introduction: actinomycosis is a systemic chronic bacterial infection caused by actinomyces israelii, an anaerobic organism normally resident in the human mouth. however, the actinomycosis of the larynx is very rare, and only about 15 cases have been reported in the literature so far. most of the cases reported occurred in patients who had previously undergone radiotherapy for laryngeal cancer....

introduction: a thyroid nodule is a palpable swelling in a thyroid gland with an otherwise normal appearance. palpable thyroid nodules occur in 4 to 7 percent of the population. nodular thyroid diseases are more frequent in women than in men. most actions of thyroid hormone are mediated by the active form of thyroid hormone. d2 is essential for formation of active hormone of t3 through deiodina...

abstract bronchoalveolar carcinoma presenting as non-resolving consolidation is an uncommon presentation. the typical presentation of bronchoalveolar carcinoma is asymptomatic (solitary nodule) and remains without symptoms even as disease disseminates. we report a case of bronchoalveolar carcinoma presenting as non-resolving consolidation in a young male with productive cough, exertional breath...

introduction acute lymphoblastic leukemia (all) is the most common malignancy of childhood. patients with all commonly present with easy bruising and infections due to medullary involvement. the extra medullary involvements of all manifests as hepatosplenomegaly, lymphadenopathy, and testicular enlargement. among extramedullary manifestations of the all, thyroid involvement is rare. herein, we ...

background transient hypocalcemia is one of the postoperative complications of thyroidectomy for thyroid nodules, and intraoperative and postoperative intact parathyroid hormone (ipth) assays are used to predict postoperative hypocalcemia. objectives the current study was conducted to evaluate a single serum ipth measurement on postoperative day 1 (pod 1) as a means to predict hypocalcemia occu...

Legume root nodules are induced by N-fixing rhizobium bacteria that are hosted in an intracellular manner. These nodules are formed by reprogramming differentiated root cells. The model legumeMedicago truncatula forms indeterminate nodules with a meristem at their apex. This organ grows by the activity of the meristem that adds cells to the different nodule tissues. In Medicago sativa it has be...

Preneoplastic mammary nodule outgrowth lines were examined for their ability to grow and produce tumors in ovariectomized BALB/c mice. In addition, these nodule outgrowth lines and tumors derived from them were investigated for cytoplasmic estrogen receptor proteins by qualitative and quantitative techniques. Early ovariectomy, performed within 4 weeks after transplantation, slightly delayed bu...

Background: Clinically solitary thyroid nodule may be defined as a goitre which on clinical examination appears to be a single nodule in an otherwise normal gland. In reality, solitary thyroid nodule is not a single disease process but a constellation of processes encountered in a variety of clinical diseases such as dominant nodule of a multi nodular goitre, true adenoma, malignancy, thyroidit...

Detection of malignant lung nodules in chest radiographs is currently performed by pulmonary radiologists, potentially with the aid of CAD systems. Recent advancements in convolutional neural network (CNN) models have improved image classification and detection for many tasks, but there has been little exploration of their use for nodule detection in chest radiographs. In this paper we explore ...
