Malignant Atrophic Papulosis

Background:
Kohlmeier-Degos (KD) is a rare disease that causes inflammation and blood clots, leading to blockages in small blood vessels. These blockages can result in K-D lesions throughout the body, affecting the skin, lungs, heart, spinal cord, and brain. KD can be fatal. No treatment exists for this disease.
Objective:
To test a study drug (baricitinib) in people with brain and spine lesions caused by KD disease. Baricitinib is FDA approved to treat other disorders but has not yet been tried in people with KD.
Eligibility:
People aged 18 years or older with KD-related lesions in the brain and spine.
Design:
Participants will be screened; they will have a physical exam with blood tests. They will also have a baseline visit that may include multiple tests, such as imaging scans of the brain and spine; a lumbar puncture to collect fluid from the spinal canal; and a meeting with a neurologist. They will fill out a questionnaire about their health. They will continue to take their normal medications throughout the study.
Baricitinib is a tablet taken by mouth. Participants will remain on their normal medications for 12 weeks after their baseline visit. Then they will also take the study drug once a day at home for 24 weeks.
Participants will have clinic visits every few weeks for up to 40 weeks. Some visits may take 1 to 4 days. Baseline tests will be repeated 3 more times during study visits. Other visits will require only blood tests; these may be done by local labs that will send the samples to NIH; 2 visits may be done via telehealth....

Background:
Kohlmeier-Degos (K-D) is a rare disease that leads to the blockage of small blood vessels in many organs; these can include the skin, eyes, stomach, lungs, heart, and the brain and spinal cord (central nervous system, or CNS). There are no known effective treatments for K-D that affects the CNS.
Objective:
To test a drug (ruxolitinib) in a person with K-D affecting the CNS.
Eligibility:
This study is designed to treat 1 subject, a 58-year-old male with K-D affecting the CNS.
Design:
The participant will be screened:
He will have a physical exam and blood tests.
He will have skin biopsies: Small samples of skin will be removed.
He will have a lumbar puncture: A needle will be inserted in his back to draw fluid from the space around the spinal cord.
He will have a magnetic resonance imaging (MRI) scan: He will lie on a table that slides into a tube to take pictures of his brain and spinal cord.
He will see a doctor who specializes in nerves.
Ruxolitinib is a tablet taken by mouth. The participant will take the drug twice a day for up to 26 weeks. The dosage may change over time.
The participant will have up to 7 clinic visits in 28 weeks. Each visit will be 1 to 3 days. MRI scans, biopsies, lumbar punctures, and other tests will be repeated on different visits. The participant may receive follow-up phone calls between visits. He will report any adverse effects. Unscheduled visits may be needed if new symptoms develop.
The last follow-up will be 4 weeks after the last dose of the study drug....

The purpose and main objective of this study is the research of pre-operative and operative predictive factors of short-term (1-year) and long-term (15-years) improvement of quality of life, motor and non-motor symptoms in Parkinson's disease patients who have undergone to bilateral Subthalamic Nucleus Deep Brain Stimulation.
The hypothesis of the study is that the definition of pre-operative and operative predictive factors could be able to improve the pre-operative prognostic accuracy of outcome and complications after surgery, allowing also a better selection of the most suitable candidates for bilateral Subthalamic Nucleus Deep Brain Stimulation.
For example, we can suppose that an older age at surgery, elevated axial score, a less preoperative dopa-responsiveness, the presence of mild executive dysfunction at surgery or an unfavourable social status, could negatively influence the short and long term surgery outcome
