Harvey Cushing: early use of tendon transfers for repair of foot deformity: A historical case report

We describe 4 cases of tendon transfers for correction of foot deformities, which were performed by Harvey Cushing in 1898

Regression of cutaneous invasive squamous cell carcinoma in a patient with chronic cutaneous graft versus host disease

Numerous complications can be observed in the post-transplant period among recipients of hematopoietic stem cells including graft-versus-host disease (GVHD), which is associated with significant morbidity and mortality. On the other hand, graft versus tumor (GVT) effect is a well-described phenomenon in patients with hematologic malignancies and has also been reported in renal cell cancer, ovarian cancer, breast carcinoma, and melanoma. We describe spontaneous regression of a cutaneous invasive squamous cell carcinoma and multifocal atypical intraepidermal proliferations in a patient with chronic graft-versus-host disease following initiation of extracorporeal photopheresis (ECP). This observation raises questions regarding the GVT in cutaneous neoplasms and potential immunomodulatory effects of ECP

<i>Pseudomonas aeruginosa</i> Cytotoxins: Mechanisms of Cytotoxicity and Impact on Inflammatory Responses

Pseudomonas aeruginosa is one of the most virulent opportunistic Gram-negative bacterial pathogens in humans. It causes many acute and chronic infections with morbidity and mortality rates as high as 40%. P. aeruginosa owes its pathogenic versatility to a large arsenal of cell-associated and secreted virulence factors which enable this pathogen to colonize various niches within hosts and protect it from host innate immune defenses. Induction of cytotoxicity in target host cells is a major virulence strategy for P. aeruginosa during the course of infection. P. aeruginosa has invested heavily in this strategy, as manifested by a plethora of cytotoxins that can induce various forms of cell death in target host cells. In this review, we provide an in-depth review of P. aeruginosa cytotoxins based on their mechanisms of cytotoxicity and the possible consequences of their cytotoxicity on host immune responses

Forehead Reconstruction with Microvascular Flaps: Utility of Aesthetic Subunits

Background Current literature describes the forehead as one aesthetic subunit of the face. We argue for the usefulness of aesthetic forehead subunits when microvascular flap reconstruction is required. Key to utilization of microvascular flaps for restoration of forehead subunits is an understanding of the patient population and defect characteristics most amiable to treatment. Methods We conducted an International Review Board-approved retrospective chart review of nine consecutive patients who had undergone free flap reconstruction for large forehead defects. Results The patients' foreheads included one paramedian defect; one central and paramedian defect; four central, paramedian, and lateral defects; and three lateral defects. Seven patients had ulnar forearm flaps and two had anterolateral thigh flaps. The success rate was 100%. Conclusion A forehead subunit classification system has been devised that provides a suitable option for cases that benefit from distant tissue replacement in a single stage, while preserving the principles of aesthetic replacement
