Background Allergic rhinitis (AR) is a chronic and frequent condition characterized by an excessive response of the immune system to innocent substances encountered in the nasal mucosa. These reactions are mediated by many factors, including chemokines. Chemokine ligand 3 (CCL3, a macrophage inflammatory protein 1α) is a chemokine implicated in the activation of mast cells - white cells shown to be highly involved in orchestrating allergic reactions. The present study evaluated the role of CCL3 in AR. Material and methods Thirty-nine participants, including 24 patients with AR and 15 healthy controls, were evaluated for allergies to dust mites, cat and dog danders, cockroaches (Blatella germanica), molds, grasses, weeds, and tree pollen using skin prick tests. Participants were also evaluated for inflammatory conditions by measuring total blood count with differential; concentrations of rheumatoid factor, fibrinogen, and C-reactive protein; and erythrocyte sedimentation rate. CCL3 in blood samples was measured at the Immunology Laboratory, Cantacuzino National Institute for Military Medical Research and Development, Bucharest, Romania, using Human Multianalyte Profiling Base Kits (R&D Systems Inc., Minneapolis, MN). Results Mean serum CCL3 concentration was significantly higher in patients with AR than in controls (15.03 ± 7.11 pg/ml vs. 8.34 ± 4.46 pg/ml, p = 0.001 [t-test] and p = 0.026 [Mann-Whitney test]). CCL3 concentrations correlated with polysensitization, defined as two or more positive prick tests per patient (r = 0.325, p = 0.046) and seasonal AR (r = 0.482, p = 0.002). see more Conclusions Elevated levels of CCL3 were seen in our patients with AR. We have observed correlations with polysensitization and seasonal allergies. These results suggest that chemokines might play an important role in the pathogenesis of AR. In the future, chemokines might be used in endotype classification of patients with AR and as a possible target in the treatment of AR.Introduction Lumbar puncture (LP) is an effective method in the diagnosis and management of central nervous system infections. Refusal to LP is associated with severe consequences. This study aims to examine the impact of parental LP refusal on treatment, the length of hospital stay, and the frequency of patients leaving against medical advice (LAMA). Method A cross-sectional study was conducted at the pediatric department of Civil Hospital, Karachi, from June 2018 to November 2019. All hospitalized patients suspected to have a central nervous system disease, which requires LP, were enrolled. Patients were followed for the duration of antibiotic and antiviral therapy, length of hospital stay, and LAMA. Results A total of 220 patients participated in the study, with the median age of nine (2-47) months. There were 113 (51.1%) males. The median length of hospital stay was 10 (4-14) days. The comparison of parental LP refusal with the length of hospital stay showed a significant difference (p-value less then 0.001) in the number of days of treatment among patients who received vancomycin (p-value =0.008) and meropenem (p-value =0.012). A significant association of parental LP refusal was also observed with meningoencephalitis and meningitis as provisional diagnosis (p-value =0.006). In particular, LAMA and death were found significantly higher among parents who refused LP (p-value less then 0.001). Conclusion LP refusal has a significant effect on the treatment, hospital stay, and disposition outcomes. A large number of parents who declined the procedure left against medical advice or suffered grave medical consequences. Parental education addressing their concerns and beliefs, while explaining the indications, and need for performing LP can help effectively overcome this issue.Introduction There is often a need for a simple means of predicting hematocrit (Hct) following blood loss, administration of intravenous fluids, or fluid shifts. The aim of this study is to introduce a nomogram for the rapid prediction of blood volume and packed red cell volume appropriate for a given patient's body weight and Hct in both the pediatric and adult populations. Methods A nomogram for prediction of Hct was created using the following variables 1) blood volume determined from bodyweight, 2) estimated blood loss, and 3) initial Hct. Results Hct was calculated after blood loss, administration of intravenous fluids, or fluid shifts using the pediatric and adult nomograms. Alternatively, the nomograms can be used to back-calculate blood or fluid loss if Hct is known. The nomogram allows for adjustment for measured and insensible fluid losses and fluid administration. Conclusions The nomogram helps to predict the Hct and fluid requirements in neonates, children, and adults with blood loss, fluid administration, and rehydration following dehydration. It allows for the calculation of Hct after fluid shifts in a simple, fast, and portable manner. We believe it can be a useful adjunct to monitor the fluid balance in all patients, especially in resource-limited settings where laboratory equipment may not be available.Congenital anomalies involving the origin of coronary arteries are rare and the most common anomaly is left circumflex (LCX) arising from the right sinus of Valsalva (RSV). Other anomalies include a single coronary artery from the left sinus of Valsalva, both coronary arteries from RSV and left anterior descending coronary artery (LAD) from RSV. Anomalous origin of left main from RSV carries a high risk of sudden cardiac arrest. A retrospective analysis and literature review of three patients admitted to our medical center with the acute coronary syndrome, who underwent coronary angiography and were found to have left main coronary artery (LMCA) originating from the right coronary cusp (RCA). One patient had non-diseased coronaries with symptoms caused by the variant anatomy with possible compression of the LMCA, whereas the other two patients had 100% occluded RCA with variable stenosis in the left coronary system. Eventual surgical re-implantation with bypass grafting was required in all three patients. LMCA from the RSV is a rare, but often fatal anomaly.
