Single-stage revision of peri-prosthetic infection following total elbow replacement.

This study reviews the predisposing features, the clinical, and laboratory findings at the time of diagnosis and the results of single-stage revision of prosthetic replacement of the elbow for infection. Deep infection occurred in six of 305 (1.9%) primary total elbow replacements. The mean follow-up after revision was 6.8 years (6 months to 16 years) and the mean age at the time of revision was 62.7 years (56 to 74). All six cases with infection had rheumatoid arthritis and had received steroid therapy. The infective organism was Staphylococcus aureus. Four of the six elbows had a developed radiolucency around one component or the other. Successful single-stage exchange arthroplasty was carried out with antibiotic-loaded cement in five of the six cases. In one, the revision prosthesis had to be removed following recurrence of the infection. The functional result was good in three elbows, fair in one, poor in one and fair in the resection arthroplasty.

Lateral transmuscular or combined interlaminar/paraisthmic approach to lateral lumbar disc herniation? A comparative clinical series of 48 patients.

BACKGROUND: The optimum operative technique for lateral lumbar disc herniations (LLDH) remains unclear, and both interlaminar and extraspinal approaches are used. OBJECTIVE: To compare outcome after LLDH removal either by a lateral transmuscular approach (LTM) or by a combined interlaminar and paraisthmic approach (CIP). METHODS: 28 patients underwent surgery using CIP and 20 using LTM. All patients were operated on by the same neurosurgeon. The clinical presentation of the two groups was comparable. Overall outcome was assessed after a mean follow up period of between 19 and 37 months using the Ebeling classification. In addition, the effect of surgery on radicular pain, low back pain, and sensory and motor deficits was defined. RESULTS: Excellent to good results were achieved in 95% of the LTM group and 57% of the CIP group. The outcome was satisfactory to poor in 5% of the LTM and 43% of the CIP group (p<0.004). The percentage of sensorimotor deficit and of radicular pain improvement was higher in the LTM group. New low back pain was found exclusively in the CIP group (21%). The complication rate was 5% in the LTM group and 11% in the CIP group. CONCLUSIONS: The LTM approach achieves a better overall outcome and improvement in radiculopathy. The complication rate is lower with the transmuscular route and the risk of new low back pain is minimised. These results are likely to be attributable at least in part to the lesser invasiveness of the LTM approach.

One-stage exchange shoulder arthroplasty for peri-prosthetic infection.

There are few reports in the literature of the diagnosis and treatment of the infected shoulder arthroplasty. Most deal with resection arthroplasty and two-stage exchange surgery. We present our results of one-stage exchange operation as treatment for the infected shoulder arthroplasty. Our group comprised 16 patients (ten men, six women) with 16 infected arthroplasties. By the time of follow-up, two patients had died (mean 5.8 years), two could not be located and three had already undergone revision surgery. Nine patients were thus available for clinical examination and assessment. The infections were largely caused by staphylococci, Propionibacterium species and streptococci. Two were early infections (within three months of surgery) and 14 were late infections. The mean follow-up was 5.8 years (13 months to 13.25 years) when the mean Constant-Murley score was 33.6 points and the mean University College of Los Angeles score 18.3 points. Further revision was performed in three patients. One sustained a peri-prosthetic humeral fracture, another developed an acromial pseudarthrosis after transacromial surgery and the third suffered recurrent dislocations. No patient had a recurrence of infection. A one-stage exchange procedure using antibiotic-loaded bone cement eradicated infection in all our patients and we suggest that such a procedure is at least as successful as either a resection arthroplasty or a two-stage exchange in the management of the infected shoulder arthroplasty.

Is "aseptic" loosening of the prosthetic cup after total hip replacement due to nonculturable bacterial pathogens in patients with low-grade infection?

BACKGROUND: Loosening of the prosthetic cup is the limiting factor in the service life of total hip prostheses (THPs). Despite effective culture methods, the detection of low-grade infection in patients with loose implants still presents a challenge. It is crucial to distinguish between "aseptic" loosening and loosening due to periprosthetic infection, so that appropriate treatment can be administered. We investigated whether aseptic loosening of the acetabular components of THPs is due to unrecognized infection. METHODS: From October through December 2002, a total of 24 patients with acetabular cup loosening were investigated. Only patients without clinical signs of infection and with negative results of bacteriologic culture of synovial fluid (obtained by preoperative aspiration) were included in the study. Intraoperative biopsy samples obtained from the neocapsule and synovia (e.g., the interface membrane) were examined by means of routine culture methods and by polymerase chain reaction (PCR) for detection of 16S ribosomal RNA (rRNA). Control subjects included 9 patients undergoing primary hip arthroplasty. RESULTS: C-reactive protein levels and erythrocyte sedimentation rates were slightly elevated in the group with loosening, compared with the control group, but the difference was not statistically significant. PCR and routine culture showed no microorganisms in either group, with the exception of 1 patient in the loosening group. CONCLUSIONS: PCR for detection of 16S rRNA in tissue specimens obtained from hip joints is not superior to routine bacteriologic culture techniques for detection of low-grade infections. However, these results demonstrate that the loosening of cups in THPs do not usually result from nonculturable periprosthetic infection, if the microbiological processing is adequate.

[Hyperpyrexia and rhabdomyolysis after ecstasy (MDMA) intoxication].

Abuse of 3,4-methylenedioxymethamphetamine (MDMA,Ecstasy) is still growing over the last years and reports of severe or even fatal complications, such as arrhythmias, hyperpyrexia, rhabdomyolysis, disseminated intravascular coagulopathy (DIC), acute renal or liver failure or brain oedema are also increasing. We report the case of a 21-year-old male who took a suicidal overdose of MDMA and subsequently developed severe hyperpyrexia (>43 degrees C/109.4 degrees F), rhabdomyolysis with an initial myoglobin level of 88,000 microg/l, disseminated intravascular coagulation (DIC) and beginning renal and liver failure. Infusing dantrolene 140 mg (2.5 mg/kg body weight) i.v. and using supportive cooling was effective in treating hyperpyrexia. To support renal function and diuresis we increased the intravenous fluid supply up to 5 l per day which led to a raised elimination of myoglobin, urea nitrogen and creatinine within 1 week. Hemodialysis was not necessary. DIC was treated according to laboratory parameters by supply of antithrombin (AT) III, fresh frozen plasma, prothrombin complex concentrates (PPSB) and continuous aprotinin 100,000 IE/h.

Microsurgical therapy of symptomatic lumbar juxta facet cysts.

OBJECTIVE: Symptomatic lumbar juxta facet cysts (ganglion and synovial cysts) (JFC) are uncommon lesions of the spine, causing radiculopathy and low back pain. The authors present their experiences with microsurgically treated JFC. This rare pathology is discussed with special focus on therapeutic concepts and long-term outcome. METHOD: The records of 27 patients with symptomatic lumbar JFC were retrospectively reviewed. The clinical data and diagnostic procedures were evaluated. The patient age ranged from 38 to 83 years (mean 61 years). Treatment consisted exclusively of microsurgical excision of the cysts after partial hemilaminectomy. The early surgical results were evaluated 6 weeks after surgery. For assessment of late surgical results (mean follow-up period 70 months), the Finneson and Cooper outcome scale was used. RESULTS: After 6 weeks, the preoperative symptoms were improved in 25 patients (93 %). Long-time follow-up was available in 23 patients. Good (pain improved and able to function well) to excellent (pain free and able to function well) results were still found in 83 % of the patients. With exception of 2 small asymptomatic dural tears and a slight temporary increase of the preoperative paresis, no surgical complications were encountered. One JFC recurred after 4 months and required re-operation with finally good outcome. CONCLUSION: Adequate and definitive treatment in symptomatic JFC consists in microsurgical resection. A partial hemilaminectomy is sufficient for surgical exposure. Excellent long-term outcome can be achieved. Recurrences and surgical complications are rare.

[Pterional orbital decompression in traumatic orbital hematomas].

The results are presented for pterional orbital decompression in 12 patients with symptomatic traumatic retrobulbar hematoma after various traumatic mechanisms. Pre- and postoperative course, neuroradiological findings, additional brain or facial injuries as well as outcome of eye function are analyzed in detail. Mean time delay between trauma and decompression was 56 h (2.4 days), with a wide range from 2 h to 15 days. Preoperative exophthalmos and pupillary disturbances as well as restrictions of extraocular movements decreased in all patients after orbital decompression and removal of the retrobulbar hematoma if the bleeding was localized. Visual acuity remained normal or showed significant improvement in seven patients, four of whom experienced complete recovery. In three patients the eye remained amaurotic. No complications related to the operation were seen. The pterional orbital decompression described here represents an effective alternative approach for patients with sight-threatening retrobulbar hematoma, especially in cases where it is necessary to gain space for the orbit in addition to evacuating space-occupying blood or bone clots and treating neighbouring lesions. Immediate detection and adequate treatment of orbital hematomas is mandatory to achieve an acceptable outcome of eye function.

Follow-up of extended pterional orbital decompression in severe Graves' ophthalmopathy.

BACKGROUND: Compressive optic neuropathy (CON) with visual loss is, apart from corneal exposure and disfigurating proptosis, the most serious clinical sign encountered in Graves' ophthalmopathy. However, numerous different approaches and operative techniques have been proposed for orbital decompression, with varying results and side effects. The purpose of the present study was to analyze peri-operative data and long-term results in patients with severe thyroid-related orbitopathy, treated by extended pterional orbital decompression, comparing its effectiveness to other procedures. METHOD: An extended pterional orbital decompression was performed in 42 consecutive patients (59 orbits) with severe thyroid-associated ophthalmopathy after failure of medical and radiation therapy during an 11-year period. Pre- and postoperative examination included visual acuity, Hertel exophthalmometry, ocular motility, visual fields (Goldmann perimetry) and notification of complications. Long-term evaluation was carried out on average at 11 months postoperatively (range 5-26 months). FINDINGS: Visual acuity improved rapidly from a preoperative average of 0.53 +/- 0.33 (range, 0-1) to 0.77 +/- 0.31 (range, 0-1) postoperatively (p<0.001). Worsening was not seen. An average reduction of proptosis of 3.79 +/- 2.32 mm (range, 0.5-8 mm) was achieved with a mean preoperative Hertel measurement of 24.7 +/- 3.93 mm (range, 15-33 mm) (p<0.001). Double vision and restriction of eye motility was present in 76.3% of patients preoperatively and improved in 63% of patients (p<0.001). No new onsets of not already pre-existing double vision was seen. Complications included two cases of permanent palsy of the frontal branch of the facial nerve. INTERPRETATION: The extended pterional orbital decompression improved vision and decreased proptosis and restriction of extra-ocular movements in patients with severe sight-threatening and disfiguring cases of Graves' orbitopathy and is still an effective and low-risk alternative to other non-neurosurgical operative techniques. Especially new developing postdecompression strabismus can be successfully avoided.

The role of intraoperative magnetic resonance imaging for the detection of hemorrhagic complications during surgery for intracerebral lesions an experimental approach.

BACKGROUND: Intraoperative magnetic resonance imaging (MRI) for guided biopsy or microsurgical resection of intracranial lesions is gaining broader acceptance. It is not known whether intraoperative MRI has the potential to detect hemorrhagic complications of these surgical procedures, because scientific research has so far focussed on the signal characteristics of less acute clots. It is the objective of this experimental study to investigate whether MRI can visualise intracerebral blood within minutes after its occurrence. METHODS: In 26 pigs, a frontal hematoma was produced by injecting autologous blood. Twenty pigs underwent MRI 30 minutes after injection, and 6 pigs within the first 10 minutes. MRI scans were performed on a 1.5T system. T1-weighted spin echo (SE), T2-weighted turbo spin echo (TSE), T2-weighted fluid attenuated inversion recovery (FLAIR), and T2-weighted gradient echo (GE) images were acquired. Depending on the differences of the signal intensities of the hematoma and the surrounding brain, the detectability of the hematoma was rated as good, fair, or poor. RESULTS: None of the induced hematomas were rated to be clearly visible on T1-weighted sequences. Six of the 26 hematomas (23%) were easily detectable on FLAIR sequences, 18 hematomas (69%) on T2-weighted TSE sequences, and 23 hematomas (88%) on the T2-weighted GE sequences. CONCLUSION: Extravasated blood can be identified with a high reliability within minutes after its occurrence on MRI provided that T2-weighted GE sequences are used for imaging. In conclusion, intraoperative MRI is not only of value for guidance of neurosurgical procedures, but also for immediate detection of hemorrhagic complications.

Interferon-alpha 2a treatment of neuro-Behcet disease.

Behcet disease is a multisystemic, chronic, recurrent inflammatory disorder characterized as a triad of hypopyon uveitis, oral aphthae, and genital ulcers. Neurologic involvement in Behcet disease (neuro-Behcet) is common. Neuro-Behcet disease typically manifests late after disease onset, rarely coincides with ocular involvement, and often heralds a poor prognosis for final vision and survival. We present a case of neuro-Behcet disease with neurologic onset concomitant with systemic and ocular involvement that was responsive to treatment with interferon-alpha 2a.

Effect of methotrexate on the temporomandibular joint and facial morphology in juvenile rheumatoid arthritis patients.

Juvenile rheumatoid arthritis is a disease characterized by chronic inflammation in one or more joints; it affects children and adolescents up to 18 years of age. This disease may cause significant skeletal joint destruction, and the temporomandibular joint, like other joints, may become severely affected resulting in aberrant mandibular growth, abnormal dentofacial development, and/or altered orofacial muscle function. Methotrexate is the most common remittive agent used in juvenile rheumatoid arthritis to modify the course of inflammatory destruction of peripheral joints. The purpose of this study was: (1) to evaluate the effect of methotrexate therapy on the prevalence of temporomandibular joint lesions and aberration in craniofacial development in children afflicted with juvenile rheumatoid arthritis; (2) to further examine the relationship between the temporomandibular joint/cephalometric findings and rheumatologic data (ie, age at onset, duration of disease); and (3) to evaluate further pauciarticular- and polyarticular-onset disease in juvenile rheumatoid arthritis and the prevalence of temporomandibular joint lesions and facial dysmorphology. The following information was obtained from 45 patients with juvenile rheumatoid arthritis: (1) routine rheumatologic clinical examination data; (2) anamnestic temporomandibular joint evaluation data; (3) clinical temporomandibular joint examination data; (4) lateral cephalometric measurement data; (5) posteroanterior cephalometric measurement data; and (6) individually corrected axial tomographic data. The results demonstrated the following: (1) radiographic evidence of condylar degeneration was apparent in 63% of all patients with juvenile rheumatoid arthritis with pauciarticular patients showing less temporomandibular involvement than polyarticular patients; (2) polyarticular juvenile rheumatoid arthritis patients receiving methotrexate showed less severe temporomandibular joint involvement than the polyarticular patients not receiving methotrexate; (3) the craniofacial structure was affected to a greater extent in the polyarticular form of the disease; (4) the craniomandibular index scores were significantly greater in the polyarticular group; (5) vertical height asymmetry and chin deviation were noted in more than 50% of the patients; and (6) there was a correlation between the severity of condylar lesions and cephalometric findings (ie, mandibular retroposition, posterior rotation, smaller ramus and mandibular dimensions) and the onset and duration of the disease. In conclusion, under the conditions of this study, methotrexate therapy was effective in minimizing temporomandibular joint destruction and craniofacial dysmorphology in juvenile rheumatoid arthritis patients with the polyarticular form of the disease.

Induction of invasive and degradative phenotype in normal synovial fibroblasts exposed to synovial fluid from patients with juvenile rheumatoid arthritis: role of mononuclear cell population.

OBJECTIVE: To investigate the effect of synovial fluid (SF) from patients with juvenile rheumatoid arthritis (JRA) on proliferation and induction of degradative and invasive phenotype in normal synovial fibroblasts, and to elucidate the contribution of SF cells to this activity. METHODS: SF and/or conditioned medium (CM) from SF cells were evaluated for their ability to (1) stimulate a proliferative response, (2) induce the "activated phenotype" capable of invading cartilage matrix, and (3) promote the release of key matrix metalloproteinases (MMP) in normal synovial fibroblasts. RESULTS: Proliferation of normal synovial fibroblasts exposed to SF or CM from SF cells of patients with JRA was up to 3 times greater than untreated controls. Concomitant with induction of an activated phenotype in the treated synovial fibroblasts, the activated form exhibited up to 250% invasiveness of cartilage matrix compared to untreated synovial fibroblasts (100%), in addition to releasing increased MMP activity, not normally associated with these quiescent cells. This induction was not solely due to tumor necrosis factor-alpha, transforming growth factor-beta, interleukin 1beta (IL-1beta), and IL-6, as SF and/or CM depleted of these cytokines sustained about 40% of their invasive and inducing ability. We observed that the mononuclear cell (MNC) population that infiltrated into the joint cavity secretes this "inducing activity," which can be maintained in culture up to several weeks. CONCLUSION: Our data suggest that the cellular component of SF releases soluble factor(s) that directly or indirectly contribute to (a) proliferation of synovial fibroblasts, and (b) production and release of extracellular MMP by synovial fibroblasts, thereby inducing a degradative and invasive phenotype culminating in cartilage and bone destruction.

The frequency and clinical characteristics of methotrexate (MTX) oral toxicity in rheumatoid arthritis (RA): a masked and controlled study.

To assess the frequency and clinical characteristics of methotrexate (MTX) oral toxicity in rheumatoid arthritis (RA) patients, 51 RA patients receiving MTX and 46 RA patients not receiving MTX were studied. A questionnaire, the credibility of which was tested on four separate patient groups including a group with Behcet's Syndrome, was used as a tool to determine the prevalence of stomatitis by a blind observer. In this first controlled study of the oral toxicity of MTX, prevalence of stomatitis was found in 37.2% in the group taking MTX and 19.5% in the group not taking MTX (P = 0.054). No statistical differences were detected with respect to number, duration, frequency, and site of stomatitis. Two of the 51 MTX taking patients temporarily reduced their MTX dosage and only one patient temporarily terminated MTX treatment. MTX and toxicity is usually of no major clinical concern in the treatment of RA.
