Cochlear Meniere's: A Distinct Clinical Entity With Isolated Cochlear Hydrops on High-Resolution MRI?

Objective: Describe the clinical characteristics of patients with isolated cochlear endolymphatic hydrops (EH). Study design: Clinical case series. Setting: Tertiary Neurotology referral clinic. Patients: All subjects presenting to a University Neurotology clinic during a 1-year period from July 2015 until August 2016 who had isolated cochlear EH on MRI. Patients with a history of temporal bone surgery prior to the MRI were excluded. Intervention: High-resolution delayed-intravenous contrast MRI. Main outcome measures: Audiometric and vestibular testing, clinical history analysis. Results: 10 subjects demonstrated isolated, unilateral cochlear hydrops on MRI. None of these patients met the criteria for Meniere's disease. Mean age of the group was 66.4 years and most were males (70%). Unilateral aural fullness (70%), tinnitus (80%), and hearing loss (90%) were frequently observed. Only one patient presented with unsteadiness (10%) and one patient had a single isolated spell of positional vertigo 1 month prior to the MRI (10%) but no further vertigo spells in the 4 years following the MRI. The mean PTA was 37.8 dB which was significantly decreased from the non-affected ear with PTA of 17.9 (p < 0.001). One patient developed vertiginous spells and unsteadiness 4 years after initial presentation and a repeat MRI revealed progression to utricular, saccular and cochlear hydrops. Vestibular testing was obtained in five patients with one patient presenting with 50% caloric paresis and all others normal. The most common treatment tried was acetazolamide in seven patients with 86% reporting subjective clinical improvement. Two out of the 10 patients had a history of migraine (20%). Conclusions: Patients with MRI exhibiting isolated cochlear EH present with predominantly auditory symptoms: mild to moderate low-frequency hearing loss, aural fullness, tinnitus without significant vertigo. Isolated cochlear hydrops is more common in males, average age in mid-60's and there is a low comorbidity of migraine headaches. This contrasts significantly with patients with isolated saccular hydrops on MRI from our prior studies. We believe that isolated cochlear EH with hearing loss but no vertigo is distinct from Meniere's disease or its variant delayed endolymphatic hydrops. We propose that cochlear Meniere's disease represents a distinct clinical entity that could be a variant of Meniere's disease.

Temporal Trends and Regionalization of Acute Mastoiditis Management in the United States.

OBJECTIVE: To describe demographics and to analyze temporal trends in the inpatient management of acute mastoiditis admissions. STUDY DESIGN: Cross-sectional analysis. SETTING: National Inpatient Sample, 2002-2014. PATIENTS: 26,072 nonelective inpatient admissions with primary diagnosis of acute mastoiditis. INTERVENTION: Myringotomy, mastoidectomy, or no procedure. MAIN OUTCOME MEASURES: We described the patient- and hospital-level demographics of acute mastoiditis admissions and the frequency of complications. We evaluated the percentage of patients requiring surgical management. Binary logistic regression was performed to determine whether there was a significant increase in the percentage of patients treated at academic institutions. RESULTS: The majority of patients were ≤40 years old (64.9%) and Elixhauser comorbidity index ≥4 (57.4%); 23.3% (SE 0.8%) presented with complications associated with acute mastoiditis, the most common of which was a subperiosteal abscess (11.5%, SE 0.7%). Among all admissions, 30.9% (SE 1.1%) underwent myringotomy, 13.8% (SE 0.8%) required both myringotomy and mastoidectomy. On multivariate analysis, there was a statistically significant increase in the percentage of mastoiditis admissions to teaching hospitals for all admissions (OR 1.55 [CI 1.22-1.97], p < 0.001) and even more evident for cases with associated complications (OR 1.85 [CI 1.21-2.83], p = 0.004). CONCLUSIONS AND RELEVANCE: A sizeable percentage of patients with acute mastoiditis present with complications which may require surgical intervention. From 2002 to 2014, inpatient care of acute mastoiditis became increasingly regionalized to teaching hospitals, suggestive of increased specialization within certain facilities. This trend may have significant impacts on the cost and subsequent quality of care provided to these patients.

Primary Clear Cell Adenocarcinoma of the Head and Neck: A Population-Based Analysis.

OBJECTIVE: To characterize the epidemiology and clinicopathologic determinants of survival following the diagnosis of clear cell adenocarcinoma in the head and neck region. STUDY DESIGN: Retrospective cohort study. SETTING: The Surveillance, Epidemiology, and End Results registry (1994 to 2014). SUBJECTS AND METHODS: A total of 173 cases were identified. Study variables included age, sex, race, tumor subsite, tumor stage, tumor grade, surgical excision, and regional and distant metastases. Survival measures included overall survival (OS) and disease-specific survival (DSS). RESULTS: Median age at diagnosis was 63 years, 48% were female, and 80.2% were white. Fourteen percent of patients presented with regional lymph node metastases, while 3.3% of patients presented with distant metastases. Most of the tumors presented in the oral cavity, salivary glands, and pharynx. Kaplan-Meier analysis demonstrated OS and DSS of 77.2% and 83.7% at 5 years, respectively. Median OS after diagnosis was 153 months. Bivariate analysis showed that surgical excision was associated with 5-fold increased OS and DSS, whereas advanced age, high tumor grade, advanced stage, larger tumor size, nodal disease, and distant metastases were all significant predictors of decreased OS and DSS. CONCLUSIONS: Clear cell adenocarcinoma is a rare neoplasm that typically affects white individuals in their early 60s, with a generally favorable prognosis. It most commonly arises in the oral cavity, major salivary glands, and pharynx. Surgical excision is associated with 5-fold survival benefit, whereas advanced age, high tumor grade, advanced stage, nodal disease, and distant metastases are independently associated with worse OS and DSS.

An Update on Epidemiology and Management Trends of Vestibular Schwannomas.

OBJECTIVE: To determine the current epidemiology and management trends for patients with vestibular schwannomas (VS). STUDY DESIGN: Retrospective cohort study. SETTING: The Surveillance, Epidemiology, and End Results (SEER) tumor registry. PATIENTS: The SEER database was queried to identify patients diagnosed with VS from 1973 to 2015. Demographics, patient and tumor characteristics, and treatment methods were analyzed. RESULTS: A total of 14,507 patients with VS were identified. The mean age at diagnosis was 55 ±â€Š14.9 years. Age-adjusted incidence from 2006 to 2015 was 1.4 per 100,000 per year and remained relatively stable. Incidence across age varied with sex, as younger women and older men had increased incidences comparatively. A higher percentage of patients underwent surgery alone (43%), followed by observation (32%), radiation alone (23%), and combined radiation and surgery (2%). Age 65 and older was associated with observation (odds ratio [OR] 1.417; p = 0.029) whereas age 20 to 39 and 40 to 49 were associated with surgery (OR 2.013 and 1.935; p < 0.001). Older age was associated with radiation. Larger tumor size was associated with surgery and combined treatment. African American patients and American Indian or Alaskan Native patients were more likely to undergo observation than surgery. CONCLUSIONS: The overall incidence of VS is 1.4 per 100,000 per year and has remained relatively stable. There is a trend toward more conservative management with observation, which may be secondary to earlier diagnosis given widespread use of magnetic resonance imaging. Further studies are necessary to investigate differences in disease patterns and disparities in management.

Prevalencia de sobrepeso y obesidad infantil. Estudio de una cohorte en Castilla y León, España / Prevalence of overweight and obesity in child population. A study of a cohort in Castile and Leon, Spain

Introducción: Varios estudios advierten que el sobrepeso y la obesidad se han convertido en una epidemia con graves consecuencias sobre la salud de la población. El objetivo del presente estudio es estimar la prevalencia de sobrepeso y obesidad en Castilla y León en una muestra de niños a los 6, 11 y 14 años de edad, describir su evolución y su asociación con hábitos de vida y antecedentes. Metodología: Estudio observacional, de cohorte retrospectivo, realizado por los pediatras de la Red Centinela Sanitaria, que se enmarca en un proyecto conjunto con el Centro Nacional de Investigación sobre la Evolución Humana de Burgos para conocer el patrón de crecimiento y desarrollo de la población infantil de Castilla y León. En 2012 se realizó un examen de salud y una recogida retrospectiva a partir de la historia clínica en una muestra de 326 niños, de la cohorte de nacidos en 1998. Resultados: Según los criterios de la OMS, a los 14 años había un 25,3% de sobrepeso entre los niños y un 18,5% entre las niñas. En cuanto a la obesidad, esta afectaba al 8,2 y 4,8%, respectivamente. A los 11 años se produce un pico de sobrepeso en las niñas y de obesidad en los niños. El entorno urbano-no urbano, la calidad y duración del sueño, así como el índice de masa corporal (IMC) de los padres han sido algunos de los factores asociados con el peso de los niños. Discusión: En Castilla y León, como en otras poblaciones de nuestro entorno, existe un grave problema de sobrepeso y obesidad infantil. Para su control, es necesario profundizar sobre los estilos de vida y los antecedentes relacionados con el nacimiento, así como el cálculo de la velocidad de crecimiento en la edad pediátrica

A Population-Based Analysis of Nodal Metastases in Esthesioneuroblastomas of the Sinonasal Tract.

OBJECTIVE: Esthesioneuroblastoma is an uncommon malignancy of the sinonasal tract arising from the olfactory epithelium. Surgical management of the primary site, often via an endoscopic approach, with or without adjuvant radiation, is often curative. There is growing but ultimately limited data regarding management of the neck and the risk of nodal metastases. In this study, we examine the incidence and patterns of esthesioneuroblastoma-related cervical nodal metastases using the Surveillance, Epidemiology, and End Results (SEER) database. METHODS: The SEER registry was queried for all patients with esthesioneuroblastomas diagnosed between 1973 and 2012. Patient data was then analyzed with respect to age, sex, race, modified Kadish stage, grade, survival functions, and nodal disease including specific nodal basins. RESULTS: Three hundred and eighty-one cases of esthesioneuroblastoma with information on nodal metastases were identified. The overall cervical nodal metastasis rate was 8.7%. Level II metastases were most common (6.6%). A total of 4.5% of cases presented with multiple positive nodal basins. Male sex (P = 0.009) and higher tumor grade (P = 0.009) correlated with the presence of level II metastases. There was no association of primary tumor site to the presence of nodal metastases (P > 0.05). The presence of nodal disease significantly predicted poorer overall (P = 0.001) and disease-specific survival (P = 0.017). CONCLUSION: The incidence of nodal metastases in esthesioneuroblastoma at diagnosis is rare, and elective management of the neck remains controversial. Primary tumor site does not appear to predict metastases at specific nodal basins. Higher tumor grade may be a harbinger of eventual nodal metastases.

Treatment outcomes of patients with primary squamous cell carcinoma of the retromolar trigone.

OBJECTIVES/HYPOTHESIS: Squamous cell carcinoma of the retromolar trigone (RMT SCC) is a relatively uncommon primary site for oral cavity malignancy. However, given its proximity to the mandible and buccal mucosa, RMT SCC typically exhibits early invasion and generally presents at an advanced stage. Large-sample studies are needed to assess the epidemiology and clinical outcomes of this tumor. Our aim was to describe the determinants of survival in patients with RMT SCC. STUDY DESIGN: Retrospective cohort study. METHODS: Retrospective, population-based cohort study of patients in the Surveillance, Epidemiology, and End Results tumor registry who were diagnosed with RMT SCC from 1973 to 2012. Primary endpoints were overall survival (OS) and disease-specific survival (DSS). RESULTS: A total of 4,022 cases of RMT SCC were identified. The mean age at diagnosis was 65 years. Thirty-nine percent of cases presented with stage IV disease. The median OS by stages I to IV were 73.7, 52.4, 27.5, and 23.4 months, respectively (P < .05). Overall, 34.3% of patients underwent surgery, 23.5% received radiation therapy, and 34.1% had both surgical and radiation therapy. On multivariate analysis, advanced age, greater tumor size, and advanced stage were associated with worse OS and DSS (P < .05), surgery predicted improved OS and DSS (P < .05), and radiation therapy predicted improved OS only (P < .05). CONCLUSIONS: RMT SCC is an aggressive malignancy that portends a poor prognosis, though early-stage tumors (stages I and II) have significantly improved survival. Any surgical intervention independently predicted higher survival outcomes. There may be a role of dual modality approaches, particularly for larger tumors.

Squamous Cell Carcinoma of the Soft Palate in the United States: A Population-Based Study.

Objectives To describe the incidence and determinants of survival of patients with squamous cell carcinoma of the soft palate (SCCSP) using the Surveillance, Epidemiology, and End Results (SEER) database. Study Design Retrospective, population-based cohort study of patients. Setting SEER cancer registry. Subjects and Methods Patients from the SEER cancer registry from 1973 to 2015 were used to analyze demographics and survival of SCCSP. Results A total of 4366 cases were identified. The average overall survival (OS) and disease-specific survival (DSS) were 68.7 months and 161.3 months, respectively. Multivariate analysis revealed that male sex, stage, and treatment (hazard ratio [HR] = 0.690, P = .019; HR = 1.73, P < .001; HR = 0.64, P < .001, respectively) were independent determinants of better or worse DSS. Age, stage, and treatment (HR = 1.02, P < .001; HR = 1.49, P < .001; HR = 0.66, P < .001; HR = 0.48, P < .001, respectively) were independent determinants of better or worse OS. For stages I, II, and III, radiation alone and surgery alone have nearly equivalent OS. Patients with stage IV disease who underwent both surgery and radiation had a significantly higher median OS at 50.0 months. Conclusion Radiation alone and surgery alone both have nearly equivalent OS benefit for stages I to III, while surgery and radiation provide the most survival benefit for stage IV disease. The large discrepancy between OS and DSS can be due to significant comorbidities. Future studies should aim to address the determinants of quality-of-life variables that help direct treatment decisions and might indirectly affect survival.

The survival impact of surgical therapy in squamous cell carcinoma of the hard palate.

OBJECTIVE: To describe the incidence and determinants of survival of patients with squamous cell carcinoma of the hard palate (SCCHP) between the years of 1973 to 2014 using the Surveillance, Epidemiology, and End Results (SEER) database. METHODS: Retrospective, population-based cohort study of patients in the SEER tumor registry who were diagnosed with SCCHP from 1973 to 2014. Outcomes and measures included overall survival (OS) and disease-specific survival (DSS). RESULTS: A total of 1,489 cases of primary SCCHP were identified. Of those, 53.2% were females and 47.8% presented with stage IV disease. The mean age at diagnosis was 69.8 years. Overall survival at 2, 5, and 10 years was 44%, 33%, and 21%, respectively. A total of 66.2% of patients underwent surgery (with or without radiation therapy [RT]); 20.1% received RT; and 22.4% had both surgical and RT. On multivariate analysis, RT, advanced age, stage, and grade were associated with worse OS and DSS (P < 0.05). Surgical therapy (with or without radiation) was an independent favorable predictor of OS and DSS (P < 0.05). CONCLUSION: SCCHP is relatively infrequent tumor that portends an overall poor prognosis when advanced stage and a greater prognosis when early stage. Surgical therapy was found to be an independent predictor for improved OS and DSS, whereas RT was associated with reduced OS and DSS. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:2050-2055, 2018.

A population-based analysis of verrucous carcinoma of the oral cavity.

OBJECTIVES: To describe the incidence and determinants of survival of patients with verrucous carcinoma (VC) of the oral cavity between the years of 1973 and 2012 using the Surveillance, Epidemiology, and End Results (SEER) database. STUDY DESIGN: Retrospective cohort study using a national database. METHODS: The SEER registry was utilized to calculate survival trends for patients with VC of the oral cavity between 1973 and 2012. Patient data was then analyzed with respect to histopathology, age, sex, race, stage, grade, and treatment modalities (surgery and radiation therapy). Overall survival (OS) and disease-specific survival (DSS) were calculated. RESULTS: A total of 1,481 cases of VC of the oral cavity were identified. The cohort was composed of 50.5% males. The mean age at diagnosis was 69.5 years. The oral tongue was the most common primary site (28.9%), followed by the alveolar ridge (21.4%) and buccal mucosa (19.0%). The vast majority of cases (79.1%) presented with stage I and stage II disease. Nodal disease was present in only 1.6% of cases. The median OS was 94.6 months. Eighty-seven percent of cases underwent surgery, and 11.5% received both surgery and radiation therapy. Overall survival at 2, 5, and 10 years was 83%, 64%, and 42%, respectively. On multivariate analysis, advanced age (P < 0.001) and stage (P < 0.001) were associated with worse OS, whereas surgery improved OS (P = 0.047). CONCLUSION: We provide the first population-based analysis of prognostic factors affecting survival outcomes in patients with oral cavity VC. Verrucous carcinoma of the oral cavity is associated with a generally favorable prognosis. Age, stage, nodal status, and surgical therapy are independent predictors of OS. LEVEL OF EVIDENCE: 4.

Epidemiology and survival outcomes of sinonasal verrucous carcinoma in the United States.

INTRODUCTION: Verrucous carcinoma (VC) is a rare, variant of squamous cell carcinoma with benign cytohistopathologic features and a generally favorable prognosis. Epidemiologic and clinical outcomes data are lacking as a result of limited cases of sinonasal VC. OBJECTIVE: To describe the incidence and determinants of survival of patients with verrucous carcinoma of the sinonasal tract between the years of 1973 to 2014 using the Surveillance, Epidemiology, and End Results (SEER) database. METHODS: The SEER registry was utilized to calculate survival trends for patients with verrucous carcinoma of the sinonasal tract between 1973 and 2014. Patient data then was analyzed with respect to age, sex, race, and treatment modalities (surgery and radiation therapy). Overall survival (OS) and disease-specific survival (DSS) were calculated. RESULTS: A total of 86 cases of VC of the sinonasal tract were identified. The cohort was comprised of 69.8% males. The mean age at diagnosis was 67.4 years. The nasal cavity was the most common primary site (51.2%), followed by the maxillary sinus (40.7%) and nasopharynx (5.8%). The median OS was 97.6 months. 89.5% of cases underwent surgery and 20.9% received both surgery and radiation therapy. Overall survival at 2, 5, and 10 years was 73%, 59%, and 36%, respectively. On multivariate analysis, advanced age (P < 0.05) and primary site (P < 0.05) were associated with worse OS and DSS, respectively. Primary nasopharyngeal tumor site was associated with reduced DSS (P < 0.05). Surgery improved OS (P < 0.001) and DSS (P < 0.001). CONCLUSION: Verrucous carcinoma of the sinonasal tract is associated with a generally favorable prognosis. Age, primary site, and surgical therapy are independent predictors of OS and DSS, respectively. We present the first population-based analysis of sinonasal VC, thus clarifying the prognosis and reinforcing the management of this malignancy. LEVEL OF EVIDENCE: 4.

Epidemiology of Nasopharyngeal Lymphoma in the United States: A Population-Based Analysis of 1119 Cases.

Objectives To describe the incidence and determinants of survival of patients with nasopharyngeal lymphoma (NPL) between 1973 and 2012 using the Surveillance, Epidemiology, and End Results (SEER) database. Study Design Retrospective cohort study using a national database. Methods The SEER registry was used to calculate survival trends for patients with NPL between 1973 and 2012. Patient data were then analyzed with respect to histopathology, age, sex, race, histologic subtype, Ann Arbor stage, and whether radiation therapy was given. Overall survival (OS) and disease-specific survival (DSS) were calculated. Results A total of 1119 cases of NPL were identified. The cohort was composed of 58.8% males. The mean age at diagnosis was 59.3 years. The median OS was 8.2 years. B-cell non-Hodgkin's lymphomas (NHLs) accounted for most cases (77.5%), with natural killer (NK)/T-cell lymphomas comprising 6.0% of cases. A total of 41.5% patients received radiation therapy. OS at 2, 5, and 10 years was 70%, 57%, and 45%, respectively. On multivariate analysis, advanced age and NK/T-cell NHL histologic subtype were associated with worse OS and DSS, while radiation therapy was associated with improved OS and DSS (all P < .05). Conclusion With the exception of NK/T-cell NHL subtypes, NPL is associated with a fair prognosis, with younger age, low Ann Arbor stage, and radiation therapy being independent positive prognosticators for survival.

Nasopharyngeal adenocarcinoma: A population-based analysis.

OBJECTIVES/HYPOTHESIS: To describe the incidence and determinants of survival of patients with nasopharyngeal adenocarcinoma between the years of 1973 to 2012 using the Surveillance, Epidemiology, and End Result (SEER) database. STUDY DESIGN: Retrospective cohort study using a national database. METHODS: The SEER registry was utilized to calculate survival trends for patients with nasopharyngeal adenocarcinoma between 1973 and 2012. Patient data was then analyzed with respect to histopathology, age, sex, race, stage, grade, and treatment modalities (surgery and radiation therapy). Overall (OS) and disease-specific survival (DSS) were calculated. RESULTS: A total of 148 cases of nasopharyngeal adenocarcinoma were identified. The cohort was composed of 54.7% males. The mean age at diagnosis was 59.0years. The median OS was 60.6months. 59.4% of cases were treated with surgery, while 64.1% received radiation therapy. OS at 2, 5, and 10years was 63%, 49%, and 36%, respectively. There was no significant difference in OS and DSS between adenocarcinoma of the nasopharynx versus the sinonasal tract (p>0.05). On univariate analysis, younger age, surgery, surgery and radiation, and lower tumor grade were associated with improved OS and DSS, while papillary subtype, lower stage, and no distant metastasis were associated with improved OS alone (all p<0.05). CONCLUSIONS: Nasopharyngeal adenocarcinoma is an extremely rare malignancy with poor prognosis, with the exception of the papillary subtype. Age, grade, and surgical therapy are predictors of survival.

Small cell carcinoma of the head and neck: A comparative study by primary site based on population data.

OBJECTIVES/HYPOTHESIS: Small cell carcinoma (SmCC) of the head and neck is an extremely rare neuroendocrine malignancy. In this study, we describe the incidence and determinants of survival of patients with SmCC of the head and neck between the years of 1973 and 2012 using the Surveillance, Epidemiology, and End Results database as differed by primary site. STUDY DESIGN: Retrospective, population-based cohort study. METHODS: A total of 237 cases of SmCC of the head and neck were identified, which was divided into sinonasal primaries (n = 82) and all other head and neck primaries (n = 155). Clinicopathologic and epidemiologic variables were analyzed as predictors of overall survival (OS) and disease-specific survival (DSS) based on the Kaplan-Meier method. RESULTS: More than half of sinonasal primaries presented with Kadish stage C or D. On multivariate analysis, surgery was the only independent predictor of improved DSS (P = .008) for sinonasal primaries; in contrast, radiation therapy was a favorable prognosticator for OS (P = .007) and DSS (P = .043) in extrasinonasal sites. Comparison of survival between sinonasal primaries and all other sites demonstrated that sinonasal SmCC had uniformly better OS (P = .002) and DSS (P = .006). CONCLUSIONS: SmCC in the head and neck remains rare, and sinonasal primaries appear to have improved survival compared to other sites. Based on these results, optimal treatment for sinonasal SmCC appears to be surgical therapy, whereas radiation therapy is the preferred treatment for SmCC of other primary sites, particularly the larynx.

Epidemiology of Squamous Cell Carcinoma of the Lip in the United States: A Population-Based Cohort Analysis.

Importance: Squamous cell carcinoma of the lip (lip SCC) composes more than 25% of all oral cancers. Most of the demographic and prognostic indicators for lip SCC are only available through retrospective case series. Objective: To examine the incidence, treatment, overall survival, and disease-specific survival (DSS) of patients with lip SCC. Design, Setting, and Participants: Population-based cohort analysis using the Surveillance, Epidemiology, and End Results database identified patients with lip SCC between January 1, 1973, and December 31, 2012. Main Outcomes and Measures: Overall survival and DSS. Results: A total of 15 832 cases of lip SCC were identified. The cohort was composed of 12 945 men (81.8%) and 2887 women (18.2%). The mean age at diagnosis was 66.1 years. White patients accounted for 98.4% of the cases. Most of the tumors presented in the lower lip (77.8% external and 10.2% mucosal), whereas the external upper lip, mucosal upper lip, and the oral commissure represented 8%, 1%, and 1.2% of all cases, respectively. Of the patients, 91.2% underwent surgical therapy, 7.7% received radiation therapy, and 4.7% received both. Overall survival at 2 years, 5 years, and 10 years was 85.5%, 69.9%, and 50.2%, respectively. Multivariate analysis revealed that age, primary site, T stage, and N stage were determinants of overall survival and DSS. Kaplan-Meier survival analysis showed that SCC of the upper and lower lip had similar overall survival (163.6 months vs 163.8 months) and DSS (418.6 months vs 423.6 months). In contrast, SCC of the oral commissure had significantly lower overall survival (128.5 months) and DSS (286.7 months). Conclusions and Relevance: Our study demonstrates that lip SCC predominantly affects white men in their mid-60s. The determinants of survival for lip SCC include age at diagnosis, primary site, T stage, and N stage. Squamous cell carcinoma of the upper lip and lower lip had similar survival, whereas SCC of the oral commissure was associated with decreased survival.

Segmentation and Classification of Bone Marrow Cells Images Using Contextual Information for Medical Diagnosis of Acute Leukemias.

Morphological identification of acute leukemia is a powerful tool used by hematologists to determine the family of such a disease. In some cases, experienced physicians are even able to determine the leukemia subtype of the sample. However, the identification process may have error rates up to 40% (when classifying acute leukemia subtypes) depending on the physician's experience and the sample quality. This problem raises the need to create automatic tools that provide hematologists with a second opinion during the classification process. Our research presents a contextual analysis methodology for the detection of acute leukemia subtypes from bone marrow cells images. We propose a cells separation algorithm to break up overlapped regions. In this phase, we achieved an average accuracy of 95% in the evaluation of the segmentation process. In a second phase, we extract descriptive features to the nucleus and cytoplasm obtained in the segmentation phase in order to classify leukemia families and subtypes. We finally created a decision algorithm that provides an automatic diagnosis for a patient. In our experiments, we achieved an overall accuracy of 92% in the supervised classification of acute leukemia families, 84% for the lymphoblastic subtypes, and 92% for the myeloblastic subtypes. Finally, we achieved accuracies of 95% in the diagnosis of leukemia families and 90% in the diagnosis of leukemia subtypes.

Hipotiroidismo subclínico en una muestra oportunista de la población de Castilla y León / Prevalence and clinical characteristics of subclinical hypothyroidism in an opportunistic sample in the population of Castile-León (Spain)

Objetivo: Describir la distribución de los valores de la hormona estimulante del tiroides (TSH) y estimar la prevalencia de hipotiroidismo subclínico en la población adulta de Castilla y León. Material y método: Estudio observacional en 45 consultas de medicina de familia de Castilla y León seleccionadas de manera oportunista. Se determinó la TSH en sueros, recogidos por cualquier motivo, de personas ≥35 años de edad. Se realizó análisis de confirmación, incluyendo la tiroxina libre y los anticuerpos antitiroperoxidasa. Resultados: Se realizaron 3957 análisis. El 63,4% eran mujeres. La edad media fue de 61,5 años. La mediana de los valores de TSH fue de 2,3 ¿UI/mL (2, ¿UI/mL en mujeres y 2,1 ¿UI/mL en hombres), con tendencia ascendente con la edad. Los valores de TSH son mayores en los hipotiroidismos subclínicos desconocidos o sin tratamiento que en los tratados. Los valores más bajos se observan en los sujetos eutiroideos. La prevalencia de hipotiroidismo subclínico fue del 9,2% (intervalo de confianza del 95%: 8,3-10,2); en las mujeres fue el triple que en los hombres (12,4% frente a 3,7%) y aumenta con la edad, con un máximo del 16,9% en las mujeres de 45 a 64 años. Conclusiones: La prevalencia estimada de hipotiroidismo subclínico es alta, en los límites superiores reflejados en la literatura. La posibilidad de progresión a hipotiroidismo manifiesto, así como la asociación con diversas enfermedades y factores de riesgo, aconsejan una gestión adecuada de su diagnóstico y tratamiento (AU)

Objective: To describe the distribution of thyroid-stimulating hormone (TSH) values and to estimate the prevalence of subclinical hypothyroidism in the adult population of Castile and León (Spain). Method: An observational study was conducted in an opportunistic sample of 45 primary care centers in Castile and León. TSH was determined in people aged ≥35 years that attended a primary care physician and had a blood test for any reason. Confirmatory analysis included free thyroxine and anti-thyroid peroxidase antibody determination. Results: A total of 3957 analyses were carried out, 63% in women. The mean age was 61.5 years. The median TSH value was 2.3 ¿IU/mL (2.5 ¿IU/mL in women and 2.1 ¿IU/mL in men), with a rising trend with age. TSH values were higher in undiagnosed or untreated subclinical hypothyroidism than in patients under treatment. The lowest levels were found in euthyroidism. The prevalence of subclinical hypothyroidism was 9.2% (95%CI: 8.3-10.2), and hypothyroidism was three times higher in women than in men (12.4% versus 3.7%). Hypothyroidism increased with age, reaching a peak of 16.9% in women aged 45 to 64 years. Conclusions: The prevalence of subclinical hypothyroidism in our sample was high and in the upper limits of values found in previous studies. Proper diagnosis and treatment are important because of the risk of progression to hypothyroidism and the association with multiple diseases and other risk factors (AU)
