We conducted a hospital-based case-control study to explore the association between proximity to various land use types and childhood leukemia and lymphoma. This research involved 428 cases of childhood leukemia and lymphoma (2016-2021), along with a control group of 428 children aged 1-15 in Tehran. We analyzed the risk of childhood cancer associated with land use by employing logistic regression adjusted for confounding factors such as parental smoking and family history. The odds ratio (OR) for children with leukemia and lymphoma residing within 100 m of the nearest highway was 1.87 (95% CI = 1.00-3.49) and 1.71 (95% CI = 1.00-2.93), respectively, in comparison to those living at a distance of 1000 m or more from a highway. The OR for leukemia with exposure to petrol stations within 100 m was 2.15 (95% CI = 1.00-4.63), and for lymphoma it was 1.09 (95% CI = 0.47-2.50). A significant association was observed near power lines (OR = 3.05; 95% CI = 0.97-9.55) within < 100 m for leukemia. However, no significant association was observed between power lines and the incidence of childhood lymphoma. There was no association between bus stations, major road class 2, and the incidence of childhood leukemia and lymphoma. In conclusion, our results suggest a possible association between the incidence of childhood leukemia and proximity to different urban land uses (i.e., highways and petrol stations). This study is the first step in understanding how urban land use affects childhood leukemia and lymphoma in Tehran. However, comprehensive studies considering individual-level data and specific pollutants are essential for a more nuanced understanding of these associations., (© 2024. The Author(s).)

A 17-month-old boy with a known case of T-cell acute lymphoblastic leukemia was admitted to the authors' hospital because of blood-streaked diarrhea a week after his last chemotherapy session. Initially, he was treated with supportive care and an empiric regimen for opportunistic causes of diarrhea; however, this was not effective. Eventually, evaluation of his stool with PCR showed positivity for cytomegalovirus. Consequently, he responded dramatically to treatment with ganciclovir. Although cytomegalovirus colitis is rare, a few case reports suggest cytomegalovirus as a possible cause of colitis in children with leukemia, which can be fatal and should be considered as a differential diagnosis.

Introduction: Medical advances have improved life expectancy and survival of patients with thalassemia. However, as getting older, patients with thalassemia experience different complications which impair their quality of life. The aim of this study was to examine the effects of a nurse-implemented orientation program on quality of life in patients with thalassemia. Methods: A convenience sample of 55 patients with thalassemia were recruited in this quasi-experimental study. Patients were randomly allocated to control or experimental groups. A demographic questionnaire, Thalassemia quality of life questionnaire, and 36-item short form health survey were used for data collection before and one month after the intervention. In the intervention group, 1.5-month orientation program including of the three steps of inauguration, implementation, and closure was implemented, while the control group received routine care. The Chi-square, independent t-test and paired-samples t-test were used for data analysis by using SPSS ver.13 software. Results: The intervention and control group did not differ significantly from each other regarding demographic characteristics. Moreover, no significant difference was observed between the two groups regarding the quality of life scores after the implementation of orientation program. Conclusion: Implementing a short-term orientation program was not effective in enhancing the quality of life in patients with thalassemia; hence, developing long-term multimodal strategies may result in better improvement.

Objectives: Perinatal asphyxia (PA) is very significant in perinatal medicine due to the involvement of the central nervous system. This study was conducted to investigate the biochemical, clinical, and paraclinical changes associated with phenobarbital administration in neonates with PA., Methods: In this prospective, case-control study, 30 neonates with PA in two groups of 15 each (case and control) were investigated. The case group received 20 mg/kg intravenous phenobarbital within six hours of birth, and the control group did not receive phenobarbital. Serum concentrations of nitric oxide (NO) were measured at enrollment and one week after birth in the two groups. Clinical, electroencephalography, and magnetic resonance imaging findings of the two groups were compared., Results: At enrollment, the two groups did not differ in clinical severity, seizure incidence, or NO concentration. After one week, NO concentration was significantly lower in the case group (p < 0.050), but there was no significant difference in other variables between the two groups., Conclusions: Early administration of phenobarbital in term neonates with PA could protect them against encephalopathy.

Introduction: Diaper dermatitis is referred to the inflammation in outer layers of the skin in the perineal area, lower abdomen, and inner thighs. The lesions are maculopapular and usually itchy, which could cause bacterial or candida infection, and predispose the infants to penis or vaginal and urinary infection and lead to discomfort, irritability, and restlessness. The drugs which have been so far administered for this disease (topical steroids) cause special complications for the sensitive skin in this area. Magnesium (Mg) is known for its anti-inflammatory and wound-healing properties., Aim: The aim of the present study was to study the effect of the cream containing Mg 2% on treatment of diaper dermatitis and diaper rash in children., Materials and Methods: In this clinical trial study, 64 children aged less than two years old with diaper dermatitis referring Paediatric Ward of Hajar Hospital were randomly assigned to two groups of 32. Group one was treated with the combined cream Mg 2% and Calendula and group two with Calendula cream alone. The duration of recovery was compared between the two groups., Results: The duration of recovery was significantly lower in the intervention group than the control group (p-value<0.001), but there was no significant difference in the lesions size and diapers' number between the two groups., Conclusion: Based on the finding of this study, Mg is effective on treatment of diaper dermatitis and could be used for treating diaper dermatitis and other types of dermatitis.

Background: Complications of Ventolin as the most common drug used for bronchiolitis are widely known. The present study was conducted to determine the efficacy of hypertonic saline 3%, compared with Ventolin, for treatment of acute bronchiolitis in children., Methods: This double-blinded clinical trial study was conducted in Hajar Hospital, Shahrekord, Iran, from 2011 to 2012. A total of 70 patients under the age of two years with bronchiolitis were divided into two groups of 35 each. Ventolin nebulizer and hypertonic saline 3% nebulizer three times per day were administered in the first (Ventolin) and second (Hypersaline) group, respectively. The length of recovery was compared between the two groups. The data were analyzed by SPSS software (version 22) using chi-square, t-test, paired t-test, and Mann-Whitney., Results: The mean±SD length of recovery was 4.14±0.9 and 3.06±0.6 in the Ventolin and hypersaline groups, respectively. The mean duration of recovery was significantly lower in the hypersaline group (p<0.001)., Conclusion: Hypertonic saline 3% nebulizer has more pleasant therapeutic effects on acute bronchiolitis than Ventolin. Therefore, use of hypertonic saline 3% nebulizer is recommended for the treatment of acute bronchiolitis in children under two years old.

Background: Understanding the possible role of visfatin in the pathogenesis of beta-thalassemia major (BTM) and its relationship with markers of endothelial function could help us to provide more effective therapeutic approaches for treatment of patients with BTM and its related complications. The aim of current study was to compare serum level of visfatin between patients with BTM and control group and determine its correlation with markers of endothelial function, intracellular adhesion molecule (ICAM) and vascular adhesion molecule (VCAM)., Methods: In this case-control study, patients with BTM receiving regular blood transfusion aged 10-20 years and a group of healthy subjects were enrolled. Selected subjects examined clinically and venous blood samples obtained for visfatin, ICAM, VCAM, cholesterol, triglyceride, high density lipoprotein cholesterol, low density lipoprotein cholesterol and ferritin measurements. Mean (standard deviation) of studied laboratory measurements compared in two studied groups and the relation between visfatin and ICAM, VCAM, ferrittin, body mass index determined., Results: In this study 31 patients with BTM and 30 healthy controls studied. Mean of visfatin was significantly higher in patients with BTM than control group (133.9 ± 60.1 vs. 43.3 ± 27.9, P < 0.001)., Conclusions: The higher level of visfatin among patients with BTM indicated the possible inflammatory role of this adipocytokine in BTM. It seems that for understanding the underlying mechanisms and its relation with vascular inflammatory markers and endothelial function further studies with larger sample size is needed.
