La causa más frecuente de abandono de tratamiento fue la pandemia.

Introduction: Clubfoot is the most frequent foot deformity in pediatrics. The foot is characterized by having an equine ankle, a varus hindfoot, an adducted forefoot, and a dig in the midfoot. Objectives: to describe the frequency and reasons for abandoning Clubfoot treatment in a pediatric hospital population in the pandemic (2020-2021). Materials and Methods: This was an ambispective, descriptive and observational study. Consecutive case sampling included children from 0 to 6 years of age who were undergoing Clubfoot follow-up in the pediatric trauma service and abandoned treatment. Data were collected from medical records and by telephone interview with parents. The variables were: demographics, characteristics of the deformity, age and education of the mother, family history of Clubfoot and other malformations, recurrence and causes of treatment abandonment. Data were analyzed in SPSS v21. Parental informed consent was requested. Results: During the 2020-2021 period, 25% (101/404) of the patients being monitored at the hospital abandoned treatment. 62 patients were enrolled in the study. 95% presented recurrence and received surgical treatment. The most frequent cause of treatment abandonment, according to the parents, was the difficulties caused by the pandemic. Conclusions: The frequency of treatment abandonment was 25.2%, with a predominance of males. 95% presented relapse and received surgical treatment (Achilles Tenotomy). The most frequent cause of treatment abandonment was the pandemic.

A Follow up Study Among Patients on Opioid Substitution Therapy (OST) in Terms of Relapse Rate, Factors Affecting Relapse Rate and HCV Incidence

Background: Many countries are facing a serious problem with opioid dependence. Opioid Substitution Therapy (OST) is prescribed to dependent opioid users to diminish the use and effects of illicitly acquired opioids. The high relapse rate has been affecting the effectiveness of anti-drug work all over the world.Material & Methods:In this study, 200 patients were taken by simple random sampling technique. 100 patient on Buprenorphine substitution therapy and 100 on Methadone maintenance treatment were studied. Patients diagnosed as cases of Opioid dependence as per ICD-10 were selected within the first 3 months and followed up to 1 year at 3, 6 and 9 months. The study was conducted after approval from the institutional ethics and thesis committee. A 14-item questionnaire based on a four-point scale describing the number of times certain events had occurred in the previous week for relapse was used to find factors affecting relapse.Results:The relapse rate among patients in the BPN group at 3, 6 and 9 months relapse was 29.33%, 20.34% and 19.51% while in the Methadone group, it was 24.05%, 15.87% and 12% respectively. The overall HCV Incidence was 75% among patients on Opioid Substitution Therapy. Conclusion:The findings of the study highlight the role of multiple determinants in opioid dependence and relapse. The obtained results showed that HCV infection was an alarming problem among IV opiate drug users in Punjab.

The Socio-Demographic Factors and Causes of Substance Abuse Relapse: 36 Cases

Background: Relapse is frequent among substance abusers all across the world, and Bangladesh is no exception. Drug-related issues are gradually becoming a hot topic in Bangladesh, from a social, economic, and medical standpoint. The present study aimed to find out sociodemographic factors associated with relapse amongst substance abuser. Material & Methods: This descriptive type of observational study conducted in the Combined Military Hospital and other Government/Private Hospital/Institute especially Central Drug Addict Treatment Center, Dhaka with a total sample size of 36 participants. Detailed information was obtained in each case according to protocol through complete history from patients or their accompanying attendants using a data collection sheet which was read out to them in Bangla. All the information was recorded in the pre fixed protocol. Collected data was classified, edited, coded and entered into the computer for statistical analysis by using SPSS-23. Results: The study found that yaba was the most commonly abused drug among 36 participants, with 27.78% reporting abuse. 27.78% of participants had a psychiatric illness, with the majority being male (97.22%) and Muslim (88.89%). The largest group of participants were aged 31-40 (47.22%) and most were unemployed (83.33%) and married (94.44%). Peer pressure and family problems were the most commonly reported causes of relapse (91.67% and 83.33%, respectively). Other factors such as unemployment, depression, and failure in life also contributed to relapse. Conclusion: Yaba was the most prevalent substance of abuse and the majority of participants were male, had a psychiatric illness, and were unemployed. Peer pressure and family problems were the main causes of relapse.

Correlation between parasitemia and different complications of malaria – The clinical outlook

Background: Malaria is one of the most severe public health problems worldwide. India contributes a substantial burden of malaria. It can cause several complications. Aims and Objectives: This study was conducted to determine the association of parasitemia of current malaria with age of patients, hemoglobin level, liver function test (LFT), platelet count, previous history of malaria, and relapse/recrudescence of malaria up to 1 year. Materials and Methods: An observational study conducted in hospital settings included thin and thick smear preparation with Leishman’s staining to determine the parasitemia as per the WHO guidelines from the blood samples of 280 malaria parasite dual antigen (MPDA) kit positive patients and their details were taken during study period of 2 years. Hemoglobin, LFT, and platelet count were tested and they were correlated with parasitemia. The previous history of malaria was taken and follow-up was done up to 1 year for relapse/recrudescence and their association with parasitemia in current disease was evaluated. Statistical tool R was used for data analysis. Results: Age group 20–40 years was most commonly affected with maximum mean percentage parasitemia. Higher parasitemia was associated with higher grade of anemia, LFT derangement, and thrombocytopenia. Disease severity was maximum for mixed infection followed by falciparum and vivax malaria. About 9.28% of patients with the previous history of malaria developed lower parasitemia in current infection. Relapse rate in vivax malaria –2.325% and recrudescence rate in falciparum malaria–12.5%. Conclusion: Malaria parasitemia should be reported routinely as it carries prognostic importance.

Myosin 1g as a high-risk biomarker in a pediatric patient with lineage switch from acute lymphoblastic leukemia to myeloid phenotype / Miosina 1g como un marcador de alto riesgo en una paciente pediátrica con cambio de linaje de leucemia linfoblástica aguda a fenotipo mieloide

Abstract Background: Myosin 1g (Myo1g) has recently been identified as a potential diagnostic biomarker in childhood acute lymphocytic leukemia (ALL). Case report: We describe the case of a 1-year-old Mexican female patient. Although initially studied for hepatomegaly, an infectious or genetic etiology was excluded. Liver biopsy showed infiltration by neoplastic B-cell precursors (BCPs), and bone marrow (BM) aspirate showed 14.5% of BCPs. In a joint session of the oncology, hematology, and pathology departments, low-risk (LR) BCP-ALL of hepatic origin with aberrant myeloid markers was diagnosed. Although treatment was initiated, the patient presented early with BM relapse. Modest overexpression of Myo1g was observed from the onset. However, at the end of the steroid window, expression increased significantly and remained elevated during this first relapse to BM. The parents refused hematopoietic stem cell transplantation, but she continued chemotherapy. After a second BM relapse at 5 years of age, the phenotype switched to myeloid. Her parents then opted for palliative care, and the patient died two months later at home. Conclusions: This case shows the potential use of Myo1g in clinical practice as a high-risk indicator. Myo1g monitoring may reveal a high risk and relapse trend, even when typical parameter values are not altered: Myo1g could be used to classify patients from low to high risk from diagnosis, allowing patients to promptly receive the best treatment and potentially modifying prognosis and survival.

Resumen Introducción: Recientemente se ha identificado a miosina 1g (Myo1g) como un potencial biomarcador de diagnóstico en la leucemia linfoblástica aguda (LLA) infantil. Caso clínico: Se describe el caso de una paciente mexicana de 1 año de edad. Aunque inicialmente se estudió por hepatomegalia, se descartó una etiología infecciosa o genética. La biopsia hepática mostró infiltración por precursores de células B neoplásicas (PCB) y un aspirado de médula ósea (MO) mostró 14.5% de PCB. En una sesión conjunta de los departamentos de oncología, hematología y patología, se diagnosticó PCB-LLA de bajo riesgo de origen hepático con marcadores mieloides aberrantes. Aunque se inició tratamiento, la paciente presentó tempranamente recaída de MO. Se observó una modesta sobreexpresión de Myo1g. Sin embargo, al final de la ventana de esteroides, la expresión aumentó considerablemente y permaneció elevada durante esta primera recaída a MO. El trasplante de células madre hematopoyéticas fue rechazado por los padres, pero se continuó con la quimioterapia. Tras una segunda recaída de MO a los 5 años, el fenotipo cambió a mieloide. Sus padres optaron entonces por cuidados paliativos y la paciente falleció dos meses después en su domicilio. Conclusiones: Este caso muestra el potencial uso de Myo1g como indicador de alto riesgo en la práctica clínica. El seguimiento de Myo1g puede revelar una tendencia de alto riesgo y recaídas, incluso cuando los valores de los parámetros rutinarios son aparentemente normales; Myo1g podría utilizarse para clasificar a los pacientes de bajo a alto riesgo desde el diagnóstico, lo que permitiría que los pacientes reciban el mejor tratamiento de manera oportuna, modificando potencialmente el pronóstico y la supervivencia.

Infiltración del nervio óptico como forma inicial de recaída de la leucemia linfoblástica aguda / Optic nerve infiltration as an initial form of relapse of acute lymphoblastic leukemia

Introducción: La infiltración del nervio óptico como forma inicial de recaída de la leucemia linfoblástica aguda es rara, aunque altamente indicativa de que el sistema nervioso central está involucrado. Objetivo: Actualizar el conocimiento sobre infiltración del nervio óptico como forma inicial de recaída de la leucemia linfoblástica aguda. Métodos: Se realizó una revisión de las publicaciones más relevantes relacionadas con el tema durante los últimos años. La búsqueda y la localización de la información se apoyaron en la elección de palabras clave/descriptores que configuraron el perfil de búsqueda. Se utilizó el MeSH Database de PubMed. Se realizó una extensa revisión en Google Académico y otros megabuscadores de revisión sistemática mediante TripDatabase y Cochrane. Conclusiones: La infiltración directa de células tumorales y las alteraciones hematológicas propias de la enfermedad constituyen los mecanismos fundamentales de la fisiopatogenia. El edema del disco óptico es su signo oftalmoscópico más distintivo. La imagen por resonancia magnética de cráneo, el análisis citológico del fluido cerebroespinal y la biopsia de médula ósea negativas no deben excluir el diagnóstico. La terapia combinada que incluye la radiación localizada constituye una buena opción de tratamiento. Un número considerable de ojos recuperan su agudeza visual y muestran resolución del cuadro infiltrativo(AU)

Introduction: Optic nerve infiltration as an initial form of relapse of acute lymphoblastic leukemia is rare, although it is highly indicative of central nervous system involvement. Objective: To update the knowledge about optic nerve infiltration as an initial form of relapse of acute lymphoblastic leukemia. Methods: A review of the most relevant publications related to the subject during the last years was carried out. The search and localization of information was supported by the choice of keywords/descriptors that configured the search profile. The MeSH Database of PubMed was used. An extensive review was performed in Google Scholar and other systematic review mega search engines using TripDatabase and Cochrane. Conclusions: Direct tumor cell infiltration and disease-specific hematologic alterations are the fundamental mechanisms of pathophysiology. Optic disc edema is the most distinctive ophthalmoscopic sign. Negative cranial magnetic resonance imaging, cytologic analysis of cerebrospinal fluid and bone marrow biopsy should not exclude the diagnosis. Combination therapy including localized radiation is a good treatment option. A considerable number of eyes recover visual acuity and show resolution of the infiltrative picture(AU)

Blood parasite load by qPCR as therapeutic monitoring in visceral leishmaniasis patients in Brazil: a case series study

ABSTRACT Background: This study aimed to describe the kinetics of Leishmania parasite load determined using kinetoplast DNA (kDNA)-based quantitative polymerase chain reaction (qPCR) in visceral leishmaniasis (VL) patients. Methods: Parasite load in blood was assessed by qPCR at five time points, up to 12 months post-diagnosis. Sixteen patients were followed up. Results: A significant reduction in the parasite load was observed after treatment (P < 0.0001). One patient had an increased parasite load 3 months post-treatment and relapsed clinically at month six. Conclusions: We have described the use of kDNA-based qPCR in the post-treatment follow-up of VL cases.

Efficacy and safety of secondary allogeneic hematopoietic stem cell transplantation in 70 patients with recurrent hematologic malignancies after transplantation / 中华血液学杂志

Objectives: To investigate the role of donor change in the second hematopoietic stem cell transplantation (HSCT2) for hematological relapse of malignant hematology after the first transplantation (HSCT1) . Methods: We retrospectively analyzed patients with relapsed hematological malignancies who received HSCT2 at our single center between Mar 1998 and Dec 2020. A total of 70 patients were enrolled[49 males and 21 females; median age, 31.5 (3-61) yr]. Results: Forty-nine male and 21 female patients were enrolled in the trial. At the time of HSCT2, the median age was 31.5 (3-61) years old. Thirty-one patients were diagnosed with acute myeloid leukemia, 23 patients with ALL, and 16 patients with MDS or other malignant hematology disease. Thirty patients had HSCT2 with donor change, and 40 patients underwent HSCT2 without donor change. The median relapse time after HSCT1 was 245.5 (26-2 905) days. After HSCT2, 70 patients had neutrophil engraftment, and 62 (88.6%) had platelet engraftment. The cumulative incidence of platelet engraftment was (93.1±4.7) % in patients with donor change and (86.0±5.7) % in patients without donor change (P=0.636). The cumulative incidence of CMV infection in patients with and without donor change was (64.0±10.3) % and (37.0±7.8) % (P=0.053), respectively. The cumulative incidence of grade Ⅱ-Ⅳ acute graft versus host disease was (19.4±7.9) % vs (31.3±7.5) %, respectively (P=0.227). The cumulative incidence of TRM 100-day post HSCT2 was (9.2±5.1) % vs (6.7±4.6) % (P=0.648), and the cumulative incidence of chronic graft versus host disease at 1-yr post-HSCT2 was (36.7±11.4) % versus (65.6±9.1) % (P=0.031). With a median follow-up of 767 (271-4 936) days, 38 patients had complete remission (CR), and three patients had persistent disease. The CR rate was 92.7%. The cumulative incidences of overall survival (OS) and disease-free survival (DFS) 2 yr after HSCT2 were 25.8% and 23.7%, respectively. The cumulative incidence of relapse, OS, and DFS was (52.6±11.6) % vs (62.4±11.3) % (P=0.423), (28.3±8.6) % vs (23.8±7.5) % (P=0.643), and (28.3±8.6) % vs (22.3±7.7) % (P=0.787), respectively, in patients with changed donor compared with patients with the original donor. Relapses within 6 months post-HSCT1 and with persistent disease before HSCT2 were risk factors for OS, DFS, and CIR. Disease status before HSCT2 and early relapse (within 6 months post-HSCT1) was an independent risk factor for OS, DFS, and CIR post-HSCT2. Conclusion: Our findings indicate that changing donors did not affect the clinical outcome of HSCT2.

Comparative analysis of clinical characteristics and short-term prognosis between type A and type B male patients with alcohol dependence / 中华行为医学与脑科学杂志

Objective:To explore the differences in clinical characteristics and treatment outcomes between patients with type A and type B alcohol dependence, and to find the independent risk factors of relapse.Methods:Alcohol-dependent male patients attending the Addiction Medicine Center of Beijing Huilongguan Hospital from January 2018 to December 2020 were selected for the study and divided into type A alcohol-dependent group ( n=77) and type B alcohol-dependent group ( n=87). All patients were given acute detoxification treatment and were followed up after treatment on relapse to drinking. Differences in demographic and clinical data were compared between the two groups, and differences in treatment outcomes between the two groups at different time points over 3 months were compared. Patients were divided into relapse group and non-relapse group according to whether they drank again after 3 months. Logistic regression model was established to screen the risk factors of relapse of alcohol-dependent patients by SPSS 25.0 software. Results:There was no significant difference between the two types of patients in years of education, marital status, smoking status and working status(all P>0.05), but the proportion of co-residents( χ2=5.69, P=0.017) and the proportion of positive family history of alcoholism were significant difference between the two type of patients( χ2=13.32, P<0.001). There were statistically significant differences between the two types of patients in the onset time( t=-7.28, P<0.001), the first drinking age( t=-2.36, P=0.020), the proportion of drinking in the morning( χ2=7.83, P=0.005), psychotic symptoms( χ2=4.31, P=0.038), convulsions after withdrawal( χ2=5.30, P=0.021), and alcohol use disorder identification test(AUDIT) score( t=4.30, P<0.001). At the 4th and 8th weekend of the follow-up, there were statistically significant differences in drinking frequency(0(0, 3), 0(0, 0), Z=-4.13, P<0.001; 3(0, 3), 0(0, 3), Z=-4.42, P<0.001) and relapse rate (40(45.98%), 9(11.69%), χ2=22.92, P<0.001; 61(70.11%), 24(31.17%), χ2=24.82, P<0.001) between the two types of alcohol dependence patients after drinking again. After 12-week follow-up, there were statistically significant differences between the two types of alcohol-dependent patients in the interval of first drinking(20(7, 30)d, 88(38, 90)d, Z=-7.83, P<0.001), the cumulative duration of abstinence(4(0, 8)weeks, 12(4, 12)weeks, Z=-5.13, P<0.001), the cumulative rate of abstinence(71(81.60%), 25(32.47%), χ2=40.62, P<0.001), the frequency of drinking after abstinence(3(3, 3), 0(0, 3), Z=-5.54, P<0.001), and the reduction of daily average alcohol consumption( t=3.36, P<0.001). Logistic regression model showed that type B alcohol dependence ( OR=3.121, P=0.03, 95% CI: 1.12-8.72) and AUDIT score ( OR=1.498, P<0.01, 95% CI: 1.29-1.74) were the risk factors for relapse of alcohol-dependent patients. Conclusions:Patients with type A and type B alcohol dependence have obvious differences in clinical characteristics and treatment outcomes, and type B alcohol dependence is independent risk factor for relapse to drinking in alcohol-dependent patients, which validate the rationality and necessity of alcohol dependence subtypes.

Related factors of relapse based on positive and negative syndrome scale among schizophrenics in Shanghai communities / 上海预防医学

ObjectiveTo explore the relapse status based on the positive and negative syndrome scale （PANSS Scale） and related factors of schizophrenics in Shanghai communities， and to analyze the association between socio demographic characteristics， lifestyles， clinical characteristics and relapse. MethodsA dynamic cohort prospective study design was used in this study. From March 2018 to February 2019， a total of 189 schizophrenics in Xuhui， Hongkou， Changning， Jiading， Songjiang and Baoshan districts were enrolled successively. Baseline questionnaires were conducted through face-to-face interviews at baseline， which contained social demographic information， lifestyle information and clinical information. A follow-up was conducted every 2 weeks for a measurement of PANSS Scale for a total of 6 months. Relapse was assessed by a PANSS score increase of ≥25% from baseline （or an increase of 10 points or more if the baseline score was ≤40 points）. Univariate and multivariate Cox regression models were used to analyze the associations between relapse status （assessed by PANSS Scale） and socio demographic characteristics， lifestyles， and clinical characteristics， respectively. ResultsA total of 165 community schizophrenics completed baseline and follow-up surveys， with a loss to follow-up rate of about 12.7%. After exclusion of sociodemographic and clinical information deficits， 132 patients were included in the analysis totally， with an average age of 48.18±12.67 years， among whom 41.67% were male. Totally 33 patients relapsed during the 6-month follow-up period， with a relapse rate of 25.0%. After adjusting for gender， family history， age， employment， education， marital status， smoking， drinking， exercise frequency， medication compliance， insight， social function， violence history， stress recent events， adverse drug reactions and baseline scores of PANSS Scale， risk factors of relapse included the following four factors： age below 40 years （HR=4.47， 95%CI： 1.15-17.40）， primary school or below （HR=7.11， 95%CI： 1.54-32.83）， unemployed （HR=8.34， 95%CI： 1.78-38.98）， and adverse drug reactions （HR=5.02， 95%CI： 1.75-14.37）. ConclusionWe should pay attention to the risk factors such as age， education， employment and adverse drug reactions， in order to identify high-risk patients and to conduct timely interventions during the relapse management of schizophrenics in Shanghai community.

Treatment progress of relapsed/refractory peripheral T-cell lymphoma / 白血病·淋巴瘤

Peripheral T-cell lymphoma (PTCL) is a highly heterogeneous disease with numerous subtypes, and the overall prognosis is poor, especially in relapsed/refractory patients, and the patients are generally older with limited treatment options that can be tolerated. At the 64th American Society of Hematology (ASH) Annual Meeting in 2022, studies on relapsed/refractory PTCL include the combination of epigenetic agents or combination of immune checkpoint inhibitors, CD30 antibody-drug conjugate (ADC) brentuximab vedotin combined with chemotherapy, targeted drugs PI3K inhibitors and JAK1 inhibitors, etc., providing more choices and opportunities for relapsed/refractory patients.

Analysis of the Prognostic Value and Risk Factors of Early Relapse for Newly Diagnosed Multiple Myeloma Patients in the Era of Novel Agents / 中国实验血液学杂志

OBJECTIVE@#To investigate the influece of early relapse in the era of novel drugs on the prognosis of the patients with newly diagnosed multiple myeloma（NDMM） and risk factors, and to provide the basis for the early identification of the high-risk patients and guiding the treatment.@*METHODS@#The clinical data of the patients with NDMM admitted to our hospital from November 2011 to May 2022 were retrospectively analyzed. According to whether the progression free survival（PFS） was more than 12 months, they were divided into early relapse group（≤12 months） and late relapse group（＞12 months）. The high-risk factors of the patients in two groups were analyzed, including age, anemia, renal insufficiency, hypercalcemia, increasing of lactate dehydrogenase（LDH） level, Extramedullary disease (EMD), International Staging System（ISS） stage, Revised International Staging System （R-ISS） stage, cytogenetic abnormalities(CA) detected by fluorescence in situ hybridization（FISH）, and treatment efficacy. The meaningful clinical indicators were screened, and multivariate analysis was used to explore the high-risk factors of early relapse.@*RESULTS@#170 patients with NDMM were collected, including 25 cases in early relapse group and 145 cases in late relapse group. The median OS time of the patients in early death group was 20 months, and 140 months in late relapse group by the end of follow-up, there was significant difference in OS of the patients between two groups（P<0.001）. Fifteen patients（56.0％）in early relapse group obtained ≥VGPR, and 113（77.9%） patients in late relapse group, the difference was statistically significant（P=0.011）. Survival outcomes remained poor among early relapse patients irrespective of depth of response to initial therapy. Multivariate analysis showed that the EMD and high-risk CA predicted early relapse.@*CONCLUSION@#The prognosis of patients with early relapse in NDMM is poor. EMD and high-risk CA is an independent prognostic factor of early relapse.

Efficacy and safety of low-dose rituximab in treatment of pediatric nephrotic syndrome: a prospective randomized controlled trial / 中国当代儿科杂志

OBJECTIVES@#To study the efficacy and safety of repeated application of rituximab (RTX) at a low dose (200 mg/m2) versus the recommended dose (375 mg/m2) for remission maintenance in frequently relapsing nephrotic syndrome (FRNS) or steroid-dependent nephrotic syndrome (SDNS).@*METHODS@#A randomized controlled trial was conducted for 29 children with FRNS/SDNS who received systemic treatment in the Department of Nephrology, Anhui Provincial Children's Hospital, from September 2020 to December 2021. These children were divided into a recommended dose group (n=14) and a low dose group (n=15) using a random number table. The two groups were compared in terms of general characteristics, changes in CD19 expression after RTX treatment, number of relapses, glucocorticoid dose, adverse reactions of RTX, and hospital costs.@*RESULTS@#After RTX treatment, both the low dose group and the recommended dose group achieved B-lymphocyte depletion and had significant reductions in the number of relapses and glucocorticoid dose (P<0.05). The low dose group had a comparable clinical effect to the recommended dose group after RTX treatment (P>0.05), and the low dose group had a significant reduction in hospital costs for the second, third, and fourth times of hospitalization (P<0.05). There were no serious adverse reactions in either group during RTX treatment and late follow-up, and there was no significant difference in adverse reactions between the two groups (P>0.05).@*CONCLUSIONS@#Repeated RTX treatment at a low dose has comparable clinical efficacy and safety to that at the recommended dose and can significantly reduce the number of FRNS/SDNS relapses and the amount of glucocorticoids used, with little adverse effect throughout the treatment cycle. Therefore, it holds promise for clinical application.

Surgical management of chronic osteomyelitis: Organisms, recurrence and treatment outcome / 中华创伤杂志(英文版)

PURPOSE@#The study aimed to identify the risk factors of recurrence in chronic osteomyelitis (COM) and to document the microbiological patterns pre- and intra-operatively and at recurrence, if any.@*METHODS@#We performed retrospective review on COM patients treated with surgical debridement and a 6-week course of antibiotics. The patients with symptoms of osteomyelitis for at least 6 weeks, present or past episodes of discharging sinus, documentation of bone sequestration in operative notes or preoperative images were included in the study. Patients with symptoms of osteomyelitis < 6 weeks, lack of history of discharging sinus or lack of evidence of sequestration in preoperative images or intraoperative notes were excluded. Logistic regression models were used to assess the impact of risk factors of recurrence. Cohen-Kappa scores were derived to see the concordance between pre-operative and intra-operative isolates and at recurrence.@*RESULTS@#Totally, 147 COM patients (115 males and 32 females, mean age (33 ± 19) years) were included in this study. Recurrence was noted in 28 patients (19.0%). Polymicrobial growth and extended spectrum beta-lactamase producing Enterobacteriaceae increased the chance of recurrence. Cierny-Mader stage-1, hematogenous aetiology and negative intraoperative culture reduced the chance of recurrence. Concordance between pre-operative and intra-operative cultures was 59.85% (Kappa score 0.526, p < 0.001) and between index surgery and at recurrence was 23.81% (Kappa score 0.155, p < 0.001). Lack of knowledge of causative organism preoperatively did not affect outcome. At mean follow-up (42 ± 15) months, all patients were apparently infection free for at least 1 year.@*CONCLUSION@#Polymicrobial growth and multi-drug resistant organisms increase the risk of recurrence in COM. Patients' age, gender, diabetes mellitus, previous failed treatment, duration of symptoms, haemoglobin, white cell count, C-reactive protein and erythrocyte sedimentation rate at presentation did not have any impact on the recurrence of infection. Pre-operative isolation of organism is of questionable value. Recurrences of infections do occur and are more of re-infections than relapses. Diligent isolation of organism must be attempted even in re-debridements. Even patients with recurrences do well with appropriate debridement and antibiotic therapy.

Comparison between round multi-strand wire and rectangular wire bonded retainers: a randomized clinical trial

ABSTRACT Objective: The primary objective was to compare round multi-strand wire and Ortho-Flex-Tech™ rectangular wire retainers in terms of gingival health. The secondary objectives were to assess plaque/calculus accumulation, and to determine the effectiveness of these retainers in maintaining tooth alignment and their failure rate. Material and Methods: This single-center study was a two-arm parallel randomized clinical trial and was conducted at the Orthodontic clinics in Dental Teaching Center/Jordan University of Science and Technology. Sixty patients, with bonded retention for the mandibular anterior segment after fixed orthodontic treatment, were randomly selected. The sample comprised Caucasian patients with mild to moderate pretreatment crowding in the mandibular anterior region, Class I relationship, treated without extraction of mandibular anterior tooth. In addition, only patients presenting normal overjet and overbite after treatment were included. Intervention: One group received round multi-strand wire retainer (30 patients, average age: 19.7 ± 3.8 years), while the other group received Ortho-Flex-Tech™ retainer (30 patients; average age: 19.3 ± 3.2 years). In both groups, the retainers were bonded to all mandibular anterior teeth from canine to canine. All patients were recalled one year after bracket debonding. Randomization sequence was created using Excel 2010, with a 1:1 allocation, using random block size 4. The allocation sequence was concealed in sequentially numbered, opaque and sealed envelopes. Only participants were blinded to the type of bonded retainer used. The primary outcome was to compare the gingival condition between the two groups. The secondary outcomes were to assess plaque/calculus indices, irregularity index of the mandibular anterior teeth and retainers' failure rate. Comparisons were conducted using Mann-Whitney U test or chi-square test. Statistical significance was predetermined at the p≤ 0.05 level for all tests. Results: Complete data were collected for 46 patients (round multi-strand wire retainer group, n=24 patients; rectangular Ortho-Flex-Tech™ retainer group, n=22 patients). No significant differences were found in the gingival health parameters between the two groups (p>0.05). Ortho-Flex-Tech™ retainers maintained the alignment of mandibular anterior teeth more than multi-strand retainer (p<0.05). No significant difference was found in the failure rate between the two groups (p>0.05). Conclusions: Gingival health parameters and failure rate were not different in both groups. However, Ortho-Flex-Tech™ retainers were more efficient to retain the mandibular incisors than the multi-strand retainers; nevertheless, the difference was not clinically significant.

RESUMO Objetivo: O objetivo principal desse estudo foi comparar a saúde gengival após o uso de dois tipos de contenção: uma feita com fio redondo multifilamentado e outra feita com fio retangular Ortho-Flex-Tech™. Os objetivos secundários foram avaliar o acúmulo de placa/cálculo, determinar a eficácia dessas contenções em manter o alinhamento dos dentes, bem como sua taxa de falha. Material e Métodos: Esse foi um estudo unicêntrico do tipo ensaio clínico randomizado paralelo de dois braços, conduzido nas clínicas ortodônticas do Centro de Ensino Odontológico da Jordan University of Science and Technology (Jordânia). Foram selecionados aleatoriamente sessenta pacientes com contenção colada no segmento anterior inferior após tratamento ortodôntico fixo. A amostra foi composta por pacientes caucasianos com apinhamento pré-tratamento leve a moderado na região anterior inferior, relação de Classe I, tratados sem extração de dentes anteriores inferiores. Além disso, foram incluídos apenas os pacientes que apresentavam sobressaliência e sobremordida normais após o tratamento. Intervenção: Um grupo recebeu contenção com fio redondo multifilamentado (30 pacientes, idade média: 19,7 ± 3,8 anos), enquanto o outro grupo recebeu contenção com fio retangular Ortho-Flex-Tech™ (30 pacientes; idade média: 19,3 ± 3,2 anos). Em ambos os grupos, as contenções foram coladas em todos os dentes anteriores inferiores de canino a canino. Todos os pacientes retornaram um ano após a descolagem dos braquetes. A sequência de randomização foi criada no Excel 2010, com uma alocação de 1:1, usando tamanho de bloco aleatório 4. A sequência de alocação foi ocultada em envelopes numerados sequencialmente, opacos e lacrados. Apenas os participantes desconheciam o tipo de contenção usada. O resultado primário foi a comparação dos dois grupos quanto à condição gengival. Os resultados secundários foram a avaliação dos índices de placa/cálculo, índice de irregularidade dos dentes anteriores inferiores e taxa de falha das contenções. As comparações foram realizadas usando o teste U de Mann-Whitney ou o teste qui-quadrado. A significância estatística foi predeterminada ao nível de p≤ 0,05 para todos os testes. Resultados: Dados completos foram coletados para 46 pacientes (grupo de contenção com fio multifilamentado redondo, n=24 pacientes; grupo de contenção com fio retangular Ortho-Flex-Tech™, n=22 pacientes). Nenhuma diferença significativa foi encontrada entre os dois grupos para os parâmetros de saúde gengival (p>0,05). As contenções Ortho-Flex-Tech™ mantiveram mais o alinhamento dos dentes anteriores inferiores do que as contenções com fio multifilamentado (p<0,05). Nenhuma diferença significativa foi encontrada entre os dois grupos quanto à taxa de falha (p>0,05). Conclusões: Os parâmetros de saúde gengival e a taxa de falhas não foram diferentes entre os dois grupos. No entanto, as contenções Ortho-Flex-Tech™ foram mais eficientes em conter os incisivos inferiores do que as contenções com fio multifilamentado; no entanto, essa diferença não foi clinicamente significativa.

Recaída en el consumo de alcohol después del trasplante de hígado por hepatopatía alcohólica / Alcohol relapse after liver transplantation for alcoholic liver disease

Introducción. La enfermedad hepática inducida por uso de alcohol se ha considerado una enferme-dad autoinfligida que limitaba el acceso al trasplante. Actualmente es una de las principales indicacio-nes de trasplante hepático en Colombia y el mundo, con excelente sobrevida. Metodología. Estudio descriptivo observacional donde se realizó una caracterización de los pacientes con trasplante hepá-tico por hepatopatía alcohólica en una institución de cuarto nivel, que incluyó un estudio cualitativo de la recaída en el consumo de alcohol postrasplante. Resultados. De 87 pacientes de una cohorte inicial de 96 pacientes trasplantados entre 2003 y 2021, se describieron características sociodemo-gráficas, comorbilidades previas y adquiridas posterior al trasplante, supervivencia del paciente y del injerto, y factores de riesgo asociados al consumo de alcohol. Adicionalmente, a 65 pacientes se les pudo realizar una entrevista estructurada para evaluar la recaída en el consumo de alcohol, 41,53 % volvieron a consumir alcohol; 23,07 % en patrón de riesgo de recaída y 18,46 % en patrón de slip (desliz). El antecedente de hepatitis alcohólica tuvo un RR de 3,273 (1,464­7,314) y p=0,007 para recaída en el consumo de alcohol, y la comorbilidad psiquiátrica un RR de 2,395 (1,002­5,722) y p=0,047. Finalmente, haber presentado al menos una recaída postrasplante tuvo un RR de 5,556 (1,499­20,588) con p=0,005 para rechazo del injerto. Conclusiones. La recaída en el consumo de alcohol fue frecuente, la hepatitis alcohólica previa y la comorbilidad psiquiátrica son factores de riesgo asociados. La recaída se asoció a rechazo del injerto sin afectar la sobrevida del paciente.

Introduction. Alcohol-induced liver disease has been considered a self-inflicted disease that limited access to transplantation. It is currently one of the main indications for liver transplantation in Colom-bia and the world, with excellent survival. Methodology. Observational descriptive study where a characterization of liver transplant patients due to alcoholic liver disease was carried out in a fourth level institution, which included a qualitative study of relapse in post-transplant alcohol consumption. Results. Of 87 patients from an initial cohort of 96 transplant patients between 2003 and 2021, sociodemographic characteristics, previous and acquired post-transplant comorbidities, patient and graft survival, and risk factors associated with alcohol consumption were described. Additionally, 65 patients were able to undergo a structured interview to assess relapse in alcohol consumption, 41.53% returned to alcohol consumption; 23.07% in risk relapse pattern, and 18.46% in slip pattern. The history of alcoholic hepatitis had a RR of 3.273 (1.464-7.314) and a p=0.007 for relapse in alcohol consumption, and psychiatric comorbidity a RR of 2.395 (1.002-5.722) and a p=0.047. Finally, having presented at least one post-transplant relapse had a RR of 5.556 (1.499-20.588) with ap=0.005 for graft rejection. Conclusions. Relapse in alcohol consumption was fre-quent, previous alcoholic hepatitis and psychiatric comorbidity were associated risk factors. Relapse was associated with graft rejection without affecting patient survival.

Inteligencia emocional como mediador del craving y el riesgo de recaída en adultos en tratamiento por consumo de alcohol

Objetivos: Analizar el efecto de craving sobre el riesgo de recaída en adultos en tratamiento por alcohol, considerando la Inteligencia Emocional Percibida (IEP) como mediador. Materiales y métodos: Estudio descriptivo, transversal, predictivo, de comprobación de modelo con análisis de mediación. La muestra fue de 274 adultos internos en Centros de Rehabilitación contra las Adicciones (CRCA). Los instrumentos utilizados fueron una Cédula de Datos Sociodemográficos, Cuestionario de Craving por Alcohol, Inventario de Cociente Emocional y Cuestionario de Variables Predictoras de Abandono y Adhesión al Tratamiento. Resultados: Existe una relación inversa entre la IEP, el riesgo de recaída (r = -,381, p <,001) y el craving (r = -,354, p <,001). El craving y el riesgo de recaída se relacionaron positivamente (r = ,218, p <,001). Se reporta un efecto total significativo del craving sobre el riesgo de recaída cuando es mediado por la IE, el cual explica el 11 % de la varianza (B = ,1389; t = 5,688; p <,001). Conclusiones: Los resultados de este estudio indican que IEP se asocia inversamente con el craving y el riesgo de recaída, además de que la IEP desempeña un papel significativo como mediador en esta relación. Esto sugiere que las personas con altos niveles de IEP disponen de más recursos para gestionar sus emociones, lo que podría ayudar a reducir las conductas de craving y, consecuentemente, sufrir un menor riesgo de recaída en el consumo de alcohol.

Objectives: To analyze the effect of craving on the risk of relapse in adults undergoing alcohol treatment, considering the Perceived Emotional Intelligence (PEI) as a mediator. Materials and methods: Descriptive, cross-sectional, predictive study, model checking with mediation analysis. The sample consisted of 274 adults interned in Rehabilitation Centers against Addictions (CRCA). The instruments used were a Sociodemographic Data Card, Alcohol Craving Questionnaire, Emotional Quotient Inventory and Questionnaire of Variables Predictors of Abandonment and Adherence to Treatment. Results: There is an inverse relationship between PEI, the risk of relapse (r = -, 381, p <,001) and craving (r = -, 354, p <,001). Craving and risk of relapse were positively related (r = ,218, p <,001). A significant total effect of craving on the risk of relapse is reported when mediated by EI, which explains 11% of the variance (B = ,1389; t = 5,688; p <,001). Conclusions: The results of this study indicate that PEI is inversely associated with craving and risk of relapse, and that PEI plays a significant role as a mediator in this relationship. This suggests the notion that people with high PEI levels have more resources to manage their emotions, which could help reduce craving behaviors and consequently, suffer a lower risk of relapse into alcohol consumption.

Isolated Extramedullary Relapse in the Gastrointestinal Mucosa of a Patient with T cell Lymphoblastic Lymphoma

An unusual case of extramedullary relapse in a known case of T cell lymphoblastic lymphoma is presented here. The patient is a 24-year-old girl diagnosed with T cell lymphoblastic lymphoma in June 2020. The patient th showed extramedullary relapse in the gastrointestinal mucosa without bone marrow recurrence whilst on the 6 month of BFM (Berlin Frankfurt Munster) -90 maintenance. Isolated gastrointestinal infiltrate is unusual at presentation or relapse of T cell lymphoblastic lymphoma. While on BFM-90 maintenance, she presented with multiple vomiting and abdominal pain episodes. Upper gastrointestinal scopy revealed multiple gastric ulcers, with morphology and immune-phenotyping identical to her initial T cell lymphoblastic lymphoma. We could not find evidence of leukaemic activity in the blood, cerebrospinal fluid or bone marrow. Several types of leukemic infiltrates have been recognised at post-mortem examination; the fact that makes our case is unique is T cell lymphoblastic lymphoma presenting as an isolated malignant ulcer, which to the best of our knowledge, has not been reported. We conclude that relapsed T cell lymphoblastic lymphoma may present with gastrointestinal infiltration. Further investigations are warranted to establish the same

Real-world observational study of escitalopram for newly diagnosed versus relapsed patients with major depressive disorder in India

Background: Depression is common yet under-reported disorder in the real-world setting. Although antidepressants have demonstrated superiority over placebo in clinical trials, many patients elicit a suboptimal response or relapse. Moreover, real-world data in the Indian population are limited. Aim and Objective: This study aims to assess and compare the efficacy and safety of escitalopram in patients with newly diagnosed depression (NDD) versus relapse in India. Materials and Methods: This is an ongoing real-world observational study of escitalopram in patients with NDD or relapse in India. Primary endpoint was change in mean Hamilton Depression Rating Scale (HAM-D 17) scores from baseline to week 8. Secondary endpoints included assessment of response/remission rates, Clinical Global Impression (CGI) scores, quality of life, suicidal tendency, and safety. Results: Data for the first 50 patients demonstrated a significant reduction in HAM-D 17 scores at week 8 (P < 0.001); patients with NDD (n = 38) elicited significantly higher improvement compared with relapsed patients (n = 12) (P < 0.001). Although patients with NDD had significantly poorer CGI (P < 0.001) and quality of life (anxiety/depression subscale) (P < 0.05) scores at baseline, an improvement was observed in both scales with no significant difference between the groups at week 8. Suicidal tendency reduced from 83.3% to 0%. No new safety concerns were observed in the study. Conclusion: Escitalopram demonstrated efficacy and was well tolerated in both, NDD and relapsed patients in the real-world setting in India, with better results achieved by NDD patients. However, more studies are required to confirm the difference across the groups.

Need for Mindfulness-based Relapse Prevention Strategies for Postpartum Smoking Relapse Prevention

The health concerns for women are varied from that of men and are of higher concern. To increase this concern, women have recorded higher smoking relapse rates than men were an alarming 60% to 90% of the women who have attempted to quit relapse within their first year. Women who quit during pregnancy are seen to have higher rates of relapse than others. Such postpartum relapse has detrimental effects on the mother as well as the newborn. Mindfulness?based interventions have seen benefits in the areas of substance abuse and relapse prevention. Although research in the area of mindfulness and its benefits on smoking cessation has been limited, literature shows positive outcomes. This brief article examines the need for mindfulness-based relapse prevention strategies for women who are undergoing postpartum smoking relapses so that they could benefit from the same.
