[High resolution CT of interstitial lung diseases].

High-resolution CT images were assessed in 39 patients with confirmed interstitial lung disease. 22 patients with fibrosing alveolitis, 12 patients with lymphangitic spread of tumour and 5 patients with lymphangioleiomyomatosis of the lung were included. In fibrosing alveolitis the dominant features on HR-CT were honeycomb cysts with concomitant fibrosis in a predominantly peripheral subpleural distribution. In contrast to this the patients with LAM showed cystic lesions without any predominance--throughout the lung fields and without any fibrotic changes. In lymphangitic spread of tumour, polygonal lines and septal lines as well as nodules were found along the bronchovascular bundles. The patterns seen on HR-CT of the thorax correlate extremely well with the underlying pathology and make it possible to differentiate between the three disease entities by means of characteristic features.

Prevention of acute adenolymphangitis in brugian filariasis: comparison of the efficacy of ivermectin and diethylcarbamazine, each combined with local treatment of the affected limb.

Acute attacks of adenolymphangitis (ADL) not only force patients with lymphatic filariasis to seek medical attention but also hasten the progression of filarial oedema. Patients with filariasis-associated ADL are currently treated with repeated courses of the antifilarial drug diethylcarbamazine (DEC), with or without antibiotics and anti-inflammatory agents. In this double-blind, placebo-controlled study, the efficacy of local treatment of the affected limb combined with repeated doses of ivermectin or DEC, in preventing the occurrence of ADL in Brugia malayi lymphatic filariasis, was examined. Overall, 120 patients who had each had at least two ADL attacks in the previous year were each admitted to the study at the time of an ongoing episode of ADL. The patients were randomly allocated to receive 12, monthly treatments of ivermectin (400 micrograms/kg), DEC (10 mg/kg) or placebo, in addition to local care of the affected limbs. There was a significant reduction in the frequency of ADL attacks in each of the three groups during the 2-year study period (P < 0.001 for each comparison). Most importantly, there were no significant differences in frequency of attacks between the three groups, either at the end of the treatment phase or at the end of the post-treatment phase (P > 0.15 for each comparison), suggesting that foot care combined with appropriate use of local antibiotics or antifungals is adequate to reduce the number of ADL attacks. The implications of these observations for planning morbidity control in lymphatic filariasis are discussed.

A double-blind, placebo-controlled study of the efficacy of oral penicillin, diethylcarbamazine or local treatment of the affected limb in preventing acute adenolymphangitis in lymphoedema caused by brugian filariasis.

Acute attacks of adenolymphangitis (ADL) contribute significantly to the morbidity seen in cases of filarial lymphoedema. Such cases are now being treated with multiple courses of the antifilarial drug diethylcarbamazine (DEC), either alone or in combination with antibiotics or anti-inflammatory drugs, based on anecdotal experience. In this, the first double-blind, placebo-controlled study, 150 patients with lymphoedema caused by brugian filariasis, each of whom recalled two or more ADL attacks in the previous year, were enrolled on a comprehensive foot-care programme. Each was also randomly allocated to one of the following five daily regimens (30 patients/regimen) for 1 year: 800 mg oral penicillin; 1 mg DEC/kg; 800 mg oral penicillin plus 1 mg DEC/kg; local antibiotics; or placebo. Each patient was followed up for another year. For each regimen group (including the placebo group), the number of ADL attacks in the treatment year was significantly less than that in the year prior to treatment (P < 0.001). Although, in all but the placebo group, there was a slight increase in the number of episodes in the follow-up year compared with the treatment year, the increase was only significant in the two groups given penicillin. Of all the treatments tested therefore, foot care seems to play the most important role in the prevention of ADL attacks. Additional benefit may accrue from local or systemic antibiotic use in those with high grades of oedema, but antifilarials have no place in the prevention of ADL attacks in an individual patient. These observations should help in the rational management and prevention of ADL attacks in filarial lymphoedema, so that the progression of the disease may be halted and morbidity reduced.

Outbreak of sporotrichosis among tree nursery workers.

In spring 1994, an outbreak of sporotrichosis occurred at a tree nursery in Florida; 9 (14%) of 65 workers involved in production of sphagnum moss topiaries developed lymphocutaneous sporotrichosis. A cohort study of all 65 employees was conducted to identify risk factors for sporotrichosis, and an environmental investigation was done. The risk of sporotrichosis increased significantly with the duration of working with sphagnum moss (P < .05), in particular with filling topiaries (P < .05), and with having less gardening experience (P < .05). Wearing gloves was protective (P < .005). Sporothrix schenckii was cultured from patients and sphagnum moss used in topiary production. Use of restriction fragment length polymorphism revealed an identical pattern for patient isolates that was different from the patterns of environmental isolates. Physicians should be aware of sporotrichosis in patients with ulcerative skin lesions who have a history of occupational or recreational exposure to sphagnum moss.

The identification of a rabbit-transmitted cervical toxoplasmosis mimicking malignant lymphoma.

A case is presented of acquired cervical toxoplasmosis occurring in a 43-year-old male, which clinically mimicked malignant lymphoma. The histopathology of this case was probable toxoplasmic lymphadenitis. Serologic tests and the use of FITC-labeled antibodies revealed high levels of specific IgG antibodies in the serum and toxoplasmic antigens in paraffin sections of the patient, respectively. During survey of the infection route, it was learned that the patient's pet rabbit and three other rabbits of the same family line had cervicofacial lumps. The pet rabbit had high levels of toxoplasmic antibodies. Immunofluorescence tests on the infraorbital lump also revealed Toxoplasma gondii. Therefore, it was concluded that in this case the rabbit had transmitted Toxoplasma to the patient. The authors know of no other reports of toxoplasmosis transmitted by or through rabbit to human.

Pulmonary lymphangitic sarcomatosis from cutaneous angiosarcoma: an unusual presentation of diffuse interstitial lung disease.

Pulmonary lymphangitic sarcomatosis (PLS) is not much recognized clinically although it shows similar pathological patterns and diagnostic features to pulmonary lymphangitic carcinomatosis (PLC). We report a case with hand angiosarcoma whose chest X-ray findings revealed a diffuse interstitial pattern consistent with lymphangitic spreading. The final diagnosis was made by open lung biopsy. The clinical, diagnostic and pathological features of this disease process are reviewed.

Axillary-contralateral brachial artery bypass for arm ischemia.

A right axillary to left brachial arterial bypass (saphenous vein) was used in the treatment of a left subclavian artery obstruction secondary to radical mastectomy and irradiation 28 years previously. The axillary bypass was chosen over other surgical approaches because of its simplicity and efficacy.

Comparison of lymphedema following incontinuity and discontinuity groin dissection.

Wide excision of primary malignant melanoma en bloc with regional lymphadenectomy decreases the incidence of regional recurrence as compared with a discontinuous dissection. The more extensive soft tissue defect of the incontinuity procedure is of concern since major lymphatics are often ablated from the ankle region up to the aortic bifurcation. This problem was studied in 81 currently living patients, all of whom had been operated upon for primary melanoma located below the distal thigh. Measurable lymphedema was found in 64% who had had the incontinuity procedure and 69% in the discontinuity group. The incidence of advanced lymphedema (greater than two inches) was 23% and 36%, respectively. All patients with advanced edema had been operated upon more than 3 years ago. Eighty per cent of patients operated upon more than 5 years ago had lymphedema. Wound complications had occurred in 41% of the patients in the incontinuity group and 42% in the discontinuity group, but this did not affect the incidence of edema. The clinical findings are readily explainable on the basis of lymphangiographic data.

Transabdominal lymphography after intraperitoneal injection of Rous virus in newborn rats.

Newborn rats were inoculated in the peritoneal cavity with Rous sarcoma virus (Schmidt-Ruppin strain). They were studied lymphographically and histologically after various intervals of time. As a result of lesions of the lymph vessels and nodes, the lymphatic drainage of the peritoneal cavity was increasingly impaired. Pleural effusion developed as a result of leakage through the walls of the lymphatics. The passage through the lymph nodes was blocked and large lymph cysts arose in the mediastinum and retroperitoneally.
