Mucosa-associated Lymphoid Tissue Misdiagnosis as Glomus Tympanicum.

Middle ear tumors are diverse, but relatively uncommon. The most frequent tumor in the middle ear is glomus tumor, followed by others such as schwannoma and cholesteatoma. We experienced a case of Mucosa-associated lymphoid tissue hyperplasia as a middle ear tumor. The mass behind tympanic membrane appeared a hypervascular tumor, mimicking a glomus tumor, but the form of multiple separate masses in middle ear and mastoid cavity was the distinguishing feature that set it apart from a glomus tumor. Additionally, another characteristic was its tendency to easily shrink under pressure. This characteristic should be considered when encounter a hypervascular looking middle ear mass.

A systematic review and meta-analysis evaluating the impact of obesity on outcomes of abdominal aortic aneurysm treatment.

OBJECTIVE: We sought to evaluate the impact of obesity on perioperative mortality and complication rates in patients undergoing endovascular aortic repair (EVAR) and open surgical repair (OSR) for abdominal aortic aneurysms. METHODS: A systematic review of all studies reporting abdominal aortic aneurysm treatment perioperative (30-day) outcomes in obese patients (body mass index ≥30 kg/m2). The primary outcome was 30-day mortality. Secondary outcomes included cardiac complications, respiratory complications, wound complication, renal complications, and neurological complications at 30 days. These outcomes were pooled for meta-analysis. Analysis first compared obese vs nonobese patients undergoing EVAR and OSR then compared EVAR with OSR in obese patients. RESULTS: We identified seven observational studies with 14,971 patients (11,743 EVAR, 3228 OSR). Obese patients undergoing EVAR had lower 30-day mortality (1.5%) compared with nonobese patients (2.2%) (odds ratio [OR], 0.69; 95% confidence interval [CI], 0.50-0.96; P = .03; I2 = 0%; Grade of evidence: low). In OSR, obese patients (5.0%) had similar 30-day mortality to nonobese patients (5.7%) (OR, 0.92; 95% CI, 0.70-1.20; P = .54; I2 = 0%; Grade of evidence: low). Wound complications were higher in obese patients undergoing OSR (OR, 2.30; 95% CI, 1.74-3.06; P < .001; I2 = 0%; Grade of evidence: low). EVAR was associated with a lower 30-day mortality (1.5%) compared with OSR (5.0%) in obese patients (OR, 0.23; 95% CI, 0.12-0.46; P < .001; I2 = 38%; Grade of evidence: low). Cardiac, respiratory, wound, renal, and neurological complications were also reduced in EVAR. CONCLUSIONS: Obese patients have lower 30-day mortality in EVAR compared with nonobese patients. In OSR, obese patients had similar 30-day mortality but higher wound complications compared with nonobese patients. Obese patients otherwise have similar cardiopulmonary complication rates compared with nonobese patients in both EVAR and OSR. EVAR offers lower 30-day mortality and morbidity compared with OSR in obese patients. This study suggests that EVAR is superior to OSR in obese patients.

Mistrust of Researchers Correlates with Stroke Knowledge among Minority Seniors in a Community Intervention Trial.

BACKGROUND: Medical mistrust influences patients' treatment seeking, adherence, health behaviors, and minority participation in research studies. However, medical mistrust remains understudied within neurological diseases like stroke despite disproportionately affecting minority populations. OBJECTIVE: This study examines the relationship of medical mistrust with stroke knowledge among Black, Latino, Korean, and Chinese-Americans. METHODS: Subjects greater than 60 years were enrolled from senior centers to test a culturally-tailored educational curriculum around stroke risk reduction in a randomized controlled trial. A Trust Physician Scale and a modified Trust of Medical Researchers Scale measured medical mistrust. The Stroke Action Test instrument measured stroke knowledge, focusing on intent to call 911 appropriately when presented with stroke symptoms. RESULTS: Of 225 subjects, 69.5% were female (n = 157) with an average age of 73.7 years (standard deviation 6.7). Blacks had highest trust scores of physicians relative to Latino/a, Korean or Chinese subjects (P< .05). In multivariable analysis, decreased stroke knowledge was associated with decreased researcher trust at baseline (<.05), but not physician trust, when controlling for covariates. Among Latino/a, Korean, and Chinese groups, mainstream acculturation reduced the association between researcher trust and stroke knowledge. A mediation model showed no evidence of physician trust mediating researcher trust. CONCLUSIONS: Among minority seniors participating in a randomized controlled trial, decreased trust of researchers, not physicians, was associated with low baseline knowledge of stroke symptoms. Those least acculturated to US culture may be a particular focus for trust building intervention. Future studies should examine whether researcher mistrust is disproportionately preventing those with the largest knowledge gaps from participating in trials.

Lexical Retrieval of Nouns and Verbs in a Sentence Completion Task.

This study explored noun and verb retrieval using a sentence completion task to expand upon previous findings from picture naming tasks. Participants completed sentences missing either a target noun or verb in the final position. Non-target responses were coded for substitution type, imageability and frequency. Like picture naming, nouns and verbs differed in non-target substitution type-within-category substitutions were primarily nouns and out-of-category substitutions were primarily verbs. Imageability predicted multiple substitution types for both word classes, whereas frequency predicted noun substitution types but not verbs. Findings support theories of noun and verb differences in semantic retrieval, showing the robustness of this effect across methodologies, and shed new light on the influence of imageability and frequency during semantic retrieval.
