Charcot-Marie-Tooth neuropathy type 1A combined with Duchenne muscular dystrophy

We report a 24-year-old male with an unusual combination of two inherited neuromuscular disorders – Charcot-Marie-Tooth (CMT) disease type 1A and Duchenne muscular dystrophy (DMD). A phenotypic presentation of this patient included features of both these disorders. Nerve conduction studies revealed demyelinating peripheral neuropathy. Electromyography showed a profound myogenic pattern. The serum creatine kinase level was highly elevated. Muscle biopsy revealed a dystrophic picture with deficient dystrophin immunostaining. CMT1A duplication on chromosome 17p11.2 was found. The frame-shift mutation c.3609–3612delTAAAinsCTT (p.K1204LfsX11) was detected in the dystrophin gene by analysing mRNA isolated from the muscle tissue. The patient inherited both these mutations from his mother. The combination of CMT1A and DMD has not been reported as yet.     

Gun shot wound neck

All penetrating neck wounds are potentially very dangerous and require emergency treatment. The choice of treatment for the stable patient remains controversial, a number of studies encouraging mandatory surgical exploration and a similar number encourage selective surgical exploration. Knowledge of the physical properties of the penetrating object or weapon can help to determine a treatment plan and predict the risk of injury- All tracheal and esophageal injuries with structural damage should be repaired primarily. A case of Gun Shot Wound Neck was air evacuated to Army Hospital R & R Delhi Cantt in a tracheostomised state. Patient was evaluated in detail, he had trachea esophageal fistula. The management of this case is discussed along with principles of management of war injuries.     

Which constructs can predict emotional exhaustion in a working population? A study into its determinants

The main objective of this study was to examine the psychosocial stress model developed by Taylor and Aspinwall with emotional exhaustion as the outcome variable. Respondents, 409 men and 346 women, who had a paid job for at least 20 hours per week, completed questionnaires concerning demographic variables, personality, temperament, work pressure, workload, perceived social support, appraisal, coping, and emotional exhaustion. Structural equation analyses provided only partial support for the validity of the model. First, on theoretical and statistical grounds, one more path linking external resources to social support was added. Second, contrary to expectations, coping styles did not predict emotional exhaustion. To conclude, when coping is measured retrospectively, it does not add to our understanding of emotional exhaustion. It is suggested that future studies should be longitudinal and include objective measures of stressors and psychosocial health outcomes in addition to self‐reports.

PR35THE INCIDENCE OF NON‐MELANOMA SKIN CANCER IN NEW ZEALAND

Background It is estimated that skin cancers cost $33 million per annum to the New Zealand healthcare system. Basal cell carcinoma and squamous cell carcinoma are the commonest types of non melanoma skin cancers (NMSCs). Anecdotal evidence indicates that there has been a doubling in the incidence of NMSCs in New Zealand over the last decade. Because of the high incidence mandatory reporting of NMSCs to the National Cancer Registry is not required. This lack of accurate data has led to poor health care policies and strategies including funding and workforce planning. Aims The aims of this study are to (1) present the latest statistics on NMSCs in New Zealand, including the incidence across different regions over the last decade, patient demographics, anatomic distribution of NMSCs, incidence and sites of metastasis, and disease‐specific survival; to (2) the histopathology of NMSCs, including surgical margins, histologic grade, and perineural, lymphatic, and vascular invasion; and (3) the relative role of different faculties treating NMSCs. Method This project has been approved by the multi‐centre ethics committee. A retrospective review was conducted from patients’ histology records from public and private pathology laboratories within defined catchment areas. Criterion for analysis is a confirmed diagnosis of NMSC treated surgically. A Microsoft Access database is created that will facilitate subsequent data retrieval and analysis. Results and Conclusion It is hoped that this up‐to‐date data will form the framework for the development of sound and sustainable healthcare policies of management of NMSCs including management strategies and workforce planning, and research direction on this common disease.     

Individualized Mycophenolate Mofetil Dosing Based on Drug Exposure Significantly Improves Patient Outcomes After Renal Transplantation

Efficacy and safety of mycophenolate mofetil (MMF) may be optimized with individualized doses based on therapeutic monitoring of its active metabolite, mycophenolic acid (MPA). In this 12-month study, 137 renal allograft recipients from 11 French centers receiving basiliximab, cyclosporine A, MMF and corticosteroids were randomized to receive either concentration-controlled doses or fixed-dose MMF. A novel Bayesian estimator of MPA AUC based on three-point sampling was used to individualize doses on posttransplant days 7 and 14 and months 1, 3 and 6. The primary endpoint was treatment failure (death, graft loss, acute rejection and MMF discontinuation). Data from 65 patients/group were analyzed. At month 12, the concentration-controlled group had fewer treatment failures (p = 0.03) and acute rejection episodes (p = 0.01) with no differences in adverse event frequency. The MMF dose was higher in the concentration-controlled group at day 14 (p < 0.0001), month 1 (p < 0.0001) and month 3 (p < 0.01), as were median AUCs on day 14 (33.7 vs. 27.1 mg*h/L; p = 0.0001) and at month 1 (45.0 vs. 30.9 mg*h/L; p < 0.0001). Therapeutic MPA monitoring using a limited sampling strategy can reduce the risk of treatment failure and acute rejection in renal allograft recipients 12 months posttransplant with no increase in adverse events.     

Endovascular treatment (EVT) of acute traumatic lesions of the descending thoracic aorta--7 years' experience.

OBJECTIVES: To present a single centers' 7-year experience in the endovascular treatment of acute traumatic lesions of the descending thoracic aorta (ATL of the DTA). MATERIALS & METHODS: Between March 1999 and December 2006, 34 consecutive acute traumatic lesions of the descending aorta (23 men, mean age 44 years) were treated endovascularly. Stentgrafts used were TAG Excluder, Zenith TX2 and Talent. In 23 patients the Left Subclavian Artery (LSA) was covered. Mean procedural duration was 20 to 75 minutes. RESULTS: Exclusion of the rupture site was achieved in all cases with no conversion to open surgery. Overall 30-day mortality was 8.8%. Two patients died on post operative day (pod) 1 and one on pod 22 from cranial injuries. No death or neurological deficit related to the endovascular treatment was reported. Four type I endoleaks required treatment either by balloon reexpansion (n=2) or by additional stentgraft implantation (n=2). In two patients the stentgraft collapsed totally several days postoperatively. Two patients required secondary surgical procedures (iliac access complication and revascularisation of the left subclavian artery n=1). The average follow-up was 43.8 months (1-93 months). No stentgraft related abnormality has been subsequently documented. CONCLUSIONS: The endovascular treatment of ATL of the DTA may offer the best means of therapy in a polytrauma patient.     

Perforation of a retrocaecal appendix presenting clinically as a right lumbar abscess.

Presentations of acute appendicitis represent an ongoing challenge to surgeons. This case of retrocaecal perforated appendicitis presented clinically as a right lumbar abscess, with the concomitant new diagnosis of type 2 diabetes mellitus in a 66-year-old male. This case emphasises the importance of an abdominal CT scan in any patient presenting with unusual sepsis near the abdomen.
