RESUMO

PURPOSE: In this prospective study, we aimed to investigate the difference in voice acoustic parameters between girls with idiopathic central precocious puberty (ICPP) and those who developed normally during prepuberty. MATERIALS AND METHODS: Our study recruited 54 girls diagnosed with ICPP and randomly sampled 51 healthy prepubertal girls as the control. Tanner stages, circulating hormone levels and bone ages of the girls with ICPP and the age and body mass index (BMI) of all participants were recorded. Acoustic analyses were performed using PRAAT computer-based voice analysis software and the mean pitch (F0), jitter, shimmer, noise-to harmonic-ratio (NHR) and harmonic-to-noise ratio (HNR) values were compared in the patient and control groups. RESULTS: The two groups did not significantly differ in age or BMI. In the evaluation of the F0 and jitter values, we were found to be lower in the control group than in the patient group. However, we did not find a statistical significance. The mean shimmer values of the patient group were significantly higher than those of the control group. In addition, a statistically significant difference was noted for the mean HNR and NHR values (P < 0.001). A moderate negative correlation was found between shimmer and hormone levels in the patient group. CONCLUSIONS: Voice acoustic parameters one of the defining features of girls with ICPP. Voice changes in acoustic parameters could reflect hormonal changes during puberty. Clinicians should suspect ICPP when there is a change in the voice.

RESUMO

INTRODUCTION: Findings of inadequate tissue perfusion might be used to predict the risk of mortality. In this study, we evaluated the effects of lactate and lactate clearance on mortality of patients who had undergone extracorporeal membrane oxygenation (ECMO). METHODS: Patients younger than 18 years old and who needed venoarterial ECMO support after surgery for congenital heart defects, from July 2010 to January 2019, were retrospectively analyzed. Patients successfully weaned from ECMO constituted Group 1, and patients who could not be weaned from ECMO were in Group 2. Postoperative clinics and follow-ups of the groups including mortality and discharge rates were evaluated. RESULTS: There were 1,844 congenital heart surgeries during the study period, and 55 patients that required ECMO support were included in the study. There was no statistically significant difference between the groups regarding demographics and operative variables. The sixth-, 12th-, and 24th-hour lactate levels in Group 1 were statistically significantly lower than those in Group 2 (P=0.046, P=0.024, and P<0.001, respectively). There were statistically significant differences regarding lactate clearance between the groups at the 24th hour (P=0.009). The cutoff point for lactate level was found as ≥ 2.9, with 74.07% sensitivity and 78.57% specificity (P<0.001). The cutoff point for lactate clearance was determined as 69.44%, with 59.26% sensitivity and 78.57% specificity (P=0.003). CONCLUSION: Prognostic predictive factors are important to initiate advanced treatment modalities in patients with ECMO support. In this condition, lactate and lactate clearance might be used as a predictive marker.

RESUMO

BACKGROUND: The splenic artery, an essential component of abdominal vascular anatomy, exhibits significant variations with clinical implications in surgical and radiological procedures. The lack of a standardized classification system for these variations hinders comparative studies and surgical planning. This study introduces the IPALGEA classification system, based on computed tomography angiography (CTA) findings, to address this gap. METHODS: A retrospective analysis was conducted on 302 patients who underwent CTA at a tertiary university hospital between August 2021 and January 2022. The study focused on the evaluation of splenic artery variations, including the origin, course, terminal branching patterns, and the relationship between the inferior polar artery and the left gastroepiploic artery. The IPALGEA classification was developed to standardize the reporting of these variations. RESULTS: The study highlighted a significant prevalence of splenic artery variations, with the most common pattern being a superior course relative to the pancreas. The IPALGEA classification effectively categorized these variations, emphasizing the relationship between the inferior polar artery and the left gastroepiploic artery. The findings revealed that the bifurcation distance of the celiac trunk varied significantly between genders and that the presence of an inferior polar artery correlated with a shorter hilus distance. CONCLUSION: The IPALGEA classification offers a comprehensive and standardized approach to categorize splenic artery variations. This system enhances our understanding of abdominal vascular anatomy and has significant implications for surgical and radiological procedures, potentially reducing surgical complications and improving patient outcomes.

RESUMO

OBJECTIVE: This study aimed to evaluate the relationship between sleep disturbances in children with epilepsy (CWE) and maternal sleep quality and depression severity. METHODS: A Cross-sectional study was conducted in pediatric sleep disturbances using questionnaires on mother-reported sleep of CWE [Children's Sleep Habits Questionnaire (CSHQ)], maternal sleep quality [Pittsburgh Sleep Quality Index (PSQI)], and maternal depression status [Self-Rating Depression Scale (SDS)]. 114 dyads consisting of CWE and their mothers were included in this study. RESULTS: Over three-quarters (78.9 %) of mothers reported poor sleep quality (total PSQI score ≥ 5), and nearly a third (29.8 %) met clinical criteria for moderate or severe depression levels. The mothers' total PSQI scores were between 5.93 ±â€¯2.44 (range: 2-16 points). The most affected PSQI subcomponents were sleep latency (AUC = 0.826p < 0.001) and daytime dysfunction (AUC = 0.800p < 0.001). The majority of children (88.6 %) were stated by their mothers to have sleep-related problems. The total CSHQ scores of the children were between 49.06 ±â€¯9.20 (range: 33-86 points). The most affected CSHQ subcomponents were detected sleep anxiety (AUC = 0.856, p < 0.001), bedtime resistance (AUC = 0.818, p < 0.001) and daytime sleepiness (AUC = 0.807, p < 0.001). There was a statistically significant positive correlation between maternal sleep quality and depression severity (rho = 0.842; p < 0.001). A statistically significant positive moderate correlation was detected between sleep problems in CWE and maternal sleep quality and depression severity (rho = 0.406; p < 0.001, rho = 0.399; p < 0.001, respectively). As a result of multiple stepwise logistic regression analysis, the presence of seizures during sleep and generalized epileptiform discharges on electroencephalography were associated risk factors with poor maternal sleep quality (OR:6.6, p = 0.014; OR:11.5, p = 0.018, respectively). A borderline insignificant relationship was observed between a less than 50 % decrease in seizure frequency and the poor maternal sleep quality (OR:20.59p = 0.059). Seizures during sleep was associated risk factor with children's sleep disturbances (OR:7.2, p = 0.02). CONCLUSIONS: Sleep problems in CWE may lead to negative consequences such as sleep quality and/or depression in mothers. Interventions planned to correct sleep disturbances in mothers suggest that children's sleep problems should be optimally managed.

RESUMO

BACKGROUND: Breast cancer (BRCA) is the most common and leading cause of cancer-related death in women. MicroRNAs (miRNAs) are short non-coding RNA fragments that play a role in regulating gene expression including the cancer-related pathways. Although dysregulation of miR-223 has been demonstrated in recent studies to have prognostic value in various cancers, its diagnostic and prognostic role in BRCA remains unknown. METHODS: The expression and the prognostic value of miR-223 were evaluated using the TCGA data and verified by qRT-PCR. Subsequently, potential oncogenic targets of miR-223 were identified by using three different miRNA target prediction tools and the GEPIA database. In addition to these databases, protein-protein interaction network, molecular functions, prognostic value, and the expression level of miR-223 targets were included by using several other bioinformatics tools and databases; such as, UALCAN, GeneMANIA and Metascape. RESULTS: The bioinformatic results demonstrated that miR-223 downregulated in BRCA and associated with poor prognosis of patients. In vitro experiments validated that miR-223 significantly downregulated in BRCA cells, MCF-7, SK-BR3, MDA-MB-231 and HCC1500, compared to normal breast cell line hTERT-HME1. Furthermore, ANLN, DYNLT1, LRRC59, SLC12A8 and TPM3 genes were identified as the potential oncogenic target genes of miR-223 based on their expression and prognosis in BRCA. Additionally, protein-protein interaction network of these target genes was mainly enriched in dynein intermediate chain binding, cell division, regulation of cell cycle process, and positive regulation of cellular component biogenesis. CONCLUSIONS: The results suggests that miR-223 and its targets, ANLN, DYNLT1, LRRC59, SLC12A8 and TPM3, might be reliable potential prognostic biomarkers in BRCA patients.

RESUMO

Background: This study aims to examine the relationship between the development of coronary collateral circulation and serum elabela levels. Methods: Between January 2020 and December 2021, a total of 50 control individuals (29 males, 21 females; mean age: 63.2±10.0 years; range, 52 to 73 years) with no significant coronary artery disease as confirmed by angiography (Group 1) and 100 patients (55 males, 45 females; mean age: 66.6±9.6 years; range, 56 to 75 years) with coronary artery disease were included. The patients were further divided into two equal groups according to the Rentrop classification as poor (Group 2) and good coronary collateral circulation (Group 3). All groups were compared in terms of several parameters, particularly serum elabela levels. Results: Serum elabela levels were found to be statistically higher in the group with good collateral than the other groups (p<0.05). Low serum elabela levels increased the risk of developing weak collaterals by 2.43 times. Conclusion: The elabela protein is directly related to good collateral development and can be considered a potential agent for treatment.

RESUMO

BACKGROUND: Duodenal ulcer perforation is a serious condition. A number of methods have been defined and used in surgical treatment. In this study, it was aimed to compare the effectiveness of 'primary repair' and 'drain placement without repair' methods in duodenal perforations using an animal model. METHODS: Three equivalent groups of ten rats each were formed. Perforation was created in the duodenum in the first (primary repair/sutured group) and the second group (drain placement without repair/sutureless drainage group). In the first group, the per-foration was repaired with sutures. In the second group, only a drain was placed in the abdomen without sutures. In the third group (control group), only laparotomy was performed. Neutrophil count, sedimentation, serum C-reactive protein (CRP), serum total an-tioxidant capacity (TAC), serum total thiol, serum native thiol, and serum myeloperoxidase (MPO) analyses were performed on animal subjects in the pre-operative period and on the post-operative 1st and 7th days. Histological and immunohistochemical (transforming growth factor-beta 1 [TGF-ß1]) analyzes were performed. Blood analysis, histological, and immunohistochemical findings obtained from the groups were compared statistically. RESULTS: There was no significant difference between the first and second groups, except for the TAC on the post-operative 7th day and MPO values on the post-operative 1st day (P>0.05). Although tissue healing was more pronounced in the second group than in the first group, there was no significant difference between the groups (P>0.05). TGF-ß1 immunoreactivity observed in the second group was found to be significantly higher than in the first group (P<0.05). CONCLUSION: We think that the sutureless drainage method is as effective as the primary repair method in the treatment of duo-denal ulcer perforation and can be safely applied as an alternative to the primary repair method. However, further studies are needed to fully determine the efficacy of the sutureless drainage method.

RESUMO

Stemming is supposed to improve the average performance of an information retrieval system, but in practice, past experimental results show that this is not always the case. In this article, we propose a selective approach to stemming that decides whether stemming should be applied or not on a query basis. Our method aims at minimizing the risk of failure caused by stemming in retrieving semantically-related documents. The proposed work mainly contributes to the IR literature by proposing an application of selective stemming and a set of new features that derived from the term frequency distributions of the systems in selection. The method based on the approach leverages both some of the query performance predictors and the derived features and a machine learning technique. It is comprehensively evaluated using three rule-based stemmers and eight query sets corresponding to four document collections from the standard TREC and NTCIR datasets. The document collections, except for one, include Web documents ranging from 25 million to 733 million. The results of the experiments show that the method is capable of making accurate selections that increase the robustness of the system and minimize the risk of failure (i.e., per query performance losses) across queries. The results also show that the method attains a systematically higher average retrieval performance than the single systems for most query sets.

RESUMO

AIM: To reveal the relationships between patient findings and tissue resection in elderly patients. MATERIALS AND METHODS: Between September 2020 and September 2022 three hundred eighty four patients over the age of 60 who were operated with the diagnosis of groin hernia were retrospectively analyzed. Gender, age, height, weight and body mass index value, groin and inguinal hernia types, hernia sides, primary or recurrent cases, hernia sac content, incarceration, tissue necrosis and resection presence, and accompanying pathologies were recorded. These findings were compared and evaluated in order to determine the relationships between patient findings and tissue resection, and the findings at risk for tissue resection. RESULTS: Of the patients in the study, 352 (91.7%) were male and 32 (8.3%) were female. The mean age, height, weight and BMI were 67.48±5.893 years, 169.27±6.113 cm, 73.28±7.878 kg and 25,566±2.3518 kg/m2, respectively. There were 369 inguinal, 15 femoral, 285 indirect, 84 direct, 312 primary, and 72 recurrent hernias. Incarceration was present in 65 (16.9%) patients, 19 (4.9%) of these patients underwent resection due to tissue necrosis (twelve omentum and seven small intestine). Tissue resection was 3.1% in male, 25% in female, 4.3% in inguinal, 20% in femoral, 5.6% in indirect, 0% in direct, 3.5% in primary and 11.1% in recurrent hernias. Tissue resections were significantly higher in females, femoral hernias, indirect inguinal hernias and recurrent cases (p<0.05). CONCLUSIONS: We can say that female gender, femoral, indirect and recurrent hernias are important risk factors for tissue resection in elderly patients. KEY WORDS: Elderly Patients, Emergency Surgery, Groin Hernia, Incarceration, Tissue Resection.

RESUMO

PURPOSE: The present study aimed to evaluate the relationship between tumor volume and apparent diffusion coefficient (ADC) in preoperative magnetic resonance imaging and deep myometrial invasion, tumor grade, and lymphovascular space invasion (LVSI) in patients with early-stage endometrial cancer. METHODS: The study included 73 patients diagnosed with early-stage endometrial cancer based on histopathological examination between May 2014 and July 2019. Receiver operating characteristic (ROC) curve analysis was used to estimate the accuracy of ADC and tumor volume in predicting the LVSI, the depth of myometrial invasion (DMI), and the histopathological tumor grade in these patients. RESULTS: The areas under the ROC curves (AUCs) of ADC and tumor volume in predicting LVI, DMI, and high tumor grade were significantly greater than those for superficial myometrial invasion and low-grade tumors. The ROC analysis revealed that higher tumor volume was significantly associated with the prediction of DMI and tumor grade (p = 0.002 and p = 0.015). The corresponding cut-off values of tumor volume were > 7.12 and > 9.38 mL. The sensitivity of ADC in predicting DMI was higher than its sensitivity in predicting LVSI and grade 1 tumors. Furthermore, tumor volume was significantly associated with the prediction of DMI and tumor grade. CONCLUSION: In the absence of pathological pelvic lymph nodes in early-stage endometrial cancer, tumor volume in DWI sequences determines the active tumor load and tumor aggressiveness. Furthermore, a low ADC indicates deep myometrial invasion and helps differentiate stage IA and stage IB tumors.

RESUMO

BACKGROUND: Atrial fibrillation (AF), a condition that might occur after a heart bypass procedure, has caused differing estimates of its occurrence and risk. The current study analyses the possible risk factors of post-coronary artery bypass grafting (post-CABG) AF (postoperative AF [POAF]) and presents a software for preoperative POAF risk prediction. METHODS: This retrospective research was performed on 1,667 patients who underwent CABG surgery using the hospital database. The associations between the variables of the patients and AF risk factors after CABG were examined using multivariable logistic regression (LR) after preprocessing the relevant data. The tool was designed to predict POAF risk using Shiny, an R package, to develop a web-based software. RESULTS: The overall proportion of post-CABG AF was 12.2%. According to the results of univariate tests, in terms of age (p < 0.001), blood urea nitrogen (p = 0.005), platelet (p < 0.001), triglyceride (p = 0.0026), presence of chronic obstructive pulmonary disease (COPD; p = 0.01), and presence of preoperative carotid artery stenosis (PCAS; p < 0.001), there were statistically significant differences between the POAF and non-POAF groups. Multivariable LR analysis disclosed the independent risk factors associated with POAF: PCAS (odds ratio [OR] = 2.360; p = 0.028), COPD (OR = 2.243; p = 0.015), body mass index (OR = 1.090; p = 0.006), age (OR = 1.054, p < 0.001), and platelet (OR = 0.994, p < 0.001). CONCLUSION: The experimental findings from the current research demonstrate that the suggested tool (POAFRiskScore v.1.0) can help clinicians predict POAF risk development in the preoperative period after validated on large sample(s) that can represent the related population(s). Simultaneously, since the updated versions of the proposed tool will be released periodically based on the increases in data dimensions with continuously added new samples and related factors, more robust predictions may be obtained in the subsequent stages of the current study in statistical and clinical terms.

RESUMO

BACKGROUND: Appendicitis is one of the most common surgical emergencies among children. In this retrospective clinical study, we attempted to determine the effects of the COVID-19 pandemic period on hospital admission time and length of hospital stay (LOS) in pediatric appendicitis cases. METHODS: We retrospectively compared pediatric appendectomies from the date of the first reported COVID-19 case to June 1, 2020, which is considered as the start of the normalization process, with pre-pandemic pediatric appendectomies of the same number of days in terms of age, gender, hospital admission time, LOS, parental educational level, laboratory values, and histopathological findings. RESULTS: There was an average increase of 2 days in the time from the onset of symptoms to hospital admission in pediatric appen-dicitis patients in the COVID-19 period (p=0.001). Furthermore, C-reactive protein value was statistically significantly higher in the COVID-19 period (p=0.018). Given the LOS, it was calculated as an average of 5 days in the pre-pandemic period and 4 days in the COVID-19 period, and this difference was statistically insignificant (p=0.273). There was no significant difference between the groups in terms of histopathological findings (p=0.176). The parental educational level had no effect on the admission time. CONCLUSION: The hospital admission time of pediatric appendicitis patients is significantly prolonged in the COVID-19 pandemic, but this prolongation had no histopathological effect. During the pandemic, the recovery of patients who required urgent treatment during the 'stay-at-home' period was also negatively affected. Notwithstanding, we are of the opinion that the absence of an increase in the LOS may be due to the willingness of both families and physicians to keep the LOS as short as possible. Despite the increase in hospital admission time in pediatric appendicitis during the Covid 19 pandemic process, the lack of increase in the rate of complicated appendicitis may be an indicator of the importance of other factors in the development of complicated appendicitis.

RESUMO

TP73 antisense RNA 1 (TP73-AS1) is an oncogenic long non-coding RNA that is activated in several types of cancers. It has been shown that the activity of TP73-AS1 is controlled by several miRNAs, but post-transcriptional mechanisms that regulate TP73-AS1 activity in prostate cancer remain highly elusive. Accordingly, in the present study, we aimed to determine the miRNAs that are involved in the regulation of TP73-AS1 in prostate cancer and to show the effects of these molecules on the malignant proliferation of prostate cancer cells. Remarkably, colony formation and cell migration were suppressed while cell cycle arrest and apoptosis were induced in prostate cancer cells overexpressing miR-200a and miR-320a. miR-200a and miR-320a were found to be upregulated in TP73-AS1 suppressed prostate cancer cells. Also, TP73-AS1 was shown to be downregulated following miR-200a and miR-320a overexpression. However, overexpression of miR-320a had no significant effect on the expression of TP73. Further analysis revealed that miR-320a induces p53-dependent apoptosis. Consequently, our findings indicate that miR-320a induces p53-dependent apoptosis by negatively regulating TP73-AS1 long non-coding RNA.

RESUMO

OBJECTIVE: Fluid overload is associated with increased mortality and morbidity in pediatric cardiac surgery. In the pediatric age group, peritoneal dialysis might improve postoperative outcome with avoiding fluid overload and electrolyte imbalance. It preserves hemodynamic status with the advantage of passive drainage. In this study, we are reporting our results of peritoneal dialysis after cardiac surgery. METHODS: In this retrospective study, we evaluated the patients who underwent pediatric cardiac surgery in our hospital between December 2010 and January 2020. Patients who required peritoneal dialysis during hospitalization period were included in the study. Patients' clinical status and outcomes were evaluated. RESULTS: Peritoneal dialysis was performed to 89 patients during the study period. The age varies from the newborn to 4 years old. The indication of peritoneal dialysis was prophylactic in 68.5% (n=61) and for the treatment in 31.5% (n=28). There were 31 mortalities. The risk factors for the mortality were preoperative lower age, longer cardiopulmonary bypass time, lengthened intubation, lengthened inotropic support, and requirement of extracorporeal membrane oxygenation (p<0.0001). CONCLUSION: Earlier initiation of peritoneal dialysis in pediatric cardiac surgery helps maintain hemodynamic instability by avoiding fluid overload, considering the difficulty in the treatment of electrolyte imbalance and diuresis.

RESUMO

INTRODUCTION: Ischemia/reperfusion injury occurs after testicular torsion, levels of free oxygen radicals and inflammatory cytokines are increased in both the torsional and contralateral testis, leading to testicular injury. OBJECTIVE: The present study investigated whether orchiopexy or orchiectomy after testicular torsion was superior in terms of fertility potential in the long term. STUDY DESIGN: Following 720°, 4 h left testicular torsion, orchiectomy or orchiopexy was performed on 84 rats, which were then sacrificed and evaluated for testicular function at day 1, at 3 months and 6 months (n = 14 per group). An additional 14 rats were in the control group. RESULTS: Follicle stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels were significantly lower in the orchiopexy group than the orchiectomy and control groups after 3 months. However, there were no significant differences in hormone parameters among the three groups after 6 months. The hormone levels, Johnsen score, seminiferous tubule diameter, and inducible nitric oxide synthase (iNOS) expression at 3 and 6 months were not significantly different between the orchiectomy group and controls. Histopathological analyses at 3 and 6 months indicated significant decreases in Johnsen score and seminiferous tubule diameter in the ipsilateral testis in the orchiopexy group. At 3 months, the level of iNOS expression in the contralateral testis was significantly lower in the orchiopexy group than in other groups. At 6 months, however, it was not significantly different between the orchiopexy and control groups. There were no significant differences in iNOS expression at 3 or 6 months in the orchiectomy group compared to controls. DISCUSSION: The ipsilateral testis in the orchiopexy group began to atrophy at 3 months, and the degree of atrophy became more evident at 6 months. The level of iNOS expression was low in the bilateral testis at 3 months in the orchiopexy group, and sperm in the contralateral testis were not yet functionally healthy. The level of iNOS expression in the ipsilateral testis decreased further at 6 months in the orchiopexy group, while that in the contralateral testis returned to the normal level. CONCLUSION: Testicular functions were restored faster after orchiectomy compared to orchiopexy following testicular torsion. However, follow-up of the rats for 6 months demonstrated that orchiopexy or orchiectomy procedures conducted on the testicular torsion had no effect on future fertility potential after 4 h of torsion.

RESUMO

SUMMARY OBJECTIVE: Fluid overload is associated with increased mortality and morbidity in pediatric cardiac surgery. In the pediatric age group, peritoneal dialysis might improve postoperative outcome with avoiding fluid overload and electrolyte imbalance. It preserves hemodynamic status with the advantage of passive drainage. In this study, we are reporting our results of peritoneal dialysis after cardiac surgery. METHODS: In this retrospective study, we evaluated the patients who underwent pediatric cardiac surgery in our hospital between December 2010 and January 2020. Patients who required peritoneal dialysis during hospitalization period were included in the study. Patients' clinical status and outcomes were evaluated. RESULTS: Peritoneal dialysis was performed to 89 patients during the study period. The age varies from the newborn to 4 years old. The indication of peritoneal dialysis was prophylactic in 68.5% (n=61) and for the treatment in 31.5% (n=28). There were 31 mortalities. The risk factors for the mortality were preoperative lower age, longer cardiopulmonary bypass time, lengthened intubation, lengthened inotropic support, and requirement of extracorporeal membrane oxygenation (p<0.0001). CONCLUSION: Earlier initiation of peritoneal dialysis in pediatric cardiac surgery helps maintain hemodynamic instability by avoiding fluid overload, considering the difficulty in the treatment of electrolyte imbalance and diuresis.

RESUMO

The short arm of chromosome 16 and especially the region 16p13.11 is a chromosome region where many structural variants, especially deletions and duplications, can be observed. Although deletions of this region are clinically well defined, duplications are rare, and so far, there is no established clinical consensus in regard with its clinical picture, and especially the dysmorphic perspective of the disease is far from being clear. A 5-year-and-2-month-old patient who presented with epilepsy, autism and late speech onset complaints was evaluated in our genetics department. On physical examination, unilateral preauricular skin tag and upslanting palpebral fissures were noted. Microarray analysis was performed and reported as ([hg19]: 16p13.11 (14.897.804-16.730.375) x3). The literature review revealed only a few reports about the syndrome, but some dysmorphological findings appear to recur in different reports, which enables a possible characterization. Dysmorphic findings were discussed.

RESUMO

BACKGROUND: Bronchopulmonary dysplasia (BPD) carries a risk of long-term pulmonary sequelae. High-resolution computed tomography (HRCT) is a method of detecting such structural changes. This study is aimed at characterizing structural abnormalities associated with BPD and at evaluating the clinical findings in the newborn period associated with HRCT scores. METHODS: 28 patients born with a mean gestation age of 30 ± 2.9 weeks and diagnosed as BPD in their neonatal period were reevaluated when they were between the postnatal ages of 6 and 12 months. HRCT was performed in 20 patients with a history of moderate and severe BPD. Scans were interpreted by one radiologist using a scoring system. RESULTS: Patients were 9.8 ± 2.3 months at the time of reevaluation. The average HRCT score of patients was, respectively, 7.20 ± 4.05 with moderate and 7.40 ± 2.84 with severe BPD. The difference between them was not significant (p = 0.620). When moderate and severe groups were collected as a whole on the basis of physical findings and drug treatment, 6 had normal physical examination findings, no oxygen and no drug requirement; 14 had at least one finding at the time of reevaluation. No significant difference was detected in terms of HRCT score between the two groups (6.50 ± 3.83 versus 7.64 ± 3.30). CONCLUSIONS: More studies are needed in terms of the role of HRCT in the assessment of BPD prognosis. A contemporary definition of BPD that correlates with respiratory morbidity in childhood is needed. Also, a new lung ultrasound technique for predicting the respiratory outcome in patients with BPD can be used instead of HRCT.
