Juvenile psoriatic arthritis with nail psoriasis in the absence of cutaneous lesions

INTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 1 2000
Carola Duran-McKinster MD
A 4-year-old white boy without a significant family history had morning stiffness and painful swelling of his left knee and ankle, right elbow, and dorsolumbar region of 2 months' evolution. The following laboratory studies were within normal limits: complete blood cell count, C-reactive protein (CRP), latex, antistreptolysin, and antinuclear antibodies. Rheumatoid factor was negative and an increase in the erythrocyte sedimentation rate (ESR) was detected (56 mm/h). The pediatric department made an initial diagnosis of juvenile rheumatoid arthritis, and treatment with acetylsalicylic acid at 100 mg/kg/day and naproxen at 10 mg/kg/day was started. A thick, yellowish toenail was diagnosed as onychomycosis. No mycologic investigations were performed. Intermittent episodes of painful arthritis of different joints were present. The radiographic features of the peripheral joints included: narrow joint spaces, articular erosions, soft tissue swelling, and diffuse bony demineralization. Characteristic bilateral sacroiliitis and a swollen tendon sheath on the left ankle were detected. At 11 years of age the nail changes had extended to five other toenails and to four fingernails, were yellow,brown in color, and showed marked subungual hyperkeratosis ( Figs 1, 2). The rest of the nails showed significant nail pitting. Trials of griseofulvin alternated with itraconazole in an irregular form for five consecutive years resulted in no clinical improvement, which prompted a consultation to our dermatology department. On three different occasions, KOH nail specimens were negative for fungus, but the presence of parakeratotic cells aroused the suspicion of psoriasis. A complete physical examination was negative for psoriatic skin lesions. A nail bed biopsy specimen was characteristic of nail psoriasis ( Fig. 3). Figure 1. Thickened nails with severe subungual hyperkeratosis in five fingernails Figure 2. Secondary deformity of nail plate. No "sausage" fingers were observed Figure 3. Light microscopic appearance of a nail biopsy specimen showing parakeratotic hyperkeratosis, elongation of interpapillary processes, and Munroe abscess (arrow) (hematoxylin and eosin stain, ×40) The following human leukocyte antigens (HLAs) were positive: A9, A10, B12, B27, Cw1, Bw4, DR6, DR7, DQ1, DQ2, and DR53. A diagnosis of juvenile psoriatic arthritis associated with nail psoriasis was made. Toenail involvement became so painful that walking became very difficult. Occlusive 40% urea in vaseline applied to the affected toenails for 48 h resulted in significant improvement. Currently, the patient is 20 years old with nail involvement, but no psoriatic skin lesions have ever been observed. [source]

Lack of evidence of the effectiveness of primary brachial plexus surgery for infants (under the age of two years) diagnosed with obstetric brachial plexus palsy

Abstract Background, Obstetric brachial plexus palsy, which occurs in 1,3 per 1000 live births, results from traction and/or compression of the brachial plexus in utero, during descent through the birth canal or during delivery. This results in a spectrum of injuries that range in extent of damage and severity and can lead to a lifelong impairment and functional difficulties associated with the use of the affected upper limb. Most infants diagnosed with obstetric brachial plexus palsy receive treatment, such as surgery to the brachial plexus, physiotherapy or occupational therapy, within the first months of life. However, there is controversy regarding the most effective form of management. This review follows on from our previous systematic review which investigated the effectiveness of primary conservative management in infants with obstetric brachial plexus palsy. This systematic review focuses on the effects of primary surgery. Objectives, The objective of this review was to systematically assess and collate all available evidence on effectiveness of primary brachial plexus surgery for infants with obstetric brachial plexus palsy. Search strategy, A systematic literature search was performed using 13 databases: TRIP, MEDLINE, CINAHL, Web of Science, Proquest 5000, Evidence Based Medicine Reviews, Expanded Academic ASAP, Meditext, Science Direct, the Physiotherapy Evidence Database, Proquest Digital Dissertations, Open Archives Initiative Search Engine, the Australian Digital Thesis program. Those studies that were reported in English and published between July 1992 to June 2004 were included in this review. Selection criteria, Quantitative studies that investigated the effectiveness of primary brachial plexus surgery for infants with obstetric brachial plexus palsy were eligible for inclusion into this review. This excluded studies where infants were solely managed conservatively or with pharmacological agents, or underwent surgery for the management of secondary deformities. Data collection and analysis, Two independent reviewers assessed the eligibility of each study for inclusion into the review, the study design used and its methodological quality. Where any disagreement occurred, consensus was reached by discussion. Studies were also assessed for clinical homogeneity by considering populations, interventions and outcomes. Where heterogeneity was present, synthesis was undertaken in a narrative format. Results, Twenty-one studies were included in the review. Most were ranked low on the hierarchy of evidence (no randomised controlled trials were found), and most had only fair methodological quality. Surgical intervention was variable, as were the eligibility criteria for surgery, the timing of surgery and the outcome instruments used to evaluate the effect of surgery. Therefore, it is difficult to draw conclusions regarding the effectiveness of primary brachial plexus surgery for infants with obstetric brachial plexus palsy. Conclusions, Although there is a wealth of information regarding the outcome following primary brachial plexus surgery it was not possible to determine whether this treatment is effective in increasing functional recovery in infants with obstetric brachial plexus palsy. Further research is required to develop standardised surgical criteria, and standardised outcome measures should be used at specific points in time during the recovery process to facilitate comparison between studies. Moreover, comparison groups are required to determine the relative effectiveness of surgery compared with other forms of management. [source]

Effectiveness of primary conservative management for infants with obstetric brachial plexus palsy

Executive summary Background, Obstetric brachial plexus palsy, a complication of childbirth, occurs in 1,3 per 1000 live births internationally. Traction and/or compression of the brachial plexus is thought to be the primary mechanism of injury and this may occur in utero, during the descent through the birth canal or during delivery. This results in a spectrum of injuries that vary in severity, extent of damage and functional use of the affected upper limb. Most infants receive treatment, such as conservative management (physiotherapy, occupational therapy) or surgery; however, there is controversy regarding the most appropriate form of management. To date, no synthesised evidence is available regarding the effectiveness of primary conservative management for obstetric brachial plexus palsy. Objectives, The objective of this review was to systematically assess the literature and present the best available evidence that investigated the effectiveness of primary conservative management for infants with obstetric brachial plexus palsy. Search strategy, A systematic literature search was performed using 14 databases: TRIP, MEDLINE, CINAHL, AMED, Web of Science, Proquest 5000, Evidence Based Medicine Reviews, Expanded Academic ASAP, Meditext, Science Direct, Physiotherapy Evidence Database, Proquest Digital Dissertations, Open Archives Initiative Search Engine, Australian Digital Thesis Program. Those studies that were reported in English and published over the last decade (July 1992 to June 2003) were included in this review. Selection criteria, Quantitative studies that investigated the effectiveness of primary conservative management for infants with obstetric brachial plexus palsy were eligible for inclusion in this review. This excluded studies that solely investigated the effect of primary surgery for these infants, management of secondary deformities and the investigation of the effects of pharmacological agents, such as botulinum toxin. Data collection and analysis, Two independent reviewers assessed the eligibility of each study for inclusion into the review, the study design used and its methodological quality. Where any disagreement occurred, consensus was reached by discussion. Studies were assessed for clinical homogeneity by considering populations, interventions and outcomes. Where heterogeneity was present, synthesis was undertaken in a narrative format. Results, Eight studies were included in the review. Most were ranked low on the Hierarchy of Evidence (no randomised controlled trials were found), and had only fair methodological quality. Conservative management was variable and could consist of active or passive exercise, splints or traction. All studies lacked a clear description of what constituted conservative management, which would not allow the treatment to be replicated in the clinical setting. A variety of outcome instruments were used, none of which had evidence of validity, reliability or sensitivity to detect change. Furthermore, less severely affected infants were selected to receive conservative management. Therefore, it is difficult to draw conclusions regarding the effectiveness of conservative management for infants with obstetric brachial plexus palsy. Conclusions, There is scant, inconclusive evidence regarding the effectiveness of primary conservative intervention for infants with obstetric brachial plexus palsy. Further research should be directed to develop outcome instruments with sound psychometric properties for infants with obstetric brachial plexus palsy and their families. These outcome instruments should then be used in well-designed comparative studies. [source]

The occurrence of congenital heart defects in an inbred herd of pigs in Australia

AUSTRALIAN VETERINARY JOURNAL, Issue 4 2006

Objective To report on the first case of congenital heart defects in pigs in Australia. Design Retrospective analysis of case records from an inbred herd of "Westran' pigs at the University of Sydney, between January 2001 and December 2004. Detailed gross and histological examination of 15 hearts from pigs that had died or were euthanased in 2004. Case Details The necropsy records from a population of 471 pigs that had died (106 pigs) or were euthanased for research purposes (365 pigs) were analysed and the incidence of heart defects recorded, together with basic demographic data. No attempts were made to diagnose the condition in live pigs. Results Congenital heart defects were diagnosed in 6.4% of pigs but this is likely to be an underestimate of the incidence of the deformity. Eighteen pigs died on the farm as a result of the defect, and 12 pigs were diagnosed with the defect as an incidental finding. The most common abnormality seen at necropsy was a sac-like dilatation on the right lateral surface of the right atrium. This was associated with secondary deformity and hypoplasia of the adjacent left ventricle, interventricular region and part of the right ventricle. All hearts showed atrial septal defects of varying size. Conclusion This is the first reported case of congenital heart defects in pigs in Australia, and one of less than five reported cases of atrial septal defects in pigs in the world. The authors conclude that there may be an element of genetic predisposition to the malformation, since it has only been reported in this inbred line of pigs. [source]
