The present study was conducted to determine the correlation between high perfusion syndrome and stent restenosis after cerebral vascular stent implantation. A total of 146 patients diagnosed with cerebral vascular stenosis and stent implantation were selected. A total of 55 cases (37.67%) of cerebral hyperperfusion syndrome patients were diagnosed by xenon-enhanced computer tomography (Xe-CT) examination and clinical symptoms within 3 days after surgery and were chosen as the observation group. A total of 91 cases were selected as the control group...

Bacillary angiomatosis is an infection determined by Bartonella henselae and B. quintana, rare and prevalent in patients with acquired immunodeficiency syndrome. We describe a case of a patient with AIDS and TCD4+ cells equal to 9/mm3, showing reddish-violet papular and nodular lesions, disseminated over the skin, most on the back of the right hand and third finger, with osteolysis of the distal phalanx observed by radiography. The findings of vascular proliferation with presence of bacilli, on the histopathological examination of the skin and bone lesions, led to the diagnosis of bacillary angiomatosis...

Accurate characterization of cirrhotic nodules and early diagnosis of hepatocellular carcinoma (HCC) are of vital importance. Currently, computed tomography (CT) and magnetic resonance (MR) imaging are standard modalities for the investigation of new nodules found at surveillance ultrasonography (US). This article describes the successful integration of contrast material-enhanced US into a multimodality approach for diagnosis of HCC and its benefits in this population. The application of contrast-enhanced US immediately following surveillance US allows for prompt dynamic contrast-enhanced evaluation, removing the need for further imaging of benign lesions...

Kaposi's sarcoma (KS) typically presents multiple cutaneous lesions of the lower extremities. Lesions can rarely mimic varicose veins without venous insufficiency, vascular or stasis ulcers. As the initial diagnosis of KS is generally determined clinically, a high index of suspicion and palpation of lesions are necessary for all patients with atypical presentations of varicose-like lesions of lower extremities. Tissue biopsy with histological analysis is essential for all uncertain lesions. This is a case of KS occurring in a 79-year-old man who presented with indurated vascular plaques resembling varicose veins on the right foot...

Most breast cancer-related deaths from triple-negative breast cancer (TNBC) occur following metastasis of cancer cells and development of tumors at secondary sites. Because TNBCs lack the three receptors targeted by current chemotherapeutic regimens, they are typically treated with extremely aggressive and highly toxic non-targeted treatment strategies. Women with TNBC frequently develop metastatic lesions originating from drug-resistant residual cells and have poor prognosis. For this reason, novel therapeutic strategies that are safer and more effective are sought...

Lymph vessels play a crucial role for immune reactions in health and disease. In oncology the inhibition of lymphangiogenesis is an established therapeutic concept to reduce metastatic spreading of tumor cells. During allogeneic tissue transplantation the inhibition of lymphangiogenesis has been successfully used to attenuate graft rejection. Despite its critical importance for tumor growth, allo-immune responses and inflammation, the role of lymphangiogenesis has not been investigated during allogeneic hematopoietic stem cell transplantation (allo-HSCT)...

Post-stroke dementia (PSD) or post-stroke cognitive impairment (PSCI) may affect up to one third of stroke survivors. Various definitions of PSCI and PSD have been described. We propose PSD as a label for any dementia following stroke in temporal relation. Various tools are available to screen and assess cognition, with few PSD-specific instruments. Choice will depend on purpose of assessment, with differing instruments needed for brief screening (e.g., Montreal Cognitive Assessment) or diagnostic formulation (e...

We report a case of optic disc granuloma due to sarcoidosis. A 64-year-old, caucasian female with a history of pulmonary sarcoidosis presented with a vision loss on her left eye. The ophthalmologic examination revealed a discrete optic disc infiltrate compatible with the diagnosis of optic disc granuloma. Fluorescein angiography showed diffusion and impregnation of the granuloma without vascularitis. The optical coherence tomography demonstrated a homogenous and isoreflective lesion at the optic disc. The patient recovered her visual acuity after systemic corticosteroid treatment...

Neuropathic symptoms after median nerve repair at the wrist or secondary to refractory carpal tunnel syndrome may become debilitating. These symptoms develop due to perineural adhesions, intraneural fibrosis and fixation of the nerve to the transverse carpal ligament after surgery and often require neurolysis. Interposition of vascularized soft tissue over the median nerve at the time of neurolysis prevents recurrence of such adhesions. The synovial flap, fashioned from the synovial lining of the flexor tendon sheath, is an ideal tissue for this purpose...

Laser treatment is the most effective therapy in dermatology for vascular skin disorders, such as port-wine stains (PWS). Changes in heat-induced absorbance in blood must be determined for accurate numerical simulation and implementation of multi-pulse laser therapy for treatment of PWS. Thermally induced absorbance changes in hemoglobin in blood were compared in vitro between slow water bath heating and fast heating irradiated by using sub-millisecond Nd:YAG laser. Blood composition at different temperatures was calculated by comparing blood absorption spectra with those of pure HbO2, Hb, and metHb at room temperature...

It is well-documented in literature that benign breast lesions, such as fibroadenomas, are loosely bonded to their surrounding tissue and tend to slip under a small quasi-static compression, whereas malignant lesions being firmly bonded to their surrounding tissue do not slip. Recent developments in quasi-static ultrasound elastography have shown that an image of the axial-shear strain distribution can provide information about the bonding condition at the lesion-surrounding tissue boundary. Further studies analyzing the axial-shear strain elastograms revealed that nonzero axial-shear strain values appear inside the lesion, referred to as fill-in, only when a lesion is loosely bonded and asymmetrically oriented to the axis of compression...

Clinical studies have revealed a strong link between increased burden of cerebral microinfarcts and risk for cognitive impairment. Since the sum of tissue damage incurred by microinfarcts is a miniscule percentage of total brain volume, we hypothesized that microinfarcts disrupt brain function beyond the injury site visible to histological or radiological examination. We tested this idea using a mouse model of microinfarcts, where single penetrating vessels that supply mouse cortex were occluded by targeted photothrombosis...

Dieulafoy lesions, vascular anomalies typically found along the gastrointestinal tract, have been viewed as rare and obscure causes of sudden intestinal bleeding, especially in pediatric patients. Since their discovery in the late 19th century, the reported incidence has increased. This is due to an increased awareness of, and knowledge about, their presentation and to advanced endoscopic diagnosis and therapy. Our patient was a three-year-old male, without a complex medical history. He presented to the emergency department with acute hematemesis with blood clots and acute anemia requiring blood transfusion...

OBJECTIVES: We evaluated the clinical outcomes of patients with chronic kidney disease (CKD) who underwent orbital atherectomy for severe coronary artery calcification (CAC) prior to stent implantation. BACKGROUND: Percutaneous coronary intervention (PCI) of lesions with severe CAC is associated with increased rates of adverse clinical events. Patients with CKD are at increased risk for atherosclerotic cardiovascular disease, including vascular calcification, and have worse outcomes after PCI...

BACKGROUND: Skull base cerebrospinal fluid (CSF) leak after gamma knife radiosurgery (GKRS) is a very rare complication. In patients who were treated with both GKRS and transsphenoidal resection (TSR) for pituitary lesions, early CSF leak occurs at a comparable rate to the general TSR population (4%). Delayed CSF leak occurring more than a year after TSR, GKRS, or dual therapy, is exceedingly rare. METHODS: Retrospective chart review and review of the literature RESULTS: We present two cases of delayed CSF leak following GKRS to treat pituitary adenoma...
