Papillary thyroid carcinoma from a thyroglossal cyst: case series.

Papillary carcinoma originating from a thyroglossal cyst represents an infrequent finding, which occurs in ~1% of cases of thyroglossal cyst and its presentation is usually the same as that of a benign cyst, which represents the most frequent benign congenital lesion of the neck. The diagnosis is usually presented as a finding on the histopathological examination. Two cases of a thyroglossal cyst with later development of malignancy are presented.

Evolution of clinical, histological and serological features in a Primary Sjὄgren´s Syndrome cohort and the limitations of the current classification criteria.

Objective: The classification and/or diagnosis of Primary Sjögren's Syndrome (PSS) requires a multidimensional approach. Although age and the duration of sicca symptoms can affect the clinical, serological and histological features found at initial evaluation, these are not considered when using classification criteria as a guide for PSS diagnosis. Our study aimed to explore if there is any relationship between the duration of symptoms and clinical, histopathological and serological findings.

Beta-2 Microglobulin in Whole Unstimulated Saliva Can Effectively Distinguish Between Sjögren's Syndrome and Non-Autoimmune Sicca Symptoms.

Objectives: This study aims to describe salivary beta-2 microglobulin (sB2M) levels in our setting and to assess the performance of sB2M for the diagnosis of Sjögren's syndrome (SS).

Patients And Methods: This cross-sectional, comparative study included 192 SS patients (2 males, 190 females; mean age 53.1 years; range 23 to 84 years) and 64 healthy controls (1 male, 63 females; mean age 46.

[Sjögren's syndrome (SS), a review of the subject and saliva as a diagnostic method].

Sjögren's syndrome is a chronic autoimmune disease whose main clinical manifestation is oral dryness (xerostomia) and ocular dryness (xerophthalmia). It is characterized by progressive mononuclear infiltration of the exocrine glands and can affect a variety of organ systems. The prevalence of primary Sjögren's syndrome varies from 0.

Warthin-Like Papillary Thyroid Carcinoma Associated with Lymphadenopathy and Hashimoto's Thyroiditis.

Defining the histologic variant of thyroid carcinoma is an important clinical implication as their progression, recurrence, aggressiveness, and prognosis differ. Warthin-like variant is one of the rarest histologic variants of papillary thyroid cancer. A 36-year-old female sought consult for assessment of a painless right neck tumor.

CD206+ cell number differentiates influenza A (H1N1)pdm09 from seasonal influenza A virus in fatal cases.

In 2009, a new influenza A (H1N1) virus affected many persons around the world. There is an urgent need for finding biomarkers to distinguish between influenza A (H1N1)pdm09 and seasonal influenza virus. We investigated these possible biomarkers in the lung of fatal cases of confirmed influenza A (H1N1)pdm09.
