Altered (oxidized) C1q induces a rheumatoid arthritis-like destructive and chronic inflammation in joint structures in arthritis-susceptible rats.

1997

Previous studies have identified an altered C1q molecule in synovial fluids from the joints of rheumatoid arthritis patients. We therefore immunized arthritis-susceptible Lewis 1A.AVN rats with either native C1q (C1q nat), altered (oxidized) C1q (C1q ox), or type II collagen (CII, induces arthritis in these animals), in order to induce arthritis. Unlike C1q nat, both CII and C1q ox were able to induce swelling and erythema of joints consistent with an arthritis-like inflammatory reaction. Histopathological evaluation of individual joint sections revealed synovitis, bursitis and tendovaginitis, massive joint destruction, and severe pannus formation. In a time-course study, no differences in …

Fertility in McCune Albright syndrome female: A case study focusing on AMH as a marker of ovarian dysfunction and a literature review.

2021

Abstract Background The molecular basis of McCune Albright syndrome (MAS) is a recurrent GNAS Postzygotic gain of function sporadic mutation, resulting in a mosaic disease. Most of girls present precocious puberty, caused by the development of recurrent ovarian cysts with autonomous Hyperestrogenic stimulation. After menarche, the majority of patients with ovarian GNAS mutation have menstrual disturbances and infertility. Objectives We wanted to focus on the fertility of MAS females and propose an appropriate management, by a detailed case report and an exhaustive review of the literature on fertility and pregnancy in MAS females. Results We present the case of a 29-year-old MAS female, who…

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…

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.

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…

The "critical zones" of entrapment of the nerves of the lower limb.

1991

The author has studied, in a group of 40 dissections on cadavers of individuals of different ages, the main “critical zones” of entrapment of some terminal branches of the lumbo-sacral plexus, which include canals (fibrous, osteo-fibrous, fibro-muscular), intervals (intermuscular, fibro-muscular, musculo-ligamentous), rings (fibrous or fibro-muscular) and foramina. They provide the topographical anatomical basis for possible compressive phenomena of the nerves of the lower limb.

Arthralgia as an early extraintestinal symptom of Whipple's disease. Report of five cases.

1997

Five patients with Whipple's disease all suffered from arthralgia for a long time (15 years in one case) before developing gastrointestinal or other symptoms. In all patients, arthralgia was seronegative, and there was no evidence of joint destruction. Arthralgias were symmetric and migrating. Whipple's disease is part of the differential diagnosis of enteropathic arthralgia. Thereby, the polymerase chain reaction can be a helpful tool to prove Whipple's disease in difficult differential diagnosis.

Anatomy of the Sacral Roots and the Pelvic Splanchnic Nerves in Women Using the LANN Technique

2007

AIMS: To report on our anatomic and electrophysiologic findings about the sacral nerve roots and the pelvic splanchnic nerves during laparoscopic pelvic surgery. METHODS: The pelvic splanchnic nerves and the sacral nerve roots were dissected in 336 consecutive patients undergoing laparoscopy for pelvic pain syndrome or gynecologic diseases. Intraoperative assessment of the functionality of the exposed nerves was performed using the LAparoscopic Neuro-Navigation (LANN) technique. RESULTS: Dissection of the sacral roots and the splanchnic pelvic nerves lateral to the sacral hypogastric fascia was feasible without any complications in all patients in this series. The mean surgical time was 16 …

2019

Background To compare the frictional resistance between passive self-ligating brackets and conventional brackets with low-friction ligature under bracket/archwire and root/bone interface during dental alignment and leveling. Material and methods A tridimensional model of the maxilla and teeth of a patient treated with conventional brackets, and slide ligatures was generated employing the SolidWorks modeling software. SmartClip self-ligating brackets and Logic Line conventional brackets were assembled with slide low-friction ligatures, utilizing archwires with different diameters and alloys used for the alignment and leveling stage. Friction caused during the bracket/archwire interface and s…
