OBJECTIVES
The present study is a randomized trial for comparing the effectiveness of tranexamic acid as an antifibrinolytic agent in preventing alveolar osteitis in the post-extraction period in patients receiving orthodontic therapy that requires extraction.
METHODOLOGY
This research was carried out in the Department of Oral and Maxillofacial Surgery, Saveetha Dental College and Hospitals, Chennai, India. A total of 40 patients were considered subjects for the research. Patients undergoing orthodontic treatment referred to the Department of Oral and Maxillofacial Surgery for the therapeutic extractions of the first premolars were considered for this study. Randomization was done to split the population into study and control. After the atraumatic extraction of the first premolars under local anesthesia using 2% lignocaine with 1:80000 adrenaline, a tranexamic acid solution of 500 mg soaked gauze over the extraction sockets was used as the intervention in the study group, and plain gauze was used on the control group. Patients were asked to hold the gauze in place for one hour. Participants were reviewed after three days for the incidence of alveolar osteitis and pain severity and healing of the extraction sockets. Results: The prevalence of Alveolitis sicca dolorosa was found to be 5% in the research group and 15% in the control group. Patients in the control group showed more pain than the patients in the research group. The period taken for healing ranged from 7 days to 10 days in the control group and 10 days to 12 days in the study group. Conclusion: This study gives an edge that tranexamic acid can be used as a local hemostatic agent in preventing fibrinolysis of clots and preventing alveolar osteitis.

Hip and pelvis region MRI reference image atlas for scoring inflammation in peripheral joints and entheses according to the OMERACT-MRI WIPE scoring system in patients with spondyloarthritis.
OBJECTIVE
To develop a reference image atlas for scoring the hip/pelvis region according to the OMERACT whole-body MRI scoring system for inflammation in peripheral joints and entheses (MRI-WIPE).
METHODS
We collected image examples of each pathology, location and grade, discussed them at web-based, interactive meetings and, finally, selected reference images by consensus.
RESULTS
Reference images for each grade and location of osteitis, synovitis and soft tissue inflammation are provided, as are definitions, reader rules and recommended MRI-sequences.
CONCLUSION
A reference image atlas was created to guide scoring whole-body MRIs for arthritis and enthesitis in the hip/pelvis region in spondyloarthritis/psoriatic arthritis clinical trials and cohorts.

INTRODUCTION
Primary hyperparathyroidism (PHPT) is an intrinsic abnormality of the parathyroid glands in which there is an inappropriate secretion of parathormone (PTH), resulting in skeletal resorption and bone loss. The characteristic bony changes of fibrotic cystic lesions are called Brown's tumors. Clinical dilemmas exist due to the varied clinical presentation of hypercalcemia with multiple lytic lesions mimicking metastatic bone disease. The 99 mTc sestamibi scanning is the imaging modality of choice used for the preoperative localization of parathyroid adenomas. Surgery provides a definitive treatment, and the bony lesions resolve completely over a period of time.
CASE REPORT
We present four cases of PHPT where they presented with multiple lytic lesions and were evaluated for metastatic deposits. The diagnosis was confirmed with a biopsy. They were successfully treated by excision of the parathyroid gland. A high index of suspicion will avoid misdiagnosis and inappropriate treatment.
CONCLUSION
PHPT must be considered as a differential diagnosis for multiple osteolytic bone lesions. Diagnosis can be aided by a thorough clinical examination, including an assessment for neck swelling, and laboratory testing of serum calcium levels and PTH levels. Surgical excision of the hyperactive gland serves as the definitive treatment for this condition, with bony lesions regressing gradually over time.

BACKGROUND
Dry socket (DS) or fibrinolytic osteitis is a relatively common complication that can occur following tooth extraction. This study aimed to determine the prevalence of DS and identify its associated predictive and mediating variables.
MATERIAL AND METHODS
This study is classified as prospective observational, cross-sectional, and multicenter. Patients were consecutively selected in accordance with established criteria for tooth extraction. Data on patient demographics, surgical procedures and postoperative outcomes were collected. Nominal variables were analyzed using the Chi-Square Test, while associations involving ordinal values or considering counts or layers were examined using the Kendall's Tau-B Test or Mantel-Haenszel Test for trend. The GLM Mediation Model was employed to investigate potential mediation or indirect effects or potential underlying mechanisms of predictive variables on the development of DS. Two-tailed significance level of p ≤0.05 was considered statistically significant.
RESULTS
A total of 1,357 patients undergoing routine dental extractions were included. DS was observed in 13 patients (prevalence of 1%). DS was associated with younger patients (under 50 years old), longer procedures, and the presence of surgical accidents, but only when mediated by surgical complexity. Smoking, particularly in combination with complex surgeries and surgical accidents, was associated with DS. Postoperative pain for more than two days and reported at moderate to high levels, emerged as a potential warning sign for DS. The use of antibiotics was found to significantly reduce the risk of DS (RR reduction of 36% and absolute risk reduction of 0.63%).
CONCLUSIONS
Routine dental extractions revealed a 1% prevalence of dry socket. The obtained results suggests that DS is a multifactorial condition influenced by various factors, including gender, age, smoking, antibiotic prescription and surgical factors such as length, technique and accidents, nevertheless, those associations were observed mainly considering the influence of one variable on another.

BACKGROUND
Sri Lanka after eliminating malaria in 2012, is in the prevention of re-establishment (POR) phase. Being a tropical country with high malariogenic potential, maintaining vigilance is important. All malaria cases are investigated epidemiologically and followed up by integrated drug efficacy surveillance (iDES). Occasionally, that alone is not adequate to differentiate Plasmodium falciparum reinfections from recrudescences. This study evaluated the World Health Organization and Medicines for Malaria Venture (MMV) recommended genotyping protocol for the merozoite surface proteins (msp1, msp2) and the glutamate-rich protein (glurp) to discriminate P. falciparum recrudescence from reinfection in POR phase.
METHODS
All P. falciparum patients detected from April 2014 to December 2019 were included in this study. Patients were treated and followed up by iDES up to 28 days and were advised to get tested if they develop fever at any time over the following year. Basic socio-demographic information including history of travel was obtained. Details of the malariogenic potential and reactive entomological and parasitological surveillance carried out by the Anti Malaria Campaign to exclude the possibility of local transmission were also collected. The msp1, msp2, and glurp genotyping was performed for initial and any recurrent infections. Classification of recurrent infections as recrudescence or reinfection was done based on epidemiological findings and was compared with the genotyping outcome.
RESULTS
Among 106 P. falciparum patients, six had recurrent infections. All the initial infections were imported, with a history of travel to malaria endemic countries. In all instances, the reactive entomological and parasitological surveillance had no evidence for local transmission. Five recurrences occurred within 28 days of follow-up and were classified as recrudescence. They have not travelled to malaria endemic countries between the initial and recurrent infections. The other had a recurrent infection after 105 days. It was assumed a reinfection, as he had travelled to the same malaria endemic country in between the two malaria attacks. Genotyping confirmed the recrudescence and the reinfection.
CONCLUSIONS
The msp1, msp2 and glurp genotyping method accurately differentiated reinfections from recrudescence. Since reinfection without a history of travel to a malaria endemic country would mean local transmission, combining genotyping outcome with epidemiological findings will assist classifying malaria cases without any ambiguity.

BACKGROUND
The aim of our study is to evaluate the postoperative complications after the extraction of impacted third molar teeth and to investigate the effects of these complications on the quality of life of patients.
METHODS
Demographic, clinical, and radiological evaluations were conducted, covering factors like age, gender, and tooth position. Clinical measurements, pain and edema assessments, and quality of life evaluations through OHIP-14 scores were performed. Preoperative and postoperative mouth opening, trismus, alveolitis and dehiscence were evaluated.
RESULTS
A total of 100 patients were included in our study. No significant gender-based differences were found in measurements, pain, or swelling. There was no statistically significant difference between the preoperative and postoperative results of difference A-C, difference B-E, difference A-D, and difference mouth opening. Procedure duration correlated positively with age, alveolar osteitis, trismus, and swelling. Postoperative quality of life, assessed by OHIP-14, demonstrated a negative correlation with age and trismus. It was observed that the gender and the tooth positions of the patients had no effect on the severity of postoperative pain and edema.
CONCLUSIONS
As the age of the patients increases and the duration of the procedure increases, the rate of postoperative complications increases and it is concluded that the quality of life decreases significantly.

BACKGROUND
Inflammation around the tendons of interosseous muscles of the hand (interosseous tendon inflammation) was recently observed with MRI for the first time in patients with rheumatoid arthritis and in at-risk individuals with detectable anti-citrullinated protein antibodies, generating the hypothesis that interosseous tendon inflammation precedes clinical arthritis. To better understand the role of interosseous tendon inflammation during the development of rheumatoid arthritis, we studied the frequency of interosseous tendon inflammation in healthy individuals and in those with arthralgia that was suspected of progressing to rheumatoid arthritis (ie, clinically suspect arthralgia) and the association of interosseous tendon inflammation with other symptoms of inflamed joint tissues and with clinical arthritis development.
METHODS
Adult (age ≥18 years) patients who presented with clinically suspect arthralgia and symptom-free (control) individuals underwent contrast-enhanced hand MRI. MRIs were evaluated for interosseous tendon inflammation on the radial and ulnar sides of the second to fifth metacarpophalangeal joints, and for synovitis, tenosynovitis, and osteitis using the rheumatoid arthritis MRI scoring system. Patients with clinically suspect arthralgia were followed up for clinical arthritis development. The presence of local tenosynovium was examined using immunohistochemistry for anti-CD55 and anti-CD68 on tissue from the hands of three embalmed bodies donated for scientific research. The primary outcome for the cross-sectional part of the study was the presence of interosseous tendon inflammation on MRI. The primary outcome for the longitudinal part of the study was development of clinical arthritis.
FINDINGS
Between April 3, 2012, and May 20, 2020, 667 patients with clinically suspect arthralgia (mean age 44 years [SD 13], 504 [76%] were women and 163 [24%] were men) underwent contrast-enhanced hand MRI. Between Nov 1, 2013, and Nov 30, 2014, 193 symptom-free controls were recruited (mean age 50 years [SD 16], 136 [70%] were women and 57 [30%] were men). Two (1%) of 193 symptom-free controls had interosseous tendon inflammation. Immunohistochemistry of cadaveric hand tissues showed no tenosynovium surrounding interosseous tendons. At inclusion, 67 (10%) of 667 patients with clinically suspect arthralgia had interosseous tendon inflammation (p<0·0001 vs symptom-free controls). Interosseous tendon inflammation occurred more frequently if synovitis (odds ratio [OR] 2·2 [95% CI 1·2-4·2]), or tenosynovitis (OR 9·7 [5·5-17·0]), was present at metacarpophalangeal joints. A three-dimensional MRI reconstruction suggested confluency of interosseous tendon inflammation with metacarpophalangeal-flexor-tenosynovitis. 91 (16%) of 558 patients with clinically suspect arthralgia developed clinical arthritis during follow-up (median total follow-up 25·3 months [95% CI 25·1-25·5]). Patients with clinically suspect arthralgia with interosseous tendon inflammation had a higher risk of developing clinical arthritis (hazard ratio [HR] 4·5 [2·8-7·2]), which was attenuated but still significant after adjusting for concomitant synovitis, tenosynovitis, or osteitis (HR 1·7 [1·02-2·8]).
INTERPRETATION
Interosseous tendon inflammation is almost absent in symptom-free individuals but occurs in people with clinically suspect arthralgia, in whom it correlates with symptoms and is associated with the development of clinical arthritis. The absence of local tenosynovium suggests that interosseous tendon inflammation arises from expanding local subclinical inflammation in the pre-arthritis phase of rheumatoid arthritis.

Introduction Oral and maxillofacial surgeons frequently perform the removal of impacted mandibular third molars. The success of this surgical intervention depends on meticulous surgical technique and the use of appropriate irrigants to minimize complications in the postoperative period. Aim The aim of this study was to evaluate the efficacy of four different irrigation solutions (povidone-iodine, metronidazole, chlorhexidine gluconate (CHX), and normal saline) on postoperative sequelae like pain, trismus, swelling, and alveolar osteitis following surgical extraction of the impacted mandibular third molars. Materials and methods The current research was a randomized study carried out at Saveetha Dental College and Hospital in Chennai, India, from December 2022 to March 2023. The study population consisted of 112 participants who were referred to the Oral and Maxillofacial Surgery for the surgical removal of impacted mandibular third molars. The population was divided into four groups, with 28 in each group. They were categorized as A, B, C, and D based on the final irrigation solution used after surgical removal of the impacted teeth. In group A, patients received 0.5% povidone-iodine as the final irrigation solution; group B received 1% metronidazole; group C received 0.12% chlorhexidine gluconate (CHX); and group D received 0.9% normal saline. Patients were examined on the first and seventh postoperative days to assess pain, swelling, trismus, and alveolar osteitis. The results were analyzed with SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, United States) software for Windows (Microsoft Corporation, Redmond, Washington, United States). A p-value less than 0.05 was considered statistically significant. Results Group B experienced significantly less pain than groups A, C, and D on the first and seventh postoperative days (p<0.05). The facial swelling was significantly less on the first and seventh postoperative day in group B compared to groups A, B, and D (p<0.05). There was no statistically significant variation observed in trismus (mouth opening) across the groups on both the first postoperative and seventh postoperative days. The presence of alveolar osteitis was seen in groups A, C, and D, but no instances were reported in group B. Conclusion It can be concluded that among the four irrigation solutions used in the lower third molar surgery, metronidazole irrigation solution yielded the best results in terms of less pain, swelling, and alveolar osteitis followed by chlorhexidine. There was no difference between povidone-iodine irrigation and normal saline irrigation on the postoperative sequelae. Postoperative trismus does not depend on the irrigation solution used in the third molar surgery.

OBJECTIVE
Conventional magnetic resonance imaging (MRI) uses T1-weighted and short-tau inversion recovery (STIR) sequences to characterize bone marrow in axial spondyloarthritis. However, quantification is restricted to estimating the extent of lesions because signal intensities are highly variable both within individuals and across patients and MRI scanners. This study evaluates the performance of quantitative T1 mapping for distinguishing different types of bone marrow lesions of the sacroiliac joints.
MATERIALS AND METHODS
In this prospective study, 62 patients underwent computed tomography (CT) and MRI of the sacroiliac joints including T1, STIR, and T1 mapping. Bone marrow lesions were characterized by three readers and assigned to one of four groups: sclerosis, osteitis, fat lesions, and mixed marrow lesions. Relaxation times on T1 maps were compared using generalized estimating equations and receiver operating characteristics (ROC) analysis.
RESULTS
A total of 119 lesions were selected (sclerosis: 38, osteitis: 27, fat lesions: 40; mixed lesions: 14). T1 maps showed highly significant differences between the lesions with the lowest values for sclerosis (1516±220 ms), followed by osteitis (1909±75 ms), and fat lesions (2391±200 ms); p<0.001. T1 mapping differentiated lesions with areas under the ROC curve of 99% (sclerosis vs. osteitis) and 100% (other comparisons).
CONCLUSION
T1 mapping allows accurate characterization of sclerosis, osteitis, and fat lesions at the sacroiliac joint but only for homogeneous, non-mixed lesions. Thus, further sequence development is needed before implementation in clinical routine.
