Juvenile primary Fibromyalgia Syndrome: epidemiology, etiology, pathogenesis, clinical manifestations and diagnosis.

Juvenile primary fibromyalgia syndrome (JPFS) is a chronic, musculoskeletal pain syndrome affecting children and adolescents, most commonly adolescent girls. The syndrome has a multifactorial etiology, with altered central pain processing playing an important role. The hallmark symptom is severe, widespread musculoskeletal pain. Other symptoms include sleep and mood disturbances, headaches, stiffness, and subjective joint swelling. Physical examination can reveal multiple tender points. The diagnosis is clinical, with defined criteria. Early diagnosis and intervention are important. In this part of the review, we discuss the epidemiology, etiology, pathogenesis, clinical manifestations and diagnosis of JPFS. Part two will focus on treatment and prognosis.

[UMBILICAL CORD CORTISOL LEVELS DO NOT CORRELATE WITH 17-HYDROXYPROGESTERONE LEVELS IN THE NEWBORN SCREENING TEST].

BACKGROUND: Cortisol is a stress response marker. During pregnancy and delivery, cortisol levels are elevated, especially in complicated deliveries. Blood cortisol levels can increase 17-hydroxyprogesterone (17-OHP) levels in the mother during delivery, however this effect was not elucidate in newborn infants. OBJECTIVES: To investigate whether there is a correlation between umbilical cord cortisol and 17-OHP levels in the newborn, leading to false results in the newborn screening tests. METHODS: Umbilical cord cortisol levels together with maternal delivery data were analyzed at Meir Medical Center during 2015-2016. The newborn screening test was performed in all newborns at 36 to 72 hours after birth, and data on 17-OHP levels were recorded. A correlation between mode of delivery, umbilical cord cortisol level and 17-OH- P levels of the newborn screening tests was conducted. RESULTS: A total of 122 newborn infants were included in the study. The mean cord cortisol levels were 12.3±4.1 mcg/dL. Vacuum extraction deliveries were associated with the higher cord cortisol level compared to unplanned cesarean section deliveries, planned cesarean sections and vaginal deliveries (all p<0.03). Unplanned cesarean sections had higher umbilical cord cortisol levels compared to planned cesarean section and vaginal delivery ( all p<0.05). All infants had 17-OHP levels within normal limits (<35 nM), with no correlation to umbilical cord cortisol levels (r=0.012, p=0.26). CONCLUSIONS: Vacuum extraction deliveries are associated with the highest cord cortisol level compared to unplanned cesarean section deliveries and to vaginal deliveries, however, these levels are not associated with high levels of 17-OHP of the newborn screening test. Therefore, our data does not support the hypothesis that stressful deliveries are associated with high false positive 17-OHP levels in the newborn screening test.

Pediatric complex regional pain syndrome: a review.

Complex regional pain syndrome (CRPS) is a chronic, intensified localized pain condition that can affect children and adolescents as well as adults, but is more common among adolescent girls. Symptoms include limb pain; allodynia; hyperalgesia; swelling and/or changes in skin color of the affected limb; dry, mottled skin; hyperhidrosis and trophic changes of the nails and hair. The exact mechanism of CRPS is unknown, although several different mechanisms have been suggested. The diagnosis is clinical, with the aid of the adult criteria for CRPS. Standard care consists of a multidisciplinary approach with the implementation of intensive physical therapy in conjunction with psychological counseling. Pharmacological treatments may aid in reducing pain in order to allow the patient to participate fully in intensive physiotherapy. The prognosis in pediatric CRPS is favorable.
