Spinal cystic echinococcosis - a systematic analysis and review of the literature : part 2. treatment, follow-up and outcome

Bone involvement in human cystic echinococcosis (CE) is rare, but affects the spine in approximately 50% of cases. Despite significant advances in diagnostic imaging techniques, surgical treatment and introduction of pharmacological therapy, spinal echinococcosis remains associated with a high degree of morbidity, disability and mortality. We systematically reviewed the published literature of the last five decades to update and summarize the currently existing data on treatment, follow-up and outcome of spinal CE

An Atypical Presentation of Cystic Echinococcosis

Cystic echinococcosis (CE) is an infection caused by the Echinococcus granulosus tapeworm. CE generally manifests in the liver, but it may present in any organ. These patients often first present to the emergency department. Mortality over 10 years is significant for those who go undiagnosed. We report the case of a 34-year-old patient who immigrated from Yemen six years earlier. She presented with acute onset dysuria, suprapubic pain, and fever. Imaging revealed a primary multicystic mass on the right renal pole with a secondary lesion in the right hepatic lobe. On further investigation, the patient’s serum was positive for echinococcus antibodies

Primary splenic hydatidosis

Hydatid disease is becoming a public health problem in Nepal. Majority of the patients have hydatidosis of liver and lungs. Primary splenic hydatidosis is rare. The clinical presentation of primary splenic hydatidosis is similar to other cystic splenic pathologies. It presents with slow growing, dull aching left upper quadrant abdominal lump. Ultrasonography and computed tomography scans are helpful in diagnosis. We report a 36 years lady with primary splenic hydatidosis, who successfully underwent open en bloc resection of hydatid cyst along with total splenectomy. Keywords:  primary splenic hydatidosis, splenic hydatid cys

Rupture of a giant cardiac hydatid cyst in the left ventricular free wall: successful surgical management of a rare entity

Hydatid cyst of heart is a rare but potentially fatal site of pathology, especially left ventricular free wall. We managed a successful surgical treatment on a case of a 24 year old man who had a giant cardiac hydatid cyst (71 x 64 mm) that ruptured left ventricular free wall. The cyst was excised gently and all the cystic materials were removed, the cyst cavity was closed with GORE-TEX soft tissue patch. The patient was discharged on the 9th postoperative day without symptoms. This case is different from other cardiac hydatid cysts that have been reported in literature previously; because this patient was young and had advanced phase of the disease that presented to our clinic lately. Additionally, the cyst had limited both ventricular volumes significantly

Giant intra-abdominal hydatid cysts with multivisceral locations

The disseminated intra-peritoneal hydatid disease is a very rare finding. A case of disseminated intra abdominal hydatid disease is presented along with a review of literature and various therapeutic modalitie

The common and uncommon cestodal infestation encountered in routine histopathological practice from a semi-urban population in south India and their public health importance.

Parasites are encountered uncommonly in routine histopathologic practice. Among them, cestodes form a major bulk. Cysticercosis heads the list forming the bulk of cases followed by Hydatidosis and Sparganosis. Microscopic identification of inflammation with surrounding reactions along with other morphological features forms the mainstay of diagnosis of parasitic diseases on histopathology. Identification of the parasites on histopathological examination would reduce the cost-diagnosis ratio avoiding expensive serological investigation

Genetic survey of alveolar and cystic echinococcoses in Romania: first molecular evidence of Echinococcus multilocularis in humans in the country

Cystic echinococcosis (CE) and alveolar echinococcosis (AE) are considered as one of the most important zoonotic diseases in Romania, where they are subject to mandatory reporting. To obtain more knowledge about the genetic diversity of Echinococcus causative agents of these diseases, 11 isolates from humans and ungulate intermediate hosts from the two regions of Romania were genotyped using mitochondrial markers. In clinical samples of fi ve patients from north-eastern Romania (Iasi, Botosani, Vaslui counties), Echinococcus multilocularis was identifi ed as causal agent by cox1 sequence analysis. To the best of our knowledge this fi nding presents the fi rst molecular evidence of E. multilocularis in humans from Romania. Only two cases of AE in patients were previously documented in the country by serological methods. In our four patients the most widespread European variant E5 of E. multilocularis was recorded, whereas in isolate from Vaslui county three nucleotide substitutions were detected as compared to the most related E5 haplotype. One of these mutations (411T/G) matched N1 and N2 haplotypes described previously from North America. In six CE samples retrieved from western Romania (Caras-Severin and Timis counties), two human isolates were diagnosed as Echinococcus canadensis G7, one as E. granulosus s.s. G1 and one as E. granulosus s.s. G3 using atp6 and rrnS sequencing. In ungulates, the cattle isolate was allocated to E. granulosus s.s. G1 and pig isolate to E. canadensis G7. The two G7 fi ndings in humans reinforced the recent view that G7 was underestimated as compared to the E. granulosus s.s. regarding human CE threat that can be further employed for identifying sources of infections and establishing suitable preventive measures

Isolated Renal Hydatidosis Presenting as Renal Mass: A Diagnostic Dilemma

AbstractHydatid disease is a parasitic infestation by larval form of Echinococcus granulosus. Isolated renal involvement is extremely rare. There are no specific signs and symptoms of renal hydatidosis. However it may present as palpable mass, flank pain, hematuria, malaise, fever, and hydatiduria or as a complication of it such as infection, abscess, hemorrhage, necrosis and pelviureteric junction obstruction, renal failure etc. Except hydatiduria, none are pathognomonic for renal hydatidosis. There is no literature on renal hydatidosis presenting as renal mass we report 2 cases of isolated renal hydatidosis, which mimicked a renal mass on imaging study

Bovine Hydatidosis in Eastern Part of Ethiopia

A cross-sectional study was conducted on bovine hydatidosis from November 2010 to March 2011 with the aims of investigating its occurrence, risk factors and economic losses in Dire Dawa municipality abattoir. The study revealed 20.05% occurrence of hydatidosis based on the postmortem examination of1536 cattle. Age related infection was significant as older animals were more infected (P<0.05, x2 = 27.496).Among the lungs, liver, heart, spleen and kidneys examined in each carcass, the cysts were distributed in the lungs and livers only. Out of 1852 cysts, 1340 (72.3%) were found in liver while512 (27.7%) in lungs. Five hundred and twenty (53.94%) of 964 hydatid cysts were small, while268 (27.80%) medium and 176 (18.25%) large. These cysts were further characterized as fertile (80.08.7%), sterile (17.3%) and calcified (2.85%) and 53.7% of fertile cysts were viable. Based on the study, the direct economic loss was estimated to be 23,876 Ethiopian Birrs. Presence of hydatid cysts in edible organs has great public health significance as consumption of undercooked/raw meat is still in practice in many parts of Ethiopia.Keywords: Abattoir, Bovine, Carcass, Cysts, Hydatidosis, Eastern Ethiopia

Infection prevalence of hydatidosis (Echinococcus granulosus, Batsch, 1786) in domestic animals in Ethiopia: A synthesis report of previous surveys

Hydatidosis/echinococcosis (Echinococcus granulosus, Batsch, 1786) is considered to be a serious problem for both public health and the livestock economy in Ethiopia. The present paper reviews and summarizes available data on the disease. Abattoir survey data collected over a period of 15 years (1985-1999) were analyzed to assess the infection prevalence of hydatidosis in domestic animals in three different agroecological zones of Ethiopia. Accordingly, 8036/22,863 (35.15%) cattle, 768/6518 (11.78%) sheep, 36/1753 (4.9%) goats, 70/417 (16.79%) camels and 0/150 (0%) pigs slaughtered in 21 different abattoirs located in various parts of the country were found harbouring hydatid cysts. A statistical discernible significant difference (
