Investigation of Malaria, Leishmaniasis, and Scabies Risk after Earthquakes and Recommendations for Prevention.

This study examines the risk of malaria, leishmaniasis, and scabies following earthquakes in southeastern Türkiye. The focus is on the impact on the local population and Syrian immigrants. Recommendations for prevention include vector control measures such as indoor residual spraying and distribution of insecticidal nets. Surveillance and early detection through rapid diagnostic tests and active case finding are important. Public awareness campaigns and community engagement are crucial for promoting protective measures. Strengthening healthcare infrastructure, providing essential supplies, and capacity building is essential. For leishmaniasis, early detection and treatment, vector control, health education, and community engagement are vital. Scabies outbreaks affect the socioeconomically depressed local population and Syrian immigrants. Early detection, treatment, contact tracing, health education, hygiene promotion, and improved living conditions are necessary. Implementing these interventions and strategies can effectively prevent, control, and manage these diseases. Tailoring approaches to the specific context and needs of affected communities is crucial. By addressing these challenges, we can protect the health and well-being of the affected population.

Investigation of in vitro Efficacy of Miltefosine on Chronic Cutaneous Leishmaniasis

Objective: Leishmaniasis is the second deadliest parasitic disease in the World Health Organisation's list of neglected diseases, following malaria. Cutaneous leishmaniasis (CL) is the most common form of the disease and it is one of the few communicable diseases with increasing incidence rates owing to factors like armed conflicts and climate change. CL can be divided into two major groups: Acute CL (ACL) and chronic CL (CCL). The aim of this study was to compare the in vitro efficacy of miltefosine and pentavalent antimony compounds in the CCL patient samples. Methods: Five isolates previously isolated from 5 CCL patients were included in this study. Genotyping is performed using internal transcribed spacer 1 (ITS 1) gene region real-time PCR. In vitro drug efficacy tests were applied to determine their activity against meglumine antimoniate (MA) and miltefosine. Serial dilutions (512, 256, 128, 64, 32, 16, 8 and 4 µg/mL) prepared from MA and miltefosine were prepared in 96-well flat-bottom cell culture plates and incubated at 24 °C for 48 hours. The efficacy of the drug on Leishmania spp. promastigotes after 24 and 48 hours was evaluated by hemocytometer slide and XTT cell viability test. Results: All of the samples were genotyped as L. tropica. Evaluation of 24 and 48 hours showed, 128 µg/mL and 256 µg/mL and 32 µg/mL and 64 µg/mL concentrations of miltefosine and MA were enough to kill all the promastigotes respectively. The results of the hemocytometer slide and XTT were consistent. Conclusion: There are no studies investigating the in vitro efficacy of miltefosine with the CCL patient group. To overcome the treatment challenges experienced in this special patient group, more studies are needed. According to our results, it is concluded that miltefosine is efficient for the treatment of CCL and further clinical studies with miltefosine will reveal valuable data.

Evaluating the Glucantime Concentration for the ex vivo Glial Cell Model of Antimony-resistant Leishmania tropica Amastigotes

Objective: Because the protocols used in the treatment of leishmaniasis can be toxic and have many limitations, such as the development of resistance against such protocols, new treatment options are needed, especially against resistant patients. Ex vivo models may be a good source for evaluating new drug options for patients with antimony-resistant parasites. This study aimed to evaluate the Glucantime concentration for our ex vivo glial cell amastigote model we had defined in previous work. Methods: We prepared the astroglial cell culture from brains of 2 to 3 day old neonatal Sprague-Dawley rats under sterile conditions by modifying McCarthy's method. Four plates of cells were infected with antimony-resistant Leishmania tropica promastigotes. After 24 h of incubation, we added Glucantime to 3 plates with different concentrations. After 72 h, we removed the supernatant and then dried, fixed, and stained the plates with Giemsa to count the amastigotes in the glial cells. Results: We observed the amastigotes in glial cells in the control flask. Glial cells were ruined in flasks, which include 75 µg/mL and 37.5 µg/mL Glucantime. The number of amastigotes per 100 glial cells was 116 for the flask with 7.5 µg/mL Glucantime concentration, while 487 for the control flask. Conclusion: We found that while high concentrations of Glucantime were toxic for glial cells, 7.5 µg/mL Glucantime concentration managed to reduce the number of Leishmania tropica amastigotes in glial cells.

A multicentre prospective analysis of the incidence of pemphigoid diseases in Turkey.

BACKGROUND: The differentiation between the pemphigoid diseases is essential for treatment and prognosis. In Turkey, data on the incidence of these diseases are insufficient. Our aim in this study is to determine the incidence, demographics and clinical characteristics associated with diseases of the pemphigoid group. METHODS: We prospectively analysed 295 patients with pemphigoid who visited dermatology clinics of tertiary referral hospitals in 12 different regions of Turkey within a year. The diagnosis was based on clinical, histopathological, direct immunofluorescence (DIF) and serological (multivariant enzyme-linked immunosorbent assay [ELISA], indirect immunofluorescence and mosaic-based BIOCHIP) examinations. Clinical and demographic findings, aetiological factors and concomitant diseases observed in the patients were recorded. RESULTS: A total of 295 (female/male ratio: 1.7/1) patients with pemphigoid were diagnosed in 1-year period. The overall incidence rate of pemphigoid diseases was found to be 3.55 cases per million-years. The ratio of pemphigoid group diseases to pemphigus group diseases was 1.6. The most common pemphigoid type was bullous pemphigoid (BP, 93.2%). The others were epidermolysis bullosa acquisita (3.1%), pemphigoid gestationis (2.4%), linear IgA disease (1%) and mucous membrane pemphigoid (0.3%). The most common (26.8%) possible trigger of the bullous pemphigoid was gliptin derivative drugs. The most common concomitant diseases with pemphigoid were cardiovascular (27.8%) and neurological diseases (23.7%). CONCLUSIONS: This study showed that the increased frequency of bullous pemphigoid reversed the pemphigoid/pemphigus ratio in Turkey. Further studies are warranted regarding the reasons for this increase.

Overcoming the Challenge; In Vivo Efficacy of Miltefosine for Chronic Cutaneous Leishmaniasis.

BACKGROUND: Cutaneous Leishmaniasis (CL) is the most common form of leishmaniasis. CL can be divided into two major groups: acute CL (ACL) and chronic CL (CCL). The aim of this study is to compare the efficacy of miltefosin and pentavalent antimony compounds in vivo with the CCL patient samples. MATERIALS: Three study groups were formed, each consisting of five male Mus musculus (Balb/C) mice. In this model, promastigotes from the culture of a CCL patient were utilized. 100 µL L. tropica promastigote suspension with a density of 108 promastigotes/ml were injected into the hint-right footpad of each experimental animal intradermally. Footpads of the mice were measured every two weeks until 24th week. From the 13th week, miltefosin 50 mg/kg/day was administered orally using gavage for 21 days, Meglumin antimoniate (MA) was administered by intramuscular (IM) injection daily for 21 days at 50 mg/kg/day and saline was administered IM for 21 days for the miltefosine, MA and control group, respectively. RESULTS: The footpad measurements of the miltefosine group were lower than the control group statistically. Between the MA group and the miltefosine group and MA group and the control group, there was no statistically significant difference. Giemsa stained slides revealed amastigotes in one, two and all of the slides for the miltefosine, MA and control group, respectively. Molecular tests were performed with the Rotor-Gene device and L. tropica consistent peaks were obtained in one of the miltefosine group, four in the MA group and all mice in the control group. CONCLUSIONS: Demonstration of both clinical and laboratory improvement in four of the five experimental animals provides strong evidence that miltefosine is an effective drug in the treatment of CCL. In the literature, no clinical or laboratory studies using miltefosine have been performed with CCL patients only.

[Determination of Antimony Resistance Mechanism of Leishmania tropica Causing Cutaneous Leishmaniasis in Turkey]. / Türkiye'de Kutanöz Leysmanyazis Etkeni Leishmania tropica'da Antimon Direnç Mekanizmasinin Belirlenmesi.

World Health Organization reported that approximately one billion people are at risk in endemic areas, one million cases of cutaneous leishmaniasis (CL) and approximately 300,000 cases of visceral leishmaniasis (VL) were reported per year in the last five years. The number of deaths due to VL is reported to be approximately 20,000 per year. Approximately 2500 cases/year have been reported as CL, caused by Leishmania tropica and Leishmania infantum, in Turkey. The significant increase observed in many cities mainly in the provinces of Mediterranean and Aegean regions in cases and foci in recent years, suggests that there may be an increase in this infections in the following years as well. In Turkey, the causative agent of CL is L.tropica and meglumine antimoniate is used in the treatment of CL. We aimed to determine antimony resistance genes specific for L.tropica by comparing the gene and protein expressions of antimony-resistant and non-resistant L.tropica strains. L.tropica isolates obtained from 3 CL patients without antimonate resistance from Aegean, Mediterranean and Southeastern regions of Turkey were provided to transform into 3 resistant isolates against meglumine antimony in the laboratory conditions. Gene expression alterations by microarray method; protein profiles by two-dimensional gel electrophoresis (2D-PAGE) and relevant proteins by MALDI-TOF/TOF MS of these isolates were accomplished and compared. L.tropica isolates from 10 CL patients who did not respond to antimony therapy were analyzed for resistance to antimonial compounds and quantitative real-time polymerase chain reaction was performed to detect the expression of genes responsible for resistance development. Moreover, differences in protein expression levels in isolates with and without antimony resistance were determined by comparing protein profiles and identification of proteins with different expression levels was carried out. Enolase, elongation factor-2, heat shock protein 70, tripanthione reductase, protein kinase C and metallo-peptidase proteins have been shown to play roles in L.tropica isolates developing resistance to antimonial compounds and similar expression changes have also been demonstrated in naturally resistant isolates from patients. In conclusion, it was revealed that L.tropica strains in our country may gain resistance to meglumine antimoniate in a short time. It is foreseen that if the patients living in our country or entering the country are treated inadequately and incompletely, there may be new, resistant leishmaniasis foci that may increase the number of resistant strains and cases rapidly.

Comparison of in vitro Resistance of Wild Leishmania Isolates, Which are Resistant to Pentavalent Antimonial Compounds, Against Drugs Used in the Treatment of Leishmaniasis

Objective: Meglumine antimoniate (Glucantime®) and Sodium stibogluconate (Pentostam®) are used for the treatment of cutaneous leismaniasis in Turkey. There is a reported resistance to these drugs in recent years. The aim of the present study was to compare the in vitro sensitivities of resistant Leishmania isolates against Amphotericin B, Miltefosine, Meglumine Antimoniate, Paromomycin and Sodium Stibogluconate. Methods: Five Leishmania isolates of patients with cutaneous leishmaniasis, who showed no clinical recovery despite two consecutive meglumine antimoniate treatments, which were stored in the Parasite Bank in Manisa Celal Bayar University Medical Faculty were selected. They were genotyped with Real-Time PCR using specific primers and probes to ITS1 region. Drug resistance levels of each Leishmania isolate were analysed for Amphotericin B, Miltefosine, Meglumine Antimoniate, Paromomycin, and Sodium Stibogluconate at concentrations of 500, 250, 125, 50, 25 µg/mL with XTT method and hemocytometer. Results: It was observed that the resistant Leishmania tropica isolates showed no resistance to Amphotericin B, and were sensitive to Miltefosine, Sodium Stibogluconate, Paromomycin and Meglumin Antimonate, respectively. In addition, Leishmania tropica (MHOM/AZ/1974/SAF-K27) isolate of the control group could stay viable in none of the drug concentrations of five agents in the study. Conclusion: It was determined that none of the selected resistant L. tropica isolates showed resistance to Amphotericin B and that was also shown statistically (p<0.05). The results of this study are important in guiding clinicians and researchers who conduct studies on drugs and search for new drug molecules.

Refugees at the Crossroads of Continents: A Molecular Approach for Cutaneous Leishmaniasis Among Refugees in Turkey.

PURPOSE: Due to mass population movements driven by internal conflicts and wars, cutaneous leishmaniasis (CL) is becoming increasingly important in Turkey. This study is aimed at determining the clinical aspects, diagnosis and genotyping of CL patients coming to Turkey from abroad. METHODS: In our study, the clinical materials obtained from the patients or sent for diagnostic purposes from other centers to our laboratory between years 2012 and 2016 were assessed retrospectively. In total, there were 38 patients from Syria, Iraq, Afghanistan, Iran, and Turkmenistan. RESULTS: 29 (76%), 28 (73%) and 33 (87%) samples were positive by light microscopy, Novy-McNeal-Nicolle(NNN), and enriched medium, respectively. By ITS-1 gene region PCR, 31 (81%) of the cases were positive. 35 of the patients were tested positive by at least one of the diagnostic methods. By genotyping, 21 Leishmania tropica, 8 Leishmania major, 3 Leismania infantum, 2 Leishmania donovani, and 1 Leishmania aethopica were detected. CONCLUSION: This study is aimed at informing the clinicians working in the field for the import CL cases and recording the changing epidemiological features of CL in the region as well as discussing the possible focus for L. aethiopica infection which has not been shown in the region before.

Rituximab therapy in pediatric pemphigus patients: A retrospective analysis of five Turkish patients and review of the literature.

BACKGROUND/OBJECTIVES: There is inadequate knowledge regarding rituximab (RTX) administration in autoimmune bullous diseases (AIBDs), disease prevalence, clinical characteristics, and treatment outcomes within pediatric populations due to the rarity of AIBDs affecting the pediatric age group. The aim of this retrospective analysis was to evaluate the effectiveness, safety of RTX, and treatment outcomes in Turkish pediatric patients with pemphigus vulgaris (PV) and to review the literature. METHODS: Five patients under 18 years of age and diagnosed with PV received RTX treatment and were identified in four dermatology departments of Turkey. RESULTS: The mean age of the patients at the time of RTX therapy initiation was 15 years (range: 11-17 years), and the total duration of follow-up after RTX therapy was 42.6 months (range: 19-60 months). All patients showed a clinical response. At the last visit, complete remission off therapy was achieved in three patients. The remaining two patients achieved partial remission off therapy. No adverse events were observed. CONCLUSIONS: This retrospective case series of five pediatric patients showed that RTX treatment can be effective and safe for the treatment of recalcitrant PV in pediatric patients. With increasing evidence, RTX is a good treatment choice in adults and pediatric patients with pemphigus.

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.

The current clinical and geographical situation of cutaneous leishmaniasis based on species identification in Turkey.

Leishmaniases are a group of vector-borne diseases caused by the members of Leishmania genus, and there are three main clinical forms of the infection as visceral, cutaneous, and mucocutaneous. Cutaneous leishmaniasis is a growing public health problem in Turkey due to increasing detection of autochthonous cases caused by L. major and L. donovani in some regions in addition to Syrian imported cases. For this reason, we aimed to evaluate the current epidemiological situation of CL in the view of causative agents and their geographical distribution throughout Turkey. The samples were collected from 356 CL patients admitted to different centers in 18 provinces between January 2013 and December 2016. Direct microscopy, culture (regular and enriched NNN) and molecular techniques (real-time ITS1 PCR and hsp70 PCR/sequencing) were performed. By molecular techniques, 299, 28, 19 and 10 isolates/clinical samples were identified as L. tropica, L. major, L. infantum and L. donovani, respectively. Most of the patients (65.73%) had one lesion usually on their face/head. Dry-nodular type lesions (n = 291) were mainly associated with L. tropica while L. major was mainly found related to wet-ulcerative ones. Leishmaniasis recidivans was also detected in 2.52% among 356 patients. L. tropica was detected as most widespread species causing CL in Turkey. L. infantum and L. major was also found in one third of the provinces. Enriched NNN culture was worked well for isolating the parasite and 346 isolates were successfully grown and stored in liquid nitrogen. The comparison of all diagnostic techniques showed that the parasitological positivity rate could increase if the combination of direct microscopy and real-time ITS1 PCR is used. Besides well-known anthroponotic L. tropica cases, the increasing detection of CL cases caused by zoonotic species, L. infantum and L. major, is one of the most important findings in the present study. In our opinion to ensure timely and accurate diagnosis, proper treatment and countrywide effective control of CL in Turkey a systematic approach is needed on the base of information about characteristics of lesions and patients and epidemiological features of the disease.

Clinical practice guidelines for the diagnosis and treatment of cutaneous leishmaniasis in Turkey.

BACKGROUND: Cutaneous leishmaniasis (CL) is a vector-born parasitic disease characterized by various skin lesions that cause disfiguration if healed spontaneously. Although CL has been endemic for many years in the southern regions of Turkey, an increasing incidence in nonendemic regions is being observed due to returning travelers and, more recently, due to Syrian refugees. Thus far, a limited number of national guidelines have been proposed, but no common Turkish consensus has emerged. OBJECTIVES: The aim of this study was to develop diagnostic and therapeutic guidelines for the management of CL in Turkey. METHODS: This guideline is a consensus text prepared by 18 experienced CL specialists who have been working for many years in areas where the disease is endemic. The Delphi method was used to determine expert group consensus. Initially, a comprehensive list of items about CL was identified, and consensus was built from feedback provided by expert participants from the preceding rounds. RESULTS: Evidence-based and expert-based recommendations through diagnostic and therapeutic algorithms according to local availability and conditions are outlined. CONCLUSION: Because CL can mimic many other skin diseases, early diagnosis and early treatment are very important to prevent complications and spread of the disease. The fastest and easiest diagnostic method is the leishmanial smear. The most common treatment is the use of local or systemic pentavalent antimony compounds.

[Infecting glial cells with antimony resistant Leishmania tropica: A new ex-vivo model]. / Glia hücrelerinin antimona dirençli Leishmania tropica ile enfekte edilmesi: Yeni bir ex-vivo modeli.

Leishmaniasis is a vector-borne zoonotic disease that shows different clinical features like cutaneous, mucocutaneous, visceral and viscerotropic forms. The protocols used in the treatment of leishmaniasis are toxic and have many limitations during administration. One of the limitations of treatment is the resistance against the protocols in practice. There is also a need to define new treatment options especially for resistant patients. Ex-vivo models using primary cell cultures may be a good source for evaluating new drug options in patients with antimony resistance, in addition to in-vitro and in-vivo studies. In this study, it was aimed to define a new ex-vivo culture model to evaluate treatment options in patients with cutaneous leishmaniasis who did not respond to treatment. In our experimental model of ex-vivo infection, Leishmania tropica promastigotes isolated from a case previously diagnosed with cutaneous leishmaniasis were used. The primary astroglial cell culture used for the ex-vivo model was prepared from 2-3 days old neonatal Sprague Dawley rat brains under sterile conditions by the modification McCarthy's method. The astroglia cells, which reached sufficient density, were infected with antimony resistant L.tropica promastigotes. After 24 hours of incubation, the supernatant on the cells were collected, the cell culture plate was dried at room temperature, then fixed with methyl alcohol and stained with Giemsa to search for L.tropica amastigotes. Amastigotes were intensely observed in glia cells in primary cell cultures infected with L.tropica promastigotes. No promastigotes were seen on Giemsa stained preparations of the precipitates prepared from the bottom sediment after the centrifugation of the liquid medium removed from the infected plates. In this study, promastigotes from a cutaneous leishmaniasis patient unable to respond to pentavalent antimony therapy were shown to infect rat glia cells and converted to amastigote form. This amastigote glial cell model, as far as we know, is the first model in the literature produced by L.tropica. The occurrence of L.tropica amastigote forms in glia cells may be indicative of the ability of Leishmania species to infect the central nervous system. The central nervous system may be an area for the Leishmania amastigotes to escape from the immune system in cases of leishmaniasis without a treatment response. Our study is important because it is the first study to show the infection of glia cells with L.tropica amastigotes.

Asymptomatic flesh-colored lobular nodule on the nose.

Chondroid syringoma is a rare benign tumor of the skin appendages. Chondroid syringoma is mostly manifested by a slow-growing, painless, well defined subcutaneous or intradermal nodule. A 43-year-old man presented to our clinic with the complaint of an asymptomatic nodule on the dorsum of the nose for 8 months. The lesion was totally excised. Histopathological examination was notable for epithelial islets embedded in the chondroid matrix in the dermis. The patient was diagnosed with chondroid syringoma in light of the clinical and histopathological findings.

Epidemiology of Pemphigus in Turkey: One-year Prospective Study of 220 Cases.

Pemphigus is a group of rare and life-threatening autoimmune blistering diseases of the skin and mucous membranes. Although they occur worldwide, their incidence shows wide geographical variation, and prospective data on the epidemiology of pemphigus are very limited. Objective of this work is to evaluate the incidence and epidemiological and clinical features of patients with pemphigus in Turkey. All patients newly diagnosed with pemphigus between June 2013 and June 2014 were prospectively enrolled in 33 dermatology departments in 20 different provinces from all seven regions of Turkey. Disease parameters including demography and clinical findings were recorded. A total of 220 patients were diagnosed with pemphigus during the 1-year period, with an annual incidence of 4.7 per million people in Turkey. Patients were predominantly women, with a male to female ratio of 1:1.41. The mean age at onset was 48.9 years. Pemphigus vulgaris (PV) was the commonest clinical subtype (n=192; 87.3%), followed by pemphigus foliaceus (n=21; 9.6%). The most common clinical subtype of PV was the mucocutaneous type (n=83; 43.2%). The mean Pemphigus Disease Area Index was 28.14±22.21 (mean ± Standard Deviation). The incidence rate of pemphigus in Turkey is similar to the countries of South-East Europe, higher than those reported for the Central and Northern European countries and lower than the countries around the Mediterranean Sea and Iran. Pemphigus is more frequent in middle-aged people and is more common in women. The most frequent subtype was PV, with a 9-fold higher incidence than pemphigus foliaceus.

Bullous Hemorrhagic Dermatosis Induced by Enoxaparin.

Bullous hemorrhagic dermatosis induced by enoxaparin is a rare, self-limiting, cutaneous adverse reaction causing no complications. In this report, we present a case where bullous hemorrhagic dermatosis developed at a location distant from the site of injection after using enoxaparin for 5 days for pulmonary venous thrombosis.

Leishmaniasis in Turkey: Visceral and cutaneous leishmaniasis caused by Leishmania donovani in Turkey.

In Turkey, the main causative agents are Leishmania tropica (L. tropica) and Leishmania infantum (L. infantum) for cutaneous leishmaniasis (CL) and L. infantum for visceral leishmaniasis (VL). In this study, we investigated leishmaniasis cases caused by L. donovani and established animal models for understanding its tropism in in vivo conditions. Clinical samples (lesion aspirations and bone marrow) obtained from CL/VL patients were investigated using parasitological (smear/NNN) and DNA-based techniques. For species identification, a real time ITS1-PCR was performed using isolates and results were confirmed by hsp70 PCR-N/sequencing and cpb gene PCR/sequencing in order to reveal Leishmania donovani and Leishmania infantum discrimination. Clinical materials from CL and VL patients were also inoculated into two experimental groups (Group CL and Group VL) of Balb/C mice intraperitoneally for creating clinical picture of Turkish L. donovani strains. After 45days, the samples from visible sores of the skin were taken, and spleens and livers were removed. Measurements of the internal organs were done and touch preparations were prepared for checking the presence of amastigotes. The strains were isolated from all patients and amastigotes were seen in all smears of the patients, and then isolates were immediately stored in liquid nitrogen. In real time ITS1-PCR, the melting temperatures of all samples were out of range of L. infantum, L. tropica and L. major. Sequencing of hsp70 PCR-N showed that all isolates highly identical to previously submitted L. donovani sequences in GenBank, and cpb gene sequencing showed five isolates had longer cpbF allele, whereas one isolate contained a mixed sequence of both cpbF and cpbE. All mice in both experimental groups became infected. Compared to controls, the length and width of both liver and spleen were significantly elevated (p<0.001) in both groups of mice. However, the weight of the liver increased significantly in all mice whereas the weight of spleen increased only in VL group. Amastigotes were also seen in all touch preparations prepared from skin sores, spleen and liver. L. donovani strain was isolated from autocutaneous a VL patient first time in Turkey. Animal models using clinical samples were successfully established and important clinical differences of the isolated strains were observed.

Leishmaniasis in Turkey: first clinical isolation of Leishmania major from 18 autochthonous cases of cutaneous leishmaniasis in four geographical regions.

OBJECTIVE: To report isolation of Leishmania major strains obtained from 18 Turkish autochthonous cutaneous leishmaniasis (CL) patients infected with L. major between 2011 and 2014. METHODS: Initial diagnosis relied on microscopy and culture in enriched medium, prepared by adding specific amounts of liver extract, protein and lipid sources to NNN medium. Promastigotes were then transferred to RPMI medium including 10% of foetal calf serum for mass culture. Species-specific real-time PCR targeting ITS1 region of Leishmania spp. was performed using both lesion aspiration samples and cultured promastigotes. Two of 18 isolates were identified by isoenzyme analysis in the Leishmaniasis Reference Center in Montpellier, France. Each isolate was inoculated into the footpads of six mice to observe the pathogenicity of L. major. Developing lesions were observed, and the thickening of footpads was measured weekly. RESULTS: Melting curve analyses of 18 isolates showed a peak concordant with L. major, and two of them were confirmed by isoenzyme analyses as L. major zymodeme MON103. In the mouse model, acute lesions seen on day 21 were accepted as an indication of heavy infection. Severe impairments were observed on all mouse footpads over 3 weeks, which even progressed to extremity amputation. CONCLUSION: Cutaneous leishmaniasis-causing L. major was recently identified in Adana province in southern Turkey, with PCR. Our study shows that such CL cases are not limited to Adana but currently present from western to Southeastern Anatolia, and along the Mediterranean coast. The role of small mammals, the main reservoirs of L. major in Anatolia, needs to be elucidated, as do the underlying factors that cause severe clinical manifestations in L. major infections in Turkey, contrary to the infections in neighbouring countries.

Diagnostic value of telecytology in tertiary teledermatological consultation: a retrospective analysis of 75 cases.

BACKGROUND: The addition of dermatoscopic images to clinical images is reported to increase the diagnostic value of teledermatology. No study has investigated the contribution of telecytology to teledermatology. We aimed to assess the diagnostic accuracy of telecytology in tertiary teledermatological evaluation. METHODS: The study included 75 patients for whom no diagnosis could be established at face-to-face clinical examinations and cytological evaluations, who therefore consulted with a dermatologist experienced in cytology through the store-and-forward method. Telecytological diagnosis was then compared with the final diagnosis, and diagnostic accuracy was calculated. RESULTS: In the past 2 years, 75 patients (38 [50.7%] female, 37 [49.3%] male) were evaluated by telecytology. According to definitive diagnoses, 31 patients (41.3%) had erosive-vesiculobullous, 25 (33.3%) had tumoral, and 19 (15.8%) had granulomatous disease. Diagnostic accuracy of telecytology was 90.7%. LIMITATIONS: Our study was a retrospective study, and cytological images were evaluated by one dermatologist only; therefore, no reliability analysis could be performed. CONCLUSION: This study revealed that the cytological images should be used in tertiary teledermatological evaluation. Further studies should therefore be carried out to investigate the diagnostic value of different telecytological methods.
