Epidemiology and Factors Affecting Functional Outcome of Distal Radial Fracture in an Urban Tertiary Medical Centre in Malaysia

@#Introduction: Distal radial fracture is a commonly encountered fracture. This study aims to study the epidemiology of distal radial fracture and factors affecting the patients’ functional outcome one to two years after the injury. Materials and methods: This is a retrospective cohort study. The records of patients, fulfilling the radiographical diagnosis of distal radial fracture, and aged 18 and above, who presented to our Emergency Department from 1st January 2018 to 31st December 2018 were retrieved. According to AO classification, we grouped our patients into A (extra-articular), B (partial articular) and C (complete articular). Patients with congenital abnormalities were excluded. Epidemiological data and relevant medical history were obtained and tabulated. A Malaysian language translation of Disability of the Arm, Shoulder and Hand (DASH) questionnaire was used to assess the functional outcome. Results: Out of 168 patients’ data retrieved, only 110 patients’ data were found complete for purposes of this study. The mean DASH score was 13.7 ± 7.87 approximately one to two years post-injury regardless of treatment method. Increasing age was associated with higher DASH score with r=0.407(p<0.001). Several variables had significantly better functional outcome: male gender (p=0.01), Type A fracture configuration (p=0.007) and non-operational treatment (p=0.03). There was no significant difference between treatment modalities in Type A fracture (p=0.094), but Type B (p=0.043) and Type C (p=0.007) had better outcome without surgery. There was no significant difference between different ethnic groups, open or closed fracture and mechanism of injury. Conclusion: Better functional outcome after sustaining distal radial fracture was associated with young age, male gender, type A fracture and treated non-operatively. Interestingly, more complex fracture pattern had better functionality were observed without surgery.

MiR-218 suppresses metastasis and invasion of endometrial cancer via negatively regulating ADD2.

OBJECTIVE: Endometrial cancer (EC) is one of the three most common gynecological cancers. Due to the lack of effective treatment for EC patients in an advanced stage, the mortality rate of EC is increasing rapidly. Hence, it is essential to seek for novel molecular therapeutic targets and biomarkers for EC. The aim of this study was to explore the role of miR-218 in the occurrence and development of EC and to investigate the possible underlying mechanism. PATIENTS AND METHODS: The expression level of miR-218 in EC tissues and cell lines was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Wound healing assay and Matrigel assay were performed to determine the migration and invasion abilities of EC cells. Meanwhile, the potential targets of miR-218 were predicted by bioinformatics analysis and confirmed by Luciferase reporter gene assay. In addition, the protein expression level of Adducin 2 (ADD2) was assessed by Western blotting analysis. RESULTS: QRT-PCR results revealed that miR-218 was significantly downregulated in EC tissues and cell lines. Wound healing assay and Matrigel assay demonstrated that miR-218 suppressed the migration and invasion abilities of EC cells. Online prediction databases predicted that ADD2 was a direct target of miR-218, which was verified by Luciferase reporter gene assay. Rescue experiments further validated that miR-218 could serve as a carcinoma suppressor by negatively regulating ADD2 expression in EC. CONCLUSIONS: In the present study, we elucidated that miR-218 served as a tumor suppressor in EC by negatively regulating ADD2. This might bring a novel insight into new molecular therapeutic targets and biomarkers for EC.

Expressions of VEGF and miR-21 in tumor tissues of cervical cancer patients with HPV infection and their relationships with prognosis.

OBJECTIVE: To investigate the expressions of vascular endothelial growth factor (VEGF) and micro-ribonucleic acid-21 (miR-21) in cervical cancer patients with human papillomavirus (HPV) infection and determine the potential relationships with prognosis. PATIENTS AND METHODS: Expressions of VEGF in cervical cancer tissues and cancer-adjacent tissues were detected by immunohistochemistry, and the expressions of miR-21 and VEGF in both tissues were quantitatively analyzed using reverse transcription polymerase chain reaction (RT-PCR). Patients with cervical cancer were followed up after operation, and the survival rates of patients with different expression levels of miR-21 and VEGF were compared. RESULTS: VEGF was expressed in both cervical cancer tissues and cancer-adjacent tissues. The positive expression rate of VEGF in cervical cancer tissues (75.69%) was significantly higher than that in cancer-adjacent tissues (10.45%). RT-PCR results showed that the expression levels of miR-21 and VEGF in cervical cancer tissues were significantly higher than those in cancer-adjacent tissues (p<0.05). Correlation analyses revealed that miR-21 expression was significantly positively correlated with VEGF expression in cervical cancer tissues (r2=0.4174, p<0.0001). Prognostic analyses showed that the 5-year survival rate of patients was relatively high when miR-21 and VEGF were lowly expressed. CONCLUSIONS: VEGF and miR-21 are highly expressed in tumor tissues of cervical cancer patients with HPV infection. VEGF expression is significantly positively correlated with miR-21 expression, and the high levels of VEGF and miR-21 predict unfavorable prognosis of cervical cancer. Data provide a theoretical support for clinical treatment of cervical cancer patients with HPV infection.

A clinical appraisal of adult psoriasis patients in Serdang Hospital

Objectives To determine the socio-demographic profile, clinical characteristics and quality of life of adult psoriasis patients as well as the association between the first two variables with the latter. Methods A cross-sectional study of 30 adult psoriasis patients was conducted in the Dermatology Clinic, Serdang Hospital from 9th to 23rd May 2011. A questionnaire regarding clinical data containing multilingual Dermatology Life Quality Index (DLQI) was used in a face-to-face interview. Results Male-to-female ratio was 1:1.5. Psoriasis was more common in Malays (76.7%) compared to Chinese (10%) and Indians (10%), however this ethnic distribution was proportionate to that of the clinic attendance. The onset of psoriasis was during the second to third decade of life in most patients (53.3%) with a mean of 31 years (range 7 - 62). Nine (30%) patients had positive family history of psoriasis. The main aggravating factors were stress and sunlight. Hyperlipidemia was the commonest associated co-morbidity. Plaque psoriasis was the commonest clinical type (66.7%) and majority (66.7%) had <10% body surface area affected. Nail changes were present in 15 (50%) patients and psoriatic arthropathy occurred in 11 (36.7%), with mono/oligoarticular type being as common as symmetrical polyarthropathy. All patients were treated with topical therapy, six were on systemic medication and only one underwent phototherapy. The mean DLQI score was 10.77 ± 6.22. The duration of disease and the age group were negatively correlated with the DLQI scores (r= -0.45 and -0.42 respectively, p < 0.05). Conclusion The clinical findings are similar to previous local studies and are valuable to improve patient care.
