Primary hydatid disease of chest wall mimicking chest wall mass-case report

•

Hydatid disease can affect chest wall like many other organs.

•

Primary hydatid disease of chest wall can present as a chest wall mass.

•

Treatment of chest wall hydatid disease is surgery.

•

Anti-parasite drugs and scolicidal agents can also be used.

Introduction

Hydatid cyst is a parasitic disease caused by echinococcus granoulosis. It is endemic in Mediterranean areas, south America, north Africa and Australia. The disease is most common in the liver and then in lung, the chest wall involvement by hydatid disease is a very rare condition.

Presentation of case

We present a case of chest wall mass in a 65-years old man, who intra operatively diagnosed as primary hydatid cyst. Cystectomy done and patient followed up for 2 months.

Discussion

The diagnosis of echinococcus infection mainly depends on the clinical history of the patient, serologic tests, and diagnostic radiological findings. Operative procedures for chest wall hydatid disease are cystectomy, cystotomy, evacuation, and chest wall resection.

Conclusion

Chest wall hydatid disease should be considered in the differential diagnosis of chest wall masses even in a patient who has not been operated for hydatid disease.

Optimization of fluoride-containing bioactive glasses as a novel scolicidal agent adjunct to hydatid surgery

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.
