[SAPHO syndrome]. / Síndrome SAPHO.

We report two cases, one 23 and one 27 year old man, with several years background of sternal and sternoclavicular joints pain, respectively. The laboratory tests were normal. Based on the clinical, radiologic and scintigraphic findings, SAPHO syndrome was diagnosed. Bone scintigraphy makes it possible to obtain a whole body scan in a single whole body scan, and can be used for differential diagnosis of other osteoarticular diseases and for evolutive control and therapeutic response.

Comparison of aceclofenac with piroxicam in the treatment of osteoarthritis.

A multicentre, double-blind, randomised, parallel group study was undertaken to investigate the efficacy and safety of aceclofenac (123 patients, 100 mg twice daily) in comparison to piroxicam (117 patients, 20 mg once daily and placebo once daily) in patients with osteoarthritis of the knee. The treatment period of two months was preceded by a washout period of one week duration. On completion of the study, patients in both aceclofenac and piroxicam-treated groups exhibited significant improvement in pain intensity and functional capacity of the affected knee, as represented by the Osteoarthritis Severity Index (OSI) (p < 0.0001 and p < 0.001 respectively). This was further substantiated following the patient's assessment of pain intensity using the Visual Analogue Scale (VAS), in which significant improvements were demonstrated at all time points for each treatment group (p < 0.001). Although both treatment groups showed a significant improvement in all investigator's clinical assessments (functional exploration of the knee, knee flexion and extension (EXT)), there were no significant differences between the groups. There was, however, a more rapid improvement in knee flexion in the aceclofenac group after 15 days of treatment. Both aceclofenac and piroxicam were well tolerated by patients, the most commonly reported adverse events being gastrointestinal, although their incidence was low. Only 24 patients on aceclofenac, as opposed to 33 on piroxicam complained of dyspepsia, epigastralgia and pyrosis. While 7 patients in each group were withdrawn because of adverse events, only one patient with piroxicam was withdrawn because of severe upper gastrointestinal bleeding. Twice as many reports of fecal blood loss were made in the piroxicam group in comparison to the aceclofenac group. In summary, this study confirms the therapeutic efficacy of aceclofenac and suggests that it is a well-tolerated alternative NSAID to piroxicam in the treatment of osteoarthritis.

[Intolerance to hydroxychloroquine marketed in Spain (Dolquine) in patients with autoimmune conditions]. / Intolerancia a la hidroxicloroquina comercializada en España (Dolquine) en pacientes con patología autoinmune.

BASIS: A significant proportion of our patients has described to have problems from tolerance to Dolquine, a new presentation of hydroxychloroquine recently marketed in Spain, compared to Plaquenil. The objective was to know the tolerability and the adverse effects of this new presentation. PATIENTS AND METHOD: A cross-sectional multicenter study on 133 patients treated with Dolquine was conducted. RESULTS: Of the 133 patients (87% women; average age [AA]: 32.9 [15.4] years) who received Dolquine during an average period of 6.7 (1.4) months, 32 patients (24%) described to have more problems with this drug in comparison with other antimalarial. The adverse effects experienced were: bitter taste (62.4%), difficulty in swallowing the tablet (13.5%), dyspepsia (9.8%), nausea (7.5%), vomiting (1.5%), pruritus (1.5%), diarrhea (0.7%), and instability feeling (0.7%). The presence of gastrointestinal adverse effects was not related to the consumption of gastroerosive drugs, gastric protectors, or a high number of drugs. The attrition rate was 9.8%. Conclusions. Dolquine induces lower tolerance and more gastrointestinal adverse effects than Plaquenil, pointing out its bitter taste and the difficulty in swallowing it. Despite this higher intolerance there was not an increase in the attition rate from the antimalarial treatment in comparison to other series.
