Neuroendoscopic and histopathological correlation in 13 cases of cystic fluid filled brain tumours.

Neuroendoscopical images of fluid-filled cavity walls within encephalic tumours in thirteen adult patients were correlated with histopathology results of samples harvested during surgery. Extensive vascular proliferation, with mesh-like formations in a 3D pattern, as well as onionskin appearance, were observed in malignant tumours, as opposed to normal or slightly increased vascular pattern, observed in benign neoplasms. Medical facilities lacking sufficient technical resources where limited pathologist experience is expected, and can be associated with intraoperative histological misdiagnosis.

Mexican Cervical Cancer Screening Study II: 6-month and 2-year follow-up of HR-HPV women treated with cryotherapy in a low-resource setting.

Objective: To determine the efficacy and tolerance of cryotherapy in a visual inspection with acetic acid (VIA) triage protocol after primary human papillomavirus (HPV) screening in a low-resource setting.

Materials And Methods: This continuous series conducted over 2 years enrolled nonpregnant, high-risk HPV (HR-HPV)-positive women between the ages of 30 and 50 years, who resided in the state of Michoacán, Mexico, and had a history of no Pap smear screening or knowledge of Pap smear results within the last 3 years. These women were initially enrolled in the Mexican Cervical Cancer Screening Study II (MECCS II) trial and were treated with cryotherapy after VIA triage.

Primary cervical cancer screening and triage using an mRNA human papillomavirus assay and visual inspection.

Objective: Mexican Cervical Cancer Screening Study II (MECCS II) seeks to develop a highly sensitive and highly specific screening program able to be adapted to all socioeconomic levels in Mexico. The objectives of MECCS II are (1) to compare the sensitivity and specificity for cervical intraepithelial neoplasia (CIN) 3 or cancer of self-collected vaginal specimens tested for high-risk types of the human papillomavirus (HR-HPV) by APTIMA with those tested for HR-HPV by Hybrid Capture 2 (HC2); and (2) determine the efficacy of cryotherapy in the treatment of HR-HPV-positive and acetic acid-aided visual inspection (VIA)-positive and -negative women after VIA triage.

Methods: The study was conducted in rural Mexico.

Endoscopic evidence of ventricular and cisternal inflammatory changes after intraoperative cysticercal rupture during endoscopic third-ventriculostomy removal.

Two patients who suffered recurrent hydrocephalus after cysticercal removal by means of endoscopic transventricular (ETV) approach are presented. Severe inflammatory lesions within the ventricular system and basal cisterns, with a patent third-ventriculostomy were demonstrated during a second endoscopic observation. Mandatory shunting with prolonged steroid therapy may be indicated after intraoperative cysticercal rupture after ETV removal, as showed by sequential endoscopic observations.

Cisternal neurocysticercosis.

Endoscopic third-ventriculostomy followed by removal of multiple cisternal cysts was performed in a patient with hydrocephalus secondary to cisternal cysticercosis. Adjuvant pharmacological therapy with cystocidal drugs and steroids, was administered in the postoperative period.
