RESUMO
Calcinosis is defined as a biomineralization occurring in soft tissues leading to ectopic calcification. Isolated and localised calcification in a muscle is rare, and it is called calcinosis circumscripta in opposition to calcinosis universalis wich is seen in juvenile dermatomyositis and polymyositis. According to laboratory findings and clinical history, calcinosis circumscripta can be metastatic, dystrophic or idiopathic. Masseter muscle is rarely involved. Pre-operative diagnosis of masseter idiopathic calcinosis is a challenge because of many differential diagnosis. Here, we report a case of 22 years old women presented with swelling over left middle third of her face. Clinical history, morphologic and laboratory examinations helped considering such a rare diagnosis.

Nocardia infection is an uncommon and rare condition in immunocompetent patient. A case of cutaneous nocardiosis complicated with osteomyelitis of the vault scalp in a 64-year-old man, with no remarkable past medical history, is reported. Treatment with trimethoprime-sulfamethoxazole than doxycycline for 12 months led to complete resolution and no evidence of recurrence was noted. Nocardia infection should be considered even in immunocomptent patients and doxycycline is a good alternative for treatment.

A regular therapeutic drug monitoring (TDM) of isoniazid could be useful to predict the acetylation profile and to prescribe doses associated with optimal efficacy and safety. We aimed to assess the usefulness of isoniazid TDM in the Tunisian population, to describe the acetylation profile distribution in this population, and to investigate the influence of certain parameters on acetylation phenotype. We performed a retrospective study including Tunisian patients with tuberculosis underwent an isoniazid TDM. Isoniazid concentrations were measured 3 hours after drug intake (C3 ). Subsequent isoniazid doses were adjusted to maintain the C3 within the recommended target (1-2 µg/mL). Patients were qualified as slow acetylators (SAs) or rapid acetylators (RAs) according to their acetylation index. Among the 255 patients, 58% were SAs and 42% were RAs. Of all patients, only 30.6% had a C3 value within the target range. A dose adjustment has been performed for patients with C3 outside the target range. C3 was controlled in 77 patients. It became within the target range in 39 patients (50.6%). The median recommended isoniazid weight doses for SAs and RAs were 2.1 ± 0.7 mg/kg and 4.2 ± 1.4 mg/kg, respectively. The multivariate analysis showed that body weight, C3, and C3 /isoniazid dose were found to be significantly different between the 2 acetylation groups. In the pediatric group, only 9 had a C3 value within the target range, and all of them were RAs. The irrevocable interest of isoniazid TDM has been shown in Tunisian patients with tuberculosis, in both adult and pediatric patients, as isoniazid demonstrates an unpredictable pharmacokinetic profile.

Tigecycline is a broad-spectrum antibiotic with activity against multidrug-resistant (MDR) bacteria. It has limited indications. Studies are necessary to elaborate new guidelines. Here we report a case of postoperative MDR Acinetobacter baumannii meningitis treated by tigecycline combined with colimycin for 21 days. The treatment was well tolerated with a favourable outcome. In conclusion, tigecycline was shown to be effective in a case of MDR A. baumannii meningitis.
