This study presents three cases of cystic adventitial disease, a rarely occurring vascular pathology that mainly affects the arteries. The nature of the disease consists in the occurrence of adventitial cysts filled with mucous, and leads towards vascular destruction and stenosis as well as limb ischemia. The popliteal artery is most often concerned in this etiology, and male patients predominate. However, the etiology of the disease remains unknown. One can observe a similar chemical content of adventitial and Baker's cysts, and their occurrence near the joints. Adventitial cystic disease may result in atypical intermittent claudication. This disease is characterized by the absence of pulse during flexion of the knee joint. Duplex color ultrasonography plays an important role in the diagnosis of the disease, as well as arteriogaphy, where one can observe hourglass or semilunar vascular lumen stenosis. Surgical management is the method of choice. This study presents three cases of cystic adventitial disease. Two cases concerned the popliteal artery and one the common femoral artery. All three patients were male with symptoms of lower limb ischemia. The three patients underwent surgical treatment and were diagnosed with cysts - localized intravascularly - that were constricting the vessels and filled with a jelly-like content. Two patients with significant lesions required surgical excision of the changed vascular fragment and bypass grafting. The third patient was subjected to local cyst excision. Percutaneous cystic content aspiration is also a method of treatment.

The aim of this study was to assess short-term outcomes of surgical treatment of pancreatic cystic tumors (PCTs). Material and methods: We retrospectively reviewed medical records of 46 patients (31 women and 15 men) who had undergone surgery for pancreatic cystic tumors in our department. Results: Pancreatic cystic tumors were located within the pancreatic head (21), body (11), tail (13), and whole pancreas (1). The following surgical procedures were performed: pancreatoduodenectomy (20), central pancreatectomy (9), distal pancreatectomy (3), distal pancreatectomy with splenectomy (3), distal extended pancreatectomy with splenectomy (2), total pancreatectomy (1), duodenum preserving pancreatic head resection (1), local tumor resection (4), and other procedures (2). Histopathological tumor types were as follows: serous cystadenoma (14), intraductal papillary mucinous adenoma (5), intraductal papillary mucinous carcinoma (5), solid pseudopapillary tumor (5), mucinous cystadenoma (5), mucinous cystadenoma with border malignancy (1), mucinous cystadenocarcinoma (2), adenocarcinoma (4), and other tumors (5). Early postoperative complications were observed in 14 (30.43%) patients. Reoperations were performed in 9 (19.56%) patients. The perioperative mortality rate was 6.52%. Conclusions: Serous cystadenoma was the most common pancreatic cystic tumor in the analyzed group. PCTs were most frequently located within the pancreatic head. Pancreatic resection was possible in most patients, and pancreatoduodenectomy was the most common pancreatic resection type.

Lymphangiomas constitute a group of very rare diseases and occur with a frequency of 1/250,000 to 1/20,000 of hospitalizations. Even though they are benign lesions, their complications may turn into a life-threatening condition. They usually occur in children (90%), they are either congenital or they appear before the child’s second birthday. Occassionally they are found in adults. Lymphangiomas are usually localized around neck, but also near armpits and in the groin area. Less than 1% of lymphagiomas are detected in the retroperitoneal space and intestinal mesentery. Vascular lesions derived from lymphatic vessels can be divided into ordinary ones, usually known as capillary, cavernous, and cystic. The cystic tumor (lymphangioma mesenteri) is the least common. It occurs mostly in the retroperitoneal space, mesentery of the colon, or extremely rarely in the mesentery of the small intestine. Preoperative diagnosis is difficult due to non-specific clinical symptoms and noncharacteristic image in the diagnostic tests. Lymphangioma complications, such as intestinal obstruction or perforation, and persistent pain, are the cause of exploratory laparotomy. Final diagnosis requires microscopic examination of material collected during an operation. This article presented the case of a 40-year-old female, operated due to the obstruction of the gastrointestinal tract, in whose case the lymphangioma was recognised in postoperative histopathological examination of the tumor from the jejunal mesentery. Since patients with these tumors have good chances of complete recovery - if there are no serious complications - it appears that the optimal therapeutic procedure should be early surgery, which reduces the possibility of complications.

Autosomal dominant polycystic kidney disease is the most common genetic cause of renal failure. Apart from kidney involvement, patients are at risk of extra-renal manifestations, including vascular lesions. The etiology of vascular changes is diverse and depends, among other factors, on polycystin gene mutation, increased activity of the renin-angiotensin-aldosterone system and the occurrence of hypertension. The observed vascular system complications include cerebral artery aneurysms, cervico-encephalic arteries' dissection, aortic aneurysm and dissection and intracranial arterial dolichoectasia. This article discusses the etiopathogenesis, symptomatology, principles of prevention and treatment of the aforementioned diseases of the vascular system accompanying polycystic kidney disease.

Intracystic fluid pressure is discussed as a potentially important factor influencing a bone cyst growth. This process can develop in the course of months. However, the exact mechanism remains speculative. In this paper, we use an established mathematical model to evaluate whether the presence of pressurized fluid in bone cavities may result in cyst growth. A continuous function of bone density rate vs. mechanical stimulus is used. The numerical model of the mandible with the cyst is used to predict the stress-stimulated change in bone density around the cavity.

The distribution and abundance of dinoflagellate cyst assemblages were investigated in surface sediments from south-western Red sea coasts of Saudi Arabia at six sites during March 2010. A total of 19 taxa of dinoflagellate cysts were identified from all sites. The sampling sites showed a similar cyst assemblage, but they differed in total cyst abundance (3 to 4083 cysts g-1 dry weight). Cyst abundance was strongly correlated with sediment characteristics, the highest numbers being recorded in sediments with large contents of organic carbon, silt and clay. Cyst assemblages were dominated by cysts of potentially toxic species, including Cochlodinium polykrikos, Prorocentrum minimum, Dinophysis acuminata, Alexandrium catenella and Scrippsiella trochoidea. Most cysts germinated successfully at different rates at 15 and 25°C. This study suggests that surface sediments from all Saudi Red Sea coasts should be monitored for the presence of dinoflagellate cysts to give ample warning of the presence and abundance of toxic species in a given area

Introduction: Detection of the frequency of pancreatic cystic lesions has increased in the recent years. The majority are pseudocysts, the remaining cysts are mainly neoplasms. Proven risk of malignancy affects intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms (MCN). The aim of this study was to analyze clinical data of patients with pancreatic cysts or pancreatic cystic neoplasms on operate at Department of General and Transplant Surgery in the Barlicki Hospital in Lodz. Material and methods: In 2007-2016, there were 145 patients operated on at the Department of General and Transplant Surgery in Barlicki Hospital in Lodz, due to pancreatic cystic lesion. The type of operation, histopathological diagnosis and basic demographic data were analyzed. Results: Non-neoplastic cyst (mainly pseudocysts) was found in 66.9% of patients, neoplasms were detected in 33.1%. The mean age was significantly higher in patients with neoplasm than without neoplasm (57.06 years vs. 50.88 years, p=0.009). Neoplastic cyst occurred more frequently in women (68.75% of women, 31.25% of men, p=0.001). Malignant tumor was found in 14.58% of neoplasms cases and in 4.83% of all pancreatic cystic lesions. Conclusions: According to the analyzed material, there is a significant risk of malignancy in patients with pancreatic cyst. Neoplastic cysts are more common in women. Discussion: Pancreatic cystic tumors are treated mainly by resections of pancreas. In case of benign lesions with low risk of malignancy, there are less extensive operations performed, such as enucleations of lesions. There are no guidelines that could be used satisfactorily in follow up of patients with pancreatic cysts.

Naczyniaki limfatyczne są bardzo rzadkimi guzami krezki jelita cienkiego. Zazwyczaj lokalizują się w okolicy głowy oraz szyi i diagnozowane są głównie u pacjentów pediatrycznych. Zmiany te rozpoznawane u dorosłych są wyjątkową rzadkością. Prezentowany przypadek dotyczy 46-letniego pacjenta operowanego w 2012 r. na Oddziale Chirurgii Ogólnej i Małoinwazyjnej Szpitala Zakonu Bonifratrów w Krakowie. Chory zgłaszał trwające od około 3 lat wzdęcia brzucha z okresowymi nudnościami. W badaniu przedmiotowym brzucha stwierdzono w podbrzuszu nieruchomy opór o średnicy ok. 10 cm. Ultrasonografi a oraz tomografi a komputerowa jamy brzusznej wykazały obecność płynowej zmiany torbielowatej w podbrzuszu o wymiarach 117 x 58 x 159 mm. W takcie laparoskopii oraz późniejszej laparotomii stwierdzono torbiel krezki jelita cienkiego wypełniającą podbrzusze środkowe oraz lewe. Zmianę wypreparowano oraz wycięto – materiał wysłano do badania histopatologicznego. Torbiel zawierała ok. 700 ml białego płynu. Po uzyskaniu wyniku badania histopatologicznego powzięto, po ponownym kontakcie z patomorfologiem, podejrzenie naczyniaka limfatycznego. Pacjent po okresie rekonwalescencji po zabiegu operacyjnym został pouczony o konieczności okresowej kontroli z uwagi na możliwość nawrotów. Powyższy przypadek potwierdza przypadkowość i trudność rozpoznania naczyniaka limfatycznego. Dodatkowo – jak pokazują pojedyncze przypadki opisywane w piśmiennictwie polskim oraz światowym – niezwykła rzadkość tego schorzenia utrudnia właściwe postępowanie diagnostyczne.

Lymphangiomas are very rare, mesenteric tumours in the small intestine. Usually, they are found in the head or neck and are mainly diagnosed in paediatric patients. These tumours appear in adult patients, but are extremely rare. We report on a 46-year-old patient who was operated on in 2012 at the General Surgery Department of St. Jan Grande Hospital in Krakow. The patient presented with chronic abdominal pain and with episodes of nausea for 3 years. Physical examination revealed a 10 cm mass in the lower part of abdomen. Imaging studies, ultrasonography and a CT-scan, showed a large (117 x 58 x 159 mm) cyst in the abdomen. During surgery, a giant small intestine mesenteric cyst was found in the medial and left lower part of the abdomen. The tumour was enucleated and sent for histopathology examination. The cyst contained about 700 ml of a milk-like fl uid. After histopathology tests, lymphangioma was diagnosed. The patient was instructed about the necessity of regular check-ups due to the risk of recurrence. This case confi rms that diagnosis of lymphangioma is usually accidental. In addition, the rarity of this tumour makes the right diagnostic procedure even more diffi cult to achieve.

Globodera artemisiae (Eroshenko et Kazachenko, 1972) was found in Poland in autumn of 2004. The nematodes developed on Artemisia vulgaris L. Morphological and morphometric characteristics of the Polish population correspond to earlier known populations from Far East of Russia, Armenia, China, Germany and Sweden. The traditional identification was confirmed by molecular methods. On the basic of rDNA sequences of G. artemisiae, deposited in GenBank the product of expected size was obtained. Subsequently, the results were confirmed by sequencing analysis.

Alexandrium minutum cysts were studied in sediment cores from its type locality, the Eastern Harbour of Alexandria, following the disappearance of the species from the plankton since 1994. Three cores were sampled in the summer of 1999 along the north-south axis of the harbour. The sediments were subjected to grain size analysis and their organic carbon content was determined. The sediments consisted of medium, coarse and very coarse sand. Grain size and organic carbon content were negatively and significantly correlated in core 1 but followed a parallel trend in cores 2 and 3. Seven dinoflagellate cysts, representing 6 genera were identified from the cores. Their relative abundance showed a remarkable difference. A. minutum cysts contributed a maximum of 17.4% to the total cysts. The distribution profile of A. minutum cysts in the cores reflects the bloom duration but not its productivity. The cyst distribution in the cores is the resultant of two opposite processes, the sedimentation rate and the continuous erosion of the bottom sediments, which is not related to sediment texture.

Pierwotniaki pasożytnicze z rodzajów Cryptosporidium i Giardia nie są elementem kontroli jakości wód powierzchniowych, na których usytuowane są kąpieliska. W pracy podjęto ocenę częstości występowania tych pierwotniaków w wybranych wodach powierzchniowych wykorzystywanych do rekreacji na terenie województwa mazowieckiego. Dodatkowo oznaczono wartości wskaźników mikrobiologicznych (E. coli, enterokoki) oraz zawartość przetrwalników klostridiów redukujących siarczyny. Badania potwierdziły obecność Cryptosporidium sp. i Giardia sp., odpowiednio w 65% i 95% badanych próbek wody. Średnia liczba wykrytych pierwotniaków Cryptosporidium sp. wynosiła 0,11 oocyst w 1 dm3, a Giardia sp. 0,31 cyst w 1 dm3 wody. Źródłem (oo)cyst w wodzie mogły być zanieczyszczenia rolnicze, a także nieuregulowana gospodarka ściekowa gospodarstw położonych w pobliżu kąpielisk. Liczba spor klostridiów redukujących siarczyny (wskaźnik nienormowany) nie przekraczała 50 jtk/100 cm3. Wyniki wykonanych oznaczeń wskazały na celowość rozszerzenia zakresu rutynowych badań mikrobiologicznych wody przeznaczonej do rekreacji o te wskaźniki sanitarne w celu poprawy bezpieczeństwa zdrowia ludzi.

Monitoring of protozoan parasite species, Cryptosporidium and Giardia, is not covered by quality control system of surface waters in designated swimming areas. The objective of this study was to assess the prevalence of these protozoa in the selected surface waters used for recreational activities in Masovian voivodship. In addition, microbiological parameters (E.coli, enterococci) as well as the spore content of sulphite-reducing clostridia were determined. The studies confirmed the presence of Cryptosporidium sp. and Giardia sp. in 65% and 95% of tested water samples, respectively. The average number of detected Cryptosporidium sp. oocysts was 0.11 oocysts per 1 dm3, while of Giardia sp. – 0.31 cysts per 1 dm3 of water. The source of protozoan oocysts could be agricultural contamination as well as unregulated processes of wastewater management at farms located near the swimming areas. The spore number of sulphite-reducing clostridia (non-standardized parameter) did not exceed 50 cfu/100 cm3. The study results confirm that it is purposeful to extend the routine microbiological testing methodology of recreational water by the discussed sanitary indicators in order to improve health security of the population.
