Can serum soluble urokinase plasminogen activator receptor be an effective biomarker in comparing the inflammatory response between laparoscopic and open appendectomy?

Introduction: The inflammatory response after laparoscopy and laparotomy has been compared in studies in adults, but only a few studies have compared the immune response between laparoscopy and laparotomy in children. Aim: To compare open and laparoscopic appendectomies regarding a new biomarker, suPAR, to evaluate the inflammatory response. Material and methods: Patients between 3 and 17 years of age who were admitted to the pediatric surgery department and scheduled for appendectomy due to appendicitis were enrolled in the investigation. The patients were randomized to receive either laparoscopic (n = 20) or conventional open appendectomy (n = 20). The primary outcome was a change in preoperative and postoperative suPAR levels. The secondary outcomes were the white blood cell count, lymphocytes, neutrophils, platelets, C-reactive protein level, appendix diameter, symptoms, symptom duration, surgical complications, operative time, rescue analgesics, hospital stay, and family satisfaction. Results: The mean age of the patients undergoing laparoscopic appendectomy was 10.55 ±2.743 (3-17) years. The mean age of the patients undergoing open appendectomy was 11.40 ±3.515 (3-17) years. A statistically significant difference was found when the postoperative suPAR values between the two groups were compared (p = 0.048). The operative time and hospital stay in the laparoscopic group were significantly shorter than those in the open group (p = 0.001, p = 0.047). Conclusions: Laparoscopic appendectomy is associated with a shorter operative time, a shorter hospital stay, and a smaller inflammatory response caused by surgical stress than open appendectomy. suPAR is an effective marker for comparing postoperative inflammatory stress between open and closed appendectomies.

Long-term 10-year comparison of girls with congenital adrenal hyperplasia who underwent early and late feminizing genitoplasty.

OBJECTIVES: The appropriate time to perform feminizing genitoplasty in patients with congenital adrenal hyperplasia (CAH) with the 46, XX genotype is still debatable. The aim of our study was to evaluate the relationship between age at surgery and long-term surgical outcomes of patients who underwent feminizing genitoplasty. METHODS: We retrospectively analyzed 14 patients with CAH and 46, XX genotypes with feminizing genitoplasty (clitoroplasty + vaginoplasty) between 2005 and 2022. The patients were divided into two groups. Group 1 consisted of seven girls (n = 7/14) who have been operated before the age of 2 years. Group 2 consisted of seven girls (n = 7/14) who have been operated after the age of 2 years. The two groups are compared regarding anatomical assessments, overall cosmetic results, need for additional intervention using Creighton's criteria. Additionally, the cosmetical satisfaction of the patients/parents is questioned. RESULTS: The mean age of the girls was 32.42 months (10-96 months) during operation time. The mean age of Group 1 patients (n = 7/14) who have been operated before the age of 2 years was 11.71 months (10-19 months). The mean age of Group 2 patients (n = 7/14) who have been operated after the age of 2 years was 53.14 months (36-96 months). The mean follow-up time was 10.57 years (3-18 years). There was no statistically significant difference between those operated on before and after two years in terms of anatomical assessments, overall cosmetic results and patient/parent satisfaction except the need for additional intervention (p = 0.049). In Group1 (operation age < 2 years old), five out of seven (71.42%) patients needed additional major surgery (four urogenital sinus re-mobilization, one redo-clitoroplasty). Those who received additional major surgery were the ones who were not satisfied. In Group 2 (operation age > 2 years old), two patients out of seven patients (28.57%) received major surgery (two redo-urethroplasties) and those patients were not satisfied. When patient/parent satisfaction was compared with additional surgical intervention, as expected, patients'/parents' satisfaction increased as major surgical intervention decreased. This was statistically significant (p = 0.007). The main source of dissatisfaction was repeated surgery among the parents. CONCLUSIONS: The possibility of this additional surgical intervention increases, and patient/parent satisfaction decreases in patients below the age of 2 years. The corrective surgeries can be differed until the gender identity of the patient matures and the patient autonomy in deciding whether this surgery should occur.

Endoscopic pilonidal sinus treatment (EPSIT) versus sinus laser therapy (SiLaT) for sacrococcygeal pilonidal sinus.

Introduction: New surgical treatment methods are being investigated in sacrococcygeal pilonidal sinus disease. Minimal invasive methods such as endoscopic pilonidal sinus treatment (EPSIT) and sinus laser therapy (SiLaT) have promising results and advantages of laparoscopic surgery. Aim: To compare the efficiency and safety of EPSIT with SiLaT. Material and methods: Seventy-three patients with pilonidal sinus who had undergone EPSIT or SiLaT within 2 years were evaluated retrospectively. Data of patients' demographics, complications and postoperative course were collected and compared between the two groups. Results: We analyzed seventy-three patients who underwent EPSIT or SiLaT, with a mean age of 23.4 ±8.4 (12-46) years and body mass index (BMI) of 25.5 ±4.5 (18-38) kg/m2. Among them, 36 patients (26 males, ten females) underwent EPSIT and 37 patients (27 males, ten females) underwent SiLaT. Mean operative time was similar for both groups (32.3 ±14.8 vs. 31.0 ±14.8; p = 0.757). Early complications (minimal bleeding) were recorded in 2 patients in the SiLaT group. The duration of analgesic use was significantly lower in the EPSIT group compared to the SiLaT group (1.3 ±0.5 (1-3) vs. 1.9 ±1.1 (1-5); p = 0.005). The mean postoperative time of total wound healing was similar for both groups: 23.6 ±14.7 (12-90) vs. 25.2 ±14.5 (14-90) days (p = 0.385). There was no significant difference in the average time of return to total daily activity (3.4 ±0.9 (2-5) vs. 3.6 ±1.2 (2-7) days, p = 0.679). There were no significant differences between the groups regarding late postoperative complications (recurrence: 7). Conclusions: Both methods have similar early and late complications. The duration of need for analgesic usage was shorter in EPSIT patients.

Ovarian and paraovarian adrenal rest tumors are not uncommon in gonadectomy materials of historical congenital adrenal hyperplasia cases in childhood.

Objective: The aim of this study was to assess the prevalence of ovarian and paraovarian adrenal rest tumors (ARTs) in gonadectomy materials of a subgroup of congenital adrenal hyperplasia (CAH) patients. Methods: A total of 20 historical cases with clinical/molecular diagnosis of classical CAH were included in the study. All patients had 46,XX karyotype and underwent gonadectomy because of being raised as male. Results: Median age at diagnosis of CAH was 5.7 years and was markedly delayed. All patients revealed severe virilization. Bone age was significantly advanced, and bone age/chronological age ratio was increased with a median ratio of 1.8. Median age at the time of gonadectomy was 9.2 years. Ovarian and paraovarian ARTs were detected during the pathological evaluation of gonadectomy materials in four patients (20%) (two with simple virilizing 21-hydroxylase and two with 11-beta-hydroxylase deficiency) with previously normal pelvic imaging. In three cases with ARTs, paraovarian area was composed of medium-sized polygonal cells, with round or oval monomorphic nuclei and abundant granular eosinophilic cytoplasm which is characteristic of adrenocortical tissue. The fourth case had bilateral ovarian 'steroid cell tumors, not otherwise specified', and the tumor was accepted as benign. Except for the ARTs, heterotopic prostate and bilateral paratubal epididymis tissue were detected in a patient. Conclusions: Ovarian and paraovarian ARTs might be more common than previously described, especially among patients with excessive and prolonged adrenocorticotropic hormone exposure. These tumors could be detected histopathologically even if not detected by classical imaging methods.

The Use of Social Network in Daily Pediatric Practice and Education: Turkish Pediatric Atelier.

Using social media applications in pediatric education is not outdated, and its effectiveness has not been tested yet. For this reason, we shared the first results of the Pediatric Atelier experience that we realized through telegram application. We make an online survey to investigate the needs, requirements, pleasure, and suggestions of members through a web-based questionnaire. This cross-sectional survey study was delivered only to participants who were members of the workshop via their email addresses. Online questionnaires organized using Google Forms were sent to pediatric workshop members between March and June 2019. The questionnaire consisted of questions that measured the participants' basic demographic data, the use of the workshop, and the overall impact of the workshop on their professional behavior. While the institutions and positions of the participants were recorded, no other personal data (such as address and telephone) were collected. Among the 997 members, 417 (42%) of them answered the questionnaire. Respondents included 300 (72%) pediatrician, 21 (5%) pediatric subspeciality fellows, and 75 (18%) pediatric subspecialists. Of the 417 respondents, 217 (52%) were working in Istanbul, and 200 (48%) were working in other cities of Turkey. Among the responders, 233 (56%) were working in private hospitals or doctor offices. A total of 520 cases were consulted in 241 days of study period. Most consultations (n = 309, %59) were made from the Istanbul metropolitan area, and 203 (40%) consultations were from other cities of Turkey. The most frequently consulted departments were Pediatric infectious diseases: 166 (32%), Pediatric hematology and oncology: 56 (11%), and Neonatology: 43 (8%). Of the 520 consulted cases, 44 (8%) were related to life-threatening events, and 25 of them were hospitalized in the intensive care units, and 6 of them were required surgical operations. Of the 94% of responders thought this platform was useful and 82% of them stated that the case counseling part of the atelier was the most useful part. We think that the development of technology and artificial intelligence may lead to the usage of on-line platforms or systems in clinical medical practice. Clinical Trial Registration (if any).

Long-term outcomes of six patients after partial internal biliary diversion for progressive familial intrahepatic cholestasis.

BACKGROUND: Partial internal biliary diversion (PIBD) is an alternative approach for the treatment of devastating pruritus in patients with progressive familial intrahepatic cholestasis (PFIC). In these patients quality of life can be improved and progression of liver disease can be delayed while waiting for liver transplantation. The aim of our study was to evaluate six patients with PFIC who have undergone PIBD in long-term follow-up. METHODS: Retrospective review of the records of six patients who underwent PIBD for PFIC between 2008 and 2010 was conducted to evaluate age, growth, clinical and laboratory studies for long-term outcome. RESULTS: Serum postoperative bile acid levels were reduced from a mean 340.1µmol/L (range 851-105) preoperatively to a mean of 96.3µmol/L at postoperative fifth year. The difference between pre- and postoperative bile acid levels was statistically significant (p=0.018). AST decreased from 79.1U/L (range 43-150U/L) to 64.6U/L (range 18-172U/L), ALT decreased from 102.8U/L (range 35-270U/L) to 84.6U/L and total bilirubin decreased from 2.9µmol/L (range 0.35-6.4µmol/L) to 1.53µmol/L (range 0.3-2.4). Again, the decrease in total bilirubin levels was significant (p=0.043). Pruritus was diminished from a mean of +4 (range 4-4) preoperatively to a mean of +2 (4-0). One patient who underwent liver transplantation owing to relapsing pruritus died from postoperative sepsis in the early postoperative period at the fifth year after PBID. Five symptom-free patients have not required liver transplantation at a mean period of 6.1±0.83years (5.1-7.0years) follow-up. CONCLUSION: PBID is an effective surgical procedure in the long-term and can delay the need for liver transplantation in children with PFIC by reducing jaundice and pruritus.

Is there a determining factor that predicts mortality in patients with congenital diaphragmatic hernia?

AIM: This study was designed to investigate the factors affecting the prognosis in neonates with congenital diaphragmatic hernia (CDH) who were treated in our clinic. These factors included prenatal lung-head ratio (LHR), prenatal stomach and liver presence in the thorax, blood gases in the first 24 h and the modified ventilation index (MVI). MATERIAL AND METHODS: The study was carried out retrospectively in 30 neonates with prenatally diagnosed left CDH who were treated in our clinic between January 2007 and 2013. Data were collected, evaluated, and statistically analyzed for gender, birth weight, gestational age, prenatal LHR, prenatal presence of stomach and liver in the thorax, postnatal initial blood gases in the first 24 h and MVI. RESULTS: The median LHR for non-survivors was 1.49 and for survivors 1.51. No statistically significant difference in LHR was detected between survivors and non-survivors. In 19 neonates, prenatal ultrasonography (USG) revealed intrathoracic stomach, and 9 of these infants died. Intrathoracic liver was seen in 15 neonates, and 9 of these died. A statistically significant difference was not found between survivors and non-survivors in the intrathoracic liver or intrathoracic stomach neonates. A comparison between the non-survivors and survivors showed a median pH value of 7.10 in non-survivors and 7.24 in survivors (p = 0.002). The median PaCO2 value was 69.4 mm Hg in non-survivors and 51.9 mm Hg in survivors (p = 0.01). There were statistically significant differences in pH and PaCO2 values. The median value of MVI was 33 in survivors and 100 in non-survivors. There was a statistically significant difference between overall non-survivors and survivors in the MVI value (p < 0.05). CONCLUSIONS: Based on the findings, postnatal pH, and PaCO2 and MVI values are favorable prognostic factors in CDH in our selected group of patients.

Neonatal perforated appendicitis in incarcerated inguinal hernia in the differential diagnosis of testis torsion.

Appendicitis in newborns is uncommon and difficult to diagnose. Reports on neonatal appendicitis subsequent to inguinal hernia incarceration are exceptionally rare. We present the case of a 26-day-old infant with perforated appendicitis due to incarceration of a right inguinal hernia, mimicking right testicular torsion.

Enteric Duplication Cysts in Children: A Single-Institution Series with Forty Patients in Twenty-Six Years.

PURPOSE: The purpose of the study was to evaluate our experience with enteric duplication cysts in 40 children during the past 26 years, while assessing the variability of their presentations and to propose an algorithm for surgical management. METHODS: We retrospectively analysed sex, age, clinical presentations, duplication site, surgical treatment, presence of ectopic tissue, complications, associated anomalies, and prognosis of 40 patients with gastrointestinal tract duplications who were surgically treated in our clinic. RESULTS: Overall, there was a predominance of boys (28 males, 70 %; 12 females, 30 %). The presenting symptom was vomiting in 23 patients, rectal bleeding in 11 patients, abdominal mass in 10 patients, abdominal pain in 9 patients, constipation in 6 patients, cough in 2 patients, and respiratory distress in 2 patients. In 30 patients, a complete excision of the cyst with additional segmental intestinal resection and anastomosis was performed. Cystectomy was performed in seven patients, while complete excision of the cyst with additional wedge resection was performed in two. A Wrenn procedure (mucosectomy) was performed in one patient. CONCLUSION: Due to the variability in the site of enteric duplications, a wide range of presenting symptoms can exist, which is challenging for diagnosis. In children with a diagnosis of acute abdomen, enteric duplication cysts should be considered, and these children should be further investigated for additional skeletal, urogenital, and gastrointestinal system pathologies. Surgical treatment depends on the site and type of the cyst.

Small Bowel Obstruction due to Anomalous Congenital Bands in Children.

Introduction. The aim of the study was to evaluate our children who are operated on for anomalous congenital band while increasing the awareness of this rare reason of intestinal obstruction in children which causes a diagnostic challenge. Patients and Methods. We retrospectively reviewed the records of fourteen children treated surgically for intestinal obstructions caused by anomalous congenital bands. Results. The bands were located between the following regions: the ascending colon and the mesentery of the terminal ileum in 4 patients, the jejunum and mesentery of the terminal ileum in 3 patients, the ileum and mesentery of the terminal ileum in 2 patients, the ligament of Treitz and mesentery of the jejunum in one patient, the ligament of Treitz and mesentery of the terminal ileum in one patient, duodenum and duodenum in one patient, the ileum and mesentery of the ileum in one patient, the jejunum and mesentery of the jejunum in one patient, and Meckel's diverticulum and its ileal mesentery in one patient. Band excision was adequate in all of the patients except the two who received resection anastomosis for intestinal necrosis. Conclusion. Although congenital anomalous bands are rare, they should be considered in the differential diagnosis of patients with an intestinal obstruction.

The Role of Ozone Therapy in Hepatic Fibrosis due to Biliary Tract Obstruction.

PURPOSES: In this experimental study, we investigated the role of ozone therapy in hepatic fibrosis caused by biliary obstruction. MATERIALS AND METHODS: In this study, 21 male Sprague-Dawley rats were divided equally into three groups. In the control group, only laparotomy was performed and intraperitoneal cavity is washed with 1 mL of saline. In the sham group (SG), common bile duct is binded with laparotomy and no treatment is given afterward. In the experimental group (EG) after the binding of common bile duct with laparotomy, 1 mg/kg dose and 50 mg/mL concentration of ozone were applied rectally for 21 days. Hepatic tissue sample and intracardiac blood samples were collected from all animals at postoperative 21st day with relaparatomy. RESULTS: When we compared the experiment to SG, we detected a decrease in aspartate aminotransferase, alkaline phosphate (ALP), total bilirubin, and direct bilirubin levels in the EG, however, only the decrease in total bilirubin levels were statistically significant (p = 0.025). Histopathological examination of livers of rats in the EG showed lower level of hepatic fibrosis and inflammation. In the SG, incomplete cirrhosis was detected in 57.1% of the rats, whereas in the EG, no cirrhosis was detected. Immunohistochemically, periportal inflammation was 100% in the SG, whereas it was seen (3/7) 42.9% in the EG. A significant decrease in positive α-smooth muscle actin reaction was observed in ozone-treated group compared with SG. CONCLUSION: We suggest that ozone can decrease the hepatic destruction levels in experimental model of biliary obstruction.
