Ocular assessments in children with NF1 are important as young children may do not complain of visual impairment until it is advanced.

  • Neurocutaneous Syndromes Maria A
    6 Neurocutaneous Syndromes Maria A. Musarella he neurocutaneous disorders are a group of clinically and Tgenetically heterogeneous diseases that are characterized mainly by harmatomas and tumor growth, involving tissues derived by the embryonic germ layer. Older literature has called these disorders “phakomatoses” (mother-spot). The modern nomenclature and traditional eponyms of these entities are given in Table 6-1. Each of the neurocutaneous diseases is rec- ognized as a distinct clinical disorder. This chapter covers the ophthalmic aspects of these syn- dromes, as well as the numerous and varied multisystemic man- ifestations. Although Proteus syndrome and multiple endocrine neoplasia (MEN) 2B are considered separate from the neurocu- taneous diseases, they are covered here because of the clinical resemblance to classic phakomatoses. NEUROFIBROMATOSIS 1 Historical Perspective Dr. Robert William Smith first described neurofibromatosis 1 (NF1) in 1849 in his treatise on Pathology Diagnosis and Treat- ment of Neuroma.100 However, this work received little atten- tion. Neurofibromatosis is most closely linked with the German pathologist, von Recklinghausen, who described the main fea- tures of this entity in his classic paper of 1882.111 Etiology About 50% of cases of NF1 result from new mutations. The NF1 gene has been mapped to 17q11.2 and positionally cloned. The 291 292 handbook of pediatric eye and systemic disease TABLE 6-1. Neurocutaneous Syndromes.

  • Neurofibromatosis Type 1 Presenting with Ophthalmic Features: a Case Paediatrics Section Series
    DOI: 10.7860/JCDR/2016/21041.8780 Case Series Neurofibromatosis Type 1 Presenting with Ophthalmic Features: A Case Paediatrics Section Series GUNJAN JAIN1, VAIBHAV KUMAR JAIN2, INDRA KUMAR SHARMA3, REENA SHARMA4, NEERAJ SARASWAT5 ABSTRACT Neurofibromatosis type 1 (NF-1) is an autosomal dominant disorder involving multiple systems and affects approximately 1 out of 3000 persons. Ocular manifestations are lisch nodules, plexiform neurofibroma, optic pathway gliomas. The proper diagnosis of NF-1 is a crucial task for a clinician due to the various clinical manifestations including vision and life threatening malignancies in few patients, which may arise in the different phases of life. The authors report three cases of NF-1, presenting with ophthalmic symptoms in teenager boys. On further ophthalmic and paediatric evaluation the diagnosis of NF-1 was confirmed on the basis of clinical criteria. This series also describe the abnormal facial features like telecanthus and broad nose which has been reported rarely. Case 1 was kept under regular follow-up and Case 2 and Case 3 were planned for the debulking surgery for plexiform neurofibroma of upper eye lid. A multidisciplinary approach is required to diagnose and treat such patients keeping in mind the myriad of clinical manifestations and life- long follow-up is required. Keywords: Lisch nodule, Plexiform neurofibroma, Telecanthus CASE 1 for such lesions.

  • It Would Be a New Diagnostic Criteria for Type 1 Neurofibromatosis?
    ORIGINAL ARTICLE Choroidal Freckling: It Would be a New Diagnostic Criteria for Type 1 Neurofi bromatosis? Ozer DURSUN1, Ozlem TEZOL2, Erdem DINC3, Mustafa VATANSEVER1, Gülhan TEMEL4, Pınar DURSUN5, Çağlar CITAK6 ABSTRACT Purpose: The aim of this study was to investigate the frequency of choroidal freckling and evaluate the relationship between choroidal freckling (CF) and Lisch nodule in patients with type 1 neurofi bromatosis (NF-1). Materials-Methods: The study included 23 pediatric patients with NF-1 and 24 age- and sex-matched healthy controls. Presence of Lisch nodule was detected by biomicroscopic examination and recorded. The presence of CF was investigated by near-infrared refl ectance imaging after the pupillary dilation with tropicamide 1%. Diagnostic accuracy of CF was evaluated in patients with NF-1. Results: There was no signifi cant difference in age and gender distributions between the patient and control groups (p>0.05, for both parameters). The Lisch nodule was detected in 60.8% of patients, while no Lisch nodule was observed in the control group. The CF frequency was found in 82.6% in the patient group whereas in 4.16% incontrols. The CF frequency was signifi cantly higher in patients with Lisch nodule compared to patients without (p<0.001). The sensitivity and specifi city for CF fi nding were 82.6% and 95.8%, respectively. Conclusion: The present study showed that choroidal abnormalities termed as CF are common in patients with NF-1 and that it would be accepted as a new diagnostic criterion in the following years. However, there is a need for further studies with larger sample size to assess diagnostic accuracy of CD in patients with NF-1.

You are awarded marks for both your communication skills and clinical knowledge, and so it is not enough (although is essential) to just be a good listener – your job is to address patient’s and their family’s concerns appropriately and to provide them with reliable, accurate information about the child’s condition and the ongoing management plan.

Pittsburgh’s NF Clinic serves as a beacon of information and medical expertise for thousands of families in the region. At its founding, in 1989, access to medical specialists and diagnostic testing and technology was sporadic, at best. In the 15 years since, physicians, geneticists, social workers, diagnostic technicians, nurses and other service providers have focused their clinical efforts and research interests, resulting in the highest possible care and guidance for NF patients and their families. The highly unpredictable nature of NF requires a level of cross-specialty coordination and communication unlike that of most disorders. This brochure serves as a base reference for primary care givers who can provide the first and most important intervention by recognizing the early warning signs that lead to early diagnosis. The American Academy of Pediatricians issued these guidelines so you can give a proper diagnosis. 1 1 PEDIATRIC GUIDELINES FOR NF1 1 MANIFESTATIONS OF NF The American Academy of Pediatrics issued the NF and other major genetic disorders affect 13 following guidelines for the medical supervision million Americans of a child diagnosed with NF1.

  • Differentiating Iris Pigmented Lesions: a Primer
    ONCOLOGY CLINICAL UPDATE Differentiating Iris Pigmented Lesions: A Primer hat do you do when a 1 2 patient walks in with a pig- Wmented lesion on the iris? The first thing that likely runs through your mind is: “What exactly am I look- ing at, and what risk does it carry?” Melanocytic growths represent 70% of iris lesions.1 The six most common types that comprehensive ophthalmol- ogists might see in their offices on any 3A 3B given day, according to Carol L. Shields, MD, are: freckle, nevus, Lisch nodules, melanocytoma, melanocytosis, and melanoma. “The last three are the ones to worry about,” said Dr. Shields, at Wills Eye Hospital in Philadelphia.
