Blood and adipose-resident eosinophils are defined by distinct transcriptional profiles.

Eosinophils are granular leukocytes of the innate immune system that play important functions in host defense. Inappropriate activation of eosinophils can occur in pathologies such as asthma and esophagitis. However, eosinophils also reside within adipose tissue, where they play homeostatic roles and are important in the activation of thermogenic beige fat.

Tooth loss and radiographic bone loss in patients without regular supportive care: A retrospective study.

Background: Very few studies have investigated the effect of patient and site factors on periodontal progression and long-term tooth loss in populations with minimal dental care. The aim of this retrospective study was to assess tooth loss and radiographic bone loss over at least 5 years in patients attending a national-health service primary care practice in Sicily and undergoing no regular care.

Methods: Records of two hundred consecutive patients with at least 5 years follow-up were screened and demographic, clinical and radiographic data were retrieved.

Para-adrenal schwannoma mimicking a giant adrenal lesion.

A 57-year-old man was incidentally diagnosed with a 7 cm left-sided retroperitoneal mass. The mass was presumed to be arising from the left adrenal gland on a CT scan of the adrenal glands. Thus, a thorough workup ensued, looking into the possible functionality of the lesion.

Shades of white: new insights into tissue-resident leukocyte heterogeneity.

Populations of white blood cells (leukocytes) have been found in tissues and organs across the body, in states of both health and disease. The role leukocytes play within these tissues is often highly contested. For many leukocytes, there are studies outlining pro-inflammatory destructive functions, while other studies provide clear evidence of anti-inflammatory homeostatic activities of leukocytes within the same tissue.

A brown tumor secondary to hyperparathyroidism in the maxilla, skull, scapula, and femora.

Primary hyperparathyroidism presenting with diffuse skeletal involvement, such as discrete osteoclastic bone lesions, is rare. We describe a 35-year-old woman who presented with a left mandibular mass that rapidly enlarged over 3 weeks. Radiological, histological, and biochemical investigations led to the diagnosis of brown tumor secondary to primary hyperparathyroidism.
