Expression of 60-kD Heat Shock Protein Increases during Carcinogenesis in the Uterine Exocervix
2002
<i>Objectives:</i> The aim of the present study was to determine the presence and expression of the 60-kD heat shock protein (HSP60) in the dysplasia-carcinoma sequence in the uterine exocervix and to evaluate its diagnostic and prognostic significance. <i>Methods and Results:</i> We performed Western blot and immunohistochemical analyses on biopsies from 40 cases, consisting of 10 normal exocervical biopsies, 10 low-grade squamous intraepithelial lesions (L-SIL), 10 high-grade squamous intraepithelial lesions (H-SIL) and 10 cancerous exocervices (G2 grade). The immunohistochemical results were quantified by computer-assisted image analysis. Western blot analysis sho…
The campomelic syndrome: review, report of 17 cases, and follow-up on the currently 17-year-old boy first reported by Maroteaux et al in 1971.
1983
We report 17 cases of the campomelic syndrome (CS) and a follow-up of one of the original patients of Maroteaux et al who is now 17 years old. Our review is based on 97 patients, including our own. An infant with the CS presents at birth with spectacularly short and bowed femora and tibiae. The initial chest radiograph confirms the diagnosis by demonstrating extremely small bladeless scapulae and hypoplastic pedicles of many thoracic vertebrae. Ossification of the sternal segments, pubis, talus, and knee epiphyses is also retarded. Usually the hips are dislocated and talipes equinovarus deformities are present. There is a small chondrocranium and a disproportionately large neurocranium. The…
Safety of intra-articular hip injection of hyaluronic acid products by ultrasound guidance: an open study from ANTIAGE register.
2013
Abstract. – OBJECTIVE: We developed a standardized technique for ultrasound guided intra-articular injection of the hip joint with the purpose of extending routine intra-articular injection of hyaluronans and steroids to the hip, as commonly used in the knee. In this article we report the safety of this technique in an extended series of patients. PATIENTS AND METHODS: Patients were injected supine with an anterosuperior approach under ultrasound guidance. The Us probe is applied with a target device for biopsy. RESULTS: The standardised technique was used to inject 1906 patients with 4002 injections of hyaluronan products over a four-year period. The treatment was well tolerated with few, …
Significant interaction between high-dose methotrexate and high-dose piperacillin-tazobactam causing reversible neurotoxicity and renal failure in an…
2020
Introduction Pharmacokinetic interaction of high-dose methotrexate (MTX) and other concomitantly administered renally secreted medicinal products may lead to insufficient methotrexate serum level decrease and significant MTX toxicity. Case report We report the case of an 18-year-old male patient treated with high-dose MTX for an osteosarcoma and with high-dose piperacillin-tazobactam at the same time. MTX serum levels were severely elevated 24 hours after the MTX infusion and did not decrease in accordance with the specific calcium folinate rescue protocol. The patient experienced renal failure accompanied by neurological symptoms, most consistent with MTX-related renal and CNS toxicity. Ma…
COX-2 expression in chondrosarcoma: A role for celecoxib treatment?
2010
Chondrosarcomas are resistant to conventional chemo- and radiotherapy. A subset of chondrosarcomas arises secondarily in the benign tumour syndromes enchondromatosis (EC) and multiple osteochondromas (MO), and prevention of tumour development would greatly improve prognosis. We therefore investigated the effect of selective COX-2 inhibition on chondrosarcoma growth. COX-2 expression was studied in central- and peripheral cartilaginous tumours. The effect of COX-2 inhibition was assessed in four high-grade chondrosarcoma cell lines using celecoxib and NS-398 treatment. COX-2 activity (prostaglandin E-2 (PGE(2)) ELISA) and cell viability were measured. The (prophylactic) effect of celecoxib o…
Chondrodysplasia punctata, tibia-metacarpal (MT) type.
1990
We describe 7 patients with a new form of chondrodysplasia punctata. Its principal clinical manifestations are flat midface and nose, short limbs, and otherwise normal development. Consistent radiologic manifestations in the newborn infant are discrete calcific stippling, coronal clefts of vertebral bodies, short tibiae, and shortness of the 2nd and 3rd metacarpal bones. Radiologic findings in the older child include shortness of tibiae and the 3rd and 4th metacarpals.
Stippled epiphyses in fetal alcohol syndrome.
1990
We report on punctate epiphyseal calcifications (stippled epiphyses) in the fetal alcohol syndrome and present the differential diagnosis of chondrodysplasia punctata. A literature survey shows that epiphyseal calcifications accompanying alcoholic embryopathy are regularly located in the lower limbs and rarely found in the upper extremities.
Case series of fluoroscopic findings and 3D reconstruction of human spinal MRIs of the space of Okada.
2020
Objective To better understand the unexpected spread of contrast medium observed by conventional fluoroscopic X-ray images during standard neuraxial techniques used in the treatment of pain. The support of 3D reconstruction of MRI images of structures within the lumbar spine was used to better understand the space of Okada. Methods Lumbar facet joint and epidural corticosteroid injections in five patients under fluoroscopic guidance with loss of resistance to air or saline to identify the facet joints or epidural space. Next, in a retrospective study, the authors examined the retrodural space of Okada and the neighboring tissues with 3D reconstruction of spinal MRIs of seven patients withou…

Modulation of type II collagen-induced arthritis in DBA/1 mice by intravenous application of a peptide from the C1q-A chain.
1992
In this report we are able to show that intravenous (i.v.) application (day 0) of a nonapeptide (residues 26-34) from the human C1q A-chain (designated peptide A-C1q) prior to intradermal (i.d.) administration of chicken type II collagen (CII) in arthritis-susceptible DBA/1 mice (H2q), leads to abrogation of polymorphonuclear neutrophil (PMN) invasion into the joints. This nonapeptide exhibits epitope characteristics and high homology to residues 137-147 of CB11 (a cyanogen bromide fragment of chicken CII, known to contain both arthritis inducing and suppressing determinants). Arthritis index was lowest in animals pretreated i.v. with CII (as internal control), though animals pretreated i.v…
