INFORMATION on the "natural history" of congenital cardiac malformations is difficult to obtain and may have very little meaning for the statistician. One is aware that the facts obtained may yield a profile only of those patients with heart malformations who have signs and symptoms significant enough to bring them to a cardiac center. The others, either not sick enough to come to a center, or too sick and even dying before they can be brought to the specialist, or living too far from the medical center, therefore, will not be included in any survey. The only way the entire congenital heart disease population may be caught in the net of the investigator is by following up carefully a large group of newborns. Though information gathered may not be statistically significant it is none the less important as a frame of reference in making recommendations to patients and their families. Also it is of necessary historical import that we document the course of patients with malformations as yet unaltered by the hand of the surgeons. The effect of surgery on patients with certain malformations is far reaching and changes the course of their natural history. Another reason why we should try to find out what happens without operation to certain patients is that there will be a tremendous advance in cardiovascular surgical techniques for many lesions yet in the future. Nobody questions the fact that cardiac surgery, in many, if not most, areas will be better tomorrow than it is today. The notable exceptions to improvement of surgical techniques include repair of patent ductus arteriosus, coarctation of the aorta, secundum atrial septal defect, and pulmonic stenosis.

Poor Weight Gain

A previously well, nine-month-old, Canadian-born, Caucasian infant presented with one month history of cough, irritability, and poor weight gain. Her past medical history was significant for open-heart surgery at age four months, with repair of a ventricular septal defect, closure of an atrial septal defect, and ligation of patent ductus arteriosus. There were no operative complications. Her development was normal for age. She had received her routine immunizations.There was no known infectious diseases contact or exposure to farm animals.

Control Study

The Baltimore-Washington Infant Study is an ongoing case-control study of congenital cardiovascular malformations in infants in whom the clinical diagnoses have been confirmed by echocardiography, catheterization, surgery, or autopsy. An increase in the prevalence of ventricular septal defects was detected in 1,494 infants with congenital cardiovascular malformations between 1981 and 1984. The prevalence of congenital cardiovascular malformations increased from 3.6 to 4.5 per 1,000 live births (P<.025) and the prevalence of ventricular septal defect increased from 1.0 to 1.6 per 1,000 live births (P< .001). The increase in ventricular septal defects accounted for the total increase in congenital cardiovascular malformations. The prevalence of isolated ventricular septal defect increased from 0.67 to 1.17 per 1,000 live births (P<.001). The prevalence of ventricular septal defect with associated coarctation of the aorta, patent ductus arteriosus, atrial septal defect, and pulmonic stenosis did not change. The prevalence of ventricular septal defect diagnosed by catheterization, surgery, and autopsy did not change; however, defects diagnosed by echocardiography increased from 0.30 to 0.70 per 1,000 live births (P<.001). It is concluded that the reported increase in prevalence of ventricular septal defect is due to improved detection of small, isolated ventricular septal defects and that there is no evidence of an "epidemic."

Abstract Seven historical bat specimens of four species (Rhinolophus ferrumequinum, R. mehelyi, Taphozous nudiventris, Myotis myotis), attributed to originate from the territory of the present-day Lebanon, are deposited and documented in the modern database of the mammal collection of the Natural History Museum, Vienna, Austria (Naturhistorisches Museum Wien). Two of these species (R. mehelyi, T. nudiventris) have never been reported for Lebanon in the existing literature and recent surveys have also failed to find them in this country. Since these bats were collected in the period 1824–1885, the history of the all respective specimens was evaluated in detail. The revision brought rather unexpected results. Only one specimen (R. ferrumequinum) was found to come (most probably) from Lebanon, being collected by W. Hemprich and Ch. Ehrenberg in 1824. In the remaining six specimens, the origin could not be defined, thus rendering the statement that they were collected in Lebanon insecure. This case demonstrates that careful checks of modern interpretations of historical records are necessary when examining past distributions of organisms.

The paper presents the results of a prospective trial to examine the natural history of early reflex sympathetic dystrophy (RSD). Thirty patients with post-traumatic RSD of the hand were observed without treatment. They were reassessed 1, 2 and 6 months after diagnosis with a final assessment at 10 to 18 months (average 13 months). Twenty-seven patients completed the study. Three were withdrawn during the study because of persistence of signs and symptoms of RSD and were given further treatment. Of the 27 patients who completed the study, only one showed sufficient features of the condition to warrant the diagnosis of mild RSD. In the remaining 26, most features of RSD had resolved spontaneously. Pain and swelling disappeared more quickly than other features of RSD. Although the signs and symptoms of RSD had largely gone at 13 months, the hands were still functionally impaired because of weaker grip strength.
