Interleukin-17 and Toll-like Receptor 10 genetic polymorphisms and susceptibility to large joint osteoarthritis.

Primary osteoarthritis (OA) is the most common type of a joint disease. It has a polygenic risk inheritance pattern and affects older people. The etiology of this disease is not fully understood.

Pulmonary myelolipoma containing osseous tissue: An unexpected finding at autopsy.

Pulmonary myelolipoma is a very rare benign tumor composed of mature adipose tissue and hematopoietic elements such as erythroid, myeloid and megakaryocytic. It usually represents accidental finding during autopsy or chest imaging, since most cases are asymptomatic. Larger masses can lead to hemorrhage, chest pain and chest organ compression.

The role of arterial hypertension in the progression of non-diabetic glomerular diseases.

Arterial hypertension (AH) per se is, together with diabetes mellitus, the most important cause of renal failure and of dialysis in the western world. AH is also a well known consequence of chronic renal disease, and at the same time one of the main factors which causes diabetic and/or non-diabetic chronic renal failure progression. AH is mostly registered in patients with focal segmental glomerulosclerosis and with membranoproliferative glomerulonephritis.

Sclerosing haemangioma of the lung in a 4-year-old child.

Sclerosing haemangioma of the lung (SHL) should be recognised as a distinct clinicopathological entity. It is a benign neoplasm, probably of epithelial origin. Clinically, the tumour is asymptomatic and shows a striking preponderance in middle-aged women.

Gentamicin concentrations in urine, cortex and medulla in an acutely obstructed kidney animal model.

Gentamicin was administered intraperitoneally, three times in 12 h to Hartley type guinea-pigs which had undergone complete unilateral ureteral obstruction with normal contralateral ureteral function for either 24 hours, 7 days or 21 days. Two hours after the last drug dose urine samples were collected from urinary bladder and obstructed ureter. Healthy and obstructed kidneys were then surgically removed from all sacrificed animals.

Similarities in the pattern of regional brain dysfunction in negative schizophrenia and unipolar depression: a single photon emission-computed tomography and auditory evoked potentials study.

1. Negative schizophrenic and unipolar depressive patients were clinically assessed. In addition to this SANS and HRSD tests were administered.

Intracardiac juvenile xanthogranuloma in a newborn.

Juvenile xanthogranuloma (JXG) presents a normolipemic non-Langerhans cells histiocytosis. JXG usually presents with cutaneous lesions. Visceral involvement is rare but may affect various organs.

Low arylsulphatase A activity in the development of psychiatric disorders.

Previous studies have suggested that arylsulphatase A (ASA) deficiency may be present in psychiatric patients. A number of patients with low ASA activity and various neuropsychiatric symptoms have been observed. Metachromatic leucodystrophy (MLD) is a disease caused by deficiency of the enzyme ASA.

Radioangioscintigraphy and Doppler echocardiography in the quantification of left-to-right shunt.

The magnitude of left-to-right shunt in 55 children with isolated congenital heart disease [atrial septal defect (ASD) or ventricular septal defect (VSD) (muscular and perimembranous)] was estimated by two methods: radionuclide quantification and Doppler echocardiography [flow (L/min) = mean velocity x area x ejection time x heart rate]. We found little difference between the magnitude of left-to-right shunt obtained with Doppler echocardiography and that with radioangioscintigraphy for a whole group of patients (N = 55, -11.42% to 12.

Expression of haematopoietic progenitor cell-associated antigen BI-3C5/CD34 in leukemia.

The expression of progenitor cell-associated antigen CD34, defined with monoclonal antibody BI-3C5, was investigated in cells from 109 patients with leukaemia. No reactivity was found in chronic leukaemias, whereas 31% of acute myelogenous leukaemia (AML) and most non-T, non-B acute lymphoblastic leukaemia (ALL) expressed CD34. Examples of BI-3C5+ AML included M1 and M2 FAB types only; all but one were myeloperoxidase positive.

Extravascular background subtraction using deconvolution analysis of the renogram.

The effect of the intravascular background in the renogram on the calculated renal retention function is known and can be removed. However, the effect of the extravascular background (EVB) has not been thoroughly investigated using patient data. By varying the size of the region of interest containing a single kidney and by deconvolving the 131I-hippuran and 99Tcm-DTPA renograms so generated, the following has been found: (a) the effect of EVB on the mean transit time (MTT) is negligible and EVB subtraction is not necessary, (b) the EVB overestimates the lower relative kidney function (RKF) and underestimates the higher RKF, so that EVB subtraction should be performed if the RKFs are asymmetric.

131I dose to the human fetal thyroid in the Zagreb district, Yugoslavia, from the Chernobyl accident.

The 131I activity was measured in 30 human fetal thyroids in Zagreb district after the Chernobyl accident. A model of radioiodine metabolism in the mother and human fetus which takes into account the age dependence of the uptake and retention of radioiodine in the fetal thyroid was developed. Having assessed that the total intake by the average mother was about 1330 Bq, a good correlation between calculated and measured fetal thyroid activities was found (r = 0.
