ABSTRACT
Objective:To explore the clinical characteristics and treatment regimens of adrenal incidentaloma (AI) in children.Methods:Clinical data of 38 children with AI treated in the Department of Urology, Children′s Hospital of Nanjing Medical University from December 2016 to October 2021 were retrospectively analyzed.A total of 38 children were divided into neonatal group and non-neonatal group according to their age at first diagnosis.The neonatal group had 7 males and 9 females patients, of whom 7 cases were detected with AI during prenatal examinations, 9 cases were diagnosed postnatally.Four children in neonatal group had AI in the left adrenal gland and 12 cases in the right, with the maximum diameter of tumor (MDT) ranging from 16-48 mm.In the non-neonatal group, there were 14 males and 8 females patients aged 7 months and 1 day to 12 years and 1 month, and the MDT was 29-131 mm.Paired t test was used to compare the age and MDT of benign and malignant tumors. Results:In the neonatal group, 3 patients were surgically treated, with 2 cases and 1 case of neuroblastoma and teratoma confirmed by postoperative histology, respectively.The remaining 13 patients in the neonatal group were followed up for 1-31 months, with 8 cases and 5 cases of complete remission and significantly decreased tumor volume, respectively.In the non-neonatal group, there were 3, 9 and 10 patients received open biopsy, laparoscopic adrenalectomy, and open adrenalectomy, respectively.Of these 22 surgically treated cases, 8 cases had a benign lesion, including ganglioneuroma ( n=4), adrenocortical adenoma ( n=1), adrenal cyst ( n=1), teratoma ( n=1), and pheochromocytoma ( n=1); while 14 cases had a malignant lesion, including neuroblastoma ( n=8), ganglioneuroblastoma ( n=5), and adrenocortical carcinoma ( n=1). The mean age of patients with malignant tumors was significantly younger than those with benign tumors[(38.94±35.44) months vs.(95.89±41.43) months, t=3.63, P=0.001]. The mean MDT in malignant tumors was significantly longer than that of benign tumors[(64.43±25.20) mm vs.(41.44±15.66) mm, t=2.45, P=0.023]. Conclusions:AI in children has a high risk of malignancy.Therefore, more detailed examinations are needed to detect tumor markers and endocrinological parameters, and imaging tests such as non-contrast and CT examination should be performed as early as possible.AI in children is predominantly neuroblastic tumors.For non-neonatal patients, surgery should be performed as early as possible.For AI found in the neonatal period and prenatal examination, expectant management is feasible if the tumor is relatively small and limited to the adrenal gland without distant metastases.
ABSTRACT
ABSTRACT Visceral leishmaniasis (VL) is mainly caused by Leishmania (Leishmania) donovani and Leishmania (L.) infantum; however, other Leishmania species have been associated with VL. We report a case of a patient simultaneously diagnosed with VL caused by Leishmania (L.) amazonensis and Hodgkin's lymphoma. After treatment with liposomal amphotericin B and chemotherapy, the patient presented a clinical cure. This case report reinforces the hypothesis that other Leishmania species can cause visceral lesions mainly related to immunosuppression.
ABSTRACT
ABSTRACT Objective To determine whether the size of thyroid nodules in ACR-TIRADS ultrasound categories 3 and 4 is correlated with the Bethesda cytopathology classification. Methods Thyroid nodules (566) subclassified as ACR-TIRADS 3 or 4 were divided into three size categories according to American Thyroid Association guidelines. The frequency of different Bethesda categories in each size range within ACR-TIRADS 3 and 4 classifications was analyzed. Results Most nodules in both ACR-TIRADS classifications fell in the Bethesda 2 category, regardless of size (90.8% and 68.6%, ACR-TIRADS 3 and 4 respectively). The prevalence of Bethesda 6 nodules in the ACR-TIRADS 4 group was 14 times higher than in the ACR-TIRADS 3 group. There were no significant differences between nodule size and fine needle aspiration biopsy classification in any of the ACR-TIRADS categories. Conclusion Size does not appear to be an important criterion for indication of fine needle aspiration biopsy in thyroid nodules with a high suspicion of malignancy on ultrasound examination.
ABSTRACT
@#Minimally invasive surgery (MIS) is currently mainly used for the treatment of early thymic tumors. In recent years, minimally invasive thymic surgery has been rapidly promoted at home and abroad. However, because of the low incidence of thymic tumors, the unbalanced experience of doctors, there are still many issues worthy of discussion in MIS. Standard MIS must follow similar oncological and resection principles. This paper involves the definitions of minimally invasive thymic surgery and general principles that should be adhered to when performing MIS for thymic malignances.
ABSTRACT
Surgery is the most important therapy for thymic malignances. The last decade has seen increasing adoption of minimally invasive surgery (MIS) for thymectomy. MIS for early stage thymoma patients has been shown to yield similar oncological results while being helpful in minimize surgical trauma, improving postoperative recovery, and reduce incisional pain. Meanwhile, With the advance in surgical techniques, the patients with locally advanced thymic tumors, preoperative induction therapies or recurrent diseases, may also benefit from MIS in selected cases.

Objective To summarize the imaging features of computed tomography (CT)and magnetic resonance imaging (MRI) combined with multi-technology imaging and compare its effects in the preoperative evaluation of malignant perihilar biliary obstruction.Methods The clinical data of 20 patients receiving CT and MRI who were diagnosed with malignant perihilar biliary obstruction by pathological examination at the Wuxi Second People's Hospital between January 2008 and April 2014 were retrospectively analyzed.Patients receiving CT combined with negative-contrast CT cholangiopancreatography (nCTCP) and computed tomography angiography (CTA) were allocated into the CT group,and patients receiving MRI combined with magnetic resonance cholangiopancreatography (MRCP) and magnetic resonance angiography (MRA) were allocated into the MRI group.The images of the 2 groups were analyzed by 2 independent reviewers.The classification of malignant perihilar biliary obstruction,hepatic artery and portal vein invasions and lymph node and organ metastases were evaluated respectively,and then the results of evaluation were compared with the results of surgery and pathological examinations.The comparison between the accuracy of imaging examination in the 2 groups and accuracy of perihilar biliary obstruction classification were analyzed by the chi-square test.The comparison of evaluating accuracy (sensitivity and specificity) among vascular invasion and lymph node and organ metastases were done by the receiver operating characteristic (ROC) curve analysis,and the comparison of its accuracy were done by the z-score test.Results The imagings of bile duct involvement of the 2 groups showed that there were irregular thickening bile duct wall combined with retrograde intrahepatic bile duct dilatation.The symptoms of vascular invasion included the stricture and occlusion of blood vessels or more than half of vascular contact surface with tumor.The symptoms of lymph node metastasis included the enlarging short-axis or round-like circular enhanced lesions.The symptoms of organ involvement included the unclear boundary of lesions or low-density necrotic foci within organ.All the 20 patients underwent the surgical treatment,including 13 patients with hilar cholangiocarcinoma and 7 patients with gallbladder carcinoma.Hepatic artery invasions were detected in 5 patients,portal vein invasions in 10 patients,lymph node metastases in 10 patients and organ metastases in 4 patients.The cases of classification of perihilar biliary obstruction,hepatic artery invasion,portal vein invasion,lymph node metastasis and organ metastasis which were evaluated respectively by reviewer 1 and 2 were 18/18,19/18,18/18,17/16 and 18/19 in the CT group and 17/16,14/13,17/16,15/14 and 19/18 in the MRI group.The imaging of the 2 groups were compared with the evaluating accuracies of classification of malignant hilar biliary obstruction,hepatic artery and portal vein invasions,lymph node and organ metastases in the 2 groups,showing no significant differences (x2=12.593,8.889,z=1.823,1.956,0.462,0.817,0.977,0.751,0.233,1.403,P＞0.05).Conclusion CT and MRI for malignant hilar biliary obstruction had the same imaging features,meanwhile,they can provide an equivalent performance in the classification of malignant hilar biliary obstruction,hepatic artery and portal vein invasions and lymph node and organ metastases.
