Clinical features of patients with chronic spontaneous urticaria associated with autoimmune thyroiditis.

The aim of the study was to focus on children with both chronic spontaneous urticaria (CSU) and autoimmune thyroiditis (AT) as this topic is rarely studied in children although some publications show a higher proportion of antithyroid antibodies in children with CSU. We highlight two cases of children with both CSU and AT and compare their data with reports from the literature. Since only case reports or case series were available, we performed a descriptive analysis of 15 patients. There were 7 (46.7%) cases of hypothyroidism and the rest were euthyroid. Hypothyroidism appears before, during, and after the diagnostic of CSU. One patient with hypothyroidism and one with euthyroidism receiving l-thyroxine experienced remission of urticaria. Three patients over 12 years of age (20%) received omalizumab. Three patients (20%) had another autoimmune disease and seven (58.3%) had a family history of thyroid disease or autoimmune disease. CONCLUSION: Children with CSU need repeated testing for antithyroid antibodies. Children with both CSU and AT require close medical supervision focused on the development of other autoimmune diseases. l-thyroxine may improve urticaria in patients with hypothyroidism, but there is not enough evidence for patients with euthyroidism. Omalizumab may be of benefit in this population but well-controlled studies in children with AT and CSU are needed.

Moraxella osloensis infection among adults and children: A pediatric case and literature review.

Moraxella osloensis has been reported in the literature as a human pathogen, particularly among immunocompromised adults. In contrast to the adult population, most pediatric cases are among patients with no underlying immunological defect; however, no patient underwent further investigation and no data about the long-term follow-up are available. We report the case of a 2-month-old previously healthy girl infected with Moraxella osloensis. Here, we review case reports and case series of children and adults with Moraxella osloensis infection and compare them with our experience. On the basis of our findings, we recommend further investigations (immunological or other underlying diseases) when a child is found to be infected with these bacteria.

[Ischiopubic osteochondrosis revealed by an atypical "acute transient synovitis of the hip": A case report]. / Un cas d'ostéochondrose ischiopubienne révélée par une « synovite aiguë transitoire de hanche ¼ atypique.

We report here the case of a 3-year-old patient, who presented a left limp and a total refusal of walking, without any traumatism. Clinical examination revealed a significant pain in the left leg with a limit to the limiting mobilization. Acute phase reactants were slightly elevated. Based on the hip ultrasound, acute transient synovitis of the hip was diagnosed. Following persistent complaints, a hip plain radiography was performed, showing a discreet reshuffle at the right ischiopubic branch. The MRI of the hip revealed a discrete T2 high intensity centered on the right ischiopubic synchondrosis (IPS), corresponding to a Van Neck-Odelberg osteochondrosis. Non-steroidal anti-inflammatory drugs and limited weight bearing enabled significant clinical improvement. The ischiopubic osteochondrosis is a physiological phenomenon, frequent and mostly asymptomatic. However, when associated with pain, it could easily be mistaken for another musculoskeletal or rheumatological disorder. Therefore, it is important to continue investigating more thoroughly any limping that does not have a typical evolution from the presumed diagnosis.

[Osteoid osteoma in children: 5 cases treated with electrocoagulation]. / L'ostéome ostéoïde de l'enfant : à propos de 5 cas traités par électrocoagulation.

Osteoid osteoma is a benign bone tumor. Its diagnosis is often delayed despite typical symptoms: severe pain mainly situated on the lower limbs and characteristically worse at night. Once diagnosed, an antalgic treatment by aspirin is well known to be very effective in relieving pain. Osteoid osteoma will resolve spontaneously. If symptoms persist despite the use of aspirin, surgery can be performed to remove the tumor. Percutaneous electrocoagulation can be performed instead of surgical resection as a less invasive procedure. The success rate of surgery and percutaneous electrocoagulation is comparable. We reviewed the cases of 5 patients who were hospitalized in our institution for percutaneous electrocoagulation of an osteoid osteoma. We compared them to the literature.
