Left Ventricular Non-compaction in a 40-Year-Old Male With Congenital Hydrocephalus.

Left ventricular non-compaction (LVNC) is a rare type of cardiomyopathy resulting from ineffective embryogenesis and is typically recognized shortly after birth. Here, we report a case of LVNC in a 40-year-old male with a history of congenital hydrocephalus who presented in overt heart failure. To date, there have been few reported cases of LVNC associated with hydrocephalus in the pediatric population and the pathophysiology is poorly understood. This nonclassical presentation of LVNC illustrates a rare cause of heart failure that may be related to hydrocephalus. Recognition of LVNC and further elucidating its association with hydrocephalus is crucial for identifying risk factors of LVNC and preventing its progression to heart failure.

Role of daratumumab in relapsed or refractory multiple myeloma patient: A meta-analysis and literature to review.

Introduction: With an increase in number of cases of relapsed or refractory multiple myeloma (RRMM), scientist have discovered various combination of medications among which one is daratumumab, Daratumumab is a mono-clonal antibody which attacks CD-38 markers present in abundance on the surface of myeloma cells and is used universally for the treatment of primary newly diagnosed multiple myeloma patients. Methods and Methodology: This meta-analysis was conducted according to Cochrane Collaboration guidelines in which initially 679 articles were evaluated for relevance on abstract level followed by full text screening of final list of 45 articles. Out of the 45 articles, only 10 articles qualified for selection criteria for eligibility. Three Phase 3 randomized control clinical trials which includes primary outcomes of progression free span and secondary outcomes including complete response, partial response or very good partial response and adverse effects reported were included in this study. Results: A total of three studies including 1533 patients (849 in Daratumumab treatment group while 684 patients in control group) were included in the study. All three of these studies were phase 3 clinical trial conducted to observe the role of daratumumab in relapsed and refractory multiple myeloma. Mean age reported was 65 years in both treatment and control groups. This study showed that daratumumab improves primary and secondary outcomes including progression free span, overall response rate, very good partial response, and complete response. However, daratumumab increases drug induced adverse effects. Conclusion: Our study confirmed that daratumumab in combination therapy improved primary and secondary outcomes when compared with platinum-based chemotherapy, but more adverse effects were reported in the combination group. So, we recommend that combination therapy should include daratumumab in treatment of relapsed and refractory multiple myeloma patients.

Clinicopathologic Features and Survival Outcomes of Signet Ring Cell Carcinoma of the Appendix: An Analysis of the Surveillance, Epidemiology, and End Results Database.

Background and objective Signet ring cell carcinoma of the appendix (SRCCA) is an exceedingly rare tumor, and very limited data are available regarding its characteristics and survival probabilities. Our objective in this study was to utilize the Surveillance, Epidemiology, and End Results (SEER) database to explore the patient and tumor characteristics and to characterize the three- and five-year cancer-specific survival (CSS) probabilities of SRCCA. Methods Patients with SRCCA diagnosed between 2000 and 2015 were analyzed using the SEER database. The three- and five-year CSS probabilities were estimated by the Kaplan-Meier method, and the groups were compared using log-rank comparisons and multivariable Cox hazard regression analysis. Results  A total of 527 patients were identified. The median age of the participants at diagnosis was 56 years, with a majority of them being female and white. Histologically, 60% of the tumors were high grade, and 61.3 % of the tumors were found to be metastatic on presentation. Three- and five-year CSS probabilities were 39% and 18.4%, respectively, and median survival was 26 months. Best survival outcomes were noted in males (five-year CSS: 25.4%, p=0.027), unmarried patients (five-year CSS: 19.1%, p=0.042), tumors <2 cm in size (five-year CSS: 50.5%, p<0.001), and low-grade tumors (five-year CSS: 44.8%, p<0.001). Subtotal colectomy yielded better three- and five-year CSS probabilities compared to no surgery and partial colectomy (48.5% and 26.5%, respectively, p<0.001). On the multivariate analysis, it was found that age and stages T4, N1, and M1 were associated with an increased risk of mortality, while surgery, regardless of the extent, was a protective factor. Conclusion  SRCCA is a rare tumor with a high prevalence among old-aged white females. This tumor is usually diagnosed in an advanced stage and has a dismal prognosis. Surgical intervention, regardless of the extent, showed better survival probabilities compared to no surgery.
