RESUMO
INTRODUCTION: This study aims to review the primary spontaneous pneumothorax (PSP) patients we have treated and to discuss the results in terms of PSP treatment management and video-assisted thoracoscopic surgery (VATS) use in the light of the literature. METHODS: The study was designed retrospectively and conducted at a tertiary referral university hospital between January 1, 2015 and May 1, 2021. Patients under the age of 18 years with a diagnosis of pneumothorax (PTX) were included in the study. Medical records were analyzed in terms of clinical characteristics, demographic data, findings from imaging data, procedures performed, and course of the disease at hospital. Patients with no evidence of PTX on radiologic imaging (direct postero-anterior chest X-ray (PACXR) or thoracic computed tomography (TCT)), incomplete medical records for follow-up, history of trauma, and neonatal PTX were excluded from the study. RESULTS: The study was conducted on a total of 98 PTX cases in 69 patients, 61 (88.4%) males and eight (11.6%) females. The ages of the patients ranged between 13 and 17 years with a mean of 16.59 ± 0.95 years. While 48 (49%) PTX cases were treated with tube thoracostomy, 19 (19.4%) were treated with medical follow-up (nonsurgical treatment) and 31 (31.6%) were treated with VATS. A total of 31 VATS procedures were performed on 28 patients. The follow-up period after VATS ranged from tthree to 78 months, with a mean of 31.5 ± 20.3 months and a median of 28 months. CONCLUSION: Our retrospective study showed that TCT scanning did not provide additional benefit when PSP was detected on PACXR in patients presenting with chest pain and respiratory distress. According to the findings of our study, it was thought that the probability of undergoing an invasive procedure and surgical intervention increased as the percentage of PTX detected in PACXR increased. Tube thoracostomy may be required in a patient with PSP if PTX does not start to decrease and lung expansion does not increase after an average of 60 hours after the decision for medical follow-up, and if PTX is progressive in the follow-up. VATS can be performed on a patient with PSP when lung expansion does not increase after an average of 18 hours after tube thoracostomy, when PTX progresses, when air leakage continues for more than 10 days despite increased lung expansion, and when recurrent PTX occurs.
RESUMO
BACKGROUND: The present study aimed to investigate the changes in the course of acute appendicitis during the pandemic period by comparing the cases treated during the coronavirus disease 2019 (COVID-19) pandemic with those in the pre-pandemic period. METHODS: The study was conducted with 601 children aged 1-18 years who were operated for acute appendicitis between May 1, 2019, and February 29, 2020 (Group I) and between March 1 and December 31, 2020 (Group II). The demographic and disease characteristics as well as the treatment processes were compared between the groups. RESULTS: It was found that 59.1% (n=355) of the cases included in the study were in Group I and 40.9% (n=246) were in Group II. During the pandemic period; due to the concerns of families about contracting a contagious disease for both themselves and their children, and warnings by health professionals and government officials that they should not leave their homes and not come to the hospital unless there is an emergency, the time to apply to the hospital has been extended. Before the pandemic, 20.3% of the patients presented to the hospital on the 1st day of their complaints, where during the pandemic, only 2% of the patients reported to the hospital on the 1st day, and 15% presented after 4 days or more. As a result, the rate of perforated appendicitis, which was formerly 10.4%, increased to 24.8% during the pandemic period (p<0.01). During the pandemic, we operated on four patients with positive COVID-19 test results. There were no complications related to COVID-19 and surgery in our patients. CONCLUSION: Concern of the current pandemic resulted in late presentation to the hospital, increase in the number of perforated appendicitis, and prolonged hospital stay.

INTRODUCTION: Prolonged inflammation after tracheal injury invariably results in a degree of stenosis. The topical application of platelet-rich plasma (PRP) and human amniotic fluid-derived cell culture medium (ACCM) have been shown to promote wound healing. The effects of PRP and amniotic cell culture medium (Gibco AmnioMAX - II ) were investigated in a rat model through morphometric, histological, and biochemical parameters. MATERIAL METHODS: Thirty-two male Sprague Dawley rats were included in the study: 4 rats provided for the preparation of PRP. Three groups of 7 rats were divided into PRP and ACCM groups, a control and a sham group respectively. A transverse incision on the ventral aspect of the third trachea spanning half of the tracheal circumference was performed. The incision was repaired with 7/0 polypropylene in the sham group. In the control group, 0.5 ml saline solution was applied on to the repaired injury site. In the other two groups, 0.5 mL PRP or ACCM were applied topically on the tracheal repair. Tissue samples were harvested 30 days after surgery for morphometric measurements and biochemical analyses for oxidative stress markers, IL-1beta, IL-6, and VEGF. Connective tissue thickness was evaluated histologically. Statistical analysis included the Mann-Whitney U and Kruskal Wallis tests. RESULTS: A notable difference was detected (Pâ=â0,025) in cartilage segment length measurements of the trachea between the ACCM group and the sham and control groups (P < 0.03). A significant difference was found in the analysis of TAS, TOS, and OSI values between the study groups and the control and sham groups (Pâ<â0.005). There were also differences in IL1-beta and IL-6 levels between ACCM and PRP groups (P < 0.05). For the same parameters, the differences were significant between the PRP and, sham and control groups (Pâ=â0,004 and P = 0,002 respectively), and between the ACCM and, sham and control groups (P = 0,003 and P = 0,002 respectively).VEGF values demonstrated a significant difference between the PRP and sham group (Pâ=â0,002), and between ACCM and sham/control groups (p=0,002 for both), the highest VEGF value was in ACCM group while the lowest value was in the sham group. In the histological assessment of connective tissue, a significant difference was observed between ACCM and the other groups. CONCLUSION: Amniotic fluid-derived cell culture medium shows less oxidative stress status than the other applications. ACCM is more effective on inflammatory and angiogenetic processes. Connective tissue thickness results were consistent with those biochemical and morphologic results. Additionally, a significant difference was observed in histological data between ACCM and PRP. Overall, ACCM proved to be efficient on tracheal healing. These effects can be attributed to the abundance of growth factors in both PRP and amniotic fluid-derived cell culture medium (ACCM).

OBJECTIVE: The surgical flap delaying has been shown to be effective in preventing partial flap loss or in preparing larger flaps. However, there is no gold standard flap delay method in the literature. In this study, the authors aimed to compare 3 types of surgical delay methods to determine which model would increase more flap survival. The authors also investigated the effect of delay methods on circulating mononuclear leukocytes as a parameter of DNA damage. METHODS: Twenty-four Sprague-Dawley male rats were divided into 4 groups. All subjects had a 10 × 3âcm modified McFarlane flap. Surface area measurements, biopsies, and blood samples were taken on the day of sacrification; 7th day for the control group and 14th day for delay groups. RESULTS: Between incisional surgery delay groups, a significant difference was found in necrosis and apoptosis in the bipedicled group, and only necrosis in the tripedicled group compared to the control. In terms of DNA damage, it was found higher in all experimental groups than in the control group. CONCLUSIONS: Both incisional surgical delay procedures' results were meaningfully effective when only incisions were made without the elevation of flaps. In conclusion, bipedicled incisional surgical delay seems to be the most effective method in McFarlane experimental flap model whereas two-staged surgeries may increase the risk of systemic toxicity.

Familial Mediterranean fever (FMF) is a recurrent disease with autosomal recessive trait and fever that is generally self-limiting. Clinical manifestations are pain in the abdomen, chest, and joints as a result of inflammation in the serous surfaces. No case of multiple intestinal perforations has been reported in children with FMF, whereas cases with a single intestinal perforation have been encountered, although very rarely. In addition, co-occurrence of FMF and inflammatory bowel disease is a situation that is very rarely reported in the literature. Here, we report a case of a 5-year-old girl who was being followed up with the diagnosis of FMF and who also had inflammatory bowel disease, which was complicated with multiple ileal perforations. Our aim is to point out a rarely encountered co-occurrence and also the importance of evaluation of additional diseases with FMF that are unresponsive to treatment so as to prevent complications.

OBJECTIVE: We investigate the protective and therapeutic effects of ozone therapy (OT) in radiotherapy (RT)-induced testicular damage. METHODS: Thirty healthy adult male Wistar rats divided into five groups consisting of six animals each as follows: (1) Control (C), (2) RT, (3) OT, (4) OT + RT, and (5) RT + OT group. Histopathological findings, Johnsen scores, thiobarbituric acid-reactive substances (TBARS), glutathione (GSH), superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPx) levels were evaluated. RESULTS: RT caused a significant decrease in testicular weight and Johnsen score compared to the control group. In addition, TBARS level was significantly higher, whereas GSH, SOD, catalase, and GPx levels were significantly lower in the RT group when compared to the control group. Pre and postRT OT significantly increased GSH, SOD, catalase, and GPx levels and decreased TBARS level. Furthermore, testicular weight and Johnsen score were increased with OT. CONCLUSIONS: The present study showed that OT is protective and therapeutic in radiation-induced testicular damage. OT may be beneficial to the patients who underwent RT.

OBJECTIVES: For perforated appendicitis in children, microbiological cultures should always be sought if an adequate sample is available. Knowledge of local epidemiology is important for optimal selection of antimicrobial therapy. The aim of this study was to evaluate the aetiology and susceptibility of pathogens in paediatric patients with perforated appendicitis. METHODS: Microbiological results of tissue samples obtained at surgery from children with acute appendicitis over 24 months were evaluated retrospectively. RESULTS: Among 209 children operated for acute appendicitis, 62 (29.7%) were perforated appendicitis. Intraperitoneal culture results were available for 42 patients, of which 41 (97.6%) had positive microbiological growth (57 pathogens). The male:female ratio was 1.8 and the mean age at presentation was 11 years (range 4-18 years). The most common pathogen was Escherichia coli (66.7%), among which 57.9% produced an extended-spectrum ß-lactamase (ESBL). All patients received initial treatment with intravenous antibiotics (ampicillin, gentamicin and metronidazole). The antibiotic regimen was modified in 22 patients (52.4%). Seven patients (16.7%) developed a post-operative complication. No significant difference was observed for development of complications between patients with ESBL-positive and -negative E. coli growth (P=0.698). CONCLUSION: The high rate of ESBL-positive E. coli may indicate bowel colonisation with resistant bacteria even in the community setting. Prospective studies will show whether treatment options should be directed according to identified pathogens.

Purpose/Aim: Acute mesenteric ischemia is a syndrome characterized by sudden onset abdominal pain followed by intestinal necrosis. Morbidity and mortality increase with delayed diagnosis. Even with the latest radiological diagnostic methods, early diagnosis and initiation of treatment can be delayed. Using an experimental model, here we aim to determine the relationship between the laboratory parameters used to detect acute mesenteric ischemia and the duration of irreversible ischemia. Materials and Methods: A total of 30 male Wistar albino rats were divided into five groups, all of which underwent general anesthesia: (i) Superior mesenteric artery (SMA) dissection with laparotomy was performed, and blood samples and intestinal segment samples were taken after 2 hr (Sham group); (ii) volvulus of one-third of the small intestines was performed manually by laparotomy, and blood samples and intestinal segment samples were taken after 2 hr (Volvulus group); (iii) SMA was ligated with laparotomy, and blood samples and intestinal segment samples were taken after 2 hr (SMA+ligated 2-hr group); (iv) SMA was ligated with laparotomy, and blood samples and intestinal segment samples were taken after 4 hr (SMA+ligated 4-hr group); and (v) SMA was ligated with laparotomy, and blood samples and intestinal segment samples were taken after 6 hr (SMA+ligated 6-hr group). Results: The mean lactate dehydrogenase (LDH) activities of the SMA+ligated 2-hr and SMA+ligated 6-hr groups were statistically higher than the control group (p = .004). Compared to the Sham and Volvulus groups, the mean lactate level of the SMA+ligated 6-hr group was significantly higher (p = .004). Compared to the Sham and Volvulus groups, the mean D-dimer levels of the SMA+ligated 4-hr and SMA+ligated 6-hr groups were significantly higher (p = .004 and .003, respectively). By histopathological evaluation, we found that pathological damage increased as the ischemia lengthened. Conclusions: Mesenteric ischemia leads to an irreversible loss of intestinal perfusion and an increase in parameters of ischemia. Irreversible tissue damage occurs after 4 hr of ischemia and peaks after 6 hr, whereas parameters of ischemia (D-dimer, LDH, and L-Lactate levels) are highest at 2 hr after the onset of ischemia.

Neurenteric cyst is a very rare developmental anomaly. Prenatal diagnosis of mediastinal neurenteric cysts has been reported rarely. We present a case of neurenteric cyst associated with vertebral anomalies diagnosed by prenatal ultrasonography at 31 weeks of gestation, which was treated successfully in the early neonatal period. In addition, we searched the English literature for all cases of mediastinal neurenteric cyst diagnosed in the prenatal period reported to date. We found that only 17 cases were reported previously. We reviewed the reports of these 17 patients along with our case, and we investigated the prenatal and postnatal diagnosis and treatment approaches and the factors influencing the prognosis. Fetuses with mediastinal neurenteric cysts should be monitored regularly by ultrasonography. Fetuses with no signs of hydrops are more likely to survive with proper neonatal center transfer, regular follow-up, and appropriate postnatal approach. Fetuses with hydrops findings have a high risk of fetal and neonatal death.

PURPOSE: Laparoscopy is widely used in many surgical areas for diagnosis and treatment. The need for sterilization of reusable instruments is an important issue. Ensuring patient safety, preventing infection, and protecting the functionality of the instruments are the most important points to be considered. We aimed to investigate two sterilization methods and their effects generated by their distribution into intra-abdominal tissues during insufflation. MATERIALS AND METHODS: 21 rats were used in the study. The Control Group (Group 1) received anesthesia for 1 hour; Group 2 (Glutaraldehyde (GA)-Pneumoperitoneum Group) received anesthesia for 1 hour; Group 3 (Ethylene Oxide (EO)-Pneumoperitoneum Group) received anesthesia for 1 hour. After 24 hours, the animals were sacrificed, and the kidneys and omentum of the animals were analyzed in a histopathological manner. Blood samples were analyzed at preoperative 24th hour and at postoperative 24th hour. RESULTS: There was a statistically significant difference in omentum, endothelium, and glomerular scores between the groups (p < 0.001 for all groups). Endothelial and glomerular scores were different at a statistically significant level in the EO and GA groups compared to the Control Group. The total score was higher at a statistically significant level in the EO and GA groups compared to the Control Group (p < 0.001 for both groups). CONCLUSION: It was determined in our study that sterilization methods such as EO and GA cause damage in intra-abdominal tissues. In the light of these results, we consider that the most ideal laparoscopic surgery set is the single-use laparoscopy set. However, this does not seem possible especially in developing countries in practice.

INTRODUCTION: Pneumoperitoneum (PP) is known to cause ischemia in kidneys and other intra-abdominal organs because of decreased splanchnic blood flow. AIM: We aimed to determine the degree of renal injury that occurs due to a PP and prolonged PP. We measured renal injury biomarkers and made a histopathological evaluation to estimate the degree of injury and assessed the correlation of biomarkers with histopathological findings. MATERIAL AND METHODS: Twenty-one female Sprague Dawley rats were separated randomly into three groups. Group 1 was the control group and was given anesthesia for 3 h. In group 2, a PP was administered under anesthesia for 1 h. A pneumoperitoneum was administered under anesthesia to animals in group 3 for 3 h. RESULTS: Pathological analysis showed a significant statistical difference between the 3 groups. In particular, neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C (Cys C) levels at the 24th h and preoperative mean urea levels showed a significant difference between the groups. The 24th-hour NGAL level in group 3 was significantly higher than that of group 1. The preoperative Cys C level was higher in group 1 than in either group 2 or 3. Cys C was decreased significantly in group 1 and increased significantly in both groups 2 and 3. CONCLUSIONS: The increase in NGAL and Cys C levels directly correlated with the duration of PP and intra-abdominal pressure, and they are therefore good biomarkers in diagnosing acute renal injury in the early phase. Serum creatinine level is not a good biomarker in the early phase of renal injury.
RESUMO
Solid pseudopapillary tumor (SPT) of the pancreas is a pathological entity rarely encountered in children. Despite its malignant characteristics, SPT has a favorable clinical prognosis. This tumor is more frequently observed in females and is commonly localized in the tail and body of the pancreas. This is the case report of a 9-year-old female patient who presented with severe abdominal pain of sudden onset and vomiting following blunt abdominal trauma. Upon physical examination, abdominal distension, tenderness and abdominal guarding were detected. Abdominal magnetic resonance imaging revealed a mass sized 8×9×12 cm in the pancreas, with hemorrhagic-necrotic areas, and abundant intra-abdominal fluid. Intra-abdominal exploration confirmed the presence of an abundant amount of intraperitoneal hemorrhagic fluid. A mass was identified, originating from the body and the tail of the pancreas, adherent to the mesentery of the colon and the hilum of the spleen, which had ruptured in its inferolateral side. The tumor was extirpated together with the spleen and the involved parts of the pancreas. Histopathological examination demonstrated a solid pseudopapillary tumor of pancreatic origin. The patient's postoperative course was uneventful, clinically as well as metabolically.
RESUMO
In the literature, there is no reported pediatric leiomyosarcoma case that has metastasized from the small intestine to the adrenal gland. A 10-year-old boy who had anemia and weight loss over 2 years presented with abdominal pain that began 1 week previously. Radiologic examination revealed bilateral adrenal tumors. At the time of surgery, the terminal ileum was resected and a tru-cut biopsy was done from the right adrenal mass. The pathology report was leiomyosarcoma for both of the resection and tru-cut specimens. We present an intestinal leiomyosarcoma that metastasized from the small intestine to both adrenal glands with clinical, morphologic, and immunohistochemical studies with a literature review.
