Contrast sensitivity in 10 year old preterm and full term children: a population based study.
(73/313)
AIMS: To determine the contrast sensitivity (CS) in 10 year old prematurely born children, previously included in a population based study on the incidence of retinopathy of prematurity (ROP), and in full term controls. METHODS: This study included 205 prematurely born children and 215 children born at term, from the same geographical area and study period. CS was assessed monocularly with the Vistech 6500 test at five spatial frequencies (1.5-18 cycles/deg). RESULTS: Prematurely born children had statistically significant lower CS at all frequencies, compared to full term ones. The mean differences in logarithmic CS were 0.03 (1.5 cycles/deg), 0.09 (3 cycles/deg), 0.10 (6 cycles/deg), 0.12 (12 cycles/deg), and 0.19 (18 cycles/deg). Even when the children with ROP and neurological disorders were excluded there was a difference between the two groups. Children who had been treated with cryotherapy had the lowest CS. CONCLUSION: CS was lower in 10 year old prematurely born children than in full term ones of the same age. Whether this finding affects their visual function in daily life is uncertain. (+info)
A controlled clinical pilot trial to study the effectiveness of ice as a supplement to the exercise programme for the management of lateral elbow tendinopathy.
(74/313)
BACKGROUND: The use of ice as a supplement to an exercise programme has been recommended for the management of lateral elbow tendinopathy (LET). No studies have examined its effectiveness. OBJECTIVES: To investigate whether an exercise programme supplemented with ice is more successful than the exercise programme alone in treating patients with LET. METHODS: Patients with unilateral LET for at least four weeks were included in this pilot study. They were sequentially allocated to receive five times a week for four weeks either an exercise programme with ice or the exercise programme alone. The exercise programme consisted of slow progressive eccentric exercises of wrist extensors and static stretching of the extensor carpi radialis brevis tendon. In the exercise programme/ice group, the ice was applied after the exercise programme for 10 minutes in the form of an ice bag to the facet of the lateral epicondyle. Patients were evaluated at baseline, at the end of treatment, and three months after the end of treatment. Outcome measures used were the pain visual analogue scale and the dropout rate. RESULTS: Forty patients met the inclusion criteria. At the end of treatment there was a decline in visual analogue scale of about 7 units in both groups compared with baseline (p<0.0005, paired t test). There were no significant differences in the magnitude of reduction between the groups at the end of treatment and at the three month follow up (p<0.0005, independent t test). There were no dropouts. CONCLUSIONS: An exercise programme consisting of eccentric and static stretching exercises had reduced the pain in patients with LET at the end of the treatment and at the follow up whether or not ice was included. Further research to establish the relative, absolute, and cost effectiveness as well as the mechanism of action of the exercise programme is needed. (+info)
Treatment of keloids and hypertrophic scars.
(75/313)
Clinicians always find it difficult to treat hypertrophic scars and keloids. Various treatment modalities are available. Intralesional corticosteroids, topical applications, cryotherapy, surgery, laser therapy, and silicone sheeting are the widely used options. Radiation therapy can also help in cases of recalcitrant keloids. Most recently, pulsed-dye laser has been successfully used to treat keloids and hypertrophic scars. There are no set guidelines for the treatment of keloids. Treatment has to be individualized depending upon the distribution, size, thickness, and consistency of the lesions and association of inflammation. A combination approach to therapy seems to be the best option. (+info)
Epidermolysis bullosa pruriginosa--report of three cases.
(76/313)
Epidermolysis bullosa pruriginosa, a genetic mechanobullous disease, is characterized by pruritus, lichenified or nodular prurigo-like lesions, occasional trauma-induced blistering, excoriations, milia, nail dystrophy and albopapuloid lesions, appearing at birth or later. Scarring and prurigo are most prominent on the shins. Treatment is unsatisfactory. We report three such cases: two of them first cousins, are described with history of blisters since childhood, followed by intensely pruritic lesions predominantly on the shins, and dystrophy of toenails, but no albopapuloid lesions or milia. Intact blisters were present in one case, and excoriations were seen in the other two. All of them showed encouraging response to cryotherapy. (+info)
Penicillamine induced pseudoxanthoma elasticum with elastosis perforans serpiginosa.
(77/313)
Long term D-penicillamine therapy, especially when used to treat Wilson's disease has been shown to cause elastosis perforans serpiginosa, pseudoxanthoma elasticum perforans and other degenerative dermatoses. We report a 23-year-old male patient who presented with multiple firm papules, nodules over the neck, axillae, front of elbows for five years. He was a known case of Wilson's disease on long-term treatment with penicillamine for the past 12 years. The papulonodular lesions were non-tender and some were discrete while others were arranged in a circinate pattern. There was central scarring of the skin within the circinate lesions. In addition, there were several small yellowish papules on both sides of the neck which eventually became confluent to form plaques. Histopathology confirmed the diagnosis of elastosis perforans serpiginosa and pseudoxanthoma elasticum. He was treated with cryotherapy (using liquid nitrogen through cryojet) for former lesions. The lesions showed remarkable improvement after five sittings. Now the patient is under trientine hydrochloride (750 mg twice daily) for Wilson's disease. (+info)
Cutaneous leishmanasis (CL) may present with unusual clinical variants such as acute paronychial, annular, palmoplantar, zosteriform, erysipeloid, and sporotrichoid. The zosteriform variant has rarely been reported. Unusual lesions may be morphologically attributed to an altered host response or owing to an atypical strain of parasites in these lesions. We report a patient with CL in a multidermatomal pattern on the back and buttock of a man in Khozestan province in the south of Iran. To our knowledge, this is the first reported case of multidermatomal zosteriform CL. It was resistant to conventional treatment but responded well to a combination of meglumine antimoniate, allopurinol, and cryotherapy. (+info)
Cryotherapy for acute ankle sprains: a randomised controlled study of two different icing protocols.
(79/313)
BACKGROUND: The use of cryotherapy in the management of acute soft tissue injury is largely based on anecdotal evidence. Preliminary evidence suggests that intermittent cryotherapy applications are most effective at reducing tissue temperature to optimal therapeutic levels. However, its efficacy in treating injured human subjects is not yet known. OBJECTIVE: To compare the efficacy of an intermittent cryotherapy treatment protocol with a standard cryotherapy treatment protocol in the management of acute ankle sprains. SUBJECTS: Sportsmen (n = 44) and members of the general public (n = 45) with mild/moderate acute ankle sprains. METHODS: Subjects were randomly allocated, under strictly controlled double blind conditions, to one of two treatment groups: standard ice application (n = 46) or intermittent ice application (n = 43). The mode of cryotherapy was standardised across groups and consisted of melting iced water (0 degrees C) in a standardised pack. Function, pain, and swelling were recorded at baseline and one, two, three, four, and six weeks after injury. RESULTS: Subjects treated with the intermittent protocol had significantly (p<0.05) less ankle pain on activity than those using a standard 20 minute protocol; however, one week after ankle injury, there were no significant differences between groups in terms of function, swelling, or pain at rest. CONCLUSION: Intermittent applications may enhance the therapeutic effect of ice in pain relief after acute soft tissue injury. (+info)
Normolipemic papular xanthoma with xanthelasma.
(80/313)
Xanthomas are a common presentation of disorders of lipid metabolism, usually associated with abnormalities of cholesterol metabolism. A 35-year-old woman presented to us with the lesions of xanthelasma on the upper eyelids and papular xanthomas on the rest of the body. Routine investigations and systemic examination were normal. The lipid profile was within normal range and serum protein electrophoresis showed normal pattern. Histopathology from a papular lesion showed foamy histiocytes with Touton giant cells. We present a case of normolipemic papular xanthoma with xanthelasma, a very rare occurrence. (+info)
