Juvenile dermatomyositis with joint contractures and calcinosis cutis

A 12-year-old boy presented to our department with firm papules on the fingers of both hands, erythematous scaly plaques on the dorsum of the hands and elbow, and deformities and limitation of motion in the joints of the hands and feet. His parents reported that the eruption started 6 years prior to presentation. He was previously diagnosed with psoriasis by physicians and acitretin treatment was given. However, he did not benefit from the treatment.

A 7-year-old with indurated skin and unilateral progressive joint immobility: A case of stiff skin syndrome

Stiff skin syndrome is a rare sclerotic condition that presents during infancy or early childhood. It has an insidious chronic course and may lead to significant co-morbidity and reduced quality of life. Often, affected individuals experience impaired ambulation and immobilization related to joint involvement. Clinically, it may resemble other sclerotic diseases, so histopathological evaluation is necessary to establish a diagnosis. As it is a condition with limited treatment options, prompt diagnosis and early initiation of physical therapy is crucial to prevent joint restriction and maintain quality of life. We describe a case of a 7-year-old with stiff skin syndrome, and review the literature to discuss the clinical presentation, histological findings, and management of this condition.

[DIAGNOSTIC VARIATIONS OF X-LINKED MUSCULAR DYSTROPHY WITH CONTRACTURES]

Case report with review describes X-linked muscular dystrophy with contractures in 28 years old man and his cousin. The disease revealed itself in an early stage (age 5-10), the process was progressing with apparent tendons retraction and contraction, limited movement in the areas of the neck and back of spine, atrophy of shoulder and pelvic yard and back muscles. Intellect was intact. Cardyomyopathy was exhibited. CK was normal. EMG showed classic myopathic features. Muscle biopsy showed different caliber groups of muscle fibers, growth of endo-perimesial connective tissue. Clinical manifestations together with electrophysiological and histological data suggest consistency with Rotthauwe-Mortier-Bayer X-linked muscular dystrophy.

[Hemiplegia and cerebral palsy - multidisciplinary treatment of the spastic upper extremity]

Spastic hemiplegia and cerebral palsy often lead to typical deformities of the upper extremity. Muscle- and joint-contractures may be painful and aesthetically unappealing and may interfere with function and hygiene. Within the first weeks after the cerebral incidence the vital threat is dominating and the exact amount of neurologic impairment is not assessable. During this period, conservative treatment should counteract the development of contractures. After spontaneous neurologic recovery, surgical options should be taken into account. When choosing surgical procedures, factors as volitional motor control, sensibility and cognition must be taken into account besides the morphologic changes. This is best achieved in a multidisciplinary setting of neurologists, rehabilitation specialists, physiotherapists and surgeons.

Congenital gluteus maximus contracture syndrome--a case report with review of imaging findings

Although the clinical features of gluteus maximus contracture syndrome have been frequently described, imaging features have been seldom described. Most commonly reported cases are those following intramuscular injection in the gluteal region although congenital contracture is an uncommon but important occurrence. This condition has most often been reported in children of school going age. These patients often present with difficulty in squatting, limitation of hip motion or specific deformities and often require surgical correction. We describe the plain radiography, ultrasonography (USG) and magnetic resonance imaging (MRI) features of this condition in a patient with no previous known history of intramuscular injections.

Juvenile hyaline fibromatosis: a case report

Juvenile hyaline fibromatosis is a rare, hereditary disease with distinct clinical and histopathological features. Clinically, it presents with gingival hypertrophy, pappulonodular skin lesions and joint contractures. Bone involvement is usually an uncommon finding. We report a case of a 2-year-old patient, daughter of consanguineous parents, who presented since the age of 2 months with impairment of mental development, multiple joint contractures, motion limitation and nodules on the scalp. The calvarian lesions were surgically removed, and histopathological examination concluded to juvenile hyaline fibromatosis.

Treatment of camptodactyly using injection of botulinum neurotoxin

BACKGROUND

Camptodactyly is usually painless, not caused by trauma, often appearing bilaterally, gradually progressive flexion contracture of the proximal interphalangeal joint mainly on the 5th fingers.

OBJECTIVES

The aim of the study was to analyze the efficacy injecting botulinum neurotoxin in short muscles of the hand responsible for the contraction of the proximal interphalangeal joint.

MATERIAL AND METHODS

The clinical material consisted of 12 patients (8 women, 4 men) treated with injections of botulinum neurotoxin in 2009-2012. Patients were monitored respectively for 2 weeks, 3 and 6 months and then every six months after the procedure. The observation period after injection of toxin ranged from 18 to 36 months. Our proposed method of treatment is inducing a temporary paralysis of muscles (lumbrical, interosseous) by means of botulinum neurotoxin (Botox).

RESULTS

In the majority (10) of patients an improvement and stabilization was achieved just after one injection and there were no disease progression in subsequent controlled studies. These patients continued treatment with usage of redressing extensive splints. In case of the other two patients it was required to repeat the injections.

CONCLUSIONS

The preliminary results obtained are promising. This method of treatment requires further studies and long-term follow-ups every six months until release of symptoms of the disease will be achieved. The operative treatment is reserved for severe deformities.

[Microsurgery for severe flexion contracture of proximal interphalangeal joint]

OBJECTIVE

To investigate the clinical results of cross-finger flap combined with laterodigital pedicled skin flap for repair of severe flexion contracture of the proximal interphalangeal joint.

METHODS

Between October 2008 and February 2011, 11 patients (11 fingers) with severe flexion contracture of the proximal interphalangeal joint were treated with cross-finger flap combined with laterodigital pedicled skin flap. There were 7 males and 4 females, aged 20-63 years (mean, 32.6 years). The causes of injury were crush or electric-saw injury in 7 cases, burn or explosive injury in 3 cases, and electrical injury in 1 case. The locations were the index finger in 4 cases, the middle finger in 2 cases, the ring finger in 2 cases, and the little finger in 3 cases. The mean disease duration was 12.4 months (range, 6-24 months). All cases were rated as type III according to Stern classification standard. The volar tissue defect ranged from 3.0 cm x 1.5 cm to 5.0 cm x 2.5 cm, with exposed tendons, nerves, vessels, or bone after scar relaxation. The defects were repaired with cross-finger flaps (2.2 cm x 1.8 cm to 3.8 cm x 2.5 cm) combined with laterodigital pedicled skin flaps (1.5 cm x 1.2 cm to 2.5 cm x 2.0 cm). Double laterodigital pedicled skin flaps were used in 3 cases. The flap donor site was sutured directly or repaired with the skin graft.

RESULTS

All flaps survived completely and wound healed by first intention. The donor skin graft survived. All the patients were followed up 6-18 months (mean, 11.3 months). The finger appearance was satisfactory. The flaps had soft texture and good color in all cases. No obvious pigmentation or contraction was observed. The contracted fingers could extend completely with good active flexion and extension motion. At last follow-up, the extension of the proximal interphalangeal joint was 10-150. Based on proximal interphalangeal joint motion standard of Chinese Medical Association for hand surgery, the results were excellent in 6 cases, good in 4 cases, and fair in 1 case; the excellent and good rate was 90.9%.

CONCLUSION

It is an easy and simple therapy t o cover wound area of severe flexion contracture of the proximal interphalangeal joint after scar relaxation using cross-finger flap combined with laterodigital pedicled skin flap, which can repair large defect and achieve good results in finger appearance and function.

A novel autosomal dominant inclusion body myopathy linked to 7q22.1-31.1

We describe a novel autosomal dominant hereditary inclusion body myopathy (HIBM) that clinically mimics limb girdle muscular dystrophy in a Chinese family. We performed a detailed clinical assessment of 36 individuals spanning four generations. The age of onset ranged from the 30s to the 50s. Hip girdle, neck flexion and axial muscle weakness were involved at an early stage. This disease progressed slowly, and a shoulder girdle weakness appeared later in the disease course. Muscle biopsies showed necrotic, regenerating, and rimmed vacuolated fibers as well as congophilic inclusions in some of the fibers. Electron micrograph revealed cytoplasmic inclusions of 15–21 nm filaments. A genomewide scan and haplotype analyses were performed using an Illumina Linkage-12 DNA Analysis Kit (average spacing 0.58 cM), which traced the disease to a new locus on chromosome 7q22.1–31.1 with a maximum multi-point LOD score of 3.65. The critical locus for this unique disorder, which is currently referred to as hereditary inclusion body myopathy 4 (HIBM4), spans 8.78 Mb and contains 65 genes. This localization raises the possibility that one of the genes clustered within this region may be involved in this disorder.

Sagittal placement of the femoral component in total knee arthroplasty predicts knee flexion contracture at one-year follow-up

PURPOSE

Flexion contracture has been shown to impair function and reduce satisfaction following total knee arthroplasty (TKA). The aim of this study was to identify modifiable intra-operative variables that predict post-TKA knee extension.

METHODS

Data was collected prospectively on 95 patients undergoing total knee arthroplasty, including pre-operative assessment, intra-operative computer assisted surgery (CAS) measurements and functional outcome including range of motion at one year. Patients were divided into two groups: those with mild flexion contracture (> 5°) at the one-year follow-up and those achieving full extension.

RESULTS

The sagittal orientation of the distal femoral cut differed significantly between groups at the one-year follow-up (p = 0.014). Sagittal alignment of greater than 3.5° from the mechanical axis was shown to increase the relative risk of a mild flexion contracture at one-year follow-up by 2.9 times, independent of other variables.

CONCLUSION

Increasing the sagittal alignment of the distal femoral cut more than 3.5° from the mechanical axis is an independent risk factor for clinically detectable flexion contracture one year from index procedure.

Intrinsic contractures of the hand

Contractures of the intrinsic muscles of the fingers disrupt the delicate and complex balance of intrinsic and extrinsic muscles, which allows the hand to be so versatile and functional. The loss of muscle function primarily affects the interphalangeal joints but also may affect etacarpophalangeal joints. The resulting clinical picture is often termed, intrinsic contracture or intrinsic-plus hand. Disruption of the balance between intrinsic and extrinsic muscles has many causes and may be secondary to changes within the intrinsic musculature or the tendon unit. This article reviews diagnosis, etiology, and treatment algorithms in the management of intrinsic contractures of the fingers.

[Diagnosis and treatment of unilateral gluteal muscle contracture]

OBJECTIVE

To investigate the pathogenesis, diagnosis, and treatment of unilateral gluteal muscle contracture.

METHODS

Between January 1990 and September 2009, 41 patients with unilateral gluteal muscle contracture were treated and the clinical data were retrospectively analysed. Among them, 24 were male and 17 were female with an age range from 6 to 29 years (mean, 12 years). Thirty-nine patients had a definite history of repeat intragluteal injection. The locations were the left side in 9 cases and the right side in 32 cases. The main clinical manifestations included lameness and abnormal gait. The medical examination showed pelvic oblique and relative inequality of lower limbs with a mean difference of 2.1 cm (range, 1.2-3.8 cm) in the distance form navel to malleolus medials. The X-ray films of pelvis showed outpouching trochanter of femur and pelvic oblique. The CT scans showed no abnormal finding except pelvic oblique and gluteal muscle contracture. The arc longitudinal incision was made into the posterolateral area nearby the greater trochanter and then lysis of the gluteal muscles was performed, followed by the skin traction of both legs and rehabilitation exercise.

RESULTS

All incisions healed by first intention. Forty-one patients were followed up 1-20 years (mean, 5 years), and the signs of gluteal muscle contracture disappeared. After 1 year of operation, 34 patients had equal leg length, 5 patients had mild pelvic oblique, and 2 patients had obvious pelvic oblique. According to LIU Guohui et al. evaluation standard, the results were excellent in 33 cases, good in 6 cases, and poor in 2 cases with an excellent and good rate of 95.12% at 1 year after operation.

CONCLUSION

Unilateral gluteal muscle contracture leads to pelvic oblique and inequality of lower limbs, and it can be cured with the surgical release of the gluteal muscle contracture by the arc longitudinal incision into the posterolateral area nearby the greater trochanter, combined with postoperative skin traction and rehabilitation exercises.

Improved, atraumatic access to digits with severe flexor contractures: surgical tape and suture modification of the lead hand

We present a modification to the widely used lead hand retraction system that allows for improved surgical access to a digit with a severe flexor contracture. A simple construct using surgical adhesive tape and a silk suture can be made and applied to the digit and lead hand. Our technique is simple and inexpensive to use, and we recommend its use to improve surgical access without causing unnecessary trauma to the digit.

Objective evaluation of two differently-shaped permanent expander prostheses used for breast reconstruction

When a breast is being reconstructed with an implant, a capsule of connective tissue always forms around the implant and a capsular contracture can develop. Radiotherapy increases the incidence of capsular contracture. To evaluate the results after breast reconstruction with differently-shaped textured implants, and the effect of radiotherapy on the softness of the reconstruction, 140 patients given permanent breast expander prostheses between 1994 and 2000 were studied. In 99 patients a round implant and in 41 an anatomically-shaped implant was used. Radiotherapy was given to 24 patients. For objective assessment, applanation tonometry was recorded when the desired breast volume was achieved, and 6 and 12 months later. This study showed that, regardless of the shape of the implant, the softness of the breast reconstruction was similar, as shown by the contact area of the applanation tonometry disc. Radiotherapy transiently reduced the softness of the breast.

Non-surgical management of ankle contracture following acquired brain injury

BACKGROUND AND PURPOSE

The purpose of this study was to document the outcome of non-surgical management of equinovarus ankle contracture in a cohort of patients with acquired brain injury admitted to a specialist Neurosurgical Rehabilitation Unit.

METHODS

This prospective descriptive study examined all patients with a new diagnosis of moderate to severe acquired brain injury (Glasgow Coma Scale score </=12) admitted for rehabilitation over a 1 year period. Ankle dorsiflexion range and plantarflexor/invertor muscle activity were evaluated weekly during the period of hospitalization. Contracture was defined as maximal passive range of motion </= 0 degrees dorsiflexion, with the knee extended, on a minimum of two measurement occasions. Patients were retrospectively allocated to one of four treatment outcome categories according to ankle dorsiflexion range, type of intervention required and response to treatment.

RESULTS

Ankle contracture was identified in 40 of the 105 patients studied. Contracture resolved with a standard physiotherapy treatment programme, including prolonged weight-bearing stretches and motor re-education, in 23 patients. Contracture persisted or worsened in 17 of 40 cases, all of whom exhibited dystonic muscle overactivity producing sustained equinovarus posturing. Ten of 17 cases required serial plaster casting (+/- injection of botulinum toxin type A) in order to achieve a functional range of ankle motion. Remediation of ankle contracture was not considered a priority in the remaining seven patients due to the severity of their overall disability.

CONCLUSION

The incidence of ankle contracture identified in this population was considerably less than previously reported. Reduced dorsiflexion range was remediated with standard physiotherapy treatment in over half of the cases. Additional treatment with serial casting +/- botulinum toxin type-A injection was required to correct persistent or worsening contracture in one quarter of cases. Dystonic extensor muscle overactivity was a major contributor to persistent or progressive ankle contracture.

Failure of differentiation: Part II (arthrogryposis, camptodactyly, clinodactyly, madelung deformity, trigger finger, and trigger thumb)

The term "failure of differentiation" describes the phenotypes of a large number of otherwise unrelated conditions. The six conditions described here (arthrogryposis, camptodactyly, clinodactyly, Madelung deformity, trigger finger, and trigger thumb) are believed to occur because various structures failed to differentiate normally; however, they have neither common features nor a common cause. We have included information about the history and diagnosis of these conditions, the cause (if known), and the current concepts of treatment and expected outcomes.

Prenatal diagnosis of restrictive dermopathy

We report three cases of Restrictive dermopathy from unrelated families. All were small for gestational age with small eyes and open mouth. Taut, stretched skin caused restriction of movements. Clavicular hypoplasia was a consistent radiological feature. Molecular diagnosis in the parents facilitated prenatal diagnosis from chorionic villous sample (CVS) in the subsequent pregnancy.

A new mitochondrial mutation in a patient with diabetes mellitus, deafness, hydronephrosis and joint contractures

A 28-year-old man presented with multiple flexion contractures of hands and feet, deafness, diabetes mellitus and obstructive nephropathy because of bilateral ureterovesicular stricture. Other prominent clinical findings were short stature, bilateral proptosis, multiple freckles and sacralisation of LS. In order to investigate the role of mitochondrial mutations in various clinical manifestations observed in this patient, we performed mutation screening of 1.6 kb mtDNA around the tRNA (Leu(UUR)) part of 16SrRNA and the ND1 gene. No mutation was present at position 3243 which is associated with diabetes mellitus and deafness. A new point mutation (A/G) at position 4093 of the ND1 gene was found. In conclusion, we found a novel mitochondrial mutation in a patient with diabetes and deafness. This mutation has not been reported before and is the first mutation described in the ND1 gene which is related to insulin dependent diabetes mellitus and deafness and could be specific to the Iranian population. All other unusual clinical findings in this patient can be attributed to the presence of this new mutation.

Isolated adrenocorticotropin deficiency and flexion contractures syndrome

We present a 73-year-old man with isolated adrenocorticotropic hormone deficiency and "flexion contractures" syndrome along with a review of the relevant literature. The patient initially presented anorexia, vomiting, arthralgias, malaise, and weight loss, which progressively deteriorated during the subsequent 6 months. He was admitted to the hospital with fever, confusion, severe cachexia, sinus tachycardia, low blood pressure, hyponatremia, and inability to stand or walk due to severe flexion contractures of the lower extremities (from hips to knees). The flexion contractures were not resolved by physiotherapy or diazepam administration. Due to his life-threatening condition the patient was empirically submitted to glucocorticoid replacement therapy and a remarkable relief from all the above symptoms was observed. A subsequent thorough endocrine investigation suggested the diagnosis of isolated ACTH deficiency (IAD) of unknown pathogenetic mechanism. Hence, in patients with "flexion contractures" syndrome, the pituitary adrenal axis should be evaluated.

[Eosinophilic fasciitis; the importance of early detection for optimal outcomes]

Eosinophilic fasciitis (EF) is a disease with unknown aetiology, although an immunologic pathogenesis is suspected. The characteristic features of this inflammatory disease include scleroderma-like skin indurations, predominantly on the extremities, and peripheral blood eosinophilia. Internal organs are generally not affected. Initiation of systemic glucocorticoid therapy at an early stage results in a good response and remission of symptoms. This is illustrated in 3 cases of EF to demonstrate the importance of early detection in this disease.
