Actinomyces-infected bronchopulmonary sequestration: An uncommon pathogen in a rare anomaly.

Bronchopulmonary sequestration, a rare congenital anomaly, involves a nonfunctioning lung tissue mass supplied by anomalous vessels. It is rarely infected by Actinomyces, further complicating the clinical presentation, with limited reported cases. This case highlights the distinctive clinical aspects, diagnostic challenges, and successful management strategies of such a rare clinical entity.

Heated tobacco product (IQOS) induced pulmonary infiltrates.

Background: Heated tobacco products (HTPs) have been marketed as safer alternatives to conventional cigarettes, but emerging evidence suggests potential respiratory risks. We present a case of pulmonary complications associated with IQOS, a popular HTP, contributing to the growing understanding of these risks.

Case Description: A 40-year-old chronic smoker switched to IQOS, consuming 1.

Etiology, diagnostic modalities, and short-term outcomes of hemoptysis-a retrospective cross-sectional study from a tertiary care center in Qatar.

Background: Hemoptysis is a concerning symptom characterized by the expectoration of blood from the respiratory tract, which can range from mild to life-threatening. It can be caused by various underlying conditions. Accurate diagnosis is critical for effective management.

Nitrofurantoin-Induced Lung Injury: A Reminder of an Overlooked Threat.

Nitrofurantoin is a commonly prescribed antibiotic for urinary tract infection (UTI) treatment and prophylaxis. Although relatively rare, nitrofurantoin can cause a spectrum of lung injuries, from acute hypersensitivity reactions that might be fatal to chronic reactions involving fibrosis. Therefore, treating physicians' awareness and regular monitoring is essential for early recognition, drug withdrawal, avoiding unnecessary treatment, and preventing irreversible fibrosis.

Primary intrapulmonary thymoma a case report.

Primary intrapulmonary thymoma (PIT), defined as the presence of thymoma tissue in the lung without an accompanying mediastinal component, is uncommon and so offers a diagnostic quandary. We describe the case of PIT in an 81-year-old man.

Perioperative Hypertensive Response In A Patient With Implanted Deep Brain Stimulation Device: A Case Report.

This case report features unique anaesthetic management of a patient with implanted deep brain stimulation (DBS) device undergoing abdominal surgery. It features the intraoperative measures taken for this patient for the implanted DBS. After turning off the DBS preoperatively, the patient showed an exaggerated sympathetic response which was very much resistant to medicines.

An attention-based recurrent learning model for short-term travel time prediction.

With the advent of Big Data technology and the Internet of Things, Intelligent Transportation Systems (ITS) have become inevitable for future transportation networks. Travel time prediction (TTP) is an essential part of ITS and plays a pivotal role in congestion avoidance and route planning. The novel data sources such as smartphones and in-vehicle navigation applications allow traffic conditions in smart cities to be analyzed and forecast more reliably than ever.

Foreign body aspiration in an adult: An endobronchial "Melon-oma".

Foreign body (FB) aspirations in adults are relatively uncommon. The most commonly aspirated FBs in adults are organic, especially vegetable matter, peanuts, and fragments of bones. We report a rare case of a FB discovered in the left main bronchus of an adult male admitted to the intensive care unit.

Pre-procedural SARS-CoV-2 PCR testing in the pulmonary function laboratory at a tertiary government hospital in Qatar: A clinical audit.

Background: Prior to pulmonary function testing (PFT), local and international recommendations advise pre-procedural screening. Pulmonary function tests generate aerosol droplets containing millions of viruses, significantly increasing the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission not only to the individuals in and around the PFT office, but also to subsequent patients who undergo the test later in the same room.

Methods: This clinical audit was carried out to establish the rate of positive pre-procedural SARS-CoV-2 PCR testing before a PFT.

Functionally graded additive manufacturing for orthopedic applications.

Background: Additive Manufacturing due to its benefits in developing parts with complex geometries and shapes, has evolved as an alternate manufacturing process to develop implants with desired properties. The structure of human bones being anisotropic in nature is biologically functionally graded i,e. The structure possesses different properties in different directions.

Nanostructured Coatings: Review on Processing Techniques, Corrosion Behaviour and Tribological Performance.

Corrosion and tribology are surface phenomena. Modifying surfaces of materials without resorting to altering their bulk properties is an effective route to alleviate corrosion, friction and wear, encountered in engineering applications. With the advancements in the field of nanotechnology, surface protective coatings with nanomaterials can be readily developed to explore their functionality in mitigating chemical/physical damage of surfaces.

Anaesthetic Challenges in a Paediatric Patient with Escobar Syndrome-Difficult Airway and Postoperative Pneumothorax.

Escobar syndrome (ES) is an autosomal recessive disorder characterised by the presence of pterygia in cervical, antecubital and popliteal regions. Anaesthesiologist encounter notable challenges in this syndrome, especially airway management due to associated malformations like cleft lip/palate, micrognathia, syngnathia, ankyloglossia, neck contracture, cervical spine fusion, limited neck extension and craniofacial dysmorphism. In addition to difficult airway, anaesthesiologist may encounter other perioperative challenges.

Modeling-framework for model-based software engineering of complex Internet of things systems.

Internet of things (IoT) systems are composed of variety of units from different domains. While developing a complete IoT system, different professionals from different domains may have to work in collaboration. In this paper we provide a framework which allows using discrete and continuous time modeling and simulation approaches in combination for IoT systems.

Challenges in the diagnosis of pulmonary mucormycosis in a diabetic with a review of literature.

Diabetes Mellitus appears to be the most common underlying condition associated with mucormycosis; a rare opportunistic fungal infection associated with high morbidity and mortality. Pulmonary mucormycosis may mimic pneumonia and thus pose challenges in achieving a timely diagnosis critical to successful outcomes. We present a case of a 65-year-old diabetic who presented with fever and haemoptysis that was managed as pneumonia.

Isolated pulmonary cryptococcosis in a patient with Crohn's disease treated with infliximab: A case report and literature review.

Tumor necrosis factor-alpha (TNF-α) inhibitors are widely used to treat various inflammatory conditions, where they have demonstrated excellent efficacy and tolerability. However, increased risk of infections is one of the most important concerns associated with these agents. Reactivation of tuberculosis and fungal infections have emerged as significant infective complications of anti-TNF-α therapy.

Nanodiamond Particles as Secondary Additive for Polyalphaolefin Oil Lubrication of Steel-Aluminium Contact.

Nanodiamond (ND) particles are effective lubricant additives. Attention of research has shifted towards investigating the particles as secondary additives. ND particles provide more benefits as secondary additives than as the sole lubricant additive for steel-steel contacts.
