Streszczenie:

Anal cancer may be an emerging clinical problem in HIV-infected women particularly in resource-limited settings. Human papillomavirus (HPV) infection is a precursor to anal cancer and is prevalent in HIV-infected women, but the natural history of HPV infection and anal cancer precursors is not well described in this population. It is not known which specific dysplastic lesions in the anus are most likely to progress, and whether treatment of high grade squamous intraepithelial lesion reduces the incidence of anal cancer in women. Cervical HPV infection and associated lesions may be related to

<strong>Abstract</strong> Autogenic training consists of learning a series of concentration exercises that promote relaxation. It is based on the concept of autogenicity and was introduced in the 1930s by Johannes Heinrich Schultz. The technique is based on the self-regulation of normally involuntary functions. Anal Autogenic Training (AAT) is an original variant of the undersigned Author who, referring to the concepts of Schultz applies the Schulz technique to the proctological field and specifically to the situation of Anal Sphincter Syndrome.

Abstract The benefit of treating anal precancerous lesions to reduce anal cancer progression was recently shown in people living with HIV. This will certainly impact the future development of recommendations on anal cancer prevention by including anal precancerous lesions screening and treatment for people living with HIV. However, by bringing this topic to the spotlight, it has also uncovered data that are still missing in this field and that need to be addressed by research. This article will discuss the many unanswered questions about treatment of anal precancerous lesions and future direct

Kukalová-Peck has provided evidence that insect wings evolved from primitively moveable exite lobes of leg podomeres proximal to the coxa. Reinterpretation of previous experimental findings suggests that this hypothesis, as currently formulated, is only partly correct. The costal–subcostal field is derived from an epicoxal exite, but the radial–medial and cubital–anal fields of the wing have arisen from epicoxal endite and (or) subcoxal exite and endite lobes. Wings thus have a complex origin: limb exite plus endite.

Failure is likely the result of inflammation that persists after surgery, and cytokines play an important role in these processes. The aim of the study: evaluate local production and determine the role of IL-6 and TNFα in the formation of rectal fistulas.&#x0D

Visceral leishmaniasis and HIV co-infection presents diagnostic, monitoring and treatment challenges. This is a report of a co-infected patient who developed multiple complications and treatment side-effects, including renal and liver failure, pancytopenia with recurrent sepsis, along with anal cancer, depression and poor quality-of-life spanning over two decades. Urgent research specific to this cohort is needed.

Background/Purpose: This study summarizes the surgical treatment options and their clinical efficacy for postoperative residual rectourethral fistula following anoplasty in patients treated in our department from July 2005 to July 2012. Methods: For 38 cases of postoperative residual rectourethral fistula following anoplasty, according to differences in anal appearance and functionality, either an anterior sagittal or a posterior sagittal surgical rectourethral fistula repair procedure was performed. Results: The residual rectourethral fistula following anoplasty was an obvious tube-like struc

570 Background: Despite potential oncologic gains from using radiotherapy in patients with inflammatory bowel disease (IBD), it has historically been contraindicated due to increased acute gastrointestinal (GI) toxicity. Yet recent published literature is mixed with regards to toxicity outcomes in these patients. In this study, we examine GI, genitourinary (GU), and skin toxicity in IBD patients compared to non-IBD patients both treated with external beam radiation therapy (EBRT) for anal or colorectal cancer (CRC). Methods: Anal and CRC patients who received EBRT were included in this single

Smooth muscle preparations from the circular muscle layer of the most distal rectum and the proximal and distal human internal anal sphincter (IAS) mounted in organ baths to record isometric tension developed spontaneous tension. Transmural electrical field stimulation (TMS) induced frequency- and impulse duration-dependent relaxations sensitive to tetrodotoxin in the stimulation range of 0.5-40 Hz and 0.04-0.6 ms. Poststimulus contractions were most frequent and prominent in rectal preparations. Maximal relaxations were comparable in the three locations and were achieved at 10 Hz and 0.4 ms.

4 Background: Anal cancer is a rare, but treatable, malignancy caused by the human papilloma virus (HPV). Because anal cancer is uncommon and carries a significant social stigma, this disease has rarely been studied in a prospective fashion, creating a large knowledge gap of which biological factors can improve treatment responses, particularly the microbiome which regulates many facets of oncobiology. Methods: We collected microbiome samples before, during, and after definitive chemoradiation for localized anal cancer as part of an IRB-approved institutional clinical trial (2017-0606). Sample

<strong>SUMMARY</strong> The greatest ignorance in Medicine is probably in the field of anal diseases. The competence index of a Proctologist is inversely proportional to the number of times he repeats the term “hemorrhoids”. The real hemorrhoidal plexuses (internal) are normal anatomical structures that play an important physiological role in perfecting continence in synergy with the sphincter system. The so-called “hemorrhoids” represent a popular myth for patients and a serious educational gap in the training of the Doctor and the Surgeon. In reality, “hemorrho

Field trials were conducted in central Australia to evaluate the ability of various olfactory lures to attract feral cats (Felis catus L.). Ten food-based lures, one plant extract and two scent-based lures (anal-gland preparations from male and female cats) were evaluated on the basis of visitation rates and elicited behavioural responses. A visual lure composed of bird feathers was also tested in conjunction with the scent-based lures. One food-based lure (sun-rendered prawn) and both of the scent-based lures were found to attract feral cats. The visual lure did not enhance the attractiveness

For this purpose, the mid intestine was dissected out and placed in a partitioned bath. Balloon distension (0.1&shy;0.4 ml) and intramural field stimulation (8 Hz, 10 V) were carried out and the responses of the circular muscle were recorded 1.5 cm orally and anally to the stimulus using force transducers. The preparations developed spontaneous contractions propagating in the anal direction with a frequency of about one contraction per 2 min. Distension of

A knowledge of the taxonomy of the Atlantic redfishes, Sebastes spp., and techniques for their field identification are essential prerequisites for rational management of their fishery, but both remain poorly known. Through analysis of a set of morphological data for Sebastes fasciatus and S. mentella of the Scotian Shelf, using multivariate techniques, I examined the potential of 15 characters as field identifiers. Although the species are significantly different, they cannot be fully separated using these characters. I suggest that electrophoretic techniques are needed for precise identifica

BACKGROUND Trans-anal endoscopic microsurgery (TEM) enables a good visualization of the surgical field and is considered the method of choice for excision of adenomas and early T1 rectal cancer. The rectum and retro-rectal space might be the origin of uncommon neoplasms, benign and aggressive, certain require radical trans-abdominal surgery, while others can be treated by a less aggressive approach. In this study we report outcomes in patients undergoing TEM for rare and non-adenomatous rectal and retro-rectal lesions over a period of 11 years. AIM To report outcomes in patients undergoing TEM
