Translumbar catheter redirection using a tip-deflector technique

A new technique is described for reversing the direction of the catheter tip during translumbar aortography, without the need for partial withdrawal of the catheter from the aortic lumen. The method ensures optimal delivery of contrast medium at the desired level, while avoiding the risk of retroperitoneal bleeding or dislodgement during catheter manipulation.     

A systematic review of the effectiveness of ofloxaxin otic solution for the treatment of suppurative otitis media

The objectives of the study were to determine the effectiveness and incidence of adverse events of ofloxacin otic solution for suppurative otitis media compared with other treatments. All randomized controlled trials and nonrandomized comparative clinical trials published from 1966 to 2000 using ofloxacin otic solution as one of the interventions were reviewed and data were extracted and analyzed. Eleven clinical trials (9 randomized and 2 nonrandomized) enrolling 1,484 adults and children were finally included in the analysis. Five studies employed clear concealment procedure in the allocation of treatment whereas evaluation of outcome was at least single-blinded in 6 trials. The probability of overall cure rate was higher with 0.3% ofloxacin otic solution than with other topical or systemic antibiotics in 9 of the studies analyzed (OR = 2.67; 95% CI = 2.04, 3.50). Resolution of secondary outcome parameters evaluated at least 1 week after treatment was higher with 0.3% ofloxacin otic solution: resolution of otalgia (4 trials; OR = 2.41; 95% CI = 1.2, 4.82); resolution of otorrhea (11 trials; OR = 2.78; 95% CI = 2.12, 3.65), and bacterial eradication rate (6 trials; OR = 3.86; 95% CI = 2.54, 5.87). A subgroup analysis of 4 studies comparing ofloxacin otic solution with antibiotic- and steroid-containing otic solution showed a higher cure rate for ofloxacin otic solution (OR = 2.73; 95% CI = 1.52, 4.90). Another subgroup analysis on 3 studies comparing ofloxacin otic solution with oral systemic antibiotics showed higher resolution of otorrhea with ofloxacin otic solution (OR = 2.78; 95% CI = 2.12, 3.65). Of 4 studies with data on adverse events, the probability of adverse events was lower with ofloxacin otic solution than with other topical antibiotics (OR = 0.28; 95% CI = 0.19, 0.42). Subgroup analysis showed that 0.3% ofloxacin otic solution showed better results in terms of overall cure rate, resolution of otorrhea, otalgia, bacterial eradication rate and incidence of adverse events. Whether due to chronic suppurative otitis media (CSOM) or draining tympanostomy tube, the overall cure rate (CSOM OR = 4.86; with tympanostomy tube OR = 2.13) and resolution of otorrhea (CSOM OR = 4.42; with tympanostomy tube OR = 1.66) were likewise in favor of 0.3% ofloxacin otic solution. The studies included in this meta-analysis showed generally homogenous results in all clinical and laboratory outcomes analyzed, except for the evaluation of adverse events. The authors conclude that 0.3% ofloxacin otic solution is better than other otic antibiotic drops and other oral antibiotics in terms of overall cure rate and resolution of secondary outcome parameters. Estimates on the beneficial effects of ofloxacin otic solution are limited to the period of study included in this review.     

Intestinal tissue oxygenation and tumor necrosis factor-alpha release during systemic blood flow changes in pigs with left ventricular assist devices

We previously demonstrated that tumor necrosis factor-alpha (TNF-alpha) increased following a reduction in systemic blood flow to 60% or less of the original cardiac output using a left ventricular assist device (LVAD). The aim of this study was to investigate the effect of reducing systemic blood flow on tissue oxygenation in the gastrointestinal tract (GIT) and the consequences of this on TNF-alpha release. LVADs were implanted in 9 pigs. The aorta was clamped, and thus the LVAD flow represented the entire systemic blood flow. Plasma TNF-alpha of the superior mesenteric vein was measured at baseline and during systemic blood flow changes. Simultaneously, pH, lactate, oxygen delivery index (DO(2)I), oxygen consumption index (VO(2)I), and oxygen extraction (O(2)ER) in the GIT were measured. The pH decreased and the lactate level increased significantly (p < 0.05) at a systemic blood flow of 50% or less. The VO(2)I was positively correlated with DO(2)I. The O(2)ER increased significantly (p < 0.05) with reductions in systemic blood flow to 30% or less. There was a significant (p < 0.01) correlation between TNF-alpha and O(2)ER at levels higher than 55%. These data demonstrate that the GIT oxygenation is inadequate with a reduction in systemic blood flow to 50% and that GIT oxygenation becomes critical at a reduction of 30%. During LVAD weaning, careful attention must be given to the GIT. The pH and lactate may be good markers of the adequacy of tissue oxygenation in the GIT.     

Diagnostic value of a psychological test in cases of suspected child abuse

The use of the Bene-Anthony Family Relations Test is described and illustrated by three examples of child abuse. This test should be considered in the investigation of definite or suspected cases of abuse and as part of the preparation of court evidence.     

Variations in long- and middle-wavelength-sensitive opsin gene loci in crab-eating monkeys.

We analyzed variations in long (L)- and middle (M)-wavelength-sensitive opsin gene loci in crab-eating monkeys. Unlike humans, most monkeys have a single L and a single M gene. Two variant genotypes, one with only one opsin gene (dichromatic) and one with tandemly arrayed multiple genes, were also found in the monkeys. However, the frequency of the former was 0.47%, and that of the latter was 5% in the monkeys, while 2% and 66%, respectively, in Caucasian males. The two variants were found only in Java Island, Indonesia, and South Thailand, respectively. The data suggest that the frequency of each genotype is different among Old World primates.     

Asymmetrical pulmonary changes in premature infants with surgical closure of a persistent ductus arteriosus

The chest radiographs of 57 premature infants admitted consecutively with hyaline membrane disease and receiving respirator therapy were reviewed, comparing right and left pulmonary abnormalities. Fifteen infants (Group I) did not develop a persistent ductus arteriosus (PDA). Forty-two infants developed a PDA, which was successfully treated with indomethacin in 17 infants (Group II), while in 25 infants (Group III) the ductus was closed surgically. Analysis of the three groups showed that infants who had undergone surgical closure of their PDA developed significantly more asymmetrical broncho-pulmonary damage. Statistically significant fewer radiological findings of broncho-pulmonary damage were found on the left side in comparison with the right side in the group treated surgically.     

Public health the leading force of the Indonesian response to the HIV/AIDS crisis among people who inject drugs

Issue  

Indonesia has an explosive HIV/AIDS epidemic starting from the beginning of this century, and it is in process to build its response. Reported AIDS cases doubled from 2003 – 2004, and approximately 54% of these cases are in people who inject drugs.
