Article Synopsis
  • Hidradenitis suppurativa (HS) is a painful inflammatory skin condition that leads to nodules, abscesses, and scars, and can get complicated with diseases like amyloidosis.
  • A 53-year-old male with a history of HS and amyloidosis was hospitalized for acute renal failure and sepsis, while on adalimumab treatment.
  • After 15 days of care including hemodialysis and antibiotics, his sepsis improved, but he was transitioned to a regular hemodialysis program due to the risk of chronic kidney failure from infections linked to his HS and amyloidosis.

Background: is one of the most life-threatening multidrug-resistant pathogens worldwide. Currently, 50%-70% of clinical isolates of are extensively drug-resistant, and available antibiotic options against infections are limited. There is still a need to discover specific bacterial antigenic proteins that could be effective vaccine candidates in human infection.

The causative agent of anthrax, Bacillus anthracis, evades the host immune response and establishes infection through the production of binary exotoxins composed of Protective Antigen (PA) and one of two subunits, lethal factor (LF) or edema factor (EF). The majority of vaccination strategies have focused upon the antibody response to the PA subunit. We have used a panel of humanised HLA class II transgenic mouse strains to define HLA-DR-restricted and HLA-DQ-restricted CD4+ T cell responses to the immunodominant epitopes of PA.

Objective: , a Gram-negative pathogen, especially which produces carbapenemase, is seen as a major threat to public health due to rapid plasmid-mediated spread of resistance and limited therapeutic options available for treatment. Although colistin has been recognized as a "last resort" antimicrobial for multidrug-resistant infections, these isolates have developed resistance to colistin as a result of its intensive use. The aim of this study was to evaluate the efficacy of double-carbapenem treatment of colistin-resistant experimental sepsis in mice.

Born in 1884 in Balıkesir, Turkey, Ömer Seyfettin was a leading figure among modern Turkish short story writers whose death in 1920 at the age of 36 led to long-term speculations about his fatal illness. In order to pay homage to his memory in the centennial of his death and to shed light on his later medical condition, this paper seeks to reexamine his last days from a medico-historical perspective. Our findings indicate that there was a notable decline in his health occurring after 1917 when he was confined to social isolation.
