Risk factors for impaired neurological outcome after thoracic aortic surgery.

Background: We aimed to identify risk factors for an impaired postoperative neurological outcome after thoracic aortic surgery.

Methods: Data from all patients undergoing thoracic aortic surgery between 2010 and 2020 at our institution were collected and analyzed retrospectively. Logistic regression analysis was used to identify independent risk factors for permanent postoperative neurological deficit (ND) (stroke), which was defined as a ND lasting at least seven days.

Outcome of the frozen elephant trunk procedure as a redo operation.

Objectives: The goal of this study was to determine the outcome of patients undergoing an elective frozen elephant trunk (FET) procedure as a redo operation following previous cardiac surgery.

Methods: One hundred and eighteen consecutive patients underwent FET procedures between October 2010 and October 2019 at our centre. Patients were registered in a dedicated database and analysed retrospectively.

Anticyclic citrullinated peptide antibodies in juvenile idiopathic arthritis.

Anticyclic citrullinated peptide (anti-CCP) antibodies have been detected in patients with juvenile idiopathic arthritis (JRA), particularly in those with polyarticular JIA. We analyzed the presence of anti-CCP antibodies of the IgG class in sera of patients with defined juvenile idiopathic arthritis (JIA) of various subgroups. One hundred and fifty-nine serum samples were investigated.

The diagnostic value of anti-cyclic citrullinated peptide (CCP) antibodies in children with Juvenile Idiopathic Arthritis.

Background: Antibodies against cyclic citrullinated peptide (anti-CCP) are considered to be specific for rheumatoid arthritis (RA).

Objective: To assess the clinical significance of anti-CCP antibodies in a cohort of patients with juvenile idiopathic arthritis (JIA) and if they can be used to identify patients with an unfavourable course of disease.

Methods: 68 serum samples were investigated.

Gamma-hydroxybutyrate versus chlorprothixene/phenobarbital sedation in children undergoing MRI studies.

Background: Few clinical studies have assessed gamma-hydroxybutyrate and chlorprothixene/phenobarbital sedation in children. This prospective trial compared the two regimes in children, in particular concerning differences in recovery time.

Methods: 28 pediatric oncology patients undergoing elective MRI studies at a university hospital were randomly assigned to either receive gamma-hydroxybutyrate or chlorprothixene/phenobarbital sedation.

[Complicated malaria tropica in an infant].

We report on a five month-old infant from Cameroon, who was admitted because of febrile gastroenteritis after living in Germany for two weeks. Since the patient was somnolent, had a parasitaemia of Plasmodium falciparum of 230,000/microliter, a haemoglobin concentration of 5.3 g/dl and a thrombocytopenia, a complicated falciparum malaria was diagnosed.

Dose reduction in thorax radiography in simulated neonates with additional filtration and digital luminescence radiography.

Purpose: To determine the minimum acceptable radiation dose for an adequate image quality in thorax a.p. radiographs of neonates using mobile X-ray equipment.

Emergency medical training for dental students.

Twenty-four of the thirty-two German universities that have dental schools replied to a questionnaire survey that showed that all the schools responding held lectures on the topic "Medical Emergencies" although this is not mandatory for registration. All of the universities in the former East Germany also offered practical training sessions as part of the curriculum. The proportion of West German universities offering such courses is only 60%.

[Ultrasonography of hips in neonates].

For evaluation of the development of the hip joints in young infants, between Jun., 1988 and Oct., 1991, 522 hips of the infants under 4 months of age were studied by ultrasonography based on the method well described by Graf.

[N-acetyl-beta-glucosaminidase (beta-NAG) in urine: a parameter for early detection of diabetogenic nephropathy in childhood].

N-Acetyl-beta-D-glucosaminidase (NAG) can be found in kidney in high activity. By determination of this enzyme activity in urine nephropathies can be recognized reliably. We have measured this lysosomal enzyme in the urine (Colorimetric method by Noto) of 206 children suffering from diabetes mellitus to find out whether diabetic nephropathy can be detected as soon as possible.

[The interrelationship between the O2-dependent bactericidal mechanism and hyperbilirubinemia of newborn].

In order to investigate the influence of indirect bilirubin to O2-dependent bactericidal mechanism in adult and newborn phagocytes we use the NBT reduction activity of granulocytes and monocytes as index, by infiltrated granulocytes and monocytes in different concentration of indirect bilirubin with or without latex stimulator. The NBT reduction activity of granulocytes infiltrated in 20 mg/dl indirect bilirubin will increase slightly, compared to uninfiltrated; but with latex stimulator, the increment will decrease significantly, this change is reversible, when indirect bilirubin be washed, the stimulating capacity by latex stimulator in granulocyte will be stronger; there were no such change pattern in monocytes. Since there were a big difference in NBT reduction activity of granulocytes and monocytes between newborns, with or without latex stimulator, we can't get a satisfied result.

Peripheral dentinogenic ghost cell tumor.

A case of dentinogenic ghost cell tumor, that has originated peripherally in the jaw, is presented and the literature reviewed with particular reference to the origin of the tumor. The total number of central and peripheral cases reported in the English literature is 10 and although mucosal infiltration is common, peripheral origin of the neoplasm could be verified in only 3 cases.

[Value of serum sialic acid determination in children].

In order to find out whether sialic acid (SA) is suitable as a tumor marker this compound was determined in the sera of 48 healthy and of 168 sick children. In healthy children under six months of age lower concentrations of SA were found (x = 41 +/- 5 mg/dl) than in subjects aged six months to 18 years (x = 68 +/- 8 mg/dl). Inflammatory diseases of various etiologies lead to a significant increase in both age groups (x = 93 +/- 28 mg/dl), the same could be observed in subjects up to 14 days after surgery.

[Experimental studies on intraligamental anesthesia].

In an experimental study on animals the correlation between the pressure created by periodontal ligament injection and the distribution pattern of the anesthetic solution was examined. It was possible to demonstrate the penetration following intraligamental injection by scintiscanning of the mandibular bone. A correlation between pressure and distribution could not be established.

Retinal blood flow in diabetic children and adolescents.

A total of 209 diabetic children and adolescents aged 6-17 years (mean, 12.6 +/- 2.3 years) were examined by ophthalmoscopy, video fluorescein angiography and hemoglobin (HbA1c) test.
