Postpneumonectomy syndrome is a disease entity which arises after right pneumonectomy in left aortic arch and left pneumoncectomy in right aortic arch. This syndrome have a feature of severe mediastinal deviation and rotation, and induces severe respiratoy insufficiency. This syndrome is rare, but should be considered when pneumonectomized patient complaints who have severe dyspnea. In Samsung medical center, We report a sucessfully treated patient with postpneumonectomy syndrome, who had experienced right pneumonectomy at 1 years ago.

A clinical analysis was performed on 61 cases of patent ductus arteriosus experienced at Yeungnam University Hospital during 3 years period from April, 1984 to December, 1986. Of the 61 patient of PDA, 13 patients were male and 48 patient were female and age ranged 2 months to 26 years old with the average age of 9.4 years. The chief complaints on admission were frequent URI and dyspnea on exertion. diagnostic procedure were Doppler echocardiogram (in 53 among 61). Three postoperative complication were developed, but there was no operative mortality.

We present a case of 50 year old male patient with coexistence of Pneumothorax and Chilaiditi sign. Chilaiditi sign is an incidental radiographic finding of a usually asymptomatic condition in which a part of intestine is located between the liver and diaphragm; however, the term "Chilaiditi syndrome" is used for symptomatic hepatodiaphragmatic interposition. The patient had no symptoms of abdominal pain, constipation, diarrhea, or emesis. Incidentally, Chilaiditi sign was diagnosed on chest radiography. Pneumothorax is defined as air in the pleural space. Pneumothoraces are classified as spontaneous or traumatic. Spontaneous pneumothorax is labelled as primary when no underlying lung disease is present, or secondary, when it is associated with pre-existing lung disease. Our case is the rare in the literature indicating the coexistence of Chilaiditi sign and pneumothorax.

BACKGROUNDMedically unexplained dyspnea refers to a condition characterized by a sensation of dyspnea and is typically applied to patients presenting with anxiety and hyperventilation without underlying cardiopulmonary pathology. We were interested to know how anxiety triggers hyperventilation and elicits subjective symptoms in those patients. Using an imagery paradigm, we investigated the role of fearful imagery in provoking hyperventilation and in eliciting symptoms, specifically dyspnea.

METHODSForty patients with medically unexplained dyspnea and 40 normal subjects matched for age and gender were exposed to scripts and asked to imagine both fearful and restful scenarios, while end-tidal PCO(2) (PetCO(2)) and breathing frequency were recorded and subjective symptoms evaluated. The subject who had PetCO(2) falling more than 5 mmHg from baseline and persisting at this low level for more than 15 seconds in the imagination was regarded as a hyperventilation responder.

RESULTSIn patients with medically unexplained dyspnea, imagination of fearful scenarios, being blocked in an elevator in particular, induced anxious feelings, and provoked a significant fall in PetCO(2) (P < 0.05). Breathing frequency tended to increase. Eighteen out of 40 patients were identified as hyperventilation responders compared to 5 out of 40 normal subjects (P < 0.01). The patients reported symptoms of dyspnea, palpitation or fast heart beat in the same fearful script imagery. Additionally, PetCO(2) fall was significantly correlated with the intensity of dyspnea and palpitation experienced during the mental imagery on one hand, and with anxiety symptoms on the other.

CONCLUSIONSFearful imagery provokes hyperventilation and induces subjective symptoms of dyspnea and palpitation in patients with medically unexplained dyspnea.

OBJECTIVES: The MVV reflects subjective dyspnea, exercise capacity, postoperative complication. But, the MVV embodies certain disadvantages and is dependent on coordination, endurance and motivation. A timed vital capacity for calculation of an indirect maximal voluntary ventilation is used. We evaluated differences in prediction formulas for the MUV according to the status of ventilatory function. METHODS: Forty-seven normal subjects, 68 patients with obstructive ventilatory impairment, and 23 patients with restrictive ventilatory impairment were studied. The relationships between the MVV and Flow or time parameters in forced expiratory volume and flow volume curves were compared among normal subjects and patients with obstructive or restrictive ventilatory impairment. RESULTS: 1) High correlation coefficients(R>or=0.87) were found between the FEV0.5, 0.75, 1 and the MVV in 47 normal subjects and 91 patients with ventilatory impairment. 2) The MVV can be conveniently estimated from the FEV1 values. The following regression formulas for the prediction of the MVV were obtained. Normal: MVV=44.01 X FEV1-21.09(r(2)=0.771, SEE=11.085) Obstructive ventilatory impairment: MVV=38.34 X FEV1-4.58(r(2)0.812, SEE=4.816) Restrictive ventilatory impairment: MVV=45.20 X FEV1-3.80(r(2)=0.899, SEE=6.929). 3) There were significant differences in prediction formulas for the MVV obtained by FEV1 between each group (P<0.05). CONCLUSION: These results suggest that different prediction formulas for the MVV, by multiplying the FEV1 by a constant, are respectively required in normal subjects and patients with obstructive or restrictive ventilatory impairment.
