CD14 and TNfa promoter polymorphisms in patients with acute arthritis. Special reference to development of chronic spondyloarthropathy

OBJECTIVE: To examine CD14 and TNFalpha gene polymorphisms in early arthritis in relation to clinical outcome. METHODS: We studied 141 Caucasians who had had early arthritis 10 to 38 years earlier. We analysed CD14 (-159) and TNFalpha (-238, -308, -376) polymorphisms using a novel cycle minisequencing method. DNA pools from 370 Caucasian blood donors served as controls. RESULTS: CD14 (-159)C-->T allele frequencies were comparable among patients and controls (39% vs 40%). Fifty men and 42 women had recovered while 24 men and six women had chronic spondyloarthropathy (SpA). Mutant T allele frequency was higher in the chronic SpA group than in the recovered group in women (75% vs 32%, relative risk 1.3, 95% confidence limit 1.1 to 1.6, P = 0.011), but not in men (38% vs 44%). All female patients with chronic SpA had CD14 (-159)T allele and none had a possibly protective TNFalpha (-308)G-->A allele. CONCLUSIONS: Possession of CD14 (-159)T allele does not increase risk of ReA but may increase susceptibility of female patients to development of chronic SpA.     

Apolipoprotein E alleles in women with intrahepatic cholestasis of pregnancy

OBJECTIVE: To investigate the frequency of apolipoprotein E (apoE) alleles among women with intrahepatic cholestasis of pregnancy. METHODS: The presence of the three most common apoE alleles (epsilon2, epsilon3, epsilon4) was determined by polymerase chain reaction-restriction fragment length polymorphism in two groups of women: healthy pregnant women (n = 47) and pregnant women with a diagnosis of intrahepatic cholestasis of pregnancy (n = 44). In addition, the frequencies of the alleles in the general population in our area are presented for comparison. RESULTS: The frequency of the apo epsilon4 allele was 21.6% among women with intrahepatic cholestasis and it was 16.0% among healthy pregnant women (Fisher exact test; P= 0.216), which is close to the rate in the general population in our area (19%). None of the apoE genotypes was significantly over-represented, and homozygous genotype epsilon4 was not associated with more severe clinical disease than other genotypes. CONCLUSION: The observed profiles of allele and genotype frequencies confirm the equilibrium state between apoE polymorphism and obstetric cholestasis and suggest that apoE does not play a major role in the development of intrahepatic cholestasis of pregnancy.     

Acute anemia in high digestive hemorrhage. Margins of security for their handling without transfusion of red globules

Red cells transfusion in the patient with acute hemorrhage, must be evaluated in a risk/benefit rate context. The present tendencies appoint that the use of the hematocrit "magic" number is unsafe and uncertain to decide a red cell transfusion. We have conducted a prospective randomized and controlled trial in 60 patients with acute digestive hemorrhage without haemodynamic failure. We realized two groups: 1) control group: the target of transfusion in these patients was the hematocrit value of > or = 28%. 2) treatment group: these patients were supported with normovolemic haemodilution with crystalloid solutions until a hematocrit value of 21%. All patients have endoscopic diagnosis and they went evaluated across the study with clinic and laboratory controls. Both groups were significative differences in the hematocrit value. We did not see differences between the groups in the hospital stay neither the rate of organs failure. We find difference between the groups in the amount of red cell units (0.61 +/- 0.87 vs. 2.14 +/- 1.10; treatment and control respectively, P < 0.001). The APACHE score was greater in the treatment group. This supports that the oldest patients, who probably have least physiologic reserve, could be treated without complications.

Respiratory sinus arrhythmia as a predictor of sudden cardiac death after myocardial infarction

Background. Measurement of high-frequency (HF) spectral power of heart rate (HR) variability has not been able to identify the patients at risk of sudden cardiac death (SCD) despite the experimental evidence of protective role of vagal activity for fatal arrhythmias.

Aim. We developed a novel respiratory sinus arrhythmia (RSA) analysis method and tested its ability to predict SCD after an acute myocardial infarction.

Method. The RSA analysis method was developed in 13 subjects from simultaneous recordings of respiration and R-R intervals. An adaptive threshold was computed based on the zero-phase forward and reverse digital filtering in the analysis of RSA. With this method, only respiration-related R-R interval fluctuations are included. The prognostic power of RSA, analyzed from 24-hour electrocardiographic recordings, was subsequently assessed in a large postinfarction population including 1631 patients with mean follow-up of 40±17 months.

Results. Depressed RSA was a strong predictor of SCD (hazard ratio 7.4; 95% CI 3.6–15.1; P <0.0001) but only a weak predictor of non-SCD. The RSA index remained an independent predictor of SCD after adjustments for ejection fraction and other clinical risk variables (RR 4.7; 95% CI 2.28–9.85).

Conclusions. Reduced respiratory-related HR dynamics, detected by RSA index, are a specific marker of an increased risk of SCD among postinfarction patients.     

Effect of intrathecal fibrinolytic therapy on clot lysis and vasospasm in patients with aneurysmal subarachnoid hemorrhage

A prospective series of 30 patients with a single, angiographically verified aneurysmal subarachnoid hemorrhage (SAH) was studied for the effect of intrathecal thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA) on outcome, angiographic vasospasm, and computerized tomography (CT) findings after surgery. The patients included fulfilled the following criteria: operation was performed by Day 3 after the hemorrhage, CT showed only blood in the basal cisterns, and the patient had a single aneurysm or multiple aneurysms that could be treated surgically at the same operation. The patients were divided into groups of 10, with patients receiving 3, 10, or 13 mg of rt-PA in a single intracisternal injection at the end of the operation. There were no differences between the treatment groups in overall outcome. One patient from the 3-mg rt-PA group developed a postoperative intracerebral hemorrhage, and one patient from the 10-mg rt-PA group had a postoperative epidural hematoma. There was one death in the 13-mg rt-PA group that was caused by inclusion of a segment of pericallosal artery in the clip. In all treatment groups a reduction was observed in the amount of blood seen on the postoperative CT scans compared to the preoperative CT scans. The reduction in SAH grade between the 10-mg and 13-mg rt-PA groups was significant (p less than 0.05). The difference in the severity of angiographic vasospasm between the 3-mg and 13-mg rt-PA groups was also significant (p less than 0.05).     

Cosmetic results after wire-guided biopsy of benign breast lesions

Background: There are surprisingly few reports about the cosmetic results of wire-guided biopsy of benign breast lesions as opposed to breast-conserving surgery and irradiation of early breast cancer (BCT).

Study Design: Twenty potential perioperative risk factors for adverse cosmetic results after wire-guided breast biopsy were prospectively evaluated in 101 patients undergoing the first single biopsy after suspicion of a malignant lesion that subsequently proved to be benign. The overall cosmetic result was evaluated by using 6 specific cosmetic indices individually scored 6 months after the breast biopsy.

Results: The overall cosmesis was excellent, good, fair, or poor in 48.5%, 26.7%, 12.9%, and 11.9% of cases, respectively. The corresponding figures according to appraisal by the patients were 22.8%, 58.4%, 17.8%, and 1.0%, respectively. Unsatisfactory (fair or poor) overall cosmetic results were related to excisions extending down to the fascia (p = 0.001) and postoperative complications (p = 0.018) in multivariate analysis. Notably, specimen volume had no significant impact on overall cosmesis, as opposed to cosmesis after BCT.

Conclusions: Cosmetic outcomes after wire-guided biopsy of benign breast lesions were excellent or good in at least 75% of cases. Excisions extending down to the pectoralis fascia and complications were associated with poor aesthetic outcomes.     

Minimizing systemic absorption of topically administered ophthalmic drugs

Due to absorption several ocularly applied medications give rise to systemic side-effects. The problem of systemic drug absorption should be taken into account in designing ocular drug and dosage forms so that oculospecificity of the medications is optimized. In this review we summarize the current knowledge about the systemic absorption of ocularly applied topical drugs. Special emphasis is directed to the methods that can be used to minimize systemic absorption and increase the oculospecificity of drugs, e.g., reducing volume and increasing viscosity of eyedrops, controlling drug release from depot preparations, prodrug-derivatization, and addition of vasoconstrictive agents.     

Mothers' perceptions of and feelings towards their babies' crying

The frequency and type of crying and the parents' perceptions of it were evaluated in 281 Finnish infants underthe age of 1 year. Not many mothers [14#pc] claimed that their babies cried often or very often. The infants less than three months old cried significantly more in the evening than the older ones. Most mothers [94#pc] reported that the crying aroused feelings of tenderness, but 4#pc found it irritating. The most common response to the cry [97#pc] was to pick the baby up. Additional help was wanted by 49 mothers because of their babies' disturbing crying spells. These mothers reorted that their infants cried more and they stated that the cry made them feel more irritated and more often gave them a feeling of failure than the mothers not in need of help. The majority of these mothers would have been glad to help, including advice, whent the infants were under 3 months of age.     

Traumatic fistula between the left anterior descending coronary artery and a left ventricular pseudoaneurysm

A 44-year-old man presented with a fistula of the left anterior descending (LAD) coronary artery to a left ventricular pseudoaneurysm 6 months after a stab injury in the left anterior chest. The color Doppler echocardiography suggested, and angiography confirmed, the diagnosis and the lesion was treated successfully. Traumatic coronary artery fistulas are rare complications, and color Doppler echocardiography proved useful for the diagnosis. Received: 0/00/00/Accepted: 0/00/00
