Suprasellar pituitary adenoma arising from the pars tuberalis: case report

A rare case of suprasellar pituitary adenoma arising from the pars tuberalis in a 53-year-old woman is presented. The tumor was located exclusively above the diaphragma sellae, and no invasion into the sella turcica was noted.     

Beneficial effect of diltiazem on pulmonary hypertension in a patient with Hughes-Stovin's syndrome]

A 54 year-old female who had a history of hemoptysis was admitted to our hospital because of dyspnea on effort. Pulmonary arterial pressure was elevated and pulmonary arteriography showed multiple pulmonary arterial aneurysms and occlusion of the left upper lobe pulmonary artery. Systolic pulmonary arterial pressure was 110 mmHg when measured by continuous wave Doppler echocardiography. From the clinical and angiographical findings, we diagnosed this patient as having Hughes-Stovin's syndrome (forme fruste). 30 mg of diltiazem per day was initially used, and 80 mg was used thereafter. After 2 months follow up of the medication with diltiazem, systolic pulmonary arterial pressure decreased from 110 mmHg to 61 mmHg and clinical symptoms improved dramatically.     

Clinical study of primary carcinoma of the fallopian tube: experience with 14 cases

Between 1950 and 1986, 14 cases of primary carcinoma of the fallopian tube were treated and diagnosed at the Cancer Institute Hospital. These cases constituted 0.13% of the total number of gynecologic malignancies at the hospital during the period. The clinical/pathological findings and prognoses were described. Of the 14 cases, the average age was 56.0 years. The most frequent symptom was atypical genital bleeding, seen in 11 cases (79%). Massive watery discharge was seen in four cases (29%). In preoperative cytologic examination of vaginal smears, six cases (43%) were positive for cancer. All cases underwent operation as therapy. Postoperative irradiation, adjuvant chemotherapy, and/or second-or third- look operation was also used. Histopathologically, all materials were found to be adenocarcinoma. Four cases were well differentiated, seven were moderately differentiated, and three were poorly differentiated. Two patients with stage III and IV cancers died of the disease. Nine patients were still alive at the end of this study. The five-year survival rate was 57% (4/7). In stage I cancers, the five-year survival rate was 80% (4/5). The prognosis of stage I cancer patients was estimated as rather good.     

DNA distribution pattern of the so-called severe dysplasias and small carcinomas of the colon and rectum and its possible significance in the tumor progression

The DNA distribution pattern was determined by cytofluorometry in 25 cases of colorectal small carcinoma and the so-called severe dysplasia. The colorectal carcinoma and "severe dysplasia" consisted of four principal stemlines as to DNA ploidy: diploidy, aneuploidy, and their respective polyploidies. These patterns appeared in various combinations in individual neoplasms. DNA distribution of the severe dysplasia was diploid-predominant (11 cases) or aneuploid-predominant (three cases), usually showing mosaicism in various degrees with respective first order polyploidy. Similar DNA distribution patterns also were found in submucosally invasive small carcinomas. The neoplastic cell populations of a higher polyploidy (second or third order), however, occurred only in the submucosally invasive carcinomas (three cases) regardless of their basic ploidy. The mitotic index tended to be higher in the aneuploid-predominant tumors than in the diploid-predominant tumors. In the current observation, there was no significant correlation between the DNA distribution pattern and histologic type of the "dysplasia" or carcinoma. We found that most of the so-called severe dysplasias of the colon and rectum already gained definitive characteristic of carcinoma in the DNA pattern, i.e., ploidy heterogeneity. Therefore, they can be identified as intramucosal carcinomas, distinct from the normal epithelia and adenomas of the colon and rectum.     

An in vitro evaluation of simplified quantitative diagnostic aids for detection of Candida albicans.

Sensitivities and abilities of quantitative detection for Candida albicans of five simplified diagnostic aids for candidosis or denture stomatitis--Microstix-Candida, Stomastat medium, Mizuno- Takada medium, CA-TG medium, and "milk test"--were examined in vitro, and the characteristics or the indications for clinical use of these summarized.     

Application of visual analogue scale of happiness to elderly Himalayan highlanders]

Visual analogue scale of happiness (VAS-H) was applied to elderly Himalayan highlanders to investigate the influence of life-style and socio-cultural background on subjective happiness. The score of "VAS-H" and neuropsychological function tests in 733 Himalayan highlanders who belonged to 5 separate villages were compared with those in 313 Japanese elderly subjects. The places of study consisted of 4 villages (Khalimabad; K, Gulmit; G, Pasu; P, Shimshal; S) in Hunza area in Pakistan, and Namche Bazar; N in Nepal. Degree of modern civilization was highest in K, followed by N, G, P and lowest was that in S by historical and sociological aspects. The mean VAS-H sore in Himalayan highlanders and the degree of modern civilization in the area was in inverse proportion. Himalayan elderly women showed a significant lower score on VAS-H compared with elderly Himalayan men or elderly Japanese subjects. The VAS-H score in the Japanese elderly correlated significantly with the stability of posture and walk, and that of Himalayan highlanders correlated significantly with manual skill. In conclusion, the life style or socio-cultural background strongly affected subjective happiness in the elderly. The VAS-H was useful in comparing subjective happiness in different cultures.     

Clinical significance of reverse redistribution in exercise thallium-201 SPECT after percutaneous transluminal coronary angioplasty

Clinical significance of reverse redistribution on thallium image was evaluated in 54 patients who had undergone PTCA. Thallium SPECT imaging was performed one week and three to six months after PTCA. Reverse redistribution was detected eight of 54 patients one week after PTCA and five of 38 patients three to six months after PTCA. In the segments with reverse redistribution, reduced regional wall motion and lesser degree of coronary stenosis was common features (p less than 0.05) angiography. In conclusion, reverse redistribution had a tendency to appear in the region with mild myocardial injury and relatively high coronary blood flow after PTCA. But in cases with new occurrence and disappearance of reverse redistribution during follow up period, we can not assess the factors to explain these phenomena. In these segments, "coronary flow reserve", "stunned myocardium", "hibernating myocardium" or other factors may be related.     

Clinical experiences with a new membrane oxygenator with low priming volume (D702 MASTER FLO 51), studies during pulsatile and constant flow perfusion

The newly developed oxygenator "D702" is a compact hollow fiber membrane oxygenator with a priming volume of 170 ml. The maximum flow allowance is 4 liters per/minute. We used this oxygenator in 16 patients (11 infants and children, and 5 adults) undergoing various open heart surgery, and function of this oxygenator was studied. Pulsatile cardiopulmonary bypass was performed in 8 patients and nonpulsatile constant flow perfusion was employed in the remaining 8 patients. Our clinical experience showed excellent maintenance of PaO2 and PaCO2 during both pulsatile and constant flow bypasses. A low pressure drop was encountered across the membrane oxygenator, and therefore, this oxygenator is applicable for pulsatile cardiopulmonary bypass. The D702 is a very useful and applicable for a wide range of patients from infants to adults with a small body structure.
