Leukoplakia associated with renal tuberculosis in the chemotherapeutic era.

The association of renal tuberculosis and leukoplakia of the renal pelvis was quite common in the prechemotherapy era of tuberculosis but has apparently not been seen since effective drugs became available. Despite a prompt response of the tuberculosis to chemotherapy the leukoplakia formation with intermittent passage of keratinised material continued. Surgical removal of the accumulated material was of no lasting benefit.

Surgical complications of cervical and mediastinal tuberculous adenitis in an infant.

An infant whose miliary tuberculosis was resolving after five months of chemotherapy developed a tuberculous cervical lymphatic abscess followed shortly thereafter by life-threatening tracheal compression from enlarged tuberculous mediastinal nodes. Both of these complications required surgical drainage. Chemotherapy alone may be ineffective in the management of lymphadenitis caused by Mycobacterium tuberculosis.

Mediastinal histoplasmosis with esophageal abscess. Two case reports.

Two patients were seen with Histoplasma capsulatum infection of mediastinal nodes which had eroded into the esophagus to produce dysphagia. Fungal serologies were of value in the diagnosis in one of the patients. Both patients responded well to amphotericin B therapy. A traction diverticulum was noted to follow healing in 1 patient.

The tuberculin tine and Mono-Vacc tests in the patient with active tuberculosis.

Eighty-four patients with culture-positive Mycobacterium tuberculosis infections of the lung were evaluated with the Mono-Vacc and tine tuberculin skin tests. A previous report indicated that false negative reactions with the tine may occur in up to 6 per cent of patients when it is used as a screening device for tuberculin sensitivity. However, as indicated by this study, it is unlikely that either screening tests would miss active tuberculous infection; no false negatives occurred in the 84 patients.

Cough dynamics in the post-thoracotomy state.

A series of 24 adult male patients undergoing thoracotomy were found to have a reduction in their cough pressures in the immediate postoperative period to 29 percent of their preoperative values. Cough pressures still averaged only 50 percent of control values one week following surgery, with slow return toward normal over the ensuing three weeks. Pain associated with the surgical wound appeared to be primary factor in the patients' inability to cough effectively. The degree of impairment appeared to be related to the extent of the procedure, pressures being altered less in those with limited incision thoracotomies. Ultrasonically nebulized water mist was found to be effective in all but one patient in inducing significantly higher cough pressures and more effective sputum expectoration. Its use should be considered as a simple method of inducing more effective coughs in the postoperative patient.

The Chanute histoplasmosis epidemic. New variations of urban histoplasmosis.

An epidemic of acute histoplasmosis occurred in a long-established residential neighborhood in central Illinois. Ten of the 28 individuals living in the five duplex buildings comprising the housing project had evidence of acute infection. The epidemic was unusual in that the infections apparently occurred as the result of adults tending their gardens and children playing under and about the tress of the area. No specific event, such as a construction project or the demolishing of an old building, was involved as a point source, as has usually been observed in past epidemics. The infections occurred sporadically over a summer and probably resulted from exposure to any one of several sites where the fungal organisms were shown to exist in the housing area.
