1/260. Chronic compartment syndrome affecting the lower limb: MIBI perfusion imaging as an alternative to pressure monitoring: two case reports.Intracompartmental pressure monitoring remains the primary method of diagnosing chronic compartment syndrome. MIBI perfusion imaging is widely available and offers a radionuclear imaging technique for diagnosing this condition. Although the results are not identical with those from pressure monitoring, MIBI may offer a useful screening test for this condition.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/260. The fourth-compartment syndrome: its anatomical basis and clinical cases.We propose a new term, the "fourth-compartment syndrome" to describe chronic dorsal wrist pain of the fourth compartment. Five main causes responsible for this syndrome are thought to be as follows: 1. Ganglion involvement, including an occult ganglion; 2. Extensor digitorum brevis manus muscle; 3. Abnormal extensor indicis muscle; 4. Tenosynovialitis; 5. Anomaly or deformity of carpal bones. Should the above mentioned conditions occur in the fourth compartment, pressure within the fourth compartment increases, ultimately compressing the posterior interosseous nerve directly or indirectly. Anatomical studies of the fourth compartment of the wrist and the posterior interosseous nerve are presented and the fourth-compartment syndrome is summarized with twelve clinical cases (six cases of occult ganglions, two cases of extensor digitorum brevis manus, two cases of tenosynovialitis, one case of abnormal extensor indicis muscle, and one case of carpal bossing).- - - - - - - - - - ranking = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
3/260. Treatment of a large congenital coronary fistula with coil embolization.A 77-year-old woman suffering from progressive dyspnea and chest pain for 2 1/2 years was admitted to hospital. There were no ECG changes at exercise test and a dobutamine stress echocardiography was normal. At catheterization, right-sided pressures were within normal limits. coronary angiography revealed a congenital coronary fistula, 3-4 mm in diameter, from the left anterior descending artery to the proximal pulmonary artery. There was no significant rise in blood oxygen saturation in the pulmonary artery. Transcatheter coil embolization was performed in the distal part of the tortuous fistula. Flow ceased within minutes, demonstrating the feasibility and efficacy of this technique for treating large fistulas.- - - - - - - - - - ranking = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
4/260. A GLC1A gene Gln368Stop mutation in a patient with normal-tension open-angle glaucoma.PURPOSE: To present a case involving a patient with normal-tension glaucoma with a Gln368Stop mutation of the myocilin/trabecular meshwork inducible glucocorticoid response protein (MYOC/TIGR) gene. methods: Slit-lamp biomicroscopic and gonioscopic examination, morphometry of the optic disc, 24-hour intraocular pressure (IOP) profile, and perimetry were performed to determine the phenotype of the patient. neurologic examination and a computed tomographic (CT) scan of the brain were performed to rule out a neurologic disorder. Single-strand confirmation polymorphism (SSCP) analysis and subsequent sequence analysis of blood was performed for genotyping of the GLC1A gene. RESULTS: A nonsense codon, namely a Gln368Stop mutation in the third exon of the GLC1A gene, was found in this patient with normal-tension glaucoma. CONCLUSION: In contrast to previous reports, a Gln368Stop mutation of the GLC1A gene need not be confined to patients with glaucomatous optic atrophy due to high IOP. The pathogenesis of glaucoma associated with GLC1A gene mutations might be more complex than expected, and (unknown) suppressor mechanisms have to be considered.- - - - - - - - - - ranking = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
5/260. skin care of the pediatric patient.Several factors influence the chronically ill child's susceptibility for skin breakdown. nurses are an integral part of the care team that has the responsibility for identification of these factors, as well as pressure ulcer prevention and early intervention. An important aspect of this responsibility is identification of individuals at risk. This article provides a guide for assessment and early intervention for skin breakdown in chronically ill children. A care plan and consultation recommendations are included.- - - - - - - - - - ranking = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
6/260. Chronic compartment syndrome of the lower leg: a new diagnostic method using near-infrared spectroscopy and a new technique of endoscopic fasciotomy.A 19-year-old female basketball player had chronic compartment syndrome. During basketball playing, she complained of bilateral lower leg pain that disappeared after several minutes of rest. The intracompartmental pressure in the anterior compartment was 41 mm Hg on the right side and 29 mm Hg on the left side immediately after playing. Prolonged ischemia of the anterior compartment was observed in comparison with four normal controls using near-infrared spectroscopy. magnetic resonance imaging also revealed that the anterior compartment was mainly affected. Endoscopic fasciotomy was performed using an arthroscope, a transparent outer tube, and a retrograde blade. After the operation, her symptoms disappeared. Three months postoperatively, the anterior compartment pressure decreased and prolonged tissue ischemia improved. Endoscopic fasciotomy allowed us to cut the fascia safely and less invasively. We concluded that this technique is useful in treating chronic compartment syndrome in the anterior compartment of the lower leg.- - - - - - - - - - ranking = 0.33333333333333keywords = pressure (Clic here for more details about this article) |
7/260. Change in optic disc topography associated with diurnal variation in intraocular pressure.PURPOSE: A case demonstrating significant changes in optic disc topography from variation in intraocular pressure (IOP) is demonstrated. methods: Within a single 24-hour period, confocal scanning laser ophthalmoscopic images were obtained in the left eye of a patient during an IOP peak (60 mmHg) and during an IOP trough (18 mmHg). RESULTS: During an IOP trough, paired t tests showed significant reduction in cup area, cup volume, mean cup depth, and maximum cup depth, and a significant increase in rim area and cup-to-disc (CD) ratio. CONCLUSION: Under certain conditions, optic disc topography may be affected by diurnal variations in IOP.- - - - - - - - - - ranking = 0.83333333333333keywords = pressure (Clic here for more details about this article) |
8/260. Improvement of pulmonary hypertension after liver transplantation.Pulmonary hypertension at the end stage of chronic liver disease is not an uncommon situation. This association termed portopulmonary hypertension raises the question of the feasibility of performing orthotopic liver transplantation (OLT). In the case reported herein, there was a favorable outcome after OLT, even though the mean pulmonary artery pressure (MPAP) before transplantation was increased to 45 mm Hg. Before OLT, the cardiac index (CI) was considerably elevated (7.69 L/min/m2), giving evidence of a marked hyperdynamic circulatory state. The CI decreased significantly after OLT (3.38 L/min/m2), and this produced a significant decrease in the MPAP. Our observation suggests that portopulmonary hypertension due to a marked increase in the CI can be managed successfully by OLT.- - - - - - - - - - ranking = 0.16666666666667keywords = pressure (Clic here for more details about this article) |
9/260. The location of chronic pregnancy hypertension on the vasoconstriction-volume spectrum: working hypothesis.OBJECTIVE: The purpose of this study was to examine whether volume loading is a factor in chronic pregnancy hypertension. STUDY DESIGN: Five patients with chronic hypertension performed home self-monitoring daily with a noninvasive pressure transducer from a fingertip. Determinants of mean arterial pressure were computed from the pressure data and a concurrent electrocardiogram. For this study blood pressure and rapid ejection time, which is an empiric indicator of arterial compliance, were evaluated during antihypertensive therapy. Data were transmitted by facsimile to the hospital. RESULTS: One patient with hypertension who was admitted to the study at 10 weeks' gestation became normotensive with a diuretic (furosemide) alone. Medication was discontinued at 23 weeks' gestation. This patient remained normotensive until delivery at 41 weeks' gestation. blood pressure was controlled with furosemide combined with nifedipine and labetolol in the other 4 cases. Three patients were studied with concurrent blood pressure and rapid ejection time measurements made before and after antihypertensive medication. All 3 showed decreases in these measurements with medication. CONCLUSION: Both volume excess and vasoconstriction should be considered in the pathogenesis of chronic pregnancy hypertension.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
