Background: Patients with rheumatoid arthritis (RA) may have more prevalent and severe periodontitis than healthy controls. Periodontitis may increase the systemic inflammation in RA. The aim of this study is to assess periodontitis prevalence and severity and its potential association with systemic inflammation in Indonesian patients with RA.Methods: A full‐mouth periodontal examination including probing depth, gingival recession, plaque index, and bleeding on probing was performed in 75 Indonesians with RA and 75 age‐, sex‐, and smoking‐matched Indonesian controls. A validated questionnaire was used to assess smoking, body mass index, education, and medical conditions. In addition, in all participants, the use of drugs was noted, and erythrocyte sedimentation rates and serum levels of high‐sensitivity C‐reactive protein (hsCRP), rheumatoid factor, and anti‐citrullinated protein antibodies were measured. Differences in periodontitis prevalence and 12 measures of periodontitis severity between patients with RA and controls were analyzed using univariate analyses.Results: No significant differences in periodontitis prevalence and 11 measures of periodontitis severity between patients with RA and controls were observed. Conversely, patients with RA had a significantly lower surface area of healthy pocket epithelium versus controls (P = 0.008), and a tendency toward higher hsCRP levels was observed in patients with RA with severe periodontitis compared with patients with RA with no mild or moderate periodontitis (P = 0.063). It has to be noted that all patients with RA were on anti‐inflammatory drugs, whereas none of the controls used such drugs.Conclusion: Prevalence and severity of periodontitis in Indonesian patients with RA is comparable to controls but with less healthy pocket epithelium than in controls and a tendency toward a higher inflammatory state in patients with RA and severe periodontitis.

Expectant management of preterm preeclampsia is a realistic option in a major Indonesian perinatal referral center. Steroids (outside the use for fetal lung maturation) should not be used in the expectant management of preterm preeclampsia in Indonesia.

Aim:  To determine the risk factors of symptomatic osteoarthritis (OA) of the knee.Methods:  Two hundred and thirty‐nine cases of symptomatic OA of the knee (ACR Criteria for OA 1986) with radiographic OA (Kellgren‐Lawrence I or more) taken from a rheumatology outpatient clinic were compared to 279 controls without radiographic (Kellgren‐Lawrence 0) OA taken from general internal medicine outpatient clinic at the same hospital. Independent variables to be assessed were age, sex, ethnic group, body mass index (BMI), education, marital status, parity, smoking, and history of acute trauma, hysterectomy, anatomical abnormality of knee, diabetes mellitus, and uric acid levels. Multiple logistic regression analysis was done to assess the independent risk factors.Results:  After going through the steps of multiple logistic regressions analysis, the results were: symptomatic cases compared to controls: age > 50 (OR: 1.86, 95% CI = 1.78–2.82), being female (OR: 2.08, 95% CI = 1.35–3.50), BMI > 25 units (OR: 3.28, 95% CI = 2.20–4.89), elementary education (OR: 0.29, 95% CI = 0.14–0.61) and genu valgus (OR: 4.07, 95% CI = 2.43–7.93). For the female subset of symptomatic cases compared with controls: age > 50 (OR: 9.34, 95% CI = 4.77–18.24), BMI > 25 units (OR: 5.27, 95% CI = 2.85–9.73) and genu valgus (OR: 13.64, 95% CI = 4.58–41.44).Conclusions:  Age > 50, being female, BMI > 25 units and genu valgus, may be the risk factors for symptomatic OA of the knee.

In previous studies, Zingiber officinale, Piper retrofractum, and the combination showed cytotoxic activity, induced apoptosis, and p53 expression of HeLa, T47D, and MCF-7 cell lines. This study was conducted to investigate the cytotoxic and apoptotic activity of Zingiber officinale (ZO), Piper retrofractum (PR), and the combination as well as their effect to p53 expression on Myeloma and WiDr cells. The powder of ZO, PR, and ZO + PR combination (1:1) were macerated with 96% ethanol for 3 x 24 hours. MTT cytotoxic assay was performed on Myeloma and WiDr cell lines. Apoptotic cells were stained with ethidium bromide and acridine orange. Imunohistochemical expression of p53 was examined on Myeloma and WiDr cell lines. Doxorubicin was used as positive control in all assays. Results showed that ZO, PR, and ZO + PR combination had cytotoxic activity on Myeloma cells with IC 50 of 28, 36, and 55 mg/ml respectively and WiDr cell lines with IC 50 of 74, 158, and 64 mg/ml respectively, induced apoptotic activity, and increased p53 expression on Myeloma and WiDr cells. These results suggest that ZO, PR, and their combination induced Myeloma and WiDr cells in apoptosis through p53 expression.
