RESUMO

Background: A complete uterine septum, double cervix and vaginal septum is a complex and rare congenital genital tract anomaly. The diagnosis is often challenging and based on the combination of different diagnostic techniques and multiple treatment steps. Objective: To propose a combined one-stop diagnosis and an ultrasound-guided endoscopic treatment of complete uterine septum, double cervix, and longitudinal vaginal septum anomaly. Materials and Methods: Stepwise demonstration with narrated video footage of an integrated approach management of a complete uterine septum, double cervix and vaginal longitudinal septum treated by expert operators combining minimally invasive hysteroscopy and ultrasound. The patient was 30 years old and was referred to our clinic because of dyspareunia, infertility and the suspicion of a genital malformation. Results: A one-stop complete evaluation of uterine cavity, external profile, cervix, and vagina was made through 2D, and 3D ultrasound combined with hysteroscopic assessment and a U2bC2V1 malformation (according to ESHRE/ESGE classification) was diagnosed. The procedure consisted in a totally endoscopic removal of the vaginal longitudinal septum and the complete uterine septum, starting the uterine septum incision from the isthmic level, and sparing the two cervices, under transabdominal ultrasound guidance. The ambulatory procedure was performed in the Digital Hysteroscopic Clinic (DHC) CLASS Hysteroscopy in Fondazione Policlinico Gemelli IRCCS of Rome - Italy, under general anaesthesia (laryngeal mask). Main outcomes: Surgical time of procedure was 37 minutes; no complications occurred; patient was discharged three hours after the procedure; the hysteroscopic office control after 40 days showed a normal vagina and a normal uterine cavity with two normal cervices. Conclusion: An integrated ultrasound and hysteroscopic approach allows an accurate one-stop diagnosis and a totally endoscopic treatment option for complex congenital malformations using an ambulatory model of care with optimal surgical results.

RESUMO

Purpose ofInvestigation: Solid ovarian tumors represent a clinical challenge, in particular in case of young patients who require a fertility sparing treatment. The authors report a case of hypercellular mitotically active ovarian fibrothecoma in a very young woman, successfully treated with a fertility sparing surgery. MATERIALS AND METHODS: A 21-year-old nulliparous woman presented at the present hospital with a 14-cm right ovarian mass, consisting of solid and pseudo-cystic components. There was neither an elevation of tumor markers nor evidence of metastatic disease. A laparotomic right salpingo-oophorectomy was performed. Uterus and left adnexa were preserved. RESULTS: The neoplasm consisted of a prevalent population of spindle-shaped elements and of a minor component of cells with wider cytoplasms, attributable to a thecomatous differentiation. The mitotic activity was focally elevated. Cytological atypia was mild to focally moderate. Clear areas of coagulative necrosis were not observed. At present 48 months after surgery, the patient is alive with no evidence of recurrence. CONCLUSIONS: The authors reported the lesion as a hypercellular and mitotically active fibrothecoma. The uneventful follow-up confirms the low malignant potential of the lesion. Caution is required reporting hypercellular stromal ovarian tu- mors, in order to avoid overdiagnosis and overtreatment, particularly in young patients.

RESUMO

Thrombotic disease is one of the most relevant clinical problems for morbility and mortality. We can differentiate congenital and acquired forms. In this short communication we describe 1 case observed by us that seems interesting for the association of a congenital and acquired form [Protein S deficiency and inflammatory bowel disease (IBD)] and for the dramatic events suffered before receiving a complete diagnosis and therapy, indicating the importance of recollection of information from the patients, starting from anamnestic data.

RESUMO

We studied the innate and adaptive immune system of rhesus macaques infected with the virulent simian immunodeficiency virus isolate SIVmac251 by evaluating natural killer (NK) cell activity, cytokine levels in plasma, humoral and virological parameters, and changes in the activation markers CD25 (interleukin 2R ¿IL-2R alpha chain), CD69 (early activation marker), and CD154 (CD40 ligand) in lymphoid cells. We found that infection with SIVmac251 induced the sequential production of interferon-alpha/beta (IFN-alpha/beta), IL-18, and IL-12. IFN-gamma, IL-4, and granulocyte-macrophage colony-stimulating factor were undetected in plasma by the assays used. NK cell activity peaked at 1 to 2 weeks postinfection and paralleled changes in viral loads. Maximum expression of CD69 on CD3(-)CD16(+) lymphocytes correlated with NK cytotoxicity during this period. CD25 expression, which is associated with proliferation, was static or slightly down-regulated in CD4(+) T cells from both peripheral blood (PB) and lymph nodes (LN). CD69, which is normally present in LN CD4(+) T cells and absent in peripheral blood leukocyte (PBL) CD4(+) T cells, was down-regulated in LN CD4(+) T cells and up-regulated in PBL CD4(+) T cells immediately after infection. CD8(+) T cells increased CD69 but not CD25 expression, indicating the activation of this cellular subset in PB and LN. Finally, CD154 was transiently up-regulated in PBL CD4(+) T cells but not in LN CD4(+) T cells. Levels of antibodies to SIV Gag and Env did not correlate with the level of activation of CD154, a critical costimulatory molecule for T-cell-dependent immunity. In summary, we present the first documented evidence that the innate immune system of rhesus macaques recognizes SIV infection by sequential production of proinflammatory cytokines and transient activation of NK cytotoxic activity. Additionally, pathogenic SIV induces drastic changes in the level of activation markers on T cells from different anatomic compartments. These changes involve activation in the absence of proliferation, indicating that activation-induced cell death may cause some of the reported increase in lymphocyte turnover during SIV infection.

RESUMO

Mutations in the gene encoding the amyloid protein precursor (APP) cause autosomal dominant Alzheimer's disease. Cleavage of APP by unidentified proteases, referred to as beta- and gamma-secretases, generates the amyloid beta-peptide, the main component of the amyloid plaques found in Alzheimer's disease patients. The disease-causing mutations flank the protease cleavage sites in APP and facilitate its cleavage. Here we identify a new membrane-bound aspartyl protease (Asp2) with beta-secretase activity. The Asp2 gene is expressed widely in brain and other tissues. Decreasing the expression of Asp2 in cells reduces amyloid beta-peptide production and blocks the accumulation of the carboxy-terminal APP fragment that is created by beta-secretase cleavage. Solubilized Asp2 protein cleaves a synthetic APP peptide substrate at the beta-secretase site, and the rate of cleavage is increased tenfold by a mutation associated with early-onset Alzheimer's disease in Sweden. Thus, Asp2 is a new protein target for drugs that are designed to block the production of amyloid beta-peptide peptide and the consequent formation of amyloid plaque in Alzheimer's disease.

RESUMO

With the increasing use and success of BMT, larger numbers of children survive transplantation. Still, cancer treatment in children causes damage to the endocrine glands, often inducing growth deficiency, pubertal delay and thyroid dysfunction. This paper will deal with some of the most common endocrine disorders related to BMT in the pediatric population. Irradiation is the major contributor for growth impairment after BMT, acting through lesion to epiphyseal growth-plate, gonadal damage with delayed or precocious puberty, hypothyroidism, and growth hormone insufficiency. Gonadal dysfunction can be induced both by a direct injury to the gonads (irradiation, gonadotoxic agents) causing primary hypergonadotropic-hypogonadism, and with less frequency, by neuroendocrine injury to the hypothalamo-pituitary axis causing hypogonadotropic-hypogonadism. It seems that both doses of chemotherapy and of irradiation used by different regimens, fractionation of irradiation, and age at the time of BMT are the most important factors when we deal with toxic endocrine late-effects in long term survivors. In order to improve the quality of life of each single patient who receive BMT, and without inflicting the success-rate of this procedure, we recommend a life-long surveillance to prevent or to treat symptoms and disorders caused by hormone deficiencies, and we also advocate for a multidisciplinary team-approach that includes an endocrinologist consultant.
