RESUMO
BACKGROUND Coronary stent dislodgement is rare but carries serious complications like thrombosis, myocardial infarction, disruption of the systemic circulation, and coronary dissection, which can lead to sudden death. Thus, rapid evaluation and intervention are needed to restore blood flow to vital organs. CASE REPORT A 46-year-old woman with no relevant past medical history except for smoking, presented to the Emergency Department (ED) with left-sided chest pain. The physical exam was unremarkable. EKG showed ST segment elevation, and troponin was 4.03. She underwent cardiac catheterization, which showed 100% occlusion of the left anterior descending coronary artery (LAD). A drug-eluting stent (DES) was placed. Later, she had chest pain similar to the initial episode. EKG showed 1-mm elevation at ST segment in leads V1 and V2 and T wave inversion in leads V2, V3, V4, and V5. She underwent a repeat heart catheterization, which revealed a dissection in the middle LAD distal to the initial stent placement. She was treated with another stent overlapping the proximal stent. While attempting to cross the proximal stent, the stent came off the balloon, slipped from the wire, and went down into the descending aorta. CONCLUSIONS Coronary artery stent dislodgement is a rare event that can lead to significant complications during PCI. Patient restlessness and small-sized, severely angulated, and previously stented coronary arteries are associated risk factors. The main treatment option is stent retrieval, either surgically or using other available techniques. If retrieval of the stent is impossible, crushing it against the blood vessel wall could be considered.

Objectives To evaluate the sociodemographic and clinical characteristics of patients presented with acute self-poisoning at a tertiary care hospital in Pakistan. Methods and Patients A comparative study was conducted at Lady Reading Hospital MTI between May 2018 to May 2019 for a duration of 12 months. All patients diagnosed with acute self-poisoning were included in the study. Patients with inconclusive diagnosis, who were dead prior to the arrival to the hospital, or had an incomplete history of poison exposure were excluded from the study. At the time of arrival to the emergency department, the patient was first stabilized. Patients were grouped into two according to the type of exposure, i.e., accidental self-poisoning and deliberate self-poisoning (DSP). Sociodemographic and clinical characteristics of patients were recorded in a preformed proforma. The data were analyzed using Statistical Package for the Social Sciences (SPSS) Version 26 (IBM Corp., Armonk, NY, USA). Results The mortality rate in patients with accidental poisoning was 9.62%, whereas it was 26.28% in DSP patients. Data were stratified according to the mode of poisoning, i.e., accidental vs DSP, and variables were assessed in patients who did not survive. It was found that 60% of patients who died in the accidental group were aged 0-15 years. In contrast, only one patient between aged 0-15 years died in the DSP group and the majority of the deaths occurred in those aged 25.1-35 years (31 [75.6%]). Conclusions In conclusion, women more often attempted suicide, whereas males suffered accidental poisoning more frequently. Firstly, we found a female predominance in the DSP group, whereas males were more prevalent in with young children experiencing accidental poisoning. Longer time from ingestion of poison to the arrival is associated with poor patient prognosis.
RESUMO
Introduction Despite the sunny climate, women in Pakistan are prone to vitamin D deficiency and subsequent low bone mineral density. The current study explores the extent of this deficiency in both pre- and postmenopausal women in our setting. Methodology A cross-sectional study was conducted at the outpatient departments of Lady Reading Hospital and Hayatabad Medical Complex Peshawar, Pakistan during the time period between March 2018 and June 2019. Hundred premenopausal women (control group) and 100 postmenopausal women (study group) were inducted in the study. Serum vitamin D levels were determined in patients with suspected vitamin D deficiency. Bone mineral density (BMD) was determined for each patient and the cost of each scan was afforded by our department. A dual-energy x-ray absorptiometry (DEXA) scan was used to perform the bone mineral density assessment. The data was analyzed using Statistical Package for Social Sciences (SPSS) version 26 (IBM, Chicago, IL). Results Serum 25OHD concentration in postmenopausal women was significantly lower compared to premenopausal women (p<0.001). In the study group, 36.0% of women had a severe deficiency of serum vitamin D levels, whereas, in the control group, only two women suffered from severe deficiency of vitamin D. Similarly, bone mineral density was also significantly correlated with the menopausal status of the women (p<0001). It was found that three-fifths of the postmenopausal women had a low bone density. Twenty-four percent of postmenopausal women had very low BMD. In comparison, only a single premenopausal woman was found to have a Z-score of below -2.0. Conclusion The current study highlights the impact of menopause on vitamin D levels and BMD. In our study, we found a significant difference between vitamin D levels and BMD in women of reproductive age compared to postmenopausal women.
