RESUMO

Multiple studies have reported immune thrombocytopenia (ITP) relapse following SARS-CoV-2 vaccination, however baseline ITP relapse rate and antibody response to vaccination are not known. Patients with ITP who received at least one of the first three SARS-CoV-2 vaccination doses were included in the study. One hundred and twenty-four patients met the inclusion criteria. Relapse rate was 4.2% following a first vaccine dose, 9.1% after a second and 2.9% after a third; baseline relapse rate was 7.6%. Ninety-four per cent of patients who received three vaccine doses developed a clinical antibody response. SARS-CoV-2 vaccination appears to be safe and effective in patients with ITP.

RESUMO

Management of symptoms and prevention of life-threatening hemorrhage in immune thrombocytopenia (ITP) must be balanced against adverse effects of therapies. Because current treatment guidelines based on platelet count are confounded by variable bleeding phenotypes, there is a need to identify new objective markers of disease severity for treatment stratification. In this cross-sectional prospective study of 49 patients with ITP and nadir platelet counts <30 × 109/L and 18 aged-matched healthy controls, we used susceptibility-weighted magnetic resonance imaging to detect cerebral microbleeds (CMBs) as a marker of occult hemorrhage. CMBs were detected using a semiautomated method and correlated with clinical metadata using multivariate regression analysis. No CMBs were detected in health controls. In contrast, lobar CMBs were identified in 43% (21 of 49) of patients with ITP; prevalence increased with decreasing nadir platelet count (0/4, ≥15 × 109/L; 2/9, 10-14 × 109/L; 4/11, 5-9 × 109/L; 15/25 <5 × 109/L) and was associated with longer disease duration (P = 7 × 10-6), lower nadir platelet count (P = .005), lower platelet count at time of neuroimaging (P = .029), and higher organ bleeding scores (P = .028). Mucosal and skin bleeding scores, number of previous treatments, age, and sex were not associated with CMBs. Occult cerebral microhemorrhage is common in patients with moderate to severe ITP. Strong associations with ITP duration may reflect CMB accrual over time or more refractory disease. Further longitudinal studies in children and adults will allow greater understanding of the natural history and clinical and prognostic significance of CMBs.

RESUMO

Choriocarcinoma coexisting with or after a "normal" pregnancy has an incidence of one per 160 000 pregnancies. In case of choriocarcinoma after term pregnancy, early diagnosis by histopathological examination of the placenta is very important, the precocity of the diagnosis influencing the prognosis and tumor response to chemotherapy. In this paper, we report the case of a 29-year-old woman gravidity 2, parity 2, with metastatic choriocarcinoma after term pregnancy, diagnosed at four months after the delivery of a healthy baby. An episode of abundant vaginal bleeding occurred after four months from delivery. The local exam revealed a vaginal tumor whose pathological examination on biopsy samples was inconclusive. Subsequently, she was admitted in our clinic with abundant vaginal bleeding, severe anemia and fever. Abdominal ultrasonography revealed an intracavitary uterine tumoral mass with signs of myometrial invasion to the uterine serosa, strong Doppler signal and moderate ascites. Pulmonary X-ray and computed tomography scan excluded extrapelvic tumoral masses. The pretreatment human chorionic gonadotropin (HCG) level was 31 030 IU÷mL and her FIGO risk factor score was 8 (high-risk group). Total hysterectomy with bilateral salpingo-oophorectomy and omentectomy was performed as an optimal cytoreduction. Postoperative remaining lesions were represented by the metastasis located in the lower two-thirds of the vagina. Histopathological examination revealed uterine choriocarcinoma with ovarian metastasis. Postoperative was initiated four courses of polychemotherapy. Case evolution was favorable, with the normalization of the ßHCG value in two months postoperative and complete remission of the vaginal metastasis in six weeks postoperative.

RESUMO

UNLABELLED: Endometriosis represents a chronic female genital tract disease characterized by implants outside the endometrial cavity, leading to alteration of pelvic anatomy and having as result chronic pelvic pain and infertility. AIM: From the molecular perspective, the aim of studying endometriosis is identifying a cause and a consequence, that lead to the appearance and perpetual arising of new implants. The description of the immunohistochemical (IHC) profile of ectopic endometrium could represent a new element in the pathogenesis of endometriosis and also a practical method to appreciate the aggressiveness and possibility of recurrence of the disease. The study consisting of histopathological and immunohistochemical (IHC) analysis of the tissues excised included 14 patients, operated from June to December 2014, to which was confirmed the presumptive diagnosis of endometriosis, based on anamnesis, clinical examination and ultrasound appearance. We identified the expression of estrogen and progesterone receptors, whose presence in the ectopic endometrium guides the medical hormone postoperative treatment. We also identified the expression of a cellular proliferation marker - Ki-67, and inhibition marker of cellular apoptosis - Bcl-2, in order to characterize the aggressiveness of endometriosis implantations and a stromal marker CD10. Although there are plenty of medical and surgical therapeutic methods available, the treatment of endometriosis must be individualized for every patient taking into consideration the IHC analysis. Consolidation of surgical treatment by prescription of a medical long-term treatment is indispensable, because endometriosis is a chronic relapsing disease.

RESUMO

UNLABELLED: A 37-year-old male has left exophthalmia, which gradually evolved in the last two years, finally with a deviation of left eye (LE), down side and out, with gradually decrease of visual acuity (VA). These symptoms are accompanied with headache and psychiatric manifestations with irritability, decreased attention, anxiety, insomnia, depressed mood. Brain Computed Tomography (CT) shows a tumor mass in air leakage sinus, bilateral frontal and bilateral ethmoidal, with left orbital invasion. This tumor mass lysis by pressure the supero-posterior wall of the left orbit, with the delimitation of a frontal epidural process with a capsule and calcifications. Additionally, it has been shown there is a bilateral maxillary sinusitis. The surgical intervention removed the infection focal spots rearranging the left eyeball, recovering the VA. The sinuses were drained. The psychiatric symptoms in the post operatory phase disappeared. Histopathological examination of the excised tissue revealed sinus ciliated respiratory mucosa with mixed acute and chronic inflammatory infiltrate and focal squamous metaplasia. The lamina propria is edematous and contains large numbers of neutrophils, lymphocytes and plasma cells. Histopathological diagnosis is acute and chronic sinusitis. CONCLUSIONS: An untreated infection of the aerial sinuses can lead to a complication like Pott's puffy tumor. When signs such as ophthalmologic, psychiatric and intense headaches appear, it suggests the presence of the Pott's puffy tumor (PPT). The clinical signs are reversible once the tumor has been removed.
