Oxaliplatin but Not Irinotecan Impairs Posthepatectomy Liver Regeneration in a Murine Model
Introduction. We examined the murine hepatectomy model of liver regeneration (LR) in the setting of neoadjuvant chemotherapy. Methods. C57BL/6 mice were randomized to receive neoadjuvant intraperitoneal (IP) injections of a control, oxaliplatin (15 mg/kg), or irinotecan (100 mg/Kg or 250 mg/Kg) solution. Hepatectomy (70%) was performed 14 days after the final IP treatment. Animals were sacrificed at postoperative day (D) 0, 1, 2, 3, and 7. Liver remnants and serum were collected for analysis. T-tests for independent samples were used for statistical comparisons. Results. For oxaliplatin, percent LR did not differ at D1 or D2 but was significantly less at D3 (89.0% versus 70.0%, P = 0.048) with no difference on D7 (P = 0.21). Irinotecan-treated mice at both dose levels (100 mg/Kg and 250 mg/Kg) showed no significant differences in LR. BrdU incorporation was significantly decreased in oxaliplatin-treated animals (D1,2,3). Conclusions. Neoadjuvant oxaliplatin but not irinotecan impairs early LR in a posthepatectomy murine model which correlates with decreased DNA synthesis

Challenges and Pitfalls in the Management of Parathyroid Carcinoma: 17-Year Follow-Up of a Case and Review of the Literature
A 29-year-old man presented to his primary care physician with nausea, severe weight loss and muscle weakness. He had a hard, fixed neck swelling. He was severely hypercalcaemic with 10-fold increased parathyroid hormone (PTH) concentrations. A diagnosis of primary hyperparathyroidism was established and the patient was referred for parathyroidectomy. At neck exploration, an enlarged parathyroid gland with invasive growth into the thyroid gland was found and removed, lymph nodes were cleared and hemithyroidectomy was performed. A suspected diagnosis of parathyroid carcinoma was confirmed histologically. Serum calcium and PTH levels normalised post-operatively, but hyperparathyroidism recurred within 3 years of surgery. Over the following 17 years, control of hypercalcaemia represented the most difficult challenge despite variable success achieved with repeated surgical interventions, embolisations, radiofrequency ablation of metastases and treatment with calcimimetics, bisphosphonates and haemodialysis using low-dialysate calcium. In this paper, we report the challenges and pitfalls we encountered in the management of our patient over nearly two decades of follow-up and review recent literature on the topic

Research on Toxocara Canis antibodies obtained from patients with eosinophilia
Background: Eosinophils may suggest the presence of a great variety of anomalies whereupon allergies, malignancies, certain tissue disorders, idiopathic hypereosynophilic syndrome and parasitic infections (with the exception of protozoons) can be cited as a few. Although the clinical manifestations may differ, the eosinophils level is quite an important data in cases related to the helminth infections. Similarly, in parasitic infections related to larva migrans (visceral, cutaneous, ocular), the eosinophils level is again a primary indicator and its evident cause is the roundworm Toxocara spp. Aim: The aim of this study was to evaluate the significance characteristics of Toxocara spp. in patients with eosonophilia. Materials and Methods: In our study, serums were collected from 93 patients of various age groups with eosonophilia (10% and above) while visiting Istanbul University Medical Faculty due to various complaints. Results: Serum samples were treated with Toxocara IgG ready ELISA kit and Toxocara western blot IgG ready kit. Based on the ELISA method; out of 93 patients, 30 patients (32.3%) were positive. Western blot technique; 45 (48.4%) were positive with anti-toxocara IgG antibodies. Conclusion: Results point out to western blot technique being more sensitive and superior on a scale of (P < 0.0001) when compared with the ELISA method
