Lateral abdominal wall hernias after coughing: a single center experience.
Hernia
December 2024
Department of Surgery, Cleveland Clinic Center for Abdominal Core Health Cleveland Clinic Foundation, 9500 Euclid Avenue, Cleveland, OH, 44195, USA.
Purpose: Forceful coughing is assumed to be an uncommon etiology for lateral abdominal wall hernias. The literature regarding this topic is very limited and there is a lack of consensus in management, both operative and non-operative. We aim to report our center's experience in repair of lateral abdominal wall hernias secondary to vigorous coughing.

The longitudinal motion and the intramural shear strain of the arterial wall increase dramatically in response to blood pressure, thereby impacting the vascular wall microenvironment. Exposure to a sedentary lifestyle has been identified as an independent risk factor for cardiovascular disease, but it has been shown that intermittent physical activity embedded into everyday life is enough to improve cardiovascular health. Marked changes in longitudinal motion already at low workload may explain this finding.

Apical hook opening is crucial for seedling establishment and is regulated by unequal distribution of the hormone auxin through unknown mechanisms. In this issue of Developmental Cell, Walia et al. demonstrate that apical hook opening is an output of tissue-wide forces; auxin and cell wall integrity (CWI) signaling interact to restrict elongation to the concave side of the apical hook.

Article Synopsis
- - The Lambert diffuse reflection model is crucial for predicting sound behavior in both indoor and outdoor environments, revealing differences in reflection strength between diffusely and specularly reflecting walls.
- - Borish highlighted that a diffusely reflecting wall produces a stronger reflection (3 dB) than a specular wall when the source and receiver are aligned in a specific way, which raises questions about energy distribution.
- - The research clarifies that the difference in perceived reflection strength relates to the type of receiver used and confirms that energy conservation is upheld, providing a better understanding of the Lambert reflection model's implications.
