ABSTRACT
The Dominican Republic has no recent data on type 1 diabetes (T1D) incidence in children. Therefore, a study was undertaken to determine this in persons aged <15 years (y). Data were collected on all new T1D diagnoses between 2010-2019 from the four institutions caring for children with T1D. Diagnosis was made according to standard criteria. No secondary ascertainment source was available. The trend and the effect of age and sex of T1D incidence was analyzed using Poisson regression. A total of 1224 new cases of T1D were diagnosed <15 y; mean ± standard deviation (range) 122 ± 12 (96-135) cases per year. Age at T1D diagnosis was 8.8 ± 3.7 y, with a significant female preponderance (n = 708, 57.8%, p < 0.001). When examined per 5-y age group, cases were consistently highest in 10-14 y, and lowest in 0-4 y in all study years. Mean crude T1D annual incidence was 4.3 (95% CI 3.5-5.1) per 100,000 population. There was no significant difference between incidence across the country's three departments (regions): Southeast (4.4 [3.4-5.7]/100,000 population), North (4.1 [2.9-5.6]), and Southwest (3.9 [2.4-5.9]). Mean standardized annual incidence was 4.1 (4.1-4.2) per 100,000 population, with no significant trend of increase over the study period. The incidence of T1D in children aged <15 y is relatively low in Dominican Republic, but consistent with the limited data from other countries in the region. However, the incidence is eight times higher than the previous estimate during 1995-1999. Ongoing surveillance is warranted.

Introducción: el síndrome de Poland, conocido también como secuencia de Poland o anomalía de Poland, fue descrito por primera vez por Alfred Poland en 1841. Corresponde a una alteración musculoesquelética congénita, caracterizada por la ausencia total o parcial del músculo pectoral mayor, asociada a anormalidades de la extremidad superior ipsilateral. Objetivo: se presentan 2 casos de niñas que consultaron por asimetría mamaria, en el primer caso una niña de 12 años con ausencia del pectoral mayor y antecedente de postquirúrgicos sindactilia de mano derecha ipsilateral. El segundo caso, una niña de 9 años con asimetría mamaria sin alteración en la extremidad. Conclusión: la anomalía de Poland o secuencia de Poland es una alteración musculoesquelética de presentación infrecuente, de aparición esporádica, de mayor prevalencia en masculinos, afecta generalmente el lado derecho del cuerpo, muy pocas veces amerita tratamiento quirúrgico
Introduction: Poland syndrome, also known as Poland sequence or Poland anomaly, was first described by Alfred Poland in 1841. It corresponds to a congenital musculoskeletal disorder, characterized by the total or partial absence of the major pectoral muscle associated with limb abnormalities ipsilateral superior. Objective: There are 2 cases of girls who consulted for breast asymmetry, in the first case a 12-year-old girl with absence of the pectoralis major and a history of post-surgical syndactyly of the right ipsilateral hand, the second case a 9-year-old girl with breast asymmetry without limb alteration Conclusion: The anomaly of Poland or sequence of Poland is a musculoskeletal alteration with an infrequent presentation, of sporadic appearance, more frequent in males, 10 frequently affecting the right side of the body, very rarely merits surgical treatment.
