Objective: It is still controversial whether performing central neck dissection (CND) in addition to total thyroidectomy (TT) increases the risk of complications. In the present study, we aimed to evaluate the effect of CND on the development of complications in differentiated thyroid cancer (DTC) compared to TT. Material and Methods: The data of 186 patients (136 females and 50 males) with a mean age of 48.73 ± 14.78 (range, 17–82) whom were operated for DTC were evaluated retrospectively. The patients were divided into two groups; TT (Group 1) and CND±TT/Completion thyroidectomy±lateral neck dissection (Group 2). Results: There were 117 (91 F, 26 M) patients in Group 1 and 69 (45 F, 24 M) patients in Group 2. Parathyroid auto transplantation (PA) was significantly higher in Group 2 compared to Group 1 (42% vs. 6%) ( p =0.000). Total (58% vs. 21.4%, respectively; p =0.000) and transient hypoparathyroidism (52.2% vs. 20.5%, respectively; p =0.000) were significantly higher in Group 2 than in Group 1, but permanent hypoparathyroidism rates were statistically not significant (5.8% vs. 0.9%, respectively; p =0.064). In the multinomial logistic regression analysis, CND alone was determined as an independent risk factor for increased both total and transient hypoparathyroidism. The relative risk (RR) of CND for total hypoparathyroidism was 5.2 times increased (odds ratio [OR]: 0.192) ( p =0.007), while the RR for transient hypoparathyroidism was 3.5 times increased (OR: 0.285) ( p =0.036). According to the number of nerves at risk, CND was performed in 119 neck side and only thyroidectomy was performed in 253 neck side. Total vocal cord paralysis (VCP) rate (9 [7.6%] vs. 6 [2.4%], respectively) ( p =0.017) and transient VCP rate (7 [6%] vs. 4 [1.6%], respectively) ( p =0.021) in patients who underwent CND were significantly higher compared to those who underwent only thyroidectomy. In multinomial logistic regression analysis performing only CND was an independent risk factor for total VCP, and increased the total VCP RR approximately 5.34 times (OR:0.184; p =0.007). Conclusion: Although CND can be applied without increasing the rates of permanent hypoparathyroidism and VCP compared to TT, it increases the risk of total and transient hypoparathyroidism, total, and transient VCP. Patients undergoing CND should be followed carefully in terms of transient hypoparathyroidism.
V itamin D (Vit D) is a steroid pro-hormone required for many metabolic regulations in the body, especially for bone mineralization and calcium-phosphate homeostasis. [1] In the body, it is found as either 25(OH)D₃ (the storage form) or as 1α, 25(OH)₂D₃ (the active form). Vit D is one of the first vits described, and its first proven effects are on Ca-P balance.Studies in recent years explain the extraskeletal effects of Vit D and its relationship with some malignancies, in ad-dition to its effects on bone mineralization and metabolite balance. It has been shown that low Vit D levels may increase cancer development such as colon, breast, and prostate cancers, and Vit D deficiency is associated with an increased incidence of advanced cancer stage, recurrence and lymph node metastasis in these cancers. It has been reported in current publications that Vit D shows its anticancer effects due to its anti-inflammatory and anti-prolif-Objectives: In the present study, we investigated the effects of Vitamin D (vit D) deficiency on aggressiveness of papillary thyroid cancer (PTC). Methods: Patients with PTC confirmed with pathological examination, whom were operated by a single surgeon between 2012 and 2017, were included in the study. The data of the patients were analyzed retrospectively. Cancers other than PTC, patients with hyperthyroidism and/or using antithyroid drugs were excluded from the study. The patients were classified as four quartiles according to serum Vit D levels; category 1 (<7.1 ng/mL), category 2 (7.2-11.8 ng/mL), category 3 (11.9-23.4 ng/mL) and category 4 (>23.5 ng/mL). Results: A total of 133 patients (103 female, 30 male) with mean age of 46.4±13.6 (17-82) years were included in the study. There was no significant difference between the categories in terms of preoperative Vit D values according to the evaluated tumor aggressiveness characteristics. It was determined that the presence of tumor with a size above 1 cm and T3/4 tumor were not affected by Vit D level. There was no significant difference between Vit D categories regarding the characteristics of aggressiveness such as multicentricity, lymphovascular invasion, central, and lateral metastases. Conclusion: According to our results, serum Vit D levels are not associated with the aggressive tumor characteristics of PTC.
T hyroid cancer has an increasing incidence due to the increase in diagnostic imaging modalities. Papillary thyroid carcinoma (PTC) is the most common differentiated thyroid cancer (DTC). [1] However, the etiology has not been clarified much, except for reasons such as age, a history of radiation to the neck region, and a previous history of PTC, which predispose to DTC. [2] Thyroid-stimulating hormone (TSH) is the main regulator and growth factor of the thyroid. Since it is the major hormone stimulating thyrocytes, increased serum concentrations of TSH have been found to be associated with cancer risk in thyroid nodules. [3,4] The basis of this view is that TSH has an effect on the proliferation of malignantly transformed DTC cells, as well as on thyrocytes. TSH has been Objectives: Thyroid-stimulating hormones (TSHs) are associated with the risk of differentiated thyroid cancer. The relationship between pre-operative TSH levels and aggressive features is unclear. We aimed to evaluate the relationship between pathological features of papillary thyroid carcinoma (PTC) and high TSH levels. Methods: Patients who were operated between 2012 and 2017 and who were found to have PTC in their pathology were included in the study. The relationship between TSH and the features of tumor aggressiveness was evaluated in the patients. Results: Of the 132 patients, TSH level was significantly higher in those with lymphovascular invasion than those without (p=0.048), in those with central metastases than in those without (p=0.014), and in those with extrathyroidal spread than in those without (p=0.003). When patients were categorized into four 25% quartiles according to TSH (mUI/mL) level; the rate of extrathyroidal invasion increased as the TSH level increased, and the level was significantly higher in quartile 1 than the others, with significant difference (p=0.030). Conclusion: Pre-operative increase in TSH level is associated with an increased risk of extrathyroidal spread and central lymph node metastasis. TSH level may be a pre-operative valuable predictive factor for patients' risk of central metastasis.
Objectives: Hypocalcemia is the most common complication and acute parathyroid gland insufficiency is the main cause of it after thyroidectomy. In this study, we aimed to evaluate the relationship between the recovery time of parathyroid gland function and patient characteristics, preoperative and postoperative electrolyte changes, and intraoperative parathyroid findings in patients with postoperative hypoparathyroidism. Methods: Patients who underwent total thyroidectomy (TT) with or without central neck dissection ± lateral neck dissection with a parathyroid hormone (PTH) value of <15 pg/mL within the postoperative 4th hour were included in this study. Postoperative calcium level of <8mg/dL was defined as biochemical hypocalcemia and a PTH value of <15 pg/mL was defined as hypoparathyroidism. The patients were divided into three groups according to the time of PTH recovery (>15 pg/mL); within the first 24 hours, between one day and 30 days, after 30 days, respectively. Results: One hundred eleven patients (mean age, 49.3±14.4 years) consisted of Groups 1, 2 and 3, including 19 (16F, 3M), 67 (54F, 13M) and 25 (19F, 6M), respectively. Vitamin D deficiency rates for Groups 1, 2, 3 were 41.7%, 53.1% and 88.2%, respectively (p=0.018). Postoperative day 0 PTH values were 11.69±2.79pg/mL, 6.92±3.45 pg/mL, 4.99±2.36 pg/mL, (p<0.001). Biochemical hypocalcemia rates of Groups 1, 2, 3 on postoperative day 1 were 15.8%, 53.7%, 64%, (p=004) respectively, and calcium values were 8.68±0.67 mg/dL, 8.15±0.66 mg/dL, 7.75±1 mg/dL, (p=0.014), respectively. Magnesium values on postoperative day 1 and 7 for Groups 1, 2, 3 were 1.85±0.1 mg/dL, 1.77±0.17 mg/dL, 1.64±0.17 mg/dL, (p=0.005), and 1.86±0.16mg/dL, 1.82±0.21mg/dL, 1.59±0.15mg/dL (p=0.001), respectively. PTH values on postoperative day 1 and 7 in Groups 1, 2, 3 were 20.5±6.4 pg/mL, 7.06±4.35 pg/mL, 4.66±3.26 pg/mL (p<0.001), and 31.04±10.54pg/mL, 18.72±13.84pg/mL, 4.55±4.9pg/mL (p<0.0001), respectively. Parathyroid function improved in 106 patients, and permanent hypoparathyroidism developed in five patients (4.5%). Conclusion:Hypoparathyroidism can recover rapidly in the first 24 hours in patients with a PTH value of around 10 pg/mL at postoperative 4th hour. As the number of preserved parathyroids increased, recovery time decreased. In patients with postoperative hypoparathyroidism, postoperative low magnesium levels may be associated with delayed recovery of parathyroid function.
Objectives: Diverticular disease of the colon is a pathology that arises from outward ballooning of the mucosa due to some weakness in the muscle layer. Diverticular disease may range from symptomatic uncomplicated diverticular disease to symptomatic disease with complications, such as acute diverticulitis or diverticular bleeding. Acute colonic diverticulitis occurs in about 10- 25% of patients. Methods: In this study, 134 patients who were admitted to our emergency clinic with complaints of abdominal pain between 2016-2019 and hospitalized with the diagnosis of acute diverticulitis were included. Patients’ sex, age, presence of additional disease, increase in leukocyte and C-reactive protein (CRP), localization of diverticulitis, Hinchey classification, mean length of hospital stay and treatment were evaluated. The effects of these parameters on complications and recurrence were statistically analyzed. Results: The length of hospital stay was statistically significantly associated positively with the Hinchey classification (p<0.001). While 18 patients who were medically treated developed recurrence later, and this rate was statistically significant (p<0.001). When one of the factors, localization, which may play a role in the severity of the disease and recurrence are examined, was evaluated concerning its results in our study, we found that rectosigmoid location is an important factor for recurrence. We found that the localization in the colon and the severity of the disease were effective in the prognosis of acute diverticulitis. Conclusion: We believe that localization and the severity of the disease should be taken into consideration when planning surgery in these patients.
Objectives: In a thyroidectomy, the external branch of the superior laryngeal nerve (EBSLN) is a potential risk during the superior pole dissection due to its close anatomical relationship with the superior thyroid artery and its highly variable anatomy. In this study, we aimed to evaluate the relationship of EBSLN with the superior pole considering Cernea classification and the factors affecting this relationship. Methods: The data of thyroidectomized 126 patients (95 female, 31 male) with 200 neck sides (mean age of 45.6±12.1 years) using intraoperative neuromonitoring (IONM) for the EBSLN exploration were evaluated retrospectively. During the superior pole dissection, the EBSLN course was classified according to Cernea classification after being confirmed with IONM. It was defined as a large goiter in the case of the thyroid lobe volume being >50 cc. The factors influencing the presence of type 2b, which has the highest risk of injury, were evaluated using logistic regression analysis. Results: Of the 200 EBSLNs evaluated, 52 (26%) were type 1, 134 (68%) were type 2a, and 14 (7%) were type 2b. The mean volumes of the resected thyroid lobes were 22±25 cc (min-max: 2-136), 23±20 cc (3-163), and 39±24 cc (3-65) in type 1, 2a and 2b, respectively, which was significantly higher in type 2b (p=0.035). Presence of large goiter rates were 5.8% (n=3), 8.2% (n=11), 64.3% (n=9) in type 1, 2a, and 2b, respectively, and was significantly higher in type 2b (p=0.0001). There was no significant difference between EBSLN Cernea types concerning age, sex, nerve side, presence of cancer and hyperthyroidism. In logistic regression analysis, large goiter was the only independent factor associated with Cernea type 2b. In case of a lobe volume greater than 50 cc, the probability of type 2b presence was approximately 25 times higher (p<0.001, odds ratio: 25.262). Conclusion: Type 2b course of EBSLN is more common in large goiters, and it is 25 times more likely to be seen in the presence of a lobe volume over 50 cc. Thus, it should be considered that the probability of this high-risk course is significantly higher in large goiters.
BackgroundJuvenile idiopathic arthritis (JIA) is the most common systemic disease causing uveitis in childhood, with a prevalence of 10 per 100 000 persons. JIA-associated uveitis is estimated to have a poor prognosis and has a high rate of complications. JIA-associated uveitis can manifest in various forms, depending on the location and severity of the ocular inflammation, as well as on the type of arthritis. The most of JIA patients with uveitis have oligoarthritis. Therefore, other types of JIA are rarely accompanied by uveitis. Topical corticosteroids are the first line therapy, and disease conventional and biologic modifying anti-rheumatic drugs (DMARDs) are used.ObjectivesThe purpose of the present study was to report on the clinical characteristics, ocular complications, treatment, and visual outcome in children with JIA-associated uveitis who were examined in recent years at a single tertiary pediatric rheumatology and ophthalmology center in Turkey.MethodsWe retrospectively analyzed the data of 41 JIA patients (14 males, 27 females).The duration between the initial evaluation and the final visit was recorded as follow-up time. Juvenile idiopathic arthritis was defined according to the International League of Associations for Rheumatology (ILAR) classification criteria. Uveitis was classified according to the SUN classification.Two approaches were utilized to evaluate the change of visual acuity (VA) during the disease course: (i) VA was measured on Snellen chart. The equivalent logarithm of the minimum angle of resolution acuity (logMAR) was calculated and used for analysis.ResultsThe study included 31 patients (57 eyes) of whom 22 (71%) were females. Mean age (±SD) at uveitis diagnosis was 8.42 (±4.13) years (median 8, range: 34 month–17 years) and there was no significant difference between genders. The mean age at jia diagnosis was 8.42 (±4.7), respectively. Nine patients were ≤ 7 years of age at the time of JIA diagnosis. Anterior uveitis (AU) was the most common type, diagnosed in 57 (76%) eyes. All patients had methotrexate, therefore biologic therapy was used in 29/31 patients (93.5%) at the follow up time (infliximab in 12, adalimumab in seventeen, and tocilizumab in three patients) and 9 children (31%) required ≥2 biologics over the follow up period. Thirteen patients switched between infliximab and adalimumab (10 patients switched from infliximab). The reason for treatment switch included treatment failure and treatment-related side-effects (n=3). Systemic and topical steroids treatment were gradually tapered and discontinued in all patients after initiation of biologics. Of the all affected eyes, posterior synechiae (n=24) was the predominant complication on presentation. During the follow-up period new complications were seen in 11 eyes (13%). Posterior synechiea (6 eyes, 7,5%) was the most frequent complication observed followed by cataract (3 eyes, 3,%) and glaucoma (2 eyes, 2,5%) Improvement or preservation of visual acuity (VA) was noted in 77 eyes (%94,3) at the last visit.ConclusionWe re...
Background: Juvenile Idiopathic Arthritis associated Uveitis (JIA-U) represents its most frequent extra-articular manifestation and the main cause of childhood uveitis in in developed countries. The broad variety of outcome measures utilized makes the comparison of the disease course, risk for complications, impairment in visual function, and responses to treatment quite difficult. Objectives: Our aim was to define related and unified outcome measures in JIA-U. Methods: A systematic review between January 2000 and December 2018 was performed to identify studies investigating outcome measures used in JIA-U Results: The initial search identified 8252 articles of which 29 were potentially eligible. Eighteen eligible articles remained in the analysis. A total of 27 studies, including 2 RCTs, were included. Among these studies 12 outcome measures for JIA-U use have been identified (grade of cells in the AC, grade of flare in the AC, VA, amblyopia, structural complications, use and sparing of oral corticosteroids and immunosuppressive drugs, surgery requirement, biomarkers, bilateral disease, JIA persistence, quality of life assessments, uveitis subtype). As regards primary outcome measures, 44% among studies included one or more variables related to disease activity (i.e. grade of flare, grade of cells); 56% included visual function performance (i.e. visual acuity); 68% (17/25) included one or more variables of disease-associated tissue damage or complications (i.e. cataract, amblyopia); 24% included disease features (i.e. bilateral disease; uveitis subtype); 44% included laboratory features (i.e. biomarkers); 8% included JIA features (i.e. persistence of disease); 12% included quality of life (i.e. EYE-Q); 44% included management (i.e. use and sparing of oral corticosteroids and other immunosuppressive drugs; surgery requirement). Conclusion: Our systematic review surveys the heterogeneity around outcome measures related to JIA-U in children, even in RCTs. It does not provide the solution to overcome the heterogeneity in uveitis studies, but it does provide an estimate of the scale of the problems and provides data to inform this important debate; highlighting the requirement to obtain a new consensus regarding a common approach to identify suitable and efficient outcome measures in JIA-U.
