In this study, the effect of prophylactic anti-inflammation on the development of smoke-induced emphysema was investigated. Young male guinea-pigs aged 1.5-2 months (weighing 198.3+/-26.9 g) were randomly divided into 4 groups: group A (cigarette smoke exposure only), group B (cigarette smoke exposure plus pentoxifylline-rich (PTX, 10 mg/d) forage feeding), group C (cigarette smoke exposure plus intermittent cortical steroid injection (Triamcinolone acetonide, 3 mg, i.m., every three weeks) and control group (group D: animals with sham smoke exposure, raised under the same conditions). Animals in group A, B and C were exposed to smoke of cigarettes for 1 to 1.5 h twice a day, 5 days a week. All animals were killed at the 16th week and followed by morphometrical analysis of the midsagittal sectioned lung slices. Smoke exposure of 16 weeks resulted in visible emphysematous development in Group A but not in Group B and C. It was evidenced by the indicator of air-space size, mean linear intercept (Lm): 120.6+/-16.0 microm in Group A; 89.8+/-9.2 microm in Group B and 102.4+/-17.7 microm in Group C. The average Lm in either group B or group C was shorter than that in Group A (ANOVA and Newman-Keuls test, F=8.80, P=0.0002) but comparable to that (94.8+/-13.2 microm) in group D (P>0.05). It is concluded that long-term prophylactic anti-inflammation inhibits pulmonary emphysema induced by cigarette smoking in the guinea pigs.

A pneumocele is an abnormal dilatation of a paranasal sinus, most commonly affecting the frontal sinus. Although the etiology of pneumocele is not entirely known, several causative factors have been suggested including trauma, surgery, tumor and infection. We report here a case of post-traumatic pneumocele of the frontal sinus following a head trauma.

One case of pneumoscrotum associated with spontaneous colon perforation was reported. The patient was a 66-year-old man, presented with high temperature, mild abdominal pain and an enlarged scrotum. Physical examination revealed scrotal swelling, abdominal tenderness Case Report and muscular defense. Computed tomography (CT) of the abdomen showed swelling and pneumatosis of the left major psoas and iliopsoas muscles, and ultrasound found subcutaneous emphysema of the scrotum. Surgical investigation discovered a retroperitoneal perforation in the descending colon connected with a huge retroperitoneal vomica and scrotal sac. Spontaneous colon perforation induced pneumoscrotum is rare clinically. It may present as colon perforation, which calls for special attention.

OBJECTIVE: To discuss the etiology, diagnosis, treatment, and prevention of pneumomediastinum or pneumothorax during the removal of bronchial foreign bodies in children. METHODS: We analyzed the clinical data of 10 cases of pneumomediastinum or pneumothorax during the removal of bronchial foreign bodies in children. RESULTS: Two patients died and the other 8 were cured. CONCLUSION Pneumomediastinum or pneumothorax is mainly caused by the intrapulmonary hyper-pressure and fracture of pulmonary bubbles. The prognosis of pneumomediastinum or pneumothorax is closely related to such factors as correct and punctual diagnosis and quick removal of the airway obstruction.
