RESUMO
This study was designed to determine the prevalence and type of malaria cases that presented throughout the year 2014 in a tertiary care hospital in Karachi, Pakistan. A total of 1099 cases, (377 females, 722 males) were reported. Plasmodium vivax (P. vivax) was discovered in 93.7% cases compared to 6.3% Plasmodium falciparum (P. falciparum). Based on the highest and lowest weather temperatures, in summer (June, July and August) and in winter (December, January and February) were differentiated. The number of cases were greater during summer months compared to winter. Interestingly, the ratio of P. falciparum to P. vivax during winter was greater compared to summer. Finally, there was a strong correlation between increasing humidity and number of malaria cases. These findings show that even though the incidence of malaria is higher in summer, malaria cases are still reported in winter. Furthermore, the probability of finding P. falciparum (which causes cerebral malaria ) is higher in winter.

INTRODUCTION: COVID-19 pandemic has resulted in a strong impact on students' wellbeing, with associated uncertainty about the future. We conducted a cross-sectional survey to assess the psychological effects of COVID-19 on the medical education of final year students in Pakistan. METHODS: We conducted prospective, cross-sectional survey, as a snapshot, from June 07, 2020 till June 16, 2020, among final year medical and dental students. The 20-questions survey questionnaire was based on rating-scale items to focus on psychological symptoms, institutional preparedness for such crisis and confidence in becoming a future doctor. Descriptive statistics were calculated using Multivariate regression analysis. RESULTS: Majority of participants (nâ¯=â¯1753/2661, 65.9%) were female. Despite timely closure of institutes, delay in the start of the online teaching (beta coefficient 0.08, P-value 0.02) was significantly correlated with the depressive symptoms. A significant percentage of students (nâ¯=â¯1594, 59.9%) wanted a delay in exit exams due to intimidation. A similar proportion of students also lost confidence to be a competent doctor in future which was positively associated with male gender (beta coefficient 0.21, P-valueâ¯<â¯0.001). CONCLUSION: Our study shows that COVID-19 pandemic has brought significant psychological influence on the medical education of final year students. Despite a stressful crisis, final year medical and dental students are still willing to serve the community. In addition to supporting their emotions and psychological wellbeing, stress counselling, and transforming current medical curricula is crucial to pursue ceaseless medical education and to become a safe future doctor.
RESUMO
Autoimmune hemolytic anemia (AIHA) is a form of hemolytic anemia in which red cells lysis occurs due to presence of an autoantibody. Association of AIHA is well known with lymphoproliferative disorders, especially with non-Hodgkin's lymphoma. However, AIHA in association with Hodgkin's lymphoma is seen occasionally. Of the AIHA associated with Hodgkin's lymphoma, most are of warm type or mixed type. Cold AIHA, as seen in our case, is very rare in Hodgkin's lymphoma.
