“…The annual pattern of variation in pollen concentration was very similar at both stations in the 2 years, with maximum daily mean concentrations recorded during August for the Amaranthaceae pollen (2017–2018) and March for the pollen of Poaceae (2018–2019). A similar pattern was found in other countries in the Middle East, such as Kuwait [10, 11 ] and Saudi Arabia [12, 13 ]. These periods may represent the pollen seasons in Qatar.…”

Background Pollen is a major cause of allergic respiratory diseases. In Qatar, data on the presence and prevalence of allergenic airborne types of pollen is quite limited. Methods The study aimed to determine and correlate the most frequently implicated airborne pollen detected by aerobiological monitoring samplers in respiratory allergy symptoms. An aerobiological survey was started on May 8, 2017. Airborne pollen was collected using two Hirst type seven-day recorder volumetric traps. Skin prick test in patients attending allergy clinics in Doha using commercial extracts was conducted. Results Twenty-five pollen types representing the native, as well as the introduced plants, with a relatively low daily mean concentration were observed from May 2017 to May 2019. The highest pollen concentrations were reached by Amaranthaceae (58.9%), followed by Poaceae (21.7%). SPT revealed a comparatively higher degree of sensitization to pollen. Among 940 patients, 204 were sensitized to pollen (54% female) with 135 (66.2%) and 114 (55.8%) to Amaranthaceae and Poaceae, respectively. Some patients had polysensitization. There was a statistically significant association between Amaranthaceae, and asthma (r = 0.169, P = 0.016) and allergic rhinitis (r = 0.177, P = 0.012). Conclusions This is the first study to monitor airborne pollen in the state of Qatar. The main pollen detected were Amaranthaceae and Poaceae. Pollen may represent a possible exacerbating factor in adult patients with allergic diseases such as asthma and allergic rhinitis.

“…However, data in the Arabian Gulf are scarce [9 ]. Among the countries in this region, Kuwait was the origin of many investigations describing the seasonal distribution of airborne pollen [10, 11 ], followed by Saudi Arabia [12, 13 ]. All the previous studies were conducted by using the Hirst type volumetric spore trap.…”

“…Our previous study 16 on the pediatric population of Jazan region also reported the highest incidence of respiratory tract infections. Higher incidence of these respiratory tract infections may be due the high percentage of airborne Amaranthus pollen in Jazan which potentially causes allergic respiratory diseases as reported by Hasnain et al 17 On the striking feature was that CNS disorders were not common (3.29%) which is in contrast to the data from the western countries. This may be due to the fact that most of the elderly people may be living with their family and were receiving proper family support and care, consequently avoiding these conditions.…”

Inappropriate drug prescribing is a global problem affecting the healthcare system. This study was performed to assess the drug prescribing pattern in elderly persons as these are exposed to polypharmacy because of multiple chronic conditions. There are a lot of risk factors for polypharmacy which include age, sex, race, health status, educational level and a number of chronic diseases which generally come with increasing age. This study was carried out to find rational use of prescribed drugs in the diseases with respect to the elderly patients registered in General Hospital of Jazan, KSA and to also investigate polypharmacy. A prospective, cross-sectional study was carried out in hospitalized elderly patients(age, >65years) selected from the month of November 2012 to October 2013 which consists of: Drug prescription pattern as per Beer's criteria, Percentage of category of drugs prescribed as per WHO core indicator, Missing Item Prevalence. Among 1034 elderly patients, the average age of study patients was 72years. The diseases found during this study were, hypertension, GIT disorders, cardiovascular diseases, respiratory tract diseases, diabetes mellitus. The average number of diseases present is 4+1 and the average number of drugs overall was 7+1. Among systemic route, commonly prescribed therapeutic class of medications were antibacterials(70.5%) and among oral route, pantoprazole was the most commonly prescribed medication(61.2%). This study demonstrates the prescribing patterns of drugs and usage of drugs in the elderly patients in the Jazan region of Saudi Arabia.

Inappropriate drug prescribing is a global problem affecting the healthcare system. This study was performed to assess the drug prescribing pattern in geriatric, paediatric and obstetrics and gynaecology department. Patient's chances of exposure to poly pharmacy are more, therefore, this study was carried out to find out the rational use of prescribed drugs in Jazan general hospital. A prospective cross sectional (descriptive) study was carried out and a total of 3070 prescriptions were collected for the study during November, 2012 to October, 2013. 1034, 1024, and 1012 prescriptions from geriatric, pediatric and obstetrics and gynaecology department respectively were collected. The average numbers of drugs used per patient were 3.1, 7.4 and 3.3 for geriatric, pediatric and obstetrics and gynaecology department patients respectively. Prescription pattern of the drugs for pediatric patients consists of antibiotics, analgesics and antipyretics mainly. For geriatric patients among systemic route, commonly prescribed therapeutic class of medications were antibacterials (70.5%), and among oral route, pantoprazole was the most commonly prescribed medication (61.2%). For obstetrics and gynaecology department patients the most frequently prescribed drugs were oral iron, folic acid preparations, antibiotics and analgesics. There is a high level of exposure to medication in paediatric and geriatric population. In obstetrics and gynaecology department, the average numbers of drugs per prescription were slightly higher compared to the standard set by World Health Organisation (WHO) but majority of the drugs were prescribed as per United State Food and Drugs Administration (USFDA) category A (the safest category during pregnancy).
