Aspergilloma Coexisting With Idiopathic Pulmonary Fibrosis: A Rare Clinical Entity.

Aspergilloma also known as fungal ball or mycetoma, is a saprophytic mycotic infection caused by species which usually colonizes pre-existing cavitary or cystic lesions in the lung. Here, we have a rare case of idiopathic pulmonary fibrosis (IPF) with bilateral bronchiectasis complicated by aspergilloma. Although the existence of aspergilloma is common in pre-existing lung cavities, its coexistence in patients with IPF is a rarity, and the incidence of such cases in the literature remains sparse.

Microstructural evolution during short heat treatment of constrained groove pressed Cu-5%Zn alloy.

Severe plastic deformation (SPD) is a widely used technique to obtain superior material properties specially mechanical properties. Constrained groove pressing (CGP) is found to be the most attractive SPD technique for the deformation of sheets and plates. However, this technique results in microstructural inhomogeneity during processing.

Efficacy of Exclusive Lingual Nerve Block versus Conventional Inferior Alveolar Nerve Block in Achieving Lingual Soft-tissue Anesthesia.

Objective: The aim of this randomized clinical trial was to assess the efficacy of exclusive lingual nerve block (LNB) in achieving selective lingual soft-tissue anesthesia in comparison with conventional inferior alveolar nerve block (IANB).

Materials And Methods: A total of 200 patients indicated for the extraction of lower premolars were recruited for the study. The samples were allocated by randomization into control and study groups.

A study of salivary opiorphin levels using different anesthetic drugs and techniques - A randomized controlled clinical study.

Purpose: This study aimed at assessing the change in salivary opiorphin levels before and after administration of local anesthesia, with the use of three different local anesthetic agents, and different anaesthetic techniques.

Methods: The investigators implemented a randomized controlled clinical study in 144 patients who required tooth extraction after administration of local anaesthesia. A total of 288 samples were collected in sterile containers before and after administration of local anesthetics.
