Short message service as a tool to improve perioperative follow-up of surgical outpatients: A before-after study.

BACKGROUND: In outpatient surgery, the patients may be called by phone for detecting and managing perioperative problems. However, phone calls consume time and can waste caregiver's time when the patient is not available. Information and communication technologies could bridge the gap between available resources and need to contact patients. METHODS: In the present before-after study, the before-implementation group was contacted by phone (phone group). The after group was contacted with a SMS or a phone call according to patient's preference (SMS group). The primary outcome was the non-inferiority of the SMS system on the occurrence of preoperative events disturbing the organisation of unit including cancellation of the case related to patient's condition the day before and the day of surgery; non-compliance with fasting rules or requirement of an escort; non-adherence to instructions regarding medication; not reporting to the surgical centre, or a delayed arrival > 30 min. RESULTS: Among 1300 included outpatients (650 per group), 381 (59%) and 542 (83%) patients were successfully contacted in the preoperative period in phone or SMS group, respectively P < 0.0001). Preoperative events were observed in 94 patients of the phone group (14.5% [CI 95% 11.9-17.3]) and in 77 patients of the SMS group (11.8% [CI 95% 9.5-14.6]), meaning that the upper bound 95% CI of the group was within the non-inferiority margin. CONCLUSIONS: In outpatient surgery, implementation of an SMS-based system, supplemented by phone calls for contacting patients is not inferior to a phone-based system in regard to preoperative events.

[Treatment of HIV facial lipoatrophy with a submalar porous polyethylene implant (Medpor)]. / Traitement des lipoatrophies faciales utilisant des implants de Medpor en polyéthylène poreux.

Human immunodeficiency virus associated facial lipoatrophy is becoming epidemic and is a distressing sign for patients. Non permanent fillers provide only temporary results and cannot be the solution for severe cases. Lipodystrophy makes the lipofilling difficult to perform with a fibrous low quality fat difficult to harvest. We propose another solution using porous polyethylene implants (Medpor). Eight patients underwent submalar augmentation through an upper gingivobuccal sulcus incision that allows a subperiosteal dissection. The implants are carved to provide the desired augmentation. Overall, eight patients had good or very good aesthetic postoperative outcomes as determined by the patient and the surgeon. No complications occurred and results remain natural. Porous polyethylene implant (Medpor) is our treatment of choice for mild to severe facial lipoatrophy. Besides these implants could be removed easily later if needed.

[Can one propose aesthetic surgery to one male or female patient with an hereditary angio-oedema?]. / Peut-on proposer un acte de chirurgie esthétique à un(e) patient(e) atteint(e) d'un oedème angioneurotique?

The hereditary angio-oedema (HAE) is a rare disease characterised by the occurrence of spontaneous or secondary, subcutaneous and submucosal swellings within any part of the body and especially in the upper respiratory tract. Surgery, due to the stress and the oro-tracheal intubation is a high risk situation for severe attack occurrence that may engage the patient life. This explains reluctance for surgeons and anesthesiologists to perform surgical operations in these patients. We think that efficiency of the prophylaxis and the emergency care for acute attacks can allow them to propose to these patients, plastic and aesthetic surgery in optimal security conditions. Androgens represent the main part of HAE prophylaxis treatment but usually cause masculinization in the females. We report this case of a woman, affected by HAE, treated by danazol: Danatrol for long-term prophylaxis who developed a mammary hypotrophy for which she was desirous to correct with breast implant. This surgery provided good morphological results without complication and was enabled to increase the observance of the prophylaxis treatment. Through this case report we lend a practical view of the surgery management of these patients affected by hereditary angio-oedema.

Esophageal stent migration: Testing few hypothesis with a simplified mathematical model.

Esophageal stent placement has significantly improved the quality of life in patients with malignant as well as benign esophageal obstructing lesions. Despite its early success and rapid adoption, stent migration still occurs in as many as 30% of cases especially with fully covered stents. To date, few models of interaction between the stent and the esophageal wall have been published and these have only focused on the deployment of the stent or the static mechanical stress distribution of the stent material. To elucidate the mechanism behind esophageal stent migration we developed a simplified radially symmetric computational model of esophageal peristalsis and the stent. A thorough review of the literature on esophageal peristalsis was performed and pertinent data were implemented into the model. Similarly, mechanical properties of an existing esophageal stent were used for the stent model. A sensitivity analysis of the parameters of the model enabled identification of the key elements of stent design that influence the degree of stent migration including flares design, stent length as well as longitudinal and radial stiffness. A comparison of the model to the migration rate reported in clinical studies for various types of fully covered stents further verified our model, which can significantly contribute to the development of a more stable esophageal stent with lower rates of migration.

Use of ultrasonic dissection in the early surgical management of periorbital haemangiomas.

PURPOSE: To evaluate the efficacy and safety of the early surgical excision of periorbital haemangiomas with an ultrasonic scalpel in infants at risk of visual impairment. STUDY: A retrospective analysis of 67 infants diagnosed to be at risk of amblyopia from periorbital haemangiomas, treated consecutively with the Dissectron between 1994 and 2005. Ophthalmic outcome parameters included the pre- and postoperative measurement of visual axis occlusion, strabismus, astigmatism, and degree of amblyopia. RESULTS: Visual performance showed an overall improvement of 30% following treatment. Seventy-six patients were found to have abnormal ophthalmic examinations preoperatively, compared to 46 following surgery. After surgery, visual axis occlusion decreased from 73 to 6%; amblyopia decreased from 67 to 22%, strabismus decreased from 26 to 18% and astigmatism (>onedioptre) decreased from 66 to 31%. Mean astigmatism values decreased from 3.5 to 1.9 dioptres. No new cases of astigmatism, strabismus or amblyopia were diagnosed postoperatively. Three minor complications resolved with conservative treatment. All patients were satisfied with the outcome of their surgery. CONCLUSION: Early surgical excision of periorbital haemangiomas using the Dissectron in infants with an established risk of visual impairment is a safe and effective alternative to pharmacological therapy. The use of the Dissectron is associated with reduced operative times and a shorter hospital stay.

Necrotizing fasciitis during de novo minimal change nephrotic syndrome in a kidney transplant recipient.

Skin infections and particularly necrotizing fasciitis (NF) represent a rare but serious complication after transplantation. Optimal management depends on prompt diagnosis with identification of the causative organisms to allow appropriate antibiotic therapy in association with surgical debridement. We report a case of a methicillin-resistant Staphylococcus aureus (MRSA) NF as the single pathogen in a renal transplant recipient, during the course of a de novo minimal-change nephrotic syndrome, treated with high-dose steroids. Antibiotic therapy together with surgical debridement and discontinuation of immunosuppressive treatment led to a complete recovery, despite persistence of the nephrotic syndrome. The development of de novo minimal-change nephrotic syndrome after renal allograft transplantation should alert physicians to the possibility of MRSA NF during an increase in the immunosuppressive regimen.

[Role of cutaneous pinch grafts in the healing of patients with dystrophic epidermolysis bullosa wounds: report of four cases]. / Intérêt des greffes de peau en pastilles dans les épidermolyses bulleuses dystrophiques. A propos de quatre cas.

Epidermolysis bullosa (EB) is a heterogeneous group of genetically determined skin fragility disorders in which minor trauma leads to blister formation on the skin. One of the most severe forms is Hallopeau-Siemens recessive dystrophic EB which main cause of mortality is squamous cell carcinoma (SCC). Exeresis of SCC leads to a difficult problem about treating the surgical wound. Most of the time, achieving a split-thickness skin graft on these severely affected EB patients is either too difficult or gives poor quality results. In some cases, flaps could be performed but they represent a too aggressive solution. However cutaneous pinch grafting is really adapted to the healing of these wounds. We have reported 4 cases of patients with recessive dystrophic EB complicated with SCC from 30 mm to 270 mm. After surgical excision of these SCC, dressings have been applied until obtaining a good enough floor for achieving a skin graft. The four patients have been treated by cutaneous pinch grafting. Airway management and monitoring have required particular precautions for avoiding anaesthetic related morbidity. We have noticed no adverse effect. A complete healing of good quality has been obtained in all cases (3 to 16 months of follow-up). No recurrence of SCC has been noticed and donors sites have had got a good healing. Relating to the healing of wounds after exeresis of SCC in case of dystrophic EB, cutaneous pinch grafting represents the most reliable solution with a minimum of physical traumatism.
