Background: Severe fever with thrombocytopenia syndrome virus (SFTSV) is a lethal threat.Increasing Severe fever with thrombocytopenia syndrome (SFTS) risk in Asia and the United States stems from the spread of natural host, Haemaphysalis longicornis. Rapid and accurate SFTSV molecular diagnosis is crucial for treatment decisions, reducing fatality risk. Methods: Blood samples from 17 suspected SFTS patients at Chuncheon Sacred Heart Hospital (September-December 2022) were collected. SFTSV was diagnosed using two reverse transcription-quantitative polymerase chain reaction (RT-qPCR) assays from Gangwon Institute of Health and Environment (RT-qPCR/GIHE) and Asan Medical Center (RT-qPCR/AMC). To address RT-qPCR disparities, amplicon-based MinION sequencing traced SFTSV genomic sequences in clinical samples. Results: In two samples (N39 and N50), SFTSV was detected in both RT-qPCR/GIHE and RTqPCR/AMC. Among 11 samples, RT-qPCR/AMC exclusively detected SFTSV. In four samples, both assays yielded negative results. Amplicon-based MinION sequencing enabled nearly whole-genome sequencing of SFTSV in samples N39 and N50. Among 11 discordant samples, five contained significant SFTSV reads, aligning with the RT-qPCR/AMC findings. However, another six samples showed insufficient viral reads in accordance with the negativity observed in RT-qPCR/GIHE. The phylogenetic pattern of SFTSV demonstrated N39 formed a genetic lineage with genotype A in all segments. SFTSV N50 grouped with the B-1 sub-genotype for L segment and B-2 sub-genotype for the M and S segments, indicating genetic reassortment. Conclusion The study demonstrates the robust sensitivity of amplicon-based MinION sequencing for the direct detection of SFTSV in clinical samples containing ultralow copies of viral genomes. Next-generation sequencing holds potential in resolving SFTSV diagnosis discrepancies, enhancing understanding of diagnostic capacity, and risk assessment for emerging SFTSV.

The role of a family physician in the management ofVibrio vulnificusinfection is multifaceted, encompassing prevention, early diagnosis, treatment, and education.Vibrio vulnificusis a Gram-negative, rod-shaped bacterium and an opportunistic human pathogen. Infection is common inV. vulnificusspecies and it can potentially cause a necrotizing fasciitis which is life threatening. Presented here is a case of a 39-year-old pregnant female who came in at the Emergency Department due to a noticeable swelling and severe pain on the third digit of her left hand after it was punctured while cleaning fresh Tilapia. The patient was then urgently referred to an orthopedic specialist for further management. Given the risk of compartment syndrome or necrotizing fasciitis the patient underwent amputation of the third digit of left hand. Patient underwent psychosocial and supportive intervention given by the family physician anticipating challenges in her illness trajectory. The paper emphasizes the role of family physicians in the comprehensive management ofVibrio vulnificusinfection, traversing all levels of prevention. Through educating patients and the community, along with providing timely and appropriate medical care, we can significantly reduce the morbidity and mortality associated with this serious infection.

Introduction: Opalski Syndrome is a rare type of stroke variant presenting with signs of lateral medullary syndrome plus ipsilateral hemiparesis. A confirmed myocardial infarction simultaneously occurring with this acute ischemic stroke syndrome makes this an even more challenging case of Cardiocerebral infarction. Case: The patient is a 48-year-old female, a known diabetic and asthmatic, and was seen due to a 3-day history of sudden onset of non-rotatory dizziness associated with diplopia, non-projectile vomiting, numbness of the left side of the face and lingual dysarthria. She was initially admitted in a primary hospital wherein she developed chest pain, dyspnea and diaphoresis. She was transferred and was received with findings of miosis of the left eye, rotational nystagmus, left dysmetria, decreased pain and temperature sensation on the right extremities, left central facial palsy, tongue deviation to the left side, left hemiparesis and upward Babinski on the left. We localize this lesion on the left lateral medullary area with involvement of the caudal left corticospinal tract. Hence, a clinical impression of Opalski Syndrome was made. This was confirmed with cranial MRI findings of T2/FLAIR hyperintense focus involving the left lateral aspect of the medulla. The patient’s Troponin I was also elevated and she was managed as a case of acute coronary syndrome - NSTEMI. Hence, a diagnosis of Type III Cardiocerebral infarction was made. Medical intervention was started with dual antiplatelet therapy and anticoagulation with noted clinical improvement. Conclusion This case report highlights the diagnosis of Opalski Syndrome in a patient also presenting with Cardiocerebral infarction. There should be prompt recognition of the following disease entities to have an effective treatment, avoid cardiac and neurologic sequelae, and achieve an overall favorable prognosis.
Lateral Medullary Syndrome

BACKGROUND

Remdesivir is an intravenously administered antiviral drug that inhibits RNA-dependent RNA polymerase. In vitro studies have shown that remdesivir can inhibit the growth of the COVID-19 virus in infected Vero cells and can inhibit infection in human cell lines.

To determine the efficacy and safety of remdesivir in treating patients with COVID-19 infection.

A systematic search of electronic medical literature databases was done from inception until September 4, 2022. Search for ongoing studies and preprints was also done. Risk of bias assessment was done using Cochrane risk of bias tool version 2.0. Measures of effect used were relative risk (RR) and 95% confidence interval (CI). Subgroup analysis by disease severity was preplanned. The estimates for efficacy and safety of remdesivir was calculated using Review Manager 5.4 software.

Nine randomized controlled trials with 13,085 participants were identified. Eight of the included studies recruited confirmed COVID-19 patients needing hospitalization, while one study limited recruitment to nonhospitalized patients. Remdesivir showed significant benefit for outpatients with mild to moderate disease with at least one risk factor for disease progression in terms of COVID 19-related hospitalization (RR 0.13 95% CI 0.03 to 0.59), all-cause hospitalization (RR 0.28, 95% CI 0.10 to 0.75), and need for medically-attended visits (RR 0.19, 95% CI 0.07 to 0.56). For hospitalized patients, remdesivir had a slight benefit in reducing all-cause mortality at day 28 (RR 0.90, 95% CI 0.83 to 0.98). Subgroup analysis by disease severity showed a trend towards reduction in mortality among those with severe disease (RR 0.61, 95% CI 0.35 to 1.07), with no effect on those with critical disease (RR 0.96, 95% CI 0.87 to 1.04), and inconclusive effect for those with mild-moderate disease (RR 0.74, 95% CI 0.49 to 1.11). Remdesivir showed benefit in decreasing clinical deterioration (RR 0.75, 95% CI 0.61 to 0.89), improving recovery rate (RR 1.07, 95% CI 1.01 to 1.13), and reducing the need for mechanical ventilation (RR 0.68, 95% CI 0.51 to 0.90). There was inconclusive effect on the need for ICU admission (RR 0.98, 95% CI 0.43 to 2.22). No increased risk of adverse events (RR 0.98, 95% CI 0.91 to 1.06), including serious adverse events (RR 0.77, 95% CI 0.57 to 1.03), was seen.

Based on the available evidence, remdesivir shows benefit in the treatment for patients with mild, moderate, and severe COVID-19 infection. However, there was no benefit in mortality noted among those with critical disease requiring mechanical ventilation. Remdesivir demonstrated a good safety profile, with no increased risk of adverse events compared to control. These results are consistent with the international agencies’ recommendations for the use of remdesivir among patients with mild, moderate or severe COVID-19 infection, but not for those with critical infection.

Current evidence supports the use of remdesivir as treatment for selected patients with COVID-19.

Introduction: The industrial park in the district of Parit Raja, Batu Pahat resulted in rapid growth of the town during the last 20 years and has been a reason of concern that this park also has contributed greatly to the problem of air pollution. The aim of this study was to evaluate the association between industrial air pollution and respiratory symptoms in adults living in the Parit Raja. Methods: A comparative cross-sectional study was undertaken among residents in the district of Parit Raja, Batu Pahat, Johor, Malaysia. A total of 110 residents aged between 19 and 65 years were randomly selected and information on personal characteristics and respiratory symptoms was obtained through a validated questionnaire. The prevalence of respiratory symptoms was compared between residents recruited from the areas situated about 5km radius of the industrial park (exposed) and >5km radius from the industrial park (comparative). Results: A total of 34.5% and 25.5% of adults from the exposed group reported experiencing coughing for the last 3 months and chest tightness for the last 3 years. The logistic regression models showed that symptoms of coughing was associated with the exposed group (aOR=6.34, 95% CI=2.08-19.35), male respondents (aOR=3.18, 95% CI=1.10-9.16) and who stay in Part Raja for more than 14 years (aOR=3.16, 95% CI=1.14-8.79). Conclusion: This study demonstrated that long-term air pollution exposures are consistently associated with respiratory symptoms in residents living in the proximity of industrial parks. Therefore, public health initiatives that aim to provide more conducive environment are needed, especially for residents living near industrial parks.

Introduction: Malaysian adults consume excessive amounts of salt daily, which could lead to hypertension. Understanding knowledge, attitudes, and practices (KAP) surrounding salt intake is crucial for designing effective interventions to reduce excessive consumption and its associated health risks. Therefore, this study aimed to adapt an existing salt intake-related KAP questionnaire that was previously employed in a local population-based survey and to validate and test its reliability. Methods: This cross-sectional study comprised two phases: (1) adaptation, content validation (CV), and face validation (FV); (2) pilot testing and reliability testing. CV and FV involved a total of seven experts and ten Malaysian adults from the Klang Valley, respectively. Pilot testing involved 139 Malaysian adults to determine the questionnaire’s reliability. Content validity index (CVI) and Face validity index (FVI) values were calculated to analyse CV and FV. Reliability of each domain was analysed by obtaining Cronbach’s alpha (α) values. Results: A self-administered questionnaire comprising six items each for knowledge, attitude, and practice was developed. The questionnaire demonstrated acceptable item-level CVI (I-CVI) and item-level FVI (I-FVI) values of at least 0.83, indicating that the items were relevant, clear, non-ambiguous, and simple. Reliability test showed acceptable α values of at least 0.70 for each domain, suggesting that the questionnaire was reliable. Conclusion: This tool could be considered valid and reliable for assessing the level of KAP towards salt intake among adults in Malaysia.

Acquired perforating collagenosis (APC) is a rare dermatological condition characterized by the spontaneous eruption of skin-colored or erythematous papules or nodules that eventually ulcerate and exude collagenous material. The exact etiology of APC remains unclear, although various triggers, including infections, medications, autoimmune diseases, and trauma, have been implicated.

This case report presents a 63-year-old female with a history of diabetes who developed erythematous papules and plaques topped with thick, yellowish, hyperkeratotic, adherent crusts on the upper back following an insect bite. Histopathological examination confirmed the diagnosis of APC, characterized by a cup-shaped invagination in the epidermis containing degenerated collagen bundles and basophilic material. Masson-trichrome staining showed transepidermal elimination of the collagen fibers. Patient was initially prescribed tretinoin 0.1% cream to be applied 2x a day. However, patient was not able to apply prescribed medications. Interestingly, without any specific treatment, the patient’s symptoms gradually improved over 3 months and eventually resolved completely.

This case report highlights the spontaneous resolution of APC in a patient following an insect bite. While most cases of APC require medical intervention, this case demonstrates the potential for spontaneous healing in certain individuals. Further research is needed to understand the factors that influence the course of APC and to identify potential predictors of spontaneous resolution.
