There has been a growing awareness of the association between papillary thyroid carcinoma and familial adenomatous polyposis (FAP). The cases of four young patients with papillary thyroid carcinoma occurring with FAP are presented. Three patients underwent surgery to provide specimens for detailed histological examination. The surgical specimens showed well-encapsulated multicentric tumours exhibiting a predominantly papillary architectural growth pattern. In some areas, follicular architecture and cribriform patterns were noted. Atypical areas of spindle cells in a trabecular or solid configuration, which are not normally seen in classical papillary thyroid carcinoma, were evident. Malignant cells exhibited a graduation of cuboidal to tall cells with abundant amphophilic cytoplasm. The nuclei did not exhibit the typical nuclear clearing as seen in papillary thyroid carcinoma, but nuclear grooving and inclusions were noted. Psammoma bodies were not seen in any of the specimens. In a limited review of these patients, features such as young age at presentation, multicentricity and unusual histology suggest that thyroid carcinoma associated with FAP may represent a distinct form of thyroid cancer.

Currarino triad with dual pathology in the presacral mass: report of a case

Thambidorai CR, Muin I, Razman J, Zulfiqar A

Dis Colon Rectum, 2003 Jul;46(7):974-7.

PMID: 12847376

PURPOSE: Currarino triad, which comprises anorectal stenosis, anterior sacral defect, and a presacral mass, is an uncommon cause of constipation in children and adults. The presacral mass in this triad is most often caused by an anterior sacral meningocele, a teratoma, or an enterogenous cyst, but rarely may be caused by dual pathology. A neonate with Currarino triad and dual pathology in the presacral mass is described in this report.

METHOD: A male Chinese neonate, who presented with abdominal distention and constipation on the second day of life, was found to have features of Currarino triad. Colostomy was done in the neonatal period, and the presacral mass was excised by posterior sagittal perineal approach at the age of six months.

RESULTS: The excised presacral mass consisted of an anterior meningocele and a teratoma. The patient continued to have constipation during follow-up and required anorectoplasty to correct residual anorectal stenosis. At the time of this report the patient was three years old and growing normally with normal anorectal function.

DISCUSSION: Of a total of about 200 cases of complete Currarino triad found in the literature, in only 22 patients did the presacral mass contain both meningocele and teratoma. The features of these 22 patients and the current views on the surgical management of Currarino triad are discussed.

Chow HT

Oral Surg Oral Med Oral Pathol Oral Radiol Endod, 1998 Nov;86(5):573-7.

PMID: 9830650

The odontogenic keratocyst has been well documented and extensively studied. It is of particular interest because of its high recurrence rate and aggressive nature. The material for this study consisted of 70 cases of odontogenic keratocysts in predominantly ethnic Chinese patients who were treated from 1981 to 1996. The cases were retrospectively studied to compare characteristics of the lesion in this population with those in previous reports. Most of the patients in this series were 21 to 30 years of age. Association with an impacted mandibular third molar was found in more than 50% of the cases. The recurrence rate was 20% for 35 patients with a follow-up period of at least 5 years. The follow-up period for the whole series ranged from 1 to 16 years. Treatment was surgical enucleation with peripheral ostectomy. There were no significant differences in characteristics with respect to presentation and prognosis between this series and those described in previous publications.

Malignant obstruction of superior vena cava: Endovascular stenting using Y-configuration stent in stent technique

Noor Khairiah AK, Mohamad Nazrulhisham MN, Hazman MN

Med J Malaysia, 2018 12;73(6):407-409.

PMID: 30647215

Malignant intrathoracic disease is the commonest cause of superior vena cava (SVC) obstruction. Life threatening SVC obstruction with intense dyspnoea requires urgent treatment. SVC stenting has been developed in recent years which results in rapid relief of the obstruction. The Yconfiguration technique has been reported to provide support for all three limbs of the bifurcation to prevent restenosis. At present, there are limited reports on the use of Y-configuration stent in stent techniques for endovascular stenting in malignant SVC obstruction. We share our clinical experience of two patients who received balloon-mounted stents using this technique.

Impact of fluorine-18 fluorodeoxyglucose positron emission tomography on diagnosis and antimicrobial utilization in patients with high-risk febrile neutropenia

Koh KC, Slavin MA, Thursky KA, Lau E, Hicks RJ, Drummond E, et al.

Leuk Lymphoma, 2012 Oct;53(10):1889-95.

PMID: 22448920 DOI: 10.3109/10428194.2012.677533

Early and targeted antimicrobial therapy improves outcomes in patients with febrile neutropenia (FN). We evaluated the impact of fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) on antimicrobial utilization in the management of FN. A cohort of patients with FN and hematological malignancy was identified. Cases (in whom FDG-PET was performed, n = 37) were compared with controls (in whom conventional investigations excluding FDG-PET were performed, n = 76). An underlying cause for FN was determined in 94.6% of cases, compared to 69.7% of controls. FDG-PET had a significant impact on antimicrobial utilization compared to conventional imaging (35.1% vs. 11.8%; p = 0.003), and was associated with shorter duration of liposomal amphotericin-B therapy for systemic fungal infection (median 4.0 days cases vs. 10.0 days controls; p = 0.001). Cases had a longer length of hospitalization (p = 0.016). In the management of patients with high-risk FN, FDG-PET improves diagnostic yield and allows rationalization of antifungal therapy. The impact upon healthcare costs associated with antimicrobial therapy for FN requires further evaluation.

Al-Talib H, Hasan H, Yean CY, Al-Ashwal SM, Ravichandran M

Jpn J Infect Dis, 2011;64(1):58-60.

PMID: 21266757

Panton-Valentine leukocidin (PVL) is a cytotoxin which causes leukocyte destruction and tissue necrosis. Although it is produced by fewer than 5% of Staphylococcus aureus strains, PVL-producing S. aureus is emerging as a serious problem worldwide. There has been a marked increase in the incidence of necrotizing lung infections with a very high mortality associated with these strains. This report describes a fatal case of hospital-acquired necrotizing pneumonia caused by PVL-positive methicillin-susceptible S. aureus in a patient with a brain tumor.

The Use of Methylphenidate for Physical and Psychological Symptoms in Cancer Patients: A Review

Andrew BN, Guan NC, Jaafar NRN

Curr Drug Targets, 2018;19(8):877-887.

PMID: 28322161 DOI: 10.2174/1389450118666170317162603

BACKGROUND: One of the goals of cancer treatment is symptoms management especially at the end stage. The common symptoms in cancer include pain, fatigue, depression and cognitive dysfunction. The available treatment options for symptom management are limited. Methylphenidate, a psychostimulant, may be of benefit for these patients. In this report, we review the use of methylphenidate for symptoms control in cancer patients.

METHOD: Electronic literature search on PubMed was conducted using the following keywords: methylphenidate, cancer, carcinoma, oncology, oncological and tumour. We identified forty two relevant studies and publications on the use of methylphenidate in cancer patients to be included in this review.

RESULTS: Methylphenidate was found to have some evidence in reducing opioid-induced sedation, improving cognitive symptoms and reduction of fatigue in cancer patients. Nevertheless, the results were inconsistent due to variations in the study populations, study design and outcome measures, among others. There was minimal evidence on its use in treating depression. Otherwise, methylphenidate was generally well-tolerated by patients.

CONCLUSION: This review potentially supports the use of methylphenidate for opioid-induced sedation, cognitive decline and fatigue in cancer patients. Further placebo-controlled trials would help in strengthening the evidence for this treatment.

PMID: 34261515 DOI: 10.1186/s13014-021-01851-0

BACKGROUND: Tooth extraction post radiotherapy is one of the most important risk factors of osteoradionecrosis of the jawbones. The objective of this study was to determine the predictors of osteoradionecrosis (ORN) which were associated with a dental extraction post radiotherapy.

METHODS: A retrospective analysis of medical records and dental panoramic tomogram (DPT) of patients with a history of head and neck radiotherapy who underwent dental extraction between August 2005 to October 2019 was conducted.

RESULTS: Seventy-three patients fulfilled the inclusion criteria. 16 (21.9%) had ORN post dental extraction and 389 teeth were extracted. 33 sockets (8.5%) developed ORN. Univariate analyses showed significant associations with ORN for the following factors: tooth type, tooth pathology, surgical procedure, primary closure, target volume, total dose, timing of extraction post radiotherapy, bony changes at extraction site and visibility of lower and upper cortical line of mandibular canal. Using multivariate analysis, the odds of developing an ORN from a surgical procedure was 6.50 (CI 1.37-30.91, p = 0.02). Dental extraction of more than 5 years after radiotherapy and invisible upper cortical line of mandibular canal on the DPT have the odds of 0.06 (CI 0.01-0.25, p

Wong SK, Mohamad NV, Jayusman PA, Shuid AN, Ima-Nirwana S, Chin KY

Aging Male, 2019 Jun;22(2):89-101.

PMID: 29508640 DOI: 10.1080/13685538.2018.1448058

Selective estrogen receptor modulators (SERMs) represent a class of drugs that act as agonist or antagonist for estrogen receptor in a tissue-specific manner. The SERMs drugs are initially used for the prevention and treatment of osteoporosis in postmenopausal women. Bone health in prostate cancer patients has become a significant concern, whereby patients undergo androgen deprivation therapy is often associated with deleterious effects on bone. Previous preclinical and epidemiological findings showed that estrogens play a dominant role in improving bone health as compared to testosterone in men. Therefore, this evidence-based review aims to assess the available evidence derived from animal and human studies on the effects of SERMs on the male skeletal system. The effects of SERMs on bone mineral density (BMD)/content (BMC), bone histomorphometry, bone turnover, bone strength and fracture risk have been summarized in this review.

Fulltext Establishing an Animal Model of Secondary Osteoporosis by Using a Gonadotropin-releasing Hormone Agonist

Mohamad NV, Che Zulkepli MAA, May Theseira K, Zulkifli N, Shahrom NQ, Ridzuan NAM, et al.

Int J Med Sci, 2018;15(4):300-308.

PMID: 29511366 DOI: 10.7150/ijms.22732

Introduction: Orchidectomy is currently the preferred method to induce bone loss in preclinical male osteoporosis model. Gonadotropin-releasing hormone (GnRH) agonists used in prostate cancer treatment can induce testosterone deficiency but its effects on bone in preclinical male osteoporosis model are less studied. Objective: This study aimed to evaluate the skeletal effect of buserelin (a GnRH agonist) in male rats and compare it with orchidectomy. Methods: Forty-six three-month-old male Sprague-Dawley rats were divided into three experimental arms. The baseline arm (n=6) was sacrificed at the onset of the study. In the buserelin arm, the rats received a daily subcutaneous injection of either normal saline (n=8), buserelin acetate at 25 µg/kg (n=8) or 75 µg/kg (n=8). In the orchidectomy arm, the rats were either sham-operated (n=8) or orchidectomized (n=8). All groups underwent in-vivo X-ray micro-computed tomography scanning at the left proximal tibia every month. Blood was collected at the beginning and the end of the study for testosterone level evaluation. The rats were euthanized after the three-month treatment. The femurs were harvested for biomechanical strength and bone calcium determination. Results: The results showed that buserelin at both doses caused a significant decline in testosterone level and deterioration in bone microstructure (p<0.05), but did not affect bone calcium content (p>0.05). Buserelin at 25 µg/kg decreased displacement and strain of the femur significantly (p<0.05). Similar changes were observed in the orchidectomized group compared to the sham-operated group but without any significant changes in biomechanical strength (p>0.05). Conclusion: Buserelin can induce testosterone deficiency and the associated deterioration of bone microarchitecture similar to orchidectomy in three months. However, it may require a longer time to show significant effects on bone strength and mineral content.

Fulltext Detection of Strongyloides stercoralis infection among cancer patients in a major hospital in Kelantan, Malaysia

Zueter AM, Mohamed Z, Abdullah AD, Mohamad N, Arifin N, Othman N, et al.

Singapore Med J, 2014 Jul;55(7):367-71.

PMID: 25091885

INTRODUCTION: Strongyloidiasis is one of the most commonly neglected but clinically important parasitic infections worldwide, especially among immunocompromised patients. Evidence of infection among immunocompromised patients in Malaysia is, however, lacking. In this study, microscopy, real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assays (ELISAs) were used to detect Strongyloides stercoralis (S. stercoralis) infection among cancer patients in a Malaysian hospital.

METHODS: A total of 192 stool and serum samples were collected from cancer patients who were receiving chemotherapy with or without steroid treatment at a hospital in northeastern Malaysia. Stool samples were examined for S. stercoralis using parasitological methods and real-time PCR. Serology by ELISA was performed to detect parasite-specific immunoglobulin G (IgG), IgG4 and immunoglobulin E (IgE) antibodies. For comparison, IgG4- and IgG-ELISAs were also performed on the sera of 150 healthy individuals from the same area.

RESULTS: Of the 192 samples examined, 1 (0.5%) sample was positive for S. stercoralis by microscopy, 3 (1.6%) by real-time PCR, 8 (4.2%) by IgG-ELISA, 6 (3.1%) by IgG4-ELISA, and none was positive by IgE-ELISA. In comparison, healthy blood donors had significantly lower prevalence of parasite-specific IgG (2.67%, p < 0.05) and IgG4 (2.67%, p < 0.05) responses.

CONCLUSION: This study showed that laboratory testing may be considered as a diagnostic investigation for S. stercoralis among immunocompromised cancer patients.

PMID: 19644631

Thyroid cancer is the most common among all endocrine malignancies. The worldwide prevalence of goitre in the general population is estimated at 4-7 percent and the incidence of malignancy in goitrous thyroid is about ten percent. It is postulated that goitrous thyroid is a precursor lesion to the development of malignant thyroid diseases. As Sarawak is a state well known for endemic goitre, this study focused on establishing the incidence of thyroid malignancy among goitrous thyroid swellings.

What doctors know about cancer pain management: an exploratory study in Sarawak, Malaysia

Devi BC, Tang TS, Corbex M

J Pain Palliat Care Pharmacother, 2006;20(2):15-22.

PMID: 16702132

Effective cancer pain management is influenced by the attitudes and knowledge of treating physicians. A survey was conducted among the total population of government hospital doctors of Sarawak to study the barriers to cancer pain management. Two hundred and fifty-three respondents (83%) completed the survey. The study results highlight that knowledge about cancer pain management was low and barriers to morphine prescription were high. A majority of doctors were deterred from using morphine because of fear of addiction (36.5%) and respiratory depression (53.1%). Only 16.2% of the doctors chose the oral mode of administration to treat pain, furthermore 25% prescribed morphine on "PRN" basis. Doctors with undergraduate study in oncology consistently answered better suggesting that the situation can be improved by education. This study showed that barriers to morphine prescription and knowledge deficit amongst government doctors in Sarawak are strong but similar to those reported in western countries few years ago.
