Introduction We wanted to assess the efficacy, predictability, and stability of topography-guided, laser-assisted in situ keratomileusis (TGL) on normal untreated eyes with a preoperative best corrected visual acuity (BCVA) of 20/20. Methods This was a retrospective, non-randomized, and single arm study evaluating the outcomes of TGL in eyes with a preoperative BCVA of 20/20. We included 50 eyes of 50 patients who presented to the Hashmanis Hospital, Pakistan and were followed for six months postoperatively. All eyes underwent treatment using the Alcon Wavelight Allegro Topolyzer (Alcon Laboratories, Inc., TX, USA). Results The mean preoperative sphere, cylinder, and spherical equivalent (SE) values were -4.3 ± 1.6 dioptres (D), -1.0 ± 0.8 D, and -4.8 ± 1.8 D. On day one these values were 0.2 ± 0.8 D, -0.5 ± 0.3, and  0.3 ± 0.8, respectively, and on month six they were -0.1 ± 0.6, -0.5 ± 0.3, and -0.4 ± 0.6 D, respectively. On postoperative day one and month six, 86% and 94% of eyes had a UCVA of 20/20 or better, respectively. Two eyes (4%) had an SE change of greater than 0.5 D from three to six months. Conclusion Our study demonstrates good efficacy, predictability, and stability of eyes undergoing TGL with a follow-up of six months.

All-trans retinoic acid (ATRA) is a derivative of vitamin A and is the mainstay treatment of acute promyelocytic leukemia (APL). Hypercalcemia is a rare yet important side-effect of ATRA, especially when it is used concomitantly with a medication that impedes its metabolism by inhibiting cytochrome P-450 in the liver and thus increasing the duration of exposure to ATRA. Azole antifungal drugs such as voriconazole are frequently used in patients undergoing chemotherapy due to a high incidence of fungal infections. These medications inhibit two vital enzymes of cytochrome P-450, CYP2C9 and CYP3A4, potentiating the effects of ATRA on calcium metabolism. We present a case of a nine-year-old girl who underwent chemotherapy with all-trans retinoic acid for acute promyelocytic leukemia. The patient was given an anti-fungal cover with voriconazole for extensive fungal chest infection simultaneously. She was found to have asymptomatic hypercalcemia on routine follow-up during the consolidation phase. Both medications were stopped. Subsequently, she was admitted to the ward and managed conservatively with hydration. Serum calcium levels were returned to normal within six days after stopping the combination of ATRA and voriconazole. We underscore that the use of anti-fungal medications should be limited while using ATRA. However, strict monitoring must be done when a combination of these drugs is started, if necessary.

Background There is growing attention to the use of mHealth technologies to promote glycemic control for women with GDM around the world, but research on promoting a change in health behaviors is lacking. This study aimed to document the process of designing, developing, and testing the feasibility and acceptability of the SEESPA. Methods This single-arm pilot clinical trial study included 15 pregnant women with GDM. Following SEESPA development (e.g., goal setting and action plan, role modeling, motivational messages, mastery of experiences, and tracking healthy behaviors), all participants were provided access to use the SEESPA for 4 weeks. Feasibility outcomes assessed were rates of recruitment, retention rate, success rate of transmitting motivational text messages, rate of participants acknowledging receipt of text messages, and success rate of recording healthy behaviors. Acceptability outcomes were determined by asking open-ended questions through telephone interview at 4-week post-intervention. Results Fifteen randomly selected women consented to participate in the study, with a 60.0% ( n  = 9) retention rate at post-trial intervention and 40.0% ( n  = 6) trial dropout. Two motivational text messages per week were sent to all participants. Of these, 68.1% were acknowledged by the participants. Study participants reported that SEESPA is useful, effective, and they felt satisfied about it. In addition, they brought few suggestions that will be integrated on the final version of the app. Conclusions and Clinical Relevance. The developed innovative SEESPA is a feasible and acceptable intervention for behavioral modifications among women with GDM, and is ready to be tested in a larger RCT study which is expected to inform the health policymakers to integrate SEESPA with the antenatal health care practice of women with GDM, specifically in developing countries where there is a greater risk of developing GDM complications among mothers and their infants.

The 2019 coronavirus disease (COVID-19), declared a pandemic by the World Health Organization (WHO), is spreading worldwide rapidly.1 As of August 9, 2020, the total death toll had reached about 0.72 million with approximately 19.4 million confirmed cases worldwide.2 The WHO stated that “Our greatest concern is the potential for the virus to spread to countries with weaker health systems, and which are ill-prepared to deal with it.” [...]many people, including the general public and marketers in Pakistan, have panic-bought and hoarded these drugs, causing a shortage of these lifesaving medicines in the market. Preliminary evidence has reported that hydroxychloroquine shows antiviral activity in-vitro against coronaviruses, particularly in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).7 The adverse effects associated with the use of antimalarial drugs like retinopathy and neurotoxicity should not be undermined, particularly chloroquine, which tends to cause torsades de pointes associated with QT interval prolongation and has the potential to cause life-threatening ventricular tachyarrhythmia in cardiac patients.8 Preliminary results of a study in China found that methylprednisolone diminishes the mortality in patients with severe COVID-19; however, almost half of the patients died (23/50). [...]the use of methylprednisolone warrants further investigation.9 A systematic review of studies recommends the use of tocilizumab as a compassionate option on COVID-19 patients but also warns to perform latent tuberculosis testing during and before the therapy as it may reduce the antimicrobial activity of IL-6.10 For public safety concerns associated with self-medication, health authorities in Pakistan must use social media tracking tools and SMS services to dispel any kind of misinformation or disinformation regarding the misuse of aforementioned drugs.

HIV in Pakistan is concentrated to people who inject drugs (PWID) and easy accessibility of narcotics to this population cannot be disregarded as a risk factor of growing encumbrance of AIDS in the country. All the narcotics and other medications having high potential of abuse are stratified into Schedule G of Punjab Drug Rules 2017. According to these rules, drugs in Schedule G shall be sold in pharmacy under the direct supervision of qualified pharmacist. However, Schedule G is not implemented in Punjab due to continuous resistance from pharmaceutical stakeholders including medical store owners (who are barred to sell drugs from schedule G). Since 1.6 million PWID reported misuse of prescription opioids for non-medical use, delayed implementation of schedule G is attributing to the unabated sale of narcotics without prescription and for non-medical purposes, which is further contributing to the staggering number of PWID in the country. Implementing schedule G will not only curb the existing situation of HIV but will also mitigate the contribution of PWID towards the future events.
