RESUMEN

BACKGROUND/AIMS:  Gastric outlet obstruction (GOO) is a rare condition in childhood, with the exception of infantile hypertrophic pyloric stenosis (IHPS). However, no classification exists from a pediatric gastroenterologist's perspective. MATERIALS AND METHODS:  The patients with a diagnosis of GOO between 2009 and 2020 were reviewed retrospectively. We classified the patients according to GOO: presence of clinical findings accompanied by radiological and/or endoscopic findings; clinical status: intractable nonbilious postprandial vomiting alone or with abdominal pain, early satiety, weight loss, postprandial abdominal distension, and malnutrition; radiology: delayed gastric emptying and dilated stomach; endoscopy: nonbilious gastric contents after 6-8 hours of emptying and/or failed pyloric intubation; physical examination: visible gastric peristalsis. RESULTS:  A total of 30 GOO patients (15 patients with IHPS, 1 patient with annular pancreas, 4 patients with gastric volvulus, 2 patients with duodenal atresia, 2 patients with antral web, 1 patient with late-onset hypertrophic pyloric stenosis (LHPS) had surgical treatment, and remaining 5 patients had medical treatment) were enrolled to the study. The median age was 8 months (range: 3 months-16 years), and 14 patients were female. Mitochondrial disorders, LHPS, metabolic disorders, and eosinophilic gastrointestinal system diseases were added to Sharma's GOO classification, and the classification has been expanded. CONCLUSION:  This is the first and largest study of GOO in children. From the perspective of pediatric gastroenterology, new diseases will be addressed, and definitions will be highlighted with our classification for GOO in childhood.

RESUMEN

Acute kidney injury (AKI) caused by ischemia and, exogenous or endogenous nephrotoxic agents poses a serious health issue. AKI is seen in 1% of all hospital admissions, 2-5% of hospitalizations and 67% of intensive care unit (ICU) patients. The in-hospital mortality rates for AKI is 40-50, and >50% for ICU patients. Ischemia-reperfusion (I/R) injury in the kidney can activate inflammatory responses and oxidative stress, resulting in AKI. The common endpoint in acute tubular necrosis is a cellular insult secondary to ischemia or direct toxins, which results in effacement of brush border, cell death and decreased function of tubular cells. The aim of the present study was to assess if the reported antioxidant and anti-inflammatory agent lupeol can exert any effects against renal I/R damage. In total, 24 Wistar Albino rats were randomly assigned into four groups of 6, namely Sham, lupeol, ischemia and therapy groups. In the lupeol group, intraperitoneal administration of 100 mg/kg lupeol was given 1 h before laparotomy, whilst only laparotomy was conducted in the sham group. The renal arteries of both kidneys were clamped for 45 min, 1 h after either intraperitoneal saline injection (in the ischemia group) or 100 mg/kg lupeol application (in the therapy group). The blood samples and renal tissues of all rats were collected after 24 h. In blood samples, blood urea nitrogen (BUN) was measured by the urease enzymatic method, and creatinine was measured by the kinetic Jaffe method. Using ELISA method, TNF-α and IL-6 levels were measured in the blood samples, whereas malondialdehyde (MDA), glutathione (GSH), caspase-3 levels were measured in kidney tissues. In addition, kidney histopathological analysis was performed by evaluating the degree of degeneration, tubular dilatation, interstitial lymphocyte infiltration, protein cylinders, necrosis and loss of brush borders. It was determined that renal damage occurred due to higher BUN, creatinine, MDA, TNF-α and caspase-3 values observed in the kidney tissues and blood samples of rats in ischemia group compared with the Sham group. Compared with those in the ischemia group, rats in the therapy group exhibited increased levels of GSH and reduced levels of BUN, TNF-α, MDA. Furthermore, the ischemia group also had reduced histopathological damage scores. Although differences in creatinine, IL-6 and caspase-3 levels were not statistically significant, they were markedly reduced in the treatment group. Taken together, these findings suggest that lupeol can prevent kidney damage as mainly evidenced by the reduced histopathological damage scores, decreased levels of oxidative stress and reduced levels of inflammatory markers. These properties may allow lupeol to be used in the treatment of AKI.

RESUMEN

Familial Mediterranean fever (FMF) is the most common inherited autoinflammatory disorder, characterized by recurrent and self-limiting episodes of fever and serosal inflammation. Recurrent serositis may rarely lead to the formation of adhesions in the peritoneum, which may result in mechanical bowel obstruction. The symptoms, such as abdominal pain and vomiting, may mimic typical FMF attacks, resulting in misdiagnosis and severe morbidity, including strangulation and intestinal necrosis. Physicians are generally aware of other complications associated with FMF but reports on peritoneal adhesions and intestinal obstruction in English-language literature are inadequate to increase clinicians' awareness. Therefore, it is crucial to meticulously evaluate FMF patients presenting with abdominal pain and ileus because these symptoms could be due to adhesive small-bowel obstruction (ASBO). Furthermore, patients presenting with ASBO without a history of abdominal surgery should also be thoroughly evaluated, especially as it could be an initial presentation for an autoinflammatory disease. Herein, we present a pediatric case of FMF with the M694V homozygous mutation, complicated by ASBO while under colchicine treatment. Additionally, we provide a comprehensive review of the available literature on ASBO in FMF.

RESUMEN

Purpose: This study aims to share our experiences and problems, and to suggest solutions as pediatric surgeons who took part in the teams that went voluntarily to the region hit by the Kahramanmaras earthquake during the first 7 days after the disaster. Methods: This study conveys our observations made at Kahramanmaras Sütçüimam University Faculty of Medicine Hospital, where we worked as a volunteer team between February 7 and 14, 2023. Results: During the first few days, there were registration problems due to lack of electricity, water, and internet, as well as issues with sterile surgical environments. In the following days, a lack of auxiliary health personnel was revealed as the main difficulty. Conclusion: Since coordination is important when working as a team in the aftermath of an earthquake, staff from the same center should be deployed together if possible, and a team leader should be selected. Alternative recording systems should be established in case of power outages and computer problems. Secretaries, auxiliary health staff, and technicians should be included in the team in addition to doctors and nurses.

RESUMEN

BACKGROUND: The rate of bladder injury during inguinal hernia repair in children is not well known. However, it is known that bladder injury during childhood inguinal hernia repair places a serious morbidity burden on children. We sought to determine an algorithm to avoid accidental bladder injuries. METHODS: Reports that included pediatric patients with inguinal hernias containing the bladder were searched. Keywords and mesh term searches were conducted in the MEDLINE, Scopus, and Web of Science databases. We reviewed our clinical records and found that two patients had inguinal hernias containing the bladder. RESULTS: Nineteen articles reporting on 26 patients diagnosed with the presence of the bladder within the inguinal canal from 1962 to 2021 were included in this article. Our two patients were added to this group. Diagnoses were made incidentally during genitourinary radiological examinations (n = 3), intraoperatively during hernia repair (n = 7), or due to clinical symptoms and findings (n = 18) after standard hernia repair. Bladder augmentation was required for three patients. CONCLUSIONS: During the operation, if there is any suspicion regarding the presence of the bladder in the inguinal region, we suggest performing a preoperative cystogram to confirm the position of the bladder and its injury. We recommend that the sac should be opened and the contents inspected before performing transfixion during high ligation of the hernia sac.

RESUMEN

PATIENT: Female, 4 FINAL DIAGNOSIS: Tumoral calcinosis Symptoms: Hard immobile mass Medication: - Clinical Procedure: - Specialty: Surgery. OBJECTIVE: Congenital defects. BACKGROUND: Tumoral calcinosis is an uncommon condition associated with the deposition of painless calcific masses. It is more common in childhood or early adolescence of African-American females. CASE REPORT: We present a case of a 4-year-old girl with tumoral calcinosis treated surgically. The case is rather rare in terms of the age of the patient and the localization of the masses (gluteal site). In our patient, the biochemical findings were normal, except for hyperphosphatemia and elevated alkaline phosphatase. CONCLUSIONS: Total excision appears to lead to a good clinical outcome and a low incidence of local relapse.

RESUMEN

BACKGROUND: The management of giant omphalocele (GO) presents a major challenge to pediatric surgeons. Current treatment modalities may result in wound infection, fascial separation, and abdominal domain loss. We report a GO infant who required a delayed closure and was managed using sterile incision drape and polypropylene mesh. METHODS: A 3080 g full-term female infant was born with a GO. The skin was dissected from the fascia circumferentially without opening the amniotic sac and the peritoneum. Subsequently, two polypropylene meshes of 10 x 10 cm in diameter were sutured to each other. Inner surface of the mesh silo was covered with sterile incision drape. This texture was sutured to the fascial margin. Then, the skin was sutured to the mesh and the silo was closed from the side and above. On the 4th day the reduction was started using thick sutures without anesthesia. This procedure was repeated on every 3rd day. When it came closer to the skin margins, constriction was performed using right angle clamps, each time placed 2 cm proximally to the previous sutures in a circular manner. Silo was removed easily and the skin, subcutaneous layers, and fascia were then approximated on the 42nd day. RESULTS: The postoperative course was uneventful and the infant was well with left inguinal hernia repaired in the 3rd month. CONCLUSION: The method we used can be performed at bedside and without the application of anesthesia, but should be tried on more patients to determine its effect.

RESUMEN

A newborn female infant delivered after a normal pregnancy was found to have a large sacrococcygeal mass. Imaging and laboratory studies suggested this was a sacrococcygeal teratoma. On the 16th day of age, the tumor was completely removed. Histopathologic examination of the tumor showed malignant Triton tumor (MTT). Thus, we describe a female newborn without a family history of neurofibromatosis with an MTT that mimics a sacrococcygeal teratoma. To our knowledge, this is the first report of a sacrococcygeal MTT detected in a neonate.
