Differences in impulse distribution in patients with plantar fasciitis.

The impulse distribution based upon vertical foot-floor reaction forces and time under the fore-, mid-, and hindfoot was determined using Tekscan's F-Scan system. This was compared in 40 barefoot patients with long-standing plantar fasciitis with an equal number of normal subjects. The patient group tended to load the hind- and midfoot to a lesser extent than the control group. Consequently, a greater proportionate load was borne by the forefoot. This result was highly significant for both the midfoot (P < 0.001) and forefoot (P = 0.002) comparisons. An objective biomechanical method such as this may be useful as a diagnostic aid, to identify individuals predisposed to this condition, and for evaluating the efficacy of various treatment modalities.

An audit of early hospital readmission after primary knee joint replacement.

BACKGROUND: Hospital readmissions following arthroplasty represent a considerable burden to the community. The present study investigates the magnitude of this problem and the reasons for early readmission. METHODS: The medical records of patients who underwent primary knee joint replacements between July 1989 and December 1994 were reviewed retrospectively. Readmission within 12 months of surgery was noted and the prognosis of these patients assessed. RESULTS: A total of 160 patients (180 arthroplasties) were appropriate for review. The readmission rate for knee-related morbidity was 18%. The main reasons for this included pain, stiffness, and the investigation/management of an inflamed joint. Notably, patellofemoral disease was common, particularly in the group without resurfaced patellae, manipulation of a stiff joint was rarely effective unless instituted early and aetiologies aside from sepsis often resulted in the patient returning with an inflamed joint. CONCLUSIONS: Readmission is a significant problem which heralds a poor 12-month prognosis.

Morphometric analysis of the right gastroepiploic artery and the internal mammary artery.

BACKGROUND: The internal mammary artery (IMA) and the right gastroepiploic artery (RGEA) are frequently used as conduits for coronary artery bypass grafting. METHODS: Morphometric measurements and histologic characteristics of the RGEA and the IMA were studied in 25 patients undergoing coronary artery bypass grafting. RESULTS: External radius was found to be more in the IMA (range, 18 to 56 microns; mean, 39.56 microns) in comparison with the RGEA (range, 24 to 51 microns; mean, 32.52 microns; p < 0.01). There was no significant difference between the vessels in intimal thickness (IMA: 0.0 to 0.25 micron; mean, 0.05 micron; RGEA: 0.0 to 0.28 micron; mean, 0.09 micron), internal radius (IMA: 5 to 47 microns; mean, 28.40 microns; RGEA: 16 to 42 microns; mean, 23.56 microns), area of media (IMA: 1,690 to 3,476 microns2; mean, 2,777.52 microns2; RGEA: 1,659 to 3,600; mean, 3,012.44 microns2), intimal thickening index (IMA: 0.0 to 0.02; mean, 0.01; RGEA: 0.0 to 0.13; mean, 0.01), and medial index (IMA: 0.14 to 0.60; mean, 0.36; RGEA: 0.18 to 0.63; mean, 0.39). Histologic examination of the RGEA showed more defects in continuity of internal elastic lamina and rich smooth muscle cells in the media. CONCLUSIONS: There was no difference in the morphometric measurements of the IMA and the RGEA except external radius, which was greater for the IMA. The histologic differences found in the RGEA may indicate an increased propensity for atherosclerosis of the RGEA as compared with the IMA. Some concern regarding the long-term patency of the RGEA in myocardial revascularization is warranted.

Papillary fibroelastoma of the mitral valve associated with rheumatic mitral stenosis.

Papillary fibroelastoma of the mitral valve diagnosed and treated in life is extremely rare. There have been eight cases documented so far. We report the first case of a mitral valve papillary fibroelastoma associated with severe rheumatic mitral stenosis and tricuspid regurgitation with stenosis. The tumor arose from the posteromedial papillary muscle of the mitral valve. The mitral valve was replaced after excising the valve with the tumor and the tricuspid valve was repaired. The patient did well and remains asymptomatic.

Geographical variations in the presentation of ruptured aneurysms of sinuses of valsalva: evaluation of surgical repair.

From 1981 to 1992, 13 male and 7 female patients underwent surgical correction for ruptured aneurysms of sinus of valsalva. A total surgical experience of 22 procedures including 2 reoperations is presented, accounting for 1.37% of open heart surgery for congenital heart disease at PGIMER Chandigarh. Ninety percent were in the 20- to 40-year age group. Forty-five percent of patients had symptoms of > 1-year duration (range 2 months to 20 years) and catastrophic onset of symptoms was noted in four (18%). All patients had localized aneurysms originating either in right coronary sinus (14 pts) or noncoronary sinus (8 pts). Sites of origin and rupture are detailed. Associated congenital abnormalities such as ventricular septal defect (VSD) (13 pts), aortic regurgitation (3 pts), and left superior vena cava and atrial septal defect (ASD) (1 pt each) were noted. The data pertaining to Oriental and Western groups of patients were analyzed, and the differences in age, mode of presentation, site of origin, rupture, and the spectrum of associated abnormalities were elucidated. The majority of the patients (86.4%) were operated by the Bicameral approach. Repair was tailored according to the extent and severity of the defect in the sinus of Valsalva and aortic valve annulus and also the presence and site of VSD.

Homograft aortic root replacement for destructive prosthetic endocarditis.

Prosthetic aortic valve endocarditis with extensive destruction of the aortic root, annular abscess formation, and left ventriculoaortic discontinuity was seen in 3 patients, with aorta to left atrial fistula formation in 2. Homograft aortic root replacement with use of the anterior mitral leaflet of the aortic root to repair the fistula was used successfully in all 3 patients. Their case reports are discussed to highlight the use of the homograft aortic root in these complicated cases, and to report the occurrence of aorto-left atrial fistula in prosthetic valve endocarditis.
