Fulltext More than meets the naked eye: an unusual psoriatic arthritis mimicry and the important role of dermoscopic examination

Anne LJ, Rahim MJC, Ghazali WSW, Ahmed WAW, Isa SAM

BMC Rheumatol, 2021 Apr 12;5(1):10.
PMID: 33840385 DOI: 10.1186/s41927-021-00182-7

BACKGROUND: Psoriatic arthritis (PsA) can manifest in various forms. This includes mimicry of other diseases. We describe an unusual mimicry of PsA.
CASE PRESENTATION: We report a case of a middle-aged lady who presented with severe pain and morning stiffness over the small joints of the left hand for 3 months and painless deformity of the affected joints 1 year before. She was under treatment for pruritic rash over her ankles and knees for the past 1 year as well. Physical examination revealed a fixed flexion deformity, swelling and tenderness of the left ring and little fingers' distal interphalangeal (DIP) joints. Left hand radiograph showed sclerotic joint margin, narrowed joint space and marginal osteophytes of the affected DIP joints. Dermoscopic examination showed red- violaceous, flat-topped papules and plaques with minimal scales on both ankles; hyperpigmented scaly plaques over both knees and vertical fingernail ridges. Serum autoimmune screening and inflammatory markers were unremarkable. Left ankle skin biopsy showed features consistent of psoriasis. PsA was diagnosed. Weekly titrated oral methotrexate and topical steroid were started. The patient showed significant improvement after 1 month of treatment.
CONCLUSION: PsA is a great mimicker. Dermoscopy is an accessible and valuable tool to assess skin lesions in greater detail. Clinicians should be aware of coexisting diseases or misdiagnosis when patients do not respond to treatment.

Fulltext Glycogenic hepatopathy in children with poorly controlled type 1 diabetes mellitus

Abu NA, Lim CB, Nor NSM

Clin Pediatr Endocrinol, 2021;30(2):93-97.
PMID: 33867669 DOI: 10.1297/cpe.30.93

Mauriac syndrome is a rare and underdiagnosed complication of type 1 diabetes mellitus (T1DM). It is characterized by growth retardation, delayed puberty, Cushingoid features, hepatomegaly, and increased transaminase levels. The term glycogenic hepatopathy has been used to describe patients with poorly controlled T1DM and glycogen overload in the hepatocytes but without all the features of Mauriac syndrome. Although rare, glycogenic hepatopathy is reported to be the main cause of hepatomegaly in young patients with T1DM. We report two cases of glycogenic hepatopathy in children with poorly controlled T1DM. Both children had hepatomegaly, elevated liver enzyme levels, and elevated lactate levels. A liver biopsy confirmed the diagnosis of glycogenic hepatopathy in both patients. In conclusion, hepatomegaly with elevated liver enzymes, negative infective and metabolic screenings and persistently elevated plasma lactate levels should raise the suspicion of glycogenic hepatopathy in poorly controlled T1DM. Early diagnosis and improvement in glycemic control are the mainstays of treatment, which can prevent long-term complications.

Fulltext Diamond-Blackfan anemia with mutation in RPS19: A case report and an overview of published pieces of literature

Jahan D, Al Hasan MM, Haque M

J Pharm Bioallied Sci, 2020 04 10;12(2):163-170.
PMID: 32742115 DOI: 10.4103/jpbs.JPBS_234_19

Introduction: Diamond-Blackfan anemia (DBA), one of a rare group of inherited bone marrow failure syndromes, is characterized by red cell failure, the presence of congenital anomalies, and cancer predisposition. It can be caused by mutations in the RPS19 gene (25% of the cases).
Methods: This case report describes a 10-month-old boy who presented with 2 months' history of gradually increasing weakness and pallor.
Results: The patient was diagnosed as a case of DBA based on peripheral blood finding, bone marrow aspiration with trephine biopsy reports, and genetic mutation analysis of the RPS19 gene. His father refused hematopoietic stem cell transplantation for financial constraints. Patient received prednisolone therapy with oral folic acid and iron supplements.
Conclusion: Hemoglobin raised from 6.7 to 9.8g/dL after 1 month of therapeutic intervention.

Fulltext Use of simple scoring systems for a public health approach in the management of non-alcoholic fatty liver disease patients

Zain SM, Tan HL, Mohamed Z, Chan WK, Mahadeva S, Basu RC, et al.

JGH Open, 2020 Dec;4(6):1155-1161.
PMID: 33319051 DOI: 10.1002/jgh3.12414

Background and Aim: Advanced fibrosis is the most important predictor of liver-related mortality in non-alcoholic fatty liver disease (NAFLD). The aim of this study was to compare the diagnostic performance of noninvasive scoring systems in identifying advanced fibrosis in a Malaysian NAFLD cohort and propose a simplified strategy for the management of NAFLD in a primary care setting.
Methods: We enrolled and reviewed 122 biopsy-proven NAFLD patients. Advanced fibrosis was defined as fibrosis stages 3-4. Noninvasive assessments included aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio, AST-to-platelet ratio index (APRI), AST/ALT ratio, diabetes (BARD) score, fibrosis-4 (FIB-4) score, and NAFLD fibrosis score.
Results: FIB-4 score had the highest area under the receiver operating characteristic curve (AUROC) and negative predictive value (NPV) of 0.86 and 94.3%, respectively, for the diagnosis of advanced fibrosis. FIB-4 score

Introduction: Rectal schwannoma is a rare gastrointestinal mesenchymal tumour with only a few numbers of cases has been reported. It is predominant in the stomach and small bowel, but uncommon in the colon and rectum. Case description: A 74-year-old man presented with features masquerading as low rectal malignancy with a malignant looking pedunculated polyp measuring 10 x 8 cm on colonoscopy. Punch biopsy revealed a diagnosis of benign tumour of schwannoma. After failure of multiple attempts of endoscopic resection, a decision of transanal excision was made. The histopathological assessment was consistent with the preoperative diagnosis and supported by immu-nohistochemistry of S-100 protein. His postoperative recovery was uneventful as he was discharged on the following day. There is no evidence of tumour recurrence on follow up. Conclusion: A huge tumour of the rectum is not always malignant. However, patient with features of low rectal tumour warrants an immediate referral to the surgical team as this non-communicable disease is a public health concern. Preoperative diagnosis is paramount for a necessary surgical intervention.

Diagnosis and management of fatty liver

Tan PO, Mustaffa N, Tan SS, Lee YY

J R Coll Physicians Edinb, 2020 Sep;50(3):256-261.
PMID: 32936098 DOI: 10.4997/JRCPE.2020.308

Globally, the prevalence of non-alcoholic fatty liver disease (NAFLD) is increasing rapidly and constitutes a significant healthcare burden due to associated complications including hepatic (cirrhosis and hepatocellular cancer) and non-hepatic (cardiovascular deaths) disorders. It is closely linked to insulin resistance and metabolic syndrome but moderate alcohol consumption frequently coexists. Recently, genetic polymorphisms were implicated in the development of non-obese NAFLD. Apart from liver biopsy, in order to assess for steatosis, fibrosis and non-alcoholic steatohepatitis (NASH), advances in non-invasive serum tests and elastography have provided similarly accurate, more accessible and safer alternatives for risk stratification. As for treatment in 2020, weight loss and lifestyle modification remain the central strategy. Unfortunately, no pharmacological agents have been approved thus far, but there are a number of potential therapies in the pipeline for fibrosis and NASH. Treatment of underlying metabolic disorders is important. While the term NAFLD was coined in the 1980s, more recent understanding may support a change in nomenclature highlighting its strong metabolic roots.

In-vivo Barrett's esophagus digital pathology stage classification through feature enhancement of confocal laser endomicroscopy

Ghatwary N, Ahmed A, Grisan E, Jalab H, Bidaut L, Ye X

J Med Imaging (Bellingham), 2019 Jan;6(1):014502.
PMID: 30840732 DOI: 10.1117/1.JMI.6.1.014502

Barrett's esophagus (BE) is a premalignant condition that has an increased risk to turn into esophageal adenocarcinoma. Classification and staging of the different changes (BE in particular) in the esophageal mucosa are challenging since they have a very similar appearance. Confocal laser endomicroscopy (CLE) is one of the newest endoscopy tools that is commonly used to identify the pathology type of the suspected area of the esophageal mucosa. However, it requires a well-trained physician to classify the image obtained from CLE. An automatic stage classification of esophageal mucosa is presented. The proposed model enhances the internal features of CLE images using an image filter that combines fractional integration with differentiation. Various features are then extracted on a multiscale level, to classify the mucosal tissue into one of its four types: normal squamous (NS), gastric metaplasia (GM), intestinal metaplasia (IM or BE), and neoplasia. These sets of features are used to train two conventional classifiers: support vector machine (SVM) and random forest. The proposed method was evaluated on a dataset of 96 patients with 557 images of different histopathology types. The SVM classifier achieved the best performance with 96.05% accuracy based on a leave-one-patient-out cross-validation. Additionally, the dataset was divided into 60% training and 40% testing; the model achieved an accuracy of 93.72% for the testing data using the SVM. The presented model showed superior performance when compared with four state-of-the-art methods. Accurate classification is essential for the intestinal metaplasia grade, which most likely develops into esophageal cancer. Not only does our method come to the aid of physicians for more accurate diagnosis by acting as a second opinion, but it also acts as a training method for junior physicians who need practice in using CLE. Consequently, this work contributes to an automatic classification that facilitates early intervention and decreases samples of required biopsy.

Fulltext Development of folliculitis in a patient with recalcitrant pustular psoriasis following acitretin treatment: A case report

Nur Ashikin Ahmad, Tarita Taib, Meera Kuppusamy

Journal of Clinical and Health Sciences, 2017;2:48-51.

Oral retinoids are among the drugs of choice for pustular psoriasis. Therapy with retinoids, including acitretin, is potent teratogens with other common side effects such as mucocutaneous involvement. Mucocutaneous side effects including dry lips (cheilitis), skin peeling, hair loss (alopecia), dry skin, or rhinitis are dose-related, with cheilitis occurring in more than 75% of patients receiving the highest doses of acitretin (75 mg/day). We report on a 37-year-old woman who developed folliculitis with acitretin which is a rare cutaneous side effect. She presented with eruptions pruritic papules with follicular pattern on anterior thigh and forearms after almost 1 year of treatment with acitretin (50mg OD) for pustular psoriasis. The skin lesion was treated successfully with skin dressing and antibiotic treatment and skin biopsy is suggestive of folliculitis. Several treatments for pustular psoriasis including topical steroids, methotrexate and oral prednisolone were ineffective or not tolerated. Treatment with acitretin which are 50mg OD provided partial resolution of skin lesions. The case is hereby reported because of its rarity and folliculitis must be considered in the differential diagnosis of a popular eruption, especially in patients with high dose acitretin.

Metastatic leiomyosarcoma of the thyroid: A rare entity

Che Jalil NA, Rama Chandran P, Samsudin AHZ, Yahya MM, Wan Abdul Rahman WF

Malays J Pathol, 2021 Apr;43(1):69-73.
PMID: 33903308

Cancer metastasis to the thyroid gland from non-thyroid sites is a rare presentation in clinical practice. The most frequent primary cancers that metastasise to the thyroid are renal cell carcinoma, followed by colorectal, lung and breast. We report a case of a 64-year-old Malay lady who presented with anterior neck swelling 4 years after an initial diagnosis of uterine leiomyosarcoma. She had undergone a hysterectomy procedure four years ago. Fine needle aspiration cytology of the thyroid mass suggested undifferentiated thyroid carcinoma. After multi-disciplinary discussion, the patient underwent thyroidectomy and the final histopathological diagnosis was metastatic leiomyosarcoma of the thyroid. The diagnosis was aided by an immunohistochemistry panel of positive myogenic markers, negative epithelial markers as well as the previous medical history of uterine leiomyosarcoma. Metastatic leiomyosarcoma of the thyroid may mimic primary undifferentiated (anaplastic) thyroid carcinoma (UTC) with a sarcomatoid pattern, medullary thyroid carcinoma (MTC) with spindle cells morphology and spindle cell tumour with thymus-like differentiation (SETTLE). Hence, a multidisciplinary approach must be practised by pathologists, surgeons and radiologists to consider metastatic lesions of the thyroid gland, especially when a previous history of cancer exists or is suspected.

Cutaneous involvement of multiple myeloma

Mohtarrudin N, Bakrin IH, Ambrose D, Jo Lyn L, Mukhtar NSA

Malays J Pathol, 2021 Apr;43(1):75-79.
PMID: 33903309

Cutaneous multiple myeloma (MM) is a rare disease. It can be primary or secondary in origin. The secondary type is further classified into specific and nonspecific types. The specific type is uncommon and is known as a secondary cutaneous plasmacytoma. We report a case of secondary cutaneous plasmacytoma in a 58-year-old man who had a history of plasma cell tumour of the lung and multiple myeloma. He achieved complete remission after the completion of chemotherapy and autologous stem cell transplant (ASCT). However, five months later, he developed multiple erythematous nodules on the whole body. Skin biopsy revealed diffuse neoplastic cells infiltrate in the reticular dermis with sparing of the upper papillary dermis and epidermis. The neoplastic cells were monotonous and homogenous with variable degrees of cytological atypia. Occasional cells showed distinctive plasma cell features. Plasma cell lineage was confirmed with CD138. The cells were immunoreactive to Kappa. Ki-67 was greater than 90%. They were non-immunoreactive to CD45, CD3, CD20, CD79 alpha and CK AE1/AE3. The findings were consistent with secondary cutaneous plasmacytoma. Our case illustrates that MM may present with nonspecific dermatological manifestations. As specific cutaneous involvement of MM is very uncommon; a high degree of clinical suspicion, detailed medical history and histopathological examination are required to arrive at an early diagnosis.

Madhusudhan Krishnamoorthy, Zaleha Kamaludin, Hasnan Jaafar, Norhafiza Mat Lazim

Malaysian Journal of Medicine and Health Sciences, 2020;16(2):339-341.
MyJurnal

Nasopharyngeal carcinoma is a commonly encountered malignancy in endemic regions of the world namely South
East Asia, China and Hong Kong. In Malaysia, the ethnic Chinese population is particularly at risk due to genetic
susceptibilities and environmental exposure to carcinogenic agents. We herein report a case of nasopharyngeal carcinoma in a middle-aged man of Malay ethnicity who presented with nasal blockage and neck nodes. The biopsy of
the nasopharyngeal mass came back as papillary variant of nasopharyngeal carcinoma. The commonly reported histopathological types are the keratinizing and non-keratinizing types, and rarely the basaloid type. In this case report,
we aim to highlight one of the rare variants of the non-keratinizing nasopharyngeal carcinoma. When diagnosing the
non-keratinizing type, appreciation of the different morphological variants is crucial not only to help aid in procuring
an acurrate histopathologic diagnosis, but also to help in subsequent treatment plan.

Fulltext A Rare Case of Synovial Osteochondromatosis of the Elbow

Loh, Li Loong, Wong, Kai Ann, Zamzuri Zakaria@Mohamad

Borneo Journal of Medical Sciences, 2019;13(3):49-57.
MyJurnal

Synovial osteochondromatosis is an unusual, rare and benign tumour. This disease is characteristically monoarticular, most commonly found in knee joint, however it is rarely found in the elbow. A 49-year-old Indian man presented to hospital with a 6-month history of pain, swelling, intermittent locking, loss of range of motion of right elbow and a considerable size of elbow with no recollection of associated trauma. Plain radiographs of right elbow showed numerous radiopaque round and oval loose bodies within the right elbow joints. Computer Tomographic (CT) scan showed multiple bony mass within the right elbow joint. Arthroscopic synovectomy, debridement, excisional biopsy and loose body removal combined with miniarthrotomy of the right elbow was performed due to limited exposure for removal of larger loose bodies. Histopathological examination of the tissue sample is consistent with the diagnosis of synovial osteochondromatosis. The clinical and radiological evaluation at 6th month postoperatively showed marked reduction in the volume of the elbow, further improvement of elbow range of motion of this patient and the Mayo elbow performance score before surgery and at 6 months postoperative, with an increase from 50 to 80 points. Synovial osteochondromatosis of the joints is a rare condition. The signs and symptoms are not specific and may be suggestive of other pathology conditions. Arthroscopic synovectomy and removal of loose body is the standard operative procedure till today. However, combination of arthroscopy and miniarthrotomy in cases of large loose bodies may provide a good clinical and functional outcome.

Skeletal metastasis is a frequent complication of cancer resulting in significant morbidity as well as mortality. We highlight a case of a 73-year old gentleman with metastatic squamous cell carcinoma of the sternum. He denied dysphagia, shortness of breath, goitre, and presence of chronic non-healing ulcer. He was anaemic and carcinoembryonic antigen (CEA) was 18.7. Chest radiograph on lateral view showed a suspicious cortical irregularity. Computed tomography (CT) scan of thorax revealed an aggressive sternal lesion with soft tissue component. Ultrasound guided biopsy was performed and the biopsy was consistent with metastatic squamous cell carcinoma. Squamous cell carcinoma has a predilection to metastasize via haematogenous spread, but direct extension of tumour into the bone is not frequently seen. Finding the primary cause is utmost importance either via imaging modalities or invasive procedures. Isolated secondary lesion is extremely rare but unfortunate among defaulters. We discuss its diagnostic work-up and treatment options conserved to manage this condition.

PMID: 32843942

Atypical forms of herpes simplex virus (HSV) infections, which indicate severe impairment of cellular immunity can be challenging to diagnose. In this paper, we report the case of an atypical HSV infection presenting as chronic nonhealing wounds, which are the first sign of HIV, in a 50-year-old female patient. The lesions had emerged as two large, chronic, and painful ulcerations on the left buttock and labia major 8 months prior. The skin biopsy revealed multinucleated keratinocytes with ground glass nuclei and intranuclear Cowdry type A viral inclusions. A serologic test for HIV-1 was positive. Her CD4+ T-cell count was 42/mm3. Clinicians should be familiar with the dermatologic manifestations of HIV, as they are occasionally key to correctly suspecting an underlying HIV infection, allowing for early diagnosis and treatment.

Fulltext A Clinicopathologic Study of Seven Cases of Orbital Solitary Fibrous Tumours

Ting XW, Sothiraghagan S, W Md Kasim WM, Muhammed J

Cureus, 2020 May 24;12(5):e8259.
PMID: 32596077 DOI: 10.7759/cureus.8259

Objective To describe the patient demographics, clinical findings, investigations, surgical outcomes, and histopathological findings of seven cases of orbital solitary fibrous tumours. Method This was a retrospective review of seven cases of orbital solitary fibrous tumour, which were followed up in Hospital Serdang, a national oculoplastic centre, from years 2008-2017. Results This study included seven patients with ages between 21 and 35 years old; two were males and five were females. All seven patients presented with painless chronic unilateral proptosis. Radiological imaging of the orbit showed a localized contrast enhancing intraorbital mass. All patients underwent orbitotomy and excisional biopsy. Intraoperative findings showed a well-encapsulated and vascularized mass. Histological findings of spindle-shaped cells were noted. All cases had positive staining for cluster of differentiation (CD) 34, five were positive for CD 99, four were positive for B-cell lymphoma (BCL-2), and five patients had positive staining for S-100. Three of the patients did not have clear margins during the primary operation and subsequently had a recurrence within two years. Conclusion A solitary fibrous tumour is a rare mesenchymal tumour with a pleural origin. The orbit is the most common extrapleural site of the tumour and they are usually benign. Immunohistochemistry is important to differentiate it from other, more aggressive forms of orbital tumours. Regular follow-up is important to monitor for recurrence.

Bone and joint tuberculosis is a serious medical problem; tuberculosis of sternoclavicular joint is rare. We present a case of a healthy 37-year old man with sternoclavicular joint tuberculosis. The subject presented with a three weeks history of left sternoclavicular joint painless swelling without fever or weight loss. He had no previous history of pulmonary tuberculosis. Laboratory testing revealed erythrocyte sedimentation rate of 70 mm/hour, C-reactive protein of 30 mg/liter and a normal leucocyte count. Biopsy of the lesion showed caseous necrosis and pus culture revealed Mycobacterium tuberculosis. He was treated with joint debridement and anti-tuberculous medications. Tuberculosis resolved completely but post-infection patients had residual joint arthritis. Tuberculosis may infect unusual joints such as the sternoclavicular joint.

PMID: 33505755 DOI: 10.1155/2021/6693031

Lymphocytic interstitial pneumonia (LIP) is a rare condition, commonly associated with Sjogren's syndrome (SS). We report a 53-year-old woman with an incidental finding of an abnormal chest radiograph. LIP was diagnosed based on high-resolution computed tomography and lung biopsy, but treatment was not initiated. Six years later, she developed cough and dyspnoea, associated with dry eyes, dry mouth, and arthralgia. While being investigated for the respiratory symptoms, she developed cutaneous vasculitis and was treated with 1 mg/kg prednisolone, which resulted in the improvement of her respiratory symptoms. Physical examination revealed fine bibasal crepitations, active vasculitic skin lesions, and a positive Schirmer's test. Investigations revealed a restrictive pattern in the pulmonary function test, stable LIP pattern in HRCT, and positive anti-Ro antibodies. She was treated with prednisolone and azathioprine for 18 months, and within this time, she was hospitalised for flare of LIP, as well as respiratory tract infection on three occasions. During the third flare, when she also developed cutaneous vasculitis, she agreed for prednisolone but refused other second-line agents. To date, she remained well with the maintenance of prednisolone 2.5 mg monotherapy for more than one year. The lessons from this case are (i) patients with LIP can be asymptomatic, (ii) LIP can precede symptoms of SS, and (iii) treatment decision for asymptomatic patients with abnormal imaging or patients with mild severity should be weighed between the risk of immunosuppression and risk of active disease.

Pattern of biopsy-proven renal disease in Sabah: A retrospective cross-sectional study over 3.5 years

Lee AV, Pang HC, Linus Lojikip S, Wong KW, Goh KW, Chan FS

Med J Malaysia, 2020 03;75(2):152-157.
PMID: 32281597

OBJECTIVES: To explore the epidemiological and histopathological patterns of glomerular diseases in Sabah.
METHODS: A state-wide cross-sectional study was conducted. There were 336 native renal biopsies in 296 eligible patients from 1st January 2013 to 30th June 2016. All patients aged ≥12 years with sufficient sampling (≥8 glomeruli) for histopathological assessment were included. Graft kidney biopsies, protocol-based biopsies and patients with uncertain demographics were excluded. Demographics of patients, clinical data, laboratory parameters prior to biopsy, and histology findings of renal biopsies were collected from local unit database and recorded into a standardised data collection form. Descriptive statistical analyses were employed and factors associated with Lupus nephritis (LN) were explored using logistic regression.
RESULTS: The mean age during biopsy was 34.53 years (Standard Deviation 0.759). Primary glomerulonephritis (PGN) accounted for 42.6% (126) of all native renal biopsies. The commonest cause of PGN was minimal change disease (38.9%, 49) followed by focal segmental glomerulosclerosis (33.3%, 42) and IgA nephropathy (14.3%, 18). LN is the leading cause for secondary glomerulonephritis (SGN) (87.2%, 136). Younger age (Odds Ratio, OR 0.978; 95% Confidence Interval, 95%CI 0.960, 0.996); female gender (OR 17.53; p<0.001); significant proteinuria (OR 132.0; p<0.001); creatinine level at biopsy (OR 11.26; p=0.004); positive antinuclear antibody (ANA) (OR 46.7; p<0.001); and ANA patterns (OR 8.038; p=0.018) were significant in predicting the odds of having LN.
CONCLUSION: This is the first epidemiology study of glomerular diseases in Sabah. The predominance of LN suggests lower threshold for renal biopsy in patients with suspected glomerular disorders. We have identified significant predictors for early detection and treatment of LN.

Fulltext Analysis of octamer-binding transcription factor-4 expression in oral leukoplakia

Tegginamani AS, Shivakumar VH, Kallarakkal TG, Ismail SM, Abraham MT, Bin Zamzuri AT

J Oral Maxillofac Pathol, 2020 09 09;24(2):400.
PMID: 33456258 DOI: 10.4103/jomfp.JOMFP_272_19

Background: Oral potentially malignant disorders have a risk for malignant transformation but are difficult to reliably identify and predict which patients are at the risk for malignant transformation. OCT4 has been hypothesized to play a key oncogenic driver in a variety of solid tumors. A deeper understanding of the aberrant molecular pathways which lead to carcinogenesis needs to be identified by the potential markers.
Aims: To assess the OCT4 stemness factor in oral leukoplakia for its potential risk to malignant transformation.
Settings and Design: 20 cases of oral leukoplakia were obtained from archives at Oral Cancer Research & Coordinating center (OCRCC) Malaysia Subjects and Methods: 20 cases of oral leukoplakia were assessed by OCT4 immunohistochemically. Oral squamous cell carcinoma was used as a control.
Result: no expression of OCT 4 was observed in any cases of oral leukoplakia.
Conclusion: The molecular mechanisms of Oct4 regulation and in particular of its switch on and off in tissues depends upon its microenvironment, which makes it challenging in fundamental and applied research fields of regenerative medicine and cancer therapy. It's better that patients should undergo multiple biopsies for the early detection of malignant transformation with close follow-up during the first two to three years, a large amount of work remains to be done with multi-marker panel investigation, as cure rates have remained constant over three decades.

Fulltext Synovial biopsy. A comparative study from Saudi Arabia and Malaysia

Sankaran-Kutty M, Das PK, Kannan Kutty M

Int Orthop, 1998;22(3):189-92.
PMID: 9728315 DOI: 10.1007/s002640050239

A comparative study of synovitis in Saudi Arabia and Malaysia was made with a view to determining any geographic variation in the incidence and pattern of the arthritides. The diagnostic spectrum in both series included pyogenic arthritis, rheumatoid arthritis, brucellar and tubercular arthritis, gout, pigmented villonodular synovitis, synovial chondromatosis and acute rheumatic fever. Date-palm thorn synovitis was observed only in the Saudi Arabian series. While brucellar and tuberculous arthritis were predominantly seen in Saudi Arabia, the incidence of rheumatoid arthritis, pigmented villonodular synovitis and acute suppurative arthritis was almost equal in both countries.
