Ultrasonographic Subclinical Signs of Inflammation of the Lacrimal, Parotid, and Submandibular Glands in Users of Cosmetic Fillers.

OBJECTIVES: To detect ultrasonographic inflammatory signs in the lacrimal, parotid, and submandibular glands in cosmetic fillers (CFs) users. METHODS: A prospective and cross-sectional ultrasound study of the glands in cases with CFs was performed. The sample included users of hyaluronic acid, silicone oil, polymethylmethacrylate, polycaprolactone, calcium hydroxyapatite, and polyacrylamide. Abnormalities of the parenchyma and hypervascularity signs of the glands were compared with a control group (n = 10), evaluated by 2 observers, and correlated with the type, number, and location of the facial CFs. Cohen's kappa test and logistic regression models with odds ratios (OR) adjusted by age with 95% CI were performed. RESULTS: Sixty-three patients with CFs met the criteria. Parotid and submandibular glands had the highest percentage of parenchymal involvement: 87.3 and 88.9%, respectively (p <.01). Abnormalities of the echostructure of the parenchyma and hypervascularity of the glands were detected with all kinds of fillers without significant differences per type. A significant substantial interrater kappa (0.61) with an agreement of 90% for all glands among observers was found. CONCLUSION: Users of common types of CFs frequently present subclinical ultrasonographic signs of inflammation of the lacrimal, parotid, and submandibular glands. Further research on the topic seems necessary.

[Finasteride adverse effects: An update]. / Efectos adversos de finasteride: mitos y realidades. Una revisión actualizada.

Finasteride is a 5-α reductase inhibitor that is widely used in the management of benign prostate hyperplasia and male pattern hair loss. It is well known that these agents improve the quality of life in men suffering from these conditions. However, they are associated with some transient and even permanent adverse effects. The aim of this article is to clarify the controversies about the safety of finasteride by analyzing the evidence available in the literature.

Low effectiveness of methotrexate in the management of localised scleroderma (morphea) based on an ultrasound activity score.

BACKGROUND: The effectiveness of methotrexate (MTX), a first-line treatment for localised scleroderma (morphea), has not been assessed using colour Doppler ultrasonography (CDU). OBJECTIVES: We aimed to ultrasonographically monitor disease activity in patients with morphea treated with MTX, assessing its effectiveness using an Ultrasound Morphea Activity Score (US-MAS). MATERIALS & METHODS: A retrospective cohort of 22 patients was studied between July 2014 and July 2019. The morphea of each patient, treated with MTX, was confirmed by histology and all patients had at least two CDU examinations. The US-MAS is based on published ultrasound signs of disease activity validated by histology. A weight-adjusted average MTX dose (mg/kg/wk) was used to standardize dosage, weight, and time between CDU examinations. The difference in US-MAS between two CDU examinations was determined. Statistical analyses included Wilcoxon and Fisher exact tests, the Spearman correlation coefficient, and risk ratios with 95% confidence intervals. To create two groups, we determined the median of the sample as the cut-off point for MTX dose (0.265 mg/kg/week). Significance was set at p≤0.05; Results: In all cases, CDU examinations showed subclinical signs of activity beyond the visible lesional borders, either in the same or adjacent corporal segments. A negative correlation was found between the change in US-MAS and MTX dose (Spearman coefficient, -0.45; p = 0.035). The group dosed at ≥0.265 mg/kg/wk showed a non-significant change in US-MAS (2-point decrease). No case became inactive. CONCLUSION: MTX is a treatment with a low effectiveness for morphea, causing only slight decreases in ultrasound activity at higher doses.

Autoimmune progesterone dermatitis manifesting as generalized fixed drug eruption.

Autoimmune progesterone dermatitis is an uncommon, poorly recognized and under-diagnosed catamenial dermatosis associated with hypersensitivity reactions to progestagens. Most cases manifest as urticaria, eczema or erythema multiforme-like. A 26-year-old woman developed violaceous plaques on the groin and abdomen, 4 days after a spontaneous abortion resolved with uterine curettage. The lesions recurred once monthly at the same sites, mimicking a fixed drug eruption. Although the histopathology was compatible with fixed drug eruption, positive intradermal testing and symptomatic improvement after using oral contraceptive pills gave us a clue to the diagnosis.

Concomitant poroma and porocarcinoma.

Eccrine poromas and porocarcinomas are adnexal tumors derived from the sweat duct epithelium. However, eccrine poroma is benign in nature, whilst eccrine porocarcinoma is regarded as its malignant counterpart. We report the case of a man who presented simultaneously with an eccrine poroma and eccrine porocarcinoma. Both lesions had no clear distinctive features, enhancing the need of high-level clinical suspicion together with surgical excision and histopathology for prompt diagnosis confirmation.

[Ecthyma gangrenosum caused by Staphylococcus aureus]. / Ectima gangrenoso secundario a Staphylococcus aureus.

Ecthyma gangrenosum is an uncommon necrotizing vasculitis, in most cases secondary to sepsis by Pseudo-mona aeruginosa in immunocompromised patients. However, there have been several reports of ecthyma gangre-nosum caused by other infectious etiologies. We report an unusual case of ecthyma gangrenosum associated with methicillin-resistant Staphylococcus aureus infection in a patient without the classic immunological risk factors described in the literature.

[Acute generalized exanthematous pustulosis associated with Mycoplasma pneumoniae infection: a case report]. / Pustulosis exantemática generalizada aguda asociada a Mycoplasma pneumoniae: reporte de un caso.

Acute generalized exanthematous pustulosis is an uncommon skin eruption, characterized by fever and the rapid onset of disseminated, non-follicular, sterile pustules, over an erythematous skin background. It is usually classified as a severe cutaneous adverse drug reaction, whose most relevant triggers are antibiotics and anticonvulsants. However, viral and bacterial infections have also rarely been associated with this dermatosis. We report the case of a patient, who developed lesions of acute generalized exanthematous pustulosis as an extrapulmonary manifestation of Mycoplasma pneumoniae infection.

Exostosis subungueal y su diagnóstico diferencial: A propósito de un caso / Subungual exostosis and its differential diagnosis: A case report

Los tumores y pseudotumores ungueales representan un desafío diagnóstico, principalmente, dada la compleja anatomía de la uña y la apariencia clínica similar de estas lesiones. La exostosis subungueal es una entidad de baja frecuencia que debe considerarse en el diagnóstico de las masas subungueales. No es un tumor verdadero, sino crecimiento anormal de hueso o una calcificación de tejido cartilaginoso. En el siguiente artículo, se comunica el caso de una exostosis subungueal y realizamos una breve discusión, enfatizando los diagnósticos diferenciales, principalmente el melanoma subungueal, que debe sospecharse siempre y derivarse en forma precoz.(AU)

Nail tumors and pseudotumors represent a diagnostic challenge, mainly due to the complex anatomy of the nail and similar clinical appearance of these lesions. Subungual exostosis is an entity of low frequency, which should be considered in the differential diagnoses of subungual masses. It is not a true tumor, but an overgrowth of bone or cartilage tissue calcification. In the following article, we report the case of a subungual exostosis and perform a brief discussion, emphasizing the differential diagnoses, including the subungual melanoma, which should always be suspected and referred in a timely manner.(AU)
