The echinococcoses are chronic, parasitic diseases that are acquired after ingestion of infective taeniid tapeworm eggs from certain species of the genus Echinococcus. Cystic echinococcosis (CE) occurs worldwide, whereas, alveolar echinococcosis (AE) is restricted to the northern hemisphere, and neotropical echinococcosis (NE) has only been identified in Central and South America. Clinical manifestations and disease courses vary profoundly for the different species of Echinococcus. CE presents as small to large cysts, and has commonly been referred to as 'hydatid disease', or 'hydatidosis'. A structured stage-specific approach to CE management, based on the World Health Organization (WHO) ultrasound classification of liver cysts, is now recommended. Management options include percutaneous sterilization techniques, surgery, drug treatment, a 'watch-and-wait' approach or combinations thereof. In contrast, clinical manifestations associated with AE resemble those of a 'malignant', silently-progressing liver disease, with local tissue infiltration and metastases. Structured care is important for AE management and includes WHO staging, drug therapy and long-term follow-up for at least a decade. NE presents as polycystic or unicystic disease. Clinical characteristics resemble those of AE, and management needs to be structured accordingly. However, to date, only a few hundreds of cases have been reported in the literature. The echinococcoses are often expensive and complicated to treat, and prospective clinical studies are needed to better inform case management decisions.

The Echinococcoses: Diagnosis, Clinical Management and Burden of Disease.

BACKGROUND: There is increasing evidence that self-medications among pregnant women are common in many developing countries. Despite the adverse impact on pregnancy, there are few programs available for their control. The objective of this study was to assess the level of self-medication amongst Nigerian pregnant women in order to determine possible harmful effects on fetus. METHODS: Five hundred and eighteen 518 pregnant women, aged between 18 and 40 years, drawn from three General hospitals in Akwa Ibom State were assessed for self-medication and substance abuse using an instrument, adapted from a modified form of 117-item self-report questionnaire based on the WHO guidelines for students’ substance use survey. RESULTS: Of the 518 pregnant women assessed, 375 (72.4%) indulged in one form of self-medication or the other; 143 (27.6%) used only drugs prescribed from the antenatal clinic. A total of 157 (41.9%) pregnant women self-medicate fever/pain relievers; 47 (9.1%) mixture of herbs and other drugs; 15 (4.0%) sedatives; 13 (3.5%) alcohol; while 5 (1.3%) used kolanuts. Reasons for using these substances range from protection from witches and witchcrafts, preventing pregnancy from coming out, for blood; poor sleep, fever and vomiting and infections. There was a significant difference in the rate of using analgesics (X2=9.43, p=0.001); and antibiotic (X2=4.43, p=0.001) among pregnant women who were highly educated compared to those with little or no education. However, the level of education has no impact in the usage of native herbs. CONCLUSION: This study shows that self-medication is common among pregnant women in our environment. There is need for adequate education of pregnant women during antenatal clinics on the potential danger of self-medication so as to prevent child and maternal morbidity and mortality.

Self-Medication: potential risks and hazards among pregnant women in Uyo, Nigeria.

Background. Cerebral hydatid cysts account for up to 3.6% of all intracranial space-occupying lesions, in endemic countries. The vast majority of patients affected are children. Computed tomography (CT) and magnetic resonance imaging (MRI) have greatly contributed to a more accurate diagnosis of hydatids. However, correct pre-operative diagnosis still remains quite puzzling. Extirpation of the intact cyst is the treatment of choice, resulting in most cases to a complete recovery. Method. In our retrospective study, we have reviewed 76 cases of intra-cranial hydatid disease operated on in our hospital over a 22 year period. Presenting clinical symptoms and signs and the radiological findings on CT and MRI were documented. Albendazole was given preoperatively to patients with giant (>5 cm) or multiple cysts and postoperatively to all patients. The follow-up period ranged from 12 months to 22 years and the outcome was assessed using the Glasgow Outcome Scale (GOS). Findings. Sixty seven (95.7%) of our patients were children. Increased intracranial pressure and papilledema were the predominant findings in this group, whereas focal neurological deficits were most prevalent in adults. CT and MRI revealed round cystic lesions, isodense and iso-intense respectively to cerebrospinal fluid (CSF), with no rim enhancement or perifocal edema. Multiple cysts were identified in 3 cases. Extirpation of the cyst without rupture was accomplished in 56 patients (73.7%). Recurrences occurred in 19 patients (25%). 4 patients (5.3%) died within 6 months after surgery; 3 of these patients had multiple cysts and one died shortly after the operation due to anaphylactic shock following intra-operative rupture of the cyst. Conclusion. Long-term follow-up confirms that intracranial hydatid cysts should always be surgically removed without rupture; the outcome remains excellent in these cases. Correct preoperative diagnosis is vital for the successful outcome of surgery. A high index of suspicion is therefore required in endemic areas despite the availability of advanced neuro-imaging. Medical treatment with albendazole seems to be beneficial both pre- and post-operatively. Newer diagnostic methodologies, such as MR spectroscopy and MR diffusion weighted imaging, might lend themselves to the diagnosis of intracranial hydatid cysts.

Multiple intracranial hydatid cysts in a boy.

Among a series of 155 brain hydatid disease patients hospitalized between 1965 and 1998, 117 were children. The mean age was approximately 7.2 years, with a slight male predominance. Eighteen patients presented with another visceral localization. Symptoms and signs of intracranial hypertension are currently encountered (75%) followed by hemiparesis, epilepsy, mental changes, skull deformities and, more rarely, dyskinetic phenomenon. Brain hemispheric localization is the rule, with some exceptions. CT scans reveal an intra-parenchymal lesion with clearly defined, rarely enhanced margins. Medical treatment has virtually no place in the management of cerebral solitary cyst. Albendazole has been used in cases of multiple involvement, with controversial results. Surgical hydrostatic expulsion is the only effective treatment. Recovery is expected when the cyst is extracted completely unruptured.
