Progression of the systemic inflammatory response in patients with appendicitisIntroduction: The systemic inflammatory response has been described in patients with appendicitis. However, its progression from the onset of symptoms to diagnosis has not been characterized. The purpose of this study was to describe and characterize the systemic inflammatory response to appendicitis. Patients and Methods: A descriptive study was conducted. One-hundred eighty-three patients were studied divided into four groups from onset of symptoms to diagnosis. Primary outcome measure was to determine the systemic inflammatory response to appendicitis according to the established groups of time intervals. Secondary outcome measure was the analysis of C-reactive protein for the same purpose. Results: The systemic inflammatory response variables according to diagnostic intervals showed non-significant differences on white blood cells count. Temperature and heart rate rises constantly after 48 h reaching their peak after 72 h (p = 0.001); the respiratory rate rises after 73 h (p < 0.0001). After 73 h most patients had 3 or 4 systemic inflammatory response criteria (p < 0.0001). C-reactive protein levels rise progressively showing higher levels after 48 hours (p = 0.005). Conclusions: The inflammatory response to appendicitis is progressive, being more marked along the timeline from onset of symptoms to diagnosis.
Majorlin's ulcer arising in burn scar: surgical managementWe discuss the case of a 63-years-old woman presenting with Majorlin's ulcer over the popliteal area. This localization is the most frequent for this lesion. We review the diagnosis, epidemiology, and aggressive surgical treatment with wide excision of the ulcer and repair with fasciocutaneous flap.Key words: Majorlin's ulcer, squamous cell carcinoma, malignant degeneration of burn scar. ResumenSe presenta un caso de úlcera de Majorlin en la región poplítea de una paciente de 63 años de edad. Esta localización es la más frecuente de esta lesión. Se discute su diagnóstico, epidemiología, etiología y tratamiento agresivo con resección amplia de la ulcera y reparación con un colgajo fasciocutáneo.Palabras clave: Úlcera de Majorlin, carcinoma espinocelular, degeneración maligna de quemadura. CASO CLÍNICO IntroducciónLa malignización de las cicatrices crónicas, principalmente de las cicatrices por quemaduras, es un fenómeno conocido 1-3 . La incidencia de degeneración maligna de estas cicatrices es de aproximadamente 2% y varía entre 1,2% y 9% 1,4 . El carcinoma espinocelular es la neoplasia que se observa con mayor frecuencia (75% a 96%), seguida del carcinoma basocelular (1% a 25%). Otras neoplasias infrecuentemente descritas son el melanoma, sarcoma, liposarcoma, fibrosarcoma, carcinosarcoma y la coexistencia de melanoma con carcinoma espinocelular y fibrohistiocitoma 1,2 . El desarrollo de carcinoma en cicatrices por quemaduras se asocia a quemaduras extensas y profundas que cicatrizan por segunda intención; por esta razón se insiste en el manejo de estas lesiones con injertos o colgajos evitando la cicatrización por segunda intención 1,2,4,5 . La degeneración maligna de estas cicatrices o período de latencia tumoral, se relaciona inversamente con la edad en la cual el sujeto sufrió la quemadura; así, cuando la lesión se produce en pacientes más jóvenes el período de
