Atypical clinical form of cutaneous leishmaniasis: erysipeloid form

Yelda Karincaoglu; Muammer Esrefoglu; Hamdi Özcan

A 60‐year‐old woman was admitted to our clinic with a gradually enlarging red papule on her face. Her history revealed that, 9 months previously, a painless, red papule of 1–2 cm in diameter had occurred in the middle of her face and, with time, had enlarged to cover her nose, both cheeks, and eyelids. It was diagnosed as a superficial skin infection, and topical and systemic antibiotics were prescribed; however, no response was obtained. In the last 2 months, a sore had formed in the middle of her nose. The patient lives in the east of Eastern Anatolia, where no case of cutaneous leishmaniasis has been reported in the last 20 years.

To determine whether differences exist between neurofibromatosis type 1 (NF1) patients with or without focal lesions and healthy normal volunteers in the metabolite ratios of normal appearing white matter, 27 patients with NF1 (with parenchymal lesion, MR positive, n: 17; without parenchymal lesions, MR negative, n: 10) and 20 healthy volunteers underwent MRI and short TE (31 ms) proton MR spectroscopy (MRS). In 17 patients with parenchymal lesions, 61 focal lesions were detected by MRI. MRS was performed from normal appearing frontal and posterior parietal white matter (FWM and PWM) in NF1 and from control groups. NAA/Cr, Cho/Cr and MI/Cr ratios were calculated. Significant increase in Cho/Cr and MI/Cr ratios were found in FWM and PWM in MR negative and positive groups when compared to control group. NAA/Cr ratio in MR positive group was significantly decreased in FWM compared to control group. There were no significant differences between FWM and PWM in all metabolite ratios of MR negative group. MI/Cr ratio in MR positive group was significantly elevated in PWM compared to FWM. Metabolite changes detected by MRS could indicate demyelination and gliosis in normal appearing white matter in all NF1 patients, and additionally neuroaxonal damage in the FWM of NF1 patients with focal lesions. For that reason, in the clinical evaluation and follow-up of these patients MRS features of normal appearing white matter should be considered in addition to focal lesions.

Muammer Seyhan; Tuba Akı; Yelda Karincaoglu; Hamdi Özcan

BACKGROUND: Dermatological patients quite commonly depict psychiatric morbidity. PURPOSES: To study the psychiatric morbidity among skin patients of our clinic. METHODS: In the present study, the patients who were treated in the Dermatology Clinic of Inonu University Medical Faculty were evaluated retrospectively. The age, gender, marital status, habits, dermatological and systemic diseases, previously used drugs, current therapy and psychiatric diagnosis of each patient were recorded. FINDINGS: Of 636 patients involved in the study, 15.3% had psychopathological problems, which were depression (32.0%), adjustment difficulty (15.5%), anxiety (13.4%), psychosomatic disorders (10.3%), obsessive-compulsive disorder and conversion (5.1%), dysthymic disorder (4.1%), attention deficit and hyperactivity disorder (2.1%), panic attack (1.0%), premenstrual syndrome, schizophrenia, somatization disorder, insomnia, alcohol dependency, bipolar affective disorder, mental retardation, agoraphobia, social phobia and dementia. The dermatological diseases defined for the patients with psychopathology diagnosis were chronic urticaria (25.8%); psoriasis (15.5%); alopecia areata, totalis and iniversalis (11.3%); acute urticaria, neurodermatitis and Behcets disease (5.1%); atopic dermatitis and drug eruptions (4.1%); pemphigus (3.1%); angioedema, contact dermatitis and generalized pruritus (2.1%); folliculitis and the others (1.0%). CONCLUSIONS: Psychiatric morbidity has an affect on the course of dermatological diseases. When required, psychiatric consultation should be sought by dermatology clinics and patients should be followed with the cooperation of dermatologists and psychiatrists. LIMITATION: The indoor-based study had not included any control group and any domicillary patient.

Background  Anthrax is a potentially fatal zoonotic disease. The diagnosis of cutaneous anthrax (CA) may be very difficult, particularly in atypical presentations and nonendemic regions.

Ciprofloxacin-Induced Urticaria and Tenosynovitis: A Case Report

Uner Kayabas; Funda Yetkin; Ahmet Firat; Hamdi Özcan; Yasar Bayindir

Background: Tendon disorders are rare events associated with fluoroquinolone congestion. Skin reactions are more frequent than tendon disorders. We reported this case as the combination of ciprofloxacin-induced urticaria and tenosynovitis has been unreported in young women. Case: A 28-year-old woman without underlying disease developed urticarias and tendinopathy 4 days after the initiation of ciprofloxacin treatment for urinary infection. MRI of the left foot revealed increased synovial fluid surrounding the tendon of the flexor hallucis longus muscle representing tenosynovitis. Ciprofloxacin was ceased due to the possibility of ciprofloxacin-induced tendinopathy and urticaria. Complete resolution of her symptoms and findings occurred 3 days after discontinuation of ciprofloxacin without any additional treatment. Conclusion: Early discontinuation of fluoroquinolone therapy when tendinopathy is suspected is the basis of therapy. So, it should be kept in mind that fluoroquinolone-induced tendinopathy may occur in an otherwise healthy young patient with no risk factors and in a site other than the Achilles tendon.
