Hypersensitivity reactions to metals in spine surgery.

Hypersensitivity to orthopedic devices is a rare condition with an underestimated incidence due to the lack of diagnostic guideline and ambiguous clinical manifestations. Although hypersensitivity to metal is common, a few cases of hypersensitivity reactions have been reported after spinal instrumentation. Spinal fusion and stabilization require a wide range of devices such as screws, wires, bands, and artificial disk replacement devices. Spinal instrumented surgeries are different from total joint arthroplasty in several aspects such as degree and pattern of motion, loading environment, and adjacent tissues with distinct characteristics. The interval for hypersensitivity reactions to occur after spinal metallic implantation is usually weeks to months. The present review covers the topic of hypersensitivity reactions that have been reported after spinal surgeries with the focus on cutaneous presentations.

Impact of COVID-19 Pandemic on Patients with Atopic Dermatitis / Impacto de la pandemia de COVID-19 en los pacientes con dermatitis atópica

Atopic dermatitis (AD) is a chronic skin disease that may be triggered by psychological conditions and several allergens. Patients with AD may be experienced disease exacerbation due to the COVID-19 pandemic lifestyle including home-quarantine and increased stress. We obtained the electronic data of 100 AD patients admitted to our hospital from 2016 to 2019 and called them with specific phone line.Out of 100 patients, 43 were male, and 57 were female (mean age±SD: 45.85±16.90). Sixty patients (37 females and 23males; mean age: 42.22±14.71) confronted disease flare-up during the COVID-19 era. Exacerbation of AD was correlated with treatment dose alteration, a lengthy history of atopic dermatitis, eczema duration, self-isolation, frequent handwashing, hand disinfection, and POEM scoring (P<0.05). Regarding the POEM scoring, 61 patients with moderate to severe AD experienced higher anxiety than 39 patients with silent to mild AD (P=0.013).In this study, most patients experienced disease exacerbation and perceived mild anxiety in this pandemic (AU)

La dermatitis atópica (DA) es una enfermedad cutánea crónica que puede desencadenarse debido a situaciones psicológicas y ciertos alérgenos. Los pacientes con DA pueden haber experimentado una exacerbación de la enfermedad debido al estilo de vida durante la pandemia de la COVID-19, incluyendo el confinamiento domiciliario y el incremento del estrés. Obtuvimos los datos electrónicos de 100 pacientes con DA ingresados en nuestro hospital de 2016 a 2019, y les llamamos con una línea telefónica específica.De los 100 pacientes, 43 eran varones y 57 mujeres (edad media ± DE: 45,85 ± 16,90), de los cuales 60 (37 mujeres y 23 varones, con edad media de 42,22 ± 14,71) experimentaron el brote de la enfermedad durante la etapa de la COVID-19. La exacerbación de la DA guardó relación con la alteración de la dosis de tratamiento, un largo historial de dermatitis atópica, la duración del eccema, el autoaislamiento, la frecuencia del lavado de manos, la desinfección de las manos, y la puntuación POEM (p < 0,05). En lo referente a dicha puntuación, los 61 pacientes con DA de moderada a grave experimentaron mayor ansiedad que los 39 pacientes con DA de silente a leve (p = 0,013).En este estudio muchos pacientes experimentaron exacerbación de la enfermedad y percibieron ansiedad leve durante la pandemia (AU)

Histopathological and immunohistochemical features of facial papules in frontal fibrosing alopecia.

BACKGROUND: Facial papules (FPs) are considered to be created by the inflammatory process, which involves facial vellus hairs, in frontal fibrosing alopecia. AIM: To demonstrate the histopathological features of FPs and the composition of the inflammatory infiltrate. METHODS: In total, 18 patients with FPs were enrolled in the study after histopathological confirmation of lichen planopilaris. Histopathological evaluation of the specimens was performed by two dermatopathologists. The samples were immunostained with CD4, CD8 and CD123 monoclonal antibodies, and the percentage and proportion of cells stained with these markers were investigated. RESULTS: A follicular lichenoid reaction and perifollicular fibrosis were present in all cases. Vellus hairs were detected in 83.3% of biopsy specimens (15 cases), all of which were involved by the inflammation. The majority of the follicles (72%) revealed follicular plugs. Reduction and destruction of elastic fibres were visible in the perifollicular (adventitial) and the papillary dermis (100% and 78% of specimens, respectively). Prominent sebaceous glands and dilated ducts were detected in 78% and 72% of samples, respectively. CD4-positive T cells formed 67.72% and CD8-positive T cells 32.28% of the infiltrate, and the mean CD4/CD8 ratio was 2.48. In 13 (72.2%) biopsy specimens < 10% of the infiltrate was positive for CD123 marker. CONCLUSIONS: Perifollicular inflammation, fibrosis and elastic-fibre destruction were constant histopathological features of FPs; furthermore, prominent sebaceous glands were present in the majority of samples. We also observed a CD4-positive predominance in the infiltrate.
