Clinical Reasoning: A 22-Year-Old Man With Multifocal Brain and Osseous Lesions.

The evaluation of patients with disseminated processes with CNS and osseous involvement is often challenging. A 22-year-old healthy man developed left-sided weakness, paresthesias, and neck pain over several weeks. On clinical examination, he was noted to have decreased right eye visual acuity, left-sided pyramidal weakness and numbness, and bilateral hyperreflexia.

Predictors of prognosis of synchronous brain metastases in small-cell lung cancer patients.

Patients with small cell lung cancer (SCLC) are more likely to have synchronous brain metastasis (SBM) at the time of diagnosis than patients with any other extracranial primary malignancy. We sought to identify which factors predicted an increased risk of SBM in SCLC as well as which factors affected the prognosis of these patients. 38,956 Patients in the Surveillance, Epidemiology, and End Results (SEER) database with microscopically confirmed SCLC from 2010 to 2016 were identified.

Inchoate guidelines of endoscopic resection of colloid cysts.

Colloid cyst are cystic lesions in the third ventricle and could render patients asymptomatic. However, there is an inherent risk of symptomatic progression, acute decompensation, and sudden death. Therefore, there is no clear consensus as how to observe or when to treat a newly diagnosed patient with a colloid cyst.

Thirty-day readmission risk after intracranial tumor resection surgeries in children.

Objective: The risk of readmission after brain tumor resection among pediatric patients has not been defined. The authors' objective was to evaluate the readmission rates and predictors of readmission after pediatric brain tumor resection.

Methods: Nationwide Readmissions Database (NRD) data sets from 2010 to 2014 were searched for unplanned readmissions within 30 days of the discharge date after pediatric brain tumor resection.

Occipital neuralgia: A neurosurgical perspective.

Occipital neuralgia typically arises in the setting of nerve compression by fibrosis, surrounding anatomic structures, or osseous pathology, such as bone spurs or hypertrophic atlanto-epistropic ligament. It generally presents as paroxysmal bouts of sharp pain in the sensory distribution of the first three occipital nerves. Due to the long course of the greater occipital nerve (GON), and its peculiar anatomy, and location in a mobile region of the neck, it is unsurprising that the GON is at high risk for compression.

Intracranial anaplastic hemangiopericytoma presenting with simultaneous extra-cranial metastases: A case report and review of the literature.

Background: Intracranial solitary fibrous tumor/hemangiopericytoma (SFT/HPC) is a rare mesenchymal tumor with a propensity to recur and metastasize extracranially years after treatment. Accordingly, there are no reported cases of a patient presenting with a simultaneous intracranial primary and extracranial metastases. We present the case of a patient presenting with an intracranial SFT/HPC and simultaneous liver metastases and propose a treatment paradigm.

Neurologic injuries following road traffic accidents in the Dominican Republic: Examining causes and potential solutions.

Road traffic accidents (RTAs) are the number one cause of traumatic brain injuries (TBIs) worldwide. This study examines RTA-related TBIs in the Dominican Republic, a country in the Caribbean with the highest RTA fatality rate in the Western Hemisphere. We interviewed 117 adult patients or medical guardians of patients admitted to Hospital Traumatológico Dr.

Concomitant ruptured anterior circulation and unruptured posterior circulation aneurysms: Treatment strategy and review of literature.

Basilar artery apex or bifurcation is the most common location for aneurysms arising from posterior cerebral circulation. Reports of unruptured aneurysms of the basilar bifurcation associated with ruptured anterior circulation aneurysms are rare. The presence of multiple intracranial aneurysms poses a significantly high risk to management than a single aneurysm due several factors involved.

Predictors of 90-Day Readmission in Children Undergoing Spinal Cord Tumor Surgery: A Nationwide Readmissions Database Analysis.

Objective: A fair number of hospital admissions occur after 30 days; thus, the true readmission rate could have been underestimated. Therefore, we hypothesized that the 90-day readmission rate might better characterize the factors contributing to readmission for pediatric patients undergoing spinal tumor resection.

Methods: The Nationwide Readmissions Database was used to study the patient demographic data, comorbidities, admissions, hospital course, spinal tumor behavior (malignant vs.

Membranous staining of β-catenin and E-cadherin expression in patients with gastric cancer.

Background: β-catenin and E-cadherin are adhesion molecules that promote metastatic potential through epithelial-mesenchymal transition (EMT). Although they have not been extensively studied in gastric cancers, they represent potential testable prognostic markers.

Methods: We explored the association between the immunohistochemical expression of these markers and clinicopathologic parameters by retrospectively reviewing 205 cases of gastric cancer from tissue microarrays (TMA).

Repeat gas insufflation for successful closure of idiopathic macular hole following failed primary surgery.

A 65-year-old lady presented with decreased vision in left eye since seven months. Vision was 6/9 in right eye and 6/36 in left. Examination revealed idiopathic, full-thickness macular hole in left eye; confirmed by optical coherence tomography (OCT).

Delayed, spontaneous conversion of type 2 closure to type 1 closure following surgery for traumatic macular hole associated with submacular hemorrhage.

A 45-year-old man presented with diminution of vision in the left eye following a firecracker injury. Best corrected visual acuity (BCVA) was 20/20 in the right eye and 20/125 in the left eye. Fundus examination revealed vitreous hemorrhage, a macular hole, and submacular hemorrhage in the left eye.

Prevalence of myopia and its association with diabetic retinopathy in subjects with type II diabetes mellitus: A population-based study.

Objective: To report the prevalence of myopia and its association with diabetic retinopathy in subjects with type II diabetes mellitus and compare the diabetic retinopathy status in the myopic group vs the emmetropic group.

Design: Population-based study.

Materials And Methods: The population-based study estimated the prevalence of myopia from 1058 subjects, who were more than 40 years old and had type II diabetes mellitus; the patients were enrolled from a cross-sectional study.

Subperiostial recurrence of chondroblastoma.

We present a case of subperiosteal recurrence of chondroblastoma adjacent to the greater trochanter that was initially thought to represent septic arthritis of the hip in a 10-year-old girl. Soft-tissue recurrence of chondroblastoma is very rare, with fewer than ten cases reported in the literature. We demonstrate the recurrence on both CT and MRI.
