The Global Burden of Alveolar Echinococcosis

Human alveolar echinococcosis (AE), caused by the larval stage of the fox tapeworm Echinococcus multilocularis, is amongst the world's most dangerous zoonoses. Transmission to humans is by consumption of parasite eggs which are excreted in the faeces of the definitive hosts: foxes and, increasingly, dogs. Transmission can be through contact with the definitive host or indirectly through contamination of food or possibly water with parasite eggs. We made an intensive search of English, Russian, Chinese and other language databases. We targeted data which could give country specific incidence or prevalence of disease and searched for data from every country we believed to be endemic for AE. We also used data from other sources (often unpublished). From this information we were able to make an estimate of the annual global incidence of disease and disease burden using standard techniques for calculation of DALYs. Our studies suggest that AE results in a median of 18,235 cases globally with a burden of 666,433 DALYs per annum. This is the first estimate of the global burden of AE both in terms of global incidence and DALYs and demonstrates the burden of AE is comparable to several diseases in the neglected tropical disease cluster

Early Oncologic Failure after Robot-Assisted Radical Cystectomy: Results from the International Robotic Cystectomy Consortium

PURPOSE: We sought to investigate the prevalence and variables associated with early oncologic failure. MATERIALS AND METHODS: We retrospectively reviewed the IRCC (International Radical Cystectomy Consortium) database of patients who underwent robot-assisted radical cystectomy since 2003. The final cohort comprised a total of 1,894 patients from 23 institutions in 11 countries. Early oncologic failure was defined as any disease relapse within 3 months of robot-assisted radical cystectomy. All institutions were surveyed for the pneumoperitoneum pressure used, breach of oncologic surgical principles, and techniques of specimen and lymph node removal. A multivariate model was fit to evaluate predictors of early oncologic failure. The Kaplan-Meier method was applied to depict disease specific and overall survival, and Cox proportional regression analysis was used to evaluate predictors of disease specific and overall survival. RESULTS: A total of 305 patients (22%) experienced disease relapse, which was distant in 220 (16%), local recurrence in 154 (11%), peritoneal carcinomatosis in 17 (1%) and port site recurrence in 5 (0.4%). Early oncologic failure developed in 71 patients (5%) at a total of 10 institutions. The incidence of early oncologic failure decreased from 10% in 2006 to 6% in 2015. On multivariate analysis the presence of any complication (OR 2.87, 95% CI 1.38–5.96, p = 0.004), pT3 or greater disease (OR 3.73, 95% CI 2.00–6.97, p <0.001) and nodal involvement (OR 2.14, 95% CI 1.21–3.80, p = 0.008) was a significant predictor of early oncologic failure. Patients with early oncologic failure demonstrated worse disease specific and overall survival (23% and 13%, respectively) at 1 and 3 years compared to patients who experienced later or no recurrences (log rank p <0.001). CONCLUSIONS: The incidence of early oncologic failure following robot-assisted radical cystectomy has decreased with time. Disease related rather than technical related factors have a major role in early oncologic failure after robot-assisted radical cystectomy

Development of a patient and institutional-based model for estimation of operative times for robot-assisted radical cystectomy: results from the International Robotic Cystectomy Consortium

OBJECTIVES: To design a methodology to predict operative times for robot-assisted radical cystectomy (RARC) based on variation in institutional, patient, and disease characteristics to help in operating room scheduling and quality control. PATIENTS AND METHODS: The model included preoperative variables and therefore can be used for prediction of surgical times: institutional volume, age, gender, body mass index, American Society of Anesthesiologists score, history of prior surgery and radiation, clinical stage, neoadjuvant chemotherapy, type, technique of diversion, and the extent of lymph node dissection. A conditional inference tree method was used to fit a binary decision tree predicting operative time. Permutation tests were performed to determine the variables having the strongest association with surgical time. The data were split at the value of this variable resulting in the largest difference in means for the surgical time across the split. This process was repeated recursively on the resultant data sets until the permutation tests showed no significant association with operative time. RESULTS: In all, 2 134 procedures were included. The variable most strongly associated with surgical time was type of diversion, with ileal conduits being 70 min shorter (P 66 RARCs) was important, with those with a higher volume being 55 min shorter (P < 0.001). The regression tree output was in the form of box plots that show the median and ranges of surgical times according to the patient, disease, and institutional characteristics. CONCLUSION: We developed a method to estimate operative times for RARC based on patient, disease, and institutional metrics that can help operating room scheduling for RARC

Cystic ovarian teratoma with intracystic floating globules

Ovarian cystic teratomas are cystic fatty tumors that are often found in patients of reproductive age, and the diagnosis can be easily made radiologically. We present a case of postmenopausal ovarian cystic teratoma with an unusual radiologic appearance of intracystic floating globules

An unusual mesenteric paraganglioma producing human chorionic gonadotropin

Adrenal and extra-adrenal paragangliomas are uncommon neoplasms arising from the parenchymal cells of paraganglia. The presenting symptoms are mostly due to excess catecholamine secretion. Extra-adrenal paragangliomas are mostly localized in the superior para-aortic region of the abdomen. Mesenteric paragangliomas are very rare. We report an unusual case of mesenteric paraganglioma producing human chorionic gonadotropin (hCG). To the best of our knowledge, this is the first case report describing hCG secretion in an extra-adrenal paraganglioma

Skull metastasis of follicular thyroid carcinoma

Metastasis of a follicular thyroid carcinoma (FTC) to the skull is very rare. We present a case of solitary lytic skull metastasis of a FTC in a 30-year-old woman. The patient presented with bulging on the left side of the head. Neuro-imaging techniques showed a lesion with an osteolytic component in the left frontal region. After a left frontal craniectomy the tumour was removed totally. The histopathological examination revealed a well-differentiated FTC metastasis and a complete total thyroidectomy was subsequently performed. The patient was given thyroid-stimulating hormone (TSH) suppression therapy followed by whole body iodine-131 (I-113) internal radiation

Thyroid hemiagenesis with multinodular goiter: a case report and review of the literature.

Thyroid hemiagenesis is a very rare abnormality, in which one thyroid lobe fails to develop. Most of the patients diagnosed have an associated thyroidal disease. The true prevalence of thyroid hemiagenesis is not known, but it is estimated to be 0.02% in normal children. We report a forty-five year-old female patient with a multinodular goiter in left lobe, associated with hemiagenesis of right lobe and isthmus
