CASE REPORT: We report a 37-year-old woman with recurrent right iliac fossa pain. Computed tomography scan revealed a caecal mass suggesting complete inversion or intussusception of the appendix, which was confirmed by pathologic microscopic examination. This case report discusses appendiceal intussusception with emphasis on diagnosis and treatment options.
DISCUSSION: Appendiceal intussusception is a rare entity and the complete type typically presents as a polypoid lesion located at the appendiceal orifice in the caecum. It is imperative to include this entity in the differential diagnosis of caecal mass, especially during colonoscopy, as the removal of this polypoid lesion can result in a devastating caecal perforation or haemorrhage.
Methods: Forty participants were recruited for the study (20 with asymptomatic pronated feet and 20 with non-pronated feet). Foot assessment was conducted by navicular drop and rear-foot angle tests. Hip joint kinematics were measured via MVN Xsens system 3D-motion capture from sagittal, frontal and transverse planes during gait. An independent t-test was used to identify differences in kinematic variables.
Results: Both groups were similar in characteristics, and there were no significant differences between the groups in age (P = 0.674) and BMI (P = 0.459). However, there was a significant difference in arch height (P = 0.001) and rear-foot angle (P = 0.001). Our findings showed there were insignificant differences between the asymptomatic pronated foot and non-pronated foot control groups in hip joint kinematics of sagittal (P = 0.618), frontal (P = 0.276), and transverse (P = 0.337) planes during a full gait cycle.
Conclusion: Patients with asymptomatic pronation of the foot and non-pronation of the foot showed similar movement patterns of hip kinematics in all three planes. The findings of the present study highlight the need for clinicians to consider foot alignment when examining patients with asymptomatic pronation of the foot and non-pronation of the foot.
