We report an18-year-old girl with a four-year history of a slow-growing labial mass with a sudden increase in size in the last year. Examination revealed a large fl eshy 20 cm perineal mass centering on the left labia majora and attached to it by a 1cm pedicle. It was associated with pain, ulceration and discharge. The lesion was excised via diathermy at the base of the stalk. The excised specimen weighed 1.112kg and measured 20.5 x 17 x 5cm. The lesion showed a solid, soft whitish, cut surface. Histology revealed a hypocellular tumour with focally oedematous fi brous stroma in which were scattered large and small blood vessels, mast cells and other chronic infl ammatory cells. True myxoid matrix was not observed. The stromal cells had a spindle to stellate morphology. There was no signifi cant cytological atypia, mitotic activity or necrosis. The tumour cells were negative for SMA, desmin, CD34, S100 protein, EMA and PR. The diagnosis was clinically and histologically challenging because various vulvovaginal soft tissue tumours often have overlapping clinicopathological features. However, based on strict histological criteria and the absence of worrisome cytological features, a diagnosis of fi broepithelial stromal polyp was rendered despite the unusual size. A review of the literature shows that whilst vulvovaginal fi broepithelial stromal polyps are well described, giant variants are rare. Awareness of the extraordinary size that can be attained by such polyps can fascilitate swift clinical and histological diagnosis.

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

Daptomycin, a lipopeptide antibiotic with similar action as vancomycin, is used to treat complicated skin and soft tissue infections caused by resistant Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus, penicillin-resistant streptococci, and vancomycin-resistant enterococci. Acute generalized exanthematous pustulosis (AGEP), characterized by acute onset of numerous sterile, nonfollicular pinhead sized pustules, is common secondary to drugs, in particular, antibiotics. We present the first case of AGEP following the use of daptomycin.

Nanostructured materials are gaining new impetus owing to the advancements in material fabrication techniques and their unique properties (their nanosize, high surface area-to-volume ratio, and high porosity). Such nanostructured materials mimic the subtleties of extracellular matrix (ECM) proteins, creating artifi cial microenvironments which resemble the native niches in the body. On the other hand, the isolation of mesenchymal stem cells (MSCs) from various tissue sources has resulted in the interest to study the multiple differentiation lineages for various therapeutic treatments. In this review, our focus is tailored towards the potential of biomimetic nanostructured materials as osteoinductive scaffolds for bone regeneration to differentiate MSCs towards osteoblastic cell types without the presence of soluble factors. In addition to mimicking the nanostructure of native bone, the supplement of collagen and hydroxyapatite which mimic the main components of the ECM also brings signifi cant advantages to these materials.

Background and Objectives: To assess whether the audiological and clinical outcomes of type 0 tympanoplasty (T0) performed using cartilage were comparable with those of ossiculoplasty in patients who underwent canal wall down mastoidectomy (CWDM). Subjects and Methods: This study included patients who had chronic otitis media with cholesteatoma and underwent CWDM with ossiculoplasty involving partial ossicular replacement prosthesis (PORP), total ossicular replacement prosthesis (TORP), or T0. Anatomical success rates and hearing outcomes were analyzed. Results: Seventy-two patients were included in this study; 29 of them underwent CWDM with T0, 27 underwent CWDM with PORP, while 16 underwent CWDM with TORP. The difference in mean improvement in the air-bone gap (ABG) between the groups was not significant. The differences in the rates of ABG closure to ≤10 dB HL (p=0.030) and ≤20 dB HL (p=0.029) were significant. There were significant differences in improvements in the ABG at 3 kHz among the PORP, TORP, and T0 groups. Conclusions The audiological outcomes of CWDM with ossiculoplasty seemed to be better than those of CWDM with T0 with no significant difference in the incidence of complications following ossiculoplasty and T0.

IntroductionManagement of leprosy in pregnancy is challenging. Here we aim to describe the clinical characteristicsand the management of leprosy in pregnancy.MethodsThis is a retrospective study on pregnant women with leprosy managed in the Department ofDermatology in Hospital Kuala Lumpur, Hospital Pulau Pinang, Hospital Sultanah Bahiyah andHospital Queen Elizabeth between 1994 and 2015.ResultsThere were ten patients with 12 pregnancies with a median age of 27.5 years (range: 16-33). Fivewere foreigners. There were four cases of lepromatous leprosy, two cases of borderline lepromatous,two cases borderline tuberculoid leprosy and one case each for tuberculoid and mid borderline leprosy.Seven pregnancies (58%) were documented to have reactions. Four reversal reactions (33%), threeerythema nodusom leprosum (25%) and two Lucio’s phenomenon (17%) were documented. Bothpatients with Lucio’s phenomenon had undiagnosed leprosy and presented with preterm labour,anemia, oligohydramnios and intrauterine growth restriction. Mortality was recorded in one patientdue to dapsone induced hypersensitivity syndrome complicated with septicaemia. All patients wereprescribed multidrug therapy but in three pregnancies, the patients chose to defer the treatment. Therewas a spontaneous miscarriage at second trimester and a case of early neonatal death. The neonatalcomplications recorded for the 10 live deliveries were low birth weight, jaundice and clofazimineinducedhyperpigmentation.ConclusionThe majority of our patients with leprosy had complications throughout the pregnancies. Earlydetection and prompt treatment can prevent unfavorable fetal outcome & threatened maternal health.

INTRODUCTIONElectrocardiographic (ECG) criteria for left ventricular hypertrophy (LVH), such as the Cornell and Sokolow-Lyon voltage criteria were derived from Western populations. However, their utility and accuracy for diagnosing echocardiographic LVH in Asian populations is unclear. The objective of this study was to assess the accuracy of ECG criteria for LVH in Asians and to determine if alternative gender-specific ECG cut-offs may improve its diagnostic accuracy.

MATERIALS AND METHODSECG and echocardiographic assessments were performed on 668 community-dwelling Asian adults (50.9% women; 57 ± 10 years) in Singapore. The accuracy of ECG voltage criteria was compared to echocardiographic LVH criteria based on the American Society of Echocardiography guidelines, and Asian ethnicity and gender-specific partition values.

RESULTSEchocardiographic LVH was present in 93 (13.6%) adults. Cornell criteria had low sensitivity (5.5%) and high specificity (98.9%) for diagnosing LVH. Modified gender specific cut-offs (18 mm in women, 22 mm in men) improved sensitivity (8.8% to 17.5%, 0% to 14.7%, respectively) whilst preserving specificity (98.2% to 94.2%, 100% to 95.8%). Similarly, Sokolow-Lyon criteria had poor sensitivity (7.7%) and high specificity (96.1%) for diagnosing LVH. Lowering the cut-off value from 35 mm to 31 mm improved the sensitivity in women from 3.5% to 14% while preserving specificity at 94.2%. A cut-off of 36 mm was optimal in men (sensitivity of 14.7%, specificity of 95.5%).

CONCLUSIONCurrent ECG criteria for LVH derived in Western cohorts have limited sensitivity in Asian populations. Our data suggests that ethnicity- and gender-specific ECG criteria may be needed.

Systemic infections due to Fusobacterium may originate in the tonsillar/internal jugular veins or from the abdomen. We encountered a patient who presented with bacteremia, fulminant septic shock, and extensive soft tissue pyogenic infection due to Fusobacterium necrophorum.In addition, there was widespread metastatic colon cancer with the unique finding of premortem co-localization of F. necrophorum and cancer cells at a site distant from the colon. We reviewed the literature of the association of F. necrophorum and colon cancer, and discuss the evidence of how each of these 2 distinct entities may mutually augment the development or progression of the other.
