Klebsiella pneumoniae brain abscesses in an elderly patient without clinically evident neurological signs and symptoms.

CONCLUSION: Cranial MRI should be performed to identify the presence of brain abscesses in elderly patients with K. pneumoniae bloodstream infections but without clinically evident neurological signs or symptoms. Serial MRI studies are important to monitor the therapeutic course. PMID: 31321760 [PubMed - in process]

Authors: Kanclerz P, Grzybowski A Abstract Silicone oil (SO) is used mainly when managing complex retinal detachments, commonly with proliferative vitreoretinopathy, as well as a hemostatic agent in proliferative diabetic retinopathy. Combined lens exchange and pars plana vitrectomy remains preferred by many surgeons; however, sequential surgery might be advantageous to minimize the postoperative anterior chamber inflammatory response, particularly in proliferative diabetic retinopathy or retinal detachment. The aim of the study was to evaluate the optimal method of intraocular lens (IOL) calculation in eyes filled...

A 77-year-old man with a history of hypertension, type 2-diabetes and chronic obstructive pulmonary disease came to the Emergency Department of our hospital with visual impairment, agraphia and memory loss. Cranial computed tomography (CT) revealed a hypodense lesion in the left posterior parietal white matter (maximum diameter of 4.5  cm) with vasogenic oedema. He was admitted to hospital to complete study of the primary neoplasm for suspicion of brain metastases. On day 3 post-admission, brain magnetic resonance imaging showed three images that suggested brain metastases.

We report a 70-year-old man with diabetes who presented to our outpatient clinic with severe chronic daily complaints of headache. The headache was located frontoparietally and kept him awake at night. Imaging (nonenhanced computed tomography [CT], magnetic resonance imaging, and positron emission tomography/CT) showed a hypermetabolic mass on the right side of the skull base, in the middle ear, and in the mastoid process, with invasion and partial destruction of the surrounding elements of the petrous bone, the occipital bone, and the sphenoid bone on the right, with extension by way of the clivus into the apex of the lef...

We report a patient on maintenance hemodialysis from standalone unit presented to us with abnormal neurological signs and symptoms. His medication chart included metformin, which he was taking for quite a long time. Computed tomography brain showed hypointensity in bilateral basal ganglia. Magnetic resonance imaging (MRI) brain showed hyperintensity in T2/fluid-attenuated inversion recovery sequences suggestive of Lentiform fork sign. We stopped metformin, and he was continued on regular hemodialysis. He showed dramatic improvement in neurological manifestations. Two months later, we repeated MRI brain, which showed resolu...

Conclusions: The diagnosis of adrenocortical oncocytoma mainly depends on the pathological examination. Surgical resection is the main treatment method. Introduction The oncocytic adrenocortical neoplasm is a rare tumor of the adrenal gland. Since it was first reported in 1986 (1), there has been serial case reports to try to illuminate this rare tumor. However, there is still rather little information available, especially the pathological and follow-up data, to illustrate the biological behavior of this particular tumor. The origin, biological behavior, diagnostic criteria, and prognosis of oncocytic adrenocortic...

We present a 70-year-old woman with severe diabetes mellitus, who experienced low back pain and left lower leg paralysis. Computed tomography showed air in the spinal canal from C4 to S5, and magnetic resonance imaging revealed an epidural abscess from Th11 to L1. Laboratory findings showed increases in inflammatory indicators and blood culture indicated the presence of Escherichia coli. The patient was treated conservatively with antibiotics. Neurological deficits and inflammatory data improved during the course. Follow-up imaging studies showed the disappearance of gas and epidural abscess. The existence of air in the sp...

Conclusion: Intracranial artery calcification is common in patients with ischemic cerebrovascular disease and the intracranial carotid artery is most frequently affected. Intracranial arterial calcifications might be associated with imaging markers of SVD and are highly correlated with WMHs, lacunes, and CMBs. Quantification of calcification on CT provides additional information on the pathophysiology of SVD. Intracranial arterial calcification could act as a potential marker of SVD. Introduction Atherosclerosis is a systemic vascular process that is considered a major cause of cerebrovascular and cardiovascular di...

Conclusion Taken together, evidence from animal and human studies demonstrates that the brain detects levels of circulating nutrients and hormones and consequently organizes an outward response that contributes to the regulation of whole-body glucose homeostasis. However, there are major knowledge gaps about the exact nature of this response and its relative importance compared to peripheral processes. As we have seen, animal studies have provided an anatomical map of CNS glucose regulation and have identified important neurons and neural circuits involved. Additionally, the CNS sensing of key nutrients and hormones has b...
