RESUMO

Our objective is to analyse the observations related to intrauterine volvulus and assess how clinical manifestations and treatment strategies impact prognosis. We conducted a comprehensive search on Pubmed and ClinicalTrials.gov from inception to July 2022, using search terms like "intrauterine volvulus" or "foetal volvulus," supplemented by manual scrutiny of reference lists in relevant texts and articles. Our review encompassed 57 case reports/case series, involving 88 cases. The presence of foetal bradycardia during prenatal visits (p = 0.002) and the existence of meconium cyst or pseudocyst (p = 0.038) significantly influence survival rates. Preterm labour occurred more frequently among cases resulting in mortality (54% vs 21%; p = 0.055). Our study's limitations include the inability to access all reported cases and reliance solely on available data. We advocate for vigilant monitoring of foetuses exhibiting signs of intestinal obstruction, and consideration of an emergent caesarean section as a pre-emptive measure before foetal biophysical profile deterioration worsens.

RESUMO

BACKGROUND: Lymphadenopathy (LAP) is a common finding in pediatric patients. It was aimed to determine predictive factors in distinguishing cases with malignant or benign lymphadenopathy in this study. SUBJECTS AND METHODS: Between January 2022 and January 2023, 101 patients (1-16 years old) with lymphadenopathy were retrospectively examined. RESULTS: LAP was localized in 80.2% (n=81) cases and generalized in 19.8% (n=20) cases. In 60 cases (59.4%), lymph node sizes were found to be greater than 20×20 mm in width and length. The most common infectious causative agent was Epstein Barr Virus (EBV). Seven (6.9%) patients underwent biopsy and all were diagnosed with malignancy. When the benign and malignant groups were compared, age, lymph node length, and width on physical examination, anteroposterior and longitudinal diameter of the lymph node on ultrasonography (USG) were statistically significantly higher in the malignant group (p<0.05). The presence of supraclavicular lymphadenopathy was found to be an important factor in differentiating the malignant group (p<0.003). The most important factors in distinguishing the groups are respectively were the anteroposterior diameter of the lymph node on ultrasonography and the presence supraclavicular lymph node in multivariate logistic regression analysis. CONCLUSION: It is not always easy to distinguish benign and malignant etiologies in patients with lymphadenopathy. A detailed history, a careful physical examination, laboratory studies, and excisional biopsy are guiding.

RESUMO

BACKGROUND: Mass lesions of the umbilical cord are rare anomalies. There have been rare reports of hemangiomas of the umbilical cord, but the co-occurrence of omphalocele and hemangioma of the umbilical cord has not been previously reported. Nonetheless, the condition is clinically significant as it may cause the disturbance of intrauterine fetal circulation, retardation of fetal growth and development, non-immune hydrops fetalis, morbidity and mortality. CASE: Here we aim to report a case that was prenatally diagnosed with an omphalocele and that presented after birth with a hemangioma on the omphalocele sac. CONCLUSIONS: When dealing with umbilical mass lesions in the prenatal and postnatal periods, a hemangioma on the omphalocele sac should be considered in the differential diagnosis of patients when an omphalocele is suspected.

RESUMO

INTRODUCTION: This study aimed to compare the results of classical surgery (CS) and optical forceps-assisted single-port laparoscopic percutaneous internal ring suturing (SP-PIRS) repair for the treatment of Morgagni hernia. MATERIALS AND METHODS: Patients with Morgagni hernia who were operated on between January 2005 and July 2020 were included in the study. Patients were divided into two groups (CS or SP-PIRS) and compared retrospectively in terms of demographic data, defect size, duration of hospitalization, costs, postoperative complications, and recurrence. RESULTS: Thirty-two patients were included in this study. There were no statistically significant differences between the groups in terms of gender, defect size, postoperative complications, and recurrence (p > 0.05). The SP-PIRS group had a shorter operation time (p < 0.01), shorter hospital stay (p = 0.02), and lower cost (p < 0.01) than the CS group. The average follow-up was 24 months, and recurrence was detected in two patients in each group. CONCLUSION: SP-PIRS repair is recommended because it is practical to perform and reduces the duration of surgery, hospital stay, and cost. It is superior to other laparoscopic techniques, as there is no need to use additional study forceps, except in extreme cases, and the surgeon can perform the procedure without an assistant to hold the laparoscope.

RESUMO

The present study aimed to investigate the bioactive compounds in artichoke (Cynara scolymus) powder, having antioxidant and antimicrobial activity, and to determine the effectiveness of artichoke (C. scolymus) powder extract within the minced meat. C. scolymus was extracted using two different methods. The method incorporating high phenolic and flavonoid content levels was used in other analyses and the phenolic and flavonoid contents in C. scolymus extract was determined using LC-QTOF-MS. Antioxidant, antimicrobial, and metmyoglobin (metMb) reducing activities and pH values of the extract-added minced meat samples were measured for 10 days during storage. DPPH, FRAP, and ABTS were used in the antioxidant analyses. The antimicrobial activity of C. scolymus extract was evaluated on five different food pathogens by using the disc diffusion method. The most resistant bacterium was found to be Listeria monocytogenes (18.05 mm ± 0.24). The amount of metMb was measured in the minced meat sample that was added to the extract during storage (p < 0.05). MetMb formation and pH value on the sixth day of storage were found to be at lower levels than in the control group. In conclusion, C. scolymus exhibited a good antimicrobial and antioxidant effect and can be used in storing and packaging the food products, especially the meat and meat products.

RESUMO

AIM: Trauma is the most common cause of death in childhood. Tissue damage, ischaemia-reperfusion injury and inflammatory response are mainly responsible for increasing free oxygen radicals. In this study, we aimed to investigate the use of thiol-disulphide and ischaemia-modified albumin levels as a diagnostic laboratory parameter in trauma children. METHODS: Of 202 children, 101 were hospitalised in the paediatric surgical intensive care unit with trauma, and 101 were healthy children. Levels of native thiol (-SH), total thiol (SH + SS), dynamic disulphide (SS), dynamic disulphide (SS)/total thiol (SH + SS), albumin and ischaemic modified albumin (IMA) were measured from the sera of patients and healthy volunteers. For statistical analyses, SPSS 17.0 was used. Mann-Whitney U and paired correlation tests were used where appropriate. P < .05 was considered significant. RESULTS: The mean age of the patients in the trauma group (boys: 61 girls: 40) was 7.88 years and the control group was 8.00 years. In the trauma group, 86 children were exposed to blunt trauma, 15 children had penetrating trauma and 54 patients had multiple trauma. Surgical procedures were performed on 17 patients. In the trauma group, native thiol, total thiol, dynamic disulphide/total thiol, albumin and IMA levels were significantly lower than that of the control (P < .001), and their dynamic disulphide (P = .001) was higher compared with the control. There was no difference thiol-disulphide parameters in trauma groups sub-division as surgery (n = 17) vs follow-up (n = 84) groups or multiple trauma (n = 54) vs isolated organ trauma (n = 47) groups or penetrating (n = 15) or blunt trauma (n = 86) groups. CONCLUSION: Thiol-disulphide balance and IMA levels show changes in favour of oxidative stress in children with trauma; however, it cannot be used as a laboratory marker that helps to show the system and organ affected by the trauma and to decide the surgical intervention.

RESUMO

Alternative technologies, which have been developed in order to meet the consumers' demand for nourishing and healthy meat and meat products, are followed by the food industry. In the present study, it was determined, using the HPLC method, that green tea contains a high level of epicatechin (EP) under optimal conditions and that pomegranate peel contains a high level of punicalagin (PN). Green tea, pomegranate peel, EP and PN were added to meatballs at different concentrations in eight groups. The antioxidant capacities of extracts were measured. The antimicrobial activity was examined for 72 h using three different food pathogens. The highest level of antimicrobial activity was achieved in the 1% punicalagin group, whereas the minimum inhibition concentration (L. monocytogenes, S. typhimurium) was found to be 1.87 mg/mL. A statistically significant decrease was found in FFA, POV and TBARS levels of meatballs on different days of storage (p < 0.05). When compared to the control group, the bioactive compounds preserved the microbiological and chemical properties of meatballs during storage at +4 °C (14 days). It was concluded that the extracts with high EP and PN concentrations can be used as bio-preservative agents for meat and meat products.

RESUMO

Up to date, only five cases of iatrogenic tracheal rupture during rigid bronchoscopy have been reported in children. Herein, we report the first case who has recovered with spontaneous respiration without intubation. Rigid bronchoscopy of a 19-month-old girl revealed a foreign body at the right main bronchus. While the bronchoscope was being withdrawn, we identified a 0.5-cm longitudinal mucosal laceration along the right wall of the membranous trachea. As her spontaneous respiration was adequate, she was treated conservatively. For the treatment of tracheal lacerations, while early surgical repair has traditionally been acceptable, evidence supporting conservative treatment is increasing, particularly in paediatric cases. If spontaneous respiration is sufficient, bridging the laceration with an endotracheal tube may not be required.

RESUMO

Electrical injuries comprise 4% of cases but have higher morbidity and mortality. This study aims to share our experiences with pediatric electrical injuries and propose strategies to prevent them. The files of pediatric electrical injuries between 2010 and 2020 were reviewed retrospectively. The following were investigated: age, gender, cause, length of stay in the pediatric burn center, total burned surface area, voltage-type, and surgical procedures performed. The patients from low- and high-voltage groups were compared. Eighty-five patients were treated in the last 10 years. Seventy were males, the mean age was 9.9 years, the average length of stay in pediatric burn center was 18.2 days, and the average total burned surface area was 11.7%. Forty-three patients were injured with high-voltage and 42 with low-voltage electricity. Fasciotomy was performed in 25 patients, grafting in 40 patients, and amputation in 12 patients. The most often amputated limb was the right arm/forearm. Psychiatric disorders developed in 24 patients. One patient died. In conclusion, the incidence of high-voltage electrical injuries increases with age. They are more prevalent in males, more often accompanied by additional trauma, and have higher total burned surface area, surgical procedures are performed more often, and hospitalization times are longer. For prevention, precautions should be taken by governments and families, and education is critical.

RESUMO

BACKGROUND/PURPOSE: During testicular torsion, the testes face oxidative damage owing to ischemia/reperfusion. We studied the long term effects of the intrascrotal administration of N-acetylcysteine (NAC) during detorsion procedure in a rat model of testicular torsion. METHODS: Twenty-eight rats were divided into 4 groups: (1) Control group: No procedure was done (2): Torsion-detorsion group: Testis torsion applied for 3 h (3): Low Dose Group: After testis torsion-detorsion (for 3 h) 10 mg/kg NAC was given into tunica vaginalis (4): High Dose Group: After testis torsion-detorsion (for 3 h) 100 mg/kg NAC was given into tunica vaginalis. We measured dimensions of the testes and examined pathological findings and Johnsen and Cosantino Scores. RESULTS: For testes height and volume, high dose NAC group had better results than the torsion-detorsion group (p = 0.019, p = 0.049). Testes weight showed no difference (p = 0.204). Sertoli cell number per tubule in the high dose NAC group was statistically different than the torsion-detorsion group (p = 0.017). CONCLUSIONS: When NAC was given intrascrotally at a dose of 100 mg/kg, it decreased the loss of testis volume and height, and Sertoli cell number per tubule was similar to the control group. These results suggest that the higher dose intrascrotal NAC administered during detorsion may have a protective effect.

RESUMO

For decades, water and oil repellency of engineering thermoplastics has been achieved with introduction of long-chain perfluoroalkyl substances and moieties (C nF2 n+1, n ≥ 7). However, their bioaccumulative and toxicological impact is now widely recognized and, consequently, the substances have been phased out of industrial production and applications. To this end, we have synthesized fluorinated oligomeric triblock polyesters (FOPBs), which do not possess the long-chain perfluoroalkyl segments and serve as effective low-surface-energy additives to engineering thermoplastics. More specifically, we obtained original perfluoropolyether (PFPE)-based triblock copolymers, in which two identical fluorinated blocks were separated by a short nonfluorinated polyester block made of poly(ethylene isophthalate) (PEI). It was found that when FOPBs were added to poly(ethylene terephthalate), nylon-6, and poly(methyl methacrylate) films they readily migrate to the film surface and in doing so imparted significant water and oil repellency to the thermoplastic boundary. The water/oil wettability of the films modified with FOPB is considerably lower than the wettability of the films modified with an analogous PFPE-based polyester, which differs from FOPB only by the absence of the short nonfluorinated PEI middle block. We associate the superiority of the triblock copolymers in terms of water and oil repellency with their ability to form brushlike structures on polymer film surfaces.

RESUMO

OBJECTIVE: To elucidate epidemiological data and hydrocele progression, we reviewed pediatric patients diagnosed with hydroceles in our institution retrospectively. MATERIALS AND METHODS: We reviewed data from 355 pediatric patients with hydroceles. Questionnaires regarding age at diagnosis, time of delivery, presence of hydroceles in the father and brothers, age at recovery, age at surgery, cause of hydrocele (if present), type of hydrocele, associated pathologies, treatments, and posthydrocelectomy complications were completed by reviewing patients' medical records and interviewing their families. RESULTS: Patients with congenital hydroceles were more frequently born prematurely (32.5%) than were patients with noncongenital hydroceles (15.9%; P = .001). Fathers of 10 patients (3.7%) and brothers of 21 patients (7.7%) also had hydroceles. Hydroceles were associated with inguinal hernias on the same side (12.2%), cryptorchidism (7.5%), varicoceles (6.0%), and testis torsion (0.5%). Among patients aged >1 year (n = 185), 27 did not undergo operations and healed spontaneously at an average of 5.30 ± 3.36 months. For children aged >1 year who did not undergo surgery, the rate of spontaneous recovery within 6 months was 77.8% and that within 1 year was 96.3%. CONCLUSION: Until strong evidence of hydrocele-induced testicular damage in children arises, we recommend following up congenital hydroceles until at least 1 year and preferably 2 years of age. We recommend following up noncongenital hydroceles for at least 6 months and preferably 1 year if there is no associated pathology indicating the need for earlier surgery such as an inguinal hernia, cryptorchidism, tense hydrocele, testis torsion, or testis mass.

RESUMO

Original perfluoropolyethers (PFPE)-based oligomeric polyesters (FOPs) of different macromolecular architecture were synthesized via polycondensation as low surface energy additives to engineering thermoplastics. The oligomers do not contain long-chain perfluoroalkyl segments, which are known to yield environmentally unsafe perfluoroalkyl carboxylic acids. To improve the compatibility of the materials with polyethylene terephthalate (PET) we introduced isophthalate segments into the polyesters and targeted the synthesis of lower molecular weight oligomeric macromolecules. The surface properties such as morphology, composition, and wettability of PET/FOP films fabricated from solution were investigated using atomic force microscopy, X-ray photoelectron spectroscopy, and contact angle measurements. It was demonstrated that FOPs, when added to PET film, readily migrate to the film surface and bring significant water and oil repellency to the thermoplastic boundary. We have established that the wettability of PET/FOP films depends on three main parameters: (i) end-groups of fluorinated polyesters, (ii) the concentration of fluorinated polyesters in the films, and (iii) equilibration via annealing. The most effective water/oil repellency FOP has two C4F9-PFPE-tails. The addition of this oligomeric polyester to PET allows (even at relatively low concentrations) reaching a level of oil repellency and surface energy comparable to that of polytetrafluorethylene (PTFE/Teflon). Therefore, the materials can be considered suitable replacements for additives containing long-chain perfluoroalkyl substances.
