Graves’ disease and pregnancy

This section deals with the specificities of managing Graves’ disease during pregnancy. Graves’ disease incurs risks of fetal, neonatal and maternal complications that are rare but may be severe: fetal hyper- or hypothyroidism, usually first showing as fetal goiter, neonatal dysthyroidism, premature birth and pre-eclampsia. Treatment during pregnancy is based on antithyroid drugs alone, without association to levothyroxine. An history of Graves’ disease, whether treated radically or not, with persistent maternal anti-TSH-receptor antibodies must be well identified. Fetal monitoring should be initiated in a multidisciplinary framework that should be continued throughout pregnancy. Neonatal monitoring is also crucial if the mother still shows anti-TSH-receptor antibodies at end of pregnancy or underwent antithyroid treatment. The risk of recurrence of hyperthyroidism in the weeks following delivery requires maternal monitoring. The long-term neuropsychological progression of children of mothers with Graves’ disease is poorly known.     

Treatment of perianal fistula and abscess: Crohn’s and non-Crohn’s

Opinion statement The management of perianal abscesses and fistulas is relatively straightforward in most cases and based on a sound knowledge of the anatomy of the anorectum and adherence to established medical and surgical principles. Asymptomatic fistulas should not be treated, whereas abscesses require surgical drainage under general anesthesia. Fistula treatment includes drainage of any associated sepsis and eradication of the fistula track to prevent recurrence while preserving sphincter integrity. A small percentage of anal abscesses and fistulas are complex and very challenging to manage, particularly in conditions such as rectovaginal fistulas and abscesses and/or fistulas complicating Crohn’s disease. Treatment strategies in these situations rely on an accurate clinical assessment of the degree of rectal inflammation and perianal pathology. Treatment should combine aggressive medical therapy (antibiotics, immunomodulators, and anti-tumor necrosis factor antibody treatment) and minimal surgical interventions. Patients with proctitis have a significantly lower healing rate and a significantly higher complication rate with aggressive surgical interventions.     

Patients’ Beliefs and Preferences Regarding Doctors’ Medication Recommendations

Background An estimated 20–50% of patients do not take medications as recommended. Accepting a doctor’s recommendation is the first step in medication adherence, yet little is known about patients’ beliefs and preferences about how medications are prescribed. Objective To explore patients’ beliefs and preferences about medication prescribing to understand factors that might affect medication adherence. Methods Fifty members from 2 health plans in Massachusetts participated in in-depth telephone interviews. Participants listened to an audio-vignette of a doctor prescribing a medication to a patient and were asked a series of questions related to the vignette. Responses were reviewed in an iterative process to identify themes related to participants’ beliefs and preferences about medication prescribing. Results Participants’ beliefs and preferences about medication prescribing encompassed 3 major areas: patient–doctor relationships, outside influences, and professional expertise. Important findings included participants’ concerns about the pharmaceutical industry’s influence on doctors’ prescribing practices and beliefs that there is a clear “best” medication for most health problems. Conclusions Patients’ beliefs and preferences about medication prescribing may affect medication adherence. Additional empiric studies that explore whether doctors’ relationships with pharmaceutical representatives impact medication adherence by affecting trust are indicated. In addition, it would be worthwhile to explore whether discussions between patients and doctors regarding equipoise (no clear scientific evidence for 1 treatment choice over another) affect medication adherence.

Crohn’s and colitis in children and adolescents

Crohn’s disease and ulcerative colitis can be grouped as the inflammatory bowel diseases (IBD). These conditions have become increasingly common in recent years, including in children and young people. Although much is known about aspects of the pathogenesis of these diseases, the precise aetiology is not yet understood, and there remains no cure. Recent data has illustrated the importance of a number of genes-several of these are important in the onset of IBD in early life, including in infancy. Pain, diarrhoea and weight loss are typical symptoms of paediatric Crohn’s disease whereas bloody diarrhoea is more typical of colitis in children. However, atypical symptoms may occur in both conditions: these include isolated impairment of linear growth or presentation with extra-intestinal manifestations such as erythema nodosum. Growth and nutrition are commonly compromised at diagnosis in both Crohn’s disease and colitis. Consideration of possible IBD and completion of appropriate investigations are essential to ensure prompt diagnosis, thereby avoiding the consequences of diagnostic delay. Patterns of disease including location and progression of IBD in childhood differ substantially from adult-onset disease. Various treatment options are available for children and adolescents with IBD. Exclusive enteral nutrition plays a central role in the induction of remission of active Crohn’s disease. Medical and surgical therapies need to considered within the context of a growing and developing child. The overall management of these chronic conditions in children should include multi-disciplinary expertise, with focus upon maintaining control of gut inflammation, optimising nutrition, growth and quality of life, whilst preventing disease or treatment-related complications.     

Rifaximin and Crohn’s disease

In a recent article,Longman and Swaminath analyzed our paper on the use of rifaximin in patients with moderately active Crohn’s disease(CD).Here we report some considerations concerning their article.The exploratory post-hoc subgroup analysis showed that early-stage disease and,differently from that written by Longman and Swaminath,also colonic involvement seemed to be associated with a significant higher efficacy of rifaximin-EIR 800 mg twice daily.Early-stage disease is generally considered as the more easily treatable phase of CD,and the better response to rifaximin in Crohn’s colitis is in accordance with the high concentration of bacteria in the colon.In addition,patients with C reactive protein level>5 mg/L achieved remission more significantly than patients with normal values,thus suggesting that the symptoms were probably caused by inflammation instead of by non-inflammatory causes.We also analyze the role of rifaximin against gut bacteria and the clinical situations that could obtain the best results from antibiotics.     

Comparing ambulatory preceptors’ and students’ perceptions of educational planning

To compare ambulatory preceptors' and students' perceptions of the use of educational planning (setting goals, assessing needs, formulating objectives, choosing methods, and providing feedback and evaluation) in the office setting, we mailed a survey, which was returned by 127 longitudinal ambulatory preceptors and 168 first-year and second-year medical students. Faculty perceptions did not match student perceptions of what occurred in the longitudinal preceptor program teaching sessions in educational planning areas. Students perceived these activities were occurring with much less frequency than faculty perceived. Medical education needs to move beyond the usual faculty development workshop paradigm to a more comprehensive educational development model that includes training both faculty and students in core educational skills. This will enable the ambulatory setting to reach its full educational potential in training future physicians.     

Behçet’s disease and Chiari’s network

Behçet’s disease (BD) is a chronic, multisystemic, inflammatory process of uncertain origin. Diagnosis criteria consist of recurrent oral ulceration plus two of the following: genital ulceration, ocular and skin lesions, and positive pathergy test. Pulmonary embolism and, especially intracardiac thrombi, are very rare. We report the case of a patient with BD presenting with bilateral pulmonary embolism and intracardiac mass in right atrium.     

Behcet’s disease and IgA nephropathy

Although Beh?et’s disease (BD) is a kind of systemic disease, renal involvement is rare, especially IgA nephropathy (IgAN). Renal manifestations in BD range from mild urinary abnormalities to glomerulonephritis with persistent renal failure, which includes minimal change disease, proliferative glomerulonephritis, rapidly crescentic glomerulonephritis, renal amyloidosis and IgA nephropathy. Amyloidosis seems to be the most common type of renal lesion in BD, and several cases of nephrotic syndrome secondary to amyloidosis have been documented. Co-occurrence of BD and IgA nephropathy has only been reported in only few cases. We describe two patients with the rare association of BD and IgAN. We suggested that it is important to periodically perform renal function assessment in patients with BD, through urinalysis and measurement of serum creatinine for detecting any abnormality and providing an early adequate treatment.
