Hepatopulmonary hydatidosis in a ten-year-old girl: a case report

<p>Abstract</p> <p>Introduction</p> <p>Hydatid disease is a parasitic infection caused by the tapeworm <it>Echinococcus granulosus </it>and is characterised by cystic lesions in the liver and lungs. Concomitant pulmonary and hepatic localization of hydatid cysts in childhood is unusual and represents a distinct clinical entity called hepatopulmonary hydatidosis.</p> <p>Case presentation</p> <p>A ten-year-old Caucasian girl, a permanent resident of rural Greece, was admitted to hospital reporting a nonspecific symptomatology compatible with a diagnosis of viral infection. Chest radiography revealed a large homogenous circular opacity in the right lung field. On the basis of imaging studies, a diagnosis of hydatidosis was made with synchronous hepatic and pulmonary involvement, successfully managed through a single-stage transthoracic surgical approach.</p> <p>Conclusion</p> <p>This case report highlights the necessity of realizing that hydatid disease continues to be a public health problem, which often remains asymptomatic for years. Therefore, the presence of any homogeneous cystic spherical opacity on routine chest radiography should raise the suspicion of hydatid disease, mainly in endemic areas such as Greece. General practitioners and physicians involved in pediatric care need to be familiar with the diagnosis and management of the variable clinical manifestations of hydatid disease. Taking into consideration that hepatopulmonary hydatidosis represents a special entity that requires a different therapeutic approach may positively affect its economic and social-related burden.</p

A comprehensive overview of radioguided surgery using gamma detection probe technology

The concept of radioguided surgery, which was first developed some 60 years ago, involves the use of a radiation detection probe system for the intraoperative detection of radionuclides. The use of gamma detection probe technology in radioguided surgery has tremendously expanded and has evolved into what is now considered an established discipline within the practice of surgery, revolutionizing the surgical management of many malignancies, including breast cancer, melanoma, and colorectal cancer, as well as the surgical management of parathyroid disease. The impact of radioguided surgery on the surgical management of cancer patients includes providing vital and real-time information to the surgeon regarding the location and extent of disease, as well as regarding the assessment of surgical resection margins. Additionally, it has allowed the surgeon to minimize the surgical invasiveness of many diagnostic and therapeutic procedures, while still maintaining maximum benefit to the cancer patient. In the current review, we have attempted to comprehensively evaluate the history, technical aspects, and clinical applications of radioguided surgery using gamma detection probe technology

Chronic inflammatory demyelinating polyneuropathy in an eight year old girl

Chronic inflammatory demyelinating polyneuropathy is an acquired neuropathy which is rarely seen pediatric patients. It is characterised by chronic progressive or relapsing remitting weakness. The prognosis in childhood is good compared to adult patients. We present an eight year old girl with chronic inflammatory demyelinating polyneuropathy whose response to prednisone treatment was excellent. The diagnosis of chronic inflammatory demyelinating polyneuropathy should not be missed because it is one of the acquired neurologic disorders that respond to treatment

Detection of circulating melanoma cells by a two-marker polymerase chain reaction assay in relation to therapy.

Malignant melanoma is one of the most rapidly increasing cancer types, and patients with metastatic disease have a very poor prognosis. Detection of metastatic melanoma cells in circulation may aid the clinician in assessing tumor progression, metastatic potential, and response to therapy. Tyrosinase is a key enzyme in melanine biosynthesis. The gene is actively expressed in melanocytes and melanoma cells. Melan A is a differentiation antigen that is expressed in melanocytes. The presence of these molecules in blood is considered a marker for circulating melanoma cells. In this study, we analyzed the usefulness of this marker combination in evaluating the response to therapy in the blood of 30 patients with malignant melanoma. Circulating cells were detected by a reverse-transcriptase-polymerase-chain reaction. The tyrosinase expression was observed in 9 (30%) patients and Melan A in 19 (63.3%) patients before therapy. Following treatment, the tyrosinase mRNA was detected in only one patient, while Melan A transcripts were still present in 14 patients. We suggest that this molecular assay can identify circulating melanoma cells that express melanoma-associated antigens and may provide an early indication of therapy effectiveness
