An epiglottic cyst is a type of benign tumor that is formed due to the obstruction of the mucinous duct and the retention of glandular secretion. In such cases, the glottis is not visible as it is covered by the enlarged epiglottic cyst. When conventional anesthesia is administered in such patients, they might have difficulty ventilation since the epiglottic cyst can easily form a flap and move with external pressure changes and can cause the blockage of the glottis due to the loss of consciousness and the relaxation of the throat muscles of the patient. If endotracheal intubation is not initiated and effective ventilation is not established, the patient may suffer from hypoxia and other accidents. ⋯ Patients with epiglottic cysts are more likely to have difficult airways after induction of anesthesia. Anesthesiologists should take preoperative airway assessment seriously, efficiently handle difficult airway and intubation failure, and make quick and correct choices to ensure patient safety.

Cyclin-dependent kinase 4/6 inhibitors are promising candidates for patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer. However, current international guidelines recommend endocrine therapy alone or with HER2-targeted therapy to treat HER2-positive and hormone receptor (HR)-positive metastatic breast cancer in patients who cannot tolerate first-line chemotherapy. Moreover, data on the effectiveness and safety of cyclin-dependent kinase 4/6 inhibitors combined with trastuzumab and endocrine therapy as a first-line treatment for HER2-positive and HR-positive metastatic breast cancer are limited. ⋯ We believe that trastuzumab, leuprorelin, letrozole, and palbociclib is a feasible and effective treatment for HER2-positive and HR-positive metastatic breast cancer in premenopausal patients who cannot tolerate first-line chemotherapy.

Observational Study
Prevalence and risk factors for severe linezolid-associated thrombocytopenia in pediatric patients: An analysis of a public database.
Linezolid is widely used in various clinical settings. Studies have revealed that it may cause thrombocytopenia in adults. However, the correlation between the use of linezolid and thrombocytopenia in pediatric patients is still unclear. ⋯ Multivariate analysis also revealed that the occurrence of severe thrombocytopenia was significantly associated with concurrent use of carbapenem (odd ratio = 4.058; 95% confidence interval: 1.012-16.274; P = .048) and piperacillin/tazobactam (odd ratio = 5.335; 95% confidence interval: 1.117-25.478; P = .036). 75% of patients (9/12) developed severe thrombocytopenia within the first 7 days of linezolid use. The concomitant use of carbapenem and piperacillin/tazobactam was associated with an increased probability of severe thrombocytopenia in pediatric patients undergoing linezolid treatment. Further prospective clinical studies are required, and more detailed mechanisms of blood toxicity in pediatric patients must be investigated.

This study explored whether the risk of thyroid cancer in Asian women is associated with consumption of oral contraceptives (Diane-35). We conducted a population-based, retrospective cohort study using the Taiwan National Health Insurance Research Database. From the database, 9865 women aged 18 to 65 years who were prescribed Diane-35 between 2000 and 2012 were included in the Diane-35 group, and 39,460 women who were not prescribed Diane-35 were included in the comparison group and were frequency-matched by age and index year. ⋯ In subgroup analysis, patients aged 30 to 39 years showed a higher hazard ratio of developing thyroid cancer after consuming Diane-35 than those in the comparison group (HR: 5.58, 95% CI: 1.84-16.91). The study provides evidence that women aged 30 to 39 years consuming Diane-35 are at increased risk of thyroid cancer. Nevertheless, a larger population with a longer follow-up may be necessary to confirm causality.

Hypercalcemia is a common complication of many granulomatous diseases but is not typically associated with leishmaniasis. Here we report an unusual case of hypercalcemia during the initiation of antiviral therapy in a patient with acquired immunodeficiency syndrome coinfected with visceral leishmaniasis. ⋯ This case highlights an unusual presentation of immune reconstitution inflammatory syndrome, in which proinflammatory cytokine signaling during the restoration of cellular immunity may have led to increased ectopic calcitriol production by granuloma macrophages, thereby altering bone-mineral metabolism and driving hypercalcemia.
