    Percutaneous image-guided needle biopsy is typically performed in highly vascular organs or in tumours with rich macroscopic and microscopic blood supply. The main risks related to this procedure are haemorrhage and implantation of tumour cells in the needle tract after the biopsy needle is withdrawn. From numerous conducted studies, it was found that heating the needle tract using alternating current in radiofrequency (RF) range has a potential to minimize these effects. However, this solution requires the use of specially designed needles, which would make the procedure relatively expensive and complicated. Thus, we propose a simple solution by using readily available coaxial core biopsy needles connected to a radiofrequency ablation (RFA) generator. In order to do so, we have designed and developed an adapter to interface between these two devices. For evaluation purpose, we used a bovine liver as a sample tissue. The experimental procedure was done to study the effect of different parameter settings on the size of coagulation necrosis caused by the RF current heating on the subject. The delivery of the RF energy was varied by changing the values for delivered power, power delivery duration, and insertion depth. The results showed that the size of the coagulation necrosis is affected by all of the parameters tested. In general, the size of the region is enlarged with higher delivery of RF power, longer duration of power delivery, and shallower needle insertion and become relatively constant after a certain value. We also found that the solution proposed provides a low cost and practical way to minimizes unwanted post-biopsy effects.

    BACKGROUND: The non-alcoholic fatty liver disease (NAFLD) fibrosis score (NFS) is indeterminate in a proportion of NAFLD patients. Combining the NFS with liver stiffness measurement (LSM) may improve prediction of advanced fibrosis. We aim to evaluate the NFS and LSM in predicting advanced fibrosis in NAFLD patients.

    METHODS: The NFS was calculated and LSM obtained for consecutive adult NAFLD patients scheduled for liver biopsy. The accuracy of predicting advanced fibrosis using either modality and in combination were assessed. An algorithm combining the NFS and LSM was developed from a training cohort and subsequently tested in a validation cohort.

    RESULTS: There were 101 and 46 patients in the training and validation cohort, respectively. In the training cohort, the percentages of misclassifications using the NFS alone, LSM alone, LSM alone (with grey zone), both tests for all patients and a 2-step approach using LSM only for patients with indeterminate and high NFS were 5.0, 28.7, 2.0, 2.0 and 4.0 %, respectively. The percentages of patients requiring liver biopsy were 30.7, 0, 36.6, 36.6 and 18.8 %, respectively. In the validation cohort, the percentages of misclassifications were 8.7, 28.3, 2.2, 2.2 and 8.7 %, respectively. The percentages of patients requiring liver biopsy were 28.3, 0, 41.3, 43.5 and 19.6 %, respectively.

    CONCLUSIONS: The novel 2-step approach further reduced the number of patients requiring a liver biopsy whilst maintaining the accuracy to predict advanced fibrosis. The combination of NFS and LSM for all patients provided no apparent advantage over using either of the tests alone.

    Tuberculous prostatitis is an uncommon form of tuberculosis infection. It is commonly seen in immunocompromised patients and in those of middle or advanced age. The diagnosis is often not straight forward due to the nature of its presentation. We report a case of tuberculous prostatitis in a young, healthy and immunocompetent patient, who initially presented with respiratory features, followed by episodes of seizures and testicular swelling. He was finally diagnosed with tuberculous prostatitis after prostatic biopsy. This case illustrates that in a high TB prevalence environment, when symptoms warrant, there should be a high clinical suspicion coupled with a thorough approach in order to arrive at a correct diagnosis of TB prostatitis.

    Langerhans cell histiocytosis (LCH) is rarely encountered in ophthalmology practice. It is a spectrum of disorder characterized by accumulation of histiocytes in various tissues. Diagnosis is challenging as it may simulate periorbital hematoma, rhabdomyosarcoma, and neuroblastoma. We report a case of unifocal LCH with orbital extension. Diagnosis was obtained from incisional biopsy, and histopathological examination showed numerous histiocytes with eosinophilic infiltrations. The presence of Langerhans cells was confirmed by the presence of protein S-100, CD1a, and/or Langerin (CD207). Treatment depends on the degree of organ involvement. She responded well to cytotoxic drugs and steroids. This emphasized that prompt tissue diagnosis is crucial for early management.

    Patients with lung cancer may present with respiratory and systemic symptoms. However,
    cutaneous metastases from primary lung cancer is a rare phenomenon, especially in women,
    that signifies a poor prognosis. This paper reported a case regarding a 71-year-old woman
    who was first presented with a cutaneous nodule over the year. Her condition was further
    progressed to multiple lesions on the back and abdomen, dyspnoea, haemoptysis and weight
    loss. The results of the skin lesion biopsy exhibited metastatic lung adenocarcinoma with
    positive immunohistochemistry for thyroid transcription factor 1 (TTF1) and cytokeratin 7 (CK7). Computed tomography (CT) scan was conducted, and it revealed a left upper lobe lung
    mass. The patient was subsequently scheduled for additional management, but she had
    succumbed to complications of pulmonary embolism before the necessary interventions could
    be provided. In this particular case presentation, the biopsy of cutaneous lesions obtained had
    revealed an undiagnosed primary malignancy.

    BACKGROUND: Globally, research on oral and maxillofacial lesions among newborns and infants remains limited.

    AIM: To describe demographic patterns, histopathological findings, and locations of oral and maxillofacial lesions in newborns (birth-1 month) and infants (>1 month-2 years) reported over 51 years.

    DESIGN: A retrospective cross-sectional study on histopathological records of newborns and infants was conducted. Patients' demographic characteristics (age, gender, and race), histopathological diagnosis, and lesion's location were gathered. Pearson's chi-square or Fisher's exact test was performed to determine associations between demographic characteristics and different categories of lesions.

    RESULTS: Out of 66,546 specimens received, 0.44% (290 specimens) were from patients aged 2 years and younger (27 newborns and 263 infants). The most common category was inflammatory/reactive (44.2%), followed by tumour/tumour-like (42.0%), cystic/pseudocystic (6.6%), and miscellaneous lesions (5.5%). Mucous extravasation cysts (23.4%) and Langerhans cell histiocytosis (7.2%) were the most common histopathological diagnoses. Tumour/tumour-like lesions were significant in newborns (P = .021), and majority were congenital epulis (40.7%). Inflammatory/reactive lesions were significantly higher in male (P = .025) and infants (P =

    This paper attempts to review epidemiological studies of oral cancer and precancer in Malaysia. The defmitions of prevalence, incidence, risk habits and oral cancer and precancers were discussed to better understand' the different types of studies conducted, which would be important in making comparisons between studies. Currently, epidemiological data on oral cancer in Malaysia are sketchy. The only incidence data for oral cancer in Malaysia was reported by Hirayama in 1966, 35 years ago. He estimated that 3.1 new cases per 100,000 population were diagnosed for the year 1963. A number of histopathological data of oral and maxillofacial biopsies were reported. Oral cancer accounted for one-fifth of all oral biopsies. A national study on oral mucosal lesions in Malaysia carried out in 1993/4 reported that there was a variation seen in the occurrence of oral premalignancy among the ethnic groups. The Indians and the indigenous people of Sabah and Sarawak were identified as high risk groups for oral cancer and precancer. It was also observed that both of the ethnic groups chewed betel quid. In conclusion, the epidemiological studies have provided useful data, which may be used in planning for future oral health programmes and research towards enhancing Malaysia's on-going effort in preventing the occurrence of these diseases.

    To review the demographics, management and outcome of patients undergoing parotidectomy at a tertiary center. A total of 76 patients who underwent parotidectomies from January 1996 to December 2005 at the ORL department of our center were reviewed. All clinical, operative, postoperative, histology data were gathered and reviewed. Fine-needle aspiration cytology (FNAC) was diagnostic in 90% of patients with a sensitivity of 76% and specificity of 96%. Twenty-one patients had malignant tumours and the rest had benign or inflammatory lesions. There were a total of 48 superficial and 28 total parotidectomies performed. Facial nerve palsy occurred in 30 (39%) patients with 4% permanent palsy and 35% temporary palsy. The recurrence rate of pleomorphic adenoma was 2.6%. FNAC and CT scan were performed prior to the surgery were useful guidance in planning the operation but clinical judgment is more important. The most common surgery performed was superficial parotidectomy and the most common cause was due to pleomorphic adenoma. The incidence of complications and recurrence of tumour are comparable to other international studies. Prior knowledge of anatomy and careful planning is needed to decrease the incidence of facial nerve palsy.

    Computed tomography (CT) fluoroscopy is able to give real time images to a physician undertaking minimally invasive procedures such as biopsies, percutaneous drainage, and radio frequency ablation (RFA). Both operators executing the procedure and patients too, are thus at risk of radiation exposure during a CT fluoroscopy.This study focuses on the radiation exposure present during a series of radio frequency ablation (RFA) procedures, and used Gafchromic film (Type XR-QA; International Specialty Products, USA) and thermoluminescent dosimeters (TLD-100H; Bicron, USA) to measure the radiation received by patients undergoing treatment, and also operators subject to scatter radiation.The voltage was held constant at 120 kVp and the current 70mA, with 5mm thickness. The duration of irradiation was between 150-638 seconds.Ultimately, from a sample of 30 liver that have undergone RFA, the study revealed that the operator received the highest dose at the hands, which was followed by the eyes and thyroid, while secondary staff dosage was moderately uniform across all parts of the body that were measured.

    Thyroglossal duct cyst (TDC) is a developmental anomaly that usually appears in early childhood. The common presentation is midline swelling of the neck, which moves with both tongue protrusion and deglutition. Diagnosis is usually clinical and radiological. Fine needle aspiration cytology (FNAC) can be used as a tool for the exclusion of malignancy in adult patients. In some cases thyroid scan is done to rule out the presence or absence of the normal thyroid gland. A complete work-up is mandatory before cyst removal given that it contains only thyroid tissue. We report the case of a 32-year-old woman with only thyroid tissue in thyroglossal duct cyst.

    INTRODUCTION: Anaplastic lymphoma kinase-positive (ALK+) anaplastic large cell lymphoma (ALCL) with a non-common pattern can be diagnostic challenging. Pathologists can be unavoidably and unintentionally blind to non-descript tumor cells in a lymphohistiocytic- (LH) or small-cell (SC)-pattern. We report a case of primary systemic ALK+ ALCL with a SC pattern that presented as secondary gastric lesions with a mixed LH and SC pattern that was masqueraded as inflammatory lesions.

    CASE REPORT: A 34-year-old woman with intractable epigastric pain was referred to have repeated endoscopy with biopsy. She was found to multiple gastric erosions and nodules that were diagnosed as inflammatory lesions both endoscopically and histologically. Meanwhile, she developed an acute onset of severe back pain associated with a pathologic compression fracture in the T3 thoracic vertebral body. Imaging studies disclosed a disseminated systemic disease involving abdominopelvic lymph nodes and cervical and thoracic vertebral bodies. The needle biopsy of the pelvic lymph node disclosed diffuse proliferation of monomorphic small round cells that were diffusely positive for CD30 and ALK. A diagnosis of ALK+ ALCL with a monomorphic SC pattern was rendered.

    DISCUSSION: A retrospective review of the gastric biopsies with the aid of immunohistochemistry enabled us to recognise the presence of lymphomatous infiltrates with a mixed LH and SC pattern in every piece of gastric biopsies that were repeatedly misdiagnosed as inflammatory lesions. This case illustrates a significant diagnostic pitfall of the LH- and SC-patterns in ALK+ ALCL, in which the tumour cells featuring lymphoid, plasmacytoid or histiocytoid appearance can be masqueraded as inflammatory cells.

    Oral cancer is one of the common cancer cases identified in the developing countries. Genetic mutation and overexpression of certain genes and proteins have been associated in the development of this cancer. Notch signalling pathway is normally involved in controlling the development process of vertebrates and invertebrates; however, deregulation of this pathway was found to be responsible in the formation of certain cancers including oral cancers. Activation of this pathway requires binding of the ligands to its receptors. Four NOTCH receptors (NOTCH 1, 2, 3 and 4) have been identified in mammals. Disruptions within these molecules might interfere with the normal functions of Notch signalling pathway. Hence, this study was conducted to detect mutations of NOTCH1 and NOTCH2 receptor genes which might be occurring in the oral cancer cases obtained from the local population. DNA extracted from fresh-frozen tissue biopsy of the tongue and buccal mucosa from 10 confirmed cases of oral cancer were subjected for polymerase chain reaction (PCR) amplification using the specific sets of primers. The PCR products were sent for sequencing before final results were analysed.
    Due to time and cost limitation, only two out of four NOTCH receptor genes; NOTCH1 and NOTCH2, were used in this analysis. The results revealed absence of nucleotide changes for both NOTCH receptor genes amplified from these oral cancer samples. More samples and further analysis looking into other regions in these genes are required to conclude the involvement of NOTCH receptor genes mutation in causing oral cancer.

    Background: Thyroid swelling or goitre is a common condition, either asymptomatic or symptomatic. The
    diagnosis is usually established by ultrasound or fine needle aspiration cytology (FNAC) as a gold standard.
    The sensitivity of the test is inversely related to increasing size of the nodule. The objective of this study is
    to evaluate the accuracy of FNAC especially in cases of large goitre.

    Material and methods: This is a
    retrospective study on patients who underwent thyroidectomy between January 2000 to December 2007 for
    solitary or dominant nodular goitre. The analysis was made only on those patients with complete data on
    FNAC and histology.

    Result: There were 235 patients, but only 161 patients were analysed after excluding
    the suspicious and inadequate sample. The patients’ mean age was 42.1 year old (21 to 60). The size of the
    thyroid nodule ranged from 2.1 to 5.0 cm (mean = 3.9 cm). The overall sensitivity was 67.4% and the overall
    accuracy was 86.3%. The accuracy of FNAC according to the sizes above and below the value were as
    follows; 2 cm (72.2% vs. 88.1%); 3 cm (88.0% vs. 87.4%) ; 4 cm (86.6% vs. 84.4%) ; 5 cm (87.3% vs. 78.8%).
    This was most obvious in the sensitivity of the FNA which also showed reducing trend as the nodules
    increased in size.

    Conclusion: FNAC is an essential diagnostic tool in the management of nodular goitre.
    Our study showed that the accuracy of FNAC decreased as the size of the nodule getting bigger. Cautious
    approach should be taken in the management of large goitre and decision should not be based only on the
    result of FNAC.

    Marjolin's ulcer is a rare and often overlooked diagnosis which can be encountered by a variety of specialities. Majority of the literatures describe long latency period of 11 to 75 years. The authors present two unusual cases of rapid progression to Marjolin's ulcer in patients with previously negative biopsy 8- and 10-month prior. This highlights the importance for clinicians to have a high degree of suspicion when encountered with any non-healing wound, especially one who's symptomatology and morphological features have undergone an acute change. Even with previous negative biopsy, patients should still be followed-up closely and clinicians should not hesitate to perform re-biopsy if the suspicion arises.

    We present a young adult female with symptoms of acute tonsillitis and tender cervical lymphadenopathy. Despite a full course of oral antibiotics, she had persistent left lower cervical lymphadenopathy measuring 2.0 x 1.5 cm at 2 weeks post-treatment. Rigid and flexible scope examinations did not reveal any abnormalities in the nasopharynx, oropharynx or hypopharynx. Tuberculosis tests were negative and blood index results were normal. Fine needle aspiration cytology revealed a non-specific granulomatous inflammatory process. Excisional lymph node biopsy was performed, and the patient was diagnosed as having Kikuchi's Disease (KD). We would like to highlight the diagnostic challenges in detecting this condition and the importance of differentiating KD from tuberculosis and malignant lymphoma, the latter of which requires aggressive treatment.
