Mucinous peritoneal carcinomatosis from a primary gastrointestinal malignancy is a lethal condition that has few treatment options with the use of surgery, chemotherapy or radiation therapy. Recent advances in hyperthermia technology and in knowledge of the natural history of this disease has suggested the possible utility of hyperthermia in the application of aggressive local-regional therapy. Radiofrequency (RF) hyperthermia to the whole abdomen, to the hemithorax, or to an isolated mucinous tumour deposit obstructing the gastrointestinal tract was used in patients with disseminated mucinous adenocarcinoma of appendiceal origin. There were 228 hyperthermia treatments in 21 patients, with a median of 10 treatments per patient. The maximum number of treatments was 26, and minimum was one. For the first six hyperthermia treatments, escalating doses of deep hyperthermia (41-45 degrees C) was monitored with multiple sensor internal temperature probes and a single sensor subcutaneous temperature probe. After reaching a maximal hyperthermia treatment, this was maintained for all subsequent treatments. Initially, the maximal temperature allowed in tumour and subcutaneous tissue was 43 degrees C. After 50 hyperthermia treatments, this was changed to 45 degrees C. If disease stabilization or response was insufficient and maximal tolerable hyperthermia had been established, the frequency of treatment was increased from every 4 weeks to every 2 weeks, and escalating doses of mitomycin C at 8 mg/m2 were added to the regimen. Mitomycin C was infused during the hyperthermia treatment. For the first 165 treatments, patients were monitored just before and 10 days after hyperthermia with a complete blood count and a full battery of laboratory tests including amylase and lipase. Response was monitored by carcinoembryonic antigen assays on a monthly basis and CT scans on a 6 monthly basis. None of the 21 patients included in this study died, required intensive care, or required major surgical interventions as a result of hyperthermia treatments. One potentially life-endangering event was profound bradycardia and hypotension observed in a 76-year-old male receiving hyperthermia treatment to his right hemithorax. Two patients developed an enterocutaneous fistula (a frequent spontaneous event in this group of patients) while under treatment. No abnormal laboratory tests were observed in the first 165 hyperthermia treatments. Heat damage to normal tissue was limited to skin blisters in three patients and induration of the subcutaneous tissues in 10 patients. Skin pain on an analogue scale of 0-10 was scored by patients as a mean of 3.6 (range 0-8) before skin analgesia was routinely utilized. With anesthetic gel, the skin discomfort was greatly reduced. Prolonged abdominal pain for 4-20 days following treatment which required narcotic analgesia was seen in four patients. A complication rate of 62% was caused by the long-term indwelling temperature probe sheaths. Infection was observed in four patients, small bowel fistula in one, and dislodgement of the temperature probe sheath requiring repeat CT was necessary in seven patients. After maximal escalation of RF power in seven patients (33%), deep hyperthermia compatible with thermal destruction of tumour (> or = 43 degrees C for 45 min) was recorded in all subsequent treatments. In eight patients (38%), heat generation compatible with chemotherapy augmentation (41.5-43 degrees C) was consistently recorded. In six patients, non-therapeutic temperatures were recorded. There was no correlation of maximal tumour temperature, maximal subcutaneous tissue temperature and maximal RF power. With the use of skin anaesthetic there was no correlation of tumour temperature and the thickness of the subcutaneous layer of the skin. Progression was seen in 14 patients, and 11 of these patients died. No patients who showed disease stabilization have died with a minimum of 2 year follow-up. (ABSTRACT TRUNCATED)

We encountered 8 adult cases of pulmonary toxocariasis. Five were asymptomatic, 1 had transient chest pain, 1 suffered from arthralgia and migrating skin pain, and 1 had chest discomfort due to pneumothorax. Infection was associated with the consumption of raw liver with paratenic hosts in 5 patients. The cause was suspected to be contact with infected young dogs in 1 case and was undetermined in 2 cases. All 8 cases showed some abnormalities in their laboratory examination results including eosinophilia (>500/microl) and elevated IgE (>100 IU), and all had positive results in serological examinations for the larval excretory-secretory product of Toxocara canis. In 7 patients, excluding the patient with pneumothorax, chest computed tomography demonstrated multiple small pulmonary lesions, most of which were either nodules with halos, or ground-glass opacities. One patient recovered without medication, while the other 7 were treated with albendazole (ABZ) with good responses. Although the optimal duration of ABZ therapy has not been established, 4 weeks or longer seemed necessary to obtain a complete cure in pulmonary toxocariasis.
