Abstract
Introduction Studies described an increased frequency of hypertensive disorders of pregnancy (HDP) after a COVID-19 episode. There is limited evidence about SARS-CoV-2 viral load in placenta. This study aimed to investigate the relationship between SARS-CoV-2 viral load in the placenta and clinical development of HDP after COVID-19 throughout different periods of gestation. Methods This is a case-control study in women with and without gestational hypertensive disorders after SARS-CoV-2 infection diagnosed by RT-PCR during pregnancy. Patients were matched by gestational age at the moment of COVID-19 diagnosis. We performed an analysis of SARS-CoV-2 RNA levels in placenta. Results A total of 28 women were enrolled. Sixteen patients were diagnosed with COVID-19 during the third trimester and the remaining 12 patients in the other trimesters. Ten placentas (35.7%) were positive for SARS-CoV-2, 9 of them (9/14, 64.3%) belonged to the HDP group versus 1 (1/14, 7.2%) in the control group (p = 0.009). Those cases with the highest loads of viral RNA developed severe preeclampsia (PE). Conclusion Among women diagnosed with COVID-19 during pregnancy, the presence of SARS-CoV-2 in the placenta was more frequent among women suffering from PE or gestational hypertension. Furthermore, the most severe cases of HDP were associated with high placental viral load, not necessarily associated with a positive nasopharyngeal RT-PCR at delivery. Our data suggest that SARS-CoV-2 infection during pregnancy could trigger gestational hypertensive disorders through persistent placental infection and resulting placental damage.

Abstract
Dermatophytes are a group of closely related fungi that have the capacity to invade keratinized tissue (skin, hair, and nails) of humans and animals to produce an infection, dermatophytosis, commonly referred to as ringworm. Dermatophytoses are common of world wide: in the United States, Microsporum audouinii and Microsporum canis, once the major agents of tinea capitis, have been superseded by Trichophyton tonsurans. Since the 1950s, T. tonsuranshas advanced from Mexico and the Caribbean and is now the prevalent cause of tinea capitisin North America. M. canisis the prevalent agent of tinea capitis in many regions of the world, including Spain, at this moment. This could be related to close association of humans with their pets. M. canis is more prevalent in urban areas and Trichophyton mentagrophytes in rural ones. The superficial dermatophyte infections of the skin do not represent a single disease, their clinical appearance is dependent largely on the region of the body affected. There are more antifungal preparations available today than at any other time in medical history. Oral antifungals are indicated or required to treat hyperkeratotic areas such as nails, palms, soles and tinea capitis, patients with disabling or extensive disease, patients intolerant to or who have failed topical therapy, tose with chronic infection, those with granulomatous lesions and patients immunosuppressed by disease or by therapy. A successfull eradication of the fungi is now possible with relatively short treatment regimens.
