A prospective study of antisperm antibody development in acute epididymitis.

The association between acute epididymitis and development of antisperm antibodies was investigated by the gelatin agglutination technique in prospectively collected serum samples from 27 patients. Agglutinating antisperm antibodies, mainly of the IgG class, were detected in seven men (27 per cent), a significantly increased frequency compared to prevalences previously found among blood donors and men from infertile couples. The antibodies developed de novo in four patients (15 per cent). The increased incidence of positive sera and the kinetics of the antibody responses strongly indicate a causal link between acute epididymitis and autoimmunization against spermatozoa. In the majority of the patients the antibody titers were low, being of only theoretical importance in respect to later fertility.

Pneumopericardium after pneumonectomy and lobectomy.

Pneumopericardium is a rare condition, most frequently reported in connection with prolonged artificial ventilation in infants with hyaline membrane disease. No reports of pneumopericardium after pulmonary surgery have been published. Two cases of pneumopericardium are reported, one of tension pneumopericardium after pneumonectomy and artificial ventilation and one that followed radical lobectomy and artificial ventilation. The radiographic findings included pneumopericardium and subcutaneous emphysema and the patient who had had a pneumonectomy had severe symptoms of cardiac tamponade. Prolonged artificial ventilation in patients after pulmonary surgery and in the presence of an intrathoracic air leak may be a hazard. The importance of prompt surgical intervention in cases of tension pneumopericardium is underlined; the treatment of choice is thoracotomy with pericardiotomy.

Pancreatic pseudocysts during first attack of acute pancreatitis.

One hundred and forty-eight patients admitted with their first episode of acute pancreatitis were examined by ultrasonography. During the acute attack 1 or more pseudocysts were found in 19 patients (13%), pancreatic abscess in 2, whereas 127 had a normal or swollen pancreas. Two small cysts resolved spontaneously, eight were cured after ultrasonically guided needle aspiration or catheter drainage, and cystogastrostomy was necessary in four cases. One patient refused treatment. Abscesses requiring surgical drainage developed in four of the patients with pseudocysts. The study showed that pseudocysts may appear as early as within 1 week of the first episode of acute pancreatitis. Some pseudocysts may resolve spontaneously, and ultrasonically guided aspiration or drainage may cure approximately half of the pseudocysts.

Chlamydia trachomatis in acute epididymitis.

The etiology of acute epididymitis was studied in 52 patients. Infection with Chlamydia trachomatis was demonstrated by culture or serology in 13 patients. In men under the age of 25 C. trachomatis was associated with 7 out of 9 cases of epididymitis, in contrast to none of the 19 cases in men above 35. Culture from the urethra is probably sufficient in diagnosing infection with C. trachomatis in patients with acute epididymitis, since only one patient with a negative urethral culture had a chlamydia-positive aspirate from the epididymis. Half of the cases of epididymitis in men above the age of 35 years were associated with urinary tract infection. One patient was infected with N. gonorrhoeae and one had tuberculosis of the epididymis.

What do doctors know about statistics?

A multiple choice test with nine statistical questions was sent to a random sample of Danish doctors to assess their knowledge of elementary statistical expressions (SD, SE, p less than 0.05, p greater than 0.05 and r). One hundred and forty eight (59 per cent) of 250 doctors answered the questions. The test was also completed by 97 participants in postgraduate courses in research methods, mainly junior hospital doctors. The median number of correct answers was 2.4 in the random sample and 4.0 in the other sample of doctors. It is concluded that the statistical knowledge of most doctors is so limited that they cannot be expected to draw the right conclusions from those statistical analyses which are found in papers in medical journals. Sixty-five per cent of the doctors in the random sample stated that it is very important that this problem is raised.
