Other features are opthalmopathy, and acropachy. It is an IgG antibody mediated. Grave’s disease is one of the indications for thyroidectomy; the study reviewed our 3 year experience in the management of patients with the disease. Patients and Methods: We reviewed all patients with Diffused toxic goiter (Grave’s disease) managed in the University of Maiduguri Teaching Hospital (UMTH) between January 2010 and December 2014. Patients with emergency presentation (thyrocardia) were resuscitated and optimized. All patients were rendered euthyroid with carbimazole and propranolol on outpatient basis. Subtotal thyroidectomy under general anesthesia was done in all patients. Results: A total of 85 patients were analyzed, 78 were females and 7 males with a female to male ratio of 11.14: 1. Age ranged from 14 – 70 years with a mean of 31.84 years and SD of 10.89, mean age for females, and males were 31.74, and 32.86 respectively. The peak age group was 20 – 29 accounting for 41.18%, and 78.82% of the patients were under the age of 40 years. The presenting clinical features were anterior neck swelling, heat intolerance, and hair loss/darkening of skin in all patients. Associated autoimmune diseases were type 1 diabetic mellitus in 5.88%, Rheumatoid arthritis in 3.53%, and systemic lupus erythromatosis (SLE) in 1.18%. Postoperative complications were respiratory obstruction in 11.76%, and transient hypocalcaemia in 10.59%. Conclusion: Grave’s disease is common, with spectrum of manifestations characterized by goiter, thyrotoxicosis, and psychosocial problems. Subtotal thyroidectomy is still a viable option in developing countries. IJOART KEYWARDS: Diffused Toxic Goiter, Psychosocial Thyroidectomy, Outcome of Management.

It is a syndrome comprising hyperthyroidism with a diffuse goiter, eye disease characterized by inflammation and involvement of intra orbital structures, dermopathy refer to as pretibial myxedema, and rare involvement of the nails, fingers and long bones known as acropachy. Prior to Graves’ description the Greek philosopher Aristotle and the English physician Caleb Parry had described the condition 1. The disease is the most common autoimmune disease representing 50-80% of cases of hyperthyroidism in the U.S.A2 it occurs more commonly among women, smokers, and patients with other autoimmune diseases or a family history of thyroid autoimmunity3. The emergence of this autoimmune process is probably due to an underlying genetic susceptibility with superimposed environmental factors particularly HLA alleles on chromosome 6 namely HLA- DRB1-08, DRB3-0202, and HLA-DQA1-0501 are known to confer an increased risk of Graves’ disease4-5. There is always a trigger before the onset of clinical features. Such triggers include stressful life events, infection, job loss, or bereavement, exposure to high doses of iodine, and recent child birth. The clinical features include weight loss despite increase appetite, heat intolerance, irritability, insomnia, sweatiness, diarrhea, palpitations, muscular weakness, and menstrual irregularity. Others are diffused goiter, fine resting tremor, tachycardia, hypereflexia, eyelid lag, worm smooth skin, and proximal myopathy. Rarely atrial fibrillation and thyroid bruit reflecting increased thyroid vascularity. Older patients are more likely to present with depression, weight loss, and cardiovascular features like congestive cardiac failure than younger patients6. This hyper dynamic congestive cardiac failure is also called thyrocardia. Women may presents for cosmetic reasons, with concerns about goiter, eye changes, or hair loss7-8. These cosmetic problems were under reported, especially in developing countries where gender inequality, cultural factors, poor socioeconomic status and low level of education put women at disadvantage. Most women are dependent on men therefore loss of self esteem and body image lead many women that are not gainfully employed in to depression and suicidal tendency, marital separation, divorce and instability are common among women with Graves’ disease. Total thyroidectomy with thyroxine replacement is currently the gold standard in goiter surgery for both benign and IJOART Copyright © 2015 SciResPub. IJOART International Journal of Advancements in Research & Technology, Volume 4, Issue 3, April -2015 ISSN 2278-7763 4 malignant conditions9-10. Many developing countries have a peculiar problem of non availability of thyroxine and where available is too expensive and unaffordable to be taken for life. This is a strong indication for subtotal thyroidectomy in our environment. The study reviewed our experience in Graves’ disease management. IJOART Copyright © 2015 SciResPub. IJOART International Journal of Advancements in Research & Technology, Volume 4, Issue 3, April -2015 ISSN 2278-7763 5 Patients and Methods: The study reviewed all patients with Diffused toxic goiter (Grave’s disease) managed in the University of Maiduguri Teaching Hospital (UMTH) between January 2010 and December 2014. Permission for the study was granted by the Hospital Ethical and Research Committee. Written informed consent was obtained from the patients. Information was extracted from clinical and laboratory records and data analyzed using SPSS version 16. The diagnosis was made from clinical and laboratory evaluation. Investigations done were Thyroid function test (T3, T4, and TSH), urinalysis, full blood count, blood chemistry, indirect laryngoscopy, electrocardiography, and echo cardiography where necessary. Patients with emergency presentation (thyrocardia) were resuscitated and optimized, and patients were rendered euthyroid with carbimazole and propranolol on outpatient basis before surgery. All patients had subtotal thyroidectomy under general anesthesia with endotracheal intubation. Prophylactic antibiotic (ceftriaxone) was given at induction. Patients were monitored postoperatively and followed up after discharge. IJOART Copyright © 2015 SciResPub.

Age ranged from 14 – 70 years with a mean of 31.84 years and SD of 10.89, mean age for females, and males were 31.74, and 32.86 respectively. The peak age group was 20 – 29 accounting for 35 (41.18%), and 67 (78.82%) of the patients were under the age of 40 years table 1. The presenting clinical features were anterior neck swelling, heat intolerance, and hair loss/darkening of skin in all patients table 2. Co-morbid medical conditions were hypertension in 11 (12.94%), type one diabetic mellitus in 5 (5.88%), Rheumatoid arthritis in 3 (3.53%), asthma in 2 (2.35%), and systemic lupus erythromatosis (SLE) in 1 (1.18%). Histology confirmed Graves’ disease in all patients with associated nodules in 11 (12.94%) no malignancy was found. Postoperative complications were respiratory obstruction in 10 (11.76%), comprising of laryngeal edema in 6 (7.06%), recurrent laryngeal nerve palsy in 1 (1.18%), and hematoma in 3 (3.53%). Others were transient hypocalcaemia in 9 (10.59%), recurrence in 2 (2.35%) (Who subsequently had total thyroidectomy with thyroxine replacement for life), and keloid/hypertrophic scar in7 (8.24%). There was no mortality. The mean hospital stay, and duration of follow up were 5 days, and 27 months. IJOART Copyright © 2015 SciResPub. IJOART International Journal of Advancements in Research & Technology, Volume 4, Issue 3, April -2015 ISSN 2278-7763 7 Discussion: The study revealed the mean age for Graves’ disease to be 31.84 years, and the patient’s age ranged from 14 – 70 years. This indicates by far Graves’ disease is the disease of the young in this environment compared to similar study by Jolanta et al11 that found older patients with the mean age of 47.12years, and age range of 18 – 84 years. Similarly the mean ages for males and females of 32.86years and 31.74years respectively were lower than their findings. Globally however there is a rising incidence of Graves’ disease among children especially in the Far East12. The traditionally recognized clinical features 13 of Graves’ disease were similar to our findings. However this study revealed the depth of psychosocial disturbance associated with Graves’ disease as evidence by the findings of hostile/quarrelsome disposition, and domestic problems of separation or divorce in 85.88%, and 27.06% respectively. Graves’ disease patients are found to have low self esteem and body image due to associated poor cosmetic outlook (hair loss, goiter, extholpthalmus, and dermopathy) in (91.76%). The fore going psychosocial problems constitute a major part of the unreported features of Graves’ disease that the current study found. Graves’ disease is known to be associated with other autoimmune disorders like myasthenia gravis, type 1 diabetes mellitus 14-15. The current study found type 1 diabetes mellitus, and rheumatoid arthritis. The histology revealed Graves’ disease in all patients with nodules in 12.94% however there was no incidental carcinoma in variance with study by Mishra et al16that found incidental carcinoma in their series. The postoperative complications in our series were respiratory obstruction in 11.76% (from hematoma 3.53%, laryngeal edema 7.06%, and recurrent laryngeal nerve palsy 1.18%), and transient hypocalcaemia in 10.59%. These complications were similar to complications of subtotal thyroidectomy but lower than found in total thyroidectomy as reported in comparative study of total versus subtotal thyroidectomy by Colak et al17. Globally there is a reduction in the complications associated with thyroidectomy, therefore the reluctance to recommend thyroidectomy for definitive treatment of Graves’ disease has been challenged in recent years. A study by Pearce et al18 showed that thyroidectomy is more cost effective than either radio iodine ablation or antithyroid medication and offers patient a better quality of life. The argument today is which surgery is the best? Total thyroidectomy on the one hand, and near total or subtotal IJOART Copyright © 2015 SciResPub. IJOART International Journal of Advancements in Research & Technology, Volume 4, Issue 3, April -2015 ISSN 2278-7763 8 thyroidectomy on the other hand based on variation in complications 19-21. The current study had 2.35% recurrent goiter that were offered completion thyroidectomy. Alessandro et al22 in a 20 year follow up period found a recurrence of 2-70% of cases, and advocated for total thyroidectomy at the initial surgery because surgical treatment of such recurrence is associated with higher complications.
