RESUMEN

The present investigation examined the impact of pomegranate (Punica granatum L.) juice on trace elements, minerals, and oxidative stress in relation to the potential harm inflicted by aluminum chloride (AlCl3) in rats. Rats were split into four groups at random for this purpose: control (C), pomegranate juice (PJ), aluminum chloride (A), and PJ + A. For 30 days, PJ was orally administered by gavage at a rate of 4 mL/kg every other day, whereas AlCl3 was administered intraperitoneally at 8.3 mg/kg. Spectrophotometric analysis was used to measure the levels of malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) enzyme activity in various tissues. In addition, high-resolution continuum source flame atomic absorption spectrometry (HR-CS FAAS) was used to determine the amounts of the elements Al, Cu, Fe, Mn, Zn, Ca, and Mg in the tissues. It was discovered that when PJ therapy was applied to all tissues, the antioxidant enzymes SOD and CAT activity increased, the GSH level rose, and the MDA level, a sign of lipid peroxidation, decreased. Al and Ca levels increased in the A group relative to the C group in all tissues, whereas they decreased in the A + PJ group relative to the A group. Group A exhibited a proportionate increase in Fe levels in the liver and renal tissues compared with group C. Furthermore, the A group's brain tissue had a higher Fe level than the C group's. The A + PJ group's brain tissue had a lower Fe level than the A group's. Our findings demonstrate that PJ therapy greatly decreased Al buildup and oxidative stress in tissues while controlling variations in trace element levels. In addition, it is concluded that PJ might have value as a strong chelating agent to prevent Al poisoning.

RESUMEN

Objective: This study aims to understand the presentations of autism spectrum disorder (ASD) patients in a tertiary hospital's emergency department (ED) in Turkey, and the difficulties of families face in the ED. Method: Clinical characteristics of ASD patients who presented to the ED between 1 January 2015 and 15 November 2020 were obtained by retrospective file review. The caregivers of the patients who had presented to the ED in 2020 were interviewed by a phone call. Results: There were 740 applications of 224 patients (192 boys, 32 girls). Almost half of the patients were between 0 and 5 years old. Respiratory problems were the most common cause of admissions in all age groups. The second common reasons for ED visits were gastrointestinal problems in 0-5 years old, traumatic injuries/poisoning in 6-12 years old, and epilepsy/syncope in 13-17 years old. Psychiatric problems were less common (2.7%) than other reasons for admission. The most challenging issue for children was "the crowded waiting area, and the long waiting period" and followed by "physical restraint imposed on the child," "noise," and "bright light." Conclusion: As the clinicians' awareness and use of more accurate diagnostic tools have increased, the ASD prevalence has gradually increased. To increase the quality of healthcare services for these patients, awareness studies and new interventions are needed.

RESUMEN

This study was conducted to determine the possible effects of long-term exogenous kisspeptin and its antagonist P234 on serum, liver and adipose tissue fatty acids (FA) profiles, as well as body weight, in female rats. Kisspeptin (50 pmol) and P234 (1 nmol) were administrated to the weaned Sprague-Dawley female rats by an intracerebroventricular injection from the 26th postnatal day to the 60th postnatal day. Percentages of the serum total saturated FA (∑SFA) and total monounsaturated FA (∑MUFA) were lower in the kisspeptin group. In the adipose tissue, ∑SFA was lower and total unsaturated FA higher in the P234 group. Moreover, long-term central kisspeptin injection caused a decrease in the body weight. When compared to the kisspeptin group, the final body weights were higher in the P234 and kisspeptin + P234 groups. According to our results, we suggest that kisspeptin has a regulatory role in FA metabolism and regulation of body weight.

RESUMEN

Subdural empyema refers to the collection of purulent material in the subdural space and the most source of it is bacterial meningitis in infants while sinusitis and otitis media in older children. It has been very recently reported that coronaviruses (CoV) exhibit neurotropic properties and may also cause neurological diseases. CoV-related complications as hypercoagulability with thrombosis and associated inflammation, catastrophic cerebral venous sinus thrombose sand bacterial-fungal superinfections have been well documented in adult patients. Hereby, we describe 15-year-old and 12-year-old female children with subdural empyema after SARS-CoV2. The patients presented limitation of eye in the outward gaze, impaired speech, drowsiness, fever, vomiting and they also were tested positive for COVID-19. MRI indicated subdural empyema and surgical interventions were needed to relieve intracranial pressure and drain pus after receiving broad spectrum antibiotics treatments. The microbiological analysis of abscess material revealed Streptococcus constellatus which is extremely rare in an immunocompetent child and the patients received appropriate IV antibiotic therapy. Eventually, patients became neurologically intact. Pediatric patients with CoV infections should be closely monitored for neurological symptoms. Further research and more data on the correlation between CoV infections would provide better recognition and treatment options in an efficient manner in children.

RESUMEN

Alterations of essential elements in the brain are associated with the pathophysiology of many neuropsychiatric disorders. It is known that chronic/overwhelming stress may cause some anxiety and/or depression. We aimed to investigate the effects of two different chronic immobilization stress protocols on anxiety-related behaviors and brain minerals. Adult male Wistar rats were divided into 3 groups as follows (n = 10/group): control, immobilization stress-1 (45 minutes daily for 7-day) and immobilization stress-2 (45 minutes twice a day for 7-day). Stress-related behaviors were evaluated by open field test and forced swimming test. In the immobilization stress-1 and immobilization stress-2 groups, percentage of time spent in the central area (6.38 ± 0.41% and 6.28 ± 1.03% respectively, p < 0.05) and rearing frequency (2.75 ± 0.41 and 3.85 ± 0.46, p < 0.01 and p < 0.05, respectively) were lower, latency to center area (49.11 ± 5.87 s and 44.92 ± 8.04 s, p < 0.01 and p < 0.01, respectively), were higher than the control group (8.65 ± 0.49%, 5.37 ± 0.44 and 15.3 ± 3.32 s, respectively). In the immobilization stress-1 group, zinc (12.65 ± 0.1 ppm, p < 0.001), magnesium (170.4 ± 1.7 ppm, p < 0.005) and phosphate (2.76 ± 0.1 ppm, p < 0.05) levels were lower than the control group (13.87 ± 0.16 ppm, 179.31 ± 1.87 ppm and 3.11 ± 0.06 ppm, respectively). In the immobilization stress-2 group, magnesium (171.56 ± 1.87 ppm, p < 0.05), phosphate (2.44 ± 0.07 ppm, p < 0.001) levels were lower, and manganese (373.68 ± 5.76 ppb, p < 0.001) and copper (2.79 ± 0.15 ppm, p < 0.05) levels were higher than the control group (179.31 ± 1.87 ppm, 3.11 ± 0.06 ppm, 327.25 ± 8.35 ppb and 2.45 ± 0.05 ppm, respectively). Our results indicated that 7-day chronic immobilization stress increased anxiety-related behaviors in both stress groups. Zinc, magnesium, phosphate, copper and manganese levels were affected in the brain.

RESUMEN

The purpose of this study was to investigate the potential side-effects of lead acetate (LA), which is toxic to the nerves, blood and muscles, in the rat brain. The neuroprotective effects of pomegranate juice (PJ) against LA exposure were also observed. The experiment involved 28 male Wistar albino rats aged 12 weeks. These were divided into four groups: Control, PJ, LA and LA+PJ. Stereological techniques were employed to determine hippocampal volume in each rat brain. Biochemical investigations and histopathological examinations were also performed. Analysis demonstrated a significant decrease in hippocampal volume in the LA group compared to the control group (p < .05). The stereology results also indicated that PJ has protective effects when compared with the LA and LA+PJ groups. A significant increase was also determined in malondialdehyde (MDA) levels and glutathione S-transferase (GST) activity in the LA group compared to the control group, in contrast to glutathione (GSH) levels and carboxylesterase (CaE) and acetylcholinesterase (AchE) activities. MDA and GST activity decreased significantly in the LA+PJ group compared to the LA group in contrast to GSH levels and CaE and AchE activities. Histopathological examination revealed a number of degenerative changes in the LA group. Exposure to LA adversely affects the hippocampus on the male rat brain. It might also be suggested that PJ may ameliorate these deleterious effects.

RESUMEN

In this study, the effects of 3-benzoyl-7-hydroxy coumarin molecule on mineral and antioxidant enzymes were investigated in rat liver exposed to oxidative stress with aluminium chloride (AlCl3). Adult male Wistar albino rats were divided into four groups as Control, Coumarin, AlCl3, and Coumarin + AlCl3. Coumarin at the dose of 10 mg / kg and AlCl3 at the dose of 8.3 mg / kg were administered for 30 days every other day. In AlCl3 group, malondialdehyde (MDA), iron (Fe), aluminium (Al) and copper (Cu) levels increased compared to the control group, while glutathione (GSH) level, glutathione S-transferase (GST), and carboxylesterase (Ces) enzyme activity levels decreased. In Coumarin + AlCl3 group, MDA, Fe, Al and Cu levels decreased with the effect of coumarin compared to AlCl3 group, while GSH level, and GST enzyme activity levels increased. According to our results, AlCl3 generates oxidative stress in rat livers, and we believe that 3-benzoyl-7-hydroxy coumarin has an ameliorative effect on antioxidant enzyme system, Al, Fe and Cu levels.

RESUMEN

OBJECTIVES: The purposes of this study were to determine the benefit of the bronchiolitis ultrasound score (BUS) in predicting hospital admission in children with acute bronchiolitis and to characterize lung sonography findings. METHODS: This prospective observational study was performed in an academic pediatric emergency department. Children younger than 24 months presenting to the emergency department, diagnosed with acute bronchiolitis by 2 independent pediatricians were included in the study. Lung ultrasound was performed by a single sonographer, who was blinded to as much clinical information as possible. In addition, the treating physicians were blinded to the lung ultrasound findings. Logistic regression analysis models were used to identify admission predictors. Receiver operating characteristic analysis was used to evaluate the predictive value for effects of the BUS and the modified Bronchiolitis Severity Score on admission. RESULTS: The median age of the 76 patients diagnosed with acute bronchiolitis was 6 months (interquartile range, 3.6-10 months). Forty-two (55.3%) of the 76 patients enrolled were admitted. Lung ultrasound was compatible with acute bronchiolitis in 74 patients (97%). A significant correlation was determined between modified Bronchiolitis Severity Score and BUS in children with acute bronchiolitis (r = 0.698, P < 0.001). The most effective parameter in determining admission on logistic regression analysis, independently of other variables, was BUS (P = 0.044; adjusted odds ratio, 1.859; 95% confidence interval, 1.016-3.404). Bronchiolitis ultrasound score values of 3 or greater exhibited 73.81% sensitivity and 73.53% specificity, whereas BUS values of 4 or greater exhibited 50% sensitivity and 91.18% specificity. CONCLUSIONS: Point-of-care lung ultrasound can accurately detect pulmonary anomalies in children with acute bronchiolitis, has a close correlation with clinical findings, and is a useful tool in predicting hospital admission.

RESUMEN

The aim of this study was to evaluate the thyroid function alterations in a group of epileptic children taking antiepileptic drugs. The study included a total of 183 pediatric epilepsy patients, aged 15 months-16 years, comprising 114 patients treated with valproic acid, 69 patients treated with phenobarbital, and 151 age-matched healthy volunteers as the control group. Serum levels of thyroid hormones were measured before the beginning of the antiepileptic therapy and after 12 months of treatment. Thyroid-stimulating hormone levels were significantly higher in the 12th month of phenobarbital and valproic acid treatment. The level of free triiodothyronine before treatment was higher in epileptic patients than in the control group. Subclinical hypothyroidism at month 12 was determined in 15.2% of the valproic acid group and in 2.9% of the phenobarbital group. When compared with the pre-treatment values, there was a statistically significant difference in the incidence of subclinical hypothyroid in the valproic acid group and no significant difference in the phenobarbital group. Symptomatic hypothyroidism was not detected. It was concluded that the thyroid functions of patients using valproic acid and phenobarbital for a long time should be regularly monitored.

RESUMEN

Cyclotrichium niveum is an endemic plant for Turkey and it appears to have in vitro antioxidant and acetylcholinesterase inhibition properties. To the best of our knowledge, there has been no study on the in vivo effects of this plant. Therefore, the purpose of this study was to evaluate the effects of C. niveum on lead (Pb)-acetate-induced potential alterations in brain acetylcholinesterase activity, as well as oxidative stress in male rats. The rats were randomly assigned to control, Pb-acetate, C. niveum and Pb-acetate+ C. niveum groups. Pb-acetate was provided in drinking water (500 ppm), and C. niveum was administered via orogastric gavage (4 ml/kg) for 30 days. The acetylcholinesterase activity in the brain significantly decreased only in the Pb-acetate group. The malondialdehyde level significantly increased, and the reduced glutathione activity decreased in the Pb-acetate group. The reduced glutathione and glutathione-S-transferase activities of the C. niveum group were higher than the control group. No Pb was detected on a ppb level in the brain tissue of the control and C. niveum groups, while it was detected in the brains of the rats in the Pb-acetate and Pb-acetate+ C. niveum groups (185+8.98 ppb and 206+56.65 ppb, respectively). The data collected in this study suggested that C. niveum may reduce inhibition of brain AChE activity and oxidative stress against Pb-acetate-induced alterations in the brain of male rats.

RESUMEN

Background Cerebral edema is a fatal complication that can occur in children with diabetic ketoacidosis (DKA). Its clinical signs are generally not explicit, and subclinical cerebral edema can occur. This study is one of the few longitudinal studies conducted to identify cerebral edema in patients with DKA by measuring the optic nerve sheath diameter (ONSD). The aim of this study was to investigate cerebral edema in children with DKA with serial measurement of ONSD, which is an early and reliable indicator of cerebral edema, and to monitor changes in ONSD during therapy. Methods The study was conducted by measuring ONSD ultrasonographically at baseline and during the course of therapy in patients with DKA. All participants were diagnosed and received therapy at our unit between May 2016 and June 2017. The study was registered with the Clinical Trials database, with a study number of NCT02937441. Measurements were obtained while the patients were in the supine position with their eyes closed, and axial transbulbar images of both eyes were obtained with a 6-15-MHz linear probe. Results The ONSD values of children with DKA changed during the treatment, reaching the highest values at 12-16 h of therapy, and the greatest ONSD was observed in children who had moderate and severe DKA. Conclusions During treatment of children with DKA, it is possible to predict cerebral edema by measuring ONSD, and this may contribute to clinical management, especially fluid treatment.

RESUMEN

OBJECTIVE: The purpose of this study was to evaluate the feasibility and diagnostic benefit of point-of-care ultrasound (PoCLUS) in children with non-cardiac respiratory distress or tachypnea. METHODS: In this prospective observational study, children aged between 1 month and 18 years with respiratory distress, tachypnea, or both, at triage were included. Concordance and accuracy of the emergency department (ED) and ultrasound diagnoses, length of stay, and time elapsing until ED and ultrasound diagnoses were calculated. RESULTS: One hundred forty-five patients were evaluated. The mean age of the children in the study was 67 ±â€¯58 months. Seventy-nine patients (56%) were boys. Mean length of stay in the ED was 124.6 ±â€¯76.5 min. Mean time to ultrasound diagnosis was 29.32 ±â€¯15.71 min, compared to 46.75 ±â€¯32.65 min for ED diagnosis, which was significantly longer (p < 0.001). Concordance between ultrasound and ED diagnoses was almost perfect for pneumonia, acute bronchiolitis, asthma and croup (0.8 < Ƙ < 1), and good for other non-pulmonary causes (0.6 < Ƙ < 0.8). Overall concordance for all diagnoses was also good (Ƙ = 0.76). Ultrasound diagnosis was more sensitive than ED diagnosis for pneumonia, acute bronchiolitis, and other non-pulmonary causes (81.4%-74.42%; 97.3%-86.49%; and 100%-95.83%, respectively). In addition, ultrasound diagnosis was more specific than ED diagnosis for pneumonia, acute bronchiolitis and other non-pulmonary causes (100%-97.35%; 99.07%-98.15%; and 93.39%-88.43%, respectively). However, ultrasound and ED diagnoses exhibited similar sensitivity and specificity values for asthma (97.22%-97.22%; and 99.08%-100%). CONCLUSION: PoCLUS may constitute a beneficial and rational approach in the evaluation of children with increased work of breathing in the ED, and can also expedite the diagnostic process.

RESUMEN

OBJECTIVE: Elemental mercury is a toxic liquid element that is used widely in the home, medicine, agriculture, and industry. It is readily vaporized and inhaled at room temperature. Thereby, inhalation can cause acute or chronic poisoning. Mercury can be found in environmental naturally find but some dangers sources give rise to contaminations. It can be very dangerous to all living organisms, especially children. METHODS: This study presents the features of mercury poisoning in a group of pediatric cases. Data were obtained for 29 pediatric cases exposed to elemental mercury in a high school chemistry laboratory in Turkey. Patients with a blood mercury level exceeding 10 µg/L or a urine mercury level exceeding 15 µg/L were considered to have mercury poisoning. The patients were treated with 2,3-dimercaptopropane sulfonic acid or D-penicillamine. RESULTS: Twenty-nine children with mercury poisoning were admitted to the hospital. The median duration of exposure was 58 (range, 15-120) minutes. Ten (29%) children were asymptomatic. Physical and neurological examinations were normal in 19 (65.5%) children. The most common presenting complaint was headache. The most common neurological abnormality, partly dilated/dilated pupils, was present in 9 (31%) children. Mercury levels were measured in blood samples every 5 days, and the median blood mercury level was 51.98 (range, 24.9-86.4) µg/L. There was a positive correlation between the duration of exposure and maximum blood/urine mercury levels (P = 0.001). CONCLUSIONS: Elemental mercury exposure is potentially toxic; its symptomatology varies, especially in children. Secure storage of mercury and other toxic substances and provision of information about this subject to individuals who might be exposed to mercury and their families might help to prevent mercury poisoning.

RESUMEN

In this study, the effect of geraniol (50 mg/kg for 30 d), a natural antioxidant and repellent/antifeedant monoterpene, in a rat model of lead acetate-induced (500 ppm for 30 d) liver damage was evaluated. Hepatic malondialdehyde increased in the lead acetate group. Reduced glutathione unchanged, but glutathione S-transferase, glutathione reductase, as well as carboxylesterase activities decreased in geraniol, lead acetate and geraniol + lead acetate groups. 8-OhDG immunoreactivity, mononuclear cell infiltrations and hepatic lead concentration were lower in the geraniol + lead acetate group than the lead acetate group. Serum aspartate aminotransferase and alanine aminotransferase activities increased in the Pb acetate group. In conclusion, lead acetate causes oxidative and toxic damage in the liver and this effect can reduce with geraniol treatment. However, we first observed that lead acetate, as well as geraniol, can affect liver carboxylesterase activity.

RESUMEN

Testis tissue is prone to oxidation because its plasma membrane contains many polyunsaturated fatty acids. Naringenin is a plant-derived natural flavonoid. We investigated the possible ameliorative role of naringenin on the hydrogen peroxide (H2 O2 )-induced testicular damage in Wistar rats. Animals received 12 mg/kg H2 O2 by intraperitoneal injection, and 50 mg/kg naringenin via orogastric gavage for 4 weeks. In the H2 O2 group, the testis malondialdehyde level increased, while the amount of reduced glutathione, glutathione transferase activities, and the testis weight decreased. There were severe testicular damages in the H2 O2 group otherwise their grade were less in the naringenin + H2 O2 group. However, the serum testosterone concentrations decreased in both the H2 O2 and the naringenin + H2 O2 groups. The testicular zinc and calcium levels reduced in the H2 O2 -treated rats. In conclusion, the administration of H2 O2 caused oxidative stress in the testes and naringenin supplementation decreased the H2 O2 -induced effects, except for changes in testosterone levels.

RESUMEN

BACKGROUND: We have investigated the effects of α-lipoic acid (LA), a powerful antioxidant, on the fatty acid (FA) profiles, aluminum accumulation, antioxidant activity and some minerals such as zinc, copper and iron against aluminum chloride (AlCl3)-induced oxidative stress in rat liver. METHODS: Twenty-eight male Wistar rats were divided into four groups as control, LA, AlCl3 and LA+AlCl3. For 30 days, LA was intraperitoneally administrated (50 mg/kg) and AlCl3 was given via orogastric gavage (1600 ppm) every other day. RESULTS: AlCl3-treated animals exhibited higher hepatic malondialdehyde concentration and lower glutathione peroxidase and catalase activity, whereas these alterations were restored by the LA supplementation. Total saturated FA of the AlCl3-treated group was higher than the LA supplementation groups. Moreover, total unsaturated FA level of the LA+AlCl3 group was higher than the AlCl3-treated group. Hepatic zinc level of the AlCl3-treated group was lower than the control group, whereas it was higher in the LA and the LA+AlCl3 groups. Hepatic copper levels did not significantly change in the experimental groups. Iron level was lower in the LA and LA+AlCl3 groups compared with the AlCl3-treated group. Moreover, the liver Al concentration was found to be lower in the LA and LA+AlCl3 groups compared to the AlCl3 group. CONCLUSIONS: These results indicate that AlCl3 treatment can induce oxidative stress in the liver. LA supplementation has a beneficial effect on the AlCl3-induced alterations such as high lipid peroxidation, Al accumulation, FA profile ratios and mineral concentrations.

RESUMEN

BACKGROUND: Hydrogen peroxide (H2O2) is an oxidant agent and this molecule naturally occurs in the body as a product of aerobic metabolism. Geraniol is a plant-derived natural antioxidant. The aim of this study was to determine the role of geraniol on hepatic fatty acids alterations following H2O2-induced oxidative stress in male rats. METHODS: After randomization, male Wistar rats were divided into four groups (n = 7 each group). Geraniol (50 mg/kg, dissolved in corn oil) and H2O2 (16 mg/kg, dissolved in distilled water) were administered by an intraperitoneal injection. Administrations were performed during 30 days with 1-day interval. RESULTS: Administration of H2O2 resulted with a significant increase in malondialdehyde (MDA) and a significant decrease in glutathione (GSH) peroxidase glutathione level; geraniol restored its effects on liver. However, hepatic catalase (CAT) activities were significantly higher in H2O2, geraniol, and geraniol+H2O2 groups than control group. The ratio of hepatic total saturated fatty acids increased in H2O2-treated animals compared with control. In addition, hepatic total unsaturated fatty acids reduced in H2O2 group compared with control. The percentages of both hepatic total saturated and unsaturated fatty acids were not different between geraniol+H2O2 and control groups. CONCLUSIONS: H2O2-induced oxidative stress may affect fatty acid composition in liver and body. Geraniol can partly restore oxidative hepatic damage because it cannot completely reverse the H2O2-induced increase in hepatic CAT activities. Moreover, this natural compound can regulate hepatic total saturated and unsaturated fatty acids percentages against H2O2-induced alterations.

RESUMEN

OBJECTIVES: To present lung ultrasound findings in children assessed with suspected pneumonia in the emergency department and to show the benefit of lung ultrasound in diagnosing pneumonia in comparison with chest X-rays. METHODS: This observational prospective study was performed in the pediatric emergency department of a single center. Point of care lung ultrasound was performed on each child by an independent sonographer blinded to the patient's clinical and chest X-ray findings. Community acquired pneumonia was established as a final diagnosis by two clinicians based on the recommendations in the British Thoracic Society guideline. RESULTS: One hundred sixty children with a mean age of 3.3±4years and a median age of 1.4years (min-max 0.08-17.5years) were investigated. Final diagnosis in 149 children was community-acquired pneumonia. Lung ultrasound findings were compatible with pneumonia in 142 (95.3%) of these 149 children, while chest X-ray findings were compatible with pneumonia in 132 (88.5%). Pneumonia was confirmed with lung ultrasound in 15 of the 17 patients (11.4%) not evaluated as compatible with pneumonia at chest X-ray. While pneumonia could not be confirmed with lung ultrasound in seven (4.6%) patients, findings compatible with pneumonia were not determined at chest X-ray in two of these patients. When lung ultrasound and chest X-ray were compared as diagnostic tools, a significant difference was observed between them (p=0.041). CONCLUSIONS: This study shows that lung ultrasound is at least as useful as chest X-ray in diagnosing children with community-acquired pneumonia.

RESUMEN

BACKGROUND: Lumbar puncture (LP) is one of the essential diagnostic tools in pediatric emergency services. Recently, ultrasound-assisted LP was reported to be beneficial in the emergency service by facilitating the procedure and improving the successful procedure rates. In addition, this method may be effective in reducing patient and parent anxiety due to the LP procedure. OBJECTIVES: The aim of this study was to investigate the effect of ultrasound-assisted LP on the outcomes of puncture procedures and traumatic LP. METHODS: The study included patients younger than 18 years, who were admitted to the pediatric emergency service and underwent LP because of suspected central nervous system infection. The patients requiring LP were randomly divided into 2 groups designated as odd and even. One group received LP using the conventional method, whereas the other group had LP after spinal space measurement by ultrasound. The patients who did and who did not undergo ultrasound-assisted LP were compared for demographics, number of puncture attempts, and traumatic LP. Statistical analysis was performed using the Mann-Whitney U test and the Student t test. The χ test was used when nominal data were compared between the 2 groups. RESULTS: Ultrasound-assisted LP was performed in 56 patients, and LP by using conventional method was performed in 55 patients. There was traumatic LP in 5 (8.9%) of the patients who underwent ultrasound-assisted LP and 9 (16.3%) of the patients who underwent LP using the conventional method (P > 0.05). The number of puncture attempts was 2 or more in 2 (3.5%) of the patients who underwent ultrasound-assisted LP and 5 (9%) of the patients who had LP using the conventional method (P > 0.05). CONCLUSIONS: Ultrasound-assisted LP reduced traumatic LP and the number of puncture attempts in pediatric patients; however, the results were not statistically significant.
