Impact of Scoliosis Severity on Gastrostomy-Related Complications in Children.

OBJECTIVES: This study aimed to determine the relationship between scoliosis and risk of developing complications in patients who underwent gastrostomy. METHODS: Patients who underwent percutaneous endoscopic gastrostomy (PEG) or surgical gastrostomy (SG) between 2012 and 2022 were included. Leakage, discharge, granuloma, and hyperemia were considered minor complications, while visceral injury, ileus, and re-do surgery were considered major complications. The degree of scoliosis was calculated using the Cobb angle. The SG and PEG groups were compared by evaluating the complications and their correlation with scoliosis. RESULTS: A total of 104 patients with a mean age of 5.0 ± 5.3 were included; 58% of patients were treated with SG. Patients in the SG group were younger ( P < 0.001). Minor complications were significantly more common in the PEG group ( P = 0.018). There was no difference between the groups in terms of major complications ( P = 1.000). Scoliosis was observed in 32.7% of the patients (n = 34). In the SG group, no correlation was found between the Cobb angle and the frequency of minor ( P = 0.173) or major complications ( P = 0.305). There was no significant difference between the Cobb angles of patients with and without minor complications in the PEG group ( P = 0.478); the Cobb angles of patients with major complications (75°) were significantly higher than those without (36°) ( P = 0.030). CONCLUSION: Gastrostomy is important for weight gain and nutritional needs of children. This study showed that the risk of complications in SGs did not correlate with the degree of scoliosis and that the risk of major complications in PEGs increased in patients with a high degree of scoliosis.

Differentiating abdominal pain due to COVID-19 associated multisystem inflammatory syndrome from children with acute appendicitis: a score system.

PURPOSE: Differentiating abdominal pain due to coronavirus disease (COVID-19)-associated multisystem inflammatory syndrome (MIS-C) in children with acute appendicitis (AA) can cause diagnostic dilemmas. This study aimed to evaluate the efficacy of a previously described scoring system and improve its diagnostic ability in differentiating between these diseases. METHODS: This study was conducted between March 2020 and January 2022. Patients who had MIS-C with gastrointestinal system (GIS) involvement and patients who underwent surgery for appendicitis were included. First, all patients were evaluated using the new scoring system (NSS). The groups were compared by adding new MISC-specific parameters to NSS. The scoring system was evaluated using propensity score matching (PSM). RESULTS: A total of 35 patients with abdominal pain due to GIS involvement in MIS-C (group A) and 37 patients with AA who had ALT, PRC, and D-dimer results at their first admission (group B) were included in the study. The mean age of patients in group A was lower than that of patients in group B (p < 0.001). False NSS positivity was found in 45.7% of the patients with MIS-C. Lymphocyte (p = 0.021) and platelet counts (p = 0.036) were significantly lower in the blood count and serum D-dimer (p = 0.034), C-reactive protein (CRP) (p < 0.001), and procalcitonin (p < 0.001) were significantly higher in the MIS-C group. We created a scoring system called the Appendicitis-MISC Score (AMS) using the NSS and new parameters. The sensitivity and specificity of AMS diagnostic scores were 91.9% and 80%, respectively. CONCLUSION: MIS-C with GIS involvement may present as acute abdomen. It is difficult to differentiate this condition from acute appendicitis. AMS has been shown to be useful for this differentiation.

Rectal biopsy: is it really necessary in anorectal malformations?

AIM OF THE STUDY: The coexistence of Hirschsprung's disease (HD) with anorectal malformation (ARM) is rare but many surgeons still ask pathologists to look for ganglia in the terminal rectum or fistula. In this study, we aimed to highlight the rarity of this association and question the necessity of histological evaluation. METHODS: After obtaining board review approval, rectal specimens of ARM patients who underwent corrective surgery in the last 8 years were re-analyzed by two blinded pathologists for the presence and structure of ganglia. Clinical and radiological data of patients retrieved from center records and correlated with histopathologic findings. MAIN RESULTS: 67 patients with ARM were identified, distal rectal specimen was obtained in 47. The median age at the time of surgery was 11 months (2 days-59 months). A normal pattern of ganglia was present in 51.1% (24/47), 29.7% (14/47) had aganglionosis and 19.1% (9/47) were inconclusive due to insufficient material. None of the aganglionic specimens showed other histological findings of HD. Patients were followed up regularly in the outpatient colorectal clinic for a median of 87 months (42-117 m). Only 6 experienced severe constipation (3 ganglionic, 2 no biopsy, 1 aganglionic), all of whom responded to a bowel management program, and none developed other manifestations of HD (abdominal distension, failure to thrive or enterocolitis) or required additional surgery. CONCLUSIONS: Our results strongly suggest that the association of ARM and HD is extremely rare and the practice of searching for ganglia in the distal rectum or fistula of ARM patients should be discouraged to avoid potential misdiagnosis and overtreatment.

Reassessment of a Decade of Experience on Testicular Torsion: Are We Making a Mistake?

INTRODUCTION: Testicular torsion is a serious surgical emergency of children. Prompt recognition and exclusion of other acute scrotal causes are essential for avoiding testicular loss. The aim of this study was to evaluate 10 years of experience with testicular torsion, point out our pitfalls in diagnosis and management, determine our likelihood of performing orchiectomy for potentially reversible injury. MATERIAL AND METHOD: Records of patients operated for testicular torsion in the last decade were reviewed retrospectively. Clinical findings, symptoms, type of surgery, accuracy of radiological evaluation, and the outcome were analyzed. Orchiectomy specimens were reevaluated and histologically graded to determine the existence of previously undetermined low-grade injury. RESULTS: In total, 107 children were operated for testicular torsion. Presentation included pain 96 (89.7%), scrotal swelling 48 (44.8%). Doppler ultrasonography was performed in 96 patients with false-negative results in 26 (27%). Testicular salvage occurred in 65 (60.7%) patients of which 6 (9.2%) developed subsequent testicular atrophy. Forty-two (33.9%) patients were treated with orchiectomy and histologic reevaluation, and grading of the specimens revealed 4 (9.7%) low-grade injury which indicates a potential of reversible injury. Seventeen (13.7%) patients had normal testicular anatomy in surgery. CONCLUSION: Surgical exploration is mandated in case of clinical suspicion for testicular torsion even with a normal flow Doppler ultrasound. Macroscopic evaluation does not always correlate with microscopic findings, and a decision according to it may result in excision of potentially viable testis. Further studies are required to determine the actual risk of contralateral autoimmune damage and increase the rate testicular salvageability after testicular torsion.

Comparing the fecal continence scores of patients with anorectal malformation with anorectal manometric findings.

BACKGROUND: Patients undergoing surgery for anorectal malformation (ARM) may have defecation-related problems throughout their lives, even if they are perfect treated surgically. Assessment methods are needed to standardize the clinical outcomes of patients with ARM. The aim of this study was to compare the scoring systems (SS) with the anorectal manometry (AM) findings. METHODS: The data of patients operated on for ARM were examined. Holschneider's, Rintala's, Krickenbeck's and Peña's questionnaires were executed to the patients and AM was performed. RESULTS: Our study was completed with 23 patients. There was a statistically significant relationship between the anal resting pressure and Holschneider's questionnaire (HQ). There was a statistically significant relationship between the area under the curve in the maximum voluntary squeeze pressure-time graph (AUC) and the HQ and Rintala's questionnaire (RQ). A statistically significant difference was found between HQ and RQ scores and high type and low type of ARMs. CONCLUSION: In our study, based on AM data, it was found that the use of HQ and RQ from the four SS we compared could be more effective in patients' follow-up. It was concluded that Peña's questionnaire and Krickenbeck's questionnaire should be used to determine the bowel management program of the patients rather than patients' follow-up. LEVELS OF EVIDENCE: Level II.

Diagnostic Value of Serum Urokinase-Type Plasminogen Activator Receptor in Children With Acute Appendicitis.

OBJECTIVES: Acute appendicitis (AA) is the most common surgical emergency in children. The accurate and timely diagnosis of AA in children can be challenging, and delayed diagnosis rates have been reported to range from 5.9% to 27.6%. Although combining clinical history and repeated physical examination with laboratory tests and radiographic imaging modalities help reach the diagnosis, novel biomarkers can support the surgeons' decision as well. The aims of this study were to evaluate a new plasma marker, urokinase-type plasminogen activator receptor (uPAR), to improve diagnostic accuracy in AA patients, and to determine a cutoff value of uPAR, which can safely include/exclude the diagnosis of AA. METHODS: We conducted a prospective study of children who underwent surgery for AA. Patients were categorized into the following 3 groups: group 1, controls consisted of 32 healthy volunteers; group 2, patients underwent surgery for nonperforated AA (n = 35); and group 3, patients underwent surgery for perforated AA (n = 21). Blood was sampled from group 1 at the admission and from group 2 and 3 before appendectomy. Serum uPAR, white blood cell count, absolute neutrophil count (ANC), and C-reactive protein concentrations were measured. RESULTS: Urokinase-type plasminogen activator receptor, ANC, and white blood cell count values were significantly higher in group 2 and 3 than group 1, but there was no significant difference between group 2 and 3. C-reactive protein values were significantly higher only in group 3 than other groups. The cutoff value for uPAR is 2.2 ng/mL with sensitivity of 85.7% and specificity of 84.3% and ANC is 5900 cells/mm with sensitivity of 91.1% and specificity of 96.9% to diagnose appendicitis. The specificity was 81.3% and sensitivity was raised to 98.2% when evaluated together. CONCLUSIONS: The incorporation of uPAR count and ANC could be a strong predictor of AA in children.

Pentraxin-3: A strong novel biochemical marker for appendicitis in children.

INTRODUCTION: Appendicitis is the most common surgical disease evaluated by pediatric surgeons in the emergency department. Despite the history, physical examination, laboratory tests and imaging methods, the misdiagnosis may be observed often in children. Pentraxin-3 (PTX-3) is an acute phase protein which is produced directly in the inflammatory tissue. Our aim was to investigate the diagnostic value of PTX-3 levels in appendicitis in pediatric patients and compare it with the other serum parameters. METHODS: Eighty-eight patients (aged <18 years) were included in this study [Group 1 (n = 28) healthy volunteers, Group 2 (n = 28) patients with non-specific abdominal pain, Group 3 (n = 34) patients underwent appendectomy]. Serum white blood cell (WBC), absolute neutrophil count (ANC), neutrophil/lymphocyte ratio (NLR), C-reactive protein (CRP) and PTX-3 values were measured. RESULTS: Median serum levels of WBC were higher in Group 2 and 3 than Group 1. ANS, NLR, CRP and PTX-3 were higher in Group 2 than Group 1 and were higher in Group 3 than the other groups. The highest sensitivity was found in NLR >3.5 [94.1 (95% CI = 80.3-99.3)] and PTX-3 > 5.6 ng/mL [91.8 (95% CI = 76.3-98.1)]. PTX-3 has the highest specificity among all of the parameters [90.7 (95% CI = 79.7-96.9)]. The area under the ROC curve showed that the diagnostic value of PTX-3 was greater than any other parameter [0.979 (95% CI = 0.92-0.99)]. CONCLUSION: In this study, we have shown that PTX-3 is very useful with high sensitivity and specificity in the diagnosis of appendicitis compared to WBC, ANS, NLR and CRP as a first in the literature.

The effect of platelet-rich plasma on motility changes in experimental caustic esophageal burn.

BACKGROUND: Besides stricture formation, diminished esophageal motility after caustic esophageal burns also plays a role in the deterioration of the clinical course. In this study, we aimed to investigate the effect of caustic burn on the esophageal contractions and the effect of platelet-rich plasma (PRP) on these changes. METHODS: Twenty-one Wistar albino rats were divided into three groups [Sham operation (n = 8), caustic esophageal burn with NaOH (n = 6), PRP treatment after caustic burn (n = 7)]. After 3 weeks, esophagectomy was performed and contractions and EFS responses were evaluated in the organ bath. RESULTS: KCl- and acetylcholine-induced responses were reduced in the Burn group, but increased in Sham and PRP groups (p < 0.05). EFS responses were higher in Burn group compared to the other groups. Response with L-arginine was increased in Burn group, but decreased in PRP group. There was more decrease in the contraction in Sham and PRP groups compared to the Burn group after SNP (sodium nitroprusside) incubation (p < 0.05). L-NAME (Nω-Nitro-L-arginine methyl ester) did not change the EFS responses in the Burn group, but EFS responses were decreased significantly in Sham and PRP groups (p < 0.05). EFS responses were decreased in all groups, but more in the Sham and PRP groups after Y-27632 (Rho-kinase inhibitor) incubation (p < 0.05). CONCLUSIONS: For the first time, we demonstrated that both cholinergic and non-adrenergic non-cholinergic mechanisms are responsible for the altered motility in corrosive esophageal injury. Our results suggest that PRP treatment may be helpful in regulating the esophageal motility and decreasing altered contractions in corrosive burns. This effect may also contribute to the reduction of stricture formation, especially by reducing inappropriate contractions of the esophageal wall during the post-burn healing phase.

Importance of Clinical Decision Making by Experienced Pediatric Surgeons When Children Are Suspected of Having Acute Appendicitis: The Reality in a High-Volume Pediatric Emergency Department.

OBJECTIVE: The aim of the present study was to compare the pediatric appendicitis score (PAS), the Alvarado score (AS), white blood cell count (WBC), absolute neutrophil count (ANC), C-reactive protein (CRP) level, procalcitonin level, and ultrasound (US) data, with the appendectomy decisions of pediatric surgeons diagnosing acute appendicitis (AA) in a real-life setting; this was a top-level, high-volume pediatric emergency department (PED) in a developing country. METHODS: The study was conducted prospectively between January 2012 and June 2013 in the PED of the Tepecik Teaching and Research Hospital in Izmir, Turkey. The study was observational in nature; no attempt was made to influence indications for exploration or the timing thereof. Children aged 4 to 18 years presenting to the PED on suspicion of AA were included. The WBC, ANC, CRP level, and procalcitonin level were measured, and US was performed on all patients on admission. The PAS and AS were calculated. An operative decision was made by each pediatric surgeon who had the results of laboratory and radiological tests. The criterion standard for AA was histopathological assessment. RESULTS: Upon receiver operating curve (ROC) analysis, the areas under the ROCs (AUROCs) of the WBC, ANC, CRP level, procalcitonin level, US positivity, PAS, AS, and decisions of pediatric surgeons supported by laboratory and US data were 0.734, 0.741, 0.671, 0.675, 0.670, 0.831, 0.794, and 0.910, respectively. When US data were employed only in cases with PASs 4 to 7, the sensitivity increased but specificity decreased. The sensitivity and specificity of pediatric surgical decisions were 100% and 82.50%, respectively. The difference between the PAS AUROC and the pediatric surgeon decision-making AUROC was significant (P = 0.0393; 95% confidence interval, 0.0470-0.226). CONCLUSIONS: Good pediatric surgical decision making supported by laboratory and US data for those suspected of AA may be the most effective diagnostic tool in a high-volume PED in a developing country.

A huge duplication cyst of the ileum.

BACKGROUND: Massive unilocular intraabdominal cysts in children are rare. Alimentary tract duplications can present diagnostic and therapeutic difficulties. Although they can occur anywhere from the mouth to the anus, they are commonly seen in relation to the ileum. We herein present an unusual case of duplication cyst itself occupying virtually all of the available intraabdominal volume. It appeared to be an enteric duplication cyst of ileal origin. CASE REPORT: A 3-month-old girl was admitted to our hospital for investigation of progressive abdominal distension and biliary vomiting. Plain radiography of the abdomen showed normal air-fluid level in the stomach and paucity of gases in rest of the abdomen. Magnetic resonance imaging showed a huge, homogenous cyst extending from the xiphisternum down to the pelvis. The cyst was excised completely. Macroscopic examination and histologic findings confirmed the diagnosis of a huge enteric duplication cyst arising from the ileum. CONCLUSIONS: Enteric duplication cyst should be considered in a patient with an abdominal cystic mass. Radiologist must take into account patient age, clinical parameters, and imaging findings to identify the likely etiology of a cystic mass.

The Results of Pneumatic Balloon Dilatation Treatment in Children with Achalasia: A Single-Center Experience.

BACKGROUND/AIMS: Achalasia is a primary motility disorder characterized by a relaxation disorder of the lower esophageal sphincter. In pneumatic balloon dilatation, which is one of the treatment methods, the muscle fibers are torn with an endoscopically inflated balloon in the lower esophageal sphincter. This study aimed to evaluate the results of long-term pneumatic balloon dilatation treatment in our clinic for children diagnosed with achalasia. MATERIALS AND METHODS: Pediatric patients who underwent pneumatic balloon dilatation with a diagnosis of achalasia in our pediatric gastroenterology clinic between 2016 and 2021 were included in the study. Demographic data of the patients, clinical findings at diagnosis, and follow-up results were evaluated retrospectively. RESULTS: Ten patients who underwent 18 pneumatic balloon dilatation operations were included in the study. The mean follow-up period of the patients was 23.7 ± 14.1 months. It was observed that the procedure was performed once in 3 (30%) patients, twice in 2 (20%) patients, and 3 times in 3 (30%) patients. It is noteworthy that the diameter of the balloon used in the first procedure in patients who needed repeated operations was less than 30 mm. No complications were observed except for chest pain, which was detected in 1 patient. CONCLUSION: When the patients who needed recurrent dilatation were evaluated, it was noted that the diameter of the balloon in which the first procedure was performed in these patients was smaller. This study is an important contribution to the literature due to the scarcity of the pediatric achalasia data, in which long-term results related to pneumatic balloon dilatation are reported in Turkey.

Irrigation of peritoneal cavity with cold atmospheric plasma treated solution effectively reduces microbial load in rat acute peritonitis model.

Accurate and timely diagnosis of appendicitis in children can be challenging, which leads to delayed admittance or misdiagnosis that may cause perforation. Surgical management involves the elimination of the focus (appendectomy) and the reduction of the contamination with peritoneal irrigation to prevent sepsis. However, the validity of conventional irrigation methods is being debated, and novel methods are needed. In the present study, the use of cold plasma treated saline solution as an intraperitoneal irrigation solution for the management of acute peritonitis was investigated. Chemical and in vitro microbiological assessments of the plasma-treated solution were performed to determine the appropriate plasma treatment time to be used in in-vivo experiments. To induce acute peritonitis in rats, the cecal ligation and perforation (CLP) model was used. Sixty rats were divided into six groups, namely, sham operation, plasma irrigation, CLP, dry cleaning after CLP, saline irrigation after CLP, and plasma-treated saline irrigation after CLP group. The total antioxidant and oxidant status, oxidative stress index, microbiological, and pathological evaluations were performed. Findings indicated that plasma-treated saline contains reactive species, and irrigation with plasma-treated saline can effectively inactivate intraperitoneal contamination and prevent sepsis with no short-term local and/or systemic toxicity.

Hydatid Disease in Children from Diagnosis to Treatment: A 10-year Single Center Experience

Objective: Hydatid disease caused by Echinococcus granulosus is a parasitic zoonosis and is endemic in Turkey. Clinical manifestations vary and are related to the anatomical location. In this report, we shared the diagnosis, treatment and follow-up of hydatid disease in children with a 10-year experience. Methods: A total of fifty-seven children diagnosed with hydatid disease were analyzed retrospectively from hospital records. Diagnosis was based on clinical, serological and radiological findings. Treatment response was evaluated with clinical, radiological and serological findings. Results: The male/female ratio of 57 cases was 2.4:1 and the mean age was 113.6±45.9 months. The most common presenting complaint was abdominal pain (42.1%). While 22 (38.6%) of the cases had eosinophilia; indirect hemagglutination test positivity was detected in 27 cases (47.4%). Multiple organ involvement was present in 18 cases (31.6%). In patients with multiple organ involvement, the possibility of cysts being located in the abdomen was higher (p=0.005). Of the 50 cases (87.7%), 45 (78.9%) were operated with open surgery and 5 (8.8%) with percutaneous aspiration-injection-reaspiration method for treatment. There were 52 (91.2%) patients who were given albendazole in conservative treatment and the mean duration of treatment was 15.5±17.2 months. There were 10 cases (17.5%) who developed cyst rupture and the symptom duration was shorter than the cases without cyst rupture (p=0.017). Cyst rupture was more common in cases with dyspnea and fluid discharge from the mouth called rock water (p=0.001, p=0.005, respectively). Recurrence was observed in five cases (8.8%) during follow-up. Conclusion: In areas where the disease is endemic, despite prevention and control programs consisting of personal habits and health education, active transmission of hydatid disease is seen in children and continues to be an important public health problem. Hydatid disease should definitely be considered in the presence of suspicious radiological and clinical findings in endemic areas. Controlled clinical studies are required for diagnosis and treatment procedures.

[Our childhood cases with intussusception and pneumatic reduction]. / Cocukluk çagi invajinasyon olgularlmlz ve pnömatik redüksiyon.

BACKGROUND: Intussusception is defined as telescopic insertion of the terminal ileum in to the colon after the cecum and colon. The aim of this study was to present our experience in pneumatic reduction of intussusception. METHODS: In our study, 118 intussusception cases treated between 1996 and 2008 were analyzed. Age, gender, admission time, diagnostic/treatment methods, types of intussusception including leading point, and postoperative complications were evaluated. RESULTS: Of these patients, 76 (64%) were male and 42 (36%) were female. Mean age was 25 +/- 34 months (3-180 months). The most common clinical presentations were vomiting, abdominal pain/irritable crying and bloody stools. Intussusceptions were ileocolic in 109 (92.3%) patients, ileoileal in 7 (6%) patients, and colocolic in 2 (1.7%) patients. No mortality was noted. Fifty-three patients (45%) were treated by nonoperative reduction whereas the remainder were treated surgically. Among 65 patients operated, 13 leading points were detected. Pneumatic reduction success rate was 86%. Age significantly reduced the pneumatic reduction success rate; however, the duration between the beginning of symptoms and hospital admission and bloody stool were not effective. CONCLUSION: Intussusception can be treated by non-operative methods when diagnosed early. Our results suggest that pneumatic reduction of intussusception in the pediatric population should be considered as a first choice.

[An interesting journey of a grass inflorescence from broncho to dorsum: case report]. / Bir pisipisi otunun bronslardan sirta ilginç yolculugu: olgu sunumu.

A 15-years-old male was presented with hyperemic and painful right flank mass. His medical history was consisted of a treatment for pneumonia and hemoptysis in the other hospital five months ago. Diagnostic X-rays was showed consolidation in the posterobasal segment of right pulmonary lobe and abscess in the paravertebral muscle extending from L4-5 level. The patient was discharged after antibiotic treatment. At the second hospitalization, a grass inflorescence was discharged from the fistula. When the patient was reevaluated his history was consisted of the aspiration of a grass inflorescence eight months ago. To our knowledge, this patient represents the first case of penetration by a grass inflorescence migrated out of the lumbar region.

Modified Leadbetter-Politano Ureteroneocystostomy: A Safer Procedure.

PURPOSE: Open surgical reimplantation of ureters is a highly successful procedure, with reported correction rates of 95 to 99 percent regardless of the severity of vesicoureteral reflux (VUR). Leadbetter-Politano ureteroneocystostomy is one of the most preffered technique for open ureteroneocystostomy.  The authors report the modified Politano-Leadbetter technique with extravesical mobilization and transection of the ureter at the level of ureterovesical junction and intravesical reimplantation. Materials and Methods: Fifty-seven children with unilateral VUR, underwent modified Leadbetter-Politano ureteral reimplantation with extravesical mobilization and transection of the ureter at the level of ureterovesical junction and intravesical reimplantation. Persistence of VUR despite endoscopic correction, breakthrough infections, complications due to antibiotics, progressive renal scarring, reflux nephropathy, and parental preference were indications for open reimplantation. Operations were done by two full-time pediatric surgeons. Operation time and hospital stay of the patients, reflux persistency, voiding dysfunction and complications were recorded.  Results: No ipsilateral VUR was detected postoperatively. Mean operation time was 76.54 min (±8.76 min; range, 70-86 min) Mean duration of the hospital stay is 82.31 h (±9.78 h; range, 71-93 h). Postoperative gross hematuria was not seen in any patients. No voiding dysfunction and no late complications was encountered.  Conclusions: Modified Leadbetter-Politano technique is a good option to treat VUR with success rate up to 100% without any major complicatons such as viscus perforation and ureteral obstruction. It is a rather simple technique that require less operative time.

Clinical features and treatment of ruptured pulmonary hydatid cyst in children.

Backgroud and objectives. Rupture is the main complication of the pulmonary hydatid cyst (HC). The aim of this study was to evaluate the clinical features and treatment of ruptured pulmonary HC. METHOD: The medical records of children who had undergone surgery between January 1999 and December 2017 for pulmonary HC were retrospectively evaluated. One hundred forty seven of these patients had ruptured HC at the time of diagnosis. The gender, age at the time of diagnosis, sociogeographic status (i.e., from urban or rural population group), symptoms, affected lung region, cyst dimensions, preoperative complications, medical treatment duration, and associated morbidities were evaluated. RESULTS: The study included 649 patients with pulmonary HC. Mean age was 9,8 (2-17) years. Three hundred forty four patients were male and 305 were female. The most common symptoms were, cough accompanying mucopurulent sputum, hydropthysis and dyspnea in patients with ruptured HC. The diagnosis of all the patients were established in the light of the findings obtained from two-sided chest x-ray and CT of the thorax. Simple cystotomy via posterolateral thoracotomy was the treatment of choice. Cappitonage was not performed in any patients. Lung resection was performed only if there was an irreversible and disseminated pulmonary destruction. CONCLUSION: Rupture of the pulmonary HC is the most common and also the most feared complication. Rupture may be either intrabronchial or intrapleural. Radiologic imaging is diagnostic. Rupture of the pulmonary HC must be considered as an emergent issue. Simple cystotomy amd removal of the laminated membranes are adequate treatment of choice. Meticulous closure of the bronchial openings is mandatory to avoid prolonged air leak. Cappitonage is unnecessary.

The effect of probiotics on intestinal motility in an experimental short bowel model.

PURPOSE: To investigate the effect of probiotics on spontaneous contractions of smooth muscle isolated from jejunum and ileum of rat model. METHODS: Four rat groups were created (n=8, in each) including control (Group 1), control+probiotic (Group 2), short bowel (Group 3), and short bowel+probiotic (Group 4). Groups 1 and 2 underwent sham operation, Groups 3 and 4 underwent massive bowel resection. Bifidobacterium Lactis was administered in Groups 2 and 4 daily (P.O.) for three weeks. On postoperative week 3, rats were sacrificed, and jejunum and ileum smooth muscle were isolated for organ bath. Muscle contraction changes were analyzed before and after addition of antagonists. RESULTS: Short bowel group exhibited increased amplitude and frequency of spontaneous contractions. The addition of probiotics significantly decreased enhanced amplitude and frequency of bowel contraction in short bowel group and returned to control values. L-NNA increased amplitude and frequency of contractions in all groups. While indomethacin and nimesulide increased the amplitude in all groups, the frequency was only increased in jejunum. Hexamethonium and tetrodotoxin did not change the contraction characteristics in all groups. CONCLUSION: We suggest that early use of probiotics may significantly regulate bowel motility, and accordingly improve absorption of nutrients in short bowel syndrome.

[The role of apoptosis and protective effect of carnitine in contralateral testicular injury in experimental unilateral testicular torsion]. / Deneysel tek tarafli testis torsiyonundaki karsi testis hasarinda apoptozisin rolü ve karnitinin koruyucu etkisi.

BACKGROUND: We examined the role of programmed cell death (PCD) in the etiology of contralateral testis injury as well as the protective effect of carnitine. METHODS: Thirty-six Wistar Albino rats were used in the study. Rats were divided into six groups as control, sham, torsion-detorsion with 6- and 24-hour intervals, and torsion-detorsion-carnitine administration with 6- and 24-hour intervals. The left testes of all rats were torsioned 720 degrees. Intraperitoneal carnitine was administered to groups as 100 mg/kg one hour before detorsion. Orchiectomy was applied to the contralateral testis a week after detorsion. Testes were examined with respect to diameters of seminiferous tubules (DST), ratios of malonyl dialdehyde and Johnsen biopsy scores (JBS), and PCD ratios. Results were evaluated by ANOVA test. RESULTS: Programmed cell death ratios were significantly higher in the torsion-detorsion with 6- and 24-hour intervals groups compared to the sham group. Those increases were more prominent in the torsion-detorsion with 24-hour interval group. DST and JBS of the control group were significantly higher than in the experimental groups (p < 0.05). The protective effect of carnitine was significant in the 24-hour torsion group, while no significant difference were detected in the 6-hour torsion-detorsion-carnitine group. CONCLUSION: Increased injury and PCD in the contralateral testis was observed with prolonged exposure time in this model. It was possible to decrease the injury with carnitine.

Case Report: Isolated Renal Hydatid Cyst in a Boy

Hydatic cyst is a crucial and prevalent parasitic disease in the developing countries in the Mediterranean region. Its diagnosis is sometimes problematic because of non-specific complaints and unavailability of any positive results in a routine laboratory analysis. Isolated renal hydatid cysts are very rare. In this study, a primary left renal hydatid cyst which was found in a 12-year-old boy was presented. He was referred by another hospital to our department with a flank pain and cystic mass in left kidney. Indirect haemagglutination test (IHA) for Echinococcus was negative. Nephrectomy was performed with the diagnosis of renal cyst hydatic. Renal cyst hydatid may present with various clinical findings ranging from asymptomatic clinical course to total loss in renal function. It will be beneficial to consider a renal hydatid cyst in patients with blurred flank pain, even if IHA is negative.
