Objective: To determine the prevalence and risk factors of Giardia(G.) lamblia infections among the aboriginal community during the wet and dry seasons. Methods: A total of 473 stool samples from the aborigines in Temerloh, Pahang, Malaysia were collected during wet(n=256) and dry seasons(n=217). Smear of all the PVA-preserved stool samples were subjected to Trichrome staining and microscopic examination under 1 000 伊magnification(Nikon eclipse E100) for the detection of G. lamblia. Positivity was recorded based on the presence of G. lamblia in trophozoite and/or cyst forms. Results: The prevalence of giardiasis was 12.10% and 8.29% during the wet and dry season, respectively. Age of less or equal to 15 years old and presence of other family members with G. lamblia infection were found to be the significant risk factors to acquire G. lamblia infections during both seasons. Untreated water supply was the significant risk factor of giardiasis during the dry season. This study highlighted the possibility of anthroponotic transmission of G. lamblia during both seasons and waterborne transmission during the dry season in the aboriginal community. Conclusions: This study suggests that seasonal variation plays an important role in the prevalence and risk factor of G. lamblia infection in the aboriginal community. Therefore, close contact with Giardia-infected family members and water-related activities or usage of untreated water must be avoided to reduce the burden of G. lamblia infection in this community.

Heterotopic supradiaphragmatic livers are rare. A total of 23 cases of primary supradiaphragmatic livers have been reported in the literature. The clinical presentations of heterotopic supradiaphragmatic liver are variable. The simultaneous detection of intrathoracic accessory liver and pulmonary sequestration is extremely rare, and only one case has previously been reported. It is difficult to make a correct diagnosis preoperatively. We presented a 53-year-old woman with complaints of an intermittent, productive cough and dyspnea for two months that was refractory to medical treatment. She had no previous history of trauma or surgery. A chest radiograph only showed a widening of the mediastinum. Contrast-enhanced computed tomography of the chest revealed a well-circumscribed homogenous soft-tissue mass, approximately 4.35 cm × 2.5 cm × 6.14 cm in size, protruding through the right diaphragmatic crura to the right pleural cavity, attached to the inferior vena cava, esophagus and liver. There was no conclusive diagnosis before surgery. After the operation, we discovered that this patient was the first case of a supradiaphragmatic heterotopic liver, which passed through the inferior vena cava foramen and was coincidentally combined with an intralobar pulmonary sequestration that was found intraoperatively. We discussed its successful management with surgical resection via a thoracic approach and reviewed the published literature.
