Spontaneous abdominal bleeding associated with SARS-CoV-2 infection: causality or coincidence?

Authors present 6 cases of abdominal bleeding associated with COVID-19, representing 1.35% of all hospitalized COVID-19 patients and hypothesize that there could be, although not very frequently, a relationship between SARS-CoV2 and bleeding. They excluded a side effect of the low molecular weight heparin therapy that all patients underwent during the course of the disease or other possible causes. Alterations of the coagulation state or a weakness of the vascular wall due toa presumed endotheliitis SARS-CoV-2 infection induced, are hypothesized by the authors. Investigation and follow-up for possible hemorrhagic problems in patients with COVID-19 is recommended. In particular, clinicians should be vigilant about retroperitoneal hemorrhage in COVID-19 patients. In addition to the fact that these patients are being treated with anticoagulants, anemia and abdominal pain are the signs that should lead us to suspect this type of haemorrhage. More studies are needed to understand if COVID-19 can be directly associated with bleeding. (www.actabiomedica.it)

Meningitis with cranial polyneuritis and cavernous sinus thrombosis by Borrelia crocidurae: First autochthonous case in Europe.

Borrelia crocidurae is endemic in West Africa, where it represents the leading cause of tick-borne relapsing fever (TBRF). TBRF typically presents with high fever and systemic symptoms, followed by recurrent episodes. Neurological complications may occur during febrile relapses. B. crocidurae is considered the most neurotropic agent of TBRF and is associated to severe neurological manifestations i.e. meningitis and encephalitis. To date, European cases of B. crocidurae infection have been reported in travelers returning from endemic areas. We report the first autochthonous case in Europe of B. crocidurae infection, presenting as meningitis with cranial polyneuritis and cavernous sinus thrombosis that were not preceded by classic febrile recurrences.

Non-primary nail-plate syphilis in an HIV-infected patient.

A 37-year-old Caucasian male, HIV-infected (CDC A2) in 2012 and on antiretroviral therapy, presented for a follow-up visit. On physical examination, a barely discernible light-colored macular rash was observed on the trunk, not involving the palms and soles. However, clear maculo-papular lesions were present over the proximal volar aspect of both forearms. Furthermore, well-demarked purplish, opaque, rough, vertically ridged plaque-like lesions were observed over the proximal portions of fingernails. The patient reported that cutaneous and nail lesions had appeared about 2 months prior and that he had engaged in unprotected sex 5 months before. Serologic tests for syphilis resulted reactive. Intramuscular injection of benzathine penicillin G, 2.4 million units, was administered once a week for 3 weeks. One month after therapy, the rash was no longer present, and at 5 months, nail abnormalities had disappeared. The clinical findings, the serologic results, and the disappearance of skin and nail lesions after the administration of penicillin strongly suggest that this HIV-infected patient had secondary or early late syphilis with skin and nail-plate involvement. We are experiencing a resurgence of syphilis as well as an increase in unusual and/or forgotten clinical manifestations. Syphilis remains a diagnostically challenging disease.
