The purpose of this study was to evaluate and assess the sporting and physical activities of patients who had undergone an Oxford medial unicompartmental knee arthroplasty (UKA). Seventy-six patients who underwent a UKA between 2000 and 2003 were reviewed. Demographic data such as age, sex and comorbidities were recorded. University of California Los Angeles (UCLA) activity level ratings and Oxford knee scores were determined for each patient. The sporting and physical activities of all patients' pre- and post-operatively were recorded. The mean age of patients was 64 years (range 49-81) at surgery and 66 years (range 53-82) at review. The mean follow up time was 18 months (range 4-46). Following surgery there was a significant improvement in UCLA activity level scores from 4.2 to 6.5 (Wilcoxon Matched-pairs Signed-rank Test, p<0.01). Forty-two patients (64%) regularly participated in sport before they became symptomatic with significant knee pain, and thirty-nine patients (59%) regularly participated in sports after surgery. In total 93% of patients successfully returned to their regular sporting and physical activities following surgery. The published long-term survivorship of the Oxford UKA has given surgeons increasing confidence to use the prosthesis on a younger generation of patients. Our study has demonstrated that this population of patients is extremely active. A more detailed study is required to evaluate the long-term effects of sporting activity on the Oxford UKA.
Ethanolic extract of Beta vulgaris roots given orally at doses of 1000, 2000 and 4000 mg/kg exhibited significant dose-dependent hepatoprotective activity against carbontetrachloride (CCl(4))-induced hepatotoxicity in rats. Hepatotoxicity and its prevention were assessed by serum markers viz. cholesterol, triglyceride, alanine amino transferase and alkaline phosphatase.
The incidence of osteoporotic fractures of the distal humerus is increasing, and the treatment of these injuries merits closer review. We assessed the results of 28 elderly patients (29 fractures) with a mean age of 85 years (range, 75-100 years). Open reduction and internal fixation was done on 21 elbows, and eight elbows were treated nonoperatively. Orthopaedic Trauma Association grading showed that the group treated with internal fixation had favorable results (three excellent, nine good, seven fair, and two poor) compared with the nonoperatively treated group (zero excellent, two good, three fair, and three poor). Mean loss of extension and mean flexion were better in the surgically treated patients (23.5 degrees and 99 degrees ) than in the nonoperatively treated patients (33.5 degrees and 71 degrees ). Substantial pain relief (mild or no pain) was achieved in a higher proportion (52%) in the surgically treated group than in the nonoperatively treated group (25%). Anatomic restoration of distal humeral tilt and articular congruity also were better in the surgically treated patients. Rates of complications were observed to be comparable to those described in the literature for younger patients. These findings reflect the relevance of surgical fixation of such fractures in this age group highlighting the need for additional clinical studies.
INTRODUCTION: Intra-articular fractures of the proximal interphalangeal joint are usually treated by one of many methods of external fixation, but this does not restore the articular surface. We describe a procedure where bone grafting and internal fixation are used to restore the articular surface. PATIENTS AND METHODS: A prospective study was conducted in which three patients underwent surgical treatment for this fracture. We describe a surgical procedure where bone graft harvested from the distal radius is packed through a diaphyseal window to restore the articular surface. This is followed by internal fixation with mini-screws. RESULTS: The average follow-up was 61 months. At last follow-up the average arc of movement of the proximal interphalangeal joint was 100 deg and the average Disability of the Arm, Shoulder and Hand (DASH) Score was 2. Postoperative radiographs showed restoration of the articular contour in all three patients. CONCLUSION: The surgical technique described addresses the issues of restoration of the articular surface and permits early mobilisation. The results for our group are excellent and compare favourably with those achieved using external fixators described in the literature.
We present three patients with large intraparenchymal isolated degenerating cysticerci in whom the diagnosis was primarily based on in-vivo proton MR spectroscopy, and subsequently confirmed histologically. We suggest that the presence of succinate alone or more succinate acetate indicates the presence of degenerating cysticerci and differentiates them from anaerobic brain abscesses, which show acetate alone or in higher concentration than succinate, even when the clinical and imaging features are similar.
BACKGROUND: Distal biceps tendon ruptures are uncommon injuries with only around 300 cases reported in the literature. Current management tends to favour anatomical reinsertion of the tendon into the radial tuberosity, especially in young and active individuals. These injuries are commonly repaired using either a single anterior incision with suture anchors or the Boyd-Anderson dual incision technique. CASE REPORT: We report the use of a bioabsorbable interference screw for the repair of distal biceps tendon rupture using a minimal incision technique. In this technique the avulsed tendon and a bioabsorbable screw are secured in a drill hole on the radial tuberosity using whip stitch and fibre wire sutures according to Biotenodesis system guidelines. CONCLUSION: The technique described requires minimal volar dissection that is associated with a reduced number of synostosis and posterior interosseous nerve injuries. The bioabsorbable interference screw has all the advantages of being biodegradable and has been shown to have greater pullout strength than suture anchors. It is also a reasonable alternative to titanium screws in terms of primary fixation strength. The strong fixation provided allows early active motion and return to previous activities as seen in our case.
We studied 29 patients with distal femoral fractures stabilised using the less invasive stabilisation system (LISS). Four patients were excluded from the final follow-up (three deaths and one case of quadriplegia). The mean age of the remaining 25 patients (9 males and 16 females) was 60.9 years and the mean follow-up 18 months (range 12-24 months). Eleven patients were tertiary referrals from other hospitals (seven cases were referred due to failure of primary fixation). Overall, there were 12 cases of high-energy trauma (7 open fractures). According to the AO classification, there were 5 Type 33A, 2 Type 33B and 12 Type 33C fractures and 4 Type 32A, 1 Type 32B, 1 Type 32C fractures. Functional assessment was performed using the modified Hospital for Special Surgery (HSS) and the Schatzker and Lambert scores. The average time to union in 22 cases was 3.5 months (range 2-5 months). All of the acute cases united without the need for bone grafting. There were three out of seven cases of non-union in the salvage group still undergoing treatment. The overall result in the acute cases was good and in the salvage cases fair. While this is a small series of patients, our preliminary data indicate favourable results using the LISS in stabilising acute distal femoral fractures. However, when the LISS is used as a revision tool the results seem to be less satisfactory. The system appears to be user-friendly and no technical difficulties were encountered.
We studied 32 consecutive patients with open distal tibial pilon fractures. All patients had radical debridement with immediate skeletal stabilisation and early soft-tissue cover with a vascularized muscle flap. The minimum follow-up was 1 (range 1-8) year. There were four superficial infections, two deep infections and two amputations. There were no long-term problems with union and no patient required an ankle fusion. Patients were assessed using the SF-36 questionnaire. There were significant differences from the US norm in physical function score ( p<0.01), role physical score ( p<0.05) and physical component score ( p<0.01). Physical component score of 38.5 was significantly better ( p<0.01) when compared with amputees from severe lower-extremity trauma. Our protocol for management resulted in a good functional outcome with low infection and amputation rates.
We studied the outcome of patients with chronic distal radioulnar joint symptoms who were treated with excision of the distal ulna and reconstruction using the flexor carpi ulnaris tendon. Twelve patients with 14 wrists were assessed. Ten patients were posttraumatic, and two had bilateral surgery for rheumatoid arthritis. Average age was 37 years at time of operation. Follow-up averaged 20 months (9 months to 4 years). All patients except one reported improvement in pain symptoms. Grip strength of the operated hand as measured by dynamometer readings was 67% of the strength of the normal hand with five wrists achieving an excellent result in grip strength. Eleven patients reported a subjective improvement in functional activities. An improved range of motion was obtained in all patients. We discuss the importance and basis for ligamentous reconstruction following excision of the distal ulna and review the literature for other previously described procedures.
We describe a very cheap, simple and effective dynamic external fixator for treatment of pilon fractures of the proximal interphalangeal joint. At final follow-up, nine such fractures had regained an average range of motion of 79 degrees (range, 65-90 degrees ). There was high patient satisfaction and there were no serious complications.
A Tissue Bank is a valuable adjunct to tumour management. In bone tumours, the defects produced by ablative surgery can be reconstructed using banked tissue, thereby obviating the donor site morbidity associated with autografts. Allografts are especially useful in large defects or in children where the quantity of available autograft is limited. The use of bone allografts in India has been limited by the availability of good quality, affordable grafts. In this article we share our experience with the use of indigenously produced allografts in limb salvage, as bone graft expanders and as struts. Lyophilised, irradiated bone allografts were morcellised and used in 32 patients. In 21 of these patients the allograft was used in contained cavities. Complete incorporation of the graft was seen between 6-9 months in all the 25 cases available for follow-up. In 4 patients the allograft was layered onto autograft. The allograft incorporated with the host bone in only one of these patients.Struts were used in 9 cases (3 cases complete intercalary segmental defect, 3 cases of hemicortical defects, 2 cases of allograft-prosthesis composite around the hip, 1 case an iliac-crest block was used to stop bleeding from an anterior sacral defect). Of these, no incorporation of the full segment struts was observed in 2 patients who were on chemotherapy and radiotherapy. The sacral defect case was lost to follow-up. All the other struts incorporated with the host bone within 6-9 months. In 5 cases there was sterile postoperative drainage. Overall infection was observed in 4 patients (10%). In one the graft was removed, another settled uneventfully with subsequent incorporation of graft, and two have a persisting sinus but good incorporation. Since radiation and lyophilisation are known to affect the material properties of bone, the grafts were rehydrated in saline for 30 minutes prior to transplantation. Autogenous marrow or autograft was used to provide osteoinductive properties. In selected cases the lyophilised, irradiated bone allografts proved to be clinically useful in the reconstruction of large tumour defects.
Tumour excision leaves behind large defects. Allografts provide an excellent alternative to autografts without donor site morbidity and are especially useful in large defects or in children where the quantity of available autograft is limited. In this paper we discuss our experience with indigenously procured and processed lyophilised, irradiated bone allografts. Bone allografts were used in 41 patients. They were used morsellised and used in 32 cases. Of these, 25 cases were available for follow-up. These included 21 patients in whom the allograft was used in contained cavities. Complete incorporation of the graft was seen between 6 and 9 months in all these 21 patients. In 4 patients the allograft was layered onto autograft. In only one of these the allograft incorporated with the host bone. Struts were used in 9 cases (3 cases complete intercalary segmental defect, 3 cases of hemicortical defects, 2 cases of allograft-prosthesis composite around the hip, in 1 case an iliac-crest block was used to stop bleeding from an anterior sacral defect). Of these, 2 full segment struts showed no incorporation. Both these patients were on chemotherapy and radiotherapy. There was no follow-up in sacral defect case. All the other struts incorporated with the host bone within 6-9 months.In 5 cases there was sterile postoperative drainage. All these cases went on to uneventful. Deep infection was observed in 4 patients (10%). In one, the graft was removed, another settled uneventfully with subsequent incorporation of graft, and two have a persisting sinus but good incorporation.To restore part of the strength of the struts it was necessary to hydrate them for 30 min prior to use. Autogenous marrow or autograft was used to provide osteoinductive properties.Conclusion. In selected cases the lyophilised, irradiated bone allografts proved to be very useful in reconstruction of large tumour defects.
OBJECTIVES: To detect Helicobacter pylori DNA in fresh and paraffin-embedded bladder biopsy specimens, and thus determine any possible role in interstitial cystitis (IC). MATERIALS AND METHODS: Thirty-three bladder biopsy samples were examined from patients with IC (29 paraffin-embedded and four freshly frozen) diagnosed according to National Institute of Diabetes, Digestive and Kidney Disease criteria. The positive control was a gastric biopsy sample from a patient with a known gastric ulcer caused by H. pylori infection. RESULTS: The anticipated polymerase chain reaction product size of 109 base pairs was obtained with the positive control, whereas none of the other biopsy samples (paraffin embedded or fresh) showed positive amplification specific for H. pylori. CONCLUSIONS: As there was no H. pylori DNA in any of the samples from patients with IC, it is an unlikely candidate in the pathogenesis of IC.
Unicompartmental knee arthroplasty is now being used more commonly to treat single compartment disease of knee, with very encouraging results. We report on a rare case of common peroneal nerve palsy; 8 years after lateral unicompartmental knee arthroplasty. This palsy was caused by pressure on the common peroneal nerve, due to posterior migration of tibial component.
Salt stress adversely affects the growth of rice plants. To understand the molecular basis of salt-stress response, four subtracted cDNA libraries were constructed employing specific NaCl-stressed tissues from salt-tolerant (CSR 27 and Pokkali) and salt-sensitive (Pusa basmati 1) rice cultivars. An efficient PCR-based cDNA subtraction method was employed for the isolation of the salt-stress responsive cDNA clones. In all, 1,266 cDNA clones were isolated in the course of this study, out of which 85 clones were end-sequenced. Database search of the sequenced clones showed that 22 clones were homologous to genes that have earlier been implicated in stress response, 34 clones were novel with respect to their function and six clones showed no homology to sequences in any of the public database. Northern analysis showed that the transcript expression pattern of selected clones was variable amongst the cultivars tested with respect to stress-regulation.

A 28-year-old man had a desmoplastic medulloblastoma in the vermis and left cerebellum. This tumor was composed of nodular, reticulin-free zones (pale islands) surrounded by densely packed, highly proliferative cells that produced a dense intercellular reticulin network. Some of the cells were heavily pigmented, and this pigment proved to be melanin. Adult age, desmoplastic nature, and melanin pigmentation are some of the rare features of this tumor that need documentation. Further, this pigment was in the primitive cells, unlike in the published cases, in which it was present in the tubular or tubulopapillary component. To the best of our knowledge, this is the first published case of desmoplastic pigmented medulloblastoma, and the patient is the oldest reported to have this tumor.
