RESUMEN
Obscure gastrointestinal bleeding is defined as recurrent or persistent gastrointestinal bleeding in the setting of normal upper and lower endoscopies. There are reported use of numerous pharmacological agents to halt the bleeding, including oestrogen. We report a case of middle age gentleman with multiple comorbidities, presented with life threatening gastrointestinal bleeding. He underwent bidirectional endoscopies and mesenteric angiogram, but failed to localise the bleeding. Red blood cell scintigraphy showed numerous bleeding points in small and large bowels. A 5-day oral high dose oestrogen was prescribed in view of difficulty to manage the bleeding, in which the hemostasis was ultimately achieved.

BACKGROUND AND AIM: Variations in the Chicago 3.0 normative metrics may exist with different postures and with different provocative swallow materials in a healthy Asian population. METHOD: Eligible healthy Malay volunteers were invited to undergo the high-resolution esophageal manometry (inSIGHT Ultima, Diversatek Healthcare, Milwaukee, WI, USA). In recumbent and standing positions, test swallows were performed using liquid, viscous, and solid materials. Metrics including integrated relaxation pressure 4 s (IRP-4 s, mmHg), distal contractile integral (DCI, mmHg s cm), distal latency (DL, s), and peristaltic break (PB, cm) were reported in median and 95th percentile. RESULTS: Fifty of 57 screened participants were recruited, and 586 saline, 265 viscous, and 261 solid swallows were analyzed. Per-patient wise, in the recumbent position, 95th percentile for IRP-4 s, DCI, DL, and PB were 16.5 mmHg, 2431 mmHg s cm, 8.5 s, and 7.2 cm, respectively. We observed that with each posture, the use of viscous swallows led to changes in DL, but the use of solid swallows led to more changes in the metrics including DCI and length of PB. Compared with a recumbent posture, anupright posture led to lower IRP-4 s and DCI values. Both per-patient analysis and per-swallow analyses yielded almost similar results when comparing the different postures and types of swallows. No major motility disorders were observed in this cohort of asymptomatic population. However, more motility disorders were reported in the upright position. CONCLUSIONS: Variations in metrics can be observed in different postures and with different provocative swallow materials in a healthy population. The normative Chicago 3.0 metrics are also determined for the Malay population.

Gastric metastasis from breast carcinoma is uncommon and rarely encountered in our daily practice. We report a case of late gastric metastasis from previous infiltrating lobular carcinoma of the breast. The patient had extended disease-free interval of 22 years prior to metastasis. Gastroscopy and fluoroscopy showed changes appearing like linitis plastica of the body of the stomach. Computed tomography of the thorax and abdomen demonstrated pulmonary metastasis and mediastinal lymphadenopathy. Biopsy of the mediastinal lymph node and stomach lesion confirmed metastatic adenocarcinoma from breast carcinoma based on immunohistochemistry staining. Immunohistochemistry staining of both specimens revealed strong positivity for cytokeratin 7 and negative for cytokeratin 20.

Dysbiosis of the gut microbiome has been associated with the pathogenesis of colorectal cancer (CRC). We profiled the microbiome of gut mucosal tissues from 18 CRC patients and 18 non-CRC controls of the UKM Medical Centre (UKMMC), Kuala Lumpur, Malaysia. The results were then validated using a species-specific quantitative PCR in 40 CRC and 20 non-CRC tissues samples from the UMBI-UKMMC Biobank. Parvimonas micra, Fusobacterium nucleatum, Peptostreptococcus stomatis and Akkermansia muciniphila were found to be over-represented in our CRC patients compared to non-CRC controls. These four bacteria markers distinguished CRC from controls (AUROC = 0.925) in our validation cohort. We identified bacteria species significantly associated (cut-off value of > 5 fold abundance) with various CRC demographics such as ethnicity, gender and CRC staging; however, due to small sample size of the discovery cohort, these results could not be further verified in our validation cohort. In summary, Parvimonas micra, Fusobacterium nucleatum, Peptostreptococcus stomatis and Akkermansia muciniphila were enriched in our local CRC patients. Nevertheless, the roles of these bacteria in CRC initiation and progression remains to be investigated.

BACKGROUND The esophagus can be affected by a variety of disorders that may be primary or secondary to another pathologic process, but the resulting symptoms are usually not pathognomonic for a specific problem, making diagnosis and further management somewhat challenging. High resolution impedance manometry (HRiM) has established itself as a valuable tool in evaluating esophageal motility disorder. HRiM is superior in comparison with conventional water perfused manometric recordings in delineating and tracking the movement of functionally defined contractile elements of the esophagus and its sphincters, and in distinguishing the luminal pressurization of spastic esophageal contraction from a trapped bolus. Making these distinctions can help to identify achalasia, distal esophageal spasm, functional obstruction, and subtypes according to the latest Chicago Classification of Esophageal Motility Disorders version 3.0. CASE REPORT We report a case series of 4 patients that presented with dysphagia; and with the ancillary help of the HRiM, we are able to diagnose esophageal motility disorder and evaluate its pathogenetic mechanism. This approach aids in tailoring each management individually and avoiding disastrous mismanagement. CONCLUSIONS From the series of case reports, we believe that HRiM has an important role to play in deciding appropriate management for patients presenting with esophageal motility disorders, and HRiM should be performed before deciding on management.

Background and Aims: Patients with inflammatory bowel disease (IBD) are subjected to a large amount of ionizing radiation during the course of their illness. This may increase their risk of malignancy to a greater level than that due to the disease itself. In Caucasian patients with Crohn's disease, this has been well documented and recommendations are in place to avoid high radiation imaging protocols. However, there are limited data available on radiation exposure in Asian IBD patients.We therefore sought to identify total radiation exposure and any differences between ethnically diverse ulcerative colitis (UC) and Crohn's disease (CD) patients at our centre along with determining factors that may contribute to any variation. Methods: The cumulative effective dose (CED) was calculated retrospectively from 2000 to 2014 using data from our online radiology database and patients' medical records. Total CED in the IBD population was measured. High exposure was defined as a radiation dose of greater than 0.2mSv (equivalent to slightly less than ½ a year of background radiation). Results: A total of 112 cases of IBD (36 CD and 76 UC) were reviewed. Our CD patients were diagnosed at an earlier age than our UC cases (mean age 26.1 vs 45.7). The total CED in our IBD population was 8.53 (95% CI: 4.53-12.52). Patients with CD were exposed to significantly higher radiation compared to those with UC. The mean CED was 18.6 (7.30-29.87) and 3.65 (1.74-5.56, p=0.01) for CD and UC patients respectively. 2 patients were diagnosed as having a malignancy during follow up with respective CED values of 1.76mSv and 10mSv. Conclusions: CD patients, particularly those with complicated disease, received a higher frequency of diagnostic imaging over a shorter period when compared to UC patients. Usage of low radiation imaging protocols should be encouraged in IBD patients to reduce their risk of consequent malignancy.
RESUMEN
An epidermal cyst is the most common type of cyst to occur in subcutaneous tissue. When its size is greater than 5 cm, it is recognised as a giant epidermal cyst. A subcutaneous giant epidermal cyst with intramuscular extension is extremely rare. The authors report a case of a 74-year-old man who presented with a painless, slow-growing left gluteal mass of 6-month duration. Examination revealed a large left gluteal mass that was fixed to the underlying structures. A small epidermal cyst with visible punctum was noted at the medial aspect of the mass. MRI demonstrated a large, lobulated left gluteal lesion measuring 20 cm×16 cm×10 cm. The lesion was partly within the gluteal maximus muscle and partly within the subcutaneous tissue. MRI and ultrasound features of the lesion were consistent with a giant epidermal cyst with intramuscular extension. The lesion was excised and histology confirmed the diagnosis.

Spondyloarthropathy (SpA) is a group of inflammatory conditions that include spondylitis, sacroiliitis, asymmetrical peripheral arthritis and enthesitis. This condition is known as juvenile SpA when the diagnosis is made in patients up to 16 years of age. Enthesitis is a highly specific feature that occurs more often in juvenile SpA than in the adult form. In contrast to adult onset SpA, the initial manifestation of juvenile SpA rarely presents as inflammatory back pain. Peripheral arthritis is the more common presenting feature. We report a case of a 12-year-old boy who presented with a 1-year history of progressive low back pain, gluteal pain and thigh pain. There were no clinical symptoms of arthropathy of the distal extremities. MRI of the whole spine was performed twice, which, unfortunately, was unyielding. Finally, MRI of the sacroiliac joints revealed asymmetric sacroiliitis as well as enthesitis of the hips and pelvis. Further laboratory data showed negative rheumatoid factor and positive human leucocyte antigen (HLA) B27. A diagnosis of juvenile SpA with sacroiliitis and enthesitis was made. The imaging characteristics of juvenile SpA are highlighted.

Multiple myeloma (MM) is characterized by progressive proliferation of malignant plasma cells, usually initiating in the bone marrow. MM can affect any organ; a total of 7 - 18% of patients with MM demonstrate extramedullary involvement at diagnosis. Non-secretory multiple myeloma (NSMM) is a rare variant that accounts for 1 - 5% of all cases of multiple myeloma. The disease is characterized by the absence of monoclonal gammopathy in serum and urine electrophoresis. Our case report highlights the diagnostic challenge of a case of NSMM with extensive extramedullary involvement in a young female patient who initially presented with right shoulder pain and bilateral breasts lumps. Skeletal survey showed multiple lytic bony lesions. The initial diagnosis was primary breast carcinoma with osseous metastases. No monoclonal gammopathy was found in the serum or urine electrophoresis. Bone marrow and breast biopsies revealed marked plasmacytosis. The diagnosis was delayed for a month in view of the lack of clinical suspicion of multiple myeloma in a young patient and scant biochemical expression of non-secretory type of multiple myeloma.
RESUMEN
Midgut malrotation commonly presents in the neonatal period, and rarely manifests its symptoms in adulthood with an estimated incidence of 0.2-0.5%. Nevertheless, the symptoms are non-specific with no strong pointers towards the clinical diagnosis. Consequently, the diagnosis is usually disclosed with imaging or surgery. We report a case of small bowel obstruction secondary to a congenital peritoneal band with underlying midgut malrotation in a 48-year-old man.

INTRODUCTION: Camurati-Engelmann disease (CED) is a rare autosomal dominant disease with various phenotypic expressions. The symptoms usually develop during childhood. The hallmark of the disease is bilateral symmetric diaphyseal hyperostosis of the long bones with progressive involvement of the metaphysis. The epiphysis is strictly spared. The common clinical symptoms are pain of the extremities, muscle wasting, waddling gait, and lethargy. CED is rarely seen in conjunction with hypogonadism. CED-associated hypothyroidism has not been reported yet. Clinical assessment and skeletal survey are important to make the diagnosis. CASE PRESENTATION: Hereby we reported a case of CED with concomitant hypogonadism and hypothyroidism. Serial plain radiographs of the patient showed classic and progressive diaphyseal cortical hyperostosis of the long bone. CONCLUSIONS: Hyperostosis of the skull was observed in the present case. The characteristic osseous changes of CED were highlighted and the differential diagnoses were discussed.
RESUMEN
Pseudotumours are rare, occurring in 1-2% of severe haemophiliacs. Osseous locations are far less frequent than soft tissue location. We report a case of a 43-year-old man with haemophilia A, who presented with a gradually enlarging left thigh mass for 8 months. There were no constitutional symptoms. Plain radiograph showed an expansile lytic lesion with 'soap-bubble' appearance arising from the left femur diaphysis. On MRI, it appeared as a non-enhancing, multilobulated lesion expanding the medullary and subperiosteal spaces. The mass exhibited concentric ring sign with heterogeneous intermediate signal intensity in the core lesion, reflective of chronic haematoma with blood degradation products of different stages. A diagnosis of haemophilic pseudotumour was made. Hypercalcaemia, however, raised a diagnostic dilemma as bone malignancy needed to be considered. An open excisional biopsy and subsequent amputation confirmed the diagnosis of osseous haemophilic pseudotumour. Nuclear medicine study later revealed a concurrent parathyroid adenoma.

Pulmonary tuberculosis (PTB) is a common infectious disease worldwide. However, mediastinal tuberculous lymphadenitis complicated by oesophageal involvement and oesophago-respiratory fistula is now uncommon due to improved anti-tuberculous regimes and better general awareness. The overall incidence of acquired oesophago-respiratory fistula due to infection is low, and therefore, the lesion is not often a frontrunner in differential diagnosis. Still, tuberculous oesophago-respiratory fistulae can potentially occur in patients with retroviral disease, as they tend to have atypical and more virulent manifestations. In this study, we report the case of multiple oesophago-respiratory fistulae in a patient with PTB and retroviral disease, and highlight the computed tomography features of these lesions as an atypical presentation of PTB in retroviral disease. Clinicians should suspect oesophago-respiratory fistulae if patients present with Ono's sign, and remain particularly vigilant for patients with underlying PTB and retroviral disease, as early diagnosis and treatment could help to reduce mortality.

Percutaneous Endoscopic Gastrostomy (PEG) tubes were often offered to patients requiring long term enteral feeding. Even though the procedure is relatively safe, it is associated with various complications such as peritonitis or even death. 1 We presented a case of a 54-year-old gentleman with underlying ischemic stroke and pus discharges from a recently inserted PEG tube. Computed Topography (CT) scan confirmed abdominal wall necrotising fasciitis complicated with hyperosmolar hyperglycaemia state (HHS) and later succumbed after 48 hours of admission. Our case illustrated the rare complication related to the insertion of PEG tube; abdominal wall necrotising fasciitis that was associated with mortality.

Hashimoto encephalopathy (HE) is a poorly recognised steroid-responsive encephalopathy, with prominent neuropsychiatric features. Diagnosis is often difficult due to its heterogeneous clinical presentation, especially since the thyroid status or anti-thyroid antibody titres may not be related to the disease state. Here, the case of a 23-year-old Malay woman with Graves disease who presented with progressive encephalopathy diagnosed as HE is presented. She responded dramatically to high dose intravenous and then oral corticosteroid. A month after the initiation of treatment, she regained full independency.
