Incidence, associated factors and clinical impact of severe infections in a large, multicentric cohort of patients with systemic lupus erythematosus.

Objectives: To estimate the incidence of severe infection and investigate the associated factors and clinical impact in a large systemic lupus erythematosus (SLE) retrospective cohort.

Methods: All patients in the Spanish Rheumatology Society Lupus Registry (RELESSER) who meet ≥4 ACR-97 SLE criteria were retrospectively investigated for severe infections. Patients with and without infections were compared in terms of SLE severity, damage, comorbidities, and demographic characteristics.

Radiologic findings of segmental testicular infarction.

Objective: Our objective was to describe the radiologic findings of segmental testicular infarction and to establish a proper diagnosis that can avoid orchiectomy.

Conclusion: The presence of a triangular-shaped avascular intratesticular lesion on sonography or MRI and enhancement of the surrounding borders on enhanced MR images may suggest a presurgical diagnosis of segmental testicular infarction and therefore avoid a total orchiectomy in these patients.

Closed lock (MRI fixed disc): a comparison of arthrocentesis and arthroscopy.

Twenty-six patients with a sudden-onset of persistent limited mouth opening and with MRI signs of articular discs fixed to the glenoid fossa were studied. After unsuccessful non-surgical treatment, arthroscopy with sodium hyaluronate infusion was performed in 16 joints. Follow-up ranged from 24 to 60 months (mean: 30.

Prognostic significance of DNA ploidy and proliferative index (MIB-1 index) in childhood rhabdomyosarcoma.

The prognostic value of DNA ploidy and proliferative index (PI) are well established in many cancers, but their significance in childhood rhabdomyosarcoma (RMS) is unclear. We studied the DNA content and PI of 45 cases of childhood RMS obtained retrospectively. DNA histograms were hyperdiploid in 30 cases (67%), diploid in 6 (13%), tetraploid in 5 (11%), polyploid in 3 (7%), and nonclassifiable in 1 (2%).

Use of botulinum toxin-A for musculoskeletal pain in patients with whiplash associated disorders [ISRCTN68653575].

Background: Whiplash associated disorder is commonly linked to motor vehicle accidents and sports injuries. Cervical injury is attributed to rapid extension followed by neck flexion. The exact pathophysiology of whiplash is uncertain but probably involves some degree of aberrant muscle spasms and may produce a wide range of symptoms.

Ovarian maldescent.

Undescended ovary is a rare disorder that can be associated with müllerian malformations. There is an unclear association with infertility and malignant disease. When an ovary is not in its normal location, it is sought in other locations above the pelvic brim.

Renal smooth muscle tumor with features of lymphangioleiomyomatosis. Problems in histological diagnosis.

A 44-year-old woman with left kidney tumor involving the perirenal and retroperitoneal lymph nodes is presented. Imaging findings including ultrasonography and computerized tomography showed renal and para-aortic masses and no features of lymphangioleiomyomatosis or angiomyolipoma were seen. The histopathological examination was considered as a renal smooth muscle tumor with features of lymphangioleiomyomatosis.

Chromosomal translocation 3;22 in an infertile man.

Objective: To present the first case of an infertile male with a normal phenotype and chromosomal translocation 3;22.

Design: Case report.

Setting: POVISA Medical Center.

Surgical treatment of recurrent mandibular dislocation by augmentation of the articular eminence with cranial bone.

Purpose: This article describes the use of calvarial bone grafts to augment the height of the articular eminence to treat recurrent mandibular dislocation.

Patients And Methods: Eight patients with mandibular recurrent dislocation were studied clinically, radiographically, and with magnetic resonance imaging (MRI) immediately before surgery, and at 1 week, 6 months, and 1 year after the operation. All the patients were treated with a modification of the Lindemann-Norman technique, performing an oblique osteotomy in the articular eminence and placing a calvarial graft into the osteotomy to augment the height of the eminence.
