Objective: Malignant external otitis (MEO) is an aggressive infection, primarily affecting elderly diabetic patients. It begins in the external ear canal and spreads to adjacent structures. This study investigated the clinical characteristics of patients diagnosed and treated for MEO and analyzed factors affecting patient outcomes.
Study Design: Historical cohort.
Setting: Tertiary medical center.
Methods: Medical records of all patients diagnosed and treated for MEO from 1990 to 2013, were retrospectively reviewed. Clinical features, laboratory, imaging and outcomes were analyzed.
Results: 88 patients were included, mean age was 73±11.5years, 61 (69%) were male. Of these, 75% had diabetes. Mean follow-up was 60months. The most common presenting symptoms were otalgia (89%), external ear canal edema (86%) and otorrhea (84%). Pseudomonas aeruginosa was isolated in 61% of ear cultures. All patients were treated with antibiotics, 22% had surgery and 8% hyperbaric oxygen. Overall survival rate was 38% in 5years, with disease specific mortality 14%. DM, facial nerve palsy, positive CT scan and age above 70 were found to correlate and predict disease-specific mortality.
Conclusions: MEO carries a grave prognosis. The presence of two or more of the following features, DM, facial nerve palsy, positive CT scan and age above 70, predicts poor outcome, and highlights the need for prolonged, vigorous treatment.

Neutrophils were historically considered a homogenous population of cells with functions limited to innate immunity against external threats. However, with the rise of immunotherapy, recent works have shown that neutrophils are also important actors in immuno-oncology. In this context, neutrophils appear as a more heterogenous population of cells.

Trophoblast glycoprotein (TPBG) plays a significant part in the growth of specific cancers, yet its connection to gastric cancer (GC) remains uncertain. This research seeks to analyse the fluctuation in TPBG levels in GC and evaluate how TPBG expression relates to the prognosis of GC patients. TPBG expression in GC and normal gastric tissues was investigated in The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) database, further extracting the immunohistochemistry images from HPA database and validating by Western blot.

Background: Thymomas and thymic carcinomas are rare and aggressive thymic tumors that are usually detected in advanced stages. Surgery is the mainstay of treatment; however, the role of surgery in advanced disease is controversial due to factors such as myasthenia gravis; thus, decisions about whether to perform surgical interventions are complex. Further studies need to be conducted to explore the potential benefits of surgery in the treatment of advanced thymic tumors.

Background: Breast cancer is the most common malignant tumor among women, with an increasing incidence each year. The subtypes of human epidermal growth factor receptor 2 (HER2)-negative breast cancer, classified as HER2-low and HER2-zero based on HER2 receptor expression, show differences in clinical characteristics, therapeutic approaches, and prognoses. Distinguishing between these subtypes is clinically valuable as it can impact treatment strategies, including the use of next-generation antibody-drug conjugates (ADCs) targeting HER2-low tumors.

A 5-year-old male with xeroderma pigmentosum from Honduras presented with a rapidly growing mass on the left post-auricular neck, associated with left-sided hearing loss. MRI revealed a large mass with invasion of the external auditory canal, temporal bone, and metastasis to lymph nodes. Biopsy confirmed moderately differentiated squamous cell carcinoma (SCC).
