Reversible corpus callosum splenial (CCS) lesions have been described in patients with varied etiologies. The most common causes of previously reported reversible focal lesions of the CCS are viral encephalitis, antiepileptic drug toxicity/withdrawal, and metabolic disorders. Intravenous immunoglobulin (IVIG) therapy is used for different immune-mediated diseases. It is generally safe, and serious adverse reactions are uncommon. We presented a rare case of disturbed consciousness with reversible CCS lesions after IVIG therapy for Guillain-Barre syndrome in an adult woman...

Sumner L Norman, Joan Lobo-Prat, David J Reinkensmeyer
Robotic devices can train strength, coordination, or a combination of both. If a robotic device focuses on coordination, what happens to strength recovery, and vice versa? Understanding this interaction could help optimize robotic training. We developed a computational neurorehabilitation model to gain insight into the interaction between strength and coordination recovery after stroke. In the model, the motor system recovers by optimizing the activity of residual corticospinal cells (focally connected, excitatory and inhibitory) and reticulospinal cells (diffusely connected and excitatory) to achieve a motor task...

Intravenous immunoglobulin (IVIG) is a commonly used and generally well-tolerated medication. Common side effects include flu-like symptoms such as fevers, headaches, myalgia, fatigue, and nausea. One of the more rare side effects is aseptic meningitis, with a reported incidence rate of around 0.067 percent of all IVIG infusions. In this paper, we describe a 47-year-old female patient with a history of myasthenia gravis who presented with a headache, neck pain, and neck stiffness while undergoing IVIG infusions for a myasthenia crisis...

Angiogenesis as a pathological process in the eye can lead to blindness. In the cornea, suppression of angiogenesis by anti-VEGF treatment is only partially effective while steroids, although effective in treating inflammation and angiogenesis, have broad activity leading to undesirable side effects. In this study, genome-wide expression was investigated in a suture-induced corneal neovascularization model in rats, to investigate factors differentially targeted by dexamethasone and anti-Vegf. Topical treatment with either rat-specific anti-Vegf, dexamethasone, or normal goat IgG (sham) was given to sutured corneas for 48 hours, after which in vivo imaging, tissue processing for RNA microarray, and immunofluorescence were performed...

BACKGROUND: Leishmaniasis is a common parasitic disease seen in many parts of the world, especially in areas where current U.S. and international forces are deployed. Approximately 350 million people are thought to be at risk of cutaneous leishmaniasis (CL) with an annual incidence of 1.5 million cases. Over 90% of cutaneous infections with Leishmania occur in the Middle East, Brazil, and Peru. Outbreaks of CL may occur in military personnel deployed to endemic areas. Since the incubation period for symptomatic CL ranges from weeks to months, symptoms may not appear until well after returning to the United States...

Boiling histotripsy is a method of focused ultrasound surgery that noninvasively applies millisecond-length pulses with high-amplitude shock fronts to generate liquefied lesions in tissue. Such a technique requires unique outputs compared to a focused ultrasound thermal therapy apparatus, particularly to achieve high in situ pressure levels through intervening tissue. This article describes the design and characterization of a system capable of producing the necessary pressure to transcutaneously administer boiling histotripsy therapy through clinically relevant overlying tissue paths using pulses with duration up to 10 ms...

Tourette syndrome (TS) is a common neuropsychiatric disorder, more common in males than females, with onset before age 18. TS is characterized by multiple motor tics and one or more vocal/phonic tics, persisting for more than a year. Tics are unvoluntary, abrupt, rapid, repetitive, but non-rhythmic movements or sounds (vocalizations). They are preceded by an inner urge. Tics can be temporarily suppressed, but this leads to a powerful re-emergence. The performance of tics results in immediate but transient relief...

Primary sclerosing cholangitis (PSC) is a rare disorder characterized by multi-focal bile duct strictures and progressive liver disease. Inflammatory bowel disease (IBD) is usually present and there is a high risk of cholangiocarcinoma and colorectal cancer. With no effective medical therapy, most patients ultimately require liver transplantation, after which disease recurrence may occur. With limited therapeutic options and lack of proven surveillance strategies, patients experience significant unmet needs...

Malignant epidural spinal cord compression (MESCC) is an oncologic emergency with the potential for devastating consequences for patients if not promptly diagnosed and treated. MESCC is diagnosed by imaging. MRI is by far the most sensitive test, preferably with gadolinium. Once the diagnosis of MESCC is suspected, patients with neurologic deficits should receive prompt administration of dexamethasone with a 10-mg IV loading dose followed by 4 mg every 6 h. Quick taper is recommended once the definitive treatment is established...

BACKGROUND: High intensity focused ultrasound (HIFU) has gained clinical interest as a non-invasive local tumour therapy in many organs. In addition, it has been shown that lung cancer can be targeted by HIFU using One-Lung Flooding (OLF). OLF generates a gas free saline-lung compound in one lung wing and therefore acoustic access to central lung tumours. It can be assumed that lung parenchyma is exposed to ultrasound intensities in the pre-focal path and in cases of misguiding. If so, cavitation might be induced in the saline fraction of flooded lung and cause tissue damage...

In light of the rapid increase in the number of obesity incidences worldwide, obesity has become an independent risk factor for chronic kidney disease. Obesity-related glomerulopathy (ORG) is characterized by glomerulomegaly in the presence or absence of focal and segmental glomerulosclerosis lesions. IgM and complement 3 (C3) nonspecifically deposit in lesions without immune-complex-type deposits during ORG immunofluorescence. ORG-associated glomerulomegaly and focal and segmental glomerulosclerosis can superimpose on other renal pathologies...
