Hereditary spherocytosis (HS) is a condition characterized by jaundice, hepato-splenomegaly tumors, and the presence of spherocytes. It accounts for about 70% of the reported cases of congenital hemolytic anemia in Japan. Many researchers state that this pathologic condition primarily arises from an abnormality of the red blood cell membrane. We have encountered a familiy, all the members (23-year-old daughter, 20-year-old son, 53-year-old-father, and 46-year-old-mother) of which had their cases diagnosed as HS by peripheral blood examination and electron microscopy. Excluding the farher, the peripheral blood examination also revealed anemia in the other family members. Moreover, the common HLA was found in all the members of these two families including the one on the mother's side, but human parvovirus B19 was not detected at all. We are providing the socalledprophylactic visiting care for the two families, while giving them information about HS which is arelatively easily-misunderstood hereditary disease. We did not find any report about married coupleswith hereditary spherocythosis. In this paper, we report our findings so far obtained through visiting care with some bibliographic discussion on HS.

Telomerase has been reported to increase its activity in more than 80% of human pulmonary cancer tissue samples, thus potentially contributing to cancer diagnosis. This led us to try the measurement of telomerase activity in bronchoalveolar lavage fluid in cases clinically suspected to be primary pulmonary cancer. Methodologically, the measurement was made by means of TRAP (telometric repeat amplification protocol) assay, a high-sensitivity assay system using the technique known as polymerase chain reaction (PCR). The resultsshowed that telomerase activity in all the 6 cases, diagnosed as primary lung cancer histologically, was positive. On the other hand, on cytologic examination, 4 out of these 6 cases were positive, and the remaining 2 cases (squamous cell carcinoma and adenocarcinoma) were negative. Histologic examination revealed that of these 4 cases, 2 and 2 were pulmonary cancers and pulmonary tuberculoses, respectively. The above results suggested that examination of telomerase activity in bronchoalveolar lavage fluid may be useful for cancer diagnosis clinically.

During the one-year period from April 1992 through March 1993, we measured 25, 498 blood samples by the use of a sequential multichannel autoanalyzer, which our hospital installed in August 1991. Of the total, 4, 707 samples were thoroughly examined under the microscope. They included those from the patients for which physicians indicated laboratory testing, those samples whose white cell counts were less than 3, 000/μlor more than 10, 000/μl, the cases in which the amount of hemoglobin was less than 10.0g/dl, and the samples which defied blood typing. The result was that three cases of myelodysplastic syndrome were detected, although the autoanalyzer failed to find any abnormalities in these three cases.
Laboratory technicians in hospital are so busy that they hardly have time enough for thoroughgoing examination of hemogram. Nevertheless, the recent experience has brought home to us the importance of a microscopic scrutiny, into hemogram and its application to diagnosis.

With the diagnosis of metastatic tumor of the lung suspected, we had a chance to experience a histopathological case of carcinoma of the uterine cervix (adenoid squamous cell carcinoma), which was thought to coexist with carcinoid tumor. In this paper, we report the results of cytological as well as histological examinations of the case.
The patient was as 43-year-old woman. She visited our hospital, complaining about abnormally prolonged uterine bleeding (metrorrhagia). Cytodiagnosis was performed with a Papanicolaou smear. A microscopic examination revealed squamous cell carcinoma occurring together with adenocarcinoma. A similar finding was obtained by cervical biopsy. Thus, the case was diagnosed as adenoid squamous cell carcinoma.
Then the patient underwent radical hysterectomy and lymphadenectomy, followed by chemotherapy. After leaving the hospital, she was put under doctor-monitored observation. About 4 years after the surgery, a chest x-ray examination found abnormal shadows. For inspection, bronchoscopy was performed. Carcinoid of the lung was diagnosed through histopathological as well as electron microscopic examination of specimens taken from bronchial polyps during bronchoscopy. At the same time a cytologic study was conducted. It also revealed neoplasms strongly suspected of caricinoid tumors. Retrospective studies of cytological and histopathological images of the uterine cervix when the patient first visited us found only adenocarcinoma and squamous cell carcinoma, but no signs of carcinoid tumors. However, the immunohistological staining of NSE and chromoganins A, both neuroendocrine markers, showed positive findings in some adenocarcinomatous parts of the tissues of the unterine cervix. Therefore, we considered that the cervical cancer is compounded of adenoid squamous cell carcinomas and tumors having properties of neuroendocrine cells.
From this, we concluded that it is necessary to take into account a differential diagnosis of neuroendocrine tumors including carcinoid of the uterine cervix when less differentiated adenocarcinoma and squamous cell carcinoma are suspected in histological and cytological examinations. Furthermore, we thought it important to make a definite diagnosis after meticulous examinations by immunohistological staining and electron microscopy.

With household digital compact wrist blood pressure monitors, blood pressure was measured in hemiplegic patients who were receiving kinesitherapy.
During the training program routinely worked out by physical therapists, most patients had shown elevated levels of both systolic and diastolic blood pressure. There were some patients whose blood pressure went up so high as to call doctors' attention.
As changes in blood pressure are affected by various factors, we cannot say at once that doing exercise alone adds to blood pressure. Nonetheless, by using a household blood pressure monitor, it would be easy to know the extent to which blood pressure rises in accordance with the amount of exercise, so that it would be possible to make patients and their family aware of the importance of blood pressure readings. We thought it possible to obtain an index of the amount of exercise at home.

BACKGROUND:
Ibaraki's Amabie-chan is a COVID-19 infection control system unique to Ibaraki prefecture, Japan. It requires residents to register each time they visit events, commercial facilities, and restaurants. The number of registrations has been limited, and its function alerting about people positive for COVID-19 infection seems not to be working. Nevertheless, registration with the system might have some impact on the user's behavior. In the current preliminary survey, the possible impact of Ibaraki's Amabie-chan on infection prevention behavior and fear of COVID-19 was investigated.
METHODS:
A cross-sectional, web-based, anonymous, and self-administered survey was conducted at two workplaces in Tsukuba Science City, Ibaraki, Japan. The first survey was conducted at one of the workplaces in November 2020, and the second survey, at the other workplace in February 2021. Variables of interest were sex, age group, marital status, employment status, Ibaraki's Amabie-chan use, COVID-19 Contact-Confirming Application use, ten items of infection prevention behaviors, and fear of COVID-19. Hierarchical linear regression analysis was performed.
RESULTS:
In both surveys, use of Ibaraki's Amabie-chan was significantly associated with COCOA use and with "physical condition management such as body temperature measurement." No association was found with other infection prevention behaviors or with fear of COVID-19.
CONCLUSIONS
Our findings did not provide sufficient evidence for the effectiveness of Ibaraki's Amabie-chan in regard to users' infection control behavior. Further detailed study is needed to investigate the effectiveness in terms of infection prevention and the cost-effectiveness of Ibaraki's Amabie-chan.
