Perniosis is not rare in children, but patients with secondary perniosis are more likely to be older. In terms of underlying systemic disorder, advanced age and male gender may be important demographic features. Measurement of cryoglobulin levels in the initial laboratory investigations of patients with perniosis is not necessary. Persistence beyond the cold seasons, and presence of photosensitivity, hypergammaglobulinaemia and rheumatoid factor may be useful in differentiating between idiopathic and secondary perniosis.

Background and Design:Current studies link vitamin D deficiency with many autoimmune diseases. Alopecia areata (AA) is a common autoimmune dermatological disease. The aim of this study was to investigate the relationship between vitamin D levels and alopecia areata. Materials and Methods: 25-hydroxyvitamin D [25(OH)D] levels in 40 patients with alopecia areata and age, gender and skin phototypematched healthy controls were evaluated. Serum 25(OH)D levels were measured in all subjects and grouped as normal/sufficient (>30 ng/ml), insufficient (15-30 ng/ml) and deficient (<15 ng/ml). Results: Both the study and control groups were composed of 21 females and 19 males. The mean age was 31.23±7.34 (21-50) and 30. 58±7.19 (21-48), respectively. In the study group, 2.5% of patients (n=1) had normal, 15% (n=6) insufficient and 82.5% (n=33) of patients had deficient 25(OH)D levels. In the control group, 2.5% (n=1) of patients had normal, 25% (n=10) insufficient and 72.5% (n=29) of patients had deficient 25(OH)D levels. There was no statistically significant difference between the groups (p>0.05). In both groups 97.5% of patients had 25(OH)D levels below the normal range. Conclusion: Vitamin D levels in patients with AA were similar to those in the controls. This similarity may suggest that there is no relationship between vitamin D and AA. However, it may also indicate that the relationship between AA and Vitamin D is not via the level but vitamin D receptor (number and/or structure). (Turkderm 2015; 49: 50-3)

Slow-healing wounds contain insufficient amounts of intrinsic collagenases to provide sufficient wound debridement, so that the use of products containing synergistic collagenases and proteases may be helpful. We report the successful use of collagenase clostridipeptidase A in two newborns, a premature infant with 3rd degree burns, and a term neonate with an extravasation necrosis caused by calcium gluconate. Surgical excision of necrotic tissue is a serious intervention and prolongs the duration of hospitalization. Enzymatic eschar removal may have an advantage over surgery especially in newborns with a high risk for surgery, with its possible complications, need for anesthesia, and perhaps for blood transfusion.
