Management of Primary Hyperparathyroidism: Past purchase 15mg primaquine free shipping, Present and Future 167 Surgery is the only order primaquine 15 mg fast delivery, definitive treatment for symptomatic disease primaquine 15mg without prescription. Since majority of cases of primary hyperparathyroidism, are due to a single parathyroid adenoma, selective gland excision is a better option. This should be facilitated with appropriate preoperative localization techniques such as with (Tc99m) sestamibi scanning alone or combined with other modalities wherever possible. Intra-operative parathyroid hormonal monitoring may be a useful adjunct and can predict possibility of multigland disease and the need for converting the procedure to a bilateral neck exploration. Minimally access parathyroid surgery is feasible and should probably be increasingly offered to select group of patients. Conversion to bilateral neck exploration should not be regarded as a complication. The final statement is that: the success of both conventional and minimal access parathyroidectomy is dependent on the surgeons hard earned experience and nothing can substitute that.

Indian Journal of Surgery 72:2, 135-137 12 Treatment Modalities in Thyroid Dysfunction R. Introduction Thyroid dysfunction is a common condition mainly affecting women, with a male to female ratio of around 1:10. An organ-specific autoimmune response is the underlying cause in the majority and susceptibility to thyroid autoimmunity is believed to be influenced by an interaction between genetic predisposition and environmental factors, in addition to endogenous factors such as age and sex (Vanderpump 1995). These antibodies do not seem to have a direct functional role but are implicated in perpetuating the intrathyroidal inflammation and tissue destruction (Ajjan & Weetman 2008). It is frequently seen in multiple family members indicating a genetic predisposition, commonly seen in organ-specific autoimmune conditions. The second commonest cause is a solitary toxic nodule or multinodular goitre accounting for 15-20% of cases (Orgiazzi & Mornex1990). Toxic multinodular goitres tend to occur insidiously in elderly patients with a longstanding nodular goitre. Toxic adenomas result from benign monoclonal proliferation producing a single autonomously functioning nodule, typically greater than 2. Goitres of any nature are more prevalent in iodine deficient areas and are more common in females (Reinwein et al 1988). There are other rare causes for hyperthyroidism, which should be kept in mind when assessing the patient and these are summarised in Table 1. Careful history and examination will typically point towards a diagnosis of hyperthyroidism and its underlying cause. Biochemical confirmation is required and enables the clinician to monitor response to treatment. In some cases, the cause of hyperthyroidism is unclear and additional biochemical and/or imaging tests may be needed. The presence of thyroid autoantibodies supports the diagnosis of thyroid autoimmunity. A solitary nodule with increased uptake and suppressed function in the remaining, normal tissue is seen in a toxic adenoma (Cooper 2003). They should generally be instituted in patients with a confirmed diagnosis of hyperthyroidism, but may not be necessary if definitive treatment is planned early and hyperthyroidism is mild (Weetman 2000). The thionamides act by inhibiting the formation and coupling of these iodotyrosine residues and thus reduce T4 and T3 concentrations. Propylthiouracil also has the action of inhibiting the peripheral conversion of T4 to T3. Carbimazole is usually commenced at a dose of 20-40mg once a day, depending on the severity of thyrotoxicosis. A drop in the T4 to low-normal levels or below the normal range indicates that a reduction in dosage or addition of levothyroxine is needed. The former scenario constitutes the titration regime, whereas the latter is known as block and replace regime. In the titration regime, the smallest dose of anti-thyroid drug is used to maintain thyroid function within the normal range.
