Chemo-immunotherapy and immunological study in carcinoma of larynx and laryngopharynx.

Eighteen of 25 patients had squamous cell carcinoma in the supraglottic region. Anergy to skin test antigen (DNCB) and T-cell mitogen (PHA) was observed in 17 patients with laryngeal and laryngopharyngeal malignancies. Chemo-immunotherapy did not improve the skin reactivity to either agents. However, a rise in absolute T-cell counts was observed following combined therapy. Moreover, T-lymphopenia was detected in the patient group prior to therapy as compared to mean T-cell counts in normal control subjects.

Nasal myiasis: review of 10 years experience.

Nasal myiasis is a manifestation of the nasal cavities by larvae of the fly of genus Chrysomia. It is prevalent in tropical countries. Atrophic rhinitis is the most commonest predisposing factor for this condition. The maggots can cause extensive erosion of the nose, face and intra-cranial structures occasionally causing meningitis and death. Conservative management by packing the nose with a chloroform and turpentine (1:4) mixture followed by manual removal of the dead maggots is an effective method. Recurrence is known but partial closure of both nostrils to improve the condition of nasal mucosa is the important part of management.

In vitro and in vivo evaluation of change of local pH on bacteria in C.S.O.M.

An in vitro study has shown a high bactericidal activity of 2 per cent acetic acid. An in vitro study in 400 cases of C.S.O.M. has shown that conservative treatment of C.S.O.M. by pH change with 2 per cent acetic acid is better than antibiotic ear drops alone. However, combined therapy (pH change plus antibiotic ear drops) is definitely superior to single treatment by either of the two methods. Two per cent acetic acid is well tolerated by the middle ear mucosa except in 1 per cent cases, where its use had to be discontinued because of irritation. The use of 2 per cent acetic acid is highly recommended, particularly for poor nations, because of its negligible cost as compared to antibiotic ear drops.

Heat stress limits for the sedentary worker.

Performance on four sedentary tasks was monitored during temperatures of 85 degrees f, 95 degrees F, and 105 degrees F WBGT for work periods up to 2 hours. Results were compared with limits recommedned for occupational safety and health regulations. It is suggested that this limit is not a single line, but rather a range of temperture-time combinations. Further, man's compensating nature during short exposures supports a higher temperature limit for brief work bouts.
