McKittrick-Wheelock syndrome presenting with presumed paraneoplastic syndrome extra-ocular muscle enlargement masquerading as thyroid eye disease.

Summary: Paraneoplastic syndromes (PS) are uncommon and are known to mimic other clinical entities, often carrying significant morbidity and mortality. The commonest cause of extra-ocular muscle enlargement (EOME) is thyroid eye disease (TED). Rarely, PS can cause EOME and masquerade as TED. We describe a 52-year-old female who presented with diarrhoea, acute kidney injury and electrolyte imbalance. An ophthalmic review identified right upper lid retraction. MRI orbits showed increased thickness of the inferior and medial recti bilaterally, presumed as TED. Whilst investigating her diarrhoea, imaging revealed a large rectosigmoid tumour which required surgical excision. In the context of electrolyte disturbance and acute kidney injury, a diagnosis of McKittrick-Wheelock syndrome (MWS) was made. Following successful surgery, electrolyte imbalance, diarrhoea and eyelid retraction improved. Repeat MRI orbits displayed complete resolution of EOME. To our knowledge, this is the first case of MWS presenting with PS-EOME masquerading as TED. Learning points: McKittrick-Wheelock syndrome (MWS) is a rare disorder, although likely under-recognised, which is characterised by diarrhoea, dehydration and electrolyte depletion that results from a hypersecretory colorectal neoplasm. Definitive treatment of MWS involves the resection of the colorectal neoplasm. Bilateral ophthalmopathy that appears to be Graves' ophthalmopathy on imaging, though clinical and biochemical evidence fails to identify a thyroid pathology, has been associated with malignancy on rare occasions. Such patients should be investigated for potential malignant causes of their ophthalmopathy.

Association between crural vessel patency and successful transmetatarsal amputation: a single centre experience.

BACKGROUND: Transmetatarsal amputation (TMA) has a reputation for failure, centred around wound breakdown. No study has looked at the direct association between the patency of individual crural arteries and the healing of TMA. TMA relies on a posterior skin flap which derives its blood supply from the posterior tibial (PT) artery. We investigated the association between PT patency and achievement of successful TMA. METHODS: A retrospective review of all patients undergoing TMA for complications of peripheral arterial occlusive disease in a regional vascular tertiary referral centre over a 9 year period (2006-2015). TMA was considered successful by the absence of a higher-level amputation. Follow-up was for a minimum of 12 months. RESULTS: 24 patients (21 male; mean age 64 years) were studied. TMA was successful in 16 (67%). On statistical analysis, successful TMA was not significantly associated with vessel patency in either superficial femoral artery (SFA), or any single or combination of named crural artery. CONCLUSION: TMA healing can be achieved in the absence of a patent posterior tibial artery. We support the role of TMA in selected patients, given its benefits compared to transtibial amputation.

How can positive and negative trainer feedback in the operating theatre impact a surgical trainee's confidence and well-being: a qualitative study in the north of England.

OBJECTIVE: To identify the perception of positive feedback (PF) and negative feedback (NF) provided by trainers in the operating theatre on surgical trainees' confidence and well-being. DESIGN: Narrative interview study. SETTING: Twelve hospitals that form part of one deanery within the UK. PARTICIPANTS: Maximum variation sampling of 15 higher general surgical trainees provided insight into how PF and NF from trainers in the operating theatre affect confidence and well-being. METHODS: Narrative telephone interviews were conducted with general surgical trainees between April and June 2016. All interviews were recorded, transcribed and anonymised. Transcriptions were analysed using the five-step framework analysis by two independent researchers. RESULTS: Fifteen trainees (age 28-38 years) were interviewed (median interview time: 29 min). Thematic framework analysis identified nine themes within the data. PF, which included corrective feedback, helped the trainees to relax and seemed to enhance their operative performance. All trainees reported significant and unjustified NF, some of which would be defined as undermining and bullying. Many believed this to have a negative impact on their training with minimal educational benefit. Many trainees felt NF adversely affected their performance in the operating theatre with some expressing a wish to leave the profession as a consequence. CONCLUSION: Both PF and NF exist in the operating theatre. Both have an important influence on the trainee, their performance and career. PF, if specific, helped aid progression of learning, increased motivation and performance of surgical trainees. In contrast, NF was perceived to have detrimental effects on trainees' performance and their well-being and, in some, introduced a desire to pursue an alternative career.

Outcomes in patients with indeterminate pulmonary nodules undergoing resection for colorectal liver metastases.

OBJECTIVES: This study aimed to assess outcomes in patients who underwent hepatic resection for colorectal liver metastases (CRLM) with subcentimetre indeterminate pulmonary nodules (IPN) and to devise a management pathway for these patients. METHODS: Patients undergoing CRLM resection from January 2006 to December 2010 were included. Survival differences following liver resection in patients with and without IPN were determined. RESULTS: A total of 184 patients were included, 30 of whom had IPN. There were no significant differences between the IPN and non-IPN groups in terms of demographics, surgery and pathological factors. There were no significant differences between patients with and without IPN with respect to disease-free (P= 0.190) and overall (P= 0.710) survival. Fifteen patients with IPN progressed to metastatic lung disease over a median period of 10 months (range: 3-18 months); six of these patients underwent lung resection. Of the remaining 15 patients with IPN, eight showed no IPN progression and subsequent CT scans did not identify IPN in the remaining seven. CONCLUSIONS: Colorectal liver metastases patients with IPN who have resectable disease should be treated with liver resection and should be subject to intensive surveillance post-resection. Although 50% of these patients will progress to develop lung metastases, this does not appear to influence survival following liver resection.
