All of the following are considered lipidoses except (A) Niemann-Pick disease (B) Krabbe disease (C) Tay-Sachs disease (D) X-linked adrenoleukodystrophy (E) Gaucher disease 14 virus under microscope cheap 500 mg tinidazole amex. Which of the following statements is true regarding the genetics of Niemann-Pick disease? This structure remains relatively intact until approximately 34 weeks gestational age bacteria discovery generic tinidazole 500 mg with amex, after which it starts to virus 86 buy generic tinidazole 300mg involute antibiotics for persistent acne purchase generic tinidazole online, a process completed by term. This child most likely has the spastic hemiplegic form of cerebral palsy given that the right side of his body is weak and spastic with increased reflexes (signs of upper motor neuron involvement). Cerebral palsy is a nonspecific term that describes a disability of motor function seen in early infancy. The patients usually have problems with muscle tone (typically spasticity), ataxia, or involuntary movements. Although cognitive, behavioral, and sensory problems can be observed in children with cerebral palsy, these features are not necessary to make the diagnosis. Patients with spastic hemiplegia can have difficulties with gross and fine motor coordination. The child is usually unable to perform a pincer grasp with the affected hand, as was the case with this child. This is often best demonstrated by comparing the affected limb with the opposite normal limb. This needs to be monitored closely because a growth discrepancy of the leg may cause problems with ambulation and lead to further orthopedic difficulties. An older study looking at patients with spastic hemiplegia suggested that up to a third might have mental retardation and/or seizures. A wide range of medical conditions may lead to the spastic hemiplegic form of cerebral palsy including infarction and hemorrhage. Twin gestation also may predispose to cerebral palsy because the infants are at risk for low birthweight. Marked hyperbilirubinemia was once a common cause of choreoathetotic cerebral palsy in the setting of kernicterus. Finally, ingestion of certain toxins, such as methyl mercury, during pregnancy is associated with the subsequent development of cerebral palsy. Intrauterine and neonatal infections can also lead to the development of cerebral palsy. It should be noted that although birth trauma and asphyxia can result in cerebral palsy, they are not the leading causes. These include the following: spastic, choreoathetotic, dystonic, ballismic, ataxic, and mixed. Hence a patient with spasticity and bilateral lower extremity involvement would have spastic diplegia, whereas an individual with 4-extremity involvement would have spastic quadriplegia. Kernicterus is caused by the deposition of bile pigments in various nuclei of the brain (brainstem, cerebellum, and basal ganglia) and spinal cord. Infants with marked hyperbilirubinemia may manifest symptoms as early as the second or third day of life. Sensorineural hearing loss is common and results from degeneration of the cochlear nuclei. Approximately two-thirds of patients have left hemispheric involvement for unclear reasons. Most children with spastic hemiplegia walk by the age of 2 years compared with spastic diplegia where a little more than half walk by 3 years of age. Approximately half of the children with spastic quadriplegia have seizures of the generalized tonic-clonic type. To that extent, all of the interventions listed in this question have been used in the treatment of cerebral palsy. Physical and occupational therapy programs are almost always employed in the overall treatment plan of cerebral palsy. In addition, patients are taught normal movement patterns and methods of compensation. Surgical techniques, such as selective dorsal rhizotomy, which involves cutting half of the dorsal roots, can be employed with the goal of decreasing muscle tone in the affected limb. A primarily white matter process would suggest a leukodystrophy; gray and white matter lesions would be suggestive of a mitochondrial process. Two disorders, globoid cell leukodystrophy (Krabbe disease) and X-linked adrenoleukodystrophy, can present with visual loss. In the early stages, involvement of the parieto-occipital white matter is seen in Krabbe disease, possibly resembling X-linked adrenoleukodystrophy. Because the latter is a peroxisomal disorder, plasma very long chain fatty acids will be increased. Alexander and Canavan disease are 2 leukodystrophies associated with macrocephaly. Confluent areas of increased signal involving the frontal, occipital, and parietal white matter (thick arrows) and of the anterior and posterior portions of the corpus callosum (long stemmed arrows). Glucosylceramide accumulates in various tissues: brain, spleen, bone marrow, and liver. Patients can have myoclonic seizures and a ?cherry red spot (see Figure 138-2) on fundoscopic examination. The disorder is transmitted in an autosomal recessive fashion, especially among those of Ashkenazi Jewish descent. The patient states that he was in his usual state of health until 1 approximately 2 /2 weeks ago when he developed an upper respiratory tract infection. His lower extremities are also weaker compared with the previous day, and he cannot walk 5 meters without support. On physical examination, the patient is an athleticappearing young man in mild distress. His deep tendon reflexes are absent bilaterally in the lower extremities and 1/4+ in the upper extremities. Sensation to vibration and pinprick are slightly diminished in the lower extremities. In evaluating this patient further, which of the following studies could help in confirming the diagnosis? A 15-year-old girl comes to your clinic with the chief complaint of right facial weakness. She was healthy until a couple of weeks ago when she developed an upper respiratory tract infection. Which of the following vitamins can result in a sensory neuropathy if taken in large doses? However, a number of confirmatory studies can be performed to support the diagnosis. A cell count greater than 50 cells/mm should cause consideration of an alternative diagnosis. The protein level may be normal in the first few days but subsequently increases and peaks in 4-6 weeks. Weakness usually starts in the lower extremities and ascends in a distal to proximal fashion. Cranial nerves can be affected with facial diplegia as the most common presentation. If the progression lasts 4-10 weeks, then the term subacute inflammatory demyelinating polyradiculoneuropathy is used. If the progression is chronic or the patient experiences multiple relapses, the condition is termed chronic inflammatory demyelinating polyradiculoneuropathy. But they have been shown to be effective in the treatment of chronic inflammatory demyelinating polyneuropathy. A good history and physical examination can help exclude some of these possibilities. Pain and paresthesias are observed but to a lesser degree than the motor symptoms. Ingestion may cause a sensory and motor peripheral neuropathy, nausea, vomiting, abdominal pain, and alopecia. Although approximately two-thirds of children recover fully without therapy, steroids have been used in the treatment of Bell palsy. Supportive eye care, including placement of an eye patch for protection and eye drops to prevent corneal dryness, is usually needed.

The guidelines are not intended to replace clinical judgment or individualized consultation with medical providers. These guidelines are designed to identify management practices for students with asthma. Health services are made available to students and provided by a school healthcare team led by a school nurse. Although the School Health Services Act addresses the need to plan for, and respond to, any healthcare problem that needs management in the school setting, these guidelines were developed specifically to address the management of students with asthma. The School Health Services Summary provides the number of asthma cases reported at the state and county level as well as average registered school nurse-to-student ratios. Although the need for school health services is increasing, the supply of school nurses remains static or in some cases is decreasing. Asthma attacks, also referred to as episodes, can be caused by exposure to allergens. For children 0?4 years old, if no clear beneft is observed in 4?6 weeks, consider adjusting therapy or alternate diagnoses. Reducing impairment?the frequency and intensity of symptoms currently or recently experienced; and 2. Reducing risk?the likelihood of future asthma episodes, progressive decline in lung function (or, for children, reduced lung growth), or medication side effects. Reduction in lung Evaluation requires long-term Evaluation requires long-term Evaluation requires long-term growth/Progressive loss Not applicable follow-up care. Recommended Action Step up 1 step Step up at least Step up 1 step for Treatment 1 step Consider short course of oral systemic corticosteroids. Consider step down if well controlled for at least weeks, consider adjusting therapy or alternative diagnoses. Consider short Medication course of oral systemic corticosteroids if asthma exacerbation is severe or patient has history of severe exacerbations. Some of these include exercise and sports, prompt management of asthma symptoms, and maintenance of an allergen-free environment. Many children who have asthma experience coughing, wheezing, or excessive fatigue when they exercise. If symptoms occur during usual play activities, a step up in long term therapy is warranted. Participation in physical activity and school sports helps all students, including students with asthma, to feel healthier. The benefits of physical activity include cardiovascular fitness, long-term weight control, and social interaction. In addition, physical activity can help reduce susceptibility to asthma exacerbations. The meal plan should reflect consideration of the developmental needs of the student, as well as food preferences, cultural influences, and family eating patterns. School Environment: Creating an Asthma-Friendly Environment Exposure of students with asthma to allergens to which they are sensitive has been shown to increase asthma symptoms and precipitate asthma exacerbations. Mold Reductions in exposures to allergens and irritants are recommended in environments where the child spends extended periods of time, such as home, daycare, and school. It is important that school staff be aware of these substances and work to minimize them in the school. Judicious use of quick-relief medications and inhaled bronchodilators is an important component in asthma management. The healthcare provider will prescribe a medication and the means of administration specific to the needs of the student. The healthcare provider will also indicate the frequency with which that medication may be given and whether the student has the skills to self-administer. Inhaled medications are preferred because high concentrations of low doses of drug are delivered directly to airways providing potent therapy with few side effects (see Appendix D). In some cases, the healthcare provider will prescribe an oral form of bronchodilator. Students with persistent asthma require a long-term control medication to prevent daily asthma symptoms and to enable them to pursue normal activities. These medications are to be administered once to twice daily and are generally given at home.

When possible, it is best to conduct a planning and implementation meeting before the student starts school. Plan for and provide training, direction, and supervision for both licensed and unlicensed personnel to meet the individualized healthcare needs of the student. The plan of care should comply with local policies and procedures and be formatted according to local standards.

The school should be responsible for assuring that persons are specifically trained to implement the plan of care. The school district, school administrators, and school nurse should be familiar with the school issues and responsibilities associated with students with asthma and assure consistent care through districtwide policies. Several national health and educational organizations have jointly issued guidance regarding students with chronic diseases. School Principal the principal should set the example for the rest of the school-based staff to create a safe environment for the student with asthma. The principal or the administrative designee should participate in Level l: Asthma Awareness Education.
