Stillbirth and Congenital Syphilis: Autopsy and Placental Findings of 11 Cases and Review of the Literature.

Syphilis is a preventable and treatable disease, which continues to strike low-income countries and vulnerable populations in high-income countries. It is caused by , a spirochete capable of traversing the placental barrier, with a high rate of fetal and placental infection. Congenital syphilis (CoS) has poor prognosis if left untreated.

Metastatic pituitary neuroendocrine neoplasms: A case report of a malignant prolactinoma.

We report a rare clinical case of a malignant prolactinoma in which the exponential increase of prolactin levels with minimal tumor growth and no response to treatment led to diagnosis of abdominal, thoracic, and vertebral metastases.

Disturbed by a sandfly: visceral leishmaniasis in ileal Crohn´s disease under combined immunosuppression.

This case reports illustrates a 44-year-old Caucasian male with ileal Crohn´s disease under combined immunosuppression that first presented with unspecific constitutional symptoms, newly pancytopenia and elevated inflammatory markers. The infectious screening was negative except for an ileal abscess that resolved with conservative antibiotic therapy. Due to concerns for lymphoproliferative disease in a patient under anti-TNF and azathioprine, a myelogram was performed that ruled out dysplastic changes.

Balance between maternal antiviral response and placental transfer of protection in gestational SARS-CoV-2 infection.

The intricate interplay between maternal immune response to SARS-CoV-2 and the transfer of protective factors to the fetus remains unclear. By analyzing mother-neonate dyads from second and third trimester SARS-CoV-2 infections, our study shows that neutralizing antibodies (NAbs) are infrequently detected in cord blood. We uncovered that this is due to impaired IgG-NAb placental transfer in symptomatic infection and to the predominance of maternal SARS-CoV-2 NAbs of the IgA and IgM isotypes, which are prevented from crossing the placenta.

Pituitary metastasis as the first manifestation of lung carcinoma.

Pituitary metastases are rare. Clinical presentation could range from asymptomatic to panhypopituitarism or local symptoms. We present a case report of a 43-year-old male patient with a new onset headache, visual disturbances, and panhypopituitarism.

Code of practice for medical autopsies: a minimum standard position paper for pathology departments performing medical (hospital) autopsies in adults.

The medical autopsy (also called hospital or clinical autopsy) is a highly specialised medical procedure, which requires professional expertise and suitably equipped facilities. To ensure high standards of performance, the Working Group of Autopsy Pathology of the European Society of Pathology (ESP) suggests a code of practice as a minimum standard for centres performing medical autopsies. The proposed standards exclusively address autopsies in adults, and not forensic autopsies, perinatal/or paediatric examinations.

Case report: Rare convexity meningeal chondroma mimicking a meningioma.

Background: Intracranial chondromas account for 0.2-0.3% of all intracranial neoplastic lesions and less than a quarter arise in the convexity or falx.

BD-2 and BD-3 increase skin flap survival in a model of ischemia and Pseudomonas aeruginosa infection.

The main aim of this work was to study the usefulness of human β-defensins 2 (BD-2) and 3 (BD-3), which are part of the innate immune system, in the treatment of infected ischemic skin flaps. We investigated the effect of transducing rat ischemic skin flaps with lentiviral vectors encoding human BD-2, BD-3, or both BD-2 and BD-3, to increase flap survival in the context of a P. aeruginosa infection associated with a foreign body.

Simultaneous Supratentorial and Infratentorial Pilocytic Astrocytomas in an Adult Patient with Concurrent Neurofibromatosis Type 1 and HIV Infection.

Background: Neurofibromatosis type 1 (NF1) has been identified as a predisposing factor in the development of pilocytic astrocytoma (PA), a common benign central nervous system tumor. Although this is a common association, simultaneous development of multiple lesions is an infrequent finding, especially in nonoptic and hypothalamic locations.

Case Description: A 41-year-old female patient with NF1 and uncontrolled human immunodeficiency virus (HIV) type 1 infection presented with a first generalized seizure and associated headache and ataxia.
