1/343. Eighteen fractures in a man with profound mental retardation.A 39-year-old man with generalized tonic clonic epilepsy and profound mental retardation sustained 18 fractures (15 in appendicular and 3 in axial bones) during 19 years. Both femoral necks were fractured, requiring surgical repair. Although he had been on antiepileptic drugs for 35 years, he had no radiographic or biochemical sign of osteomalacia. He had a very low bone mineral density, suggesting osteoporosis. This case illustrates an important medical problem affecting people with developmental disability and a management challenge for their caretakers.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
2/343. Femoral fracture at the proximal end of an intramedullary supracondylar nail: a case report.Retrograde intramedullary supracondylar nails have been added to the orthopedic armamentarium for treatment of distal femoral fractures. Major complications of this new technique have not been noted. We report a case of a femoral fracture at the proximal end of a retrograde intramedullary supracondylar nail. We hypothesize that this complication may be due to the proximal end of the nail acting as a stress riser, with the cortical holes drilled for the interlocking screws compounding this effect.- - - - - - - - - - ranking = 1keywords = fracture (Clic here for more details about this article) |
3/343. Clinical therapeutic conference: recurrent venous thrombotic and thromboembolic disease.Recurrent venous thrombotic and thromboembolic disease, once thought to be an uncommon entity, is increasingly being recognized. Etiologies of recurrent deep venous thrombosis usually include elements of Virchow's triad. Venous stasis (e.g., immobilization, congestive heart failure, acute myocardial infarction, obesity), hypercoagulability (e.g., malignancy, inflammatory bowel disease, hyperhomocysteinemia, protein c resistance, antithrombin iii, protein c or S deficiency) and endothelial trauma (e.g., surgical trauma, venous trauma, in-dwelling venous instrumentation) are risk factors. diagnosis is dependent on objective testing, including venography duplex Doppler (color) ultrasonography and impedance plethysmography. Treatment is usually started with heparin or low-molecular-weight heparin and advanced to warfarin (adjusted to international normalized ratio). Prophylaxis may continue using low-molecular-weight heparin, warfarin, venacaval interruption (Greenfield filter), or concomitant use of the platelet-active agent indobufen and graduated compression stockings.- - - - - - - - - - ranking = 0.086783586850781keywords = compression (Clic here for more details about this article) |
4/343. Unusual longitudinal stress fractures of the femoral diaphysis: report of five cases.We present five cases of a distinctive type of longitudinal stress fracture of the upper femoral shaft in which the fracture line is parallel to the outer surface of the bone, in contrast to the perpendicular orientation to the cortical surface in previously reported cases of diaphyseal stress fractures. In two cases the fracture recurred after 15 and 18 months, respectively.- - - - - - - - - - ranking = 1.3333333333333keywords = fracture (Clic here for more details about this article) |
5/343. ophthalmoplegic migraine and periodic migrainous neuralgia, migraine variants with ocular manifestations.The spectrum of migraine has been outlined with particular attention to two entities: ophthalmoplegic migraine and Periodic Migrainous neuralgia. Although quite different in many respects from classical migraine, the relationship of a periodic localized vascular phenomenon giving rise to headache and transient neurologic signs, classify PMN and OPGM as migraine variants. Supportive of this concept, the literature has been reviewed in both entities, and some observations are made on the validity of earlier reports. It is the author's opinion that Raeder's syndrome should be reserved for patients with a lesion localizing in the paratrigeminal area. This does not exclude migraine as an etiologic agent but also recognizes tumors, infections and fractures as being more common.- - - - - - - - - - ranking = 0.16666666666667keywords = fracture (Clic here for more details about this article) |
6/343. Rosai-Dorfman disease presenting as a pituitary tumour.A 45-year-old woman had pyrexia, headaches, collapse and hyponatraemia. Intracerebral abscess, bacterial meningitis and subarachnoid haemorrhage were excluded. She was given intravenous antibiotics and gradually recovered. One month later she was readmitted with diplopia, headache and vomiting. serum sodium was low (107 mmol/l) and a diagnosis of inappropriate ADH secretion was made. MRI scan showed a suprasellar tumour arising from the posterior pituitary gland. A skin rash gradually faded. serum cortisol, prolactin, gonadotrophins and thyroid hormone levels were low. A pituitary tumour was removed trans-sphenoidally, she had external pituitary radiotherapy, and replacement hydrocortisone and thyroxine. She was well for 12 months when she developed progressive weakness and numbness of both legs. Examination suggested spinal cord compression at the level of T2 where MRI scanning showed an intradural enhancing mass. This spinal tumour was removed and her neurological symptoms disappeared. Nine months after this she developed facial pain and nasal obstruction. CT scan showed tumour growth into the sphenoid sinus and nasal cavities. A right Cauldwell-Luc operation was done and residual tumour in the nasal passages was treated by fractionated external radiotherapy and prednisolone. Histological examination of the specimens from pituitary, spinal mass, and nasal sinuses showed Rosai-Dorfman disease, a rare entity characterized by histiocytic proliferation, emperipolesis (lymphophagocytosis) and lymphadenopathy. aged 48 she developed cranial diabetes insipidus. Although Rosai-Dorfman syndrome is rare, it is being reported with increasing frequency, and should be borne in mind as a possible cause of a pituitary tumour.- - - - - - - - - - ranking = 0.086783586850781keywords = compression (Clic here for more details about this article) |
7/343. Recurring fibro-obliterative venopathy in liver allografts.Recurrent diseases in liver allografts are not uncommon. These occur most frequently in those transplanted for viral hepatitis b and C. We report an unusual case of recurrent process in two consecutive liver allografts received by a 37-year-old woman, who previously had an unremarkable past medical history but developed a rapidly progressive cholestatic liver failure. Histopathologic examination of the native liver showed fibroocclusive lesions of both terminal hepatic venules and portal vein branches. The exuberant fibroobliterative process created dense fibrosis with whorled appearance, and broad fibrous septa connecting adjacent central areas, and sometimes bridging portal to central areas. Dense portal fibrosis resulted in compression atrophy and loss of bile ducts. The first allograft, which failed within 3 months, showed histopathologic findings similar to that of the native liver. A liver biopsy that was performed 20 months after the second liver transplant again showed similar histopathology. The histopathologic features and clinical presentation of this patient suggest an unusual form of recurring progressive fibroobliterative venopathy causing liver failure.- - - - - - - - - - ranking = 0.086783586850781keywords = compression (Clic here for more details about this article) |
8/343. Extradural balloon obliteration of the empty sella report of three cases (intrasellar balloon obliteration).empty sella syndrome is an anatomical and clinical entity composed of intrasellar reposition of the CSF and compression of the pituitary tissue, resulting in a clinical picture of headache, visual field defect, CSF rhinorrhea and some mild endocrinological disturbances. While some cases are primary with no appreciable aetiology, secondary cases are associated with prior operation or radiotherapy of the region. In our series, 3 patients with primary empty sella syndrome were treated by the current approach of extradural filling of the sellar cavity. This technique was first described by Guiot and widely accepted thereafter. We used a detachable silicon balloon filled with HEMA or liquid silicone for obliteration of the sellar cavity and obtained clinically satisfactory results without complications. Visual symptoms regressed and headache disappeared. But at long term follow-up all the balloons were found to be deflated. Despite the facility and efficacy of the technique we do not recommend it in the treatment of the empty sella because the filling of the sella is only transient and relapses may occur.- - - - - - - - - - ranking = 0.086783586850781keywords = compression (Clic here for more details about this article) |
9/343. Repeat syncopal attacks due to postsurgical right ventricular pseudoaneurysm.Pseudoaneurysm of the right ventricular outflow tract is a rare lesion caused by disruption of the ventricular wall that allows the blood to leak into the surrounding space. It often complicates surgery involving right ventriculotomy and progressively increases in size, therefore causing airway compression, pulmonary perfusion asymmetry, thromboembolism, and rupture. We report on a patient who developed right ventricular pseudoaneurysm early after surgery for atrio-ventricular septal defect with tetralogy of fallot and needed emergency surgical repair due to low cardiac output and repeat syncopal attacks.- - - - - - - - - - ranking = 0.086783586850781keywords = compression (Clic here for more details about this article) |
10/343. Use of the palmaris brevis flap for preventing recurrent median nerve compression in mucolipidosis.In a patient with severe, recurrent bilateral carpal tunnel syndrome secondary to mucolipidosis, the 'turnover' palmaris brevis flap was used in conjunction with internal neurolysis. The procedure was effective in alleviating symptoms of recurrent carpal tunnel compression in both hands.- - - - - - - - - - ranking = 0.43391793425391keywords = compression (Clic here for more details about this article) |
