RESUMEN
Non-infectious uveitis, an autoimmune disease that can cause severe visual impairment, can be difficult to treat. According to the prevailing hypothesis, the immune-mediated imbalance that contributes to non-infectious uveitis is primarily driven by CD4+T cells. However, recent research has shown that B cells also play a significant role in this process, participating in various ways such as antibody production, antigen presentation, and cytokine secretion in both human uveitis and experimental autoimmune uveitis models. Therapies targeting B cells have been used extensively in various autoimmune diseases. Rituximab, a B-cell inhibitor, is effective in treating noninfectious uveitis that is unresponsive to conventional corticosteroid and immunosuppressive therapy. This paper provides an overview of the involvement of B cells in non-infectious uveitis and their potential use in cellular therapies, aiming to further investigate the mechanisms and develop more effective strategies for prevention and treatment.
RESUMEN
@#Introduction: Kawasaki disease (KD) is an acute febrile illness of unknown etiology that primarily affects children younger than 5 years of age. The diagnosis is predominantly clinical and at times difficult, due to the absence of any confirmatory and specific diagnostic test. Early diagnosis of this disease is of paramount importance due to long term cardiovascular complications related to coronary artery aneurysm. Literature search has revealed many atypical presentations of Kawasaki disease not fulfilling the clinical diagnostic criteria. The reason for this could be the diversity in clinical manifestations involving gastrointestinal, endocrinal, musculoskeletal and nervous system. Case Series: Here we describe three cases with non-classic presentation of Kawasaki disease. These three cases presented with persistent fever unresponsive to antibiotics. Two cases (case one and three) later developed perianal rash and peeling that helped in early diagnosis. In the remaining case (case two) sequential appearance of features helped in the establishment of diagnosis. It was interesting to note that all the three cases were having identical laboratory parameters, highlighting the importance of laboratory investigations in case of atypical presentation. Conclusion: This case series culminates the importance of keeping the possibility of atypical Kawasaki disease (KD) as one of the differentials in patients with prolonged fever not responding to antibiotics, in the absence of classical diagnostic criteria.
RESUMEN
@#Uveitis is a clinically common refractory blinding eye disease with complicated etiology and pathogenesis that is difficult to treat and prone to recurrence. It is currently considered to be closely associated autoimmune inflammatory response. Tumor necrosis factor-α(TNF-α)acts as a key pro-inflammatory factor in development and progression of uveitis. Adalimumab(ADA)is a fully humanized recombinant anti-immunoglobulin monoclonal antibody targeting TNF-α, and exerts its biological effects by specifically binding to TNF-α and blocking its binding to tumor necrosis factor receptors(TNFR-1/TNFR-2). This paper reviews the clinical research progress on the mechanism, efficacy and safety of ADA in the treatment of non-infectious uveitis.
RESUMEN
@#AIM:To evaluate the efficacy and safety of dexamethasone intravitreal implant for the treatment of noninfectious refractory uveitis and analyze its influence on application and dose of systemic corticosteroids and immunosuppressive agent.<p>METHODS: This was a retrospective, case series study conducted between January 2018 and September 2019, the patients with noninfectious refractory uveitis and treated with intravitreal implantation of dexamethasone intravitreal implant were included. The best corrected visual acuity(BCVA), central retinal thickness(CRT), vitreous haze score, and intraocular pressure(IOP)at 1mo, 2mo, 4mo and 6mo after the implantation of dexamethasone intravitreal implant were compared with the baseline. Meanwhile, the dosage of corticosteroids and immunosuppressive agent used before and after the implantation of dexamethasone was also evaluated. The data was displayed as mean±standard deviation and analyzed using the paired <i>t</i>-test.<p>RESULTS: A total of 19 patients(21 eyes)were included in the present study. The mean baseline BCVA of the included patients was 0.671±0.469, while the mean CRT was 369.667±177.100μm, and the mean intraocular pressure(IOP)was 14.252±3.181mmHg. One month, 2mo, 4mo and 6mo after the injection of Ozrudex, BCVA was significantly improved compared with the baseline(<i>P</i><0.05), while the CRT and vitreous haze score were significantly reduced(<i>P</i><0.05,<i> P</i><0.05). During the follow-up period, IOP of several patients significantly increased, but normal IOP can be observed at the end of the follow-up for all included patients. At baseline, 6 patients(6 eyes)were treated with systemic corticosteroids with an average dosage of 35.8mg/d, while only 2 patients were treated with systemic corticosteroids at the end of the 6mo follow-up(5mg/d). Apart from 3 eyes with Behcet's disease which showed recurrence of macular edema between 4-6mo, no other patient underwent that. <p>CONCLUSION: Dexamethasone intravitreal implantis considered to be a safe and effective approach for non-infectious refractory uveitis which can reduce systemic medication, with significant improvement of BCVA, reduction of CRT, vitreous haze score and the dosage of systemic corticosteroids.
RESUMEN
Background: Management of critically ill children poses a great challenge to the treating physician. With the advances in themanagement of critically ill children, there is an increased survival of critically ill children. Profile of mortality in the pediatricintensive care unit (PICU) varies between different age groups and between different studies. Childhood mortality is an importantindicator of health status of a country.Objective: The objective of the study was to study the pattern of mortality in a PICU.Materials and Methods: It is a retrospective study done at a tertiary care hospital. PICU records of all deaths were analyzedfrom January 2018 to December 2018.Results: Of 1993 admissions, there were 209 deaths. The mortality rate was 10.52%. One-hundred and nine children died dueto infections and 100 children died due to non-infectious causes.Conclusion: Overall infections were the major cause of death in children which are higher than the developed countries.Infections were the major cause of death in children under 5 years of age. In children older than 5 years, non-infectious causeswere the major cause of death. Mortality can be further reduced by improving infrastructure.
RESUMEN
@#Macular edema(ME)is a typical non-specific complication of uveitis, one of the common causes of visual impairment in patients with non-infectious uveitis(NIU). The treatment of uveitis related ME is still challenging in clinic. Various agents, such as corticosteroids, anti-vascular endothelial growth factors, and immune-modulators, have been used for combating uveitis related ME. However, there is not enough evidence to support the efficacy of any of these agents. Intravitreal dexamethasone implant(IDI, Ozurdex©; Allergan Inc, Irvine, CA)is a widely administered corticosteroid for the long-term management of uveitic ME in certain cases. Recent studies have demonstrated that IDI effectively improves uveitis related ME, and this effect could be sustained for at least six months with close monitoring and retreatment, as needed. Currently, we reviewed major clinical studies about IDI in eyes with NIU and briefly overviewed their results.

The samples were collected for both histopathology as well as for bacterial isolation. Gross and histopathological studies revealed variable histopathological changes such as congestion, haemorrhage, fatty changes and necrosis (Centrilobular and panlobular) in the liver. Kidneys showed haemorrhages, nephrosis, fatty changes, necrosis, atrophy of glomeruli
RESUMEN
Background: Febrile illness in elderly patients in hospitals is a challenge to the physician for diagnosis and treatment due to high morbidity as well as mortality and it increases if the febrile illness is prolonged. So proper evaluation and effective management is necessary for a better outcome. Keeping in mind the scarcity of studies in elderly febrile illness in India this study was taken up.Method: A prospective study was designed in medical ICU of S.C.B Medical college and Hospital, Cuttack Odisha, India. 50 patients were included in this study from July 2007 to December 2008. Institutional Ethics Committee cleared the study.Results: In 50 elderly (Age>60 yrs) patients of prolonged febrile illness, 36 (72%) were male and 14 (28%) were female. All had fever for >21 days. Pallor was the commonest sign (62%). 30 patients had infectious etiology, 15 had malignancies. Tuberculosis was the commonest infection (28%) comprising of 46.66% of infectious etiology with Pulmonary Tuberculosis (PTB) in 20% and Extrapulmonary Tuberculosis (ETB) in 26.66%. Malignancies accounted for 30% of cases with Non-Hodgkin’s lymphoma (NHL) in 33.33% being the commonest amongst the malignancies. On follow up of 50 patients 21 (42%) got cured.Conclusion: Febrile illness in elderly needs carefully evaluation as infections account for most of the cases and Tuberculosis in our part of India as a major cause in these patients is treatable. Malignancies remain the second most common cause where timely intervention goes a long way in reducing morbidity and mortality.
RESUMEN
Introduction: Patients with end-stage renal disease (ESRD) are treated with hemodialysis (HD) or continuous ambulatory peritoneal dialysis (CAPD).Non-infectious complications of CAPD are increasing in relative importance due to success in decreasing the rate of peritonitis. Aims and objectives: Our aim was to study the non-infectious complications in patients of ESRD on CAPD and to study the impact of the non-infectious complications in the survival of CAPD catheters. Materials and Methods: A prospective study has been conducted at Regional institute of medical science, Imphal in a total of 71patients of ESRD who are already on CAPD or newly diagnosed ESRD who have undergone CAPD catheter implantation. Their detailed history, clinical examination and relevant laboratory investigations were done and the different non-infectious complications were identified and analysed. Result: Out of the 71 patients studied 39 patients had complications like hypokalemia (15 patients), omental wrap (10 patients), catheter tip migration (6 patients), haemoperitonium (2 patients), hydrothorax (2patients), exit site leak(2patients), abdominal wall edema (1patient), catheter block(1patient). Conclusion: In our study the most common non-infectious complication was hypokalemia followed by omental wrap and catheter tip migration. Knowledge about the common prevalent non-infectious complications of CAPD alerts the treating doctor to take up the specific corrective steps at an earlier stage, thus preventing the morbidity associated with the same. We conclude that the majority of non-infectious complications in these patients were treatable and did not interfere with the catheter survival.
RESUMEN
Hepatocellular carcinoma (HCC) is a major disease with a high degree of malignancy, and poor prognosis, which seriously endangers human health. Chronic viral hepatitis (HBV, HCV)-cirrhosis-liver cancer patterns of pathogenesis has been widely accepted. However, the relationship between non-infectious liver disease and HCC is not completely clear; thereby how various non-infectious liver diseases develop through precancerous lesions has attracted widespread attention to HCC. A full understanding of these precancerous lesions is likely to provide new ideas and strategies for the prevention and treatment of non-infectious liver disease-related HCC.
RESUMEN
@#Dexamethasone intravitreal implant is a biodegradable dexamethasone(DEX)0.7mg slow-release implant that progressively dissolves in the vitreous gel. DEX implant now is approved for macular edema(ME)secondary to retinal vein occlusion(RVO), diabetic macular edema(DME)and non-infectious uveitis(NIU). The most common treatment-emergent adverse events are intraocular pressure(IOP)elevation and cataract. Therefore, DEX implant is still second choice level in treatment of RVO-ME and DME. It is reasonable to switch to DEX implant when anti-vascular endothelial growth factor(VEGF)therapy fail. However, DEX implant may be recommended as a first choice for selected cases, such as for pseudophakic eyes, anti-VEGF-resistant eyes, or patients reluctant to receive intravitreal injections frequently. Recent studies suggest dexamethasone implant is safely and effectively improves uveitis-related ME but the role of DEX implant in the management of NIU has yet to be defined. This article reviews the recent progress of DEX implant and focusing on its efficacy and safety.
RESUMEN
@#Uveitis has been generally defined as the inflammation occurring in the intraocular tissues. Among them, non-infectious uveitis is a T cell-mediated autoimmune inflammatory response. Through systemic treatments for non-infectious uveitis are abundant, the main principle is to suppress the immune response. In this review, we reviewed the history of non-infectious uveitis systemic therapy, detailed the current status of systemic treatment, summarized the pros and cons of each treatment regimen, and expected some new treatments for non-infectious uveitis.
RESUMEN
Resumen La fiebre es un signo común en la unidad de cuidados intensivos; implica el reto de descubrir su causa, por lo general refleja la existencia de infección, aunque puede tener origen no infeccioso o estar condicionada por síndromes de hipertermia. La Sociedad Americana de Enfermedades Infecciosas (IDSA, por sus siglas en inglés) y el Colegio Americano de Medicina en Cuidados Críticos definen la fiebre en pacientes críticamente enfermos como la temperatura igual o mayor a 38.3oC. La fiebre es una reacción fisiológica compleja de alguna enfermedad, mediada por el incremento de las citocinas y la generación de reactantes de fase aguda. Existen diferentes métodos para medir la temperatura y los médicos debemos saber el grado de precisión y las limitaciones de cada uno de ellos. En la unidad de cuidados intensivos, la temperatura corporal puede medirse mediante diversas técnicas, entre las que el catéter en la arteria pulmonar se considera el patrón de referencia. La fiebre en los pacientes críticamente enfermos puede clasificarse en tres categorías principales: síndromes de hipertermia, origen infeccioso y no infeccioso. Un episodio de temperatura mayor o igual a 38.3oC debe evaluarse. La historia clínica, el examen físico y las características de la fiebre (magnitud, duración, frecuencia y su relación con intervenciones diagnósticas o terapéuticas) son imprescindibles. Existe controversia en relación con el tratamiento de la fiebre; la evidencia actual le otorga un papel dual y opuesto, beneficios y perjuicios, de acuerdo con cada situación.
Abstract Fever is a common sign in the intensive care unit, this involves the challenge of discovering its cause, usually reflects the presence of infection, but may have no infectious origin or be conditioned by hyperthermia syndromes. The Infectious Diseases Society of America (IDSA) and the American College of Critical Care Medicine define fever in critically ill patients as temperature equal or greater than 38.3°C. Fever is a complex physiological reaction to a disease mediated increase of cytokines and generation of acute phase reactants. There are different methods to measure temperature; physicians should know the degree of accuracy and limitations of each. In the intensive care unit body temperature can be measured using different techniques among which the catheter in the pulmonary artery is considered the gold standard. Fever in critically ill patients can be classified into three main categories: hyperthermia syndromes, infectious origin and noninfectious. An episode of greater than or equal to 38.3°C temperature should be evaluated. The clinical history, physical examination and characteristics of fever (magnitude, duration, frequency and its relation to diagnostic or therapeutic interventions) are essential. There is controversy regarding the treatment of fever, current evidence gives a dual and opposite, benefits and harms, role depending on the situation.
RESUMEN
Objective To explore causes of fever in patients after the surgery for congenital heart disease(CHD), and put forward corresponding prevention and control measures.Methods Clinical data of patients undergoing sur-gery for CHD in the department of pediatric surgery of a hospital between January and May 2013 were analyzed ret-rospectively,the whole process of operation and postoperative nursing were observed,environmental hygiene moni-toring was performed at the same time.Results 26 patients all had fever after operation,fever in 21 cases (80.77%)was caused by non-infectious factors,5(19.23%)by infectious factors (ventilator-associated pneumonia in 4 cases,type I incision infection in 1 case).6 cases were absorption fever,20 were abnormal fever,difference in patients’age,duration of invasive manipulation (ventilator,urinary catheter,gastric tube)between two groups of patients were all statistically significant (all P <0.05),patients in the absorption fever group were with older age and short invasive manipulation time.Bacteriological detection rate in 26 patients was 76.92% (n=20),a total of 58 specimens were detected,7 were positive (from sputum specimens of 4 patients),5 isolates (71 .43%)were Pseudomonas aeruginosa .A total of 52 environmental specimens were collected for detection,the qualified rate was 80.77% (n =42).Conclusion Non-infectious factors are the main causes of postoperative fever in patients with CHD,health care workers should enhance the awareness of sterilization,standardize all kinds of medical manipula-tion,and reduce postoperative fever.
RESUMEN
This study was aimed to observe the clinical efficacy of Highly Active Antiretroviral Therapy (HAART) combined withPing-Ai(PA) Mixture in the treatment of Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome (HIV/AIDS) patients with non-infectious skin lesions, in order to study the advantages of integrative medicine in AIDS prevention and treatment. A total of 9 cases, who met the inclusion criteria of AIDS-associated non-infectious skin lesion with the pattern ofqi-yin deficiency and internal obstruction of phlegm-stasis, were selected. The combination of HAART and number 1 and 4 prescription of PA Mixture were used in the treatment for 3 months. The observations were made on changes of clinical symptoms, body signs, Karovsky integral and CD4+ T cells of patients before and after treatment. Stata 12.0 was used in the statistical analysis. The results showed that after integrative therapy, the single integral of clinical symptoms and body signs, such as skin spot papula, subcutaneous nodules, skin itching, fatigue was obviously reduced compared to that of the pretreatment. The total score decreased than that of the pretreatment. The patients’ quality of life (QOL) significantly increased. The Karovsky integral increased compared with that of pretreatment. The CD4+ T cells values were higher than that of the pretreatment. It was concluded that the integrative therapy had a certain effect in the treatment of AIDS-associated non-infectious skin lesions, which can improve the clinical symptoms, body signs, obviously increase the patients’ QOL and immune function.
RESUMEN
Skin rashes that appear during febrile illnesses are in fact caused by various infectious diseases. Since infectious exanthematous diseases range from mild infections that disappear naturally to severe infectious diseases, focus on and basic knowledge of these diseases is very important. But, these include non-infectious diseases, so that comprehensive knowledge of these other diseases is required. Usually, early diagnostic testing for a febrile illness with a rash is inefficient. For clinical diagnosis of diseases accompanied by skin rash and fever, a complete history must be taken, including recent travel, contact with animals, medications, and exposure to forests and other natural environments. In addition, time of onset of symptoms and the characteristics of the rash itself (morphology, location, distribution) could be helpful in the clinical diagnosis. It is also critical to understand the patient's history of specific underlying diseases. However, diagnostic basic tests could be helpful in diagnosis if they are repeated and the clinical course is monitored. Generally, skin rashes are nonspecific and self-limited. Therefore, it could be clinically meaningful as a characteristic diagnostic finding in a very small subset of specific diseases.

Objective:To explore the participation of clinical pharmacists in drug treatment. Methods:Clinical pharmacists car-ried out pharmaceutical ward round, and understood the medication history of one breast cancer patient with postoperative pneumonia. They thought the induction possibility of trastuzumab likely to be non infectious pulmonary infiltration. Combined with the drug instruc-tions, relevant literatures and case report, they put forward suggestions for the medication, and participated in the formulation of drug therapy. Results:The suggestions of clinical pharmacists were adopted, and on the second day of methylprednisolone sodium succinate treatment, the symptoms of the patient were improved, and the results of the imaging examination also tended to be improved without recurrence. Conclusion:The participation of clinical pharmacists in the formulation of clinical medication has important significance for improving the level of clinical treatment.
RESUMEN
Background: Various environmental, socio-economic and geographical factors influence the pattern of dermatoses in an area. Observations made at tertiary dermatology centres may not reflect the actual pattern of dermatoses at the community level. Aims: To evaluate the pattern of dermatoses at community level and compare it with that at a tertiary centre. Methods: Cases were registered through community visits in block Hazratbal in Kashmir valley, once a week over a calendar year. The pattern of dermatoses observed was compared with that seen at the tertiary centre over the same period. Results: A total of 1065 community cases, with 1105 dermatoses, were compared with 4358 patients with 4466 dermatoses seen at the tertiary centre. Non-infectious dermatoses in each group were more common than infectious dermatoses (34.08% infectious dermatoses versus 65.97% non-infectious in community cases and 29.42% infectious dermatoses versus 70.58% non-infectious in hospital patients). Infectious cases were seen significantly more in the community (34.08%) than at the tertiary centre (29.42%). Among the infectious diseases, fungal infection was the most common and in the non-infectious group, pigmentary disorders were the most common, followed by acne and eczema. Conclusion : Infectious dermatoses were found statistically significantly more in community cases as compared to hospital patients while the opposite was the case with non-infectious dermatoses. The study emphasizes the need for providing frequent dermatology services to the community at the primary healthcare level so that the burden of dermatoses, especially infectious, may be reduced. Also, wider studies should be conducted in different regions in order to assess the actual magnitude of dermatological illnesses in the community.

The International Health Regulations (IHR 1969), replaced by IHR 2005 had been adopted by the World Health Assembly on 23 May 2005 and came into force on 15 June 2007. IHR 2005 are a legally binding agreement among World Health Organisation (WHO) member states and other states that have agreed to be bound by them. New revision was necessitated by concerns about increasing global health threats and the need to respond with more effective surveillance and control practices. The limitations of IHR 1969, which led to their revision, related to their narrow scope, their dependence on official country notifications, and their lack of a formal internationally coordinated mechanism to contain international disease spread. The IHR 2005, which is firmly based on practical experiences, has broaden the scope of IHR 1969 to cover existing, new and re-emerging diseases, including emergencies caused by non-infectious disease agents.
RESUMEN
La incidencia de fiebre en el postoperatorio varía ampliamente. En la cirugía limpia y la limpia-contaminada, la fiebre no infecciosa es más frecuente que la infecciosa. Fueron estudiados prospectivamente 303 pacientes operados en forma programada de cirugía ortopédica y urológica. Se investigó la incidencia de fiebre postoperatoria, su etiología, la relación entre el momento de su aparición y su origen y la utilidad del pedido empírico de estudios para determinar infección postoperatoria. El 14% (42/303) de los pacientes tuvieron fiebre postoperatoria. En el 81% (34/42) su etiología fue no infecciosa y en el 19% (8/42) infecciosa. Su origen fue siempre no infeccioso dentro de las primeras 48 horas del postoperatorio (p<0.001). A 19 pacientes con fiebre después de las 48 horas y examen clínico normal, se les realizó radiografía de tórax, hemocultivos (2) y cultivo de orina. Las radiografías de tórax fueron normales en todos los casos, fueron positivos 4 urocultivos (21%, IC 95%: 6-45) y un hemocultivo (5%, IC 95%: 0.1-26). Siete pacientes tuvieron infecciones postoperatorias sin fiebre. La causa de fiebre postoperatoria más frecuente fue no infecciosa, causada por respuesta normal inflamatoria al trauma quirúrgico. La realización de estudios de rutina en pacientes con examen clínico normal y fiebre posterior a las 48 horas, de acuerdo a lo observado en este estudio, no permite sacar conclusiones definitivas. El diagnóstico de las infecciones postoperatorias se basó en el seguimiento clínico- quirúrgico y en la interpretación de los síntomas y signos del paciente.
Post-operative fever incidence varies widely. In clean and clean-contaminated surgery the non-infectious fever is more frequent than the infectious fever. We performed a prospective study including 303 patients who underwent orthopedic and urologic elective surgery. The aims of our study were to investigate the incidence of post-operative fever, its etiology, the relationship between time of onset and the etiology, and the usefulness of extensive fever work-up to determine post-operative infection. The incidence of post-operative fever was 14% (42/303) of which 81% (34/42) was noninfectious and 19% (8/42) was infectious. The etiology of the fever in the first 48 hours after surgery was always non-infectious (p<0.001). An extensive fever work-up was performed in patients who presented fever only after the initial 48 hours of surgery with normal physical examination (n=19) consisting of chest x-ray, blood (2) and urine cultures. The chest x-ray was normal in all the patients, the urine cultures were positive in four cases (21%, IC 95%: 6-45) and the blood cultures in only one case (5%, IC 95%: 0.1-26). Seven patients had post-operative infections without fever as a clinical sign. The most frequently observed etiology of post-operative fever was non-infectious, related to the normal inflammatory host response to surgery. Based on the present results, the extensive fever work-up performed to investigate post-operative infection does not seem to be a useful tool. The diagnosis of post-operative infection was based on clinical follow up and the correct interpretation of the patient's symptoms and signs.
