Cutaneous findings in patients with acromegaly and its relationship with concomitant endocrinopathies.

OBJECTIVES: Skin changes in acromegaly are often the first sign of the disease. The aim of this study was to describe the cutaneous findings in patients with acromegaly. In addition, a secondary aim was to investigate the possible association of these findings with remission status and concomitant endocrinopathies. DESIGN, PATIENTS, AND MEASUREMENTS: In this prospective multicenter study, 278 patients over the age of 18 years with acromegaly who were followed up in 14 different tertiary healthcare institutions were included. These patients, who were followed up by the Endocrinology Department, were then referred to a dermatologist for dermatological examination. The frequency of skin lesions was investigated by detailed dermatologic examination. Dermatological diagnosis is reached by clinical, dermatological and/or dermoscopic examination, and rarely skin punch biopsy examinations in suspicious cases. The possible association of the skin findings between remitted and nonremitted patients and with concomitant endocrinopathies were evaluated. RESULTS: The most common skin findings in patients with acromegaly in our study were skin tags (52.5%), cherry angiomas (47.4%), seborrhoea (37%), varicose veins (33%), acneiform lesions (28.8%), hyperhidrosis (26.9%) and hypertrichosis (18.3%). Hypertrichosis was significantly more prevalent in patients nonremitted (p: .001), while xerosis cutis was significantly more prevalent in patients remitted (p: .001). The frequency of diabetes mellitus and hypothyroidism was significantly higher in patients with varicose veins and seborrhoeic keratosis than those without. Additionally, the coexistence of hypothyroidism, hyperthyroidism and galactorrhea was significantly higher in patients with Cherry angioma than in those without Cherry angioma (p-values: .024, .034 and .027, respectively). The frequency of hypogonadism in those with xerosis cutis was significantly higher than in those without (p: .035). CONCLUSIONS: Cutaneous androgenization findings such as skin tag, seborrhoea, acne and acanthosis nigricans are common in patients with acromegaly. Clinicians should be aware that skin findings associated with insulin resistance may develop in these patients. It can be said that the remission state in acromegaly has no curative effect on cutaneous findings. Only patients in remission were less likely to have hypertrichosis. This may allow earlier review of the follow-up and treatment of acromegaly patients presenting with complaints of hypertrichosis. Additionally, it can be said that patients with skin findings such as cherry angioma may be predisposed to a second endocrinopathy, especially hypothyroidism. Including dermatology in a multidisciplinary perspective in acromegaly patient management would be beneficial to detect cutaneous findings earlier.

A founder deletion in ECM1 of 1163 bp causes lipoid proteinosis in the southeast region of Turkiye.

Lipoid proteinosis (LP) is an inherited disorder characterized by the accumulation of hyaline-like material in the skin, oral cavity, and larynx. The primary symptoms include hoarseness, restricted tongue movements, and various skin lesions. LP is caused by biallelic pathogenic variants in the ECM1 gene. We studied 20 patients from nine different families with LP, 19 of whom are from Sanliurfa in the southeastern region of Turkiye. Overall, the clinical features of the patient cohort were consistent with those mentioned in the literature, except for one exhibited an atrophoderma vermiculatum-like lesion, which is atypical for LP. The clinical exome sequencing analysis revealed three different homozygous variants in the ECM1 gene (NM_004425). While c.1246C>T p.(Arg416*) on Exon 8 and c.806G>A p.(Cys269Tyr) on Exon 7 were detected in 1 patient each, an intragenic deletion of 1163 base-pairs including Exons 9 and 10 (c.1304 + 33_*300del) was identified in 18 patients from 7 unrelated families. The haplotype analysis of the deletion variant indicated a founder effect in the families from the Sanliurfa province of Turkiye. Based on all this information, copy number variation analysis is recommended for patients with LP. In addition to this rare observation, this study represents the largest examination of the molecular spectrum of LP patients in Turkiye, alongside the clinical spectrum.

Geriatric cutaneous leishmaniasis: a retrospective analysis of 622 cases.

BACKGROUND: Cutaneous leishmaniasis (CL) is most common in childhood because children are exposed to the parasite early and, unlike adults, do not have immunity to CL. Since CL is less common in geriatric patients, clinical and epidemiological data in this age group are limited. This study aims to compare the clinical and demographic characteristics of geriatric patients diagnosed with CL with young patients. METHODS: In this retrospective study, 622 patients aged 65 and over and 6350 patients aged 19-64, who applied to Sanliurfa Oriental Boil Diagnosis and Treatment Center between January 2013 and February 2024 and were diagnosed with CL by parasitological examination, were included. Clinical and demographic characteristics of patients diagnosed with CL, such as age, gender, location of the lesion, lesion size, duration of the lesion, and treatments applied due to the diagnosis of CL, were recorded. Clinical and demographic characteristics of geriatric and young patients were compared. RESULTS: The mean age of elderly CL cases was 72.95 ± 6.54 years, and 65.2% were female. The most common clinical forms were ulcers (51.9%) and plaques (41%), respectively, in young and elderly patients. The most common locations of the lesions were upper limbs (54.8%) in all patients. The most preferred treatment method was intralesional (IL) meglumine antimoniate (MA) treatment (98.3%) in all patients. There were no difference between young and elderly CL cases in terms of mean number of lesions, average lesion duration, average lesion size, lesion location, clinical forms of lesions, and treatments options (P > 0.05). CONCLUSIONS: Based on the results of our study, it can be said that the clinical and demographic characteristics of CL are similar in young and old patients and systemic MA treatment shows similar clinical benefit in both age groups. In addition, it can be said that systemic MA therapy can be used safely in young patients and elderly patients without contraindications. IL MA therapy can be used in elderly patients where systemic MA therapy is contraindicated.

Many faces of cutaneous leishmaniasis.

BACKGROUND: Our objective in this study is to determine the atypical clinical presentations of cutaneous leishmaniasis (CL) patients diagnosed in Sanliurfa province. METHODS: This retrospective study included 213 patients with atypical clinical presentations among 1751 patients diagnosed with CL between October 2019 and August 2022 in Sanliurfa Oriental Boil Diagnosis and Treatment Center located in an endemic region for CL. RESULTS: We found the prevalence of atypical CL to be 12.1%. The most common atypical lesions were lupoid 21 (9.8%), erysipeloid 16 (7.5%), impetiginous 16 (7.5%), recidivan 15 (7%), eczematous 15 (7%), ecthyma-like 13 (6.1%), pyoderma gangrenous-like 12 (5.6%), and sporotrichoid 12 (5.6%). Other lesions with atypical clinical presentations: chalazion-like, verrucous, dental sinus-like, psoriasiform, zosteriform, lymphoma-like, juvenile xanthogranuloma-like, volcano-like, paronychial, basal cell carcinoma-like, squamous cell carcinoma-like, herpes labialis-like, keratoacanthoma-like, chancriform, annular, lichenoid, mastocitoma-like, keloidal, epidermoid cyst-like, kaposi sarcoma-like, scar leishmaniasis, granulomatous cheilitis-like, mycetoma-like, molluscum contagiosum-like, discoid lupus erythematosus-like, and dermatofibroma-like. CONCLUSIONS: In addition to the atypical clinical presentations previously reported, we also defined dermatofibroma-like, Kaposi sarcoma-like, dental sinus-like, juvenile xanthogranuloma-like, mastocytoma-like, and epidermoid cyst-like. It should be kept in mind that CL can clinically mimic many infectious, inflammatory, and neoplastic diseases, which should be considered in the differential diagnosis of long-term non-healing lesions, especially in endemic areas. Key message What is already known on this subject:  CL is known as the great imitator disease in dermatology. What this study adds:  In addition to the atypical clinical presentations previously reported, we also defined dermatofibroma-like, Kaposi sarcoma-like, dental sinus-like, juvenile xanthogranuloma-like, mastocytoma-like, and epidermoid cyst-like. How this study might affect research, practice, or policy:  CL can clinically mimic many infectious, inflammatory and neoplastic diseases, which should be considered in the differential diagnosis of long-term non-healing lesions, especially in endemic areas.

Evaluation of Clinical and Oral Findings in Patients with Epidermolysis bullosa.

Introduction: Epidermolysis bullosa (EB) is a genetically inherited disease characterized by recurrent bullae and erosions on the skin with numerous signs of dental caries and poor oral hygiene. The aim of this study was to investigate the general clinical and oral findings of patients with EB. Materials and Methods: In this prospective study, the clinical and oral findings and family history of 26 cases with EB were evaluated. The type of EB, gender, age, parental consanguinity, dental caries, oral findings, distribution of lesions and presence of associated anomalies, clinical and oral findings correlated with gender were recorded. Results: All 26 patients with EB had a history of consanguinity and siblings with EB to varying degrees. In our study, malnutrition, anemia and growth retardation, gastrointestinal system complications, hair thinning, hand and nail deformity, ocular problems and renal disease (in one case) were observed with variable frequencies. When the intraoral findings of the patients were investigated, extensive dental caries in all EB types, enamel hypoplasia in junctional EB (JEB) and the presence of tooth-root to be extracted in dystrophic EB (DEB), intraoral bullae and lesions, ankyloglossia, vestibular sulcus insufficiency, microstomia and maxillary atrophy were observed. Three cases had restorative treatment and one case had prosthetic rehabilitation. Conclusions: Oral involvement can be seen with varying frequencies depending on the type of EB and the severity of the disease. It may result from delayed oral and dental rehabilitation due to physical disabilities, limitations and more pressing medical problems. Microstomy, pain from mucosal lesions, and restricted access to the mouth can be caused by poor oral hygiene. Oral complications and caloric needs of individuals with EB should be determined, and individual prophylaxis should be applied to prevent caries formation and protect teeth.

Evaluation of choroidal thickness and ocular manifestations in lipoid proteinosis.

PURPOSE: To assess choroidal thickness in patients with lipoid proteinosis versus healthy subjects using enhanced depth imaging optical coherence tomography. METHODS: Twenty eyes of 20 patients and the same number of age and sex-matched healthy individuals were enrolled. Comprehensive ocular examinations including measurement of best-corrected visual acuity, spherical equivalent values of refractive errors, and axial length were performed. Choroidal thickness at three points (subfoveal, 500 µm nasal and temporal regions) were measured automatically using MATLAB software. RESULTS: The mean age was 15.68 ± 5.98 years in the patient group and 16.48 ± 5.69 years in the control group. Mean choroidal thickness was statistically significantly thicker at each point in patients with lipoid proteinosis compared to the healthy controls: subfoveal, temporal and nasal choroidal thickness measurements were 425.65 ± 51.42, 380.20 ± 69.66, 334.05 ± 49.98 µm in the study group; 346.15 ± 47.76, 330.15 ± 44.35, 298.95 ± 44.21 µm in the control group, respectively (P < 0.05). CONCLUSION: Patients with lipoid proteinosis have thicker choroid compared to control eyes. Hyalin deposition and ensuing potential inflammation in the disease process may explain this finding.

Measurement of epicardial fatty tissue thickness has a diagnostic value in lichen planus patients and is associated with fibrinogen to albumin ratio and neutrophil to lymphocyte ratio.

OBJECTIVE: Lichen planus (LP) is one of the chronic inflammatory diseases. Epicardial fatty tissue (EFT) is the adipose tissue in which pro-inflammatory and pro-atherogenic hormones and cytokines are secreted. We planned to investigate the predictive value of EFT in LP patients by evaluating together with Fibrinogen to albumin ratio (FAR) other inflammation markers. MATERIALS AND METHODS: A total of 53 consecutive LP patients and 57 healthy controls were enrolled in this single-center, prospective, case-control study. Demographic data were recorded; blood tests were obtained from both groups. Then, EFT thickness was measured by echocardiography. RESULTS: Fibrinogen, FAR, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio, and EFT thickness were higher in LP patients (p < 0.05, for all). EFT was positively correlated with FAR (r = 0.306, p = 0.001), NLR (r = 0.240, p = 0.011), and PLR (r = 0.297, p = 0.002). ROC analysis indicated that FAR could predict LP with a sensitivity of 83 % and a specificity of 44 %; NLR could predict LP with a sensitivity of 80 % and a specificity of 46 %; EFT could predict LP with a sensitivity of 79 % and a specificity of 54 %. In the binary logistic regression analysis NLR, FAR, and EFT were found to be independent predictors of LP. CONCLUSION: We found a relationship between LP and FAR together with other inflammation parameters NLR, and PLR. We demonstrated for the first time that FAR, NLR and EFT were independent predictors of LP. Also, there was a significant relationship between these parameters and EFT (Tab. 4, Fig. 1, Ref. 30).

Treatment of pediatric cutaneous leishmaniasis with liposomal amphotericin B.

The use of liposomal amphotericin B (L-AmB) in the treatment of cutaneous leishmaniasis (CL) is increasing. However, few data are available regarding the efficacy and safety of L-AmB in pediatric CL patients. Our aim in this study is to evaluate the efficacy and safety of L-AmB in pediatric CL patients. Pediatric patients admitted to a tertiary training and research hospital in a hyperendemic region for CL between January 2019 and May 2021 and receiving L-AmB therapy for CL were included in this retrospective study. L-AmB treatment was administered as 3 mg/kg for 5 consecutive days and on the 10th day, in a total of 6 doses (18 mg/kg total dose). A total of 52 pediatric patients who received L-AmB therapy for CL were included in the study. In the follow-up 3 months after L-AmB treatment, 16 (31%) patients showed complete clinical recovery, while treatment failure was detected in 36 (69%) patients. In conclusion, considering the low treatment success rate in our study, we think that the L-AmB dose used in our study is not an appropriate treatment option for the treatment of pediatric CL patients. However, we think that prospective studies with a large number of patients treated with higher doses of L-AmB and in whom the causative agents of CL were determined are needed.

Evaluation of inflammatory parameters in patients with cutaneous leishmaniasis.

Cutaneous leishmaniasis (CL) is a vector-borne parasitic disease characterized by various skin lesions that can cause deformities when healed. Our aim in this study is to show the utility of parameters such as neutrophil/lymphocyte ratio (NLR), thrombocyte/lymphocyte ratio (TLR), and mean thrombocyte volume (MTV) as auxiliary laboratory methods in CL patients. About 107 patients who were admitted to our dermatological and venereal diseases outpatient clinic between January 2018 and January 2019 and were diagnosed with CL by microscopic examination and 74 healthy individuals were included in the study. There were no significant differences between the patient and control group in terms of neutrophil counts, leukocyte counts, platelet counts, and NLR values (P values: .271, .053, .263, and .459, respectively). When the TLR and MTV values of patients with CL and those of the healthy controls were compared, it was found that TLR and MTV values were statistically higher in patients with CL (P values of .010 and .044, respectively). Based on these data, NLR was not considered to be a suitable parameter for demonstrating inflammation in CL patients, but TLR and MTV were held to be an appropriate parameter for demonstrating inflammation in CL patients. In addition, we think that the increase in MTV and TLR, can be used as an auxiliary laboratory test in the diagnosis of CL disease.

Retinal nerve fibre layer thickness and choroidal thickness: An evaluation in psoriasis patients.

BACKGROUND/OBJECTIVES: To conduct a comparative study of retinal nerve fibre layer (RNFL) thickness and choroidal thickness of psoriasis patients and healthy volunteers. METHODS: This study included 35 severe psoriasis patients, 35 mild psoriasis patients and 35 healthy individuals. RNFL and choroidal thickness analysis were performed by spectral field optical coherence tomography (SD-OCT). Only patients with psoriasis vulgaris who have not used systemic therapy for the last 3 months were included in the study. RESULTS: In the severe psoriasis group, the RSLT thickness was found to be statistically significantly thinner and the choroid thickness was thicker than the mild psoriasis and control group (P < .001). There was no significant difference in terms of RNLF and choroid thickness compared to mild psoriasis and the control group (P > .05). The correlation between length of the disease duration, RNFL and choroidal thickness was not significant (P > 0,05). CONCLUSION: The increase in choroidal thickness was found to be significant, while with respect to RNFL thickness, a decrease was evident, a possible indicator of damage to microvascular structures in the choroid and ganglion cells, especially in patients with severe psoriasis. Therefore, choroidal and RSLT thickness measurement with OCT device can assist in the detection of damage to psoriasis.

Are the kidneys involved in lipoid proteinosis? Study of 22 patients.

AIM: Lipoid proteinosis (LP) is a systemic, progressive, rare genodermatosis that manifests in early life with mucocutaneous lesions. Kidney involvement has not been described before, hence we aimed to investigate kidney findings in LP patients. MATERIALS AND METHODS: In this cross-sectional study, LP patients who were followed up and diagnosed with clinical, histopathological and radiological findings in the Dermatology outpatient clinic were invited to the Pediatric Nephrology Clinic. Biochemical, spot urine and 24-hour urine collection tests and ultrasound scans were scanned for the functional and anatomical status of the kidneys. Healthy controls who visited the Pediatric Nephrology Clinic during study periods for other reasons were invited to participate as the control group. RESULTS: Data of 44 participants (22 LP patients, mean age 14.5 years and 22 healthy controls, mean age 14.3 years) were available for the analysis. Ultrasound scans revealed simple renal cysts in 68% of LP patients. The cysts were bilateral in 4 patients, while no cyst was detected in healthy controls. Biochemical parameters, proteinuria, and albuminuria were all within the normal reference range in both LP patients and healthy controls, whereas LP patients had statistically significant lower serum albumin and higher C-reactive protein levels than healthy controls. CONCLUSION: Multiple simple renal cysts were detected in the majority of LP patients, and this finding could be part of the systemic involvement of the disease. Renal functions and biochemical parameters were within the normal reference range, but low serum albumin and high C-reactive protein levels in LP patients may be the signs of elevated systemic inflammation. Although more studies are needed to better define these findings, the presence of many simple renal cysts in LP patients was found to be the most important finding of this study.

The effect of secukinumab treatment on inflammatory parameters in patients with psoriasis: A multicentre restrospective study.

AIM: Psoriasis is a common chronic inflammatory disease of the skin with remission and relapses. The aim of this study was to investigate the change in inflammatory parameters such as neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and mean platelet volume (MPV) in patients receiving secukinumab treatment for psoriasis vulgaris (PV). MATERIALS AND METHODS: In this retrospective study, we evaluated the laboratory results of 40 patients who were followed up with a diagnosis of PV and received secukinumab treatment in three different dermatology clinics between July 2018 and September 2019. RESULTS: Neutrophil count and leukocyte count were significantly decreased after secukinumab treatment. (P < .001) There was no statistically significant difference between lymphocyte count, platelet count, MPV, NLR and PLR values before treatment and at the 4th month of treatment (P values .230, .065, .110, .915 and .365, respectively). CONCLUSION: In conclusion, it can be concluded that parameters such as NLR, PLR and MPV are not suitable parameters for monitoring the effects of secukinumab treatment on inflammation.

Evaluation of thiol/disulphide balance in patients with cutaneous leishmaniasis.

OBJECTIVE: The aim of this study was to evaluate serum thiol disulphide levels in patients with cutaneous leishmaniasis (CL) compared with a healthy control group and to investigate whether thiol/disulphide balance can be used as a new marker of oxidative stress in CL patients. MATERIAL AND METHODS: This prospective study included 47 patients diagnosed with CL and 46 healthy individuals without any disease. Native thiol, disulphide and total thiol levels were used in plasma. Disulphide/total thiol, disulphide/native thiol and native thiol/total thiol levels were measured. RESULTS: Disulphide, native thiol disulphide and total thiol disulphide levels were significantly lower in CL patients compared with the control group. However, there was no statistically significant difference between CL patients and the control group in terms of disulphide/native thiol, disulphide/total thiol and native thiol/total thiol values. CONCLUSION: Based on the data in our study, it can be said that the use of thiol/disulphide balance as a new oxidative stress marker in CL patients is not appropriate, but studies with a larger number of patients are needed.

Atypical and unusual morphological variants of cutaneous leishmaniasis.

OBJECTIVE: Cutaneous leishmaniasis (CL) is a skin disease characterised by prolonged nodulo-ulcerative lesions of the skin that heals with atrophic scar. Clinical features of CL vary depending on the type of parasite and host immune resistance. The aim of this study was to investigate the clinical features of atypical and unusual morphological variants of CL patients diagnosed in our clinic. MATERIALS AND METHODS: In this prospective study, 27 CL patients with atypical clinical features among 486 patients admitted to our clinic between July 2018 and September 2019 and diagnosed as CL by slit-skin smear examination or histopathological examination were included. RESULTS: Of 27 patients, 15 (55.5%) were male and 12 (44.5%) were female. The mean age of the patients was 25.8 ± 7.62 years. Seven (25.9%) patients had lupoid lesions, five (18.6%) patients had eczematoid lesions, four (14.8%) patients had lip lesions, three (11.1%) patients had erysipelas-like lesions, two (7.4%) patients had eyelid lesions, two (7.4%) patients had sporotrichoid lesions, two (7.4%) patients had verrucous lesions, one (3.7%) patient had psoriasiform lesion and one (3.7%) patient had paronychial lesion. CONCLUSION: In conclusion, rare clinical forms of CL are presented in this study. It should be kept in mind that CL may have very different clinical features and should be considered in the differential diagnosis of eczema, psoriasis, erysipelas, sporotrichosis, paronychia and verrucous lesions.

Evaluation of inflammatory parameters in lipoid proteinosis patients.

Lipoid proteinosis (LP) is a rare metabolic storage disease characterized by the storage of hyaline-like substances in the skin, mucosa, and many other organs. The aim of this study was to compare the neutrophil/lymphocyte ratio (NLR), platelets/lymphocyte ratio (PLR), and mean platelet volume (MPV) values of LP patients with healthy control group and to determine the usefulness of these parameters in determining the inflammatory status in LP patients. This study included 14 patients who were admitted to our clinic between March 2013 and January 2017 and diagnosed as LP with clinical, radiological, and histopathological examinations with 14 individuals who had no systemic inflammatory disease or malignancy and has a hemogram result. There was no statistically significant difference between the two groups in comparison to the MPV and PLR values of the patients with LP and healthy controls (P values 0.666 and 0.654, respectively). When the NLR values of the patients with LP and healthy controls were compared, it was found that the LP-diagnosed NLR values were statistically higher. (P: 0.019). In conclusion, it can be said that NLR is an appropriate parameter in demonstrating inflammation in LP patients, but PLR and MPV are not a suitable parameter in demonstrating inflammation in LP patients. Prospective studies with more patients are needed.

The effect of biological agent treatment on neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, mean platelet volume, and C-reactive protein in psoriasis patients.

INTRODUCTION: In recent years, the neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), mean platelet volume (MPV) and C reactive protein (CRP) have been shown to be important indicators of systemic inflammation. Studies have shown that NLR, PLR, MPV and CRP are higher in psoriasis patients than in the control group. AIM: To investigate the NLR, PLR, MPV and serum CRP levels in patients who were treated with biological agents for psoriasis. MATERIAL AND METHODS: In our study, 75 patients who were followed up and had a diagnosis of psoriasis vulgaris and took a biological agent therapy between January 2014 and December 2017 in the Dermatology Clinic of the Dicle University Medical Faculty Hospital were evaluated before treatment, and 3 and 6 months after treatment. RESULTS: Neutrophil count, lymphocyte count, thrombocyte count, NLR, PLR, MPV and CRP values before the biological agent treatment were statistically higher than the values at 3 and 6 months of treatment. There was no statistically significant difference between pre-treatment neutrophil, lymphocyte, leukocyte, platelet, NLR, PLR, MPV, CRP values and values at 3 and 6 months after treatment when we compared four different biological agents. CONCLUSIONS: It was seen that NLR, PLR, MPV and CRP values decreased independently of the type of the biological agent used in our study. Therefore, we think that these parameters can be used to evaluate the effects of biological agent treatment on systemic inflammation in psoriasis patients and to monitor the course of the disease.

Phytodermatitis in East and southeast of Turkey: A prospective study.

OBJECTIVE: Some plants may cause cutaneous side effects called phytodermatitis due to skin contact. Plants that cause phytodermatitis vary according to countries and regions. The aim of this study was to examine the phytodermatitis cases seen in Turkey's east and southeast and compare them with phytodermatitis cases seen previously in the literature in these provinces and to revise the literature. MATERIAL AND METHODS: In this study, 34 patients with phytodermatitis were prospectively evaluated. The demographic and clinical characteristics of the patients such as age, sex, affected areas, dermatitis type, and plant name were recorded. RESULTS: Phytophotodermatitis (PPD) developed in 7 (20,5%) of 34 patients. PPDs occured after contact of Heracleum persicum, Ferula orientalis and Chaerophyllum macropodum Boiss. Two (5.8%) patients developed allergic contact dermatitis due to Xanthium strumarium. Irritant contact dermatitis (ICD) developed in 25 patients (73.5%). ICD was most frequently associated with Tragopogon porrifolius (8 patients). In other patients, ICD was developed due to Ranunculus arvensis, Mentha pulegium, Euphorbia helioscopia, Heracleum persicum, Malva sylvestris, Mandragora autumnalis, Plantago major, and Rheum ribes. CONCLUSION: In our study, we determined the cases of PPD caused by F. orientalis and Chaerophyllum macropodum Boiss, which were not previously described in the literature, and ICD which was caused by R. ribes. Clinicians should be aware that cutaneous reactions due to these plants may develop. Our study is the first comprehensive and prospective study on phytodermatitis in Turkey. More studies are needed to determine causes and prevalance of phytodermatitis in Turkey.

The effect of pentavalent antimonial compounds used in the treatment of cutaneous leishmaniasis on hemogram and biochemical parameters.

Objective: The aim of this study was to analyze the effect of pentavalent antimonials used in the treatment of cutaneous leishmaniasis (CL) on hemogram and biochemical parameters. Material and methods: The study consisted of 168 patients diagnosed with CL after microscopic examination and treated with either systemic sodium stibogluconate (SSG) or meglumine antimonate (MA) 20 mg/kg/day for 14 days. The patients were divided into two groups as SSG and MA patients. Neutrophil count, leukocyte count, lymphocyte count, hemoglobin concentration, platelet count, amylase, lipase, alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood urea nitrogen and serum creatinine levels were compared before and on the 14th day of the treatment. Results: There was a statistically significant decrease in the neutrophil, lymphocyte, leukocyte, platelet counts, and hemoglobin and blood urea nitrogen levels on the 14th day of the treatment when compared to the pre-treatment values. A statistically significant increase was found in the ALT, AST, amylase and lipase levels. No significant change was found in the serum creatinine levels. Conclusion: According to the results of our study, pentavalent antimonials given standard doses in the treatment of CL can lead to an increase in the pancreatic enzymes and transaminases and bone marrow suppression. We do not recommend any change in the treatment if these conditions are not corroborated by clinical findings.

Colchicine may be of therapeutic benefit in prurigo pigmentosa.

Prurigo pigmentosa (PP) is a rare inflammatory skin disease. Neutrophil-mediated inflammation is considered to be responsible for the etiopathogenesis of PP. We consider that colchicine may be an effective agent in the treatment of PP since it exerts an antiinflammatory effect by inhibiting neutrophil chemotaxis. Further studies are required to verify whether colchicine is an effective treatment option for PP.
