This study seeks to assess the hydrogeochemical characteristics of groundwater in the southern part of Thal Desert of Pakistan. The primary focus lies in identifying potential sources of contamination and evaluating their impact on groundwater and the ecosystem. Groundwater samples were collected from diverse sources including shallow hand pumps, tubewells, and dug wells, with depths ranging from 11 to 28 m.

- Groundwater resources in Pakistan are facing depletion and quality issues due to over-extraction and urbanization, prompting a study of the hydrostratigraphical and hydraulic conditions in the Thal Doab region of Punjab.
- The study utilized electrical resistivity surveys and groundwater sample analysis to map the aquifers, revealing four to six geo-electric sublayers with varying resistivity indicative of different water quality levels.
- Results showed promising areas for fresh groundwater, while lower resistivity areas indicated marginally suitable or saline water, with additional assessments conducted to evaluate the water's suitability for drinking based on WHO guidelines.
Objectives: Sternal fractures occur after deceleration injuries such as falls and road traffic accidents. Recovery from isolated fractures is excellent, but mortality increases dramatically with concurrent chest injuries such as rib fractures and soft tissue injuries. Short-term complications include chest pain, which prevents patients from taking deep breaths and coughing, thereby predisposing them to chest infections.

Purpose: To determine aneurysm neck diameter change after endovascular repair (EVR) of abdominal aortic aneurysm (AAA) and its relationship to stent-graft diameter.
Materials And Methods: The cases of 73 patients with AAAs who underwent EVR were reviewed retrospectively: 68 had preoperative imaging available. Neck diameter was reviewed by a single observer (M.
