Differences of resting-state percent amplitude of fluctuations among migraineurs without aura with different efficacy of non-steroidal anti-inflammatory drugs / 中华行为医学与脑科学杂志

Objective:To explore the differences of resting-state spontaneous neural activity between migraine without aura (MwoA) patients with response or nonresponse to non-steroidal anti-inflammatory drugs (NSAIDs), and its correlation with migraine-related features.Methods:From February 2021 to April 2022, thirty MwoA patients with response to NSAIDs, 30 MwoA patients with nonresponse to NSAIDs, and 30 healthy controls were recruited in the Affiliated Jiangning Hospital of Nanjing Medical University.All subjects were scanned with a 3.0 T resting-state functional magnetic resonance imaging scanner.The percent amplitude of fluctuation (perAF) approach was used to calculate the differences of the resting state brain functional activities among the three groups (Bonferroni multiple comparison correction). SPSS 24.0 software and RESTplus software were used for statistical analysis.Analysis of variance was used for the perAF values of three groups.Correlation analysis was performed between perAF values of brain regions with significant differences and migraine-related features.Results:The brain areas showing significant differences of perAF among the three groups located in the left anterior cingulate cortex (ACC)( x, y, z = -6, 9, -3), left middle frontal gyrus (MFG)( x, y, z =-39, 48, 9) and left middle temporal gyrus (MTG)( x, y, z = -57, -30, -15)(all P<0.05, Bonferroni correction). Compared with nonresponse group, the perAF in response group showed significant decreased in the left ACC, MFG and MTG.There was positive correlation between the perAF of left ACC and disease duration ( r=0.506, P=0.007). Compared with healthy controls, the perAF of nonresponse group showed increased in the left ACC, which was negatively correlated with frequency ( r=-0.414, P=0.032). Conclusion:The neural activity of prefrontal cortex and ACC may be the neuropathological basis underlying response to NSAIDs in MwoA treatment.Moreover, the ACC has certain correlations with migraine-related characteristics, which may serve as a potential neuroimaging biomarker to evaluate the efficacy of NSAIDs.

Drug-induced Stevens-Johnson syndrome: A case series

Stevens-Johnson syndrome (SJS) can be defined as a rare, serious disorder of the skin and mucous membrane characterized by widespread vesiculobullous rash with epidermal sloughing and necrosis involving mainly eyes, oral cavity, and skin. SJS can be diagnosed if there is <10% of the skin involvement. SJS occurs as an idiosyncratic reaction to various medications. Among them, the most common are antimicrobial agents (AMAs), antiepileptics, and non-steroidal anti-inflammatory drugs (NSAIDs). SJS is one of the dermatological emergencies for which initial treatment can only be supportive like fluids and nasogastric or parenteral feeding and symptomatic measures like analgesic mouth rinse for mouth ulcer. Beyond this, no treatment for SJS is approved. Cases of drug-induced SJS as diagnosed by Skin and VD department were included in the study. Interpretations were drawn out from that data and causality assessment was done according to the WHO-UMC causality assessment. Total four cases of drug-induced SJS were available. two cases of male patients and two of female patients. Out of them, three cases were by NSAIDs induced and one case was anti-epileptic (phenytoin) induced. In the present study, it was found that three of the cases of drug-induced SJS were caused NSAIDs and one case by anti-epileptic. According to the WHO-UMC Causality assessment, three cases were probable and one was unclassified.

A comparative analysis of topical corticosteroids and non-steroidal anti-inflammatory drugs to control inflammation and macular edema following uneventful phacoemulsification

Purpose: To compare the efficacy of topical nonsteroidal anti?inflammatory drugs (NSAIDs) and prednisolone acetate in controlling inflammation and preventing cystoid macular edema (CME) after uneventful phacoemulsification. Methods: All patients who underwent uneventful phacoemulsification from December 2020 to Feb 2021 were included in the study. These were randomly assigned to receive any one anti?inflammatory agent among topical nepafenac (0.1%) [96 eyes], bromfenac (0.07%) [93 eyes], preservative?free ketorolac (0.4%) [94 eyes], nepafenac (0.3%) [96 eyes], or prednisolone acetate (1%) [91 eyes]. The efficacy of the drugs was evaluated by comparing the grade of anterior chamber (AC) cells, conjunctival hyperemia, pain score, visual acuity, intraocular pressure (IOP), and central macular thickness (CMT) at 1 and 6 weeks after surgery. Results: At 1 and 6 weeks, there was no significant difference in pain score, conjunctival hyperemia, AC cells, change in IOP, and visual acuity between the prednisolone and the NSAIDs groups, though nepafenac 0.3% was most effective. At 6 weeks, there was no significant difference in the number of patients developing subclinical CME in the prednisolone versus NSAID group. The mean increase in CMT was significantly lower in nepafenac 0.3% than prednisolone at 1 and 6 weeks (P = 0.003 and 0.004, respectively). Conclusion: NSAIDs used in isolation are comparable to prednisolone in preventing inflammation and pain after uneventful phacoemulsification. However, nepafenac 0.3% is most comparable to prednisolone and more efficacious in reducing the incidence of CME. We recommend that nepafenac 0.3% can be used as a sole anti?inflammatory agent in patients with uneventful phacoemulsification.

Pay attention to the role of anti-inflammatory in the treatment of diabetic retinopathy / 中国医师杂志

Diabetic retinopathy (DR) is a retinal microvascular disease associated with diabetes which is the primary cause of impaired vision in working age population. Inflammatory reaction and inflammatory factors such as tumor necrosis factor-α (TNF-α) and interleukin (IL)-1β play an important role in the occurrence and development of DR, and to target at which anti-inflammatory treatments such as glucocorticoids and non-steroidal anti-inflammatory drugs were used, but with disputes on therapeutic effect and drug selection. This review aims to clarify the research on mechanism of inflammatory reaction in DR, summarize the application status of existing anti-inflammatory therapy, and provide some new ideas for the research and clinical application of the treatment of DR.

Solid Phase Extraction and Simultaneous Chromatographic Quantification of some Non-steroidal Anti-inflammatory Drug Residues; an Application in Pharmaceutical Industrial Wastewater Effluent

Abstract Two sensitive and selective methods were developed for the simultaneous determination of four commonly used non-steroidal anti-inflammatory drugs (NSAIDs), namely; paracetamol (PCM), diclofenac sodium (DCF), ibuprofen (IBP), and indomethacin (IND) in wastewater effluents. The first method used HPLC for the determination of the studied drugs using a mobile phase consisting of phosphate buffer (pH 3.0) and acetonitrile at a flow rate of 1 mL/min. in gradient elution mode and detection at 220 nm. The separation process was performed on BDS Hypersil Cyano column (250 x 4.6 mm, 5 µm). The second method was a TLC-densitometric one which was performed using n-Hexane: ethyl acetate: acetic acid in the ratio (6:3.5:0.5) as a developing system. The proposed chromatographic methods were successfully applied for the selective determination of the four studied drugs in simulated and real pharmaceutical wastewater samples after their solid-phase extraction

Erupção pigmentar fixa à nimesulida comprovada por teste de contato / Fixed pigmented erythema from nimesulide proven by patch testing

A erupção pigmentar fixa (EPF) é uma reação cutânea adversa a drogas relativamente comum, envolvendo cerca de 10% de todas as reações de hipersensibilidade a medicamentos (RHM). Envolve uma reação imunológica não imediata, mediada por células T CD8+ sensibilizadas, relacionada ao mecanismo do tipo IVc na classificação de Gell e Coombs. Um dos grupos mais frequentemente implicados nesse tipo de reação é o dos antiinflamatórios. Relatamos o caso de um homem que, 24 horas após iniciar tratamento com nimesulida para lombalgia, apresentou um quadro de lesões cutâneas tipo máculas eritemato-violáceas bem delimitadas e disseminadas pelo corpo. A nimesulida é um fármaco anti-inflamatório não esteroidal (AINE) pertencente à classe das sulfonanilidas, que atua como inibidor seletivo da enzima da síntese de prostaglandina, a ciclo-oxigenase, inibindo preferencialmente a COX-2. O diagnóstico foi comprovado pela realização do teste de contato, também conhecido como patch test, que traduziu positividade na segunda leitura realizada após 72 horas da sua colocação.

Fixed pigmented erythema (FPE) is a relatively common adverse drug reaction, consisting of approximately 10% of all drug hypersensitivity reactions. It involves a non-immediate immune reaction mediated by sensitized CD8+ T cells and related to the type IVc mechanism in the Gell-Coombs classification. One of the groups most frequently involved in this type of reaction is that of anti-inflammatory drugs. We report the case of a man who, 24 hours after starting treatment with nimesulide for low back pain, presented with well-defined cutaneous lesions consisting of erythematous-violaceous macules and spread throughout the body. Nimesulide is a non-steroidal anti-inflammatory drug (NSAID) belonging to the sulfonanilide class that acts as a selective inhibitor of the prostaglandin synthesis enzyme, cyclooxygenase (COX), preferentially inhibiting COX-2. The diagnosis was confirmed by a patch test, which translated positively in the second reading performed 72 hours after its placement.

Prescripción de analgésicos no opioides en un Servicio de Ortopedia / Prescription of non-opioid analgesics in an Orthopedics Service

Introducción: El dolor asociado a las alteraciones del sistema musculoesquelético debe ser tratado frecuentemente por los especialistas en Ortopedia. Los analgésicos no opioides se ubican dentro de los fármacos que más se prescriben en este Servicio, aunque no siempre de modo adecuado, según los principios de la prescripción racional. Objetivo: Caracterizar el uso de analgésicos no opioides en el servicio de Ortopedia del Hospital Dr. Salvador Allende. Material y Métodos: Estudio descriptivo de utilización de medicamentos del tipo prescripción-indicación y esquema terapéutico. Se revisaron las historias clínicas de 70 pacientes ingresados en el Servicio de Ortopedia del Hospital Dr. Salvador Allende, durante el período comprendido desde septiembre de 2018 hasta enero de 2019. Resultados: Predominó el sexo femenino y la media de edad de 71,3 años en los pacientes estudiados con una desviación estándar de 22.2 años. Los analgésicos más prescritos fueron dipirona, diclofenaco y paracetamol, en indicaciones aprobadas donde destacaron las fracturas, la celulitis y la seudoartrosis. En la totalidad de los casos, las dosis empleadas fueron adecuadas, no así los intervalos de administración ni la duración del tratamiento. Conclusiones: Es alentador el predominio de la prescripción de analgésicos no opioides con buena relación beneficio-riesgo. No obstante, la presencia de prescripciones irracionales en cuanto a intervalos de administración y duración del tratamiento, indica un déficit en la práctica de la terapéutica analgésica que no debe ser ignorado(AU)

Introduction: The pain associated with alterations of the musculoskeletal system should be frequently treated by the specialist in Orthopedics. Non-opioid analgesics are the most prescribed drugs in this medical service although they are not always used appropriately according to the principles of national prescription. Objective: To characterize the use of non-opioid analgesics in the orthopedics service of the Dr. Salvador Allende Hospital. Material and Methods: A descriptive study of the use of prescription-indication medications and therapeutic scheme was conducted. Medical records of 70 patients admitted to the orthopedics service of the Dr. Salvador Allende Hospital during the period between September 2018 and January 2019 were reviewed. Results: The female sex and a mean age of 71.3 years with standard deviation of 22,2 years predominated in the study. The most frequently used analgesics, which were indicated in the treatment of fractures, cellulitis and pseudarthrosis, were dipyrone, diclofenac and paracetamol. In all cases, the doses used were adequate, but not the administration intervals or the duration of treatment. Conclusions: The predominance of the prescription of non-opioid analgesics with a good benefit-risk ratio is encouraging. However, the presence of irrational prescriptions regarding administration intervals and duration of treatment indicates a deficit in analgesic therapy that should not be ignored(AU)

Objective To systematically evaluate the efficacy and safety of different non-steroidal anti-inflammatory drugs (NSAIDs) in middle-aged and old Chinese patients with osteoarthritis(OA). Methods A systematic literature search was conducted through PubMed, Cochrane Library, CNKI, Wan Fang Data and VIP databases to collect randomized controlled trials with non-steroidal anti-inflammatory drugs in middle-aged to old Chinese OA patients. The search time was from the establishment of the database to November 17, 2020. Two researchers independently carried out literature screening, data extraction and literature quality evaluation. Bayesian network meta-analysis was conducted with R3.6.0 software. Results 28 RCTs were included with 2531 patients. Based on the last follow-up pain visual analogue scale (VAS) score, the ranking chart showed that Etoricoxib had the highest probability of having the lowest pain VAS score (88.55%). In terms of total effective rate, the ranking chart showed that the probability of Etoricoxib as first choice was the highest (92.49%). As far as safety, diclofenac sodium patch had the lowest adverse effects rate (59.10%). Conclusion The results of this study indicated that Etoricoxib was the most effective treatment for middle-aged and old Chinese OA patients. It can significantly reduce the OA pain. Diclofenac sodium patch had the least adverse effects.

The predicting effect of disrupted functional connectivity of anterior cingulate cortex on the efficacy of nonsteroidal anti-inflammatory drugs in migraineurs without aura / 中华行为医学与脑科学杂志

Objective:To investigate the predicting effect of the disrupted functional connectivity of the anterior cingulate cortex (ACC) on the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) in patients with migraineurs without aura (MwoA).Methods:From January 2019 to January 2021, seventy patients with migraine and thirty-three healthy people in the same period were selected.The functional connectivity analysis based on the ACC was used in MwoA patients with NSAIDS-effective ( n=35), MwoA patients with NSAIDS-ineffective ( n=35), and healthy controls (HCs) ( n=33). The abnormal resting-state functional connectivity patterns among the three groups were analyzed to reveal potential correlations with clinical characteristics in migraine. Then the receiver operating characteristic (ROC) curve was used to analyze the predictive ability of the abnormal ACC functional connectivity on the efficacy of NSAIDs in patients with MwoA. Results:(1)Compared with the MwoA patients with NSAIDs-ineffective, the MwoA patients with NSAIDs-effective showed higher functional connectivity between bilateral ACC and left middle cingulate cortex (MCC) (MNI: x, y, z=0, -24, 48, cluster=14, t=3.380) and postcentral gyrus (PoCG)( MNI: x, y, z=-21, -45, 69, cluster=12, t=3.016) (all P<0.005, Bonferroni correction). Compared with the HCs, patients with MwoA showed increased functional connectivity between left ACC and ipsilateral inferior parietal lobule, middle frontal gyrus (MFG) and angular gyrus (AG), and between right ACC and right precuneus, bilateral MFG and left AG (all P<0.005, Bonferroni correction). (2)There was a positive correlation between the functional connectivity of right ACC to right precuneus and MIDAS scores ( r=0.375, P=0.035) in MwoA patients with NSAIDs-effective. In MwoA patients with NSAIDs-ineffective, there were also significant correlations between the functional connectivity of left ACC to ipsilateral AG and MFG and headache onset duration ( r=0.357, P=0.045) and disease duration ( r=-0.367, P=0.039). (3)ROC curve analysis showed that the area under the curve (AUC) for the functional connectivity between the right ACC and left MCC and between the left ACC and left PoCG to predict the efficacy of NSAIDs were 0.728 and 0.736, respectively. Conclusions:Resting-state functional connectivity of the ACC is involved in the evaluation and prediction for analgesic efficacy of NSAIDs in migraine patients, which provides neuroimaging evidence for further investigations on the neurophysiological mechanism of migraine and assistance in clinical individualized precise treatment.

Immediate postpartum intrauterine contraceptive device insertions in caesarean and vaginal deliveries: a comparative study

Background: Post-partum family planning is prevention of unintended and closely spaced pregnancies during first 12 months following childbirth. Postpartum IUCD is the best method of all as it is the safest, most effective, has no effect on breast feeding, reliable and with minimum complications.Methods: The cross-sectional study was conducted in AIMSR Bathinda on 400 postpartum patients. It was a prospective, observational study of women who received PPIUCD in our region.Results: Out of total 400, 58% had normal vaginal delivery and 42% had cesarean section. PPIUCD was done in all cases after applying exclusion criteria and the females were called for follow up.  53% cases who had cesarean and 47% of normal vaginal delivery turned up for follow up. Acceptance is more in multipara (20.7%) than in primi patients (13.7%). Almost 90% patients had good continuation rate. There were few problems faced by patients like irregular bleeding for first few months, pain lower abdomen, leucorrhea etc. which were removed by good counseling and some treatment like NSAIDs for bleeding.Conclusions: The acceptance of PPIUCD was high in present study in both types of females delivered by normal vaginal delivery or post LSCS but with good counseling efforts. It was safe and effective and had high retention rate when done at good timing by trained service provider that is within 10 minutes of placental delivery. So the need of time is creating awareness of public towards it and removing fear from minds, breaking taboos and myths.

Dentists knowledge about over the counter-NSAIDs: An emerging need for NSAID-avoidance education

Objectives of the study: Non-steroidal anti-inflammatory drugs (NSAIDs) belong to a group of drugs used in themanagement of pain. The aim of this study is to assess dentists’ knowledge of NSAIDs risks and to determine the mostprescribed NSAIDs by dentists.Materials and Methods: We collected information concerning the dentists’ knowledge of NSAIDs use and adverseeffects. A questionnaire consisting of 22 questions was distributed to 123 Albanian dentists reached in different dentalclinics, out of which only 87 agreed to participate. Only 70.73% of the distributed questionnaires were completed.Results: Respondents demonstrated poor knowledge of NSAIDs. Most of the respondents did not respond correctlyto the questions with 39.08% of incorrect answers regarding the implications of NSAIDs in elderly patients and only3.44% responded correctly to the contraindication of NSAIDs. The most common prescriptions were ketoprofen,ibuprofen, followed by ketorolac, aspirin, and diclofenac.Conclusions: Dentists who participated in the survey have limited knowledge of NSAIDs use, contraindication, andsafety limitation which can affect patients’ safety and well-being. Dentists should pay particular attention to informingpatients on NSAIDs use and should also keep updated on NSAIDs, through continuing education programs.

Indomethacin attenuates mechanical allodynia during the organization but not the maintenance of the peripheral neuropathic pain induced by nervus ischiadicus chronic constriction injury

The neurochemical mechanisms underlying neuropathic pain (NP) are related to peripheral and central sensitization caused by the release of inflammatory mediators in the peripheral damaged tissue and ectopic discharges from the injured nerve, leading to a hyperexcitable state of spinal dorsal horn neurons. The aim of this work was to clarify the role played by cyclooxygenase (COX) in the lesioned peripheral nerve in the development and maintenance of NP by evaluating at which moment the non-steroidal anti-inflammatory drug indomethacin, a non-selective COX inhibitor, attenuated mechanical allodynia after placing one loose ligature around the nervus ischiadicus, an adaptation of Bennett and Xie's model in rodents. NP was induced in male Wistar rats by subjecting them to chronic constriction injury (CCI) of the nervus ischiadicus, placing one loose ligature around the peripheral nerve, and a sham surgery (without CCI) was used as control. Indomethacin (2 mg/kg) or vehicle was intraperitoneally and acutely administered in each group of rats and at different time windows (1, 2, 4, 7, 14, 21, and 28 days) after the CCI or sham surgical procedures, followed by von Frey's test for 30 min. The data showed that indomethacin decreased the mechanical allodynia threshold of rats on the first, second, and fourth days after CCI (P<0.05). These findings suggested that inflammatory mechanisms are involved in the induction of NP and that COX-1 and COX-2 are involved in the induction but not in the maintenance of NP.

Effects of Different NSAIDs Combined with PICA on Postoperative Analgesia in Patients Undergoing Gynecolo- gical Laparoscopic Surgery and Its Effect on Serum Related Factors / 中国药房

OBJECTIVE：To investigate the effects of parecoxib sodium ，flurbiprofen axetil and lornoxicam combined with patient controlled intravenous analgesia （PICA） on postoperative analgesia in patients undergoing gynecological laparoscopic surgery and its effect on serum related factors. METHODS ：A total of 280 patients who underwent gynecologic laparoscopic surgery in the Second Affiliated Hospital of Hainan Medical University from Mar. 2017 to Mar. 2019 were randomly divided into control group （group C ），parecoxib sodium group （group P ），and flurbiprofen axetil group （group F ）and lornoxicam group （group L ）acording to random number table ，with 70 patients in each group. Four groups of patients received Sodium chloride injection 5 mL，Parecoxib sodium for injection 40 mg，Flurbiprofen axetil injection 50 mg and Lornoxicam for injection 8 mg （added 8 mg when the effect was not good ）intravenously at 30 min before the end of surgery. At the end of surgery ，they were given PICA of Sufentanil citrate injection and Dizosin injection for analgesia. The situation of pain and nausea symptom were evaluated at 6，12，24 and 48 h after surgery by using numerical rating scale （NRS）. The levels of serum CRP ，IL-6，SP and PGE 2 were detected by chemiluminescence method and ELISA. The times of pressing PICA pump and the dosage of analgesic were recorded in 4 groups within 24 h after surgery. The ADRs of patients within 48 h after surgery were recorded ，such as bloating ， dizziness，itchy skin ，respiratory depression and urinary retention. RESULTS ：At different time points ，the NRS scores of pain of group P ，F and L were significantly lower than those of group C ；and 48 h after surgery ，NRS score of pain of group L was significantly lower than those of group P and F （P＜0.05）. There was no statistical significance in the level of CRP ，IL-6，SP and PGE2 of 4 groups before surger （P＞0.05）. The CRP ，IL-6，SP and PGE 2 levels at each time point after surgery of group P ，F and L were significantly lower than those of group C ；compared with group P ，serum level of SP at 48 h after surgery as well as serum levels of PGE 2 at 12，24 and 48 h after surgery were significantly decreased in group F ，and serum level of IL- 6 at 48 h after surgery，serum levels of SP at 24 and 48 h after surgery ，serum levels of PGE 2 at 12，24，48 h after surgery were decreased significantly in group L ；compared with group F ，serum level of SP at 48 h after surgery as well as serum levels of PGE 2 at 12， 24，48 h after surgery were all decreased significantly in group L （P＜0.05）. There was no statistical significance in the incidence of anausea and vomiting among 4 groups（P＞0.05）. CONCLUSIONS ：Parecoxib sodium ，flurbiprofen axetil and lornoxicam combined with PICA can effectively relieve the pain of patients after gynecological laparoscopic surgery and reduce the levels of serum related factor ，and lornoxicam has the most obvious effect.

Self-medication practices of over the counter analgesics among first and third semester undergraduate medical students in a tertiary care medical college, Jharkhand

Background: Self-medication is a widely practiced trend in the general Indian population. Among the medical students, self- medication is popular because of awareness about the disease and their treatment. Analgesics are one of the most common drugs used for self-medication. Very few studies are available in Jharkhand regarding this subject. So, the present study aims to delve into the pattern of self-medication practices of analgesics among the 1st and 3rd semester medical students of RIMS, Ranchi, Jharkhand.Methods: A questionnaire based cross sectional study was done in RIMS, Ranchi, Jharkhand, India in March-April 2019 among the undergraduate medical students. The results were expressed as percentage and frequency.Results: Out of total 150 and 142 students in the 1st and 3rd semester respectively, 140 and 130 students practiced self- medication. Advice from seniors was the biggest source of information in both the groups followed by internet and books. Paracetamol was the most common drug (75%; 60%) and headache was the most common indication (55%; 68%). Quick relief of symptoms was the most common reason for self-medication in both the groups (44%; 48%).Conclusions: In both the groups, the students continued the drug even after experiencing side effects (77%; 60%). Most students were of the view that such practice is not acceptable at all times (75%; 72%).

To Evaluate the Therapeutic Efficacy of Vildagliptin on Microalbuminuria in Type 2 Diabetes Mellitus

Introduction: Diabetic kidney disease (DKD) representsone of the most frequent microvascular complications ofdiabetes with an overall prevalence of approximately 40% intype 2 diabetes population. Microalbuminuria is one of themost serious problems in type 2 DM. Vildagliptin, DPP-4inhibitors, is a novel oral anti-diabetic drug for the treatmentof type 2 diabetes mellitus (T2DM). The objective of the studywas to evaluate the therapeautic efficacy of vildagliptin onmicroalbuminuria in type 2 diabetes mellitus.Material and methods: We included in our study 103 T2DMpatients with microalbuminuria. Exclusion criteria: NSAIDsinduced nephropathy, Lupus nephropathy, Polycystic KidneyDisease, Medullary Sponge Kidney, All causes of nephriticand nephrotic syndrome, ESRD due to diabetes mellitus andmoderate to severe hepatic failure. We measured UrinaryACR value of parameters at 0,3.6,9,12 months respectively.Vildagliptin was given to those patient and was observed thatafter giving vildagliptin was there any change in albumin tocreatinine i.e microalbuminuria.Result: The mean of ACR baseline (mean±s.d.) of patientswas 125.1436 ± 58.810 with range 50.7000 - 298.0000 and themedian was 100.0000. The mean of ACR of 3, 6, 9, 12months(mean±s.d.) of patients were 110.3184 ± 57.5647, 106.7340 ±48.8492, 103.7252 ± 45.6745, 95.4466 ± 62.342 respectively.Association of ACR in five groups was not statisticallysignificant (p=0.6118).Conclusion: We found that after 12 months of therapy withvildagliptin, a DPP-4 inhibitor, there was some reduction ofACR and it is approximately 30%

Analgesia in intensive care unit: something truly counts / 中华危重病急救医学

Critical patients in the intensive care unit (ICU) are often accompanied with acute pain,which may lead to a series of physiological responses that affect the prognosis of patients.With the continuous advancement of modem medicine,the pain management strategies and analgesics have also greatly developed,and the concept has been continuously updated.In the individualized diagnosis and treatment mode,the pain management is an indispensable component of ICU comprehensive treatment.Multimodal analgesia (MMA) strategies have also shown to be effective in optimizing analgesia in critical patients.However,there are still many shortcomings and differences in pain evaluation and its management.The characteristics and methodologies of related analgesics need to be further summarized and discussed.The current literature about the evaluation of pain,pharmacology and non-pharmacological techniques were reviewed to provide references for the scientific and reasonable implementation of analgesia treatment in ICU.

Effectiveness of Platelet Function Analyzer-100 for Laboratory Detection of Anti-Platelet Drug-Induced Platelet Dysfunction

BACKGROUND: High on-treatment platelet reactivity (HTPR) is the phenomenon wherein patients exhibit normal platelet activity in laboratory testing despite adequate adherence to anti-platelet treatment. We investigated the detection rates of Platelet Function Analyzer (PFA)-100 (Dade Behring AG, Düdingen, Switzerland) for drug-induced platelet dysfunction and analyzed potential contributors to HTPR with practical PFA-100 data over six years. METHODS: We used data from 6,957 patients who underwent PFA-100 testing after receiving aspirin, clopidogrel, or non-steroidal anti-inflammatory drugs (NSAIDs). Of these, 6,163 patients were tested with only the collagen/epinephrine cartridge (Col/EPI) of PFA-100; 794 were tested with both Col/EPI and the collagen/ADP cartridge (Col/ADP). We calculated PFA-100 closure time (CT) for each drug and compared the clinical and laboratory characteristics of the patients with prolonged CTs and normal CTs (i.e., HTPR). RESULTS: In Col/EPI, 73.2% (365/499), 72.6% (390/537), and 55.3% (3,442/6,228) patients showed prolonged CTs for aspirin, clopidogrel, and NSAIDs, respectively. In Col/ADP, prolonged CTs were observed in 37.4% (34/91), 43.2% (35/81), and 29.6% (200/676) of patients receiving aspirin, clopidogrel, and NSAIDs, respectively. Of the patients tested with both cartridges, 88.9% (48/54), 95.3% (41/43), and 89.0% (577/648) of the patients receiving aspirin, clopidogrel, and NSAIDs had prolonged CTs, and 10.0% (79/794) showed normal CTs regardless of drugs. For clopidogrel users (both cartridges), there were more patients with malignancies in the normal CT than prolonged CT group. CONCLUSIONS: PFA-100 is not sufficiently effective for laboratory screening of drug-induced platelet dysfunction. Malignancy may contribute to clopidogrel-related HTPR in PFA-100.

Host modulation therapy in periodontitis / 口腔疾病防治

@#Host modulation therapy (HMT), as a treatment concept for periodontitis, aims to modulate the host immune responses during the pathogenesis of periodontitis. Various drugs have been evaluated as HMT, including subdose doxycycline (SDD), nonsteroidal anti-inflammatory drugs (NSAIDs), bisphosphonates, and cytokine receptors, to modify or modulate inflammatory mediators and associated signaling pathways in the immune-inflammatory response, as well as connective tissue breakdown and bone resorption. SDD, a member of the tetracycline drug family, has been reported to improve periodontal treatment outcomes by inhibiting periodontal breakdown through inhibiting MMPs. NSAIDs may suppress periodontal inflammation by reducing cyclooxygenase-2(COX-2) activity. Combined application of SSD and NSAIDs may achieve a better clinical outcome. Recent studies of HMT treatment have focused on the prevention of excessive inflammation by regulating mediators using endogenous lipid mediators. Local administration of bisphosphonates and histone deacetylase inhibitors can inhibit osteoclast activity and regulate bone tissue remodeling. Currently, SSD is approved by the FDA for periodontal treatment. Other drugs, such as COX-2 selective inhibitor, nonsteroidal anti-inflammatory drugs, bisphosphonates, triclosan and iNOS inhibitors, have good application prospects in the prevention and treatment of periodontal disease, and the mechanism and side effects of these drugs remain to be further investigated.

Analgesic prescribing trends in musculoskeletal disorders

Background: Musculoskeletal disorders like osteoarthritis, rheumatoid arthritis, bursitis, backache, tendinitis, cervical spondylitis etc. are very commonly encountered in orthopaedic practice and are generally treated with various analgesic drugs. There are number of non-steroidal anti-inflammatory drugs (NSAIDs), opiod analgesics and also fixed dose combination (FDC) of analgesics available for the treatment of such disorders with some advantages and disadvantages of these drugs. Since few studies are there on utilization of analgesic drugs in the orthopaedic practice, this study was undertaken to determine the current prescribing trends for these disorders.Methods: It was record based observational study carried out at NKP salve institute of medical sciences, Nagpur. A total of 200 prescriptions of patients reported to orthopaedic outpatient department, with presenting complaints of musculoskeletal disorder and rheumatological conditions like osteoarthritis, rheumatoid arthritis, bursitis, backache, tendinitis, cervical spondylitis etc. were noted for the various analgesic drugs prescribed for these disorders.Results: The common age groups encountered for musculoskeletal disorders were between 41-50 years (26%) and 31-40 years (20%) followed by other age groups. The common conditions for which patient attended orthopaedic outpatient department were low backpain in 42 (21%) and osteoarthritis in 41(20.5%) patients followed by others. Aceclofenac and diclofenac were the most commonly prescribed analgesics in 25 (12.5%) and18 (9%) patients followed by other analgesics. Fixed dose combinations of NSAIDS with other NSAIDS or opoid analgesic were also commonly prescribed. Diclofenac + Paracetamol and Tramadol + Paracetamol were most commonly prescribed combinations in 30 (15%) and 19 (9.5%) patients respectively.Conclusions: As monotherapy aceclofenac and diclofenac were the most commonly prescribed NSAIDS for various musculoskeletal disorders. Also, fixed dose combinations of NSAIDS with other NSAIDS or opoid analgesic were also commonly prescribed. Diclofenac + Paracetamol and Tramadol + Paracetamol were the most commonly prescribed FDCs in our study.
