with pain locations. Nasal endoscopy and CT shared high concurrence rates for negative sinus findings. The value of nasal endoscopy over sinus imaging in craniofacial pain evaluation should be explored in future studies. [ABSTRACT FROM AUTHOR]

The aim of this research was to examine predictors and characterize causes of suicide death in people with traumatic brain injury (TBI) and conduct sensitivity analyses with and without people whose first diagnosis of TBI occurred within 3 days of their suicide death. This case-control study examined suicide risk for people with TBI in eight Mental Health Research Network–affiliated healthcare systems. Sample 1 included 61 persons with TBI who died by suicide and their 75 matched controls with TBI who did not die by suicide between January 1, 2000, and December 31, 2013. Sample 2 excluded the 34 persons with TBI whose first TBI diagnosis occurred within 3 days of their suicide death and their 46 matched controls. Descriptive statistics characterized the sample stratified by cases and controls, while conditional logistic regression models estimated the adjusted odds of suicide. Over half of suicide deaths occurred within 3 days of a person's first diagnosis of TBI in the larger sample. After excluding these persons, people with TBI were 2.84 (95% confidence interval [CI]: 2.15–2.73) times more likely to die by suicide than were people without TBI. Among those with TBI, men were 16.39 times (95% CI: 1.89–142.15) more likely to die by suicide than were women. Accounting for TBI as a potential consequence of suicide attenuates the association between TBI and suicide, but a robust association persists—especially among men. Ultimately, all people with TBI should be carefully screened and monitored for suicide risk. People with traumatic brain injury (TBI) were at considerably elevated risk for suicide death Men with TBI had significantly increased risk of suicide death compared to women with TBI TBI timing suggests confusion of risk factors for and consequences of suicide [ABSTRACT FROM AUTHOR]

Objective: Odontogenic sinusitis (ODS) can cause infectious orbital, intracranial, and osseous complications. Diagnosis and management of complicated ODS have not been discussed in recent sinusitis guidelines. The purpose of this systematic review was to describe epidemiological and clinical features, as well as management strategies of complicated ODS. Data Sources: PubMed, EMBASE, and Cochrane Library. Review Methods: A systematic review was performed to describe various features of complicated ODS. All complicated ODS studies were included in qualitative analysis, but studies were only included in quantitative analysis if they reported specific patient-level data. Results: Of 1126 studies identified, 75 studies with 110 complicated ODS cases were included in qualitative analysis, and 47 studies with 62 orbital and intracranial complications were included in quantitative analyses. About 70% of complicated ODS cases were orbital complications. Only 23% of complicated ODS studies were published in otolaryngology journals. Regarding ODS-related orbital and intracranial complications, about 80% occurred in adults, and 75% were male. Complicated ODS occurred most commonly from apical periodontitis of maxillary molars. There were no relationships between sinusitis extent and orbital or intracranial complications. High rates of anaerobic and α-hemolytic streptococcal bacteria were identified in complicated ODS. Management generally included systemic antibiotics covering aerobic and anaerobic bacteria, and surgical interventions were generally performed to address both the complications (orbital and/or intracranial) and possible infectious sources (dentition and sinuses). Conclusion: ODS should be considered in all patients with infectious extrasinus complications. Multidisciplinary management between otolaryngologists, dental specialists, ophthalmologists, and neurosurgeons should be considered to optimize outcomes. [ABSTRACT FROM AUTHOR]
