Case 323: Minute Pulmonary Meningothelial-like Nodules.

A 70-year-old woman with a 6-year history of asthma, a 12-year history of diabetes mellitus, and who did not smoke presented to the pulmonology clinic with dyspnea and cough. Chest CT performed 5 years earlier for similar symptoms revealed multiple pulmonary nodules. However, she was lost to follow-up before the work-up was concluded.

Case 323.

A 70-year-old woman with a 6-year history of asthma, a 12-year history of diabetes mellitus, and who did not smoke presented to the pulmonology clinic with dyspnea and cough. Chest CT performed 5 years earlier for similar symptoms revealed multiple pulmonary nodules (Fig 1). However, she was lost to follow-up before the work-up was concluded.

Evaluation of hypermetabolic mediastinal-hilar lymph nodes determined by PET/CT with EBUS-TBNA and calculation of SUVmax cutoff values in differentiation of malignancy.

Computed tomography (CT) and positron emission tomography (PET) are the most commonly used methods for diagnosis and staging in both malignant and benign diseases of the lung parenchyma and mediastinum. Endobronchial ultrasonography (EBUS) guided transbronchial needle aspiration biopsy (TBNA) has become widespread in recent years because it allows minimally invasive tissue sampling. PET-CT has high sensitivity in the diagnosis of malignancy but has low specificity.

Can PET/CT be used more effectively in pleural effusion evaluation?

Purpose: Sometimes, characterization of pleural effusion (PE) can be challenging especially in patients whom invasive procedures/recurrent invasive procedures cannot be performed. The main purpose of the study is to answer this question, Can F-FDG-PET/CT contribute to reduction in the number of invasive procedures or patients undergoing to invasive procedures? Results may increase the effectiveness of patient management by facilitating clinical decision-making, especially in patients who cannot undergo invasive/recurrent invasive procedures.

Methods: Sixty-seven patients' F-FDG-PET/CT, pleural fluid cytologies (PFCs) and, if any, pleural biopsies were re-assessed.

Evaluation of the Efficacy of Sildenafil Citrate Following Severe Head Trauma in an Experimental Rat Model.

Aim: To investigate the acute effects of sildenafil citrate in an experimental model of severe head trauma, and to compare it with the efficacy of mannitol, which is an osmotically active agent frequently used in clinical treatment of traumatic brain injury (TBI).

Material And Methods: Twenty-eight Wistar-derived albino strain female rats were randomized into four groups comprising seven rats each. These groups were designated as follows: Group I: sham; Group II: TBI; Group III: TBI + mannitol (20% 1 gr/ kg, intraperitoneal); and Group IV: TBI + sildenafil citrate (10 mg/kg, intraperitoneal).

Tumor deposits in salivary gland tumors.

Tumor deposits (TDs), identified in different types of carcinomas are associated with poor prognosis. Salivary gland tumors were evaluated for the first time for TDs in this series. Pathological and clinical features of 25 salivary gland carcinomas primarily treated surgically including neck dissection were determined and all cases were evaluated for TDs in dissection specimens.
