Granulomatous Inflammation of the Skull Base: A Rare Case of Mycobacterium tuberculosis in the United States.

The differential for an ill-defined, bone-destructive, granulomatous lesion of the skull base includes malignancy, as well as autoimmune and infectious processes. Suspicion for tuberculosis of the skull base in high-risk patients is particularly necessary given the difficulty to culture on standard cultures, need for specific and prolonged antibiotic therapy, and dire morbidity if not diagnosed and treated in a timely manner. Repeat biopsies and cultures were necessary to diagnose this case of Mycobacterium tuberculosis of the skull base after initial biopsy was non-diagnostic. Laryngoscope, 2024.

Laryngeal Hyposensitivity in Obstructive Sleep Apnea.

INTRODUCTION: Impaired laryngopharyngeal sensation has been implicated in obstructive sleep apnea (OSA) and may play an important pathophysiological role. We evaluated sensory function in OSA by examining the laryngeal adductor reflex (LAR) response rate and temporal profile to tactile stimulation. METHODS: Laryngeal sensation testing was performed in awake adults with and without diagnosed OSA by stimulating the medial aryepiglottic fold or arytenoid using 30-mm 5-0 and 4-0 nylon Cheung-Bearelly monofilaments. Video analysis by two independent reviewers evaluated for the presence of the LAR in response to satisfactory stimuli and LAR latency to vocal fold adduction. RESULTS: Twenty-six OSA and 12 control subjects were tested with 270 satisfactory stimuli. The mean full LAR response rate to 4-0 stimulation was 38.3% in OSA vs 86.9% in control subjects (p <0.001) and to 5-0 stimulation was 27% in OSA vs 63.9% in control subjects (p <0.001). The mean LAR latency to vocal fold closure in OSA was 123.7 ms (SD 35.8) vs 156.4 ms (SD 44.3) in control (p = 0.04) subjects. OSA LAR latency was positively correlated with the apnea-hypopnea index (r = 0.30; p = 0.008). CONCLUSION: The OSA group exhibited reduced LAR response rates and shortened LAR latency, where latency was correlated with disease severity. Laryngeal hyposensitivity was affirmed and changes to LAR sensorimotor temporal dynamics were revealed. These pathophysiological alterations to the LAR may be accounted for by decreased somatosensory receptor sensitivity, increased sympathetic tone, and reorganized brain stem function in OSA.

The Effect of an Oxytocin Decision Support Checklist on Oxytocin Use and Maternal and Neonatal Outcomes: A Retrospective Cohort Study.

OBJECTIVE: To assess the association between use of an oxytocin decision support checklist with oxytocin usage and clinical outcomes. STUDY DESIGN: We conducted a retrospective cohort study of patients with singleton gestations at 370/7 weeks or greater who received oxytocin during labor from October 2012 to February 2017 at an integrated community health care system during three exposure periods: (1) pre-checklist; (2) after paper checklist implementation; and (3) after checklist integration into the electronic medical record (EMR). The checklist was a clinical decision support tool to standardize the dosing and management of oxytocin. Thus, our primary outcomes included oxytocin infusion rates and cumulative dose. Secondary outcomes included maternal and neonatal outcomes. We controlled for maternal risk factors with multivariable regression analysis and stratified by mode of delivery. RESULTS: A total of 34,269 deliveries were included. Unadjusted analyses showed that compared with pre-checklist, deliveries during the paper and EMR-integrated periods had a lower cumulative dose (4,670 ± 6,174 vs. 4,318 ± 5,719 and 4,286 ± 5,579 mU, p < 0.001 for both), lower maximal infusion rate (9.9 ± 6.8 vs. 8.7 ± 5.8 and 8.4 ± 5.6 mU/min, p < 0.001 for both), and longer duration of oxytocin use (576 ± 442 vs. 609 ± 476 and 627 ± 488 minutes, p < 0.001 and p = 0.01, respectively). The unadjusted rates of cesarean, 5-minute Apgar <7, mechanical ventilation, and neonatal hospital length of stay were similar between periods. The adjusted mean difference in time from admission to delivery was longer during the EMR-integrated period compared with pre-checklist (3.0 [95% confidence interval: 2.7-3.3] hours, p < 0.001). CONCLUSION: Oxytocin checklist use was associated with decreased oxytocin use patterns at the expense of longer labor times. Findings were more pronounced with EMR integration. KEY POINTS: · An oxytocin decision support checklist is associated with reduced amounts of oxytocin used.. · However, checklists were associated with longer duration of oxytocin use and of labor.. · Results were more pronounced in the EMR-integrated checklist compared with paper checklist..

Digital Storytelling as a Tool to Increase Colorectal Cancer Screening Intention in a Latinx Church Community.

Although colorectal cancer screening (CRCS) rates have improved for all racial groups due to wider availability of screening, Latinx continue to have lower screening rates and are more likely to be diagnosed with later stages of colorectal cancer compared to non-Latinx whites. More culturally tailored educational interventions are needed to reach this population. This study introduced a digital storytelling (DST) intervention in a church community setting and explored its potential to influence CRCS intention and perception among Latinx and the acceptability of the DST intervention. Participants (n=20) between the ages of 50 and 75 who were not up-to-date with CRCS were recruited to view digital stories developed by fellow church members with previous CRCS experience. They completed surveys assessing their intention to complete CRCS before and after the viewing and were asked to participate in focus groups to understand, qualitatively, how the digital stories influenced their perceptions and intentions related to CRCS. Analysis of participant narratives revealed three overarching themes related to their perceptions and intentions of CRCS after the DST intervention: (1) the duality of the faith-health connection and fatalism, (2) willingness to consider other screening methods, and (3) the push-pull of individual barriers and interpersonal facilitators. Participants felt the DST intervention humanized the CRCS process and that it would be acceptable and well received in other church settings. The introduction of a community-based DST intervention within a church setting is a novel strategy with the potential to influence members of the Latinx church population to complete CRCS.

Fetal heart rate patterns and the incidence of adverse events after oral misoprostol administration for cervical ripening among low-risk pregnancies.

OBJECTIVE: Though misoprostol is commonly used for inpatient cervical ripening, its use in outpatient settings has been limited by safety concerns. This study was conducted to assess the association between early fetal heart tracing (FHT) and maternal tocodynamometry patterns and the incidence of adverse fetal and pregnancy outcomes after the administration of oral misoprostol for cervical ripening. METHODS: We conducted a retrospective cohort study of 9908 low-risk patients at ≥37 weeks gestation who received oral misoprostol for cervical ripening prior to rupture of membranes between 01/01/2012 and 12/31/2017 at Kaiser Permanente Northern California hospitals as inpatients. We excluded patients who received a different agent for cervical ripening or had any need for additional inpatient monitoring, including hypertensive disorders of pregnancy, diabetes, or intrauterine growth restriction. Abnormal FHT, abnormal uterine activity, and adverse pregnancy or fetal-related events documented in the electronic health record in the four hours after administration of the first and second doses of misoprostol were assessed using descriptive statistics. RESULTS: We found that 0.9% of patients experienced tachysystole after the first dose of misoprostol (0.6% without decelerations; 0.3% with decelerations). The incidence of variable decelerations only and other FHT abnormalities (i.e. bradycardia, late or prolonged decelerations, or absent or minimal variability) in the first hour after misoprostol administration were 7.1% and 6.7% respectively, and diminished over time. The need for tocolytic use was 0.2% in the first hour and declined over time to 0.03% in the fourth hour after the first dose. Urgent cesarean delivery occurred in 0.1% of patients after receiving the first dose of misoprostol. Patients who did not experience variable, prolonged, or late decelerations in the first hour after the initial misoprostol dose were less likely to have such FHT abnormalities in the subsequent three hours compared to patients who had other FHT abnormalities (11.8% among patients with no FHT abnormalities vs. 43.7% among patients with other FHT abnormalities; p <.001). The overall trends in outcomes over time were similar after the second dose of misoprostol. CONCLUSION: The risk of short-term adverse outcomes associated with misoprostol is low among relatively low-risk patients. FHT abnormalities occurred in up to 32% of patients in the first four hours of monitoring post-misoprostol. Patients with no FHT abnormalities in the first hour after receiving misoprostol had a low risk of developing adverse outcomes and FHT abnormalities on continued monitoring, while patients with any type of deceleration in the first hour were at higher risk of adverse outcomes and FHT abnormalities. Our data may inform the development of protocols for cervical ripening that allow reduced monitoring for a subset of low-risk patients, however, more research is needed to validate findings and develop clinical protocols.

Intact speech perception after resection of dominant hemisphere primary auditory cortex for the treatment of medically refractory epilepsy: illustrative case.

BACKGROUND: In classic speech network models, the primary auditory cortex is the source of auditory input to Wernicke's area in the posterior superior temporal gyrus (pSTG). Because resection of the primary auditory cortex in the dominant hemisphere removes inputs to the pSTG, there is a risk of speech impairment. However, recent research has shown the existence of other, nonprimary auditory cortex inputs to the pSTG, potentially reducing the risk of primary auditory cortex resection in the dominant hemisphere. OBSERVATIONS: Here, the authors present a clinical case of a woman with severe medically refractory epilepsy with a lesional epileptic focus in the left (dominant) Heschl's gyrus. Analysis of neural responses to speech stimuli was consistent with primary auditory cortex localization to Heschl's gyrus. Although the primary auditory cortex was within the proposed resection margins, she underwent lesionectomy with total resection of Heschl's gyrus. Postoperatively, she had no speech deficits and her seizures were fully controlled. LESSONS: While resection of the dominant hemisphere Heschl's gyrus/primary auditory cortex warrants caution, this case illustrates the ability to resect the primary auditory cortex without speech impairment and supports recent models of multiple parallel inputs to the pSTG.

Labor Induction Outcomes with Outpatient Misoprostol for Cervical Ripening among Low-Risk Women.

OBJECTIVE: In 2012, two Kaiser Permanente Northern California (KPNC) hospitals began offering outpatient cervical ripening with oral misoprostol under a study protocol. We evaluated inpatient time from admission to delivery and adverse maternal and neonatal outcomes associated with outpatient use of misoprostol for cervical ripening among low-risk women with term pregnancies. STUDY DESIGN: We conducted a retrospective cohort study comparing three groups: women who received misoprostol (1) outpatient, under a study protocol; (2) inpatient, at the study sites; and (3) inpatient, at all KPNC hospitals. Data were obtained from between 2012 and 2017. The primary outcome was time from inpatient admission to delivery. Secondarily, we evaluated maternal and neonatal outcomes, including the duration and maximum rate of oxytocin administered, rate of cesarean delivery, incidence of chorioamnionitis and blood transfusion, Apgar scores, and neonatal intensive care unit admissions. Demographic and clinical characteristics and outcomes of the outpatient group were compared with both inpatient misoprostol groups using the appropriate statistical test. Variables included in the regression analysis were either statistically significant in the bivariate analyses or have been reported in the literature to be potential confounders: maternal age at admission, race/ethnicity, body mass index, cervical dilation at initial misoprostol, and parity. RESULTS: We analyzed data from 10,253 patients: (1) 345 outpatients, under a study protocol; (2) 1,374 inpatients, at the study sites; and (3) 9,908 inpatients, at all the Kaiser hospitals. Women in the outpatient group were more likely to be white than both inpatient groups (63.3 vs. 56.3% at study sites and 47.1% in all hospitals, p = 0.002 and <0.001, respectively); other demographics were clinically comparable. Most women undergoing labor induction were nulliparous; however, a greater proportion in the outpatient group were nulliparous compared with inpatient groups (70.8 vs. 61.8% and 64.3%, p = 0.002 and 0.01). On inpatient admission for delivery, women who received outpatient misoprostol were more likely to have a cervical dilation of ≥3 cm (39.8 vs. 12.5% at study sites and 9.7% at all KPNC hospitals, p < 0.001 for both). The outpatient group had a shorter mean time between admission and delivery (23.6 vs. 29.4 at study sites and 29.8 hours at all KPNC, p < 0.001 for both). The adjusted estimated mean difference between the outpatient and inpatient group at all the Kaiser hospitals in time from admission to delivery was -6.48 hours (p < 0.001), and the adjusted estimated mean difference in cervical dilation on admission was +1.02 cm (p < 0.001). There was no difference in cesarean delivery rates between groups. The rate of chorioamnionitis in the outpatient group was higher compared with inpatients at all hospitals (17.7 vs. 10.6%, p < 0.001), but similar when compared with the inpatients at the study sites (17.7 vs. 15.4%, p = 0.29). CONCLUSION: Outpatient use of misoprostol for cervical ripening under the study protocol was associated with reduced inpatient time from admission to delivery compared with inpatient misoprostol. Although there was a higher rate of chorioamnionitis among outpatients under the study protocol compared with inpatients at all hospitals, there was no difference when compared with inpatients at the study sites. There was no difference in rates of cesarean delivery or maternal or neonatal complications with outpatient misoprostol. KEY POINTS: · Outpatient misoprostol patients had 6.46 fewer hours from admission to delivery compared with inpatients at all hospitals.. · There was no difference in the rate of cesareans between the outpatient versus inpatient misoprostol groups.. · Other maternal and neonatal complications were low and comparable among outpatients and inpatients who received misoprostol; this study was not large enough to assess rare safety outcomes..

Prophylactic transdermal scopolamine for the reduction of postoperative length of stay after uterine aspiration at Kaiser Permanente Northern California from 2017-2018.

OBJECTIVE: To determine if transdermal scopolamine is associated with decreased postoperative nausea and vomiting and shorter length of stay in the postoperative care unit among patients undergoing uterine aspiration for abortion or early pregnancy loss. STUDY DESIGN: We conducted a retrospective cohort study at an integrated medical center that initiated a protocol to prescribe transdermal scopolamine to patients undergoing uterine aspiration under moderate sedation. We compared outcomes among patients who underwent uterine aspiration in 2017, before the institution enacted the protocol, with their counterparts in 2018, immediately after the institution instated the protocol. We reviewed patient charts for data on the postoperative length of stay, use of additional antiemetics, and a standardized clinician designated postoperative nausea and vomiting score. We analyzed outcomes by relevant demographic and clinical characteristics using chi-square or Fisher's exact tests for categorical variables and t tests for continuous variables. RESULTS: The final sample included 386 patients; 228 who did not receive scopolamine and 158 who did. The cohorts were comparable in terms of demographic and clinical characteristics. The cohort that received transdermal scopolamine had a similar mean postoperative length of stay (75.4 ± 54.1 vs 71.1 ± 50.8 minutes; p = 0.43). There were no differences in the proportions of patients who were provided additional antiemetics (26 ± 11.4 vs 17 ± 10.8; p = 0.84) or had transient vomiting and retching (3 ± 1.9 vs 3 ± 1.3; p = 0.69) between the cohorts. CONCLUSION: We found no evidence that prophylactic transdermal scopolamine reduces postoperative nausea, vomiting, or length of stay among patients undergoing uterine aspiration. IMPLICATIONS: Among patients who underwent uterine aspiration under moderate sedation, use of prophylactic transdermal scopolamine was not associated with shorter postoperative length of stay or lesser use of antiemetics. Prophylactic transdermal scopolamine is not likely to be useful for patients undergoing uterine aspiration and could be an unnecessary cost.

Variation in Vaginal Hysterectomy Rates in an Integrated Healthcare System.

STUDY OBJECTIVE: To describe trends in minimally invasive hysterectomy (MIH) and assess patient, surgical, and provider characteristics associated with differences in vaginal versus laparoscopic rates within an integrated healthcare system. DESIGN: A retrospective cohort study. SETTING: Kaiser Permanente Northern California from 2008 to 2018. PATIENTS: Patients who underwent MIH for benign conditions excluding uterine prolapse and incontinence surgeries. INTERVENTIONS: Hysterectomies. MEASUREMENTS AND MAIN RESULTS: A total of 27518 hysterectomies were performed for benign indications. Of these, the proportion of MIH increased from 29.1% (2008) to 96.7% (2018) (p <.001). The proportion of vaginal hysterectomies (VHs) of all hysterectomies did not change significantly over the study period (p = .07); however, the proportion of VH among MIH cases decreased from a high of 50.6% in 2008 to 13.2% in 2018 (p <.001). VH rates were lower in obese and morbidly obese patients (p <.001 and p = .02, respectively) and in women with uterine weights >250 g (p <.001). The differences persisted after controlling for patient demographic, clinical, and surgery characteristics. Low surgical volume was inversely associated with VH (adjusted relative risk, 7.19; 95% confidence interval, 6.62-7.81; p <.001). VH rates ranged from 11.5% to 27.8% across service areas (hospitals). Service area remained a significant predictor of VH after controlling for patient (including body mass index and uterine weight) and surgery-related characteristics. Postoperative hospital stay decreased from 33.8 ± 16.4 hours (2008) to 6.1 ± 12.2 (2018) for VH. Operative time was shorter for VH than laparoscopic hysterectomies (LHs) (1.7 vs 2.5 hours; p <.001). Overall operative/perioperative complications were low and not significantly different (VH vs LH). CONCLUSION: As the proportion of MIH increased, LH became the preferred route despite similar rates of postoperative stay and intraoperative complications and shorter operative time for VH compared with LH. Service area and provider volume were independent predictors of MIH route, suggesting that training and evidence-based guidelines for route selection may help preserve VH rates.

Four glial cells regulate ER stress resistance and longevity via neuropeptide signaling in C. elegans.

The ability of the nervous system to sense cellular stress and coordinate protein homeostasis is essential for organismal health. Unfortunately, stress responses that mitigate disturbances in proteostasis, such as the unfolded protein response of the endoplasmic reticulum (UPRER), become defunct with age. In this work, we expressed the constitutively active UPRER transcription factor, XBP-1s, in a subset of astrocyte-like glia, which extended the life span in Caenorhabditis elegans Glial XBP-1s initiated a robust cell nonautonomous activation of the UPRER in distal cells and rendered animals more resistant to protein aggregation and chronic ER stress. Mutants deficient in neuropeptide processing and secretion suppressed glial cell nonautonomous induction of the UPRER and life-span extension. Thus, astrocyte-like glial cells play a role in regulating organismal ER stress resistance and longevity.

Exploring young women's decisional needs for contraceptive method choice: a qualitative study.

OBJECTIVE: Assisting women with choosing contraceptive methods that meet their needs and preferences is essential to providing patient-centered care, but research to inform interventions supporting method choice is lacking. An assessment of patient decisional needs for contraceptive method choice may provide insight into patient-centered ways to support decision making. STUDY DESIGN: Using the Ottawa Decision Support Framework as a guide, we conducted a qualitative study with semistructured interviews to identify women's decisional needs for choosing a contraceptive method. The sample consisted of 21 women aged 18-29 from an integrated health care delivery system. We employed thematic analysis to identify common themes in the participants' experience. RESULTS: Overall, participants perceived choosing a contraceptive method to be a somewhat difficult decision and described feeling hesitant and unsure. Lack of knowledge of and familiarity with methods and the unpredictability of side effects contributed to participants' hesitancy. Women considered method choice in the context of their lives and their values for various contraceptive attributes, particularly side effects. Participants identified several sources for contraceptive information. Information from friends and family was highly influential. Participants desired both factual and experiential information. CONCLUSIONS: Contraceptive method choice may be difficult for many young women, suggesting a need for decision support. Interventions supporting method choice may be more relevant if they directly address knowledge gaps and uncertainty as well as provide both factual and experiential information on a comprehensive set of contraceptive attributes.
