Vatche, Minassian, MD, MPH, Chief of Urogynecology, and Sarah Cohen, MD, MPH, Director of the Minimally Invasive Gynecologic Surgery Fellowship Program at Brigham and Women’s Hospital, perform a laparoscopic burch colposuspension, a procedure used to correct stress urinary incontinence.
Stress urinary incontinence is one of the most common types of incontinence and is characterized by urinary leakage during physical activities including coughing, sneezing, exercising, lifting, and laughing. As the condition progresses, it can become severe enough to happen with simple acts such as bending and walking. This condition is due to an anatomic weakness of the bladder neck which typically maintains the seal of urine during activity. Stress incontinence can result from a variety of conditions including vaginal childbirth, aging, menopause and obesity. As this is an anatomic condition, primary treatment may involve pelvic floor exercises and/or minimally invasive surgery.

In PRK the epithelium (top layer of the cornea) is scraped off and then the laser treatment is applied. A contact lens is used as a "bandage" to decrease discomfort. The epithelium then grows back over the bare area during the next few days.
In LASEK the epithelium is exposed to 20% alcohol which helps separate epithelium from the cornea. The epithelium is pushed to one side and laser treatment applied. The epithelial layer is replaced back onto the eye and held in place with a contact lens. The contact lens is then removed a few days later. LASEK is hence a "no knife"/flap operation.
Epi-Lasik is a similar procedure that uses a keratome like that used for Lasik, but engineered to only separate the epithelium. The epithelium is left on a hinge, laser treatment applied and flap replaced.
Surgery is done to relieve pressure on the nerve roots. This can help reduce pain, numbness, and weakness in your legs. Surgery may be recommended if: Your pain, numbness, or weakness is so bad that it gets in the way of normal daily activities and hurts your quality of life. You are in otherwise good health. The goal of surgery is to relieve pain, numbness, or weakness in the legs-not to relieve back pain. People who have surgery only for back pain are less satisfied with the results than are those who have surgery for nerve root symptoms and pain in both the back and legs. Also, numbness, weakness, and pain may return after surgery.
Descemet’s stripping automated endothelial keratoplasty (DSAEK) avoids a full-thickness corneal procedure and provides rapid visual rehabilitation. Successful graft positioning while minimizing intraoperative donor endothelial trauma may determine long-term graft survival. Previously described t...echniques for graft insertion may be problematic in some patients with intraoperative floppy iris syndrome (IFIS), anatomically shallow or unstable anterior chambers, or intraoperative increased posterior pressure. This video displays alternative method called the suture drag technique, which may facilitate lamellar endothelial graft insertion under these special circumstances.
49-years old patient complaining of cough, fever and pleuritic pain for 2 weeks. At admission he was febrile and tachypnic. Chest X-Ray showed left pleural effusion. Thoracocentesis revealed purulent fluid. Chest CT-scan showed large and loculated left pleural effusion and pleural thickening. VATS decortication was performed through three incisions.
Interstitial cystitis is a clinical syndrome characterized by daytime and nighttime urinary frequency, urgency, and pelvic pain of unknown etiology. Interstitial cystitis has no clear etiology or pathophysiology, and diagnostic criteria for the syndrome remain undefined. Despite considerable research, universally effective treatments do not exist; therapy usually consists of various supportive, behavioral, and pharmacologic measures. Surgical intervention is rarely indicated. The International Continence Society has coined the term painful bladder syndrome (suprapubic pain with bladder filling associated with increased daytime and nighttime frequency, in the absence of proven urinary infection or other obvious pathology) and reserves the diagnosis of interstitial cystitis for patients with characteristic cystoscopic and histologic features of the condition.[1] An international consensus panel was able to generally agree on the following definition of interstitial cystitis/bladder pain syndrome (IC/BPS): unpleasant sensation (pain, pressure, discomfort) perceived to be related to the urinary bladder and associated with lower urinary tract symptoms of more than 6 weeks duration, in the absence of infection or other identifiable causes. American Urological Association (AUA) guidelines published in 2011 and amended in 2014 use an evidence-based approach to provide a clinical framework for the diagnosis and management of this condition.[2, 3, 4] In 1887, Skene initially described a condition characterized by inflammation that destroyed the urinary bladder "mucous membrane partly or wholly and extended to the muscular parietes." Guy Hunner popularized the disease with the description of characteristic bladder wall ulcers in association with a symptom complex of chronic bladder inflammation.[5] The first comprehensive epidemiologic description of interstitial cystitis is credited to Hand, who in 1949 described the widespread, small, submucosal bladder hemorrhages and the significant variation in bladder capacity characteristic of the condition. Despite years of intensive research, there are no specific clinical or urinary markers currently clinically available; no absolutely specific radiographic, laboratory, or serologic findings; and no biopsy patterns that are pathognomonic for interstitial cystitis. Some research suggests that the following may all play a role in the disease pathophysiology: (1) pelvic floor dyfunction, (2) dysregulated immune or inflammatory signals, (3) neural hypersensitivity, and (4) disruption of the proteoglycan/glycosaminoglycan (GAG) layer.[6] Interstitial cystitis, howerver, remains a diagnosis of exclusion (see Presentation, DDx, and Workup.) Intensive study has been done to attempt to identify biomarkers for IC/BPS. Some interesting studies have shown that bladder nitric oxide is an accurate marker for Hunner lesions, but these are not present in all patients, and the test requires specific equipment, which has limited widespread clinical use.[7] Differences in levels of cytokines and chemokines, specifically CXCL-10, have shown some ability to differentiate patients with and without Hunner lesions.[8] Other studies of ulcerative IC/BPS have shown that numerous other cytokines and chemokines are up-regulated as well, heralding a possible urinary test to identify patients.[9] An additional substance shown to be up-regulated in IC/BPS patients is antiproliferative factor (APF). This small 8–amino-acid peptide has been associated with suppression of cell growth, increases in transcellular permeability, and lowering of levels of proteins that form intercellular junctional complexes. It is synthesized and secreted from bladder epithelial cells from patients with IC/BPS and may play a key role in pathophysiology.[10] In vitro studies have shown that removal of APF from cell culture media restored cell proliferation and membrane integrity.[11] Studies have also suggested APF in the therapeutic effect of hydrodistension in patients with IC/BPS, although further confirmatory studies are necessary.[12] The most important element in treating patients with interstitial cystitis is education and emotional support. Periodic exacerbations are managed as they occur because no long-term therapy has been shown to prevent or delay recurrent episodes. Therefore, the purpose of treatment is to palliate and alleviate symptoms. Because no discrete pathognomonic pathologic criteria exist for assessing and monitoring disease severity, indications and goals for treatment are based on the degree of patient symptoms. Assessing patient response to treatment is also complicated because of the subjective nature of symptoms; the waxing and waning nature of symptoms without treatment; and the lack of objective serologic, physical, or histopathologic findings. Conservative measures and oral or intravesical treatments are considered first-line treatment. (See Treatment.)
Focal seizures (also called partial seizures [citation needed] and localized seizures) are seizures which affect initially only one hemisphere of the brain. [citation needed] The brain is divided into two hemispheres, each consisting of four lobes – the frontal, temporal, parietal and occipital lobes.
Factitious disorder is the term used to describe a pattern of behavior centered on the exaggeration or outright falsifications of one’s own health problems or the health problems of others. Some people with this disorder fake or exaggerate physical problems; others fake or exaggerate psychological problems or a combination of physical and psychological problems. Factitious disorder differs from a pattern of falsified or exaggerated behavior called malingering. While malingerers make their claims out of a motivation for personal gain, people with factitious disorder have no such motivation.
The "Get up and go" test is most commonly used to assess postural stability. In this test, the physician instructs the patient to stand up from a chair without assistance, walk a short distance, turn around, return, and sit down again. If the patient is unsteady or has difficulties during the test, further evaluation is necessary.
