Viral dynamics in patients with monkeypox infection: a prospective cohort study in Spain.

Background: Monkeypox DNA has been detected in skin lesions, saliva, oropharynx, urine, semen, and stool of patients infected during the 2022 clade IIb outbreak; however, the viral dynamics within these compartments remain unknown. We aimed to characterise the viral load kinetics over time in various parts of the body.

Methods: This was an observational, prospective, multicentre study of outpatients diagnosed with monkeypox in two hospitals and two sexual health clinics in Spain between June 28, 2022, and Sept 22, 2022.

Evaluating the Accuracy of Self-Collected Swabs for the Diagnosis of Mpox.

We evaluated the accuracy of patient-collected skin lesions, oropharyngeal, and rectal swabs among 50 individuals enrolled in a study of mpox viral dynamics. We found that the performance of self-collected samples was similar to that of physician-collected samples, suggesting that self-sampling is a reliable strategy for diagnosing mpox.

Clinical presentation and virological assessment of confirmed human monkeypox virus cases in Spain: a prospective observational cohort study.

Background: In May, 2022, several European countries reported autochthonous cases of monkeypox, which rapidly spread globally. Early reports suggest atypical presentations. We aimed to investigate clinical and virological characteristics of cases of human monkeypox in Spain.

Picosecond 755-nm alexandrite laser treatment for oral lentiginosis in Peutz-Jeghers disease.

We present the case of a 16-year-old boy with Peutz-Jeghers disease with successful treatment of oral lentiginosis with one session of picosecond 755-nm alexandrite laser. To date, only in one other article picosecond laser is used for lentiginosis in Peutz-Jeghers disease. Other therapeutical options include Q-switched 755-nm alexandrite, 1064-nm Nd:YAG, 532-nm KTP-laser, ruby and intense pulsed light, which generally require more sessions, are less pigment-selective and have overall worse results than picosecond laser treatment.

Conradi-Hünermann-Happle syndrome with minimal signs.

A 4-year-old girl presented with congenital patches of scalp alopecia, which on physical examination, was consistent with blaschkolinear alopecic patches with mild epidermal atrophy. Similar atrophic hypopigmented patches were seen on the trunk and proximal extremities. With the clinical suspicion of Conradi-Hünermann-Happle syndrome, genetic testing was performed and revealed a mutation in the EBP gene.
