Thirty members with typical hereditary spherocytosis (HS) and over 90 apparently unaffected members belonging to 12 families have been studied. Splenectomy has been performed on 22 HS patients. Of nine HS individuals, who had not undergone surgical treatment in 1957, four suffered from temporary severe anaemia, presumably due to aplastic crisis associated with influenza. One of them died, a male 18 years of age. Pedigree studies on one of the families indicate that the HS gene or genes have been transmitted through six generations over the past 200 years. Marked deficiency in the number of affected compared with the apparently unaffected members in the HS families is present. The most striking example of uneven genetic ratio is a sibship of 15 members investigated haematologically, with one suffering from typical HS. Much reduced penetration of the HS gene or the presence of the socalled "mild form" is upheld as the main explanation for the unevenness in the genetic ratio. However, families are also present in which abortions and death at an early age indicated that selection against the affected could also disturb the genetic ratio in HS families.

Arteritis of the aged (giant cell arteritis) masquerades as a degenerative, infectious, neoplastic or even functional disorder in the elderly. In the absence of obliterative vascular changes, the diagnosis is often overlooked when too rigid diagnostic criteria are employed. Four elderly women presented with fever of unexplained origin as the initial manifestation of this disease. The temporal arteries were conspicuously normal in all four, and other traditional clinical clues, such as visual disturbances, headache or manifestations of polymyalgia rheumatica were likewise infrequent of entirely absent. Influenza immunization and uncomplicated rectal surgery preceded the onset of illness in two. Anemia and an increased erythrocyte sedimentation rate are important diagnostic features, particularly in the face of spontaneous clinical improvement accompanied by defervescence and disappearance of nonspecific liver dysfunction. Occult intestinal perforation complicated steroid therapy in one case. Significant and sometimes hectic fever may be a common pattern for this arteritis in its earliest stages, when palpably abnormal temporal arteries, obliterative vascular changes and other traditional diagnostic clues are more likely to be absent.

Interleukin-2 (IL-2) is increasingly used to treat patients with cancers refractory to conventional treatment. Flu-like syndromes are extremely frequent but usually mild. A variety of skin complications (mostly erythema and mucositis) have been reported. Life-threatening skin reactions have also been described. Acute reactivation of psoriasis can also occur. Immediate hypersensitivity reactions have so far not been described, but IL-2 treatment has been shown to predispose to acute hypersensitivity reactions to iodine-containing contrast media. Hypothyroidism is the major endocrine complication and antithyroid antibodies have been detected in approximately 50% of patients. Neurological and psychiatric disturbances with moderate or severe mental status changes are common and sometimes treatment-limiting. The occurrence of peritumoural oedema in patients with brain metastases can also be a major practical problem. Musculoskeletal disorders are transient and resolve spontaneously. The vascular leak syndrome is the most frequent and severe complication of IL-2 of which weight gain, generalised oedema, hypotension and impaired renal function are the main features. Even though a damaging effect on vascular endothelium cells by various cytokines released by activated lymphoid cells or mediated by non-lymphocyte-dependent factors has been proposed to be involved, the mechanism remains unclear. Other cardiovascular injuries, possibly life-threatening, including myocarditis, angina pectoris and myocardial infarction, can occur during the first days of treatment. Supraventricular arrhythmias are the most common rhythmic disorder. Decreases in myocardial contractility and haemodynamic pattern similar to those of septic shock have been encountered in most cases. Acute renal dysfunction is common but resolves with symptomatic management. Intrahepatic cholestasis with hyperbilirubinaemia is observed in most patients but permanent liver damage has not been described. Several cases of pancreatitis have been reported. Anaemia, thrombocytopenia, lymphocytopenia and eosinophilia are frequent and occur in most if not all patients. Some data suggest a high incidence of infectious complications, particularly in patients with surgically tunnelled catheters, but marked flu-like syndromes may be confounding. Finally, death directly related to IL-2 treatment has been noted in less than 1% of all patients. Investigations are under way to minimise IL-2 toxicity with varying dose regimens and combined treatments.

Factors associated with mortality were examined for 27,370 hip fracture patients aged 65 years or older in Maryland hospitals, using discharge data for 1979-1988. Variables of interest included sociodemography, principal medical and injury diagnoses, E-code, year, disposition, and hospital. For both white males and white females, the hip fracture rate doubled with each 5-year increment in age. The overall proportion who died during hospitalization was 4.9% (n = 1,339). After multivariate adjustment, there remained a substantially increased risk of death for males. The relative odds (RO) of dying for males versus females were 1.6. Other factors associated with high relative odds of dying during hospitalization included the diagnosis of septicemia (RO = 12.3), pneumonia/influenza (RO = 4.9), and digestive system disorder (RO = 3.6). The RO of dying doubled in the presence of cardiac, neoplastic, or cerebrovascular disease. Patients with diagnoses of nervous system or mental disorder, hypertension, anemia, musculoskeletal system disease, or urinary tract infection were at decreased risk of dying. Results of the study suggest that the prevention or early diagnosis and treatment of serious infections in the elderly patient with a hip fracture remain an important challenge to clinicians.

Twenty-two evaluable patients with advanced adenocarcinoma of the pancreas, but without prior chemotherapy or immunotherapy, received recombinant tumor necrosis factor (rTNF). rTNF was given as an intravenous infusion over 30 min daily x 5, every 14 days, at a starting dose of 150 micrograms/m2/day. Toxicities included fevers/rigors, nausea/vomiting/anorexia, flu-like symptoms, hypotension, hyperglycemia, anemia, coagulopathy, hepatotoxicity, and hypertriglyceridemia. Laboratory evidence of disseminated intravascular coagulopathy occurred in 11 patients, with only 3 of these patients having clinical manifestations. Two patients suffered from pulmonary emboli. The high incidence of coagulopathy was felt to be, at least in part, disease related. No objective responses were observed with a 95% confidence interval of 0-15%.

Fifty evaluable patients with advanced colorectal cancer, but without prior chemotherapy or immunotherapy, were randomized to one of two schedules of recombinant gamma-interferon (rGIFN). Twenty-four evaluable patients received rGIFN as a 2-h intravenous infusion daily x 5 every other week at a starting dose of 4.0 x 10(6) IU/m2/day (arm I). Twenty-six evaluable patients received rGIFN as a 24-h continuous intravenous infusion daily x 5 every month at a starting dose of 2.6 x 10(6) IU/m2/day (arm II). Toxicities on both schedules included flu-like symptoms, fevers/rigors, nausea/vomiting, hypotension, leukopenia, hepatotoxicity, nephrotoxicity, diarrhea, anemia, confusion, and ileus. Toxicity appeared to be more severe on arm I. No antitumor responses were observed, with 95% confidence intervals of 0 to 14% for arm I and 0 to 13% for arm II.

To evaluate the clinical efficacy of recombinant human erythropoietin (EPO) and its influencing factors in the treatment of anemia in hemodialysis (HD) patients, 17 chronic stable HD patients (10 males, 7 females; mean age: 46.0 +/- 2.6 years) with severe anemia were enrolled in this study. The study period (ranging from 5 to 11 months) was divided into the initial 12 weeks of correction phase and the subsequent maintenance phase. EPO, 1500 U initially, was administered intravenously twice weekly (BIW group, n = 10) or thrice weekly (TIW group, n = 7) at the end of each HD. Dose was doubled every 4 weeks until up to a maximum dose of 6000 U if increment of hematocrit (Hct) was less than 3%. At the end of correction phase, anemia was markedly improved. Hct and hemoglobin (Hb) increased from 19.3 +/- 0.8 to 28.7 +/- 1.1% and from 6.5 +/- 0.3 to 9.6 +/- 0.4 g/dl, respectively. Fifteen patients (88%) reached to the target Hct of 30% at 13.7 +/- 1.2 weeks. At the end of study, Hct and Hb was maintained at 29.1 +/- 0.7% and 9.6 +/- 0.3 g/dl, respectively. Requirement of EPO dose to reach the target and maintain the stable Hct (greater than or equal to 28%) was 99 +/- 14 and 62 +/- 11 U/kg/week, respectively. Laboratory parameters showed that serum iron, transferrin saturation, sugar and triglyceride decreased significantly and uric acid and aluminum (Al) increased significantly. There was no significant change in predialysis blood pressure, body weight, cardiac ratio, and ECG. Quality of life was markedly improved with the better subjective feelings, physical activity and Karnorfsky index. Common adverse effects included exacerbated hypertension (23%), hyperphosphatemia (18%), hyperkalemia (18%), and flu-like syndrome (12%). All of them could be managed by medical and dialysis treatment. Investigation of influencing factors on response to EPO suggests that 1) TIW group had a better response than BIW group 2) Response was better in patients with more adequate iron status and less severe Al burden. 3) Time to target Hct correlated approximately with basal serum Al levels but did not correlate with basal serum parathyroid hormone levels. In conclusion, low dose of EPO therapy corrects anemia effectively with minimal adverse effects in HD patients. Dosing regimen, iron status, and serum Al will influence the response to EPO.

This study was carried out to assess the problems with the pregnant women, and check out the risk-factors in the high-risk pregnancies, using a simplified antepartum risk-scoring system, which was revised from Edwards' scoring system to be suitable for Korean situation. This instrument was included 4 categories, demographic, obstetric, medical and miscellaneous factors. This survey was based on the 1300 pregnant women who were admitted, from Jan. 1, 1988, to May 31, 1990, Chung Ang Medical Center. Data were collected from June 25, 1990 to July 7, 1990. Data was analyzed by x2-test, F-test, Pearsons correction, using statistical package SAS in NAS computer system, KIST. The results of the study were as follows; 1. 1313 infants were deliveried of these 560 infants (42.7%) were born to mothers with risk-scores greater than 7, and 753 infants (57.3%) were born to mothers risk-scores less than 7. 2. Maternal age, parity, education level, of the demographic factors were significant relation statistically to identify the high risk pregnancies (X2 = 20.88, 42.87, 15.60 P less than 0.01). 3. C-section, post term, incompetent cervix, uterine anomaly, polyhydramnios, congenital anomaly, sensitized RH negative, abortion, preeclampsia, excessive size infant, premature, low birth weight infant, abnormal presentation, perinatal loss, multiple pregnancy, of the obstetric factors were significant relation statistically to identify the high risk-pregnancies. (chi 2 = 175.96, 87.5, 16.28, 21.78, 9.46, 8.10, 6.75, 22.9, 64.84, 6.93, 361.43, 185.55, 78.65, 45.52, P less than 0.01). 4. Abnormal nutrition, anemia, UTI, other medical condition (pulmonary disease, severe influenza), heart disease, V.D., of the miscellaneous and medical factors, were significant relation statistically to identify the high risk-pregnancies. 5. Premature, low birth weight infant, contracted pelvis, abnormal presentation, of the risk factors were significantly related with Apgar score at 1 & 5 minute after birth and neonatal body weight. 6. Apgar score at 1 & 5 minute after birth and neonatal body weight were significantly negative correlated with risk-score. 7. There were statistically significant difference between risk-score and Apgar score at 1 & 5 minute after birth, 3 group (0-3, 4-6, above 7), and neonatal body weight, 2 group (below 2.5 kg, the other group) (F = 104.65, 96.61, 284.92, P less than 0.01). 8. Apgar score at 1 & 5 minute after birth (below 7), and neonatal body weight (below 2.5 kg), were significant relation statistically with risk score. (chi 2 = 65.99, 60.88, 177.07, P less than 0.01) were 60.8%, 60%.(ABSTRACT TRUNCATED AT 400 WORDS)
