[Fraser syndrome. A case report].

Fraser syndrome is a rare autosomal recessive disorder; the most consistent features are cryptophthalmos, syndactyly of fingers and toes, laryngeal stenosis, and urogenital abnormalities. We report a newborn case at day 1 of life who had multiple abnormalities, born from a consanguineous marriage. Clinically, the newborn had an ankyloblepharon on the left side, a cryptophthalmos on the right side, a syndactyly, anorectal abnormalities with ambiguous genitalia, laryngeal stenosis, and ear malformations. TDM of the cranium and orbits and the transfontanel ultrasound were normal. The abdominal ultrasound showed renal abnormalities. Right eye surgery showed a reduced cornea to an opaque thin plate clinging to the iris without an anterior chamber and a nonindividualized eyeball. The authors discuss the morphological abnormalities, the clinical and paraclinical aspects of this syndrome, its multispecialized clinical management, and the importance of prenatal diagnosis.

[Bilateral optic neuropathy and non-Hodkin's lymphoma].

UNLABELLED: While ocular lesion is commonly known in lymphoma, optic neuropathy is very rare : 1,3% of lymphomas affecting the central nervous systems. OBSERVATION: Authors report the case of a 75 year old patient treated in the haematology department for 8 years, for a large cell B phenotype stage IV lymphoma for which he received 7 chemotherapy courses (CHOP protocol). After a 4 year remission period, he presented a relapse with a rapid progressive bilateral impairment of visual acuity observed for a week before his admission. The ophthalmologic exam revealed no light perception and no afferent reflex on the right eye. There was light perception and weak afferent reflex on the left eye. The anterior segment was normal on both eyes and fundus examination revealed a bilateral stage I papillar oedema. The general exam showed a right facial palsy and an impairment of general condition. The orbital CT scan revealed a significant thickening of both optic nerves caused by lymphomatous infiltration. A chemotherapy with highly dosed IV and intrathecal methotrexate was performed. DISCUSSION: the optic neuropathy is usually associated with a generalized lymphoma with central nervous system involvement, but sometimes can precede the systemic spread of the disease. Apart from infiltration, the optic nerve can be compressed by an intracranial or orbital tumor. The optic neuropathy can also be caused by lymphomatous leptomeningitis.

[Apert syndrome: a reported observation].

Apert syndrome is a type of acrocephalosyndactylia that belongs to the group of craniofacial synostoses. It is characterised by craniofacial dysmorphia and syndactyly of hands and feet. It is an uncommon affection that is often transmitted through an autosomal dominant mode, but sporadic cases are frequent. We report the case of a 2 months old baby brought by his parents to the paediatric emergencies for respiratory distress occurring within the framework of a polymalformative syndrome. The examination showed brachycephaly, bilateral exorbitism, syndactyly of the hands and feet and an anal fistula. Echocardiographic examination showed a cardiovascular malformation (interventricular communication), the whole suggestive of Apert syndrome. The child was admitted in intensive care during five days. He died following a respiratory infection. Through this observation the authors illustrate the clinical and evolutionary aspects as well as the therapeutic difficulties of this affection.

[Ocular and systemic complications of homocystinuria: a report of five cases].

Homocystinuria is an autosomal recessive disorder of methionine metabolism due to cystathionine B-synthetase deficiency. It is the second most common inborn error of amino acid metabolism after phenylketonuria. In addition to the eyes, the skeletal, central nervous and vascular systems are usually affected by homocystinuria. We report two family cases of two sisters and two brothers with homocystinuria revealed by lenticular dislocation into the anterior chamber, associated with mental and growth retardation, and an isolated case of homocystinuria revealed by poor vision with Marfan syndrome and mental retardation. They all underwent surgical lensectomy with anterior vitrectomy under general anesthesia with anaesthesic precautions to prevent vascular thrombosis. Ocular complications are common in patients with homocystinuria. Treatment must include dietary changes to reduce the incidence of ectopia lentis and mental retardation. Surgical treatment with modern microsurgical techniques should be considered in advanced ocular manifestations of homocystinuria.

[Ocular impairment during type II membranoproliferative glomerulonephritis].

Membranoproliferative glomerulonephritis type II (MPGN) is characterized by dense deposits within glomerular basal membrane and Bruch's membrane which result in retinal lesions similar to drusens. We observed a 50-year-old patient with chronic renal deficiency who developed central bilateral serous retinopathy with diffuse punctiforme yellow subretinal lesions. Ophthalmoscopic and angiographic aspects led to an MPGN type II diagnosis. Specific posterior segment lesions are described during MPGN type II. Dense deposits concerned both lamina densa of glomerular basal membrane and Bruch's membrane with choriocapillaris. The main ocular complications were central serous chorioretinopathy and choroidal neovascularization. We review the clinical and evolutive aspects of this disease.

[Weill Marchesani syndrome. Report of a case].

Weill Marchesani syndrome is a congenital disease that combines microspherophakia and skeletal abnormalities. The authors report a 19-year-old male, born of a consanguineous marriage, with a progressive decrease in visual acuity. The general examination showed a squat look, dwarfism, muscle hypertrophy, short hands and feet, and joint stiffness. The ophthalmological examination showed that visual acuity was limited to hand motion in the right eye despite correction and no perception of light in the left eye. Intraocular pressure was 36 mmHg in the right eye and 40 mmHg in the left eye. The anterior chamber was irregular with iridophakodonesis and microspherophakia of both lenses. The zonula was partially ruptured in the right eye. The iridocorneal angle was narrow. Fundus eye examination showed a pale optic disc with an excavation of 9/10 on the right. In the left eye, the optic disc was totally excavated. Cardiovascular check-up revealed rheumatic aortic valvular cardiopathy. The therapy consisted of combined surgery: phakophagia with anterior vitrectomy plus trabeculectomy operated on the right eye. Weill Marchesani syndrome is a rare congenital affection with a recessive autosomal transmission. The visual prognosis is dominated by secondary glaucoma due to pupillary blockage by the mobile eye lens. This observation illustrates the seriousness of spontaneous progression in Weill Marchesani syndrome, justifying the necessity of lens extraction before the onset of complications.

[Cockayne's syndrome with unusual retinal involvement (report of one family)].

Cockayne's syndrome is a very rare autosomal recessive affection. Ocular involvement is an essential element for positive diagnosis; the retina shows a typical salt and pepper retinitis with optical atrophy. We report a family with four brothers who had Cockayne's syndrome with unusual retinal involvement. The patients' parents were first cousins. Ophthalmologic examination of the mother showed unilateral left pigmentary retinopathy localized in the peripapillary region. The father's ophthalmological examination was normal. The four brothers presented disharmonious dwarfism, cutaneous hyperpigmentation of skin areas exposed to sun with old-appearance of the skin, sensorineural deafness, kyphoscoliosis, a cerebellar syndrome and mental retardation. The ophthalmological examination showed hypermetropia in all four brothers and bilateral maculopathy with no papillary or vascular abnormalities. The electroretinogram was in favor of cone dystrophy. Computed tomography showed one case of calcifications of the basal ganglia and cerebral atrophy. The karyotypes of the four brothers and the mother were normal. We discuss the ocular symptoms and the etiopathogenesis of this syndrome.

[Juvenile xanthogranuloma with intraocular involvement. A case report].

Juvenile xanthogranuloma (JXG) is a rare and usually benign disease occurring in early childhood. It causes skin and deep seated lesions, notably in the eye. We report a case of JXG in the iris of a 9-month-old infant. Examination under general anesthesia revealed megalocornea, iris xanthogranuloma occupying the entire anterior chamber and high intraocular pressure. Skin lesions on the left lid and on the back were also found. Ocular hypertension resisted medical and surgical treatment. Cyclodestruction was necessary. The incidence of JXG is low (0.4%). The iris is the most frequently affected ocular tissue. Early diagnosis is necessary to avoid complications. Moreover, JXG can be associated in rare cases with neurofibromatosis or leukemia which must be systematically searched for.

[Isolated and primary palpebro-conjunctival amylosis. Apropos of 2 cases].

Ocular amyloidosis a an uncommon condition and conjunctival involvement rarely occurs, representing 15% of all ocular localizations. Clinical manifestations show a polymorphism requiring a histological diagnosis. Based on two cases of primary isolated conjunctivo-palpebral amyloidosis, we discuss the different ocular sites. The first case involved false ptosis, a conjunctival infiltration and a lower eyelid tumefaction; all located in the left eye. The second case had ptosis, a right lower eyelid tumefaction with ectropion and esthetic damage. Amyloidosis was confirmed at histologic examination of the conjunctival mucous after a special congo red coloration. In order to affirm the isolated conjunctival localization, it is necessary to eliminate another amyloidis site. The treatment was surgical with excision and cure of ptosis. Ocular amyloidosis is a rare condition with polymorphism manifestations. Confirmation is histological. The greatest difficulty is management due to disease recurrence.

[Prevention of nosocomial urinary tract infection: vesical catheter versus Penilex].

Nosocomial urinary tract infection is the most frequent nosocomial infection in many care units. Its main risk factor is the presence of a bladder catheter. Prevention is based upon the enforcement of hygiene recommendations which are not always carefully applied everywhere. We report a prospective study concerning 328 patients divided into two gropus. Group I patients (n = 161) had an indwelling bladder catheter. Group II patients (n = 167) had an external urinary drainage by Penilex. The incidence of nosocomial urinary infection was 2.4% in group II versus 26.7% in group I. Thus preventive efficacy of Penilex use appears to be well demonstrated.
