Endometriosis-related spontaneous hemoperitoneum in pregnancy: A case series.

Endometriosis can be associated with adverse pregnancy outcomes. We report six cases of endometriosis-related spontaneous hemoperitoneum diagnosed in pregnant and postpartum women over 13 years. Spontaneous hemoperitoneum in pregnancy mainly occurred in the second half of gestation. All women presented with acute abdominal pain; four of them needed an emergent surgery, two were managed expectantly. The median estimated blood loss was 4250 ml, four women required massive transfusion. Three out of six women had a known history of endometriosis, all of them had histologically confirmed endometriosis after surgery. No maternal or perinatal deaths occurred. In one case, reticence to perform a computed tomography scan led to delayed diagnosis. Since delay can lead to lethal consequences, high levels of suspicion for spontaneous hemoperitoneum should be maintained in cases of severe abdominal pain, even with a woman's negative history of endometriosis. Improved knowledge and regular interdisciplinary meetings are pivotal to ameliorate outcomes.

Histologic and metabolic assessment in a cohort of patients with genital prolapse: preoperative stage and recurrence investigations.

BACKGROUND: Biological basis of prolapse development and recurrence are still unclear. Aim of this observational and prospective study is to correlate clinical stage of anterior vaginal wall prolapse and anatomical recurrence to histological and metabolic characteristics of vaginal tissue. METHODS: Patients undergoing surgery were divided into two groups according to anterior stage ≤II (group A) and ≥III (group B). Full-thickness excisional biopsies of the anterior vaginal wall were obtained after hysterectomy. Hystological characteristics and metalloproteinases activity (MMP-2) were analyzed. RESULTS: Sixty-nine patients (35 group A; 34 group B) completed evaluation. Mean follow-up was 35 months. Collagen amount and organization were significantly higher in group B both in lamina propria and fascia specimens, but MMP-2 activity was significantly lower in this group. Recurrence rate of anterior compartment was 10.1%. Collagen cellularity of fascia was higher in recurrence groups. On the contrary MMP-2 activity showed a close to significant correlation to surgical success (P=0.07). CONCLUSIONS: Patients with advanced stages of prolapse have increased collagen amount associated to decreased MMP-2 activity. This suggests that connective tissue is more abundant but less metabolically active in patients with severe prolapse. A similar trend can be found in recurrences.

Treatment of simple and complex endometrial non-atypical hyperplasia with natural progesterone: response rate to different doses.

The aim of this study is to evaluate the response rate to natural progesterone in non-atypical endometrial hyperplasia and to identify the lowest effective dose. A total of 197 patients of childbearing age with simple or complex hyperplasia were retrospectively identified. The women were treated with a cyclic administration of progesterone at different dosages (100 versus 200 versus 300 mg daily). Endometrial biopsies were performed at 6, 12, 18 months. In comparing progesterone to a regimen of no therapy, a significantly higher remission rate was observed in the progesterone group than in the latter (95 versus 75%, p = 0.05 for simple hyperplasia; 89 versus 35%, p < 0.001 for complex hyperplasia). Out of 60 women with simple hyperplasia, remission was observed in 9/11 (81.8%), 40/41 (97.5%) and 8/8 (100%) patients treated, respectively, with progesterone 100, 200 and 300 mg daily. Out of 72 women with complex hyperplasia, remission was observed in 3/5 (60%), 49/53 (92.4%) and 12/14 (85.7%) patients treated with progesterone 100, 200 and 300 mg daily, respectively. There was no statistically significant difference in the response rate in the two groups, neither with simple nor with complex hyperplasia. In conclusion, progesterone increased the regression rate of both simple and complex hyperplasia.

Short-term preoperative IL-2 immunotherapy in operable pancreatic cancer: a randomized study.

BACKGROUND/AIMS: A cell-mediated immunodeficiency is demonstrated to occur in advanced cancer patients. Lymphocytopenia predicts a poor prognosis, moreover, the surgical trauma can worsen the impaired immune surveillance and favor disease recurrence. This study investigates the effectiveness of preoperative interleukin-2 administration to improve lymphocyte counts' postoperative recovery in pancreatic cancer. METHODOLOGY: 31 patients with pancreatic cancer who underwent radical surgery were randomized according to 3 different groups. Group A: 9 patients treated with human recombinant IL-2 subcutaneously at 9 million IU/day for 3 days before surgery; group B: 9 patients treated with IL-2 at 12 million IU/day for 3 days before surgery; group C: 13 patients treated with surgery alone. Assessment of total and T helper lymphocyte counts were studied at hospital admission and in 7th and 14th postoperative day. RESULTS: Toxicity of IL-2 treatment was mild in all groups. Postoperative lymphocytopenia was observed in group A and C, without statistical differences, whereas group B had mean lymphocyte levels within the normal values in the postoperative period. CONCLUSIONS: This preliminary result suggests that preoperative subcutaneously IL-2 immunotherapy at 12 million IU for 3 consecutive days before surgery is able to abrogate the effects of the surgical trauma and recover a normal immunofunction in pancreatic cancer patients.
