Programming a predictive rormula for angina and other risk factors in patients with cardiac diseases undergoing noncardiac operations

We programmed a formula which predicts the incidence of either myocardial infarction or cardiac death during the postoperative period. The original formula was proposed by Shah et al, based on their own data and analysis. The program is simple and is written in a language called Quick Basic. The use of this program is also simple. Such a program has improved the use of this analysis substantially. The program has been posted on to a few Computer network services as a free software.(Suwa K, Ogura S: Programming a predictive formula for angina and other risk factors in patients with cardiac diseases undergoing non-cardiac operations. J Anesth 6: 241–242, 1992)     

Dandy-Walker malformation: analysis of 38 cases

Thirty-eight cases of Dandy-Walker malformation (DWM) are presented. A female predominance of 3:1 was found. Thirty-two cases (84%) were diagnosed within the 1st year of life. Of these, 17 cases (44.7%) were diagnosed at birth. Ten (26%) were delivered by cesarean section. Thirteen infants (34%) had a birth weight below 3000 g. Several associated malformations were observed, the most frequent being capillary angioma (6 case); cardiac malformations, ophthalmic anomalies, agenesis of the corpus callosum, malformed limbs, and occipital meningocele were also seen. These observations indicate that DWM represents a disorder of the midline central nervous system indicative of marked genetic and etiologic heterogeneity with the possibility of showing clinical and pathological alterations intra-and extracranially. Macrocephaly was the most frequent physical finding, appearing in 31 cases (82%). Seventeen (44.7%) patients died, 11 before 6 months of age, 3 between 6 and 12 months, and 3 after 1 year. Postmortem studies were performed in 13 patients. Three cases have been lost to follow-up. Mental retardation (IQ below 70) was found in 11 cases (58% of survivors), low intellect (IQ between 70 and 85) in 4, and only 2 patients showed normal intellectual development (IQ more than 85). The high incidence of malformations having several genetic and environmental origins, as well as the high early mortality of patients with DWM, indicate the complexity of this syndrome, which involves the midline developmental field structures. It is not an isolated malformation of the posterior fossa in most cases.     

Cardiac sensitization induced by phenobarbitone and prolonged by CS2

The arrhythmogenic effect of 8 g/kg noradrenaline given i.v. was increased in male rats pretreated 1–2 day s earlier with phenobarbitone and starved from the time of the first phenobarbitone injection (80 mg/kg followed by 50 mg/kg 6 h later). Daily exposure to 4.0 mg/l CS₂ (first exposure 24 h after the first phenobarbitone injection) for 4 h prevented the decline in susceptibility on the 3rd and 4th days after phenobarbitone, when the reaction of unexposed rats to noradrenaline returned to normal.     

Survivin and aven: two distinct antiapoptotic signals in acute leukemias.

BACKGROUND: Antiapoptotic signals are important in the development, progression and prognosis of malignant tumors. The aim of this study was to determine the two distinct antiapoptotic signals-survivin and aven-in acute leukemias and compare them with clinical and hematological findings and response to therapy. Real-time quantitative PCR was used and survivin and aven were detected at the messenger (m)RNA level. PATIENTS AND METHODS: Sixty-five patients with acute leukemia [37 with acute myeloblastic leukemia (AML) and 28 with acute lymphoblastic leukemia (ALL)] were used as the study group and 10 healthy subjects were used as the control group. RESULTS: Survivin was between 0.0 and 0.829 copy number/cell (median 0.0721, mean 0.5424301909 +/- 0.139799488589) and aven was between 0.0 and 0.853 copy number/cell (median 0.0124, mean 0.070335542 +/- 0.1524685709). We found an important association between survivin and aven (P = 0.000). Both survivin and aven were higher in the study group than in the controls (P = 0.001 and 0.035, respectively). When we compared survivin and aven with other clinical and hematological parameters, there was an important association between survivin and extramedullary involvement (P = 0.033), survivin and alkaline phosphatase (P = 0.06), white blood cell (WBC) count and lactate dehydrogenase (LDH) (P = 0.000), WBC count and uric acid (P = 0.074), hemoglobin level and LDH (P = 0.072), LDH and uric acid (P = 0.057), CD7 expression and survivin (P = 0.097), and CD34 expression and aven (P = 0.058). Response to therapy was evaluated according to the survivin and aven levels. Survivin level was lower in refractory patients as compared with complete responders (P = 0.085). Aven level was higher in patients with relapse as compared with non-relapse patients (P = 0.04). There was no important association between survivin or aven and performance status, lymphadenopathy or organomegaly. CONCLUSIONS: Both survivin and aven are important antiapoptotic signals in acute leukemias, and the association between extramedullary involvement, CD7 expression and CD34 expression, which are important poor prognostic indicators in acute leukemias, suggests that survivin and/or aven may be novel prognostic indicators in acute leukemias. Further studies with a higher number of patients will be more informative.     

Primary Mitral Valve Sarcoma in Infancy

Primary cardiac sarcoma is a rare tumor, found especially in children, particularly in the left side of the heart. This report describes a rare case of primary mitral valve sarcoma in a 7-month-old male infant with hemiparesis and heart murmur who underwent mitral valve replacement because of excessive invasion of the mitral valve by the tumor. The patient remains well, free of recurrence and cerebral metastasis, and without adjuvant therapy 18 months after the operation.     

Cardiac tamponade due to systemic lupus erythematosus in a 7-year-old boy with selective IgG subclass deficiency

Systemic lupus erythematosus (SLE) was observed in a 7-year-old boy with IgG₂ and IgG₄ subclass deficiencies who had been treated with immunoglobulin (100–200 mg/kg/4 weeks) since 2 years of age. The mother and the half-brother displayed the same deficiency. Serum IgG mainly consisted of IgG₁ (98.9%) during the acute phase of SLE due to transient IgG₃ deficiency. While he had no common manifestations of SLE such as arthritis or nephropathy, he developed cardiac tamponade due to massive pericardial effusion. Conclusion The clinical features of SLE in the present case such as the development of cardiac tamponade and the absence of renal involvement may result from the markedly imbalanced IgG subclass distribution among auto-antibodies.

Intracranial leiomyosarcoma: A neuro-oncological consequence of acquired immunodeficiency syndrome

We describe a case of glioblastoma treated with chemoradiotherapy that spread to the dura mater with direct invasion of the skull base, protrusion into the homolateral nasal fossa, and penetrated of the frontal sinus, the orbital wall and the ethmoidal sinuses. Only eight cases of glioblastoma showing this development have been described in the literature; one of these, however, had a sarcomatous component which was absent in our case.

Ethical issues in neonatal intensive care and physicians' practices: A European perspective

An international project (EURONIC) was carried out to explore the end-of-life decision-making process in a large, representative sample of neonatal intensive care units (NICUs) in eight western European countries: France, Germany, Great Britain, Italy, Luxembourg, the Netherlands, Spain and Sweden. Structured questionnaires were used to record data on NICU organization and policies, and to survey staff views and practices regarding ethical decision-making. One hundred and twenty-two NICUs were recruited by census or random sampling (response rate 86%); 1235 physicians and 3115 nurses completed the staff questionnaire (response rates 89 and 85%, respectively). This paper focuses on the physicians' answers. In all countries but Italy, most physicians reported having been involved at least once in setting limits to intensive care because of a baby's incurable condition and/or poor neurological prognosis. Adopted strategies varied between countries. Practices such as the continuation of current treatment without intensifying it and the withholding of emergency manoeuvres appeared widespread. In contrast, the frequency of doctors reporting withdrawal of mechanical ventilation was highest in the Netherlands (93%), Sweden (91%) and the Great Britain (88%), intermediate in France and Germany, and lowest in Spain and Italy (34 and 21%, respectively).
Conclusion: Ethically problematic clinical cases are approached differently in the various countries. The findings of this study may provide an opportunity for physicians to review their practices critically, in light of how other colleagues proceed, and foster an open discussion about these difficult issues.
