PMID: 36256521 DOI: 10.1002/ptr.7649

Piper longum (family Piperaceae), commonly known as "long-pepper" or "Pippali" grows as a perennial shrub or as an herbaceous vine. It is native to the Indo-Malaya region and widely distributed in the tropical and subtropical world including the Indian subcontinent, Sri Lanka, Middle-East, and America. The fruits are mostly used as culinary spice and preservatives and are also a potent remedy in various traditional medicinal systems against bronchitis, cough, cold, snakebite, and scorpion-sting and are also used as a contraceptive. Various bioactive-phytochemicals including alkaloids, flavonoids, esters, and steroids were identified from the plant extracts and essential oils from the roots and fruits were reported as antimicrobial, antiparasitic, anthelminthic, mosquito-larvicidal, antiinflammatory, analgesic, antioxidant, anticancer, neuro-pharmacological, antihyperglycaemic, hepato-protective, antihyperlipidaemic, antiangiogenic, immunomodulatory, antiarthritic, antiulcer, antiasthmatic, cardioprotective, and anti-snake-venom agents. Many of its pharmacological properties were attributed to its antioxidative and antiinflammatory effects and its ability to modulate a number of signalling pathways and enzymes. This review comprehensively encompasses information on habit, distribution, ethnobotany, phytochemistry, and pharmacology of P. longum in relation to its medicinal importance and health benefits to validate the traditional claims supported by specific scientific experiments. In addition, it also discusses the safety and toxicity studies, application of green synthesis and nanotechnology as well as clinical trials performed with the plant also elucidating research gaps and future perspectives of its multifaceted uses.

Fulltext Organising pneumonia manifesting as a late-phase complication of COVID-19

Ng BH, Ban AY, Nik Abeed NN, Faisal M

BMJ Case Rep, 2021 Oct 29;14(10).
PMID: 34716149 DOI: 10.1136/bcr-2021-246119

Acute COVID-19 usually lasts 4 weeks from the onset of symptoms. We report two cases of COVID-19-associated organising pneumonia (OP) occurring beyond 4 weeks from the acute onset of symptoms. Both tested positive for SARS reverse transcription-PCR 2 months before presentation with a resolution of respiratory symptoms. The first case presented with residual fatigue and worsening exertional dyspnoea. Chest CT revealed an OP pattern. The second case presented with worsening cough and new-onset pleuritic chest pain with persistent radiological consolidation. A transbronchial lung biopsy confirmed OP. Both patients responded well to 12 weeks of steroid therapy. This case illustrates the rare presentation of OP as a late sequela of COVID-19 and the good response to steroid therapy.

Sooriyaghandan IV, Mohamad Jailaini MF, Nik Abeed NN, Ng BH, Yu-Lin AB, Shah SA, et al.

BMC Pulm Med, 2023 Jan 10;23(1):10.
PMID: 36627598 DOI: 10.1186/s12890-023-02304-y

BACKGROUND: Patient comfort during invasive and therapeutic procedures is important. The use of virtual reality (VR) devices during flexible bronchoscopy (FB) as a method of distraction to increase patient tolerability and improve satisfaction has not been investigated. We aim to assess the satisfaction and tolerability of participants undergoing FB with or without VR.
METHODS: This was a single-center, open-label study on patients undergoing bronchoscopy, randomized into the control and interventional (VR) groups. The control group received standard care during FB. The interventional group was given a VR device during FB showing nature videos with soothing instrumental music. Pain, breathlessness, and cough were evaluated using a 10 cm visual analogue scale administered before and after FB. Anxiety was assessed using the State-Trait Anxiety Inventory. Satisfaction questionnaire (5-point Likert scale) was given to participants post FB.
RESULTS: Eighty participants enrolled, 40 in each arm. Median (IQR) satisfaction score in the VR group was 5.0 (3.0-5.0), and in the control group was 4.0 (3.0-5.0); (p cough, and anxiety post FB were significantly less severe in the interventional group (p = 0.042, p = 0.001, p cough). There was a significantly lower anxiety score in the VR group.

Aziz NAI, Feisal NAS, Ibrahim TNBT, Cheah WY, Kamaludin NH

Med J Malaysia, 2024 Mar;79(Suppl 1):110-116.
PMID: 38555894

INTRODUCTION: Cleaners perform a vital role in environmental health by keeping the place clean, but they are also exposed to various hazards. Yet, there is a lack of effective and accessible occupational safety standard measures, thus making this to be difficult to monitor the long-term health effects of cleaners. This study aims to determine the respirable dust exposure on respiratory symptoms among cleaners in a public university in Selangor.
MATERIALS AND METHODS: A cross-sectional study was carried out among 51 cleaners. The respondents' background information and respiratory symptoms were gathered using a series of standardised questionnaires validated by the American Thoracic Society (ATS-DLD-78-A). The 8- hour respirable dust exposure to cleaners was measured using an air sampling pump (Gillian & Sensodyne Gil Air 3).
RESULTS: The mean of respirable dust was lower than permissible exposure limit with 0.63±0.57mg/m3. The respiratory symptoms among the cleaners showed no significant association between cough, phlegm, and breathing difficulties with working tenure. Meanwhile, wheezing and coughing with phlegm have an almost significant association with working tenure among cleaners with (Χ2=1.00, p=0.08) and (Χ2=1.00, p=0.07) respectively. Exposure to respirable dust has exhibited 6 times the prevalence of coughing with phlegm among cleaners (PR=6.28, 95% CI: 0.44, 89.38).
CONCLUSION: The findings of this study demonstrated that the cleaners were significantly affected by the respirable dust. The cleaners' working environment has caused them to be exposed to respirable dust.

PMID: 32284811 MyJurnal

In primary care, chest X-rays are commonly performed to assess patients presenting with a prolonged
cough. However, the extent to which the flms are accurately interpreted depends on the skill of the
doctors. Doctors with insufcient experience may miss an exact diagnosis when evaluating a flm,
especially in patients with nonspecifc symptoms, such as in the case discussed in this paper.

Surveillance data on the burden of pertussis in Asian adults are limited. This cross-sectional study evaluated the prevalence of serologically confirmed pertussis in adults with prolonged cough in Malaysia, Taiwan and Thailand. Adults (⩾19 years) with cough lasting for ⩾14 days without other known underlying cause were enrolled from outpatient clinics of seven public and/or private hospitals. Single blood samples for anti-pertussis toxin antibodies (anti-PT IgG) were analysed and economic impact and health-related quality of life (EQ-5D) questionnaires assessed. Sixteen (5·13%) of the 312 chronically coughing adults had serological evidence of pertussis infection within the previous 12 months (anti-PT IgG titre ⩾62·5 IU/ml). Three of them were teachers. Longer duration of cough, paroxysms (75% seroconfirmed, 48% non-seroconfirmed) and breathlessness/chest pain (63% seroconfirmed, 36% non-seroconfirmed) were associated with pertussis (P < 0·04). Of the seroconfirmed patients, the median total direct medical cost per pertussis episode in public hospitals (including physician consultations and/or emergency room visits) was US$13 in Malaysia, US$83 in Taiwan (n = 1) and US$26 in Thailand. The overall median EQ-5D index score of cases was 0·72 (range 0·42-1·00). Pertussis should be considered in the aetiology of adults with a prolonged or paroxysmal cough, and vaccination programmes considered.

Giant cell arteritis presenting as chronic cough and prolonged fever

Lim KH, Liam CK, Vasudevan AE, Wong CM

Respirology, 1999 Sep;4(3):299-301.
PMID: 10489679 DOI: 10.1046/j.1440-1843.1999.00195.x

A 62-year-old man presented with a 3-month history of chronic non-productive cough and unexplained fever. Further questioning revealed that he had headaches and myalgia. Bilateral thickened temporal arteries were noted on physical examination. The erythrocyte sedimentation rate was 96 mm in 1 h. A biopsy specimen of the left temporal artery showed inflammatory changes consistent with the diagnosis of giant cell arteritis. Commencement of prednisolone resulted in rapid and dramatic resolution of his symptoms. Physicians should be aware of respiratory symptoms in patients with giant cell arteritis in order to avoid delay in diagnosis and therapy of this condition.

PMID: 33664169

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a pandemic worldwide. On a daily basis the number of deaths associated with COVID-19 is rapidly increasing. The main transmission route of SARS-CoV-2 is through the air (airborne transmission). This review details the airborne transmission of SARS-CoV-2, the aerodynamics, and different modes of transmission (e.g. droplets, droplet nuclei, and aerosol particles). SARS-CoV-2 can be transmitted by an infected person during activities such as expiration, coughing, sneezing, and talking. During such activities and some medical procedures, aerosols and droplets contaminated with SARS-CoV-2 particles are formed. Depending on their sizes and the environmental conditions, such particles stay viable in the air for varying time periods and can cause infection in a susceptible host. Very few studies have been conducted to establish the mechanism or the aerodynamics of virus-loaded particles and droplets in causing infection. In this review we discuss the various forms in which SARS-CoV-2 virus particles can be transmitted in air and cause infections.

Fulltext Papillary Thyroid Carcinoma Presenting with Chronic Cough and Hemoptysis in Primary Care: A Case Report

Abd Hamid MF, Abdul Razak S, Azraai AM, Miptah HN

Am J Case Rep, 2023 Nov 10;24:e941089.
PMID: 37946402 DOI: 10.12659/AJCR.941089

BACKGROUND The article discusses an unusual case of papillary thyroid carcinoma in which chronic cough and hemoptysis were the predominant symptoms. While the more common causes of hemoptysis are pulmonary in origin, extrapulmonary etiologies have been reported, including thyroid carcinoma. The clinical presentation of thyroid malignancy in this case mimics many other common disorders, such as pulmonary tuberculosis, bronchogenic carcinoma, bronchiectasis, and chronic obstructive pulmonary disease. Hence, making it challenging to suspect early when patients present to primary care. CASE REPORT A 54-year-old woman presented with a chronic cough and hemoptysis in our Primary Care Medicine Clinic. While initial assessments in the primary care medicine clinic yielded no remarkable findings, a subsequent high-resolution computed tomography scan of the thorax uncovered a thyroid lesion. Subsequent evaluation in the hospital setting included an ultrasound examination, revealing multiple thyroid nodules, and fine needle aspiration that confirmed papillary thyroid carcinoma. She underwent total thyroidectomy with central and left lateral neck dissection, complicated by left vocal cord palsy. She received 2 cycles of periodic radioactive iodine therapy and injection laryngoplasty postoperatively. There was no evidence of iodin avid disease and recurrence of hemoptysis after surgery. CONCLUSIONS This case report emphasizes the significance of considering papillary thyroid carcinoma when assessing hemoptysis in the primary care setting, as early detection and treatment of it would result in a better outcome.

Practice of pharmaceutical care by community pharmacists in response to self-medication request for a cough: a simulated client study

Loh P, Lee JW, Karuppannan M, Chua SS

BMC Health Serv Res, 2023 Jun 20;23(1):657.
PMID: 37340333 DOI: 10.1186/s12913-023-09642-x

BACKGROUND: Community pharmacy practice worldwide has been shifting from product-focused to patient-oriented. However, due to the absence of separation between prescribing and dispensing in Malaysia, community pharmacists may have limited roles in the provision of pharmaceutical care to patients with chronic diseases. Therefore, the main functions of community pharmacists in Malaysia are related to self-medication requests for minor ailments and the supply of non-prescription medications. The objective of this study was to determine the practice of pharmaceutical care by community pharmacists within the Klang Valley, Malaysia in response to self-medication requests for a cough.
METHODS: This study utilised a simulated client method. A research assistant, acting as a simulated client, visited community pharmacies in the Klang Valley, Malaysia to consult the pharmacists on the treatment of a cough experienced by his father. Upon leaving the pharmacy premise, the simulated client entered the pharmacist's responses in a data collection form which was structured based on pharmacy mnemonics for the response to symptoms, OBRA'90 on counselling elements, the five practice principles of pharmaceutical care by the American Pharmacists Association and literature review. Visits to the community pharmacies were conducted from September to October 2018.
RESULTS: The simulated client visited a total of 100 community pharmacies. None of these community pharmacists practised adequate patients' data collection, with only a low proportion who practised all the components studied under medication information evaluation (13%), formulating a drug therapy plan (15%) and monitoring and modifying the plan (3%). Of the 100 community pharmacists, 98 recommended treatment but none of them provided all the counselling elements studied in implementing the drug therapy plan.
CONCLUSION: The present study showed that community pharmacists within the Klang Valley, Malaysia were not providing adequate pharmaceutical care services to patients seeking self-medication for a cough. Such practice may compromise patient safety if inappropriate medicines or advice are given.

PMID: 33505949 DOI: 10.3389/fpubh.2020.567395

Clinical characteristics are essential for the correct diagnosis of diseases. The current review aimed to summarize the global clinical characteristics of the COVID-19 patients systematically and identify their diagnostic challenges to help the medical practitioners properly diagnose and for better management of COVID-19 patients. We conducted a systematic search in PubMed, Web of Science, Scopus, Science Direct, and Google Scholar databases for original articles containing clinical information of COVID-19 published up to 7th May 2020. Two researchers independently searched the databases to extract eligible articles. A total of 34 studies from 8 different countries with 10889 case-patients were included for clinical characteristics. The most common clinical symptoms were cough 59.6, fever 46.9, fatigue 27.8, and dyspnea 20.23%. The prominent laboratory findings were lymphocytopenia 55.9, elevated levels of CRP 61.9, aspartate aminotransferase 53.3, LDH 40.8, ESR 72.99, serum ferritin 63, IL-6 52, and prothrombin time 35.47%, and decreased levels of platelets 17.26, eosinophils 59.0, hemoglobin 29, and albumin 38.4%. CT scan of the chest showed an abnormality in 93.50% cases with bilateral lungs 71.1%, ground-glass opacity 48%, lesion in lungs 78.3%, and enlargement of lymph node 50.7%. Common comorbidities were hypertension, diabetes, obesity, and cardiovascular diseases. The estimated median incubation period was 5.36 days, and the overall case fatality rate was 16.9% (Global case fatality outside China was 22.24%: USA 21.24%, Italy 25.61%, and others 0%; whereas the case fatality inside the Hubei Province of China was found to be 11.71%). Global features on the clinical characteristics of COVID-19 obtained from laboratory tests and CT scan results will provide useful information to the physicians to diagnose the disease and for better management of the patients as well as to address the diagnostic challenges to control the infection.

An outbreak of pneumonia occurred among 1,491 recruits undergoing training at the Army Recruit Training Center, Port Dickson, Negeri Sembihxn, between july to August 2000. They had reported for training 2 weeks before and were placed in new modern concrete 4 floors buiMing with well ventilated dorm. A total of 70 recruits were ajjfected and one died. The attack rate was 4.7% and the case fatality rate was 1.4%. The outbreak ajfected recruits from all the jive companies; J (21/299,
30.0%) , G (19/298, 27.1 %), I (14/298, 20.0%), H (13/298, 18.6%) and F (3/298, 4.3%) . The main presenting symptoms were fever (68/70, 97.1%), cough (62/70, 88.6%), and chest pain (35/70, 50 .0%) . This was a common site outbreak with the mode of spread from person to person through infected droplet. The outbreak has three peaks, which was at lst, 4th and 6th week respectively and lasted for eight weeks. The organisms isobted through blood culture were Streptococcal pneumoniae and Klebsiella pneumoniae. All the cases were managed and treated as in-patients at four dijjferent hospitals depending on the severity of the illness. The main control activities carried out were separation of ill recruits from the healthy, reducing the number of recruits in the dormitories and encourage recruits to drink a lot of water while in training.
