Background: According to previous data on asthma in the English literature, there are some results that show encouraging effects of acupuncture improving pulmonary function in asthma patients. We designed a prospective randomized crossover controlled study to determine the efficacy of acupuncture in asthma patients. Methods: Eighteen asthma patients with bronchodilator response > 20% improvement of forced expiratory volume in 1 second (FEV1) were initially randomly assigned to receive 1 performance of real acupuncture (RA) or sham acupuncture (SA) in a blinded manner. After a washout period, the patients were crossed over. Spirometry was done and recorded before and after acupuncture. Results: Sixteen of 18 patients completed the study. The mean (± SD) FEV1 values before and after RA were 1.52 ± 0.45 L and 1.67 ± 0.40 L, respectively (p < 0.001). The mean (± SD) FEV1 values before and after SA were 1.49 ± 0.40 L and 1.49 ± 0.41 L, respectively (p = 0.838, not significant). The percentage change in FEV1 values after RA was better than after SA (RA, 11.57 ± 8.11%; SA, 0.32 ± 7.76%; p = 0.003), while the bronchodilator response of FEV1 from simple inhalation bronchodilator was better than that for RA (p < 0.001). Conclusion: In asthma patients, acupuncture treatment may result in immediate improvement of FEV1, but the degree of improvement is less than that from inhalation bronchodilator.

Bloody pleural effusion is rarely associated with endometriosis. To effectively treat this condition, it is important to differentiate the malady from other common diseases such as malignancy or tuberculosis. We describe the case of a 40-year-old multiparous female featuring right-sided hemothorax presenting with right shoulder pain and progressive shortness of breath for the preceding 2 months. Thoracoscopy disclosed grossly negative findings apart from multiple small pores in the right hemi-diaphragm with blood clots within them. Examination of the thoracoscopic biopsy specimens showed chronic pleuritis without evidence of malignancy or tuberculosis. Pelvic endometriosis was considered a possible diagnosis according to the results of abdominal computed tomography (CT) scan, transvaginal sonography, and the results of dilatation and curettage. Periodic episodes of symptoms concurrent with menstruation led to the suspicion of a relationship between these conditions in our patient. Despite the patient undergoing an abdominal total hysterectomy and adhesiolysis without salpingo-oophorectomy, recurrent right-sided bloody pleural effusion developed 1.5 months subsequent to surgery. As a consequence, danazol (400 mg/day) was maintained because of the endometriosis associated with pleural effusion. One year of regular follow-up later, there was no evidence of recurrent pleural effusion. We considered that the bloody pleural fluid arose via seepage from the pelvic endometriosis through the pores of the right hemi-diaphragm during menstruation.

There are some encouraging results in the English literature that show acupuncture resulting in an immediate improvement in pulmonary function, but there are also studies that have not demonstrated any benefit. We present 3 patients with persistent asthma who experienced immediate bronchodilatation after acupuncture without the use of any short-acting bronchodilator. After needle stimulation on selected acupoints, clinical symptoms such as dyspnea and wheezing improved. Pulmonary function test showed immediate improvement in forced expiratory volume in 1 second (FEV1), more than 20% as compared with baseline FEV1. Pulmonary function returned to baseline within 4 hours after acupuncture in 2 patients. From our observations of these 3 asthma patients, acupuncture may improve clinical dyspnea symptoms and performance on pulmonary function tests. Further large-scale controlled studies should be conducted to determine the effectiveness of acupuncture in the treatment of asthma.
