Microblading reaction as a manifestation of systemic sarcoidosis: two case reports and a review of the literature.

BACKGROUND: Sarcoidosis is a multisystemic disease characterized by granulomatous inflammation. Sarcoidosis often poses a diagnostic challenge owing to its nonspecific or mild clinical features. In 20-35% of cases, sarcoidosis initially presents on skin. However, skin lesions commonly mimic dermatological conditions. Therefore, it is important to not underestimate the skin manifestations and perform histopathological examinations to make a timely diagnosis. CASE PRESENTATION: We present two cases of 33-year-old Caucasian female patients with orange-red macules and plaques that developed in the eyebrow area 1 and 6 years after microblading, respectively. Histopathological examination confirmed a diagnosis of sarcoidosis. The lymph nodes and lungs were also affected in both patients. CONCLUSION: Our two reports suggest that an esthetic procedure involving dermal or subcutaneous injection of foreign materials can trigger the development of cutaneous and systemic sarcoidosis. However, this relationship has not been described yet. Physicians should, therefore, be aware of this complication to properly evaluate and treat such patients in a timely manner.

Trigeminal trophic syndrome, a rare and often overlooked cause of facial ulceration: a case report and literature review.

Trigeminal trophic syndrome (TTS) is an uncommon and relatively unknown cause of facial ulceration that occurs after damage to the trigeminal nerve. It characteristically involves non-healing facial ulceration(s) with accompanying anesthesia, paresthesia, and dysesthesia along the distribution of a trigeminal dermatome. The ulcerations are believed to be self-induced in response to paresthesia. The disease is most common in middle-aged women, manifesting as a unilateral crescent-shaped ulceration on the ala nasi, with sparing of the nasal tip. The diagnosis is clinical and mostly based on exclusion of other possible causes of facial ulcerations, with emphasis on neoplasms, infection-associated vasculitis, and factitial disorders. There are no specific histological or laboratory signs. There is no standard treatment protocol; however, a number of different successful strategies have been reported, including pharmaceutical and surgical interventions, transcutaneous nerve stimulation, and simple occlusion dressings. Due to the self-inflicted nature of this disorder, the cornerstone of management is patient education with behavioral modification. Here, we report a case of TTS following herpes zoster ophthalmicus and review the current literature on this subject.

Effects of Adequate Iodine Supply on the Incidence of Iodine-Induced Thyroid Disorders in Slovenia.

BACKGROUND: This study aimed to establish the changes in the incidence and characteristics of iodine-induced hyperthyroidism (II-Hyper) and iodine-induced hypothyroidism (II-Hypo) in the two-year period before and the 10-year period after the increase in mandatory salt iodization from the previous 10 mg/kg of potassium iodide to 25 mg/kg in 1999. Furthermore, the aim was to determine the duration of treatment in II-Hyper patients, since no data regarding severity and treatment of II-Hyper with respect to iodine supply are available. METHODS: This retrospective study reviewed medical records of 885 Slovenian patients first diagnosed with II-Hyper or II-Hypo between 1998 and 2009 at the Thyroid Department of the University Medical Centre Ljubljana. II-Hyper and II-Hypo were diagnosed by one out of 10 senior internal medicine specialists. The diagnosis was based on an adequate patient history, and laboratory measurements of thyrotropin, thyroid hormones, and thyroid antibodies. In most cases, thyroid ultrasound and thyroid scintigraphy were performed. Demographic characteristics and the type and the duration of treatment were also reviewed. RESULTS: The incidence of II-Hypo was significantly higher after the increase in iodine supply than it was before (p < 0.001). After the increase in iodine supply, the incidence of II-Hyper was significantly lower than before the increase (p < 0.001). Furthermore, the portion of patients with overt hyperthyroidism decreased, predominantly due to the increased proportion of patients with subclinical hyperthyroidism (p = 0.007 and p = 0.015, respectively). The duration of treatment with antithyroid drugs and perchlorate was significantly shorter after the increase in iodine supply than it was before (p = 0.001 and p = 0.002, respectively). A significantly positive correlation between the year of the occurrence of excessive iodine intake (EII)-induced thyroid disease and the duration of treatment with amiodarone was found (R = 0.132; p = 0.048), suggesting that the longer the patients had an adequate iodine supply, the longer they could take amiodarone before EII-induced thyroid disorder developed. CONCLUSIONS: After the increase in iodine supply, a higher incidence of II-Hypo and a lower incidence of II-Hyper were observed than before the increase. Less severe II-Hyper, shorter duration of treatment of II-Hyper, as well as a longer thyroid disease-free period in patients on amiodarone are additional beneficial clinical consequences after the establishment of an adequate iodine supply.

Beneficial effects of adequate iodine supply on characteristics of thyroid autonomy.

OBJECTIVE: Our aim was to establish the characteristics of thyroid autonomy (TA) in Slovenian patients and the required therapeutic dose of radioiodine before and ten years after the increase in mandatory salt iodization from previous 10 mg of potassium iodide to 25 mg per kg in 1999 because almost no data about TA and radioiodine treatment with respect to iodine supply are available. DESIGN: Retrospective clinical study. PATIENTS: We reviewed records of all patients referred for the first time in 1998 and 2009 to the Thyroid Department at the University Medical Centre Ljubljana which is a tertiary referral centre with a stable catchment area for more than 20 years. METHODS: TA was diagnosed by thyroid function, ultrasound, scintigraphy and negative TSH receptor antibodies. Demographic characteristics and the applied dose of radioiodine were evaluated. RESULTS: In 1998, significantly more patients presented with TA than in 2009 (383 of 3243, 11·8% and 333 of 4546, 7·3%, respectively, P < 0·001). In 1998, the ratio between hyperthyroid and euthyroid patients was higher than in 2009 (6:1 and 2·1:1, respectively, P < 0·001). In 1998, patients were younger than in 2009 (mean 63·8 ± 13·9 and 66·8 ± 14·9 years, respectively, P < 0·004). Hyperthyroid patients were older than euthyroid in both years (P < 0·001). In 1998, mean applied dose of radioiodine was significantly lower than in 2009 (713 ± 306 and 791 ± 194 MBq, respectively, P = 0·003). CONCLUSIONS: In adequate iodine supply, TA is less frequent, patients are less often hyperthyroid, they are older and cured with higher doses of radioiodine than in mild iodine deficiency.
