[Vulnerability of patients with intellectual disabilities in emergency].

People with intellectual disabilities should receive the same healthcare as those offered to the general population. However, they have weakened defense capabilities compared to the rest of the population and are therefore more vulnerable, with somatic, psychological, and psychosocial crises being more frequent and becoming complicated to manage. Usually, a primary assessment can reduce the need for transfer to emergency departments, but some situations may become complex and require hospital-based care.

The diagnostic dilemma: Giant Mucocele of the appendix-challenging conventional thinking.

This article reports on a 76-year-old male patient diagnosed with a mucocele of the appendix. A mucocele of the appendix is a benign fluid-filled swelling caused by the accumulation of mucus in the appendix due to a blockage in its discharge route. The patient presented with symptoms of chronic constipation and rectal tenesmus and was diagnosed through physical examination, imaging studies and laboratory tests.

Perforated mediastinal gastric volvulus: an uncommon complication of hiatal hernia.

A woman in her 50s was admitted to the emergency department with a 3-day history of abdominal pain, mainly in the right hypochondrium, radiating to the back, associated with postprandial vomiting and dysphagia. The abdominal ultrasound study found no abnormalities. Laboratory tests showed increased C-reactive protein levels, creatinine and high white blood cell count without a left shift.

Polarized skylight navigation.

Vehicle state estimation is an essential prerequisite for navigation. The present approach seeks to use skylight polarization to facilitate state estimation under autonomous unconstrained flight conditions. Atmospheric scattering polarizes incident sunlight such that solar position is mathematically encoded in the resulting skylight polarization pattern.
