Migraine-like headaches associated with nickel allergy requiring removal of atrial septal defect closure device

There is a deficit of literature regarding the association between nickel allergy–induced symptoms and implanted devices. This report describes a case of nickel allergy causing debilitating migraine-like symptoms, failing to resolve with medical therapy, requiring surgical removal of the device and repair of the defect.     

Recent advances in diagnosis and management of pulmonary hypertension in chronic lung disease

Pulmonary hypertension with elevated pulmonary vascular resistance is a common cardiovascular complication associated with increased morbidity and mortality in preterm infants with chronic lung disease. Injury to the developing pulmonary circulation results in structural and functional abnormalities of the pulmonary vasculature. Animal studies have demonstrated that disruption of angiogenesis may contribute to the failure of normal alveolarisation in chronic lung disease. Levels of vascular endothelial growth factor in bronchoalveolar lavage fluid are lower in infants with chronic lung disease compared to preterm controls. Supplemental oxygen is commonly used to prevent and treat pulmonary hypertension, although optimal arterial oxygen saturation levels remain uncertain. Other vasodilators such as inhaled nitric oxide appear promising, but as yet have not been evaluated in the form of randomised controlled trials. Further studies are required to investigate the long-term effectiveness of pulmonary vasodilator therapy.     

Role of leukotrienes in NSAID induced gastric ulceration and inflammation in wistar rats

ObjectiveTo evaluate the effects of Montelukast and Curcumin against indomethacin induced gastric damage in rats in order to assess the role of leukotriene (LTs) if any, in non steroidal anti-inflammatory drug (NSAID) induced gastroinflammation.MethodsThe effects of Montelukast (10 mg/kg) and Curcumin (100 mg/kg) were observed on gastric lesion induced by Indomethacin. The blood samples were analyzed for neutrophil adhesion and lipid peroxide levels in gastric tissue measured spectrophotometrically. The skin vascular permeability study was performed by using compound 48/80 induced vascular permeability model.ResultsMontelukast and Curcumin significantly reduced Indomethacin induced gastric lesion score. Pretreatment with Montelukast and Curcumin significantly counteracted Indomethacin induced gastropathy by a combination of its effect on inhibition of neutrophil adherence, through decrease in related production of free radicals that disrupts integrity of stomach mucosa and decrease in vascular permeability as compared to Indomethacin group. The results of the present study further indicates the role of 5-LOX metabolites in NSAIDs induced gastro inflammation and suggests that Montelukast and Curcumin counteracted the Indomethacin induced gastropathy by a combination of its effect on inhibition of neutrophil adherence and through decrease in related production of free radicals that disrupts integrity of stomach mucosa.ConclusionsExperimental data clearly demonstrated the role of LTs was indomethacin induced gastric ulcers. However, inhibition of ulcerogenic events by Montelukast and Curcumin is suggestive of an important balance between COX and 5-LOX products.

Haploidentical Hematopoietic Stem Cell Transplantation in Leukemia’s: Experience from a Cancer Center in India

There has been a surge in haploidentical hematopoietic stem cell transplantation (HSCT) in India recently. However, there is a paucity of data on haploidentical HSCT from India. The report is an analysis of data of haploidentical HSCT performed at our center. Analysis of patients with acute leukemia or chronic myeloid leukemia who underwent haploidentical HSCT during 2014–2019 was performed. The graft versus host disease (GVHD) prophylaxis was post-transplant Cyclophosphamide with Mycophenolate-mofetil and Cyclosporine. All patients were transfused peripheral blood stem cells from donors. Overall survival (OS) was calculated using the Kaplan–Meier method. Twenty-one patients underwent haploidentical HSCT. Fourteen-patients were males. The median age of patients was 15 years. Fludarabine with total body irradiation was the most common conditioning regimen (n = 15, 71.4%). The median duration for neutrophil and platelet engraftment was 14 days. Cumulative incidence of acute and chronic GVHD was 19%, and 38% respectively. The median follow-up was 26 months and the two-year OS was 38%. Twelve (57%) patients died during the study period, 8 patients (38%) died from transplant-related mortality (TRM), and 4 from disease relapse. Sepsis was the cause of death in six of the eight TRM. Nine out of 21 patients (42.8%) are leukemia-free on follow-up. Haploidentical HSCT is a promising modality of treatment in patients who have no suitable matched donors. Though the TRM remains high, good disease control was achieved in 42.8% of patients. Multi-drug resistant bacterial infection remains a challenge in performing haploidentical HSCT in developing countries.
