Alterations of irisin concentrations in saliva and serum of obese and normal-weight subjects, before and after 45 min of a Turkish bath or running

The purpose of this study was to ascertain (1) whether human saliva contains irisin and whether its level correlates with serum irisin concentration, (2) whether salivary glands, eccrine glands and sebaceous glands in human skin produce irisin, (3) how the changes in saliva and serum irisin concentrations after the Turkish bath at 47 ± 3°C compare with the changes caused by moderate exercise in obese and normal weight subjects. Seven obese male subjects and seven normal weight subjects were enrolled for Turkish bath. Seven obese male subjects and seven normal weight subjects were also enrolled for moderate outdoor exercise, and thirteen male normal weight subjects neither exercised nor showered at the Turkish bath. From each participant, 1.5 ml of saliva and 5 ml blood were collected simultaneously before and after the moderate exercise and Turkish bath. Salivary glands and eccrine and sebaceous glands in the skin were screened immunohistochemically for irisin while serum and saliva irisin were measured with an ELISA. Submandibular glands, eccrine glands and sebaceous glands in the human skin showed strong irisin immunoreactivity. Human saliva contained irisin and its level was significantly higher than the serum levels in both obese and normal weight subjects. However, irisin concentrations were more markedly increased in both saliva and serum samples from subjects who had showered at a Turkish bath than in obese subjects who had exercised or in normal weight subjects. Human submandibular glands, eccrine sweat glands and sebaceous glands synthesize irisin.

Sporotrichosis Successfully Treated with Terbinafine and Potassium Iodide: Case Report and Review of the Literature

Sporotrichosis is rare in Turkey. We report a 40-year-old woman who had subcutaneous sporotrichosis caused by sporothrix schenckii that was successfully treated with terbinafine (250 mg, twice a day) for a period of 6 months. She received a saturated solution of potassium iodide orally for two months. Terbinafine and potassium iodide are suggested to be the agents of choice for treatment of subcutaneous sporotrichosis.

Does autonomic dysfunction play a role in atopic dermatitis

Background  Atopic dermatitis (AD) is a chronic dermatitis characterized by intense itching and excessive skin dryness. The factor most commonly blamed for the pathogenesis of skin dryness in the disease is impaired barrier function of the stratum corneum. However, there are findings indicating that the autonomic nervous system, and the sympathetic nervous system in particular, is affected negatively in AD, and thus, autonomic dysfunction can be an important factor leading to skin dryness.

Pimecrolimus 1% cream, methylprednisolone aceponate 0.1% cream and metronidazole 0.75% gel in the treatment of seborrhoeic dermatitis: A randomized clinical study

Background: Seborrhoeic dermatitis is a common, chronic, papulosquamous dermatosis. Treatment of seborrhoeic dermatitis includes topical treatments such as corticosteroids, antifungals, metronidazole and pimecrolimus. Objective: This study aimed to compare and contrast the efficacy and tolerability of pimecrolimus cream 1%, methylprednisolone aceponate 0.1% cream and metronidazole 0.75% gel topical treatments in the treatment of facial seborrhoeic dermatitis. Methods: The study included a total of 64 (32 males and 32 females) consecutive patients with facial seborrhoeic dermatitis. Patients were randomized into three equal groups. One group applied pimecrolimus 1% cream, another group applied methylprednisolone aceponate 0.1% cream, and the third group applied metronidazole 0.75% gel to their facial lesions twice daily for 8 weeks. Assessment of the disease severity was performed at baseline and at weeks 2, 4, and 8. Clinical measures assessed were erythema, scaling and pruritus, which were evaluated using a four-point scale (0–3). Results: Of the 64 patients, 17 (80%) in the metronidazole group, 21 (100%) in the pimecrolimus group and 22 (100%) in the methylprednisolone aceponate group completed the study. Four patients in the metronidazole group left the study. All of the therapeutic agents were found to be effective; however, the efficacy of pimecrolimus was higher than those of metronidazole and methylprednisolone (p < 0.05). When side effects associated with pimecrolimus and metronidazole were compared, the latter was found to be associated with more side effects (p < 0.05). Conclusions: We suggest pimecrolimus to be a therapeutic option for seborrhoeic dermatitis cases that show an unfavourable response to methylprednisolone aceponate.

Dermatology life quality index scores in children with vitiligo: comparison with atopic dermatitis and healthy control subjects

Vitiligo and atopic dermatitis (AD) are two major cutaneous diseases that affect quality of life (QoL) by causing functional and psychosocial disorders. Our objective was to calculate Children’s Dermatology Life Quality Index (CDLQI) scores in children with vitiligo and to compare these values with those in AD patients and healthy control subjects. The CDLQI was completed for 50 vitiligo and 50 AD patients presenting at the dermatology polyclinic, as well as for 50 age‐ and sex‐matched healthy controls. All subgroups in the vitiligo patient group had significantly higher total CDLQI scores than healthy controls. Vitiligo patients were found to have increased scores on all parameters, except itch, clothes/shoes, and sleep, compared with the AD patient group. Scores on itch and sleep were significantly higher in the AD group than in the vitiligo patients. Quality of life in children with vitiligo is substantially lower than in children with AD. This decline in QoL is critical in the psychosocial development of the former group.

The comparison of treatment with clobetasol propionate 0.05% and topical pimecrolimus 1% treatment in the treatment of alopecia areata

Abstract Background: Alopecia areata (AA) is a non-scarring hair loss. Objective: We aimed the comparison of clobetasol propionate and pimecrolimus efficiency and tolerability in the treatment of AA. Methods: The study included a total of 100 consecutive patients with AA. Patients were randomized into four groups. 30 patients used 1% pimecrolimus cream, 30 patients used 0.05% clobetasol propionate cream, 20 patients used petrolatum as placebo. Scalp of 20 patients was divided into two equal areas and one area was treated with 1% pimecrolimus cream and the other area with 0.05% clobetasol propionate cream. Results: At week 12 of treatment, the recovery rate of the pimecrolimus group was 53.73 ± 44.49 and the recovery score was 3.63 ± 2.07; that of the clobetasol propionate group was 47.00 ± 44.80 and the recovery score was 3.33 ± 2.20; that of the placebo group was 35.50 ± 40.53 and the recovery score was 2.75 ± 1.88. There was no statistically significant difference among the groups in terms of the percentage of recovery and the recovery score (p < 0.05). Conclusion: In conclusion, we detected that topical pimecrolimus treatment is as effective as topical corticosteroids and is superior to topical corticosteroids in terms of side effects in the treatment of AA.

Treatment and follow-up of persistent granulomatous cheilitis with intralesional steroid and metronidazole

Granulomatous cheilitis (GC) is a chronic edema which frequently affects the upper lip due to granulomatous inflammation. Its etiology is currently unknown. This rare disease is generally accompanied by Melkersson–Rosenthal syndrome (MRS), characterized by scrotal tongue, orofacial edema and facial paralysis. However, it is also known to develop only with orofacial edema. Granulomatous cheilitis is a difficult disease to treat because of recurrences. There are contradictory reports about the results of treatment without surgical intervention and the rates of recurrence. Our case was a 57‐year‐old female patient who was characterized by orofacial edema only. The edema and erythema had persisted for 1 year before admission. In the present case, application of intralesional corticosteroid treatment as a total of three injections over 3 consecutive months (one injection per month) and the accompanying metronidazole treatment brought about successful results. No recurrence was observed in the follow‐up.

Vitamin levels in Behcet's disease

Objective: To determine the role of oxidative stress and the antioxidant defense mechanism in the etiopathogenesis of active and inactive Behçets disease. In line with this objective, the present study aimed to examine the levels of nitric oxide (NO) and malondialdehyde (MDA), which are the end products of oxidant stress, and vitamins, which are non‐enzymatic antioxidants, for the diagnosis and particularly the follow‐up of Behçets disease. Materials and methods: The study group consisted of a total of 60 individuals: 40 of whom were Behçets disease patients and 20 were healthy individuals. Of the 40 Behçets patients, 29 had the active and 11 had the inactive (stable) form of the disease. Results: Although plasma MDA and NO (its stable form nitrite) levels in the total patient group were statistically significantly higher than those in the control group (p<0.06), there was no statistically significant difference as such between inactive Behçets patients and the control group (p>0.05). Vitamin E, C, B1, B2 and flavin mononucleotide (FMN) values were significantly lower in the patient group in comparison with the control group (p<0.05). There was no statistically significant difference in other vitamin values. Discussion: It is contemplated that measurement of such oxidative stress factors as MDA and NO and an accompanying evaluation of the antioxidant defense system can be significant in the diagnosis and treatment follow‐up of Behçets disease.

Increased frequency of restless legs syndrome in atopic dermatitis.

Background.  Restless legs syndrome (RLS) is characterized by an unpleasant sensation in the legs, which is difficult to describe, but produces an urge to move the legs frequently.

Effect of Oral Isotretinoin Treatment on Retinal Nerve Fiber Layer Thickness

Background: Oral isotretinoin treatment can cause ocular side effects. Objective: This study was performed to detect possible toxic effects of oral isotretinoin treatment on the retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL). Methods: The study population consisted of 54 eyes of 27 patients with nodulocystic acne who used oral isotretinoin (Roaccutane) treatment. Macular GCL and peripapillary RNFL thickness measurements were performed using spectral domain optical coherence tomography (OCT) before and after therapy. Results: Before and after treatment, a complete ophthalmologic examination was normal in all eyes. However, posttreatment lower temporal (TL) values were significantly lower (76.80 ± 16.31) than pretreatment TL values (84.96 ± 24.83) (p = .02). There was no statistically significant difference in the other OCT values, upper temporal, superotemporal, superonasal, upper nasal, lower nasal, inferonasal, and inferotemporal (p = .35, p = .40, p = .56, p = .95, p = .94, p = .93, p = .61, respectively). Also, there was no statistically significant difference between the right and left eyes and between genders for all parameters (p > .05). Conclusion: The use of oral isotretinoin treatment has increased in recent years. In addition, oral isotretinoin treatment has a broad adverse effect potential on the ocular system. The measurement of RNFL thickness, especially TL thickness, by OCT may be useful for detecting the possible toxic effect of oral isotretinoin therapy on RNFL.
