PURPOSE Low- and middle-income countries (LMICs) experience the burden of 80% of new childhood cancer cases worldwide, with cure rates as low as 10% in some countries. Metronomics combines frequent administrations of low-dose chemotherapy with drug repurposing, which consists of using already-approved drugs for new medical applications. With wide availability, limited costs, and little infrastructure needs, metronomics can be part of constraint-adapted regimens in these resource-limited settings—with the understanding that metronomics shall not be a substitute for standard treatments when available and doable. Our study aims to describe the experience, practices, opinions, and needs in metronomics of physicians working in LMICs. METHODS An online questionnaire was sent to more than 1,200 physicians in pediatric oncology networks in LMICs. Items included the type of center, physician’s demographics, experience in pediatric oncology, and experience with current knowledge of metronomics. Opinions and perspectives were explored using multiple-answer and open questions. RESULTS Of physicians, 17% responded. Of respondents, 54.9% declared that they had already used a metronomic regimen. The most frequently cited repositioned drugs were celecoxib (44%) followed by propranolol and valproic acid (17%). Respondents highlighted the advantages of outpatient use (20%) and expected low toxicity (24%). In considering the drawbacks of metronomics, 47% of responses highlighted the lack of scientific evidence or guidelines, 33% the availability or affordability of drugs, and 18% the problem of acceptance or compliance. Of physicians, 79% believed that use of metronomics will spread in LMICs in the near future and 98% of them were willing to participate in international metronomic protocols or registries. CONCLUSION Metronomics is already used in LMICs and is a potential answer to unmet needs in pediatric oncology. There is room for improvement in the availability of drugs and a necessity to develop collaborative protocols and research to generate level A evidence.

Background: Generally, there are two methods for childbirth: normal vaginal and cesarean section (C-section). Each method has advantages and complications. In this study, we investigated the effects of type of delivery on hematological parameters in healthy full-term neonates in an Iranian population, from 2016-2017. Materials: Three hundred pregnant women, along with their healthy and term babies, were studied. According to the route of delivery, the neonates were divided into two groups: vaginal (n=150) and C-section (n=150). Complete blood count (CBC) and peripheral blood smear (PBS) were performed on the neonates from umbilical cord blood immediately after birth. Data were analyzed by using SPSS v. 22 and statistical analyses were done by student's t-test and correlation tests, with P-value < 0.05 set as the lowest limit of significance. Results: We observed a significant increase in hematologic parameters, such as red blood cell (RBC) count, hemoglobin, hematocrit, red cell distribution width (RDW), platelets, total leukocyte count and neutrophil count, in full-term neonates who delivered vaginally compared to those delivered by cesarean section (p<0.001). However, there was no significant difference between the delivery types in terms of mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), mean platelet volume (MPV), platelet distribution width (PDW), eosinophil count, lymphocyte count, or monocyte count. Conclusion: According to our study, the mode of delivery influences the hematological parameters in full-term neonates; thrombocytopenia and anemia in neonates were associated with cesarean section delivery. Thus, we recommend that pregnant women do not deliver by C-section unless in emergency situations.

Basidiobolomycosis is an unusual fungal skin infection that rarely involves the gastrointestinal tract. This study reported a 5-year-old boy with gastrointestinal basidiobolomycosis that had been misdiagnosed as gastrointestinal lymphoma. He was treated by surgical resection and a combination of posaconazole and amphotericin B deoxycholate with an acceptable response and no recurrence.

Background: To investigate the serum levels of 25(OH)D and minerals in adults and children with haemophilia A, and the possible association of these factors with Pediatric Haemophilia/Haemophilia Activities List (PedHAL/HAL), Haemophilia Joint Health Score (HJHS) and Haemophilia-specific quality of life (QoL) index this case-control study was conducted. Materials and Methods: Eighty five haemophilia A patients (HP) registered in Hemophilia Society of Lorestan province were recruited. Along with HP, sex and age matched healthy controls (HCs) were recruited. Linear regression was used to evaluate the possible relation between biochemical factors and other variables. One-way analysis of variance (ANOVA) was used to compare the biochemical factors between three or more independent groups. Results: Results indicated that serum zinc, phosphorus and magnesium were significantly lower, whereas, serum level of alkaline phosphatase (ALP) was statistically higher in HP compared with HCs. Other biochemical factors including calcium and parathyroid hormone (PTH) were not different between groups. Serum 25(OH) D was lower only in children with haemophilia and not in adults. Percentage of subjects who were vitamin D deficient was higher in HP vs. HCs (57.6% vs. 35.3%), and also this rate was higher in children with haemophilia vs. adults (77.8% vs. 48.3%). Lower serum concentrations of assessed minerals and vitamin D were associated with lower physical activity, poor QoL and worst joint health, and these associations were stronger in children. Conclusion: Present study indicated that serum levels of vitamin D and minerals were low in HP, and these low levels were associated with poor QoL, lower physical activity and worst joint health.

Aim: Favism is characterized as acute anemia, due to Glucose-6-phosphate dehydrogenase (G6PD) deficiency as a result of fava beans intake. It is associated with paleness, jaundice, and hemoglobinuria. In this study, signs, symptoms and therapeutic findings of the patients with hemolysis due to G6PD deficiency were investigated in Shahid Madani Hospital of Khorramabad, Lorestan. Methods: This is a single-center cross-sectional descriptive study that was conducted on all children with G6PD deficiencyinduced hemolysis. Results: 308 children (64.3% male and 35.7% female) were included in this study. The most common complaint was jaundice (82.5%) and the most common cause of hemolysis was the intake of fava bean (85.7%). 68% of the children were treated with hydration/fluid therapy. Blood transfusion was conducted in 36.36% of the cases and the mean of blood administered was 18.9 cc/kg. Conclusion: In this study, hydration therapy was performed in most of the children presenting favism. Also, the incorrect calculation of the amount of blood needed for transfusion has increased the frequency of blood transfusions and prolonged hospitalization time.
