Background: We aimed to evaluate the impact of bupivacaine administration into the surgical field after total thyroidectomy on post-operative pain and analgesic requirement with a double-blind, prospective, clinical and randomized study. Methods: The study was performed between 2010 and 2011. Pain assessment was performed with the visual analog score (VAS). Patients were pre-operatively, randomly divided into two groups to receive either bupivacaine or saline. One group received a 10-mL of bupivacaine solution while the other group was treated with the same volume of 0.9% NaCl through the drain after completion of total thyroidectomy procedure. All patients were anesthetized and operated with the same anesthesia and surgical team. Results: Ninety-one patients (20 males) were included in the study. No patient dropped out of the study during the procedures. No mortality was seen. The VAS scores were significantly lower in the bupivacaine administered group at post-operative minute 30 (3.7±3.2 vs. 5±2.9; P=0.03), hour one (3.04±2.4 vs. 4.2±2.8; P=0.04), and hour eight (1.8±2.04 vs. 3.2±2.1; P=0.005). Thirteen patients required analgesia during their hospital stay in the bupivacaine group while this number was twenty-two in the saline group (P=0.005). Conclusions: Local bupivacaine administration into the surgical field after total thyroidectomy reduces pain and analgesic requirement during the hospital stay.

Skin metastasis of papillary thyroid carcinoma (PTC) is rare. Here, two cases of skin metastases of PTC are presented. Both of the patients were females, one is 83 and the other is 65 years old. The patients were admitted to the hospital with a movable skin lesion on anterior neck region. Free T3 and T4 levels were in normal levels and TSH levels were low in both patients. The 83-year-old patient underwent total thyroidectomy due to papillary thyroid cancer and received ¹³¹I ablation therapy and then thyroid suppression therapy. After the surgery, the patient lived without evidence of disease for 3 years and then skin metastasis occurred. The 65-year-old patient had a total thyroidectomy 5 years ago due to PTC then neck dissection due to metastasis 3 years later and then received ¹³¹I ablation therapy. Thyroid ultrasonography of both patients showed hypoechoic nodules with central vascularization. In the histological examination of both patients, cystic lesions filled with papillary structures were seen. Fine needle aspiration biopsy (FNAB) taken from both patients were papillary carcinoma with solid trabecular pattern. PTC tends to metastasize to regional lymph nodes but distant metastasis is rare. When distant metastasis develops, prognosis of the disease is poor. Therefore, skin metastasis of papillary thyroid cancer is a poor prognostic factor. If the patient does not have a thyroid malignancy history, diagnosis of PTC metastatic to the skin may be difficult since primary skin tumors such as apocrine tumors have similar histopathological features. However, in the presented cases since there was a PTC history, the diagnosis was easier with the help of histopathological examination. Skin metastasis of PTC should be kept in mind when differential diagnosis of atypical skin lesions are made especially in the patients with thyroid malignancy history.

Background: Ankaferd (Ankaferd blood stopper®, ABS) is a recently developed topical hemostatic agent. ABS is a standardized mixture of the plants Thymus vulgaris, Glycyrrhiza glabra, Vitis vinifera, Alpinia officinarum, and Urtica dioica. Through its effects on the endothelium, blood cells, angiogenesis, cellular proliferation, vascular dynamics, and cell mediators; Ankaferd plays a part in inflammation and hemostasis processes. The aim of this experimental study is to assess the effects of ABS on the left colonic anastomoses under normal, septic, and ischemic conditions. Methods: Forty-eight Wistar Albino male rats were divided into six weight-matched equal groups: A, anastomosis in normal condition (n = 8); AA, anastomosis with ABS in normal condition (n = 8); AS, anastomosis in septic condition (n = 8); AAS, anastomosis with ABS in septic condition (n = 8); AI, anastomosis in ischemic condition (n = 8); and AAI, anastomosis with ABS in ischemic condition (n = 8). Blood and tissue samples were taken for the histopathological and biochemical studies after the anastomotic bursting pressures were measured. Results: Higher hydroxyproline levels (p = .048) and angiogenesis (p = .038) were observed in the sepsis-induced rats compared to the control group. The inflammatory activity, fibrosis, and granulation were comparable in all experimental groups. Ankaferd improved the angiogenesis under septic conditions (AAS) when compared to the control group (AI; p = .038). Conclusions: ABS may support anastomotic healing in septic conditions. Topical ABS application controlling the mucosal bleeding at the cut ends of the colon may also improve the anastomotic wound healing by means of increasing mechanical strength and positively affecting angiogenesis. Further studies shall focus on the clinical importance of those findings.
