Pathological lesions in and around a joint can arise
from underlying dermis, subcutis, deep muscle, bone or
synovium. Clinical presentation can include joint pain,
joint swelling, palpable masses and mechanical restriction.
Whilst giant cell tumour of tendon sheath, pigmented
villonodular synovitis, synovial chondromatosis, lipoma
arborescens, juxta articular myxomas and inflammatory
arthritis are the better-known conditions of the joint.
Intra-articular nodular fasciitis, on the other hand, is less
well recognized both clinically and radiologically. It is
rarely seen in routine practice and is only described in case
reports in the literature. Due to the non-specific clinical
and radiological findings as well as the unfamiliarity with
the entity, the diagnosis of intra-articular nodular fasciitis
is usually clinched only after histological examination.
We present a case of intra-articular nodular fasciitis arising
in the knee joint which was not suspected clinically or
radiologically

Among many reported applications of detection of antibodies to phenolic glycolipid-I (PGL-I) of Mycobacterium leprae, seroprevalence may turn out to be very useful as an indicator of the magnitude of leprosy problem in its control program. Recently, simple tests for the detection of antibodies to PGL-I have been developed. As an effort to assess meaning of qualitative test for anti-PGL-I antibodies, we compared enzyme-linked immunosorbent assay (ELISA) and an immunochromatographic assay (ICA) using PGL-I neoglycoconjugate antigens for detection of antibodies in sera from 165 leprosy patients and 746 healthy controls. The upper limit of normal control O.D. in ELISA was 0.236, and the sensitivity of ICA was 56.4%, and its specificity was 93.9%.

Objective:
To investigate variations in the effects of prehospital advanced airway management (AAM) on outcomes of out-of-hospital cardiac arrest (OHCA) patients according to regional emergency medical service (EMS) systems in four Asian cities.
Methods:
We enrolled adult patients with EMS-treated OHCA of presumed cardiac origin between 2012 and 2014 from Osaka (Japan), Seoul (Republic of Korea), Singapore (Singapore), and Taipei (Taiwan). The main exposure variable was prehospital AAM. The primary endpoint was neurological recovery. We compared outcomes between the prehospital AAM and non-AAM groups using multivariable logistic regression with an interaction term between prehospital AAM and the four Asian cities.
Results:
A total of 16,510 patients were included in the final analyses. The rates of prehospital AAM varied among Osaka, Seoul, Singapore, and Taipei (65.0%, 19.2%, 84.9%, and 34.1%, respectively). The non-AAM group showed better outcomes than the AAM group (adjusted odds ratio [aOR] for neurological recovery 0.30; 95% confidence interval [CI], 0.24–0.38]). In the interaction model for neurological recovery, the aORs for AAM in Osaka and Singapore were 0.12 (95% CI, 0.06–0.26) and 0.21 (95% CI, 0.16–0.28), respectively. In Seoul and Taipei, the association between prehospital AAM and neurological recovery was not significant (aOR 0.58 [95% CI, 0.31–1.10] and 0.79 [95% CI, 0.52–1.20], respectively). The interaction between prehospital AAM and region was significant (P=0.01).
Conclusion
The effects of prehospital AAM on outcomes of OHCA patients differed according to regional variability in the EMS systems.

BACKGROUND/AIMS: To examine the association between use of oral contraceptive pills (OCPs) and the risk of developing inflammatory bowel diseases (IBD), in a modern cohort. METHODS: A prospective nested case-control study across sites in the Asia-Pacific region was conducted; involving female IBD cases and asymptomatic controls. Subjects completed a questionnaire addressing questions related to OCP use. Primary outcome was the risk of development of IBD of those exposed to OCP versus non-exposure. Secondary outcomes were development of Crohn's disease (CD) versus ulcerative colitis (UC), and whether age of first use of OCP use may be associated with risk of IBD. RESULTS: Three hundred and forty-eight female IBD cases (41% CD, median age: 43 years) and 590 female age-matched controls were recruited. No significant association was found between OCP use and the risk of IBD (odds ratio [OR], 1.65; 95% confidence interval, 0.77–3.13; P=0.22), CD (OR, 1.55) or UC (OR, 1.01). The lack of association persisted when results were adjusted for age and smoking. IBD cases commenced OCP use at a younger age than controls (18 years vs. 20 years, P=0.049). CONCLUSIONS: In this large cohort of subjects from the Asia-Pacific region, we found a modest but not significantly increased risk of developing IBD amongst OCP users.

Introduction: Sarawak has a population that is
geographically and characteristically widely varied. This
study aimed to determine the demographic profile of
patients in Sarawak, Malaysia.
Materials and Methods – A cross-sectional study was
conducted in 2019 at four major haemophilia treatment
centres in Kuching, Sibu, Bintulu and Miri Hospitals,
Sarawak. Demographic and clinical data were collected with
consents from patients.
Results and Discussion: Ninety-six haemophilia patients
were identified - 79(82.3%) haemophilia A(HA) and 17(17.7%)
haemophilia B(HB). Severe haemophilia patients were noted
in 45.6% (36/79) of HA and 64.7% (11/17) of HB. In all 44.3%
of the HA and 52.9% of the HB population had no identifiable
family history of haemophilia. Two-thirds of the patients with
severe HA were on prophylaxis [24/36 (66.7%)] and only onethird [4/11 (36.4%)] in severe HB. Inhibitors developed in 9/79
(11.4%) of the HA population [3/79 (3.8%) high responders].
The median inhibitor titre was not significantly different
between the different treatment groups – on demand versus
prophylaxis (1.0BU versus 2.0BU; z statistic -1.043, p-value
0.297, Mann-Whitney test). None of the patients developed
inhibitory alloantibodies to factor IX. Four HA patients (5.1%)
underwent immune tolerance induction where one case had
a successful outcome. Three severe HA patients received
emicizumab prophylaxis and showed remarkable reduction
in bleeding events with no thromboembolic events being
reported. One female moderate HA patient received
PEGylated recombinant anti-haemophilic factor. Eleven
patients underwent radiosynovectomy. One mild HB patient
succumbed to traumatic intracranial bleeding. Our data
reported a prevalence (per 100,000 males) of 5.40 cases for
all severities of HA, 2.46 cases for severe HA; 1.16 cases for
all severities of HB, and 0.75 cases for severe HB. The
overall incidence of HA and HB was 1 in 11,500 and 1 in
46,000, respectively.
Conclusion: This study outlines the Sarawakian haemophilia
landscape and offers objective standards for forward
planning. Shared responsibilities among all parties are of
utmost importance to improve the care of our haemophilia
population.
