Unusual Manifestation of Extraosseous Ewing Sarcoma: Report of 3 Cases.

Ewing sarcoma (ES), described as a diffuse endothelioma of the bone, is divided into two categories: osseous and extraosseous, which mainly affects adolescents. Extraosseous Ewing Sarcomas (EES) are rare tumors originating from soft tissues. Their clinical presentation depends mainly on the primary location of the tumor and are highly chemosensitive and radiosensitive. The purpose of this study was to describe the clinical characteristics and outcomes of 3 children with EES and uncommon presentation treated in our Unit. The diagnosis of EES was confirmed by biopsy and cytogenetic analysis with fluorescence in situ hybridization (FISH). Surgical excision was planned as primary treatment, followed by adjuvant chemotherapy according to EURO-E.W.I.N.G protocol. To date, all patients are alive, 1, 3 and 4 years after completion of treatment, with no signs of recurrence or metastasis.

Child abuse experience, training, knowledge, and attitude of healthcare professionals in sixty hospitals in Greece.

OBJECTIVE: This study aims to record the overall perception of healthcare professionals on child abuse and identify potential affecting factors in a nationwide scale in Greece as well as to provide information that might be useful for future educational actions. MATERIALS AND METHODS: A total of 1,185 healthcare professionals in 60 hospitals with pediatric departments across Greece participated in this cross-sectional study. Participants included pediatricians, pediatric surgeons, residents, nurses, psychiatrists, psychologists, and social workers. Sections under investigation involved experience and training in child abuse, knowledge of formal and judicial issues, clinical knowledge, and self-assessment. RESULTS: Although more than half of the participants had confronted child abuse (n=712, 60.08%), only 273 (38.34% of them) submitted reports. One third of participants reported that they had received some training (n=440, 37.13%), mainly of postgraduate nature and based on personal initiative. Of those who reported child abuse, 175 (64.10%) had been trained. Each professional category was aware of topics regarding its own interest, without adequate knowledge of other disciplines. One third of psychiatrists, psychologists, and social workers felt confident in discussing with children and parents. Relevant scores were lower in the other categories. The lower scores were recorded among nurses and residents. The training deficit and reluctance to engage with judicial issues were the main causes of avoidance to deal with child abuse. CONCLUSIONS: Focused and organized training in child abuse is crucial to create reliable professionals in the field. The internet is a considerably helpful tool. Professionalism must characterize knowledge and practice in child abuse at the same level as in other medical topics. Motivation to engage should be early inspired and developed during the graduate years.

Healthcare workers' hand hygiene knowledge and compliance evaluation, in a Greek university hospital.

OBJECTIVE: Healthcare associated infections affect both patients and employees, in terms of morbidity, mortality, and financial costs. Routine hand hygiene is the most important factor against this pestilence. Hand hygiene knowledge and compliance of healthcare workers are considered poor worldwide. Herein, we aimed to measure knowledge and compliance with hand hygiene of the healthcare workers at a university hospital. MATERIALS AND METHODS: The "WHO hand hygiene knowledge questionnaire for healthcare workers" was translated in the Greek language, and was validated linguistically, culturally, and psychometrically. Reliability, content, construct, and convergent validity were measured. A survey on hand hygiene knowledge, and compliance, based on this questionnaire, was conducted on 439 employees. RESULTS: The translated questionnaire presented good reliability, with Guttman's Lambda-6 evaluation (0.7). Content Validity Ratio was 84.6%. Confirmatory and exploratory factor analysis showed moderate construct validity. Convergent validity showed low correlation between the questionnaire items. Regarding the answers received, it was found that only 55.3% of the respondents received formal training on hand hygiene during the last three years prior to the study. Furthermore, 74.0% of them used alcohol-based solutions routinely. Only 54.3% of the participants presented an acceptable level of hand hygiene knowledge. CONCLUSIONS: The translation and validation of the WHO questionnaire resulted in an acceptable, reliable, and valid instrument. The survey showed that hand hygiene is rather a matter of habit, than of knowledge, and that there is great need of more organized training.

Mucoceles of the lesser salivary glands in neonates demonstrate a particular clinicopathological pattern and mandate urgent management.

Mucoceles of the lesser salivary glands are common benign lesions affecting all ages, most commonly appearing on the lower lip. However, mucoceles in neonates demonstrate a different clinicopathological pattern than in older children or adults and mandate urgent management. We present a case of a large mucocele on the tongue of a neonate, which impaired feeding and could block the airway. The lesion was resected on the 3rd day of life. We describe a surgical technique that facilitates this procedure. Our literature review revealed 13 neonatal lesser salivary gland mucocele cases, 7 of which were located on the tongue. All tongue cysts were large, impaired feeding and sometimes blocked the airway. Early treatment is usually imperative. Inclusion cysts outnumbered extravasation cysts. Prenatal diagnosis is important in order to arrange delivery in an organized center. Resection is the preferable procedure.

Anastomotic loop between common hepatic artery and gastroduodenal artery in coexistence with an aberrant right hepatic artery.

Anatomical variations of the hepatic arteries are not uncommon. The anomalous hepatic arterial supply is of paramount importance in hepatobiliary, pancreatic or liver transplantation and in laparoscopic surgery. We describe an unusual case of a 66-year-old Greek male cadaver, where a rare anastomosis (in the form of an enlarged arterial loop, 4.84 mm in diameter) between the common hepatic artery (6.42 mm) and the gastroduodenal artery (GDA) (4.82 mm) coexisted with an aberrant right hepatic artery (ARHA) (6.38 mm) originating from the superior mesenteric artery. The proper hepatic artery was absent. The ARHA followed a route posterior to the portal vein and the common hepatic duct, entering the liver and supplying the right hepatic segment. A hypoplastic right gastric artery emanated from the GDA. Our case report highlights the combined variations of hepatic arteries and possible anastomoses emphasizing that a thorough knowledge of the classic and variable hepatic arterial anatomy are mandatory for surgeons and radiologists performing hepatic surgery and arteriography to avoid potential iatrogenic injuries in hepatobiliary and pancreas area and further medico-legal implications.

Repair of Postoperative Abdominal Hernia in a Child with Congenital Omphalocele Using Porcine Dermal Matrix.

Introduction. Incisional hernias are a common complication appearing after abdominal wall defects reconstruction, with omphalocele and gastroschisis being the most common etiologies in children. Abdominal closure of these defects represents a real challenge for pediatric surgeons with many surgical techniques and various prosthetic materials being used for this purpose. Case Report. We present a case of repair of a postoperative ventral hernia occurring after congenital omphalocele reconstruction in a three-and-a-half-year-old child using an acellular, sterile, porcine dermal mesh. Conclusion. Non-cross-linked acellular porcine dermal matrix is an appropriate mesh used for the reconstruction of abdominal wall defects and their postoperative complications like large ventral hernias with success and preventing their recurrence.

An unusual foreign body within the appendix.

Ingestion of foreign bodies consist a quite common problem in the pediatric age group. Usually most of them traverse the gastrointestinal tract without complications and only in rare cases they get trapped within the appendix. This case report describes the ingestion of the tip of a mercury thermometer by a six-year-old girl. An elective appendicectomy was performed in order to avoid further complications. To the best of our knowledge, this is the first reported case of the tip of a thermometer within the appendix.

Embryonal/Fetal subtype hepatoblastoma: a case report.

Hepatoblastoma is the most common primary liver tumor of childhood and after neuroblastoma and nephroblastoma the third most common abdominal neoplasm in this age group. Hepatoblastoma is an embryonal tumor classified by histology as epithelial (including pure fetal subtype, mixed embryonal/fetal subtype, macrotrabecular subtype and small cell undifferentiated subtype), mixed epithelial and mesenchymal type (with teratoid and non-teratoid features) and hepatoblastoma not otherwise specified. We present a case of a five-months old girl with embryonal/fetal subtype hepatoblastoma. The clinical presentation was asymptomatic abdominal mass. Ultrasound and MRI scan demonstrated a solid hepatic tumor. She presented thrombocytosis and serum alpha-fetoprotein was increased. A left lobe hepatectomy was performed and the pathological examination revealed complete excision of a mixed embryonalfetal subtype hepatoblastoma.

Diagnosis and management of congenital neonatal chylous ascites.

BACKGROUND: Congenital chylous ascites is a rare condition that constitutes a challenge for the physician. It is defined as the accumulation of chyle into the peritoneal cavity in infants younger than 3 months. This condition is often refractory to therapy and it is responsible for serious malnutrition and immunological deficiency because of the loss of proteins and lymphocytes. MATERIAL AND METHODS: Four cases of congenital neonatal chylous ascites, were treated by our staff during the last two years. One case was treated conservatively and three with laparotomy. Two of them had intraabdominal cysts that were excised and one was treated with ligation of the left lumbar lymphatic trunk and cisterna chyli and the use of fibrin glue. RESULTS: All four cases were treated successfully. On follow up tests no one showed recurrence of the ascites. All children, except the one that treated conservatively and also had other problems due to prematurity, are growing up normally. CONCLUSIONS: Congenital chylous ascites is a complex condition. Its diagnostic evaluation is difficult and its therapy of long duration. Conservative treatment is in most cases the initial choice, but when it fails, exploratory laparotomy could provide a successful alternative.

Failure of palmaris longus muscle duplication and its clinical application.

A case of failure of palmaris longus muscle duplication was found in the left forearm of a male cadaver. Specifically, two distinct palmaris longus muscles had failed to separate, and were united from the medial epicondyle to the palmar aponeurosis. We studied the exact morphology of the abnormal muscle, which, to our knowledge, has not been reported elsewhere in the literature. It also provided data for palmaris longus muscle morphology and may have clinical implications, as the knowledge of such an anomalous muscle should be useful for hand surgeons and radiologists.

Paratubal cysts in young females as an incidental finding in laparotomies performed for right lower quadrant abdominal pain.

Paratubal cysts represent remnants of the paramesonephric or mesonephric duct, the former being more common. Most of them are asymptomatic, but they may rarely give rise to clinical problems due to enlargement or torsion. In this study, we looked for paratubal cysts or other pathological lesions of the right uterine adnexa in young females operated upon for right lower quadrant (RLQ) abdominal pain. Our material consisted of 338 white female patients aged 4-14 years. Laparotomy revealed only acute appendicitis in 283 cases, while 44 had acute appendicitis plus a coincidental paratubal cyst. Most of these cysts were smaller than 1 cm in diameter. However, 2 additional cases had torsion of a large paratubal cyst, while 5 had a ruptured corpus luteum. We suggest that a thorough search of the right adnexa for the presence of paratubal cysts during laparotomies performed for RLQ pain is a useful procedure. This approach also allows detection of other pathological lesions of the right adnexa that often produce symptoms similar to acute appendicitis.

Gallbladder disease in patients with cystic fibrosis.

We retrospectively studied 18 patients with cystic fibrosis, who underwent surgery for gallbladder disease from 1975 to 1990. A long delay between the onset of symptoms and the diagnosis was noted (mean 8.7 months). This delay was attributed to masking of the symptoms of biliary disease by the malabsorption and pulmonary symptoms seen in this patient population. We do not recommend routine intraoperative cholangiography in patients with cystic fibrosis and gallbladder disease. Cystic fibrosis is a disease with progressive pulmonary deterioration. Cholecystectomy can be performed in these patients with relative safety if careful preoperative and postoperative care is provided. We recommend early operative intervention in the patient with gallbladder disease and cystic fibrosis.
