This paper focuses on recent developments in the areas of mode of action and clinical efficacy of mebendazole use since its introduction in 1974. Mebendazole blocks glucose uptake by adult intestinal-dwelling nematodes and cestodes and their tissue-dwelling larvae. The drug's poor absorption does not appear to affect clinical efficacy except in the treatment of systemic helminth infections. Mebendazole has been found to be ovicidal for the eggs of roundworm, hookworm, and whipworm with the disadvantages of cost and long duration of therapy; it is also considered the best drug for the treatment of trichuriasis. Among its nonapproved uses, it shows promise in the treatment of capillariasis and hydatid disease. Further investigation is needed to establish its role in the treatment of taeniasis, Hymenolepsis nana, Strongyloidiasis, Trichinosis, and Dipetalonema perstans. Side effects such as diarrhea, abdominal pain, headache, and dizziness have been reported on rare occasions.

An echinococcal cyst of the heart is a rare cause of acute cardiac tamponade. We report on a 24 year old male from the Kosovo who was brought in an emergency state from a provincial hospital complaining of severe dyspnea, thoracic pain, dizziness, and a short period of unconsciousness. Surgical decompression had to be performed urgently, because the pericardium could not be punctuated due to the position of the hydatid cyst. The differential diagnosis was cardiac tumor or echinococcal cyst. Because of a negative result of a test for anti-echinococcal antibodies (indirect haemagglutination) and no eosinophilia (5%), the diagnosis of hydatid cyst was at first discarded. Later on, the test for anti-echinococcal antibodies became positive and a marked eosinophilia (59%) was manifest. In combination with a typical appearance in the echocardiograph and NMR, the diagnosis of a cardiac hydatid cyst was made. After preoperative treatment with albendazole, the cyst was sterilized with a 20% NaCl solution and the contents evacuated. The therapy with albendazole was continued. When last seen eight months after the first incidence, the patient was well except some degree of dyspnea on exertion. As a differential diagnosis of a cardiac tumor, a hydatid cyst should be taken into account in patients from an area where Echinococcus granulosus is endemic. A negative test on antiechinococcal antibodies and the absence of eosinophilia do not rule out echinococcosis.

The ratio of cardiac involvement of Echinoccocus granulosus is 0.02-2% and although seen rarely, involvement of the interatrial septum has also been reported in the published literature. The present case was a 19-year-old male university student admitted to hospital with complaints of headache and dizziness. Computerized tomography of the cranium revealed a cystic mass located at the frontal region and enucleation of the cyst was performed during surgery. A cystic lesion 5 x 4 cm in size was detected within the interatrial septum on two-dimensional transthoracic echocardiography during the postoperative period and the patient was referred to our clinic. Open heart surgery was performed and a hydatid cyst that involved the interatrial septum was enucleated. The cyst wall was sutured to the interatrial septum. No complications developed during the postoperative period. The patient was discharged on the fifth day of hospitalization and medical therapy was started with albendazole.

Cardiac hydatid disease is very rare, even in endemic regions. Clinical manifestations included chest pain, anaphylactic shock, constrictive pericarditis, congestive heart failure, and arterial embolism. Surgery is the exclusive therapy, where the cysts are excised during open-heart surgery. The surgical approach therefore must be performed carefully, given the potential complications that surgery may bring. Because of the risk of potentially lethal complications, early diagnosis and definitive treatment are important. A 32-year-old male patient was admitted with chest pain, weight loss, lethargy, and dizziness. On the transesophageal echocardiography study, a cystic mass (2.5 x 3 x 4.5 cm in dimension adjacent to the left ventricular posterior wall) that was divided into two by a septum was noted. Diagnosis of hydatidosis was confirmed with serologic tests (ELISA and indirect immunofluorescence). Echinococcosis, also known as hydatid disease, is common in several regions of the world, for example, the Mediterranean countries, the Middle East, South America, and East Africa. While performing pericystectomy in the anterior left ventricular wall, we noticed that there were three cysts, contrary to the preoperative diagnosis pointing a single one, and it was impossible to effectively complete the procedure without compromising anterosuperiorly displaced left anterior descending artery (LAD). We decided to go on bypass, arrest the heart, and complete the pericystectomy at the cost of injuring LAD and grafting the left internal mammary artery to LAD. Microscopic examination of the cyst showed a germinal layer and an avascular, eosinophilic, chitinous layer that confirmed the diagnosis of hydatid cyst. The patient was discharged on the fifth postoperative day on albendazole medication.

Surgery remains the gold standard for the treatment of patients with echinococcosis, despite significant economic costs, advances in medical treatment and interventional radiology; in the past decades there has been a tendency toward laparoscopic surgery. We present a 66-year-old patient, from a rural area, who was admitted to our service complaining of spontaneous and palpatory pains in the right hypocondrium, headaches and dizziness. Abdominal CT scan highlighted 2 round calcified tumors, one of 7.2 cm diameter (VIII(th) segment) with liquid densities, and the other one localized higher, with a diameter of 2.3 cm (IV(th) segment). Under general anesthesia, after the neutralization of the content of the cyst with hypertonic saline irrigation, we performed laparoscopic partial pericystectomy of the VIII(th) segment liver cyst and total laparoscopic cystectomy of the IV(th) segment liver cyst. Postoperative evolution was favorable without biliary fistula formation, postoperative infections or cystic cavities abscesses. Laparoscopic surgery seems to be effective and safe for uncomplicated cysts in accessible segments of the liver, combined with adjuvant albendazole therapy to reduce complications and postoperative morbidity, but the procedure has its own disadvantages such as a limited area of surgical manipulation.

Echinococcus granulosus is the causative agent of cystic echinococcosis (CE), which is distributed all around the world. CE is one of the most important global parasitic infectious diseases, both in humans and animals. This parasite causes hydatid cysts that can be lodge at different organs of host such as liver, lung even in heart and brain which may lead to death. Presently, numerous scolicidal chemical agents have been administrated for inactivation of the hydatid cyst contents. Because of increasing resistance and adverse effects of medications include abnormalities of liver function, abdominal pain, diarrhea, nausea, vomiting, dizziness, and headache; there is a need to find alternative therapies either with the least or without side effects. Recently, there is a high tendency among researchers to evaluate and present herbal plants as alternative option due to being inexpensive, easy available, low side effects and toxicity. Till now, many efforts have been conducted on herbal extracts against protoscolices of hydatid cysts throughout the world. Therefore, the current review systematically searched the following electronic databases: PubMed, Science Direct, Scopus, and Google Scholar on published papers according to the keywords. In addition, a comprehensive list of medicinal plants was prepared and some of these herbal plants which showed the best efficacy and promising results are discussed elaborately.

A complicated case of echinococcosis with multiple organ involvement is reported in a 53-year-old businessman who frequently traveled overseas, including China, Russia, and Kazakhstan from 2001 to 2007. The patient was first diagnosed with a large liver cyst during a screening abdomen ultrasonography in 2011, but he did not follow up on the lesion afterwards. Six years later, dizziness, dysarthria, and cough developed, and cystic lesions were found in the brain, liver and lungs. The clinical course was complicated when the patient went through multiple surgeries and inadequate treatment with a short duration of albendazole without a definite diagnosis. The patient visited our hospital for the first time in August 2018 due to worsening symptoms; he was finally diagnosed with echinococcosis using imaging and serologic criteria. He is now on prolonged albendazole treatment (400 mg twice a day) with gradual clinical and radiological improvement. A high index of suspicion is warranted to early diagnose echinococcosis in a patient with a travel history to endemic areas of echinococcosis.

A 60-year-old man was referred to the interventional pulmonology clinic with a large right-sided intraparenchymal lung mass and a second, smaller lesion in the left lower lobe, accompanied by intermittent haemoptysis, fever, chills, productive cough of white phlegm as well as dizziness and weakness. He had presented previously and was being evaluated for the possibility of malignancy. Investigations had revealed 'hooklets' (protoscolices) of hydatid cysts, most likely representing the parasite Echinococcus Successful surgical excision of the affected lobe, lung decortication, partial pleurectomy and pneumolysis of the adhesions was performed, along with long-term antiparasitic therapy. The initial differential diagnosis for this patient was challenging and required multimodal investigations. The patient made good recovery and continued to be followed by infectious disease specialists for management of antiparasitic therapy.

A 7-year-old boy referred to our emergency department complaining of headache, nausea, vomiting, dizziness, generalized fatigue, ataxia and diplopia. Neurological exam showed bilateral papilledema and ataxic gait. Routine blood test, plain chest x-ray and abdominal ultrasonography were normal. Brain computed tomography (CT) scan and magnetic resonance imaging (MRI) revealed well-defined intra-axial unilocular cystic lesion in the left cerebellar hemisphere, causing mass effect on brain stem and fourth ventricle with associated tonsillar herniation and mild obstructive hydrocephalus. The authors started the treatment with Albendazole and the patient was operated with left sub-occipital craniotomy. Cyst was delivered with intact capsule. Postoperative period was uneventful and patient's symptoms improved totally after 1 week. Histopathologic examination confirmed the diagnosis of hydatid cyst.
