Fulltext Salmonella Thyroid Abscess Treated by Serial Aspiration: Case Report and Literature Review

Vengathajalam S, Retinasekharan S, Mat Lazim N, Abdullah B

Indian J Otolaryngol Head Neck Surg, 2019 Oct;71(Suppl 1):823-826.
PMID: 31742073 DOI: 10.1007/s12070-019-01654-6

Thyroid abscesses are the most rare conditions of the thyroid gland but it could be potentially life threatening. Most patients are immunocompromised or has an underlying chronic thyroid disorder. We report a case of a 58 year-old lady with underlying uncontrolled diabetes mellitus and a long standing uninvestigated goiter who presented with lethargy, a new anterior neck swelling with dysphagia and change of voice. Ultrasound and computed tomography were performed and showed collection with multiple air pockets in the right thyroid lobule extending to the anterior mediastinum. She was started on intravenous antibiotics and underwent serial bedside aspiration. Her symptoms improved and complete resolution was achieved after serial aspirations and antibiotics.

Fulltext Incidence of thyroid malignancy among goitrous thyroid lesions from the Sarawak General Hospital 2000-2004

Htwe TT, Hamdi MM, Swethadri GK, Wong JO, Soe MM, Abdullah MS

Singapore Med J, 2009 Jul;50(7):724-8.
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.

Fulltext Expression of Galectin-3 and Galectin-7 in thyroid malignancy as potential diagnostic indicators

Than TH, Swethadri GK, Wong J, Ahmad T, Jamil D, Maganlal RK, et al.

Singapore Med J, 2008 Apr;49(4):333-8.
PMID: 18418527

It has been suggested that Galectin-3 (Gal-3) and Galectin-7 (Gal-7) are potential tumour markers for differentiating thyroid carcinoma from its benign counter part. Galectins are beta-galactoside-binding proteins with Gal-3 being a redundant pre-mRNA splicing factor. They are supposed to be p53-related regulators in cell growth and apoptosis, being either anti-apoptotic or pro-apoptotic. Although the value of Gal-3 has been studied extensively, there is little knowledge regarding the expression of Gal-7 in thyroid malignancy.

Zuckerkandl's tubercle of the thyroid gland in association with pressure symptoms: a coincidence or consequence?

Hisham AN, Aina EN

Aust N Z J Surg, 2000 Apr;70(4):251-3.
PMID: 10779054

BACKGROUND: The Zuckerkandl's tubercle (ZT) of the thyroid gland is a well-described anatomical landmark, but few studies have clearly defined its association with pressure symptoms.
METHODS: Sixty-six consecutive patients who had primary thyroid surgery were prospectively included in the present study between late January and early August 1998.
RESULTS: A total of 96 capsular dissections were performed at thyroid surgery. Grades two and three ZT were recognized in 77 (80.2%) dissections. In general 49 (63.6%) of them were associated with significant pressure symptoms. In 43 (87.8%) of the dissections with pressure symptoms, grade 3 ZT was observed (mean weight of goitre: 154.8 g). Interestingly in this group, 16 (37.2%) patients with pressure symptoms had a goitre that was < 100 g and in one patient it was only 21 g.
CONCLUSIONS: The pressure symptom of the thyroid gland does not always appear to be due to the large size of the goitre. In a relatively small-size goitre the ZT may cause significant pressure symptoms. Observations in the present study supported a strong association of enlarged ZT with pressure symptoms. We believe this is unlikely to be simply a coincidence but rather a consequence of the enlarged tubercle. Nonetheless a prospective randomized study is called for to allow meaningful and objective evidence to be drawn.

Racial disparity in the prevalence of thyroid disorder during pregnancy

Sakinah SO, Khalid BA, Aishah AB

Ann Acad Med Singap, 1993 Jul;22(4):563-6.
PMID: 8257059

A study to determine the prevalence of goitre and abnormal thyroid status during pregnancy in Malaysian women was conducted. Two hundred and three women (Malay = 85, Chinese = 47 and Indian = 71) in the third trimester and with no known thyroid disease were studied. There was a marked racial disparity in the prevalence of goitre: Indian 61%, Malay 28% and Chinese 29% (p = 0.001). The serum thyrotropic hormone (TSH) was significantly higher in Indians (median: 1.36 uIU/ml) compared to Malays (1.14 uIU/ml, p = 0.009). The serum albumin was also significantly lower in Indians (mean +/- sd; 36.12 +/- 3.9 mmol/l) compared to Malays (39.3 +/- 4.8 mmol/l) or Chinese (39.1 +/- 5.2) (p < 0.001). Thyroid antibody was detected in 14.6% of these women with no significant racial difference in its prevalence. Three women were found to be thyrotoxic but none were hypothyroid. This study found a high prevalence of goitre among the pregnant Indian women, probably related to the protein malnutrition state. The high prevalence of positive thyroid antibody in our population indicates that a high percentage of women are at risk of developing postpartum thyroiditis.

Fine needle aspiration cytology of the thyroid--a review of experience in 1853 cases

Jayaram G, Razak A, Gan SK, Alhady SF

Malays J Pathol, 1999 Jun;21(1):17-27.
PMID: 10879275

1853 thyroid lesions subjected to cytological sampling (either by the fine needle aspiration or fine needle capillary sampling technique) from January 1992 to December 1997 at the University Hospital, Kuala Lumpur, were reviewed. Nodular goitre was the most common thyroid lesion needled (67.35%). Among the neoplastic lesions, follicular neoplasms predominated (64%), followed by papillary carcinoma (29.4%). In 325 cases, partial or total thyroidectomy had been done, providing material for histological review and cyto-histological correlation. Cytological diagnosis was found to have high sensitivity and specificity rates of over 75%. Besides, most non-neoplastic thyroid lesions could be diagnosed on cytology. The scope of cytology in the diagnosis of lymphomas, anaplastic and metastatic tumours rendered diagnostic biopsies (or thyroidectomy) unnecessary in these cases. Being a cost-effective technique and having the capacity to provide exact morphological diagnosis in a large variety of thyroid lesions, cytology is obviously the method of choice in the assessment of thyroid nodules.

PMID: 24394503

Although endemic goitre is no longer a major public health problem in Malaysia, iodine deficiency still remains a significant problem in a few remote settlements. The aim of this study was to determine the effectiveness of iodized oil intervention in the prevention of endemic goitre among the indigenous people in Malaysia. A pretest and post-test controlled trial was conducted among primary schoolchildren and pregnant mothers in Lasah, Sungai Siput and Perak. Legap Post and Yum Post were selected as the intervention areas, while Perwor Post and Poi Post were taken as controls. The variables studied included thyroid hormone concentrations, thyroid volume, urinary iodine excretions and mental performance. A baseline and two follow-up visits were conducted in both intervention and control areas. Intervention subjects were given iodized oil in the form of capsules which were taken orally (Laboratoire Guerbet, Paris, France). There was a significant increase in serum thyroxine hormone (T4) concentrations (p<0.0001) and a significant decrease in thyroid stimulating hormone (TSH) concentrations (p<0.05) in the schoolchildren following the intervention, however, pregnant mothers did not show any significant changes in T4 and TSH concentrations. Thyroid size was significantly reduced in both groups (p<0.05). Urinary iodine excretions showed a significant increase in both groups following the intervention (p<0.01). However, mental performance in schoolchildren was not affected. In conclusion, iodized oil (oral) is effective in reducing thyroid size, as well as improving the supply of iodine among schoolchildren and pregnant mothers in endemic goitre areas; however, its long-term effects need to be monitored closely. This method can be considered as an alternative while awaiting national coverage for the salt iodization program.

Fulltext Iodine deficiency status and iodised salt consumption in Malaysia: findings from a national iodine deficiency disorders survey

Selamat R, Mohamud WN, Zainuddin AA, Rahim NS, Ghaffar SA, Aris T

Asia Pac J Clin Nutr, 2010;19(4):578-85.
PMID: 21147721

A nationwide cross-sectional school-based survey was undertaken among children aged 8-10 years old to determine the current iodine deficiency status in the country. Determination of urinary iodine (UI) and palpation of the thyroid gland were carried out among 18,012 and 18,078 children respectively while iodine test of the salt samples was done using Rapid Test Kits and the iodometric method. The results showed that based on WHO/ ICCIDD/UNICEF criteria, the national median UI was 109 μg/L [25th, 75th percentile (67, 166)] showing borderline adequacy. The overall national prevalence of iodine deficiency disorders (IDD) with UI<100 μg/L was 48.2% (95% CI: 46.0, 50.4), higher among children residing in rural areas than in urban areas. The highest prevalence of UI<100 μg/L was noted among the aborigines [(81.4% (95% CI: 75.1, 86.4)]. The national total goitre rate (grade 1 and grade 2 goitre) was 2.1%. Of 17,888 salt samples brought by the school children, 28.2% (95% CI: 26.4, 30.2) were found to have iodine content. However, the overall proportion of the households in Malaysia using adequately iodised salt as recommended by Malaysian Food Act 1983 of 20-30 ppm was only 6.8% (95% CI: 5.1, 9.0). In conclusion, although a goitre endemic was not present in Malaysia, almost half of the states in Peninsular Malaysia still have large proportion of UI level <100 μg/L and warrant immediate action. The findings of this survey suggest that there is a need for review on the current approach of the national IDD prevention and control programme.

Local versus WHO/International Council for Control of Iodine Deficiency Disorders-recommended thyroid volume reference in the assessment of iodine deficiency disorders

Foo LC, Zulfiqar A, Nafikudin M, Fadzil MT, Asmah AS

Eur. J. Endocrinol., 1999 Jun;140(6):491-7.
PMID: 10366404

Iodine deficiency endemia is defined by the goitre prevalence and the median urinary iodine concentration in a population. Lack of local thyroid volume reference data may bring many health workers to use the European-based WHO/International Council for Control of Iodine Deficiency Disorders (ICCIDD)-recommended reference for the assessment of goitre prevalence in children in different developing countries. The present study was conducted in non-iodine-deficient areas in Malaysia to obtain local children's normative thyroid volume reference data, and to compare their usefulness with those of the WHO/ICCIDD-recommended reference for the assessment of iodine-deficiency disorders (IDD) in Malaysia.

Fulltext Obstructive retrosternal goitre mimicking severe bronchial asthma in pregnancy

Loo GH, Wan Mat WR, Muhammad R, Azman M

BMJ Case Rep, 2019 Aug 04;12(8).
PMID: 31383679 DOI: 10.1136/bcr-2019-229763

Acute airway obstruction in pregnancy remains a challenge to manage. Failure of appropriate and timely airway management may lead to maternal morbidity and mortality such as aspiration pneumonitis or worst hypoxaemic cardiopulmonary arrest. 1 As pregnancy may exacerbate asthma attacks, parturient presenting with wheezing or shortness of breath will commonly be treated as suffering from an asthmatic attack. 2 However, it is important to note other possible differential diagnoses. Thyroid disease is relatively common in women of childbearing age. The thyroid gland undergoes several changes during pregnancy, which may lead to altered function as well as gland enlargement and cause upper airway obstruction and symptoms similar to a bronchial asthma attack. 3 4 With that in mind, we report a case of a parturient with long-standing goitre in her second trimester who presented to our institution with acute respiratory symptoms and cardiopulmonary arrest.

Carcinoma in multinodular goitre

Koh KB, Chang KW

Br J Surg, 1992 Mar;79(3):266-7.
PMID: 1555099

A retrospective review of 107 patients operated on for multinodular goitre was carried out to determine the incidence of carcinoma. Of the group 7.5 per cent harboured incidental carcinomas with papillary carcinoma being the most common variety. The indications for removal of multinodular goitre should be compressive symptoms, suspicion of malignancy and cosmesis.

Effect of iodination of a village water-supply on goitre size and thyroid function

Maberly GF, Eastman CJ, Corcoran JM

Lancet, 1981 Dec 05;2(8258):1270-2.
PMID: 6118679

An iodinator was fitted to the existing gravity-fed water-supply of a remote village in Sarawak, Malaysia, where goitre was endemic. Within nine months, the prevalence of goitre had been reduced from 61% to 30%, with 79% of goitres showing visible reduction in size. All subjects were clinically euthyroid before and nine months after the start of iodination, although pre-treatment serum thyroid-stimulating hormone (TSH) concentrations varied from normal up to 24 mU/l. Before treatment basal serum triiodothyronine (T3) and thyroxine (T4) concentrations were typical of endemic goitre with a low mean serum T4 (80 +/- 30 [SD] nmol/l) and a slightly raised mean serum T3 (2.3 +/- 0.7 nmol/l). After iodination, circulating TSH concentration was generally undetectable (less than 0.1 mU/l), mean T3 concentration was unchanged, but the mean T4 rose significantly to 109 +/- 41 nmol/l (p less than 0.01). Urinary iodine concentrations fluctuated; this largely reflected intermittent blockage of the iodinator, but concentrations became consistent with a return to the iodine-replete state. There was no evidence of the Jod Basedow effect in the group studied. Iodinated water was more convenient to distribute than iodised salt and is less likely to cause Jod Basedow phenomenon than are injections of iodised oil. Moreover, iodination of water is effective in killing most microorganisms and this additional benefit could contribute significantly to village health.

Endemic goitre in Sarawak, Malaysia: I. Somatic growth and aetiology

Maberly GF, Eastman CJ

Southeast Asian J. Trop. Med. Public Health, 1976 Sep;7(3):434-42.
PMID: 1030847

A comparative epidemiological and anthropometric survey was conducted among Ibans, the largest indigenous ethnic group in Sarawak, in three regions where the endemicity of goitre exhibited marked differences , to assess the effect of endemic goitre on somatic growth. In the Ai river region the prevalence of goitre was 99.5%; 35% having grade 3 goitres, 55% grade 2 goitres and 9.5% grade 1 goitres. At Rubu the prevalence of endemic goitre was 74%; 3% having grade 3 goitre, 16% grade 2 goitre and 55% grade 1 goitre. In the Bajong region relatively few people were detected with goitre and most of these had migrated from other regions. Neurological cretinism was estimated at 3.6% in the severely goitrous Ai river population but was not detected in the other regions. Anthropometric data obtained from the three adult populations did not reveal any statistically significant differences in the following parameters: weight, height, weight/height ratio, height/sitting height ratios, head circumference, scapular skinfold thickness and left mid arm muscle circumference. The haemoglobin, serum total protein and serum albumin concentrations were similar in the three populations. It is concluded that endemic goitre occurs with a frequency of close to 100% in certain Iban populations which represents one of the highest incidences of endemic goitre in the world. Neurological cretinism is common in this population. Our observations suggest that body proportions and somatic growth do not vary among similar ethnic populations exhibiting greatly different endemicity of goitre. Although no iodine balance studies were performed, assessment of diets suggested that iodine deficiency is a significant contributory factor in the development of endemic goitre in Sarawak. Urgent attention to iodine supplementation is indicated to prevent the development of endemic goitre and neurological cretinism.

Fulltext Anesthesia for massive retrosternal goiter with severe intrathoracic tracheal narrowing: the challenges imposed -A case report-

Tan PC, Esa N

Korean J Anesthesiol, 2012 May;62(5):474-8.
PMID: 22679546 DOI: 10.4097/kjae.2012.62.5.474

Anesthetic management of patients with mediastinal masses remains challenging as acute cardiorespiratory decompensation may follow induction of anesthesia. We describe a 57 year old lady with massive retrosternal goiter and severe intrathoracic tracheal compression who had a total thyroidectomy. Comprehensive contingency plans were an essential prerequisite for successful management of difficult airway, including multidisciplinary involvement of otorhinolaryngologic and cardiothoracic surgeons preparing for rigid bronchoscopy and cardiopulmonary bypass. Awake oral fiberoptic intubation was performed under dexmedetomidine sedation. Severe tracheal narrowing necessitated usage of a 5.0 mm uncuffed flexometallic endotracheal tube. Anesthesia was maintained with sevoflurane and dexmedetomidine infusion with target controlled infusion of remifentanil as analgesia. No muscle relaxant was given. Surgical manipulation led to intermittent total tracheal compression and inadequate ventilation. The tumor was successfully removed via the cervical approach. A close working relationship between anesthesiologists and surgeons was the key to the safe use of anesthesia and uneventful recovery of this patient.

The most common cause of hyperthyroidism is Graves disease (GD) which is characterised by the presence of autoantibodies which binds to the TSH receptor (TRAb). Recently, a rapid, fully automated electrochemiluminescent immunoassay ElecsysAnti-TSHR for detection of autoantibodies to TSH receptor was made available for routine clinical use. The objective of this study is to evaluate this assay and to determine the sensitivity, specificity and cut-off value. Interassay and total imprecision (CV) were determined at 3.78-7.02 IU/L and 13.5-21.2 IU/L respectively. A total of 124 samples which comprised of 46 GD, seven Hashimoto thyroiditis (HD), 11 non autoimmune nodular goitre (NAG), 2 thyroid cancers (Ca) and 58 normal controls were retrospectively analysed to determine the sensitivity, specificity and cut-off value. Inter-assay CV’s were 2.4% at a concentration of 3.90 IU/L (range: 3.78-7.02 IU/l) and 0.8% at 20.80 IU/L (range:13.5-21.2 IU/l). Total imprecision was 3.8% at a concentration of 3.80 IU/L (range:13.5-21.2 IU/l) and 1.0% at 20.8 IU/L (range:13.5-21.2 IU/l). The ROC analysis of patients with GD, other thyroid disorders and normal controls revealed that the highest sensitivity (94%) and specificity (98%) were seen at cut-off value of 1.69 IU/L. Positive predictive value (PPV) and negative predictive value (NPV) was 95% and 94% respectively. At this derived cut-off value of 1.69 IU/L, we found that the sensitivity of TRAb positivity within the group of 29 newly diagnosed GD patients was 94%. Our results demonstrate that this fully automated assay with testing time of 27 minutes has high sensitivity in detecting GD and high specificity for discriminating other thyroid disease and represent major improvement in the diagnosis and management of patients with thyroid diseases.
