  Blepharospasm (BSP) is a type of focal dystonia characterized by spasms of the eyelids, involuntary closure of the eye, increased spontaneous blinking, or any combination of the previous ones. Patients may initially experience mild and infrequent spasms. However, as symptoms progress, patients may experience visual disability and social withdrawal within 6 months to 3 years, significantly impacting their quality of life. Blepharospasm is characterized by orbicularis oculi muscle spasms that are stereotyped, bilateral, and synchronous. Spasms can be brief or prolonged, and they can cause the eyelids to narrow or close. Sensory tricks that can temporarily improve eyelid spasms in about half of the patients, associated apraxia of eyelid opening, and increased spontaneous blink rate are also relevant manifestations. Dystonia is a functional disorder, so neurophysiology is an essential methodology for studying it, identifying the underlying pathophysiological mechanisms, and providing...

  Attention-deficit/hyperactivity disorder (ADHD) is a brain disorder marked by an ongoing pattern of inattention and hyperactivity-impulsivity that interferes with functioning or development. ADHD is a group of behaviors. It is also called attention deficit disorder (ADD). Attention deficit hyperactivity disorder (ADHD) is a behavioral disorder that includes inattentiveness, hyperactivity, and impulsiveness symptoms. ADHD symptoms are generally noticed at a young age and may become more noticeable as a child's circumstances vary, such as when they start school. The majority of cases are found when children are between six and twelve. ADHD symptoms generally improve with age, but many adults diagnosed with the condition at a young age continue to struggle. People who have ADHD may also suffer from sleep and anxiety disorders. Individuals with ADHD may also work with attention, executive function, and working memory. Executive function deficits have recently emerged as critical fact...

  Allergic conjunctivitis is one of the most ordinary forms of conjunctivitis. Allergic conjunctivitis causes red, watery, itchy, or gritty eyes. It usually happens when a person's eyes contact with an allergen, a substance that makes the body's immune system overreacting. Symptoms arise due to the body's overreacting immune system, which causes histamine and other active substances to be released through mast cells. The vision becomes sore and inflamed. The nerve endings are irritated when blood vessels dilate or expand. As a result, tears are secreted more frequently. Typically, the condition is not painful and does not cause light sensitivity in the eyes. Allergic conjunctivitis is caused by an allergen-induced inflammatory response in which allergens interact with IgE bound to sensitized mast cells, resulting in clinical allergic manifestations of the eyes. AC is the only ocular disease caused entirely by a type I allergic reaction. In sensitized individuals, T2 cells r...

  Mantle cell lymphoma (MCL) is caused by the malignant transformation of a B lymphocyte on the rim of a lymph node follicle (the mantle zone). The transformed B lymphocyte grows uncontrollably, resulting in the accumulation of lymphoma cells, which causes the enlargement of lymph nodes. MCL cells can enter lymphatic channels and the blood, spreading to other lymph nodes or tissues like the bone marrow, liver, and gastrointestinal tract. In almost all cases, MCL is distinguished by the overexpression of cyclin D1 (a protein that promotes cell growth). Cyclin D1 overexpression is typically caused by a rearrangement (translocation) between chromosomes 11 and 14. Mantle cell lymphoma is associated with a relapsing and remitting course with the current treatment strategies, with a generally shorter duration of remission with each subsequent line of therapy. Recent drug approvals have improved outcomes for patients with relapsed MCL; in the United States, 5,970 new cases of MCL are bein...

  Oral Mucositis (OM), also called stomatitis, is the most common, debilitating complication of cancer chemotherapy and radiotherapy, characterized by inflammation and ulceration in the oral cavity caused by the chemotherapeutic drug substances and radiotherapy used in cancer treatment. Typical manifestations of Oral Mucositis are varying degrees of erythema, atrophy, ulceration, and mucosa swelling. It has a significant negative impact on patients’ quality of life (QOL). Potential complications of OM include pain, increased the risk of local and systemic infections, bleeding, insufficient food intake, delays in the administration of radiotherapy and or chemotherapy, a dose reduction of the chemotherapy drugs, increased the length of hospital stays, associated economic burdens and in some cases life-threatening infections (septicemia in neutropenic instances). Mucositis is one of the most generally reported toxicities of mTOR inhibitors, and in some studies, it was the dose-limitin...

  Familial adenomatous polyposis (FAP) is an inherited condition that primarily affects the gastrointestinal tract. This condition causes hundreds or thousands of polyps to form inside the colon and rectum. This condition is also known as hereditary polyposis of the colorectum, Gardner's syndrome, and familial polyposis. Nearly 100% progression to colorectal cancer (CRC) by the age of 35–40 yr and a heightened risk of various other malignancies. Familial adenomatous polyposis (FAP) is a highly penetrant autosomal-dominant disorder caused by a germline mutation in the adenomatous polyposis coli (APC) gene chromosome 5q21. Over 700 different disease-causing APC mutations have been reported to date. However, the most common germline mutation involves the introduction of a premature stop codon, either by a nonsense mutation (30%), frameshift mutation (68%), or large deletion (2%), leading to truncation of the protein product in the C-terminal region.   The birth frequency of F...

  Endometriosis is defined as the abnormal growth of endometrial tissue, which is similar to that which lines the interior of the uterus but occurs outside of the uterus. During menstruation, endometrial tissue is shed. Endometrial implants are areas of endometrial tissue found in ectopic sites. These lesions are most generally found on the ovaries, the Fallopian Tubes, the uterine surface, the bowel, and the pelvic cavity membrane lining (i.e., the peritoneum). They are less frequently found in the vaginal, cervix, and bladder. Endometriosis can occur outside the pelvis on rare occasions. While endometrial implants can cause complications, they are usually harmless. Endometriosis is classified into four stages: I (mild), II (mild), III (moderate), and IV (severe) based on the number, location, and depth of implants, as well as the presence of filmy or dense adhesions. Another staging system is based primarily on the company and severity of pelvic pain. However, a more reliable sta...
