RESUMO

BACKGROUND: This study aimed to investigate whether Passiflora Incarnata (PI) has a protective effect against ischemia-reperfu-sion (IR)-induced oxidative and inflammatory ovarian damage. METHODS: The effects of PI on ovarian ischemia-reperfusion injury were investigated in female Wistar albino rats. The animals were randomly divided into three groups: Group 1 (sham), Group 2 (IR), and Group 3 (IR+PI). RESULTS: The mean levels of Malondialdehyde (MDA), Myeloperoxidase (MPO), and Total Oxidant Status (TOS) were higher in the IR group (p=0.025, p<0.001, and p=0.016, respectively). The Total Antioxidant Status (TAS) levels were lower in the IR group (p=0.005). Immunostaining revealed significant differences across the groups for Tumor necrosis factor-alpha (TNF-α): 13.84%, 49.51%, and 22.51% for Groups 1, 2, and 3, respectively (p<0.01). Bax: 10.53%, 46.74%, and 26.46% for Groups 1, 2, and 3, respectively (p<0.01). Annexin V: 12.24%, 44.86%, and 23.28% for Groups 1, 2, and 3, respectively (p<0.01). The mean scores for hemorrhage, inflammation, follicular degeneration, and congestion showed significant variations among the groups, all registering p<0.001. CONCLUSION: Passiflora Incarnata exhibited antioxidant, anti-inflammatory, and anti-apoptotic properties, promoting cell survival, histologically protecting ovarian tissue, and ameliorating IR injury by reducing oxidative stress.

RESUMO

OBJECTIVE: In this study, we present our extracorporeal shock wave lithotripsy (ESWL) outcomes in urolithiasis patients under the age of two. MATERIALS AND METHODS: The procedure was performed with patients < 2 years of age sedated, under anesthesia using ketamine and Dormicum (midazolam), in the supine position. Fragmentation was evaluated by fluoroscopy after the procedure. RESULTS: A total of 74 procedures were performed on 65 kidneys. One patient with bilateral stones had two sessions of ESWL on the right side; three sessions of ESWL were performed in one patient with a unilateral stone, and two sessions were performed in seven patients with unilateral stones. All other patients underwent one session of ESWL. As post-procedural complications, hematuria was observed in 14 patients (12 mild and 2 significant), and vomiting occurred in 1 patient. Ureterorenoscopy was performed in 5 patients, and percutaneous nephrolithotomy in 6 patients due to a failed procedure. CONCLUSION: As a result, ESWL treatment is effective and has advantages such as a short hospitalization time, good reproducibility, cost-effectiveness, and a low rate of complications. Therefore, we recommend ESWL as the first-line treatment for renal and proximal ureteral stones in infants < 2 years of age.


OBIETIVO: En este estudio, presentamos nuestros resultados de ESWL en pacientes con urolitiasis menores de dos años. MATERIALES Y MÉTODOS: El procedimiento se realizó con pacientes menores de dos años sedados, bajo anestesia con ketamina y Dormicum (midazolam), en posición supina. La fragmentación se evaluó mediante fluoroscopia después del procedimiento. RESULTADOS: Se realizaron total de 74 procedimientos en 65 riñones. Un paciente con cálculos bilaterales tuvo dos sesiones de ESWL en el lado derecho; se realizaron tres sesiones de LEOC en un paciente con litiasis unilateral y dos sesiones en siete pacientes con litiasis unilateral. Todos los demás pacientes se sometieron a una sesión de ESWL. Como complicaciones post-procedimiento se observó hematuria en 14 pacientes (12 leves y 2 significativas) y vómitos en 1 paciente. Se realizó URS en 5 pacientes y NLP en 6 pacientes debido a un procedimiento fallido. CONCLUSIONES: Como resultado, el tratamiento de la ESWL es efectivo y tiene ventajas como un tiempo de hospitalización corto, buena reproducibilidad, costo-efectividad y baja tasa de complicaciones. Por tanto, recomendamos la ESWL como tratamiento de primera línea para cálculos renales y ureterales proximales en bebés < 2 años de edad.

RESUMO

BACKGROUND: Ursolic acid (UA) is found in many plants, and has been reported to have anti-protease, antioxidant, anti-inflammatory, antimicrobial, nephroprotective, hepatoprotective, and cardioprotective effects. OBJECTIVE: The purpose of this study was to investigate the effects of ursolic acid in cerulein-induced acute pancreatitis (AP). MATERIALS AND METHODS: Thirty-two Wistar albino rats were randomly assigned to 4 equal groups: Sham, acute pancreatitis, treatment, and ursolic acid group. RESULTS: Serum amylase levels in the AP and treatment groups were significantly higher than in the others (p < 0.05). In addition, serum IL-1ß, IL-6, and TNF-α levels were significantly higher in the AP group in comparison with the treatment group. Although pancreatic tissue total oxidant activity in the AP and treatment groups was similar, pancreatic tissue total antioxidant capacity was significantly higher in the treatment group than in the AP group. CONCLUSIONS: Damage to the pancreas and remote organs in AP was observed to be reduced by UA. In addition, oxidative stress was observed to be decreased by the effect of UA.


ANTECEDENTES: El ácido ursólico se encuentra en numerosas plantas y se ha informado que tiene efectos antiproteasas, antioxidantes, antiinflamatorios, antimicrobianos, nefroprotectores, hepatoprotectores y cardioprotectores. OBJETIVO: Este estudio tuvo como objetivo investigar los efectos del ácido ursólico en la pancreatitis aguda inducida por ceruleína. MATERIAL Y MÉTODOS: Treinta y dos ratas albinas Wistar fueron asignadas aleatoriamente a cuatro grupos iguales: grupo simulado, grupo de pancreatitis aguda, grupo de tratamiento y grupo de ácido ursólico. RESULTADOS: Los niveles de amilasa sérica en los grupos de pancreatitis aguda y de tratamiento fueron significativamente más altos que en los otros grupos (p < 0.05). Además, los niveles séricos de IL-1ß, IL-6 y TNF-α fueron significativamente más altos en el grupo de pancreatitis aguda en comparación con el grupo de tratamiento. Aunque la actividad oxidante total del tejido pancreático en ambos grupos fue similar, la capacidad antioxidante total del tejido pancreático en el grupo de tratamiento fue significativamente mayor. CONCLUSIÓN: Se observó que el ácido ursólico reduce el daño al páncreas y órganos remotos en la pancreatitis aguda, al igual que el estrés oxidativo.

RESUMO

BACKGROUND/PURPOSE: This study analyzed factors that affect mortality in patients surgically treated for EA, then explored the long-term problems encountered by these patients. MATERIALS AND METHODS: Among 252 patients with EA who were either diagnosed, treated, and subsequently followed at the Department of Pediatric Surgery, Dicle University Medical Faculty Hospital, or were treated surgically elsewhere but followed at our center, between January 2010 and January 2020,214 patients were included in the study. RESULTS: Early complications:One or more early complications were observed in 132(62.5%) of the 211 patients who underwent surgical EA repair. The most common early complication was AS, which developed in 106(50.2%) patients. Anastomosis leakage. Was detected in 48 (22.7%) patients. Late complications: The late findings of 161 patients who underwent definitive surgery and had a mean follow-up period of 68 months (range, 6-120 months) were evaluated. The most common late complication was GER. MORTALITY: Of the 214 patients in our study, 63(29.4%) died, including 48(76.2%) during the early period after the first surgery. Of the 10(15.9%) patients who died during the late period. CONCLUSION: In our study, the most common early complication was anastomotic stenosis in patients with esophageal atresia. We recommend balloon dilation in the treatment of anastomotic stenosis.Gastroesophageal reflux is the most common long-term complication. Most of these can be treated conservatively and medically. The association of low birth weight, cardiac anomalies, prematurity and VACTERL increased mortality in patients with esophageal atresia in our study. KEY WORDS: Esophageal Atresia, Morbidity, Late Period, Mortality, Tracheoesophageal Fistula.

RESUMO

OBJECTIVE: We aimed to assess the evidence on the efficacy and safety of transanastomotic feeding tubes (TAFTs) in neonates with congenital duodenal obstruction (CDO), we conducted a systematic review. MATERIAL AND METHODS: Using the databases EMBASE, PubMed, and Cochrane, we carried out a thorough literature search up to 2022. Studies comparing TAFT + and TAFT - for CDO were included. We applied a random effect model. RESULTS: 505 CDO patients who met the inclusion criteria were selected. The TAFT + group had a shorter time to reach full feeds (weighted mean difference [WMD]: -6.63, 95% confidence interval [CI]: -8.83 - -4.43; p < 0.001) and had significantly less central venous catheter (CVC) insertion (I2 = 85%) (RR: 0.43, 95% CI: 0.19-1.00; p < 0.05). Fewer patients in the TAFT + group received parenteral nutrition (PN) (I2 = 78%) (RR: 0.43, 95% CI: 0.20-0.95; p < 0.05). There was no statistically significant difference in terms of the development of sepsis (I2 = 37%) (risk ratio [RR]: 1.35, 95% CI: 0.52-3.46; p > 0.05). No statistically significant difference was observed in terms of length of stay (I2 = 82%) (WMD: 2.22, 95% CI: -7.59-12.03; p > 0.05) and mortality (I2 = 0%) (RR: 0.55, 95% CI: 0.07-4.34; p > 0.05). CONCLUSIONS: The use of the transanastomotic tube resulted in early initiation of full feeding, less CVC insertion, and less need for PN.


OBJETIVO: Nuestro objetivo fue evaluar la evidencia sobre la eficacia y seguridad de TAFT en recién nacidos con CDO, realizamos una revisión sistemática. MATERIAL Y MÉTODOS: Utilizando las bases de datos EMBASE, PubMed y Cochrane, realizamos una búsqueda bibliográfica exhaustiva hasta 2022. Se incluyeron estudios que compararan TAFT + y TAFT - para CDO. Aplicamos un modelo de efectos aleatorios. RESULTADOS: Se seleccionaron 505 pacientes con ODC que cumplían con los criterios de inclusión. El grupo TAFT + tuvo un tiempo más corto para alcanzar la alimentación completa (DMP -6.63, IC del 95 %: −8.83 a −4.43; p < 0.001) y tuvo una inserción de CVC significativamente menor. Menos pacientes en grupo TAFT + recibieron NP (I2 = 78%) (RR: 0.43, IC del 95%: 0.20 a 0.95; p < 0.05). No hubo diferencia estadísticamente significativa en cuanto al desarrollo de sepsis. No se observaron diferencias estadísticamente significativas en cuanto a la duración de la estancia (I2 = 82 %) (DMP 2.22, IC del 95 %: −7.59 a 12.03; p < 0.05) y mortalidad (I2=0 %) (RR: 0.55, IC del 95 % 0.07 a 4.34; p > 0.05). CONCLUSIONES: El uso de la sonda transanastomótica resultó en el inicio temprano de la alimentación completa, menor inserción de CVC y menor necesidad de NP.

RESUMO

BACKGROUND: Acute appendicitis diagnosis can sometimes be a real challenge in pediatric patients. OBJECTIVE: To establish the importance of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and other hematological parameters adjusted for age and sex in the prediction of acute appendicitis, as well as to describe a new scoring system. MATERIAL AND METHODS: Medical records of 946 children hospitalized for acute appendicitis were retrospectively analyzed. A scoring system based on NLR, PLR, lymphocyte/monocyte ratio (LMR), and C-reactive protein (CRP) adjusted for age and sex was developed. RESULTS: Patients were divided into group I, with negative examination, and group II, with acute appendicitis; mean ages were 12.20 ± 2.31 and 11.56 ± 3.11, respectively. Leukocyte count, neutrophil percentage, NLR, PLR, LMR and PCR were higher in group II. The scores ranged from 0 to 8 points; 4.5 was determined to be the best cut-off point for acute appendicitis with the highest area under the curve (0.96), sensitivity (94%), specificity (86%), positive predictive value (97.5%), negative predictive value (65%), accuracy (92.6%) and misclassification rate (7.4%). CONCLUSION: The proposed scoring system, calculated based on patient age and gender, can be used for unnecessary surgeries to be avoided.


ANTECEDENTES: El diagnóstico de apendicitis aguda representa un reto en pacientes pediátricos. OBJETIVO: Establecer la importancia del índice neutrófilos-linfocitos (INL), índice plaquetas-linfocitos (IPL) y otros parámetros hematológicos ajustados por edad y sexo en la predicción de apendicitis aguda, así como describir un nuevo sistema de calificación. MATERIAL Y MÉTODOS: Se analizaron retrospectivamente expedientes clínicos de 946 niños hospitalizados por apendicitis aguda. Se desarrolló un sistema de calificación basado en INL, IPL, ILM y proteína C reactiva (PCR) ajustados por edad y sexo. RESULTADOS: Los pacientes se dividieron en grupo I de exploración negativa y grupo II de apendicitis aguda; las medias de edad correspondientes fueron 12.20 ± 2.31 y 11.56 ± 3.11. El recuento leucocitario, porcentaje de neutrófilos, INL, IPL, ILM y PCR fueron superiores en el grupo II. La calificación osciló entre 0 y 8 puntos; se determinó que 4.5 fue el mejor punto de corte para apendicitis aguda con mayor área bajo la curva (0.96), sensibilidad (94 %), especificidad (86 %), valor predictivo positivo (97.5 %), valor predictivo negativo (65 %), precisión (92.6 %) y tasa de clasificación errónea (7.4 %). CONCLUSIÓN: El sistema de calificación que se propone, calculado por edad y sexo de los pacientes, se puede utilizar para evitar cirugías innecesarias.

RESUMO

OBJECTIVE: Our goal was to compare single-incision laparoscopic percutaneous and cystoscope forceps-assisted Morgagni hernia repair techniques. MATERIALS AND METHODS: A total of 40 patients were allocated to two groups, each with 20 patients. Group 1: Single incision (port) laparoscopic surgical percutaneous Morgagni hernia repair (with a 5 mm Storz laparoscopic scope entered through the umbilicus). Group 2: Single incision (port) laparoscopic surgical percutaneous Morgagni hernia repair (with an 11 Fr [3.6 mm] cystoscope entered through the umbilicus + using forceps + sac plication, and sac cauterization). In Group 1; the sac was not removed. In group 2; we advanced the forceps through the cystoscope, caught the sac, pushed the needle through the sac, plicated the sac, and then cauterized the sac with Bugbee electrode. RESULTS: Of the 40 patients, 70 % (n = 28) were male. The symptoms at admission included repeated chest infections (40 %), dyspnea (30 %), vomiting (22 %), and abdominal pain (22 %). No difference was found between groups in terms of age, gender symptomatology, or associated anomalies. The operation time was shorter in group 2 compared to group 1 (p < 0.05; 25 min vs 40 min). Although there was one recurrence in Group 1, no recurrence was reported in Group 2. The recurrence incidence did not differ between groups (p > 0.05). CONCLUSIONS: Cystoscope-assisted repair of Morgagni hernia was found to be superior in terms of safety and shorter operation time. LEVEL OF EVIDENCE: Type III. TYPE OF THE STUDY: Retrospective study.

RESUMO

OBJECTIVE: None of studies have been conducted in terms of demonstrating the same effect with the low dose in cordycepin. In our study, we analyzed the histopathological and biochemical changes of low-dose Cordycepin(c) on a rat model in the kidney. MATERIALS AND METHODS: Twenty-four male Wistar Albino rats were randomly allocated to three groups (n = 8): the sham-control group (Group 1), the renal I/R-untreated (Group 2) group, and the I/R-C-treated (Group 3) group. Cordyceps was administered intraperitoneally at 5 mg/kg twice. Renal histological changes were compared and the relevant parameters of oxidative stress and inflammation were detected. RESULTS: In blood and tissue biochemistry, it was observed that IL-1 Beta, IL 6, TNF alpha, MDA, TOS, and OSI increased in Group 2 and decreased in Group 3. It was determined that TAS values were increased in Group 3, and decreased in Group 2. In the histopathological evaluation, while Group 1 was evaluated as normal, significant kidney damage was detected in Group 2. It was determined that there was a significant decrease in kidney damage in Group 3. CONCLUSION: These results suggest that low dose Cordycepin was as effective as normal dose on renal ischemic reperfusion and reduction of damage.


OBJETIVO: Ninguno de los estudios se ha realizado en términos de demostrar el mismo efecto con la dosis baja de cordicepina. En nuestro estudio, analizamos los cambios histopatológicos y bioquímicos de Cordycepin(c) en dosis bajas en un modelo de rata con isquemia-reperfusión (I/R) inducida en el riñón. MATERIALES Y MÉTODOS: Veinticuatro ratas macho Wistar Albino se asignaron al azar a tres grupos (n = 8): el grupo de control simulado (Grupo 1), el grupo sin tratamiento I/R renal (Grupo 2) y el grupo tratado con I/R-C (Grupo 3). Cordyceps se administró por vía intraperitoneal a 5 mg/kg dos veces. Se compararon los cambios histológicos renales y se detectaron los parámetros relevantes de estrés oxidativo e inflamación. RESULTADOS: En bioquímica sanguínea y tisular se observó que IL-1 Beta, IL 6, TNF alfa, MDA, TOS y OSI aumentaron en el Grupo 2 y disminuyeron en el Grupo 3. Se determinó que los valores de TAS aumentaron en el Grupo 3, y disminuyó en el Grupo 2. En la evaluación histopatológica, mientras que el Grupo 1 fue evaluado como normal, se detectó daño renal significativo en el Grupo 2. Se determinó que hubo una disminución significativa del daño renal en el grupo 3. CONCLUSIÓN: Estos resultados sugieren que la cordicepina en dosis bajas fue tan efectiva como la dosis normal en la reperfusión isquémica renal y la reducción del daño.

RESUMO

BACKGROUND: The aim of this study was to present our experience in the use of crystallized phenol (CP) to treat pediatric patients with 'simple' and complex' Pilonidal sinus disease (PSD). MATERIALS AND METHODS: Patients who underwent CP treatment in between January 2015 and January 2020 were evaluated retrospectively, using prospectively collected data. The patients were divided into simple and complicated groups. The groups were assigned depending on the number of sinuses and clinical presentation. The groups were compared in terms of age, sex, number of sessions, cost analysis, body mass index (BMI), recurrence, time resolution, cosmetic results, results /improvement, and complications. RESULTS: This study included 54 patients: 28 (52%) girls and 26 (48%) boys. The mean number of sinuses was 2.4. Symptoms included discharge in 50 (92%) patients, and pain in 42 (78%) patients. Fifty (93%) patients experienced mild pain during the procedure, whereas four (7%) patients had moderate pain. The mean number of CP sessions was 2.9; mean numbers of CP sessions were 2.2 and 4.2 in the Simple and Complicated groups. In total, 5 of 54 patients (9%) had recurrence.At the end of treatment, therapeutic success was achieved in 49 of 54 (91%) patients: 31 of 33 (94%) patients in the Simple group and 18 of 21 patients (86%) in the complicated group. The mean treatment cost for the whole cohort was $17.40. One patient (2%) presented with moderate skin burns. Cosmesis was deemed acceptable by patients, although there was evidence of minor skin burns following the procedure. CONCLUSIONS: The findings showed that the CP procedure was advantageous for treatment of PSD, because it was minimally invasive, cost-effective, provided good cosmesis, and had a high success rate and low complication rate. Furthermore, it did not require prior examination, and could be performed under local anesthesia. Therefore, the CP procedure may be useful as a first-line treatment option in children with PSD.

RESUMO

BACKGROUND: In this study, we aimed to present the results of patients treated for esophageal leakage with a different conservative approach. METHODS: Ninety-eight patients with esophageal atresia and tracheoesophageal fistula (EA) who underwent surgery in our clinic between February 2013 and January 2018 were retrospectively reviewed in this study. Patients' anastomosis leakage, gestational week, gender, body weight, referral date, recovery time and stenosis were recorded. After leakage detection, the nasogastric catheter was fluoroscopically converted into a nasojejunal catheter using a guidewire and feeding continued. RESULTS: Anastomotic leakage developed in 18 (18.3%) patients. The average gestational age at birth was 35.4 weeks; the patients included ten girls and eight boys of average weight 2.41 kg; the average referral period was 2.1 days after birth and the average time of surgery was 2.4 days after birth. The average recovery time was 21.1 days (range: 8-60 days). Eight patients developed stenosis that recovered with dilatation. CONCLUSION: Our findings suggest that our conservative treatment approach, which uses a nasojejunal catheter, is an effective method that would reduce complications, enable earlier feeding, and reduce the cost compared to other treatment approaches.

RESUMO

In this study, a novel osmotic membrane was developed by polyamide (PA) coating on the tubular electrospun nanofiber (TuEN) support membrane. Water and reverse salt flux properties of the obtained membrane were investigated by applying pressure in addition to the osmotic forces. Surface characterization of the membrane was carried out by Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) analyses and flux performance tests were performed in both cross flow and submerged membrane setups. Applying pressure from the feed to the concentrate side had significant effects on the water and salt fluxes. Higher pressure differences between the feed and concentrate sides resulted in unexpected high water fluxes up to 500 Lm-2h-1 (LMH). Besides, the pressure helps to transfer the salt content of feed water into the concentrate side, differently from the osmotic process preventing the salinity build-up at the feed side. PA coated TuEN membrane operated under pressure will exhibit a favorable solution in water/wastewater treatment applications, especially for membrane bioreactors (MBR) in terms of preventing salt accumulation in the bioreactor, decreasing the membrane fouling, increasing the volume of product water, and enabling the concentrate management.

RESUMO

BACKGROUND: Non-operative management (NOM) is a standard treatment method for solid organ injuries worldwide. There is no consensus on the management of gunshot wounds (GSW) because of the higher frequency of hollow viscus injuries (HVI) and the unpredictable depth of tissue damage produced by kinetic energy transfer during retardation of the bullet. Here we aimed to reevaluate indications for surgery and NOM based on our pediatric patients with abdominal GSW. METHODS: We performed a retrospective analysis of patients evaluated and treated for abdominal GSW at University of Dicle between January 2010 and October 2016. Patients with hemodynamic instability, signs of peritonitis on serial abdominal examination, and free air in the abdomen underwent laparotomy; these were included in group I (n=17). Patients managed non-operatively were included in group II (n=13). RESULTS: Our statistical analysis showed significantly lower Hb levels and systolic blood pressure levels (p<0.001) and higher pulse rate, higher mean injury severity score, and longer length of stay at intensive care unit in patients in group I than in those in group II (p<0.001). We further detected colon perforation (n=10) and small bowel perforation (n=7) in patients in group I; liver laceration (n=4), splenic injury (n=1), and renal injury (n=3) but no solid organ injury or HVI (n=5) were detected in patients in group II. CONCLUSION: The major drawback of NOM is the difficulty in diagnosing HVI in abdominal GSW, which may delay treatment. We suggest that patients with solid organ damage who are hemodynamically stable and exhibit no signs of peritonitis upon serial abdominal exam may be treated with NOM.

RESUMO

OBJECTIVE: To investigate the role of cordycepin in testicular ischemia/reperfusion injury in rats. MATERIALS AND METHODS: Forty Wistar albino rats were randomly divided into four groups, as follows: group one, control (C); group two, torsion and ischemia (I); group three: detorsion with ischemia-reperfusion (IR); and group four, detorsion/cordycepin. The rats were then analyzed macromorphologically and histopathologically, and blood tests were performed. Specifically, the total oxidant status (TOS) and total antioxidant status (TAS) were determined, and malondialdehyde (MDA), tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1ß levels were analyzed. In addition, pyknotic nuclei, spermatozoa, edema, and hemorrhage were assessed. RESULTS: When the IR and cordycepin groups were compared with the other groups, there was a statistically significant decrease in TNF-α and MDA levels (p < 0.05). Increased TAS levels were observed in the cordycepin group compared with the control group. TOS levels were significantly increased in the I and IR groups, but decreased in the cordycepin group (p < 0.05). Similar effects were observed in tissue biochemistry analysis. Histopathological evaluations revealed that the spermatozoa count was decreased in the I and IR groups. However, there was an increase in the cordycepin group, as well as a statistically significant difference between the IR and cordycepin groups (p < 0.01). Finally, edema and inflammation were increased in the I and IR groups, but decreased in the cordycepin group. CONCLUSIONS: Histological and biochemical findings revealed that cordycepin protected against IR-induced testicular injury.

RESUMO

Divarci E, Arslan S, Dökümcü Z, Kantar M, Demirag B, Öniz H, Ertan Y, Alper H, Erdener A, Özcan C. Radiological nodule behavior: A critical parameter in the surgical management of pediatric pulmonary metastases. Turk J Pediatr 2018; 60: 372-379. Radiological nodule behavior (RNB) means the course of nodule appearance on consecutive CT scans. In this study, we aimed to discuss the effects of RNB on prognosis of patients with pulmonary metastasis. Retrospective analysis of patients who underwent pulmonary metastasectomy (PM) between 2005-2015 was performed. RNBs were grouped as stable, enlarging or new rising nodules. The effects of RNBs were analyzed on recurrence, 1- and 3-year event free survival (EFS) and mortality. Twenty-seven patients (18 male) underwent PM with a median age of 15 years (3-18 years). The diagnoses were listed as osteosarcoma (13), Wilms` tumor (7), Ewing`s sarcoma (3), synovial sarcoma (2), rabdomyosarcoma (1) and mixed germ cell tumor of testis (1). RNBs were new rising in 15 patients (55%), enlarging in seven patients (26%) and stable in five patients (19%). Vital tumor metastasis was detected in all of the patients with enlarging nodules (100%); in 10 of the 15 patients with new rising nodules (66%) and none of the patients with stable nodules. None of the patients with stable nodules developed recurrence or died after PM (p˂0.05). In patients with enlarging nodules, metastases recurred and they died in the postoperative period. These findings were similar in different types of tumors. RNB could be used as a critical parameter in deciding surgical management strategies of pulmonary metastases. Stabile nodules should be observed by close follow-up with serial CT scans without surgery. All of the suspected new rising nodules should undergo surgical sampling to avoid unnecessary chemotherapy. Nodule progression under chemotherapy is a poor prognostic criteria for overall survival.

RESUMO

OBJECTIVE: Thoracoscopic treatment of pulmonary hydatid cyst (PHC) has been considered to be a good treatment option in both children and adults for nearly 25 years. However, there have been very few pediatric studies published during this period. Our goal is to review our results and evaluate the efficiency of thorascopy in pediatric patients. MATERIALS AND METHODS: The medical records of patients with PHC who were surgically treated between 2005 and 2015 were reviewed. As all cysts larger than 5 cm in diameter were surgically removed, cysts less than 5 cm in diameter were medically treated and were not included in the study. Demographics, cyst characteristics, and operative/postoperative data were compared between patients who underwent thorascopy (thoracoscopy group) and patients who underwent thoracotomy (thoracotomy group). Chi-square and t-test were used for statistical analysis where appropriate. RESULTS: There were 26 consecutive children (14 girls, 12 boys; mean age 9.4±2.7) included in the study. Except for 2 incidentally diagnosed patients, all were symptomatic, 4 had multifocal lesions, and multiorgan involvement was detected in 11 patients. Thoracoscopy was performed in 10 patients, and conversion was necessary in 2 patients due to unsuccessful fistula ligation attempts. The thoracoscopy group included 8 thoracoscopically treated patients, and remaining patients constituted the thoracotomy group (n=18). Comparison of preoperative characteristics of the groups was insignificant, whereas the overall complication rate (residual bronchial fistula, prolonged air leak, pneumothorax, and localized air cyst) and median hospital stay were significantly higher in the thoracoscopy group. There was no mortality and no recurrence at the postoperative follow-up after 37.4 months. CONCLUSION: The thoracoscopic approach to PHC may have a high risk of conversion and postoperative complication rate. Thoracotomy in children still seems to be the approach of choice for PHC larger than 5 cm. Routine thoracoscopic hydatid cyst treatment is yet far from being the gold standard, whereas thoracoscopy may be preferred in selected patients.

RESUMO

BACKGROUND: The aim of the present study was to investigate whether cordycepin prevented adhesion formation in a rat model. METHODS: Rats were randomly assigned to 3 groups of 10 rats. CONTROL GROUP: The absence of adhesion was confirmed via laparotomy. Adhesion group: The cecum was removed from the abdomen and scraped with a dry gauze bandage until petechial hemorrhagic foci developed. Cordycepin group: The same surgical procedure was performed as in the adhesion group, and 10 mg/kg cordycepin was administered intraperitoneally. After 15 days, the rats were sacrificed humanely via cardiac blood withdrawal under anesthesia. The rats were then analyzed morphologically and histopathologically, and hydroxyproline (OH-p) and malondialdehyde (MDA) levels were measured. RESULTS: Macroscopic analysis revealed significantly less adhesion in the cordycepin group than in the adhesion group (p<0.01). Furthermore, significant histopathological improvement was also evident in the cordycepin group compared to the adhesion group (p<0.05). The levels of OH-p and MDA in blood and tissue were higher in the adhesion group than in the control group, and lower in the cordycepin group than the adhesion group. Interestingly, MDA level was significantly lower (blood: p<0.05; tissue: p<0.01) in the cordycepin group than in the adhesion group, whereas only tissue OH-p was significantly lower in the cordycepin group compared with the adhesion group (p<0.05). One rat in both adhesion group and cordycepin group died postoperatively. CONCLUSION: Results indicated that cordycepin effectively reduced adhesion in a rat abrasion model. Thus, this agent may be valuable to prevent postoperative adhesion.
