ABSTRACT
OBJECTIVE: Olfactory training (OT) represents a therapeutic option for multiple etiologies of olfactory dysfunction (OD) that also benefits normosmic subjects. In this retrospective study, we report the effectiveness of OT and factors associated with relevant changes in olfactory function (OF) in large groups of normosmic participants and patients with OD, including a control group that performed no training. METHODS: This was a retrospective pooled analysis including 2 treatment cohorts of 8 previously published studies. Adult participants that either presented with the major complaint of quantitative OD or normosmic volunteers were recruited at various ENT clinics and received OT or no training. The outcome was based on changes in objective olfactory test scores after OT. RESULTS: A total of 601 patients with OD or normosmic subjects were included. OT was more effective compared to no training. No interaction was found between OT and OF. In multivariate analysis, higher baseline OF (adjusted odds ratio, aOR, 0.93) and posttraumatic (aOR, 0.29) or idiopathic OD (aOR, 0.18) compared to postinfectious causes were significantly associated with lower odds of relevant improvements in patients with OD receiving OT. Subgroup analysis of normosmic participants receiving OT further revealed a significant association of lower age and baseline olfactory function with improvements of overall OF. CONCLUSIONS: This study demonstrated that OT was more effective than no training in patients with various causes of OD. Additionally, baseline olfactory performance and etiology of OD were identified as important factors associated with relevant improvements after OT.

Acne vulgaris is a common inflammatory disorder of the skin. Oral antibiotics are known to be effective in its treatment. A randomized, investigator-blinded study was performed to compare the efficacy of azithromycin with doxycycline. Fifty-one patients were randomized to receive either azithromycin 500 mg/day on 3 consecutive days per week in the first, on 2 consecutive days per week in the second, and on 1 day per week in the third month. The other group was given doxycycline twice a day for the first month and once a day for the second and third months. Clinical assessment was made at baseline, at the end of first, second, third, and post-treatment first and second months. Side effects were recorded. Statistically significant improvement for the facial lesions were obtained with both drugs. Neither drug was shown to be more effective than the other. The beneficial effect continued until 2 months after treatment. In the azithromycin group three patients had diarrohea, while photosensitivity was seen in two patients using doxycycline. This study indicates that azithromycin is at least as effective as doxycycline in the treatment of acne.

Alkaptonuria is a rare autosomal recessive disorder of inborn errors of metabolism. It is characterised by the deposition of "ochronotic pigment" especially in connective tissue as a result of deficieny of the "homogentisic acid oxidase" enzyme which has a role in the catabolism of tyrosine and phenylalanine. A compound heterozygote alkaptonuria patient, with manifestations in adulthood, without infantile and childhood signs is presented. The described alkaptonuria mutations are reported for the first time in the Turkish population.
