Importance of the C-Reactive Protein to Albumin Ratio in the Diagnosis and Prognosis of Mycosis Fungoides.

INTRODUCTION: The C-reactive protein to albumin ratio (CAR) lately has demonstrated as a prognostic factor and an indicator of disease activity, severity and prognosis in solid organ malignancies and inflammatory diseases. However, the effects of CAR have not been investigated in mycosis fungoides (MF) patients yet. OBJECTIVES: This study aimed to determine the potential role of CAR as a diagnostic and a prognostic indicator in MF. METHODS: We retrospectively investigated the electronic medical records of 97 patients with MF admitted to the Dermatology Clinic of Health Sciences University, Diskapi Yildirim Beyazit Training and Research Hospital between January 2014 and December 2020. In total, 60 patients with MF were enrolled in the study. CAR was evaluated, patient and control group. Also, the other clinicopathological factors including age, lactate dehydrogenase, stage of disease, beta-2-microglobulin levels, and sedimentation levels were evaluated. RESULTS: The median value of CAR was 0.85 (0.10-7.51) in the patient group, whereas it was 0.39 (0.0-1.11) in the control group (P < 0.001). Patients with disease progression (N = 16, 13M, 3 F) had a median value of CAR 0.84 (0.10-7.51) and the median value of CAR (N = 44) was 0.86 (0.12-4.57) in the group of patients with stable disease. The CAR value had no prognostic significance (P > 0.05). CONCLUSIONS: There is no association between the CAR and progression in the stage in MF patients. But the CAR is significantly higher in patients with MF than in the control group. The CAR can be a guide for us in cases where we have difficulty in diagnosing.

A Case of Circumscribed Palmar or Plantar Hypokeratosis and a Mini-review of the Literature.

ABSTRACT: Circumscribed palmar or plantar hypokeratosis (CPPH) is a new dermatologic disorder that firstly defined Pérez A et al in 2002. Since that time, further cases of CPPH have been reported by different authors in different countries. We report a 69-year-old Turkish woman who presented with asymptomatic, erythematous patches on the thenar region of the left hand and on the second left finger. Skin biopsy showed histological features of CPPH. In this article, it was emphasized that CPPH may be seen more frequently than expected and the clinical and pathological features of this disease with suspected malignant transformation should be known.

Drug-Induced Histiocytoid Sweet Syndrome: Two Cases With Levofloxacin and Amoxicillin-Clavulanate.

ABSTRACT: Histiocytoid Sweet syndrome (HSS) is an uncommon histologic variant of Sweet syndrome (SS). HSS can be distinguished from the classic SS with an infiltrate of histiocyte-like immature myeloid cells rather than dense neutrophilic infiltration, although the clinical features are similar. Previous studies have shown that the risk of hematologic malignancy is significantly higher in HSS compared with classic SS. To lesser extent, HSS is also associated with infections, inflammatory diseases, and drugs, particularly with antineoplastic agents as well. Here, we report a case of 2 patients with an abrupt onset of erythematous, tender plaques accompanied by fever, with that revealed similar histopathologic and immunohistochemical features, whom had a history of antibiotic use. Clinicopathologic correlation led to diagnosis of drug-induced HSS, associated with the use of levofloxacin and amoxicillin-clavulanate, respectively. Both patients were then successfully treated with systemic corticosteroid therapy, and neither of them had recurrence during the period of 24-month follow-up.

Secukinumab may be remedy for systemic amyloidosis findings secondary to hidradenitis suppurativa.

Hidradenitis suppurativa (HS) is a chronic relapsing inflammatory disease of follicular epithelium; many comorbidities occur that disrupt the quality of life of patients. Amyloidosis is one of them. We present a case with systemic amyloidosis secondary to HS and responding positively to secukinumab therapy. Secukinumab may also be an important option for amyloidosis findings in HS patients.

Systemic comorbidities associated with rosacea: a multicentric retrospective observational study.

BACKGROUND: Once considered a disorder limited to the skin, rosacea is now known to be associated with systemic disorders. The aim of this study was to determine what systemic comorbidities accompany rosacea and to determine the relationship between the type, severity, and duration of rosacea, and the presence of and type of systemic comorbidities. METHODS: This retrospective multicenter study was conducted by the Turkish Society of Dermatology Acne Study Group. Thirteen dermatology clinics throughout Turkey participated in the study. A structured physician-administered questionnaire was used to collect patient demographics, clinical findings, and lifestyle data. The principal rosacea subtype, physician global assessment of severity, and duration of rosacea were recorded. Physicians recorded each participant's medical history, including current and past comorbidities, duration of any such comorbidity, and the use of medications to treat any comorbidities. RESULTS: The study included 1,195 rosacea patients and 621 controls without rosacea aged 18-85 years. As compared to the controls, more of the rosacea patients had respiratory tract, gastrointestinal system, and metabolic and hepatobiliary system disorders in a rosacea's severity- and duration-dependent manner. CONCLUSION: Clinicians must be aware of the potential for systemic comorbidities in rosacea patients, which becomes more likely as disease duration and severity increase.

Comparison of quality of life in patients with androgenetic alopecia and alopecia areata

Abstract: Background: Androgenetic alopecia is one of the most common forms of hair loss. Alopecia areata is a common autoimmune disorder which causes hair loss. It has been previously reported that both alopecia disorders can have negative effects on quality of life. However, only a few studies have compared the effects of the two disorders. Objective: The aim is to show the impact of alopecia on patients' quality of life and compare patients with androgenetic alopecia and alopecia areata. Methods: 82 androgenetic alopecia and 56 alopecia areata patients were recruited. All patients were evaluated with the Hairdex scale and dermatology quality of life instrument in Turkish (TQL), and the scores were statistically compared according to age, sex, employment and education status, and severity of illness in the two groups. Also, female patients were statistically evaluated according to whether they wore headscarves. Results: Androgenetic alopecia patients had significantly higher total Hairdex scores in terms of emotions, functioning, and symptoms, while self-confidence was significantly higher in the alopecia areata patients. No significant differences were found in stigmatization or TQL scores between groups. The Hairdex scale and TQL scores did not show differences between the groups in terms of wearing headscarves. Study limitations: The validity and reliability of the Hairdex index have not been established in Turkey. Conclusions: Based on the Hairdex scale, our findings revealed that androgenetic alopecia patients are more affected by their disorder than alopecia areata patients. Although androgenetic alopecia is common and neither life-threatening nor painful, it is a stressful disorder with increased need for improvement in the patient's quality of life.

An overlap case of Parry-Romberg syndrome and en coup de sabre with striking ocular involvement and anti-double-stranded DNA positivity.

Parry-Romberg syndrome (PRS) may overlap localized scleroderma (morphea) lesions with linear depression (en coup de sabre [ECDS]). Overlap case with PRS and ECDS was presented. Enophthalmos, uveitis, ocular torticollis, keratic linear precipitates, and anti-double-stranded DNA positivity were identified. Subendothelial keratic precipitates detected by an in vivo laser scanning confocal microscopy were the first profiled in the literature. Patients must be evaluated and followed up carefully by their clinics to prevent misdiagnosis and unnecessary procedures such as surgery of ocular torticollis as muscular torticollis.

Long-Pulsed Nd: YAG Laser Treatment for Nail Psoriasis.

BACKGROUND: Psoriasis is a chronic inflammatory skin disease in which lesions display angiogenesis and increased vascularity. OBJECTIVE: The long-pulsed 1,064-nm neodymium:yttrium-aluminum-garnet (Nd:YAG) laser treats vascular lesions which suggests that it might also be used to treat nail psoriasis. METHODS: Sixteen patients (10 males and 6 females) with isolated nail psoriasis or nail with only mild cutaneous involvement were enrolled in the study. Nails were treated for 3 sessions with long-pulsed 1,064-nm Nd:YAG laser once monthly. During the course of the treatment, nail bed and matrix Nail Psoriasis Severity Index (NAPSI) scores were recorded. RESULTS: The mean baseline NAPSI score was 26 ± 7.2. The means of total NAPSI scores after the first, second, and third treatment sessions were as follows: 22 ± 6.6, 13 ± 6, and 5.7 ± 4.3, respectively. The decline in NAPSI score was statistically significant. At the end of the 3 treatment sessions, both nail bed and matrix lesions significantly responded to Nd:YAG laser treatment. CONCLUSION: The Nd:YAG laser is a promising treatment option for nail psoriasis.

Insulin resistance, diabetes mellitus and thyroid dysfunction in patients with palmoplantar pustulosis: a case-controlled study.

INTRODUCTION: Palmoplantar pustulosis (PPP) is a chronic pustular inflammatory skin disease; however, its pathogenesis is not well understood. Several factors, such as genetics, tobacco use and autoimmune issues, may contribute to this disease. AIM: This research was conducted to investigate the relationships between insulin resistance, thyroid disease and PPP. MATERIAL AND METHODS: Thirty-three patients with PPP and 27 age- and gender-matched controls were analysed for their smoking histories, thyroid function tests, anti-thyroid peroxidase antibody (anti-TPO) levels, fasting glucose, fasting insulin levels and the homeostatic model assessment (HOMA) index for insulin resistance. RESULTS: We found significant differences between the PPP and control groups according to their tobacco use and anti-TPO levels (p = 0.009 and p = 0.009, respectively). The proportion of tobacco use was 90% in the PPP patients and 63% in the controls. Gender and tobacco use were predictive risk factors for PPP in the multivariate analysis (OR = 141.7, p < 0.0001 and OR = 147.6, p = 0.006, respectively). An anti-TPO level > 35 U/ml and the presence of a thyroid abnormality were independent risk factors in the univariate, but not the multivariate analysis (OR = 4.2, p = 0.025 and OR = 5.4, p = 0.004, respectively). A moderate correlation between the gender and anti-TPO level was found (r = 0.361, p = 0.039); however, the fasting glucose, insulin and HOMA index were not significant between the PPP and control groups. CONCLUSIONS: Female gender and smoking were the most important risk factors for PPP; however, the increase in the anti-TPO level may be related to the predominance of females afflicted with this disease. Additional studies are necessary to clarify the relationships between PPP, thyroid disease and diabetes mellitus.

Increased Risk of Metabolic Syndrome in Patients with Vitiligo.

BACKGROUND: Inflammatory and immune processes can be triggered in vitiligo due to a decreased number of melanocytes and their anti-inflammatory effects. Because of the systemic nature of vitiligo, metabolic abnormalities such as insulin resistance and lipid profile disturbances as well as skin involvement may be observed in vitiligo. AIMS: To investigate the association between metabolic syndrome and vitiligo. STUDY DESIGN: Case-control study. METHODS: The demographic, clinical and laboratory features in the subjects were compared according to presence of vitiligo and metabolic syndrome [patients (n=63) vs. gender-age matched controls (n=65) and metabolic syndrome positive (n=38) vs. negative (n=90)]. A logistic regression analysis was also used. RESULTS: We identified metabolic syndrome in 24 (38.1%) subjects with vitiligo and 14 (21.5%) subjects without vitiligo (p=0.04). Active vitiligo, segmental vitiligo, an increased duration of vitiligo and an increased percentage in the affected body surface area were determined to be independent predictors of metabolic syndrome [activity of vitiligo: p=0.012, OR (95% CI)=64.4 (2.5-1672); type of vitiligo: p=0.007, OR (95% CI)=215.1 (4.3-10725.8); duration of vitiligo: p=0.03, OR (95% CI)=1.4 (1.1-2.0); percentage of affected body surface area: p=0.07, OR (95% CI)=1.2 (0.98-1.5)]. CONCLUSION: The risk of developing metabolic syndrome is increased in patients with vitiligo. The poor clinical features of vitiligo, such as active, extended and segmental vitiligo with an increased duration of time, are independent predictors for developing metabolic syndrome.

Evaluation of the Efficacy of Cryosurgery in Patients With Sebaceous Hyperplasia of the Face.

BACKGROUND: Cryosurgery is an effective treatment for sebaceous hyperplasia, but there have been few clinical studies. OBJECTIVES: The aim of this study was to evaluate the efficacy and safety of cryosurgery in the treatment of sebaceous hyperplasia. METHODS: Cryosurgery was performed 6 times, at 2-week intervals, with liquid nitrogen, and evaluated in 40 patients with 517 lesions ranging from 2 to 9 mm over the forehead, cheeks, and chin. All of the lesions were measured before and after the treatment. RESULTS: The mean age of the participants was 54.7 ± 8.9 years, and the male/female ratio was 21/19 (1.1). The mean time of the disease duration was 4.2 ± 3.0 years. After 6 cooling cycles, an excellent response (76%-100%) was seen in 341 patients (65.9%), a very good response (51%-75%) was seen in 102 (19.7%), a good response (26%-50%) was seen in 57 (11.1%), a poor response (1%-25%) was seen in 15 (2.9%), and no response (0%) was seen in 2 (0.4%). Age ( P = .004) and sex ( P < .0001) were independent predictors of an excellent response. The excellent response rates were 71.4% for males, 61.8% for females, 70.4% for ages older than 55 years, and 61.8% for ages younger than 55 years. Temporary hyperpigmentation was found in 5 lesions (0.96%), and recurrence was not seen at the 4-month follow-up. CONCLUSIONS: The well-aimed and controlled used of cryosurgery is an effective method for treating significant cosmetic disfigurement in patients with sebaceous hyperplasia. It is a low-cost therapy without scarring, hypopigmentation, or recurrence.

Cutaneous Side Effects of BRAF Inhibitors in Advanced Melanoma: Review of the Literature.

The incidence of melanoma has recently been increasing. BRAF mutations have been found in 40-60% of melanomas. The increased activity of BRAF V600E leads to the activation of downstream signaling through the mitogen-activated protein kinase (MAPK) pathway, which plays a key role as a regulator of cell growth, differentiation, and survival. The use of BRAF inhibitors in metastatic melanoma with BRAF mutation ensures clinical improvement of the disease. Vemurafenib and dabrafenib are two selective BRAF inhibitors approved by the Food and Drug Administration (FDA). Both drugs are well tolerated and successfully used in clinical practice. However, some adverse reactions have been reported in patients in the course of treatment. Cutaneous side effects are the most common adverse events among them with a broad spectrum. Both the case reports and several original clinical trials reported cutaneous reactions during the treatment with BRAF inhibitors. In this review, the common cutaneous side effects of BRAF inhibitors in the treatment of metastatic melanoma with BRAF V600E mutation were reviewed.

Serological test results of sexually transmitted diseases in patients with condyloma acuminata.

INTRODUCTION: Human papillomavirus (HPV) is one of the most common causes of sexually transmitted diseases (STD). The incidence of condyloma acuminata (CA) has increased in recent years. AIM: To determine demographical features and serological test results of STD in patients with CA. MATERIAL AND METHODS: A cross-sectional survey was conducted on 94 patients presenting to a dermatology clinic in Ankara, Middle Anatolia, Turkey. Dermatological examinations were made and the patients completed a questionnaire which consisted of questions about their marital status, partners and condom use. In all cases, VDRL/RPR, anti-HIV, HBsAg, anti-HCV and in 57 cases - HSV type 1-2 IgM and IgG were studied. If the value of VDRL or RPR was positive, TPHA was conducted. RESULTS: In our study, 83 men and 11 women had CA. We could not analyze whether our cases had multiple partners and a habit of condom use as some of the patients did not answer questions about their sexual life. We observed VDRL and TPHA positivity in 3 (3.1%) cases, none of those cases had clinical findings of syphilis and they denied using any therapy for syphilis. HBsAg positivity was found in 3 cases. No anti-HIV and anti-HCV antibody positivity was detected. CONCLUSIONS: The seroprevalence of HBsAg in our study was similar to that of the general population of Turkey. But as we found positive syphilis serology in 3 patients, we suggest that syphilis serology should be investigated in patients with CA.

Serum levels of homocysteine, folate and vitamin B12 in patients with vitiligo before and after treatment with narrow band ultraviolet B phototherapy and in a group of controls.

The association between vitamin B12, folate, homocysteine and vitiligo were studied in several studies, but the results are contradictory. Narrow-band ultraviolet B (NBUVB) phototherapy is now considered as a gold standard for the treatment of diffuse vitiligo. The effects of NBUVB phototherapy on both vitamin B12, folate and homocysteine levels have not been studied in vitiligo patients yet. Serum levels of vitamin B12, folate and homocysteine were measured in vitiligo patients and control group and also both before and after NBUVB phototherapy in vitiligo patients. While levels of homocysteine in patients with vitiligo were significantly higher than controls (16.9±8.4 vs. 10. 9±3.4 µmol/L; p<0,001) vitamin B12 and folate levels were not different (p>0.05). NBUVB phototherapy led to a 33.7±21.9% (0-75%) response in patients with vitiligo after 80 seccions. Treatment with NBUVB improved vitiligo and decreased serum levels of vitamin B12 (375±151 vs. 346±119 pg/ml, p=0.024), while serum levels of folate and homocysteine did not change significantly after treatment (p=0.914, p=0.127). Further studies are needed to clarify the influence of NBUVB phototherapy on folate, vitamin B12 and homocysteine levels in patients with vitiligo. Furthermore, studies with the analysis of skin levels of homocysteine rather than circulating levels may be useful to elucidate the effects of phototherapy on homocysteine levels.

Symmetrical drug-related intertriginous and flexural exanthema (Baboon syndrome) associated with infliximab.

BACKGROUND: Symmetrical drug related intertriginous and flexural exanthema (SDRIFE or Baboon syndrome) is a symmetrical contact dermatitis on inverse regions of the body. The disorder is easily differentiated from other drug eruptions by its typical appearance and lack of other concurrent findings. OBSERVATION: A 50-year-old male patient presented to our clinic complaining of a rash that had developed two days after the tenth infliximab infusion for psoriasis and reoccurred after consecutive infusions. The physical examination revealed a bilateral intergluteal, inguinal, abdominal, axillary, antecubital and neck region macular erythematous rash. There were no other systemic findings. The laboratory values were within normal range. The patient was diagnosed with symmetrical drug-related intertriginous and flexural exanthema associated with infliximab treatment based on dermatological findings, histopathology and the results of the provocation test. The lesions resolved permanently after the patient was swiched from infliximab to adalimumab. CONCLUSION: Various cutaneous adverse events of anti-tumor necrosis factor alpha treatment have already been reported. The increased use of these agents can lead to a wider variety of drug-induced skin lesions, such as the reported Baboon syndrome.

A case of pachyonychia congenita with unusual manifestations: an unusual type or a new syndrome?

A 30-year-old man presented with lesions on his oral mucosa and soles. There were no similar complaints in his family members. The dermatological examination revealed follicular hyperkeratosis on his trunk and upper extremities and flesh-colored, firm cystic lesions on his axillae. He had focal, painful, hyperkeratotic areas sited particularly on both his soles and palms. In addition to these, leukokeratosis and ulcerative areas on buccal, labial mucosa, tongue, and at corners of the mouth, and complete loss of teeth was observed. The proximal layering was revealed on all of his nails. The laboratory investigations produced normal results except the deficiency of immunoglobulin A. The psychiatric examination revealed mild mental retardation. Keratin gene (KRT6a, KRT6b, KRT16, and KRT17) mutations for pachyonychia congenita were negative. He got removable dental prosthesis because of inadequate alimentation. Squamous cell cancer developed on lower lip mucosa during follow-up. We present an individual who had different nail dystrophy, epidermal cysts, mental retardation, blepharitis, complete loss of teeth, and negative keratin gene mutations for pachyonychia congenita and developed squamous cell cancer on the oral leukokeratosis lesions. We think that the present case may be an unusual new type of pachyonychia congenita.
