A comparison of the 2 thermal ablation procedures for the management of benign thyroid nodules.

INTRODUCTION: In recent years, ultrasound (US)-guided thermal ablation techniques have come to the fore as minimally invasive alternatives to surgery. The purpose of this study was to assess the effectiveness and safety of radiofrequency ablation or microwave ablation procedures in patients with benign thyroid nodules. MATERIAL AND METHODS: This retrospective and single-centre study consisted of 55 patients and 62 benign thyroid nodules that were treated either with radiofrequency ablation (RFA) or microwave ablation (MWA) in our hospital between January 2020 and March 2022. All the patients were at high risk for surgery or with symptomatic TNs and who refused surgery. The TNs diagnosed as benign from the fine-needle aspiration biopsy were evaluated in terms of volume reduction, symptom, and cosmetic scores. In addition, these 2 treatment modalities were compared to each other. RESULTS: Out of 55 patients, 44 (80%) were female and were aged between 24 and 97 years with a median age of 50 years. RFA was applied to 54.5% (n = 30) of the participants, and MWA was applied to 46.5% (n = 25). The volume reduction rate (VRR) after RFA and MWA at the first month was 63.4 ± 14.2 and 65.7 ± 13, respectively. No significant difference was detected between the 2 groups in terms of VRR (p = 0.51). In addition, the mean symptom and cosmetic scores decreased significantly in both procedures, and there was a significant difference due to the symptom score change in the RFA group compared to the MWA group. Of all the patients, one patient experienced haematoma in the RFA, and one patient had transient voice change in the MWA group. No life-threatening complications were noted. CONCLUSION: In the treatment of benign symptomatic thyroid nodules, both RFA and MWA are options worthy of consideration in terms of efficacy and safety.

Oncocytic neoplasms; rare adrenocortical tumours - a report of eleven patients.

INTRODUCTION: Oncocytomas of adrenal glands are extremely rare and usually present as incidentally detected masses. We aimed to present a series of patients with adrenal oncocytomas and review the literature. MATERIAL AND METHODS: Electronic database of patients with adrenal tumours, who were admitted to the internal medicine and endocrinology and metabolism outpatient clinics of Uludag University Medical Faculty between January 2005 and November 2016, were assessed retrospectively. Those who underwent surgery and pathological diagnosis of oncocytoma (n = 11) were included to the study. The demographic, clinical, pathological, radiological, and laboratory features were evaluated. RESULTS: Of these 11 patients, 54.5% (n = 6) were female and 45.5% (n = 5) were male. They aged between 31 and 76 years (45.36 ± 13.68). Five (45.5%) of the masses showed endocrinological activity and were more frequent in women. The masses were 25-130 (57.63 ± 34.04) mm in width and 20-100 (47.82 ± 28.95) mm in length. Seven (63.6%) oncocytomas were classified as benign and the remainder as having uncertain malignant potential according to Lin-Weiss-Bisceglia criteria. Mean duration of follow-up were 24.8 (6-60) months and 38.2 (15-82) months, respectively. CONCLUSIONS: Because there are no unique clinical and imaging characteristics differentiating adrenal oncocytomas from other types of adrenal masses, it should be kept in mind in differential diagnosis of adrenal masses, especially large ones and those suspicious for adrenocortical carcinoma.

Is Parenteral Levothyroxine Therapy Safe in Intractable Hypothyroidism?

CASE: A 32-year old woman was admitted to the hospital due to intractable hypothyroidism refractory to high dose of oral l-thyroxine therapy. She underwent total thyroidectomy and radioactive iodine therapy due to papillary thyroid cancer. After excluding poor adherence to therapy and malabsorption, levothyroxine absorption test was performed. No response was detected. Transient neurologic symptoms developed during the test. She developed 3 attacks consisting of neurologic symptoms during high dose administration. The patient was considered a case of isolated l-thyroxine malabsorption. She became euthyroid after intramuscular twice weekly l-thyroxine therapy. DISCUSSION: There are a few case reports regarding isolated l-thyroxine. We report successful long term results of twice weekly administered intramuscular l-thyroxine therapy. We also draw attention to neurologic side effects of high dose l-thyroxine therapy.

Adrenocortical carcinoma: Single center experience.

OBJECTIVE: Adrenocortical carcinoma is an aggressive endocrine malignancy with an annual incidence of 0.5-2 cases per million. The most important factors that determine prognosis are tumor stage at the time of diagnosis and the success of surgery. However, advanced age, large tumor size, hormone secretion, high Ki-67 index (>10%), tumor necrosis and high mitotic activity are other factors associated with poor prognosis. In the present study, we aimed to evaluate the contribution of the patient and treatment- related factors to the prognosis in adrenocortical carcinoma. MATERIAL AND METHODS: We included 15 adrenocortical carcinoma patients who were followed in our center between 2005 and 2015. The effects of age, gender, tumor size, type of operation, postoperative resection status and adjuvant treatment on disease-free survival and overall survival were analyzed. RESULTS: Disease-free survival was 23.32±3.69 months and overall survival was 36.60±10.78 months. Gender, tumor size, tumor stage, type of operation, hormonal activity, presence of necrosis, recurrence and development of metastasis were not found to be associated with disease-free survival and overall survival (p>0.05). Postoperatively applied adjuvant treatments including mitotane, chemotherapy and radiotherapy did not significantly affect disease-free survival in our study, but statistically significant increase in overall survival was observed in patients getting adjuvant treatments (p=0.006). CONCLUSION: Adrenocortical carcinoma has poor prognosis and short overall survival, and in its clinical course, recurrence and development of metastasis can be commonly observed even after complete resection of the tumor. Therefore, the patients should be evaluated carefully while determining the surgical procedure during the preoperative period, and the operation and post-operative follow-up should be performed in experienced centers. However, due to the positive effects of adjuvant treatments on survival, all patients should be evaluated postoperatively for the necessity of adjuvant treatments, especially mitotane.

Sexual dysfunction in female patients with type 2 diabetes mellitus: a cross-sectional single-centre study among Turkish patients.

The aim of the study was to assess the prevalence of female sexual function and related factors in Turkish women with type 2 diabetes mellitus (T2DM). A total of 93 female patients diagnosed with T2DM (age 48.0 ± 7.2 years (Mean ± SD) were included. Data on age, diabetes age, HbA1c level, educational level, diabetes treatment, diabetes-related complications, co-morbid disorders and concomitant medications were recorded, as were the scores obtained using a Female Sexual Function Index (FSFI) questionnaire. Sexual dysfunction was noted in 55.9% of patients including problems related to desire (60.2%), arousal (52.7%), lubrication (55.9%), orgasm (51.6%) and satisfaction (58.1%) as well as pain during sexual intercourse (54.8%). Total scores were correlated negatively to age (r= -0.329, p = 0.001) and duration of diabetes (r= -0.246, p = 0.018), while significantly higher in patients with than without hypertension (19.6 vs. 22.4, p = 0.012) and with than without insulin therapy (20.0 vs. 23.7, p = 0.050). Our findings indicate the adverse effects of T2DM on sexual function in 55.9% of women in all domains of sexual response cycle, although this seems to be associated with older age, longer duration of diabetes, insulin and antidepressant therapy, presence of hypertension as well as end-organ complications of neuropathy and coronary artery disease (CAD).
