Acute gouty arthritis. Modern approaches to an ancient disease

The principles governing the pathogenesis and treatment of gout have been established with greater clarity than those for almost any other rheumatic disease. The benefits of treatment include the virtual cure of a disabling and deforming disease. Adherence to proper management guidelines provides predictable relief of symptoms for patients and great satisfaction for the treating physician.     

Destructive gouty arthritis of the hip

We present a case of a 19-year old female with systemic pulmonary artery (PA) pressure due to a congenital ventricular septal defect (VSD) and atrial septal defect (ASD). She was pink at rest and cyanotic on exercise. Lung biopsy revealed grade IV pulmonary vascular changes. As a preliminary step PA was banded to increase right-to-left shunt and decrease aortic (Ao) saturation with consequent decrease in PA saturation. After one year, when she was no longer cyanotic, even on exercise, lung biopsy revealed total regression of pulmonary vascular changes. As a definitive procedure VSD and ASD were closed and PA was debanded. Cardiac catheterization one week postoperatively showed PA pressure to be 50% of systemic pressure. We postulate that reversal of pulmonary vascular changes were due to lowered PA saturation. We further believe that lower PA pressure could have contributed to this regression of pulmonary vascular changes. We performed the same procedure in six more patients with similar positive clinical response. This new concept brings renewed hope to many children who otherwise are candidates for heart lung transplantation.     

Mechanisms explaining the onset, course and spontaneous resolution of gouty arthritis

Cytogenetic analysis of short-term cultures from three untreated and one recurrent ependymoma revealed clonal aberrations in three of the four tumors. A posterior fossa ependymoma from a 3-year-old male patient showed trisomy 11 as the sole clonal chromosome aberration. A recurrent spinal ependymoma from a 35-year-old male showed hypertriploid clones with abnormalities involving chromosomes 1p11,7q21, and 10p13. A 62-year-old male patient with a cerebellar ependymoma showed a hypodiploid stem-cell line with clonal structural aberrations of both the long and short arms of chromosome 1, an interstitial deletion of 2q, trisomy 7, and monosomy for chromosomes 11, 13, and 16. A 3-year-old female patient with posterior fossa ependymoma showed a normal 46,XX karyotype. Chromosome 1 aberrations appear to be the most consistent finding in this small series of tumors, with the net loss or rearrangement of chromosome 1 pter-->p22 material from two of the four tumors. These findings, in addition to a previously published case [1], suggest a possible role for genes on the short arm of chromosome 1 in the cytogenetic evaluation of ependymomas.     

The mode of onset of rheumatoid arthritis and seasonal variations

The aim of the study was to establish age and sex distribution, seasonal variations, and mode, of onset in a sample of patients with rheumatoid arthritis. One hundred eighty nine patients (146 women and 43 men), whose age ranged from 18 to 77 yrs. (mean age 49.1, SD 12.93) were included in the survey. In majority of patients the disease started between 31-50 years, whereas in the age group from 21-30 it occurred more frequent in women, and in the age group from 51-60 in men. The onset of rheumatoid arthritis was in almost equal proportions acute or insidious, regardless sex. No difference was found concerning onset of the disease and seasonal variations. However there was a statistically significant correlation between mode of the onset and seasonal variations (P < 0.05). Rheumatoid arthritis started abruptly more often in springtime, and more insidiously in autumn, whereas in summer and winter there was an equal number of patients with acute or insidious onset of the disease.     

Acute arthritis of cats associated with feline calicivirus infection

Twelve specific pathogen-free cats were infected either by intra-articular inoculation or by contact exposure to one of two strains of feline calicivirus (FCV), either F65, a field strain originating from an outbreak of lameness in a group of cats, or a vaccine strain. Following either route of exposure, both strains induced signs typical of FCV infection including oral and nasal ulceration, conjunctivitis and ocular discharge. These signs were of equal severity for both virus strains, but overall, following either route of infection, F65 induced more severe disease than the vaccine strain, with marked pyrexia, lethargy and lameness. Vaccine virus only induced a relatively mild lameness following intra-articular inoculation. Gross pathological and histopathological lesions were seen in some of the joints, but again changes were more severe in the F65-exposed cats. Virus was isolated from both normal and affected joints from both groups of F65-exposed cats, and from a joint from each cat inoculated intra-articularly with vaccine virus. Mild transient lameness was also seen in one of two control cats inoculated intra-articularly, but no pathological changes were seen or virus isolated from joints. A cDNA probe used in RNA dot blot hybridisation experiments was found to be specific and more sensitive than virus isolation in detecting FCV in selected tissues. This may be useful in future studies on the pathogenesis of FCV disease and in studies on viral persistence in FCV carriers.     

Abscess-like gouty tophus of the foot

A silent mutation in B-domain of the estrogen receptor-alpha (ER B) change codon 87 (from GCG to GCC) is clinically correlated with frequent spontaneous abortion and familial history of breast cancer among Caucasian patients. However, none of the 167 Japanese female patients and 46 Japanese female healthy volunteers showed ER B variant. Therefore, this DNA polymorphism might involve a genetic racial difference, and appears not to be correlated with frequent spontaneous abortion or familial history of breast cancer at least among Japanese women.     

Acute psychoses in patients with psoriatic arthritis during treatment with sulfasalazine

A 10-year-old boy with acute promyelocytic leukemia (APL) was treated with all-trans-retinoic acid (ATRA) at a dose of 60 mg/m2/day. Recombinant erythropoietin was also used. The patient parents and other relatives, all Jehova's Witnesses, refused any type of hemotherapy. After 43 days of ATRA treatment complete remission was obtained without the use of hemotherapy. This case exemplifies the advantages provided by ATRA treatment in APL.     

The relationship between social stress and dominance is seasonal in greylag geese

A patient aged 54 with Foix-Chavany-Marie syndrome is described. The syndrome is characterized by facio-pharyngo-glossal diplegia with automatic-voluntary movement dissociation. The cause of the disease were bilaterally located infarcts within internal capsule.     

Nedocromil sodium is rapidly effective in the therapy of seasonal allergic rhinitis

BACKGROUND: Nedocromil sodium has proven to be efficacious in prophylactic and long-term therapy for the treatment of seasonal allergic rhinitis. We examined the speed of onset of intranasal nedocromil sodium (1%) for relief of symptoms due to ragweed allergic rhinitis. METHODS: In a double-blind, placebo-controlled trial, 104 patients received either nedocromil sodium or placebo four times daily. Patients spent 10 hours per day for 2 consecutive days in Iowa City Park during the peak of ragweed season. Only patients who had significant symptoms during 3 hourly baseline assessments received drug. Symptom scores for stuffy nose, runny nose, itchy nose, and sneezing and global symptom summary scores were recorded at 19 hourly time points during the 2 days. In the evening patients recorded symptom scores for the postexposure period. RESULTS: In comparison with placebo, nedocromil significantly improved rhinitis symptoms as evidenced by lower symptom summary scores within 2 hours (p = 0.016). Further, this reduction in rhinitis symptoms was maintained throughout the 2-day pollen exposure period. After patients left the study site, postexposure symptom summary scores were also significantly lower in patients treated with nedocromil compared with those treated with placebo (p < 0.007). CONCLUSIONS: Nedocromil significantly relieved preexisting seasonal allergic rhinitis symptoms during peak pollen exposures within 2 hours of the first dose, and the therapeutic benefits were maintained on a dosing regimen of four times a day.     

Acute suppurative arthritis of the temporomandibular joint. Report of a case

The case reported illustrates a rare but interesting condition. Early treatment is the most important factor in decreasing the high morbidity associated with this infection. Aspiration is a key diagnostic tool for early diagnosis. Surgical intervention should be individually assessed and active physiotherapy is a must to resume normal function of the joint.     

Acute septic arthritis of the hip in children--clinical analyses of 31 cases

This is a retrospective study of 31 cases of acute septic arthritis of the hip in children treated at Chang Gung Memorial Hospital from 1983 to 1989. The average follow-up period was 35 months. Among them, there were 18 males (58%) and 13 females (42%). None were involved bilaterally. Fifteen cases (48%) were below 5 years of age. All cases met the diagnostic criteria including bacteriological results, clinical and radiographic changes. Limited range of motion, fever, and tenderness were the most common symptoms and signs. More than half of the patients (52%) had a leukocyte count of over 15,000/cmm. The erythrocyte sedimentation rate was elevated in 30 cases (97%). Pathogens had been isolated from blood, arthrocentesis fluid, or surgical specimens in 26 cases (84%). Staphylococcus aureus was the most common causative organism (58%). Twenty-seven cases (87%) underwent emergency arthrotomy and debridement. Five (19%) of them received unsatisfactory results. A delay in definite treatment, very young infants, and the association with osteomyelitis of the adjacent bone were the important factors associated with poor prognosis. Four cases (13%) who received only medical treatment showed satisfactory results. Early diagnosis and significant response to antibiotics contributed to this favorable outcome.     

Intranasal fluticasone propionate is more effective than terfenadine tablets for seasonal allergic rhinitis

BACKGROUND: We compared the efficacy and tolerability of the intranasal corticosteroid fluticasone propionate with that of the antihistamine terfenadine in patients with seasonal allergic rhinitis. METHODS: Two hundred thirty-two adults and adolescents with seasonal allergic rhinitis received intranasal fluticasone propionate (200 micrograms once daily), terfenadine tablets (60 mg twice daily), or placebo for 2 weeks in a double-blind, randomized, parallel-group study. Main outcome measures were clinician- and patient-rated individual and total nasal symptom scores (based on ratings of nasal obstruction, sneezing, nasal itching, and rhinorrhea); clinician-rated overall response to therapy; changes in nasal inflammatory cell counts; adverse events; and morning plasma cortisol concentrations. RESULTS: Both clinician- and patient-rated total and individual nasal symptom scores were significantly lower in the fluticasone group than in either the terfenadine group or the placebo group at nearly every measured time point throughout the treatment period. After 2 weeks of therapy, clinician-rated total nasal symptom scores decreased by 49% in the fluticasone group compared with 27% in the terfenadine group and 19% in the placebo group. In general, therapy with terfenadine was not statistically distinguishable from that with placebo based on patient-rated total or individual nasal symptom scores. According to clinician ratings, 64% of fluticasone-treated patients compared with 49% and 44% of patients treated with terfenadine and placebo, respectively, experienced significant or moderate improvement. A greater percentage of fluticasone-treated patients compared with either terfenadine- or placebo-treated patients experienced reductions in intranasal eosinophil and basophil counts after 2 weeks of therapy. No unusual or serious drug-related adverse events were reported. Morning plasma cortisol concentrations after 2 weeks of therapy did not differ among groups. CONCLUSION: Fluticasone aqueous nasal spray, a well-tolerated corticosteroid preparation that can be administered once daily, is more effective than terfenadine tablets or placebo in controlling symptoms of seasonal allergic rhinitis.     

Medication adherence in rheumatoid arthritis patients: older is wiser

OBJECTIVES: To create a profile of individuals nonadherent to their medications in an age-stratified sample (ages 34-84) of community-dwelling rheumatoid arthritis patients. The relative contributions of age, cognitive function, disability, emotional state, lifestyle, and beliefs about illness to nonadherence were assessed. DESIGN: A direct observation approach was used in conjunction with structural equation modeling. All participants were administered a preliminary assessment battery. Medications were then transferred to vials with microelectronic caps that recorded medication events for all medications for the next 4 weeks. PARTICIPANTS AND SETTING: A volunteer sample of 121 community-dwelling rheumatoid arthritis (RA) patients were recruited from newspaper ads, posters, and via informal physician contact from private rheumatology practices in Atlanta and Athens, Georgia. Written verification of the RA diagnosis and a disease severity rating were obtained from personal physicians before patients were enrolled in the study. Patients were tested in a private physician's office, and their medication adherence was monitored electronically for a month in their every-day work and home settings. MEASUREMENTS AND RESULTS: Structural equation modeling techniques were used to develop a model of adherence behavior. Cognitive and psychosocial measures were used to construct latent variables to predict adherence errors. The model of medication adherence explained 39% of the variance in adherence errors. The model demonstrated that older adults made the fewest adherence errors, and middle-aged adults made the most. A busy lifestyle, age, and cognitive deficits predicted nonadherence, whereas coping with arthritis-related moods predicted adherence. Illness severity, medication load, and physical function did not predict adherence errors. Omission of medication accounted for nearly all errors. CONCLUSION: Despite strong evidence for normal, age-related cognitive decline in this sample, older adults had sufficient cognitive function to manage medications. A busy lifestyle and middle age were more determinant of who was at risk of nonadherence than beliefs about medication or illness. Thus, practicing physicians should not assume that older adults have insufficient cognitive resources to manage medications and that they will be the most likely to make adherence errors. Very busy middle-aged adults seem to be at the greatest risk of managing medications improperly.     

Interleukin-2 is found in the synovium of psoriatic arthritis and spondyloarthritis, not in rheumatoid arthritis

Many factors have been reported to stimulate the release of brain natriuretic peptide (BNP) as well as atrial natriuretic peptide (ANP). In hypertensive patients, however, little is known about whether these factors differ from those in normotensive subjects or if they are influenced by antihypertensive treatment. We measured the plasma concentrations of BNP and ANP in 12 hypertensive patients and examined the chronic effects of beta-adrenoceptor blockade on BNP secretion during exercise with a bicycle ergometer. The exercise raised both plasma BNP and ANP with concomitant increases in systolic blood pressure, heart rate (HR) and plasma norepinephrine (NE) and epinephrine (Epi) before and after treatment. Before treatment, the changes in ANP and BNP correlated with that in HR (p < 0.05). After treatment 4 wk of treatment, the change in ANP correlated with those in NE and Epi as well as HR. Multivariate regression analysis indicated that only NE was a significant stimulus for ANP secretion during the treatment period. As for BNP, HR was the only significant stimulant for its secretion both before and after treatment. In essential hypertension, beta-adrenergic receptor blockade affected the factors stimulating exercise-induced ANP release but not those stimulating BNP release. BNP release, therefore, seems to be stimulated by similar but distinct factors from those that stimulate ANP release.
