RESUMEN
Purpose@#Studies about the effect of radiation therapy (RT) on immune cells are usually limited to a high-grade glioma mostly exposed to chemotherapy and a high dose of steroid which also could affect immune cells. The purpose of this retrospective analysis of low-grade brain tumor patients treated by RT alone is to determine significant factors influencing neutrophil-to-lymphocyte ratio (NLR), absolute neutrophil counts (ANC), and absolute lymphocyte counts (ALC). @*Materials and Methods@#A total of 41 patients who received RT between 2007 and 2020 were analyzed. Patients who received chemotherapy and high-dose of steroid were excluded. ANC and ALC were collected before starting RT (baseline) and within one-week before ending RT (post-treatment). Changes of ANC, ALC, and NLR between baseline and post-treatment were calculated. @*Results@#ALC decreased in 32 patients (78.1%). NLR increased in 31 patients (75.6%). No patients developed grade 2 or higher hematologic toxicities. The decrease of ALC was significantly correlated with the dose to brain V15 in a simple and multiple linear regression (p = 0.043). Brain V10 and V20 adjacent to V15 were also marginally significant factors determining the reduction of lymphocytes (p = 0.050 and p = 0.059, respectively). However, it was difficult to find predictive factors affecting changes of ANC and NLR. @*Conclusion@#In low-grade brain tumor patients who are treated by RT alone, ALC decreased and NLR increased in three-fourth of patients, although the magnitude was minimal. The decrease of ALC was mainly affected by low dose to the brain. However, RT dose was not correlated with changes of ANC or NLR.
RESUMEN
Testicular torsion in neonates is a urologic emergency with an incidence of 6.1 per 100,000 live births. Incarcerated inguinal hernia is also an emergency with an incidence of approximately 6% to 31% in children with inguinal hernia. Functional testicular torsion from an incarcerated inguinal hernia is a rare event in children, often not considered in the initial evaluation. A 19-day-old newborn boy was admitted to our neonatal intensive care unit after visiting a primary clinic. He presented with inconsolable crying and right scrotal swelling. Upon initial physical examination, a hard palpable mass and swelling was found in the inguinoscrotal region, accompanied with redness and warmth of the scrotum. Scrotal ultrasound with color Doppler showed inguinal hernia with strangulation and scanty blood flow to the testis. The patient underwent a right orchiectomy and partial resection of the affected small bowel. Surgical findings confirmed a testicular torsion and incarcerated inguinal hernia with testis with small bowel necrosis. Here, we report a rare case of a newborn with functional testicular torsion as a result of prolonged spermatic cord compression due to incarcerated inguinal hernia.
