Multicenter study evaluating the impact of COVID-19 outbreak on dermatology outpatients in Turkey.

COVID-19 pandemic has a significant impact on public health, whether directly or indirectly. The first case was seen in Turkey on March 11, and the World Health Organization (WHO) declared a pandemic on March 12, 2020. The study aimed to document the effect of pandemic on dermatology outpatient clinics in Turkey. Fifteen tertiary hospitals from 13 provinces were included in the study, which was conducted between January 12 and May 12, 2020. The International Codes of Diseases (ICD-10) categories and patients' characteristics were evaluated before and after the pandemic. A total of 164 878 patients, 133 131 before and 31 747 after the pandemic, were evaluated. The daily hospital applications were found reduced by 77%. The three of the most frequent diagnoses; dermatitis, acne, and psoriasis remained unchanged after the pandemic. While the frequency of herpes zoster, scabies, urticaria, pityriasis rosea and sexually transmitted diseases increased significantly; allergic and irritant contact dermatitis decreased after the pandemic. The applications regarding cutaneous neoplasms were considerably reduced during the pandemic, and this effect was more pronounced in cities with higher COVID incidence. The pandemic caused a noteworthy reduction in the number of patients accessing dermatological care. The pandemic caused significant changes in the frequency of a wide range of dermatological diseases. The application of cutaneous neoplasms is considerably reduced after the pandemic, and this effect was more pronounced in cities where pandemics are frequent. Therefore, the pandemic has resulted on numerous impacts on many critical issues in dermatology and dermatological care.

Anterior cervical hypertrichosis: a sporadic case.

Anterior cervical hypertrichosis is a very rare form of primary localized hypertrichosis. It consists of a tuft of terminal hair on the anterior neck just above the laryngeal prominence. The etiology is still unknown. In this article, we reported a 15-year-old female patient who presented to our clinic with a complaint of hypertrichosis on the anterior aspect of the neck for the last five years. Her past medical history revealed no pathology except for vesicoureteral reflux. On the basis of clinical presentation, our patient was diagnosed with anterior cervical hypertrichosis and she was considered to be a sporadic case due to lack of other similar cases in familial history. To date, 33 patients with anterior cervical hypertrichosis have been reported. Anterior cervical hypertrichosis can be associated with other abnormalities, but it frequently presents as an isolated defect (70%). The association of vesicoureteral reflux and anterior cervical hypertrichosis which was observed in our patient might be coincidental. So far, no case of anterior cervical hypertrichosis associated with vesicoureteral reflux has been reported in the literature.

Angiolipoleiomyoma located in the earlobe.

Angiolipoleiomyoma (ALLM) is a solid tumor that is mostly derived from muscle tissue. It is often located in the kidneys of patients with tuberous sclerosis; ALLMs located outside the kidneys are very rare. Among the rare presentations are cutaneous ALLMs, which manifest as 1- to 4-cm asymptomatic, acquired, solitary, subcutaneous nodules that have a strong predilection for males. To the best of our knowledge, only 22 cases of ALLM of the skin have been previously reported in the literature; in 5 of these cases, the tumor was located on the ear. Histologically, tumoral proliferation is observed with smooth muscle, fat tissue, and vascular channels surrounded by a fibrous capsule; cellular atypia is not observed. We report the case of a 67-year-old man who presented for evaluation of a purplish nodular lesion that had been present on his right earlobe for 10 years. Analysis of an excisional biopsy specimen revealed a nodular formation that consisted mostly of thick-walled veins within a fibromyxoid stroma; smooth-muscle tissue and fat globules were observed in places. The lesion was diagnosed as a cutaneous ALLM.

Clinical and pathological features of 31 cases of lipedematous scalp and lipedematous alopecia.

Little is known about lipedematous scalp (LS) and lipedematous alopecia (LA). We investigated the clinical and histopathological features of LS and LA with a 7-year retrospective re-evaluation of 31 patients. 23 cases were LS and 8 LA, with 25 females and 6 males. The overweight and obese groups contained 15 patients with 16 within the normal weight range. Scalp thickness varied between 9-18 mm in our patients by magnetic resonance imaging. Thickening of the subcutaneous adipose tissue layer was present in all cases. Dermal edema was seen in 22 patients, lymphatic dilatation in 17 and elastic fiber fragmentation in 21. When the relationship between dermal edema and elastic fibers was investigated, elastic fiber fragmentation was found in 86.4% of cases with dermal edema. Collagen fragmentation and coarsening were seen in two cases, and collagen was normal in 24 cases. The number of follicles was decreased in 9 cases and normal in 17. The clinical and histopathological findings were not statistically different between LS and LA groups (p>0.05). The majority of the patients in our study were females, suggesting an underlying hormonal pathology. The association with obesity suggested that anatomical differences can be present in lipid distribution. Dermal edema and lymphatic dilatation suggested the primary pathology is lymphatic system.

Evaluation of microbiological spectrum and risk factors of cellulitis in hospitalized patients.

BACKGROUND AND DESIGN: Cellulitis is a common soft tissue infection and the severity of disease vary from mild to life threatening. The aim of the present retrospective study was to evaluate age, sex, site of infection, microbiological spectrum and the risk factors of cellulitis in hospitalized patients. MATERIALS AND METHODS: The data were retrospectively obtained by the review of 185 hospitalized patients who were diagnosed as cellulitis between 2003 and 2009 in the departments of dermatology, infectious diseases, internal medicine and surgery clinics of Haydarpasa Numune Training and Research Hospital (Istanbul, Turkey). The diagnosis was done by infectious diseases and dermatology specialists in all patients who were included to this study. Demographic findings, wound-blood cultures and risk factors of the patients with cellulitis were evaluated. RESULTS: Eighty-six were female, 99 were male of total 185 patients, and the mean age of them was 48 ± 27 (14-85). The leg was the involved site in 69% of the patients. The most frequent isolated bacteria from wound cultures were methicillin-sensitive Staphylococcus aureus 31.5%, Pseudomonas aeruginosa 12.6%, and Escherichia coli 12.3%. However, methicillin-sensitive S. aureus 32.5%, methicillin-resistant S. aureus 22.5%, coagulase-negative staphylococci 17.5% were detected from blood cultures. There was not any underlying risk factor in 104 (55.3%) patients. The risk factors observed in the other 81 patients were previous surgery or open wound 29 (35.8%), diabetes mellitus 19 (26.6%), cardiovascular diseases 16 (19.7%), immunosuppression 11 (13.5%), lymphoedema 6 (7.4%). CONCLUSION: In the patients hospitalized for cellulitis, the most frequently isolated microorganism from the wound and blood cultures was S. aureus and the most frequently detected risk factors were to have an open wound and previous surgery. Especially when the patients had risk factors, it was observed that the bacterial spectrum was broader and the clinical presentation was severe. The wound and blood cultures should be performed simultaneously for the microbiological diagnosis and the appropriate management of cellulitis.

A case of lichen sclerosus et atrophicus accompanying bullous morphea.

Bullous morphea is a rare form of morphea characterized with bullae on or around atrophic morphea plaques. Whereas lichen sclerosus et atrophicus (LSA) is a disease the etiology of which is not fully known, and which is characterized with sclerosis. Coexistence of morphea and LSA has been identified in some cases. Some authors believe that these two diseases are different manifestations which are on the same spectrum. The 70-year-old patient stated herein, presented to us for 6 months with annular, atrophic plaques, ivory color in the middle, surrounded by living erythema, on the front and back of the trunk. Occasionally bulla formation on the plaques on the trunk lateral was identified. Fibrotic and atrophic plaques of ligneous hardness were present on the front side of tibia of both legs. In the histopathologic examination, the lesions were found concordant with bullous morphea and LSA. With colchicine 1.5 mg/day, pentoxifylline 1,200 mg/day, topical calcipotriol ointment and clobetasol propionate cream, the erythema in the patient's lesions faded and softening in the fibrotic plaques was observed. Concomitance of bullous morphea and LSA is a rarely seen, interesting coexistence which suggests a common, as yet unknown, underlying pathogenesis.

Efficacy of 1% terbinafine cream in comparison with 0.75% metronidazole gel for the treatment of papulopustular rosacea.

BACKGROUND: Topical antifungals comprising imidazole derivatives have been used for the treatment of rosacea previously, owing to their anti-inflammatory activities. Terbinafine, an antifungal agent belongs to allylamine group, has also anti-inflammatory effects. Currently, there are only a few unpublished studies, in which terbinafine has been used systemically for rosacea treatment. AIMS: In this single-blind, 8-week study, we investigated the potential efficacy and safety of terbinafine 1% cream for the treatment of mild and moderate papulopustular rosacea, and compared the results with those of 0.75% metronidazole gel. PATIENTS/METHODS: Forty patients, 30 females and 10 males, with papulopustular rosacea were enrolled into the study between 2006 and 2007 years. Twenty of the patients were instructed to apply 1% terbinafine cream, whereas others patients of the study population were instructed to use 0.75% metronidazole gel. A total of 32 patients completed the study. Pre-treatment and post-treatment total severity score (TSS) of the disease were determined by assessing the severity of erythema/telangiectasia, and the number of papules/pustules of the whole face. The overall response rates, differences of pre-/post-treatment scores of each criterium and the percentages of the decrease in TSS of the study groups were compared statistically. RESULTS: There was no statistically significant difference between the groups in terms of age, sex, and disease duration (P = 0.937, 1.000, and 0.055, respectively). No significant difference was found between the mean post-treatment TSSs of the two groups (P = 0.605). The percentage of clearance assessed by the differences between pre-treatment and post-treatment TSSs was 55% in terbinafine group, although the percentage was 45% in metronidazole group, with no statistically significant difference between the groups (P = 0.496). Local side effects including erythema, pruritus, and burning were mild and transient in both groups, with similar frequencies (P = 0.101). CONCLUSION: This preliminary study suggests that 1% terbinafine cream is an effective and safe treatment for papulopustular rosacea, and can be an option for patients who cannot tolerate other modalities.

Generalized papular and sclerodermoid eruption: scleromyxedema.

Scleromyxedema (SM) is a rare chronic progressive and highly intractable cutaneous disease with unknown etiology, affecting both genders equally between 30 and 50 years. The disease is characterized with mucin deposits in the skin and/or other organs. In fact it is a clinicopathological subset of lichen myxedematosus (LM) according to a new classification. Sclerodermiform plaques and lichenoid papules are characteristic cutaneous lesions. An elevation of IgG λ (lambda) chain exists in most cases and extracutaneous involvement occurring with variable systemic findings is also detected. Generalized form is quite difficult to treat and may even be fatal. Herein, we present a male patient with typical features of generalized papular and sclerodermoid LM variety and with benign outcome by isotretinoin.

Ross syndrome: Unilateral hyperhidrosis, Adie's tonic pupils and diffuse areflexia.

Ross syndrome is a rare disorder first described in 1958 with partial autonomic dysfunction. It has three basic components including unilateral or bilateral segmental anhidrosis, Adie's tonic pupils and areflexia or hyporeflexia of deep tendon reflexes. The most disturbing symptom in the patients is segmental compensatory hyperhidrosis and often the hypohidrosis or anhidrosis is not even noticed. While the pathogenesis of Ross syndrome is unclear, degenerative changes or damage to the peripheral autonomic nerve system or dorsal root ganglia have been suggested as possible causes. About 50 cases have been reported, usually by neurologists and ophthalmologists, and less often by dermatologists. We present a 26-year-old patient who displayed the classic triad of this syndrome, emphasizing that the presenting complaint may be hyperhidrosis and that multidisciplinary evaluation in neurology and ophthalmology is essential.

Treatment of focal epithelial hyperplasia with topical imiquimod: report of three cases.

Focal epithelial hyperplasia (Heck disease) is a rare disorder caused by specific types of HPV. It mainly involves oral mucosa and children are affected more frequently. It may persist for years, producing a significant reduction in quality of life. Several treatment modalities such as surgical excision, laser ablation, cryotherapy, electrocauterization, topical, intralesional, systemic interferon, and systemic retinoic acid have been used with inconsistent results and many side effects. Here we report three children of Turkish origin with focal epithelial hyperplasia successfully treated with imiquimod 5% cream. No serious side effects were observed and recurrence did not occur during the 1-year follow-up period.

Is there a link between nickel allergy and coronary stent restenosis?

Although many patients with coronary artery disease are being treated by coronary stents, in-stent restenosis is the major limitation of percutaneous coronary stenting procedures. Most stents are made of stainless steel, and that, allergic reactions to nickel ions released from coronary stainless-steel stents may be one of the triggering mechanisms for in-stent restenosis. We aimed to evaluate the relationship between in-stent restenosis and nickel allergy in a prospective study. For this purpose, we applied epicutaneous patch test for nickel in 43 patients who had undergone elective intracoronary stent placement for stable angina pectoris in the day following stent placement and evaluated the presence of nickel allergy. Control angiography was performed at 6 months to determine in-stent restenosis. Three (6.9%) patients had allergic reaction to nickel and 16 (37%) patients had developed in-stent restenosis. One of the 3 patients with nickel allergy had diffuse in-stent restenosis and the others not. The present study therefore does not support the proposed relationship between nickel allergy and development of in-stent restenosis in patients having stainless steel stents. Large scale studies are needed to reach a final conclusion.
