The dawn of globalization has produced the need for doctors who are prepared to facilitate communities regardless of their ethical constraints. Medical ethics is an integral component of undergraduate training and has gradually affirmed that different ethical issues are encountered by doctors within rural settings and urban areas. There is a strong need to acknowledge that ethics varies as we move not only from urban or rural settings, but also as we move across different regions, countries, and continents. There have been various studies conducted in different regions of the world to highlight the presence of different ethical issues arising in various settings. This review aims to highlight common ethical issues faced by general practitioners in rural settings as various regions have different customs which influence their decision-making skills and the patients’ relationship with their practitioner. This gives rise to the necessary task of providing training for doctors so that they are better equipped to handle these challenging scenarios in primary health care domains in order to facilitate optimal health care for patients from diverse backgrounds in different settings ethically and professionally.

Fibroadenomas (FAs) are the most common benign tumors of the breast in young females. Most of the time, it presents as a well-circumscribed, painless, firm to hard, mobile, and slow-growing unilateral or bilateral breast lump. The median age of its presentation is 25 years with rare occurrence after menopause. The exact etiology of FA is still unclear. Unopposed estrogen in the growing breasts of young females is considered as a main factor in its pathogenesis. Family history and development of FA in identical twins are suggestive of genetic contribution to the pathogenesis of these tumors.

This is a case report of young twin sisters who presented at a tertiary care hospital in Lahore with a complaint of a synchronously developed unilateral breast lump. Fine needle aspiration cytology was planned after taking a detailed history and clinical examination of both patients. Diagnosis of FA was confirmed radiologically and through cytological examination. To the best of the authors’ knowledge, this is the first case of its kind reported from Pakistan.

ABSTRACT

Background and Objective: Statins can induce myopathy; however, the impact on muscle regeneration remains unclear. β2-agonists may mitigate statin myotoxicity. This study investigated the effects of simvastatin and formoterol on skeletal muscle regeneration and injury using a rat model.
Methods: Adult Sprague-Dawley rats (n = 90) were divided into three groups: control (A), simvastatin treatment (B), and simvastatin plus formoterol treatment (C). The rats were kept at room temperature for 3 months where an animal house diet was available ad libitum. Simvastatin was administered orally once a day, by oral gavage for 12 weeks; formoterol was concurrently administered to one group. Extensor digitorum longus muscles were analyzed for the myogenic differentiation factor (MyoD) by immunohistochemistry. Serum lactate dehydrogenase (LDH) levels were quantified as a marker of muscle damage.
Results: MyoD-positive myonuclei were significantly increased in the C group (simvastatin plus formoterol group) compared to the A and B Groups (control and simvastatin-only groups) (p < 0.05). Serum LDH levels were significantly lower in group C than in groups A and B (p < 0.05).
Conclusion: Formoterol alleviates statin-associated muscle injury in a rat model as evidenced by increased MyoD expression and decreased LDH levels. The activation of dormant satellite cells and increased expression of MyoD indicate the potential of formoterol to promote muscle regeneration.

ABSTRACT

Background and Objective: Replacing lost dentin with an appropriate substitute has been challenging in recent years. Biodentine and conventional glass ionomers are used as dentin replacement materials. This study aimed to compare the Vickers microhardness (VHN), diametral tensile strength (DTS), and setting time of Biodentine and glass ionomer cement (GIC).
Methods: This experimental study was conducted in the Department of Science of Dental Materials at Fatima Memorial College of Dentistry, Lahore, in collaboration with the Interdisciplinary Research Centre of Biomedical Materials, COMSATS Lahore from December 2022 to March 2023. A total of fifty disc-shaped samples (4 × 2 mm) of Biodentine and GIC Gold Label 2 were fabricated to assess the VHN, DTS, and setting time after immersion in distilled water for 1 hour and after 3 days. Data were analyzed by applying the paired and independent t-tests using Statistical Package for Social Sciences 26.0.
Results: The mean VHN value of Biodentine and GIC Gold Label 2 cement was 23.4 ± 1.5 and 17.5 ± 1.27 after 1 hour and 31.9 ± 1.66 and 29.6 ± 1.58 after 3 days, respectively. DTS of Biodentine [7.0 ± 0.91 mega pascal (MPa)] was significantly greater than GIC Gold label 2 (5.5 ± 0.68 MPa) after 1 hour (p < 0.05). However, after 3 days, there was a slight increase in the DTS of Biodentine (9.3 ± 1.53 MPa) while compared to GIC Gold label 2 (8.2 ± 1.0 MPa) and this difference was not statistically significant (p > 0.05). Biodentine had a higher setting time than GIC Gold label 2, with an initial setting time of 6.7 minutes compared to 2.9 minutes.
Conclusion: GIC Gold label 2 has a shorter setting time than the but Biodentine which, however, showed higher Vicker’s microhardness and DTS. Therefore, Biodentine may be a more suitable substitute for dentine replacement than the GIC Gold label 2.

Background and objective: Severely ill patients are at a higher risk of carrying nosocomial infections especially when admitted to the intensive care units (ICUs). Therefore, it is the professional obligation of all health workers to adhere to the scientifically accepted criteria for infection control in clinical settings. This study was conducted to assess intensive care nurses’ adherence to standard precautions (SPs) and to assess the practices of SPs in intensive care.

Methods: This cross-sectional study was carried out at ICUs of two public sector hospitals in Lahore, Pakistan, from March to September, 2022. A total of 150 nurses were selected for the study who worked in the medical-surgical, general, and specialized ICUs. The extent to which the behavior of a worker coincides with the prescribed standard (Adherence) and performing work repeatedly till it becomes a routine competency (Practice) was assessed using a structured questionnaire. The chi-square test was used to determine the link between adherence to SPs and the practice carried out by nurses. Data were analyzed and a p-value ≤ 0.05 was taken as significant.

Results: A total of 84.7% of nurses showed adherence while practice was demonstrated by 52.7% of nurses. No significant correlation (p-value:0.95) was however found between the practice and adherence to the SPs, despite the fact that a notable gap was observed between the practice and adherence to SPs among ICU nurses.

Conclusion: It is concluded that a compromised adherence to SPs of infection control in ICUs of public sector hospitals in Lahore is exhibited by the nurses.

ABSTRACT

Background and Objective: Root canal treatment is hampered by the presence of resilient bacteria within the canals of teeth which leads to the need for incorporation of intra-canal medication. This study aimed to assess the effectiveness of mustard gel against the highly resistant Enterococcus faecalis (E. faecalis) bacteria in comparison with calcium hydroxide (Ca(OH)2) paste as an intra-canal medicament.

Methods: This experimental study comprised forty extracted single-rooted teeth which were equally divided into two groups. In group 1, Ca(OH)2 paste was applied whereas in group 2, mustard gel was used. After disinfection, each tooth was sectioned horizontally into three equal parts. The standardized middle section was inoculated with a controlled strain of E. faecalis followed by the application of intra-canal medicaments for a week in both groups. The bacterial colonies were counted as colony-forming units (CFU/ml). Data were entered and analyzed by using Statistical Package for Social Sciences version 25.0.

Results: Microscopically, E. faecalis appeared as cocci-round shaped in chains or pairs. The median bacterial count was 1,550 (775-2,500) for group 1 (Ca(OH)2 paste) as compared to only 400 (200-775) in group 2 (mustard gel) (p < 0.001).

Conclusion: Mustard gel can be used as a cost-effective, readily available, and safe herbal alternative to Ca(OH)2 paste for root canal treatments.
