Currently, the debate on the usefulness of Neutrophil to Lymphocyte Ratio (NLR) as a predictor of complications in acute diverticulitis (AD) remains open, especially, the relation to the severity of the disease, the clinical impact, and the necessity of minimally invasive or emergency surgical procedures. On the other hand, its diagnostic efficacy has not been studied even in our field. The objective of the present study was to determine the utility and diagnostic precision of NLR in complicated acute diverticulitis (cAD). Descriptive, retrospective cohort and analytical study. Patients older than 18 years with a diagnosis of AD were included, from 2013 to 2018. Demographic variables, days of hospitalization, leukocyte count, neutrophils, lymphocytes, ESR, CRP, and NLR were analyzed. The sensitivity and specificity for the diagnosis of cAD were determined using ROC curves. 325 patients were included. Of these 196 (60%) were men. The median age was 52 years. A total of 30 (9%) were categorized as cAD. The patients with cAD presented mean values in the leukocyte count (14.02 ± 4.49 × 109/l; p < 0.01), CRP (119.60 ± 87.67; p < 0.01) and NLR (7.61 ± 4.03; p < 0.01). An NLR cutoff value ≥ 4.2 was identified as the most appropriate to distinguish cAD, with a sensitivity of 80%, a specificity of 64%, NPV of 96%, and PPV of 18%. NLR is a predictive marker of cAD, with a cut-off point of 4.2 being the best diagnostic approach.

Introduction: COVID – 19 emerged as a global pandemic in 2020 and affected the teaching methods at all levels. Surgical education has also been significantly affected by this pandemic, but the effect remains unknown. We developed a survey in order to obtain more information on how this pandemic affected the training and education of surgical residency programs. Material and methods Cross-sectional study. We surveyed 195 residents of various surgical programs, from August 20th to September 30th, 2020, in Córdoba, Argentina. The effect of the COVID – 19 pandemic was analyzed on surgical training, on the academic program, and professional burnout. Results: The volume of surgical cases performed during the pandemic decreased dramatically, affecting mainly residents of lower years. Comparing the number of cases (>7) that residents carried out per week (Pre pandemic vs pandemic), we found that PGY – 1: 47% vs 9%; p = 0.01 and PGY – 2: 46% vs 8%; p = 0.03. 83.2% reported that the impact of the pandemic affected their surgical training negatively and 45% were not adequately trained to carry out their surgical activity in the residency program. On the other hand, 71.3% affirmed that this health emergency allowed them to dedicate more time to the development of their academic training. Conclusion: This is the first cross – sectional survey study that shows the impact of the pandemic on surgical residences during the first wave in Argentina. Surgical training performed by residents had a negative impact.

Introduction and importance: Granular cell tumors (GCT) are rare neoplasms. The most common places are the head and neck. The larynx accounts for 3-10% of cases. Presentation of case: We present the case of a man who consulted our Department of Otorhinolaryngology due to long-term progressive dysphonia without dyspnea or dysphagia. Fibrolaryngoscopy revealed a tumor that affected the left vocal cord. The tumor was surgically resected. The histopathological report revealed a laryngeal GCT. Fourteen months after surgery, the patient had no recurrence. Clinical discussion: Patients with GCT of the larynx typically have persistent hoarseness, stridor, dysphagia and otalgia, but can also be asymptomatic. A definitive diagnosis is provided by histopathology with immunohistochemistry, and the treatment of choice is surgical resection. Unlike the literature, our report concerns a young man. Conclusion: Granular cell tumor is a rare tumor of the larynx and should be considered a differential diagnosis in all adult men with long-standing dysphonia. Highlights:

Diverticulosis of the small bowel is a rare entity. It can cause acute, complications such as diverticulitis, perforation, intestinal bleeding and obstruction. During the pandemic, patients were reluctant to visit hospitals for fear of contracting coronavirus disease 2019. This caused the patients to wait until the extreme deterioration of many acute surgical conditions. An 83-year-old man with multiple comorbidities showed up at the emergency department with generalized abdominal pain of 7 days of evolution. The computed tomography scan revealed a large distention of the small intestine and a small inflammatory abscess. He was transferred to the operating room where a segment of the jejunum affected by multiple diverticula located on the mesenteric side of the intestine and a mesenteric abscess related to a perforated jejunal diverticulum were identified. Complicated jejunal diverticulosis is a difficult entity to diagnose, which can cause significant morbidity and mortality. To avoid this, its timely diagnosis is essential.
