    Journal of Public Health Germany, 2023
    Gastroenteritis is a digestive disorder among children with symptoms of abdominal cramps, diarrhoea, and vomiting. This study aimed to determine the prevalence of gastroenteritis in children in the Bannu district in 2019, and also contributed for adopting preventive measures to reduce mortality in children. A retrospective study was conducted to determine the prevalence of gastroenteritis in children in Bannu. The data were collected from official registers of admission maintained in the children wards in the Women and Children Hospital, Bannu. Patients with symptoms of gastroenteritis at the outpatient department were admitted to one of the children wards. Overall, 1456 children—897 (61.4%) males and 559 (38.6%) females—suffered from gastroenteritis during the study period. The age group ≤6 months demonstrated the highest share (37.8%), followed by >6 m ≤ 1y (35.5%), >1y ≤ 2y (15.8%), >2y ≤ 5y (7.3%), >5 ≤ 10y (3.2%), and > 10y ≤ 15y (0.4%). Overall, 89.1% of cases were from children ≤2 years old and 96.4% of cases were attributed to children ≤ 5 years of age. April demonstrated the highest percentage of prevalence of 17.7, followed by May (13.5%), November (13%), June (11.7%), September (10.4%), October (9.8%), July (9.5%), August (8.4%), March (3.4%), and February (2.6%). The age group ≤6 m was the dominant group during February through May and was replaced by the age group >6 m ≤ 1y during August through November. Gastroenteritis showed a reduced prevalence when shifted from lower to higher age groups. Being male and age group ≤6 m showed the highest prevalence of gastroenteritis with the peak of disease in April. Further research is needed to determine the cause-based prevalence of different gastroenteritis cases in the study area.

    Egyptian Journal of Bronchology, 2022
    Background Asthma and chronic obstructive pulmonary disease are the major airway diseases and are increasingly important causes of mortality, morbidity, and disability globally. This cross-sectional study was conducted to determine monthly and seasonal patterns of asthma and chronic obstructive pulmonary disease in the study area during 2020–2021. The data of the indoor patients for the study period were obtained from the official records maintained in the District Head Quarter teaching hospital Dera Ismail Khan. Results A total of 2179 cases of asthma were recorded including 1609 (73.8%) in 2020 and 570 (26.2%) in 2021, and 740 cases of the chronic obstructive pulmonary disease were also recorded in 2020. Overall asthma was highest in March with 1128 (51.8%) cases and was lowest in July with 29 (1.3%) cases. Seasonal prevalence/pattern show that asthma relatively more prevailed during winter and early spring (December through March). Out of a total of 740 cases of chronic obstructive pulmonary disease, the highest 405 (54.7%) cases were recorded in February and the lowest 0 in April. Seasonal distribution indicated that chronic obstructive pulmonary disease was relatively higher in winter (January–February). Conclusions Seasonal variation and pattern in prevalence exist both in asthma and chronic obstructive pulmonary disease as both indicated relatively higher prevalence in winter compared to summer and autumn.

    Egyptian Liver Journal, 2022
    Background Viral hepatitis causes both liver inflammation and damage and is a serious health problem. Methods The indoor data of different types of hepatitis were collected from the official records of the administration of District Head Quarter Hospital Dera Ismail Khan for 2 years (2020–2021). Results A total of 1193 cases of viral hepatitis during the study period were found including viral hepatitis C accounted for 547 (45.9%) cases, followed by the co-infection of viral hepatitis A and E 367 (30.8%) cases, and viral hepatitis B 279 (23.4%) cases. March showed the highest prevalence of hepatitis (33.2%), followed by February (10.2%). The co-infection of hepatitis A and E showed a relatively higher prevalence in 6 months from May to November except September including a peak in June (76.5%) during the study period. While viral hepatitis B demonstrated a comparatively higher percentage prevalence in both February and September with a peak in February (68%), and viral hepatitis C is dominant in January, March, and December with a peak in March (83.8%). Conclusion All types of viral hepatitis showed variation in prevalence over months and monthly variation concerning peak prevalence exists among different types of hepatitis. Both viral hepatitis A and E demonstrated similar trend in relative prevalence in both 2020 and 2021. Nevertheless, viral hepatitis A and B showed monthly and seasonal variation in relatively prevalence in both years. The study help in adopting strategies for the prevention of viral hepatitis in the study area.

    Egyptian Journal of Bronchology, 2022
    Background Lower respiratory tract infections are the leading cause of death in children globally and are transmitted by inhaling airborne droplets. The study demonstrated the prevalence of lower respiratory tract infections in children admitted to the Women and Children Hospital Bannu from February through November 2019. The cross-sectional study was conducted by obtaining indoor data from the official record maintained in the children’s wards. Results Males accounted for 649 (61.6%) and females 405 (38.4%) cases out of 1054 cases of the disease. Age group of ≤ 6 months showed 36.2% prevalence, followed by > 6 m ≤ 1 y (25.6%), > 1 y ≤ 2 y (17.1%), > 2 y ≤ 5 y (14.3%), > 5 ≤ 10 y (6.0%), and > 10 y ≤ 15 y (0.8%). Pediatric patients of age ≤ 2 y and ≤ 5 y contributed 78.9% and 93.3% to overall disease, respectively. The disease was at its peak in February (17.9%) while lowest in May (5.5%). The age group (≤ 6 m) was the dominant group in all months except August when replaced by the age group (> 6 m ≤ 1 y). The disease revealed higher prevalence during February-April and October-November. Conclusions Different age groups showed variation in the prevalence of the disease with an age group of ≤ 5 y contributing the largest share and seasonal peaks in the disease occurred. The present findings help in adopting strategies for effective control of the disease in different age groups of the children for their peak season.

    Background and Objectives: Malaria is one of the serious infections worldwide and is a global major health concern. The preset study aimed to determine the prevalence of malaria in Kot Kashmir (during 2017–2018) and Serai Gambila (in 2015) in the District Lakki Marwat. Methods: The retrospective study was conducted by collecting the data recorded in the official registers and data were consolidated into different age groups and months. Results: Overall Plasmodium vivax accounted for >98% and Plasmodium falciparum <2% of malaria and males showed 56.5% of malaria. August showed the highest prevalence of 20% cases, while February revealed the lowest prevalence of 2.1% cases. Overall males showed higher rates of malaria than females in all the months and all the age groups except equal rates for the month of February in the age group <5 years and May in the age group of 31–45 years, while the age group of 5–14 years showed the highest prevalence of 242 (41.4%) cases, and the age group of 46–60 years demonstrated the lowest prevalence of 24 (4.1%) cases, and patients of ≤30 years contributed to 85.5% of malaria. Age groups of ≤14 years contributed to 78.2% of malaria in Kot Kashmir, while, age groups of 5–30 years demonstrated 75.7% of malaria in Serai Gambila. Conclusions: Overall malaria, as well as vivax malaria in males, steadily increased from April to August followed gradually decreased from the age group of 15–30 years to age group >60 years.

    Integration of chemical and biological controls is an important tactic of integrated pest management. Trichogramma chilonis (Ishii) is an important natural enemy of lepidopteran pests. However, the minute parasitoids are adversely affected by most pesticides. Effects of acute mortality and parasitism of selected novel pesticides on adults of T. chilonis exposed to the dried residues of field doses for 24 h on glass surface were evaluated. Acetamiprid, spinetoram and fipronil induced mortality of > 95%, followed by abamectin (ranged 71.3–83.5%) in four residual-age treatments. Spiromesifen, haloxyfop-p-methyl, mixture of pyraclostrobin + metiram and mixture of trifloxystrobin + tebuconazole revealed mortality of ≤ 36.4% in all treatments (when female parasitoids were exposed to 1 day, 5 days, 10 days and 15 days after treatments). Bispyribac sodium induced mortality of ranged 51.1–54.9% in 1- and 5-day treatments, and approximately ≤ 10% in others (10-day and 15-day treatment). Eggs of Sitotroga cerealella in acetamiprid, spinetoram, fipronil and abamectin treatments showed ≤ 36% parasitism relative to controls in all treatments. Spirotetramat, bispyribac sodium, nicosulfuron, trifloxystrobin + tebuconazole and pyraclostrobin + metiram resulted in parasitism rates of 49.2–71.2% and 81.5–93.8% in 1-day and 15-day treatment, respectively. Helicoverpa armigera nucleopolyhedrovirus, chlorantraniprole, spiromesifen haloxyfop-p-methyl, chlorothalonil + procymidone and myclobutanil showed ≥ 80.6% parasitism in all treatments. Thus, acetamiprid, spinetoram, fipronil and abamectin were the most harmful among the pesticides used for both emergence and parasitism, while remaining pesticides demonstrated relatively compatibility with the emergence as well as parasitism by the minute parasitoids, and can be integrated with the minute parasitoid in agroecosystem.
