1/681. Atlantoaxial rotary subluxation in children.Traumatic torticollis is an uncommon complaint in the emergency department (ED). One important cause in children is atlantoaxial rotary subluxation. Most children present with pain, torticollis ("cock-robin" position), and diminished range of motion. The onset is spontaneous and usually occurs following minor trauma. A thorough history and physical examination will eliminate the various causes of torticollis. Radiographic evaluation will demonstrate persistent asymmetry of the odontoid in its relationship to the atlas. Computed tomography, especially a dynamic study, may be needed to verify the subluxation. Treatment varies with severity and duration of the abnormality. For minor and acute cases, a soft cervical collar, rest, and analgesics may be sufficient. For more severe cases, the child may be placed on head halter traction, and for long-standing cases, halo traction or even surgical interventions may be indicated. We describe two patients with atlantoaxial rotary subluxation, who presented with torticollis, to illustrate recognition and management in the ED.- - - - - - - - - - ranking = 1keywords = relation (Clic here for more details about this article) |
2/681. prognosis of acute poststreptococcal glomerulonephritis in childhood: prospective study and review of the literature.Serial, clinical, clinicopathologic and histologic studies performed simultaneously following onset of PS-AGN in children for a period of up to 144 months revealed no evidence of progression to chronic glomerulonephritis. Although acute morphologic changes were more severe in renal tissue obtained from patients with AGN following streptococcal upper respiratory infection than following pyoderma, the acute manifestations in both groups subsided 6 to 12 weeks after onset. Cumulative morphologic healing occurred in 20% of patients at 24 months, in 43% at 48 months after onset of PS-AGN; 1 patient who was unhealed at 49 months was lost to follow-up. In 2 patients (6%), acute histologic exacerbations without clinical signs occurred within 24 months after onset. Subsequent healing was documented histologically. Addis counts remained abnormal in a high percentage of patients throughout the 12 years of observation and did not correlate with the histologic findings of renal biopsy tissue. The occasional demonstration of renal vascular disease and/or hypertension may merely reflect the early development of spontaneous essential hypertension although the possibility of a relationship to the previous attack of PS-AGN is intriguing. This question cannot be answered at this time. Renal biopsy studies are more dependable than Addis counts in assessing the course of PS-AGN. The significance of persistence of immunofluorescent and/or electron microscopic changes (subepithelial dense deposits) many years after onset in 58% of 12 patients studied, at a time when a majority of patients (84%) revealed healing by light microscopy, remains to be assessed.- - - - - - - - - - ranking = 1keywords = relation (Clic here for more details about this article) |
3/681. Acute corneal necrosis after excimer laser keratectomy for hyperopia.OBJECTIVE: To describe a new, rare clinical complication after routine excimer laser photorefractive keratectomy to correct hyperopia. DESIGN: Case report with clinicopathologic correlation. MAIN OUTCOME MEASURES: Four weeks after treatment with excimer laser, a perforating keratoplasty was performed for persistent corneal opacities. The corneal button was examined using light and electron microscopy. Special immunohistochemical stains were used to detect apoptosis. RESULTS: The patient developed corneal opacities, endothelial precipitates, and a fibrinous exudate in the anterior chamber after the laser treatment. The changes did not respond to therapy directed against bacteria, fungi, and acanthamoeba. All examinations and special stains were negative for micro-organisms. By light microscopy, an anterior zone of corneal necrosis was present with a moderate amount of acute inflammatory cells. At the interface between necrotic and viable corneal stroma, keratocytes with typical features of apoptosis were detected by immunohistochemistry and electron microscopy. CONCLUSION: This is the first full histopathologic report of a case of acute corneal necrosis with signs of apoptosis after excimer laser therapy of the cornea. Surgeons should be aware of this rare but potentially severe complication.- - - - - - - - - - ranking = 1keywords = relation (Clic here for more details about this article) |
4/681. Lacrimal gland abscess: two case reports.BACKGROUND: Bacterial dacryoadenitis is rare and suppuration leading to abscess formation within the lacrimal gland has been very rarely reported in the antibiotic era. methods: The medical records and investigation results, including computed tomography (CT), of two patients with lacrimal gland abscess were reviewed. RESULTS: Two cases of lacrimal gland abscess, one a 28-year-old male and the other a 64-year-old female, are described. Both demonstrated a characteristic low-density area within an enlarged lacrimal gland on CT. The first case had been treated with antibiotics and the abscess, when drained, was sterile. The second case settled spontaneously. Neither patient suffered any sequelae of dry eye. CONCLUSIONS: Although rare, lacrimal gland abscess may still occur and may require surgical drainage if spontaneous resolution does not occur.- - - - - - - - - - ranking = 0.8375183373309keywords = record (Clic here for more details about this article) |
5/681. Clinical usefulness of conjugated bilirubin levels in patients with acute liver diseases.We used a specific method to measure conjugated bilirubin levels in patients with acute liver diseases to examine its clinical usefulness. Conjugated and total bilirubin levels were measured in 102 samples obtained from six patients with acute liver diseases (three with fulminant hepatic failure, one with acute severe hepatitis and two with acute hepatitis; see text for criteria). Total and conjugated bilirubin levels were measured with Iatro T (total)-Bil and D (direct)-Bil kits (Iatron laboratories tokyo, japan) and with conventional Nescauto T(total)-Bil and D(direct)-Bil VE kits (Nippor Shoji, Osaka, japan). The Iatro D-Bil kit measures conjugated bilirubin correctly, while the Nescauto D-Bil VE kit measures some nonconjugated bilirubin and delta bilirubin as well as conjugated bilirubin. Total bilirubin levels determined by the two methods showed good correlation. The conjugated bilirubin level measured with the Iatro D-Bil kit was strongly correlated with the direct bilirubin level measured with the Nescauto D-Bil VE kit, but there was no correlation between the conjugated-to-total bilirubin ratio and the direct-to-total bilirubin ratio. When we examined the changes in bilirubin levels in our patients with respect to outcome, we found that the two patients in whom the ratio of conjugated-to-total bilirubin exceeded 0.3 died, while all four patients in whom the ratio remained below 0.3 survived. The ratio of direct-to-total bilirubin was unrelated to outcome. The conjugated bilirubin level measured with the Iatro kits was therefore considered useful for the diagnosis and follow-up of acute liver diseases.- - - - - - - - - - ranking = 2keywords = relation (Clic here for more details about this article) |
6/681. Acute pulmonary edema associated with placement of waist-high, custom-fit compression stockings.Compression stockings are a safe, noninvasive treatment for patients with symptomatic orthostatic hypotension due to autonomic nervous system dysfunction. In this report, we describe a 75-year-old man who had development of pulmonary edema approximately 45 minutes after placement of compression stockings on the first postoperative day following a carotid endarterectomy. No sudden changes were noted on an electrocardiogram or echocardiogram or in the cardiac isoenzymes associated with the pulmonary edema. The patient had a history of coronary artery disease, diabetes mellitus-induced autonomic nervous system dysfunction, and recent surgery near the carotid baroreceptor. All these factors may have limited his ability to compensate for a rapid increase in central blood volume. The temporal relationship of the patient's respiratory distress to the placement of the compression stockings, in the absence of laboratory findings of primary cardiac dysfunction, make stocking-related fluid shift the likely precipitating event in the formation of acute pulmonary edema. This case suggests that compression stockings should be used with caution in patients with limited cardiac reserve.- - - - - - - - - - ranking = 1keywords = relation (Clic here for more details about this article) |
7/681. Posterior circulation aneurysms. Technical strategies based on angiographic anatomical findings and the results of 60 recent consecutive cases.Ninety-eight patients with aneurysms of the posterior circulation were admitted to our department from 1993 to 1997. Sixty of them underwent microsurgical treatment, mostly in the acute stage of subarachnoid hemorrhage. Peri- and intraoperative management were carried out according to a structured treatment strategy. Special aspects of surgical technique included extradural selective anterior clinoidectomy for basilar head aneurysms, lateral suboccipital craniotomy and partial condylectomy without laminectomy for aneurysms of the vertebral artery or posterior inferior cerebellar artery, and a trans-Sylvian approach, as used in selective amygdalohippocampectomy, for aneurysms of the posterior cerebral artery. A careful angiographic evaluation of the aneurysms in relation to the neighboring important arteries and bony structures was essential for optimal surgical planning. Forty-nine patients (82%) made a good recovery by 3 months after surgery. The mortality was 7%.- - - - - - - - - - ranking = 1keywords = relation (Clic here for more details about this article) |
8/681. A case of SLE with acute, subacute and chronic cutaneous lesions successfully treated with dapsone.We describe a patient with systemic lupus erythematosus (SLE) who exhibited severe cutaneous involvement characterized by the simultaneous presence of acute, subacute and discoid lesions in association with anti-S1 antibodies. After she failed to respond to chloroquine, medium to low dose steroids, steroid pulses, retinoids and cyclophosphamide, the patient was treated with dapsone and a dramatic improvement in the cutaneous lesions was seen after only one month.- - - - - - - - - - ranking = 0.27253986403435keywords = bite (Clic here for more details about this article) |
9/681. 'Dysphagia Severity Score' system: clinical outcomes in paediatric dysphagia.Clinical evaluation and analysis of therapeutic intervention, by means of a user-friendly outcome measure system, is essential in the management of a paediatric dysphagia caseload. The objective of this study was to design a Dysphagia Severity Score (DSS) system and to evaluate its usefulness in profiling dysphagia outcomes. Clinical outcome data, based on ten clinical parameters describing dysphagic status pre- and post-intervention, were collated for 23 concurrent cases and recorded on a data base. Results indicate that all subjects scored an improvement in DSS percentage post-intervention, with an average improvement of 21%. Dysphagia Severity Score profiles are presented for two patients and the limitations and applications are discussed.- - - - - - - - - - ranking = 0.8375183373309keywords = record (Clic here for more details about this article) |
10/681. Transitions to independent living after ABI.One of the most challenging questions facing service providers and policy makers alike is the appropriate level of supervision for adults living in the community following a brain injury. In a 3-year province-wide study of people entering the community following brain injury rehabilitation, four individuals (out of 22 studied) made a transition from fully supervised living to lower levels of formal supervision during their first year in the community. The present study seeks to provide more information about these four individuals, the factors that allowed them to move to lower levels of supervision, and the perceived success of that transition. For each participant, the interviews conducted over the 1 year period in the initial study were reviewed in detail for information about independent living. In addition, each participant was interviewed again for this study, along with his significant other and three of the community programme staff who were most closely involved with his transition. To summarize, factors most salient in the success of transition included: (1) Roles and relationships of family and programme personnel; (2) staying away from drugs and alcohol; (3) availability of structured daily activities, including productive activity or community programme; (4) financial management; and (5) emotion and behaviour self-control. Secondary themes related to successful community living also included the availability of transportation and prior experience with community living since the onset of brain injury. These results offer the experience of four individuals in moving towards independent living. As such, they provide a starting point for further discussions of the process of supporting individuals to pursue the ultimate goal of independent living.- - - - - - - - - - ranking = 1keywords = relation (Clic here for more details about this article) |
