The essential occupation of well-digger includes wells drilling and maintenance in order to provide water. He comes in contact with various minerals, especially silica, whose particles unquestionably are a contributing factor to pulmonary diseases known as silicosis. Our study aims to highlight the epidemiological, clinical, radiological and evolutionary features of well-diggers with silicosis. We conducted a retrospective study of 54 well-diggers with silicosis whose data were collected in the Department of Respiratory Diseases at the University Hospital Ibn Rushd of Casablanca from March 1997 to January 2016. All patients were male well-diggers with an average age of 50 years. Smoking was found in 36 cases and a personal history of tuberculosis was observed in eight cases. Chest x-ray showed large opacities in 39 cases, small opacities in 15 cases and septat thickening in 11 cases. Silicosis was complicated by bacterial infection in 37% of cases, by pneumothorax in 4% of cases and by tuberculosis in 20% of cases. Therapeutic approach was established based on these complications. A declaration of occupational disease and compensation was made. Outcome was good in 12 cases, stationary in 17 cases and poor in 16 cases. Silicosis is a common pneumoconiosis among well-diggers. It affects lung function. We here highlight its frequent association with tuberculosis and emphasize on prevention which is the best treatment.

Nursing Practices for Preventing Delirium in Patients with Cancer with Prognoses of Months and Weeks: A Multi-Site Cross-Sectional Study in Japan.
Am J Hosp Palliat Care

Graduate School of Medicine, Mie University, Tsu, Japan.
Background: Delirium is a condition characterized by an acute and transient disturbance in attention, cognition, and consciousness. It is increasingly prevalent at the end of life in patients with cancer. While non-pharmacological nursing interventions are essential for delirium prevention, their effectiveness in terminally ill patients with cancer remains unclear.

Objective: Intraventricular baclofen (IVB) administration is used for the treatment of secondary dystonia associated with cerebral palsy (CP), but it has not been reported as a first-line infusion technique for spasticity. In this study, the authors report outcomes of patients with mixed or isolated spasticity treated with IVB administration.
Methods: A retrospective analysis was performed of consecutive patients treated with IVB between 2019 and 2023.
Phase Diagram, d-Wave Superconductivity, and Pseudogap of the t-t^{'}-J Model at Finite Temperature.

Recently, robust d-wave superconductive (SC) order has been unveiled in the ground state of the 2D t-t^{'}-J model-with both nearest-neighbor (t) and next-nearest-neighbor (t^{'}) hoppings-by density matrix renormalization group studies. However, there is currently a debate on whether the d-wave SC holds up strong on both t^{'}/t>0 and t^{'}/t<0 cases for the t-t^{'}-J model, which correspond to the electron- and hole-doped sides of the cuprate phase diagram, respectively. Here, we exploit state-of-the-art thermal tensor network approach to accurately obtain the phase diagram of the t-t^{'}-J model on cylinders with widths up to W=6 and down to low temperature as T/J≃0.

Objectives: To examine factors impacting diagnostic evaluation of suspected deep vein thrombosis (DVT) by analyzing the test ordering patterns and provider decision-making within a universal health coverage system in Hungary.
Methods: We analyzed test orders for suspected DVT between 2007 and 2020, and the financial framework influencing diagnostic practices. An anonymous survey was also conducted among Emergency Department physicians to explore factors influencing diagnostic decision-making.
Thalamic stereo-electroencephalography exploration in pediatric drug-resistant epilepsy: implantation technique and complications.
J Neurosurg Pediatr
January 2025
2Neurology, UT Southwestern, Dallas, Texas.
Objective: Patients with drug-resistant epilepsy (DRE) are often referred for phase II evaluation with stereo-electroencephalography (SEEG) to identify a seizure onset zone for guiding definitive treatment. For patients without a focal seizure onset zone, neuromodulation targeting the thalamic nuclei-specifically the centromedian nucleus, anterior nucleus of the thalamus, and pulvinar nucleus-may be considered. Currently, thalamic nuclei selection is based mainly on the location of seizure onset, without a detailed evaluation of their network involvement.
