Objective:
To determine if short term exclusive (EBF), combined breastfeeding (CBF), or an early start of other kind of food constitute risk factors for appendicitis in children.
Materials And Methods:
By means of a case-control study, the mothers of 200 children up to 16 years with a diagnosis of acute appendicitis and 200 matched controls were interviewed regarding the duration of breastfeeding and the start of other foods. Data were analyzed to calculate chi-square c2; odds ratio (OR) was used to calculate risk factors, confidence intervals (CI 95%) were also determined.
Results:
There was no EBF in 52 cases (26%), or in 5 controls (2.5%) (p< 0.001). EBF lasted for 2.3 +/- 1.8 months in cases and 3 +/- 1.1 months in controls (p< 0.001). CBF lasted for 8.1 +/- 7.5 months in cases and 8.8 +/- 3.5 in controls (p< 0.001); ablactation was started at 4.4 +/- 1.3 months in cases and at 4.7+/-1.2 in controls (p< 0.05). The OR of developing appendicitis for non- EBF was 10.4 (CI 95% 4 - 26.5), for ablactation before 4 months 1.4, (CI 95% 0.9 - 2) and for CBF for less than 6 months 4.6, (CI 95% 2.3 - 8.3).
Conclusions:
The risk of developing appendicitis is higher among children who never received EBF and who were breastfed for less than 6 months.

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Cholecystitis
