Background: The importance of ACF is not fully explained, however, their number may be a good predictor of synchronous and metachronic adenoma or other polyps whose removal reduces the risk of CRC. Due to the epidemiological and genetic association of ACF with pre-cancer lesions, they may be a potential CRC biomarker. The aim of our study was to show that the number and type of rectal ACF may be a good predictive factor for the presence of polyps located proximally from the splenic flexure and that the type and number of ACF can correlate with the number and specific types of polyps in the large intestine. Methods: The study included 131 patients who underwent colonoscopy combined with rectal mucosa staining with 0.25% methylene blue. The number of rectal ACF was determined and bioptats were sampled for histopathological examination to assess the type of ACF. Endoscopic ACF assessment criteria given by L. Roncucci were used. The obtained material was subjected to statistical analysis using probability distribution, U-test, t-student test, and chi 2 as well as the Statistica 7.1 software package. Results: The study population was divided into three subgroups according to the number of ACF observed, i.e. ACF < 5, 5-10 and > 10. ACF < 5 were found in 35 patients (29.41%), 5-10 ACF in 70 (58.82%) and ACF > 10 in 14 individuals (11.76%). The study revealed the presence of normal ACF (p = 0.49), hyperplastic ACF (p = 0.34), dysplastic ACF (p = 0.11), and mixed ACF (p = 0.06). A single type of ACF was most commonly observed (n = 88, p = 0.74). In the researched group a larger number of ACF is concurrent with adenomas and hyperplastic polyps. The number of ACF clearly correlates with the dysplasia advancement in the adenoma and the number of polyps found. Conclusions: Rectal ACF are a useful marker for the presence of cancerous lesions in the proximal and distal sections of the large intestine.
Background Echinococcosis multilocularis (Hydatid Disease - HD) is a zoonotic disease caused by the larval form of Echinococcus multilocularis (EM). The main sites for this zoonosis are the Middle East, China, India, Alaska, and Siberia. It is rather rare in Europe. In Poland, the Warmian-Masurian Province is the endemic region for Echinococcus multilocularis. The clinical manifestation of the disease is dependent on the location, the size of the cyst and the development stage of the parasite. Considering the uncommon character of echinococcosis in Central Europe, especially such located in the areas outside the liver and lungs, the authors would like to present a case of coexistence in one patient of two EM foci in the liver and the head of the pancreas. Case presentation We present a clinical case of a 32-year-old man who was diagnosed with a cystic lesion with septa and calcification in the sixth segment of the liver and a suspicious change in the head of the pancreas. ELISA Em 2 plus test was positive, Western Blot method - the P-5 pattern showed an image that is characteristic of an EM infection. The sixth liver segment with a tumour and a tumour from the head of pancreas were excised by means of laparotomy. On the 6th day after the surgery the patient was discharged from hospital without complications and in good condition. Currently, he is under the control of a parasitic and zoonotic clinic. He takes an 800 mg daily dosage of Albendazole. Conclusions The presented clinical case shows that if we have a patient with cystic / tumour change in the pancreas and positive immunological tests, CT and MRI of the abdominal cavity are usually sufficient in order to fully diagnose and to qualify such a person for surgery. The most effective treatment is surgical treatment supplemented with pre- and postsurgical treatment with Albendazole.
Introduction: Malaria is still a huge social and economic health problem in the world. It especially affects the developing countries of Africa. A particular problem is the misuse and abuse of over-the-counter antimalarials. This problem could lead to the emergence of drug-resistant strains and the subsequent elimination of more antimalarials from the list of effective antimalarials in Ghana. Methods: During the implementation of the study, an original questionnaire was used to collect data among Ghanaians on their knowledge of malaria, attitude towards antimalarials and their use of antimalarials. Results: The proportion in the analyzed subgroups was compared using the chi-square test. The analysis was conducted using TIBCO Software Inc., Krakow, Poland (2017) and Statistica (data analysis software system), version 13. In total, 86.29% of respondents knew the symptoms of malaria (p = 0.02) and 57.2% knew the cause of malaria (p < 0.001). Respondents with higher education were significantly more likely to know the symptoms of malaria (96%) p < 0.001. In the study group, only 74.59% of the respondents consulted medical personnel before taking the antimalarial drug (p = 0.51) and only 14.2% of the remaining respondents performed a rapid diagnostic test for malaria. Conclusions: The awareness of Accra and Yendi native inhabitants about the causes and symptoms of malaria and alternative ways of prevention is quite high. People’s education very significantly influences the way Accra residents deal with suspected malaria. Widespread public education and awareness and accessibility to places where antimalarial drugs are sold play a very important role in the proper use of antimalarial drugs.
Background: The problem of smoking and its influence on the occurrence of precursors and advanced colorectal cancer is often discussed in the medical literature. Tobacco smoke can provide a non-nutritional source of polycyclic hydrocarbons and other substances which, when combined with an incorrect diet, may play a role in promoting carcinogenesis at the level of the genetic control mechanism. The aim of our study was to assess the effect of smoking on the frequency and type of aberrant crypt foci (ACF) in the rectum and polyps in the large intestine in people who smoke more than 20 cigarettes a day for more than 20 years. Methods and Findings: A colonoscopy combined with rectal mucosa staining with 0.25% methylene blue was performed in 131 patients. Each of the study participants gave informed consent to participate in the study. Three bioptates were collected from the foci defined macroscopically as ACF; in cases where there were fewer foci, the number of collected foci was respectively lower. On the colonoscopy day, patients completed the questionnaire regarding epidemiological data used for analysis of factors affecting the occurrence of ACF in the study group. The number of ACF in the colon was divided into three groups: −ACF < 5, 5 < ACF < 10, ACF > 10. In the statistical analysis, numerical data were presented and real numbers, range of arrhythmic means, mean standard deviation, and results of probability distribution. The Student’s test, U test, and chi2 were applied in order to determine the significance of differences of means and frequency of events in both groups. The level of significance was set at α = 0.05. Statistica 7.1 and Excel 2010 were used. Most smokers are in the age groups between 51–70 years. In the youngest (31–40 years), single ACF appear first (ACF <5) ACF in the number of 5–10 appear a little later (around 50 years of age) and dynamically increase, reaching a maximum at the age of 60–65.ACF in the number >10 appear at the latest age (55 years old) and their number gradually increases with age (linear growth). The probability of occurrence of ACF in all groups is greater in smokers, and the difference for the ACF group 5-10 and ACF >10 is statistically significant with a significance level of p < 0.05. Apart from ACF normal, all types of ACF are more likely in this group than in non-smokers and these differences are statistically significant with p < 0.05. Conclusions: Smoking has a significant impact on the number and type of rectal ACF. Smokers have a greater number of ACFs in the rectum than non-smokers, and the most common type is hyperplastic ACF. Smokers are more likely to develop polyps in all sections of the colon compared to non-smokers.
IntroductionVariations within musculocutaneus nerve (MCN) are very frequent. Such cases should be discussed extensively to reduce the risk of iatrogenic damage during surgery.AimIn this paper, we wanted to present the unusual variability within the brachial plexus, which is the double MCN.Case studyWe present a case of accesory MCN found during the cadaveric dissection.Results and discussionIn this paper we encountered two musculocutaneous nerves, of which MCN proper runs as standard innervating the biceps brachii and the coracobrachialis muscle, while MCN accessory extending distally from MCN proper and innervates the brachialis.ConclusionsThe case analysed by us is rare in the literature. Brachial plexus variations are very common and clinically important.
