2023 catastrophic Turkey earthquake: clinical outcomes of pediatric patients rescued under the rubble.

OBJECTIVES: Children are the most vulnerable population affected by the earthquake. We aimed to examine the characteristics, morbidity, mortality, and the factors affecting these pediatric earthquake victims to guide the follow-up of pediatric patients who were rescued under the rubble in possible future disasters. METHODS: This is a retrospective observational study. The files of pediatric earthquake victims aged 0-18 years who were admitted to Adana City Training and Research Hospital between 6 February-30 April 2023 were analyzed. 318 patients were included in the study. RESULTS: Of all patients 48.7% (n = 155) were female and 51.3% (n = 163) were male. The mean age of the patients was 114.8 months. 65.4% (n = 208) of the patients were discharged from our hospital, eighteen patients (5.7%) died. Information on the hour when the patients were rescued under the rubble could be reached in 117 (36.8%) patients. The mean rescue time of these patients was 50.5 hours. 62 (53%) victims were rescued in the first 24 hours after the earthquake. There were 111 patients (34.9%) with fractures. There were 118 patients (37.1%) who underwent fasciotomy surgery. The total number of patients with amputation was 48 (15.1%). There were 36 patients (11.3%) with one limb amputated, 12 patients (%3.7) with more than one limb amputation. Internal organ injury was present in 30.5% (n = 97) of the patients. Of these patients, 85.6% (n = 83) had single organ trauma and 14.4% (n = 14) had multiple organ trauma. There were 58 patients (18.2%) with acute renal failure in follow-up. The mean rescue time for patients with amputation was 83.65 ± 62.9 hours, and for patients without amputation was 36.44 ± 50.6 hours. This difference was statistically significant (p = 0.001). No statistically significant difference was found when the ages of the patients were compared to fasciotomy, amputation, and fracture status. CONCLUSION: While evaluating earthquake-induced trauma, pediatric patients should be approached carefully.

Evaluation of Clinical Findings and Treatment Results of Coronavirus Disease 2019 (COVID-19) in Pediatric Cancer Patients: A Single Center Experience.

Objective: The objective of the study is to evaluate the clinical findings and treatment results of COVID-19 in pediatric cancer patients. Study design: The study was designed as a single-center retrospective observational study. Pediatric cancer patients with COVID-19 admitted to the University of Health Sciences Adana City Training and Research Hospital pediatric COVID wards from October 2020 to October 2021 were included. Clinical data and demographic characteristics were retrieved from patient files. Results: A total of 45 pediatric cancer patients diagnosed with COVID-19 were included in the study. The mean age of the patients was 8.68 ± 5.16 years (range 1.5-17.5), 62.2% were men, 37.8% were Turkish citizens, and 62.2% were Syrian refugees. A total of 41 patients (91.1%) had leukemia/lymphoma, while 4 (8.9%) had solid tumors. The most common symptoms were fever (66.7%), respiratory (35.6%), and gastrointestinal symptoms (17.8%). Disease severity was evaluated as mild in 46.7%, moderate in 44.4%, and severe in 8.9% of patients. Patients presented with lymphopenia (88.9%), thrombocytopenia (73.3%), anemia (71.1%), and neutropenia (62.2%). Mean hospital length of stay was 15.18 ± 10.34 (range 6-62) days overall and 9.5 ± 2.39 (range 2 to 28) days in the PICU. Intensive care unit admission rate was 8.9%, and mortality rate was 4.4%. Median viral shedding period was 21 days (range 7-52). Conclusions: Our study reveals that the mortality rate, length of hospital stay, and the need for intensive care of pediatric cancer patients with COVID-19 are higher than those of healthy children. Prospective studies with larger sample sizes are needed to further evaluate the clinical findings and treatment results of COVID-19 in pediatric cancer patients.

Pediatric anti-NMDA receptor encephalitis associated with COVID-19.

Anti-N-methyl-D-aspartate receptor encephalitis is a clinical condition characterized by acute behavioral and mood changes, abnormal movements, autonomic instability, seizures, and encephalopathy. We describe a 7-year-old boy diagnosed with autoimmune encephalitis due to NMDAR antibody in association with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (coronavirus disease 2019) (COVID-19), without pulmonary involvement or fever. The patient presented with acute ataxia, rapidly developed encephalopathy, and autoimmune encephalitis was suspected. Steroid treatment was withheld because of lymphopenia and intravenous immunoglobulin was started. The absence of clinical response prompted plasmapheresis and, when lymphocyte counts improved, pulse steroid treatment was applied. The latter was followed by significant improvement and the patient was discharged in a conscious and ambulatory state. Autoimmune encephalitis should be considered in the presence of neurological symptoms accompanying SARS-CoV-2 infection and steroid treatment should be preferred unless limited by contraindications.

Brucella Case That Led to Atlantoaxial Spinal Instability in Childhood.

BACKGROUND: Atlantoaxial subluxation caused by Brucella infection is rarely seen in children. CASE DESCRIPTION: C1-C2 dislocation, erosion in the odontoid bone, and compression to the brainstem were detected on cervical computed tomography and magnetic resonance imaging in a 6-year-old patient who suffered neck pain, deviation to the right in the neck, fever, and pain in his extremities. He was hospitalized in the Clinic of Pediatric Infectious Diseases. Positive Brucella agglutination tests were obtained, so C1-C2 stabilization and fusion were performed. Antibrucellosis antibiotic treatment was administered for 6 months. It was suggested that the dislocation was related to odontoid erosion and laxity of the atlantoaxial ligamentous structures during Brucella infection. CONCLUSIONS: Atlantoaxial dislocation and instability develops secondarily to paravertebral abscesses, only rarely. Like brucellosis of childhood, granulomatous infectious diseases rarely cause atlantoaxial subluxation or dislocation. Torticollis and neck pains should be taken seriously for the purpose of early diagnosis of patients at risk in endemic regions. Stabilization and fusion should be performed when instability is detected, and these patients should be assessed with both pediatric infectious diseases and neurosurgery clinics. Our case is the first one in the literature in which atlantoaxial instability developed due to Brucella infection and stabilization was performed.

Surgical approaches to upper thoracic Pott's disease with spinal instability during childhood: two cases.

PURPOSE: Tuberculosis is a common disease worldwide that is caused by Mycobacterium tuberculosis. Tuberculosis is primarily a pulmonary disease, but extrapulmonary manifestations are not uncommon, especially in children and adolescents. METHODS: We present two pediatric patients who underwent surgery in our clinic for Pott's disease in the upper thoracic region. The patients were investigated to describe their age, complaints, neurological examination results, disease location, surgical procedure, and complications. RESULTS: The patients were 2 and 14 years old and exhibited disease located in the upper thoracic region (T2-T3 and T1-T2). Both patients displayed severe neurological deficits (Frankel B and C). The kyphotic angles were 82.2° and 43.2°. The patients were stabilized by applying fusion using transpedicular screws via a posterior approach. They also underwent anti-tuberculosis treatment for approximately 1 year. One year later, neither patient exhibited any neurological deficit, and their kyphotic angles were measured as 11° and 1°, respectively. CONCLUSIONS: The recommended treatment approach for unstable cases of Pott's disease located in the upper thoracic region who exhibit neurological deficit and severe kyphotic angling or the development of kyphosis on the thoracic vertebrae is surgical. Decompression, stabilization, and fusion and kyphotic correction can be safely performed via a posterior approach. One of the present cases is the youngest patient described in the literature to undergo transpedicular surgery as a result of Pott's disease. Our other case is the first described in the literature who developed ptosis as a result of tuberculosis and underwent a procedure via posterior transpedicular screw.

Radiation pressure excitation of a low temperature atomic force/magnetic force microscope for imaging in 4-300 K temperature range.

We describe a novel radiation pressure based cantilever excitation method for imaging in dynamic mode atomic force microscopy (AFM) for the first time. Piezo-excitation is the most common method for cantilever excitation, however it may cause spurious resonance peaks. Therefore, the direct excitation of the cantilever plays a crucial role in AFM imaging. A fiber optic interferometer with a 1310 nm laser was used both for the excitation of the cantilever at the resonance and the deflection measurement of the cantilever in a commercial low temperature atomic force microscope/magnetic force microscope (AFM/MFM) from NanoMagnetics Instruments. The laser power was modulated at the cantilever's resonance frequency by a digital Phase Locked Loop (PLL). The laser beam is typically modulated by ∼500 µW, and ∼141.8 nmpp oscillation amplitude is obtained in moderate vacuum levels between 4 and 300 K. We have demonstrated the performance of the radiation pressure excitation in AFM/MFM by imaging atomic steps in graphite, magnetic domains in CoPt multilayers between 4 and 300 K and Abrikosov vortex lattice in BSCCO(2212) single crystal at 4 K for the first time.

Pediatric Lyme Neuroborreliosis: Different clinical presentations of the same agent; Single center experience.

OBJECTIVES: Lyme disease is a vector-associated infectious disease, caused by the agent, spirochete Borrelia burgdorferi. Neurologic findings are observed in approximately 12% of the cases and termed Lyme neuroborreliosis (LNB). Lyme neuroborreliosis may manifest with different clinical neurologic manifestations. METHODS: The study was conducted at tertiary training and research hospital. From January 2014 to September 2015, a total of 75 patients diagnosed with encephalitis, ataxia, Guillain Barre Syndrome (GBS), facial paralysis, acute disseminated encephalomyelitis (ADEM), pseudotumorcerebri were evaluated for inclusion to the study. Among these patients whom investigations of B. burgdorferi antibody IgM and/or IgG ELISA and Western Blot (WB) were detected to be positive, were assessed. Epidemiologic data, tick bite histories, duration of symptoms, clinical findings, radiologic findings, treatment durations and prognosis were investigated. RESULTS: Totally 7 patients had been treated with the diagnosis of Lyme neuroborreliosis. The mean age was 9.14±4.91 years; duration of symptoms before admission was 8.0±4.50 days; and the duration of antibiotic use was 2.85±0.89 weeks. All patients had received ceftriaxone and intravenous immunoglobulin (IVIG); 3 patients had received plasmapheresis (42.9%) and one patient had received pulse corticosteroid therapy. While the patient with the diagnosis of encephalomyeloneuritis and atypical GBS had partially improved, the other patients were completely cured. CONCLUSION: In this article, we report pediatric LNB patients, B. burgdorferi should also be considered in patients with atypical or severe neurologic involvement or a history of tick bite; it is known that the prognosis is good with appropriate and early treatment.

Placento-Cranial Adhesions in Amniotic Band Syndrome and the Role of Surgery in Their Management: An Unusual Case Presentation and Systematic Literature Review.

Amniotic band syndrome is a group of sporadic congenital anomalies that involve the limbs, craniofacial regions and trunk, ranging from simple digital band constriction to complex craniofacial and central nervous system abnormalities. Placento-cranial adhesions in amniotic band syndrome are extremely rare, and severe conditions are associated with high morbidity and mortality rates. In this study, we pooled placento-cranial adhesion case reports that were published in the medical literature and added an unpublished case from our institution. The purpose of this article was to review and discuss the clinical features and outcomes of placento-cranial adhesions in amniotic band syndrome.

An Adolescent Case of Osteopetrosis with Portal Hypertension as well as Mandibula Osteomyelitis.

Osteopetrosis is a clinical syndrome characterized by the failure of osteoclasts to resorb bone. Excessive bone density can interfere with vital tissues and structures, causing serious problems of the body. Hematopoietic insufficiency, disturbed tooth eruption, nerve entrapment syndromes, and growth impairment may develop in a patient with osteopetrosis. Herein, we present an adolescent girl diagnosed with non-infantile type of osteopetrosis with rare complications of the disease like mandibular osteomyelitis and portal hypertension (PHT) without liver cirrhosis. To our knowledge, this is the first pediatric case with osteopetrosis related PHT.

Cerebral salt wasting in pediatric critical care; not just a neurosurgical disorder anymore.

OBJECTIVE: Cerebral salt-wasting syndrome (CSWS) is a hypovolemic hyponatremia caused by natriuresis and diuresis, of which the exact pathogenesis is unknown. Although CSWS has been more commonly described to be associated with neurosurgical disorders, increasing numbers of patients are diagnosed and new etiological factors are being identified as the awareness of it increases. METHODS: The files of the patients who had been hospitalized and treated with the diagnosis of CSWS at the pediatric critical care unit during the last three years were retrospectively reviewed. RESULTS: Totally 9 patients had been treated with the diagnosis of CSWS. The causes of CSWS were identified as tuberculosis meningitis in two patients, status epilepticus in two patients, ketamine infusion in one patient, medulloblastoma in one patient, sepsis in one patient, brain oedema following child abuse in one patient, and cerebral infarct in one patient. All of the patients had received isotonic saline and hypertonic saline while 77.7% of them had received fludrocortisone. The mean time to correction of hyponatremia was 20.37±14.73 days. One patient had died. CONCLUSION: Cerebral salt-wasting syndrome is increasingly described in the etiology of hyponatremia that is commonly seen in children hospitalized especially at critical care units. Serum sodium, urinary sodium and polyuria should be primarily considered in the diagnosis, and supportive laboratory tests such as uric acid and brain natriuretic peptide (BNP) should not be stipulated. At hospitals providing inpatient care services, clinical and laboratory characteristics of CSWS should be known in detail especially at pediatric critical care units.

Awareness and attitude relating to the human papilloma virus and its vaccines among pediatrics, obstetrics and gynecology specialists in Turkey.

BACKGROUND: To determine the level of knowledge on human papillomavirus (HPV) infection and vaccination, and the attitude towards HPV vaccination in pediatricians, obstetricians and gynecologists (OBG). MATERIALS AND METHODS: Participants were administered a 40-question survey, investigating the demographic properties, the knowledge on the HPV infection-vaccination and attitudes towards vaccination. RESULTS: The study enrolled a total of 228 participants (131 pediatricians and 97 OBGs). At a rate of 99.6%, the participants agreed with the fact that the HPV infection was the most common sexually transmitted disease and 33.8% of the participants had the opinion that the HPV vaccination should be administered only in women. The lowest level of HPV vaccine recommendation was among the pediatrics specialists (59.4%, p=0.012). When asked whether they would have their daughters receive HPV vaccination, 79.5% of the participants answered favorably; this rate was 36.7% for the sons. At a rate of 59.5% of the participants thought that the HPV vaccine needed to be included in the national vaccine schedule. Most of the participants (91.6%) had the idea that reduction of the vaccine costs would increase the vaccination frequency. CONCLUSIONS: We observed that the consideration of the costs and the prejudices relating to the inefficacy of vaccination as well as the inadequate level of knowledge were involved in the physicians' resistance to HPV vaccination. We believe that the healthcare professionals should be informed adequately to overcome false beliefs, thereby ensuring success of the HPV vaccine upon inclusion in the national vaccine schedule in the future.

The assessment of PFA-100 test for the estimation of blood loss in renal transplantation operation.

BACKGROUND: Platelet dysfunction is well known factor that may play a role in bleeding diathesis in uremia. In recent years, Platelet Function Assay 100 (PFA-100) was introduced to measure platelet function. The purpose of this study was to determine whether an abnormal PFA-100 is an accurate predictor of bleeding in dialysis patients undergoing renal transplantation (RTx). MATERIAL/METHODS: We included 98 dialysis patients undergoing RTx operation. PFA-100 test measuring collagen/epinephrine (Col/EPI) and collagen/adenosine 5'-diphosphate (Col/ADP) closure was performed in each patients after induction of anesthesia. We compared intraoperative blood loss measured by gravimetric method during RTx operation method between patients with normal Col/EPI and Col/ADP closure times (group 1, n= 51) and with prolonged Col/EPI and Col/ADP closure times (group 2, n=47). RESULTS: Intraoperative blood loss calculated by gravimetric method was 273+/-50 ml in the group 1 and 303+/-109 ml in the group 2 (p>0.05). Blood loss in gross formula was 356+/-87 ml in the group 1 and 450+/-99 ml in group 2 (p>0.05). CONCLUSIONS: Assessment of platelet function with preoperative measurement of PFA-100 in RTx patients is not an effective method for estimating the risk of blood loss in the intraoperative and postoperative periods.

Impact of mold infections in explanted lungs on outcomes of lung transplantation.

INTRODUCTION: Little is known about the incidence or significance of mold infections in the explanted lungs of lung transplant recipients. METHOD: We reviewed the histopathology of the explanted lungs from 304 patients who underwent lung transplantation at our institution from 2005 to 2007 and received alemtuzumab induction therapy and posttransplant voriconazole prophylaxis. RESULTS: Invasive mold infections were present in the explanted lungs of 5% (14 of 304) of patients, including chronic necrotizing pneumonias (n=7), mycetomas (n=4), and invasive fungal pneumonias (n=3). Only 21% (3 of 14) received immunosuppressive therapy within 1 year before lung transplantation, suggesting that lung damage itself predisposed patients to mold infections. The risk of mold infection was higher in patients with cystic fibrosis (11%, 4 of 35) than other underlying lung diseases (4%, 10 of 269). Pulmonary mold infections were not diagnosed or suspected in 57% (8 of 14) of patients. Despite secondary voriconazole prophylaxis, fungal infections developed in 43% (6 of 14) of patients with mold infections of the explanted lungs compared with 14% (42 of 290) of patients without mold infections (P=0.01). Three patients developed invasive fungal infections while on voriconazole prophylaxis and three developed fungal infections more than 8 months after the discontinuation of voriconazole. The mortality attributable to invasive fungal infections among patients with mold infections of the explanted lungs was 29% (4 of 14). CONCLUSION: Invasive mold infections in the explanted lungs are often not recognized before lung transplantation and are associated with poor outcomes.

Systemic phaeohyphomycosis due to Exophiala (Wangiella) in an immunocompetent child.

We report a rare case of systemic lymphadenitis and hepatic involvement due to Exophiala (Wangiella) dermatitidis in a pediatric patient. An 8-year-old immunocompetent boy with chronic fever was examined through the use of sonography and CT scan which demonstrated cervical and mesenteric lymph node enlargement and numerous small hepatic lesions. The etiologic agent was isolated by means of lymph node aspiration. The fungus was identified by its morphological characteristics and through DNA sequencing of the internal transcribed spacer region of rDNA. Despite initial amphotericin B and voriconazole therapy, the child's jaundice subsided and he died 7 months later. In addition to pathogenic aspects of Exophiala dermatitidis, the diagnostic approaches and relevant therapeutic strategies are discussed.

[New approaches in antibiotic therapies in chronic pulmonary diseases]. / Cocuklarda kronik akciger hastaliklarinin antibiyotik tedavisinde yeni yaklasimlar.

Chronic lung diseases are one of the considerable problems in childhood both for physicians and patients. Due to early diagnosis of illness and complications; advances at vaccination methods and antibiotic therapies; life period of patients have been prolonged so not only at childhood but at adults, chronic lung diseases seem to be important healthy problem. One of the most important factors affecting to prognosis of the diseases are concominant infections. This review is an argument of antibiotic usage regimens at cystic fibrosis, bronchiectasis and allergic bronchopulmonary aspergillosis which are the most usual chronic lung diseases seen at childhood and adults.

Diagnostic dilemma in an adolescent boy: hemophagocytic syndrome in association with kala azar.

Leishmaniasis is caused by infection with the hemoparasite Leishmania. The disease is a major public health problem in at least 88 countries, including Turkey. Prolonged fever with anorexia and loss of appetite are the major presenting features of visceral leishmaniasis. It is rarely defined as an etiological cause of hemophagocytic syndrome. The clinical course triggered by leishmania infection and hemophagocytosis may coincide, and this may lead to considerable diagnostic difficulty, especially in young children. In this report, we describe an adolescent boy with visceral leishmaniasis as a rare cause of the hemophagocytic syndrome. This is the first reported association between hemophagocytosis and visceral leishmaniasis in an adolescent.

Aetiological agents, interleukin-6, interleukin-8 and CRP concentrations in children with community- and hospital-acquired pneumonia.

OBJECTIVE: To determine the pathogens causing pneumonia in community-acquired pneumonia (CAP) and hospital-acquired pneumonia (HAP) and to investigate serum levels of interleukin-6 (IL-6), interleukin-8 (IL-8) and CRP in pneumonia caused by different aetiological agents. STUDY DESIGN: Eighty-seven children (mostly < 5 years of age) were recruited in a prospective study, 55 of them with CAP without prior antibiotic treatment and 32 with HAP. Thirty healthy outpatient children served as controls. RESULTS: The causative micro-organisms were determined by serological and microbiological methods in 40 cases with CAP (72.7%) and 30 with HAP (93.7%). In CAP, M. pneumoniae was the most common causative agent (43.6%), followed by S. pneumoniae (20%) and C. pneumoniae (18.1%). Bacteria alone were the sole causative agents in only 21.8% of cases with HAP. Pseudomonas aeruginosa (34.3%) and K. pneumoniae (32.5%) were the most frequently isolated. Although IL-6 and IL-8 levels were raised, there was no statistical difference between the CAP and HAP groups, or between bacterial and mycoplasma infections; neither was there a difference in CRP levels between these two groups. CONCLUSION: The causes of pneumonia differ between CAP and HAP. Levels of IL-6, IL-8 and CRP are raised in pneumonia but are unhelpful in differentiating the various aetiologies.
