Plexiform schwannoma of esophagus in a child with neurofibromatosis type II.
No full textSchwannoma is a benign neoplasia of the peripheral nerve sheath. Its localization in the gastrointestinal tract, and in particular in the esophagus, is very rare. According to the existing literature esophageal schwannoma has been reported so far only in adult patients. We report the case of an 11 year old patient with neurofibromatosis, type 2, who underwent surgical excision of a plexiform schwannoma of the esophagus
Intradiaphragmatic hybrid lesion in an infant: case report.
No full textHybrid lesions have elements of both congenital cystic adenomatoid malformation and bronchopulmonary sequestration. We report an unusual case of an infant treated for an intradiaphragmatic hybrid lesion. Although computed tomography remains the criterion standard imaging examination for planning the operation, the exact localization of such lesions may be discovered only at surgical exploration
Successful management of congenital chylous ascites with early octreotide and total parenteral nutrition in a newborn
No full textCongenital chylous ascites (CCA) is a rare disease that results from maldevelopment of the intra-abdominal lymphatic system. Few cases have been described and no gold standard treatment has been defined so far. Octreotide, a somatostatin analogue, has been used for the treatment of CCA, but always after a failed conservative approach with fasting, total parenteral nutrition (TPN) or medium chain triglyceride (MCT) feeds. We report the case of a newborn with CCA treated by fasting, TPN and octreotide for a period of 15 days until the abdominal distension was successfully reduced at which point treatment was switched to an MCT formula. On day 25 the patient was breastfed and was discharged on day 33. No recurrence of chylous ascites was noted. Our experience highlights the successful treatment with TPN and octreotide as the first step for the conservative approach of CCA in a newborn, reducing the length of treatment and hospitalisation
Peculiar type 1 congenital pyloric atresia: a case report.
Full text linkPyloric atresia (PA) is a very rare condition. Its incidence is approximately 1 in 100,000 newborns and constitutes about 1% of all intestinal atresias. We describe the neonatal course of a peculiar case of type 1 pyloric atresia, in which the pyloric membrane was connected to a second duodenal membrane through a virtual duodenal lumen in a premature newborn. The atypical variant required an unusual side to side gastroduodenostomy. We emphasize the importance of a prompt diagnosis to avoid potentially fatal complications and to warrant a good outcome even in the presence of a strange form of PA in the neonatal period
Extrinsic colonic obstruction by congenital fibrous band in an infant
No full textThe finding of a congenital fibrous band during laparotomy for intestinal obstruction is extremely rare. Preoperative diagnosis is challenging and no characteristic radiological findings have been described. We report the case of a premature baby in whom incomplete intestinal obstruction was due to a congenital band originating from the duodeno-jejunal flexure and extending across the ascending colon
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Sacrococcygeal teratoma. Outcome and management. An analysis of 17 cases.
No full textAIMS: The authors compare their experience of 17 cases of sacrococcygeal teratoma (SCT) with the literature in an attempt to clarify the natural history of this tumor and to identify factors related to its prognosis and management. METHODS: The obstetrical, neonatal and surgical data were analyzed for 17 cases of SCT observed between July 1985 and December 1998. RESULTS: Three fetuses died in utero or shortly after birth. In the remaining 14, the tumors were removed. Twelve of the infants are currently tumor-free, with good sphincter control and lower-limb function. The remaining two died: one had a malignant tumor, and the other had a recurrence of an embryonal carcinoma. Recurrent tumors (mature histotypes) were also removed from two of the 12 patients who survived. CONCLUSIONS: Benign SCTs generally have favorable prognosis. Negative prognostic factors for SCT include solid tumors, those detected early in pregnancy, malignant histotypes, polyhydramnios, placentomegaly, and fetal hydrops
