    Introduction: Hydatid cyst is a zoonotic disease seen in endemic areas. It is an important health problem in our country and especially in our Eastern and South-eastern Anatolia Region. Involvement of isolated breast tissue is very rare in hydatid cystdisease. As far as we know, isolated recurrent breast cyst hydatidosis has not been found in the literature. We aimed to present the case of a patient who was diagnosed with recurrent isolated cyst hydatid in the same breast, operated on because of hydatid cyst in the right breast 9 years ago. A hydatid cyst should be considered, particularly in endemic regions, in the differential diagnosis of cystic masses of the breast. If the patient has previously undergone surgery for breast cyst hydatid disease, recurrent cyst hydatid disease should be considered at the differential diagnosis. Celsius.

    Full Text Available Hydatid disease continues to be a common surgical condition in many rural parts of India, carrying a significant morbidity and mortality. Hydatid liver disease affects all age groups, both sexes equally, and no predisposing pathologic conditions are associated with infection . Echinococcosis, is a zoonosis that occurs primarily in sheep - grazing areas of the world Humans contract the disease from dogs, and there is no human - to - hum an transmission it is limited geographically to areas where close and continuous contact exists between domesticated carnivores such as the dog and ungulates such as cattle and sheep. AIM: This study aims to evaluate the incidence of important risk factors of contact history in the patients presented with abdominal hydatid disease and also treatment modalities followed. MATERIAL AND METHODS: It is a prospective & analytic study was conducted by selection of patients admitted in the wards of the department o f general surgery of a tertiary care hospital.

    Hydatid disease (HD) may develop in almost any part of the body. The liver is the most frequently involved organ (75 %), followed by the lung (15 %) and the remainder of the body (10 %). Hydatid cysts with unusual localizations may cause serious problems in the differential diagnosis. In this article the various imaging findings of hydatid cysts with unusual localizations are reviewed, based on our experience. Findings in brain, heart, pericard, kidney, intraperitoneum, retroperitoneum, bone, soft tissue, and breast are discussed. Hydatid disease should be considered in the differential diagnosis of all cystic masses in all anatomic locations, especially when they occur in areas where the disease is endemic. The combination of clinical history, imaging findings, and serologic test results usually help the diagnosis. (orig.)

    Purpose: The purpose of this study was to present the CT findings of complicated pulmonary hydatid cysts on the basis of the CT appearances. Material and Methods: Preoperative CT examinations of 19 cases with hydatid cysts were evaluated retrospectively for the number and various features of the cysts and secondary changes in adjacent structures. The results were compared with surgical findings. Results: While 7 patients had multiple pulmonary hydatid cysts, 12 patients had solitary cyst. The total number of the cysts was 29. Eleven of them were intact cysts. Two of the 18 complicated cysts were only ruptured, while the remaining 16 complicated cysts were ruptured and infected. The endocyst was separated from a pericyst in a local area in one ruptured cyst. Air-bubbles were seen within 14 infected cysts. Nine of the infected cysts had characteristic appearances of hydatid disease. The other 2 infected cysts showed soft tissue density. Conclusion: CT can provide the specific diagnosis of pulmonary hydatid cysts by demonstrating the number and features of the cysts, characteristic appearances of complicated cysts, and secondary changes in adjacent structures. Whether there are characteristic signs or not, the demonstration of air-bubbles within the cyst, together with ring enhancement, are strong indicators for infected hydatid cysts. (orig.)

    Hydatid disease is mostly located in the liver. It then has a characteristic appearance allowing a definite diagnosis by means of ultrasound and/or CT examination. Isolated extrahepatic infestation is much less common. We report a number of cases of hydatid cysts in the tail of the pancreas, the adrenal, the spleen, and in bones and muscles. With reference to these examples we discuss the potential usefulness of radiological examination for the diagnosis and also its limitations and the pitfalls that may be encountered.

    Recurrence of hepatic hydatid disease is still a serious problem in endemic areas like our country. In this study, we present the causes and management of recurrences after surgical therapy of the hepatic hydatid cysts. Hepatic hydatid cyst patients treated surgically and followed afterward at Istanbul University, Cerrahpasa Medical Faculty, Department of General Surgery between January 1998 and January 2003 were evaluated retrospectively. During this period, 172 primary patients with hepatic hydatid disease were attended to at our clinic. Morbidity and mortality rates for this series were 5.8% and 0.58%, respectively. Recurrence rate was 4.65% during the follow-up period of 60.5 months (range, 25-84 months). Primary causes of recurrence were thought to be unnoticed cysts with exophytic development due to inadequate incision and exposition and spreading of the disease during conservative operative interventions. It is concluded that selection of the proper incision allowing complete exposition, and performance of pericystectomy in solitary, peripherally located cysts prevent recurrence.

    A 27 year old woman who presented with upper abdominal pain was found on ultrasonography to have multiple liver cysts consistent with hydatid disease. Three years previously she had undergone evacuation of multiple infected liver cysts thought to be due to hydatid disease. Computed tomographic scanning supported the diagnosis of hydatid disease affecting the right lobe of the liver. At laparotomy the right lobe contained multiple cysts which were removed by right lobectomy. Histology revealed congenital dilatation of the intrahepatic bile ducts with fibrosis (Caroli's disease) but no evidence of hydatid disease. Images Figure 1 Figure 2 PMID:2057431

    To report the integrated progress of the hydatid disease information management system, and to provide the reference for further system improvements by analysis of results on simulation test feedback. The work of institutional code matching by collecting fundamental and integrated information of the system in epidemic areas of hydatid disease was carried out, and professional control agencies were selected to carry out the simulation test. The results of agencies code matching at stage indicated the average completion rate was 94.30% on administrative agencies, 69.94% on registered professional agencies and 56.40% on professional institutions matching related to hydatid disease prevention and control implements in seven provinces (autonomous regions) and Xinjiang Production and Construction Corps. Meanwhile, the response rate of open-ended proposals was 93.33% on fifteen feedbacks, and the statistics showed 21.43% believed the system was low fluency, 64.29% considered the system was inconvenience for data inputs and 42.86% considered it would be improved on system statistics functions, of which 27.78% were provincial users, 22.22% were the city users and 50.00% were the county users. The hydatid disease prevention information management system meets the fundamental needs of the majority agencies in hyperendemic areas of echinococcosis, it needs to develop the further test with more agencies joining after the work of the institutional code matching completion and the system service improvement in the next stage.

    Cerebral hydatid disease is very rare, representing only 2% of all cerebral space occupying lesions. The diagnosis is usually based on a pathognomonic CT pattern. Exceptionally, the image is atypical raising suspicion of many differential diagnoses such as intracerebral infectious, vascular lesions, or tumors. We report 2 atypical cases of cerebral hydatid cysts diagnosed in a 21, and a 24-year-old woman. The CT scan results suggest oligodendroglioma in the first case and brain abscess in the second. An MRI was helpful in the diagnosis of the 2 cases. Both patients underwent successful surgery with a good outcome. The hydatid nature of the cyst was confirmed by histology in both cases.

    Hydatid disease, a worldwide zoonosis, is caused by the larval stage of the Echinococcus tapeworm. Although the liver and the lungs are the most frequently involved organs in the body, hydatid cysts of other organs are unusual. Radiologically, they usually demonstrate typical imaging findings, but unusual imaging characteristics of complicated cyst of hydatid disease, associated with high morbidity and mortality, are rarely described in the literature. The purpose of this study is to review the general features of hydatidosis and to discuss atypical imaging characteristics of the complicated hydatid disease in the human, with an emphasis on structure and rupture of the cystic lesion as well as ultrasonography (USG), computed tomography (CT), and magnetic resonance imaging (MRI) features of the disease. In our study, the available literature and images of the cases with complicated hydatidosis involving liver, lung, brain, spine and orbit were reviewed retrospectively. In hydatid disease, there are many potential local and systemic complications due to secondary involvement in almost any anatomic location in humans. Radiologically, in addition to the presence of atypical findings such as perifocal edema, non-homogenous contrast enhancement, multiplicity or septations and calcification, various unusual manifestations due to rupture or infection of the cyst have been observed in our cases with complicated hydatid disease. To prevent subsequent acute catastrophic results and the development of recurrences in various organs, it should be kept in mind that complicated hydatid cysts can cause unusual USG, CT, and MRI findings, in addition to typical ones, in endemic areas. Therefore, familiarity with atypical radiological appearances of complicated hydatid disease may be valuable in making a correct diagnosis and treatment.

    Pelvic masses, especially hydatid disease, rarely present with sciatica. We present the computed tomography (CT) and the magnetic resonance imaging (MRI) findings of a 49-year-old female patient with presacral hydatid disease, who was evaluated for her sciatica. We also want to emphasize the importance of assessing the pelvis of patients with symptoms and clinical findings that are inconsistent and that cannot be satisfactorily explained by the spinal imaging findings. isc herniation in the lumbar spine is a well-known etiology of back pains and sciatica, but whenever disc herniation of the lumbar spine is excluded by the employed imaging modalities, then the pelvis should be examined for other possible etiologies of nerve compression. We describe here a patient, who was complaining of sciatica, with no abnormal findings in her lumbar spinal magnetic resonance imaging (MRI). The cause of her sciatica was found to be associated with a pelvic hydatid cyst compressing the lumbosacral nerve plexus. In conclusion, if no pathology is evident for the lumbar discal structures, in connection with the cause of sciatica and lumbar back pains, then the pelvis should also be examined for the possible etiologies of compression of the lumbosacral nerve plexus. Whenever a multiseptated cyst is come across in a patient of an endemic origin with a positive history for hydatid disease like surgery, indicating recurrence, hydatid cyst is the most likely diagnosis.

    Hepatic hydatid disease is still a commonly seen problem in endemic areas as well as in our country. There is a wide spectrum of therapeutic modalities ranging from simple medical treatment to radical liver resection. Progress in laparoscopic procedures made it possible to consider laparoscopic approaches in selected patients with hepatic hydatid disease. The current laparoscopic approach seems to be limited to cystotomy and drainage. There are fewer reports on hepatic resections or pericystectomy in the literature. In this article we present a case of laparoscopic pericystectomy performed in a selected patient.

    We report a case of splenic hydatid cyst, an unfrequent localization of hydatid disease that usually presents with hydatid cysts in other organs (but not in this case). Primary spleen infestation generally occurs trough arterial blood supply, after the oncosphere of Echinococcus granulosus travels from host's digestive tube to the left atrium, passing trhough hepatic and pulmonar filters; other routes are also possible. Migration of an abdominal hydatid cyst into the thoracic cavity (phenomena called abdominal thoracic hydatid transit) occurs in 3.5% to 5% of liver cysts, and is quite exceptional in splenic cysts. Clinical manifestations are mainly thoracic, the diagnosis is based on serological tests and imaging studies, and surgical treatment is always required. Taking advantage of this unusual case, we remember the pathogenesis of splenic hydatid disease as well as the pathophysiology of transdiaphragmatic transit of abdominal hydatid disease.

    Full Text Available Introduction: The hydatid disease most often involves the liver and the lungs. The disease can involve any part of the body except the hair, teeth and nails. Primary extrahepatico-pulmonary hydatid cysts are rare and only a few sporadic cases have been reported. Materials and Methods: Two hundred and forty-four patients with hydatid cysts managed surgically from January 2005 to December 2009 were evaluated retrospectively. Fourteen (5.7% patients had isolated involvement of the atypical sites, while six (2.4% also had a primary involvement of liver. Results: The cysts were present in gall bladder (0.4%, peritoneum (1.6%, spleen (1.6%, ovary (0.4%, subcutaneous (0.8%, seminal vesicle (0.4%, spinal (0.4%, pancreas (0.4%, kidney (0.4%, mediastinal (0.4%, muscle (0.4%, and brain (0.8%. Discussion and Conclusions: Involvement of sites other than liver and lungs by hydatid disease is rare. Symptoms are related to size, location or possible complication of the cyst. It should be strongly suspected in differential diagnosis of all abdominal cysts especially in an endemic area. Proper surgical and medical management to avoid any recurrences, and a regular follow-up, are of utmost importance to detect any late complications such as local recurrence of the disease and development of hydatidosis at the primary sites.

    Full Text Available Hydatid disease is a serious medical problem in Mediterranean and particularly among sheep farming countries, caused by larval stages of dog tapeworms belonging to the genus Echinococcus. Hydatid cysts may affect every organ in the human body; however, multiple organ involvement (spleen, adrenal gland, heart, pericardium, intravascular growth of hydatids and brain without affecting the two major filters in the body liver and the lung was very rare. In this case, myocardial hydatid cyst is considered as primary and involvement of other organs such as brain, spleen, adrenal glands, and vascular involvement are considered as secondary involvement due to the rupture of hydatid in heart. Rarity of this atypical presentation of hydatid disease leads to this case report.

    Hydatid disease, a worldwide zoonosis, is caused by the larval stage of the Echinococcus tapeworm. Although it can involve almost every organ of the body, lung involvement follows in frequency the hepatic infestation in adults and is the predominating site in children. Radiologically, hydatidosis usually demonstrates typical findings, but many patients are at risk of developing various complications of hydatid disease with atypical imaging findings and these are rarely described in the literature. In this pictorial review, the imaging features of local complications of hydatid disease involving the thorax including intrapulmonary or pleural rupture, infection of the ruptured cysts, reactions of the adjacent tissues, thoracic wall invasion and iatrogenic involvement of pleura are described. Additionally, imaging characteristics of transdiaphragmatic thoracic involvement of hepatic hydatid disease are presented. To prevent the development of subsequent catastrophic results, all radiologists need to be aware of the atypical imaging appearances of complications of pulmonary hydatid disease.

    Human hydatid disease, or echinococcosis, is a helminthic infection that leads to the formation of fluid-filled cysts in the liver, lungs and other organs. Breast, is a rare primary site of hydatid disease. We report a case of a 45 years old female who presented with a breast lump of 2 years duration. On fine needle aspiration cytology a diagnosis of fibrocystic changes of the breast was made and ultrasonography breast showed a thick walled infected cystic lesion. Intraoperatively, a diagnosis of hydatid cyst was made which was confirmed on histopathology.

    Full Text Available Hydatid disease is one of the oldest diseases known to mankind. In 85-95% of the cases, the liver and/or the lung are involved and in only 5-15% the cyst occurs at the other sites. Echinococcal cysts are mostly found in the liver (60%-70% of cases, followed by the lungs (10%-25%, spleen, ovaries, kidneys, brain, bones and heart, but rarely elsewhere in the body. 1-3 Retroperitoneal location of hydatid cyst is encountered rarely and only occasional case reports have appeared since Lockhart and Sapinza first reported this entity in 1958. 4-6 Primary retroperitoneal hydatid cyst is extremely rare. Hydatid disease in extrahepatic locations usually remains asymptomatic unless the cyst grows and produces.

    Hydatid disease (HD) is a parasitic infection caused by the larvae of a tapeworm that is endemic to many regions around the world-South America, Africa, and Asia, in particular. Humans are infected as intermediate hosts in the parasite's life cycle; thus, HD can be seen in persons living in areas where animal husbandry is practiced. However, owing to the varied patterns of migration and immigration during the past several decades, HD can be diagnosed in individuals living anywhere. The liver is the most common organ involved, with hepatic HD accounting for the majority of published cases. However, HD can affect multiple organs and tissues other than the liver, including the spleen, kidneys, lungs, heart, peritoneum, muscles, and brain. Knowledge of the route of spread, clinical findings at presentation, and possible complications involving each extrahepatic location can be useful for the radiologist when evaluating imaging findings in patients suspected of having HD. The ultrasonographic, computed tomographic, and magnetic resonance imaging findings of extrahepatic hydatid lesions frequently simulate those of hepatic HD, as long as rupture, bleeding, and/or superimposed bacterial infection has not occurred. Specific features of HD seen at different extrahepatic sites can help tailor the diagnosis. The differential diagnoses that can mimic HD at every nonhepatic location should be considered, as many of these entities are common, especially in nonendemic areas. © RSNA, 2017.

    Hidatid cysts of the spleen are a rare occurrence, the spleen being the third most common organ for the development of Echinococcus Granulosus. Splenic hydatid cysts are commonly part of multi-organ hydatid disease. Diagnosis is often established when investigating a splenomegaly or by chance during an unrelated consult. It can also be diagnosed after rupture, be it following trauma (the most common occurrence)or spontaneous. Splenic hydatid cyst rupture requires immediate action and is a life-threatening condition. It results, most often, in splenectomy. We present the case of a patient with multi-organ hydatid disease that presented with a ruptured splenic cyst and developed anaphylaxis. The case was resolved by splenectomy and recovered well. Celsius.

    Full Text Available Hydatid cyst and tuberculosis are common infectious diseases in our country. However, co-incidence of these two diseases is a rare case. This refers to spontaneous emergence of cyst hydatid and tuberculosis lesion in liver which is presented in this paper. Liver tuberculosis can be detected either as a component of miliary tuberculosis or isolated liver tuberculosis. Herein we report a case of 46 year-old male. He applied to the emergency due to the severe right-side pain which coupled with breathing and movement. This was reported to last for 10 days. Lesion compatible to cyst hydatid with a size of 151 x 144 x 128 mm was detected in the right lobe anterior in his abdomen ultrasonography. Echinococcus indirect hemagglutination test resulted in 1/640 positive. The patient had liver cystectomy by general surgery clinic. After microscopic examination of excision material, chronic granulomatous inflamation with caseous necrosis was detected in parenchyma to which cyst hydatid and lesion were attached. PPD result was 16 mm. The patient, whose lungs were normal, received antituberculosis treatment due to primary liver tuberculosis.

    Hydatid cyst, frequent in sheep raising countries, is a parasitic disease caused by a cestode, Echinococcus granulosus, and is spread to man by dog feces. A hydatid cyst, 7x8 cm in diameter, located on the dome of the liver of a 48 year old male patient was removed by thoracotomy. During the surgery, some hypertonic saline solution absorbed sponges were applied to the operation site. The same solution was used inside the cyst for scolocidal effect and the intraabdominal cavity was washed with the same solution. During the postoperative period, following extubation, a generalized convulsion developed. A serum sample of the patient was sent to the laboratory for testing of the serum sodium concentration. It was 185 mEq/L. The aim of this study was the consideration of hypernatremia and related neurologic signs depending upon the use of hypertonic saline solutions in hydatid cyst surgery for scolocidal effects. Because general anesthesia conceals neurological findings of hypernatremia, the serum sodium concentration should be followed carefully during surgery.

    Full Text Available Hydatid cyst disease, which is caused by echinococcusgranulosus still poses a serious problem in endemic areas.The disease frequently involves liver and lung. Otherorgan involvements are rare. In a 18-year old patient, bilaterallung, right ventricle of heart, liver and spleen involvementwere detected. With albendazole treatmentcyst in heart was completely disappeared, and liver cystwas found to be decreased in size. However, no declinein the number and size of cysts in lung was observed.Therefore, it was concluded that albendazole may not beeffective in pulmonary hydatid disease compared to otherorgans.Key words: Albendazole, hydatid cyst, multiorgan involvement

    Hydatidosis, caused by Echinococcus granulosus, is an endemic parasitic disease in Mediterranean countries. The most frequent anatomic locations are liver and lung. Intrathoracic rupture of hydatid cysts situated in the hepatic dome is a serious complication resulting in damage to the pleura, pulmonary parenchyma, and bronchi. From January 1984 to December 1997 we operated on 40 patients with intrathoracic rupture of a hepatic hydatid cyst. Chest roentgenograms showed a shadow of varying size at the base of the hemithorax. Hepatic and thoracic ultrasonography was performed in all cases. The diagnosis of intrathoracic rupture of a liver cyst was confirmed preoperatively in 30 of the 40 cases. Posterolateral thoracotomy was performed in all patients. This transthoracic approach allowed adhesiolysis and treatment of the pleural lesions, pulmonary lesions, and hepatic cyst. Treatment of the diaphragmatic gap is easily done. We performed 15 lobectomies, 10 wedge resections, 16 decortications, and in one patient simple drainage of a voluminous pleuropulmonary and hepatic purulent hydatic collection. The postoperative course was uneventful in 26 cases, but 14 patients had complications, from which 3 patients died. The therapeutic approach depends on ultrasonographic findings. We believe ultrasonography to be the best examination for assessing biliary, hepatic, diaphragmatic, and pleuropulmonary lesions. When an intrathoracic collection is present, thoracotomy must be performed and is sufficient if the biliary tract is safe. An abdominal approach is necessary when biliary duct drainage is required, and it may be sufficient in cases of direct rupture into the bronchi.

    Full Text Available Hydatid disease or hydatidosis is the most widespread zoonosis caused by Echinococcus granulosus. Liver and lungs are the most common sites. Bone involvement is rare and reported in 0.5%–4% with spinal involvement reported in 50% of these cases. We present a case of spinal hydatidosis in a 35-year-old male presenting with lower extremity weakness and numbness. Magnetic resonance imaging (MRI of the spine showed multiple cystic lesions at the T9–T11 level with involvement of the paraspinal muscles. The lesion was seen intraspinal, intradural, intramedullary, and epidural. Radiological impression was aneurysmal bone cyst. The patient underwent laminectomy, and the excised cysts showed characteristic features of hydatid cyst (HC on histopathology. The patient was started on antihelminthic therapy postoperatively. MRI is a diagnostic modality for HC, but the unusual location and absence of characteristic features can cause diagnostic difficulty. A high index of suspicion should be kept in patients residing in endemic areas and presenting with unusual cystic lesion of spine.

    Hydatid disease of bone is rare. It remains asymptomatic over a long period. It is usually detected after a pathological fracture or secondary infection or following the onset of compressive myelopathy in cases of vertebral lesions. Secondary infection of hydatid disease of bone could be difficult to treat. The authors present a case of chronic osteomyelitis of the proximal aspect of the left femur in a 37-year-old male patient secondary to hydatid disease of bone. It was treated by aggressive debridement, gentamycin beads, and bone graft to fill the defect. No recurrence of the hydatid lesion or infection was detected after 2 years. This case showed that in addition to aggressive debridement, gentamycin beads may be valuable in eradicating the infection in such a case.

    Echinococcus multilocularis, a small tapeworm in foxes, has gained considerable public attention owing to its wide distribution in central Europe. Conversely, diagnosis and treatment of the disease have been significantly improved in recent years. Consequently, the incidence among human populations has remained stable and relatively low for many decades. In southern Germany, France (Franche Comté and Doubs), Austria and Switzerland, the annual incidence ranges between 0.02 and 1.4 new cases per 100,000 inhabitants. The relevance of human AE refers to the high lethality of the untreated disease. Therapy consists predominantly of radical surgery followed by continuous, long-term chemotherapy using albendazole (or mebendazole). The action of chemotherapy alone is parasitostatic rather than parasitocidal; nevertheless, clinical improvement is observed in > 80 % of such cases, including a significantly improved prognosis. Diagnosis relies predominantly on imaging procedures and serology. Immunodiagnosis must be performed early, especially when a preclinical diagnosis is desired upon exposure to infection. Thus, in the framework of seroepidemiological studies, first-time evidence was obtained about the phenomenon of natural resistance in non-diseased persons. This raised the question of a potential immunogenetic predisposition in certain infected persons. E. granulosus (cystic hydatid disease) is practically non-existent as autochthonous infection in central Europe now. Most clinical cases of E. granulosus infections are thus observed among persons who have immigrated from - predominantly - the mediterranean basin.

    Objective: To evaluate the chest roentgenogram and CT characteristics of pulmonary hydatid disease (PHD). Material and methods: Forty-seven (27 male and 20 female, aged between 3 and 11 years) consecutive pediatric patients with surgically proven pulmonary hydatid cysts were enrolled for the study. Posteroanterior and lateral chest roentgenograms, CT of the chest, and laboratory findings (latex agglutination, Casoni skin test, and eosinophil count) were obtained from all of the patients. The radiological features (localization, internal architecture, number, diameter) were determined. Results: On CT examination, a total of 79 cysts were determined. On chest roentgenogram, 57 of 79 cysts were detected in all patients. Single cysts were seen in 33 patients, while multiple cysts were seen in 14. Median CT density of the cysts was 21 Hounsfield units (HU) (0-80). There were six giant cysts (>10 cm of cyst diameter). The crescent sign, water lily sign, and air-fluid level were seen in two, five and eight of the cysts, respectively. Apart from the classically described features of pulmonary hydatid cysts of the lung, a crescent-shaped rim of air at the lower end of the cyst (inverse crescent sign) was detected in three cysts. All of the liquid content of the cyst was expelled to the bronchial system (dry cyst sign) was observed in seven cysts. There were two infected cysts. Heavily calcified curvilinear cyst wall was present in one cyst. Pericystic reaction in the lung tissue was observed in five patients. Other features included pleural effusion (n=2), mediastinal shift (n=6) and atelectasis (n=7). Conclusions: Chest roentgenogram is helpful for diagnosis of intact cysts but, it is impossible to define entire morphology of the complicated cysts. CT imaging recognize certain details of the lesions and discover others that are not visible by conventional radiography. In conclusion, CT examination should be done to elucidate cystic nature of the lung mass and for accurate

    Full Text Available Hydatid disease is caused by the tapeworm Echinococcus. Genus Echinococcus has different species including Echinococcus vogeli, Echinococcus granulosus and Echinococcus multilucularis . Echinococcus granulosus is the most common cause of hydatid disease in humans. This disease occurs either through direct ingestion of parasite eggs from contact with infected dogs or indirectly from the ingestion of contaminated water or food. Infestation of hydatid disease in humans most commonly occurs in the liver (55-70%, followed by the lungs (18-35%. Bone hydatidosis however is very rare (3%. We present herein a case of hydatid cyst of the fibula, which is an uncommon site for the occurrence of this disease.

    Full Text Available Hydatid disease is the most common parasitic infection in the world, and is caused by the parasite Echinococcus granulosus. The most common site of this disease is the liver (75%, followed by the lungs, kidney, bones, and brain. Multiple abdominal organ and peritoneal involvement can also be seen in some cases. The dissemination of hydatid cyst disease can develop spontaneously or secondary to trauma or surgery. Here, we present the case of a 69-year-old man with multiple cyst hydatidosis, who underwent surgery for acute appendicitis approximately 20 years previously. Computed tomography of the abdomen shows the multiple active and inactive cystic lesions in the liver, spleen, right kidney, and mesentery. This patient required surgery several times, as well as medical treatment, after the rupture of a mesenteric hydatid cyst during the appendectomy. Combined anthelmintic treatment was recommended to the patient who refused further surgical treatment.

    Full Text Available Aim: Hydatid disease is a parasitic infection caused by Echinococcus granulosus. The lungs are the most common affected organs in children. Hydatid disease can appear with nonspecific symptoms such as cough, chest pain and hemoptysis. Radiological findings are important in the diagnosis of the disease. In this article, we report ten patients who presented with nonspecific pulmonary symptoms. Methods: We included 10 patients (age range: 4-15 years who attended our pediatrics outpatient clinic with the diagnosis of hydatid disease between May 2011 and May 2012. We analyzed the data on age, gender, primary complaint, clinical features, diameter and location of the cysts, and history of contact with animals. Hydatid cysts were diagnosed by imaging techniques and serologic tests. Results: The most common symptoms were coughing, chest pain, weakness, dyspnea, fever, and hemoptysis. In five patients, the cysts were located in the right lung; in four patients, the cysts were located in the left lung, and in the remaining patient, the cysts were bilateral. The diameters of the lung cysts were between 5 and 13 cm. Five of ten patients had both lung and liver cysts. Complications were observed in five patients. In eight patients, serologic tests results were positive. Five patients had a history of previous contact with animals. The patients were operated in the pediatric surgery unit. Conclusion: Hydatid disease is endemic in Turkey. Disease awareness and knowledge in children and their families is of great importance for the prevention of hydatid disease.

    A molecular PCR study using DNA from 21 hydatid cysts was performed to determine which strain type is responsible for human infection in Peru. The mitochondrial cytochrome c oxidase subunit 1 (CO1) gene was amplified in 20 out of 21 samples, revealing that all but 1 sample (19/20, 95%) belonged to the common sheep strain (G1). The remaining samples belonged to the camel strain (G6). The G1 genotype was most frequently found in human cases of cystic hydatid disease (CHD) in Peru. Local control measures should focus primarily on decreasing dog and sheep infection rather than intermediate reservoirs.

    Full Text Available PRESENTATION OF CASE The classical finding in hydatid disease caused by Echinococcus granulosus with liver or lung involvement is well known. However, diagnosing hydatid disease at unusual locations maybe challenging even in endemic areas causing diagnostic confusion as primary extrahepatic extrapulmonary hydatid cysts are rare and only a few sporadic cases have been reported. We present a case where a painless progressive cystic swelling was present in left inguinal region with positive cough impulse and irreducibility mimicking an inguinal hernia. CECT was done, which confirmed it to be multiple hydatid cysts. The patient underwent excision of the cysts with mesh repair and left inguinal orchiectomy as the cord structures couldn’t be separated from the cyst wall. Patient was discharged in satisfactory condition on oral antibiotics and albendazole. No recurrence noted on 6 months of follow up. So, a high suspicion for hydatid cyst should be kept in mind especially in endemic areas for any intra-abdominal swelling. The surgeon must keep in mind that this parasitosis can occur even in uncommon locations and therefore it should be regarded as a potentially systemic disease. In these cases, the diagnosis is challenging and can be achieved only through a complete interdisciplinary evaluation clinical, laboratory and radiological data.

    CT is the primary modality for the diagnosis. Two forms of cerebral hydatid cysts have been reported on the basis of CT appearances: unilocular and multilocular. Demonstration of the cyst wall is important for the diagnosis. MRI is superior to CT for demonstrating the cyst capsule and perifocal oedema. We retrospectively reveiwed the CT and MRI findings of 6 surgically proven cases of cerebral hydatid cyst and compared the two modalities on the basis of their demonstration of findings helpful in the diagnosis, such as the capsule and perifocal oedema. In 1 case CT showed the capsule. In 2 cases MRI showed a hypointense capsule around the cyst on T2-weighted images. While CT is the modality of choice, in clinical practice MRI is superior for demonstrating the cyst capsule, which is a helpful finding in the diagnosis and can be used in inconclusive cases.

    An attempt was made to estimate the prevalence of hydatid disease in nomadic pastoralists living in eastern Africa and to identify environmental, cultural and behavioural factors which may influence Echinococcus transmission. 18,565 nomadic pastoralists, from 12 different groups living in the vast, semi-desert regions of Kenya, Sudan, Ethiopia and Tanzania, were screened for hydatid cysts using a portable ultrasound scanner. High prevalences of hydatidosis were recorded among the north-western (5.6%) and north-eastern (2.1%) Turkana of north-west Kenya, the Toposa (3.2%) of southern Sudan, the Nyangatom (2.2%), Hamar (0.5%) and Boran (1.8%) of south-west Ethiopia and northern Kenya and the Maasai (1.0%) of Tanzania. Lower prevalences were recorded amongst the southern (0.3%) and lake dwelling (0.3%) Turkana and the Pokot (0.1%) of Kenya. The disease was not found amongst the Turkana, Samburu, Dassanetch, Gabbra, Somali or Rendille screened on the east side of Lake Turkana. The scanning surveys were well accepted by the people and provided evidence for the need to expand the present hydatid control programme in Turkana to cover the whole hyperendemic focus. Such a programme must contain an educational component for, although most groups recognized hydatid cysts, there was complete lack of knowledge concerning the parasite and its mode of transmission.

    Full Text Available Echinococcosis (CE is an infection which is caused by the larval stage of a tapeworm and is endemic in stockbreeding regions of developing countries. The kidney is the most commonly affected organ in the urinary tract. However, reports on renal hydatid disease are limited in the literature, and usually there are no specific clinical characteristics and promising operative methods. The purpose of this study is to assess the most appropriate surgical technique for the patient with urinary tract CE. We retrospectively analyzed thirty patients with renal hydatid cysts who received different surgical treatments in the urology department of the First Affiliated Hospital of Xinjiang Medical University from February 1985 to April 2010. Twenty patients were males and ten were females. The diagnostic accuracy was 74%, 87.5%, and 66.6% respectively by using of ultrasound, CT, and laboratory tests. Thirty patients were followed up for 1-15 years after surgery. One patient experienced a recurrence of renal CE. The ultrasound, CT, and immunological tests are an important means of diagnosis. The surgical treatment principle of renal hydatid should be based on residual renal function, hydatid cyst size, number, location, and surgical techniques to determine the surgical plan to retain the renal function.

The study was carried out to determine the clinical, radiological and pathological presentations of hydatid disease. Method This was a retrospective study of all hydatid disease cases reported in Department of Pathology, from August 1996 to July 2010. All the clinical, radiological and pathological data were collected and collated. Result A total of 51 cases of hydatidosis were studied. Patients presented with related symptoms in 47 cases, 92.16% with CI (84.78,99.54 and asymptomatic in 4 cases, 7.84% with CI (0.46, 15.22. Involvement of liver and lung was found in 35 cases (68.63% and 10 cases (19.61% respectively. Involvement of other organs like kidney, pelvis and broad ligament were seen in 6 of the cases. 29 cases, 56.86% with CI ( 43.2, 70.46 had solitary cyst while rest of the cases had multiloculated cyst. All cases had radiological correlation and histopathological confirmation. Conclusion Most cases presented with organ related vague symptoms, however it should be considered as a differential diagnosis especially in asymptomatic cases and cases with unusual sites. Imaging studies is useful in preoperative diagnosis and postoperative histopathology is confirmatory. A multi centric hospital based study will help to decrease the incidience.

  19. An analysis of possible mechanisms of unexpected death occurring in hydatid disease (echinococcosis).

    Science.gov (United States)

    Byard, Roger W

    2009-07-01

    Most cases of hydatid disease in human populations are due to Echinococcus granulosus. The hydatid life cycle involves passage between definitive hosts such as dogs and intermediate hosts such as sheep. Humans become accidental intermediate hosts following ingestion of food or water contaminated with eggs or by contact with infected dogs. Although hydatid disease may remain asymptomatic, occasional cases of sudden and unexpected death present to autopsy. Causes of rapid clinical decline involve a wide range of mechanisms including anaphylaxis (with or without cyst rupture), cardiac outflow obstruction or conduction tract disturbance, pulmonary and cerebral embolism, pericarditis, cardiac tamponade, myocardial ischemia, pulmonary hypertension, peritonitis, hollow organ perforation, intracerebral mass effect, obstructive hydrocephalus, seizures, cerebral ischemia/infarction, and pregnancy complications. The autopsy assessment of cases therefore requires careful examination of all organ systems for characteristic cystic lesions, as multiorgan involvement is common, with integration of findings so that possible mechanisms of death can be determined. Measurement of serum tryptase and specific IgE levels should be undertaken for possible anaphylaxis.

    Full Text Available Alveolar hydatid disease or alveolar echinococcosis is a disease of the parasite Echinococcus multilocularis that is potentially fatal if left untreated. It primarily involves the liver but can be disseminated to other organs like the lungs and the brain by hematogenous route. Multiorgan involvement and the aggressive appearance of lesions make alveolar hydatid disease easy to confuse with a metastatic malignancy. For this reason, histopathological confirmation is essential for definite diagnosis. We present the imaging features of this disease in two patients in order to emphasize that these lesions can be easily misdiagnosed as malignancies.

Materials and methods: Information of 217 HD patients including age, gender, address, organ involved, number and size of hydatid cysts, radiological and histopathological results were recorded from registry offices of four main Jordanian hospitals after receiving the required approvals. Results: The highest number of HD cases was recorded from the central provinces of Jordan; however, most cases were reported from Al-Mafraq governorate. Ultrasound (US was the most widely used diagnostic tool for HD. The liver was the most affected organ with HD and the age of most of the inspected patients was in the 3rd, 4th, and 5th decades. Single cyst per organ was recorded in 138 of the cases and large hydatid cysts (>5 cm were observed in 48 cases. Conclusions: Besides the awareness and control measures which are implemented by the Ministry of Health in Jordan to eradicate HD, results of the present study indicated that HD is still regarded as an important public health problem in the country. Imaging plays an essential role in the initial diagnosis of HD but not the classification of the disease. However, the definitive diagnosis is achieved after the surgical removal of hydatid cysts and the confirmation of the presence of the hydatid cyst layers is tested by histopathological techniques. Currently, surgery remains the only available treatment approach for HD in Jordan.

    Full Text Available Objectives: Hydatid disease is endemic and represents a major health problem in Yemen. The aim of this study is to determine the magnitude of the problem of hydatidosis in patients attending Public and Private Hospitals at Sana’a city, Yemen.Methods:66 patients with hydatid disease were identified during the period from August 2006 to February 2007. Complete medical history for all CE patients were collected and analyzed.Results: Among the 66 CE patients, 67% were females and 33% males. Liver was the most common involved organ. Single cyst was more frequently detected than multiple cysts and approximately 94% of the cysts were ≥5 cm. Moreover, Public hospitals were the main source of patients with CE disease.Conclusion: Hydatidosis is still an endemic disease and an important health problem in Yemen which needs to be studied further. Therefore, accurate information on the distribution of the disease is the first step for the control and prevention of the disease. Moreover, it is crucial to investigate the role of different intermediate hosts and genotypes of E. granulosus in humans and animals.

    Echinococcosis is a zoonotic infection with a worldwide distribution, and is still an important health problem in many areas of the world, including the Mediterranean basin. At present the epidemiological situation is unclear in certain regions of Spain. The aim of this study was to update the epidemiological situation in Extremadura through an analysis of hospitalised patients in the public health system diagnosed with hydatid disease. A longitudinal retrospective study was conducted between 2003 and 2012 on hospitalised patients with a diagnosis of hydatidosis (ICD 122.0-122.9) in hospitals of the public health service of Extremadura. During the period of study, 876 patients were diagnosed with hydatid disease. Of these 536 (61%) of cases were male, with a mean age of 65.53±17.8 years. More importantly, 19 (2.2%) of patients were 19 years old, with 17 cases between 2003-2007 versus 2 cases between 2008-2012 (OR=7.83; 95%CI: 1.79-34.11; P=.001). A total of 141 (16.0%) were younger than 45 years. The primary diagnosis was most frequently reported in the younger population 70 years (P<.05). The incidence rate of hydatid disease obtained from Hospital Discharge Records (HDRs) was significantly higher compared to the incidence that was declared in the Notifiable Disease System of Extremadura (8.02 cases per 10(5) person-years vs. 1.88 cases per 10(5) person-years [P<.05]). In Extremadura hydatid disease is still frequent. With a clear decrease in the number of paediatric cases. The number of cases obtained from HDRs regarding Notification System Diseases Extremadura suggests the need for modifications to improve surveillance and control of hydatid disease.

    To present MRI findings in two cases of cerebral hydatid disease with an emphasis on diffusion-weighted imaging (DWI) findings of Echinococcus granulosus (EG) versus Echinococcus alveolaris (EA). EG lesions were isointense with cerebrospinal fluid in all sequences including DWI. On DWI, EA lesions remained hypointense on b = 1000 s/mm2 diffusion-weighted images. Apparent diffusion coefficient (ADC) values of EG and EA lesions were completely different from each other, 2.88 {+-} 0.24 x 10{sup -3} s/mm{sup 2} and 1.33 {+-} 0.15 x 10{sup -3} s/mm{sup 2}, respectively. The ADC values could not be used to discriminate from other differential diagnoses.

    Two patients with thoracic manifestations of hydatid disease (HD) are discussed; one patient had recurrent HD of the chest wall and the other, intrapulmonary HD after rupture and intrathoracic extension of an infradiaphragmatic cyst. At magnetic resonance (MR) imaging the manifestations of HD in the thorax are similar to previously reported MR findings in HD in the liver. The presence of a low signal intensity rim on T2 weighted images representing the cyst wall was confirmed. On T1 weighted images cysts with heterogeneous low and intermediate signal intensity contents and a relatively high signal intensity wall were seen. ''Folded parasitic membranes'' previously not described on MR were noted. Daughter cysts may have a low or high signal intensity depending on contents. Reactive changes in the lung may be quite marked compared with the liver, due to reaction to the parasite or simply because the lung is more easily compressed leading to secondary atelectasis.

    To evaluate the various tactics and approaches in the surgical treatment of bilateral pulmonary hydatidosis (BPH). Between 1969 and 2000, a total of 127 BPH patients underwent surgery. The operative techniques of choice were parenchyma-preserved methods. Up to 1988, two-stage operations via thoracotomies were performed on 30 patients. One-stage operations with successive thoracotomies were carried out on two patients. Since 1988, only four patients underwent two-stage operations. One-stage surgery was carried out on 91 patients: 82 via median sternotomy (MS), one via clamshell incision, four through successive thoracotomies and three through video-assisted thoracic surgery (VATS) and mini-thoracotomies. One-stage bilateral lower lobectomies via MS were performed on one patient. In 11 cases, the concomitant dome localized liver cysts were extirpated via right phrenotomy during MS. Sterno-laparotomy was performed on 11 patients: for associated hepatic (seven), and hepatic and spleen cystectomies (four). In eight cases, abdominal echinococcosis was operated on a second stage, and in one case, a complicated hepatic cyst was extirpated on a first stage. No intraoperative deaths occurred. The postoperative mortality rate was 0.78%; one patient died of pulmonary embolism. No fatal complications have appeared in eight cases (skin suppuration, residual pleural cavity and atelectasis). Adult respiratory distress syndrome was successfully treated in one case after MS. The long-term postoperative results are considered very good, with no recurrences observed. One-stage surgery is superior to a classic two-stage approach as it decreases the morbidity, hospital stay and costs. MS is an excellent approach, but in some cases, VATS mini-thoracotomies could be indicated.

    Thirty patients with thoracic hydatidosis (Echinococcus granulosus) were studied. The hydatid cysts were located in the lung parenchyma (70%), mediastinum (6.7%), inside the heart (10%), the pleurae (10%) and the chest wall (3.3%). Complications of thoracic hydatid cysts, such as rupture, infection, pleural involvement, spread and calcifications are presented. Computed tomography (CT) without and/or with contrast enhancement was performed in all patients (30). Findings from conventional chest radiographs were compared with CT and confirmed by pathology (30). In 10 cases (33.3%), magnetic resonance imaging was also performed. The diagnostic spectrum of hydatid cysts, including variations and developmental stages, is presented in this pictorial essay. (orig.)

    In France, in North of Alps and South of Jura, around the Swiss town of Geneva, the cestode E. multilocularis was found in three out of 81 domestic cats necropsied given by veterinarians. Morphological and morphometric features established the identity of this species. In an endemic area of alveolar hydatid disease, the prevalence of E. multilocularis in the domestic cat confirms that it is a risk factor for human beings and mainly for veterinarians.

    Full Text Available BACKGROUND Hydatid Disease (HD is a zoonotic disease caused by the larvae of Echinococcosis granulosus, now become a rare clinical entity in teaching medical college hospitals. This is due to the public education about the disease, mode of spread and treatment available. The aim of the study is to review the epidemiology, clinical presentation, diagnostic methods available, organs affected and treatment available in the tertiary hospitals and outcome. MATERIALS AND METHODS Data Collection- Patients with upper right abdominal pain with radiological and ultrasound findings are included in the study. About twenty patients are taken for this study. Medical managements, surgical procedure done and outcomes are recorded, tabulated and analysed. Research Design- Prospective Study, Research Setting- KAPV Govt. Medical College and Mahatma Gandhi Memorial Govt. Hospital, Trichy, Tamilnadu. Duration- 7 yrs. (2009 to 2016 Sample Size- Twenty. Inclusion CriteriaPatients between 12 to 70 years of age of both sexes. Patient having right upper abdomen or epigastric pain with positive radiological and ultrasound findings. Patient willing to participate in the study. Exclusion Criteria- Patients more than 70 years not willing to participate in the study patients absconded in between the management. RESULTS Liver is a commonest solid organ affected by the hydatid disease. Most of the diagnosis are made accidentally when the patients are investigated for some other diseases. The commonest clinical presentation is right abdominal or epigastric pain with hepatomegaly. The average age group is 45 years. X-ray abdomen, ultrasound abdomen are the most useful investigations.

    Full Text Available BACKGROUND: Cystic hydatid disease (CHD is a global parasitic zoonosis caused by the dog tapeworm, Echinococcus granulosus. The disease is hyperendemic in western China because of poor economic development; limited community knowledge of CHD; widespread, small-scale household animal production; home killing of livestock; and the feeding of dogs with uncooked offal. METHODOLOGY/PRINCIPAL FINDINGS: A control program focusing on monthly praziquantel (PZQ treatment of all registered dogs and culling unwanted and stray dogs has been designed to control CHD in hyperendemic areas in China. A pilot field control project in two counties (Hutubi and Wensu in Xinjiang, China showed that after 4 years of treatment, the prevalence of dogs with E. granulosus was reduced from 14.7% and 18.6%, respectively, to 0%, and this caused a 90%-100% decrease of CHD in sheep born after commencement of the control program. CONCLUSIONS/SIGNIFICANCE: The strategy aimed at preventing eggs being released from dogs into the environment by treating animals before adult tapeworms are patent can decrease E. granulosus transmission and considerably reduce hyperendemic CHD. Monthly treatment of dogs with PZQ and culling unwanted and stray dogs have been shown to be an efficient, highly cost-effective and practicable measure for implementation in rural communities. As a result, the Chinese Ministry of Health has launched an extensive CHD control program in 117 counties in western China using this control strategy.

    Echinococcosis, also known as hydatid disease or hydatidosis, is a zoonotic illness caused by the larval form of Echinococcus spp. It is highly prevalent in areas where the parasite is endemic such as the Mediterranean region. However, occurrence of echinococcosis and cancer together is rare. We treated and followed approximately 1200 patients with different hematologic neoplastic diseases between 1985 and 2003, and only one of these individuals had concomitant acute leukemia and liver hydatidosis. This report describes the case of a 19-year-old man who had both primary refractoriness of acute leukemia (AML-M4) and liver hydatidosis. Management is discussed. The patient had cystic echinococcosis (CE) of the liver that was classified as CE1 according to the system established by the World Health Organization's Informal Working Group on Echinococcosis. The patient underwent 3 months of treatment with agents that targeted the leukemia (daunorubicin, idarubicin, cytarabine, fludarabine) and its complications (amphotericin B, amphotericin B lipid complex, liposomal amphotericin B). Throughout this period, the size and the contents of the cyst did not change, Echinococcus titers remained unchanged, and the cyst classification remained CE1.

    A monoclonal antibody (mAb) designated as EG 02 154/12, specific for the major antigen (antigen 5) of Echinococcus granulosus was produced, and used to study the binding sites recognized by anti-antigen 5 antibodies from patients with hydatid disease. The nature of the target epitope was partially characterized. The antibody reactivity was analyzed towards sheep hydatid fluid antigens (SHF Ag) using ELISA, immunoelectrophoresis (IEP), Western blotting (WB), and immunoprecipitation (IP). In IEP, EG 02 154/12 mAb gave a single precipitin of Ag 5. The mAb and human hydatid patient sera recognized a major antigen of 64 kDa, in SHF Ag analyzed in non-reducing conditions. Both types of antibodies revealed two components of 37 and 22 kDa in reducing conditions. Deglycosylation and delipidation of SHF Ag did not affect the mAb binding. These results, together with the observation of mAb binding to in vitro translation products from protoscoleces messenger RNA, suggest the protein nature of the epitope recognized on the antigen 5. Using competitive antibody radioimmunoassay (CRIA), a competition between this mAb and hydatid patient sera, for the same epitope or closely related sites on antigen 5, was observed. No such competition was detected with the sera from other helminthiasis. The sensitivity and specificity of CRIA was compared to that of ELISA and CRIA found to be an improved diagnostic test for hydatid disease.

    Although Serbia is recognized as an endemic country for echinococcosis, no information about precise incidence in humans has been available. The aim of this study was to investigate the skeletal manifestations of hydatid disease in Serbia. This retrospective study was conducted by reviewing the medical database of Institute for Pathology (Faculty of Medicine in Belgrade), a reference institution for bone pathology in Serbia. We reported a total of 41 patients with bone cystic echinococcosis (CE) during the study period. The mean age of 41 patients was 40.9±18.8 years. In 39% of patients, the fracture line was the only visible radiological sign, followed by cyst and tumefaction. The spine was the most commonly involved skeletal site (55.8%), followed by the femur (18.6%), pelvis (13.9%), humerus (7.0%), rib (2.3%), and tibia (2.3%). Pain was the symptom in 41.5% of patients, while some patients demonstrated complications such as paraplegia (22.0%), pathologic fracture (48.8%), and scoliosis (9.8%). The pathological fracture most frequently affected the spine (75.0%) followed by the femur (20.0%) and tibia (5.0%). However, 19.5% of patients didn't develop any complication or symptom. In this study, we showed that bone CE is not uncommon in Serbian population. As reported in the literature, therapy of bone CE is controversial and its results are poor. In order to improve the therapy outcome, early diagnosis, before symptoms and complications occur, can be contributive.

    Full Text Available Background: Vast majority of complaints and physical examination findings of hydatid disease are common in emergency room patients. Different emergency presentations of hydatid cyst disease and their treatment are evaluated. We studied preoperative laboratory findings of these patients to identify any parameters to predict hydatid cyst-biliary system communication.Methods: We reviewed the files of patients who underwent emergency surgery due to liver hydatid cysts and related conditions between March 2010 and March 2014 in Ankara Numune Research and Training Hospital, Turkey, retrospectively. Patients were grouped, regarding to the presence of biliary system involvement.Results: Twelve patients (9 males, 3 females were included. We identified two groups. Biliary system involved group (n=9 had significantly higher pre-operative gamma glutamine transferase and alkaline phosphatase levels (P=0.036. No significant difference was noted regarding other pre-operative laboratory findings. Mortality rate was 17%.Conclusion: Medical literature lacks sufficient information about hydatid disease related non-traumatic emergency surgeries. Preoperative elevated gamma glutamyl transferase and alkaline phosphatase levels may be questioned as a warning about cyst-biliary communication in hydatid cyst patients with abdominal pain in the emergency room. Future studies with larger sample sizes are needed. In addition, prolongation of the time before diagnosis in these patients may result in life threatening complications.

    Full Text Available Echinococcus granulosus is considered the major cause of humanhydatid cysts. Usually the duration of cyst formation is 10-20 years. This period shortens significantly upon rupture of aprimary cyst. The literature describes low incidence of primaryinvolvement of ovary as a site of hydatid cyst formation. Ourcase is the first report on ovarian hydatid cyst in Iran. A 60-year-old woman was presented with abdominal pain in the leftlower quadrant area. Paraclinical data were suggestive of neoplasiaand preoperative diagnosis was ovarian tumor. Duringlaparotomy, multiple cysts resembling hydatid cysts were observedin the left ovary. Pathological examination confirmed thediagnosis of hydatid cyst. Although there is a small possibilityof secondary ovarian echinococcal disease, it is more probablefor this case to be primary infection, as the patient had developedovarian hydatid cysts 15 years after hepatic involvementand recurrence after 30 months is very uncommon.

    We report a rare case of a 30-year-old breastfeeding woman who presented to our surgical outpatient department with complaints of a gradually enlarging lump in her left breast for the last 2 months. She also complained of difficulty in breastfeeding for 1 week. On examination, the right breast was normal but there was a 4 cm × 4 cm retroareolar soft lump in her left breast. Examination of the bilateral axilla was normal. A provisional diagnosis of galactocele was made and the patient was subjected to ultrasonic mammography and fine needle aspiration cytology (FNAC). Ultrasonic mammography of the left breast showed a heterogeneous, hypoechoic lesion with thick septations and internal echoes suggestive of a complex cystic lesion, leading to a differential diagnosis of either hydatid cyst or breast abscess. On FNAC, the aspirate was not milky and cytological examination was performed, which revealed hydatid scolices, hooklets, foamy macrophages and granular debris, leading to the final diagnosis of hydatid cyst of the breast. The patient was investigated further but there were no cysts at any other site. Chemotherapy with albendazole was started and surgery was performed after 1 month. Histopathology further confirmed the diagnosis. Owing to the rarity of presentation, this case is being reported here.

    Full Text Available Echinococcosis in humans occurs as a result of infection by the larval stages of taenid cestodes of the genus Echinococcus. Most of the intracranial hydatids develop in brain parenchyma. Hydatid cyst within the cerebral ventricle is quite unusual. Literature review showed few case reports of childhood as well as adult intraventricular hydatid cysts. None of these cases presented for the first time with features of ruptured intraventricular cyst. This is a very rare presentation of a common disease. The possibility of infestation with E. granulosus should be included in the differential diagnosis of raised intracranial tension in patients reporting from endemic areas, because the prognosis following surgical intervention is excellent, especially in the pediatric age group.

    Hydatid disease in humans is caused by Echinococcus granulosus. It most commonly involves the liver and, to a lesser extent, the lungs and spleen; however, it is known to involve other areas, too. Involvement of bone by hydatid cyst is rare. Here, we describe the case of a 37-year-old woman who presented with pain in the left groin and swelling in the left thigh. The radiological imaging showed a fracture of the femoral neck and cysts in the shaft of the femur. Diagnosis of hydatid cyst was confirmed on the basis of histopathology of biopsy specimens. The patient recovered after surgical excision of the cyst. This case illustrates the various sites and presentations of hydatid cyst disease, and the need to investigate for it if cystic bony lesions are encountered especially in endemic regions, as a delay in diagnosis can lead to long-term morbidity and even death. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    Hydatid disease is a zoonosis caused by Echinococcus granulosus. It is a progressive disease with serious morbidity risks. Sacral hydatid disease is very uncommon, accounting for meningocele. A posterior approach with laminectomy from L-5 to S-3 was performed. Three lesions with classic features of a hydatid cyst were observed and removed. The diagnosis of hydatid cyst was confirmed histopathologically. Antihelmintic treatment with albendazole (15 mg/kg/day) was included in the postoperative treatment. The patient's condition improved after surgery, and he recovered normal mobility. The unusual site and presentation of hydatid disease in this patient clearly supports the consideration of spinal hydatid disease in the differential diagnosis for any mass in the body, especially in endemic areas.

    Full Text Available Hydatid disease is caused by Echinococcus granulosus. In this study, we aimed to investigate the benefit of monitoring cases with hydatid cyst by means of immune components in patients in a long-term follow-up after surgery. Eighty-four preoperative and postoperative serum samples from 14 cases undergoing surgery for hydatid disease were evaluated in terms of immune parameters, such as total and specific IgE, IgG, IgM, IgA and complement. Total and specific IgE were determined by ELISA. Specific IgG levels were measured by indirect hemaglutination.Total IgG, IgM, IgA and complement (C3 and C4 were detected by nephelometry. Imaging studies were also carried out during the follow-up. In none of the patients hydatid cysts were detected during the follow-up. Total IgE levels in the sera of the patients decreased to normal six months after surgery. Although specific IgE against echinococcal antigens decreased one year after operation, levels were still significantly high. There were no changes in the levels of anti-Echinococcus IgG and total IgG in follow-up period. Additionally, other parameters, such as IgA, IgM, C3 and C4, were not affected.

    Hydatidosis is an endemic affection in Morocco. Cerebral echinococcosis is a relatively rare entity accounting for only 1-2% of all hydatid cysts in humans. hydatid cyst of the posterior fossa is a very uncommon site for the disease. We report the case of a 12 year-old child admitted for high intracranial pressure. Brain CT scan showed a posterior fossa cyst without enhancement after contrast medium injection. Operative finding revealed a hydatid cyst. The histological examination of the tissue sample confirmed the diagnosis. The patient was given albendazole post operatively.

    Full Text Available "Hydatid" is a Greek word which means "a drop of water." Hydatid cysts occur in hydatid disease or echinococcosis, which is one of the most geographically prevalent zoonosis. This zoonotic infection in humans is mainly caused by infection by the larval stage of the dog tapeworm Echinococcus granulosus. This tapeworm infestation is widespread in sheep, goats, cattle, and dogs. This chronic disease is present worldwide among herding populations who live in close proximity to dogs and herd animals. It is a serious and potentially fatal condition and symptoms may occur a long time after the early infection. The most frequently affected organs are liver, lungs, followed by bones and brain, and extremely unusual occurrence has been found in the oral cavity, which was noticed in the present case. So hereby, we reveal a very rare case of intraoral hydatid cyst in a 20-year-old female patient.

    Full Text Available Cardiac hydatidosis is rare presentation of body hydatidosis. Incidence of cardiac involvements range from 5% to 5% of patients with hydatid disease. Most common site of hydatid cyst in heart is interventricular septum and left ventricular free wall. Right ventricular free wall involvement by cyst that ruptured to pericardial cavity is very rare presentation of hydatid cyst. Cardiac involvement may have serious consequences such as rupture to blood steam or pericardial cavity. Both the disease and its surgical treatment carry a high complication rate, including rupture leading to cardiac tamponade, anaphylaxis and also death. In the present report, a 43-year-old man with constrictive pericarditis secondary to a pericardial hydatid cyst is described.

    Full Text Available Cardiac hydatid cyst is rare and usually occurs in the setting of disseminated disease. Herein, we reported a case of isolated right atrial hydatid cyst misdiagnosed clinically as a tumor. A 65-year-old woman diagnosed as having large right atrial mass suspected of malignancy underwent resection of the cardiac mass. Histopathological examination showed laminated membrane and protoscolices of Echinococcus Granulosus. However, all other work-ups failed to document systemic diseases. Therefore, isolated cardiac hydatid cyst was diagnosed. Hydatid cysts should be considered in differential diagnosis of any cardiac mass, especially in endemic areas.

    Full Text Available Objective: To investigate the lethal effect of microwave radiation on protoscolices of hydatid cyst. Methods: The protoscolices were divided in two separate groups. The first group received continuous irradiation while the second group received repetitive irradiation. According to the exposure time, the first and the second groups were divided into 8 subgroups. Non-treated protoscolices were considered as the control in each experiment. The protoscolex mortality rate was calculated, and changes in temperature difference in protoscolex suspension before and after the irradiation and the mortality rate with the increase of exposure time were recorded. Results: The results showed that microwave was able to increase the mortality rate of protoscolices in hydatid cyst. The mortality rate from 20% in 20 s of continuous exposure was increased to 100% in 50 s. Also, the differences between the mortality rates in subgroups of the first and the second groups and the control were significant (P < 0.001. Although the effect of temperature change in repetitive irradiation was not significant, non-thermal repetitive irradiation effects were obviously stronger than the thermal continuous irradiation effects. Conclusions: It seems that, microwaves especially in the repetitive mode, may be used as a supplementary measure for both treatment and prevention of hydatidosis.

    Full Text Available Hydatid cyst disease of lungs may not be symptomatic. It may present as spontaneous rupture in pleura or a bronchus. During spontaneous breathing, cyst content of endobronchially ruptured pulmonary hydatid cyst is mostly evacuated by coughing. However, during positive pressure ventilation such extruded fragments may lodge into smaller airway leading to an airway catastrophe. We present such accidental endobronchial rupture of pulmonary hydatid cyst during surgery, its prompt detection, and management by rigid bronchoscopy.

    There is hearsay that prevalence of hydatid disease in Khammam and Nalgonda districts of Andhra Pradesh is high. We report here a preliminary study conducted to determine the magnitude of the problem of hydatid disease and the morbidity associated with it in patients attending MGH, KMM, A.P. (rural hospital). Eleven cases were identified during the period from November 2005 to May 2006 (seven months). Pain in abdomen, mass per abdomen, loss of appetite, pregnancy complicated by cystic echinococcosis (CE), and jaundice were the main clinical symptoms and signs. Ultrasonography, detection and removal of the cysts on the operation table, microscopic examination of the aspirated hydatid fluid were confirmatory. Ziehl-Neelsen stain of the aspirated fluid revealed acid-fast scolices. Interrogation of the patients and their family members (50) revealed that there was a total lack of knowledge of dog-tapeworm-caused infection in humans. They knew 'rabies' as the only disease man gets from dogs, and tapeworms are from pork and beef.

    Hydatid disease is a parasitic infestation caused by the larval stage of the tapeworm genus Echinococcus. In man, the two main forms are due to E. granulosus and, lee frequently, E. multilocularis. Man becomes infected by contact with a definite host or by consuming contaminated water or vegetable. Hydatid disease is prevalent throughout much of the world such as the middle east, eastern Australia, central Europe, south America, Alaska, but it is very rare in Korea. We experienced one case of pulmonary hydatid disease. Chest films revealed ovoid mass in the left lower lobe and seen as unilocular water-density cystic lesion on chest CT, which was removed surgically, and then the pathology confirmed the diagnosis.

    Full Text Available Hydatid disease in both chambers of the heart is very rare. Mobile right atrial and right ventricular hydatid cysts were diagnosed incidentally in the etiologic work up for a transient ischemic attack in a 77-year-old man with a history of a hepatic hydatid cyst operation. Transthoracic echocardiography was very successful in the diagnosis of both hydatid cysts. Transesophagial echocardiography and computed tomography confirmed the diagnosis. Both right atrial and right ventricular hydatid cysts were removed under cardiopulmonary bypass to prevent morbidities and potentially fatal complications.

    Chest wall, mediastinal, pericardial, myocardial, lobar fissure and pleural locations of the hydatid cysts are referred to be intrathoracic extrapulmonary cysts. In this report a 20-year-old male patient had a liver dome cyst, which was opened into the diaphragm and caused diaphragmatic hydatid cysts. The scoleces have probably been transported by diaphragmatic lymphatics into the subpleural location and then hydatid disease has been disseminated via parasternal lymph nodes anteriorly and intercostal lymph nodes posteriorly towards cupola of the thorax. With regard to this localization, we propose a novel terminology as 'intrathoracic extrapleural hydatid cyst' and we hypothesize a novel dissemination theory for the hydatid cysts via diaphragmatic lymphatic drainage.

    Hydatid disease (HD) is an ancient disease and even was known to Hippocrates. This disease involves all human parts and most common affected organs are liver and lungs. Incidence of unusual site is about 8-10%. The clinical picture depends upon the involved organs, its effects on adjacent structures, complications due to secondary infection, rupture, and anaphylaxis caused by hydatid cysts. The aim of this study was to find out incidence of unusual location of hydatid cyst in the human body. A retrospective study of HD was carried in a medical college between July 2007 and June 2012. A total 79 cases of HD were treated during this period. Information on clinical presentation and management were reviewed, and results presented as summary statistics. Sixty one cases were of liver HD, and 11 were with hydatid lung disease. Fifty cases were with right lobe involvement, and rest 11 were with both lobe involvement. Out of 11 lung hydatid only one case was with bilateral lung involvement. Only eight cases of HD of uncommon locations and presentations were encountered during this period. First case presented with left hypochondriac mass as splenic HD, second with pelvic HD along with obstructive uropathy, third with non-functioning right kidney with bilateral psoas muscles HD, fourth with HD involving mesentery, fifth with pelvic pain due to right ovary HD, sixth with simultaneous involvement of the liver and right subdiaphragmatic region, seventh with HD of right inguinal region, and eighth with hydatid cyst of the left kidney. Even though, there was no mortality found in these patients, there was high morbidity. We conclude that Echinococcus granulosus can affect any organ in the body from head to toe, and a high suspicion of this disease is justified in endemic regions. Moreover, medical treatment should be given in the pre-operative period as well as in the post-operative period for 4-6 weeks.

    Full Text Available Abstract Introduction Echinococcosis, or hydatid disease, is endemic in some regions of the world, and has been a common pathology of surgical wards in Kosovo. Primary hydatid cyst of the gallbladder is an unusual and very rare localization of hydatid disease. So far, only five cases that fulfill the criteria of primary gallbladder hydatidosis have been published in the English medical literature. Case presentation We report a case of a 39-year-old Kosovan Albanian woman referred to the Abdominal Surgery Division of the University Clinical Center of Kosovo for "a calcified hydatid cyst of the liver with gallbladder involvement". Her history was significant for chronic right upper quadrant pain, characterized as intermittently colicky pain, accompanied by nausea. The patient underwent right subcostal laparotomy. Intra-operatively, a calcified primary hydatid cyst of the gallbladder was found. Its pericyst was tightly attached to the liver. Complete pericystectomy with cholecystectomy followed. The histopathology confirmed the presence of calcified hydatid cyst of the gallbladder, and that the cyst had developed entirely extra-mucosally. Five year follow-up showed no recurrence of disease. Conclusion Primary hydatid cyst of the gallbladder is a very rare clinical entity. Accurate preoperative diagnostic localization is not always easy, particularly in centers with limited diagnostic tools.

    Full Text Available Hydatid disease in tropical areas poses a serious diagnostic problem due to the high frequence of cross-reactivity with other endemic helminthic infections. The enzyme-linked-immunosorbent assay (ELISA and the double diffusion arc 5 showed respectively a sensitivity of 73% and 57% and a specificity of 84-95% and 100%. However, the specificity of ELISA was greatly increased by using ovine serum and phosphorylcholine in the diluent buffer. The hydatic antigen obtained from ovine cyst fluid showed three main protein bands of 64,58 and 30 KDa using SDS PAGE and immunoblotting. Sera from patients with onchocerciasis, cysticercosis, toxocariasis and Strongyloides infection cross-reacted with the 64 and 58 KDa bands by immunoblotting. However, none of the analyzed sera recognized the 30 KDa band, that seems to be specific in this assay. The immunoblotting showed a sensitivity of 80% and a specificity of 100% when used to recognize the 30 KDa band.La Hidatidosis en áreas tropicales representa un serio problema diagnóstico por la alta frecuencia de reactividad cruzada con otras infecciones helmínticas.

    Full Text Available Introduction. Hydatid disease is a disease caused by the cestode Echinococcus. Echinococcus granulosus is the most common Echinococcus species affecting human. It may affect any organ and tissue in the body, most in the liver and lung. Disease is endemic in some regions of the world, and is common in Iran. Primary hydatid cyst of the axillary region is an unusual and rare localization of hydatid disease. So far, only sixteen cases have been published in the all medical literature. Case Report. Herein, we present a 33-year-old woman because of a mass in the axillary region of four months duration. Axillary ultrasonography showed a thick wall cystic lesion. No abnormality was found in mammographic examination of either breast, or in abdominal ultrasonography and chest X-ray. The mass was excised for pathological examination that showed a typical laminated membrane of hydatid cyst. Postoperative IgG- ELISA serology in this case was negative. Based on pathology an axillary hydatid cyst was diagnosed. Conclusion. Hydatid cyst should be considered in endemic areas in patients presenting with a soft tissue mass in the axillary region.

    Full Text Available Introduction. Hydatid disease (HD is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR technique is another nonsurgical option.

    Hydatid disease of the liver remains endemic in the world and is an imported disease in The Netherlands. The aim of this study was to evaluate the treatment and outcome of surgically treated patients for hydatid disease in a single center in The Netherlands. This retrospective study included 112 consecutive patients surgically treated for hydatid disease between 1981 and 2007. The primary outcome was relapse of the disease. Secondary outcomes were infections, complications, reoperations, length of hospital stay, and mortality. In all cases, echinococcosis was diagnosed by computed tomography or ultrasonography (US). Serology (enzyme-linked immunosorbent assay, immunofluorescence) confirmed the diagnosis in 92.9%. Most of the cysts were seen only in the liver (73.5%). All cysts were operated on with the frozen seal technique. Relapse of disease was seen in 9 (8.0%) cases. Five (4.5%) required surgical treatment at a later stage. Twenty (17.9%) complications were recorded. Four (3.6%) needed radiological drainage and three (2.7%) a reoperation. Follow-up was performed with US and/or serology at a mean of 24 months (range 0.5-300 months). All but one complication were seen in the liver-operated group, this proved not to be of statistical significance (P = 0.477). Patients with complications stayed significantly longer in hospital than did the patients without complications (P seal method of surgery for hydatid disease is safe and effective. Future studies are needed to prove its position in the treatment of hydatid disease as new developments show promising results.

    Patients with hydatid cysts (336) were studied at Riyadh Military Hospital, Saudi Arabia, between February 1985-June 2008, out of which 254 patients underwent non-surgical management and 82 patients had surgery. Drug therapy was administered to 194 of 254 patients: albendazole was administered in 65 patients; (albendazole+praziquantel) in 129 patients; 12 patients had endoscopic management; 48 patients had Percutaneous-Aspiration-Injection-Reaspiration (PAIR) and 82 patients had surgery. Out of 65 patients, 34 had completed albendazole of which 12 (35%), had cyst disappearance, 8 patients had partial cyst reduction, 12 had no response and were referred for combined therapy or PAIR; 66 patients with cysts in different organs completed the study using albendazole+praziquantel, in 50% of these cysts had disappeared and 16 (24%) observed reduction of cysts; 48 patients underwent PAIR, of which in 36 cysts (66.66%) disappeared; 82 patients had surgery and 20% had post-surgical complications. A great advance recently has happened in the non-surgical management of hydatid cysts including medical, PAIR and endoscopic management, which has led to a significant reduction in the need for surgical intervention.

    Full Text Available Background Hydatid disease of the liver is endemic in cattle areas of the world. A variety of treatment options is available. The common treatment options are medical therapy, surgery and puncture-aspiration-injection-reaspiration (PAIR therapy. Aims To evaluate the clinical outcomes and effectiveness of PAIR therapy in the treatment of liver hydatid disease using 3 per cent hydrogen peroxide (HP as a scolicidal agent. Methods Between October 2012 and October 2015, seventy hydatid cysts in 52 patients were treated by PAIR procedure using three per cent HP as a scolicidal agent. Pre-procedural clinical, radiological and laboratory characteristics and postprocedural morbidity, mortality and length of hospital stay were recorded. Results We performed PAIR of 70 hydatid cysts in 52 patients with a success rate of 95 per cent without any mortality. The mean length of hospital stay was three days (ranges 1–8. In our series, minor complications occurred in six patients and major complications in five patients. The follow-up period ranged from 12–18 months, with a mean of 15.3 months. Three patients developed recurrence. Conclusion PAIR therapy is a minimally invasive procedure for Gharbi type I-III hepatic hydatid cysts. It is a relatively safe procedure with a significant reduction in the duration of hospital stay. We believed that HP by itself plays a role in influencing the results and the outcomes of PAIR.

Material and methods: description of patients assessed in the Department of Surgery for hepatic hydatid disease. Results: in a group of 70 patients with HHD, 27 patients were not treated surgically (mean age: 72.7 years [range: 47-97], 14 women [51.8%]. The number of cysts presented by these patients was 33, with 1.22 cyst/patient (range: 1-4. The cyst size was 5.5 cm (range: 2.1-12.5 cm. The cysts, according to the WHO classification, were CE1: 3 patients, CE3B: 5 patients, CE4: 10 patients and CE5: 9 patients. The form of presentation was: symptomatic in 9 patients, although only 6 were attributable to HHD (22% and asymptomatic in 18 patients. In these cases, imaging was performed for study of tumor extension in 6 patients and diverse medical reasons in 12. Only two therapeutic interventions were performed: endoscopic retrograde cholangiopancreatography (ERCP with insertion of a bile duct stent, and puncture-aspiration-injection-re-aspiration (PAIR, both in patients who did not wish to undergo surgery. Ten patients had surgical indications: CE1 (3 patients, CE3B (5 patients, CE4 (1 patient, and CE5 (1 patient. The reasons why the patients did not undergo surgical treatment were: refusal (9 patients and advanced neoplasm (1 patient. Surgery was judged necessary in 5 patients. In the mean follow-up period of 17 months (range: 1-37, no surgery was performed. Conclusions: there were various causes for not performing surgical intervention of HHD after medical evaluation: asymptomatic patients, older patients, patients with multiple pathologies and oncologic patients. Usually, they were patients who voluntarily chose not to undergo surgery

    Human hydatid disease or cystic echinococcosis (CE), caused by the larval form of cestode Echinococcus granulosus still continues to a common problem in health care environments as different as Europe/North America and resource poor countries of the South America and the East. The Liver is the most frequently parasatized organ in humans. While ultrasonography remains the main diagnostic tool, computed tomography and serology improve the accuracy of diagnosis in Liver hydatid cysts (LHC). Although surgery is the only modality applicable over the entire spectrum of the disease, systemic chemotherapy and percutaneous drainage have evolved as alternative therapies in the last three decades. Various laparoscopic techniques have also been described for safe and optimal management of this entity. In this paper, we review the current management procedures of LHC with particular emphasis on the evidence base and setting specific problems.

    Full Text Available Hydatid cyst is an endemic disease in our country. Most commonly, it occurs in the liver and lungs. Bilateral hydroureteronephrosis is one of the rare presentations of hydatid disease. Herein, we are reporting an unusual case of hydatid disease where the primary mode of presentation was external iliac vein compression with chronic renal failure because of bilateral ureteric involvement. The patient was treated with bilateral double-J stenting to improve the renal function and operated later for removal of hydatid cyst under albendazole drug treatment.

    Full Text Available Taiwan is nearly free from hydatid disease. We report a case of hydatid cyst of the liver in a 37-year-old man who originally lived in India and had migrated to Taiwan 2 years earlier. He presented with right upper quadrant pain and intermittent low-grade fever. Both sonography and computed tomography (CT demonstrated a cystic lesion with vesicles at its periphery in segments 6 and 7 of the liver. A hydatid cyst was diagnosed. The patient underwent radical excision of the cyst with total removal without opening the wall. He also received pre- and postoperative oral mebendazole. Pathology showed a hydatid cyst consisting of three layers: the inner single nucleated geminal layer, the middle acellular laminated layer, and the outer pericyst originating from inflammatory and hepatic cells. This case highlights that accurate preoperative diagnosis of hydatid disease can be made from personal history, typical sonography and CT study in non-endemic areas.

    Full Text Available Hydatid cyst is a parasitic disease which is common in our country and it stil maintains its importance nowadays. In childhood, right lung involvement is more common and hydatid cyst causes symptoms such as fever, cough, chest pain, dyspnea and hemoptysis. We reported a 10-year-old patient who presented with abdominal pain and lesion in the posterior basal segment of the left lung lower lobe compatible with hydatid cyst in thorax CT and in whom cystectomy was performed. In conclusion, in cases presenting with abdominal pain in regions where hydatid disease is endemic, hydatid cyst of the lung should be kept in mind in differential diagnosis.

    The authors report a case of right-sided complete Pancoast and Tobias syndrome related to a multivesicular extrapleural hydatid cyst developing at the cervico-thoracic area with involvement of the first rib. This occurred in a 27 year old country dweller who was a non-smoker who presented with a progressive history of right sided cervico-brachial neuralgia some four months before hospitalisation, there was a subclavicular tumour swelling (8-10 cm), solid, non-inflammatory and a right sided Claude-Bernard-Horner syndrome. Screening of the thorax showed an opacity at the right apex, dense and homogeneous, with a pseudo-fracture of the first right rib. A cervical echo showed a multiloculated liquid filled mass without connection to the thyroid. Computer tomographic scanning showed a multiloculated voluminous liquid filled mass in the right cervico-thoracic area with a regular polycyclic outline, the lungs were normal. The serology was positive for hydatid disease (haemagglutination and ELISA). The patient was operated on by an exclusively supraclavicular approach with excision of the hydatid membranes and vesicles as well as the right first rib. The immediate outcome resulted in the disappearance of the neuralgia and the persistence of the Claude-Bernard-Horner syndrome.

    Full Text Available Hydatid disease, caused by echinococcus granulosus, is a common infectious disease in endemic areas such as Southern Europe and the Middle East. The incidence of this disease, however, is on the increase in Northern Europe due to the migration of labor and also tourism. We report a case of the hydatid cyst of the mediastinum, the diagnosis of which was established by the hemagglutinin test and echocardiography and confirmed by histological examinations. The cyst was totally removed during surgery on beating heart. The patient presented herein demonstrates that the mediastinal and cardiac involvement in hydatid disease could manifest in children with fast growth and rupture.

    Full Text Available Hydatid cyst is the disease of liver and lungs and is common in some regions especially sheep rearing countries of the world, but this disease may occur in any part of world and anywhere in the body. This report presents primary hydatid cysts located in intramuscular region of left side of the abdomen. A 54-year-old female patient from central India, farmer by occupation, non vegetarian by diet came with chief complaints of a painless mass in the left iliac fossa, gradually increasing in size over a period of 6 months. Superficial ultrasound revealed a lesion resembling a hydatid cyst. Surgical excision was done without injuring the cyst. Diagnosis was confirmed on histo-pathological examination and was compatible with a hydatidcyst. Ahydatid cyst should be considered in the differential diagnosis of subcutaneouscystic lesions, it should be excised totally, with an intact wall and postoperative albendazole should be given to avoid recurrence.

    Full Text Available Hydatid disease is still prevalent in developing countries, and isolated cardiac hydatid cysts are the rarest presentation. We report a 40-year-old nondiabetic, nonhypertensive female who presented with low-grade fever for 2 months shortness of breath and orthopnea for 2 weeks. Transthoracic echocardiography revealed a large, round cystic lesion with multiple daughter cysts without any obvious intraluminal detached membranes with mass effect on the left ventricular outflow tract. After total excision, residual tissue was closed with Teflon patch. Germinative membrane and hundreds of daughter cysts were seen. Following total excision of the cyst from myocardium, myocardial cavity was washed thoroughly with 10% Betadine solution. Pathological examination confirmed the diagnosis of hydatid cyst. Preoperatively started albendazole was continued for 4 weeks even after the operation. On follow-up after 4 weeks, the patient is doing well and cardiac imaging showed normal contours of the heart.

    Cystic echinococcosis (CE) is an important helminthic zoonotic disease that commonly affects the liver and lungs. Imaging methods and serology establish the diagnosis in most cases. Chest x-ray can diagnose uncomplicated pulmonary hydatid cysts, whereas superinfection and/or rupture of the hydatid cyst (complicated cysts) may change the radiographic appearance and lead to delayed diagnosis and treatment. We report the case of a patient with hemoptysis and chest pain, where computer tomography scan of the lung suggested a large, ruptured hydatid cyst. However, serological tests with indirect hemagglutination (IHA)for Echinococcus granulosus antibodies were negative, and there was massive growth of Streptococcus pneumoniae in sputum. Based on this, we concluded that the patient had a bacterial lung abscess. The diagnosis of CE was only made after surgical removal of the cyst followed by microscopy and polymerase chain reaction.

    Full Text Available Background: Hydatid disease or echinococcosis is a common parasitic disease of human and bovine, caused by infection with larva of the cestode echinococcus. Liver is the most common organ that is involved in this disease. Pelvic involvement and neurological symptoms, due to mass effect of pelvic involvement, in lower extremities are very uncommon manifestations of the disease.Case presentation: A forty six year old man was referred to clinic of surgery at Ghaem Hospital, Medical University of Mashhad, Iran. The patient complained about weakness and motor impairment in right lower extremity accompanied by numbness and radicular pain over past two months. Physical examination demonstrated muscular atrophy and reduced muscular strength in right lower extremity. Computed tomography and ultrasonographic studies showed a cystic mass in right side of the pelvic cavity with extention to the sciatic notch and another cystic mass in right gluteal region. Surgical operation revealed a cystic mass deep in pelvic cavity with the extention to the right sciatic notch with compression of nerve roots. The cystic mass was contained of daughter cysts which confirmed the diagnosis of hydatid cyst disease. This diagnosis was confirmed by pathologic assessment.Conclusion: Although uncommon, but hydatid disease can involve the pelvic cavity and make a pelvic, usually cystic, mass; that can make compression on nerve roots and so making neurologic symptoms in lower extremities. So in endemic areas for hydatid disease, such as Iran, pelvic hydatid cysts should be considered as a possible differential diagnosis in patients presenting with the sciatic pain and neurological manifestations in whom a pelvic mass has been found too.

    Full Text Available Summary: The rupture of an Echinococcus granulosus hydatid cyst in the spleen due to trauma is a rare event. In this case report we describe the case of a 39-year-old Lebanese male victim of a motor vehicle accident with a ruptured solitary splenic hydatid cyst discovered by CT scan and excised during exploratory laparotomy.Echinococcosis or hydatid disease is a parasitic infestation by the Echinococcus genus of tapeworm. The eggs of E. granulosus, a species of Echinococcus, are fecal-orally transmitted to human hosts, most often from dog feces, and manifest as cystic lesions termed hydatid. E. granulosus most commonly affects the liver (75%, lungs (15%, and rarely the spleen (2–5% [1,2]. E. granulosus is particularly endemic to cattle rearing areas of the Middle East. Infected patients most commonly present with vague abdominal pain, as a result of mass effect or spontaneous rupture of the cyst. Nevertheless, patient presentation may be due to traumatic rupture of a hydatid cyst; however, this is very rare. Herein we report a case of traumatic rupture of a solitary splenic hydatid cyst in a 39-year-old male following a motor vehicle crash, managed following the Advanced Trauma Life Support (ATLS protocol.

    Full Text Available INTRODUCTION: Hydatid disease has a worldwide distribution and causes health problems in endemic countries. The parasite has a "dog - sheep" cycle with man as an intermediate accidental host. When humans ingest the eggs of the tapeworm, the embryos that emer ge penetrate the intestinal mucosa and are transported via the circulation to various organs. Most commonly they reach the liver, lungs and the other organs are rarely affected. Primary hydatid cyst of skeletal muscle is rare, occurring in 1 - 3% of all case s. (1,2 The prevalence of intramuscular hydatid disease is reported to be less than 0.5% , because muscle is an unfavourable site for infestation because of high levels of lactic acid in muscle. (3 The diagnosis is difficult because of the unusual location, low prevalence and complicated cysts may mimic solid or complex lesions. (4 The differential diagnosis in these cases must include malignant soft - tissue tumors such as myxoid liposarcoma, soft tissue abscesses and chronic hematoma. (5 Hydatid disease of h umans caused by Echinococcus granulosus has been recognized as a major public health problem. It is found in all sheep - raising countries of the world. In India, the highest prevalence is reported from Andhra Pradesh and Tamil Nadu. (6 Injudicious approach in the management of these rare presentations may be the root cause of severe anaphylactic shock and systemic dissemination. We report an unusual case of primary hydatidosis of the paraspinal muscles

    Three cases of pulmonary hypertension caused by hydatid emboli from the right side of the heart are described; cardiac catheterisation was performed in 2. One case was confirmed at operation and 2 at necropsy. The pulmonary emboli were caused by hydatid vesicles in all 3 cases and in none was there pulmonary thrombosis; free scolices were found in the pulmonary alveoli in 2. In 1 patient with repeated syncopal attacks there was a pedunculated cyst in the right atrium which was though to have intermittently obstructed the tricuspid valve. Gamma radiography, angiocardiography, and necropsy suggested a mechanical cause for the pulmonary hypertenion with no vasoconstrictive element. The surgical patient was alive and well 18 months later. Images PMID:861098

    Full Text Available Background: Echinococcosis or hydatidosis, caused by the larval stage of Echinococcus granulosus (E. granulosus, is an important public health problem in many areas of the world  and  Iran is a country of endemic situation for hydatidosis In the present study, we evaluated epidemiological, complications and clinical characteristics of hydatidosis at three University Medical Centers in Tehran over a 10-year period.Materials and Methods: This is a descriptive cross-sectional study performed in patients with hydatid cysts. Information about age, gender, number of cysts, organ involvement, morbidity and mortality and relapse were collected from medical records of hydatid patients. Paraclinic information such as CT Scan, MRI, ultrasound, complete blood count, pathological diagnosis and complication of disease were collected.Results: Overall, 81 patients, 35 (43.2% male and 46 (56.8% female, who were diagnosed as having hydatid cyst by clinical and radiological findings, with pathologic documentation were studied in three university medical center registries over a 10-year period (2003- 2012 in Tehran. Fourteen patients (17% of cases had complications resulting from this disease. Patients' age ranged from 5 to 86 years, and the peak prevalence of the disease was between 20 and 40 (34% of cases.Conclusion: Iran  is a country of endemic situation for hydatidosis. Prevalence rate of hydatidosis in Iran was reported to be 0.61-2 in 100000 populations. The highest  rate of infection and complications were in patients of 20-40 years age. Clinical examination revealed that abdominal pain was the most common complaint and was present in 51.7% of the cases. Other most common complain were cough, abdominal mass, dyspnea, icterus, chest pain, dyspepsia, back pain and seizure; and it was result of occupying effect of cysts in organs. This is similar with previous studies in Iran

    2011-01-01

    Full Text Available To emphasize that solitary hydatid cyst can be localized in the soft tissue and present as a soft tissue mass even in an unusual site like face, we report the case of a 42-year-old male patient presenting with a slowly growing mass in right temporal region. Computed tomography (CT scan showed an encapsulated mass with multiple cysts. Histopathological examination revealed the characteristic findings, which were consistent with soft-tissue hydatid disease. In the absence of visceral organ involvement, this is the first reported case of a primary subcutaneous hydatid cyst in the skin of face in India. In the English literature, only one case of this kind has been reported till date. When imaging methods confirm cystic nature of a swelling, even in unusual sites, one should always keep a possibility of hydatid cyst and manage accordingly during surgery to avoid precipitation of acute anaphylaxis.

  20. Scolicidal Agents in Hydatid Cyst Surgery

    Full Text Available Injecting scolicidal solutions into the hydatid cyst and packing the operative field with sponges soaked in scolicidal agents have been used to avoid dissemination of the parasite during surgery. In the first part of this invitro study, we tried to determine the scolicidal property of various agents in different concentrations and exposure times. In the second part, we tested whether sponges soaked in different type and concentrations of scolicidal agents have any role beyond being a mechanical barrier. 20% saline, 3% hydrogen peroxide, 1.5% cetrimide-0.15% chlorhexidine (10% Savlon®, 95% ethyl alcohol, 10% polyvinylpirrolidone-iodine (Betadine® and their further dilutions were used in this study. Protoscoleces were obtained from the cyst containing livers of the sheep and viability was determined with dye-uptake (0.1% Eosin and flame cell activity. Savlon® was found to be the least concentration dependent scolicidal agent among those studied. Scoleces sprayed on sponges soaked in 20% saline, 95% ethyl alcohol, Betadine® and 3% hydrogen peroxide were killed after 15 minutes. 3% and 10% saline and normal saline were ineffective. Sponges work not only as a mechanical barrier but also as a chemical one if the agent is chosen correctly. In purely cystic hydatid liver disease, the risk of dissemination of the cyst contents can be avoided by injection of a potent scolicidal agent such as Savlon®.

    2012-04-01

    Full Text Available Background & objectives: Hydaticosis is a zoonotic helminthic disease of human and other intermediated hosts in which larval stages of the tapeworm Echinococcus granulosu transfect human. The liver and lung are the host tissues for the hydatid cyst . It is unknown which mechanisms are involved in infertility of the cyst and suppression of the fertile cyst. This study was aimed to evaluate the expression of the apoptosis inducing-ligands such as TRAIL and Fas-L in germinal layer of the cyst and human normal tissue surrounding the cyst that is one of the unknown host innate immunity mechanisms against the hydatid cyst.   Methods: In this study, four isolated hydatid cysts were used which had been diagnosed in patients by radiography and parasitological examination in Mashhad Ghaem hospital. Furthermore, the germinal layer of the cyst and accompanied normal peripheral tissues were separated by scalpel in sterile conditions. After homogenization, expression of TRAIL and Fas-L genes were studied by semi-quantitive RT-PCR method.   Results: The TRAIL and Fas-L showed significant higher level expression in germinal layer of infertile cyst than the fertile cyst and host normal tissues.   Conclusion: The host tissue-induced apoptosis of germinal layer of the fertile cysts is probably one of the infertility mechanism in patients with hydaticosis

    2013-03-01

    Scolicidal solutions remain indispensable in the treatment of hydatid cyst disease. Properties of an ideal solution would be inexpensiveness and the promotion of a rapid and complete scolicidal effect with an absence of local and systemic side effects. From this point of view, no ideal solution and agents have been described yet. The aim of the present work was to determine the in vitro effect of high concentrations of thymol against protoscoleces, microcyst and cyst of Echinococcus granulosus and to evaluate its possible role as a scolicidal agent during surgery or PAIR. After short exposure times, a rapid effect was observed depending on the parasitic material. After 2 min of exposure to thymol, viability of protoscoleces was approximately 1.3% at a concentration of 250 μg/ml. The protoscolicidal effect is dose and time dependent. The results of the in vitro treatment with thymol were similar in both microcysts and secondary murine cysts. The employment of SEM and TEM allowed us to examine, at an ultrastructural level, the effects induced by thymol on E. granulosus protoscoleces, microcysts and murine cysts. In conclusion, the data obtained clearly demonstrated that thymol caused severe damages to the parasite even after short incubation times. This fact and the lack of toxicity at the evaluated concentrations, allow us to propose it as a possible scolicidal agent during hydatid cysts surgery and/or PAIR. Copyright © 2012 Elsevier B.V.

    The prevalence of Echinococcus granulosus in dogs in the Turkana District of Kenya was 39.4% of 695 examined. Of these, 98 (35.8%) had heavy Echinococcus worm burdens (10(3)-5 X 10(4) ), while 54 (19.7%) and 122 (44.5%) had medium (201-1000) and light (1-200) burdens. The possible sources of these infections are discussed. The prevalence rate differed in various parts of the district, ranging from 63.5% in the northwest, where the highest incidence of human hydatidosis also occurs, to nil along the shores of Lake Turkana. Infection rates of 32.0% and 16.7% were recorded at Lokitaung (north-east) and Lodwar (central), while in the south 48.9% of dogs harboured Echinococcus. This latter figure is surprising as the area has a low incidence of human hydatidosis. The Turkana keep a large number of dogs, and the reasons for this and the social role of the dog in the district is discussed. No difference in susceptibility was found between Turkana-type dogs and those of mixed breeds from Nairobi when they were experimentally infected with hydatid protoscolices from man, camels, cattle, sheep and goats. However, it proved difficult to infect the Turkana-type of dogs with viable protoscolices of cattle origin. The reasons for this and its epidemiological implications remain unclear. It is suggested that droughts, which affect Turkana every six to ten years, may play an important role in the perpetuation of hydatid disease in the area.

    Full Text Available Abstract Introduction Hydatid disease of the soft tissue is an exceedingly uncommon site to be affected by the tapeworm Echinococcus. The presentation is often vague and misleading. The diagnostic armamentarium has to be supplemented by a meticulously taken history and clinical examination. Case presentation The present case report describes a 33-year-old Saudi male with a painless swelling in the right buttock which turned out to be a primary hydatid disease of the soft tissue. The lump was successfully excised surgically and the patient had an uneventful discharge. Conclusion Surgical excision of the extrahepatic hydatid disease remains the mainstay of treatment; although medical treatment is available for the recurrent and disseminated disease.

    Full Text Available Aspergilloma is a saprophytic infection that colonizes pre-existing cavities in the lung. These cavities are caused by tuberculosis, bronchiectasis, lung cancer and other pulmonary diseases. Development of aspergilloma in the residual cavities after pulmonary hydatid cyst surgery is rarely described in terms of coexistence of the two conditions. We describe 3 cases of pulmonary aspergilloma grafted in a residual cavity of cystectomy for hydatid disease. Resumo: Aspergiloma é uma infecção saprófita que coloniza cavidades pré-existentes no pulmão. Estas cavidades são causadas por tuberculose, bronquiectasias, cancro do pulmão e outras doenças pulmonares. O desenvolvimento de aspergiloma em cavidades residuais, após cirurgia pulmonar de quisto hidático, raramente é descrito em termos de coexistência das duas condições.

    Hydatidosis is a zoonotic disease; human infection occurs through the consumption of food and water contaminated with the eggs of parasites of the Echinococcus type. While the liver is the most common site of infection, involvement of the musculoskeletal system is extremely rare. In the context of musculoskeletal involvement, the spine is the most commonly infected site, while the muscles are rarely infected and account for approximately <1% of cases. It has been suggested that muscles provide an unsuitable environment for the parasite, because of the presence of lactic acid. The cysts appear as slow-growing masses of soft tissue, and signs of inflammation and fistulization often coexist. We report a rare case of an hydatid cyst located in the vastus lateralis muscle of a 41-year-old man. Muscular echinococcosis is an extremely rare disease. A MRI evaluation should be taken into account as gold standard in the diagnosis. Surgical cystectomy is often indicated, and an excision with wide margins is mandatory to avoid the rupture of the cyst and anaphylaxis. Adjuvant pharmacological therapy is recommended to minimize the risk of recurrence.

    Hydatid disease is a helminth infection with various clinical complications caused by the larval stage of the dog tapeworm Echinococcus granulosus. The scolicidal agents have been broadly applied for inactivation of the fertile cysts up to now, but these scolicidal agents have several side effects on patients. Therefore, this study aimed to explore the scolicidal activity of green synthesized gold nanoparticles (AuNPs) utilizing mycelia-free culture filtrate of Penicillium aculeatum against hydatid cyst protoscolices of E. granulosus. The size and morphology of AuNPs were affirmed by UV-visible spectroscopy, scanning electron microscopy (SEM), atomic force microscopy (AFM), and dynamic light scattering (DLS) analysis. The Fourier transform infrared (FT-IR) analysis of AuNPs showed the presence of possible functional groups responsible for the bioreduction and capping. The AuNPs were formed relatively uniform with spherical shape and superior monodispersity with the average diameter of 60 nm. Consequently, various concentrations (0.05, 0.1, 0.2, and 0.3 mg/mL) of green synthesized AuNPs and different exposure times (10, 30, 60, and 120 min) were used against hydatid cyst protoscolices. Statistically, the difference between the scolicidal effects of AuNPs were seen extremely significant for all four concentrations and at various exposure times in comparison to the control group (P < 0.0001). The most mean protoscolex elimination ratio was 94% (0.3 mg/mL AuNPs and 120-min exposure time). The current investigation indicated that applying biogenic AuNPs may be considered as a potential scolicidal agent for cystic hydatid disease. However, further studies are required to evaluate the efficacy of AuNPs in vivo.

  12. Atypical hydatid cyst with psoas muscle location: Case report

    2017-06-01

    Full Text Available Atypical hydatid cysts are detected incidentally. They generally comprise 1–5% of all hydatid cysts. In particular, the peripheral muscles are involved. The literature states that it is seen in many parts of the body, including the iliac crest, psoas muscle, palm, and interdigital spaces. The clinical signs vary according to the involved locations, but wherever there is involvement, the lungs and liver, which are the most commonly involved sites, should be primarily investigated and diagnosed. Diagnosis should also be verified by serological and imaging methods, and it should be determined whether there is other organ involvement. Multidisciplinary management should be used for treatment of this disease. The key element of treatment is surgical. Cases of hydatid cyst with only right psoas muscle involvement are rare. We present this case report so that physicians may keep the definitive diagnosis in mind, as it is most frequently seen in the countryside in our country and it diminishes the workforce.

    Echinococcus granulosus, the aetiological agent of cystic hydatid disease, exists as a series of strains or genotypes which differ in biological features. Pig strain (G7 genotype) has been shown to differ from sheep strain (G1 genotype) in phenotypical characters such as intermediate host range, geographical distribution and rate of development of the adult worm. Since in vivo studies of different parasite genotypes can provide insights into host-parasite relationship we analysed for the first time the behaviour of E. granulosus G7 genotype protoscoleces in the murine experimental model. Our results show that G7 protoscoleces were unable to establish a regular infection in mice in contrast to G1 protoscoleces which developed intraperitoneal hydatid cysts. This inability was observed in co-infection experiments, i.e. even in the presence of a controlled immune response that allows G1 genotype protoscoleces establishment. In addition, the implantation of in vitro obtained E. granulosus G7 genotype microcysts resulted in a low percentage of hydatid cysts establishment. These results show a difference in the biological ability of both E. granulosus strains to develop secondary hydatid cysts in mice. We suggest that the comparison of infective and non infective genotypes of E. granulosus in the experimental host can be regarded as a new model to study the mechanisms of infection of Echinococcus spp. This knowledge could provide helpful information for the development of therapies, drugs and/or vaccines against cystic hydatid disease.

    Full Text Available Hydatid cyst is a zoonotic infection usually caused by Echinococcus granulosus. Hydatid cysts are most often localized in the liver and lungs. Isolated cases of hydatid cyst in soft tissue is very rare. The incidance of isolated soft tissue hydatid cyst is 2.3% in endemic areas. Medical treatment is successful in 30-40% of cases. The first choice of treatment is surgery, especially in atypical localization of hydatid cyst. We aimed to present our patient with ankle hydatid cyst, a rare case in the literature.

    Full Text Available Hydatid cyst of bone constitutes only 0.5 - 2% of all hydatidoses. The thoracic spine is the most common site of spinal hydatidoses. Primary hydatid cyst of the sacral spinal canal is rare. A 23-year-old gentleman had back pain five years ago. At that time he was evaluated and found to have a small cyst in S1 spinal canal, which was presumed to be a benign Tarlov′s cyst; and no treatment was offered. He continued to have back pain and also developed sciatica on the right side. Neurological examination presently revealed right S1 radiculopathy. Magnetic resonance imaging (MRI showed a large multiloculated cystic lesion extending from L5 to S2 spinal canal with bone erosion, both anteriorly and posteriorly. He underwent L5 to S2 laminectomy and excision of multiple cysts. The whole cyst was excised and cavity irrigated with sterilized formalin. A laparoscope was introduced in the cavity to look for extension into the pelvis and to confirm complete excision. Postoperatively, the patient received albendazole for two months. At 16 months follow-up the patient was asymptomatic. Hydatid cyst of sacrum is rare and can be missed at initial presentation. If the patient with a cystic lesion of sacral continues to have symptoms the diagnosis should be revaluated and prompt treatment should be offered.

    Full Text Available Background & Objectives: The most common parasitic lung disease is echinococcosis, and usually young male patients suffer from this disease. Lung involvement is more common in children, and it is important to consider this involvement as a diagnosis. Anesthesia and surgical management are always challenging for both Anesthesiologist and surgeon.  Case: In this case we report successful anesthetic and surgical management of a giant hydatid cyst in the lung of an eight-year-old boy. Conclusion: Successful anesthetic management during hydatid cyst surgery of lung in pediatrics using cuffed endobronchial tube is possible if the anesthesiologist and the surgeon are swift, well-coordinated, and synchronized.

    Hydatid disease remains a public health problem in many Mediterranean countries. Liver and lung localizations are the most common. Renal hydatid cysts represent 2 percent to 4 percent of the visceral forms of this disease. To the best of our knowledge a scrotal location has only previously been described in five papers in the literature, all being secondary localizations. In this paper, we report a case of a primitive scrotal hydatid cyst. A Moroccan man aged 29 years old presented to our facility with scrotal pain. A clinical examination identified a painless scrotal mass. The results of a scrotal ultrasound showed intra-scrotal cystic formations with different sizes associated with scrotal effusion of average abundance. Chest cavity and abdominal computed tomography scans did not reveal any other localizations. Our patient benefited from surgical protruding dome resection. A partial cysto-pericystectomy was realized. The first stage consisted of injecting a scolicide solution; hydrogen peroxide is the most commonly used agent. This is injected into the cystic cavity and retained for 10 minutes. This process allows for sterilization of the cyst while avoiding the risk of rupture and transmission of the hydatid liquid into the circulation. After 10 minutes, the cystic contents are removed by suction. The cyst is then opened, and the endocyst containing the hydatid membrane and daughter vesicles are removed. It is of note that our patient did not receive any additional medical treatment. Our diagnosis was made using an imaging approach and was confirmed during surgery. Ultrasound is often the key diagnostic approach for cases of a scrotal hydatid cyst. Treatment is primarily surgical, aiming for resection of the protruding dome via a longitudinal scrotectomy.

    Full Text Available Abstract Introduction: Echinococcosis or hydatid cyst disease is one of the most common infectious diseases between animals and humans (zoonosis that is endemic in all the countries of the Mediterranean region, including Iran. Pelvic involvement is rare, and the involvement of the uterus is very rare. Case Report: 26-year-old female patient complained of limb paresis, ataxia and progressive headaches diagnosed with hydatid cyst of the brain was undergone surgery. The pain and slight swelling in the area of the wrist occurred, one year later and with the same diagnosis, surgery was performed again. Abdominal ultrasound showed two cystic lesions in the suprapubic region with a diagnosis of hydatid cyst of the uterus, 3 years later, surgery was performed. In all cases, the diagnosis was confirmed by pathology. Discussion: Follow-up of patients with radiologic and serologic methods is necessary. Conclusion: In patients with any clinical manifestation of endemic areas, particularly if there is a previous history of hydatidosis, hydatid cyst should be considered in terms of risk.

    The breast is a rare primary site of hydatid disease and accounts for only 0.27% of cases. Mammary hydatidosis generally occurs in females and has never been described in male patients. In this paper, the authors report a new case of isolated hydatid cyst of the breast in a 35-year-old previously healthy man, who presented with a left breast painless lump of one year duration. Physical examination showed a non-tender and immobile mass in the upper lateral quadrant of the left breast, with normal overlying skin and nipple. There was no palpable lymph node in the left axilla and the contralateral breast was normal. Ultrasonography showed a 2.7 x 1.5 cm cystic lesion in the left breast. The patient underwent total excision of the mass, and histopathological examination confirmed the diagnosis of hydatid cyst. The authors conclude that although hydatid cyst of the breast is rare, it should be considered in the differential diagnosis of breast lumps especially in endemic areas.

    Hypernatremia is a rare but fatal complication of hypertonic saline (HS) irrigation in hepatic hydatid disease. It needs careful monitoring and treatment. A 28-year-old woman with hepatic hydatid cysts who received operation treatment developed electrolyte disturbances. We also conducted a retrospective study about influence of HS application on electrolytes in patients with hepatic hydatid disease receiving surgery. Hypernatremia, developed after HS irrigation. Normal saline, 5% dextrose and other supportive treatment were administered. In the retrospective study, a comparison of electrolyte and glucose fluctuation was made among different HS application groups. The patient developed hypernatremia after irrigation with HS and died from severe complications. Although some cases of complications are found, no significant relationship between HS irrigation and hypernatremia was reported according to the retrospective study. Hypernatremia after HS irrigation remains rare but might cause severe complications. Monitoring and appropriate treatment are needed to improve prognosis.

    Full Text Available The impact of ultrashort nanopulse on cellular membrane is of biological significance and thus has been studied intensively. Different from cell study, this ex vivo study aims to investigate the biological effects of nanosecond pulsed electric field (nsPEF on an independent multimembrane parasite, human hydatid cyst, to observe the unique influence of nanopulse on macromembrane structure, permeabilization, and biochemistry. The 300 ns nsPEF was delivered on an experimental model of single human hydatid cyst ex vivo with eight different parameters. Then pathological changes during 7 days of 48 parasite cysts were followed up after nsPEF. The laminated layer, the germinal layer, the protoscolex, and cyst fluid were evaluated by the morphological, pathological, and biochemical measurements. The parameter screening found that nsPEF can damage hydatid cyst effectively when the field strength is higher than 14 kV/cm. When nsPEF is higher than 29 kV/cm, nsPEF destroy hydatid cyst completely by collapsing the germinal layer, destructing protoscolices, and exhausting the nutrition.

    Borderline ovarian tumors (BOTs) represent a heterogeneous group of ovarian epithelial neoplasms. Despite a favorable prognosis, 10-20% of BOTs exhibit progressively worsening clinic. Primary involvement of pelvic organs with echinococcus is very rare. Lymphoepithelioma-like gastric carcinoma is a rare neoplasm of the stomach. A 58-year-old woman referred with abdominal swelling and gastric complaints. Imaging studies revealed a huge cystic mass with multiple septations and solid component, another cystic mass with an appearance of cyst hydatid in the pelvis, and thickening of the small curvature of stomach. Gastroscopy revealed an ulcer with a suspicious malignant appearance, and histology of the endoscopic specimen showed severe chronic inflammation and lymphocytic infiltration. No other involvement of hydatid cyst was detected. In the exploration, there was a 25cm cystic lesion with solid components arising from right ovary, another 6cm cyst over the former, 7cm cystic lesion arising from left ovary, and 10cm mass near the small curvature of the stomach. Excision of the masses; total gastrectomy with esophagojejunal anastomosis; total abdominal hysterectomy; bilateral salpingo-oophorectomy; omentectomy; appendectomy; splenectomy; and pelvic, paraaortic, and coeliac lympadenectomy were performed. Final pathology revealed lymphoepithelioma-like gastric carcinoma, bilateral serous BOT, and hydatid cyst. Hydatid cyst should always be considered in the differential diagnosis of abdominopelvic masses in endemic regions of the world. Preoperative diagnosis of primary pelvic hydatid disease is difficult and awareness of its possibility is very important especially in patients residing in or coming from endemic areas.

    Full Text Available Introduction : The objective of this study was to give a description of the most prominent atypical radiological presentations of lung hydatidosis. Materials and methods: All patients diagnosed with pulmonary hydatidosis by surgical exploration were included in this study. Standard chest roentgenogram and computed tomography CT were evaluated before surgery for lung cysts or unknown lesions. Radiological findings were divided into two categories: 1- Typical hydatid cysts that were previously presented by imaging as a hydatid cyst in the form of an intact cyst, water lily sign and crescent sign. 2- Atypical hydatid cysts that were not similar to typical previously mentioned hydatid cysts. Results: During a 26-year period, 1024 subjects with pulmonary hydatidosis were diagnosed and operated on. Chest X-rays (interpreted in 832 cases showed perforated cysts in 190 (23% and atypical findings such as mass, alveolar type infiltration, abscess and collapse in 113 (13% patients. Seventy-nine patients had a thoracic CT scan in which atypical cysts were detected in 32 subjects (40.5% such as: thick wall cavity in 9 patients (28%, solid masses in 7 (21%, abscesses in 6 (18%, consolidation in 3 (9%, fungus balls in 3 (9%, collapse (atelectasis in 2 (6% and round pneumonia in 2 (6%. Cavity was significantly more frequent in the right lung (90% and mass-like opacity was significantly more frequent in the lower lung field (100%. Conclusion: Hydatid cysts should be considered for most of localized radiological pictures of the lung without respect to localization, size and count of lesions.

    The results are given of a study on the role of wildlife in the transmission of Echinococcus granulosus in the Turkana and Narok Districts of Kenya. A total of 76 wild carnivores belonging to three separate species was examined from Turkana District. Echinococcus adults were found in 11 of 38 silver-backed jackals (Canis mesomelas) and in six of 22 golden jackals (Canis aureus). This is the first record of golden jackals being infected with this parasite in Kenya. None of 16 spotted hyaenas (Crocuta crocuta) harboured the parasite. Morphological features of the parasites obtained from the jackals were compared with material obtained from dogs in the same area. No morphological differences were recorded when this material was compared with data reported by others, hence the Turkana material belonged to the single species E. granulosus. Three silver-backed jackals and three puppies (Canis familiaris) were successfully infected with protoscolices obtained from a hydatid cyst surgically removed from a Turkana patient. Three spotted hyaenas fed the same material failed to become infected. None of 152 wild herbivores of five species examined in Turkana harboured hydatid cysts. The natural jackal infections in this District are thought to be incidental and dependent on the continuance of the domestic cycle. The role of the Turkana themselves in the perpetuation of the cycle is discussed. Twenty-six wild herbivores of six species were examined for hydatid cysts, in Narok District; hydatids were found in three wildebeest (Connochaetes taurinus) and a single topi (Damaliscus korrigum). The discovery of fertile cysts in wildebeest and the reported infections in lions (Panthera leo), Cape hunting dogs (Lycaon pictus) and silver-backed jackals, support previous evidence of the existence of a wildlife cycle in the Masailand and Serengeti regions of East Africa. The relationship of this cycle to the domestic cycle operating in the same area is unclear and requires further

    Full Text Available Ruptured pulmonary hydatid cyst may sometimes cause complications like empyema, bronchopleural fistula, and collapsed lung. These complications may mislead the diagnosis and treatment if prior evidence of cyst has not been documented before rupture. We present a case of a young male who presented with complete collapse of left lung with pyopneumothorax and bronchopleural fistula which was misdiagnosed as pulmonary tuberculosis. He was referred to us from peripheral hospital for pneumonectomy when his condition did not improve after six months of antitubercular chemotherapy and intercostals drainage. On investigation, CT scan revealed significant pleural thickening and massive pneumothorax restricting lung expansion. Decortication of thickened parietal and visceral pleura revealed a ruptured hydatid endocyst, and repair of leaking bronchial openings in floor of probable site of rupture in left upper lobe helped in the complete expansion of the collapsed lung followed by uneventful recovery.

    We report a case of renal hydatid cyst in a 25-year-old male who presented with hydatiduria. Intravenous pyelography revealed presence of a space-occupying lesion in the lower pole of right kidney with curvilinear calcifications. Ultrasound, computed tomography and MRI were suggestive of hydatid cyst in the right kidney. Patient underwent right-sided nephrectomy. Passage of hydatid cysts in urine is an exceedingly rare occurrence. Urinary tract involvement develops in 2-4% of all cases of hydatid cyst. Hydatiduria is an extremely rare manifestation of renal hydatid cyst. We report such a case with emphasis on IVU, sonographic, CT and MRI findings.

    Full Text Available Background Cystic echinococcosis (CE is a cosmopolitan zoonotic infection which is considered as a significant public health and economic concern. Livestock is the main intermediate host for Echinococcus granulosus. Objectives This study was conducted to evaluate the prevalence and fertility rate of hydatid cyst among livestock in Hamadan area, western Iran. Methods A total of 10626 livestock carcasses were examined through visual inspection in order to detect hydatid cyst in Hamadan industrial slaughterhouse, during 2015 - 2016. The viability and fertility of hydatid cyst were determined microscopically by flame cell activity and eosin dye uptake. Results The carcasses, including 8684 sheep, 1110 goats and 832 cattle were inspected in order to detect hydatid cyst. An overall CE was detected in 3% of the inspected carcasses with a prevalence rate of 5.3% in cattle, 3% in sheep and 1% in goats (P < 0.001. The prevalence rate of infection in the females (2.7% was more than males (0.3% (P < 0.001. All of the infected animals were aged one year or more. The highest rate of infection in internal organs was found in the lungs (47.2%. The highest and the lowest fertility rate of hydatid cyst were observed in sheep (69.3% and cattle (6.8%, respectively. The most of hydatid cysts which obtained from cattle (79.6% were suppurative or calcified. Conclusions This study shows that the prevalence rate of CE is considerable in the area and sheep appear to be the most important intermediate hosts for E. granulosus tapeworm.

  3. Evidence that a hydatid cyst is seldom "as old as the patient".

    Human hydatid disease caused by the strain of Echinococcus granulosus endemic in Australia and New Zeland has been regarded as a very lonstanding condition, and most cysts diagnosed in adults were believed to have resulted from infection in childhood. A significant drop in the number of new cases among people and 25 and over (P less than 0.05) in two hydatid-control programmes makes it necessary to revise this view. In both Tasmania (P greater than 0.50) and New Zealand (0.50 greater than P greater than 0.10) the incidence was halved without significantly altering the age-distribution. These findings indicate that adults are relatively susceptible and that the latent period between infection and diagnosis in many cases is only a few years.

    Full Text Available Background. Hydatid cyst is an endemic disease frequently localized to the liver. It is frequently observed in Southeast Europe, Middle East, and Turkey. Although the cyst rupture can occur spontaneously, it can also occur upon albendazole treatment. Its surgical treatment includes cystotomy, capitonnage, and wedge resection. Material-Method. A 56-year-old male immigrant was admitted with fever, pain, and cough. Albendazole treatment was initiated and elective surgery was planned. Upon his admission to emergency service, he was diagnosed with pneumonia, and a spontaneous cyst rupture was detected. Result. Thoracotomy and cystotomy were performed. Bile leakage aspiration and lung wedge resection were also performed. Conclusion. Different surgical methods are used in the treatment of hydatid cysts depending on the localization and complications. Follow-up with antihelminthic drugs such as albendazole and mebendazole is recommended in medical treatment.

    Full Text Available Hydatid disease is not common in human populations of highly developed urban areas. However, increasing immigration,travel and international tourism have led to a recent increase in incidence. Surgery remains the method ofchoice in the management of hepatic hydatid cysts. Laparoscopic treatment of the disease has been questionable sofar, though it is feasible and safe in use. We report a case of an 18-year-old woman, successfully treated with total cystectomylocated in a favourable laparoscopic area – the border of the 3rd and 4th segment of the hepatic left lobe. Theoperation and hospitalization period were uncomplicated. Controlled follow-up laboratory and radiological testsshowed no remaining pathology or recurrence in any form. In conclusion we state that the laparoscopic techniqueprovides a feasible and efficacious option of treatment for some types of hydatid cysts located in the liver. It is a safeminiinvasive surgical approach which enables postoperative discomfort to be reduced and results in a quick recovery.

    Surgery for hydatid cyst of the liver is widely practiced worldwide; this type of management is still associated with high mortality and morbidity. The aim of this study is to find out possible predictors for this high mortality and morbidity. The medical records of 169 patients who underwent surgery for hydatid cyst of the liver were retrospectively reviewed. The mortality and the morbidity rates were assessed as well as the following eight potential predictors of mortality and morbidity: age of the patients, size of the cyst, number of cysts, other organs involved by the disease, the presence of preoperative complications, the type of surgery performed (radical or conservative), whether the disease was new or recurrent, and when surgery was performed in the first period (1973-1986) or in the second period (1987-1999). Cross-tabulation and logistic regression between mortality and morbidity (dependent variable) and the above-mentioned eight potential predictors (independent variables) were carried out. Of the 169 patients, 112 were female subjects and 57 male subjects, the age range was from 5 to 85 years (mean=39.2 years), the mortality rate was 6.5% (n=11), and the overall morbidity rate was 53.8% (n=91), while specific complications of liver hydatid cyst surgery were seen in 32% (n=54). Patients of age >40 years, with a cyst diameter of >10 cm, who presented with pre-operative complications, who had conservative surgery, and who had surgery before 1987 were having a significantly higher mortality and morbidity rate. Age, size of the cyst, the presence of pre-operative complications particularly cyst-biliary communication, and type of surgical procedure performed (conservative or radical) represent as significant predictors of mortality and morbidity of surgery for liver hydatid cyst.

    Spinal epidural localization of hydatid cyst is quite rare. We report a case of a 33-year-old patient who experienced paraparesis over 2 years, with an umbilical sensitive level. A CT scan and MRI showed an intrathoracic multilobar lesion, probably of intra-spinal origin. An anterolateral transpleural surgical approach confirmed the hydatic character of the observed lesion and enabled total spinal cord decompression. No osseous involvement was noted. We report a case of spinal epidural hydatid cyst successfully managed by an anterior approach, and we discuss epidemiological, diagnosis, and therapeutical features of this rare localization of hydatid cyst.

    Surgery is still the main treatment for hydatid disease. Recurrence of the infection is one of the end points of surgery in treating the hydatid cyst which results from the dissemination of protoscolices-rich fluid. Installation of a scolicidal agent into the cyst is the most commonly employed measure to prevent recurrence. Many scolicidal agents have been used for inactivation of the cyst's content, but most of them are not safe due to their undesired side effects. In the present study, the scolicidal effect of methanolic extract of Allium sativum is investigated. Protoscolices were aseptically collected from sheep livers containing hydatid cysts. Two concentrations (25 and 50 mg ml(-1)) of garlic extract were used for 10, 20, 30, 40, 50, and 60 min. Viability of protoscolices was confirmed by 0.1% eosin staining. Allium sativum extract at the concentration of 25 mg ml(-1) killed 87.9, 95.6, 96.8, 98.7, 99.6, and 100% of protoscolices following 10, 20, 30, 40, 50, and 60 min of application, respectively. Moreover, the scolicidal activity of Allium sativum extract at the concentration of 50 mg ml(-1) was 100% after 10 min of application. Methanolic extract of Allium sativum had a high scolicidal activity in vitro and thus might be used as a scolicidal agent in the surgical treatment of the hydatid cyst. However, further investigation on the in vivo efficacy of Allium sativum extract and its possible side effects is proposed.

    Full Text Available Introduction: Cystic echinococcosis (CE is one of the important helminthic diseases of human and animals, which causes by Echinococcus granulosus. Canids are its definite and grazers especially sheep, and cattle, and also wild herbivores are its intermediate hosts. Human can also be accidentally infected by a parasite. This study aimed to investigate genotypes of the hydatid cysts isolated from hydatidosis patients in order to confine the source of the infection, 2013. Methods: In this cross-sectional study 55 paraffin blocks of identified hydatid cysts have been undergone genotyping using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP technique. The ITS1 region of rDNA has been amplified using BD1 forward and 4s reverse primers. PCR products have been digested using HpaII and RsaI restriction endonucleases. RFLP products studied using gel electrophoresis. Data were analyzed using SPSS for Windows using the chi-square test. Results: About 29 (52.72%, 16 (29.1%, 3 (5.45%, 3 (5.45%, 1 (1.81%, 1 (1.81%, 1 (1.81% and 1 (1.81% out of 55 hydatid cysts were located in lung, liver, spleen, kidney, heart, pancreas, brain, and femore, respectively. The frequency of hydatidosis observed higher in patients from rural areas (P = 0.013; odds ratio = 0.599; 95% confidence interval: 0.28, 1.27. Based on RFLP results, the entire studied hydatid cysts identified as sheep strain (G1. Conclusion: According to the results of the present observation, it can be concluded that the majority of cases of human hydatidosis in East Azerbaijan Province are caused by sheep strain (G1 of E. granulosus, which indicates the sheep-doge cycle in the studied area.

    Full Text Available Introduction The aim of this study was to explore the environment of Echinococcus granulosus (E. granulosus protoscolices and their relationship with their host. Methods Proteins from the hydatid-cyst fluid (HCF from E. granulosus were identified by proteomics. An inductively coupled plasma atomic emission spectrometer (ICP-AES was used to determine the elements, an automatic biochemical analyzer was used to detect the types and levels of biochemical indices, and an automatic amino acid analyzer was used to detect the types and levels of amino acids in the E. granulosus HCF. Results I Approximately 30 protein spots and 21 peptide mass fingerprints (PMF were acquired in the two-dimensional gel electrophoresis (2-DE pattern of hydatid fluid; II We detected 10 chemical elements in the cyst fluid, including sodium, potassium, calcium, magnesium, copper, and zinc; III We measured 19 biochemical metabolites in the cyst fluid, and the amount of most of these metabolites was lower than that in normal human serum; IV We detected 17 free amino acids and measured some of these, including alanine, glycine, and valine. Conclusions We identified and measured many chemical components of the cyst fluid, providing a theoretical basis for developing new drugs to prevent and treat hydatid disease by inhibiting or blocking nutrition, metabolism, and other functions of the pathogen.

    Full Text Available A 25-year-old farmer from rural Bengal presented in the emergency with acute retention of urine and severe radicular pain along the lower back and back of thighs. He had a history suggestive of bladder outflow obstruction for past 1-year, but no history of retention of urine. Radicular pain and marked constipation were of recent onset. There was no history suggestive of urinary tract infection or significant weight loss. There was no past history of surgery, trauma or other major illness. On examination, the bladder was distended and digital rectal examination revealed an anteriorly placed immobile, nontender, extra luminal soft, cystic pelvic mass. Ultrasonography revealed a cystic mass within pelvis with back pressure changes of the kidneys and ureters, while contrast enhanced computed tomography of abdomen revealed a 10.5 cm × 10 cm thick-walled, nonenhancing, unilocular lesion occupying the pouch of Douglas pressing on the bladder neck anteriorly. An ELISA test for echinococcus antigen was negative. Laparotomy revealed an immobile, retroperitoneal, tense, cystic swelling occupying the entire pelvic cavity containing crystal clear fluid suggesting possibility of hydatid cyst. Exploration of the cyst with scrupulous precautions to avoid spillage showed an endocyst. Endocystectomy with partial pericystectomy was done. Patient had an uneventful recovery. This case report depicts an atypical presentation of isolated primary extra-peritoneal pelvic hydatid cyst in a young male hailing from a nonendemic areas.

    Full Text Available Hydatidosis due to Echinococcus granulosus is an endemic parasitic zoonosis characterized by worldwide distribution particularly in Mediterranean countries. The most commonly involved anatomical locations are the liver and lung. Occasionally the cyst may progressively increase in size, mimicking gross ascites or intrabdominal tumor. Herein, are reported a case of a 40-year-old patient with a giant exophytically expanded hepatic echinococcus cyst, misdiagnosed as an abdominal malignancy during formal investigation. The patient was admitted to the hospital complaining for mild diffuse abdominal tenderness, moderate abdominal pain, nausea, diarrhoea, and vomiting. A CT scan revealed the presence of a giant abdominal mass 25×21×14 cm, resembling a tumor, adherent to the liver edges and parietal peritoneum, displacing intestinal loops. During the ensuing days the patient’s clinical condition worsened, and he became febrile. Exploratory laparotomy was performed, and an exophytically grown giant liver hydatid cyst was removed, despite the radiological findings and the preoperative clinical suspicion.

    Hydatid cyst (HC) disease is a serious health problem in endemic areas. It is a parasitic infection that commonly involves liver and lungs while muscular HC is rare. HC of abdominal wall was reported only six times. We reported a 39-year-old male presented with HC of the right loin who was managed surgically with brief literature review. HC should be put in the differential diagnosis of the abdominal wall masses. Its pre-operative diagnosis is important to prevent rupture with subsequent anaphylaxis and recurrence.

    Full Text Available The aim of this work was to assess the influence in the diagnostic value for human hydatid disease of the composition of bovine hydatid cyst fluid (BHCF obtained from fertile (FC and non-fertile cysts (NFC. Eight batches from FC and 5 from NFC were prepared and analysed with respect to chemical composition: total protein, host-derived protein, carbohydrate and lipid contents. No differences were observed in the first two parameters but carbohydrate and lipid contents were shown to be higher in batches from FC than in those from NFC. Bands of 38 and 116 kD in SDS-PAGE profiles were observed to be present in BHCF from FC only. Two pools were prepared from BHCF batches obtained from FC (PFC and NFC (PNFC, respectively. Antigen recognition patterns were analysed by immunoblot. Physicochemical conditions for adsorption of antigens to the polystyrene surface (ELISA plates were optimized. The diagnostic value of both types of BHCF as well as the diagnostic relevance of oxidation of their carbohydrate moieties with periodate were assessed by ELISA using 42 serum samples from hydatid patients, 41 from patients with other disorders, and 15 from healthy donors. Reactivity of all sera against native antigen were tested with and without free phosphorylcholine. The best diagnostic efficiency was observed using BHCF from periodate-treated PFC using glycine buffer with strong ionic strength to coat ELISA plates.O objetivo do presente trabalho foi testar a composição química do líquido hidático bovino (BHCF obtido de cistos hidáticos férteis (FC e não férteis (NFC.

    Full Text Available Hydatid disease in human beings, as in all intermediate hosts, manifest as hydatid cyst (HC. It is an important cyclozoonotic disease, endemic in various sheep and cattle raising areas of the world, including India. The tapeworm commonly involved is Echinococcus granulosus. HC can occur almost anywhere in the body, most common organs being liver and lungs, and are usually solitary. In 25% of cases combination of liver HC with HC in other extra pulmonary locations are found. Cardiac HCs comprise of 0.5–2% of all HC cases. Within the heart, HCs are usually situated in the left or right ventricle and rarely found in the peri-cardium. Pericardial HC does not produce symptoms and is often painless and silent, until the cysts grow to a large size over the years, when the usual complications develop, such as cyst rupture, cardiac compression, atrial fibrillation, and even sudden death. We describe the case of a 39 year old house wife, of rural origin, with proximity to livestock, who had an asymptomatic pericardial HC along with a symptomatic hepatic HC. She clinically presented with an abdominal lump for one year with recent onset of abdominal pain for 1 month, when radiological imaging confirmed the diagnosis of an unruptured hepatic HC and a pericardial HC. The patient recovered after pericardiectomy along with excision of the HC over the left ventricle and enucleation of hepatic HC, by thoracoabdominal approach. She is doing well after 5 years of followup without recurrence.

    he s Because there is no effective and safe drug therapy for hydatid cyst, finding of some new agents especially from herbal origin with a desired scolicidal effect attracts great attention for treatment and pre-surgical use to prevent the hydatid cyst recurrence. In this study, the scolicidal effect of ultrasonic methanol extract of Garlic (Allium sativum) flower is investigated. Protoscolices were collected aseptically from sheep livers containing hydatid cyst and were exposed to different concentrations of extract for various exposure times. The viability of protoscolices was confirmed by 0.1% Eosin staining. The scolicidal activity of extract at a concentration of 50 mg ml-1 was 59, 76, 81 and 86% after 10, 30, 60, and 180 min of exposure respectively. The scolicidal effect at 100 mg ml-1 was 67, 78, 85 and 98% after various exposure times, respectively. The results of this study showed that the ultrasonic extract has high scolicidal activity and might be used as a natural scolicidal agent. Garlic flower extracts is a potent protoscolicid and might be used in hydatid cyst treatment and pre-surgery to prevent secondary cyst recurrence.

    Full Text Available Surgery is the preferred treatment for hydatid cyst (cystic echinococcosis, CE. At present, various scolicidal agents have been used for inactivation of protoscoleces during surgery, but they are associated with adverse side effects. The aim of the present study was to evaluate the scolicidal effects of amphotricin B, Silver nano particles, Foeniculum vulgare Mill, essential oil and hypertonic saline against protoscoleces of hydatid cyst on an in vitro model.Protoscoleces were aseptically aspirated from the naturally infected livers of sheep and goats. Various concentrations of AmB (2.5-20 mg/ml, Ag-NPs (0.5-4 mg/ml, F. vulgare essential oil (0.125-1 mg/ml and hypertonic saline (10-20% were used for 5-60 min. Eosin exclusion test was used to determine the viability of protoscoleces.Maximum protoscolicidal effect of AmB and Ag-NPs was found at concentrations of 20 and 4 mg/mL, resulting in only 82.3% and 71.6% of the protoscoleces after 60 min of incubation, respectively. In contrast, F. vulgare essential oil at concentration of 1 mg/ml and hypertonic saline 20% killed 100% protoscoleces after 5 and 10 min of exposure, respectively.The results indicated weak scolicidal activity of AmB and Ag-NPs; whereas F. vulgare essential oil had potent scolicidal activity against protoscoleces of hydatid cyst that revealed the potential of F. vulgare as a natural source for the production of new scolicidal agent for use in hydatid cyst surgery. However, further studies will be needed to confirm these results by checking the essential oil and its active component in the in vivo model.

  9. A Hydatid Cyst of the Lumbar Spine: A Rare Cause of Paraplegia

    2017-05-01

    Full Text Available Introduction Hydatid cyst is a zoonotic disease, affecting humans and other mammals worldwide. It is caused by tapeworms of the genus Echinococcus, which is most frequently encountered in the liver and lungs. Although involvement of the central nervous system and spine is rare, it can lead to severe neurological deficits due to direct compression. Case Presentation We report a case of intradural extramedullary hydatid cyst in the lumbar region with a sudden onset, causing progressive paraplegia and areflexia over the past 20 days. After surgical removal, the cyst was sent for histopathological examination. The results showed inner laminated membranes and an outer fibrous layer, surrounded by foreign-body giant cells. The primary objective during surgery was to avoid perforation of the cyst, thereby reducing the risk of systemic dissemination and local seeding of the parasite. During the postoperative period, there was a steady improvement in the neurological deficit, and the patient was discharged with anthelmintics to prevent any distant dissemination. Conclusions An accurate and precise diagnosis is necessary when dealing with cystic pathologies.

    Full Text Available Background & aim: Given the existence of 10 different genotypes of the parasite Echinococcus granulosus from different hosts and intermediate and final impact of these genotypes in the life cycle of the parasite and its transmission to humans, the purpose of this study was to determine the molecular characterization of isolates of hydatid cysts in industrial slaughterhouses of Yasuj city. Methods: In this study, 93 animal isolates (56 goat, 31 sheep and 6 cattle were collected from the industrial slaughterhouse of Yasuj city. The genomic DNA corresponding to protoscolices was extracted, using the standard Phenol–Chloroform method. The fragment of DNA-ITSI of each sample was assessed by PCR with designed primers of EgF, EgR and then amplified. Moreover, the PCR products were assessed by electrophoresis and digested by the Alu I and Rsa I enzymes. RFLP products were evaluated by electrophoresis. Results: Using a PCR test, rDNA-ITSI of all isolates of similar size bands and 1000 bp were obtained respectively.The patterns generated by RFLP using Alu I and Rsa I enzymes, showed Echinococcus granulosus G1 genotype in all isolates. Conclusion: This study showed that strain G1 is the predominant strain causing hydatid cysts in different organs of the animal in Yasuj.

    Full Text Available Thoracobiliary fistula is a rare complication of hydatid cystdisease of the liver especially in calcified form. Given the rarityand high mortality of such fistula, it is not surprising thatthere is no consensus about surgical treatment of this condition.In the present paper we report two cases of thoracobiliaryfistula of complicated calcified hydatid cyst of the liver. A 64-year-old man with cough and biliary sputum and a 66-year-oldman with cough and right biliary pleural effusion (pleurobiliaryfistula. The patients underwent left hepatectomy withcholecystectomy and T-tube choledochal drainage in one patientand successful decortication of the lung, and cystectomywith excision of calcified pericystectomy of the liver in anotherpatient. Pathologic examinations revealed calcified hydatidcysts of the liver. Because of poor prognosis of thoracobiliaryfistula, radical surgical intervention is recommended.

    Full Text Available Cystic hydatid disease is a zoonosis caused by Echinococcus granulosus. It may affect any organ and tissue in the body, in particular the liver and Lung. Musculoskeletal or soft tissue hydatidosis accounts for about 0,5%–5% of all echinococcal infections in endemic areas and is almost secondary to the hepatic or pulmonary disease (Karaman et al., 2011; Dirican et al., 2008; Kouskos et al., 2007. Case Presentation. We report an unusual case of primary subcutaneous hydatidosis in the left supraclavicular region of the neck. A 53-year-old female patient was admitted with three-month history of pain and gradually growing mass located in the left supraclavicular region. Physical examination revealed a moderately hard, painful, and erythematous mass. The blood cell count was normal. Computed tomography demonstrated, a multilocular cystic lesion with thin borders and thin wall. The mass is binocular and extends to the scapula. CT showed no involvement of the lung. From these signs, the patient was diagnosed as having abscess (bacterial infection or tuberculosis. The diagnosis of Echinococcus granulosus infection was made per operatively after visualization of the cyst wall and the daughter cysts. Following irrigation of cystic cavity with hypertonic saline solution, the cyst wall was excised along with a portion of surrounding tissue. Histopathological examination of the specimen confirmed the hydatid origin. Hemagglutination tests for Echinococcus and ELISA were negative. Ultrasound of the abdomen was normal. The patient received albendazole (400 mg/day for 8 weeks postoperatively. No sign of recurrence could be detected by physical examination and imaging (CT at 4-month followup. Conclusion. The case illustrates that echinococcal disease should be considered in the differential diagnosis of every cystic mass in every anatomic location, especially when it occurs in endemic areas.

    Full Text Available Hydatid disease is a zoonotic infection caused by larval stages of dog tapeworms belonging to the genus Echinococcus (family taeniidae and is also referred to as echinococcosis. Human cystic echinococcosis caused by E. granulosus is the most common presentation and probably accounts for more than 95% of the estimated 2-3 million annual worldwide cases. The liver (70–80% and lungs (15–25% are the most frequent locations for echinococcal cysts. The diagnosis is made through the combined assessment of clinical, radiological, and laboratory findings. The treatment is mainly surgical, and, with appropriate diagnosis and treatment, prognosis is good. With advances and increasing experience in laparoscopic surgery, many more attempts have been made to offer the advantage of such a procedure to these patients (Chowbey et al. (2003.

    Uzbekistan is endemic of cystic echinococcosis (CE). In order to estimate endemicity of CE, we collected data from emergency surgery due to CE in 2002-2010 and also investigated the prevalence of hydatid cysts in the liver and lungs of sheep at an abattoir in Uzbekistan from July 2009 to June 2010. In 14 emergency hospitals, 8,014 patients received surgical removal or drainage of CE during 2002-2010, and 2,966 patients were found in 2010. A total of 22,959 sheep were grossly examined of their liver and lungs, and 479 (2.1%) and 340 (1.5%) of them were positive for the cyst in the liver and lungs, respectively. Echinococcus granulosus is actively transmitted both to humans and sheep, and CE is a zoonotic disease of public health priority in Uzbekistan.

    2009-02-01

    We propose a single, quantitative metric called the disease evaluation factor (DEF) and assess its efficiency at estimating disease burden in normal, control subjects (CTRL) and probable Alzheimer's disease (AD) patients. The study group consisted in 75 patients with a diagnosis of probable AD and 75 age-matched normal CTRL without neurological or neuropsychological deficit. We calculated a reference eigenspace of MRI appearance from reference data, in which our CTRL and probable AD subjects were projected. We then calculated the multi-dimensional hyperplane separating the CTRL and probable AD groups. The DEF was estimated via a multidimensional weighted distance of eigencoordinates for a given subject and the CTRL group mean, along salient principal components forming the separating hyperplane. We used quantile plots, Kolmogorov-Smirnov and χ2 tests to compare the DEF values and test that their distribution was normal. We used a linear discriminant test to separate CTRL from probable AD based on the DEF factor, and reached an accuracy of 87%. A quantitative biomarker in AD would act as an important surrogate marker of disease status and progression.

    Full Text Available Objective: To determine the effect of apple vinegar and balsamic vinegar on protoscolices of hydatid cyst. In this study, different concentrations of vinegar were tested at different exposure times. Methods: Liver hydatid cysts of naturally infected sheep were obtained from Arak abattoir. Protoscolices were aspirated from cyst and were transferred into a dark container and stored at 4 °C for further use. Eight concentrations of vinegars (1%, 5%, 10%, 15%, 20%, 25%, 50% and 100% v/ v were used for 1, 2, 3, 4, 5, 10, 15, 20, 30, 40, 50 and 60 min. The viability of the protoscolices was confirmed by 0.1% eosin staining test under a light microscope. Results: The scolicidal activity of apple and balsamic vinegar in concentration of ≥50% was 100%. The scolicidal activity of vinegar was dose dependent and also time dependent. Therefore, by increasing the exposure time as well as increasing the concentration of vinegar, the mortality rate increased. Conclusions: The results of our study show that vinegar has scolicidal activity and its activity is related to the concentration and exposure time.

    Hydatid cyst is the larval stage of the tapeworm Echinococcus granulosus. Hydatid cyst fluid, cyst membrane and Protoscolices, contain a complex mixture of antigens that can induce immune responses in the host. Anti-cancer properties of Protoscolices and hydatid cyst fluid has been shown. In order to identify antigens of hydatid cyst fluid that have anti-cancer effect, in this study production of monoclonal antibodies against one of the hydatid cyst fluid band (40KDa) has been investigated. There are many published patents about applications of monoclonal antibodies. In this experimental study, 40KDa band of hydatid cyst fluid that has cross reaction with sera of patients with breast cancer was used as antigen. A group of mice were immunized with this antigen, and then their spleen cells were extracted and fused with SP2 cells. Monoclonal antibodies production was checked in wells with signs of cell growth using ELISA and western blotting. The reaction of the produced monoclonal antibodies with breast cancer cells was tested using flow cytometry method. Finally, effect of the monoclonal antibodies on growth of breast cancer cells was investigated in vitro. The results of this study showed that in the first plate antibody against 40KDa was detected in several wells. In the second plate monoclonal antibodies with high titer was detected in one well. The produced monoclonal antibodies reacted with the surface of breast cancer cells. However, they had no significant effect on growth of breast cancer cells in culture medium. Monoclonal antibodies against hydatid cyst fluid 40KDa band were produced. These antibodies reacted with the surface of breast cancer cells but had no significant effect on growth of these cells.

    Full Text Available Background: Echinococcosis/hydatidosis is considered endemic in Mauritania. The aim of this study is to present an epidemiological study on the echinococcosis in man and animals in the Nouakchott region. Methods: The internal organs from livestock carcasses were inspected for research of hydatid cysts. The hydatid fluid was examined for research of the protoscoleces. Dogs were necropsied for the collect of Echinococcus granulosus.Results: In the Nouakchott Hospital, 24 surgical operation of human hydatid cysts have been per­formed, out of which 50% were localised in the lung, 33% in the liver and 17% elsewhere. Then, the incidence rate would be of 1.2% per 100 000 inhabitants in Mauritania. In the dog, the prevalence rate is 14%. The average number of E. granulosus on the whole dogs is 172 and 1227 on the positive dogs. Concerning the livestock, hydatid cysts found in 30.1% of the dromedary, 5.5% of the cattle and 6.5 of the sheep. The fertility rate of hydatid cysts in humans (75% and camels (76% was significantly higher than that of sheep (24% and cattle (23% (P<0.0001. Hydatid infestation is characterized globally by the dominance of pulmonary localiza­tions in hu­mans (50% and camels (72.7% and in the liver in sheep (76.1% and cattle (82.3%.Conclusion: The differences between prevalence rates, the fertility of hydatid cysts and diversity sites localization observed in humans and camels of one hand and the sheep and cattle on the other hand, depends possibly the strain(s diversity of E. granulosus.

    This study evaluates the feasibility of using high intensity focused ultrasound (HIFU) for the treatment of hydatid cysts of the liver. HIFU ablation was carried out in 62 patients with echinococcosis of the liver. The mean age of patients was 40.76±14.84 (range: 17-72 years). The effectiveness of the treatment was monitored in real-time by changes in the gray-scale, and by morphological studies, computed tomography, magnetic resonance imaging, and ultrasound. Criteria for evaluating the effectiveness of treatment in real time were outlines. Cytomorphological picture of destructive changes of parasitic elements was presented as well. Loss of embryonic elements of the parasite was observed at the subcellular level after HIFU-ablation and underlines the effectiveness of HIFU. Copyright © 2015. Published by Elsevier B.V.

    Full Text Available Background: Hepatic hydatid disease (HHD is a parasitic zoonosis caused by larval stage of Echinococcus tape worm. In addition to environmental factors, genetic constitution of hosts seems to play a crucial role in acquiring the infection and developing disease. Aims: This study was carried out to investigate the association of HLA-class I and class II (A, B, DR and DQ alleles with HHD by genotyping in Iraqi patients, as well as to provide information about genotypes that confer susceptibility or resistance to develop the disease. Materials and Methods: Twenty patients with HHD, their age range (20-50 years and 20 healthy controls their ages were matched with the patients were enrolled in this study. Blood was collected from patients and controls, DNA was extracted from blood samples, and then HLA-class I and class II genotyping was performed by polymerase chain reaction-sequence specific oligonucleotide probes (PCR-SSO. Results: The present findings showed that frequencies of HLA-A*32 (65%; P=0.011, DRB1*11 (60%; P=0.004 and DQB1*03 (70%; P=0.007 alleles are significantly higher in patients than controls, while the frequency of DRB1*04 was significantly decreased in patients when compared to controls (25% vs. 75%; P=0.002. Furthermore, the current study could not observe significant differences in the frequencies of HLA-B alleles between patients and controls. Conclusions: We concluded that HLA-A*32, DRB1*11 and DQB1*03 alleles might contribute to the increased susceptibility to HHD and DRB1*04 could be a protective marker against the disease.

    2014-10-01

    Full Text Available Introduction: A hydatid cyst of the head and neck is a very rare condition, even in areas where Echinococcus infestation is endemic.   Case Report: We report a rare case of primary hydatid cyst of the right maxillary sinus in a 40-year-old man. The initial diagnosis of the presence of a cystic mass was the result of physical examination and computed tomography (CT scan. We resected the cystic mass using the Caldwell-Luc procedure. A definitive diagnosis was confirmed by postoperative histopathologic examination.   Conclusion: Hydatid cyst of the maxillary sinus is an extremely rare presentation. However, this condition should be considered in differential diagnosis of cystic lesions of the maxillary sinus.

    Full Text Available Abstract Background Echinococcosis rates vary in different parts of the world. Italy is regarded as a middle to high risk country with over 1,000 cases requiring surgery each year. Liver (45–75% and lung (10–50% are the most frequent locations of this parasitosis. Case presentation The authors report a clinical case of a 62 year old woman, admitted to hospital with left flank pain. Plain radiographs of the abdomen, ultrasound, CT and MRI scans were performed and the presence of a 3-cm lesion of the left adrenal gland was demonstrated. A diagnosis of hydatid cyst was made. The patient underwent transabdominal laparoscopic left adrenalectomy. Histopathological examination confirmed the presence of a hydatid cyst in the left adrenal gland. Conclusion A hydatid cyst was correctly diagnosed on the basis of radiologic findings. The uncomplicated cyst was successfully resected using a laparoscopic approach. The pathological features of this case are presented in this paper.

    Full Text Available Giant pulmonary hydatid cyst is usually encountered in adolescents and children who are older than 10 years. A relatively higher elasticity of the lung tissue allows rapid growth of cysts. We present a case of a 15-year-old male who was admitted with complaint of frequent and persistent dry cough for over a month. Computed tomographic scan revealed a giant cyst with thick enhancing rim and an "air bubble" sign. Diagnosis of giant hydatid cyst was confirmed by surgery and histopathological examination.

    Full Text Available Although bone involvement associated with cyst hydatid is rarely seen, it can cause unintended results such as high recurrence rate, infection, sepsis, or amputation of relevant extremity. Because of this reason, its treatment is difficult and disputed. In the case of bifocal bone cyst hydatid in right femur, along with albendazole treatment, result of resecting cyst surgically and its treatment with teicoplanin with added bone cement is given. In conclusion, since the offered treatment method both supports bone in terms of mechanical aspect and also can prevent secondary infection, the method is thought to be a good and safe treatment approach.

    Chronic disease management has been a rapidly growing entity in the 21st century as a strategy for managing chronic illnesses in large populations. However, experience has shown that disease management programs have not been able to demonstrate their financial value. The objectives of disease management programs are to create quality benchmarks, such as principles and guidelines, and to establish a uniform set of metrics and a standardized methodology for evaluating them. In order to illuminate the essence of disease management and its components, as well as the complexity and the problematic nature of performing economic calculations of their profitability and value, we collected data from several reports that dealt with the economic intervention of disease management programs. The disease management economic evaluation is composed of a series of steps, including the following major categories: data/information technology, information generation, assessment/recommendations, actionable customer plans, and program assessment/reassessment. We demonstrate the elements necessary for economic analysis. Disease management is one of the most innovative tools in the managed care environment and is still in the process of being defined. Therefore, objectives should include the creation of quality measures, such as principles and guidelines, and the establishment of a uniform set of metrics and a standardized methodology for evaluating them.

    Computed Tomography (CT) plays an important diagnostic role in patients with sinonasal diseases and determines the treatment. The CT images clearly show fine structural architecture of bony anatomy thereby determining various anatomical variation, extent of disease and characterization of various inflammatory, benign and malignant sinonasal diseases. To evaluate sensitivity and specificity of CT in diagnosis of sinonasal diseases and to characterise the benign and malignant lesions with the help of various CT parameters. Also, to correlate findings of CT with histo-pathological and diagnostic nasal endoscopy/ Functional Endoscopic Sinus Surgery (FESS) findings. In this hospital based prospective study 175 patients with symptomatic sinonasal diseases were evaluated by clinical diagnosis and 16 slice Multi Detector Computed Tomography (MDCT). The details of findings of nasal endoscopy, Functional Endoscopic Sinus Surgery (FESS), histopathological examination and fungal culture were collected in all those cases where those investigations were done. All those findings were correlated with CT findings and statistical analysis was done by using Test statistics (sensitivity, specificity, Positive Predictive Value (PPV), Negative Predictive Value (NPV) and accuracy), Chi-Square test and Z-test for single proportions. Software used in the analysis was SPSS 17.0 version and graph pad prism 6.0 version and p evaluating various congenital, inflammatory, benign and malignant pathologies and associated complications thereby planning the further management of the patient. CT is the best modality of choice for evaluating the bone erosion or destruction. The potential pitfalls to differentiate on CT are fungal sinusitis and dense secretions.

    Full Text Available Bilateral hydatid cyst of lung in a child is a challenge to anaesthesiologist. The benefits of one lung versus two lung ventilation is still a question. A 9-yr-old male child presented with respiratory distress. The chest X-ray showed the presence of two cysts bilaterally in the lung fields. A possibility of bilateral hydatid cyst in lung was considered. The child was taken up for emergency single stage bilateral thoracotomy under general anaesthesia. Two lung ventilation technique was used. Postoperatively the child was kept on controlled ventilation in the paediatric intensive care unit. The child was weaned off from ventilatory support and extubated 48 hours after the surgery.

    Full Text Available Introduction & Objectives: Zoonotic parasites are large groups of zoonoses among which the most important are hydatid cyst, liver trematodes and sarcocystis.These zoonoses are of considerable importance regarding both human health and economy. The objective of this study was to determine the prevalence of tissue zoonotic parasites and their epidemiologic status in Hamadan and to estimate the health and medical burden they impose on the society.Materials & Methods: In this cross sectional study, viscera (including liver, lung, kidney, heart,… and muscles of 2590 sheep, 420 cattle, and 490 goats were macroscopically inspected for hydatid cysts, liver flukes, cysticercus , and microscopically (for Sarcocystis in the Hamadan abattoir. The data were presented by descriptive tables and analyzed by 2 statistical test. Results: The infection rate for hydatid cyst, Fasciola, Dicrocoelium and Sarcocystis were found 12.3%, 4.9%, 6.5%, and 5.5% respectively. The high infection rates for hydatid cyst and Fasciola were found in cattle (16.2% and 9.5% and for Dicrocoelium and Sarcocystis were found in sheep (6.9%. Infection rate of lungs was higher (41.2% than liver (36.6% and liver and lung simultaneously were 22.2% in the infected animals. Infection to Sarcocystis and Cysticercus were not found in the cattle. Conclusion: This study indicated that infection rate of tissue zoonotic parasites are relatively high in the domestic animals of Hamadan , however, the rate is lower in comparison to the previous studies. These parasites had imposed considerable economic burden on the society through reduction in the dairy production and increased the risk of infection in the population as well.

    Twenty patients with hydatid cyst of the dome of the liver are presented. In ten there were significant associated intrathoracic complications including pleural effusion, pleural empyema, erosion through the diaphragm into lung, various degrees of pneumonitis or pulmonary abscess, or severe destruction of both diaphragm and right lower pulmonary lobe. Bronchobiliary fistula was demonstrated at operation in five patients. Four patients had obstructive jaundice due to intrabiliary rupture of a liver hydatid. In 19 patients the cysts in the right lobe of the liver were evacuated through a right thoracotomy and incision of the diaphragm. In four of these, additional pulmonary resection was carried out. In one patient with left pleural empyema, tube drainage followed by rib resection was instituted. Two patients had common duct drainage for relief of obstructive jaundice. In 13 patients the ectocyst cavity was drained; in seven it was filled with saline and closed. One patient required evacuation and open packing of the right upper quadrant and lower right hemithorax. Thoracotomy is mandatory in patients with hydatid cyst of the dome of the liver for easier approach to the cyst and for management of coexisting intrathoracic complications.

    2001-12-01

    Full Text Available Introduction: Operation is the most common treatment for hydatid cysts. However, operation would be useless in some patients with diffuse organ involvement, special anatomic spaces or poor general conditions. So, drug therapy is considered in some studies. Albendazole is a benzimidazole derivation can gain high plasma level. It absorbed quickly after oral intake and most of it metabolized to Sulfoxide. Methods: Ten randomly selected patients with 39 hydatid cysts in different organs were treated by albendazole. Patients received 10-15 mg/kg/day of albendazole in two different divided doses for 1-4 periods of 30 days duration. Periodic clinical and paraclinical examinations were done. The cysts were in the liver, lung, spleen, peritoneum, pelvis, pericardium and chest wall. Results: Except for one cyst in lung and two in abdomen which therapeutic results have not clarified, all of the cysts died. Drug systemic side effects were negligible. Patients had good tolerance to it. Local complication such as inflamation, tenderness and rupture of cyst were the main side effects. Discussion: It is recommende to pay more attention to drug therapy in management of hydatid cyst. It is helpful for complicated cases that we cant operate them.

    Full Text Available Introduction: The Parkinson disease can be among the multiple causes of alterations in the physical equilibrium. Accordingly, this study has the objective to evaluate Parkinson patients' physical equilibrium. Method: Potential study in which 12 Parkinson individuals were evaluated by way of tests of static and dynamic equilibrium, dynamic posturography and vectoelectronystagmograph. To compare the dynamic posturography results a group of gauged control was used. Results: Alterations in Romberg-Barré, Unterberger and Walk tests were found. The vestibular exam revealed 06 normal cases, 04 central vestibular syndrome and 02 cases of peripheral vestibular syndrome. In the dynamic posturography, an equilibrium alteration has been verified, when compared to the control group in all Sensorial Organization Tests, in average and in the utilization of vestibular system. Conclusion: Parkinson patients present a physical equilibrium alteration. The dynamic posturography was more sensitive to detect the equilibrium alterations than vectoelectronystagmograph.

    Background Our aim was the presentation of a case with clinico-radiologic findings compatible with ruptured echinococcus cyst that was not finally confirmed. Case presentation A 35-year-old female patient, who was evaluated previously at another hospital, because of recurrent episodes of pleurodynia, severe epigastric pain, vomiting and constipation during the last week is presented. The chest radiograph revealed a cyst which contains air in the left lower lung field. From her past medical history the patient reported a serious car-accident a year ago, for which she was admitted to ICU for two months. Laboratory testing revealed leukocytosis. An urgent CT scan of the chest and abdomen revealed a cyst in the left lower lobe of the lung containing a freely floating endocyst (the “water-lily sign”). This “water-lily” or “meniscus” sign denoting the entrance of air between the laminated membrane and the pericyst through a bronchopericystic fistula is observed as a thin, radiolucent crescent in the upper part of the cyst on plain radiography. The ultrasound examination revealed no evidence of rupture of the cavity within the abdomen or any hepatic involvement. Emergency gastroscopy followed, in which stomach contents were not allowed to complete the examination. The patient underwent emergency thoracic exploration. At operation we found that the cyst was a pseudo-cyst as it was a part of the stomach which had slid into the thorax. The fibrin-necrotic lesion of the left hemidiaphragm as a result of past accident of the patient gave to the upper part of the stomach the opportunity to escape from the abdomen into the thorax. This part was finally winding through fibrin lesions of hemidiaphragm, engulfed therein food and gastric juice and gave the described clinical picture. Conclusions This is a rare case of post-traumatic complication of the hemidiaphragm that resembles the water-lily sign, which is seen almost exclusively in hydatid infection, when there is

    A 44-year-old patient presented with two-year history of (R) lumbar pain. There was a strong history of childhood animals' contact, including dogs. A brother had multiple hydatid cysts requiring surgery. Initial ultrasound showed a large (R) adrenal mass measuring 10 × 9 × 8 cm. Subsequent CT scan confirmed a heavily calcified cyst in the (R) adrenal gland. Hormonal studies were normal. He had an uneventful course following a total adrenalectomy. Isolated adrenal hydatid is extremely rare with an incidence of less than 0.5%; however, the diagnosis should always be suspected in all patients from an endemic area presenting with an adrenal cystic mass.

    Claudia Irene Menghi

    Full Text Available Hydatidosis is a parasitic infection caused by the tapeworm larva of Echinococcus spp. Its relevance lies in its wide distribution, great number of clinical cases and outstanding morbility. Hydatid infection of the orbit comprises far less than 1% of the total incidence. This is a case of a patient from Argentina complaining of a two-week evolution proptosis of the right eye. A microscopic examination revealed the presence of protoscolices of Echinococcus spp. in the fluid obtained during the surgical proceedings. The patient was treated with oral albendazole. To our knowledge, this is the first case of occular hydatidosis diagnosed in the city of Buenos Aires, Argentina.

    2003-01-01

    Full Text Available Complications of the hydatid cyst of the liver on bile ducts appear in 5-25% representing almost two third of all complications of the hydatid liver cysts. Fortunately a damage to the bile ducts causes only an infection of the cyst usually without major consequences. More serious complications such as cholangitis and deep obstructive jaundice are much rarer. The defect of the bile duct usually is a periferal one. Damage to the major ducts are rarer and those on the confluence of hepatic ducts itself are the rarity. In that case biliary reconstruction may be a serious chalenge. The authors present a 23 year-old man in whom a centrally localised hydatid cyst made a major damage of the confluence of all three hepatic ducts causing deep obstructive jaundice. After standard procedure for hydatid cyst an intracavital mucosa to mucosa hepaticoje-junostomy was carried out with excellent success. More then six years after surgery the patient stayed symptom-free with bilirubin and alkaline phosphatase within normal limits.

    Hydatid cyst of the liver remains a serious public health problem in Tunisia. This benign affection can sometimes cause fatal complications such as cyst rupture into the thorax. We report 5 cases of patients who experienced intrathoracic rupture of hydatic cyst of liver. There were four rural women and an urban man. Patients were between 60 and 75 years of age. We present 2 cases of cyst rupture into pleura, 3 cases of hydatid bronchial fistula and 3 cases of biliothoracic fistulas. Surgical treatment was performed by laparotomy in 3 cases, thoracic approach in one case and by thoracoabdominal approach in the other case. We deplore one case of early death by hemorrhagic shock. Authors emphasize the complexity of the management of hydatic cyst of liver ruptured into the thorax. Surgical treatment remains responsible of high perioperative morbidity and mortality. Early diagnostic and improvement of reanimation measures are important to improve the prognosis of this serious complication. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Full Text Available Objective. Although several therapeutic strategies have proven to be effective for hydatid cyst of liver, but surgery is still the most common therapy despite its morbidity and mortality. Furthermore, a variety of technique has been recommended for managing the residual cavity after cystectomy. We report here a new technical method for the reconstruction of hydatid cyst residual cavity with using overlapping flaps of liver edges (Vest over Pant. Methods. In this technique after removing the cyst, the edges of one side of cyst cavity were sutured to the base of the cavity using three to four mattress sutures, and edges of other side of liver was overlapped on the dorsal part of previous layer using four to five mattress sutures. Therefore residual cavity dead space was obliterated with two surfaces of cavity. Results. Fifty males were treated by our method. The average cyst volume was 423±110 mL. There was no intraabdominal sepsis, bile leakage, or hepatic necrosis. In follow-up ultrasound study, residual cavities were disappeared one month after operation. Conclusion. Overlapping flaps of liver edges (Vest over Pant provides easy, safe closure of cyst with preservation of the liver anatomy.

    Disease management has emerged as a new strategy to enhance quality of care for patients suffering from chronic conditions, and to control healthcare costs. So far, however, the effects of this strategy remain unclear. Although current models define the concept of disease management, they do not provide a systematic development or an explanatory theory of how disease management affects the outcomes of care. The objective of this paper is to present a framework for valid evaluation of disease-management initiatives. The evaluation model is built on two pillars of disease management: patient-related and professional-directed interventions. The effectiveness of these interventions is thought to be affected by the organisational design of the healthcare system. Disease management requires a multifaceted approach; hence disease-management programme evaluations should focus on the effects of multiple interventions, namely patient-related, professional-directed and organisational interventions. The framework has been built upon the conceptualisation of these disease-management interventions. Analysis of the underlying mechanisms of these interventions revealed that learning and behavioural theories support the core assumptions of disease management. The evaluation model can be used to identify the components of disease-management programmes and the mechanisms behind them, making valid comparison feasible. In addition, this model links the programme interventions to indicators that can be used to evaluate the disease-management programme. Consistent use of this framework will enable comparisons among disease-management programmes and outcomes in evaluation research.

    Refsum disease is a rare metabolic disorder, which is characterized by the accumulation of phytanic acid in the blood and tissues, including the brain. A variant of this condition that occurs in young children is called infantile Refsum disease. The MRI findings of symmetrical signal change involving the corticospinal tracts, cerebellar dentate nuclei, and corpus callosum are characteristic. We report the serial MRI findings of a child with this rare metabolic disorder. (orig.)

    One-lung ventilation was used in 13 children, undergoing surgical excision of pulmonary hydatid cysts. Five had right-sided pulmonary cysts and eight had left cysts. An ordinary cuffed tracheal tube was introduced to the main bronchus of the healthy side. One-lung ventilation using 1-2% halothane in oxygen produced PaO2 values of 12.6-33.3 KPa and PaCO2 values of 4-6kPa. After operation there was a high frequency of right upper lobe collapse in cases of selective right bronchial intubation, but this cleared completely within 3-4 days. The technique proved to be a simple and effective method of isolating and ventilating the healthy lung.

    Full Text Available Abstract Background Incidence of liver hydatid cyst (LHC rupture ranged 15%-40% of all cases and most of them concern the bile duct tree. Patients with biliocystic communication (BCC had specific clinic and therapeutic aspect. The purpose of this study was to determine witch patients with LHC may develop BCC using classification and regression tree (CART analysis Methods A retrospective study of 672 patients with liver hydatid cyst treated at the surgery department "A" at Ibn Sina University Hospital, Rabat Morocco. Four-teen risk factors for BCC occurrence were entered into CART analysis to build an algorithm that can predict at the best way the occurrence of BCC. Results Incidence of BCC was 24.5%. Subgroups with high risk were patients with jaundice and thick pericyst risk at 73.2% and patients with thick pericyst, with no jaundice 36.5 years and younger with no past history of LHC risk at 40.5%. Our developed CART model has sensitivity at 39.6%, specificity at 93.3%, positive predictive value at 65.6%, a negative predictive value at 82.6% and accuracy of good classification at 80.1%. Discriminating ability of the model was good 82%. Conclusion we developed a simple classification tool to identify LHC patients with high risk BCC during a routine clinic visit (only on clinical history and examination followed by an ultrasonography. Predictive factors were based on pericyst aspect, jaundice, age, past history of liver hydatidosis and morphological Gharbi cyst aspect. We think that this classification can be useful with efficacy to direct patients at appropriated medical struct's.

    Full Text Available A 44-year-old patient presented with two-year history of (R lumbar pain. There was a strong history of childhood animals’ contact, including dogs. A brother had multiple hydatid cysts requiring surgery. Initial ultrasound showed a large (R adrenal mass measuring 10×9×8 cm. Subsequent CT scan confirmed a heavily calcified cyst in the (R adrenal gland. Hormonal studies were normal. He had an uneventful course following a total adrenalectomy. Isolated adrenal hydatid is extremely rare with an incidence of less than 0.5%; however, the diagnosis should always be suspected in all patients from an endemic area presenting with an adrenal cystic mass.

    On 3 July 2009, new law pertaining to occupational diseases (ODs) became effective in Poland. The article presents opinions of the representatives of the 1st degree ODs certification entities and sanitary inspectorates on the changes in OD) law and the problems that may cause difficulties and/or certification errors. A questionnaire study was performed covering representatives of 20 voivodeship occupational medicine centers and 40 national district sanitary inspectorates. We received 57 completed questionnaires which were analyzed. Positive opinions were expressed on changes in procedures on reporting suspected occupational diseases (50%), keeping time limits for diagnosing ODs (89.2%), and changes pertaining to entities responsible for certifying infectious ODs (92.9%). A large group of respondents (66.7%) was in favor of conducting jointly an occupational exposure risk analysis by occupational medicine physicians and occupational health and safety practitioners and/or sanitary inspectors. One-third of the respondents declared that changes in the list of ODs had no influence on the certification procedure. New law has improved the existing procedure of ODs certification. There is a need to elaborate detailed diagnostic guidelines on and criteria for ODs identification and recognition. A panel of experts should be established by the Ministry of Health to track the latest advancements in medicine and to update the list of OD)s. Conducting jointly an occupational exposure risk analysis by occupational medicine physicians and occupational health and safety practitioners and/or sanitary inspectors should become a standard.

    To assess the prevalence of renal abnormalities in ragdoll cats. Ragdoll breeders often warn clients to watch for future renal problems, mainly due to chronic interstitial nephritis and polycystic kidney disease. Therefore, ragdoll screening by abdominal ultrasonography, measurement of serum creatinine and urea concentrations and genetic testing is often performed without documented scientific evidence of increased risk of renal disease. Retrospective evaluation of ragdoll screening for renal disease at one institution over an eight-year period. Renal ultrasonography was performed in 244 healthy ragdoll cats. Seven cats were positive for polycystic kidney disease, 21 were suspected to have chronic kidney disease, 8 had abnormalities of unknown significance and 2 cats had only one visible kidney. Cats suspected to have chronic kidney disease were significantly older and had significantly higher serum urea and creatinine concentrations than cats with normal renal ultrasonography. All 125 genetically tested cats were negative for polycystic kidney disease. However, only one of the seven ultrasonographically positive cats underwent genetic testing for polycystic kidney disease. Ultrasonographic findings compatible with chronic kidney disease were observed in almost 10% of cats, and polycystic kidney disease occurred at a low prevalence (cats are predisposed to chronic kidney disease. © 2012 British Small Animal Veterinary Association.

    Disease management programmes are heterogeneous in nature and often lack a theoretical basis. An evaluation model has been developed in which theoretically driven inquiries link disease management interventions to outcomes. The aim of this study is to methodically evaluate the impact of a disease management programme for patients with chronic obstructive pulmonary disease (COPD) on process, intermediate and final outcomes of care in a general practice setting. A quasi-experimental research was performed with 12-months follow-up of 189 COPD patients in primary care in the Netherlands. The programme included patient education, protocolised assessment and treatment of COPD, structural follow-up and coordination by practice nurses at 3, 6 and 12 months. Data on intermediate outcomes (knowledge, psychosocial mediators, self-efficacy and behaviour) and final outcomes (dyspnoea, quality of life, measured by the CRQ and CCQ, and patient experiences) were obtained from questionnaires and electronic registries. Implementation of the programme was associated with significant improvements in dyspnoea (p model showed associations between significantly improved intermediate outcomes and improvements in quality of life and dyspnoea. The application of a theory-driven model enhances the design and evaluation of disease management programmes aimed at improving health outcomes. This study supports the notion that a theoretical approach strengthens the evaluation designs of complex interventions. Moreover, it provides prudent evidence that the implementation of COPD disease management programmes can positively influence outcomes of care.

    Between 1990 and 2006 in the III-rd Surgical Clinic Cluj-Napoca, 366 pacients with hepatic hydatid cyst were admitted and underwent surgery; 81 (22.13%) of them, who had a cyst-biliary comunication, were retrospectively reviewed: 52 (64.2%) had an occult communications and 29 (35.8%) had a frank intrabiliary rupture. The sex ratio was M/F=46/35 with a mean age of 44.5 years and with ages between 17 and 73 years. Choledochotomy, evacuation of parasitic material and lavage of the CBP were performed in all patients with frank intrabiliary rupture. In 25 patients, partial pericystectomy and choledochoduodenostomy/T-tube drainage of CBP was performed. Internal drainage by a Roux-en-Y pericystectojejunostomy and biliodigestive anastomosis was carried out in 2 patients, while other two patients underwent external drainage of cystic cavity and T-tube drainage of CBP. 15 patients (51.7%) had postoperative external bile leaks (fistulas). Occult communications were managed by partial pericystectomy +/- narrowing of the residual cavity (capitonage with an omentum flap or invagination of the fibrosis capsule margins into the cavity) in 35 patients (67.3%) while in 10 patients (19.2%) internal drainage by a Roux-en-Y pericystectojejunostomy was carried out. Regional resection of the liver was performed in 4 cases (7.7%) and external drainage of residual cavity in 3 patients (5.7%). 13 patients (25%) had postoperative external bile leaks (fistulas). The mean postoperative hospitalisation was 20 days with the range 5-85 days. The mortality rate was 2.4% (2 patients): one died due to septicemia and MOFS and the other due to pulmonary thromboembolism. Postoperative bile leaks (fistulas) fallowing conservative surgery of ruptured hydatid hepatic cyst into the biliary tract are not rare regardless of the type of rupture (frank or occult). Although the opening of the biliary duct is sutured, the risk of biliary fistulas is not clearly corelated with this approach; in such cases

    Preoperative evaluation of infectious diseases in patients for elective and non-elective surgery is important for the anesthesiologists not only to rule out the patient's state of illness, but also to prevent transmission of infectious diseases in healthcare settings. To prevent transmission of infectious diseases in healthcare settings, Center for Disease Control published guidelines that consist of standard precaution and transmission-based precautions. In the face of exposure to known infectious diseases, certain post exposure prophylaxis has been established, especially against exposure to human immunodeficiency virus and hepatitis B virus. There are also growing interests in perioperative prevention of surgical site infection, since World Health Organization has published surgical safety checklist with the slogan "Safe surgery saves life". Anesthesiologists need to have knowledge on the prevention of surgical site infection especially on antibiotic prophylaxis, because it starts in the operating room.

    Full Text Available Mammary and extramammary Paget′s diseases are rare neoplasms of epidermis and mucosal epithelium. Due to their nonspecific and variable clinical view, they have differential diagnosis with eczema, melanoma, Bowen′s disease, etc. To the best of our knowledge, no such study has been performed in Iran regarding the prevalence, clinical aspects, underlying disease and pathological characteristics of these two diseases. In this study, we have evaluated the clinical and histopathological aspects of this disorder. Materials and Methods: In this retrospective study, all Paget′s biopsied samples referred to the Pathology Department of Imam-Reza hospital, Mashhad, since 1984 till 2004 were evaluated. Collected data were analyzed by descriptive statistical methods. Results: Among 98925 specimens, there were 29 cases of Paget′s disease. All cases were married women suffering from mammary Paget. The mean age was 53 ± 11 years. Left and right breast involvement was observed in 17 and 12 cases, all unilateral. The most common clinical view was ulcerated (27% and then erythematosus exudative plaques. More than 50% of patients were symptomatic. Most common symptoms were itching, pain and burning. The exclusive underlying pathological diagnosis was ductal carcinoma (55%. Discussion: In most cases, the clinical view of mammary Paget′s disease was helpful. Unilateral ulcerated plaque was the most common clinical sign. Majority of the accompanying pathology was ductal carcinoma. We had no cases of extramammary Paget′s disease in our study.

    Pancreatic fistula (PF) is an important complication that may develop during intra-abdominal surgeries and following distal pancreas trauma. In the early period, drainage from the surgical site and increased amylase production based on the biochemical examination of the drainage fluid are the factors for diagnosis. In contrast, in association with fluid collected from the surgical site, intra-abdominal abscess and high fever may lead to the diagnosis in the late period. Endoscopic retrograde cholangiopancreatography (ERCP) for the treatment of intra-abdominal fluid collection after PF and intra-abdominal percutaneous stent placement as well as the placement of a pancreatic stent in the pancreatic channel may be alternative methods to stop drainage. However, the complete resolution of fluid drainage may take months. In our case, drainage from the pancreatic fistula area took longer to resolve than the periods previously reported in the English literature. The tail of the pancreas can be injured during the extraction of especially aggressive and metastatic masses from organs near to the distal pancreas. Injury to the tail of the pancreas can also occur during the extraction of benign-like renal hydatid cysts and/or malignant left kidney masses. However, PF can be treated with noninvasive methods, such as percutaneous treatment and ERCP. PMID:26328082

    Full Text Available Surgery is still the main treatment in hydatidosis caused by Echinococcus, which is a global health problem in human and animals. So, there is need for some natural protoscolicidal agents for instillation to prevent their reoccurrence at therapeutic doses. In this present investigation, anticestodal activity of one of the endophytic fungi Pestalotiopsis sp. from Neem plant was observed on protoscoleces of hydatid cysts of Echinococcus granulosus. Viability of protoscoleces was confirmed by 0.1% aqueous eosin red stain method, where mortality was observed at different concentrations with respect to time. An average anticestodal activity was observed with different endophytic fungal strains, that is, Nigrospora (479 ± 2.9, Colletotrichum (469 ± 25.8, Fusarium (355 ± 14.5, and Chaetomium (332 ± 28.3 showing 64 to 70% protoscolicidal activity, except Pestalotiopsis sp. (581 ± 15.0, which showed promising scolicidal activity up to 97% mortality just within 30 min of incubation. These species showed significant reduction in viability of protoscoleces. This is the first report on the scolicidal activity of endophytic Pestalotiopsis sp. We conclude that ultrastructural changes in protoscoleces were due to endophytic extract suggesting that there may be some bioactive compounds that have selective action on the tegument layer of protoscoleces. As compared with that of standard drug used, endophytic species of Neem plant shows significant anticestodal activity.

    1975-12-11

    Healthy germinal membranes of hydatid cysts from lungs of human and bovine sources were dissected and isolated for histochemical and histoenzymatic research. These techniques were performed in frozen sections and pieces of the whole membrane. Enzymatic research showed that the germinal membrane presents highly differentiated metabolic areas. These areas were topographically related with the origin and insertion of brood capsules, having differentiated structures for metabolic interchange with scolices. Taking our data into account it may be suggested that this functional differentiation could be transitory and variable for all the membrane surface. The accumulation of lipids and enzymes such as simple estarase, lipase, beta-HDH, alpha-GDH and NADPH-reductase in those areas, suggests that lipids are not a simple excretory product. This distribution probably implies that lipid metabolism or its resultant products are important in development and growth of scolices. In that sense other authors' findings and hypothesis about the possible existence of an endocrine system of the parasite, are considered. This idea being demonstrated in further researches, the lipid metabolic pathways shall bring a good pharmacological approach to the interference with parasite development.

    Full Text Available Hydatidosis is characterized by the long-term coexistence of larva Echinococcus granulosus and its host without effective rejection. Previous studies demonstrated nitric oxide (NO production (in vivo and in vitro during hydatidosis. In this study, we investigated the direct in vitro effects of NO species: nitrite (NO2−, nitrate (NO3− and peroxynitrite (ONOO− on protoscolices (PSCs viability and hydatid cyst layers integrity for 24 hours and 48 hours. Our results showed protoscolicidal activity of NO2− and ONOO− 24 hours and 3 hours after treatment with 320 μM and 80 μM respectively. Degenerative effects were observed on germinal and laminated layers. The comparison of the in vitro effects of NO species on the PSCs viability indicated that ONOO− is more cytotoxic than NO2−. In contrast, NO3− has no effect. These results suggest possible involvement of NO2− and ONOO− in antihydatic action and point the efficacy of these metabolites as scolicidal agents.

Methods Alzheimer's disease, donepezil, rivastigmine, galantamine, memantine, rosiglitazone, etc. were defined as retrieval words. PubMed, Cochrane Library, Wanfang Data and China National Knowledge Infrastructure (CNKI databases were used with applying of manual searching. Systematic reviews, randomized controlled trials (RCT, controlled clinical trials and case-observation studies were collected and evaluated by Jadad Scale. Results After screening, 33 selected resources included 14 systematic reviews, 14 randomized controlled trials, 4 controlled clinical trials and 1 case-observation study. According to Jadad Scale, total 28 articles were evaluated to be high quality (12 with score 4, 10 score 5, 6 score 7, and 5 were low quality with score 3. It was summarized as follows: 1 Alzheimer's disease is a progressive neurodegenerative disease for which no cure exists. To date, only symptomatic treatments with cholinesterase inhibitors (donepezil, rivastigmine, galantamine and an N-methyl-D-aspartate (NMDA receptor noncompetitive antagonist (memantine, are effective and well tolerated to counterbalance the neurotransmitter disturbance, but cannot limit or impact on disease progression. 2 Disease modifying drug is an potential agent, with persistent effect on slowing the progression of structural damage, and can be detected even after withdrawing the treatment. Many types of disease modifying drugs are undergoing clinical trials. Conclusions Using evidence-based medicine methods can provide best clinical evidence on Alzheimer's disease treatment. doi: 10.3969/j.issn.1672-6731.2014.03.009

    Summary Ataxia-telangiectasia (A-T) is a rare autosomal recessive disorder caused by mutations in the ATM gene, resulting in faulty repair of breakages in double-stranded DNA. The clinical phenotype is complex, and is characterized by neurologic abnormalities, immunodeficiencies, susceptibility to malignancies, recurrent sinopulmonary infections, and cutaneous abnormalities. Lung disease is common in patients with A-T and often progresses with age and neurological decline. Diseases of the respiratory system cause significant morbidity and are a frequent cause of death in the A-T population. Lung disease in this population is thought to exhibit features of one or more of the following phenotypes: recurrent sinopulmonary infections with bronchiectasis, interstitial lung disease, and lung disease associated with neurological abnormalities. Here, we review available evidence and present expert opinion on the diagnosis, evaluation, and management of lung disease in A-T, as discussed in a recent multidisciplinary workshop. Although more data are emerging on this unique population, many recommendations are made based on similarities to other more well-studied diseases. Gaps in current knowledge and areas for future research in the field of pulmonary disease in A-T are also outlined. PMID:20583220

    Forty-two patients with valvular heart diseases were studied with a third-generation computed tomographic system. The cardiac chambers (the atria and ventricles) were evaluated semiquantitatively, and valvular calcification was easily detected with computed tomography. Computed tomography was most valuable in revealing left atrial thrombi which were not identified by other diagnostic procedures in some cases.

    2001-01-01

    Evaluation of canine congenital heart disease presents a diagnostic challenge to many ultrasonographers. To assist clinicians attempting to examine these patients, an echocardiographic algorithm containing the six most common canine congenital heart diseases (i.e., patent ductus arteriosus, subaortic stenosis, pulmonic stenosis, ventricular septal defect, tricuspid dysplasia, and tetralogy of Fallot) is presented. The algorithm focuses on the underlying disease pathogenesis and the resultant changes in cardiac structure and function that can be readily identified during echocardiographic examination. Use of this algorithm provides a framework from which the ultrasonographer gains both experience and confidence in diagnosing congenital heart disease via echocardiography. This algorithm is supported by a number of still figures within the article as well as real-time echocardiographic images available for viewing at AAHA's website, www.aahanet.org.

It is caused by a parasitic platyhelminth of the genus Echinococcus. We present a patient with a fluctuating lumbar tumor in the retroperitoneal space, secondary to a hepatic cyst. The initial diagnosis was made by identification of rostellar hooks from protoscoleces in the fluid aspirated from the abscess. We herein describe the clinical manifestations, diagnosis and medical and surgical treatment of this unusual case and conclude that the development of an accurate diagnosis required a proper analysis of the patient's epidemiological history, clinical manifestations, imaging studies and laboratory tests. A multidisciplinary approach and differential diagnosis is paramount to be able to establish a cause of the disease to deliver appropriate treatment.

    The objectives were to determine the resistive index (RI) in normal cats and in cats with various renal diseases, and to evaluate the effect of age on RI. The subjects were cats that had ultrasonography (US) of the urinary tract and RI measurement at our centre between January 2003 and April 2014. Based on clinical evaluation, biochemical and haematological tests, urinalysis and US, the cats were classified as healthy or diseased. RI measurements were made from the interlobar or arcuate arteries. Data were analysed for differences between the right and the left kidney, the two sexes, different age groups in healthy cats, and between healthy and diseased cats. A total of 116 cats (68 males, 48 females) were included: 24 healthy and 92 diseased. In the healthy cats, RI (mean ± SD) differed significantly (P = 0.02) between the right kidney (0.54 ± 0.07) and the left kidney (0.59 ± 0.08). For the left kidney, RI was significantly higher in cats with chronic kidney disease (0.73 ± 0.12) and acute kidney injury (0.72 ± 0.08) (P = 0.0008). For the right kidney, RI was significantly higher in cats with chronic kidney disease (0.72 ± 0.11), acute kidney injury (0.74 ± 0.08), polycystic kidney disease (0.77 ± 0.11) and renal tumour (0.74 ± 0.001) (P cats, useful in the differential diagnosis of diffuse renal diseases. While it does not change with the age of the cat, ultrasonographers should be aware that RI may differ between the two kidneys. © ISFM and AAFP 2015.

    Although Spain is the European country with the highest Chagas disease burden, the country does not have a national control program of the disease. The purpose of this study is to evaluate the efficiency of several strategies for Chagas disease screening among Latin American residents living in Spain. The following screening strategies were evaluated: (1) non-screening; (2) screening of the Latin American pregnant women and their newborns; (3) screening also the relatives of the positive pregnant women; (4) screening also the relatives of the negative pregnant women. A cost-utility analysis was carried out to compare the four strategies from two perspectives, the societal and the Spanish National Health System (SNHS). A decision tree representing the clinical evolution of Chagas disease throughout patient's life was built. The strategies were compared through the incremental cost-utility ratio, using euros as cost measurement and quality-adjusted life years as utility measurement. A sensitivity analysis was performed to test the model parameters and their influence on the results. We found the "Non-screening" as the most expensive and less effective of the evaluated strategies, from both the societal and the SNHS perspectives. Among the screening evaluated strategies the most efficient was, from both perspectives, to extent the antenatal screening of the Latin American pregnant women and their newborns up to the relatives of the positive women. Several parameters influenced significantly on the sensitivity analyses, particularly the chronic treatment efficacy or the prevalence of Chagas disease. In conclusion, for the general Latin American immigrants living in Spain the most efficient would be to screen the Latin American mothers, their newborns and the close relatives of the mothers with a positive serology. However for higher prevalence immigrant population the most efficient intervention would be to extend the program to the close relatives of the negative

    This study attempts to demonstrate the role of computed tomography in the diagnosis of hepatic hydatid cyst rupture based on specific imaging findings and to propose combinations of the imaging findings diagnostic for specific types of rupture. Eleven patients were studied with computed tomography of the abdomen, with 4-8 mm slice thickness, after the oral administration of contrast material and intravenous contrast material in 6 cases. Based on a combination of imaging findings the types of hepatic hydatid cyst rupture were: intrabiliary rupture in 7 patients, intraperitoneal rupture in 1 patient, intrathoracic rupture in 1 patient, hepatic subcapsular rupture in 2 patients. Structural deformity of the cyst was present in all cases, combined with: dilatation of the intrahepatic bile ducts (intrabiliary rupture); intraperitoneal fluid collections with diffuse haziness and stranding of the mesenteric fat (intraperitoneal rupture); an inhomogeneous lesion in the thorax with ipsilateral pleural effusion (intrathoracic rupture); a hydatid cyst located peripherally, with discontinuity of its adjacent to the hepatic capsule wall and subcapsular fluid collection (subcapsular rupture). The imaging findings were surgically and pathologically confirmed. Using combinations of specific imaging findings we correctly diagnosed the type of hepatic hydatid cyst rupture in all cases.

  1. Evaluation of ischemic heart disease and viability by cardiac MRI

    Directory of Open Access Journals (Sweden)

    Mona Bhatia

    2014-01-01

    Full Text Available In ischemic heart disease, cardiac MRI, besides being the gold standard for evaluation of quantitative ventricular function, enables evaluation of myocardial wall thickness, T2-weighted imaging for myocardial edema and infarct quantification and transmurality. Delayed hyperenhancement sequences are highly predictive of scar formation, being associated with myocyte necrosis. The extent and transmurality of delayed hyperenhancement has prognostic implications and is inversely proportional to the degree of functional recovery after acute myocardial infarction. A greater transmural extent of infarction (eg, hyperenhancement involving >50% of the wall thickness can predict regions that are less likely to improve in function after therapy. The ultimate focus of MRI in ischemic heart disease is in diagnosis, quantification of myocardium at risk, salvageable myocardium, perfusion defects and differentiation of viable myocardium from non viable myocardium to enable prognostication.

  2. Podometry: a critical evaluation of its use in Hansen's disease

    Directory of Open Access Journals (Sweden)

    Júlia Maria D'Andréa Greve

    Full Text Available The aim of this paper is to evaluate the effectiveness of podometry to measure the pressure developed over the feet and the value of these findings to help in the prevention of the plantar neuropathic ulcer in patients bearing Hansen's disease. We evaluated 13 patients with impaired plantar pain and touch sensations and 17 normal patients. All the patients were submitted to static evaluation using the podometer. The system employed was the "Midcapteur" commercial podometer composed of a platform for acquisition of analogic data capable of registering the segmental pressures applied to the feet. These data are read by a 386 IBM/PC compatible computer that registers the graphic patterns obtained from the pressures developed and also calculates the modes of pressure distribution in the four quadrants of the foot. These data obtained by means of static podometry were compared to the clinical evaluation of pain and touch sensation of the feet in hansenian patients. The results demonstrate that podometery is an efficient method for evaluating the pressure in impaired feet in Hansen's disease and is a progression of neuropathic ulcer; it is sensitive in the identification of the spots of increased pressure in anesthetic and anomalous areas, asymmetries and in correlating the presence of ulcers with increased pressure.

    Neurovascular injury is a serious complication after surgery for Dupuytren disease. The purpose of this study was to evaluate the relationship between the cord and the neurovascular bundle ultrasonographically. We included 22 healthy volunteers and 14 Dupuytren disease patients (25 fingers) in this study. We evaluated the cord and the digital artery with high-resolution ultrasound. We first investigated the effect of the angle of metacarpophalangeal joint on the position of the radial and ulnar digital arteries in volunteers without evidence of Dupuytren disease. We compared 3 parameters of the radial and ulnar digital arteries, including differences in depth, differences in lateral shift, and the shape of the cross-section of the artery, between volunteers and patients with Dupuytren disease. None of these parameters changed with flexion of the metacarpophalangeal joint of 0°, 30°, and 60°. Digital arteries and cords could be identified ultrasonographically in all patients, and we confirmed ultrasonographic findings by operative findings in 13 fingers. We classified the fingers into 3 subgroups based on the ultrasonographic findings: type A (n = 13), in which the cord was above the artery; type B (n = 5), in which the cord was below the artery; and type C (n = 7), in which the cord was located between the radial and ulnar digital arteries. Types A, B, and C corresponded to natatory cord/abductor digiti minimi cord, spiral cord, and central cord, respectively. Comparisons among volunteers and patient subgroups showed that the difference in depth in type B patients was significantly larger than that of the other groups. When we set the cutoff point of the difference in depth to 3 mm, sensitivity and specificity to detect the spiral cord were 80% and 76%, respectively. The relationship between the neurovascular bundle and the type of Dupuytren disease cord can be evaluated by high-resolution ultrasound. Diagnostic III. Copyright © 2013 American Society for

    Gaucher disease is caused by an inherited deficiency of glucocerebrosidase that manifests with storage of glycolipids in lysosomes, particularly in macrophages. Available cell lines modeling Gaucher disease do not demonstrate lysosomal storage of glycolipids; therefore, we set out to develop two macrophage models of Gaucher disease that exhibit appropriate substrate accumulation. We used these cellular models both to investigate altered macrophage biology in Gaucher disease and to evaluate candidate drugs for its treatment. We generated and characterized monocyte-derived macrophages from 20 patients carrying different Gaucher disease mutations. In addition, we created induced pluripotent stem cell (iPSC)-derived macrophages from five fibroblast lines taken from patients with type 1 or type 2 Gaucher disease. Macrophages derived from patient monocytes or iPSCs showed reduced glucocerebrosidase activity and increased storage of glucocerebroside and glucosylsphingosine in lysosomes. These macrophages showed efficient phagocytosis of bacteria but reduced production of intracellular reactive oxygen species and impaired chemotaxis. The disease phenotype was reversed with a noninhibitory small-molecule chaperone drug that enhanced glucocerebrosidase activity in the macrophages, reduced glycolipid storage, and normalized chemotaxis and production of reactive oxygen species. Macrophages differentiated from patient monocytes or patient-derived iPSCs provide cellular models that can be used to investigate disease pathogenesis and facilitate drug development.

    Full Text Available Giorgio Ardita, Giacomo Failla, Paolo Maria Finocchiaro, Francesco Mugno, Luigi Attanasio, Salvatore Timineri, Michelangelo Maria Di SalvoCardiovascular Department, Angiology Unit, Ferrarotto Hospital, Catania, ItalyAbstract: Connective tissue diseases (CTDs are associated with increased risk of cardiovascular disease due to accelerated atherosclerosis. In patients with autoimmune disorders, in addition to traditional risk factors, an immune-mediated inflammatory process of the vasculature seems to contribute to atherogenesis. Several pathogenetic mechanisms have been proposed, including chronic inflammation and immunologic abnormalities, both able to produce vascular damage. Macrovascular atherosclerosis can be noninvasively evaluated by ultrasound measurement of carotid or femoral plaque. Subclinical atherosclerosis can be evaluated by well-established noninvasive techniques which rely on ultrasound detection of carotid intima-media thickness. Flow-mediated vasodilatation and arterial stiffness are considered markers of endothelial dysfunction and subclinical atherosclerosis, respectively, and have been recently found to be impaired early in a wide spectrum of autoimmune diseases. Carotid intima-media thickness turns out to be a leading marker of subclinical atherosclerosis, and many studies recognize its role as a predictor of future vascular events, both in non-CTD individuals and in CTD patients. In rheumatic diseases, flow-mediated dilatation and arterial stiffness prove to be strongly correlated with inflammation, disease damage index, and with subclinical atherosclerosis, although their prognostic role has not yet been conclusively shown. Systemic lupus erythematosus, rheumatoid arthritis, and likely antiphospholipid syndrome are better associated with premature and accelerated atherosclerosis. Inconclusive results were reported in systemic sclerosis.Keywords: rheumatic disease, subclinical atherosclerosis, arterial stiffness

    Full Text Available Noninvasive approaches for assessment of liver histology include routine laboratory tests and radiological evaluation. The purpose of our study was to determine the utility of a simplified scoring system based on routinely evaluated ultrasound features for the evaluation of chronic liver disease and correlate it with the histological findings. For this cross-sectional analytical study the data was collected prospectively by nonprobability purposive sampling technique. The ultrasound variables/parameters and their assigned scoring system that was a modified version adopted from published literature were evaluated. Sensitivity, specificity, positive and negative predictive values of the liver morphological score and combined score of liver morphology and sizes was determined using stage and grade as reference standard. Our results show a high sensitivity and PPV of liver morphological sonographic evaluation for the staging and grading of CLD respectively thus supporting it as a screening diagnostic strategy. Of the three liver morphology variables, specificity of liver surface evaluation was highest for the stage of fibrosis and grade of inflammation. The simplified ultrasound scoring system evaluated in our study is clinically relevant and reproducible for differentiating patients with CLD with mild or no fibrosis from moderate to severe fibrosis.

    Background. Changes in proprioception may contribute to postural instability in individuals with neurological disorders. Objectives. Evaluate proprioception in the lower limbs of patients with Parkinson's disease (PD) and the association between proprioception and cognitive ability, motor symptoms, postural instability, and disease severity. Methods. This is a cross-sectional, controlled study that evaluated proprioception in PD patients and healthy age- and sex-matched individuals. Kinetic postural proprioception of the knee was evaluated using an isokinetic dynamometer (Biodex® Multi-Joint System 4 Pro). Participants were evaluated using the Montreal Cognitive Assessment (MoCA), the Hoehn and Yahr rating scale and postural instability (pull test and stabilometric analysis), and motor function (UPDRS-III) tests. Results. A total of 40 individuals were enrolled in the study: 20 PD patients and 20 healthy controls (CG). The PD patients had higher angular errors on the proprioceptive ratings than the CG participants (p = 0.002). Oscillations of the center of pressure (p = 0.002) were higher in individuals with PD than in the controls. Proprioceptive errors in the PD patients were associated with the presence of tremors as the dominant symptom and more impaired motor performance. Conclusion. These findings show that individuals with PD have proprioceptive deficits, which are related to decreased cognitive ability and impaired motor symptoms. PMID:27672650

    Public Health Ontario (PHO) publishes various infectious disease surveillance reports, but none have yet been formally evaluated. PHO evaluated its monthly and annual infectious disease surveillance reports to assess public health stakeholders' current perception of the products and to develop recommendations for improving future products. An evaluation consisting of an online survey and a review of public Web sites of other jurisdictions with similar annual reports. For the online survey, stakeholder organizations targeted were the 36 local public health units and the Health health ministry in Ontario, Canada. Survey participants included epidemiologists, managers, directors, and other public health practitioners from participating organizations. Online survey respondents' awareness and access to the reports, their rated usefulness of reports and subsections, and suggestions for improving usefulness; timeliness of select annual reports from other jurisdictions based on the period from data described to report publication. Among 57 survey respondents, between 74% and 97% rated each report as useful; the most common use was for situational awareness. Respondents ranked timeliness as the most important attribute of surveillance reports, followed by data completeness. Among 6 annual reports reviewed, the median time to publication was 11.5 months compared with 23.2 months for PHO. Recommendations based on this evaluation have already been applied to the monthly report (eg, focusing on the most useful sections) and have become key considerations when developing future annual reports and other surveillance reporting tools (eg, need to provide more timely reports). Other public health organizations may also use this evaluation to inform aspects of their surveillance report development and evaluation. The evaluation results have provided PHO with direction on how to improve its provincial infectious disease surveillance reporting moving forward, and formed a basis for

    There are myriad pulmonary conditions associated with HIV, ranging from acute infections to chronic noncommunicable diseases. The epidemiology of these diseases has changed significantly in the era of widespread antiretroviral therapy. Evaluation of the HIV-infected patient involves assessment of the severity of illness and a thorough yet efficient pursuit of definitive diagnosis, which may involve multiple etiologies simultaneously. Important clues to a diagnosis include medical and social history, demographic details such as travel and geography of residence, substance use, sexual practices, and domiciliary and incarceration status. CD4 cell count is a tremendously useful measure of immune function and risk for HIV-related diseases, and helps narrow down the differential. Careful history of current symptoms and physical examination with particular attention to extrapulmonary signs are crucial early steps. Many adjunctive laboratory studies can suggest or rule out particular diagnoses. Pulmonary function testing (PFT) may aid in characterization of several chronic noninfectious illnesses accelerated by HIV. Chest radiograph and computed tomography (CT) scan allow for classification of diseases by pathognomonic imaging patterns, although many infectious conditions present atypically, particularly with lower CD4 counts. Ultimately, definitive diagnosis with sputum, bronchoscopy with bronchoalveolar lavage, or lung tissue is often needed. It is of utmost importance to maintain a high degree of suspicion for HIV in otherwise undiagnosed patients, as the first presentation of HIV may be via an acute pulmonary illness.

    To evaluate the nutritional status of children with persistent cholestasis and to compare the anthropometric indices between children with and without liver cirrhosis and children with and without jaundice. Children with persistent cholestasis, i.e. increased direct bilirrubin or changes in the canalicular enzyme gamma-glutamyl transferase (GGT), were included. The anthropometric measures were weight (W), height or length (H), arm circumference (AC), triceps skinfold thickness (TST), arm muscle circumference (AMC), and body mass index (BMI). Ninety-one children with cholestasis, with current median age of 12 months, were evaluated. W/age (A) and H/A indices below -2 Z-scores were observed in 33% and 30.8% of patients, respectively. Concerning the W/H index and BMI, only 12% and 16% of patients, respectively, were below -2 Z-scores. Regarding AC, 43.8% of 89 evaluated patients had some depletion. Observing the TST, 64% of patients had depletion, and 71.1% of the 45 evaluated patients had some degree of depletion regarding the ACM index. Evaluation using weight in patients with chronic liver diseases may overestimate the nutritional status due to visceromegaly, subclinical edema, or ascites. Indices that correlate weight and height, such as W/H and BMI, may also not show depletion because of the chronic condition in which there are depletion of both weight and height. TST, AC, and ACM are parameters that better estimate nutritional status and should be part of the management of patients with liver diseases and cholestasis.

    Rheumatic diseases have repercussions in hand function. The m-SACRAH (modified Score for the Assessment and quantification of Chronic Rheumatoid Affections of the Hands) questionnaire evaluates hand function according to the patient's opinion. Our aim was to look for the clinical and para-clinical variables that correlate with m-SACRAH in rheumatic diseases. Consecutive patients with diagnoses of rheumatoid arthritis (RA), osteoarthritis (OA), gout, and systemic sclerosis (SS) with hand involvement and who agreed to participate, answered the m-SACRAH and Health Assessment Questionnaire Disability Index (HAQ-DI) and underwent blinded and independent rheumatologist and physiatrist evaluations. Nerve conduction studies (NCS) and hand ultrasonography (USG) were performed. Spearman's correlation and the Mann-Whitney U-test. Forty patients were included. There were 72% women and mean age of 49.25 ± 14.2 years. According to m-SACRAH patients were dived into two groups (mild vs. moderate-severe), only the number limited to motion joints were different among them (median 2 vs. 8 P = 0.036). Patients' perspective variables had a good correlation (HAQ-DI/mSACRAH: r = 0.43, P hand function with physiatrist evaluations: passive range of motion (r = -0.49, P = 0.001), sum of affected pinches (r = 0.66, P = 0.001), limited to motion joints (r = 0.34, P < 0.05) and palm-finger distance (r = 0.50, P = 0.05). Regarding para-clinical evaluations, only tenosynovitis by ultrasonography correlated with HAQ-Di (r = 0.357, P < 0.05). Patients' perspectives correlated with the number of limited motion joints but with none of the other physicians' and para-clinical evaluations. The patients' opinion about their function should play a major role in their management. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

    It is well known that Parkinson's disease is characterized by a variety of non-motor symptoms. A gustatory deficit is hypothesized to be one of them although few and only cross-sectional studies are available. The aim of our pilot study was to prospectively investigate the taste function in Parkinson's disease patients after some years from the first evaluation (mean follow-up 4.35 ± 0.49 years; time range 3.5-5.6 years). A group of 26 patients was re-examined (16 males and 10 females; mean age 70.9 ± 8.4 years, range 54-88 years). Taste function was assessed in one session, by means of the Whole Mouth Test (WMT) and Taste Strips Test (TST). Olfaction was also evaluated with the Sniffin' Sticks Identification Test (SST). All these tests are commercially available (Burghart Company, Germany). All patients were able to understand and complete the procedure. Although scores decreased over time, no significant difference was found between global taste scores of first and second evaluation, neither comparing every single taste quality (WMT: p = 0.234, Mann-Whitney U test; TST: p = 0.747, Mann-Whitney U test; McNemar chi-square in the range of 0-1.455). These results confirm a persistent but slight and stable taste impairment, in patients with Parkinson's disease. Future studies on a much larger sample of patients are certainly required.

    Histologic assessment of mucosal disease activity has been increasingly used in clinical trials of treatment for Crohn's disease. However, the operating properties of the currently existing histologic scoring indices remain unclear. A systematic review was undertaken to evaluate the development and operating characteristics of available histologic disease activity indices in Crohn's disease. Electronic searches of MEDLINE, EMBASE, PubMed, and the Cochrane Library (CENTRAL) databases from inception to 20 July 2016 were supplemented by manual reviews of bibliographies and abstracts submitted to major gastroenterology meetings (Digestive Disease Week, United European Gastroenterology Week, European Crohn's and Colitis Organisation). Any study design (e.g. randomised controlled trial, cohort study, case series) that evaluated a histologic disease activity index in patients with Crohn's disease was considered for inclusion. Study participants included adult patients (> 16 years), diagnosed with Crohn's disease using conventional clinical, radiographic or endoscopic criteria. Two authors independently reviewed the titles and abstracts of the studies identified from the literature search. The full text of potentially relevant citations were reviewed for inclusion and the study investigators were contacted as needed for clarification. Any disagreements regarding study eligibility were resolved by discussion and consensus with a third author.Two authors independently extracted and recorded data using a standard form. The following data were recorded from each eligible study: number of patients enrolled; number of patients per treatment arm; patient characteristics: age and gender distribution; description of histologic disease activity index utilized; and outcomes such as content validity, construct validity, criterion validity, responsiveness, intra-rater reliability, inter-rater reliability, and feasibility.

    Full Text Available Nonalcoholic fatty liver disease (NAFLD is the most common cause of elevated liver function tests results, after the commonly investigated causes have been excluded, and frequently coexists with type 2 diabetes mellitus (T2DM because the conditions have common risk factors. As both T2DM and NAFLD are related to adverse outcomes of the other, diagnosis and valuation of fatty liver is an important part of the management of diabetes. Although noninvasive methods, such as biomarkers, panel markers, and imaging, may support a diagnostic evaluation of NAFLD patients, accurate histopathological findings cannot be achieved without a liver biopsy. As it is important to know whether steatohepatitis and liver fibrosis are present for the management of NAFLD, liver biopsy remains the gold standard for NAFLD diagnosis and evaluation. Therefore, new investigations of the pathogenesis of NAFLD are necessary to develop useful biomarkers that could provide a reliable noninvasive alternative to liver biopsy.

    This paper introduces the concept of instrumental variables (IVs) as a means of providing an unbiased estimate of treatment effects in evaluating disease management (DM) programme effectiveness. Model development is described using zip codes as the IV. Three diabetes DM outcomes were evaluated: annual diabetes costs, emergency department (ED) visits and hospital days. Both ordinary least squares (OLS) and IV estimates showed a significant treatment effect for diabetes costs (P = 0.011) but neither model produced a significant treatment effect for ED visits. However, the IV estimate showed a significant treatment effect for hospital days (P = 0.006) whereas the OLS model did not. These results illustrate the utility of IV estimation when the OLS model is sensitive to the confounding effect of hidden bias.

    To share outcomes and lessons learned from an evaluation of disease management (DM) programs for asthma, congestive heart failure (CHF), and diabetes for TRICARE patients. Multiyear evaluation of participants in voluntary, opt-out DM programs. Patient-centered programs, administered by 3 regional contractors, provide phone-based consultations with a care manager, educational materials, and newsletters. The study sample consisted of 23,793 asthma, 4092 CHF, and 29,604 diabetes patients with at least 6 months' tenure in the program. Medical claims were analyzed to quantify program effect on healthcare utilization, medical costs, and clinical outcomes. Multivariate regression analysis with an historical control group was used to predict patient outcomes in the absence of DM. The difference between actual and predicted DM patient outcomes was attributed to the program. A patient survey collected data on program satisfaction and perceived usefulness of program information and services. Modest improvements in patient outcomes included reduced inpatient days and medical costs, and (with few exceptions) increased percentages of patients receiving appropriate medications and tests. Annual per patient reductions in medical costs were $453, $371, and $783 for asthma, CHF, and diabetes program participants, respectively. The estimated return on investment was $1.26 per $1.00 spent on DM services. Findings suggest that the DM programs more than pay for themselves, in addition to improving patient health and quality of life. Lessons learned in program design, implementation, effectiveness, and evaluation may benefit employers contemplating DM, DM providers, and evaluators of DM programs.

    Gastroesophageal reflux disease (GERD) contributes to substantial medication use and costs worldwide. Economic evaluations provide insight into the value of healthcare, taking into account cost, quality, and benefits of particular treatments. Our objectives were to systematically review the existing literature to identify economic evaluations of GERD management strategies, to assess the scientific quality of these reports, and to summarize the economic outcomes of these evaluations. We identified economic evaluations and cost studies of GERD management strategies by searching PubMed and the UK NHS Economic Evaluation Database via the Cochrane Library. Searching was restricted to articles in English-language journals from July 2003 to July 2013. Cost-identification articles were excluded from the final analysis. Eighteen articles were included in the final analysis; 61 % of these met all criteria for quality reporting. Overall, proton pump inhibitor (PPI) therapy was preferred (most effective and least costly) as empiric therapy for patients with reflux symptoms, except in patient populations with high Helicobacter pylori prevalence (>40 %). Initial empiric PPI therapy (vs. initial endoscopy stratification or H. pylori testing) is likely the most cost-effective initial strategy for patients with typical GERD symptoms. Surgery may be cost effective in patients with chronic GERD symptoms at time horizons of 3-10 years. Endoscopic anti-reflux procedures were not cost effective based on available data. Further economic evaluations should adhere to standard reporting measures of cost estimates and outcomes, and should attempt to account for and compare the large heterogeneity of patient phenotypes and treatment effects seen with anti-reflux therapies.

    With antimicrobial resistance increasing worldwide, there is a great need to use automated antimicrobial decision support systems (ADSSs) to lower antimicrobial resistance rates by promoting appropriate antimicrobial use. However, they are infrequently used mostly because of their poor interoperability with different health information technologies. Ontologies can augment portable ADSSs by providing an explicit knowledge representation for biomedical entities and their relationships, helping to standardize and integrate heterogeneous data resources. We developed a bacterial clinical infectious diseases ontology (BCIDO) using Protégé-OWL. BCIDO defines a controlled terminology for clinical infectious diseases along with domain knowledge commonly used in hospital settings for clinical infectious disease treatment decision-making. BCIDO has 599 classes and 2355 object properties. Terms were imported from or mapped to Systematized Nomenclature of Medicine, Unified Medical Language System, RxNorm and National Center for Bitechnology Information Organismal Classification where possible. Domain expert evaluation using the “laddering” technique, ontology visualization, and clinical notes and scenarios, confirmed the correctness and potential usefulness of BCIDO. PMID:24551353

    Advanced pulmonary disorders are linked to esophageal hypomotility and reflux disease. However, characterization of esophageal function using high resolution manometry (HRM) and ambulatory pH monitoring, segregation by pulmonary pathology, and comparison to traditional reflux disease are all limited in the literature. Over a 4 year period, 73 patients (55.2 ± 1.3 years, 44F) were identified who underwent esophageal function testing as part of lung transplant evaluation for advanced pulmonary disease (interstitial lung disease, ILD = 47, obstructive lung disease, OLD = 24, other = 2). Proportions of patients with motor dysfunction (≥ 80% failed sequences = severe hypomotility) and/or abnormal reflux parameters (acid exposure time, AET ≥ 4%) were determined, and compared to a cohort of 1081 patients (48.4 ± 0.4 years, 613F) referred for esophageal function testing prior to antireflux surgery (ARS). The proportion of esophageal body hypomotility was significantly higher within advanced pulmonary disease categories (35.6%), particularly ILD (44.7%), compared to ARS patients (12.1%, P < 0.0001). Abnormal AET was noted in 56.5%, and was similar between ILD and OLD, but less frequent than in the ARS group (P = 0.04). Post-transplant chronic rejection trended towards association with pretransplant elevated AET in OLD (P = 0.08) but not ILD. Mortality was not predicted by esophageal motor pattern or reflux evidence. Interstitial lung disease has a highly significant association with esophageal body hypomotility. Consequently, prevalence of abnormal esophageal acid exposure is high, but implications for post lung transplant chronic rejection remain unclear. © 2013 John Wiley & Sons Ltd.

    Most of cerebrovascular disease are composed of vascular occulusive changes and hemorrhage. Now a day, the computed tomography is the best way for evaluation of cerebrovascular disease including detection of nature, location, and associated changes. This study includes evaluation of computed tomography of 70 patients with cerebrovascular disease during the period of 10 months from April. 1983 to Feb. 1984 in Department of Radiology, Ewha Womans University Hospital. The results were as follows: 1. Age distribution of the total 70 patients was broad ranging from 25 years to 79 years. 78.6% of patients were over the age of 50. The male and female sex ratio was 1.4:1. 2. 4 out of 70 patients were normal and 66 patients revealed abnormal on C.T. findings; those were intracranial hemorrhage (28 patients), cerebral infarction (34 patients) and brain atrophy (4 patients). 3. In cases of cerebral infarction, the cerebral hemisphere was most common site of lesion (28 cases), and next was basal ganglia (2 cases). Most of the infarcts in cerebral hemisphere were located in the parietal and temporal lobes. 4. In cases of intracranial hemorrhage, the basal ganglia was most common site of lesion (15 cases). The next common site was cerebral hemisphere (9 cases). 6 patients of all intracranial hemorrhage were combined with intraventricular hemorrhage. Ratio of right and left was 2:3. 5. In patients with motor weakness or hemiparesis, more common findings on CT scan were cerebral infarction. In case with hemiplegia, more common CT findings were intracerebral hemorrhage. 6. Of the 40 cases thought to be cerebral infarction initially by clinical findings and spinal tap. 8 cases (20.0%) were proved to be cerebral hemorrhage by the CT scan. However, of the 22 cases thought to be cerebral hemorrhage, initially, only two cases (9.0%) were cerebral infarction.

    We describe the first case of severe hypernatremia associated to laparoscopic surgery for hydatid cyst in an adult patient after the use of hypertonic saline solution with complete resolution. Severe hypernatremia is an unusual fact at the immediate postoperative period but may have fatal consequences for the patient and need immediate action. The patient reached a serum sodium concentration of 179 mmol/L without adverse effects after 6 days of treatment. Laparoscopy could play a crucial role in Na+ absorption due to high intraabdominal pressure caused by the pneumoperitoneum and its limitations to avoid peritoneal absorption of hypertonic saline solution. The relation between this surgical technique and the severe complication is discussed. More experience is needed in terms of safety for the patient. Copyright © 2016 Elsevier Inc.

    2016-01-01

    Improved surgical and medical therapy have prolonged survival in patients with congenital heart disease (CHD) such that general medical conditions like coronary artery disease (CAD) are now the main determinants of mortality. A summary of the association of CAD with CHD, as well as a discussion of the radiologic evaluation of the coronary arteries in adults with CHD is described herein. Cross sectional imaging to evaluate CAD in adults with CHD should follow the same appropriateness criteria as gender and aged matched patients without CHD. Coronary CT imaging may be particularly valuable in evaluating the coronary arteries in this patient population as invasive coronary angiography may prove challenging secondary to complicated or unconventional anatomy of the coronary arteries. Further, typical methods for evaluating CAD such as stress or echocardiography may be impractical in adults with CHD. Finally, delineating the anatomic relationship of the coronary arteries and their relationship with the sternum, chest wall, conduits, grafts, and valves is highly recommended in patients with CHD prior to reintervention to avoid iatrogenic complications.

    Purpose To evaluate the subjective and objective measures of ocular surface disease in patients with glaucoma. Design Cross-sectional study. Participants Sixty-four glaucoma subjects with bilateral visual field (VF) loss and 59 glaucoma suspects with normal VFs. Methods Consecutive patients were recruited prospectively from the Wilmer Eye Institute Glaucoma Clinic. Main Outcome Measures Tear film breakup time (TBUT), corneal staining score (0–15), and Schirmer’s test results were included as objective metrics, whereas the Ocular Surface Disease Index (OSDI) questionnaire was administered to assess symptoms. Total OSDI score, vision-related subscore (derived from questions about vision and task performance), and discomfort-related subscore (derived from questions about ocular surface discomfort) were calculated for each subject. Results Seventy-five percent (48/64) of glaucoma subjects and 41% (24/59) of glaucoma suspects were receiving topical medications. The corneal staining grade was greater in glaucoma subjects than in glaucoma suspects (6.4 vs. 4.1; P0.20 for both). Multivariate regression models showed that topical glaucoma therapy burden was associated with a significantly higher total corneal staining grade (β, +0.9 for each additional glaucoma drop; 95% confidence interval [CI], 0.5–1.3; P0.20 for both). Glaucoma subjects had significantly higher total OSDI scores than glaucoma suspects (16.7 vs. 7.9; Pglaucoma group (11.1 vs. 3.3; Pglaucoma therapy burden was not associated with higher total OSDI score or vision- or discomfort-related subscore (P>0.20 for all). Conclusions Glaucoma is associated with significant ocular surface disease, and topical glaucoma therapy burden seems predictive of corneal staining severity. However, OSDI is a poor metric for capturing ocular surface disease in glaucoma because symptoms seem to be related largely to VF loss. PMID:23714318

    Full Text Available Chronic kidney disease (CKD is a growing problem worldwide. Clinical and epidemiologic studies have shown that structural and functional changes that occur in major arteries are a major contributing factor to the high mortality in uremic patients. Recent studies have shown a stepwise increase of the carotid-femoral pulse wave velocity (cfPWV from CKD Stage 1 to Stage 5. We evaluated the cfPWV and augmentation index (AIx, as indirect markers of arterial stiffness in patients with nondiabetic CKD and compared the values with normal population; we also evaluated the relationship between various stages of CKD and arterial stiffness markers. This cross-sectional study was carried out in the Department of Nephrology for a duration of two years from January 15, 2012, to January 14, 2014. Fifty patients with nondiabetic CKD were studied along with 50 healthy volunteers who did not have CKD, who served as controls. Assessment of arterial stiffness (blood pressure, PWV, heart rate, aortic augmentation pressure, and AIx was performed using the PeriScope device. PWV positively correlated with systolic and diastolic blood pressure, mean aortic arterial pressure, serum creatinine, and serum uric acid and negatively correlated with estimated glomerular filtration rate. Arterial stiffness increased as CKD stage increased and was higher in nondiabetic CKD group than in the general population. Arterial stiffness progressed gradually from CKD Stage 2 to 5, and then abruptly, in dialysis patients. Measures to decrease the arterial stiffness and its influence on decreasing cardiovascular events need further evaluation.

    Full Text Available Aim. While there are many well-defined serological markers for inflammatory bowel disease (IBD, there is limited evidence that they positively affect clinical outcomes. This study aimed to evaluate the correlation between hepcidin serum levels and disease activity in IBD. Materials and Methods. Eighty-five consecutive IBD patients were enrolled in the study. Hepcidin serum levels were assessed using an enzyme-linked immunosorbent assay (ELISA and were compared with disease activity as well as the interleukin-6 (IL-6 and C-reactive protein (CRP levels. Results. The mean hepcidin serum levels in Crohn’s disease (CD patients in remission and in the active phase were 3837±1436 and 3752±1274 pg/mL, respectively P=0.613. The mean hepcidin serum levels in ulcerative colitis (UC patients in remission and in the active phase were 4285±8623 and 3727±1176 pg/mL, respectively P=0.241. Correlation analysis between inflammatory markers and hepcidin serum levels indicated that there was no correlation between hepcidin levels and IL-6 P=0.582 or CRP P=0.783. Conclusion. As an acute-phase protein, hepcidin seems to have a lower efficacy than other parameters in the detection of activation in IBD.

    Full Text Available Patients with chronic kidney disease (CKD exhibit an increased cancer risk compared to a healthy control population. To be able to estimate the cancer risk of the patients and to assess the impact of interventional therapies thereon, it is of particular interest to measure the patients’ burden of genomic damage. Chromosomal abnormalities, reduced DNA repair, and DNA lesions were found indeed in cells of patients with CKD. Biomarkers for DNA damage measurable in easily accessible cells like peripheral blood lymphocytes are chromosomal aberrations, structural DNA lesions, and oxidatively modified DNA bases. In this review the most common methods quantifying the three parameters mentioned above, the cytokinesis-block micronucleus assay, the comet assay, and the quantification of 8-oxo-7,8-dihydro-2′-deoxyguanosine, are evaluated concerning the feasibility of the analysis and regarding the marker’s potential to predict clinical outcomes.

    If we are to find treatments to postpone, reduce the risk of, or completely prevent the clinical onset of Alzheimer disease (AD), we need faster methods to evaluate promising preclinical AD treatments, new ways to work together in support of common goals, and a determination to expedite the initiation and performance of preclinical AD trials. In this article, we note some of the current challenges, opportunities and emerging strategies in preclinical AD treatment. We describe the Collaboration for Alzheimer’s Prevention (CAP)—a convening, harmonizing and consensus-building initiative to help stakeholders advance AD prevention research with rigour, care and maximal impact—and we demonstrate the impact of CAP on the goals and design of new preclinical AD trials.

    Left ventriculography with RAO projection gives many information about the states of mitral apparatus and of left ventricular function. The knowledge about these are very important to determination of performance, time and method of cardiac surgery in mitral valvular heart diseases. 20 patients of mitral valvular heart disease were studied with left ventriculographies in RAO projection which were taken before open heart surgery at department of radiology, National Medical Center during 1976 to June 1980, Comparing with operative findings and pathologic specimens. The results are as follows; 1. Poor motilities and irregularities of mitral valves which were visible above the fulcrum, and irregularities and severe retraction of the fornix during left ventricular systolic phases on left ventriculographies were compatible to the stage III by Sellers' classification of mitral valvular stenosis on operative findings. Mild degree of irregularities and restriction with smooth fornix suggested the stage I. The findings between these two, the stage II. 2. MI group showed left ventricular dilation without hypertrophy, MS group, no significant effect on LV, Ao group, enlargement with hypertrophy. 3. In Ms and MI groups, ejection fraction were relatively well preserved until grade I-II of NYHA Classification. But grade III-IV revealed decreased ejection fraction. E. F. was below 0.55 in 86% of grade III-IV. In Ao group, grade IV showed well preservation of E. F. 4. The pattern of left ventricular contraction demonstrated hypokinetic synesis or asynesis in 44.4% of grade IV, but was normal in all cases below grade III. Hyperkinetic synesis was visible in all Ao group. 5. Left ventriculography is essential to evaluation of mitral valve apparatus and LV function in mitral heart diseases before cardiac surgery.

    Full Text Available Doppler ultrasound is a non-invasive method for evaluating vascularization and is widely used in clinical practice. Gestational trophoblastic neoplasia includes a group of highly vascularized malignancies derived from placental cells. This review summarizes data found in the literature regarding the applications of Doppler ultrasound in managing patients with gestational trophoblastic neoplasia. The PubMed/Medline, Web of Science, Cochrane and LILACS databases were searched for articles published in English until 2014 using the following keywords: “Gestational trophoblastic disease AND Ultrasonography, Doppler.” Twenty-eight articles met the inclusion criteria and were separated into the 4 following groups according to the aim of the study. (1 Doppler ultrasound does not seem to be capable of differentiating partial from complete moles, but it might be useful when evaluating pregnancies in which a complete mole coexists with a normal fetus. (2 There is controversy in the role of uterine artery Doppler velocimetry in the prediction of development of gestational trophoblastic neoplasia. (3 Doppler ultrasound is a useful tool in the diagnosis of gestational trophoblastic neoplasia because abnormal myometrial vascularization and lower uterine artery Doppler indices seem to be correlated with invasive disease. (4 Lower uterine artery Doppler indices in the diagnosis of gestational trophoblastic neoplasia are associated with methotrexate resistance and might play a role in prognosis. CONCLUSION: Several studies support the importance of Doppler ultrasound in the management of patients with gestational trophoblastic neoplasia, particularly the role of Doppler velocimetry in the prediction of trophoblastic neoplasia and the chemoresistance of trophoblastic tumors. Doppler findings should be used as ancillary tools, along with human chorionic gonadotropin assessment, in the diagnosis of gestational trophoblastic neoplasia.

    Full Text Available Emilie Vallières, Joseph Stuart ElbornCystic Fibrosis and Airways Microbiology Research Group, Queens University Belfast, Belfast, UKAbstract: The cystic fibrosis transmembrane regulator (CFTR gene encodes an ion channel transporter, the CFTR protein. Since its identification in 1989, more than 1,900 sequence variants have been reported, resulting in a wide spectrum of clinical phenotypes. Cystic fibrosis (CF is associated with many CFTR mutants and there is a continuum of disease severity observed. Recent advances in fundamental research have increased our understanding of the consequent molecular defect arising from CF mutations. This knowledge has resulted in the development of CF-specific therapies, targeting either the genetic or the molecular defect. CF care, previously focused on symptom control, is therefore moving toward a "stratified" or "precision" therapeutic approach. This review outlines normal CFTR physiology, the proposed pathologic mechanism underlying CF associated-lung injury, classification of CF mutations, and the CF-specific therapies recently approved or in clinical trials.Keywords: cystic fibrosis, gene mutations, disease severity, evaluation, assessment

    Currently, the most widely used method in the disease management industry for evaluating program effectiveness is the "total population approach." This model is a pretest-posttest design, with the most basic limitation being that without a control group, there may be sources of bias and/or competing extraneous confounding factors that offer plausible rationale explaining the change from baseline. Survival analysis allows for the inclusion of data from censored cases, those subjects who either "survived" the program without experiencing the event (e.g., achievement of target clinical levels, hospitalization) or left the program prematurely, due to disenrollement from the health plan or program, or were lost to follow-up. Additionally, independent variables may be included in the model to help explain the variability in the outcome measure. In order to maximize the potential of this statistical method, validity of the model and research design must be assured. This paper reviews survival analysis as an alternative, and more appropriate, approach to evaluating DM program effectiveness than the current total population approach.

Statistical tests used were Wilcoxon or Student's t-test; PNCB group (N=20) versus the control group (N=20), significant differences were found in body mass index and in several functional variables (spirometric, VC, 6MWT) with worse results observed in the NCB group. In the comparison between the COPD group (N=20) versus the NCB group, although patients with COPD had worse spirometric and 6MWT values, the capnographic variables mean phase 2 slope (Slp2), mean phase 3 slope normalized by the mean expiratory volume, or mean phase 3 slope normalized by the end-tidal CO2 concentration were similar. These findings may indicate that the gas elimination curves are not sensitive enough to monitor the severity of structural abnormalities. The role of normalized phase 3 slope may be worth exploring as a more sensitive index of small airway disease

    Significant advances in the management of children with congenital heart disease (CHD) have resulted in marked improvements in survival and life expectancy. Thus, there is an increased emphasis on promoting physical activity to optimise healthy development and long-term cardiovascular health. Evaluation of physical activity levels as part of ongoing clinical care is recommended to facilitate physical activity counselling and/or exercise prescription. Physical activity is a complex health behaviour that is challenging to evaluate. We provide an overview of techniques for measuring physical activity in children with CHD with a focus on how to do this in the clinical context. Accelerometers are devices that objectively assess intensity and duration of physical activity under free living conditions. They enable evaluation against physical activity guidelines, but are costly and require advanced technical expertise. Pedometers are a simple-to-use and cost-effective alternative, but an outcome metric of daily step count limits classification against guidelines. Commercial wearable activity trackers offer an appealing user experience and can provide valid estimates in children. Furthermore, activity trackers enable remote monitoring of physical activity levels, which may facilitate exercise prescription and activity counselling. Questionnaires are the most cost-effective and time-effective method, but recall error in younger children is a consideration. Routine exercise testing in children with CHD provides important insight into functional status but should not be viewed as a proxy measure of habitual physical activity. Understanding the spectrum and role of physical activity measurement tools is important for clinicians focused on optimising cardiovascular health in children with CHD. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Celiac disease (CD) is a lifelong gluten-sensitive intestinal enteropathy that is multifactorial in its etiology. In the present study, we evaluated basic anthropometric, clinical, laboratory, and histological features of 140 Turkish children with CD. We particularly underscored the association of CD with other autoimmune diseases. During the period from 1999 to 2005, CD was diagnosed in 140 children according to ESPGAN criteria. The age, gender, clinical findings, hematological, and biochemical parameters at diagnosis were noted. Symptoms and signs were recorded. Endoscopic intestinal biopsies were taken from all children. Of the 140 children with CD, 75 (53.6%) were female, and 65 (46.4%) were male. Mean age was 8.56 ± 4.43 years (range 13 months to 18 years). The most frequent symptom was failure to thrive (81.4%), followed by chronic diarrhea (60%). Of the children with CD, nine (6.4%) had type 1 diabetes mellitus (DM), six (4.3%) had familial Mediterranean fever, three (2.1%) had alopecia areata, three (2.1%) had vitiligo, three (2.1%) had Down syndrome, two (1.4%) had lung tuberculosis, two (1.4 %) had autoimmune hepatitis, two (1.4%) had growth hormone deficiency, one (0.7%) had osteogenesis imperfecta, and one (0.7%) had Floating Harbor Syndrome. Elevated serum levels of ALT, CK and AST were detected in 48(34.8%), 50 (38.2%) and 67 (48.6%) children, respectively. The spectrum of clinical findings is very wide. In order to avoid overlooking CD in patients with extra intestinal symptoms and signs, physicians, especially pediatricians, should be informed about new atypical manifestations of CD.

    In the wake of the recent outbreak of Ebola virus disease (EVD) in several African countries, the World Health Organization prioritized the evaluation of treatment with convalescent plasma derived from patients who have recovered from the disease. We evaluated the safety and efficacy of convalescent plasma for the treatment of EVD in Guinea. In this nonrandomized, comparative study, 99 patients of various ages (including pregnant women) with confirmed EVD received two consecutive transfusions of 200 to 250 ml of ABO-compatible convalescent plasma, with each unit of plasma obtained from a separate convalescent donor. The transfusions were initiated on the day of diagnosis or up to 2 days later. The level of neutralizing antibodies against Ebola virus in the plasma was unknown at the time of administration. The control group was 418 patients who had been treated at the same center during the previous 5 months. The primary outcome was the risk of death during the period from 3 to 16 days after diagnosis with adjustments for age and the baseline cycle-threshold value on polymerase-chain-reaction assay; patients who had died before day 3 were excluded. The clinically important difference was defined as an absolute reduction in mortality of 20 percentage points in the convalescent-plasma group as compared with the control group. A total of 84 patients who were treated with plasma were included in the primary analysis. At baseline, the convalescent-plasma group had slightly higher cycle-threshold values and a shorter duration of symptoms than did the control group, along with a higher frequency of eye redness and difficulty in swallowing. From day 3 to day 16 after diagnosis, the risk of death was 31% in the convalescent-plasma group and 38% in the control group (risk difference, -7 percentage points; 95% confidence interval [CI], -18 to 4). The difference was reduced after adjustment for age and cycle-threshold value (adjusted risk difference, -3 percentage points; 95

    Progressive changes in the substantia nigra pars compacta and locus ceruleus of patients with Parkinson disease and Alzheimer disease visualized by neuromelanin MRI and cardiac postganglionic sympathetic nerve function on (123)I-metaiodobenzylguanidine scintigraphy have not been fully evaluated. We compared the diagnostic value of these modalities among patients with early Parkinson disease, late Parkinson disease, and Alzheimer disease. We compared contrast ratios of signal intensity in medial and lateral regions of the substantia nigra pars compacta and locus ceruleus with those of the tegmentum of the midbrain and the pons, respectively, by use of neuromelanin MRI in patients with early Parkinson disease (n = 13), late Parkinson disease (n = 31), Alzheimer disease (n = 6), and age-matched healthy control subjects (n = 20). We calculated heart-to-mediastinum ratios on (123)I-metaiodobenzylguanidine scintigrams after setting regions of interest on the left cardiac ventricle and upper mediastinum. The signal intensity of the lateral substantia nigra pars compacta on neuromelanin MRI was significantly reduced in early and late Parkinson disease, and that of the medial substantia nigra pars compacta was gradually and stage-dependently reduced in Parkinson disease. The signal intensity of the locus ceruleus was obviously reduced in late Parkinson disease. Signal reduction was not significant in the substantia nigra pars compacta and locus ceruleus of patients with Alzheimer disease. The heart-to-mediastinum ratio on (123)I-metaiodobenzylguanidine scintigrams was stage-dependently reduced in Parkinson disease and normal in Alzheimer disease. The signal intensity ratios in substantia nigra pars compacta and locus ceruleus on neuromelanin MRI positively correlated with the heart-to-mediastinum ratio on (123)I-metaiodobenzylguanidine scintigrams. Both neuromelanin MRI and (123)I-metaiodobenzylguanidine scintigraphy can help to evaluate disease progression in Parkinson

    To evaluate a routine MR enterography (MRE) protocol for patients with Crohn's disease (CD) in order to assess and rank the subjectively most important sequences regarding diagnostic decisions. We prospectively examined 84 patients (42 male) with known CD using a coronal T2 / T1-weighted balanced SSFP (TrueFISP), axial T2-weighted single shot TSE (HASTE) as well as an axial T1-weighted gradient-echo sequence (2D-FLASH) before intravenous contrast application and a 2D-FLASH sequence with axial and coronal orientation after intravenous contrast application. 4 experienced radiologists subjectively evaluated the sequences independently using a scale between 1 and 5 (1 = excellent; 5 = non-diagnostic) regarding their diagnostic significance for a final radiologic decision. The ranking of the different sequences was statistically tested by the Friedman analysis. The following ranking was found: HASTE sequences were ranked prior to contrast-enhanced axial gradient-echo (2D-FLASH). The third to fifth ranking was TrueFISP, the axial contrast-enhanced 2D-FLASH and the 2D-FLASH without contrast, respectively. Differences between the first and second rank were significant (p axial HASTE and coronal TrueFISP were ranked as number 1 and 3. The examination protocol should be completed by a coronal T1-weighted gradient-echo-sequence after contrast injection, which can be supplemented by an axial acquisition. The T1-weighted gradient-echo sequence without contrast could be omitted. © Georg Thieme Verlag KG Stuttgart · New York.

    Background The 2007 update to the American Heart Association (AHA) Guidelines for Cardiovascular Disease Prevention in Women recommend a simplified approach to risk stratification. We assigned Women's Health Initiative (WHI) participants to risk categories as described in the guideline, and evaluated clinical event rates within and between strata. Methods and Results The WHI enrolled 161,808 women aged 50-79 years, and followed them prospectively for 7.8 years (mean). Applying the 2007 AHA guideline categories, 11% of women were high risk, 72% at-risk and 4% optimal risk; 13% of women did not fall into any category, that is, lacked risk factors but did not adhere to a healthy lifestyle (moderate intensity exercise for 30 minute most days and 20% (AUC for Framingham risk 0.724, for AHA risk 0.664; p<0.0001). Conclusions Risk stratification as proposed in the 2007 AHA guideline is simple, accessible to patients and providers, and identifies cardiovascular risk with accuracy similar to that of the current Framingham algorithm.

    To show celiac disease (CD) and its poor pregnancy outcome relationship, and to demonstrate the importance of a gluten-free diet together with low-dose low-molecular-weight heparin (LMWH) and low-dose corticosteroid (LDC) in the management of pregnancies with CD. This study consisted of 2 groups of patients. Six patients with CD (control group) on a gluten-free diet were monitored during their first pregnancies within the framework of antenatal care program and their pregnancy outcomes were compared with eight poorly-treated pregnant patients with CD (study group) who were referred from other medical institutions. LMWH (enoxaparine 1x2000 Anti-XA IU/0.2 mL/day), and LDC (methylprednisolone 1x4 mg p.o/day) were used in the control group. Their obstetric histories and outcomes of their last pregnancies were compared. The patients' obstetric risk levels were evaluated using the "Beksac Obstetrics Index" (BOI). There were miscarriages in 50% of the study group. There were also 50% and 75% preterm deliveries in the control and study groups, respectively. The BOI of the study group was significantly worse than the control group (1.31 vs. 0.31±0.21, pwomen with CD.

    Parkinson's disease is a well known representent of the movement disorder group of neurological disorders. The diagnosis of Parkinson's disease is based on specific symptoms and signs of movement abnormalities. In addition to classic motor symptoms, Parkinson's disease has characteristic non-motor features, and some of these emerges the classic signs. The authors discuss characteristics and therapeutic interventions in Parkinson's disease related sleep disturbances. The authors reviewed and summarised literature data on sleep disorders in Parkinson's disease published in the PubMed database up to January 2015. Sleep problems are important non-motor complains (insomnia, hypersomnia, REM behaviour disorder, sleep apnea and restless legs syndrome). The neurodegenerative process of the brain-stem, the effect of symptoms of Parkinson's disease on sleep and concomitant sleep disorders constitute the background of the patient's complains. Appropriate diagnosis and therapy of the consequential or concomitant sleep disorders in Parkinson's disease will help to improve the patient's quality of life.

    Background. Radiologic assessment of pancreaticobiliary ductal disease (PBDD) in children currently consists of physiologic tests (radionuclide examinations) or invasive anatomic studies (ERCP and PTC). An accurate noninvasive and reproducible examination that can direct the subsequent need for more invasive studies would be helpful in this patient group. Objective. To determine the effectiveness of MRCP as a screening tool for PBBD in the pediatric population. Materials and methods. Over the last year, 33 patients ranging from 7 months to 20 years of age were prospectively evaluated with MRCP on a 1.5 T magnet. One patient was examined twice, several months apart. Thirteen patients had liver transplants. Coronal SPGR and heavily T-2W FSE cross-sectional images were obtained. Standard and oblique 2- to 6-cm-thick slab SSFSE (single-shot fast spin echo) acquisition and 3D MIP reconstruction of 2D FSE images were obtained in the planes of the CBD and pancreatic duct. Nine studies were performed with the patient under sedation with chloral hydrate or nembutal and fentanyl with quiet respiration, and the non-sedated patients were assessed with single breath hold or quiet respiration. Three patients received secretin. MRCP results were correlated with ERCP (9), PTC (7), liver biopsy (13), clinical information (6), surgery (3), and autopsy (2). Results. All 34 studies performed were considered diagnostic. Periportal fluid, proximal bowel fluid, and gallbladder distention did not significantly diminish the diagnostic information in any cases. Motion artifact did not cause serious degradation in image quality. MRCP depicted abnormalities including stones, stricture, intraductal tumor, and extrinsic compression, all of which were confirmed at ERCP, PTC (two unsuccessful in patients with non-dilated ducts by MRCP), surgery, liver biopsy, and autopsy. There were no false-negative examinations. Normal pancreatic studies performed to exclude pancreas divisum were followed

    Huntington's disease is an autosomal dominant neurodegenerative disorder characterized by motor and cognitive impairment. At the early stages of the disease scientists have observed psychological changes and differences in patients' alpha, beta and theta powers. The early diagnosis of Huntington's disease is very important in order to administrate the correct medication to the patients and slow down the progress of the disease. This paper aims to suggest a protocol in which experiments could be based on, in an attempt to make an early diagnosis of the disease by taking into consideration the patients' electroencephalographic recordings during the early stages of the disease, as well as the methods of processing and classifying those EEG signals.

    Twenty patients with known metastatic cancer or high-risk primary cancer developed new lesions on Tc/sup 99m/ bone scans and had normal plain radiographs. Spinal computed tomography (CT) was performed on all new bone-scan-positive lesions in minimal examination time. Fifteen patients had extensive metastatic vertebral disease and received local radiotherapy. One patient with new metastatic vertebral disease on CT was treated only with chemotherapy and developed acute spinal cord compression. Four patients had discogenic disease or degenerative disease but no evidence of metastases. Radionuclide bone scans are more sensitive but less specific than plain radiographs in detecting early bone metastases. Early and accurate diagnosis of metastasis is particularly important in the axial spine to prevent epidural compression and fracture. Spinal CT is valuable for identifying the presence and extent of vertebral metastases, as well as the presence of benign disease in cancer patients.

    AIM To delay surgery until the patient is in a better condition, and thus to decrease postoperative morbidity. METHODS Using this algorithm we treated three patients aged 55, 75 and 80 years. In all three patients the clinical presentation was fever without a clear source of infection; all had nonspecific symptoms such as general malaise, dyspnea, and abdominal discomfort in the previous 15 d. They came to the emergency room at our hospital due to deterioration of their general condition. Analytical tests showed leukocytosis, neutrophilia and increased polymerase chain reaction. In all cases an abdominal computed tomography (CT) was performed and liver hydatid abscess (LHA) was detected. The mean size of the LHA was 12 cm. RESULTS All patients underwent CT-guided percutaneous drainage. The purulent material obtained was cultured, and Klebsiella pneumoniae, Streptococcus viridans and Streptococcus salivarius were identified. Antibiotic treatment was given adapted to antibiotic sensitivity testing. Surgery was performed two weeks after admission, once the patient’s condition had improved. All three patients underwent an almost total cystectomy, cholecystectomy and omentoplasty in the residual cavity. Complications were: Clavien I (atelectasis and pleural effusion) and Clavien II (transfusion). The average length of stay (pre and postoperative) was 23 d. At the follow-up, no relapses were recorded. CONCLUSION LHA management is not standardized. Emergency surgery offers suboptimal results. Percutaneous drainage plus antibiotics allows improving patient’s general condition. This enables treating patients in greater safety and also reduces complications. PMID:28144393

    2006-05-01

    Full Text Available Abstract Background Addison's disease, also known as hypoadrenocorticism, has been reported in many individual dogs, although some breeds exhibit a greater incidence than the population as a whole. Addison's is presumed to be an autoimmune mediated hereditary defect but the mode of inheritance remains unclear. In particular, the heritability and mode of inheritance have not been defined for the Portuguese Water Dog although Addison's is known to be prevalent in the breed. Results The analyses present clear evidence that establishes Addison's disease as an inherited disorder in the Portuguese Water Dog with an estimate of heritability of 0.49 (± 0.16; there were no differences in risk for disease across sexes (p > 0.49. Further, the complex segregation analysis provides suggestive evidence that Addison's disease in the Portuguese Water Dog is inherited under the control of a single, autosomal recessive locus. Conclusion The high heritability and mode of inheritance of Addison's disease in the Portuguese Water Dog should enable the detection of segregating markers in a genome-wide scan and the identification of a locus linked to Addison's. Though the confirmation of Addison's disease as an autosomal recessive disorder must wait until the gene is identified, breeders of these dogs may wish to keep the present findings in mind as they plan their breeding programs to select against producing affected dogs.

    Study of the exhaustibility and reliability of the recording of obligatory notifiable diseases (EDO) and the accumulated incidence of the EDO in a health area. Descriptive study. Community setting. Epidemiological surveillance. People who have suffered in 1996 some EDO (excluded measles, rubella, mumps, chickenpox and influenza). They have been selected a total of 205 EDO-disease cases starting from the two recording systems: laboratory and obligatory surveillance diseases system. The exhaustibility of the laboratory has been 82%, 95% confidence interval (76-87%) and that of the EDO system 45%, 95% confidence interval (38-52%). The rate kappa for the diseases global is 0.42 95%, confidence interval (0.4-0.43) and the specific accordance proportion 0.27, 95% confidence interval (0.21-0.34). The cases search in the recording of the laboratory increases the incidence declared to the EDO system in all the diseases. The diseases with greater incidence are the hepatitis (73.59 x 10(5)), the pulmonary tuberculosis (27.07 x 10(5)) and the syphilis (18.05 x 10(5)). The EDO system presents a clear understatement, variable according to the different diseases and being maximum for the hepatitis B and C. The laboratory quantifies a high exhaustibility, and it can increase between 55 and 30% the EDO recording cases, increasing the knowledge of the morbidity caused by EDO in the Area 11. The valuation of the EDO in addition to improving the information for the assumptions of decisions in sanitary planning, optimizes the necessary elements when it is compared the EDO incidence among different geographical areas or within a same area at a different time.

    To retrospectively compare the accuracy of axial and coronal planes of CT enterography for detection of pathologic findings of Crohn disease. 168 patients who were suspected of having Crohn disease underwent CT enterography. 66 patients who were diagnosed Crohn disease were retrospectively evaluated (endoscopic biopsy of terminal ileum: 12 patients, segmental resection of small bowel: 6 patients, diagnosed based on a combination of clinical, histopathological and imaging findings: 48 patients). 2 radiologists reviewed axial planes of CT enterography and one month later reviewed coronal planes. CT enterography findings of active phase, chronic phase and complications of Crohn disease were evaluated and then compared with axial and coronal planes by using chi-square test. Mucosal hyperenhancement, wall thickening, and mesenteric fat stranding were more detected on axial planes, which were CT findings of active Crohn disease. Pseudosacculation, fibrotic strictures, fistulas, abscesses were more detected on coronal planes, which were CT findings of chronic Crohn disease or complications. In particular, pseudosacculation and fibrotic strictures were significantly more detected on coronal planes. When evaluating CT enterography in Crohn disease, coronal planes provide more useful diagnostic information of pseudosacculation and fibrotic strictures.

    Complex aortic disease continues to have a high mortality and morbidity despite advances in medical and surgical treatment. Repair of thoracoabdominal aneurysms, treatment of patients with connective tissue disorders, and the approach to dissections of the ascending and descending aorta have evolved over time; however, the results of intervention in all but highly specialized centers remain poor. As vascular surgeons, our role must extend beyond that of the pure technician; we have been vested with the life-long care of these patients and, therefore, have a responsibility to the patient in addition the scientific community and society at large to create a strategy for management that serves all three interests justly. We will outline some of the changes in the conceptual approach that we consider important to the treatment of complex aortic disease.

    Kidney renal failure means that one's kidney have unexpectedly stopped functioning, i.e., once chronic disease is exposed, the presence or degree of kidney dysfunction and its progression must be assessed, and the underlying syndrome has to be diagnosed. Although the patient's history and physical examination may denote good practice, some key information has to be obtained from valuation of the glomerular filtration rate, and the analysis of serum biomarkers. Indeed, chronic kidney sickness depicts anomalous kidney function and/or its makeup, i.e., there is evidence that treatment may avoid or delay its progression, either by reducing and prevent the development of some associated complications, namely hypertension, obesity, diabetes mellitus, and cardiovascular complications. Acute kidney injury appears abruptly, with a rapid deterioration of the renal function, but is often reversible if it is recognized early and treated promptly. In both situations, i.e., acute kidney injury and chronic kidney disease, an early intervention can significantly improve the prognosis. The assessment of these pathologies is therefore mandatory, although it is hard to do it with traditional methodologies and existing tools for problem solving. Hence, in this work, we will focus on the development of a hybrid decision support system, in terms of its knowledge representation and reasoning procedures based on Logic Programming, that will allow one to consider incomplete, unknown, and even contradictory information, complemented with an approach to computing centered on Artificial Neural Networks, in order to weigh the Degree-of-Confidence that one has on such a happening. The present study involved 558 patients with an age average of 51.7 years and the chronic kidney disease was observed in 175 cases. The dataset comprise twenty four variables, grouped into five main categories. The proposed model showed a good performance in the diagnosis of chronic kidney disease, since the

    Full Text Available GM1 gangliosidosis is a fatal lysosomal disorder, for which there is no effective treatment. Adeno-associated virus (AAV gene therapy in GM1 cats has resulted in a greater than 6-fold increase in lifespan, with many cats remaining alive at >5.7 years of age, with minimal clinical signs. Glycolipids are the principal storage product in GM1 gangliosidosis whose pathogenic mechanism is not completely understood. Targeted lipidomics analysis was performed to better define disease mechanisms and identify markers of disease progression for upcoming clinical trials in humans. 36 sphingolipids and subspecies associated with ganglioside biosynthesis were tested in the cerebrospinal fluid of untreated GM1 cats at a humane endpoint (∼8 months, AAV-treated GM1 cats (∼5 years old, and normal adult controls. In untreated GM1 cats, significant alterations were noted in 16 sphingolipid species, including gangliosides (GM1 and GM3, lactosylceramides, ceramides, sphingomyelins, monohexosylceramides, and sulfatides. Variable degrees of correction in many lipid metabolites reflected the efficacy of AAV gene therapy. Sphingolipid levels were highly predictive of neurologic disease progression, with 11 metabolites having a coefficient of determination (R2 > 0.75. Also, a specific detergent additive significantly increased the recovery of certain lipid species in cerebrospinal fluid samples. This report demonstrates the methodology and utility of targeted lipidomics to examine the pathophysiology of lipid storage disorders.

    Celiac disease (CD) is an autoimmune enteropathy. The disease may be presented with extraintestinal manifestations including neurological findings. Epilepsy and ataxia are well known neurological disorders in CD. But there are very limited numbers of reports on sensory-neural hearing loss in CD in the literature. The aim of this study was to investigate the hearing functions in children with newly diagnosed CD. Ninety-seven (194 ears) [56 girls, 41 boys (age range: 1.5-17 years)] newly diagnosed celiac disease patients and 85 sex and age-matched controls (170 ears) were included in this study. Hearing function was assessed by pure-tone audiometry, speech audiometry, tympanometry and otoacoustic emissions measurements. No significant difference were found between the patients and control groups measurements including the pure-tone audiometry, speech audiometry, tympanometry and otoacoustic emissions No significant difference was found for pure-tone audiometry, speech audiometry, tympanometry and otoacoustic emissions measurements in celiac patients according to the Marsh-Oberhuber classification (P>0.05). Our results showed that hearing functions of children with newly diagnosed CD were similar to healthy controls. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Tiemin Zhang

    Full Text Available Cystic echinococcosis (CE caused by the larval stage of Echinococcus granulosus sensu lato (s.l. is one of the most important zoonotic parasitic diseases worldwide and 10 genotypes (G1-G10 have been reported. In China, almost all the epidemiological and genotyping studies of E. granulosus s.l. are from the west and northwest pasturing areas. However, in Heilongjiang Province of northeastern China, no molecular information is available on E. granulosus s.l. To understand and to speculate on possible transmission patterns of E. granulosus s.l., we molecularly identified and genotyped 10 hydatid cysts from hepatic CE patients in Heilongjiang Province based on mitochondrial cytochrome c oxidase subunit I (cox1, cytochrome b (cytb and NADH dehydrogenase subunit 1 (nad1 genes. Two genotypes were identified, G1 genotype (n = 6 and G7 genotype (n = 4. All the six G1 genotype isolates were identical to each other at the cox1 locus; three and two different sequences were obtained at the cytb and nad1 loci, respectively, with two cytb gene sequences not being described previously. G7 genotype isolates were identical to each other at the cox1, cytb and nad1 loci; however, the cytb gene sequence was not described previously. This is the first report of G7 genotype in humans in China. Three new cytb gene sequences from G1 and G7 genotypes might reflect endemic genetic characterizations. Pigs might be the main intermediate hosts of G7 genotype in our investigated area by homology analysis. The results will aid in making more effective control strategies for the prevention of transmission of E. granulosus s.l.

    Full Text Available Objectives : Rheumatic diseases such as osteoarthritis and rheumatoid arthritis constitute the most frequent pathological states leading to the development of foot deformities, which reduce quality of life and cause disability. The aim of the present study was to compare the results of plantoconturographic examinations, obtained by means of a computer podoscope, in osteoarthritis and rheumatoid arthritis patients. Special attention was paid to the differences in the values of each parameter determining the level of foot function. Material and methods : The study was performed in 94 female patients divided into two groups according to the type of disease. There were 54 patients with rheumatoid arthritis and 40 with osteoarthritis. The control group consisted of 34 healthy women. The plantographic assessment of static foot structure was carried out by means of a device for computer-aided foot examination. Results : A fallen transverse arch of the right foot was statistically much more frequent in the rheumatoid arthritis patients than in osteoarthritis patients or the control group (p < 0.005 and p < 0.05, respectively. Significant differences in the values of the Wejsflog index were observed in the case of left foot between rheumatoid arthritis patients and the control group (p < 0.05. Similarly, there were statistically significant differences in the values of the hallux valgus angle ( for the right foot between rheumatoid arthritis and osteoarthritis patients or control group (in both cases p < 0.05. Conclusions : Rheumatic diseases predispose patients to disturbances of static foot function. The obtained results highlight the importance of diagnosing foot static disturbances in the prevention of destructive changes affecting the functioning of osteoarthritis and rheumatoid arthritis patients.

    Fourteen cases of gestational trophoblastic disease, including five cases before curettage, are reported. Before curettage molar tissue showed a reticular pattern and one case that proceeded to develop into an invasive mole did not show any significant difference from other non-invasive mole. Two cases underwent enhancement of Gd-DTPA, and with this, the implantation site may be diagnosed. After curettage junctional zone was not clear during the period when HCG titer was high. Five cases showed residual molar tissue and MRI was able to depict the tumor and dilatated vesseles. (author).

    Full Text Available Even if Medicine and Computer Science seemapparently intangible domains, they collaborate each otherfor few decades. One of the faces of this cooperation is DataMining, a relative new and multidisciplinary field capable toextract valuable information from large sets of data. Despitethis fact, in cardiology related studies it was rarely used. Weassume that some data mining tools can be used as asubstitute for some complex, expensive, uncomfortable, timeconsuming, and sometimes dangerous medical examinations.This paper aims to show that cardiovascular diseases may bepredicted by classical risk factors analyzed and processed ina “non-invasive” way.

    Living, intact protoscoleces of the British horse and sheep strains of Echinococcus granulosus were subjected to surface radioiodination procedures using /sup 125/I and Iodogen and /sup 125/I-Bolton Hunter reagent. Subsequent combined electron microscopy and autoradiography revealed specific surface membrane labelling with the Iodogen procedure, but significant tegumental labelling with the Bolton-Hunter reagent. The two parasite strains yielded different profiles of electrophoretically separated labelled proteins; the Iodogen method, not surprisingly, resulted in a less complex pattern of labelled polypeptides than the Bolton and Hunter reagent.

  5. Evaluating Periodontal Treatment to Prevent Cardiovascular Disease: Challenges and Possible Solutions.

    Science.gov (United States)

    Merchant, Anwar T; Virani, Salim S

    2017-01-01

    Periodontal disease is correlated with cardiovascular disease (CVD) in observational studies, but a causal connection has not been established. The empirical evidence linking periodontal disease and CVD consists of a large body of observational and mechanistic studies, but a limited number of clinical trials evaluating the effects of periodontal treatment on surrogate CVD endpoints. No randomized controlled trial has been conducted to evaluate the effect of periodontal treatment on CVD risk. In this review, we have summarized these data, described possible biological mechanisms linking periodontal disease and CVD, discussed barriers to conducting a randomized controlled trial to evaluate this hypothesis, and provided an alternative analytical approach using causal inference methods to answer the question. The public health implications of addressing this question can be significant because periodontal disease is under-treated, and highly prevalent among adults at risk of CVD. Even a small beneficial effect of periodontal treatment on CVD risk can be important.

    Full Text Available Scope: Diagnosis of periodontal disease is firstly based on clinical signs and symptoms, however, when bone destruction is involved, radiographic examination is the most conclusive diagnosis method to be recommended. Even if the 2D radiography is most frequently used for such a diagnosis, CBCT (Cone Beam Computed Technology comes to complete, help and provide new data on diagnosing periodontal lesions. The present study reviews original articles and synthesis papers issued between 2004-2014 in ScienceDirect, EBSCO, PubMed. Conclusions: In periodontology, CBCT appears as superior to 2D radiographies, being especially useful in the diagnosis of branch craters, lesions, vestibular and oral bone destructions, offering to the patient highly superior benefist compared to the risks caused by exposure.

    Full Text Available We attempted in this study to determine the thyroid hormone levels in 45 adult chronic kidney disease (CKD patients and 45 ageand sex-matched healthy subjects as controls. The serum thyroid hormone levels were measured by a radioimmunoassay. Serum concentrations of creatinine, urea, electrolytes and total proteins and albumin were measured as well. There was a significant decrease in the levels of serum total T3, total T4 and total protein and albumin levels in CKD patients when compared with the controls. There was a significant increase in the level of thyroid stimulating hormone in the CKD patients compared with the controls. Our study suggests that CKD leads to significant changes in the thyroid hormone levels, which need to be interpreted carefully in these patients.

    Full Text Available Abstract Background Meningococcal meningitis is a major cause of disease worldwide, with frequent epidemics particularly affecting an area of sub-Saharan Africa known as the “meningitis belt”. Neisseria meningitidis group A (MenA is responsible for major epidemics in Africa. Recently W-135 has emerged as an important pathogen. Currently, the strategy for control of such outbreaks is emergency use of meningococcal (MC polysaccharide vaccines, but these have a limited ability to induce herd immunity and elicit an adequate immune response in infant and young children. In recent times initiatives have been taken to introduce meningococcal conjugate vaccine in these African countries. Currently there are two different types of MC conjugate vaccines at late stages of development covering serogroup A and W-135: a multivalent MC conjugate vaccine against serogroup A,C,Y and W-135; and a monovalent conjugate vaccine against serogroup A. We aimed to perform a structured assessment of these emerging meningococcal vaccines as a means of reducing global meningococal disease burden among children under 5 years of age. Methods We used a modified CHNRI methodology for setting priorities in health research investments. This was done in two stages. In the first stage we systematically reviewed the literature related to emerging MC vaccines relevant to 12 criteria of interest. In Stage II, we conducted an expert opinion exercise by inviting 20 experts (leading basic scientists, international public health researchers, international policy makers and representatives of pharmaceutical companies. They answered questions from CHNRI framework and their “collective optimism” towards each criterion was documented on a scale from 0 to 100%. Results For MenA conjugate vaccine the experts showed very high level of optimism (~ 90% or more for 7 out of the 12 criteria. The experts felt that the likelihood of efficacy on meningitis was very high (~ 90%. Deliverability

    Full Text Available Background: On 3 July 2009, new law pertaining to occupational diseases (ODs became effective in Poland. The article presents opinions of the representatives of the 1st degree ODs certification entities and sanitary inspectorates on the changes in OD law and the problems that may cause difficulties and/or certification errors. Material and Methods: A questionnaire study was performed covering representatives of 20 voivodeship occupational medicine centers and 40 national district sanitary inspectorates. We received 57 completed questionnaires which were analyzed. Results: Positive opinions were expressed on changes in procedures on reporting suspected occupational diseases (50%, keeping time limits for diagnosing ODs (89.2%, and changes pertaining to entities responsible for certifying infectious ODs (92.9%. A large group of respondents (66.7% was in favor of conducting jointly an occupational exposure risk analysis by occupational medicine physicians and occupational health and safety practitioners and/or sanitary inspectors. One-third of the respondents declared that changes in the list of ODs had no influence on the certification procedure. Conclusions: New law has improved the existing procedure of ODs certification. There is a need to elaborate detailed diagnostic guidelines on and criteria for ODs identification and recognition. A panel of experts should be established by the Ministry of Health to track the latest advancements in medicine and to update the list of ODs. Conducting jointly an occupational exposure risk analysis by occupational medicine physicians and occupational health and safety practitioners and/or sanitary inspectors should become a standard.

    2016-01-01

    Studies of cerebrospinal fluid (CSF) biomarkers in Alzheimer's disease (AD) have indicated that much of the variability observed in the biomarkers may be due to measurement error. Biomarkers are often obtained with measurement error, which may make the diagnostic biomarker appear less effective than it truly is. In the Alzheimer's Disease Neuroimaging Initiative (ADNI) database, technical replicates of CSF biomarkers are available; the National Alzheimer's Coordinating Center database contains longitudinal replicates of CSF biomarkers. We focus on the area under the receiver operating characteristic curve (AUC) as the measure of diagnostic effectiveness for differentiating AD from normal cognition using CSF biomarkers and compare AUC estimates obtained by a more standard, naïve method (which uses a single observation per subject and ignores measurement error) to a maximum likelihood (ML) based method (which uses all replicates per subject and adjusts for measurement error). The choice of analysis method depends upon the noise to signal ratio (i.e., the magnitude of the measurement error variability relative to the true biomarker variability); moderate to high ratios may significantly bias the naïve AUC estimate, and the ML-based method would be preferred. The noise to signal ratios were low for the ADNI biomarkers but high for the tTau and pTau biomarkers in NACC. Correspondingly, the naïve and ML-based AUC estimates were nearly identical in the ADNI data but dissimilar for the tTau and pTau biomarkers in the NACC data. Therefore, using the naïve method is adequate for analysis of CSF biomarkers in the ADNI study, but the ML method is recommended for the NACC data.

    The aim of this SPECT study was to determine the initial abnormality and longitudinal changes in regional cerebral blood flow (rCBF) in early Alzheimer's disease (AD) using statistical parametric mapping (SPM). rCBF was noninvasively measured using (99m)Tc-ethyl cysteinate dimer SPECT in 32 patients complaining of mild cognitive impairment, with a Mini-Mental State Examination score more than 24 at the initial study, and 45 age-matched healthy volunteers. All patients satisfied the diagnostic criteria of AD during the follow-up period of at least 2 y. Follow-up SPECT studies were performed on the patients at a mean interval of 15 mo. We used the raw data (absolute rCBF parametric maps) and the adjusted rCBF images of relative flow distribution (normalization of global cerebral blood flow [CBF] for each subject to 50 mL/100 g/min with proportional scaling) to compare these groups with SPM. In the baseline study, the adjusted rCBF was significantly and bilaterally decreased in the posterior cingulate gyri and precunei of patients compared with healthy volunteers. In the follow-up study, selected reduction of the adjusted rCBF was observed in the left hippocampus and parahippocampal gyrus. These areas showed the most prominent reduction in absolute rCBF on each occasion. Moreover, further decline of the absolute rCBF was longitudinally observed in extensive areas of the cerebral association cortex. SPM analysis showed the characteristic early-AD rCBF pattern of selective decrease and longitudinal decline, which may be overlooked by a conventional region-of-interest technique with observer a priori choice and hypothesis. This alteration in rCBF may closely relate to the pathophysiologic process of this disease.

    The Japanese Orthopaedic Association Hip Score is widely used in Japan, but this tool is designed to reflect the viewpoint of health-care providers rather than that of patients. In gauging the effect of medical therapies in addition to clinical results, it is necessary to assess quality of life (QOL) from the viewpoint of patients. However, there is no tool evaluating QOL for Japanese patients with hip-joint disease. With the aim of more accurately classifying QOL for Japanese patients with hip-joint disease, we prepared a questionnaire with 58 items for the survey derived from 464 opinions obtained from approximately 100 Japanese patients with hip-joint disease and previously devised evaluation criteria. In the survey, we collected information on 501 cases, and 402 were subjected to factor analysis. From this, we formulated three categories-movement, mental, and pain-each comprising 7 items, for a total of 21 items to be used as evaluation criteria for hip-joint function. The Cronbach's α coefficients for the three categories were 0.93, 0.93, and 0.95, respectively, indicating the high reliability of the evaluation criteria. The 21 items included some related to the Asian lifestyle, such as use of a Japanese-style toilet and rising from the floor, which are not included in other evaluation tools. This self-administered questionnaire may become a useful tool in the evaluation of not only Japanese patients, but also of members of other ethnic groups who engage in deep flexion of the hip joint during daily activities.

    Objective: the present study was aimed at demonstrating the value of computed tomography enterography (CT enterography) and how this imaging method can be useful in the diagnostic elucidation and assessment of patients with small bowel diseases. Materials and methods: retrospective evaluation of 35 patients submitted to CT enterography in a 16-row multidetector CT equipment from May/2008 to March/2009. All the patients received intravenous and neutral oral iodinated contrast agents (polyethylene glycol). Main indications were: Crohn's disease, diarrhea of undetermined origin and suspicion of neoplasia. Results: a good correlation was observed between CT enterography findings and clinical, laboratory and endoscopic data related to the disease activity in patients with Crohn's disease. In 15 cases alterations compatible with Crohn's disease were identified, nine of them suggesting disease activity. A diagnosis was achieved in the majority of the patients with diarrhea. Carcinoid tumors were identified in two patients. Conclusion: CT enterography is a simple and effective method in the evaluation of inflammatory/neoplastic small bowel diseases, particularly in cases of Crohn's disease, indicating disease activity. One of the main advantages of this method is the possibility of evaluating associated mesenteric and extraintestinal alterations (author)

    Full Text Available Abstract Oral complications of RA may include temporomandibular joint disorders, mucosa alterations and symptoms of dry mouth. The aim of this study was to evaluate the salivary gland function of subjects with rheumatoid arthritis (RA comparing it to healthy controls. Subjects with other systemic conditions known to affect salivary functions were excluded. A questionnaire was applied for the evaluation of xerostomia. Resting and chewing-stimulated salivary flow rates (SFR were obtained under standard conditions. There were 145 subjects included of the study (104 RA and 38 controls. About 66.7% of the RA subjects and 2.4% in control group presented xerostomia. The median resting SFR were 0.24 ml/min for RA subjects and 0.40 mL/min for controls (p = 0.04. The median stimulated SFR were 1.31 mL/min for RA subjects and 1.52 ml/min for controls (p = 0.33. No significant differences were found between resting and stimulated SFR of RA subjects not using xerogenic medications and controls. There was significantly higher number of subjects presenting hyposalivation in the RA group than among controls, even when subjects using xerogenic medications were eliminated from the analysis. In conclusion, hyposalivation and xerostomia were more frequent among RA subjects not using xerogenic medication than among controls, although there were no significant differences in the median SFR between groups.

    Recent cases of donor-derived infections raise the question of how best to screen donors without excessive restriction of the donor pool. The New York Organ Donor Network (NYODN) established an Infectious Diseases Working Group (IDWG) in 2008, which established an on-call schedule of voluntary transplant infectious disease physicians to provide remote evaluations for donors at increased risk for disease transmission. Data were reviewed from 40 available IDWG evaluations from 2008 to 2011. Eighteen cases (45%) were considered to be at unacceptable risk for infection transmission. Sixteen of these cases were excluded from donation secondary to IDWG recommendation; there was limited recipient center interest in the remaining two cases. Approximately 22 (55%) cases were categorized by the IDWG as acceptable, with 14 proceeding to recovery of 49 organs. IDWG physician recommendations were conveyed to recipient centers, and screening guidelines for donors were revised based on the IDWG experiences. Establishment of a donation service area disease transmission evaluation service is a valuable program for donor screening and may promote dissemination of more detailed donor information to recipient centers.

    Examinations using ionizing radiation are frequently used in the evaluation of disease activity in children affected by idiopathic inflammatory bowel disease (IBD). To develop an MR imaging protocol without the need for fluoroscopic insertion of an enteral tube and to assess the disease activity in children with IBD. Included in the study were 37 children (22 girls and 15 boys; age range 7-15 years, mean 11.67 years) with IBD who underwent MR imaging of the small bowel. Of these 37 children, 32 had Crohn disease and 5 had indeterminate colitis. A water solution containing herbal fibres was administered orally or through a nasogastric tube. Patients were imaged on a 1.5-T MR scanner with T1-weighted and {tau}2-weighted sequences followed by a dynamic study using 3-D T1-W images after intravenous administration of gadolinium. The percentage enhancement of the bowel wall was significantly increased in patients with abnormal C-reactive protein (CRP) values compared to patients with CRP values in the normal range (P<0.001). A relatively weak but significant correlation between percentage enhancement of the bowel wall and CRP values was noted during all phases of enhancement. This MR imaging protocol is a safe and well-tolerated method for evaluating disease activity and extraintestinal manifestations of IBD in children. (orig.)

    With the increasing prevalence of obesity, clinicians are now facing a growing population of patients with specific features of clinical presentation, diagnostic challenges, and interventional, medical, and surgical management. After briefly discussing the effect of obesity on atherosclerotic burden in this review, we will focus on strategies clinicians might use to ensure better outcomes when performing revascularization in obese and severely obese patients. These patients tend to present comorbidities at a younger age, and their anthropometric features might limit the use of traditional cardiovascular risk stratification approaches for ischemic disease. Alternative techniques have emerged, especially in nuclear medicine. Positron emission tomography-computed tomography might be the diagnostic imaging technique of choice. When revascularization is considered, features associated with obesity must be considered to guide therapeutic strategies. In percutaneous coronary intervention, a radial approach should be favoured, and adequate antiplatelet therapy with new and more potent agents should be initiated. Weight-based anticoagulation should be contemplated if needed, with the use of drug-eluting stents. An "off-pump" approach for coronary artery bypass grafting might be preferable to the use of cardiopulmonary bypass. For patients who undergo bilateral internal thoracic artery grafting, harvesting using skeletonization might prevent deep sternal wound infections. In contrast to percutaneous coronary intervention, lower surgical bleeding has been observed when lean body mass is used for perioperative heparin dose determination.

    Pathologic studies of the heart in patients with Kawasaki disease (KD) revealed vasculitis, valvulitis, myocarditis, and pericarditis. However, there have been no studies on the quantitative determination of multi-site echogenicity of the heart in KD patients. It is also undetermined whether the degree of echogenicity of each site of the heart in patients with KD might be related to the response to intravenous immunoglobulin (IVIG) treatment. In 81 KD patients and 30 control subjects, we prospectively analyzed echogenicity of the heart. Echogenicity was measured in four sites: coronary artery wall (CAW), mitral valve (MV), papillary muscle (PM), and ascending aortic wall (AAo wall) by the calibrated integrated backscatters (cIBs). The cIB values of all measurement sites at acute phase in KD patients were significantly higher than those in control subjects (KD patients vs control subjects; CAW, 19.8 ± 6.2 dB vs 14.5 ± 2.0 dB, p IVIG nonresponders were significantly higher than those in responders. Conclusion: Echogenicity of the heart in KD patients at the acute phase increased not only in the coronary artery wall but also in other parts of the heart. Echogenicity of CAW might be helpful in determining the unresponsiveness of IVIG treatment.

    Nephrolithiasis (LIT) is more prevalent in patients with autosomal dominant polycystic kidney disease (ADPKD) than in the general population. Renal ultrasonography may underdetect renal stones because of difficulties imposed by parenchymal and/or cyst wall calcifications. A total of 125 patients with ADPKD underwent ultrasonography and unenhanced computed tomography (CT) scan, routine blood chemistry, and spot and 24-h urine collections. CT scan detected calculi in 32 patients, including 20 whose previous ultrasonography revealed no calculi. The percentage of hypocitraturia was high but not statistically different between patients with ADPKD+LIT or ADPKD. Hyperuricosuria and distal renal tubular acidosis were less prevalent but also did not differ between groups, whereas hyperoxaluria was significantly higher in the former. Hypercalciuria was not detected. Renal volume was significantly higher in patients with ADPKD+LIT versus ADPKD, and a stepwise multivariate logistic regression analysis showed that a renal volume >or=500 ml was a significant predictor of LIT in patients with ADPKD and normal renal function, after adjustments for age and hypertension. CT scan was better than ultrasonography to detect LIT in patients with ADPKD. Larger kidneys from patients with ADPKD were more prone to develop stones, irrespective of the presence of metabolic disturbances.

    Full Text Available Aim: To find out the prevalence of hydatidosis and the number of livers condemned due to this disease using retrospective data from municipal slaughterhouse in Keren, Eritrea. Materials and Methods: A retrospective data of ten years (1999 to 2008 on slaughtered goats and sheep was collected from Keren Municipal slaughterhouse, Anseba Zone of Eritrea. The data was analyzed for the prevalence of hydatidosis and the number of livers condemned. Besides, condemned livers from sheep and goats due to the presence of hydatid cysts were collected (September to December, 2008, and from March to July, 2009 for gross examination and microscopic pathology. Result: Our findings indicated that among the parasitic diseases encountered in the slaughtered animals, hydatid cysts were the most prevalent ones. Conclusion: This study has depicted that the major contributor for liver condemnation was hydatidosis. Moreover, the study has shown that the trend of the prevalence of hydatidosis is increasing and this warrants immediate intervention for its control.

    Congenital heart disease (CGHD) can be considered a chronic disease for many patients. To adopt a healthy lifestyle and to avoid complications, patients with CGHD and their parents need to have good knowledge of the heart defect and its consequences. The aims of this study were to evaluate patient and parental knowledge of CGHD and to explore the related factors of their respective disease knowledge. This study included 116 dyads of adolescents with CGHD (43.1% male adolescents; aged 12-18 years) and one of their parents (79.3% mothers; median age, 46 years). All participants completed the Leuven Knowledge Questionnaire for Congenital Heart Disease, and then we calculated a correct rate score to determine the overall disease knowledge of the respondents. The correct rate score was 38.8% for adolescents with CGHD and 51.4% for parents (t = 7.69; P parents was their educational level (standardized estimate = 6.160, P adolescents, knowledge was determined by age (standardized estimate = 2.242, P = .002) and parental knowledge (standardized estimate = 0.311, P parents have significantly greater disease knowledge than their children do, the level of knowledge in both parents and adolescents is suboptimal. Because parents' knowledge influenced their adolescents' knowledge, educational interventions should target both adolescent patients and parents. Transition programs can play a pivotal role in this respect.

    The diagnostic efficacy of Fasciola gigantica adult worm vomit (AWV) preparation in diagnosis of human fasciolosis was evaluated using conventional enzyme-linked immunosorbent assay (ELISA) and Falcon assay screening test (FAST)-ELISA in comparison with F. gigantica adult total soluble extract (TSE). Sera of fasciolosis patients, patients with other parasitic diseases (hydatid disease, schistosomiasis, toxoplasmosis, and amebiasis), and sera of healthy individuals were enrolled in this study. The results showed that the sensitivity of both conventional ELISA and FAST-ELISA was improved from 95 % using TSE to 100 % when using AWV. The specificity of conventional ELISA was 93.3 % using TSE and increased to 96.7 % using AWV. The specificity of FAST-ELISA using TSE was 96.7 % and became 100 % AWV antigen. The diagnostic accuracy of conventional ELISA was 94 % using TSE and increased to 98 % using AWV. The diagnostic accuracy of FAST-ELISA was 96 % using TSE and increased to 100 % using AWV. It is concluded that both TSE and AWV antigenic preparations are efficient for use in the serodiagnosis of human fasciolosis.

    Microcirculation disturbances have been associated to most of the cardiovascular risk factors as well as to multiple inflammatory diseases. However, whether these abnormalities are specifically augmented in patients with coronary heart disease is still unknown. We aimed to evaluate if there is a relationship between the presence of coronary heart disease and the existence of functional and structural capillary abnormalities evaluated in the cutaneous microcirculation by videocapillaroscopy. Two matched samples of 30 participants with and without coronary heart disease but with similar clinical and anthropometric characteristics were evaluated by videocapillaroscopy at the dorsal skin of the third finger of the non-dominant hand. We calculated basal capillary density as well as capillary density after a period of arterial and venous occlusion in order to evaluate functionality and maximum capillary density. We also measured capillary recruitment. Microvascular capillary density at rest was significantly lower in patients suffering from coronary heart disease than in controls. This fact was also found after dynamic tests (arterial and venous occlusion), suggesting functional impairments. Capillary recruitment of the samples was not different in our sample. In our study, patients with coronary heart disease exhibit functional and structural microvascular disturbances. Although this is a very preliminary study, these findings open the door for further studying the microvascular functionality in coronary patients and how it relates to the response to treatment and/or the prognosis of the disease.

    Full Text Available The larva of cestodes belonging to the Echinococcus granulosus sensu lato (s.l. complex causes cystic echinococcosis (CE. It is a globally distributed zoonosis with significant economic and public health impact. The most immunogenic and specific Echinococcus-genus antigen for human CE diagnosis is antigen B (AgB, an abundant lipoprotein of the hydatid cyst fluid (HF. The AgB protein moiety (apolipoprotein is encoded by five genes (AgB1-AgB5, which generate mature 8 kDa proteins (AgB8/1-AgB8/5. These genes seem to be differentially expressed among Echinococcus species. Since AgB immunogenicity lies on its protein moiety, differences in AgB expression within E. granulosus s.l. complex might have diagnostic and epidemiological relevance for discriminating the contribution of distinct species to human CE. Interestingly, AgB2 was proposed as a pseudogene in E. canadensis, which is the second most common cause of human CE, but proteomic studies for verifying it have not been performed yet. Herein, we analysed the protein and lipid composition of AgB obtained from fertile HF of swine origin (E. canadensis G7 genotype. AgB apolipoproteins were identified and quantified using mass spectrometry tools. Results showed that AgB8/1 was the major protein component, representing 71% of total AgB apolipoproteins, followed by AgB8/4 (15.5%, AgB8/3 (13.2% and AgB8/5 (0.3%. AgB8/2 was not detected. As a methodological control, a parallel analysis detected all AgB apolipoproteins in bovine fertile HF (G1/3/5 genotypes. Overall, E. canadensis AgB comprised mostly AgB8/1 together with a heterogeneous mixture of lipids, and AgB8/2 was not detected despite using high sensitivity proteomic techniques. This endorses genomic data supporting that AgB2 behaves as a pseudogene in G7 genotype. Since recombinant AgB8/2 has been found to be diagnostically valuable for human CE, our findings indicate that its use as antigen in immunoassays could contribute to false negative

    : Niemann-Pick disease type A (NPA) is a lysosomal storage disease caused by mutations in the SMPD1 gene that encodes acid sphingomyelinase (ASM). Deficiency in ASM function results in lysosomal accumulation of sphingomyelin and neurodegeneration. Currently, there is no effective treatment for NPA. To accelerate drug discovery for treatment of NPA, we generated induced pluripotent stem cells from two patient dermal fibroblast lines and differentiated them into neural stem cells. The NPA neural stem cells exhibit a disease phenotype of lysosomal sphingomyelin accumulation and enlarged lysosomes. By using this disease model, we also evaluated three compounds that reportedly reduced lysosomal lipid accumulation in Niemann-Pick disease type C as well as enzyme replacement therapy with ASM. We found that α-tocopherol, δ-tocopherol, hydroxypropyl-β-cyclodextrin, and ASM reduced sphingomyelin accumulation and enlarged lysosomes in NPA neural stem cells. Therefore, the NPA neural stem cells possess the characteristic NPA disease phenotype that can be ameliorated by tocopherols, cyclodextrin, and ASM. Our results demonstrate the efficacies of cyclodextrin and tocopherols in the NPA cell-based model. Our data also indicate that the NPA neural stem cells can be used as a new cell-based disease model for further study of disease pathophysiology and for high-throughput screening to identify new lead compounds for drug development. Currently, there is no effective treatment for Niemann-Pick disease type A (NPA). To accelerate drug discovery for treatment of NPA, NPA-induced pluripotent stem cells were generated from patient dermal fibroblasts and differentiated into neural stem cells. By using the differentiated NPA neuronal cells as a cell-based disease model system, α-tocopherol, δ-tocopherol, and hydroxypropyl-β-cyclodextrin significantly reduced sphingomyelin accumulation in these NPA neuronal cells. Therefore, this cell-based NPA model can be used for further study of

    De Quervain disease is a stenosing condition of the sheath of the abductor pollicis longus and extensor pollicis brevis tendons at the radial styloid process. Previous studies consistently reported that the pathological change of this condition is thought to be primarily an extensor retinaculum thickened by fibrosis and angiogenesis instead of inflammation. Contradictorily, the conservative treatment for de Quervain disease is anti-inflammatory medication. The inflammatory response may be involved in this disease; however, there is no present study directly evidencing whether the inflammatory responses exist in de Quervain disease or not. The histopathology of de Quervain disease is yet to be elucidated clearly. To grade all specimens in the different stages and characterize specific inflammatory cell and factors to examine whether inflammatory response is involved in de Quervain disease. Retinaculum samples were collected from 13 patients with de Quervain disease after surgery. The specimens were evaluated histologically by collagen structure grading and immunohistochemically by quantifying the presence of neutrophil elastase, macrophages, cyclooxygenase, and vascular endothelium. Neutrophil elastase and cyclooxygenase occur in the de Quervain disease retinaculum and increased with the grade of collagen structure. After angiogenesis, macrophage infiltration occurs in the grade II matrix worse than grade III matrix. Inflammation is present in de Quervain disease. This study provides direct evidence for inflammatory cell and infiltration factors and offer valuable clues for specific pharmacological therapies for de Quervain disease.

    Endoscopy is the gold standard to assess disease severity in inflammatory bowel disease, although it is an invasive procedure. Clinical activity and biological markers have been routinely used to determine disease activity in a non-invasive manner. The aim of this study was to determine concordance between common biological markers (C reactive protein, orosomucoid, erythrocyte sedimentation rate, fibrinogen, platelets, leukocytes, neutrophils and haemoglobin) and clinical activity in inflammatory bowel disease. Consecutive patients with inflammatory bowel disease were included. Clinical activity was evaluated according to the Harvey-Bradshaw index in Crohn's disease and to the partial Mayo score in ulcerative colitis. Serum concentrations of the different biomarkers were analysed. Concordance between clinical activity and elevation of the serological biomarkers was determined using the kappa statistic. In total, 350 patients were included (median age 46 years, Crohn's disease 59%). Eleven percent of patients had clinical activity. Crohn's disease patients had mild clinical activity in 44% of cases, moderate disease in 44% and only 12% of patients had severe clinical activity. In ulcerative colitis, patients had mild, moderate and severe clinical activity in 50, 42 and 8% of cases, respectively. None of the biomarkers included had an acceptable concordance with clinical activity (kappa statistic ≤ 0.30). Concordance between serological biomarkers and clinical activity in inflammatory bowel disease is remarkably low. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

    We have presented a novel scolicidal agent made from fluoride-containing bioactive glass (FBG). The samples were characterized by XRD and the ion release behavior of the samples was evaluated at 37°C. The scolicidal activity, cellular response and antibacterial activity and biocompatibility of the different concentrations of the FBG (ranging from 0.5 to 2 mg ml(-1)) were evaluated in vitro and in vivo. The results showed an easy diffusion of the fluoride through the glass matrix in an F concentration-dependent manner. The FBG showed an intensive scolicidal property, so that toxicity effect begun from 5 min and the samples with 20, 10, 5 and 0% fluoride showed 98±2, 93±5.8, 76.2±6 and 5.8±1.7% scolicidal activity, respectively, after 8h exposing time. Our data revealed that scolicidal activity of the FBG increased with the increase of F ratio and concentrations of the bioactive glass. On the other hand, all the synthesized FBG samples found to be cyto-biocompatible when tested in vitro (MTT and LDH assays) and in vivo (no significant infiltration of inflammatory cells compared with control, p>0.05), and antibacterial against Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa. The results demonstrated that the synthesized FBG might have a potential application in prevention of post-surgery infections, especially hydatidosis. Copyright © 2015 Elsevier B.V.

    To consider the methods available to model Alzheimer's disease (AD) progression over time to inform on the structure and development of model-based evaluations, and the future direction of modelling methods in AD. A systematic search of the health care literature was undertaken to identify methods to model disease progression in AD. Modelling methods are presented in a descriptive review. The literature search identified 42 studies presenting methods or applications of methods to model AD progression over time. The review identified 10 general modelling frameworks available to empirically model the progression of AD as part of a model-based evaluation. Seven of these general models are statistical models predicting progression of AD using a measure of cognitive function. The main concerns with models are on model structure, around the limited characterization of disease progression, and on the use of a limited number of health states to capture events related to disease progression over time. None of the available models have been able to present a comprehensive model of the natural history of AD. Although helpful, there are serious limitations in the methods available to model progression of AD over time. Advances are needed to better model the progression of AD and the effects of the disease on peoples' lives. Recent evidence supports the need for a multivariable approach to the modelling of AD progression, and indicates that a latent variable analytic approach to characterising AD progression is a promising avenue for advances in the statistical development of modelling methods.

    Full Text Available The aim of this paper is to analyze the a priori dietary indexes used in the studies that have evaluated the role of the Mediterranean Diet in influencing the risk of developing cardiovascular disease. All the studies show that this dietary pattern protects against cardiovascular disease, but studies show quite different effects on specific conditions such as coronary heart disease or cerebrovascular disease. A priori dietary indexes used to measure dietary exposure imply quantitative and/or qualitative divergences from the traditional Mediterranean Diet of the early 1960s, and, therefore, it is very difficult to compare the results of different studies. Based on real cultural heritage and traditions, we believe that the a priori indexes used to evaluate adherence to the Mediterranean Diet should consider classifying whole grains and refined grains, olive oil and monounsaturated fats, and wine and alcohol differently.

    1989-08-01

    A prospective study was undertaken on 204 consecutive patients comparing low flip angle gradient-echo and T1-weighted spin-echo techniques in the MR evaluation of cervical extradural disease. Four patient groups were studied with varying gradient-echo TEs (6 or 13 msec) and flip angles (10 degrees or 60 degrees). Images were evaluated independently for contrast behavior and anatomy, then directly compared for conspicuity of lesions. The FLASH sequences (especially with a 10 degrees flip angle) produced better conspicuity of disease in half the imaging time. T1-weighted spin-echo sequences were more sensitive to marrow changes and intradural disease. The short TE sequence (6 msec) did not produce any diagnostic advantage over the longer TE sequence (13 msec). A fast and sensitive MR examination for cervical extradural disease combines a sagittal T1-weighted spin-echo acquisition with sagittal and axial FLASH 10 degrees sequences.

    To correlate magnetic resonance imaging (MRI) assessment of disease activity in patients with Takayasu's arteritis with the Indian Takayasu's activity score (ITAS). We prospectively assessed 20 patients with Takayasu's arteritis from November 2010 to September 2011. We found a statistically significant association between MRI assessment of disease activity and ITAS with a P-value of 0.01. The MRI features suggesting active disease included wall thickening and enhancement. We also analyzed the association between MRI and clinical assessment which was also statistically significant at P = 0.037. Our study suggests that there is an association between MRI assessment of disease activity and the ITAS. MRI evaluation of disease activity of Takayasu's arteritis therefore goes hand in hand with ITAS 2010, ITAS - A, erythrocyte sedimentation rate and C-reactive protein. However this needs further investigation from future studies using serial assessments. © 2017 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

    The purpose of the study was to elucidate characteristics of depression in Parkinson's disease (PD). Fifty-eight PD patients were evaluated with Zung's Self-Rating Depression Scale (SDS) and the Unified Parkinson's Disease Rating Scale (UPDRS). Scores for "suicidal ideation" on the SDS correlated with posture and gait disturbances on the UPDRS. Twenty-six patients with spinocerebellar degeneration (SCD) were also evaluated with the SDS. SDS scores for "indecisiveness" and "constipation" were significantly higher in PD patients than SCD patients. Our results suggest that depression is common in disabled persons but PD patients might have a characteristic clinical presentation.

    This study evaluates the antitumor immune response induced by human hydatic cyst fluid (HCF) in an animal model of colon carcinoma. We found that anti-HCF antibodies were able to identify cell surface and intracellular antigens in CT26 colon cancer cells. In prophylactic tumor challenge experiments, HCF vaccination was found to be protective against tumor formation for 40% of the mice (P = 0.01). In the therapeutic setting, HCF vaccination induced tumor regression in 40% of vaccinated mice (P = 0.05). This vaccination generated memory immune responses that protected surviving mice from tumor rechallenge, implicating the development of an adaptive immune response in this process. We performed a proteomic analysis of CT26 antigens recognized by anti-HCF antibodies to analyze the immune cross-reactivity between E. granulosus (HCF) and CT26 colon cancer cells. We identified two proteins: mortalin and creatine kinase M-type. Interestingly, CT26 mortalin displays 60% homology with E. granulosus hsp70. In conclusion, our data demonstrate the capacity of HCF vaccination to induce antitumor immunity which protects from tumor growth in an animal model. This new antitumor strategy could open new horizons in the development of highly immunogenic anticancer vaccines. PMID:24023528

                A 48-year-old man was admitted to our outpatient clinic with low back and right leg pain for 1 year. Lumbar spinal movements were painful and the pain radiated to his right posterolateral thigh. There was no weakness and numbness in both lower limbs but he had difficulty in load transfer during walking and therefore had ambulation difficulty. Tendon reflexes, and muscle strength examinations were normal. There was a slightly swelling at the right lumbar paravertebral region of spine by palpation. Routine blood tests were normal. Lumbar magnetic resonance examination (MRI was requested for clear evaluation of lower back structures. In MRI, we found a 8 × 5 cm multicystic mass at the level of L3–S3 located at the right paravertebral muscle. After this diagnosis, the patient began receiving albendazol.  Total cyst resection was performed and the histopathological examination confirmed hydatic cyst.

    Degenerative joint disease is common in cats, with signs of pain frequently found on orthopedic examination and radiographs often showing evidence of disease. However, understanding of the pathophysiology of degenerative joint disease and associated pain remains limited. Several cytokines have been identified as having a role in pain in humans, but this has not been investigated in cats. The present study was performed to use a multiplex platform to evaluate the concentration of 19 cytokines and chemokines in serum samples obtained from cats with and without degenerative joint disease and associated pain. Samples from a total of 186 cats were analyzed, with cats representing a range of severity on radiographic and orthopedic evaluations and categorized by degenerative joint disease scores and pain scores. Results showed that cats with higher radiographic degenerative joint disease scores have higher serum concentrations of IL-4 and IL-8, while cats with higher orthopedic exam pain scores have higher concentrations of IL-8, IL-2, and TNF-α; increased concentration of IL-8 in degenerative joint disease and pain may be confounded by the association with age. Discriminant analysis was unable to identify one or more cytokines that distinguish between groups of cats classified based on degenerative joint disease score category or pain score category. Finally, cluster analysis driven by analyte concentrations shows separation of groups of cats, but features defining the groups remain unknown. Further studies are warranted to investigate any changes in cytokine concentrations in response to analgesic therapies, and further evaluate the elevations in cytokine concentrations found here, particularly focused on studies of local cytokines present in synovial fluid.

    Chronic kidney disease is a public health problem with an increasing incidence and prevalence, poor outcomes, and high cost. Patient involvement forms the keystone in the management of chronic kidney disease. This study evaluated effects of pharmacist-provided counseling in dialysis patients in terms of their knowledge, attitude, and practice outcomes. A total of 64 patients with chronic kidney disease were enrolled into the prospective, pre-post study based on the inclusion and exclusion criteria. The knowledge, attitude, and practice of patients regarding chronic kidney disease were assessed and recorded via baseline questionnaire. Case group patients were counseled regarding chronic kidney disease, their medication, diet, and lifestyle, and they were also provided with informative leaflet, whereas in the control group patients, the pharmacist did not intervene. After 1-month intervention, knowledge, attitude, and practice scores of patients of both groups were measured using the same knowledge, attitude, and practice questionnaire. Effectiveness of counseling on case group patients was evaluated by comparing the mean knowledge, attitude, and practice scores before and after counseling by paired t-test. Mean knowledge, attitude, and practice scores before intervention were 8.16 ± 4.378, 38.19 ± 3.217, and 6.69 ± 0.896, respectively, and these scores were changed to 13.75 ± 3.510, 38.78 ± 3.035, and 6.91 ± 0.777, respectively, after the intervention (p knowledge, attitude, and practice of patients toward the disease management.

    Dyspnea and exercise limitation are among the most common symptoms experienced by patients with various chronic lung diseases and are linked to poor quality of life. Our understanding of the source and nature of perceived respiratory discomfort and exercise intolerance in chronic lung diseases has increased substantially in recent years. These new mechanistic insights are the primary focus of the current review. Cardiopulmonary exercise testing (CPET) provides a unique opportunity to objectively evaluate the ability of the respiratory system to respond to imposed incremental physiological stress. In addition to measuring aerobic capacity and quantifying an individual's cardiac and ventilatory reserves, we have expanded the role of CPET to include evaluation of symptom intensity, together with a simple “non-invasive” assessment of relevant ventilatory control parameters and dynamic respiratory mechanics during standardized incremental tests to tolerance. This review explores the application of the new advances in the clinical evaluation of the pathophysiology of exercise intolerance in chronic obstructive pulmonary disease (COPD), chronic asthma, interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH). We hope to demonstrate how this novel approach to CPET interpretation, which includes a quantification of activity-related dyspnea and evaluation of its underlying mechanisms, enhances our ability to meaningfully intervene to improve quality of life in these pathologically-distinct conditions.

    Full Text Available Abstract Background The allocation of limited available healthcare resources demands an agreed rational allocation principle and the consequent priority setting. We assessed the association between economic evaluations of healthcare interventions published in Spain (1983-2008 and the disease burden in the population. Methods Electronic databases (e.g., PubMed/MEDLINE, SCOPUS, ISI Web of Knowledge, CRD, IME, IBECS and reports from health technology assessment agencies were systematically reviewed. For each article, multiple variables were recorded such as: year and journal of publication, type of study, health intervention targetted, perspective of analysis, type of costs and sources of information, first author's affiliation, explicit recommendations aimed at decision-making, and the main disease cause to which the intervention was addressed. The following disease burden measures were calculated: years of life lost (YLLs, years lived with disability (YLDs, disability-adjusted life years (DALYs, and mortality by cause. Correlation and linear regression models were fitted. Results Four hundred and seventy-seven economic evaluations were identified. Cardiovascular diseases (15.7%, infectious diseases (15.3%, malignant neoplasms (13.2%, and neuropsychiatric diseases (9.6% were the conditions most commonly addressed. Accidents and injuries, congenital anomalies, oral conditions, nutritional deficiencies and other neoplasms were the categories with a lowest number of studies (0.6% for each of them.

    New Zealand is free from all the major epidemic (Office International des Epizooties List A) diseases of animals and other important diseases, such as rabies and the transmissible spongiform encephalopathies. The once endemic conditions of sheep scab (Psoroptes ovis), bovine brucellosis (Brucella abortus), hydatids (Echinococcus granulosus) and Aujeszky's disease have been eradicated. Anthrax (Bacillus anthracis) is no longer considered endemic and Pullorum disease (Salmonella Pullorum) has effectively been eradicated from commercial poultry flocks. There are current control programmes for bovine tuberculosis (Mycobacterium bovis), enzootic bovine leucosis in dairy cattle, infectious bursal disease, ovine epididymitis (Brucella ovis), and caprine arthritis encephalitis. Historically, incursions by three important non-endemic diseases, contagious bovine pleuropneumonia, classical swine fever and scrapie, have been successfully eliminated. Any new occurrence of a serious exotic disease would be dealt with swiftly using powerful legislative authorities available for the purpose.

    Despite the high prevalence of voice disorders, the prevalence of laryngeal disease in the general population has not been determined using laryngoscopy. Factors considered associated with laryngeal disease have mostly been assessed using patient data or highly specific populations. We evaluated the prevalence of and associated factors with laryngeal diseases in the general Korean population. Cross-sectional study. We analyzed data from the Korea National Health and Nutrition Examination Survey for 19,039 participants assessed between 2008 and 2011. The prevalence, subjective discomforts rates of, and odd ratios (demographics, life-style factors, and diseases factors) for laryngeal disease were analyzed using simple and multiple logistic regression analyses, taking into account the complex sampling structure of the data. The top five laryngeal diseases in prevalence were laryngitis (3,513/100,000), vocal nodules (1,487/100,000), vocal polyp (404/100,000), Reinke's edema (347/100,000), and epiglottic cyst (296/100,000). Prevalence of laryngeal disease was higher in males, whereas the rate of subjective voice complaints was higher in females. In the logistic regression analysis, gender was not associated with laryngeal diseases after adjusting for other factors. We observed a positive association between low body mass index (BMI) and vocal nodules, and between high BMI and laryngitis, smoking and epiglottic cyst/hyperkeratosis/laryngeal cancer, higher education level and vocal nodules, and allergic rhinitis and vocal nodules/laryngitis/epiglottic cyst. The rate of subjective voice complaints and laryngeal disease co-occurrence was low. This study provides more reliable information of laryngeal disease because it includes participants without subjective complaints. 2b. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    Field evaluation of free-ranging wildlife requires the systematic documentation of a variety of environmental conditions and individual parameters of health and disease, particularly in the case of rare or endangered species. In addition, defined criteria are needed for the humane salvage of ill or dying animals. The purpose of this paper is to describe, in detail, the preparation, procedures, and protocols we developed and tested for the field evaluation of wild desert tortoises (Gopherus agassizii). These guidelines describe: preparations for the field, including developing familiarity with tortoise behavior and ecology, and preparation of standardized data sheets; journal notes to document background data on weather conditions, temperature, rainfall, locality, and historic and recent human activities; procedures to prevent the spread of disease and parasites; data sheets for live tortoises to record tortoise identification, location, sex, body measurements and activity; health profile forms for documenting and grading physical abnormalities of tortoise posture and movements, general condition (e.g., lethargy, cachexia), external parasites, and clinical abnormalities associated with shell and upper respiratory diseases; permanent photographic records for the retrospective analysis of progression and regression of upper respiratory and eye diseases, analysis of shell lesions and evaluation of growth and age; and indications and methods for salvaging ill or dying tortoises for necropsy evaluation. These guidelines, tested on 5,000 to 20,000 tortoises over a 10 to 27 yr period, were designed to maximize acquisition of data for demographic, ecological, health and disease research projects; to reduce handling and stress of individual animals; to avoid spread of infectious disease; to promote high quality and consistent data sets; and to reduce the duration and number of field trips. The field methods are adapted for desert tortoise life cycle, behavior, anatomy

    Full Text Available Crohn's disease affects any part of the GI tract, commonly the terminal ileum. To decrease radiation exposure we developed a low-radiation-dose unenhanced CT (modified small Bowel CT, MBCT to evaluate the small bowel using hyperdense oral contrast. Technique. MBCT was investigated in patients with pathologically proven Crohn's disease presenting with new symptoms from recurrent inflammation or stricture. After ethics board approval, 98 consecutive patients were retrospectively evaluated. Kappa values from two independent reviewers were calculated for presence of obstruction, active inflammation versus chronic stricture, and ancillary findings. Forty-two patients underwent surgery or colonoscopy within 3 months. Results. Kappa was 0.84 for presence of abnormality versus a normal exam and 0.89 for differentiating active inflammation from chronic stricture. Level of agreement for presence of skip areas, abscess formation, and fistula was 0.62, 0.75, and 0.78, respectively. In the subset with “gold standard” follow-up, there was 83% agreement. Conclusions. MBCT is a low-radiation technique with good to very good interobserver agreement for determining presence of obstruction and degree of disease activity in patients with Crohn's disease. Further investigation is required to refine parameters of disease activity compared to CT enterography and small bowel follow through.

    Refractory constipation is an extremely common problem in infants and children. The diagnostic suspicion of Hirschsprung disease often arises in this clinical setting. Diagnosing Hirschsprung disease can be difficult; however, excluding the diagnosis is much easier, only requiring the demonstration of ganglion cells in the distal rectum. The most common method for obtaining tissue from the rectum involves a blind suction biopsy. This technique has been complicated by serious adverse events, equipment malfunction, and inadequate specimens. Our goal was to evaluate the adequacy of specimens obtained with a flexible endoscope and jumbo biopsy forceps to rule out Hirschsprung disease in the child outside the newborn period. We retrospectively reviewed 668 rectal biopsies taken during 167 endoscopies on 156 patients being evaluated for Hirschsprung disease from 2001 to 2008 at the Baystate Medical Center Children's Hospital. Four biopsies were taken from each patient approximately 2.5 cm from the anal verge. Biopsies were obtained using a flexible endoscope and jumbo biopsy forceps. During the first 6 years the Olympus FB-50U-1 large cup fenestrated biopsy forceps was used. During the last 2 years the Boston Scientific Radial Jaw 4 Jumbo biopsy forceps was used instead. The Boston Scientific Radial Jaw 4 Jumbo biopsy forceps yielded adequate specimens 93% of the time, which surpassed most published results of other techniques. There were no complications reported. Obtaining rectal biopsies with a flexible endoscope and jumbo biopsy forceps is a safe and effective means to rule out the diagnosis of Hirschsprung disease in children.

    The aim of this study was to describe compliance with select quality indicators and assess organ-specific dysfunction in a childhood-onset systemic lupus erythematosus population by using a validated damage index and to evaluate associations between compliance with quality indicators and disease damage. A retrospective chart review was performed on patients diagnosed with systemic lupus erythematosus prior to age 18 followed at a single center in the USA from 1999 to 2012 (n = 75). Data regarding quality indicators and outcome variables, including the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index, were collected. The median disease duration was 3.8 years. The proportion of patients or patient-years in which care complied with the proposed quality measures was 94.4% for hydroxychloroquine use, 84.3% for vitamin D recommendation,75.8% for influenza vaccination (patient-years), 67.2% for meningococcal vaccination, 49.0% for ophthalmologic examination (patient-years), 31.7% for pneumococcal vaccination, and 28.6% for bone mineral density evaluation. Disease damage was present in 41.3% of patients at last follow-up, with an average damage index score of 0.81. Disease damage at last follow-up was associated with minority race/ethnicity (p = 0.008), bone mineral density evaluation (p = 0.035), and vitamin D recommendation (p = 0.018). Adherence to quality indicators in a childhood-onset systemic lupus erythematosus population is varied, and disease damage is prevalent. This study highlights the importance of quality improvement initiatives aimed at optimizing care delivery to reduce disease damage in pediatric lupus patients.

    Full Text Available Abstract Objective Evaluate the Neonatal Screening Program of the Health Secretariat of the State of Santa Catarina for sickle-cell disease, from January 2003 to December 2012, regarding program coverage and disease frequency. Methods Descriptive, observational, cross-sectional study with retrospective data collection. The variables analyzed were: number of live births in the State of Santa Catarina; number of screened children; number of children diagnosed with sickle-cell trait and sickle-cell disease; type of sickle-cell disease diagnosed; age at the time of sample collection, ethnicity/skin color, gender, and origin of children with sickle-cell disease. Descriptive measures and frequency tables were used for data analysis. Results During the study period, there were 848,833 live births and 730,412 samples were screened by the program, resulting in a coverage of 86.0%. There were 6173 samples positive for sickle-cell trait and 39 for sickle-cell disease. Among children with sickle-cell disease, the median age at the time of sample collection was 6 days. Regarding the ethnicity/skin color, 25 (64.1% children were white, seven were black, and seven others were not specified. The Midwest and the Highland (Planalto Serrano of Santa Catarina were the regions with the highest incidence of sickle-cell disease. Conclusion Coverage by the Neonatal Screening Program of Santa Catarina is good, but did not demonstrate an improvement trend over the years. The frequency of sickle-cell disease is low and lower than in the North, Northeast, and Midwest regions. The median age in days at the time of collection is older than the age recommended by the Ministry of Health.

    Although it is an enteroviral infectious disease, recent studies suggest that respiratory transmission might play a role in the transmission of hand, foot, and mouth disease (HFMD). We evaluated the transmission modes (respiratory and fecal-oral transmission) of HFMD among children using a case-control study in Guangdong, China. Our analyses suggested that fecal-oral transmission might be the principal transmission mode of HFMD among children in the study area, and handwashing habits of the children and their parents should be emphasized to control this infection.

    Children with Down syndrome (DS) have wide range of respiratory problems. Although underlying abnormalities in the respiratory system are important causes of morbidity and mortality in children with DS, particularly in the young, abnormalities in other organ systems may also impact respiratory function. A comprehensive evaluation of the child with DS and respiratory disease may prevent short-term morbidity and mortality, and reduce the incidence of complications in the long term. This review provides an overview of the various causes of respiratory disease, and insight into some of the newer therapies available to treat obstructive sleep apnea, in this population.

    Full Text Available ABSTRACT Background: Frontotemporal dementia (FTD is a heterogeneous clinicopathological syndrome whose early diagnosis is critical for developing management strategies. Objective: To analyze the variables associated with misdiagnosis in a group of patients with FTD, Alzheimer's disease (AD, and without neurodegenerative disorders (WND, all of whom were evaluated for behavioral and cognitive complaints. Methods: A case-control study with FTD (n=10, probable AD (n=10 and WND (n=10 patients was carried out. The studied variables were disease duration, reason for referral, former diagnosis, behavioral and cognitive symptoms at evaluation, MMSE at the specialist evaluation, and follow-up outcome. The data were analyzed by ANOVA with Bonferroni post-hoc and by Pearson's Chi-Square tests. Results: FTD patients and WND patients showed longer disease duration than AD patients; the main reasons for referral in the FTD group were behavioral, memory and memory plus language problems while all AD and 90% of the WND group were referred for memory. The FTD group had the highest rate of misdiagnosis and worst outcomes after the 12-month follow-up. The majority of AD and WND patients had memory symptoms, while FTD patients presented language (30%, memory and/or language (40% problems on the evaluation. Conclusion: Difficulty in recognizing the main features of FTD and psychiatric disorders with memory impairment was observed. Clinicians tended to generalize memory complaints toward a single diagnosis, identifying almost all these patients as AD or leaving them undiagnosed.

    Metabolic bone disease after gastrectomy is one of the complications leading to deterioration in quality of life. The exact mechanism of the metabolic bone disease remains unclear. To clarify the cause of metabolic bone disease after gastrectomy, we evaluated the associations between the method of gastrectomy and the development of metabolic bone disease in a rat model. Rats were assigned to four groups as follows: (1) sham operation (control group); (2) resection of the glandular stomach with Billroth I reconstruction (RGBI group); (3) Roux-en-Y anastomosis preserving the secretory function of the whole stomach (PSRY group); and (4) total gastrectomy with Roux-en-Y reconstruction (TGRY group). In all groups, body weight, serum biochemistry (total protein, albumin, calcium, phosphorus, tartrate-resistant acid phosphatase, and bone alkaline phosphatase), bone density, and bone breaking strength were measured. Body weights and serum calcium levels were significantly lower in the three operation groups compared with the control group. Bone density was significantly lower in the PSRY and TGRY groups compared with the control group. Bone breaking strength was significantly lower in the three operation groups compared with the control group. Surgical methods led to metabolic bone disease. However, exclusion of the duodenum from food passage had major influence to reduction in bone density and breaking strength. A stomach-preserving procedure and physiological reconstruction which enable food passage through duodenum and proximal jejunum contribute to mitigation of metabolic bone disease.

  18. Several issues regarding evaluation of renal injury and renal insufficiency in patients with liver disease

    Directory of Open Access Journals (Sweden)

    HAO Kunyan

    2016-07-01

    Full Text Available In patients with liver disease such as viral hepatitis and liver cirrhosis, renal injury and renal insufficiency can be generally classified as acute kidney injury (AKI, chronic kidney disease, and acute-on-chronic nephropathy. AKI can be classified as stage 1 (risk stage, stage 2 (injury stage, and stage 3 (failure stage. Traditionally hepatorenal syndrome is classified as types Ⅰ and Ⅱ, and in recent years, type Ⅲ hepatorenal syndrome with organic renal injury has been proposed. Hepatorenal disorder(HRD is used to describe any renal disease which occurs in patients with liver cirrhosis. At present, sensitive and accurate biochemical parameters used to evaluate renal function in patients with liver disease in clinical practice include estimated glomerular filtration rate, increase in serum creatinine within unit time, and serum cystatin C level, and urinary microalbumin level also plays an important role in the early diagnosis of nephropathy. Causes of liver disease, severity, complications including infection, nutritional status, therapeutic drugs, and underlying nephropathy may be associated with renal injury and renal insufficiency in patients with liver disease and should be differentiated.

  19. Evaluation and Management of the Patient With Suspected Inflammatory Spine Disease.

    2017-04-01

    Axial spondyloarthritis (AxSpA) is a chronic inflammatory rheumatic disease characterized by inflammatory back pain (IBP) that manifests in childhood, late adolescence, or early adulthood. Ankylosing spondylitis (AS) and nonradiographic AxSpA represent 2 ends of the AxSpA spectrum. Diagnosis can be challenging because patients develop IBP that may not be associated with radiographic changes in the sacroiliac joints. Patients early in the course of disease are estimated to have at least the same level of disease activity and pain as patients with established disease; thus, they could benefit substantially from earlier diagnosis. Although the recent use of magnetic resonance imaging and its inclusion in diagnostic criteria has enhanced the identification of early AxSpA, improvement in early diagnosis has not been consistently reported across all studies. Limited knowledge of the continuum of AxSpA disease manifestations and lack of recognition of IBP in primary practice may contribute to this. Implementing a referral strategy that identifies patients with IBP for additional testing and assessment may lead to better recognition of early signs and symptoms of AxSpA, thereby offering the potential for improved patient outcomes. This review presents an overview of the epidemiology, clinical characteristics, and burdens of AxSpA, followed by a case presentation outlining approaches to the evaluation and management of a patient with suspected inflammatory spine disease.

    The objectives of this paper are to describe the planned implementation and evaluation of the Building on Existing Tools to Improve Chronic Disease Prevention and Screening in Primary Care (BETTER 2) program which originated from the BETTER trial. The pragmatic trial, informed by the Chronic Care Model, demonstrated the effectiveness of an approach to Chronic Disease Prevention and Screening (CDPS) involving the use of a new role, the prevention practitioner. The desired goals of the program are improved clinical outcomes, reduction in the burden of chronic disease, and improved sustainability of the health-care system through improved CDPS in primary care. The BETTER 2 program aims to expand the implementation of the intervention used in the original BETTER trial into communities across Canada (Alberta, Ontario, Newfoundland and Labrador, the Northwest Territories and Nova Scotia). This proactive approach provides at-risk patients with an intervention from the prevention practitioner, a health-care professional. Using the BETTER toolkit, the prevention practitioner determines which CDPS actions the patient is eligible to receive, and through shared decision-making and motivational interviewing, develops a unique and individualized 'prevention prescription' with the patient. This intervention is 1) personalized; 2) addressing multiple conditions; 3) integrated through linkages to local, regional, or national resources; and 4) longitudinal by assessing patients over time. The BETTER 2 program brings together primary care providers, policy/decision makers and researchers to work towards improving CDPS in primary care. The target patient population is adults aged 40-65. The reach, effectiveness, adoption, implementation, maintain (RE-AIM) framework will inform the evaluation of the program through qualitative and quantitative methods. A composite index will be used to quantitatively assess the effectiveness of the prevention practitioner intervention. The CDPS actions

    Full Text Available The Special Programme for Research and Training in Tropical Diseases (TDR is an independent global programme of scientific collaboration cosponsored by the United Nations Children's Fund, the United Nations Development Program, the World Bank, and the World Health Organization. TDR's strategy is based on stewardship for research on infectious diseases of poverty, empowerment of endemic countries, research on neglected priority needs, and the promotion of scientific collaboration influencing global efforts to combat major tropical diseases. In 2001, in view of the achievements obtained in the reduction of transmission of Chagas disease through the Southern Cone Initiative and the improvement in Chagas disease control activities in some countries of the Andean and the Central American Initiatives, TDR transferred the Chagas Disease Implementation Research Programme (CIRP to the Communicable Diseases Unit of the Pan American Health Organization (CD/PAHO. This paper presents a scientometric evaluation of the 73 projects from 18 Latin American and European countries that were granted by CIRP/PAHO/TDR between 1997 and 2007. We analyzed all final reports of the funded projects and scientific publications, technical reports, and human resource training activities derived from them. Results about the number of projects funded, countries and institutions involved, gender analysis, number of published papers in indexed scientific journals, main topics funded, patents inscribed, and triatomine species studied are presented and discussed. The results indicate that CIRP/PAHO/TDR initiative has contributed significantly, over the 1997-2007 period, to Chagas disease knowledge as well as to the individual and institutional-building capacity.

    Human African trypanosomiasis (HAT) is a disease caused by infection with the parasite Trypanosoma brucei gambiense or T. b. rhodesiense. It is transmitted to humans via the tsetse fly. Approximately 70 million people worldwide were at risk of infection in 1995, and approximately 20,000 people across Africa are infected with HAT. The objective of this review was to identify existing economic evaluations in order to summarise cost-effective interventions to reduce, control, or eliminate the burden of HAT. The studies included in the review were compared and critically appraised in order to determine if there were existing standardised methods that could be used for economic evaluation of HAT interventions or if innovative methodological approaches are warranted. A search strategy was developed using keywords and was implemented in January 2014 in several databases. The search returned a total of 2,283 articles. After two levels of screening, a total of seven economic evaluations were included and underwent critical appraisal using the Scottish Intercollegiate Guidelines Network (SIGN) Methodology Checklist 6: Economic Evaluations. Results from the existing studies focused on the cost-effectiveness of interventions for the control and reduction of disease transmission. Modelling was a common method to forecast long-term results, and publications focused on interventions by category, such as case detection, diagnostics, drug treatments, and vector control. Most interventions were considered cost-effective based on the thresholds described; however, the current treatment, nifurtomix-eflornithine combination therapy (NECT), has not been evaluated for cost-effectiveness, and considerations for cost-effective strategies for elimination have yet to be completed. Overall, the current evidence highlights the main components that play a role in control; however, economic evaluations of HAT elimination strategies are needed to assist national decision makers, stakeholders, and

    Receiver operating characteristics (ROC) analysis was performed to evaluate the clinical efficacy of transrectal sonography (US) and computed tomography (CT) for prostatic diseases. One hundred US and CT images of prostatic diseases collected from 10 medical institutions, including 33 cases of prostatic cancer, 29 of benign prostatic hypertrophy, 7 of prostatitis, 2 of prostatic stone and 29 of normal finding, were read by 21 urologists. As the results, US was found to be more useful than CT for both the detection of prostatic diseases and the differentiation between prostatic cancer and benign prostatic hypertrophy. The sensitivity of US for the diagnosis of prostatic cancer was 64.2 % on average of all the urologists. However, the sensitivity was 80.0 % on average of 5 urologists who have read more than 3,000 US images and 59.5 % on average of 16 doctors who have read within 3,000 US images.

    Cortisone is derived from the peripheral metabolism of cortisol and lacks biological activity. The rapid interconversion between cortisol and cortisone has been well established. The altered equilibrium between these steroids may regulate glucocorticoid activity in various tissues. We evaluated the serum levels of cortisol and cortisone, and the cortisone/cortisol ratio in ten children with adrenal diseases using reversed-phase high performance liquid chromatography. Children with hypoadrenalism exhibited a greater decrease in cortisol as compared with cortisone. Cortisone levels were higher than cortisol levels, and the cortisone/ cortisol ratio exceeded 1.0. Children with adrenal cancer exhibited normal or high values of cortisol, whereas cortisone levels were decreased and the cortisone/cortisol ratio was decreased to nearly zero. The ratio returned to normal after the excision of adrenal tumors. The simultaneous evaluation of cortisol, cortisone, and cortisone/cortisol ratio provides a clinical clue of adrenal diseases.

    A substantial amount of data suggested that exposure to secondhand smoke (SHS) could cause cardiovascular diseases and acute coronary events in nonsmoking adults. In order to protect the public from SHS, more and more countries and regions across the world have enacted and implemented smoke-free legislations. Developed countries, such as USA, Canada, the Great Britain, Ireland, Italy and Spain, have carried out many studies to analyze the effects of smoke-free legislations on the hospital admission, incidence and mortality of cardiovascular diseases with the purpose of confirming the health benefits of the smoking ban and promoting the conduct of the ban. We searched PubMed, EMBASE, Web of Science, Cochrane Library,China National Knowledge Infrastructure(CNKI),WANFANG databaseto summarize the study designs, evaluating indicators, statistical methods and results of these studies to provide reference for evaluating smoke-free legislations in inland cities in China.

    To provide an in-depth analysis of outcome measures used in the evaluation of chronic disease self-management programs consistent with the Stanford curricula. Based on a systematic review on self-management programs, effect sizes derived from reported outcome measures are categorized according to the quality of life appraisal model developed by Schwartz and Rapkin which classifies outcomes from performance-based measures (e.g., clinical outcomes) to evaluation-based measures (e.g., emotional well-being). The majority of outcomes assessed in self-management trials are based on evaluation-based methods. Overall, effects on knowledge--the only performance-based measure observed in selected trials--are generally medium to large. In contrast, substantially more inconsistent results are found for both perception- and evaluation-based measures that mostly range between nil and small positive effects. Effectiveness of self-management interventions and resulting recommendations for health policy makers are most frequently derived from highly variable evaluation-based measures, that is, types of outcomes that potentially carry a substantial amount of measurement error and/or bias such as response shift. Therefore, decisions regarding the value and efficacy of chronic disease self-management programs need to be interpreted with care. More research, especially qualitative studies, is needed to unravel cognitive processes and the role of response shift bias in the measurement of change.

    Full Text Available Introduction: One of the most common syndromes in Parkinson's disease (PD is rigidity. Currently, an index is used to evaluate the level of PD by the clinical measurement of rigidity in the upper extremity. The index uses a subjective method called Unified Parkinson's Disease Rating System (UPDRS. The subjective nature of this method makes the influence of physician in the measurement of rigidity possible. Hence, the development of a new standard method based on objective indices is needed. Materials and Methods: In this research, a new device was fabricated and used to measure the viscous and elastic indices and the range of motion during passive movement of elbow joint. The relation between each index and the level of illness was analyzed. The parameters were measured on 41 patients and 11 controls. The indices were extracted using Matlab-R14 software and the statistical analysis was performed using Spss-13. Results: Although there were significant differences in both the viscous and elastic indices between the pair groups and also among the UPDRS groups, but better correlations of the viscous ones and UPDRS were found.  The range of motion by itself has no good correlation with the level of the disease. Discussion and Conclusion: Based on the obtained results, it can be inferred that using viscous indices of rigidity may have an advantage over the elastic ones for the evaluation of Parkinson’s disease. Upon conducting more trials and also considering the sub indices in different parts of the range of motion, the method used here may become a standard objective method for the evaluation of Parkinson's disease.

    Spontaneous Spinal Cerebrospinal Fluid Leaks (SSCFL) is a disease based on tears on the dura mater. Due to widespread symptoms and low frequency of the disease, diagnosis is problematic. Diagnostic lumbar puncture is commonly used for diagnosing SSCFL, though it is invasive and may cause pain, inflammation or new leakages. T2-weighted MR imaging is also used for diagnosis; however, the literature on T2-weighted MRI states that findings for diagnosis of SSCFL could be erroneous when differentiating the diseased and control. One another technique for diagnosis is CT-myelography, but this has been suggested to be less successful than T2-weighted MRI and it needs an initial lumbar puncture. This study aimed to develop an objective, computerized numerical analysis method using noninvasive routine Magnetic Resonance Images that can be used in the evaluation and diagnosis of SSCFL disease. Brain boundaries were automatically detected using methods of mathematical morphology, and a distance transform was employed. According to normalized distances, average densities of certain sites were proportioned and a numerical criterion related to cerebrospinal fluid distribution was calculated. The developed method was able to differentiate between 14 patients and 14 control subjects significantly with p = 0.0088 and d = 0.958. Also, the pre and post-treatment MRI of four patients was obtained and analyzed. The results were differentiated statistically (p = 0.0320, d = 0.853). An original, noninvasive and objective diagnostic test based on computerized image processing has been developed for evaluation of SSCFL. To our knowledge, this is the first computerized image processing method for evaluation of the disease. Discrimination between patients and controls shows the validity of the method. Also, post-treatment changes observed in four patients support this verdict.

    The neuropsychiatric symptoms and behavioral disorders affecting Parkinson's disease (PD) patients are common and disabling. A PD-specific interview-based 12-item scale, the Scale for Evaluation of Neuropsychiatric Disorders in Parkinson's Disease (SEND-PD), has been developed to assess the severity of neuropsychiatric manifestations. The present study is aimed at testing some basic psychometric attributes of this scale. A total of 633 consecutive patients and their caregivers were included in this cross-sectional, multicenter, observational study. In addition to the tested scale, the following assessments were applied: Hoehn and Yahr staging, Scales for Outcomes in Parkinson's Disease Motor and Psychiatric complications, MiniMental State Examination, Clinical Impression of Severity Index, and the Zarit Caregiver Burden Inventory. Patients in all stages of disease were included and 18.38 % were demented. The SEND-PD was responded by patients (86.16 %), caregivers (13.15 %), or both (0.69 %). Three factors (accounting for 66.63 % of the variance) were identified and considered as subscales: Psychotic symptoms, Mood/Apathy, and Impulse control disorders. The subscales showed satisfactory scaling assumptions (multitrait-item success rate 100 %) and internal consistency (alpha indices >0.70). The convergent validity with other measures of psychiatric symptoms and the discriminant validity to distinguish between categories of patients' age, duration and severity of disease, and dopaminergic treatment were satisfactory. The precision of the scale dimensions was acceptable. The SEND-PD performed as an acceptable, consistent, valid, and precise scale for evaluation of neuropsychiatric symptoms in Parkinson's disease.

    Computed tomography (CT) is an effective non-invasive method of evaluating the lumbar spine in cases of suspected disc disease. In over a 3-year period in a high volume neuroradiologic practice we have observed a number of pitfalls in the diagnosis of herniated nucleus pulposus which may lead to erroneous conclusions and therefore, decrease the overall accuracy of the examination. These pitfalls, and their implications are presented and discussed.

    Chagas' disease is caused by the protozoan parasite Trypanosoma cruzi and is one of the most important endemic problems in Latin America. Lately, it has also become a health concern in the United States and Europe. Currently, a diagnosis of Chagas' disease and the screening of blood supplies for antiparasite antibodies are achieved by conventional serological tests that show substantial variation in the reproducibility and reliability of their results. In addition, the specificity of these assays is curtailed by antigenic cross-reactivity with sera from patients affected by other endemic diseases, such as leishmaniasis. Here we used a highly sensitive chemiluminescent enzyme-linked immunosorbent assay (CL-ELISA) to evaluate a recombinant protein core of a mucin-like molecule (termed trypomastigote small surface antigen [TSSA]) for the detection of specific serum antibodies in a broad panel of human sera. The same samples were evaluated by CL-ELISA using as the antigen either a mixture of native T. cruzi trypomastigote mucins or an epimastigote extract and, for further comparison, by conventional serologic tests, such as an indirect hemagglutination assay and indirect immunofluorescence assay. TSSA showed ∼87% sensitivity among the seropositive Chagasic panel, a value which was increased up to >98% when only parasitologically positive samples were considered. More importantly, TSSA showed a significant increase in specificity (97.4%) compared to those of currently used assays, which averaged 80 to 90%. Overall, our data demonstrate that recombinant TSSA may be a useful antigen for the immunodiagnosis of Chagas' disease. PMID:21880857

    This investigation evaluated the knowledge of dental caries and periodontal disease among removable partial denture (RPD) wearers. A total of 127 partially dentate patients participated in this observational study. A structured questionnaire, which included eight questions referring to knowledge about aetiology and prevention of dental caries and periodontal disease, was developed in the local language (Portuguese) and used to collect the data of all the partial denture wearers. A descriptive analysis of data was performed by means of drafting tables. The results demonstrated that 68.5% of patients interviewed had previously received information about oral health care. With regard to bacterial plaque, it was observed that only 34.6% reported having knowledge of this. Whereas, in relation to caries, 76.4% of the interviewees replied that they knew the meaning of this. Nevertheless, 28.3% referred to caries as a whole in the teeth, 16.5% as bad teeth and 9.4% bacteria/creatures on the teeth. Only 17.3% of the partially edentulous patients evaluated were shown to know what disease of the gingiva was. By means of the methodology applied, it could be concluded that the patients who wore RPDs presented deficient knowledge with regard to the prevention, aetiology and development of dental caries and periodontal disease. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

    Tc-99m MDP bone scans were used to evaluate the heel pain (talalgia) in 38 patients with Reiter's disease, and compared with clinical examination and radiologic findings. In our work, 58% (22/38) patients presented talalgia with a total of 35 lesions. Only two lesions of clinical talalgia were missed by the bone scan. The diagnostic sensitivity was as high as 94% (33/35). However, the diagnostic sensitivity of radiography was only 69% (11/16) when the disease duration was more than one year; furthermore, it declined to 33% (4/12) when the disease duration was less than one year. Based on the bone scans, the correlation between positive scintigraphic findings and clinical talalgia was extremely good. Clinical talalgia occurred in all the 33 lesions demonstrated by bone scan. However, three lesions demonstrated by radiography were not consistent with clinical talalgia and not visualized by radioscintigraphy. Our data show that the radionuclide scan is a more sensitive indicator and has better correlation with clinical talalgia than radiography. We consider that bone scintigraphy is superior to radiography in the evaluation of heel pain in Reiter's disease.

    In about 20-25% of patients with congenital long QT syndrome (LQTS) a causative pathogenic mutation is not found. The aim of this study was to explore the prevalence of alternative cardiac diagnoses among patients exhibiting prolongation of QT interval with negative genetic testing for LQTS genes. We conducted a retrospective analysis of 239 consecutive patients who were evaluated in the inherited arrhythmia clinic at the Toronto General Hospital between July 2013 and December 2015 for possible LQTS. A detailed review of the patients' charts, electrocardiograms, and imaging was carried out. The analysis included 56 gene-negative patients and 61 gene-positive patients. Of the gene-negative group, 25% had structural heart disease compared to only 1.6% of gene-positive patients (P < 0.001). Structural heart disease was more likely if only one abnormal QTc parameter was found in the course of the evaluation (35.2% vs 9.1%, P = 0.01). The most common structural cardiac pathology was bileaflet mitral valve prolapse (8.9%). No gene-positive patient had episodes of nonsustained ventricular tachycardia, compared to seven of the gene-negative patients (0% vs 12.5%, P = 0.005). Structural pathology was detected in a quarter of gene-negative patients evaluated for possible LQTS. Hence, cardiac imaging and Holter monitoring should be strongly encouraged to rule out structural heart disease in this population. © 2017 Wiley Periodicals, Inc.

    To systematically review the evidence on the accuracy of MRI for grading disease activity in Crohn's disease (CD). The MEDLINE, EMBASE, CINAHL and Cochrane databases were searched for studies on the accuracy of MRI in grading CD compared to a predefined reference standard. Two independent observers scored all relevant data. Three disease stages were defined: remission, mild and frank disease. The accuracy rates of MRI per disease stage were calculated by means of a random-effects model. Seven studies were included from a search resulting in 253 articles. In total 140 patients (16 patients in remission, 29 with mild disease and 95 with frank disease) were used for data analysis. MRI correctly graded 91% (95% CI: 84-96%) of patients with frank disease, 62% (95% CI: 44-79) of patients with mild disease and 62% (95% CI: 38-84) of patients in remission. MRI more often overstaged than understaged disease activity; MRI overstaged disease activity in 38% of patients in remission, mostly as mild disease. Overstaging of mild disease was observed in 21%, understaging in 17%. MRI correctly grades disease activity in a large proportion of patients with frank disease. For patients in remission or with mild disease, MRI correctly stages disease activity in many patients (62%). (orig.)

    Full Text Available Vineyard experiments were conducted over five years in the Bordeaux area to evaluate the effectiveness of trunk injections in controlling Eutypa dieback (4 trials and esca (1 trial. Single treatments were applied in winter 2001 or 2002 using the tree injector StemJect®. Three compounds were tested: two triazole-derived fungicides, propiconazole and difenoconazole, and one elicitor, 2-hydroxybenzoïc acid. Symptomatic vines of two susceptible cultivars, Cabernet Sauvignon and Cabernet Franc, had first been identified in summer in the year before the treatments were started. A disease scale was used to rate the severity of the foliar symptoms. After treatment, disease development was recorded on the same vines in the following years, from 2002 to 2005. Analyses were based on the evolution of foliar symptoms and on the development of wood symptoms (% area of dead wood. This novel procedure made it possible to determine the sanitary status of each vine in terms of three classes of disease severity: remission of symptoms, stability or worsening. No treatment had a significantly durable effect on disease expression irrespective of the site, the compound or the disease studied. Some phytotoxic effects with the triazole fungicides were noticed. Prospects for trunk injections as a means to solve these insidious problems in viticulture are discussed.

    Patients with inflammatory bowel diseases often undergo surgical procedures for medically refractory disease or colitis associated dysplasia. Endoscopic evaluation of the surgically altered bowel is often needed to assess for disease recurrence, its severity, and for therapy. It is important to obtain and review the operative report and abdominal imaging before performing the endoscopy. Diagnostic and therapeutic endoscopy can be safely performed in most patients with inflammatory bowel disease with altered bowel anatomy under conscious sedation without fluoroscopy. Carefully planned stricture therapy with balloon dilation or needle knife stricturotomy can be performed for simple, short, and fibrotic strictures. A multidisciplinary approach involving a team of endoscopist, endoscopy nurse, colorectal surgeon, gastrointestinal pathologist, and gastrointestinal radiologist is important for a safe and effective endoscopy. We attempt to review the aspects that need consideration before the endoscopy, the technique of endoscopy, and briefly the therapies that can be performed during endoscopy of the bowel through an ileostomy, a colostomy, in the diverted large bowel or ileal pouch, and small bowel after stricturoplasty and bowel bypass surgery in patients with inflammatory bowel diseases.

    Parkinson is a common and disabling disease that affects patient's and career's quality of life. Unfortunately, medications, such as dopaminergic and sedative-hypnotic drugs, as an effective treatment have unwilling side effects. Recently, Transcranial Direct Current Stimulation (tDCS) in conjunction with medication becomes popular as a complementary safe treatment and several studies have proved its effectiveness on controlling motor and specially non-motor aspects of Parkinson's disease. In this randomized double-blind parallel study, 23 patients with Parkinson's disease divided into two groups of real tDCS plus occupational therapy and sham tDCS plus occupational therapy and the effects of therapeutic sessions (eight sessions tDCS with 0.06 mA/cm(2) current, 20 min on dorsolateral prefrontal cortex) were evaluated on fatigue and daytime sleepiness just after therapeutic course and in 3-month follow-up. tDCS had a significant effect on fatigue and no effect on daytime sleepiness reduction in patients with Parkinson's disease. tDCS is an effective and safe complementary treatment on fatigue reduction in Parkinson's disease.

    To determine the Ontario-specific risk of local and travel-related Zika virus transmission in the context of a public health emergency of international concern, Public Health Ontario (PHO) completed a rapid risk assessment (RRA) on January 29, 2016, using a newly developed RRA guidance tool. The RRA concluded that risk of local mosquito-borne transmission was low, with a high risk of imported cases through travel. The RRA was updated 3 times based on predetermined triggers. An independent evaluation assessed both the application of the RRA guidance tool (process evaluation) and the usefulness of the RRA (outcome evaluation). We conducted face-to-face, semi-structured interviews with 7 individuals who participated in the creation or review of the Zika virus RRA and 4 end-users at PHO and the Ministry of Health and Long-Term Care. An inductive thematic analysis of responses was undertaken, whereby themes were directly informed by the data. The process evaluation determined that most steps outlined in the RRA guidance tool were adhered to, including forming a cross-functional writing team, clarifying the scope and describing context, completing the RRA summary report, and updating the RRA based on predefined triggers. The outcome evaluation found that end-users judged the Zika virus RRA as evidence-informed, useful, consistent, and timely. The evaluation established that the locally tailored guidance tool, adapted from national and international approaches to RRAs, facilitated a systematic, evidence-informed, and timely formal RRA process at PHO for the Zika virus RRA, which met the needs of end-users. Based on the evaluation, PHO will modify future RRAs by incorporating some flexibility into the literature review process to support timeliness of the RRA, explicitly describing the limitations of studies used to inform the RRA, and refining risk algorithms to better suit emerging infectious disease threats. It is anticipated that these refinements will improve upon the

    Full Text Available Digital disease detection tools are technologically sophisticated, but dependent on digital information, which for many areas suffering from high disease burdens is simply not an option. In areas where news is often reported in local media with no digital counterpart, integration of local news information with digital surveillance systems, such as HealthMap (Boston Children's Hospital, is critical. Little research has been published in regards to the specific contribution of local health-related articles to digital surveillance systems. In response, the USAID PREDICT project implemented a local media surveillance (LMS pilot study in partner countries to monitor disease events reported in print media. This research assessed the potential of LMS to enhance digital surveillance reach in five low- and middle-income countries. Over 16 weeks, select surveillance system attributes of LMS, such as simplicity, flexibility, acceptability, timeliness, and stability were evaluated to identify strengths and weaknesses in the surveillance method. Findings revealed that LMS filled gaps in digital surveillance network coverage by contributing valuable localized information on disease events to the global HealthMap database. A total of 87 health events were reported through the LMS pilot in the 16-week monitoring period, including 71 unique reports not found by the HealthMap digital detection tool. Furthermore, HealthMap identified an additional 236 health events outside of LMS. It was also observed that belief in the importance of the project and proper source selection from the participants was crucial to the success of this method. The timely identification of disease outbreaks near points of emergence and the recognition of risk factors associated with disease occurrence continue to be important components of any comprehensive surveillance system for monitoring disease activity across populations.

This study was completed by the research and promotion base for traditional Chinese medicine(TCM) standard. The methods of applicability evaluation and application evaluation were used in the study. The questionnaires were filled out to evaluate applicability of the guideline, including doctor's familiarity with the guideline,the quality of the guideline, applicable conditions and clinical applications. The prospective case study analysis method was used to evaluate application of the guideline, including evaluation of clinical application compliance and application results(such as clinical effects, safety and economy). There were two parts in the guideline, which were TCM guideline and Western medicine guideline. The results of applicability evaluation showed that there were no obvious differences between TCM guideline and Western medicine guideline in doctor's familiarity with guideline(85.43%, 84.57%) and the use of the guideline(52.10%, 54.47%); the guidelines with good quality, and higher scores in the scope of application and the use of the term rationality(91.94%, 93.35%); the rationality scores of relevant contents in syndrome differentiation and treatment were more than 75%; the applicable conditions were better, and the safety score was the the highest. The comprehensive applicability evaluation showed that the proportion of the application of TCM guideline and Western medicine guideline were 77.73%, 75.46%, respectively. The results of application evaluation showed that there was high degree coincidence between the guideline with its clinical application; except for "other treatment" and "recuperation and prevention" in TCM, other items got high scores which were more than 90%; in the evaluation of application effects, safety of the guideline

    Full Text Available Background. Changes in proprioception may contribute to postural instability in individuals with neurological disorders. Objectives. Evaluate proprioception in the lower limbs of patients with Parkinson’s disease (PD and the association between proprioception and cognitive ability, motor symptoms, postural instability, and disease severity. Methods. This is a cross-sectional, controlled study that evaluated proprioception in PD patients and healthy age- and sex-matched individuals. Kinetic postural proprioception of the knee was evaluated using an isokinetic dynamometer (Biodex® Multi-Joint System 4 Pro. Participants were evaluated using the Montreal Cognitive Assessment (MoCA, the Hoehn and Yahr rating scale and postural instability (pull test and stabilometric analysis, and motor function (UPDRS-III tests. Results. A total of 40 individuals were enrolled in the study: 20 PD patients and 20 healthy controls (CG. The PD patients had higher angular errors on the proprioceptive ratings than the CG participants (p=0.002. Oscillations of the center of pressure (p=0.002 were higher in individuals with PD than in the controls. Proprioceptive errors in the PD patients were associated with the presence of tremors as the dominant symptom and more impaired motor performance. Conclusion. These findings show that individuals with PD have proprioceptive deficits, which are related to decreased cognitive ability and impaired motor symptoms.

    To evaluate the efficacy and safety of evaluation,treatment and follow-up of Kawasaki coronary artery disease based on the clinical severity classification. This study evaluated 52 patients admitted to the Children's Hospital of Fudan University between July 2005 and December 2013 who were diagnosed with Kawasaki Disease with coronary artery disease.Inclusion criteria were a disease course of more than two months, initial echocardiography showing severity of grade IV and above, and confirmation of disease severity by angiography. Of those studies, 44 were male and eight were female, aged 6 to 142 (average 41) months. Treatment was planned according to protocols in "Suggestions for Management of Kawasaki Coronary Artery Disease" with follow-up. Those patients with grade IV and above confirmed by angiogram were given oral low-dose asprin and warfarin, and those with grade Vb were given coronary artery bypass grafting (CABG) after comprehensive evaluation. Analysis was carried out for diagnosis, treatment, complications, and results of follow-up. (1) Satisfied images were shown by the angiography of all 52 cases. Forty five patients (86%) had giant aneurysm or multiple aneurysms, with thrombosis found in 10 of 45 patients (22%). Coronary artery lesions occurred in 138 coronary branches, and more common in left anterior descending branch (47 branches, with incidence 34%) and right coronary artery (48 branches, with incidence 35%). There were no complications during or after angiography. (2) After angiography, 49 patients remained at grade IV or above, and three improved to grade III. Ultimately, clinical severities of coronary artery disease included three patients at grade III, 31 patients at grade IV, nine patients at grade Va, and nine patients at grade Vb. (3) Thirty-eight patients were properly using aspirin and warfarin, and two patients with severely elevated international normalized ratio (INR) levels presented with knee joint and gastric hemorrhage, both of

    To evaluate conjunctival impression cytology and HLADR expression changes after wearing scleral contact lenses (ScCLs) for moderate to severe dry eye disease (DED). Prospective interventional case series. Forty-one eyes from 25 patients with moderate to severe DED were evaluated for Esclera ScCL treatment. Best-corrected visual acuity (BCVA) and slit-lamp findings were assessed. Impression cytology specimens were obtained from DED patients at the baseline and after wearing ScCLs for 12 months. The impression cytology specimens were analyzed using morphological results score, and HLA-DR positive cells were detected and quantified. The values were compared to assess the IC changes after wearing ScCLs. Forty-one eyes from 25 patients were fitted with ScCLs to manage DED. The underlying diseases were Stevens-Johnson syndrome (22 eyes), Sjogren's syndrome (11 eyes), graft-versus-host disease (2 eyes), dry eye after keratomileusis (2 eyes) and undifferentiated ocular surface disease (4 eyes). The HE-PAS impression cytology score did not differ significantly before and after wearing ScCLs for 12 months in DED patients (p>0.05). The percentage of eyes expressing the HLA-DR antigen in the temporal conjunctiva after wearing ScCL for 12 months significantly increased in patients with Sjogren's syndrome (11.11% to 66.66%; p=0.0498). In groups with Stevens Johnson syndrome and other ocular surface disorders, we did not observe statistically significant differences (p>0.05). The ScCLs did not change the parameters used to evaluate inflammatory processes, which were measured using conjunctival impression cytology and HLA-DR expression, except in Sjogren syndrome, in which there was an unexpected increase in HLA expression.

    The factors contributing to superficial vein thrombosis (SVT) in patients with varicose vein disease are unclear. Differences in vein wall apoptotic activity could be associated with the pathogenesis of SVT. The aim of the study is to address the role of the programmed cell death in the vein wall by comparing varicose veins with history of SVT to uncomplicated varicose veins. Vein segments from the proximal part of the great saphenous vein (GSV), the distal part of the vein and from a varicose tributary, from 16 patients with varicose vein disease and one episode of SVT, were evaluated for the immunohistochemical expression of pro-apoptotic (Bax, p53, Caspase 3, BCL-6, BCL-xs), anti-apoptotic (BCL-xl and BCL-2) and proliferation (Ki-67) markers. The results of this study were compared to the results from the evaluation of 19 patients suffering from uncomplicated varicose vein disease and 10 healthy GSVs as controls. Overall, there was increased apoptosis in the distal part of GSV compared to the proximal part documented by increased expression of Bax (p SVT showed significant differences among the three different anatomic locations. In the proximal GSV, only BCL-xs was higher in patients with SVT (p = 0.029). In the tributaries, Bax, BCL-xl and Ki-67 were higher in patients with SVT (p SVT shows increased pro-apoptotic activity compared to uncomplicated disease and normal veins. Whether increased vein wall cell apoptosis is a causative factor for SVT in varicose veins disease or a repairing mechanism of the thrombosis itself needs further research.

    Unmedicated Parkinson's disease patients tend to be risk-averse while dopaminergic treatment causes a tendency to take risks. While dopamine agonists may result in clinically apparent impulse control disorders, treatment with levodopa also causes shift in behaviour associated with an enhanced response to rewards. Two important determinants in decision-making are how subjects perceive the magnitude and probability of outcomes. Our objective was to determine if patients with Parkinson's disease on or off levodopa showed differences in their perception of value when making decisions under risk. The Vancouver Gambling task presents subjects with a choice between one prospect with larger outcome and a second with higher probability. Eighteen age-matched controls and eighteen patients with Parkinson's disease before and after levodopa were tested. In the Gain Phase subjects chose between one prospect with higher probability and another with larger reward to maximize their gains. In the Loss Phase, subjects played to minimize their losses. Patients with Parkinson's disease, on or off levodopa, were similar to controls when evaluating gains. However, in the Loss Phase before levodopa, they were more likely to avoid the prospect with lower probability but larger loss, as indicated by the steeper slope of their group psychometric function (t(24) = 2.21, p = 0.04). Modelling with prospect theory suggested that this was attributable to a 28% overestimation of the magnitude of loss, rather than an altered perception of its probability. While pre-medicated patients with Parkinson's disease show risk-aversion for large losses, patients on levodopa have normal perception of magnitude and probability for both loss and gain. The finding of accurate and normally biased decisions under risk in medicated patients with PD is important because it indicates that, if there is indeed anomalous risk-seeking behaviour in such a cohort, it may derive from abnormalities in components of

    Full Text Available To evaluate the contribution of breastfeeding to Rotavirus (RV-induced antigenemia and/or RNAemia and disease severity in Indian children (<2 yrs age.Paired stool and serum samples were collected from (a hospitalized infants with diarrhea (n = 145 and (b healthy control infants without diarrhea (n = 28. Stool RV-antigen was screened in both groups by commercial rapid-test and enzyme immunoassay. The disease severity was scored and real-time-PCR was used for viral-load estimation. Serum was evaluated for RV-antigenemia by EIA and RV-RNAemia by RT-PCR. Data was stratified by age-group and breastfeeding status and compared.Presence of RV-antigenemia and RV-RNAemia was positively related with presence of RV in stool. Disease severity and stool viral-load was significantly associated with RV-antigenemia [(r = 0.74; CI:0.66 to 0.84; P<0.0001,R2 = 0.59 and (r = -0.55; CI:-0.68 to -0.39; P<0.0001,R2 = 0.31 respectively], but not with RV-RNAemia. There was significant reduction in RV-antigenemiarate in the breast-fed group compared to non-breastfed infants, especially in 0-6 month age group (P<0.001. Non-breastfed infants were at risk for RV-antigenemia with severe disease manifestations in form of high Vesikari scores correlating with high fever, more vomiting episodes and dehydration.RV-antigenemia was common in nonbreastfed children with severe RV-diarrhea and correlated with stool RV-load and disease severity.

    Axial computed tomographic (CT) images were compared with sagittal and coronal reformations and myelograms in 60 patients to evaluate the diagnostic usefulness of multiplanar reconstructions for the recognition of lumbar disk disease. The axial CT scans were most sensitive and specific. The sagittal scans were helpful in evaluating the neural foramina, the size of the disk bulge into the spinal canal, especially at L5-S1, and patients with spondylolisthesis. The coronal images were the least informative, although they contributed to the evaluation of lumbar nerve roots. The myelograms and the sagittal images were equally useful in the detection of herniated disk, but axial scans were superior to either. It was concluded that reformatted sagittal and coronal images are not required if all axial images are normal.

    Chronic kidney disease and its worsening are recurring conditions in chronic heart failure (CHF) which are independently associated with poor patient outcome. The heart and kidney share many pathophysiological mechanisms which can determine dysfunction in each organ. Cardiorenal syndrome is the condition in which these two organs negatively affect each other, therefore an accurate evaluation of renal function in the clinical setting of CHF is essential. This review aims to revise the parameters currently used to evaluate renal dysfunction in CHF with particular reference to the usefulness and the limitations of biomarkers in evaluating glomerular dysfunction and tubular damage. Moreover, it is reported the possible utility of renal arterial resistance index (a parameter associated with abnormalities in renal vascular bed) for a better assesment of kidney disfunction.

    The aim of this paper is to develop a methodological framework to facilitate the application of Multi-Criteria Decision Analysis (MCDA) for a comprehensive economic evaluation of disease management programs (DMPs). We studied previously developed frameworks for the evaluation of DMPs and different methods of MCDA and we used practical field experience in the economic evaluation of DMPs and personal discussions with stakeholders in chronic care. The framework includes different objectives and criteria that are relevant for the evaluation of DMPs, indicators that can be used to measure how DMPs perform on these criteria, and distinguishes between the development and implementation phase of DMPs. The objectives of DMPs are categorised into a) changes in the process of care delivery, b) changes in patient lifestyle and self-management behaviour, c) changes in biomedical, physiological and clinical health outcomes, d) changes in health-related quality of life, and e) changes in final health outcomes. All relevant costs of DMPs are also included in the framework. Based on this framework we conducted a MCDA of a hypothetical DMP versus usual care. We call for a comprehensive economic evaluation of DMPs that is not just based on a single criterion but takes into account multiple relevant criteria simultaneously. The framework we presented here is a step towards standardising such an evaluation.

    Full Text Available Bacground/Aim. Diagnostic protocol for patients with degenerative diseases of the cervical spine demands, in parallel with neuroimaging methods, functional evaluation through neurophysiological methods (somatosensitive and motor evoked potentials and electromyoneurography aiming to evaluate possible subclinical affection of spinal medula resulting in neurological signs of long tract abnormalities. Considering diversities of clinical outcomes for these patients, complex diagnostic evaluation provides a prognosis of the disease progression. Methods. The study included 21 patients (48.24 ± 11.01 years of age with clinical presentation of cervical spondylarthropathy, without neuroradiological signs of myelopathy. For each patient, in addition to conventional neurophysiological tests (somatisensory evoked potentials - SSEP, motor evoked potentials - MEP, electromyoneurography - EMG, nerve conduction studies, we calculated central motor conduction time (CMCTF, as well the same parameter in relation to a different position of the head (maximal anteflexion and retroflexion, so-called dynamic tests. Results. Abnormalities of the peripheral motor neurone by conventional EMNeG was established in 2/3 of the patients, correponding to the findings of root condution time. Prolonged conventional CVMPF were found in 29% of the patients, comparing to 43% CVMPF abnormalities found with the dynamic tests. In addition, the SSEP findings were abnormal in 38% of the patients with degenerative diseases of the cervical spine. Conclusion. An extended neurophysiological protocol of testing corticospinal functions, including dynamic tests of central and periheral motor neurons are relevant for detection of subclinical forms of cervical spondylothic myelopathy, even at early stages. In addition to the conventional neurophysiological tests, we found usefull to include the dynamic motor tests and root conduction time measurement in diagnostic evaluation.

    The infliximab (Remicade; Schering-Plough, Kenilworth, NJ, USA) Risk Management Plan included the development, execution and tracking of an education programme directed towards prescribers of infliximab for patients with paediatric Crohn's disease (the Infliximab Paediatric Crohn's Disease Educational Plan). The programme content consisted of educational materials and communications aimed at educating prescribers on the risks associated with infliximab use. To evaluate the effectiveness of the risk minimization plan. Evaluation focused on two components: documentation of training of sponsors' personnel, and evaluation of awareness among prescribing physicians in European countries. Treating physicians, identified both independently of the sponsor (6 countries) and by the sponsor (24 countries), were surveyed using a structured questionnaire. Training of internal staff on the educational programme was performed and completed by every person designated an appropriate candidate for the programme in all European countries. The independent survey conducted in Germany, France, Italy, Spain, Sweden and the UK indicated that around 90% of the physicians were either paediatric gastroenterologists (57%) or paediatricians (33%). The great majority (96%) of the interviewed physicians were currently treating paediatric Crohn's disease, and most were currently using infliximab in their treatment of the disease. More specifically, 82% of gastroentrologists treating paediatric Crohn's disease were using infliximab; among paediatricians, the proportion was lower (42%). Ninety-six percent of paediatric gastroenterologists or gastroenterologists declared themselves aware of the benefits and risks of using infliximab for the treatment of paediatric Crohn's disease; in comparison, fewer paediatricians (82%) declared themselves aware of these benefits and risks. The majority initially gained awareness through congresses and workshops, and at the time of the survey only 25% declared that

    Type 2 diabetes disease management programmes (DDMPs) are offered by German social health insurance to promote healthcare consistent with evidence-based medical guidelines. The aim of this study was to compare healthcare quality and medical endpoints between diabetes management programme participants and patients receiving usual care designated as controls. All patients with type 2 diabetes (age range: 36-81) in a cross-sectional survey of a cohort study, performed by the Cooperative Health Research in the Region of Augsburg, received a self-administered questionnaire regarding their diabetes care. Physical examination and laboratory tests were also performed. The analysis only included patients with social health insurance and whose participation status in a diabetes disease management program was validated by the primary physician (n = 166). Regression analyses, adjusting for age, sex, education, diabetes duration, baseline waist circumference and clustering regarding primary physician were conducted. Evaluation of healthcare processes showed that those in diabetes disease management programmes (n = 89) reported medical examination of eyes and feet and medical advice regarding diet [odds ratio (OR): 2.39] and physical activity (OR: 2.87) more frequently, received anti-diabetic medications (OR: 3.77) and diabetes education more often (OR: 2.66) than controls. Both groups had satisfactory HbA(1c) control but poor low-density lipoprotein cholesterol control. Blood pressure goals (diabetes disease management programmes (OR: 2.21). German diabetes disease management programmes are associated with improved healthcare processes and blood pressure control. Low-density lipoprotein cholesterol control must be improved for all patients with diabetes. Further research will be required to assess the long-term effects of this diabetes disease management programme. Copyright © 2011 John Wiley & Sons, Ltd.
