Objective. Thyroid fine-needle aspiration (FNA) and cytology is a reliable diagnostic method used in the assessment of malignancy when evaluating thyroid nodules, in conjunction with clinical and ultrasonographic findings. The aim of this study is to compare clinical, ultrasonographic, cytological and histopathological findings in children who underwent thyroid FNA. Methods. Subjects comprised 80 patients (52 female) aged 13.7±2.8 years at the time of FNA who where evaluated for thyroid nodules. Clinical, ultrasonographic and cytological findings of patients were evaluated retrospectively. Results. Autoimmune thyroiditis was present in 30% and history of radiotherapy to the head or neck in 10%. The cytological diagnosis of patients included: inadequate or hemorrhagic sample in 10%; benign in 42.5%; atypia or follicular lesion of undetermined significance (AUS/FLUS) in 15%; suspicion of follicular neoplasia (SFN) in 7.5%; suspicion of malignancy (SM) in 8.8%; and malignant in 16.3%. Thirty-seven patients underwent thyroidectomy. Malignancy rates for histopathologic follow-up were 75%, 85.7% and 100% for SFN, SM and malignant categories, respectively. Only one benign and two AUS/FLUS FNAs were found to be malignant on histopathological examination. Among patients who had received radioiodinetherapy, 87.5% had malignancy. In this study, the sensitivity of FNA was 96%, specificity 50%, positive predictive value 90.9%, negative predictive value 75%, and diagnostic value of FNA was 89.2%. Conclusion. Thyroid FNA results were highly compatible with histopathological examination. Sensitivity, positive predictive value and diagnostic value of FNA were high. [ABSTRACT FROM AUTHOR]

Purpose: The objective of this study was to characterize the electrophysiological characteristics of nonrecurrent inferior laryngeal nerves (NRILNs) that were dissected via intraoperative neuromonitoring (IONM) and concomitant vascular anomalies in patients with NRILNs., Methods: A retrospective analysis was conducted on 7865 patients who underwent thyroidectomy with IONM at three tertiary referral centers. The study included 42 patients in whom an NRILN was detected. IONM data and postoperative vocal cord (VC) examinations were recorded for all patients. The absence of an initial vagal EMG response and/or a short (<3.5 ms) latency period during the initial vagal stimulation or the inability to identify the RLN within the Beahrs triangle was considered highly suspicious for the presence of an NRILN. Postoperative cross-sectional imaging was performed in 36 out of 42 patients to assess any concurrent vascular anomalies., Results: The prevalence of NRILN was 0.53%. An NRILN was suspected due to EMG findings in 32 (76%) patients and the inability to identify the RLN within the Beahrs triangle in the remaining 10 (24%) patients. The mean right VN latency period was 3.05 ± 0.15 ms. The V1 latency period of the right VN was shorter than 3.5 ms in 39 (93%) and longer than 3.5 ms in 3 (7%) patients. One of these three patients with latency>3.5ms had a large mediastinal goiter. Transient VC paralysis occurred in one (2.4%) patient. Of the 36 patients with postoperative imaging data, 33 (91.4%) had vascular anomalies. All 33 patients had aberrant right subclavian arteries, and 13 (39.4%) also had accompanying additional vascular anomalies., Conclusion: The NRILN is an anatomical variation that increases the risk of nerve injury. Observation of an absent EMG response and/or a short latency period during the initial vagal stimulation facilitates the detection of an NRILN at an early stage of thyroidectomy in the majority of patients., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The author(s) declared that they were an editorial board member of Frontiers, at the time of submission. This had no impact on the peer review process and the final decision., (Copyright © 2024 Sormaz, Iscan, Tunca, Kostek, Aygun, Matlim Ozel, Soytas, Poyanli, Sari, Uludag and Giles Senyurek.)

Background: Adrenal gland injury (AGI) associated with trauma is an uncommon and often overlooked condition. This study aimed to evaluate the frequency of AGI in individuals with severe trauma injuries and investigate the outcomes of patients with AGI., Methods: All patients admitted to a tertiary trauma referral center under the trauma protocol who had a computed tomography (CT) scan between January 2012 and January 2023 were analyzed retrospectively. Patients who were dead on arrival and patients with incomplete data were excluded. They were classified into two main groups, adult and pediatric, and further subcategorized by the presence or absence of radiologically evident AGI. Demographic data, mechanism of injury, injury severity scores (ISS), presence of concurrent abdominal injury, and 30-day mortality rates were compared. A separate analysis was performed for factors affecting mortality rates., Results: A total of 1,253 patients were included: 950 adults and 303 pediatric patients. In the adult group, AGI was detected in 45 (4.7%) patients and was more commonly associated with the following mechanisms of injury: motor vehicle accidents (26.7% vs. 14.3%) and pedestrian accidents (37.8% vs. 15.5%). Injury to the right side was more common (55.6%). Patients with AGI had higher rates of concurrent liver (17.8% vs. 3.9%), spleen (11.1% vs. 3.6%), and kidney injuries (15.6% vs. 1.3%). In the pediatric population, AGI was detected in 30 patients (14.8%), a significantly higher rate compared to the adult group. Similar to the adult group, AGI was more commonly associated with concurrent abdominal injuries and had a right-sided dominance (60%), but the rate of concurrent abdominal injuries was higher in the pediatric group (80% vs. 46%). The 30-day mortality was significantly higher in both adult and pediatric AGI groups compared to patients without AGI (adult: 15.6% vs. 2.9%, pediatric: 10% vs. 1.8%). In patients with AGI, major head and neck injuries and chest injuries were associated with mortality., Conclusion: Adrenal gland injuries due to trauma are not uncommon. They are usually associated with blunt trauma and other concurrent abdominal organ injuries. The major contributors to mortality in patients with AGI were major head and neck injuries and chest injuries.

Adrenal schwannomas are rare benign tumors with no specific imaging and laboratory findings to diagnose preoperatively. Due to the limited number of cases in the literature, clinical, imaging, and pathological findings are presented in this study. Case 1 is a 61-year-old woman patient who has a 31-mm mass in the right adrenal gland. This mass was nonfunctional; in imaging studies, this mass had a cystic necrotic component, and high 18-fluorodeoxyglucose (FDG) uptake was seen. There was no metaiodobenzylguanidine (MIBG) uptake. Laparoscopic transabdominal right adrenalectomy was performed, and the pathology result was consistent with adrenal schwannomas. Case 2 is a 63-year-old man patient who presented with a 38-mm mass in the left adrenal gland. This mass was nonfunctional and similar to that in Case 1; this mass had a cystic component. Laparoscopic transabdominal left adrenalectomy was performed. The diagnosis of adrenal schwannoma with degeneration was revealed. Case 3 was a 72-year-old woman patient admitted to the hospital for a 125-mm left adrenal mass. Similar to Case 1, this mass also had a cystic necrotic component in imaging studies. High FDG uptake was seen, and the patient underwent conventional adrenalectomy due to the suspicion of malignancy. After pathological evaluation, a diagnosis of adrenal schwannoma was made. A main diagnostic challenge in adrenal schwannomas is the preoperative diagnosis. These masses have no pathognomonic finding or specific hormonal function. Imaging findings of these masses may increase the suspicion of malignancy, which may affect decisions for surgery and the surgical technique., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Kostek, Unlu, Caliskan, Aygun, Iscan, Dural, Sormaz, Tunca, Giles Senyurek and Uludag.)

Purpose: This study was performed to compare the real-time electromyographic (EMG) changes and the rate of recurrent laryngeal nerve (RLN) injury in craniocaudal and lateral approaches for RLN during thyroidectomy., Methods: One hundred twelve and 86 patients were prospectively randomized to receive lateral (group 1) or craniocaudal (group 2) approach to RLN, respectively, under continuous intraoperative nerve monitoring., Results: Loss of signal (LOS) occurred in 7 (2.0%) of 356 nerves at risk (NAR). LOS was significantly associated with repeated adverse EMG changes and presence of RLN entrapment at the ligament of Berry (LOB), which was accompanied by other clinicopathological or anatomical features, such as tubercle of Zuckerkandl (TZ), extralaryngeal branching, hyperthyroidism, autoimmune thyroid disease (ATD), or thyroid lobe volume of >29 cm 3 (P = 0.001 and P = 0.030, respectively). The rate of repeated adverse EMG changes and LOS in the NARs with LOB entrapment accompanied by other clinicopathological and anatomical features was higher in group 1 vs. group 2 (11.1% vs. 2.2%, respectively and 9.7% vs. 0%, respectively; P = 0.070). The total rate of vocal cord palsy (VCP) was significantly higher in group 1 than in group 2 (P = 0.005). The rate of permanent VCP showed no significant difference between the 2 groups., Conclusion: The craniocaudal approach to the RLN is safer than the lateral approach in the RLNs with entrapment at the LOB accompanied by other features, such as TZ, extralaryngeal branching, hyperthyroidism, ATD, or high thyroid lobe volume., Competing Interests: Conflict of Interest: No potential conflict of interest relevant to this article was reported., (Copyright © 2022, the Korean Surgical Society.)

Metastasis is the second most common type of adrenal gland mass. In patients undergoing follow-up for nonadrenal malignancy, adrenalectomy is performed when metastasis to adrenal gland is suspected on the basis of positron emission tomography-computed tomography (PET-CT) imaging. This study investigated the efficacy of PET-CT in the discrimination of metastatic lesions from nonmetastatic lesions in the adrenal glands. In this multicentric study, data was collected from enrolled centers. Forty-one patients who underwent surgery for suspected adrenal metastases were evaluated retrospectively. The following data types were collected: demographic, primary tumor, maximum standardized uptake value of adrenal mass (a-SUVx) and detectability in computed tomography and/or magnetic resonance imaging, and specimen size and histopathology. Six patients were excluded due to unavailability of PET-CT reports and 4 for being primary adrenal malignancy. The rest were divided into 2 groups (metastatic: n = 17, 55% and nonmetastatic: n = 14, 45%) according to histopathology reports. There was no statistical difference between the analyzed values, except the a-SUVx (P < .05). The a-SUVx cutoff value was defined as 5.50 by receiver operating characteristic curves and compared with literature. There was no statistical difference when each group was divided as low and high (P > .05). It was found that PET-CT was able to discriminate metastatic lesions from primary benign lesions (P = .022). PET-CT can discriminate primary benign lesions and metastatic lesions by cutoff 5.5 value for a-SUVx., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2022 the Author(s).

Objective: This study aimed to evaluate the role of risk stratification by the American Thyroid Association (ATA) pediatric thyroid cancer risk levels and BRAF V600E mutation to predict the response to treatment in papillary thyroid cancer (PTC) patients ≤18 years old., Methods: Clinical outcomes during a median period of 6 (2-21.8) years were assessed in 70 patients, according to ATA pediatric risk stratification, BRAF V600E mutation status, and dynamic risk stratification (DRS) at final follow-up., Results: Of 70 patients, 44 (63%), 14 (20%), and 12 (17%) were classified initially as low-, intermediate-, and high-risk, respectively. BRAF V600E mutation analysis data was available in 55 (78.6%) patients, of whom 18 (32.7%) had the BRAF V600E mutation. According to the final DRS, 61 (87%), two (3%), six (9%), and one (1%) patients were classified as an excellent, incomplete biochemical, incomplete structural, and indeterminate response, respectively. All ATA low-risk patients showed excellent response to treatment, whereas the rate of excellent response was 65.4% in intermediate- and high-risk levels (p<0.001). The rates of excellent response in BRAF V600E positive and negative patients were 83% and 92%, respectively (p=0.339). The rate of locoregional recurrence was significantly higher in BRAF V600E positive vs negative patients (33.3% vs 2.7% respectively, p=0.001)., Conclusion: ATA pediatric risk stratification is effective in predicting response to treatment in PTC patients ≤18 years old. The presence of BRAF V600E mutation was highly predictive for recurrence but had no significant impact on the rate of excellent response to treatment at final follow-up.

Objective: The purpose of the study was to evaluate the impact of the coronavirus disease (COVID-19) pandemic on endocrine surgical volumes., Methods: There were periodic surgical restriction sin our country in 2020 due to the pandemic. Endocrine surgery volumes at the Division of Endocrine Surgery, Istanbul Medical Faculty were compared between 2019 and 2020., Results: The surgical volume reduction in 2020 compared to 2019 was 20%, 54.5%, and 40% for thyroid, parathyroid, and adrenal surgery, respectively. Surgical volume for thyroidectomy for benign nodular goiter and parathyroidectomy significantly decreased, whereas adrenal surgery showed no significant difference in 2020 compared to 2019. No significant difference was found in the rates of thyroid cancer and adrenocortical cancer surgery in 2020compared to 2019., Conclusion: The COVID-19 outbreak led to a significant reduction in the annual rates of parathyroidectomy and thyroidectomy for benign goiter, whereas the volume of thyroid cancer and adrenal surgeries were similar to the previous year., Competing Interests: Conflict of Interest: None declared., (Copyright: © 2021 by The Medical Bulletin of Sisli Etfal Hospital.)

The 2019 novel coronavirus disease (COVID-19) was initially seen in Wuhan, China, in December 2019. World Health Organization classified COVID-19 as a pandemic after its rapid spread worldwide in a few months. With the pandemic, all elective surgeries and non-emergency procedures have been postponed in our country, as in others. Most of the endocrine operations can be postponed for a certain period. However, it must be kept in mind that these patients also need surgical treatment, and the delay time should not cause a negative effect on the surgical outcome or disease process. It has recently been suggested that elective surgical interventions can be described as medically necessary, time-sensitive (MeNTS) procedures. Some guidelines have been published on proper and safe surgery for both the healthcare providers and the patients after the immediate onset of the COVID-19 pandemic. We should know that these guidelines and recommendations are not meant to constitute a position statement, the standard of care, or evidence-based/best practice. However, these are mostly the opinions of a selected group of surgeons. Generally, only life-threatening emergency operations should be performed in the stage where the epidemic exceeds the capacity of the hospitals (first stage), cancer and transplantation surgery should be initiated when the outbreak begins to be controlled (second stage), and surgery for elective cases should be performed in a controlled manner with suppression of the outbreak (third stage). In this rapidly developing pandemic period, the plans and recommendations to be made on this subject are based on expert opinions by considering factors, such as the course and biology of the disease, rather than being evidence-based. In the recent reports of many endocrine surgery associations and in various reviews, it has been stated that most of the cases can be postponed to the third stage of the epidemic. We aimed to evaluate the risk reduction strategies and recommendations that can help plan the surgery, prepare for surgery, protect both patients and healthcare workers during the operation and care for the patients in the postoperative period in endocrine surgery., Competing Interests: Conflict of Interest: None declared., (Copyright: © 2020 by The Medical Bulletin of Sisli Etfal Hospital.)

Objective: Although multicentricity is a common feature of thyroid papillary microcancer, it might be difficult to predict this histopathological feature preoperatively., Methods: The records of 306 papillary microcancer patients who underwent thyroidectomy were evaluated. Papillary microcancer was diagnosed as an incidental histopathological finding in 242 (group 1), and by preoperative fine-needle aspiration biopsy in 64 (group 2). Demographic data and histopathological features were compared between the two groups., Results: Age (44 ± 11.4 vs. 43 ± 14 years) and male/female ratio (44/193 vs. 12/52) showed no significant difference between groups 1 and 2 (p > 0.05). Mean tumor size was significantly larger in group 2 (5.2 ± 2.8 mm) compared to group 1 (3.7 ± 2.4 mm) ( p = 0.004). The frequency of thyroid capsule invasion (44 vs. 19%, p = 0.0001), microscopic extrathyroidal invasion (25 vs. 10%, p = 0.004) and multicentricity (44 vs. 29%, p = 0.04), and bilateral lobar involvement (22 vs. 10%, p = 0.0001) was significantly higher in group 2 compared to group 1., Conclusion: Multicentricity with bilateral lobar involvement and aggressive histopathological features are more frequent in papillary microcancer patients diagnosed with preoperative fine-needle aspiration biopsy compared to papillary microcancer diagnosed as postoperative incidental histopathological finding., Competing Interests: The authors have no conflicts of interest to declare., (Copyright © 2019 by S.

Objective: Thyroid fine-needle aspiration (FNA) and cytology is a reliable diagnostic method used in the assessment of malignancy when evaluating thyroid nodules, in conjunction with clinical and ultrasonographic findings. The aim of this study is to compare clinical, ultrasonographic, cytological and histopathological findings in children who underwent thyroid FNA., Methods: Subjects comprised 80 patients (52 female) aged 13.7±2.8 years at the time of FNA who where evaluated for thyroid nodules. Clinical, ultrasonographic and cytological findings of patients were evaluated retrospectively., Results: Autoimmune thyroiditis was present in 30% and history of radiotherapy to the head or neck in 10%. The cytological diagnosis of patients included: inadequate or hemorrhagic sample in 10%; benign in 42.5%; atypia or follicular lesion of undetermined significance (AUS/FLUS) in 15%; suspicion of follicular neoplasia (SFN) in 7.5%; suspicion of malignancy (SM) in 8.8%; and malignant in 16.3%. Thirty-seven patients underwent thyroidectomy. Malignancy rates for histopathologic follow-up were 75%, 85.7% and 100% for SFN, SM and malignant categories, respectively. Only one benign and two AUS/FLUS FNAs were found to be malignant on histopathological examination. Among patients who had received radioiodinetherapy, 87.5% had malignancy. In this study, the sensitivity of FNA was 96%, specificity 50%, positive predictive value 90.9%, negative predictive value 75%, and diagnostic value of FNA was 89.2%., Conclusion: Thyroid FNA results were highly compatible with histopathological examination. Sensitivity, positive predictive value and diagnostic value of FNA were high., Competing Interests: No potential conflict of interest relevant to this article was reported., (©by Acta Endocrinologica Foundation.)

Despite the notable increasing incidence of papillary thyroid microcarcinoma (PTMC), the optimal treatment of the patients with PTMC remains controversial. Because of no consensus about its treatment, the suggested treatment varies from active surveillance alone to total thyroidectomy. Although the 2015 revised American Thyroid Association guideline recommends hemithyroidectomy as the first-line treatment, active surveillance has also been discussed and accepted as another approach for the patients with PTMC. However, the same guideline does not recommend fine needle aspiration biopsy for nodules sized <1 cm, even it is suspicious. In such situation, neither active surveillance nor hemithyroidectomy could be discussed, with a lack of objective cytologic data about the nodules sized <1 cm. In this situation, the decision to perform FNAB to the nodules <1 cm in size depends on the performer of the thyroid ultrasonography. In this invited review, we have discussed the diagnosis and prognostic factors for PTMCs. We have also discussed surgical strategies as the accepted the first-line treatment in patients with PTMC., Competing Interests: Conflict of Interest: None declared., (Copyright: © 2018 by The Medical Bulletin of Sisli Etfal Hospital.)

Objectives: The incidence of papillary microcarcinomas, which are defined as thyroid cancers of <10mm in size, has been increasing in the last decade. Herein, we present internet-based questionnaire results performed by the Turkish Association of Endocrine Surgery with the aim to evaluate the perspective of the management of papillary microcarcinomas in Turkey., Material and Methods: The user-friendly questionnaire consisted of 13 questions in total. These questions mainly addressed the surgical management of nodules and cancer of <1 cm in size. Patient management before, during, and after surgical intervention was also included; additionally, the "active surveillance approach" was questioned., Results: There were 420 responders in total who were of multidisciplinary origin (endocrinologists, surgeons, nuclear medicine specialists, pathologists, and oncologists). Total thyroidectomy was the predominant treatment approach (65%) for the classical type of microcarcinoma limited in one lobe, whereas in cases of microcarcinomas incidentally diagnosed during hemithyroidectomy, complementary surgery approach was advised by 40% of the responders. The responders found capsule invasion (86%) and patient based management (94%) of high importance. The percentage of the responders who recommended radioactive iodine ablation in incidental cancers having no aggressive criteria was 51%. The survey participants that were against routine central dissection in these cases accounted for 73% of the responders. The recommendation of active surveillance (follow-up without any interventional therapy) was limited with 9% responders., Conclusion: The results of the questionnaire demonstrated that there have been various choices in Turkey for the surgical treatment of the papillary microcarcinomas., Competing Interests: Conflict of Interest: The authors has no conflicts of interest to declare.

Background/aim: This study aimed to investigate the role of the mitochondrial apoptotic pathway in benign thyroid nodules., Materials and Methods: Paired samples of nodular and normal tissues were collected from 26 patients with nodular goiters undergoing thyroidectomy. Variable expression of Bcl-2, Bax and Bad genes were evaluated by quantitative PCR., Results: Expression level of Bad gene in nodules was found to be significantly decreased compared to normal tissues (p=0.049). A positive correlation was observed between nodule size and Bad expression levels (correlation coefficient=0.563, p=0.004); and this correlation was stronger in hot nodules (n=18, correlation coefficient=0.689, p=0.003). No significant difference was observed between nodular and normal tissue expressions of Bax and Bcl-2., Conclusion: These results suggest that Bad expression correlates with the size of benign thyroid nodules and also its relatively lower expression in nodules, warrant further investigation., (Copyright© 2018, International Institute of Anticancer Research (Dr. George J.

Background: A thyroidectomy can be performed via a cervical incision in most patients with retrosternal goiter., Aims: To investigate the correlation between the volume of the mediastinal portion of the thyroid gland and the need for an extra-cervical approach for retrosternal goiter., Study Design: Diagnostic accuracy study., Methods: The measurement of craniocaudal length and the volume of the mediastinal component of the thyroid gland on computerised tomography images was performed in 47 patients with retrosternal goiter. Of these 47 patients, 8 (17%) required an extra-cervical approach and were classified as group 1, and 39 (83%) patients that required a cervical incision were classified as group 2. Receiver operating characteristic analysis was performed to determine the cut-off value for the craniocaudal length and the volume of the mediastinal thyroid mass, which significantly correlated with an extra-cervical approach for retrosternal goiter., Results: Reoperative surgery was significantly more frequent in group 1 than in group 2 (50% vs 13%; p=0.03). The craniocaudal length of the mediastinal thyroid gland was significantly longer in group 1 than in group 2 (77±11 mm vs 31±21 mm, respectively; p=0.0001). The volume of the mediastinal component was significantly larger in group 1 compared to group 2 (264±106 cm3 vs 40±41 cm3, respectively; p=0.0001). The receiver operating characteristic curve of craniocaudal length and the volume of the mediastinal component identified ≥66 mm and ≥162 cm3 as the cut-off values with the maximum accuracy, respectively. The craniocaudal length of the thyroid mass below the thoracic inlet ≥66 mm or a volume of the mediastinal portion ≥162 cm3 were significantly associated with an extra-cervical approach (p=0.0001). For predicting an extra-cervical approach, the sensitivity, positive predictive value and negative predictive value of the cut-off value for craniocaudal length was 87.5%, 64% and 97%, respectively. For predicting an extra-cervical approach, the sensitivity, positive predictive value and negative predictive value of the cut-off values for the mediastinal volume were 100%, 89% and 100%, respectively., Conclusion: A thyroid volume of ≥162 cm3 extending below the thoracic inlet was a significant determining factor for an extra-cervical approach, with a negative predictive value for the extra-cervical approach of 100% for retrosternal goiter with smaller volumes. Further studies with an increased number of patients are needed to determine the value of volumetric analysis of retrosternal goiter to predict the need for an extra-cervical approach in retrosternal goiter.

Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver, and extrahepatic metastases are typically found during disease progression. The incidence of adrenal metastasis (AM) from HCC in autopsy series ranges from 4.6 to 12.5%, and it is the second most common site of metastasis after the lungs. To date, there have been few reports of patients who underwent adrenalectomy for isolated AM from HCC after liver transplantation (LT). A woman aged 55 years was referred to our clinic for the evaluation of a right adrenal mass that was detected by abdominal ultrasonography at another center. She had undergone liver transplantation secondary to HCC and acute liver failure due to cryptogenic liver cirrhosis 138 months previously. She had been followed up for 5 years following LT after which she declined to continue with further follow-up. After radiologic and biochemical evaluation, she underwent adrenalectomy and the histopathologic examination revealed a 10 × 8 × 7-cm adrenal mass, which was considered to be an isolated AM from HCC. To our knowledge, this is the first case of isolated AM from HCC in the literature that was diagnosed 138 months after liver transplantation. Isolated AM from HCC after LT is rare and might be detected a long time after LT. Curative surgical resection of isolated metachronous AM from HCC in the absence of disseminated disease might provide for an acceptable disease-free period after adrenalectomy.

This is a case report of a 40-year-old man with an adrenal mass that was found incidentally on routine check-up examination. MRI showed a 30 × 51 × 57 mm cystic-semisolid heterogeneous mass; hormonal functions were within normal limits. Operative removal was planned because of the large size of the mass. Histopathological and immunohistochemical findings were consistent with adenomatoid tumour. The patient was disease-free at 1 year follow-up. We present this case with its radiological and histological characteristics under the review of the literature., (2015 BMJ Publishing Group Ltd.)

Purpose: Concomitant use of chemotherapy and a radiation dose schedule that is more efficient compared to conventional radiotherapy may provide better outcomes in patients with esophageal cancer. This study aimed to assess the efficacy and tolerability of neoadjuvant cisplatin-based chemotherapy and hyperfractionated accelerated radiotherapy regimen in this group of patients., Methods and Materials: A total of 20 newly diagnosed treatment-naïve esophageal cancer patients were included in the study. Neoadjuvant cisplatin and 5-FU were given with 28-day intervals in a total of three courses. Along with the third course of chemotherapy, hyperfractionated accelerated radiotherapy (HART) was given with the following dose schedule: 5760 cGy/36 fr/16 day., Results: All patients could receive the planned RT dose of 5760 cGy. Odynophagia was the most frequent grade III acute toxicity (50%). None of the acute toxicity reactions required treatment discontinuation. Grade III or higher subacute/late toxicity occurred in 10 patients (75%) including 5 deaths, mostly esophageal. Radiologically, 8 patients (40%) had complete response, 8 (40%) had partial response, and 3 (15%) had stable disease, with only 1 patient (5%) having progressive disease. Seven patients underwent surgery. Overall, 8 patients (40%) had local control. The 5 years overall survival rate was 38.1%., Conclusions: Neoadjuvant hyperfractionated accelerated radiotherapy plus chemotherapy may help to target local disease control and increase survival in patients with esophageal cancer. Further studies to improve neoadjuvant and radical chemoradiotherapy dose schedules are warranted for maximum tumor control rates with minimal toxicity.

Objective: We investigated the biochemical and histopathological effects of vitamin C, low-molecular-weight heparin (LMWH), and hypertonic solution on acute necrotizing pancreatitis and on lungs as a terminal organ., Materials and Methods: We included 48 Sprague-Dawley rats in the study, which were divided into six groups, each with eight rats. The rats in group 1 were sacrificed immediately, in order to determine normal reference values for biochemical and histopathological data. Twenty-four hours after giving intraperitoneal L-arginine to the remaining five groups, development of pancreatitis was shown through assessment of amylase and CRP values. Rats in group 2 were sacrificed at the 24th hour and assigned to the control group for biochemical or the histopathological data groups, in which pancreatitis was induced. The rats in the remaining four groups were given intravenous (IV) isotonic NaCl (group 3), IV vitamin C (group 4), subcutaneous LMWH (group 5), IV hypertonic NaCl (group 6) between 24-48 hours. Each group was assessed with respect to amylase, Serum glutamic oxaloacetic transaminase (SGOT), Lactate dehydrogenase (LDH), C-reactive protein (CRP), bicarbonate, base excess (BE), Ca++, ascorbic acid, and leukocyte at hour 72. Additionally, pancreatic and lung tissue was histopathologically evaluated., Results: In the treatment groups, amylase and leukocyte levels at the 72nd hour were found to be significantly lower than at the 24th hour (p<0.05). The most significant decrease in amylase and leukocyte levels was found in group 6, and damage to the pancreas was found to be lowest in groups 4 and 6., Conclusion: We observed that in rats, hypertonic NaCl solution and vitamin C reduced the amount of necrosis in the pancreas.

Objective: When considering abdominal region injuries, the colon is one of the most frequently wounded organs. Due to the septic contents of the colon, failure to treat or improper treatment of colon injuries increases the risk of major complications and may result in death. The aim of our study is a retrospective evaluation of colon injury cases over a 5-year period., Materials and Methods: Forty-nine patients with a diagnosis of colon injury were included in the study. The cause of colon injury, injured area, Flint colon injury score, additional organs injured, type of surgical procedure performed, postoperative complications and mortality were evaluated., Results: The most frequent cause of colon injury was cutters (57.2%), followed by firearms (36.7%). The left colon was the most common site of injury (40.8%), followed by the transverse (28.6%) and right colon (20.4%). Primary treatment or resection and primary anastomosis were performed on 38 patients (77.6%), while primary treatment and proximal decompression colostomy were performed on 11 patients (22.4%). Eighteen of the patients (36.7%) experienced major postoperative complications, and 6 patients (12.2%) died., Conclusion: The morbidity and mortality of colonic injuries can be reduced by rapid patient transportation, good operational experience, use of wide spectrum antibiotics and postoperative care in an intensive care unit.

Aim: To assess the efficacy and safety of ultrasound guided percutaneous cholecystostomy (PC) in the treatment of acute cholecystitis in a well-defined high risk patients under general anesthesia., Methods: The data of 27 consecutive patients who underwent percutaneous transhepatic cholecystostomy for the management of acute cholecystitis from January 1999 to June 2003 was retrospectively evaluated. All of the patients had both clinical and sonographic signs of acute cholecystitis and had comorbid diseases., Results: Ultrasound revealed gallbladder stones in 25 patients and acalculous cholecystitis in two patients. Cholecystostomy catheters were removed 14-32 d (mean 23 d) after the procedure in cases where complete regression of all symptoms was achieved. There were statistically significant reductions in leukocytosis, (13.7 x 10(3)+/-1.3 x 10(3) microg/L vs 13 x 10(3)+/-1 x 10(3) microg/L, P < 0.05 for 24 h after PC; 13.7 x 10(3)+/-1.3 x 10(3) microg/L vs 8.3 x 10(3)+/-1.2 x 10(3) microg/L, P < 0.0001 for 72 h after PC), C -reactive protein (51.2+/-18.5 mg/L vs 27.3+/-10.4 mg/L, P < 0.05 for 24 h after PC; 51.2+/-18.5 mg/L vs 5.4+/-1.5 mg/L, P < 0.0001 for 72 h after PC), and fever (38+/-0.35 centigrade vs 37.3+/-0.32 centigrade, P < 0.05 for 24 h after PC; 38+/-0.35 centigrade vs 36.9+/-0.15 centigrade, P < 0.0001 for 72 h after PC). Sphincterotomy and stone extraction was performed successfully with endoscopic retrograde cholangio-pancreatography (ERCP) in three patients. After cholecystostomy, 5 (18%) patients underwent delayed cholecystectomy without any complications. Three out of 22 patients were admitted with recurrent acute cholecystitis during the follow-up and recovered with medical treatment. Catheter dislodgement occurred in three patients spontaneously, and two of them were managed by reinsertion of the catheter., Conclusion: As an alternative to surgery, percutaneous cholecystostomy seems to be a safe method in critically ill patients with acute cholecystitis and can be performed with low mortality and morbidity. Delayed cholecystectomy and ERCP, if needed, can be performed after the acute period has been resolved by percutaneous cholecystostomy.

Idiopathic thrombocytopenic purpura (ITP) is an isolated thrombocyte disease that has no correlation with other causes of clinical thrombocytopenia in adults. About 70% of patients with ITP were successfully treated by medical care and splenectomy, but nearly 30% of ITP patients do not respond to these treatments. The aim of this study is to evaluate the predictive factors that affect the success of treatment in 26 patients with ITP. Thirteen patients with ITP responded to splenectomy (responsive group), whereas 13 other patients were resistant to medical treatment and splenectomy (resistant group). The control group consisted of 13 patients who had undergone posttraumatic splenectomy. Age, sex, spleen weight, the number of follicles per mm(2), and the length of time between diagnosis and splenectomy were retrospectively analyzed. No significant difference was found between the groups with respect to these variables. Mean maximum follicle diameter (MMaFD), mean minimum follicle diameter (MMiFD), and the number and distribution of CD56 (+) cells were evaluated for each spleen specimen. There was no statistical difference in the distribution of CD56 (+) cells between the ITP patients and the control group, but the number of CD56 (+) cells was significantly higher in the control group than in patients with ITP. While MMiFD showed no statistical difference between the groups of ITP patients, a MMaFD of 350 microm and above was significantly more likely in the resistant group than in the other groups. In conclusion, this study has shown that the MMaFD is a significant predictor of the response to splenectomy.
