Celulitis necrosante estéril en las extremidades de migrantes marinos tras travesías prolongadas / Sterile necrotizing cellulitis in boat immigrants’ limbs after long journeys across the ocean

Fundamento Las Islas Canarias reciben migrantes de origen subsahariano que llegan a la costa tras largas travesías marinas en condiciones adversas. El «pie de patera» es una entidad previamente descrita consistente en un cuadro clínico desarrollado a partir de heridas en los pies que se infectan por estar en contacto con aguas fecales estancadas en el fondo de estas embarcaciones. Describimos un nuevo cuadro clínico, hasta ahora no publicado, consistente en un edema masivo de las extremidades que asocia necrosis de la piel y del tejido celular subcutáneo, respeta el músculo y su etiología no es de origen infeccioso. Material y métodos Diseñamos un estudio descriptivo observacional entre los meses de septiembre del año 2020 y enero del año 2022, ambos incluidos, en el ámbito del hospital de tercer nivel situado en Gran Canaria. Se incluyeron un total de 86 pacientes en una base de datos donde se analizaron 39 variables cualitativas y cuantitativas. Resultados Un total de 16 pacientes desarrollaron el cuadro consistente en una celulitis necrosante estéril. Su fisiopatogenia difiere de la del pie de patera, ya que en todos los casos los cultivos resultan estériles. Conclusiones Como mecanismo responsable, postulamos una teoría inflamatoria derivada del efecto osmótico de la ingesta de agua de mar y/o la reposición agresiva de fluidos a su llegada a los centros hospitalarios donde ingresan con deshidrataciones hipernatrémicas graves. El tratamiento quirúrgico precoz consiste en evacuar el edema mediante incisiones tipo escarotomías, el cual alivia la sintomatología y previene la progresión del cuadro (AU)

Background In the past few years, the Canary Islands received immigrants from sub-Saharan countries that arrive to the coast after long boat trips in extreme adverse conditions. The named «trench foot» is a previously described infectious entity developed after feet wounds that get infected by being in contact with water, urine and excrements in these small and crowded boats. We describe a new clinical entity, not published yet, that consists in massive edema in the extremities associating necrosis of the skin and subcutaneous tissue that characteristically respects the muscle and with a non-infectious etiology. Material and methods A database including 86 patients arrived by boat («patera») from sub-Saharan countries from September 2020 to January 2022 was made and 39 qualitative and quantitative items were analyzed. The Research Unit performed an observational prospective statistical analysis. Results A total of 16 patients developed the entity described as necrotizing cellulitis. Its physiopathology completely differs from the one described in the trench foot, since all the cultures resulted sterile. Conclusions We postulate an inflammatory theory due to the osmotic effect from ingesting sea water and/or the aggressive fluid reposition when they arrive to the emergency room with severe dehydration and hypernatremia. Early surgical evacuation of the edema with escharotomies incisions alleviate the symptoms and prevents progression of the disorder (AU)

Insights Into the Pathophysiology of Cellulite: A Review.

BACKGROUND: The etiology of cellulite is unclear. Treatment of cellulite has targeted adipose tissue, dermis, and fibrous septae with varying degrees of success and durability of response. OBJECTIVE: Results from clinical trials that target different anatomical aspects of cellulite can provide insights into the underlying pathophysiology of cellulite. MATERIALS AND METHODS: A search of the PubMed database and ClinicalTrials.gov website was conducted to identify clinical trials that have investigated treatments for cellulite. RESULTS: A lack of trial protocol standardization, objective means for quantification of improvement and reported cellulite severity, and short-term follow-up, as well as variation in assessment methods have made comparisons among efficacy studies challenging. However, the lack of durable efficacy and inconsistency seen in clinical results suggest that dermal or adipose tissue changes are not the primary etiologies of cellulite. Clinical studies targeting the collagen-rich fibrous septae in cellulite dimples through mechanical, surgical, or enzymatic approaches suggest that targeting fibrous septae is the strategy most likely to provide durable improvement of skin topography and the appearance of cellulite. CONCLUSION: The etiology of cellulite has not been completely elucidated. However, there is compelling clinical evidence that fibrous septae play a central role in the pathophysiology of cellulite.

Cellulite: Patient Selection and Combination Treatments for Optimal Results-A Review and Our Experience.

BACKGROUND: More than 90% of women have reported concerns of cellulite on their skin. Both commercially advertised creams and topical pharmacological agents have shown limited improvement. Thus far, there has been a paucity of thorough review articles on how to address and treat this condition. OBJECTIVE: To investigate how the etiology and pathogenesis of cellulite can help guide treatment combinations and provide a more algorithmic approach to comprehensively address a condition that affects so many women. MATERIALS AND METHODS: A review of the literature surrounding treatment options for cellulite and the authors' experience in this area are provided. CONCLUSION: This review summarizes available treatment options for cellulite, including topical agents, controlled subcision, energy-based devices, dermal fillers, and new injectable medications. Furthermore, the various ways that these treatments can be combined in an algorithmic and sequential approach based on the degree of volume loss, skin laxity, and excess adiposity associated with cellulite are addressed. These combination therapies for cellulite are supported both in the published literature and the authors' experience to help clinicians tailor a comprehensive treatment plan for the multiple factors that contribute to cellulite. Further clinical trials are needed to compare various devices and techniques for cellulite as well as combination treatments.

Structural Gender Dimorphism and the Biomechanics of the Gluteal Subcutaneous Tissue: Implications for the Pathophysiology of Cellulite.

BACKGROUND: This study was performed to investigate gender differences in gluteal subcutaneous architecture and biomechanics to better understand the pathophysiology underlying the mattress-like appearance of cellulite. METHODS: Ten male and 10 female body donors [mean age, 76 ± 16.47 years (range, 36 to 92 years); mean body mass index, 25.27 ± 6.24 kg/m (range, 16.69 to 40.76 kg/m)] were used to generate full-thickness longitudinal and transverse gluteal slices. In the superficial and deep fatty layers, fat lobule number, height, and width were investigated. The force needed to cause septal breakage between the dermis and superficial fascia was measured using biomechanical testing. RESULTS: Increased age was significantly related to decreased dermal thickness, independent of sex (OR, 0.997, 95 percent CI, 0.996 to 0.998; p < 0.0001). The mean number of subdermal fat lobules was significantly higher in male body donors (10.05 ± 2.3) than in female body donors (7.51 ± 2.7; p = 0.003), indicating more septal connections between the superficial fascia and dermis in men. Female sex and increased body mass index were associated with increased height of superficial fat lobules. The force needed to cause septal breakage in male body donors (38.46 ± 26.3 N) was significantly greater than in female body donors (23.26 ± 10.2 N; p = 0.021). CONCLUSIONS: The interplay of dermal support, septal morphology, and underlying fat architecture contributes to the biomechanical properties of the subdermal junction. This is influenced by sex, age, and body mass index. Cellulite can be understood as an imbalance between containment and extrusion forces at the subdermal junction; aged women with high body mass index have the greatest risk of developing (or worsening of) cellulite.

This approach aims to help clarify the pathogenesis of cellulite and provide a road map for developing effective treatment paradigms for patients.

Celulitis necrosante de la herida quirúrgica por candida albicans / Necrotizing cellulitis of the surgical wound by candida albicans

Las infecciones de la herida quirúrgica por Candida son muy infrecuentes. En una revisión de la literatura mundial de los últimos 10 años, realizada a través del MEDLINE, se encontraron sólo tres publicaciones con un total de 10 casos. En el trabajo describimos el caso de una paciente diabética con una infección de la herida quirúrgica por C. albicans, la cual tuvo la particularidad de manifestarse como una celulitis necrosante por Candida en la literatura revisada. La entidad probablemente debe ser incluida en el espectro de infecciones profundas que el hongo puede producir.
