Bleeding Hemorrhoids

Background: Hemorrhoidal disease is very common in western countries and rectal bleeding is the main symptom complained by patients. Nowadays the ultimate goal of treatment is to block the bleeding with minimally-invasive techniques to minimize post-procedural pain. Objective: The aim of this study is to assess the preliminary results of the emborrhoid technique (embolization of the superior rectal arteries branches) as a new tool for the proctologist to treat severe bleeding hemorrhoids causing anemia. Many categories of patients might benefit from this treatment, such as patients not eligible for conventional surgery, patients not responding to conventional treatment and fit patients with severe bleeding who refused endorectal surgical therapy. Method: From May 2017 to November 2018 a total of 16 patients with chronic rectal bleeding due to hemorrhoids underwent super-selective embolization of the superior rectal arteries at the department of General Surgery in La Spezia, S. Andrea Hospital, Italy. Median age was 59 years. 14 patients were males (87.5 %). Results: No post-procedural and short-term complications were observed at maximum follow up (12 months). The reduction of rectal bleeding with improvement of the quality of life was obtained in 14 patients (87.5%). Conclusion: Our study, although small in number, demonstrates that embolization of superior rectal arteries with coils to treat severe bleeding due to hemorrhoids is safe and effective and does not lead to immediate complications.

Flavonoid Fraction

Hemorrhoidal disease (HD) is common in adults. Treatment is largely conservative, although more invasive procedures may be required. Venoactive drugs such as micronized purified flavonoid fraction (MPFF) are widely used, but a recent and comprehensive review of supporting evidence is lacking. In acute HD, MPFF can reduce HD symptoms such as bleeding, pain, anal discomfort, anal discharge and pruritus. In patients undergoing surgery, postoperative adjunct MPFF consistently reduces pain, bleeding duration and use of analgesia. MPFF treatment is appropriate and effective both as a first-line conservative treatment and as a postoperative adjunct treatment. MPFF reduces the duration of hospital stay following surgery, facilitating a return to normal activity and improving quality of life. MPFF may also prevent HD recurrence.

AbstractHemorrhoidal disease is a highly prevalent anorectal condition causing substantial discomfort, disability, and decreased quality of life. Evidence on preventable risk factors for hemorrhoidal disease is limited. We conducted a cross-sectional study of 194,620 healthy men and women who completed a health screening exam including colonoscopy in 2011–2017. We evaluated potential risk factors of hemorrhoidal disease, including lifestyle factors, medical history, birth history, gastrointestinal symptoms, and anthropometric measurements. The prevalence of hemorrhoidal disease was 16.6%, and it was higher in females than in males (17.2 vs. 16.3%; P < 0.001). Compared to men, the prevalence of hemorrhoidal disease was higher in parous women (adjusted odds ratio [OR] 1.06; 95% confidence interval [CI] 1.02–1.10), and lower in nulliparous women (adjusted OR 0.92; 95% CI 0.86–0.98). In the adjusted analyses, older age, female sex, smoking, overweight, and being hypertensive were independently associated with the presence of hemorrhoidal disease. The prevalence of hemorrhoidal disease was positively associated with body mass index and waist circumference in parous women. The prevalence of hemorrhoidal disease was higher in older age, females, ever-smokers, and hypertensive participants. The association of excess adiposity with the prevalence of hemorrhoidal disease differed by sex and parity.

Aim: Hemorrhoids are very common anorectal conditions, defined as the symptomatic enlargement and distal displacement of the normal anal cushions. The aim of this study was to determine the frequency of hemorrhoids in Madina and Osman Fiqi Hospitals of Mogadishu, Somalia.Methods: The data of all patients with the diagnosis of hemorrhoids who were admitted to Madina and Osman Fiqi Hospitals between January 2012 and December 2015 including demographics, diagnoses, regions of accommodation, and physical examination findings was recorded and analyzed.Results: Among the total study group of 100 patients 57 (57%) were men and 43 (43%) were women with a mean age of 47.6 (range: 35-65) years. According to the regions of accommodation of the patients, it was detected that 52 (52%) patients were from the center of Mogadishu and the remaining lived in other regions. With regard to the physical examination results, 58 (58%) patients were determined to have internal hemorrhoids, while the remaining 42 (42%) patients possessed external hemorrhoids.Conclusions: Hemorrhoidal disease has a peak incidence between the ages of 45 - 65 years for both genders and higher socioeconomic status is associated with increased prevalence. A detailed physical examination is essential for diagnosis. Despite its prevalence and low morbidity, hemorrhoidal disease has a high impact on quality of life, and can be managed with both surgical and nonsurgical treatments.International Journal of Human and Health Sciences Vol. 02 No. 03 July’18.

Introduction: According to the vascular theory arterial overflow in the superior haemorrhoidal arteries would lead to dilatation of the haemorrhoidal venous plexus. The technique helps to promote the obliteration of the terminals of the superior rectal artery. The objective of this study is to describe the results of 100 patients with hemorrhoidal disease treated by the Hemorrhoidal LASER Procedure technique. Method: Under SAB anesthesia terminal arteriole of the upper rectal arteries were fulgurated by fiber laser diode, causing interruption of hemorrhoidal flow. This procedure is repeated circumferentially, following the clockwise positions.This procedure can be performed as a day care surgery. Results: Between January 2018 to January 2019, 100 patients underwent the Hemorrhoidal LASER Procedure technique for hemorrhoidal disease grades I, II and III. Total 100 patients were treated with HeLP procedure. Among them number of men was 81 and female was 19.The procedure proved to be successful at 3 month follow up of 92% patient. No major adverse effects or complications were reported. Post operative minor pain that required medication was 5 cases (5% patient). Postoperative minor bleeding was observed in 3 cases that were managed conservatively. At 3 month after procedure resolution of symptoms were observed in 88% cases with overall satisfaction rate was 89%. Significantly higher quality of life was observed in laser haemorrhoidal procedure. Conclusion: Hemorrhoidal LASER Procedure is a painless outpatient technique .It is a safe, effective, improve symptoms & chance of cure is high compared to other conventional surgery. Similar benefits are seen for patient with severe anal spasm, external thrombosis, fissure and sentinel tags & fistula. J Bangladesh Coll Phys Surg 2020; 38(1): 18-22

Definition Of

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).

Exposure Process

Most production electron beam lithography systems can pattern minimum features a few tenths of a micron across. Linewidth in these systems is usually limited by the quality of the exposing beam and by electron scattering in the resist and substrate. By using a smaller spot along with exposure techniques that minimize scattering and its effects, laboratory e-beam lithography systems can now make features hundredths of a micron wide on standard substrate material. This talk will outline sane of these high- resolution e-beam lithography techniques.We first consider parameters of the exposure process that limit resolution in organic resists. For concreteness suppose that we have a “positive” resist in which exposing electrons break bonds in the resist molecules thus increasing the exposed resist's solubility in a developer. Ihe attainable resolution is obviously limited by the overall width of the exposing beam, but the spatial distribution of the beam intensity, the beam “profile” , also contributes to the resolution. Depending on the local electron dose, more or less resist bonds are broken resulting in slower or faster dissolution in the developer.

Microscopic Investigations

Introduction In electron microscopic investigations of crystalline specimens the direct observation of the electron diffraction pattern gives additional information about the specimen. The quality of this information depends on the quality of the crystals or the crystal area contributing to the diffraction pattern. By selected area diffraction in a conventional electron microscope, specimen areas as small as 1 µ in diameter can be investigated. It is well known that crystal areas of that size which must be thin enough (in the order of 1000 Å) for electron microscopic investigations are normally somewhat distorted by bending, or they are not homogeneous. Furthermore, the crystal surface is not well defined over such a large area. These are facts which cause reduction of information in the diffraction pattern. The intensity of a diffraction spot, for example, depends on the crystal thickness. If the thickness is not uniform over the investigated area, one observes an averaged intensity, so that the intensity distribution in the diffraction pattern cannot be used for an analysis unless additional information is available.

In the observation of a thick specimen by means of a transmission electron microscope, the intensity of electrons passing through the objective lens aperture is greatly reduced. So that the image is almost invisible. In addition to this fact, it have been reported that a chromatic aberration causes the deterioration of the image contrast rather than that of the resolution. The scanning electron microscope is, however, capable of electrically amplifying the signal of the decreasing intensity, and also free from a chromatic aberration so that the deterioration of the image contrast due to the aberration can be prevented. The electrical improvement of the image quality can be carried out by using the fascionating features of the SEM, that is, the amplification of a weak in-put signal forming the image and the descriminating action of the heigh level signal of the background. This paper reports some of the experimental results about the thickness dependence of the observability and quality of the image in the case of the transmission SEM.
