Article Synopsis
  • High levels of ACTH are used to diagnose pituitary pars intermedia dysfunction (PPID) in older horses, but other factors like insulin dysregulation may also affect ACTH levels.
  • A study involving 13 horses and 11 ponies aimed to find a relationship between high insulin and high ACTH in these animals without visible signs of PPID.
  • Results showed a positive correlation between ACTH and insulin levels in autumn, indicating that high ACTH may be linked to insulin dysregulation in the absence of PPID symptoms, warranting further research.

The equine microbiome can change in response to dietary alteration and may play a role in insulin dysregulation. The aim of this study was to determine the effect of adding pasture to a hay diet on the faecal bacterial microbiome of both healthy and insulin-dysregulated ponies. Faecal samples were collected from 16 ponies before and after dietary change to enable bacterial 16S rRNA sequencing of the V3-V4 region.

Equine laminitis is a disease of the digital epidermal lamellae typified by epidermal cell proliferation and structural collapse. Most commonly the disease is caused by hyperinsulinemia, although the pathogenesis is incompletely understood. Insulin can activate the epidermal growth factor (EGF) system in other species and the present study tested the hypothesis that upregulation of EGF receptor (EGFR) signalling is a key factor in laminitis pathophysiology.

Granuloviruses are widespread pathogens of Plutella xylostella L. (diamondback moth) and potential biopesticides for control of this global insect pest. We report the complete genomes of four Plutella xylostella granulovirus isolates from China, Malaysia, and Taiwan exhibiting pairs of noncoding, homologous repeat regions with significant sequence variation but equivalent length.

Enterococcus faecalis is one of the leading causes of nosocomial infections and is a common commensal organism in humans and other animals. In this study, we report a draft genome sequence for the E. faecalis strain PF3, isolated from Adélie penguin feces collected from Warriner Island, Antarctica.

This article presents the story of the development of an expanded transposition flap that evolved from a desire to optimally reconstruct facial burn deformities. The story spans 25 years and demonstrates how an algorithm was developed from its use, and how the algorithm is used to analyze large facial burn deformities and provide a reconstructive surgical decision making tree. The experience suggests that versatility, reliability, and minimization of the donor site defect and reconstructive time are all benefits of this approach.

Objective: To present a case report of a patient with an open fracture and severe burns and review the literature.

Methods: The patient was treated with intubation, intravenous antibiotics, and debridement and intramedullary nailing for the femur fracture. He later underwent multiple burn excision procedures with allograft and autograft skin coverage.

Background: Reconstruction of major facial soft-tissue deformities and deficits is a continuing challenge for surgeons who wish to reliably restore facial function and appearance. A primary problem is deficiency of well-matched donor skin. Others include the unique characteristics of facial skin, the fine anatomical nuances, and the unique functional demands placed on the face making reconstruction difficult.

Background: The reconstruction of major burn and other deformities resulting from significant soft tissue deficits of the face and neck is a continuing challenge for surgeons who wish to reliably restore facial function and aesthetic appearance. A primary problem is deficiency of well-matched donor skin. Other problems include the unique characteristics of facial skin, the fine anatomic nuances, and the unique functional demands placed on the face.

Article Synopsis
  • The study found that 46% of burn reconstruction patients experienced mild to moderate depression symptoms.
  • Female patients were more common in this group and tended to have different injury characteristics compared to male patients.
  • Body image dissatisfaction and physical function were significant predictors of depressive symptoms, highlighting the need for psychological screening in these patients.

Objective: Burn wound depth is a significant determinant of patient treatment and morbidity. While superficial partial-thickness burns generally heal by re-epithelialization with minimal scarring, deeper wounds can form hypertrophic or contracted scars, often requiring surgical excision and grafting to prevent a suboptimal result. In addition, without timely intervention, more superficial burn wounds can convert to deeper wounds.

Severe burns induce pathophysiologic problems, among them catabolism of lean mass, leading to protracted hospitalization and prolonged recovery. Oxandrolone is an anabolic agent shown to decrease lean mass catabolism and improve wound healing in the severely burned patients. We enrolled 81 adult subjects with burns 20% to 60% TBSA in a multicenter trial testing the effects of oxandrolone on length of hospital stay.

Background: Basaloid follicular hamartomas (BFH) are rare, benign, adnexal lesions with diverse clinical presentations. Previous studies documented BFHs with fibroepithelioma of Pinkus-like proliferations, or proliferations that resemble trichoepitheliomas.

Objective: We report on a patient with linear, unilateral BFH and extensive trichoblastomatous proliferations involving the right arm, torso, and leg.
