Surgical treatment of ingrown toenail without matricectomy.

BACKGROUND: Partial excision of the nail matrix (matricectomy) is generally considered necessary in the surgical treatment of ingrown toenail. Recurrences may occur, however, and poor cosmetic results are frequently observed. OBJECTIVE: The objective is to present a new surgical procedure for ingrown toenail with complete preservation of the nail matrix. METHODS: Twenty-three patients with ingrown toenail were included in this study. The surgical excision was performed 1 week after the completion of treatment of the initial infection. A large volume of soft tissue surrounding the nail plate was removed under local anesthesia. No matrix excision was performed. RESULTS: Short-term results were excellent. No recurrences or severe complications were observed during the minimum 12-months follow-up period. Cosmetic results were remarkable. CONCLUSIONS: Ingrown toenail results from the compression of the lateral nail folds on the nail plate. This study shows that ingrown toenail can be surgically treated without matricectomy. A large volume of soft tissue surrounding the nail plate should be removed to decompress the nail and reduce inflammation. Cosmetic results are excellent and superior to the classical Emmert plasty. Postoperative nail dystrophies and spicule formation are not observed. The main advantage of this surgical approach is the complete preservation of the anatomy and function of the nail to improve both therapeutic and cosmetic results.

Gestion des hypoglycémies après le bypass gastrique [Management of hyperinsulinemic hypoglycemia post-gastric bypass surgery].

Gastric bypass surgery is an effective treatment for morbid obesity, allowing a substantial weight loss together with an improvement of the cardiovascular and metabolic comorbidities, particularly the glucose control. However, after gastric bypassing, an imbalance between sensitivity and insulin secretion may be observed. This disorder gives rise to hyperinsulinemic hypoglycemia (late dumping syndrome) and is characterized by a dizziness that can be disabling. This problem must be distinguished from conditions provoking similar symptoms, as for instance the early dumping syndrome and the food restriction-related hypoglycemia. Since all these conditions need a particular management, their distinction is essential.

Functional assessment of chest wall integrity after methylmethacrylate reconstruction.

BACKGROUND: All patients with extensive resection of the anterolateral chest wall and the sternum followed by reconstruction with methylmethacrylate substitutes were assessed prospectively 6 months after the operation to delineate chest wall integrity with pulmonary function and cine-magnetic resonance imaging. METHODS: Twenty-six patients underwent chest wall reconstruction by use of methylmethacrylate between 1994 and 1998 due to primary tumors in 35%, metastases in 27%, T3 lung cancer in 19%, and debridement for radionecrosis and osteomyelitis in 19% of patients. Three to eight ribs were resected and additional sternum resection was performed in 39% of patients. RESULTS: There was no 30-day mortality. All patients were extubated after the operation without need for reintubation. Prosthesis dislocation occurred in 1 patient and infection in 2 patients during follow-up. Nineteen patients (73%) suffered no restrictions of daily activities. Clinical examination revealed normal shoulder girdle function in 77% of patients. There was no significant difference between preoperative and postoperative FEV1 (forced expiratory volume in 1 second) measurements in patients with lobectomy or wedge resections. Cinemagnetic resonance imaging revealed concordant chest wall movements during respiration in 92% of patients without paradoxical movements or implant dislocations being observed. CONCLUSIONS: Large defects of the anterolateral chest wall and sternum can be reconstructed efficiently with methylmethacrylate substitutes with minimal morbidity and excellent cosmetic and functional outcome.

Blood glucose level on postoperative day 1 is predictive of adverse outcomes after cardiovascular surgery.

AIM: Hyperglycaemia is now a recognized predictive factor of morbidity and mortality after coronary artery bypass grafting (CABG). For this reason, we aimed to evaluate the postoperative management of glucose control in patients undergoing cardiovascular surgery, and to assess the impact of glucose levels on in-hospital mortality and morbidity. METHODS: This was a retrospective study investigating the association between postoperative blood glucose and outcomes, including death, post-surgical complications, and length of stay in the intensive care unit (ICU) and in hospital. RESULTS: A total of 642 consecutive patients were enrolled into the study after cardiovascular surgery (CABG, carotid endarterectomy and bypass in the lower limbs). Patients' mean age was 68+/-10 years, and 74% were male. In-hospital mortality was 5% in diabetic patients vs 2% in non-diabetic patients (OR: 1.66, P=0.076). Having blood glucose levels in the upper quartile range (> or =8.8 mmol/L) on postoperative day 1 was independently associated with death (OR: 10.16, P=0.0002), infectious complications (OR: 1.76, P=0.04) and prolonged ICU stay (OR: 3.10, P<0.0001). Patients presenting with three or more hypoglycaemic episodes (<4.1 mmol/L) had increased rates of mortality (OR: 9.08, P<0.0001) and complications (OR: 8.57, P<0.0001). CONCLUSION: Glucose levels greater than 8.8 mmol/L on postoperative day 1 and having three or more hypoglycaemic episodes in the postoperative period were predictive of mortality and morbidity among patients undergoing cardiovascular surgery. This suggests that a multidisciplinary approach may be able to achieve better postoperative blood glucose control.

Surgical outcomes following repeat non-penetrating glaucoma filtration surgery at a tertiary referral centre

Purpose:To determine the surgical outcomes of patients undergoing repeat deep sclerectomies with collagen implant (DSCI) at a tertiary referral centre. Methods:The medical notes of 208 patients undergoing multiple DSCI were reviewed. Those undergoing repeat DSCI were identified and post operative data for each DSCI were analysed. Group A: the first DSCI; group B: second DSCI; group C: third DSCI. Results:Mean age was 66.8 ±13.0 years. At 12 months, percentage of mean IOP reduction in groups were 18%, 24% and 17% respectively. Mean interval to starting glaucoma medications, re-operation, mitomycin injection and goniopuncture all decreased as the number of operations increased. There was a significant reduction in complete success rates between groups A and B and groups B and C. Few minor complications were observed in all 3 groups. Conclusions:Despite the possibility of bleb independent outflow pathways in patients undergoing non-penetrating surgery, there are significantly reduced success rates in eyes undergoing repeat DSCI. This has important implications for the choice of subsequent operations in patients who have failed non-penetrating filtration surgery.

Evaluation des modifications anatomiques et fonctionnelles de la macula après chirurgie des membranes néovasculaires rétrofovéolaires dans la dégénérescence maculaire liée à l'âge [Evaluation of functional and anatomical changes in the macula after surgery for retro-foveal neovascularization of membranes in age-related macular degeneration].

PURPOSE: The aim of this study was to evaluate the direct effect of surgical treatment of subfoveolar neovascular membranes in age related macular degeneration to macular functions. PATIENTS AND METHODS: Thirteen eyes of 13 patients were included in this study. Macular function was assayed by visual acuity and central visual field using the Octopus perimeter before surgery and in the first three post operative months. Pre and post operative fluorescein angiography frames were digitalized and the size of each lesions were compared. RESULTS: After a 3 months follow up, visual acuity remained stable or improved in 66% of the patients. However, visual acuity was better than 0.1 in 15% of the patients. Central visual field comparison disclosed a significant worsening of the retinal sensitivity in the 3 degree field surrounding the central point. On fluorescein frames, submacular scar was 141% of the size of the neovascular membrane. After a mean follow up of 6.9 months (range 3-14), one case of recurrence occurred. A cataract was observed in 85% of the phakic patients followed for more than six months. CONCLUSION: After a short term follow up, surgery can stabilise visual acuity, even though it remains poor. A worsening of the scotoma in the 3 degrees surrounding the central point is observed. However, patients noticed a subjective visual improvement in 62% of the case.

Cell Therapy Assistance in Reconstructive Surgery for Musculoskeletal Tissues Following Burn and Trauma: Swiss Cellular Transplantation Platform

The sterol compositions of three oceanic jellyfish have been determined using gas chromatographic mass spectrometric techniques involving the use of two separate gas chromatographic column systems. The components in overlapping peaks have been identified by comparison of the mass spectra of peaks in the two column systems using subtractive techniques. A mid-water animal, Periphylla periphylla, was found to contain a very complex and unusual sterol profile including rare 5alpha-stanols, whereas two other oceanic jellyfish Pelagia noctiluca and Atolla wyvillei contained similar mixtures of delta5 sterols to those previously isolated from coastal species.

Multiple nodules of the scrotum: histopathological findings and surgical procedure. A study of five cases.

BACKGROUND: Multiple nodules of the scrotum are uncommonly reported. Their origin is controversial. Treatment is always surgical but the best procedure is still to be determined. MATERIALS AND METHODS: Five new cases are reported with description of the histopathological findings and surgical procedure. RESULTS: Nodules of the scrotum were more frequent in patients with dark skin suggesting an ethnic susceptibility. No other predisposing factors were noted. Screening for disturbances of phosphate or calcium balance was negative. The following histopathological findings were observed: non-calcified epidermoid cysts (3 patients), calcified epidermoid cysts (1 patient) and nodular calcifications without epithelial or glandular structures (1 patient). Subtotal excisions of the scrotum wall using tumescent anaesthesia were performed in all patients without any significant complications. Cosmetic results were excellent. No new lesions were observed during the 1-year follow-up period. CONCLUSIONS: Most cases of multiple nodules of the scrotum are due to non-calcified epidermoid cysts. The term scrotal calcinosis is therefore probably abusively used by many authors. Some cases of nodular calcifications may be due to dystrophic calcification of epidermoid cysts, but calcifications may also occur without any visible epithelial or glandular structure. Subtotal excision of the scrotum wall is a safe and effective surgical procedure to treat multiple nodules of the scrotum. Cosmetic results are excellent and recurrences are rare.

An analysis of the components of pain, function, and health-related quality of life in patients with failed back surgery syndrome treated with spinal cord stimulation or conventional medical management

Objectives: Failed back surgery syndrome (FBSS) patients experience pain, functional disability, and reduced health-related quality of life (HRQoL) despite anatomically successful surgery. Examining sub-dimensions of health outcomes measures provides insight into patient well-being. Materials and Methods: The international multicenter PROCESS trial collected detailed HRQoL (EuroQol-5D; Short-Form 36) and function (Oswestry Disability Index) information on 100 FBSS patients. Results: At baseline, patients reported moderate-to-severe leg and back pain adversely affecting all dimensions of function and HRQoL. Compared with conventional medical management alone, patients also receiving spinal cord stimulation (SCS) reported superior pain relief, function, and HRQoL at six months on overall and most sub-component scores. The majority of these improvements with SCS were sustained at 24 months. Nonetheless, 36-40% of patients experienced ongoing marked disability (standing, lifting) and HRQoL problems (pain/discomfort). Conclusions: Longer-term patient management and research must focus on these refractory FBSS patients with persisting poor function and HRQoL outcomes.

Oral mucosal melanoma: conservative treatment including laser surgery.

Objective: To discuss the convenience of laser surgery as optimal treatment for melanoma of the oral mucosa.Patients and methods: A retrospective evaluation of four patients with primary oral melanomas treated at a single Cancer Institution in Mexico City.Results: Two patients were treated with resection of the melanoma with CO2 laser together with extraction of the involved dental organs and curettage of the alveolar walls. These two cases had melanoma in situ with multiple isolated foci. The third patient had a lesion with vertical growth, who was submitted to partial maxillectomy along with selective dissection of bilateral neck levels I-V with a negative report and the fourth patient had a history of oral nodular melanoma and presented with lymph node metastasis. According to follow-up status, there was no distant metastasis in any of the patients reported here.Conclusion: In our experience, conservative management with CO2 laser is adequate for melanomas of the oral mucosa with extraction of the dental organs and curettage of the alveoli to achieve complete surgical resection microscopically without sacrifice of the quality of life. Management of the neck is controversial. We recommend selective therapeutic resection of the neck only if it is found to be clinically positive. Elective dissection has not shown to have an impact in overall survival.

Perioperative nutrition in abdominal surgery: recommendations and reality.

Introduction. Preoperative malnutrition is a major risk factor for increased postoperative morbidity and mortality. Definition and diagnosis of malnutrition and its treatment is still subject for controversy. Furthermore, practical implementation of nutrition-related guidelines is unknown. Methods. A review of the available literature and of current guidelines on perioperative nutrition was conducted. We focused on nutritional screening and perioperative nutrition in patients undergoing digestive surgery, and we assessed translation of recent guidelines in clinical practice. Results and Conclusions. Malnutrition is a well-recognized risk factor for poor postoperative outcome. The prevalence of malnutrition depends largely on its definition; about 40% of patients undergoing major surgery fulfil current diagnostic criteria of being at nutritional risk. The Nutritional Risk Score is a pragmatic and validated tool to identify patients who should benefit from nutritional support. Adequate nutritional intervention entails reduced (infectious) complications, hospital stay, and costs. Preoperative oral supplementation of a minimum of five days is preferable; depending on the patient and the type of surgery, immune-enhancing formulas are recommended. However, surgeons' compliance with evidence-based guidelines remains poor and efforts are necessary to implement routine nutritional screening and nutritional support.
