Bratisl Lek Listy 2021 ;122(5):315-319

Objective: Primary foetal cardiac tumours are rare congenital malformations. They can cause a flow obstruction, arrhythmias and can lead to cardiac failure, hydrops or death. Postnatal management is based on patient´s clinical and hemodynamic impairment. Read More

The benefits of inferolateral transtubercular route on intradural surgical exposure using the endoscopic endonasal transclival approach.

Acta Neurochir (Wien) 2021 Apr 13. Epub 2021 Apr 13.

Department of Neurosurgery, Microsurgical Neuroanatomy Laboratory, Cerrahpasa Medical Faculty, Istanbul University-Cerrahpasa, Istanbul, Turkey.

Background: Surgical access to the ventral pontomedullary junction (PMJ) can be achieved through various corridors depending on the location and extension of the lesion. The jugular tubercle (JT), a surgically challenging obstacle to access the PMJ, typically needs to be addressed in transcranial exposures. We describe the endoscopic endonasal transclival approach (EETCA) and its inferolateral transtubercular extension to assess the intradural surgical field gained through JT removal. Read More

Extremely delayed solitary cerebral metastasis in patient with T1N0M0 renal cell carcinoma after radical nephrectomy: Case report and literature review.

Medicine (Baltimore) 2021 Apr;100(15):e25586

Department of Pathology, Yeungnam University Hospital, Yeungnam University College of Medicine Daegu, Republic of Korea.

Rationale: Although renal cell carcinoma (RCC) is one of the common origins of brain metastasis, few cases of extremely delayed brain metastasis from RCC, more than 10 years after nephrectomy, have been reported. We present a rare case of extremely delayed brain metastasis from RCC, also performed a literature review to increase knowledge of the characteristics for extremely delayed brain metastasis from RCC.

Patient Concerns: A 72-year-old man presented with right-sided hemiplegia and dysarthria. Read More

A rare case of ectopic ACTH syndrome caused by primary renal neuroendocrine tumor.

Endocrinol Diabetes Metab Case Rep 2021 Apr 12;2021. Epub 2021 Apr 12.

Division of Endocrinology and Metabolism, Department of Medicine.

Summary: Ectopic adrenocorticotropic hormone (ACTH) secretion is responsible for 5-15% of Cushing's syndrome (CS). Neuroendocrine tumor (NET) is a common cause of ectopic ACTH syndrome (EAS). However, primary renal NET is exceedingly rare. Read More

Intractable Fractures of the Bilateral Proximal Ulnae After 8 Years of Zoledronate Treatment for Breast Cancer Bone Metastasis.

J Hand Surg Am 2021 Apr 9. Epub 2021 Apr 9.

Department of Orthopaedic Surgery, School of Medicine, Kyoto University, Kyoto, Japan.

Long-term administration of bisphosphonates strongly suppresses osteoclastic bone resorption and rarely causes atypical fractures. This report presents a case of bilateral atypical ulnar fractures, following an 8-year course of zoledronate to treat breast cancer bone metastasis. Nonsurgical treatment for the left ulnar fracture failed, in spite of minimal displacement with callus formation at initial presentation. Read More

Application of Bacterial Nanocellulose in the Cancer Drug Delivery: A Review.

Curr Pharm Des 2021 Apr 12. Epub 2021 Apr 12.

Cellular and Molecular Endocrine Research Center, Research Institute of Endocrine Sciences, Shahid Beheshti University of Medical Sciences, Tehran. Iran.

Bacterial nanocellulose (BNC) is one of the natural biopolymers with unique features, the most important of which are nontoxicity, biocompatibility, high tensile profile, nanofiber structure, and purity. The current review aimed to summarize the latest development in BNC-based biomaterials in cancer drug delivery. The original articles were found by searching key databases including PubMed, Scopus, and Web of Scientific and using key terms such as "bacterial nanocellulose OR bacterial cellulose OR BNC" AND "cancer OR carcinoma OR tumor".

Laminectomy versus Unilateral Hemilaminectomy for the Removal of Intraspinal Schwannoma: Experience of a Single Institution and Review of Literature.

J Neurol Surg A Cent Eur Neurosurg 2021 Apr 12. Epub 2021 Apr 12.

Department of Neurosurgery, Università Politecnica delle Marche, Ancona, Italy.

Background And Study Aims:  Spinal schwannomas are benign slow-growing tumors, and gross total resection is the gold standard of treatment. The conventional surgical approach is laminectomy, which provides a wide working area. Today minimally invasive surgery (MIS) is popular because it is associated with shorter hospital stay, less operative blood loss, minimized tissue traumas and relative postoperative pain, and, and spine surgery, avoidance of spinal instability.

Electrophysiological reactions to intraoperative irritation of the optic nerve. Case report and review of possible mechanisms.

Neurochirurgie 2021 Apr 9. Epub 2021 Apr 9.

Department of Neurosurgery, Meshalkin National Medical Research Centre, Rechkunovskaya str., 15, 630055, Novosibirsk, Russian Federation. Electronic address:

Background: Intraoperative control of optic nerve function conservation during neurosurgical operations currently relies mainly on visual evoked potential monitoring. Unfortunately, this detects peril only when the visual pathways are already compromised, sometimes irreversibly. In contrast, electrophysiological stimulation mapping of the nerves can be a fully preventive measure. Read More

Digital Cholangioscopy-guided Cold Snare Resection of an Inflammatory Intraductal Pseudopolyp.

Dig Endosc 2021 Apr 12. Epub 2021 Apr 12.

Department of Gastroenterology and Hepatology, University Hospitals Leuven, Belgium.

Digital single-operator cholangioscopy (DSOC) has revolutionized the endoscopic diagnosis and treatment of various hepato-pancreaticobiliary diseases, such as indeterminate biliary strictures and large balloon dilation-refractory common bile duct (CBD) stones, using either a retrograde or antegrade approach. Direct visualization provided by DSOC has furthermore paved the road towards minimally invasive treatment of intraductal neoplasms, although little evidence is available in this specific context. A 70-year-old patient was admitted following several episodes of colicky abdominal discomfort, mixed liver function abnormalities and non-intentional weight loss. Read More

Extrapelvic bowel resection and anastomosis in cytoreductive surgery for ovarian cancer.

Gland Surg 2021 Mar;10(3):1207-1211

Division of Gynecologic Oncology, Ajou University School of Medicine, Suwon, Korea.

Ovarian cancer is known as the second most common cause of death among gynecologic cancers. Survival outcome has been reported to be significantly associated with the efforts to minimize residual disease after cytoreductive surgery. As ovarian cancer often invades the small and large bowel without boundary, bowel surgery has been a crucial part of the cytoreductive surgery to achieve complete tumor removal. Read More

Osteoblastoma of the Distal Radius.

J Hand Surg Am 2021 Apr 8. Epub 2021 Apr 8.

Department of Pathology, Maulana Azad Medical College and Associated Lok Nayak Hospital, New Delhi, India.

Osteoblastomas are rare, benign, bone-forming neoplasms that represent less than 1% of all bone tumors and occur mostly in people aged 10 to 30 years. In long bones, the metadiaphyseal region tends to be most commonly affected. However, to the best of our knowledge, only 11 cases have been reported to occur in the distal radius. Read More
