[Yellow nail syndrome. A case report with postmortem study].

Yellow nail syndrome is a rare disease of unknown aetiology. Patients with YNS have a characteristic yellowish-coloured nails, pulmonary alterations and primary lymphedema. To the best of our knowledge, only a few reports of autopsy findings in these patients have been published.

Treatment of COVID-19 during the Acute Phase in Hospitalized Patients Decreases Post-Acute Sequelae of COVID-19.

Background: The post-acute sequelae of SARS-CoV-2 (PASC) infection have caused a significant impact on our health system, but there is limited evidence of approved drugs focused on its prevention. Our objective was to identify risk factors that can determine the presence of PASC, with special attention to the treatment received in the acute phase, and to describe the profile of persistent symptoms in a multidisciplinary Post-Coronavirus Disease-19 (COVID-19) Unit.

Methods: This one-year prospective observational study included patients following an acute COVID-19 infection, irrespective of whether they required hospital admission.

Monkeypox outbreak in Spain: clinical and epidemiological findings in a prospective cross-sectional study of 185 cases.

Background: Since May 2022, a new outbreak of monkeypox has been reported in several countries, including Spain. The clinical and epidemiological characteristics of the cases in this outbreak may differ from those in earlier reports.

Objectives: To document the clinical and epidemiological characteristics of cases of monkeypox in the current outbreak.

Wound infection by Pantoea agglomerans after penetrating plant injury.

Pantoea agglomerans is a ubiquitous gram-negative bacterium that has been linked to skin and joint infections secondary to plant injuries. Herein we report a 58-year-old woman who presented with 2 erythematous nodules with purulent discharge on the anterior aspect of the right leg that developed after a penetrating plant injury. The patient was initially treated with amoxicillin-clavulanic acid, cloxacillin and clindamycin without improvement.

Diagnostic usefulness of immunohistochemical evaluation of CD1a antigen and polyclonal anti-leishmania antibodies in cutaneous leishmaniasis.

Background: Different immunohistochemical markers to detect amastigotes in cutaneous leishmaniasis have been proposed with variable diagnostic usefulness.

Objectives: To evaluate the diagnostic usefulness of immunohistochemical amastigotes identification by specific polyclonal anti-Leishmania antibodies and CD1a expression (clone EP3622) in a series of PCR confirmed cutaneous leishmaniasis.

Materials And Methods: Thirty-three skin samples corresponding to PCR confirmed cutaneous leishmaniasis were included in the study.

Sexually transmitted infections in young people and factors associated with HIV coinfection: an observational study in a large city.

Objectives: Young people are a critical target group for sexually transmitted infections (STI) surveillance due to their particular behavioural and social related vulnerability. The aim of this study was to describe the epidemiological characteristics and trends in the incidence of gonorrhoea, syphilis, HIV and venereal lymphogranuloma (LGV) among 15-24-year-olds in Barcelona, and to determine factors associated with HIV coinfection.

Design: We performed a population-based incidence study covering the 2007-2015 period.

Use of biological treatments in patients with hidradenitis suppurativa.

Pilosebaceous unit occlusion and secondary inflammatory perifollicular lympho-histiocytic infiltration seem to be the underlying etiopathogenic mechanisms giving rise to hidradenitis suppurativa (HS). Increased levels of tumor necrosis factor (TNF)-alpha and other cytokines such as interleukins 12 and 23 (IL12/23) and interleukins 10 and 17 have been observed in HS lesional skin. Biological drugs have been reported to be effective for HS, but the level and duration of the response are quite variable.

Pruritic nodular secondary syphilis in a 61-year-old man with HIV infection.

The typical finding in secondary syphilis stage is a generalized non-pruritic maculopapular eruption. We report a case of secondary syphilis in an HIV-infected patient presenting with pruritic crusted nodules showing numerous eosinophils on the histopathological examination.

Persistent cutaneous ulcers after Yttrium-90 synovectomy, an unusual complication: two case reports and a review of the literature.

Development of persistent deep cutaneous ulceration is a rare and serious complication of radiosynovectomy, an extended procedure used in the treatment of chronic synovitis. Cutaneous radiation necrosis is a rare complication of synovectomy, probably as a result of radiocolloid para-articular injection. This rare phenomenon should be suspected when an ulcer adjacent to an articulation appears several days or even months after a radiation synovectomy.

Persistent cutaneous abdominal ulcerations secondary to diffuse dermal angiomatosis: an underestimated sign for severe atherosclerosis: A case report.

Background: Diffuse dermal angiomatosis (DDA) is a rare, acquired, reactive vascular proliferation, clinically characterized by livedoid erythematous-violaceous plaques, which frequently evolve to ulceration and necrosis. Histopathologically, it is manifested by a diffuse proliferation of endothelial cells within the full thickness of the dermis. DDA has been mainly associated with severe peripheral atherosclerosis.
