PURPOSE: to evaluate the spreading of endometrial cells to the peritoneal cavity during diagnostic hysteroscopy. METHODS: a prospective, descriptive study involving 76 patients divided in two groups: one with 61 patients without malignant endometrial cancer, and the other with 15 patients with endometrial cancer. Two samples of peritoneal fluid were collected, one before (PF-1) and the other immediately after (PF-2) the diagnostic hysteroscopy. Spread to the peritoneal cavity was defined by the presence of endometrial cells in PF-2, with the absence of such cells in PF-1. The 5 mm diameter Storz’s hysteroscopy was used. Distention was obtained by CO2 with electronically controlled flow pressure of 80 mmHg. The PF was fixated in absolute alcohol (ratio1:1). The PF samples were centrifuged and aliquots were smeared and stained using the Papanicolaou method. Analyses were performed by the same observer. RESULTS: during the study, four patients (5.26%) were excluded for presenting endometrial cells in PF-1. In the remaining 72 patients, there was no spread of cells to the peritoneal cavity. In the non-endometrial cancer group, 88.1% (52/59) presented secretory endometrial phase, with correlation of 80% between the hysteroscopy and the biopsy. In the group with endometrial cancer, most of the patients were in stage I (92.3%). There was a 100% correlation between the hysteroscopy/biopsy and histopathology of the surgical sample. CONCLUSIONS: the diagnostic hysteroscopy with CO2 at flow pressure of 80 mmHg did not cause spread of endometrial cells to the peritoneal cavity in both groups, thus suggesting that the diagnostic hysteroscopy is safe for patients at high risk for endometrial cancer.

PURPOSE: to evaluate the vascular blood flow of the central retinal arteries using dopplervelocimetry in the different phases of the ovulatory menstrual cycle. METHODS: we performed an observational, longitudinal and prospective study evaluating 34 healthy and ovulatory women. All women were submitted to Doppler scan of the eye to evaluate the vascular resistance of the central retinal arteries, either lying down or on a seated position, during four phases of the menstrual cycle. Confirmation of ovulation was performed by measuring serum progesterone during the luteal phase. We analyzed the pulsatility and resistance index and the maximum, minimum and mean velocity. RESULTS: mean age was 29.7 years. No differences were observed between the indexes obtained in both eyes, therefore a mean index was used for comparisons. As the comparison between the positions used for the exams showed a higher PI for the seated position, the analyses were performed separately. The pulsatility index in the lying position was different among the different phases of the menstrual cycle. The arterial resistance was significantly lower during the intermediate follicular and the periovulatory phases, as compared to the early follicular and luteal phases. When the comparison was performed with the patient in the seated position, no differences were observed. CONCLUSIONS: Our results demonstrate a reduction in the vascular resistance of the cerebral microcirculation and a posterior reversal, as shown by changes in the PI.
