ABSTRACT

More than three and a half years have passed since the start of the coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and there have been several studies in the literature about the different damage and symptom patterns related to the condition; particular attention has been paid to the transmission of the disease from pregnant mothers to fetus. In this report, we present the case of a 36-year-old patient with a history of two cesarean sections (CS), two miscarriages, and hypothyroidism on replacement therapy, who contracted COVID-19 during the 15th week of gestation. Ultrasound (US) examination at 22 weeks revealed regular fetal biometry and bilateral ventriculomegaly, highly suggestive of massive intracerebral hemorrhage. The patient opted for the interruption of pregnancy. Given the critical maternal COVID-19 complications, especially tracheoesophageal fistula and the patient's two previous cesareans, we decided on an abortive CS at 23 weeks of gestation, and the samples were sent to the Pathology Department. Histologic analysis showed massive intervillous deposition of fibrin and inflammatory infiltration with hotspots of necrotic deciduitis and confirmed massive cerebral hemorrhage in the fetus. This morphological appearance was consistent with COVID-19 infection and probable fetal oxygenation compromise related to deciduitis. Immunoexpression of anti-SARS-CoV-2 S1 antibody was almost entirely positive at the level of syncytiotrophoblast cells and maternal leukocytes in the absence of a clear signal in the fetal circulation. Conversely, in the brain, immunoexpression of angiotensin-converting enzyme 2 (ACE2) and the S1 subunit of the spike protein of SARS-CoV-2, detected by a monoclonal antibody, was almost entirely negative, suggesting that there was no infection in the brain and that the massive intraventricular hemorrhage was probably a secondary effect of placental damage.

ABSTRACT

This is a monocentric and cross-sectional study conducted at the COVID-19 Division of the Obstetrical and Gynecological Unit and Intensive Care Units (ICUs) of Policlinico di Bari, in Bari, Italy, between September 2020 and April 2022. This study aimed to identify the prevalence of severe-critical COVID-19 illness requiring access to the Intensive Care Unit (ICU) among 287 pregnant patients, and possible correlations between the SARS-CoV-2 variants, the specific pandemic wave (dominated by wild, Alpha, Delta, and Omicron strains), and severe-critical adverse maternal outcomes. The prevalence of severe-critical COVID-19 illness was 2.8% (8/287), reaching 4.9% (8/163) excluding the 4th wave (Omicron dominant). The Delta variant determined the highest risk ratio and odds for access to the ICU due to severe-critical COVID-19-related symptoms compared to the other variants (wild, Alpha, Omicron). During the third wave (Delta), the ICU cases underwent a higher rate of hyperimmune plasma infusion (75%), antibiotic therapy (75%), and remdesivir (33%); all of the patients were intubated. During the Omicron wave, the patients were asymptomatic or with few symptoms: most of them (70%) were vaccinated with a median of two doses. The maternal outcome worsened in the case of Alpha and, especially, Delta variants for severe-critical COVID-19-related symptoms and ICU access.

ABSTRACT

Malignant melanoma is a fatal disease that affects all skin sites. Among these, vulvar melanoma (VM) is a rare gynecological condition that accounts for 5% of all vulvar neoplasms. VM primarily affects older Caucasian women and its relationship to sun exposure is undefined. Diagnosis is defined by biopsy but many clinical, dermatoscopic, and confocal microscopic features can guide doctors. The molecular profile is characterized by the KIT mutation, revealed by all of the technologies that are used (classical sequencing, next-generation sequencing, and immunohistochemical staining). BRAF and NRAS mutations are also common in VM. All of these mutations are possible therapeutic targets. Today, surgery remains the first treatment choice for primary VM. The role of neoadjuvant and adjuvant therapy is scarce and the treatment of relapses is widely debated.
