Pressurized intraperitoneal aerosol chemotherapy (PIPAC) with cisplatin and doxorubicin in patients with ovarian cancer: A systematic review.

BACKGROUND: PIPAC consists in delivering normothermic chemotherapy solution directly into the peritoneal cavity as an aerosol under pressure. Currently PIPAC is considered as a palliative treatment for patients suffering from non-resectable peritoneal carcinomatosis. We performed a SR to assess tolerance and response of this novel method among patient with OC. METHODS: We searched electronic database PubMed, Embase, Web of Science, Clinical Trials.gov. We only included clinical studies reporting PIPAC with cisplatin and doxorubicin in patients with ovarian cancer. RESULTS: This systematic review included 4 studies. In 3 studies all patients were pretreated with cytoreductive surgery, in 1 study surgery was performed in 8/34 (23 %) patients. Mean PCI at first PIPAC procedure ranged from 16.3 to 19.6. All studies reported the proportion of patients with ascites at the first PIPAC with a pooled rate of 48,3 %. Pooled rate of CTCAE Grade 3 toxicity calculated on the total number of PIPAC was 6 % and Grade 4 was 0.9 %. One study reported two cases of small bowel perforation related or potentially related to PIPAC. On study reported a cumulative survival after 400 days of 62 % and a mean actuarial survival time of all patients who underwent PIPAC of 442 days. In another study the mean time to progression was 144 days (95 % CI 122-168 days). CONCLUSION: This systematic review demonstrated that PIPAC with cisplatin and doxorubicin appear to have a good safety profile with low toxicity and encouraging trend in terms of overall survival.

Serous Cystic Neoplasms of the Pancreas Management in the Real-world: Still Operating on a Benign Entity.

OBJECTIVE: Our aim is to provide a real-life picture of serous cystic neoplasms (SCNs) management once a presumptive diagnosis is made. SUMMARY OF BACKGROUND DATA: SCNs of the pancreas are invariably benign entities. While consensus about their management is lacking, surgical resection still plays a role. METHODS: Presumed SCNs evaluated from 1990 to 2018 were included. Indications for surgery, predictors of resection, rate, and predictors of misdiagnosis in the surgical cohort and time trends of management strategies were the main outcomes. RESULTS: A total of 672 presumed SCNs were included. Presence of symptoms (37%) and large size (34.1%) were the most frequent indications for surgery. Symptoms (60.4% vs 19.0%, P < 0.001), size (45 vs 30 mm, P < 0.001), solid components (19.7% vs 6.2%, P < 0.001), thick walls (14.4 vs 5.6%, P = 0.001) and main pancreatic duct dilation (13.4% vs 5.6%, P = 0.004) were associated with upfront resection (n = 134, 19.9%). Upfront resection decreased over time and 15.4% of patients eventually crossed over to surgery. Increase in size (6.9 vs 1.3 mm/yr), development of symptoms (25.3% vs 3.4%, P < 0.001), solid component (6.0% vs 1.4%, P = 0.010) or jaundice (3.6% vs 0.7%, P = 0.028) were associated with crossing over to surgery. Major morbidity and mortality occurred in 17.1% and 1.7% of patients, respectively. Misdiagnosis occurred mostly in case of macrocystic/unilocular lesions of the body-tail. CONCLUSIONS: In the real-life scenario, SCNs still represent an indication for surgery particularly once large and symptomatic. During surveillance, resection occurs mostly in younger individuals for body/tail lesions. Evidence-based consensus on appropriate indications for surgery is urgently needed.

Management of Transverse Vaginal Septum by Vaginoscopic Resection: Hymen Conservative Technique.

Transverse vaginal septum is a rare female genital tract anomaly, and little is described about its surgical treatment. We report the case of a patient who wished to preserve hymenal integrity due to social and cultural beliefs. We performed a vaginoscopic resection of the septum under laparoscopic view, followed by the introduction of a Foley catheter in the vagina, thus preserving the hymen. After 12 months of follow-up, no septal closure was present, and the menstrual flow was effective. Vaginoscopic hysteroscopy is an effective method of vaginal septum resection, even in cases in which hymenal integrity must be preserved due to social and cultural beliefs.

Septo vaginal transverso é uma anomalia rara do trato genital feminino, e pouco é descrito sobre o tratamento cirúrgico. Relatamos o caso de uma paciente que desejava preservar a integridade do hímen devido a crenças sociais e culturais. Realizamos ressecção vaginoscópica do septo sob visão laparoscópica, seguida da introdução de um cateter de Foley na vagina, preservando assim o hímen. Após 12 meses de acompanhamento, não havia fechamento do septo, e o fluxo menstrual era eficaz. A histeroscopia vaginoscópica é um método eficaz de ressecção dos septos vaginais, incluindo os casos em que a integridade do hímen deve ser mantida devido a crenças sociais e culturais.

Oxidative Stress and Endometriosis: A Systematic Review of the Literature.

Endometriosis is one of the most common gynaecologic diseases in women of reproductive age. It is characterized by the presence of endometrial tissue outside the uterine cavity. The women affected suffer from pelvic pain and infertility. The complex etiology is still unclear and it is based on three main theories: retrograde menstruation, coelomic metaplasia, and induction theory. Genetics and epigenetics also play a role in the development of endometriosis. Recent studies have put the attention on the role of oxidative stress, defined as an imbalance between reactive oxygen species (ROS) and antioxidants, which may be implicated in the pathophysiology of endometriosis causing a general inflammatory response in the peritoneal cavity. Reactive oxygen species are intermediaries produced by normal oxygen metabolism and are inflammatory mediators known to modulate cell proliferation and to have deleterious effects. A systematic review was performed in order to clarify the different roles of oxidative stress and its role in the development of endometriosis. Several issues have been investigated: iron metabolism, oxidative stress markers (in the serum, peritoneal fluid, follicular fluid, peritoneal environment, ovarian cortex, and eutopic and ectopic endometrial tissue), genes involved in oxidative stress, endometriosis-associated infertility, and cancer development.
