[Septic dislocation of the hip secondary to BCG vaccination]. / Luxation septique de la hanche secondaire à la vaccination par le BCG.

We report a case of septic dislocation of the hip in an eight-month-old infant secondary to BCG vaccination. The usual treatment of septic arthritis with surgical drainage and broad spectrum antibiotics was unsuccessful. Cure was achieved after institution of an anti-tuberculosis treatment and a second surgical drainage. This rare complication of BCG vaccination can develop several months after administration of the vaccine. Diagnosis is often difficult to establish due to the minimal clinical and non-specific clinical expression. Early radiological signs are also non-specific. Identification of the causal agent can be most difficult. Certain diagnosis is generally achieved after biopsy and pathology examination. Despite the attenuated virulence of the vaccine, anti-tuberculosis treatment is indispensable to achieve cure. Surgery drainage alone is insufficient.

[Osteoid osteoma of the olecranon]. / Ostéome ostéoïde de l'olécrane.

We report a case of osteoid osteoma of the olecranon which developed in the greater sigmoid cavity. The patient was a 22-year-old male who complained of arthritic-like symptoms limited to the elbow joint and progressing for three years. Rheumatoid arthritis then tuberculosis were entertained as possible diagnoses. The diagnosis of osteoid osteoma was not established until the disease had progressed for three years and had already become stiff due to epiphyseal remodeling. Resection of the nidus only alleviate pain and joint motion was not improved.

[Embryonal paratesticular rhabdomyosarcoma: a case report and a literature review]. / Rhabdomyosarcome embryonnaire paratesticulaire: à propos d'un cas et revue de la littérature.

Paratesticular rhabdomyosarcoma is a rare tumor. Multimodality treatment should involve surgery, radiotherapy and chemotherapy, which are indicated according to risk groups. Risk group stratification depends on pretreatment staging and definitive histology. Patients older than 10years or those with suspected lymph nodes on imaging have higher incidence of lymph node involvement. Prognosis is excellent for localized tumors, survival rates exceed 90%. We report a case of embryonal paratesticular rhabdomyosarcoma treated in our institution.
