RESUMEN
Ovarian angiosarcoma (OA) is rare, with only sporadic cases reported in English literature. We performed a systematic review of cases published in the PubMed, Science Direct, and Google Scholar databases with the aim of describing the reported clinicopathological features of OA. Fifty-three articles that reported 60 patients were reviewed. Of the 60 patients, 7 (11.6 %) were diagnosed with secondary (metastatic) ovarian angiosarcoma and 53 (88.3 %) were diagnosed with primary ovarian angiosarcoma. The mean age at presentation for ovarian angiosarcoma was 38.3±17.8 years. The average tumor size for ovarian angiosarcoma was 11.9±6.1 cm. Abdominal distention was reported in 45/60 (75 %). Microscopic examination revealed necrosis in 28/60 (46.7 %), pleomorphism in 32/59 (54.2 %), mitotic figures in 44/60 (73.3 %), spindle-shaped cells in 27/36 (75 %), epithelioid-shaped cells in 20/36 (55.5 %), and mixed epithelioid and spindle-shaped cells in 12/36 (33.3 %) patients. On immunohistochemistry CD 31 was positive in 41/41 (100 %), CD 34 in 38/39 (97.4 %), and Factor VIII related antigen in 18/21 (85.7 %) patients. Metastasis was present in 43/60 (71.6 %) patients. Chemotherapy and surgery was performed in 36/52 (69.2 %). The median follow-up time for ovarian angiosarcoma was 7 months (IQR1-IQR3:2-13.5 months). 24 (48 %) of the 50 patients with available survival data were alive and 26/50 (52 %) were dead of disease. Survival analyses (KM curves) revealed that the presence of necrosis (log-rank test; p = 0.05) and absence of spindle-shaped cells (log rank test; p = 0.04) on histopathology were associated with worse outcomes, while treatment with combined chemotherapy and surgical excision was associated with better survival (P < 0.001) therefore, prompt diagnosis and early treatment with combined chemotherapy and surgical excision can prolong survival in OA.
RESUMEN
OBJECTIVE: We conducted a systematic review and meta-analysis to evaluate the fetomaternal outcomes after the administration of norepinephrine or phenylephrine for the treatment of post spinal hypotension in preeclamptic women undergoing a cesarean section. DATA SOURCES: We searched on PubMed, Embase, Scopus, Cochrane CENTRAL, and clinicaltrials.gov from inception till June 2024. STUDY SELECTION: Randomized controlled trials of preeclamptic women receiving norepinephrine or phenylephrine for post spinal hypotension were included. DATA EXTRACTION AND SYNTHESIS: Two reviewers extracted data onto an Excel spreadsheet. R version 4.4 was used for statistical analysis. Risk ratios (RR) and their 95% confidence intervals (CIs) were calculated and pooled using the random effects model. Cochrane's risk of bias (RoB 2) tool was used for quality assessment. This review has been registered with PROSPERO (CRD42024532740). RESULTS: A total of 4 trials, comprising 413 participants, were included in this review. 206 patients received norepinephrine, while 207 received phenylephrine. The incidence of maternal bradycardia was significantly lower in the norepinephrine group compared with the phenylephrine group (RR = 0.25, 95 % CI = 0.16 to 0.39, p < 0.01). There were no statistical differences in other maternal outcomes or in the umbilical artery and umbilical vein blood gas analysis values. We also analyzed adverse events such as nausea (RR = 1.00, 95 % CI: 0.62 to 1.60, p = 1.00) and vomiting (RR = 0.99, 95 % CI: 0.89 to 1.11, p = 0.61), but they did not show a significant association with any group. All the trials had a moderate or low risk of bias. CONCLUSION: Bolus doses of NE and PE for the treatment of post-spinal hypotension in preeclamptic women undergoing cesarean sections were found to exhibit comparable neonatal outcomes. However, NE provided superior maternal safety due to a lower incidence of bradycardia compared to PE.
RESUMEN
The present systematic review aimed to identify all the available literature on awake craniotomy (AC) in patients with arteriovenous malformation (AVM) in order to evaluate its safety, risks, benefits and effectiveness. All available literature on AC in patients with AVM was collected and evaluated in an aim to provide a better understanding of its safety, associated risks and benefits. A systematic search for studies employing AC in patients with AVM was conducted using the PubMed, Scopus and ScienceDirect databases without restrictions on the year of publication, language, or study design, from inception up to May 30, 2021. A total of 11 studies published between 2004 and 2021 with 106 patients who underwent ACs were considered eligible. The rate of complete resection was 93% [95% confidence interval (CI), 82 to 100%; I2 0%]. The intraoperative complication rate was 21% (95% CI, 1 to 41%; I2 55%) and the post-operative complication rate was 33% (95% CI, 19 to 48%; I2 40%). During follow-up, the complication rate was 6% (95% CI, 1 to 10%; I2 30%). The post-operative complication rate was higher in the Spetzler-Martin grade (SMG) III-V group (31%; 95% CI, 21 to 42%; I2 46%) than in the SMG I-II group (12%; 95% CI, 2 to 22%; I2 0%). Similarly, the follow-up complication rate was higher in the SMG III-V group (9%; 95% CI, 2 to 16%; I2 34%) than in the SMG I-II group (0%; 95% CI, 0 to 4%; I2 0%). On the whole, the present study provides preliminary evidence to indicate that AC is a possible and useful option for the resection of AVM in selected patients. Well-designed future studies with long-term follow-up are required however, to investigate various aspects of safety and provide solid data for AC in patients with AVM.
RESUMEN
A disorder known as portal venous thrombosis (PVT) is characterized by a partial or total obstruction of the portal vein. Although PVT is somewhat uncommon, liver illness is frequently linked to it. Cirrhosis, carcinoma of the liver, myeloproliferative neoplasms, other malignancies, the use of oral contraceptives, intestinal infections, and genetic hypercoagulable illnesses are typical risk factors. In this case report, we discuss the case of a young male patient who had PVT as a result of a protein C deficit. The patient first had abdominal distention due to ascites, and the diagnosis of portal vein thrombosis was later confirmed by a triphasic computed tomography (CT) scan and Doppler ultrasonography. Anticoagulant medications were successfully administered to treat the patient. The importance of identifying PVT in patients with hypercoagulable diseases and the efficacy of anticoagulant therapy in such circumstances are both highlighted by this case.
RESUMEN
In recent decades, there has been a marked increase in the prevalence of thyroid cancer. This phenomenon has paralleled the increase in the prevalence of obesity worldwide, which is associated with insulin resistance. Associations between these entities have been hypothesized, mainly for older and female populations, but they remain unclear. The aim of this article is to systematically review the literature in an attempt to determine whether the increase in the prevalence of thyroid cancer is due to obesity or due only to improved detection with the better imaging techniques available. A thorough literature search on PubMed and application of selection criteria identified 15 appropriate studies. The detailed analysis of the data from these studies indicated that there is a suggestive association between thyroid cancer, obesity, insulin resistance and hyperinsulinemia for both genders. Therefore, the increased prevalence of thyroid cancer is not dependent on improved detection only. Further research should be performed for complete understanding of the pathophysiological associations, especially regarding adipose tissue and genetics, but also for the improvement of preventive public health policies.
