It was demonstrated that patients with coronary heart disease with coronary angiographically documented stenosing coronary atherosclerosis and frequent episodes of angina pectoris had significantly higher pain threshold in response to electric skin irritation and greater defense unconditioned flexor reflex R-III threshold than healthy subjects and patients with chest pain of extracoronary genesis.

Rhodamine B is a red colored dye that is used in cosmetic products. We report a case of 17 patients who were exposed to aerosolized Rhodamine B inside a maintenance shop. The mean duration of exposure was 26 minutes (range 2-65). Sixteen of the patients (94%) complained of acute symptoms including: burning of the eyes (82%), excessive tearing (47%), nasal burning (41%), nasal itching (35%), chest pain/tightness (35%), rhinorhea (29%), cough (29%), dyspnea (29%), burning of the throat (24%), burning/pruritic skin (24%), chest burning (12%), headache (6%), and nausea (6%). All of the patients had resolution of their symptoms within 24 hours (less than 4 hours in 63%). Acute exposure to Rhodamine B resulted in transient mucous membrane and skin irritation without evidence of serious sequellae.

The pulmonary function and symptoms of 125 workers exposed to carbon black in dry cell battery and tire manufacturing plants were investigated. There was no significant difference in the pulmonary function of the subjects in the two plants. There was good agreement in the symptoms reported in the two different factories: cough with phlegm production, tiredness, chest pain, catarrh, headache, and skin irritation. The symptoms also corroborate those reported in the few studies on the pulmonary effects of carbon black. The suspended particulate levels in the dry cell battery plant ranged from 25 to 34 mg/m3 and the subjects with the highest probable exposure level had the most impaired pulmonary function. The pulmonary function of the exposed subjects was significantly lower than that of a control, nonindustrially exposed population. The drop in the lung function from the expected value per year of age was relatively constant for all the study subgroups but the drop per year of duration of employment was more severe in the earlier years of employment. This study has underscored the need for occupational health regulations in the industries of developing countries.

The health impact of exposure to sawdusts on 59 sawmill workers from southwest Nigeria was studied. Workers were chosen by a two-stage random sampling method from 15 privately owned sawmills. Peak flow and spirometric measurements were obtained from all workers. They also underwent a structured questionnaire which elicited occupationally related symptoms. Age and sex matched controls consisting of 199 workers from similar socio-economic backgrounds as the subjects underwent similar questionnaire and lung function tests. Results showed a high prevalence of respiratory symptoms, principally cough, chest pain and sputum production, among the workers. Most of the workers also had high prevalence of conjunctivitis, skin irritation and hearing difficulties when compared with controls. Pulmonary function parameters were also significantly lower (p < 0.05 in sawmill workers than controls). Although a large number (94.9%) of the workers were aware of the potential hazards of exposure to sawdusts, less than 20% wore protective masks. Our study highlights the need for health and safety regulation in the workplace. There is also a need for improved methods of dust control in factories with high levels of dust particulates, particularly in the developing world.

External electrocardiographic loop recording permits extended cardiac rhythm monitoring and ECG storage before and after device activation. The purpose of the study was to assess the diagnostic yield of external loop recorders in patients with more than two syncopal events within the last 6 months and a negative tilt table test. Twenty-four consecutive patients (51 +/- 14 years, male n = 9) were enrolled with 3 +/- 4 recurrent syncopal events within the last 6 months and no overt structural heart disease. The loop recorder CardioCall continuously records a two-channel ECG via skin electrodes. When activated, up to 4.5 minutes of the ECG preceding activation is stored. The time between tilt table testing and monitoring was 5 +/- 4 weeks. The average monitoring period covered 50 +/- 22 days. Recording was either unsuccessful or terminated prematurely in 5 patients. The reasons were skin irritation secondary to the electrodes in two patients, cable damage in one patient, and two patients inadvertently erased the stored data when replacing the batteries. Fourteen patients activated the loop recorder at least once. Symptoms leading to device activation were syncope (n = 1), dizziness (n = 11), feeling unwell (n = 7), palpitations (n = 5), headaches (n = 1), and chest pain (n = 1). The loop recorder documented sinus tachycardia during the syncopal event. Sinus tachycardia was also observed in 7 other patients, and atrial flutter in two patients. Eight patients had recurrent syncope with two patients experiencing syncope prior to the monitoring period, one syncope occurred in a patient who inadvertently erased the stored data, one event coincided with sinus tachycardia, and 4 (17%) patients had syncope during 15 +/- 10 months after termination of loop monitoring. The external loop recorder was not very useful for arrhythmia detection in patients with syncopal events, no overt heart disease, and a negative tilt table test because the cardiac rhythm was stored in only 1 of 8 (13%) patients with recurrent syncope. Reasons for the low diagnostic yield of external loop recorders were infrequent syncopal events after the baseline evaluation, with rare events during the limited monitoring period in particular, and premature termination or unsuccessful recording in 21% of patients.
