A new cardiology patient simulator.
We report a new cardiology patient simulator developed through the application of new digital computer technology, capable of playing back selected physical findings (jugular-venous waves, arterial pulses of carotid, brachial, radial and femoral arteries, and cardiac impulses), as well as cardiac sounds, murmurs and respiratory sounds that have been prerecorded from actual patients. The examining physician uses an ordinary type of stethoscope. Four built-in speakers are located in the human-sized mannequin at the classic auscultatory sites (aortic, pulmonic, tricuspid and mitral). This compact and portable educational apparatus should facilitate medical training in the bedside cardiac examination, of physicians, medical students, nurses and paramedics throughout the world.

Peritoneal washing cytology at second-look laparotomy in cisplatin-treated ovarian cancer patients.
The use of peritoneal washing cytology during second-look laparotomy in 58 cisplatin-treated ovarian cancer patients was evaluated. Washing was performed for the 41 patients who showed no gross evidence of persistent disease. Peritoneal washing cytology was positive in 8 of 18 cases with histologically identified residual disease and in 4 of 23 cases without residual disease. However, three of the four cytologically positive patients without other evidence of disease later died of recurrences. The five-year survival rate of the 23 patients who showed no residual carcinomas macroscopically was 60.9%; when their washing cytologies were negative, there was a 73.7% five-year survival rate. These findings indicate that, despite its limitations, a peritoneal washing cytology at the time of second-look laparotomy is important to assess the response to treatment and to evaluate the prognosis of patients with ovarian cancer.

Postoperative changes in vaginal smears after vaginal reconstruction with a free skin graft.
Surgical vaginal reconstruction was performed by a free skin graft in two patients without a vagina. The postoperative changes in vaginal smears collected from the artificial vaginas were observed for about two years. Marked operation-induced inflammatory changes were observed until the second postoperative month. After the third postoperative month, the background became relatively clear. Cyanophilic and eosinophilic superficial cells, intermediate cells and Döderlein bacilli were observed occasionally in addition to keratotic cells. Six to 12 months after surgery, the vaginal smears showed little abnormality, except for the presence of keratotic cells. The changes in the vaginal smears after the third month show that the artificial vaginal epithelium changed cytologically to an almost normal vaginal mucosa that, although not histologically complete, responded to hormones. The presence of Döderlein bacilli suggests that the regional environment of the artificial vagina was almost the same as that of the normal vagina.

Cervicovaginal and endometrial cytology in ovarian cancer.
The clinical significance of cytologic examination was studied in 114 patients with ovarian cancer who had received preoperative cytologic examinations. The overall positive rate of the cytologic examinations was 26.3% (30 of 114): 22 (19.3%) of the 114 cases had positive cervicovaginal smears while 13 of 31 endometrial aspiration smears (41.9%) were positive. The positive rate was not related to the volume of ascites but rather to its presence or absence. Thus, if ascites was observed, the positive rate was about 2.1 times higher than if it was absent. In two of four cases of ovarian cancer with no endometrial invasion but a positive cytologic examination of ascitic fluid, fallopian tube specimens contained cancer cells; this suggests that ovarian cancer cells may reach the cervix and/or vagina by passing through the fallopian tube, particularly if ascites is present. Since cytologic examination, especially of endometrial aspiration smears, shows a high positive rate if ovarian cancer cells are observed in the abdominal cavity, cytology should be used as an important ancillary method for the assessment of ovarian cancer.

Transmission and scanning electron microscopic study of the same cytologic material.
The same cytologic material was successively examined by light microscopy (LM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). After the SEM examination, the specimens were rehydrated for a long period of time to allow the penetration of Epon 812 into the cells. The TEM examination showed the cell organelles to be comparatively well preserved. These consecutively performed LM-SEM-TEM examinations provided useful information on cytologic subjects, especially concerning the origin of the cells.

Cytologic diagnosis of primary tubal cancer.
A study was made of the 128 cases of primary tubal cancer reported to date in Japan, especially of the 61 cases with a preoperative cytologic examination, which was positive for malignancy in 28 cases (45.9%). A positive cytologic diagnosis was made on the cervicovaginal smear in 37.9% of the 58 cases so examined and on the endometrial smear in 80.0% of the 15 cases so examined. Of the 12 cases with positive endocervical smear cytologies, 11 were without endometrial invasion and 4 had no cancer cells in the cervicovaginal smear. Histologic examination of endometrial curettage specimens was positive for cancer in 8 (23.5%) of 34 cases so examined. Endometrial invasion by cancer cells was seen in 11.1% of the surgically extirpated endometrial specimens. The results of this study suggest that cytologic diagnosis is one of the most reliable methods for detecting primary tubal cancer before a surgical operation is undertaken. Its efficacy might be improved by more careful sampling and study in patients suspected of having primary tubal cancer.
