Challenges in use of saliva for detection of SARS CoV-2 RNA in symptomatic outpatients.

Background: A major expansion in SARS CoV-2 testing is urgently needed. Saliva is an attractive option as an alternative for nasopharyngeal swabs (NPS), since saliva can be self-collected, is non-invasive, and sample quality is not dependent on the expertise of the collector.

Objective: To compare SARS CoV-2 positivity on paired NPS and saliva samples.

[Radiation-induced neurosarcoma. Clinical, histological and immunohistochemistry aspects].

The authors report on a case of radiation-induced malignant Triton tumor eg malignant schwannoma with rhabdomyoblastic differentiation). The tumor was situated in the brachial plexus of a patient who had received irradiation therapy 20 years previously for breast carcinoma. Pathological and immunohistological features have been described: coexpression of PS100, vimentin and desmin indicate a common neuroectodermic origin.

[Tubo-ovarian actinomycosis].

Pelvic actinomycosis is uncommon and usually represents a complication of an intrauterine device (IUD). This organism is very difficult to culture, and most actinomyces is actually identified by histologic features in pathologic specimens or by cytologic features on Papanicolaou smears. A specific fluorescent antibody stain is also available.

[The value of antibiotic prophylaxis during intrauterine procedures during vaginal delivery. A comparative study of 500 patients].

This comparative study carried out on 550 patients has made it possible for us to show how valuable prophylactic antibiotic therapy is when certain intra-uterine manipulations (such as forceps delivery, manual removal of the placenta or exploration of the cavity of the uterus) are carried out during vaginal delivery. Furthermore, we have been able to show that there are certain risk factors of which the most important are premature rupture of the membranes, infected liquor, birth weight of the infant less than 2,500 g and epidural analgesia. The financial study has shown that it is cheaper to use prophylactic antibiotics when the comparison is made with the cost of treating complications of infection associated with these intra-uterine procedures.

[Pre-eclampsia and the nephrotic syndrome. Prognosis and management; apropos of a series of 23 cases].

In pregnancy pre-eclampsia can be complicated by the nephrotic syndrome. We report on the clinical findings in 23 patients who had the nephrotic syndrome in pregnancy with hypertension. None of these patients had any previous sign of nephropathy.
