[Magnetic resonance imaging of of the right extraocular muscle paths in healthy persons and in patients with high myopia].

PURPOSE: To investigate the paths of the rectus extraocular muscles (EOMs) in patients with high axial myopia, using high-resolution magnetic resonance imaging (MRI). METHODS: Coronal MR images (T1 weighting) of the orbit were obtained with controlled gaze. Positions of recti EOMs were measured digitally in the middle of the orbit, using the NIH-image analysis software. Orbits of three different patient groups were analysed. Group 1 (n = 14 orbits): Patients with high axial myopia and restrictive eye motility. Group 2 (n = 8 orbits) subjects with high axial myopia and normal eye motility. Controls (n = 11 orbits) with normal eye motility and no refractive error. RESULTS: In comparison to the controls, patients with high axial myopia were found to have significant misplacement of the recti EOMs. Thus in group 1 (group 2 within brackets) the lateral rectus muscle (LR) was misplaced 2.9 (1.4) mm into the lower temporal quadrant p < 0.001 (p = 0.07). The course of the superior rectus muscle (SR) was shifted 1.5 (1.5) mm medially p = 0.02 (p = 0.03) and the path of the inferior rectus muscle (IR) 1.3 (1.3) mm medially p = 0.06 (p = 0.06). The medial rectus muscle (MR) showed a 1.3 (1.2) mm downward mislocation p = 0.01 (p = 0.07). CONCLUSIONS: In patients with high axial myopia (group 1 and group 2) misplacement of all rectus EOMs could be demonstrated by high resolution MRI with controlled gaze. All patients showed an approximately equal amount of MR, SR and IR mislocation. However, misplacement of the LR was significantly greater in patients with high myopia and restrictive eye motility (group 1) than in those without restrictive ocular motility (group 2), p = 0.03. We therefore assume that LR downward mislocation is a major determinant for restrictive eye motility in high myopia.

Soluble and cell surface ICAM-1 as markers for disease activity in multiple sclerosis.

OBJECTIVE: The intercellular adhesion molecule-1 (ICAM-1) is a member of the Ig supergene family. ICAM-1 is expressed on various cells like peripheral blood lymphocytes, endothelial cells or thymic cells and the cell surface form is supposed to be shed into a soluble form. The expression of ICAM-1 is induced by cytokines like Interleukin-1, TNF alpha or interferon gamma. The aim of the study was to investigate whether changes of cell surface and soluble ICAM-1 in the cerebrospinal fluid (CSF) and blood are indicative for disease activity in patients with multiple sclerosis (MS). MATERIAL AND METHODS: In all patients with relapsing-remitting MS (relapse: n=31, remission: n=11) and controls (n=13) the expression of cell surface ICAM-1 (c-ICAM-1) was determined by two colour flow cytometry. Soluble ICAM-1 (s-ICAM-1) was measured by ELISA. Follow-up examinations were done 3 months later. RESULTS: In 31 patients with a current relapse we found significantly decreased expression levels of c-ICAM-1 on leukocytes in CSF (P<0.001) and blood (P<0.10), when compared to those 11 individuals experiencing remission. In contrast we observed significantly (P<0.05) increased levels of s-ICAM-1 in CSF of patients with relapses. Comparing patients who had been in remission for more than 4 weeks (n=11) with remission lasting longer than 3 months (n=28) we detected stable c-ICAM-1 expression on CD3+ T cells in blood. CONCLUSION: Our results demonstrate for the first time that c-ICAM-1 on CD3+ T-cells in CSF and blood is an activity marker in MS.

Efficacy of urea therapy in children with ichthyosis. A multicenter randomized, placebo-controlled, double-blind, semilateral study.

BACKGROUND: Ichthyoses are genetic disorders of keratinization which are uncomfortable due to their conspicuous scaling, itching and cosmetic problems. Especially in childhood, ichthyoses can lead to social discrimination and psychological problems. Efficient therapies are necessary which are safe and well tolerated. OBJECTIVE: The aim of the study was to investigate the keratolytic and moisturizing properties as well as the tolerance of a new urea lotion when applied to hyperkeratotic and ichthyotic skin in childhood. METHODS: The study was conducted as a multicenter, randomized, placebo-controlled, double-blind, semilateral investigation. Sixty children between 1 and 16 years treated one side of the most affected extremity with Laceran 10% urea lotion for 8 weeks. On the other side the urea-free Laceran lotion base was given. On each side of the body a control area was left untreated. The investigators evaluated the global severity of ichthyotic symptoms with the help of a visual analogue scale. RESULTS: The analysis of the global estimation of severity of ichthyosis showed improvements being stronger in the body areas treated with Laceran 10% urea lotion (from 4.8 to 2.0 points) than in the areas treated with the urea-free Laceran lotion base (from 4.8 to 2.5 points). The response rates were 65% after 4 weeks and 78% after 8 weeks for Laceran 10% urea lotion, 50% after 4 weeks and 72% after 8 weeks for the urea-free Laceran lotion base. CONCLUSION: It can be ascertained that Laceran 10% urea lotion has a strong positive effect on generalized ichthyotic keratinization disorders.

Elucidation of restrictive motility in high myopia by magnetic resonance imaging.

OBJECTIVE: To elucidate the cause of an acquired, restrictive motility disorder in patients with high myopia. METHODS: Magnetic resonance imaging (MRI) scans were obtained from 37 patients with high myopia (axial length of globe, 29.4 mm; refractive error, > -15 diopters). Additional dynamic MRI scans were obtained in which the patient fixated in various positions with the less restricted eye for 50 seconds. Twenty normal orbits were studied in control MRI scans. RESULTS: The path of the lateral rectus, in the anterior and midorbital regions, was displaced downward an average of 3.4 mm in 13 patients with typical esotropia and hypotropia. This mislocation reduces abducting torque of the lateral rectus and creates depressing and extorting moments. The muscle insertions were normal, except where previous strabismus surgery relocated them. Contact between the enlarged globe and the bones of the orbital apices that would cause esotropia was not observed. CONCLUSIONS: This eye muscle abnormality in patients with high myopia is another strabismus syndrome related to abnormalities of orbital connective tissues and muscle paths. Orbital MRI scans may be useful before strabismus surgery in patients with high myopia. If an abnormal lateral rectus path is found, surgery should be directed to normalize it. Magnetic resonance imaging morphometry in high myopia may give additional information on orbital anatomy and biomechanical mechanisms of strabismus.

[Green hair caused by frequent swimming pool use].

Three patients presented with an acquired green discoloration of their scalp hair. History revealed that all of them swam regularly in private swimming pools. Examination of the hair by atomic emission spectroscopy showed that the green discoloration was caused by an excessively high copper content of the hair. This exogeneous discoloration is characteristically related to the uptake of copper from private swimming pools.

[Nuclear magnetic resonance tomography diagnosis of eye motility disorder in high-grade myopia for planning an eye muscle operation].

BACKGROUND: This study was conducted to elucidate the etiology of the acquired, restrictive motility disorder in patients with severe myopia by magnetic resonance imaging (MRI) and intraoperative situs and to verify existing theories about strabismus to develop appropriate methods of eye muscle surgery. METHODS: Thirty-five patients with unilateral or bilateral high-degree myopia and strabismus, i.e., axial length of the globe averaged 29.4 mm. Multiple coronal, transversal and parasagittal MRI planes were obtained using a Siemens Magnetom (SP 63) 1.5 Tesla MRI scanner (TR = 550 ms, TE = 15 ms; field of view = 21 x 21 cm; pixel matrix = 256 x 512; 3 acquisitions; slice thickness 2 mm; distance factor 0.25). In addition, in a dynamic MRI the patient had to fixate with the less restricted eye for 50 s in different gaze positions. All data were validated by measurements during strabismus surgery. Twenty normal orbits were studied in control MRI scans. RESULTS: The major MRI finding was dislocation of the lateral rectus in the anterior and midorbital region at an average of 3.4 mm into the temporocaudal quadrant in 13 cases with the typical eso- and hypotropia. This dislocation will reduce the abducting torque of the lateral rectus and create depressing and extorting torques. Two-anatomical explanations are possible: (1) increasing stretch of the lateral rectus because of temporocranial distension of the globe and inability of intermuscular membranes and pulleys to stabilize the path of the lateral rectus; (2) dehiscence of the lateral levator aponeurosis. The restrictive motility disorder was never caused by contact between the enlarged globe and the bones of the orbital apices. CONCLUSIONS: Until now, an abnormal path of recti EOMs has been known only in Duane's syndrome. Prior to strabismus surgery in patients with high-degree myopia, an orbital MRI scan may be useful. If misalignment of the lateral rectus is detected, the most important aim of eye muscle surgery is to normalize the pathological path of the lateral rectus. MRI morphometry in severe myopia may give additional information on the anatomy of the orbit and biomechanical mechanisms of strabismus. Our findings demonstrate the necessity of fixation-controlled MRI scans.

[The revised WHO classification of brain tumors. Radiological aspects of 4 new tumor entities].

PURPOSE: Characterisation of the classification of brain tumours authorized by the WHO. METHOD OF APPRAISAL: This classification was revised and published in its second version. In the revision, some tumours were regrouped histogenetically and some tumour variants were added. Radiologically relevant changes of the classification include the differentiation of four new tumour entities that are easily distinguished by MR imaging. These four tumours belong to the group of childhood tumours or tumours occurring in early adulthood and are characterized by a good prognosis after extirpation. RESULTS OF APPRAISAL: Central neurocytomas are small-cyst ventricular tumours associated with the foramen of Monroi and show moderate contrast enhancement. Infantile desmoplastic gangliogliomas/astrocytomas commonly consist of a solid tumour portion related to the leptomeninges with pronounced contrast enhancement and a typically very large cyst. Pleomorphic xanthoastrocytomas are circumscribed cortical tumours and usually show very moderate gyriform enhancement with only slight signs of a mass effect. Dysembryoblastic neuroepithelial tumours, which originate in the cortical/ subcortical region, likewise show no mass effect; they are characterised by thickening of the cortex from surrounding dysplastic tissue and erosion of the calotte.

A novel dinucleotide mutation in keratin 10 in the annular epidermolytic ichthyosis variant of bullous congenital ichthyosiform erythroderma.

Annular epidermolytic ichthyosis has recently been delineated as a distinct clinical phenotype within the spectrum of epidermolytic keratinization disorders. The pattern of inheritance of the disorder is consistent with an autosomal dominant mode of transmission. Here we report a second incidence of this disorder in a family with two affected generations. The proband suffered from bullous ichthyosis and had bouts of disease activity associated with the development of numerous annular and polycyclic erythematous, hyperkeratotic plaques on the trunk and the proximal extremities. Histologic examination showed the typical pathology of epidermolytic hyperkeratosis, and ultrastructural analysis revealed abnormal keratin filament networks and tonofilament clumping with a perinuclear distribution. Molecular analysis revealed a novel tandem CG to GA 2-bp mutation in the same allele of keratin 10 in affected individuals, resulting in an arginine to glutamate substitution at residue 83 (R83E) of the 2B helical segment. We conclude that annular epidermolytic ichthyosis should be considered a variant of bullous congenital ichthyosiform erythroderma.

New approach in strabismus surgery in high myopia.

AIMS: To develop appropriate methods of eye muscle surgery in highly myopic patients with esotropia and hypotropia, with respect to the pathological findings in high resolution magnetic resonance imaging (MRI). METHODS: 35 patients with unilateral or bilateral high myopia and strabismus--that is, axial length of the globe averaged 29.4 mm. Multiple coronal, transverse, and parasagittal MRI image planes were obtained using a Siemens Magnetom 1.5 tesla MRI scanner. In 15 patients with a pathological plane of recti extraocular muscles found by MRI and confirmed intraoperatively, a new technique of eye muscle surgery was performed to re-establish the physiological muscle plane. This was checked postoperatively in addition to the measurement of alignment and motility by MRI. RESULTS: The new MRI finding of a dislocation of the lateral rectus (LR) into the temporocaudal quadrant by 3.4 mm requires new surgical techniques. Only fixing the LR in the physiological meridian at the equator with a silicone loop ('guide pulley') or a non-absorbable suture is a causal therapy. This yields alignment and improves abduction and elevation. CONCLUSIONS: If the described misalignment of the LR is detected by MRI, a common high dosage recess-resect procedure for esotropia may even aggravate the deviation. The most important aim of eye muscle surgery is to normalise the pathological path of the LR. The restoration of the physiological function of the dislocated LR is remarkable.

Higher frequency of atopic dermatitis and decrease in viral warts among children exposed to chemicals liberated in a chemical accident in Frankfurt, Germany.

BACKGROUND: In february 1993, a major accident occurred in a chemical plant in Frankfurt, Germany, resulting in the emission of a cloud containing 10 m3 of chlorinated and azo compounds such as o-nitroanisole. An inner zone of the suburb Schwanheim was severely polluted. OBJECTIVE AND METHODS: To assess possible long-lasting effects of this environmental accident on the incidence of skin diseases, we examined a total of 511 children from the inner and outer zones of Schwanheim 18 months later and compared the findings to those obtained from a control group of 143 children from the Frankfurt area and South Hessen. For 402 children of the exposed group, information about the exposure status was available, clearly defining presence of absence in the inner zone at the time of the accident. RESULTS: We observed an overall increase in atopic dermatitis among children present during the accident with an odds ratio of 2.44 (95% CI: 1.25-4.76, p value = 0.009). The prevalence of atopic dermatitis was most marked among exposed children in the age group of 6-12 years with a peak of 22.1% compared to 9.2% in the control group and 11.7% among non-exposed children from the outer zone. All cases of atopic dermatitis were mild, however, and did not require hospital treatment. A history of atopic dermatitis was obtained in 20.3% of all children. In the inner zone, 34.2% of the present cases with atopic dermatitis had a previous history of this disease compared to 31% in the outer zone and only 16.2% in the control group. Other skin diseases, such as birthmarks, congenital skin tumours, psoriasis or acne, did not differ, except for viral warts (verrucae vulgares), which were much more frequent in the control group. CONCLUSIONS: The data suggest that acute exposure to a major chemical burden is a risk factor that contributes even after the considerable time period of 1.5 years to the exacerbation of latent and also the development of 'new' atopic dermatitis.

Transcranial duplex monitoring discloses hemorrhagic complication following rt-PA thrombolysis.

INTRODUCTION: Transcranial color-coded sonography (TCCS) allows imaging of basal cerebral arteries as well as brain parenchyma. It may therefore serve to monitor thrombolysis in acute stroke. CASE DESCRIPTION: rt-PA thrombolysis was performed in a patient, suffering from paradoxical embolism causing MCA occlusion. Hemorrhage immediately after completion of rt-PA infusion as well as delayed MCA recanalization could be monitored by TCCS. CONCLUSION: TCCS is useful to improve monitoring and safety of systemic thrombolytic treatment.

Hystrix-like keratosis with nail and joint-involvement: a new genodermatosis?

BACKGROUND AND OBJECTIVE: We describe a familial disorder featuring hystrix-like keratosis, thickened nails and plantar hyperkeratosis. The index patient, a 10-year-old girl, suffered also from joint laxity and had long fingers, while in her mother only the typical skin lesions were observed. METHODS AND RESULTS: Histologic examination of the spiny hyperkeratoses in the index patient showed parakeratosis with marked cornoid lamella. On electron microscopy the keratinocytes exhibited intracellular vacuolization and aggregated tonofilaments, but no concentric shell formation. CONCLUSION: The striking skin lesions present in the 2 cases can be distinguished from other forms of hystrix-like hyperkeratoses such as nevus corniculatus or multiple digitate hyperkeratoses and hence may represent a new autosomal dominant genodermatosis.

The scleroatrophic syndrome of Huriez: a cancer-prone genodermatosis.

We report a 24-year-old woman, her 6-year-old son and her 17-month-old daughter, who all suffer from a rare congenital genodermatosis first delineated by Huriez et al. in the 1960s. The clinical features of this autosomal dominant condition include scleroatrophy of the hands and feet, nail hypoplasia, mild palmoplantar keratoderma and hypohidrosis. Histological changes are non-specific, but immunohistological and ultrastructural examination in our index patient revealed an almost complete absence of epidermal Langerhans cells in the affected skin. This new finding may be linked to the cancer proneness of the scleroatrophic skin. In this family, the grandmother had died at the age of 37 years from metastatic squamous cell carcinoma which had arisen on the thenar eminence.

[Acquired ichthyosis-like skin disease. A challenge for diagnostic evaluation].

We report on four patients with acquired ichthyosis-like skin lesions seen in our out-patients' clinic in the last 6 years. Emphasis is placed on the case of a 25-year-old patient who suffered from mycosis fungoides with the clinical features of an acquired ichthyosis-like condition. Three further observations illustrate the broad clinical spectrum of acquired ichthyosis-like dermatoses. In these patients renal insufficiency, HIV infection or an extreme diet were the cause of the skin lesions. Our observations emphasise that an acquired ichthyosis-like condition should be regarded as a challenge to make a definite diagnosis. Guidelines for a step-by-step diagnostic procedure are proposed.

[Craniocerebral trauma in childhood].

Depending on the clinical symptomatology, computed tomography (CT) is the predominant examination technique. CT reliably shows live-threatening intra- or extracerebral hemorrhage. Typical localization and distribution of blood allow differentiation between extradural and/or subarachnoidal effusion. Dislocation of the midline structures or of cortical relief shows the mass effect of intracranial hemorrhage. In many cases localized edema can be identified, but because of the normally very narrow cortical sulci in children and younger people, the general post-traumatic brain swelling is often diagnosed only retrospectively. Magnetic resonance tomography is more sensitive than CT concerning subtle changes in the depth of the white matter and should be used for follow-up studies as a supplementary examination.

Unstable pre-mutation may explain mosaic disease expression of incontinentia pigmenti in males.

Mosaic skin lesions following the lines of Blaschko are found in boys affected by incontinentia pigmenti (IP). For an X-linked gene defect, this is rather surprising. To explain the mosaic disease expression of IP in males, we propose that the disease is caused by an unstable pre-mutation, which normally remains silent in males during early embryogenesis. Occasionally "silencing" is incomplete and gives rise to clinical manifest IP reflecting a mosaic state of alleles with the full and the pre-mutation in the same patient. This model can account for mother-to-son transmission of IP and for disparate phenotypes in monozygotic female twins.
