ABSTRACT

El síndrome de Goltz llamado también hipoplasia dérmica focal es una rara dermatosis que fue definida por primera vez por Goltz en el año 1962. Se la considera una genodermatosis de presentación esporádica (95% de los pacientes) aunque se han reportado casos de transmisión familiar. Compromete estructuras derivadas del mesodermo y ectodermo con predominio en el sexo femenino acompañada de herencia dominante ligada al cromosoma X. La mutación en el gen PORCN (locus Xp11.23) es letal en la mayoría de varones. La importancia de su publicación radica en su baja frecuencia y las manifestaciones clínicas características que ayudan al establecer el diagnóstico.


Goltz syndrome, also called focal dermal hypoplasia, is a rare dermatosis that was first defined by Goltz in 1962. It is considered a genodermatosis with sporadic presentation (95% of patients) although familiar aggregation has been reported. It compromises mesodermal and ectodermal structures, most frequently in female patients, its inheritance mode is dominant X linked. The mutation in the PORCN gene (locus Xp11.23) is lethal in the majority of males. The importance of its publication lies in its low frequency and clinical characteristic that helps in establishing the correct diagnosis.

ABSTRACT

Resumen Introducción: el Helicobacter pylori se asocia con patologías gastrointestinales, el incremento en la resistencia a los antibióticos utilizados para su erradicación es alarmante a nivel mundial. En este estudio se determinó la susceptibilidad a 5 antibióticos utilizados en la terapia de erradicación de H. pylori aislado de una población adulta con dispepsia recurrente en Quito, Ecuador. Materiales y métodos : previa aceptación del consentimiento informado, se tomaron biopsias de cuerpo y fondo gástrico de 210 pacientes con dispepsia y mediante cultivo se recuperaron los aislados de H. pylori identificado mediante pruebas bioquímicas. La susceptibilidad al metronidazol, claritromicina, amoxicilina, tetraciclina y levofloxacina se realizó por concentración mínima inhibitoria (CMI). Todos los cultivos se correlacionaron con el estudio histopatológico. Resultados: se recuperaron 89 aislados de H. pylori. Se obtuvo un kappa de 0,9 entre el cultivo y el estudio histopatológico. El porcentaje de cepas con resistencia antibiótica fue: metronidazol (63%), claritromicina (66%), amoxicilina (43%), tetraciclina (36%) y levofloxacina (54%). Conclusión: estos hallazgos demuestran la alta resistencia a los antibióticos usados para la erradicación de H. pylori, varios factores como el consumo indiscriminado de antibióticos, terapia previa, entre otros podrían estar involucrados.


Abstract Introduction: Worldwide, helicobacter pylori is associated with gastrointestinal pathologies, but increasing resistance to antibiotics used for its eradication is causing alarm. This study determined susceptibility of H. pylori to five antibiotics used in eradication therapy in an adult population with recurrent dyspepsia in Quito, Ecuador. Materials and methods: After patients provided informed consent, biopsies were taken from the gastric corpus and fundus of 210 patients with dyspepsia. H. pylori isolates identified by biochemical tests were recovered from cultures of biopsy samples. Minimal inhibitory concentrations (MIC) of metronidazole, clarithromycin, amoxicillin, tetracycline and levofloxacin were tested to indicate susceptibility. All cultures were correlated with the histopathological study. Results: H. pylori isolates were recovered from 89 cultures. A kappa of 0.9 was obtained between the culture and the histopathological study. The percentage of strains with antibiotic resistance were 63% for metronidazole, 66% for clarithromycin, 43% for amoxicillin, 36% for tetracycline and 54% for levofloxacin. Conclusion: These findings demonstrate high levels of resistance to the antibiotics used for eradication of H. pylori. Several factors including indiscriminate consumption of antibiotics and previous therapy may be involved.

ABSTRACT

Nereis garwoodi n. sp. is described on the basis of eight syntype specimens (six atokous and two heteronereis) collected in Bahía Chetumal, Mexican Caribbean coast, and the variability in the paragnath numbers in the pharynx is established using 180 specimens; paragnath numbers are I:10(SD = 1.9); II:30 (SD = 2.6); III:41 (SD = 5.2); IV:29 (SD = 3.5), V:1, VI:4, VII-VIII: > 30. Its eyes are big and its longest tentacular cirri reaches setiger 11. A revised key to species of Nereis recorded from the Grand Caribbean Sea is included.

ABSTRACT

Sera from 9,254 individuals that presented at one of three outpatient clinics in Quito, Ecuador were assayed by indirect hemagglutination for the presence of antibodies reactive with antigens from Taenia solium cysts. Immunoblot anlysis of 81 selected sera with IHA titers ranging from 0 to 1,028 showed that a titer of maior ou igual a 32 was suggestive of exposure to the parasite. Nine percent (9 por cento) of the 9,254 patients had titers of 32 or greater. Of 3,503 sera from one clinic, which included sera from food handlers undergoing yearly physicals, 390 (11 por cento) were positive. In addition, a correlation with age was seen in some, but not all, populations. In situations where age-related effects were noted, the highest incidence was seen in the youngest (0-20 years) and in the oldest (51-60 years) group. Thus, a resurgence of infection after a period of lower prevalence may be developing. Overall, this study shows that cysticercosis is relatively common and potentially a serious health problem in this region.

ABSTRACT

Se presenta la experiencia obtenida mediante la exploración ultrasonográfica como procedimiento diagnóstico inicial de las lesiones neoplásicas, inflamatorias y obstructivas del tracto gastrointestinal en 31 pacientes evaluados prospectivamente y en quienes los exámenes complementarios posteriores permitieron establecer una patología específica. Se establecen los patrones sonográficos de aquellas lesiones cuya etiología fue luego corroborada por estudios complementarios. En veintiocho, los hallazgos fueron suficientes para orientar o afirmar la existencia de lesiones, distribuídas así: 14 neoplasias (13 malignas y 1 benigna), 6 procesos inflamatorios (3 de intestino grueso y 3 apendicitis aguda), 8 procesos obstructivos (5 de origen gástrico, 1 duodenal y 2 de intestino delgado). Hubo 3 errores diagnósticos. La rapidez del método, su no invasividad, la posibilidad de repetirlo cuantas veces sea necesario y poder observar la respuesta y evolución del tratamiento indicado, hacen que sea útil para orientar y en algunos casos para establecer el diagnóstico de lesiones del tubo digestivo
