“…Ashley has reported an excess of cases during spring, implicating a high prevalence of viral infection during these months 16 . Similar reports have been shown in the study by Sanda et al implicating intense sandstorm as cause in the Spring months, in the Arabian Peninsula 7 .…”

Background: Acute appendicitis is the most common general surgical disease, worldwide. The exact etiology is still in conjecture. However, the inadequate fiber in diet, smoking, mechanical obstruction in appendiceal lumen, has been attributed as factors for appendicitis. Appendicitis presents throughout months of the year, however, incidence increases in particular months. The objective of this study is to observe the appendicitis incidence variation with months of the year in high altitude region of Nepal. Methods: The cross-sectional retrospective study was conducted in the Karnali Academy of Health Sciences, Jumla situated at the altitude above 2500 m from sea level. The clinical data were retrieved from the hospital record book in the Operation Theater that included age, gender, ethnicity, month of the appendectomy executed, pre-operative clinical presentation, and operative findings. The period of study was from July 2014 to March 2020. The data were entered in Microsoft Excel software and descriptive analysis was done to get mean, median percentage, standard deviation by SPSS 16. Results: A total of 119 appendectomies performed during 5 years period, from 2014 to 2020, in the surgery department of Karnali Academy of Health Sciences were recorded. The mean age of appendectomy was 27 years. There were 53% female (n=64) and 46% male (n=55) patients. The months in which the highest appendectomy executed were July/August/September and February with 16% (n=19), 13.4% (n=16), (n=15) 12.6% and 13.4% (n=16) respectively. The lowest incidence was 1.7% in the month of April. Conclusion: The incidence of appendicitis is high in the months from July to September with the lowest incidence is in the months of April and May. This information could be useful to decrease the disease-associated morbidity and mortality as well as it can be useful for hospital administration for enrolling the needed health-workers in those particular time periods.

“…On the other hand, a study conducted in northern Saudi Arabia revealed an increased incidence in spring months, which coincide with the sandstorm season. is might be attributed to dust and allergen burden to the lymphoid tissue [4]. In other areas like Nigeria, Turkey, certain parts of the United States and the United Kingdom, different results were obtained.…”

“…Incidence is increased in certain ethnic groups and complications are increased in minorities, likely due to lack of healthcare access. Cases are classified into simple (nonperforated) and complex (gangrenous, perforated, and pelvic/abdominal abscess) [2][3][4][5].…”

Objectives. To investigate whether the incidence of acute appendicitis increases in summer and whether complicated cases present more in summer. Methods. A single-center cross-sectional, retrospective study on 697 cases of appendicitis admitted in the year 2018. Inclusion criteria: patients admitted with acute appendicitis who underwent appendectomy of all ages. Exclusion criteria: conservative management. Analysis was performed using Microsoft Excel. Pearson correlation coefficient was calculated to assess the correlation between monthly incidence of appendicitis and mean temperature in that month. Results. Fifty-one patients who were managed conservatively were excluded. Accordingly, 646 patients were included. Ages ranged from three to 77 years. Males comprised the majority (500, 77.4%). Gangrenous, perforated, and purulent appendices were regarded as complicated appendicitis. The highest number of cases were admitted in summer (234), comprising 36.2% of cases. Complicated cases were equal to 65, of which 23 (35.4%) were admitted in summer and 30 (46.2%) in winter. The highest number of cases was during the month of July (68), while the lowest (40) was during February. This corresponded to the highest recorded mean temperature (36.2°C) and second lowest (19.8°C), respectively. Moderate positive correlation (Pearson’s R 0.5183) between the monthly incidence of appendicitis and the mean temperature is noted. Conclusion. More cases of appendicitis were noted during summer. Monthly incidence correlated positively with the temperature. Larger numbers over several years are needed to draw better conclusions and reach the possible causes behind such variation.

“…The reasons for increased incidence of AA during the warm period are not clear, although various speculations have been proposed such as the effect of dehydration, lower bowel movements or the effects of diet. Otherwise, in northern Saudi Arabia, incidence of acute appendicitis increased in the spring months coinciding with the onset of the sandstorm season [28]. This increase has been explained by the intense challenge to the mucosa associated lymphoid tissue from allergens, bacteria and viruses present in the dust.…”
