Comparison of different nonsteroidal anti-inflammatory drugs for cesarean section: a systematic review and network meta-analysis / 대한마취과학회지

Background@#Cesarean section is associated with moderate to severe pain and nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly employed. The optimal NSAID, however, has not been elucidated. In this network meta-analysis and systematic review, we compared the influence of control and individual NSAIDs on the indices of analgesia, side effects, and quality of recovery. @*Methods@#CDSR, CINAHL, CRCT, Embase, LILACS, PubMed, and Web of Science were searched for randomized controlled trials comparing a specific NSAID to either control or another NSAID in elective or emergency cesarean section under general or neuraxial anesthesia. Network plots and league tables were constructed, and the quality of evidence was evaluated with Grading of Recommendations Assessment, Development and Evaluation (GRADE) analysis. @*Results@#We included 47 trials. Cumulative intravenous morphine equivalent consumption at 24 h, the primary outcome, was examined in 1,228 patients and 18 trials, and control was found to be inferior to diclofenac, indomethacin, ketorolac, and tenoxicam (very low quality evidence owing to serious limitations, imprecision, and publication bias). Indomethacin was superior to celecoxib for pain score at rest at 8–12 h and celecoxib + parecoxib, diclofenac, and ketorolac for pain score on movement at 48 h. In regard to the need for and time to rescue analgesia COX-2 inhibitors such as celecoxib were inferior to other NSAIDs. @*Conclusions@#Our review suggests the presence of minimal differences among the NSAIDs studied. Nonselective NSAIDs may be more effective than selective NSAIDs, and some NSAIDs such as indomethacin might be preferable to other NSAIDs.

Patterns, causality, severity, and preventability of adverse drug reactions: An observational study at a tertiary health-care center

Background: Adverse drug reactions (ADRs) are among the top leading causes of death, adversely affect the quality of life by increasing hospital stay, treatment cost, and morbidity. Spontaneous reporting of ADRs by health-care professionals (HCP) helps in signal detection and enables regulatory agencies to formulate drug use guidelines, issue warnings, or even ban/withdraw the drug from the market. Dissemination of knowledge regarding the patterns of ADRs seen in adverse drug reaction monitoring centers (AMCs) among HCP will enable to promote awareness on ADRs, help in early detection, and encourage them to be more vigilant so as to prevent recurrence of ADRs. Aims and Objectives: We conducted an observational study, with the following objectives. The aim of the study was to determine the pattern of ADRs reported to AMC at PESIMSR, causality assessment, severity score, and preventability. Materials and Methods: We conducted an observational, retrospective, and questionnaire-based study in PESIMSR AMC, Department of Pharmacology. The study period was between January 2016 and December 2016. All ADRs reported to the AMC in the above period were collected by convenient sampling method. Data collected includes patient characteristics such as age, gender, details of the reaction, details regarding suspected drugs, treatment, and outcome of ADR details as outlined in the standard CDSCO ADR notification form. Data were entered in SPSS version 22. Descriptive statistics used and values are expressed in frequency and percentages. Results: A total of 153 cases were taken for analysis. Among them, 52% were males and 48% were females. The incidence of ADRs was higher (26%) among third and fourth decade than other age groups. Most frequent classes of drugs causing ADRs are antibiotics (44%) followed by analgesics (10%) and oral hypoglycemics (6%). The most frequently reported ADRs were cutaneous reactions. According to the WHO scale for causality assessment, 59% were possible ADRs. According to modified Hartwig Seigel’s severity assessment scale, about 16% were assessed as severe reactions. About 39% were probably preventable ADRs as assessed by modified Schummock and Thornton scale. Conclusion: Hospital-based ADR monitoring and reporting programs aim to identify and quantify the risks associated with the use of drugs. This study gives an insight to emphasize the awareness to the health-care providers on vigilant monitoring of ADRs and promptly reporting the same so as to prevent the occurrence of the reactions in vulnerable population.

Stress reduction via neuro-emotional technique to achieve the simultaneous resolution of chronic low back pain with multiple inflammatory and biobehavioural indicators: A randomized, double-blinded, placebo-controlled trial / 中西医结合学报

BACKGROUND@#Beginning with the concepts of stress developed by Selye, an approach to stress and pain management, known as neuro-emotional technique (NET), has been developed. It is a treatment approach based on the principle that the stressor effects of dormant and/or current unresolved issues or trauma are what determine one's bodily responses. These responses are relatively personalized to the conditioned, experiential and emotional reality of the individual.@*OBJECTIVE@#To determine the effect of NET on patients with chronic low back pain (CLBP) over time.@*DESIGN, SETTING, PARTICIPANTS, AND INTERVENTIONS@#In a randomized, double-blinded, placebo-controlled study conducted in a single clinic, NET or control treatments were given twice weekly for 4 weeks in a population of 112 patients.@*MAIN OUTCOME MEASURES@#Outcome measures, including Oswestry Disability Index, Quadruple Visual Analogue Scale, the psychoneuroimmunology markers of blood serum levels of C-reactive protein, tumour necrosis factor-α, interleukin-1 (IL-1), IL-6, and IL-10, and 10 dimensions of the Short Form Health Survey scale, were assessed at baseline and at 1, 3 and 6 months following the intervention period.@*RESULTS@#Compared to placebo, NET produced clinical and statistical significance (P < 0.001) via declines of virtually all physiological, pain and disability markers, accompanied by gains in quality-of-life indicators at 0 (baseline), 1, 3 and 6 months. Reductions of the percentages of patients whose 5 biomarkers lay outside the normative range were achieved at 1, 3 and 6 months by NET but not control interventions.@*CONCLUSION@#A randomized, controlled trial of CLBP patients indicated that 8 NET interventions, compared to placebo, produced clinically and statistically significant reductions in pain, disability and inflammatory biomarkers, and improvements in quality-of-life measures.@*TRIAL REGISTRATION@#The trial was registered with the Australian and New Zealand Clinical Trials Registry (No. ACTRN12608000002381).

Tuberculosis case finding and case holding practices in selected Drug Abuse Treatment and Rehabilitation Centers (DATRCS) in Luzon, Philippines

@#<p style="text-align: justify;"><strong>Background and Objectives:</strong> Tuberculosis (TB) remains a public health problem in the Philippines despite trends indicating a decline in the burden of disease. Persons who use drugs who are confined in government-retained drug abuse treatment and rehabilitation centers (DATRCs) face an increased risk for TB because of the congestion in the facility coupled with the absence of guidelines on TB management specific to DATRCs. Thus, this study was conducted to document the current case finding and case holding practices as well as TB treatment pathway in six (6) Luzon-based, government-retained DATRCs.</p><p style="text-align: justify;"><strong>Methods:</strong> Key informant interviews were conducted with DATRC personnel involved in TB diagnosis and management in six selected DATRCs in Luzon, Philippines. Interviews were transcribed and coded for thematic analysis. We compared the DATRC practices with the provisions of the 2014 National TB Control Program (NTP) Manual of Procedures. Results were validated through a workshop with (a) a group of physicians and rehabilitation practitioners assigned in other DATRCs; and (b) a group of experts who have experience in managing or overseeing DATRCs in the country.</p><p style="text-align: justify;"><strong>Results:</strong> Two physicians and four nurses participated in the interviews. Variations in case finding and case holding practices in six DATRCs have been found. National guidelines exist for congregate settings but are more specific to jails/prisons, which are administratively and operationally different from DATRCs.</p><p style="text-align: justify;"><strong>Conclusion:</strong> Development of special guidelines for TB case finding and case holding in DATRCs as well as staff training on the latest NTP Manual of Procedures are recommended. However, gaps and inequities posed by the current set-up underscore the need to address health system-wide factors affecting the practice and performance of these facilities.</p><p style="text-align: justify;"><strong>Key Words:</strong> tuberculosis, case finding, case holding, drug abuse treatment and rehabilitation centers, Philippines</p>

Comparison of Spinal Canal Expansion Following Cervical Laminoplasty Based on the Preoperative Lamina Angle : A Simulation Study

Objective@#: Expansion in the spinal canal area (SCA) after laminoplasty is one of the critical factors to relieve the preoperative symptoms. No previous study has compared the increases in SCA achieved by open-door laminoplasty (ODL) and double door laminoplasty (DDL) according to the preoperative lamina angle (LA). This study was designed to clarify the relationship between the laminoplasty opening angle (OA)/laminoplasty opening size (OS) and increases in the SCA following ODL and DDL according to the preoperative LA using a simulation model. @*Methods@#: The simulation model was constructed and validated by comparing the clinical data of 64 patients who had undergone C3–C6 laminoplasty (43 patients with ODL and 21 patients with DDL). SCA expansion was predicted with a verified simulation model at various preoperative LAs (from 28° to 32°) with different OAs (40° to 44°) and OSs (10 mm to 14 mm) recruited from patient data. @*Results@#: The constructed simulation model was validated by comparing clinical data and revealed a very high degree of correlation (r=0.935, p0.05). The difference was significant when the preoperative LA was narrower or much wider. @*Conclusion@#: Based on clinical data, a simulation model was constructed and verified that could predict increases in the SCA following ODL and DDL. When applying this model, prediction in SCA increase using the OS parameter was more practical and compatible with clinical data. Both laminoplasties achieved enough SCA, and there was no significant difference between them in the usual range.

Tuberculosis in Selected Drug Abuse Treatment and Rehabilitation Centers (DATRCs) in Luzon, Philippines

Background and Objectives@#Tuberculosis (TB) continues to be a public health concern in the Philippines. Vulnerable populations in congregate settings such as drug abuse treatment and rehabilitation centers (DATRCs) have higher risks of TB transmission and infection. With the Duterte administration’s intensified campaign against illegal drugs, government-retained DATRCs are filled to capacity. There is an identified need to profile drug users and dependents living in DATRCs. Furthermore, national guidelines for TB management specific to this population is absent. A study was conducted to determine the profile of admitted clients diagnosed with TB, TB prevalence, treatment outcomes and choice of TB diagnostic modalities in six (6) Luzon-based DATRCs from 2013-2015.@*Methods@#All medical records of drug users admitted in this period were reviewed. Information on the total patient census was sought from DATRC heads and used to compute for prevalence.@*Results@#A total of 347 records were obtained. Overall TB prevalence in the study sites was 7,216 per 100,000 population. The typical individual diagnosed with TB in a DATRC was male, with a mean age of 35 years, with at least high school education, and unemployed. Weight loss and fatigue were the most common symptoms reported. The majority (79.83%) completed TB treatment in the DATRCs. Sputum microscopy and chest x-ray were both used for TB diagnosis in 92.80% (322) of the cases.@*Conclusion@#The high burden of TB in Luzon-based, government-retained DATRCs is alarming and underscore the critical need for standards and guidelines in the National Tuberculosis Control Program addressing the unique context of these facilities.

Anemia Screening, Prevalence, and Treatment in Pediatric Inflammatory Bowel Disease in the United States, 2010–2014 / 대한소아소화기영양학회지

PURPOSE: We examined the prevalence of anemia, annual screening for anemia, and treatment of anemia with iron among children with inflammatory bowel disease (IBD). METHODS: A retrospective study of U.S. pediatric patients with IBD was performed in the MarketScan commercial claims database from 2010–2014. Children (ages 1–21) with at least two inpatient or outpatient encounters for IBD who had available lab and pharmacy data were included in the cohort. Anemia was defined using World Health Organization criteria. We used logistic regression to determine differences in screening, incident anemia, and treatment based on age at first IBD encounter and sex. RESULTS: The cohort (n=2,446) included 1,560 Crohn's disease (CD) and 886 ulcerative colitis (UC). Approximately, 85% of CD and 81% of UC were screened for anemia. Among those screened, 51% with CD and 43% with UC had anemia. Only 24% of anemia patients with CD and 20% with UC were tested for iron deficiency; 85% were iron deficient. Intravenous (IV) iron was used to treat 4% of CD and 4% UC patients overall and 8% of those with anemia. CONCLUSION: At least 80% of children with IBD were screened for anemia, although most did not receive follow-up tests for iron deficiency. The 43%–50% prevalence of anemia was consistent with prior studies. Under-treatment with IV iron points to a potential target for quality improvement.

Perception of program administrators and student representatives on the implementation of return service agreement in selected institutions in the Philippines

Objectives@#The study aimed to determine the perception of program administrators and students on the implementation of return service agreement (RSA) in the Philippines. It examined the different components of, and opportunities, and challenges in the implementation of RSA of selected institutions.@*Methods@#Key informant interviews using a topic guide were conducted with ten program administrators and student representatives from selected institutions implementing a return service policy. Interviews were transcribed and responses in Filipino were translated to English. Open coding and focused coding were performed to identify categories and themes from the interview transcripts.@*Results@#Addressing human resource for health (HRH) needs of the country is a common rationale behind RSA implementation among the institutions sampled for the study. A notable difference in implementation arrangements is the manner of rendering service. Majority of RSA programs require promisors to be employed in any part of the Philippines in need of health workers, while other RSA programs recruit students from rural areas in order to deploy them later on in their hometowns. There is also an apparent lack of institutionalized mechanisms for job placement for students to fulfill their return service obligations. One challenge in most institutions is the need for a formal monitoring and evaluation scheme for the policy.@*Conclusion@#Integration of the voice of stakeholders is critical in the conceptualization, development, and implementation of RSA policies. This will ensure that issues attendant to operationalization are mitigated if not outrightly avoided.

A historical perspective of the mandatory service policy in the Philippines: A document analysis

@#<p><strong>BACKGROUND</strong>: The Philippines has, mandatory service policies to address the insufficiency and maldistribution of human resources particularly for health services. Despite being perceived as an appropriate intervention to bridge the aforementioned HRH gaps, the past and present implementations of such programs in the country have never been formally studied.</p><p><strong>OBJECTIVE</strong>: This paper aimed to present the history of mandatory service programs in the Philippines, look at their natures, and see how their different implementations relate to each other.</p><p><strong>METHODOLOGY</strong>: Using a qualitative document analysis method, administrative issuances and reports relevant to past and current implementations of mandatory service policies in the Philippines were obtained and reviewed.</p><p><strong>RESULTS</strong>: Mandatory service programs have been implemented in the country by institutions from both the private and public sectors as early as 1968. The focus of such has been mostly for government positions and specialized professions including physicians and scientists. While extensive efforts have been made through the years, the policies demonstrated fragmentation and recurring gaps in implementation. Such gaps include the lack of enabling policy mechanisms, formal monitoring and evaluation, and program institutionalization.</p><p><strong>CONCLUSION</strong>: The historical narrative of return service programs in the country is a potential source for the development of an overarching mandatory service policy framework for human resources in the Philippines, one that is specific to the context and setting of the country. By articulating policy issues identified, this paper provided a stepping-off point for future mandatory service program policy planning, implementation, evaluation, and institutionalization in the Philippines.</p>

Intravenous thrombolytic therapy for patients with ventricular assist device thrombosis: An attempt to avoid reoperation.

A growing number of patients are undergoing prolonged management of advanced heart failure with the use of continuous flow left ventricular assist devices (LVADs). Subsequently, an increasing number of patients are presenting with complications associated with these devices. Based on an analysis of three major LVAD institutions, the number of patients developing LVAD pump thrombosis may be much higher than originally projected.[1,2] The management of this highly feared complication continues to be challenging, as the population of LVAD patients is very heterogeneous and heavily burdened with comorbidities. The standard protocol of increasing anticoagulation may fail to achieve successful resolution of thrombus. Difficulty and poor prognosis may make reoperation less than desirable. Here, we present a case of successful thrombolysis following intravenous administration of tissue plasminogen activator in the Intensive Care Unit setting.

Oral herbal medicines for psoriasis: a review of clinical studies / 中国结合医学杂志

Various forms of complementary and alternative medicine are used in psoriasis. Among these, herbal medicines are frequently used as systemic and/or topical interventions either as a replacement for or in conjunction with conventional methods. The benefit of such use is unclear. This review is to provide an up-to-date review and discussion of the clinical evidence for the main kinds of herbal therapies for psoriasis. Searches of the biomedical databases PubMed (including MEDLINE), EMBASE and CINAHL were conducted in December 2011 which identified 32 clinical studies, all published in English. Twenty of these primarily tested topical herbal medicines and were thus excluded. The 12 studies that evaluated systemic use of herbal medicines were included in the review. Four were case series studies and the other 8 were controlled trials. In terms of interventions, 4 studies tested the systemic use of plant oils combined with marine oils and 8 studies tested multi-ingredient herbal formulations. The clinical evidence for plant and animal derived fatty acids is inconclusive and any benefit appears to be small. For the multi-herb formulations, benefits of oral herbal medicines were shown in several studies, however, a number of these studies are not controlled trials, a diversity of interventions are tested and there are methodological issues in the controlled studies. In conclusion, there is promising evidence in a number of the studies of multi-herb formulations. However, well-designed, adequately powered studies with proper control interventions are needed to further determine the benefits of these formulations. In addition, syndrome differentiation should be incorporated into trial design to ensure effective translation of findings from these studies into Chinese medicine clinical practice.

Evaluation of Potential Fungal Species for the in situ Simultaneous Saccharification and Fermentation (SSF) of Cellulosic Material

Three fungal species were evaluated for their abilities to saccharify pure cellulose. The three species chosen represented three major wood-rot molds; brown rot (Gloeophyllum trabeum), white rot (Phanerochaete chrysosporium) and soft rot (Trichoderma reesei). After solid state fermentation of the fungi on the filter paper for four days, the saccharified cellulose was then fermented to ethanol by using Saccharomyces cerevisiae. The efficiency of the fungal species in saccharifying the filter paper was compared against a low dose (25 FPU/g cellulose) of a commercial cellulase. Total sugar, cellobiose and glucose were monitored during the fermentation period, along with ethanol, acetic acid and lactic acid. Results indicated that the most efficient fungal species in saccharifying the filter paper was T. reesei with 5.13 g/100 g filter paper of ethanol being produced at days 5, followed by P. chrysosporium at 1.79 g/100 g filter paper. No ethanol was detected for the filter paper treated with G. trabeum throughout the five day fermentation stage. Acetic acid was only produced in the sample treated with T. reesei and the commercial enzyme, with concentration 0.95 and 2.57 g/100 g filter paper, respectively at day 5. Lactic acid production was not detected for all the fungal treated filter paper after day 5. Our study indicated that there is potential in utilizing in situ enzymatic saccharification of biomass by using T. reesei and P. chrysosporium that may lead to an economical simultaneous saccharification and fermentation process for the production of fuel ethanol.

Resultados da abordagem transeptal para a valva mitral com coração batendo / Results of beating heart mitral valve surgery via the trans-septal approach

OBJETIVO: A cirurgia da valva mitral pode ser feita via transatrial ou transeptal. Embora a transatrial seja a preferida, a via transeptal tem sido utilizada mais recentemente e tido um grande valor nas operações com o coração batendo. Mostramos a nossa experiência na cirurgia da valva mitral via transeptal com coração batendo e discutimos seus benefícios e problemas. MÉTODOS: Entre 2000 e 2007, 214 pacientes consecutivos foram operados com o coração batendo. A operação foi feita por via transeptal sem pinçamento da aorta, com o coração batendo e eletrocardiograma normal e em ritmo sinusal. RESULTADOS: A idade média foi de 56,03 ± 13,93 anos (intervalo: 19-86 anos; mediana: 56 anos). Havia 131 (61,2 por cento) pacientes do sexo masculino e 83 (38,8 por cento), do feminino. Foram utilizadas 108 (50,5 por cento) próteses biológicas e 39 (18,2 por cento) mecânicas. Reparo da valva foi feito em 67 (31,3 por cento) pacientes. A estadia hospitalar foi de 17,4 ± 20,0 dias (intervalo: 3-135 dias; mediana: 11 dias). Balão intra-aórtico foi utilizado em 12 (5,6 por cento) pacientes. A mortalidade hospitalar foi de 7,4 por cento. Reoperação para revisão de hemostasia foi necessária em 15 pacientes. CONCLUSÃO: A operação com o coração batendo é uma opção para proteção miocárdica em pacientes submetidos a cirurgia da valva mitral. A técnica é facilitada ao se usar a via transeptal, reduzindo a insuficiência aórtica e melhorando a visualização do aparato mitral.

OBJECTIVE: Mitral valve surgery can be performed through the trans-atrial or the trans-septal approach. Although the trans-atrial is the preferred method, the trans-septal approach has also been used recently and has a particular value in beating-heart mitral valve surgery. Herein we report our experience with beating-heart mitral valve surgery via trans-septal approach, and discuss its advantages and pitfalls. METHODS: Between 2000 and 2007, 214 consecutive patients were operated upon utilizing beating heart technique for mitral valve surgery. The operation was performed via transseptal approach with the aorta unclamped, the heart beating, with normal electrocardiogram and in sinus rhythm. RESULTS: Mean age was 56.03 ± 13.93 years (range: 19-86 years; median: 56 years). There were 131 (61.2 percent) males and 83 (38.8 percent) females. Of the prostheses used, 108 (50.5 percent) were biological, and 39 (18.2 percent) were mechanical. Mitral repairs were performed in 67 (31.3 percent) patients. Mean hospital stay was 17.4 ± 20.0 days (range: 3-135 days; median: 11 days). Intra-aortic balloon pump (IABP) utilization was required in 12 (5.6 percent) of 214 patients. One-month mortality was 7.4 percent, and re-operation for bleeding was needed in 15 (7 percent) patients. CONCLUSIONS: Beating-heart mitral valve surgery is an option for myocardial protection in patients undergoing mitral valve surgery. This technique is facilitated by the trans-septal approach due to reduced aortic insufficiency and improved visualization of the mitral apparatus.

Thoracoabdominal aortic aneurysms

Over the last 50 years, significant progress has been made in the surgical repair of thoracoabdominal aortic aneurysms [TAAA]. Improvements in perioperative care and surgical techniques have resulted in reductions in complication and mortality rates. Adjunctive use of distal aortic perfusion and cerebrospinal fluid drainage has been especially helpful, reducing the incidence of neurological deficits to 2.4%. Current research is aimed at improving organ preservation. This review focuses on the current diagnosis and management of TAAA

Estado actual del trasplante pulmonar / Lung transplantation: state of the art

Actualmente el trasplante pulmonar es considerado como tratamiento definitivo para algunas enfermedades pulmonares avanzadas. Los primeros trasplantes pulmonares experimentales en animales fueron realizados en los años 1940’s por el soviético Vladimir P. Demikhov. Sin embargo, pasaron aproximadamente dos décadas antes de que se realizara el primer trasplante pulmonar en humanos por el doctor James Hardy. Desafortunadamente los inicios clínicos del trasplante pulmonar no fueron muy exitosos debido a complicaciones quirúrgicas y efectos secundarios de los fármacos inmunosupresores. Gracias al mejoramiento de la técnica quirúrgica y al desarrollo de fármacos inmunosupresores más efectivos y menos tóxicos, la morbimortalidad ha disminuido significativamente. La selección y el cuidado del donador antes de la procuración de los órganos juegan un papel primordial en los resultados en el receptor. Debido a la escasez de donadores, algunas instituciones están utilizando criterios de selección más liberales con resultados satisfactorios. El manejo del paciente con trasplante pulmonar o del bloque cardiopulmonar requiere de un enfoque multidisciplinario que incluye al cirujano de trasplantes cardiotorácicos, al neumólogo, al anestesiólogo y al intensivista entre otros. En este artículo revisamos aspectos históricos y avances recientes en el manejo de estos pacientes incluyendo indicaciones y contraindicaciones, evaluación y cuidado del donador y del receptor, técnica quirúrgica y manejo peri- y posoperatorio.

Lung transplantation is currently considered an established treatment for some advanced lung diseases. The beginning of experimental lung transplantation dates back to the 1940's when the Soviet Vladimir P. Demikhov performed the first lung transplants in animals. Two decades later, James Hardy performed the first lung transplant in humans. Unfortunately, the beginning of clinical lung transplantation was hampered by technical complications and the excessive toxicity of immunosuppressive drugs. Improvement in the surgical technique along with the development of more effective and less toxic immunosuppressive drugs has led to a better outcome in lunt transplant recipients. Donor selection and management before organ procurement play a key role in the receptor's outcome. Due to the shortage of donors, some institutions are using more liberal selection criteria, reporting satisfactory outcomes. The approach of the lung and heart-lung transplant patient is multidisciplinary and includes the cardiothoracic transplant surgeon, pulmonologist, anesthesiologist, and intensivist, among others. Herein, we review some relevant historical aspects and recent advances in the management of lung transplant recipients, including indications and contraindications, evaluation of donors and recipients, surgical techniques and peripost-operative care.

Hallazgos patológicos en cerdos afectados con el síndrome del desmedro multisistémico postdestete de la República Argentina / Pathological findings in pigs affected by the postweaning multisystemic wasting syndrome in Argentina

El síndrome del desmedro multisistémico postdestete (PMWS) fue descrito por primera vez en Canadá en el año 1991 y desde entonces un número creciente de casos han sido diagnosticados en todo el mundo. En la Argentina, el PMWS fue reportado por primera vez recientemente. Se estudiaron 48 cerdos de 5 a 12 semanas de edad con signos característicos de PMWS procedentes de 19 granjas. Si bien se desconoce la distribución real del virus en nuestro país se observó desde el año 2001 un número creciente de granjas con PMWS y distribuidas en las principales provincias productoras. La histopatología fue una herramienta diagnóstica importante en casos sospechosos de PMWS con la observación de diferentes grados de lesión. En los animales estudiados las infecciones secundarias pudieron ser importantes, ya sea por patógenos oportunistas o por complicaciones bacterianas.

Postweaning multisystemic wasting syndrome was first described in Canada in 1991 and at present an increasing number of cases has been diagnosed worldwide. In Argentina the first cases of PMWS were reported recently. Forty eight 5 to 12 week old pigs with signs characteristic of PMWS from 19 farms were studied. Although the real distribution of the virus in our country is not known it was observed an increasing number of farms with PMWS distributed in the major producing provinces. The histopathology was an important tool in diagnosis of suspicious cases of PMWS with the observation of different degrees of lesion. In the studied animals, the secondary infections, either by opportunistic pathogens or secondary bacteria could be important.

Enzimas miocárdicas na cirurgia de revascularização sem circulação extracorpórea / Myocardial enzymes in revascularization surgery without extracorporeal circulation

INTRODUÇÃO: A cirurgia cardíaca com o coração batendo está sendo cada vez mais utilizada para minimizar danos cerebrais, renais e outros. Porém, a incidência de infarto nos períodos per e pós-operatório e seu efeito a longo prazo, especialmente quando esta técnica é comparada às tradicionais, ainda não foi totalmente esclarecida. CASUÍSTICA E MÉTODOS: Um estudo retrospectivo de 303 pacientes (122 sem CEC, 181 com CEC) foi realizado de fevereiro/97 a fevereiro/99. Dosagens de CK-MB e eletrocardiogramas foram avaliados nos períodos per e pós-operatório, troponina T (TnT) foi medida no período pós-operatório. Os dois grupos foram comparáveis quanto a idade (65 Ý 10 anos vs. 65 Ý 9 anos), classificações CCS e NYHA. RESULTADOS: O número médio de enxertos com CEC foi de 3,10 vs. 2,26 sem CE. Infarto peri-operatório, assim como morbidade e mortalidade (7/181 vs. 6/122) foram comparáveis. Apesar de mais elevados no grupo com CEC, os níveis pós-operatórios de CK-MB e troponina T não atingiram diferença estatística, tendo sido observados 21 infartos agudos por critérios bioquímicos que se distribuíram igualmente entre os grupos. Uma correlação inversa entre o número de enxertos e a liberação de troponina foi observada na fase inicial da nossa experiência sem CEC. Não houve relação entre a localização do enxerto e a incidência de infarto ou liberação de troponina. CONCLUSÃO: A proteção miocárdica, morbidade e mortalidade obtidas com as duas técnicas de revascularização estudadas foram semelhantes. Considerando os efeitos adversos da CEC, já documentados na literatura, particularmente sobre os sistemas neurológico, respiratório e renal sugerimos esta técnica como uma alternativa segura para a revascularização miocárdica

A randomized, controlled trial of pretreatment with finasteride in patients with benign prostate hyperplasia undergoing transurethral resection of the prostate: Its effects on perioperative bleeding and microvessel density

Objectives: (1) To evaluate the expression of prostatic microvessel density in patients with benign prostatic hyperplasia (BPH) treated with finasteride among Filipino patients. (2) To evaluate the effects of finasteride in perioperative bleeding in patients undergoing transurethral resection of prostate for BPHMaterials and Methods: Twenty (20) patients scheduled to undergo transurethral prostatic surgery for benign disease were randomized to pretreatment of finasteride 5 mg tablet once a day for 2 weeks before surgery. Perioperative bleeding parameters include serum hemoglobin determination one day before surgery and immediately 6 hours after the surgery and day 1 post-op. Parraffin blocks were sent for special immunohistochemical von Willebrand factor (factor 8) staining and microvessel density were analyzedResults: There was a significant difference in the mean decrease in serum hemoglobin level from the preoperative level to that measured in the immediate postoperative recovery period (4.2 +/- 2.30 gm/dL vs 7.4 +/- 3.63 gm/dL). However, there was no significant difference in the mean decrease in pre-operative serum hemoglobin level compared with the level measured one day after the procedure (8.9 +/- 8.01 gm/dL vs. 15.20 I 10.04 gm/dL). There was significantly less hemoglobin in the irrigation fluid in the finsteride group than in the control group (1.28 +/- 1.38 vs 7.92 +/- 6.34). Mean microvascular density in the finasteride group was 58.00 +/- 2.50 and in controls, 71.00 +/- 31.07Conclusion: Pretreatment with Finasteride 5 mg given daily for 2 weeks in patients with BPH undergoing TURP significantly decreases perioperative bleeding. Finasteride administration also decreases microvessel density in prostatic tissue. (Author)

The center for disease control-national nosocomial infection surveillance (CDC-NNIS) surgical patient risk index score and surgical site infections at UERMMMC

The study retrospectively reviewed 1,029 general surgery operations performed from September 1, 1991 to May 31, 1993 to find out the association between the occurrence of surgical site infection (SSI) and the Centers for Disease Control-National Nosocomial Infection Surveillance (CDC-AWS) surgical patient risk index scores. The index assigned 1 point for each of 3 risk factors: 1) American Society of Anesthesiologists (ASA) preoperative assessment class 3, 4 or 5; 2) an operational classified as either contaminated or dirty-infected; 3) an operation with a duration longer than a specified increased with increasing contamination (p=0.000) as well as increasing index scores (p=0.000). Looking at operations within the same category of contamination, SSI rates also increased with increasing scores among clean operations (p=0.944), clean-contaminated operations (p=0.000), contaminated operations (p=0.559), and dirty operations. SSI rates in this hospital series were compared to the 44-hospital CDC-NNIS report.
