Traumatic separation of the symphysis pubis during pregnancy: a case report

Diagnosis for etiology of public and lower back pain following trauma in a 37-year-old woman in an advanced stage of pregnancy. Physical examination and plain anterioposterior X-rays. Extensive traumatic separation of the symphysis pubis might result from a very forceful descent of the fetal head against the pelvic ring upon the mother's accidental falling. Propitious timing of a caesarian section permits the option of open reduction and internal fixation.

Severe osteoarthritis was demonstrated on physical examination, serial radiographs and magnetic resonance imaging. Only four cases of chondrolysis in solid organ recipients have been described in the literature.

Agmatine, decarboxylated arginine, was shown in preclinical studies to exert efficacious neuroprotection by interacting with multiple molecular targets. This study was designed to ascertain safety and efficacy of dietary agmatine sulfate in herniated lumbar disc-associated radiculopathy.

Osteoporosis and increased bone fractures in cerebrotendinous xanthomatosis

In three CTX patients, bone biopsies confirmed osteoporosis. Nine patients also sustained bone fractures following minimal trauma. Serum 25-hydroxyvitamin D ([25-OHD] 14.6 +/- 6.6 ng/mL v [normal] 30.4 +/- 8.0 ng/mL; P < .001) and 24,25-dihydroxyvitamin D ([24,25(OH)2D] 1.2 +/- 0.4 ng/mL v [normal] 2.7 +/- 0.8 ng/mL; P < .001) levels were low. Serum concentrations of 1,25(OH)2D, calcium, inorganic phosphorus, alkaline phosphatase, parathyroid hormone, and calcitonin were normal. Patients showed classic manifestations of CTX, including dementia, pyramidal and cerebellar insufficiency, peripheral neuropathy, cataracts, and tendon xanthomas associated with elevated serum cholestanol concentrations. These results demonstrate that extensive osteoporosis and increased risk of bone fractures are components of this inherited disease.

Standard treatment of GCT is comprised of local resection followed by local adjuvant therapy. Unicondylar osteoarticular resection is usually followed by a reconstructive procedure to restore the biomechanical demands of the joint. The present report describes a patient with satisfactory knee stability and functional outcome 32 years following medial femoral condyle resection with no reconstructive arthroplasty.

Eight hundred and sixty-six patients after whiplash injury were followed up on average 32 months post-trauma. All patients had clinical examination and radiographs performed on the day of the accident and at follow up. MRI, CT scan, bone scan, electromyographic (EMG) tests were performed upon request of the treating physician and correlated by the authors with the clinical findings. Cervical pain was the most common complaint (96%). Radiating pain to one side of the upper limbs or the shoulder was also very common (36 and 24%, respectively). Chin to chest test was found to be a strong indicator in differentiating between the less severe (grades 1 and 2) to more severe (grades 3 and 4) WAD patients. In 10% of the patients with normal radiographic findings, degenerative changes were found at follow up. CT scan and MRI did not add to patient diagnosis, except for those patients suffering from degenerative changes and decreased range of motion (RoM). Based on our findings the initial radiograph taken in the emergency room was the best imaging modality and probably the only one needed routinely following whiplash injury. Although this is a special subgroup of patient seeking compensation, the overall prognosis is favorable in all grades of WAD injury and there is no need for further diagnostic expenditures.

Carpal Canal Stenosis in Men With Idiopathic Carpal Tunnel Syndrome

Clinical Orthopaedics and Related Research, 1992

When compared with the controls, there was significant stenosis of the proximal part but not of the distal part of the carpal canal. Carpal canal stenosis is an important etiologic factor in the development of idiopathic carpal tunnel syndrome in males.

Materials and methods We carried out a retrospective review of 330 patients seeking compensation after rear-end car collisions. The treating physician referred all patients for EMG studies in the post-injury follow-up period and for additional CT scans and MRIs. All patients underwent physical and X-ray examination by the senior author (SD), and 75 patients with persistent radicular complaints were referred again for EMG studies. The results of the association between patient complaints, clinical examination, and EMG, CT and MRI studies are reported. Results We sought but failed to find any correlations between 354 EMG results with those of 278 CT scans and 75 MRIs. Both subjective complaints and early vs late EMG abnormalities showed statistical agreement and persistency of findings only at disc level C7/D1. Conclusions Our data indicate that follow-up EMG studies for patients with WAD do not contribute any useful information for patient management.

Meralgia paresthetica: A retrospective analysis of 79 patients evaluated and treated according to a standard algorithm

We retrospectively evaluated the management of spontaneous MP (i.e. MP not secondary to trauma or surgery) according to a standard algorithm. Initial management included oral medications, rest, and reduction of aggravating factors. Non-responders underwent a diagnostic local anesthetic nerve block test. Patients who responded with transient symptomatic relief were treated by local infiltration of corticosteroids. Surgical intervention was reserved for patients with positive nerve block test, who did not respond to nonoperative measures. A negative nerve block test ruled out the diagnosis of MP in 6/86 patients. Of 79 patients with MP, 21 responded to the initial nonoperative treatment and 48 patients responded to local corticosteroids. 3 of the remaining 10 patients underwent surgery (nerve transection 2, neurolysis 1). During an average of 3 (1-13) years of follow-up, symptoms consistent with MP did not recur in any of the 72 patients in whom symptoms had resolved after treatment. The algorithm used proved to be useful in the management of spontaneous meralgia paresthetica.
