BACKGROUND: Non traumatic osteonecrosis also known as  avascular necrosis (AVN),and tuberculous arthritis (TB    arthritis)most commonly present as chronic monoarticular conditions. Corticosteroid intake is known to predispose individuals to the development of these two conditions.                      
In AVN, corticosteroid remains to be the most common cause that leads to a final  common pathway of disrupting    blood supply to segments of bone causing cell death. In TB arthritis, corticosteroid renders  a patient relatively immunocompromised predisposing to this extrapulmonary infection.                                                                                                                                                         
The incidence of tubercular osteonecrosis in a patient with systemic lupus erythematosus is rare. A review of literature only showed one case report of tubercular osteonecrosis diagnosed by aspiration cytology. Since tuberculosis (TB) is a destructive but curable disease, early diagnosis  and  treatment  are essential.
OBJECTIVE: To present a case of tubercular osteonecrosis in a patient with systemic lupus erythematosus treated with anti-Koch's regimen and iloprost infusion.
CASE: A 27-year old Filipino female who was diagnosed with lupus nephritis and underwent three days  methylprednisolone pulse therapy. Lupus nephritis improved  and  was clinically inactive for two years. She  developed insidious onset of intermittent pain on her left knee, associated with swelling for four months with  subsequent right hip pain of one week duration. MRI of the left knee showed osteonecrosis and arthritis. Radiograph of the right hip showed osteonecrosis. She underwent arthrocentesis of the left knee and the synovial  fluid tested positive for tuberculosis by PCR. We started the patient on quadruple anti-Koch's regimen together with iloprost infusion which afforded clinical improvement. 
CONCLUSION: To our knowledge, this is the first reported case of a lupus patient with concomitant polyarticular osteonecrosis complicated by monoarticular tuberculous arthritis. Medical treatment, while it may be complicated by adverse drug events, is effective in symptomatic treatment, but a multidisciplinary approach is suggested for optimal outcome.

Objectives: Recent studies show that patients with young-onset gout present with visible tophi or nephrolithiasis on diagnosis. In the Philippines, where gout is prevalent, there is no published work on this subset of patients. This study presents the clinical characteristics of a cohort of Filipino patients with gout whose symptoms started at 30 years of age or younger. Methods: The case records of all patients who fulfilled the 1977 American College of Rheumatology (ACR) criteria for gout seen in four adult rheumatology services were reviewed. We selected those whose age of onset of gout was at 30 years or younger. The demographic characteristics, medical history, laboratory parameters, and presenting manifestations were described. Results: Six hundred sixty-nine records of patients with gout were reviewed; 101 (15%) fulfilled the young-onset gout criteria. The mean age of onset was 25±4.40 years (range 14-30), and the mean disease duration before diagnosis was 12.64±11.91 years. All of the patients were male and most were married; 76% were alcoholic beverage drinkers and 38% were smokers. A family history of gout was noted in 47%. Most patients (66%) were already on nonsteroidal anti-inflammatory drugs (NSAIDs), 24% on colchicine, and 14% on urate-lowering therapy before consult at the rheumatology clinic. By history, at onset, the most common pattern of joint involvement was monoarthritis (95%), affecting the ankles (60%), knees (52%), and 1st metatarsophalangeal (MTP) joint (51%). However, on the first rheumatology clinic visit, 34% of arthritis was polyarticular, more than 68% had more than three arthritis attacks per year, and there were tophi in 35%. The mean duration before visible tophi formation was 2.81±6.75 years. Around 21% had nephrolithiasis or a history thereof. The mean serum uric acid (SUA) was 9.18 mg/dL and the mean serum creatinine was 1.5 mg/dL. Thirty-seven percent had estimated glomerular filtration rate (GFR) <60 mL/min. Conclusion Young-onset gout was present in 15% of our patients and gout was familial in 47%. There was a delay in diagnosis of as long as ten years in most of the patients. On presentation at the rheumatology clinic, more than 34% had polyarticular arthritis, 35% had tophi, and 37% had low estimated GFR. This emphasizes the importance of awareness and prompt diagnosis to ensure correct treatment and prevention of complications

Introduction: Cognitive impairment (CI) in patients with systemic lupus erythematosus (SLE) presents with or without overt signs of central nervous involvement. The prevalence of CI is variable, ranging from 19-80%. It is often overlooked, leading to high healthcare costs and productivity loss. The usual tools for detection are expensive, time-consuming and not locally available. Detection of CI using the Mini Mental State Examination (MMSE) and Montreal Cognitive Assessment Test (MoCA) is more clinically relevant and practical. The objectives of this study are to determine the prevalence of CI in SLE patients using MMSE/MoCA, to determine the degree of impairment in the different cognitive domains, and to characterize patients with CI in terms of disease activity, education, and employment. Methods: This is a cross-sectional study of 62 SLE patients, 19 years or older, at a rheumatology clinic. Demographic and disease characteristics were collected. The validated Filipino versions of the MMSE/MoCA test were administered. Descriptive and non-parametric statistics were applied. Results: Most patients are female (96.77%), below collegiate level of education (58.06%), and unemployed (70.97%). Mean disease duration is 8.92 (SD±7.03) years. Mean age at diagnosis is 28 (SD±10.30) years. Hypertension is the most common co-morbidity. Most have low lupus disease activity or are in remission (80.65%). Most are on prednisone (72.58%), with an average dose of 11.88mg/day (SD±10.66). The prevalence of CI is 38.71% (MMSE-P) and 77.42% (MoCA-P). The presence of CI is not related to educational level, employment, and disease activity. Conclusion Cognitive impairment (CI) is common in this cohort of SLE patients. Disease activity, level of education and employment do not seem to affect its occurrence. The MMSE-P and MoCA-P are rapid tools to assess the presence of CI and should be used in clinical practice to improve the quality of care for patients with lupus.
