Application and impact assessment of an interactive journal club format among endocrinology fellows-in-training in a tertiary hospital academic center: a case study

Background: The interactive journal club is designed to utilize a new approach in appraising research in order to maximize the benefits of the traditional journal club. In this new approach, the participants are actively involved in a structured process of critical data appraisal rather than just being passive listeners. In this case study, we applied the interactive journal club format and assessed its impact among our endocrinology fellows-in-training. Methods: We conducted four interactive journal club sessions within a four-week span, one per each week via a virtual platform. The 12 participants were the same throughout all sessions. Each session was recorded following informed consent. At the end of all sessions, feedback was obtained, tabulated and compared. Results: Sessions lasted from 59 to 83 minutes (mean, 67.75 minutes). Participants became more active and spontaneous as the sessions progressed. All participants found the format more fun and proactive. This approach allowed more critical thinking and processing of information. Salient features include increased self-esteem and confidence, additional learning from other participants, better retention of information, and utilization in future practice. Conclusions: Traditional approaches are transformed from passive presentations of recent developments in medicine into an interactive discussion while allowing the retention of the spirit and essence of a traditional journal club, as well as exploring new and improved approaches in clinical training and education.

Challenges and unmet needs in basal insulin therapy: lessons from the Asian experience

Basal insulin therapy can improve glycemic control in people with type 2 diabetes. However, timely initiation, optimal titration, and proper adherence to prescribed basal insulin regimens are necessary to achieve optimal glycemic control. Even so, glycemic control may remain suboptimal in a significant proportion of patients. Unique circumstances in Asia (eg, limited resources, management of diabetes primarily in nonspecialist settings, and patient populations that are predominantly less educated) coupled with the limitations of current basal insulin options (eg, risk of hypoglycemia and dosing time inflexibility) amplify the challenge of optimal basal insulin therapy in Asia. Significant progress has been made with long-acting insulin analogs (insulin glargine 100 units/mL and insulin detemir), which provide longer coverage and less risk of hypoglycemia over intermediate-acting insulin (Neutral Protamine Hagedorn insulin). Furthermore, recent clinical evidence suggests that newer long-acting insulin analogs, new insulin glargine 300 units/mL and insulin degludec, may address some of the unmet needs of current basal insulin options in terms of risk of hypoglycemia and dosing time inflexibility. Nevertheless, more can be done to overcome barriers to basal insulin therapy in Asia, through educating both patients and physicians, developing better patient support models, and improving accessibility to long-acting insulin analogs. In this study, we highlight the unique challenges associated with basal insulin therapy in Asia and, where possible, propose strategies to address the unmet needs by drawing on clinical experiences and perspectives in Asia.

Acute mania after levothyroxine replacement for hypothyroid-induced heart block

Psychiatric disturbances can manifest after levothyroxine (LT4) treatment for severe hypothyroidism. We present the case of a young Filipino man with Hashimoto's thyroiditis and high-grade heart block, who was given a full replacement LT4 dose on admission. Twenty-four hours after this dose, he developed manic symptoms, which were addressed with sedatives and neuroleptics with gradual restoration of euthymia the following day. A comprehensive workup did not reveal any findings suggestive of another aetiology for either mania or heart block. We ultimately ascribed the mania as secondary to LT4, and the heart block to hypothyroidism. Although mania is more likely to be precipitated by high starting LT4 doses, reports have shown that symptoms can still arise even at lower doses and with more gradual titration, especially in long-standing hypothyroidism.

A comparison of the accuracy of clinical decisions based on full-text articles and on journal abstracts alone: a study among residents in a tertiary care hospital

BACKGROUND

Many clinicians depend solely on journal abstracts to guide clinical decisions.

OBJECTIVES

This study aims to determine if there are differences in the accuracy of responses to simulated cases between resident physicians provided with an abstract only and those with full-text articles. It also attempts to describe their information-seeking behaviour.

METHODS

Seventy-seven resident physicians from four specialty departments of a tertiary care hospital completed a paper-based questionnaire with clinical simulation cases, then randomly assigned to two intervention groups-access to abstracts-only and access to both abstracts and full-text. While having access to medical literature, they completed an online version of the same questionnaire.

FINDINGS

The average improvement across departments was not significantly different between the abstracts-only group and the full-text group (p=0.44), but when accounting for an interaction between intervention and department, the effect was significant (p=0.049) with improvement greater with full-text in the surgery department. Overall, the accuracy of responses was greater after the provision of either abstracts-only or full-text (p<0.0001). Although some residents indicated that 'accumulated knowledge' was sufficient to respond to the patient management questions, in most instances (83% of cases) they still sought medical literature.

CONCLUSIONS

Our findings support studies that doctors will use evidence when convenient and current evidence improved clinical decisions. The accuracy of decisions improved after the provision of evidence. Clinical decisions guided by full-text articles were more accurate than those guided by abstracts alone, but the results seem to be driven by a significant difference in one department.

Thyroid cancer in Plummer's disease

Thyroid cancer with concomitant hyperthyroidism is rare. Most foci of malignancy are small and seen postoperatively as incidental findings after surgery for hyperthyroidism. Thyroid masses with clinical features of malignancy and concomitant hyperthyroidism are less-commonly reported. We report two cases of multinodular toxic goitre or Plummer's disease with clinical features of malignancy. Both patients had large multinodular goitres with evidence of metastasis to the manubrium for the first patient and to the lymph node and lungs for the second patient. Both were clinically euthyroid but with free hormone excess and suppressed thyroid stimulating hormone (TSH) on laboratory testing. Both patients received methimazole prior to thyroidectomy. Histopathology revealed follicular variant of papillary cancer with metastasis to the manubrium for the first patient and follicular thyroid cancer with lymph node metastasis for the second. While rare, thyrotoxicosis can occur with malignancy, Plummer's disease may harbour cancer and behave aggressively.

Sweet's syndrome associated with Hashimoto's thyroiditis

Sweet's syndrome or acute febrile neutrophilic dermatosis is characterised by the abrupt onset of painful erythematous plaques or nodules, pyrexia (>38°F) and histopathologic evidence of a dense neutrophilic infiltrate without vasculitis. It has been reported in association with many diseases, however, its association with Hashimoto's thyroiditis is rare. A 47-year-old Filipino woman with a 30-year history of an asymptomatic anterior neck mass developed painful, erythematous annular plaques on her arms with associated fever. Skin biopsy confirmed the diagnosis of Sweet's syndrome. The anterior neck mass was confirmed to be Hashimoto's thyroiditis. This is a rare association with only two reported cases in the literature. There are no published cases in the Philippines on Sweet's syndrome and Hashimoto's thyroiditis to date.

Cushing's syndrome in pregnancy

A 22-year-old G(1)P(0) was admitted at 26 weeks gestation for preeclampsia, hyperglycaemia and cushingoid features. Elevated 24-h urine free cortisol (UFC) and suppressed plasma adrenocorticotrophic hormone (ACTH) suggested ACTH-independent Cushing's syndrome. Ultrasound showed left adrenal mass. She delivered preterm at 28 weeks due to severe preeclampsia and fetal distress. The infant expired after 4 days. Blood pressure was controlled after delivery and the patient was discharged on ketoconazole. Adrenalectomy was planned postpartum; however, she withdrew consent and was lost to follow-up. A 33-year-old G(1)P(1) presented with gestational diabetes. Pregnancy was complicated by premature delivery at 31 weeks for fetal distress. The baby improved and survived. Three months postpartum, she was evaluated for osteoporosis after sustaining a fracture from a fall. Cushingoid facies, elevated 24-h UFC, suppressed ACTH and a right adrenal mass on MRI confirmed an ACTH-independent Cushing's syndrome. She underwent adrenalectomy and improved.
