Sepsis in Children in Latin America: Gaps, Inequities, and Improvement Strategies.

ABSTRACT: Pediatric sepsis is a worldwide public health issue because of its high mortality rate, which increases even more in low-income countries. In this article, we review the Latin American background, the burdens of pediatric sepsis in Latin America, and the Caribbean, as well as some strategies that could help improve the outcomes of sepsis in these regions from a public health view.

Double Trouble: A Unique Case of Hypercalcemia Caused by Two Underlying Etiologies.

Hypercalcemia has a variety of causes, with primary hyperparathyroidism and malignancies being the most frequently reported. We present the case of a patient presenting with chronic abdominal pain, constipation, and weight loss who was found to have hypercalcemia. The patient was initially diagnosed with colonic actinomycosis, but further investigations revealed an intra-abdominal diffuse large B-cell lymphoma (DLBCL). We suspect that the leading cause of hypercalcemia was the DLBCL, likely exacerbated by actinomycosis. Actinomycosis and DLBCL can have a similar presentation, so misdiagnosis or coexistence of both conditions should be suspected when a lack of response to one specific therapy is observed.

Hydrometrocolpos and Post-axial Polydactyly Complicated With Acute Intestinal Obstruction and Hydroureteronephrosis.

This report presents a case of a one-month three-day-old full-term female infant with hydrometrocolpos (HMC) and post-axial polydactyly whose first clinical sign was acute intestinal obstruction and hydroureteronephrosis, caused by compression of the structures due to the increasing size of the cystic-like pelvic mass. This is the first report of HMC with post-axial polydactyly complicated with acute intestinal obstruction in Peru. It raises importance on prenatal diagnosis, management and complications of HMC. Although it is rare, clinicians should have it as an option when discussing abdominal cystic masses in neonates to perform early management and avoid complications. Continuous follow-up should be carried out on patients presenting with HMC and post-axial polydactyly to assess for Bardet-Biedl syndrome, which could affect different systems in those patients long-term.

Teenager with a Primary Renal Lymphoma: A Case Report.

We report a case of an 18-year-old male patient who was diagnosed with primary renal lymphoma (PRL) through biopsy findings and imaging studies. The patient presented with clinical manifestations of distal renal tubular acidosis including polyuria, polydipsia, lower limb weakness, involuntary weight loss, asthenia and dyspnea. No personal background or relevant medical history was reported. A kidney biopsy showed high grade immature B-cell lymphoproliferative process (Non-Hodgkin's Lymphoma) with a Ki67 value greater than 90%. Complementary studies excluded primary lymphoid migration sites, which confirmed the diagnosis of PRL. The oncology unit initiated treatment with a combination of medications due to lack of protocols for the specific treatment. Besides the fact that this condition is rare, it also shows a unique symptoms presentation and non-typical findings in imaging methods. Also, it is important to underline the fact that the treatment is not yet specified for such type of cancer and different combinations are needed to control the disease.
