RESUMO
Introduction Expressive language problems are common amongst preschoolers both in the general population (15-20%) and in clinical settings (50-75%); furthermore, these problems are often not detected. Language problems require attention since they are associated with severe developmental disorders such as autism (Au), Asperger's syndrome (AS), attention-deficit hyperactivity disorder (ADHD) and mental retardation. In theory, language development, specifically expressive vocabulary, associated to psychiatric disorders could be identified with a scale that measures expressive language. Objectives 1. To determine the frequency of language delay in a sample of Mexican children with typical development in the community. 2. To determine the vocabulary level for autism, Asperger's syndrome, ADHD and other psychiatric disorders through the use of the Language Development Survey (LDS). 3. To analyze if differences in vocabulary ratings among the clinical subgroups can be detected with this instrument. Materials and methods The sample consisted of: A community group with typical development (TDG) (n=302) and a clinical group (CG) (n=55); both groups had an age range of 2-5 years. The clinical group was subdivided into 4 clinical subgroups based on DSM-IV criteria for: autism, Asperger's syndrome, ADHD and other psychiatric disorders (OPD) (enuresis, encopresis, separation anxiety). Exclusion criteria were: deafness, hypoacusia and other sensorial disorders and mental retardation. A semi-structured interview based on DSM-IV criteria was designed ad hoc to diagnose: autism, Asperger's syndrome, ADHD (inattentive, combined or hyperactive impulsive varieties), specific phobia disorder, tics (transitory, chronic and Tourette's syndrome), dysthymic disorder, depression, enuresis, separation anxiety disorder based on parent information. The clinical evaluation included a semi-structured play session with age-appropriate didactic material. Discrepancies in diagnosis were resolved by consensus. All interviews were conducted by an experienced clinician. The number of bulbs in the household was used to measure socioeconomic status (SES). The LDS is a list of words that explores children's vocabulary based upon parental report. The original survey has a Cronbach's alpha coefficient of 0.99, test-retest coefficient of 0.97-0.99, and a sensitivity and specificity of 86-90%. Language delay (LD) was defined as ≤50 words, as recommended by several researchers. All parents signed an informed consent form and answered the LDS. Statistical analysis. Categorical data was analyzed using a χ2 analysis; continuous data such as age, socioeconomic status, and LDS score, were analyzed using t-tests. To analytically compare the LDS group medians, a Kruskal-Wallis test was used, since the variable distribution violated the normality distribution requirements for parametric tests. For the post hoc tests, a Tamhane analysis was used for groups of different sizes. Differences were considered statistically significant if they had a p<0.05. Results The groups were similar for variables such as child's age, parents' age and the LDS median between the normal development group and the clinical group t(355)=1.12, p=.26. The proportion of male children was greater in the clinical group (CG) than in the TDG, 76.4% vs. 53%, χ2(1,N=357)=10.63, p<.001. SES was higher for the TDG (M=7.2, SD=4.2) than for the CG (M=5.8, SD=3), p<.005. The father's age (r=.15, p<.009), the mother's age (r=.16, p<.003) and the SES (r=.13, p<.01) were correlated to the LDS score. Additionally, father's and mother's age were strongly correlated (r=.72, p<.0001) and the mother's age showed small correlations with the socioeconomic status (r=.15, p<.004). The mother's age was correlated with the child's vocabulary for both sexes (males: r=.16, p<.04, females: r=.16, p<.02), and vocabulary was significantly correlated with the SES, only for the males. Language delay frequency in the TDG was 21.2%, and 23.6% for the CG, χ2(1,N=352)=1.03, p<0.59. By sex, males in both groups exhibited a greater frequency of LD [TDG: 21.6% males vs. 20.7% females, χ2(1,N=302)=.154, p<0.926; CG: 26.2% males vs. 15.4% females, χ2(1,N=55)=.642, p<0.423]. The autism subgroup had the lowest vocabulary rating (M=85, SD=78.68), followed by the OPD subgroup (M=149, SD=121), whose rating was very similar to the typically development group (M=179, SD=105). The Asperger group (M=259, SD=27) had a similar score to the ADHD group (M=286, SD=100.2), which had the highest vocabulary score of all. The Kruskal-Wallis test for median differences was significant [H(4)=17.47, p<.002]. Multiple contrast comparisons and Tamhane's post hoc analysis showed that only the contrast between the autism and the ADHD subgroups (means: 85 vs. 286, respectively) was significant (ANOVA Tamhane post hoc, p<.01).
Introducción Aun cuando los problemas de lenguaje expresivo son muy comunes tanto en la población general (15-20%) como en la clínica (50-75%), su detección es insuficiente. Los problemas de lenguaje requieren atención debido a su comorbilidad con problemas graves del desarrollo como el autismo, el trastorno de Asperger, el trastorno por déficit de la atención e hiperactividad (TDAH) y el retraso mental. En teoría, el vocabulario asociado a estos trastornos psiquiátricos podría identificarse con un instrumento que midiera el vocabulario expresivo. Objetivos 1. Determinar la frecuencia de atraso del lenguaje (AL) (SDL ≤50 palabras) en un grupo con desarrollo típico de la comunidad. 2. Determinar el nivel de vocabulario para los subgrupos de: autismo, trastorno de Asperger (TA), TDAH y otros trastornos psiquiátricos (OTP) por medio del sondeo del desarrollo del lenguaje (SDL). 3. Analizar si el SDL puede discriminar entre los subgrupos clínicos. Sujetos y método La muestra estuvo compuesta por: un grupo de la comunidad con desarrollo típico (GDT) (n=302), y un grupo clínico (GC) (n=55), con un rango de edad de 2-5 años. Se formaron cuatro subgrupos clínicos: autismo, trastorno de Asperger, TDAH y un grupo de OTP (enuresis, encopresis, ansiedad de separación). El SDL es una lista de palabras que identifica el padre sobre el vocabulario de los niños que tiene un coeficiente de alpha de Cronbach de (.99), un test-retest de .97 a .99 y una sensibilidad y especificidad de 86-90%. Se utilizó la definición de atraso de lenguaje (AL) basada en un punto de corte de ≤50 palabras. Análisis estadístico. Los datos categóricos fueron analizados mediante la prueba de chi-cuadrada y para las medidas continuas como la edad, el MSE y el puntaje del SDL se usaron pruebas t de Student. Para el análisis del contraste de las medianas del SDL de los grupos se aplicó una prueba de Kruskal-Wallis. Resultados Los grupos fueron semejantes para las variables como edad del niño, edad de los padres y la media del SDL. La frecuencia de AL (≤50 palabras) fue de 21.2% para el GDT y de 23.6% para la población clínica. Por sexo, los varones presentaron mayor frecuencia de atraso de lenguaje (GDT): 21.6% masculino vs. 20.7% femenino (p<0.926), GC: 26.2% masculino vs. 15.4% femenino (p<0.423). El vocabulario del grupo de autismo fue el menor de todos (Mdn=85, DE=78.68) seguido del grupo de OTP (Mdn=149, DE=121.0) que presentó un desempeño muy semejante al grupo de la comunidad (GDT) (Mdn=179, DE=105.0). El grupo de Asperger (Mdn=259, DE=127) tuvo un puntaje cercano al grupo de TDAH (Mdn=286, DE=100.25). La prueba de Kruskal-Wallis para la diferencia en las medianas fue significativa (p<.002) pero sólo el contraste entre el grupo de autismo y de TDAH (Mdn=85 vs. Mdn=286, p<.01) fue significativo. Discusión La frecuencia de AL para el GDT fue de 21.6% y para el GC fue de 23.6%. El SDL fue sensible en la detección del nivel de vocabulario entre los grupos y los resultados fueron congruentes con el desempeño esperado con algunas excepciones. Los niños con TDAH expresaron un mayor número de palabras comparados con el GDT. El único contraste significativo fue la comparación entre el grupo de TDAH y el autismo. El vocabulario del grupo de Asperger fue mejor que el de autismo, pero esta diferencia no alcanzó significancia estadística. Conclusiones La versión mexicana del SDL es un instrumento de tamizaje útil para identificar el atraso del lenguaje en los niños preescolares. Este estudio muestra que el atraso de lenguaje en un niño preescolar con TDAH es una indicación para profundizar en el diagnóstico del autismo. Tampoco deben pasarse por alto otros trastornos que pueden acompañar o no el TDAH como los trastornos del lenguaje específicos (pronunciación, expresión, comprensión). El SDL mide el vocabulario y no identifica alteraciones del lenguaje cualitativas más complejas asociadas al trastorno de Asperger.
RESUMO
We report the clinicopathologic features of 13 cases of intramucosal carcinoma (IMC) of the gallbladder. All IMCs were incidental findings in cholecystectomy specimens for cholelithiasis. However, one of the patients had a carcinoma of the pancreas, and the gallbladder incidentally removed during the Whipple procedure showed an IMC. Another patient had a small cell carcinoma of the gallbladder, and one of the sections showed an IMC. Of the IMCs, 10 were well-differentiated adenocarcinomas, 1 was a moderately differentiated adenocarcinoma, 1 was an undifferentiated carcinoma, and 1 was a squamous cell carcinoma. Of the patients, 8 were disease-free from 3 to 11 years, and 2 patients died, one as a result of the pancreatic ductal carcinoma and the other with disseminated metastases of the small cell carcinoma. The follow-up of another patient was too short to be significant. Two patients were lost to follow-up. Our findings suggest that a simple cholecystectomy is a curative procedure for IMCs of the gallbladder.

Cutaneous angiosarcoma is an aggressive malignant mesenchymal vasoformative neoplasm that accounts for 1% of all soft tissue sarcomas. Using data from the National Cancer Institute's Surveillance, Epidemiology, and End Results program, we analyzed the demographics and survival of cutaneous angiosarcoma. The Surveillance, Epidemiology, and End Results program recorded 434 cases of cutaneous angiosarcoma from 1973 to 2007. The incidence was nearly the same in men (222 cases) and women (212 cases). Most patients were white (88%) with a mean age of 73 years. African Americans made up only 4% of the cases. Two hundred seventy (62%) cases were tumors of the head and neck, whereas 106 (24%) cases arose in the skin of the trunk. Grade was recorded in 194 cases (45%): 28 were grade I, 44 were grade II, 60 were grade III, and 62 were grade IV. Survival rates of cutaneous angiosarcoma correlated with age, anatomical site, and stage of disease. Patients younger than 50 years had a 10-year relative survival rate of 71.7%, whereas patients 50 years and older had a 36.8% 10-year survival rate. Tumors of the scalp and neck resulted in a 13.8% 10-year relative survival rate, whereas tumors arising in the trunk resulted in a 75.3% 10-year survival rate. Tumors localized to the skin had better prognosis (53.6% 10-year relative survival rate) than those with regional or distant stage (19.0% and 6.2%). Twenty-six percent of patients with angiosarcoma had a prior primary. Cutaneous angiosarcomas arise predominantly in the head and neck of white individuals older than 60 years.
