Accessing the veins for blood delivery, sampling or nutrition is a critical factor in the process of care and management of pediatric patients. In this regard, the peripherally inserted central catheter (PICC) is one of the main alternatives which could be applied effectively as traditional central venous devices in neonates and adults. Due to their essential role in providing safe central venous entry, PICCs could be applied extensively in patients who are critically ill. The main aims of the present study are to review approximately all relevant publications concerning PICC procedures, any possible complications, and the most appropriate decision for preventing these complications due to their high mortality rate. We carried out a comprehensive search on PubMed, HubMed, EMBASE, MEDLINE, Science Direct, Scopus, MEDLINE, and EMBASE databases for identifying the most relevant publications related to potential complications following the application and insertion of PICCs in hospitalized children and infants. Through appropriate care of catheters, the rate of possible infectious, mechanical and thrombotic complications would decrease considerably compared to those patients who received traditional central venous catheters. However, the process of vascular access in neonatal and children is very challenging. Any delay or denying treatment due to the lack of vascular access is intolerable. In this regard, anesthesiologists must achieve extra knowledge of various vascular devices.

Objective Sexual functioning is an important component of life quality and musculoskeletal disorders may effect sexual functioning, so, the present study was conducted to evaluate sexual functioning in patients suffering from back pain, rheumatoid arthritis, and systemic lupus erythematosus (SLE). Methods This study was conducted on 102 patients with rheumatoid arthritis, 103 patients with back pain, 103 patients with SLE, and 210 people in the control group by the consecutive sampling method. The marital satisfaction questionnaire (Enrich), Arizona Sexual Experience Scale (ASEX) questionnaire, and the General Health Questionnaire (GHQ‐28) were completed by all the subjects. Disease severity was determined in each group of patients by Disease Activity Score of 28 joints, the Roland Morris questionnaire, and the SLE Disease Activity Index questionnaire. Results The GHQ in rheumatoid arthritis and lupus patients was meaningfully higher than the control group (P < .05), while there was no meaningful difference between back pain patients and the control group (P = .414). The sexual functioning questionnaire score in all 3 groups showed no statistically meaningful difference with the control group (P < .05). Also, the marital satisfaction questionnaire score in all the groups showed no statistically meaningful difference compared to the control group (P = .791). Conclusion The study has shown that the level of sexual function in participants with back pain and the level of mental health and sexual functioning in patients with rheumatoid arthritis and SLE are significantly lower than healthy people and there is a need for intervention for improving mental health as well as sexual functioning in these patients.

Allogeneic Hematopoietic Stem Cell Transplantation (allo-HSCT) is the only known curative option for hematologic manifestations of Diamond-Blackfan anemia (DBA) as a rare inherited bone marrow failure syndrome. This treatment may be considered for DBA patients with corticosteroid-resistance, transfusion dependence, and/or progression to severe aplastic anemia or myelodysplastic syndrome (MDS)/ Acute myleloid leukemia (AML). In this prospective study, 10 pediatric DBA patients (age < 15 years) who underwent allo-HSCT from HLA-matched donors using non-TBI myeloablative conditioning regimen (intravenous busulfan and cyclophosphamide ± antithymocyte globulin) during September 2010 to February 2014 are reported. For Graft versus Host Disease (GvHD) prophylaxis cyclosporine A. and a short course of methotrexate were administered. Except one patient who received transplantation from his sibling cord blood, engraftment occurred in all the other patients (9 out of 10) with full donor chimerism (> 95%). The median neutrophil and platelet engraftment times were 11 (range, 10-13) days and 23 (range, 15-50) days, respectively. Acute GvHD developed in 7 patients. After a median follow-up of 53.3 months, 8 patients are still alive, of whom 7 patients are disease-free. The other two patients died due to grade III-IV acute GvHD. Our data suggests that allo-HSCT using busulan-based non-TBI myeloablative conditioning regimen could be a long-term effective treatment for DBA patients. Early transplantation especially before having multiple transfusions leading to iron overload, particularly from an HLAmatched sibling donor would be associated with favorable outcomes.

Background Coronavirus disease 2019 can lead to rare but severe and life-threatening diseases in susceptible high-risk populations, including patients with immunodeficiency. A rare event in this report is stroke following COVID-19 disease in a patient with an immunocompromised background due to leukemia and anti-cancer treatments. Case presentation A 6-year-old iranian girl with precursor B-cell leukemia receiving vincristine therapy presented with fever and absolute neutrophil count < 500. Her severe acute respiratory syndrome coronavirus 2 polymerase chain reaction test was positive. During hospitalization, she had abrupt onset tachypnea, reduced O2 saturation, and generalized tonic–clonic seizures treated with phenytoin and levetiracetam. Right parietal lobe ischemia was found on a brain computed tomography scan, and the cerebrospinal fluid polymerase chain reaction test was positive for severe acute respiratory syndrome coronavirus 2. Several days later, she developed lower extremity paralysis and speech impairment, so speech therapy and physiotherapy were initiated. The patient also received dexamethasone, mannitol, heparin, and remdesivir. She was discharged with enoxaparin and levetiracetam. Chemotherapy resumed 2 weeks following discharge. Her speech and walking improved after 10 months of follow-up, and bone marrow aspiration showed total remission. Conclusion Owing to the link between coronavirus disease 2019 and hematologic cancers with hypercoagulopathy and the tendency of patients with leukemia to have coronavirus disease 2019 complications, children with leukemia as well as suspected coronavirus disease 2019 must be hospitalized to prevent blood clot formation.

TB is an increasing health problem, and patients undergoing HSCT are more prone to develop tuberculosis. The aim of our study was to evaluate prevalence of latent tuberculosis in HSCT recipients. In this study, 84 patients (2 months to 18 years) who were candidates for HSCT at the referral hospital of Tehran Children's Medical Center were enrolled. The TST and the QFT‐GIT test were performed in all 84 patients, simultaneously. LTBI was considered when one of the tests was positive. Overall, the prevalence of LTBI in HSCT recipients in our study was 12% (10 cases). TST induration ≥5 mm was seen in only three patients (3.5%). Eight patients (9.5%) had a positive result for IGRA test, and 11 of them (13%) had indeterminate QFT‐GIT result. The agreement between the TST results (induration size ≥5 mm) and the QFT‐GIT results was poor (kappa = 0.14). In conclusion, there was a high rate of discordance between TST and IGRA results with many more positive QFT‐GIT tests. However, more studies are needed in this population to determine whether this discordance reflects true infection.
