RESUMEN
INTRODUCTION: the tibial slope has been identified as one of the factors associated with graft failure after anterior cruciate ligament (ACL) reconstruction; however, its relationship with functional results has been little studied. The main purpose of this study is to determine the effect of the tibial slope on functional recovery in patients undergoing reconstruction of the anterior cruciate ligament. MATERIAL AND METHODS: we included patients with a diagnosis of anterior cruciate ligament injury undergoing primary reconstruction, from May 2018 to May 2019, who had a complete radiographic and clinical record; also, the scores from questionnaires of the International Knee Documentation Committee (IKDC) and Lysholm scores were collected pre surgical procedures and throughout the one-year follow-up. The measurement of the tibial slope was performed in lateral knee X-rays from the electronic clinical record. A descriptive analysis of first intention was done, and to achieve the objectives, we compared 25 patients who had normal tibial slope that were selected randomly with 25 patients who had increased tibial slope. RESULTS: a total of 98 patients were included, 73 had a normal tibial slope (equal to or less than 12 degrees) and 25 with an increased tibial slope (greater than 12 degrees), the average age in both groups was 28.43 years for the group with normal tibial slope and 28.26 for patients with increased tibial slope. Regarding the functional assessment, the IKDC and Lysholm scores at the end of the follow-up were better for patients with normal tibial slope. Graft failure was only identified in the group with increased tibial slope. On the other hand, the comparative analysis with the control group randomly selected who had normal tibial slope, showed a better functional result assessed by IKDC score at the end of the follow-up for the group with normal tibial slope. CONCLUSION: patients undergoing ACL reconstruction and increased Tibial Slope have an inferior functional result at one year of follow-up assessed by IKDC, when compared with patients with normal tibial slope.
INTRODUCCIÓN: el slope tibial (inclinación) se ha identificado como uno de los factores asociados a la falla del injerto tras una reconstrucción de ligamento cruzado anterior (LCA); sin embargo, su relación con los resultados funcionales ha sido poco estudiada. El objetivo de este estudio es determinar el efecto del slope tibial en la recuperación funcional, en pacientes sometidos a reconstrucción de LCA. MATERIAL Y MÉTODOS: se incluyeron los pacientes con lesión de LCA sometidos a reconstrucción primaria, de Mayo de 2018 a Mayo de 2019, midiendo el slope tibial y recabando los puntajes de IKDC y Lysholm. Se elaboró un análisis descriptivo de primera intención y para alcanzar los objetivos se realizó una comparativa de 25 pacientes con slope tibial normal seleccionados aleatoriamente contra 25 pacientes con slope tibial aumentado. RESULTADOS: se incluyeron 98 pacientes, 73 contaban con un slope tibial normal y 25 con un slope tibial aumentado. Los puntajes de IKDC y Lysholm al final del seguimiento fueron mejores en los pacientes con slope tibial normal. La falla del injerto sólo se identificó en el grupo con slope tibial aumentado. Por otro lado, al análisis comparativo con el grupo control demostró un mejor resultado funcional al final del seguimiento valorado por IKDC en el grupo con slope tibial normal. CONCLUSIÓN: los pacientes sometidos a reconstrucción de LCA y slope tibial aumentado tienen un resultado funcional inferior al año de seguimiento evaluado por IKDC en comparación con pacientes con slope tibial dentro de parámetros normales.

INTRODUCTION: Total knee arthroplasty (TKA) is one of the most successful orthopedic treatments, however, it has been associated with severe postsurgical pain in 30-60% of patients. We propose that infiltration of the articular capsule of the knee during surgery will decrease postsurgical pain. MATERIAL AND METHODS: Experimental, randomized, double-blind study in patients undergoing unilateral TKA between April 2018 and January 2019. Patients were divided into two groups, the first infiltration with placebo and the second with anesthetic solution and adjuvants (fentanyl, epinephrine and ketorolac). Pain was measured with the visual analog scale (VAS) at 4, 6, 8, 12, 18, 24, 36 and 48 hours postsurgical, as well as the consumption of opioid analgesics and antiemetics. RESULTS: 20 patients in each group, with a follow-up of 4 weeks. There were no significant differences in demographic characteristics between the two groups. Better control of postsurgical pain was observed in the group that received infiltration with anesthetic and adjuvant, as well as a decrease in the consumption of opioid analgesics and antiemetics. There was no difference in bleeding or in the incidence of infections between the two groups. CONCLUSION: Peri-capsular infiltration is a safe and effective method, as part of multimodal analgesia in total knee arthroplasty, as it decreases postsurgical pain, opioid and antiemetic use and does not increase postsurgical bleeding.
INTRODUCCIÓN: La artroplastía total de rodilla (ATR) es uno de los tratamientos ortopédicos más exitosos; sin embargo, se ha asociado a dolor postquirúrgico intenso en 30-60% de los pacientes. Nosotros planteamos que la infiltración de la cápsula articular de la rodilla durante la cirugía disminuirá el dolor postquirúrgico. MATERIAL Y MÉTODOS: Estudio experimental, aleatorio, doble ciego, en pacientes sometidos a ATR unilateral entre Abril de 2018 a Enero de 2019. Los pacientes fueron divididos en dos grupos, el primero infiltración con placebo y el segundo con solución anestésica y adyuvantes (fentanilo, epinefrina y ketorolaco). Se cuantificó mediante escala visual análoga (EVA) del dolor a las cuatro, seis, ocho, 12, 18, 24, 36 y 48 horas postquirúrgicas, así como del consumo de analgésicos opioides y antieméticos. RESULTADOS: Veinte pacientes en cada grupo, con un seguimiento de cuatro semanas. No hubo diferencias significativas en las características demográficas entre ambos grupos. Se observó un mejor control del dolor postquirúrgico en el grupo que recibió infiltración con anestésico y adyuvante, además de una disminución en el consumo de analgésicos opioides y antieméticos. No hubo diferencia en sangrado ni en la incidencia de infecciones entre ambos grupos. CONCLUSIÓN: La infiltración pericapsular es un método seguro y eficaz, como parte de la analgesia multimodal en la artroplastía total de rodilla, ya que disminuye el dolor postquirúrgico, el consumo de opioides y antieméticos y no incrementa el sangrado postquirúrgico.

BACKGROUND: COVID-19 pandemic causes high global morbidity and mortality and better medical treatments to reduce mortality are needed. OBJECTIVE: To determine the added benefit of cyclosporine A (CsA), to low-dose steroid treatment, in patients with COVID-19. METHODS: Open-label, non randomized pilot study of patients with confirmed infection of SARS-CoV-2 hospitalized from April to May 2020 at a single centre in Puebla, Mexico. Patients were assigned to receive either steroids or CsA plus steroids. Pneumonia severity was assessed by clinical, laboratory, and lung tomography. The death rate was evaluated at 28 days. RESULTS: A total of 209 adult patients were studied, 105 received CsA plus steroids (age 55.3 ± 13.3; 69% men), and 104 steroids alone (age 54.06 ± 13.8; 61% men). All patients received clarithromycin, enoxaparin and methylprednisolone or prednisone up to 10 days. Patient's death was associated with hypertension (RR = 3.5) and diabetes (RR = 2.3). Mortality was 22 and 35% for CsA and control groups (P = 0.02), respectively, for all patients, and 24 and 48.5% for patients with moderate to severe disease (P = 0.001). Higher cumulative clinical improvement was seen for the CsA group (Nelson Aalen curve, P = 0.001, log-rank test) in moderate to severe patients. The Cox proportional hazard analysis showed the highest HR improvement value of 2.15 (1.39-3.34, 95%CI, P = 0.0005) for CsA treatment in moderate to severe patients, and HR = 1.95 (1.35-2.83, 95%CI, P = 0.0003) for all patients. CONCLUSION: CsA used as an adjuvant to steroid treatment for COVID-19 patients showed to improve outcomes and reduce mortality, mainly in those with moderate to severe disease. Further investigation through controlled clinical trials is warranted.

The importance of the immunomodulatory effects of vitamin D has recently been associated with autoimmune and chronic inflammatory diseases. Vitamin D deficiency has been linked to the development of autoimmune conditions. Antiphospholipid syndrome is an autoimmune disease characterized by thrombotic events and obstetric complications in patients with antiphospholipid antibodies. Current data show that patients with antiphospholipid syndrome have a high prevalence of vitamin D deficiency even without classic risk factors. Several studies have suggested vitamin D may have anti-thrombotic functions. In antiphospholipid syndrome, low vitamin D serum levels have been associated with thrombotic manifestations, suggesting a possible protective role of vitamin D in antiphospholipid syndrome. This literature review presents current evidence on the haemostatic functions of vitamin D and their possible relationship with the clinical manifestations of antiphospholipid syndrome.

We studied the epidemiologic triad-related factors influencing human papilloma virus (HPV) persistence in Mexican women with systemic lupus erythematosus (SLE). Patients aged ≥18 years with SLE (American College of Rheumatology criteria), with and without HPV persistence, were selected. Groups were analyzed by (1) host: clinical disease characteristics; (2) agent: (I) infectious (prevalence, incidence, HPV genotype and co-infections (≥2 HPV genotypes or mycoplasmas)), (II) chemical (contraceptives and immunosuppressive drugs) and (III) physical (vitamin D deficiency) and (3) environment. A total of 121 SLE patients were selected over a two-year period. (1) Host: mean age 45.8 years and disease duration 12.7 years. (2) Agent: (I) infectious. HPV infection prevalence in the second sample was 26.4%, high-risk HPV genotypes 21.5% and co-infections 7.4%. HPV infection incidence was 13.2%, persistence 13.2% and clearance 15.7%. (II) Chemical: use of oral hormonal contraceptives 5% and immunosuppressive treatment 97.5%. (III) Physical: Vitamin D levels were similar in both groups. (3) Environment: (I) natural. A total of 60.6% of patients were residents of Puebla City. (II) Social: The mean education level was 10.9. Poverty levels were: III degree 52.4%, IV degree 28% and II degree 17%. (III) Cultural behavioral: Onset of sexual life was 20.5 years, 10% had ≥3 sexual partners and 51.2% were postmenopausal. In conclusion, no factor of the epidemiologic triad was associated with HPV infection prevalence.

BACKGROUND: With the availability of high-quality asthma guidelines worldwide, one possible approach of developing a valid guideline, without re-working the evidence, already analysed by major guidelines, is the ADAPTE approach, as was used for the development of National Guidelines on asthma. METHODS: The guidelines development group (GDG) covered a broad range of experts from medical specialities, primary care physicians and methodologists. The core group of the GDG searched the literature for asthma guidelines 2005 onward, and analysed the 11 best guidelines with AGREE-II to select three mother guidelines. Key clinical questions were formulated covering each step of the asthma management. RESULTS: The selected mother guidelines are British Thoracic Society (BTS), GINA and GEMA 2015. Responses to the questions were formulated according to the evidence in the mother guidelines. Recommendations or suggestions were made for asthma treatment in Mexico by the core group, and adjusted during several rounds of a Delphi process, taking into account: 1. Evidence; 2. Safety; 3. Cost; 4. Patient preference - all these set against the background of the local reality. Here the detailed analysis of the evidence present in BTS/GINA/GEMA sections on prevention and diagnosis in paediatric asthma are presented for three age-groups: children with asthma ≤5 years, 6-11 years and ≥12 years. CONCLUSIONS: For the prevention and diagnosis sections, applying the AGREE-II method is useful to develop a scientifically-sustained document, adjusted to the local reality per country, as is the Mexican Guideline on Asthma.

Objective (a) to assess the prevalence of functional gastrointestinal disorders (FGIDs) in female Mexican systemic lupus erythematosus (SLE) patients using the Rome III criteria and (b) to examine the effect of disease duration on FGID prevalence. Methods Female SLE outpatients aged ≥18 years with no organic gastrointestinal disorder were included. Participants were invited to upper gastrointestinal endoscopy screening and a faecal immunochemical test. FGID symptoms were evaluated using the Rome III questionnaire. Results Eighty-six SLE patients with median age of 45 (interquartile range 34-54) years were included. At least one FGID was found in 76.7% (66/88) of patients with SLE. The most prevalent domains of FGID diagnosed were functional oesophageal, gastroduodenal disorders and bowel disorders, of which functional dyspepsia (72.7%), functional heartburn (68.1%) and bloating (63.8%) were the most frequent. Fifty-nine per cent of patients had overlapping FGIDs. The most prevalent overlap was the combination of functional dyspepsia and functional heartburn. Patients with longer disease duration had a higher prevalence of FGID than those with shorter disease duration. Conclusions There was a high prevalence of FGIDs in Mexican SLE women with low disease activity. Overlapping FGIDs were frequent. Longer disease duration may be associated with FGIDs in SLE patients.

Catastrophic antiphospholipid syndrome (CAPS), also called "Asherson syndrome", is a variant of the antiphospholipid syndrome (APS) that occurs in less than 1% of APS cases. The etiology of CAPS is uncertain; however, several triggering factors have been recognized. The most common of these are infectious diseases, particularly those of the respiratory tract. CAPS pathogenesis is incompletely understood, but several theories have been proposed, such as the molecular mimicry theory, which describes the production of anti-ß2-glycoprotein I (GP1) antibody in response to infection. The process is complex and involves the activation of Toll-like receptor 4 (TLR-4), which triggers a cytokine storm, followed by endothelial alterations that induce a procoagulant state.
