Obesity is positively Associated with Depression in Older Adults: Role of Systemic Inflammation / 生物医学与环境科学（英文）

OBJECTIVE@#We aimed to explore the association between obesity and depression and the role of systemic inflammation in older adults.@*METHODS@#Adults ≥ 65 years old ( n = 1,973) were interviewed at baseline in 2018 and 1,459 were followed up in 2021. General and abdominal obesity were assessed, and serum C-reactive protein (CRP) levels were measured at baseline. Depression status was assessed at baseline and at follow-up. Logistic regression was used to analyze the relationship between obesity and the incidence of depression and worsening of depressive symptoms, as well as the relationship between obesity and CRP levels. The associations of CRP levels with the geriatric depression scale, as well as with its three dimensions, were investigated using multiple linear regressions.@*RESULTS@#General obesity was associated with worsening depression symptoms and incident depression, with an odds ratio ( OR) [95% confidence interval ( CI)] of 1.53 (1.13-2.12) and 1.80 (1.23-2.63), especially among old male subjects, with OR (95% CI) of 2.12 (1.25-3.58) and 2.24 (1.22-4.11), respectively; however, no significant relationship was observed between abdominal obesity and depression. In addition, general obesity was associated with high levels of CRP, with OR (95% CI) of 2.58 (1.75-3.81), especially in subjects free of depression at baseline, with OR (95% CI) of 3.15 (1.97-5.04), and CRP levels were positively correlated with a score of specific dimension (life satisfaction) of depression, P < 0.05.@*CONCLUSION@#General obesity, rather than abdominal obesity, was associated with worsening depressive symptoms and incident depression, which can be partly explained by the systemic inflammatory response, and the impact of obesity on depression should be taken more seriously in the older male population.

Chlamydia trachomatis infection in the genital tract is associated with inflammation and hypospermia in the infertile male of China / 亚洲男科学杂志(英文版)

Chlamydia trachomatis (CT) infection is the most prevalent sexually transmitted bacterial disease worldwide. However, unlike that in female infertility, the role of CT infection in male infertility remains controversial. The objective of this retrospective study was to explore the impacts of CT infection in the genital tract on sperm quality, sperm acrosin activity, antisperm antibody levels, and inflammation in a large cohort of infertile males in China. A total of 7154 semen samples were collected from infertile male subjects, 416 of whom were CT positive (CT+ group) and 6738 of whom were CT negative (CT- group), in our hospital between January 2016 and December 2018. Routine semen parameters (semen volume, pH, sperm concentration, viability, motility, morphology, etc.), granulocyte elastase levels, antisperm antibody levels, and sperm acrosin activity were compared between the CT+ and CT- groups. Our results showed that CT infection was significantly correlated with an abnormally low semen volume, as well as an increased white blood cell count and granulocyte elastase level (all P < 0.05) in the semen of infertile males; other routine semen parameters were not negatively impacted. The antisperm antibody level and sperm acrosin activity were not affected by CT infection. These findings suggested that CT infection might contribute to inflammation and hypospermia but does not impair sperm viability, motility morphology, and acrosin activity or generate antisperm antibodies in the infertile males of China.

Gender dysphoria: prejudice from childhood to adulthood, but no impact on inflammation. A cross-sectional controlled study

Abstract Introduction Gender dysphoria (GD) is characterized by a marked incongruence between experienced gender and one's gender assigned at birth. Transsexual individuals present a higher prevalence of psychiatric disorders when compared to non-transsexual populations, and it has been proposed that minority stress, i.e., discrimination or prejudice, has a relevant impact on these outcomes. Transsexuals also show increased chances of having experienced maltreatment during childhood. Interleukin (IL)-1β, IL-6, IL-10 and tumor necrosis factor-alpha (TNF-α) are inflammatory cytokines that regulate our immune system. Imbalanced levels in such cytokines are linked to history of childhood maltreatment and psychiatric disorders. We compared differences in IL-1β, IL-6, IL-10 and TNF-α levels and exposure to traumatic events in childhood and adulthood in individuals with and without GD (DSM-5). Methods Cross-sectional controlled study comparing 34 transsexual women and 31 non-transsexual men. They underwent a thorough structured interview, assessing sociodemographic information, mood and anxiety symptoms, childhood maltreatment, explicit discrimination and suicidal ideation. Inflammatory cytokine levels (IL-1β, IL-6, IL-10 and TNF-α) were measured by multiplex immunoassay. Results Individuals with GD experienced more discrimination (p = 0.002) and childhood maltreatment (p = 0.046) than non-transsexual men. Higher suicidal ideation (p < 0.001) and previous suicide attempt (p = 0.001) rates were observed in transsexual women. However, no differences were observed in the levels of any cytokine. Conclusions These results suggest that transsexual women are more exposed to stressful events from childhood to adulthood than non-transsexual men and that GD per se does not play a role in inflammatory markers.

Doença crítica crônica: estamos salvando ou criando vítimas? / Chronic critical illness: are we saving patients or creating victims?

RESUMO Os avanços tecnológicos que permitem dar suporte às disfunções de órgãos levaram a um aumento nas taxas de sobrevivência para a maioria dos pacientes críticos. Alguns destes pacientes sobrevivem à condição crítica inicial, porém continuam a sofrer com disfunções de órgãos e permanecem em estado inflamatório por longos períodos. Este grupo de pacientes críticos foi descrito desde os anos 1980 e teve diferentes critérios diagnósticos ao longo dos anos. Sabe-se que estes pacientes têm longas permanências no hospital, sofrem importantes alterações do metabolismo muscular e ósseo, apresentam imunodeficiência, consomem quantias substanciais de recursos de saúde, têm reduzida capacidade funcional e cognitiva após a alta, demandam uma considerável carga de trabalho para seus cuidadores, e apresentam elevadas taxas de mortalidade em longo prazo. O objetivo desta revisão foi apresentar as evidências atuais, em termos de definição, fisiopatologia, manifestações clínicas, tratamento e prognóstico da doença crítica persistente.

ABSTRACT The technological advancements that allow support for organ dysfunction have led to an increase in survival rates for the most critically ill patients. Some of these patients survive the initial acute critical condition but continue to suffer from organ dysfunction and remain in an inflammatory state for long periods of time. This group of critically ill patients has been described since the 1980s and has had different diagnostic criteria over the years. These patients are known to have lengthy hospital stays, undergo significant alterations in muscle and bone metabolism, show immunodeficiency, consume substantial health resources, have reduced functional and cognitive capacity after discharge, create a sizable workload for caregivers, and present high long-term mortality rates. The aim of this review is to report on the most current evidence in terms of the definition, pathophysiology, clinical manifestations, treatment, and prognosis of persistent critical illness.

A hipoalbuminemia parece estar associada a uma maior taxa de hospitalização nos pacientes em hemodiálise / Hypoalbuminemia seems to be associated with a higher rate of hospitalization in hemodialysis patients

Resumo Introdução: Anemia, inflamação e hipoalbuminemia são complicações frequentemente observadas em pacientes submetidos à hemodiálise crônica. Existem poucos dados nacionais que avaliam a associação dessas condições à morbidade e mortalidade especialmente considerando a região nordeste do país onde a ocorrência de anemia e desnutrição é elevada. Objetivo: O objetivo desse estudo foi avaliar o impacto da presença da anemia, inflamação e hipoalbuminemia sobre os desfechos clínicos (óbito e hospitalização) de pacientes sob hemodiálise. Método: Trata-se de um estudo de coorte prospectivo observacional com pacientes pre avaliados 221 pacientes adultos, considerando-se os valores de hemoglobina, proteína C reativa (PCR), albumina sérica no início do estudo. A ocorrência de hospitalização e óbito foi computada em um seguimento aproximado de 13 meses. Resultados: A ocorrência de hospitalização e óbito não diferiu entre os grupos com e sem anemia (Hb ≤ 10g/dL) ou inflamação (PCR ≥ 0,5mg/dL). Houve um maior número de hospitalização entre os pacientes com hipoalbuminemia. A albumina não apresentou correlação com os níveis séricos de PCR. Observou-se um menor tempo livre de hospitalização entre os pacientes com hipoalbuminemia (p = 0,008), houve uma tendência de menor tempo livre de hospitalização entre os pacientes com PCR aumentado (p = 0,08), e a anemia não se relacionou com o tempo livre de hospitalização. Não houve diferença na sobrevida em relação à presença de anemia, inflamação e hipoalbuminemia. A análise de regressão de Cox apontou a hipoalbuminemia como fator independente relacionado à hospitalização, mesmo após ajustes para idade, presença de diabetes, PCR e hemoglobina. Conclusão: A hipoalbuminemia, e não anemia ou inflamação, mostrou-se um marcador independente de hospitalização em pacientes submetidos à hemodiálise.

Abstract Introduction: Anemia, inflammation and hypoalbuminemia are frequent disorders among patients underwent hemodialysis. There are few national data, particularly from Northeast region where anemia and malnourished were common findings, analyzing the association between these conditions and clinical outcomes. Objective: The aim of this study was to evaluate the impact of the presence of anemia, inflammation and hypoalbuminemia on clinical outcomes (death and hospitalization) of hemodialysis patients. Methods: In this prospective observational study 221 adult patients were evaluated, considering the presence of anemia (hemoglobin ≤ 10 g/dL), inflammation (C-reactive protein (CRP) ≥ 0,5 mg/dL) and hypoalbuminemia (albumin < 3,8 g/ dL) at baseline. Clinical outcomes were recorded over 13 months. Results: The occurrence of hospitalization and death did not differ between the groups with and without anemia or inflammation. Patients with hypoalbuminemia had more hospitalizations, and the presence of hypoalbuminemia was associated with shorter hospitalization event-free time (p = 0.008). There was a trend of shorter hospitalization event-free time among patients with increased PCR (p = 0.08). There was no correlation between albumin and CRP levels. The presence of anemia, inflammation and hypoalbuminemia were not associated with lower survival. Adjusting for confounders, hypoalbuminemia was a predictor of hospitalization in hemodialyzed patients. Conclusion: The presence of hypoalbuminemia, but not anemia or inflammation, was able to predict hospitalization in hemodialysis patients.

Síndrome metabólica, aterosclerose e inflamação: tríade indissociável? / Metabolic syndrome, atherosclerosis and inflammation: an inseparable triad?

Observa-se, nas populações mundiais, aumento do sedentarismo e aumento do consumo de gorduras e açúcares, sendo estes vinculados normalmente aos alimentos industrializados. A consequência disso rapidamente se manifestou no aumento do sobrepeso/obesidade e na instalação de alterações fisiológicas e metabólicas, como a Síndrome Metabólica, que é representada por alterações na glicemia, nos lipídeos e na pressão arterial. Há evidências de ligação estreita entre estas alterações e os processos inflamatórios, que também podem estar associados ao estresse oxidativo. Estas condições levam à patogênese das alterações vasculares ou intensificam os processos metabólicos que acompanham a Síndrome Metabólica. O objetivo desta revisão foi comparar as inúmeras referências literárias que mostram correlação entre os componentes da Síndrome Metabólica e o aumento dos mediadores de inflamação. Para isso, utilizou-se Pubmed, Scopus, Lilacs e Scielo como base de dados, sendo que os artigos selecionados dataram principalmente dos últimos cinco anos.

Populations all over the world are increasingly inactive and are consuming increasing quantities of fats and sugars, which is generally linked to industrially processed foods. The consequences have rapidly manifest as an increase in overweight/obesity and in physiological and metabolic changes, such as the Metabolic Syndrome, which is a series of changes in glycemia, lipids and blood pressure. There is evidence of a close relationship between these changes and inflammatory processes, which can also be linked to oxidative stress. These conditions lead to the pathogenesis of vascular abnormalities or intensify metabolic processes that accompany the metabolic syndrome. The objective of this review is to compare the large number of bibliographic references that show correlations between components of the Metabolic Syndrome and increases in the mediators of inflammation. The publications reviewed were located using the Pubmed, Scopus, Lilacs and Scielo databases and the majority of the articles selected were published within the last 5 years.

Long-term Outcome of Cochlear Implant in Patients with Chronic Otitis Media: One-stage Surgery Is Equivalent to Two-stage Surgery

This study compared long-term speech performance after cochlear implantation (CI) between surgical strategies in patients with chronic otitis media (COM). Thirty patients with available open-set sentence scores measured more than 2 yr postoperatively were included: 17 who received one-stage surgeries (One-stage group), and the other 13 underwent two-stage surgeries (Two-stage group). Preoperative inflammatory status, intraoperative procedures, postoperative outcomes were compared. Among 17 patients in One-stage group, 12 underwent CI accompanied with the eradication of inflammation; CI without eradicating inflammation was performed on 3 patients; 2 underwent CIs via the transcanal approach. Thirteen patients in Two-stage group received the complete eradication of inflammation as first-stage surgery, and CI was performed as second-stage surgery after a mean interval of 8.2 months. Additional control of inflammation was performed in 2 patients at second-stage surgery for cavity problem and cholesteatoma, respectively. There were 2 cases of electrode exposure as postoperative complication in the two-stage group; new electrode arrays were inserted and covered by local flaps. The open-set sentence scores of Two-stage group were not significantly higher than those of One-stage group at 1, 2, 3, and 5 yr postoperatively. Postoperative long-term speech performance is equivalent when either of two surgical strategies is used to treat appropriately selected candidates.

Relación de la ingesta de grupos de alimentos con la proteína C-reactiva en adultos sanos en la ciudad de Mexicali, Baja California, México / Relationship of food groups intake and C-reactive protein in healthy adults from Mexicali, Baja California, México

La proteína C-reactiva ultrasensible (PCR-us) es un biomarcador importante en procesos inflamatorios. El objetivo del estudio fue examinar la relación entre la concentración de la PCR-us de adultos aparentemente sanos, con su patrón alimentario característico del norte de México. A una muestra de 72 profesores universitarios se les realizó una valoración clínica y antropométrica y se les cuantificó la PCR-us con un ensayo inmunoenzimométrico (EIA). Los profesores además contestaron un cuestionario de frecuencia de consumo de alimentos, del cual se estimaron las raciones de grupos de alimentos con el programa ESHA. La edad promedio de los participantes fue 49,75 ±10,05 años y la concentración de PCR-us tuvo un promedio de 1,66 (0,97 a 3,52) mg/L. La magnitud de la asociación entre el consumo de frutas y el nivel de PCR-us fue protectora de acuerdo con el análisis de regresión logística cuya Razón de Momios (RM) fue de 0,23 (95% IC: 0,05 a 1,03), mientras que para los vegetales la RM fue de 0,66 (95% IC: 0,12 a 3,68). Por otro lado, los alimentos proteicos, lácteos, aceites y grasas se asociaron con niveles elevados de la PCR-us. En conclusión, la menor concentración de la PCR-us se asoció con la mayor ingesta de los grupos de frutas y vegetales, y en menor grado con los cereales.

The high sensitivity C-reactive protein (hs-CRP) is an important biomarker in inflammatory processes. The objective was to analyze the relationship between the concentrations of hs-CRP in adults from a northern Mexico region with their typical food intake patterns. A sample of 72 university professors underwent clinical and anthropometric assessments and their hs-CRP levels were quantified with an immunoenzymometric assay. Additionally, they filled out a food intake frequency questionnaire, from which the servings of different food groups were obtained with the ESHA software. The average age of participants was 49.75 ± 10.05 years and the average hs-CRP concentration was 1.66 (0.97, 3.52) mg/L. The value of the association between fruit consumption and hs-CRP level was protective, according to the logistic regression analysis, being the Odds Ratio (OR) 0.23 (95% CI: 0.05, 1.03); while for vegetables the OR was 0.66 (95% CI: 0.12, 3.68). Furthermore, high protein content foods, dairy products, oils and fats were associated with elevated levels of hs-CRP. In conclusion, in our study, the intake of some food groups like fruits and vegetables, and to a lesser extent cereals, were associated with low values of hs-PCR.

Depression, Inflammatory Process and Medical Disorder.

Depression is well recognized as a major public health problem throughout the world. This article efforts to explore a pathway that links depression, inflammatory process and medical disorder. Associations linking inflammation and chronic immune activation with depression have been found, particularly in medical disorders with inflammatory pathopathyology. Acute coronary syndrome is given as an example of how the inflammatory process might result in depression.

Malnutrition-inflammation syndrome in a hemodialysis population: the influence of polymorphic IL-6-174 and IL-10-1082 genes.

AIM: To find out inflammation prevalence in hemodialysis patients and whether polymorphic gene IL-6-174 and IL-10-1082 had prominent factors in malnutrition inflammation syndrome. METHODS: A study on 81 patients who were on hemodialysis twice a week, 5 hours each session has been conducted. The subjects had no other co-morbidities and all of them used reprocessed diacetate cellulose dialyzers. RESULTS: It was obtained that CRP blood level (6.23+/- 5.57 mg/L), inflammation prevalence (23.5%), and malnutrition inflammation score (6.7) were lower compared with the data from Europe and the United States. Out of 64 patients examined, IL-6-174GG 95.31%, CC 3.13% and GC 1.56%, IL-1082AA 89.06%, GA 10.94%, but absence of GG genotype. Considering the scanty amount of allele C in IL-6-174 gene and G allele in IL-10-1082 gene, based on the statistic analysis performed, it did not reveal the influence of the difference in allele on the clinical manifestation. The proportion of these alleles were almost similar to that obtained in Korea, Japan and China, but it was different from that obtained in the US and in Europe. A very resolute impression was obtained in HD patients in Jakarta that IL-6-174GG gene was protective in nature whereas IL-10-1082 AA gene had a less considerable role. CONCLUSION: The prevalence of inflammation and malnutrition-inflammation parameters (CRP, malnutrition Inflammation Score) in our HD patients were lower than that reported in Western countries. This might be related to the low prevalence of IL-6-174C allele in our population.

GSTM1 and GSTP1 Polymorphisms as Potential Factors for Modifying the Effect of Smoking on Inflammatory Response

Inflammation has been known to be an important underlying condition for development of various diseases including cancer. The aims of this study were to investigate whether tobacco smoke exposure increases the level of inflammation biomarkers and the GSTM1 and GSTP1 gene polymorphisms are associated with inflam matory response due to tobacco smoke exposure. We measured urinary cotinine level in 300 healthy university students. Total serum TNF-alpha levels and blood WBC counts were determined to evaluate inflammatory response. Allelic loss of the GSTM1 and the GSTP1 (Ile105Val) polymorphism were determined by PCR and RFLP. Tobacco smoke exposure was found to be associated with increase of both TNF-alpha level and WBC count. Particularly, smokers with combination of GSTM1 null and GSTP1 AG or GG genotypes showed higher TNF-alpha level than those with the other genotype combinations (p=0.07). This result suggests that smoking may induce inflammation measured as TNF-alpha level or WBC count and combinations of the GSTM1 and GSTP1 polymorphisms may modify the effect of smoking on serum TNF-alpha level.

Classical fever of unknown origin (FUO): current causes in Mexico / Fiebre de origen indeterminado (FOI): causas actuales en México

Background. Causes of FUO change according to medical innovations, modifications of social circumstances, and emerging health risks. Aim. To describe the epidemiology of classical FUO, the time and procedures to achieve a definitive diagnosis, and to underline the variables useful in distinguishing FUO categories. Setting. A third-referral center in Mexico City. Methods. Patients admitted with prolonged fever were evaluated. Clinical charts of patients with classical FUO were assessed; comparisons between classical FUO categories were made. Results. 45 patients with 44.9 ± 17.2 years of age, previous fever duration of 51.2 ± 51.5 days, and 88.9% referred from other hospitals were evaluated. Nineteen patients had infectious causes; eight, neoplastic conditions; 12, inflammatory non-infectious diseases; one had another cause, and five were discharged with no etiologic diagnosis. Age, LDH levels, length of fever, and weight loss greater than 10 kg may be used to classify patients into a definite category. Conclusions. Classical FUO is an unusual presentation of frequent infectious diseases; SLE is the main cause within the inflammatory non-infectious conditions, and non-Hodgkin's lymphoma is the first cause of cancer. Some clinical and laboratory clues may be used to guide the study work up of patients with classical FUO.

Las causas de fiebre de origen indeterminado (FOI) varían de acuerdo con las innovaciones médicas o con modificaciones de las circunstancias sociales y riesgos para la salud. Objetivo. Describir la epidemiología de la FOI, el tiempo y procedimientos empleados para alcanzar un diagnóstico definitivo y evaluar las variables que pueden usarse para diferenciar sus categorías. Hospital. Centro de referencia de tercer nivel de la ciudad de México. Métodos. Se evaluó a pacientes con fiebre prolongada; los expedientes clínicos de aquellos con FOI fueron analizados y se compararon sus principales categorías. Resultados. Fueron evaluados 45 pacientes, de 44 ± 17.2 años de edad y duración promedio de la fiebre de 51.2 ± 51.5 días, de los cuales 88.9% habían sido referidos de otros hospitales. De ellos, 19 fueron diagnosticados con causas infecciosas, ocho con enfermedades neoplá-sicas, 12 con enfermedades inflamatorias no infecciosas, uno por alguna otra causa y cinco fueron dados de alta sin diagnóstico definitivo. La edad, niveles de DHL, la duración de la fiebre y la pérdida de peso mayor de 10 kg fueron marcadores útiles para clasificar a los pacientes en alguna de las categorías de la FOI. Conclusiones. La FOI es una manifestación inusual de enfermedades infecciosas frecuentes, el lupus erítematoso generalizado es la causa principal dentro de las condiciones inflamatorias no infecciosas y el línfoma no-Hodgkin en las neoplásicas. Algunas pistas clínicas y de laboratorio pueden emplearse para guiar el estudio de pacientes con FOI clásica.

Síndrome de Cogan / Cogan's Sryndrome

El síndrome de Cogan es una enfermedad inflamatoria crónica, infrecuente y de etiología no establecida, en la que se sugiere un carácter autoinmune. Se caracteriza, principalmente, por una queratitis intersticial, una sordera neurosensorial y una disfunción vestibular, que aparecen en un período menor de dos años. Otros tipos de compromisos tanto ocular, del oído interno y sistémico, como vasculitis, se pueden observar. Ningún hallazgo de laboratorio es específico de esta entidad. El diagnóstico diferencial es amplio. El tratamiento agresivo con inmunosupresores está indicado, especialmente cuando existe compromiso auditivo, ya que la pérdida de la audición es su principal secuela

Comparative study of the reactogenicity of a three-component acellular pertussis vaccine and whole-cell pertussis vaccine administered to healthy Singaporean infants.

The objective of this study was to assess and compare the reactogenicity of GlaxoSmithKline (GSK) Biologicals' diphtheria-tetanus-tricomponent acellular pertussis vaccine (DTPa) and the locally used combined diphtheria-tetanus-whole-cell pertussis vaccine (DTPw) as a primary vaccination course in healthy infants at the age of 3, 4 and 5 months. A phase IV, single-blinded, randomized comparative clinical study involved one hundred and eighty healthy infants with two study groups in a 2:1 ratio to receive either DTPa or DTPw vaccine which were administered intramuscularly at the right anterior-lateral aspect of the thigh. The incidence and intensity of local solicited symptoms such as pain, redness and swelling at injection site and general solicited symptoms such as fever and fussiness were evaluated. Serious adverse events were followed for one month after each vaccination. The overall incidence of local and general symptoms was significantly higher in the group receiving locally used DTPw vaccine as compared to the group receiving GSK DTPa vaccine. Solicited local symptoms, pain (47.4% vs 15.1%), redness (95.9% vs 84.9%) and swelling (46.2% vs 18.5%), were reported more frequently in the group receiving DTPw vaccine than in the group receiving DTPa vaccine. Fever (> or = 37.5 degrees C) (52% vs 14.6%) and fussiness (60.8% vs 33.6%) were also more commonly reported in the DTPw group. There were six serious adverse events reported (4 with DTPw and 2 with DTPa). None of them related to the study vaccines, as considered by the investigators. Thus it was found that GSK Biologicals' DTPa vaccine was significantly less reactogenic as compared to the locally used DTPw vaccine manufactured by Commonwealth Serum Laboratories when administered as a 3-dose primary vaccination course to healthy infants at the age of 3, 4 and 5 months in Singapore.

Incidencia de adrenalites em material de necropsia / Incidence of adrenalitis in necropsy material

Foram estudados casos de adrenalites em material de necropsias efetuadas na Faculdade de Medicina da USP, entre os anos de 1931 a 1981. De 131.466 necropsias 0,2 por cento exibiam adrenalites: 185 homens e 69 mulheres. Ocorrencia bilateral foi observada em 161 casos e unilateral em 46 (47 casos sem essa informacao). Os achados histopatologicos revelaram: 111 casos de tuberculose (43,7 por cento), 86 de paracoccidioidomicose (33,8 por cento), 24 com adrenalites cronicas inespecificas (9,5 por cento), 25 com adrenalites agudas e abcessos (9,8 por cento), 3 casos de histoplasmoses (1,2 por cento), 2 com febre tifoide (0,8 por cento), 2 com citomegalovirus (0,8 por cento) e 1 caso de leishmaniose (0,4 por cento). A grande incidencia de tuberculose e paracoccidioidomicose em glandula adrenal pode ser explicada pela grande ocorrencia dessas patologias em nosso pais, e por suas afinidades em acometer as supra-renais.

Algunos factores relacionados con la recuperación de pacientes con osteomielitis crónica. Cirugía HRHD de Arequipa 1995

El presente trabajo de investigación se realizó con los pacientes entre 15 y 65 años, cuyo diagnóstico fue osteomielitis crónica, egresados de los servicios de cirugía del Hospital Regional Honorio Delgado de Arequipa (HRHD), durante 1995. Esta investigación se hizo durante los meses de marzo a julio de 1996. Cuyo objetivo fue determinar si existe relación entre los factores como: la Educación Sanitaria brindada durante la hospitalización, el cumplimiento del tratamiento medicamentoso, la asistencia a controles médicos, el estado de nutrición, la ocupación del paciente, el ingreso económico familiar, los conocimientos del paciente acerca de su enfermedad y la recuperación del paciente con Osteomielitis Crónica. Para tal efecto se realizó un estudio de tipo descriptivo, con un diseño de correlación y de corte transversal. El total de la población con la que se trabajó fueron 29 pacientes. En la recolección de la información, primero se utilizó como instrumento, un formulario de recolección de datos de historias clínicas archivadas en la Unidad de Estadística del HRHD, posteriormente se realizaron visitas domiciliarias donde se aplicaron los otros instrumentos elaborados (guía de observación al paciente, guía de entrevista, cuestionario al paciente sobre conocimientos a cerca de su enfermedad). Los datos obtenidos fueron procesados estadísticamente, utilizando la prueba Ji cuadrado para la comprobación de la hipótesis, se trabajo con un margen de error del 10 por ciento, demostrándose que algunos de los factores que se relacionan con la recuperación del paciente con Osteomielitis Crónica son: la Educación Sanitaria recibida durante la hospitalización, el cumplimiento del tratamiento medicamentoso, la asistencia a controles médicos, el estado nutricional, el ingreso económico familiar y los conocimientos acerca de la enfermedad.
