Impact of Previous Ankle Injuries on Professional Footballers' Preseason Functional Ankle Assessment

Introduction

Football is the most popular sport and is widely played around the globe, with approximately 400 million players in 208 countries. Lower extremity injuries showed the highest incidence, with ankle injuries being the most prevalent after hip and knee injuries. The purpose of this study was to describe the characteristics of the players who reported previous ankle injuries during pre-competition medical assessment (PCMA) during the 2022 seasons of the Malaysian professional club. In addition, the study also investigated the effect of previous injuries on current ankle function.

Materials and methods

This was a retrospective cross-sectional study using secondary data from the preseason PCMA data from a professional club that competed in Malaysia. The ankle range of motion, anterior drawer test, and functional ankle assessments including the Biodex athlete single leg stability test and ankle joint muscle strength were performed during the PCMA.

Results

A total of 45 footballers reported previous history of ankle injuries to the left (n=9), right (n=20), or both ankles (n=16). Footballers with prior ankle injuries exhibited significantly less ankle inversion (p = 0.008) and a larger proportion of positive ADT tests in the injured ankle (x2(1, N=90) =7.76, p=0.005) compared to the non-injured side. there was no significant difference in other ankle range of motion, ankle stability index, or ankle muscular strength between previously injured and uninjured ankles.

Conclusions

During preseason screening, half of the footballers in this study reported previous history of ankle injury, putting them at risk of having future ankle injuries. Aside from inversion and the anterior drawer test, no significant differences in range of motion, stability index, or muscle strength were discovered. However, as injury causation is multifactorial, preventive measures should be taken to reduce the risk of injury.

Association Between Candida albicans and COVID-19 in Complete Denture Wearers: An Observational Study

Introduction The phenomenon of coronavirus disease 2019 (COVID-19)-related candidiasis is gaining increased attention and acknowledgment as an integral component of the severe consequences of COVID-19. The aim of the present study was to assess the association between Candida albicans and COVID-19 in complete denture wearers. Materials and methods An observational study was conducted on 45 complete denture wearers, who were divided into three groups as follows: Group 1, 15 subjects with mild to moderate COVID-19 infection; Group 2, 15 subjects with severe COVID-19 infection; and Group 3, 15 subjects without COVID-19 infection. Mean colony forming units (CFU) were observed on agar plates containing Sabouraud dextrose in the salivary samples of the participants. Analysis of variance, followed by post-hoc analysis by Tukey's test, was used to compare CFU between the groups. Pearson's correlation coefficient was used to study the correlation between variables. Results The highest average colony-forming units of Candida albicans were observed in Group 2, followed by Group 1, compared to the control group, and a significant (p<0.001) difference was found. A weak positive correlation was found between the age of the patients and the duration of denture usage, as well as between age and the counts of Candida albicans in Groups 1 and 3. This correlation was more pronounced in Group 3. A strong positive correlation was observed in all groups between the Candida albicans count and the duration of denture usage by the patients. Conclusion The association between Candida albicans and denture wear was compounded by the presence of COVID-19. Consequently, the timely identification of Candida albicans infection in patients with COVID-19 is important to establish more efficacious approaches for antifungal treatment and prophylactic interventions.

Effect of Chronic Apical Periodontitis in Primary Molars on Succedaneous Permanent Teeth: An Observational Retrospective Study

INTRODUCTION

Periapical infection of primary molars affects the development of permanent teeth (premolars). Therefore, the present study was conducted to test the null hypothesis in children aged 4-10 years with chronic apical periodontitis (CAP) of the primary molars.

MATERIALS AND METHODS

A retrospective, cross-sectional study was conducted on 185 panoramic radiographs of healthy children aged 4-10 years with CAP in the primary molars. A total of 256 infected primary molars (144 teeth in females, 112 teeth in males) were analyzed, radiographically, and compared with 245 healthy primary molars on the contralateral side. Permanent successors were evaluated for follicular damage, maturation, morphology, and deviation in the eruption path. Primary molars were evaluated for root resorption. Sixteen permanent teeth on the affected side and five teeth on the control side were excluded due to abnormal development. Student's t-test and the chi-square test were used to analyze the data.

RESULTS

The null hypothesis is rejected. There were significant differences in the developmental status of permanent successors on the affected side, compared to the normal side at four to seven years (p<0.05). There were no significant sex differences in the abnormalities of permanent successors on the affected side (p>0.05). As the root resorption of the primary molars increased, the follicular damage observed in the permanent successors also increased (p<0.05), which suggests that, as the infection of primary molars increases, more damage is caused to underlying permanent successors (premolars).

CONCLUSION

Apical periodontitis of the primary molars retards the development of permanent successors (premolars), affects their shape, causes follicular damage, and alters the eruption path.

Pulmonary complications in diabetes mellitus

Diabetes mellitus is a chronic debilitating and devastating disease, which affects various organs including lungs. The incidence and prevalence of diabetes mellitus and its complications is increasing day by day. Many studies have reported different pulmonary complications in diabetic patients. Chronic hyperglycemia causes non-enzymatic glycation of the chest wall and bronchial tree collagen protein that leads to fibrous tissue formation. Due to increased protein catabolism, there is decreased respiratory muscle strength. Neuropathy of phrenic nerve may cause diaphragmatic paralysis. So, the diabetes mellitus causes reduced ventilatory function. The disease also causes thickening of the basal lamina by glycation and reduces the gas diffusing capacity. It also causes glycation of immunoglobulin and increases the chance of acute and chronic pulmonary infections that causes fibrosis of lung parenchyma and consequently reduces the lung mechanics. Hyperglycemia causes local biochemical changes in the lungs and reduces the antioxidant defense of the lungs. The consequence of the local oxidative stress reduces the lung volumes, elastic recoil of the lungs and also causes reduced bronchodilatation. So, diabetes mellitus plays a significant role in development of pulmonary complication and like other organs lungs are the target organ in diabetes mellitus.

Upper abdominal mass with diagnostic dilemma

A 32 years old gentleman presented with a lump occupying the epigastric, left hypochondriac and umbilical region for the last 3 months which gradually increased in size & dull aching pain. He also complained of low grade fever and early satiety. On examination, he had a lump on upper abdomen which was irregular, firm, mildly tender, lobulated surface, restricted mobility, dull on percussion. USG examination of HBS revealed hepatomegaly and SOL in liver. CT abdomen revealed soft tissue mass in left upper abdomen. FNA revealed cells of mesenchymal origin. Per operatively a large lobulated, myxomatous highly vascular mass arising from the fundal part of the stomach was found and removed. Histopathology report comments about two differential diagnosis-leiomyosarcoma and gastrointestinal stromal tumour. CD117 immunostaining confirmed it was gastrointestinal stromal tumor (GIST). Post operatively patient was treated by Imatinib and is now under regular follow up.
