The authors are responsible for their accuracy and they should follow the format and style requested by the journal where they are submitting their paper. Revista Médica de Chile adheres to the "Uniform Requirements" established by the Vancouver Group of Medical Editors. Equally important is a correct choice of references, including those original articles strictly connected to the content of the manuscript. The number of citations usually vary according to the specific character of the study: research article, or case reports, review article, etc. Common mistakes are due to an excessive number of repetitive or irrelevant citations, or the omission of important articles sometimes not found in bibliographic indexes, or an erroneous claim of priority in reporting an observation. Finally, in developing countries the authors should include previous reports appeared in their own local journals, therefore improving their opportunities of achieving international visibility.

Multiple organic dysfunction can be assessed using severity scores. Aim: To relate cytokine kinetics with a multiple organic dysfunction score during sepsis. Material and methods: Tumor necrosis factor a (TNFa) and interleukin 6 (IL6) kinetics were studied in 25 patients with severe sepsis with less than 48 h of evolution and interleukin 1ß (ILß) kinetics was studied in 13 patients. Measurements were made at 0, 12, 24 and 48 hours after admission to the study, using an ELISA technique. These parameters were correlated with the Marshall multiple organic dysfunction score and survival. Results: Mean age of study subjects was 70 years, the APACHE II score was 16.9±6 and the Marshall score was 6.8±3.6. Sepsis was of pulmonary origin in 56% of patients and intra abdominal in 32%. Mortality was 36%. TNFa increased during the study period (24.1 pg/ml initially and 37.8 pg/ml at 24 hours, with a slight posterior reduction, p<0.02). These levels had no association with mortality or organic dysfunction. IL6 remained elevated during the first hours and had a tendency to decrease thereafter. Deceased patients had higher values than survivors (306 pg/ml and 55.4 pg/ml respectively, p=0.011). Its values were tightly correlated with Marshall score, with the number of failing organs, with the presence of shock and with probability of dying during hospitalization. IL1ß remained low and was not associated with clinical parameters. Conclusions: There is a tight correlation between the elevation of IL6 and the severity of the Systemic Inflammatory Response and mortality in these patients with sepsis.

Psychosocial factors such as depression and anxiety also contribute to this impairment. Aim: To evaluate: a) the impact of COPD on quality of life, and b) the effect of 10 weeks of exercise training on exercise performance and on QoL. Patients and methods: The Spanish version of the Chronic Respiratory Questionnaire (CRQ) was applied to 55 COPD patients (FEV1 37 ± 13% pred) for the assessment of QoL and in 30 of them submitted to exercise training for 10 weeks. Exercise performance was evaluated by measuring: six-minute walking distance, maximal workload (Wmax), maximal O2 consumption (VO2max) as well as endurance time, blood lactic acid, dyspnea and leg fatigue during a submaximal exercise. Trained patients were evaluated before and after training. Results: COPD patients showed a reduction (mean ± SD) in the four domains of the CRQ: dyspnea (3.1 ± 0.9); fatigue (4.3 ± 1.3); mastery (4.65 ± 1.3), emotional function (4.1 ± 0.97), and in Wmax and VO2max (52 ± 16 Watt and 970 ± 301 ml/min). No significant relationship between the impairment in exercise tolerance and in QoL was observed. Exercise training significantly improved the four domains of QoL (p < 0.0001), Wmax (p < 0.05), VO2max (p < 0.02) and endurance time (p < 0.001). Isotime exercise measurements of dyspnea, leg fatigue and lactic acid decreased after training (p < 0.001, each). No significant relation between changes in QoL and changes in exercise performance were observed. Conclusions: Our results demonstrate that QoL is seriously impaired in patients with COPD and confirm: (a) the lack of relationship of QoL to the usually measured physiological parameters, and (b) the beneficial effect of exercise training on QoL through the reduction of symptoms. These findings stresses the need of measuring quality of life in our patients if we want to evaluate the impact of therapeutic procedures on well-being from the patients’ perspective.

The study of the methylation state of DNA in l5(q11-q13) using polymerase chain reaction, called methylation test, allows the diagnosis of most patients with Prader-Willi and Angelman syndromes, irrespective if the underlying molecular alteration is a deletion, uniparental disomy or a punctual imprinting mutation. Aim: To assess the effectiveness of methylation test in the diagnosis of Prader-Willi and Angelman syndromes. Patients and methods: Thirty seven cases with a presumptive diagnosis of Prader-Willi syndrome and 25 with the presumptive diagnosis of Angelman syndrome were studied. Methylation test was done in genomic DNA obtained from peripheral Iymphocytes. Results: Methylation test confirmed the clinical diagnosis in 11 of 37 patients with PraderWilli (30%) and 6 of 25 patients with Angelman syndrome (24%). Conclusions: Clinical criteria overestimate the diagnosis of Prader-Willi and Angelman syndromes. The initial diagnosis should be confirmed with the methylation test and, if necessary, with FISH that will detect most deletions in the region.

The Mean Corpuscular Volume (MCV), and the gammaglutamyl transpeptidase (GGT), are widely used although their predictive value is somewhat limited due to their low specificity. On the other hand, the Carbohydrate-deficient transferrin (CDT) described in the eighties is highly specific and would be of value in early detection of problem drinking. Aim: To compare the sensitivity and specificity of CDT, GGT, and MCV in order to evaluate their single and combined use as markers for detection of heavy drinking behaviour. Patients and Methods: CDT, GGT, and MCV values were determined in blood samples from (a) alcoholics (drinking more than 100 9 alcohol/day; n=47) and (b) healthy volunteers, teetotalers from the Church of Saints of Later Days (n=34). At the time of sampling alcoholics were presently drinking or had been abstinents for no more than six weeks. ROC curves were used to determine the best cut-off point for each marker. Results: Sensitivity was found to be similar for all three markers. Specificity was found higher for GGT (90.9%) and CDT (91.0%). The combined use of MCV, GGT and CDT, that is, when at least one of the markers is altered, was shown to detect 83% of the patients. No correlation was observed between the markers and the level of alcohol intake. Conclusions: CDT could be of value as a marker to detect heavy drinking when used with GGT and MCV values combined. CDT is particularly higher in drinking alcoholics and remains significantly high for at least six weeks after they stop drinking.(Rev Méd 2001; 129: 375-81) <![CDATA[Valores de referencia para proteína transportadora de hormona de crecimiento en una población pediátrica normal]]> https://scielo.conicyt.cl/scielo.php?script=sci_arttext&pid=S0034-98872001000400006&lng=es&nrm=iso&tlng=es Circulating concentrations of the high affinity growth hormone binding protein (GHBP) may be a marker of GH receptor density as well as GH sensiffvity. Goal: To determine values of GHBP for a normal Chilean pediatric population. Methods: We determined GHBP levels in 73 males and 73 females between 4 to 15.5 years and 4 to 16.8 years respectively, divided in 7 groups according to age and puberal status. Results: The population was normally distributed in weight, height and body mass index (BMI). GHBP activity increased up to Tanner IV in males and Tanner III in females, and decreased slightly thereafter in Tanner V and IV respectively. There was a significant difference between GHBP levels of preschool children and those found in Tanner II to V in both sexes (p<0.05). In adition, we found a positive correlation between GHBP vs weight, height and BMI (p<0.001) in males and females. Conclusion: The availability of this methodology allows us to establish the normative value of GHBP in our population and provides useful information to interpret GH circulating levels in children with growth disorders.(Rev Méd Chile 2001; 129: 382-9) <![CDATA[Realimentacion digestiva en pancreatitis aguda: ¿Cuándo y cómo?]]> https://scielo.conicyt.cl/scielo.php?script=sci_arttext&pid=S0034-98872001000400007&lng=es&nrm=iso&tlng=es Background: Digestive refeeding in acute pancreatitis represent a dificult issue. It requires the rsolution of intestinal ileus and carries a risk of reactivation. Aim: To evaluate criteria that may guide in early refeeding avoiding unnecesary prolonged fasting. Patients and methods: Thirty patients with acute pancreatitis were evaluated in a prospective trial. The severity of the pancreatitis was evaluated according to APACHE II score and Balthazar CT scan altertions. The criteria proposed to start early refeeding were abscence of nausea and vomiting, decreased abdominal pain, presence of bowel sounds and lowering of serum amylase levels. Balthazar CT scan clasification, was used to decide between oral or enteral refeeding. Results. Eighty percent of patients had alterations in pancreatic density, necrosis or pancretic or peripancreatic liquid collections in the CT scan (correspondig to Balthazar stages C,D,or E). Ten patients fullfilled the criteria for enteral refeeding at 8.1 ± 3.5 days (range 3 to 15 days), and 21 patients fulfilled criteria fo enteral refeeding at 8.7±4.5 (range 4-19). No patient had a reactivation of his pancreatitis. Conclusions. Digestive refeeding can be done safely by using the criteria proposed in this study. Pancreatic necrosis or peripancreatic fluid collections do not contraindicate refeeding. Oral feeding may be employed (as the first option) in selected patients, without increasing the riskof complication, regardless of CT scan alterations of the pancreas (Rev Méd Chile 2001;129: 396-391) <![CDATA[Complicaciones en niños con varicela en cuatro hospitales de Santiago- Chile: Espectro clínico y estimación de costos directos]]> https://scielo.conicyt.cl/scielo.php?script=sci_arttext&pid=S0034-98872001000400008&lng=es&nrm=iso&tlng=es Background: The knowledge of varicella complications and their associated cost may help for a better evaluation of varicella immunization benefits. Aim: To determine frequency, type, outcome and affected population of varicella complications in children requiring hospitalization, and to estimate their direct costs. Material and methods: Retrospective analysis of medical records of children admitted to four hospitals in Santiago, Chile, due to varicella complications between January 1997 and February 1999. Calculation of direct costs of hospitalizations in a sample of 30 patients. Results: One hundred fifty four patients were identified, 74% were younger than 5 years old, only one was immunocompromised. Complications identified were skin and soft tissue infections in 63%, invasive infections in 25,3%, neurological in 7.1% and miscellaneous in 4,5%. Staphylococcus aureus and Group A ß-haemolytic Streptococcus (GABS) were predominantly isolated. S. aureus was the main agent identified in superficial infections and GABS in invasive infections (sterile sites). Two patients died due to invasive infections (streptococcal toxic shock and S. aureus septicaemia) and 11 required surgical procedures. The average cost per hospitalization was US$ 600 in public hospitals and US$ 1,800 in the private hospital. Conclusions: Varicella complications requiring hospitalization are due mainly to bacterial infections and they affect immunocompetent toddlers. These complications can be severe and even fatal.

Aim: To study infant mortality differentials from congenital malformations with linked records, in the 1993 to 1995 Chilean birth cohorts. Material and methods: Analysis of mortality differentials in 1993,1994 and 1995 birth cohorts. Multivariate logistic regression of mortality from congenital diseases. Results: Univariate analysis showed that mortality is highest in the Southern regions of the country (VII to XII) and in rural areas. It is also higher in children from older and from very young mothers, it increases along with the birth order of the child and decreases with increasing educational level of the mother. Multiple logistic regression analysis, confirmed the higher mortality in the Southern regions, aged mothers, high birth order of the child and low educational level of the mother. However no significant influence of rurality nor greater mortality in children of very young mothers was found. Conclusions: These results can be attributed to the fact that this type of analysis permits the control with other variables. Although the mortality data showed interesting relationships with the independent variables, a registry of all live births and stillbirths with congenital anomalies, that would provide greater numbers and data on non fatal anomalies, would be desirable to better study their causal factors.

Aim: To assess the techniques and errors in the use of metered dose inhalers among patients and health care professionals. Material and methods: Evaluation of the inhaling technique, using a validated questionnaire, used by 68 patients, 30 physicians and 30 nurses working in a hospital at Concepción, Chile. Results: The "closed mouth" technique is used by 84% of patients, 40% of physicians and 73% of nurses. The rest uses the "open mouth" technique. The aerochamber is used by 12% of patients, 37% of physicians and 27% of nurses. The most frequent inhaling errors detected were not shaking the inhaler (26% of patients, 30% of physicians and 7% of nurses), not applying the puff at the start of inspiration (28% of patients, 7% of physicians and 13% of nurses), and not maintaining an apnea after the inhalation (41% of patients, 7% of physicians and 10% of nurses). Sixty percent of patients, 67% of physicians and 40% of nurses have not received instructions about the inhaler use. Conclusions: There is a high frequency of errors in the use of inhalers and most users have not been trained in its use.

We report a 49 years old woman with a multiple myeloma that was admitted due to a superior vena cava syndrome caused by a central venous catheter used for chemotherapy for 20 weeks. She was successfully treated with thrombolysis, angioplasty and stent placement. The patient died 7 months later due to the underlying disease. Long term catheters are the responsible for 20 to 30% of superior vena cava syndromes. Endovascular treatment of the syndrome is successful in 60 to 100% of cases with a symptomatic relapse in 4 to 45% of patients.

We report a 69 years old woman with a history of one month of vertigo, nausea, vomiting and diarrhea. She was admitted dehydrated ad stuporous, and initial laboratory values showed a serum sodium of 96 mEq/L She was treated with dextrose 5% and 3% NaCI. Serum sodium raised to 120 mEq/L at the next day and the level of consciousness improved. At the 4th day of admission, the patient was again stuporous and with spastic quadriplegia. A magnetic resonance imaging showed a central and symmetrical pontine lesion on T1 and T2 weighed images. Thereafter, the patient experienced a progressive improvement of her neurological condition and was discharged three months later, moving her lower limbs. Nine month later she was able to walk.

The doubt is outlined moreover, when most of the investigations performed with oral estrogens in animals show an antiatherogenic effect, while the few experimental studies that hare been carried out with estrogen patches show contradictory results. We will have to wait for more extensive clinical trials to be able to know if the transdennic estrogens are really cardioprotective, however if we want to achieve some cardiovascular risk improvement with the current knowledge we will probably have to support the use of oral estrogens.

Unambiguous and objective propositions about this origin are that a live organism is an ontogenetically programmed and integrated organisation, that the origin condition has the greater influence on other processes, that in pluricellular organisms, no organ or tissue can be considered critical to establish origins and that the origin must be established by endogenous elements. Several hypotheses about the origin of life are discarded. The integration between oocyte cytoplasm and the genetic material that it receives, that culminates in the first genome replication, is proposed as the process that gives origin to the individual. This process occurs in all living organisms.
