Background: Surgical treatment for rectal cancer may cause complications that exacerbate the condition, lengthen hospital stays, and raise healthcare costs. Rectal cancer surgery complications can be detected immediately with postoperative C-reactive protein (CRP) monitoring. Elevated levels of CRP indicate the presence of inflammation and can serve as a predictive factor for future outcomes.

Inguinoscrotal hernia (ISH) is an entity for which treatment is under debate. Open surgery is the standard approach, but the laparoscopic technique has a great outcome when used by experienced surgeons. Seroma is one of the complications following laparoscopic hernia repair for these scrotal hernias, which is due to the large hernia sac, usually transected, leaving in place a remnant of the sac.

Bilateral inguinal hernia can be safely repaired simultaneously, open or minimally invasive, in an elective sce-nario. The choice of surgical approach depends on the patient's status, hernia characteristics, surgeons and patient preferences. Whether age criteria should be considered when selecting between the two approaches is still a matter of debate.

Aim: The authors set out to evaluate the correlations between three of the main morphological aortic parameters (elastic fibers - FE, collagen fibers - FCOL, and smooth muscle fibers - FM) and the cause of death.

Materials And Methods: Study groups included 25 cases died of a vascular disease (V_P), 37 cases died of a non-vascular disease (NV_P) and 28 cases died of a violent/suspect non-pathological cause of death (V_Dth), the latter group representing also the control group. Four aortic cross-sections (base, arch, thoracic, and abdominal regions) were collected during autopsy from the selected cases, fixed in 10% buffered formalin and first of all photographed together with a calibrating ruler.

Rhabdomyosarcoma is a rare tumor that is diagnosed mostly in children and adolescents, rarely in adults, representing 2-5% of all soft tissue sarcomas. It has four subtypes that are recognized: embryonal (50%), alveolar (20%), pleomorphic (20%), and spindle cell/sclerosing (10%). The diagnosis of rhabdomyosarcoma is based on the histological detection of rhabdomyoblasts and the expression of muscle-related biomarkers.

Article Synopsis
  • The study aimed to investigate how aging affects the thickness of the intima and media layers of the aortic wall by analyzing tissue samples from 90 autopsied cases across different ages.
  • The researchers found that the intima layer thickens continuously with age and location, while the media layer shows a conflicting trend, decreasing in thickness from the base to the abdominal region but increasing with age.
  • The findings highlight distinct aging patterns for each aortic layer that vary by age, gender, and location, suggesting the need for more in-depth and standardized future research.
