Floor Function

Background: Functional disorders of the pelvic floor are a common clinical problem. Diagnosis and treatment of these disorders, which frequently manifest with nonspecific symptoms such as constipation or incontinence, remain difficult. MR Defecography has emerged over the last decade as a modality which additionally images the pelvic floor function in real time besides combining the advantages of previously used modalities and that of magnetic resonance i.e. multiplanar imaging, good temporal resolution and lack of radiation exposure.  Dynamic MRI defecography is a relatively new imaging protocol which can be extremely useful in identification of anatomic and functional pelvic floor dysfunction such as organ prolapse, anismus and fecal incontinence. Excellent demonstration of the perirectal soft tissues allows assessment of spastic pelvic floor syndrome and descending perineum syndrome and visualization of enteroceles. The aim of the study was to assess causes of pelvic floor dysfunction.Methods: Authors evaluated 25 patients with cine Magnetic Resonance Defecography at our center between December 2018 and 15th May 2019. MR Defecography was done with help of 3 Tesla Somatom Seimens MRI. Ultrasound jelly was instilled into the rectum of patient via a short flexible tube while the patient lies in the lateral decubitus position on the scanner table before being moved into the gantry and was asked to defecate when instructed. Scanning was done in four phases-resting, straining, squeezing and defecation as per the standard protocol while patient lied supine.Results: Most common complaint encountered was that of constipation. Patients in age group 20-70 years were studied. Maximum patient were of the age group 40-50 years. Most common finding was organ prolapse in total 9 patients with anterior rectocele in 6 patients followed by rectal prolapse.Conclusions: Magnetic resonance defecography is an excellent modality for assessment of pelvic floor disorders.  It has very good temporal resolution and high soft tissue contrast, also allows visualization of the pelvic floor function in real-time without any radiation load. Imaging the defecation process in real-time leads to a definitive diagnosis in cases of dysfunctional defecation and a precise diagnostic and pre-operative assessment in cases of organ prolapse.

AbstractObjectiveTo describe a new dynamic echodefecography(EDF) using BK ultrasound 8838 transducer and compare its testing results with X-ray defecography.MethodThe BK 8838 ultrasound probe is used to evaluate the static 3D scan, dynamic 3D scan and dynamic 2D scan of pelvic floor and compare its testing results with X-ray defecography and defined its value to evaluate the pelvic floor disease.ResultsFifty-seven patients were studied (24 male and 33 female). Forty seven patients were diagnosed as anismus by EDF and 46 patients were diagnosed as anismus by X-ray defecography. Sixteen patients were diagnosed as rectocele by X-ray defecography, among which eight were classified as mild(6-15mm), 4 as moderate(16-30mm) and 4 as severe(over 30mm).Fourteen patients with constipation and 2 patients with anal pain were diagnosed as intussusception by EDF, but only 3 patients were diagnosed as intussusception by X-ray defecography. Two patients with constipation were diagnosed as perineal descent by EDF and none by X-ray defecography. Two patients were diagnosed as enterocele by EDF as well as X-ray defecography.ConclusionThe EDF established by BK 8838 ultrasound probe can show clear anatomy and real time movement of pelvic floor muscle. The EDF is more sensitive to the diagnosis of intussusception, perineal descent(PD) and anal spincter defect than X-ray defecograpgy. For anismus,rectocele and enterocele,the diagnosis results are comparable between EDF and X ray defecography. Further study is needed to determine its clinical values to evaluate the pelvic disease.

Quiescent Prominence

This paper describes some recent results of our quiescent prominence spectrometry program at the Mees Solar Observatory on Haleakala. The observations were made with the 25 cm coronagraph/coudé spectrograph system using a silicon vidicon detector. This detector consists of 500 contiguous channels covering approximately 6 or 80 Å, depending on the grating used. The instrument is interfaced to the Observatory’s PDP 11/45 computer system, and has the important advantages of wide spectral response, linearity and signal-averaging with real-time display. Its principal drawback is the relatively small target size. For the present work, the aperture was about 3″ × 5″. Absolute intensity calibrations were made by measuring quiet regions near sun center.

Capture Techniques

We have employed cryoelectron microscopy to visualize events that occur during the freeze-drying of artificial membranes by employing real time video capture techniques. Artificial membranes or liposomes which are spherical structures within internal aqueous space are stabilized by water which provides the driving force for spontaneous self-assembly of these structures. Previous assays of damage to these structures which are induced by freeze drying reveal that the two principal deleterious events that occur are 1) fusion of liposomes and 2) leakage of contents trapped within the liposome [1]. In the past the only way to access these events was to examine the liposomes following the dehydration event. This technique allows the event to be monitored in real time as the liposomes destabilize and as water is sublimed at cryo temperatures in the vacuum of the microscope. The method by which liposomes are compromised by freeze-drying are largely unknown. This technique has shown that cryo-protectants such as glycerol and carbohydrates are able to maintain liposomal structure throughout the drying process.
