Gastroenteric parasite of wild Galliformes in the Italian Alps: implication for conservation management.

This study provides insights about the diversity, prevalence and distribution of alpine wild galliformes gastrointestinal parasite community, trying to fill a gap in the scientific information currently available in scientific literature. The analysis included three host species: 77 rock partridge (Alectoris graeca saxatilis), 83 black grouse (Tetrao tetrix tetrix) and 26 rock ptarmigan (Lagopus muta helveticus) shot during the hunting seasons 2008-2015. Parasites isolated were Ascaridia compar, Capillaria caudinflata and cestodes. The rock ptarmigan was free from gastrointestinal parasites, whereas the most prevalent helminth (37%) was A. compar in both black grouse and rock partridge. C. caudinflata occurrence was significantly higher in black grouse (prevalence = 10%, mean abundance = 0.6 parasites/sampled animal) than in rock partridge (prevalence = 1.20%, mean abundance = 0.01 parasites/sampled animal). Significant differences were detected among hunting districts. A. compar was found with a significant higher degree of infestation in the hunting districts in the northern part of the study area whereas cestodes abundance was higher in Lanzo Valley. Quantitative analysis of risk factors was carried out using a generalized linear model (GLM) only on the most common parasite (A. compar). Latitude was the only factors associated with infestation risk (OR = 52.4). This study provides information on the composition and variability of the parasite community in the alpine Galliformes species.

A novel HLA allele, HLA-A*02:393, identified in a two generation Italian family.

HLA-A*02:393 differs by a single nucleotide substitution from both A*02:26 (A524G) and from A*02:40:01 (T527A).

HLA-DR5 antigen. A genetic factor influencing the outcome of hepatitis C virus infection?

BACKGROUND: Prognosis may be quite different among individuals infected with hepatitis C virus (HCV): a chronic liver disease is believed to occur in half the patients while in the other half there are no signs of histologic progression of liver damage. The host immune response might play an important role in such different outcomes. A relationship has been shown between HLA genes and immune response to viral hepatitis B, but to our knowledge, no evidence of an association with HCV has been reported so far. We investigated whether HLA class II alleles might influence the outcome of HCV infection. METHODS: Eighty-seven individuals, positive for anti-HCV by second-generation enzyme-linked immunosorbent assay and recombinant immunoblot assay tests, enrolled from May 1, 1991, to June 31, 1992, were evaluated. Thirty-six were symptom-free subjects found to have HCV antibodies when screened for blood donation: they all had normal results of liver function tests, normal results of physical examination, and normal hepatobiliary ultrasonography. Fifty-one were patients diagnosed as having a chronic liver disease by percutaneous liver biopsy specimen; histologic assessment was chronic persistent hepatitis in 15, chronic active hepatitis in 28, and liver cirrhosis in eight. A group of 231 donors of platelets and bone marrow, negative for anti-HCV, was used as a control population. All participants were typed for HLA class II antigens (DR and DQ) using National Institutes of Health recommended microlymphocytotoxicity test and were followed up by means of alanine aminotransferase and HCV testing for at least 1 year. RESULTS: Frequency of HLA-DR5 antigen was higher in symptom-free anti-HCV-positive individuals (52.8%) than among HCV-related patients with chronic liver disease (13.7%). The difference was statistically significant (corrected P value = .005; 95% confidence interval, 19.6% to 58.6%); between DR5 and long-term evolution of hepatitis C, there was a negative association (relative risk = 0.142). Moreover, frequency of HLA-DR5-positive subjects appeared to be inversely proportional to severity of liver disease (52.8% in symptom-free patients, 26.6% in patients with chronic persistent hepatitis, 10.7% in patients with chronic active hepatitis, and 0% in patients with liver cirrhosis, P < .001). CONCLUSIONS: Our results point to a strict relationship between HLA haplotype and ability of immune response to influence the outcome of HCV infection. Presence of HLA-DR5 antigen appears as a protective factor against a severe outcome of chronic infection, being correlated with a benign evolution of the infection, often asymptomatic, or a less severe chronic liver disease.

[The diagnosis and therapy of esophageal perforation or rupture in infancy and childhood]. / Zur Diagnostik und Therapie der Osophagusperforation bzw. -ruptur im Säuglings- und Kindesalter.

Oesophageal perforation or rupture is rare in childhood; recently there has been an increase, mostly due to the more frequent use of endoscopy in neonates. The prognosis depends largely on early diagnosis and the type of treatment. The author has seen eight children, aged between one day and nine years, with oesophageal lesions. Of these, six had a perforation and two a rupture of the oesophagus. The problems of diagnosis and treatment and their complications are discussed with reference to these patients. Stress is laid on the importance of early diagnosis. In children, contrary to the case in adults, conservative treatment is often possible.

[Diagnosis and therapy of non-parasitic splenic cysts in children]. / Zur Diagnostik und Therapie nichtparasitärer Milzzysten bei Kindern.

Splenic cysts of various types are rare surgical abnormalities. The diagnostic and therapeutic procedures are discussed with special reference to the author's clinical material consisting of six children with non-parasitic cysts. Sonography and, in special cases, CT are the most important methods of examination. The desirability of conserving the spleen, while removing the cyst, is stressed.

Teratoma of the umbilical cord. Case report with review of the literature.

Teratomas of the umbilical cord are very rare lesions. We found only five cases in the literature from 1887 to 1993, the latest reported in 1985. We report a case of a 10 x 7 x 5-cm mass located just at the end of an omphalocele in the umbilical cord of a full-term baby. The mass exhibited something like a cranial and a caudal pole, and tissues of all three germinal layers could be found, but there were no skeletal structures. Therefore, this lesion was diagnosed as a teratoma of the umbilical cord. We review the literature and discuss the relationship between the teratoma of the umbilical cord and the holoacardius amorphus.

Bioavailability of oral antibiotics in children with short-bowel syndrome.

Absorption of orally administered antibiotics (two aminopenicillins, cephalexin, trimethoprim-sulfa) was investigated in five children with sizeable resection of small bowel in the neonatal period. The absorption was proportional to the length of the remaining bowel and independent from the resected part of the gut. For cephalexin and trimethoprim a reduction of the absorption of 10% to 50% was observed, still resulting in therapeutic serum concentrations. The absorption of aminopenicillin was reduced approximately 10% of the usually achievable concentrations. Our data suggest that oral cephalexin and trimethoprim-sulfa can be used therapeutically in children with short-bowel syndrome. If aminopenicillin is indicated, parenteral therapy is advisable.

Closure of gastroschisis by mesh skin grafts in problem cases.

Closure of gastroschisis can be achieved by primary adaptation of the abdominal wall, by implanting a dura patch or by covering the protruding gut with a silastic pouch. In the Pediatric Surgical Department of the University of Innsbruck this last method was used in 14 of 18 cases during the last 8 years. In three children multiple complications and infection resulted in the necessary removal of the silastic pouch from the still protruding gut. Lacking any other alternative, the defect was covered with mesh skin grafts, which took well and permanently closed the abdominal wall.

Recent evaluation of prognostic risk factors in esophageal atresia--a multicenter review of 223 cases.

In this study, 223 cases of esophageal atresia (Type IIIb: 85.7%; Type II: 5.8%; Type IIIc: 4.0%; Type IIIa: 2.2%; Type IV: 2.2%) from 6 pediatric surgery centers of Austria, were retrospectively examined for the following parameters and their influence on the prognosis: Birth weight (2494.7 +/- 702.0 g), gestation week (range 27-42 weeks; mean 37.3 +/- 3.1 weeks), sex (male: n = 128; female: n = 95), long-gap atresia (> or = 2 cm: n = 33), Tracheomalacia (n = 16), associated malformations (n = 122; cardiac 27.4%, renal 17.9%, skeletal 17.0%, anal: 10.3%, intestinal 9.9%, mediastinal 7.6%, chromosomal 2.2%), preoperative aspiration (n = 92), pneumonia (n = 96), anastomotic insufficiency (n = 45), empyema (n = 5), mediastinitis (n = 8), sepsis (n = 32), other medical complications (n = 122, in 80 infants), other surgical complications (n = 57). The mortality rate was 41.3% overall, from 1975 to 1991; however, it was 25% from 1987 to 1991 and 0% in 1991. A statistically significant correlation was found between prognosis and the following factors: Cardiac malformations (p = 0.0001), medical complications except aspiration and pneumonia (p = 0.0001), empyema (p = 0.0081), mediastinitis (p = 0.0214), and sepsis (p = 0.0295). These 5 significant factors were given different points and a prognostic score was calculated by the addition of these points. This score was predictive for survival in 90.6% of cases and for mortality in 94% of cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Long-term results of Rehbein's procedure: a retrospective study in German-speaking countries.

AIM: In contrast to other countries, no collective study of Rehbein's procedure in German-speaking nations has been performed. Therefore, our intention was, analogously to Goto and Ikeda's (10) Japanese study in 1984, Kleinhaus's (13) study on Swenson's procedure in 1979, Bourdelat's (2) French-Canadian investigation into Duhamel's technique in 1997 and Martuciello's (11) and Teitelbaum's (16) follow-up in the year 2000, to perform a follow-up study of Rehbein's technique of deep anterior resection. METHODS: The data of 200 patients from 22 German-speaking centers in Switzerland, Austria and Germany were collected. These data were gathered by questionnaire and the children were followed up in the individual participating hospitals for at least 3.5 years after the procedure. The procedure was performed between 1993 and 1997, over a 5-year period. The questionnaire contained 74 items including anamnestic data, diagnostic postoperative treatment and reoperations. RESULTS: Concerning the incidence of anastomotic leaks and resolving anastomotic strictures there was no significant difference between the results in our series and those of the collective analyses made by Hofmann von Kap-herr (7), Holschneider (9) and Sherman (18). In 6.6 % of the 191 patients an anastomotic leak and in 9.9 % a rectal stricture, which had to be dilated, was observed. Concerning late complications, 22.8 % of the children suffered from constipation, 4.3 % from encopresis, 10.6 % from enterocolitis and only 0.5 % from enuresis. The frequency of constipation diminishes over the years. A comparison of the different large series in the literature clearly shows that the incidence of constipation is higher after Rehbein's procedure and the frequency of urinary incontinence and encopresis higher following Swenson's, Soave's and Duhamel's techniques. The incidence of enterocolitis is less after Rehbein's procedure than after Swenson's, Soave's and Duhamel's techniques. CONCLUSIONS: The different results in the literature are due to the individual experience of the author, the very different follow-up methods and the date of follow-up. Therefore, the different results are hard to compare with our study. Nevertheless, Rehbein's anterior resection still could be presented as an adequate and important method to treat Hirschsprung's disease.

[Treatment of traumatic splenic rupture in children]. / Behandlung der traumatischen Milzruptur im Kindesalter.

The introduction of new techniques for reducing blood loss in operations on parenchymatous organs and of ultrasonography for screening the traumatized spleen and monitoring therapeutic management have made it possible to preserve this organ following injuries in childhood with increasing success over the past few years. An analysis of a sample of 48 children with splenic rupture (33 boys, 15 girls, aged between eleven months and four years) treated in our department between 1974 and 1989 illustrates this change of approach. 26 patients were splenectomized, in 14 cases the spleen was partly preserved, and 8 were just monitored.

[Invagination as a complication of malignant lymphoma]. / Invagination als Komplikation beim malignen Lymphom.

Benign or malignant neoplasms are usually the underlying pathological factor initiating intussusception in the older child. Two cases of non-Hodgkin lymphoma are reported. The surgical procedure and chemotherapy are discussed.

Foot deformities in adolescents and young adults with spina bifida.

Spina bifida is generally accompanied by a high incidence of foot deformities. The goal of management is to achieve a plantigrade foot. Deformities are related to the level of the lesion. With thoracic lesions, the most frequent deformity is an equinus lesion (55%), a club foot with mid-lumbar lesion (87%) and a calcaneal foot with sacral lesions (34%). No deformity was present in 56% of feet in sacral lesion children. Club foot surgery before the age of 2 years entails a high rate of recurrence (78%), necessitating redo surgery. A calcaneo-valgus deformity developed in 45% of ambulating patients with sacral lesions requiring operative stabilization of the foot. Patients with sacral lesions were almost the only ones who remained ambulators. Ambulation was not seen to be related to foot deformities in adolescents and young adults.

[The chronically altered appendix in children. Cooperative work of the Austrian Society for Pediatric Surgery]. / Die "chronisch veränderte" appendix beim kind. Gemeinschaftsarbeit der Osterreichischen Gesellschaft für Kinderchirurgie.

In this multicentric study the anamnestic data and parents questionaires of 2-29 children were evaluated, whose appendix vermiformis at the time of operation showed no signs of inflammation. 31,1% macroscopically showed cicatrisation or fasciation, in 13,7% other enteral or gynaecological (1%) findings were present. In 1194 of the cases of patho-histological examination of the appendix had been made of which 36.4% were negative, 37.7% showed cicatrisation, 15,0% oxyuriasis and 10,4% coproliths. In the discussion of the significance of the chronically altered non-inflamed appendix we compared patients with and without macroscopical or microscopical alterations. We came to the conclusion that the probability-index as to sex, duration of symptoms, complexity of symptoms, incidence of postoperative well-being, proved the chronically altered appendix not to be an illness per se, but the result of spontaneously arrested inflammation. Since the rate of children admitted with a perforated appendix is high (15-20%) in comparison with the rate of complications after removal of non-inflamed appendices (2,9%), we believe that according to the diagnostical problems the principle can be maintained: in dubio pro operatione.

[Omphalocele and gastroschisis in Tirol-incidence and epidemiology 1985-1996]. / [Omphalozele und Gastroschisis in Tirol - Inzidenz und Epidemiologie 1985-1996]

There are basic differences between the Dutch and the Austrian systems of prenatal care, care during birth and postpartum care: whereas in the Netherlands every effort is made to keep care within the bounds of the eerste lijn - primary health care with midwives and general practitioners as primary providers - in Austria the federal 'family relief fund' and the 'mother and child passport' program have created an elaborate system in which care during pregnancy is not only free but providing antenatal care brings extra payments to the doctor and taking it brings extra money to the pregnant woman. The workings of both systems and the roles of midwives, doctors, hospitals and health insurers are explained and discussed.

[Infections of the cerebrospinal fluid shunt]. / Ventilinfektionen.

The treatment of infectious complications of implanted foreign bodies into the CNS is unsatisfactory. In the majority of these patients staphylococci are responsible for these infections which elicit only a smoldering inflammatory response with poor penetration of antibiotics into the CSF. It is also very difficult to eradicate staphylococci from the surface of silastic material by antibiotics. Fosfomycin was investigated in the treatment of CSF infections in patients with infected ventriculoatrial shunts. Fosfomycin exhibits a potent antimicrobial activity against staphylococci; this drug also showed a favourable penetration into the CSF in moderately inflamed meninges. A 10 days therapeutic course with fosfomycin plus oxacillin or cefamandole and gentamycin in combination with external drainage of the CSF into a closed system made it possible to exchange all parts of the system in one session without reinfection. This procedure was followed by the same antibiotic regimen postoperatively for 10-14 days. Under this treatment schedule therapeutic results have been considerably better compared to previous treatment modalities.

Congenital colonic atresias.

8 cases of congenital colonic atresias treated between 1968 and 1985 are presented. Questions regarding the aetiology of this rather rare anomaly are discussed. The interference with the mesenteric blood supply often as a result of intrauterine abdominal accidents seems to be a plausible explanation for most cases. We saw a high incidence of associated malformations not stated by other authors. Classification of atresias, diagnostic proceedings and operative management are discussed. The mortality of 50% can probably be lowered by the progress in total parenteral nutrition.

[Circumcision--yes or no?]. / Zirkumzision--Ja oder nein?

The indication for a circumcision is critically reviewed. Two different operations are shown. In babies the foreskin should not be retracted because a certain conglutination is physiological at this age.
