Giant pituitary adenomas (diameter >4 cm) are a challenge to treat, and there is no consensus on the optimal surgical strategy. We report here our experience in surgical management of these lesions. Adult patients with giant pituitary adenomas (n = 62; 54 non-functioning and eight hormone-secreting adenomas) who underwent surgical resection at our hospital from 2009 to 2015 were retrospectively reviewed. Surgical and clinical outcomes were analyzed. Single transsphenoidal and transcranial approaches were used in 43 (69...

BACKGROUND Leptospirosis is a zoonosis transmitted through urine of infected animals. Symptoms range from mild influenza-like symptoms to severe pulmonary hemorrhagic syndrome (SPHS); the latter are often fatal. The serogroup distribution in Denmark has changed from 1988 to 2012, with Icterohaemorrhagiae and Sejroe now being predominant. CASE REPORT A 45-year-old Danish woman living in an area endemic for Hanta virus, without prior medical history, was admitted because of lower back pain radiating to the left hip, fever, headache, nausea, and malaise...

Delayed intracranial hemorrhage is a rare complication of treatment for central nervous system tumors. This may be secondary to malignant transformation of the tumor or vasculopathy related to radiation therapy (RT). While most reports on radiation-induced vasculopathy in children with optic pathway gliomas are associated with ischemic complications, there are only two reports of hemorrhagic complications in these patients. In both cases, the hemorrhage was asymptomatic and remote from the site of the original tumor but within the field of irradiation...

Patients who have had a stroke are at high risk for recurrent stroke, myocardial infarction, and vascular death. Prevention of these events should be initiated promptly after stroke, because many recurrent events occur early, and should be tailored to the precise cause of stroke, which may require specific treatment. Lifestyle advice including abstinence from smoking, regular exercise, Mediterranean-style diet, and reduction of salt intake and alcohol consumption are recommended for all patients with stroke...

Atypical teratoid/rhabdoid tumor (AT/RT) is a highly malignant embryonal central nervous system tumor commonly affecting children <3 years of age. It roughly constitutes 1%-2% of all pediatric central nervous system tumors. Recent data show that it is the most common malignant central nervous system tumor in children <6 months of age. Management of this aggressive tumor is associated with a myriad of diagnostic and therapeutic challenges. On the basis of radiology and histopathology alone, distinction of AT/RT from medulloblastoma or primitive neuroectodermal tumor is difficult, and hence this tumor has been commonly misdiagnosed as primitive neuroectodermal tumor for decades...

OBJECTIVE: To describe the management of grade 4 Radiation Therapy Oncology Group (RTOG) urinary adverse events (UAEs) after radiotherapy (RT) for prostate cancer (PCa). We hypothesized grade 4 UAEs often require complex surgical management and subject patients to significant morbidity. METHODS: A single-center retrospective review, over a 6-year period (2010-2015), identified men with RTOG grade 4 UAEs after RT for PCa. RT was classified as combined modality therapy (radical prostatectomy (RP) followed by external beam radiotherapy (EBRT), EBRT + low-dose brachytherapy (LDR), EBRT + high-dose brachytherapy (HDR), or other combinations of RT) or single modality RT...

Results from our recent studies have led to the novel hypothesis that radiation-induced coagulopathy (RIC) and associated hemorrhage occurring as part of the acute radiation syndrome (ARS) is a major cause of death resulting from radiation exposure in large mammals, including humans. This article contains information related to RIC, as well as potential strategies for the prevention and treatment of RIC. In addition, new findings are reported here on the occurrence of RIC biomarkers in humans exposed to radiation...
