The child’s oral mucosa was viewed slightly red, and chronic pharyngitis was considered on perfect laryngoscopy.

Basic information] Male, 5 years old [Disease type] Tourette’s syndrome [Hospital] Shandong Third Hospital [Date of consultation] September 2020 [Treatment plan] Psychological guidance and medication (zinc gluconate oral solution, calcium carbonate D3 tablets, multivitamin iron oral solution, etc.) [Treatment cycle] Outpatient consultation, 1 week review, 1 month follow-up [Treatment effect] The child’s throat-clearing symptom has been reduced significantly, and the micronutrients have reached the standard. The child was 5 years old and his mother told the doctor that the child’s throat was cleared more frequently, but there were no other clinical symptoms. The child’s oral mucosa was slightly red, chronic pharyngitis could not be ruled out, and laryngoscopy was considered chronic pharyngitis. However, in view of the child’s recurring symptoms of throat clearing and picky eating, it was recommended to complete blood tests, laboratory tests for trace elements, as well as the Tourette’s Syndrome Scale evaluation test, which showed that the child was deficient in a variety of trace elements (zinc, iron, calcium, magnesium), and the scale suggested mild tics, so the diagnosis of Tourette’s Syndrome was confirmed. After detailed communication with the family, we advocated that the child should be given psychological counseling, the family atmosphere should be as relaxed as possible to avoid excessive attention to symptoms, and medications such as zinc gluconate oral solution, calcium carbonate D3 tablets, and multivitamin iron oral solution should be given to supplement micronutrients and correct micronutrient deficiencies. For the pharyngitis condition caused by repeated throat clearing, blue scutellaria oral solution can be given. Parents were instructed to give the child more water and a light and nutritious diet, and the child’s throat clearing symptom was reduced after 1 week, and the relevant trace elements were checked again, and several indicators tended to be normalized. The patient was diagnosed with Tourette’s syndrome after complete examination in the outpatient clinic, and the parents were instructed to give the child standardized medication, and at the same time, cooperate with the corresponding psychological counseling to alleviate the excessive attention to the symptoms of clearing the throat. 1 week later, the parents said that the child’s symptoms of clearing the throat had been reduced, and there were no other special discomforts. After 1 month, the clinic re-examined the child, and this time, all the trace elements were up to standard, and the child’s throat clearing was significantly reduced. It is recommended to re-examine the patient after half a year to clarify the recovery of Tourette’s syndrome. Precautions After active drug treatment, the child’s throat clearing symptom was significantly reduced, as the attending physician was sincerely happy about this. During the recovery period, parents should urge their children to avoid spicy, stimulating, greasy, raw and cold food. Parents should ensure good sleep, 8-10 hours of sleep per day, and avoid staying up all night and working hard. Watch less electronic products and do more outdoor exercise. Families should maintain a relaxed environment to avoid excessive pressure on the child, and can enhance parent-child relationship through games. Pay attention to whether the child’s throat clearing symptom worsens, and whether other symptoms appear, such as making eyes and faces. If the symptoms worsen, it is recommended that the child be followed up in an outpatient clinic. However, parents should not pay too much attention to the symptoms of throat clearing and should not scold the child. V. Personal perception Clearing throat is a common symptom that can be caused by a variety of diseases, such as pharyngitis, Tourette’s syndrome, etc. If the child frequently and for a long time similar performance, parents should be vigilant, and it is recommended that the child go to the hospital to further improve the examination, so as to avoid delays in the condition. Usually should develop good eating habits, do not picky eating, avoid nutritional deficiencies, so as to try to avoid micronutrient deficiencies. For doctors, they should not use medication empirically, and should choose the appropriate medication after a complete examination to avoid missing the diagnosis.
