SAMCEP Society consensus on the treatment of upper facial lines with botulinum neurotoxin type A: A tailored approach.

BACKGROUND: The safety and efficacy of botulinum neurotoxin type A (BoNTA) treatments are well established, but injection techniques, target muscles, and toxin doses continue to evolve, with each refinement producing improvements in treatment outcomes. The recommendations in this consensus move away from standard templates and illustrate how to tailor treatments to individual patterns and strengths of muscle activity, and patient preferences. METHODS: Seventeen experts in the fields of plastic surgery, dermatology, ophthalmology, otorhinolaryngology, and neurology convened in 2022 to develop consensus-based recommendations for the use of botulinum toxin A for the treatment of horizontal forehead lines, glabellar frown lines, and crow's feet lines that reflect current clinical practice. The focus was on how to tailor injections to individual patients to optimize treatment outcomes. RESULTS: For each upper face indication, consensus members describe how to perform a dynamic assessment to optimize the dose and injection technique for each patient. A tailored treatment protocol is presented for commonly observed patterns of dynamic lines. Units of Inco are defined and the precise location of injection points, illustrated with the use of anatomical images. CONCLUSION: This consensus provides up-to-date recommendations on the tailored treatment of upper facial lines based on the latest research and collective clinical experience of the expert injectors. Optimal outcomes require thorough patient evaluation, both at rest and during animation, using both visual and tactile cues; detailed understanding of facial muscular anatomy and how opposing muscles interact; and use of a BoNTA with high precision to target identified zones of excess muscle activity.

Filler-induced blindness "seen" by ophthalmologists: Case presentation and treatment algorithm.

PURPOSE: Filler-induced blindness (FIB) is the most threatening complication following periocular injection. To date, no standard of care has been established. The goal of this study is to report a new case of FIB with partial visual recovery and present our personalized algorithm for treatment based on fluorescein angiography findings. MATERIALS AND METHODS: Case report with 24 months follow-up and treatment algorithm. RESULTS: Our patient experienced complete vision loss to no light perception following forehead lipofilling. Retinal angiography identified a posterior ciliary artery occlusion. Antiplatelet medication, steroids and intraocular pressure lowering medications were administrated, followed by hyperbaric oxygen treatment (HBOT). Visual acuity improved to +0.8 logMar. The HBOT treatment was monitored by fluorescein angiogram. Based on this case and on the ophthalmic literature on retinal and ciliary artery occlusion, we established a personalized FIB protocol guided by fluorescein angiography. CONCLUSION: Although prevention remains the best treatment, all physicians should be prepared to manage FIB. Prompt management at the office guided by written protocols, as well as emergency kits, are essential. In referral centers, personalized treatment should be undertaken based on fluorescein angiography findings.

Utility of anaerobic bottles for the diagnosis of bloodstream infections.

BACKGROUND: Obligate anaerobes usually account for less than 10% of bacteria recovered from blood cultures (BC). The relevance of routine use of the anaerobic bottle is under debate. The aim of this study was to evaluate the utility of anaerobic bottles for the diagnosis of bloodstream infections (BSI). METHODS: We conducted a 6-month, retrospective, monocentric study in a tertiary hospital. All positive BC were grouped into a single episode of bacteremia when drawn within 7 consecutive days. Bacteremia were classified into contaminants and BSI. Charts of patients with BSI due to obligate anaerobes were studied. RESULTS: A total of 19,739 blood cultures were collected, 2341 of which (11.9%) were positive. Anaerobic bottles were positive in 1528 (65.3%) of all positive BC but were positive alone (aerobic bottles negative) in 369 (15.8%). Overall 1081 episodes of bacteremia were identified, of which 209 (19.3%) had positive anaerobic bottles alone. The majority 126/209 (60.3%) were contaminants and 83 (39.7%) were BSI. BSI due to facultative anaerobes, obligate aerobes and obligate anaerobes were identified in 67 (80.7%), 3 (3.6%) and 13 (15.7%) of these 83 episodes, respectively. BSI due to obligate anaerobic bacteria were reported in 9 patients with gastro-intestinal disease, in 3 with febrile neutropenia and in 1 burned patient. CONCLUSIONS: Anaerobic bottles contributed to the diagnosis of a significant number of episodes of bacteremia. Isolated bacteria were mostly contaminants and non-obligate anaerobic pathogens. Rare BSI due to obligate anaerobes were reported mainly in patients with gastro-intestinal disorders and during febrile neutropenia.

Individual site-specific bone mineral density gain in normocalcemic primary hyperparathyroidism.

UNLABELLED: In this study, we show that successful parathyroidectomy is followed at 1 year by a significant individual bone mineral density (BMD) gain in nearly half of normocalcemic PHPT patients with reduced bone mass. Alkaline phosphatase levels above median were identified as an independent predictor of individual BMD gain in normocalcemic PHPT patients. INTRODUCTION: The aims of this study were to assess bone mineral density (BMD) gains after parathyroidectomy (PTX) in normocalcemic primary hyperparathyroidism (PHPT) at the individual level and to identify predictors of BMD gain after PTX in this context. METHODS: Longitudinal cohort study of 55 PHPT patients referred for low bone mass and mild abnormalities of calcium/phosphorus metabolism, and successfully treated by PTX. BMD gain at 1 year was considered significant if ≥0.030 g/cm(2) at one site or more, without any equivalent BMD loss at another site. A logistic regression analysis was performed to identify predictive factors of individual BMD gain. RESULTS: Among the 55 PHPT patients included, 29 patients with hypercalcemia, 36 patients with normocalcemic PHPT, defined by normal pre-PTX serum total (albumin-corrected) calcium (tCa), including 15 patients with normal ionized calcium (iCa), were identified. At 1 year of PTX, an individual BMD gain was observed in 73.7 % of hypercalcemic, 44.4 % of normocalcemic, and 46 % of PHPT patients with both normal tCa and iCa. Site-specific BMD gains were most important at the spine and hip in all subgroups including patients with normal iCa. Alkaline phosphatase activity above median, which reflects high bone turnover, was predictive of individual BMD gain, both in the overall cohort (OR = 4.9, 95 % CI 1.3-18.9), and in the normocalcemic group: OR = 8.4, 95 % CI 1.4-56.6. CONCLUSIONS: Successful PTX is followed at 1 year by a significant individual BMD gain in nearly half of normocalcemic PHPT patients with osteoporosis. ALP levels above median could contribute to the therapeutic decision in this context.

Esophagojejunostomy after total gastrectomy for caustic injuries.

The objective of the study was to compare outcomes of emergency esophagogastrectomy (EGT) and total gastrectomy with immediate esophagojejunostomy (EJ) in patients with full-thickness caustic necrosis of the stomach and mild esophageal injuries. After caustic ingestion, optimal management of the esophageal remnant following removal of the necrotic stomach remains a matter of debate. Between 1987 and 2012, 26 patients (men 38%, median age 44 years) with isolated transmural gastric necrosis underwent EGT (n = 14) or EJ (n = 12). Early and long-term outcomes of both groups were compared. The groups were similar regarding age (P = 0.66), gender (0.24), and severity of esophageal involvement. Functional success was defined as nutritional autonomy after removal of the jejunostomy and tracheotomy tubes. Emergency morbidity (67% vs. 64%, P = 0.80), mortality (17% vs. 7%, P = 0.58), and reoperation rates (25% vs.14%, P = 0.63) were similar after EJ and EGT. One patient (8%) experienced EJ leakage. One patient in the EJ group and 13 patients in the EGT group underwent esophageal reconstruction (P < 0.0001). Aggregate in hospital length of stay was significantly longer in patients who underwent EGT (median 83 [33-201] vs. 36 [10-82] days, P = 0.001). Functional success after EJ and EGT was similar (90% vs.69%, P = 0.34). Immediate EJ can be safely performed after total gastrectomy for caustic injuries and reduces the need of further esophageal reconstruction.

Functional disorders and quality of life after esophagectomy and gastric tube reconstruction for cancer.

Functional disorders such as delayed gastric emptying, dumping syndrome or duodeno-gastro-esophageal reflux occur in half of the patients who undergo esophagectomy and gastric tube reconstruction for cancer. The potential role for pyloroplasty in the prevention of functional disorders is still debated. Antireflux fundoplication during esophagectomy can apparently reduce the reflux but at the cost of increasing the complexity of the operation; it is not widely used. The treatment of functional disorders arising after esophagectomy and gastroplasty for cancer is based mainly on dietary measures. Proton pump inhibitors have well documented efficiency and should be given routinely to prevent reflux complications. Erythromycin may prevent delayed gastric emptying, but it should be used with caution in patients with cardiovascular disorders. In the event of anastomotic stricture, endoscopic dilatation is usually efficient. Problems related to gastrointestinal functional disorders after esophageal resection and gastric tube reconstruction do not significantly impair long-term quality of life, which is mainly influenced by tumor recurrence.

Oesophagogastrectomy and pancreatoduodenectomy for caustic injury.

BACKGROUND: The justification for pancreatoduodenectomy (PD) for extended duodenal and pancreatic caustic necrosis is still a matter of debate. METHODS: This was a retrospective evaluation of patients who underwent PD in association with oesophagogastrectomy from a large single-centre cohort of patients with caustic injuries. Morbidity, mortality and long-term outcome were assessed. RESULTS: PD was performed in 18 (6·6 per cent) of 273 patients who underwent emergency surgery for caustic injuries. Biliary and pancreatic duct reconstruction during PD was performed in ten and six patients respectively. Seven patients died and 17 experienced operative complications after PD for caustic injuries. Twelve patients required at least one reoperation. Specific PD-related complications occurred in 13 patients. Initial (P = 0·038) or secondary (P < 0·001) extension of necrosis to adjacent organs were independent predictors of operative death. After a median follow-up of 24 months following reconstruction, three patients had recovered nutritional autonomy. In an intention-to-treat analysis, functional success was recorded in three patients and the 5-year survival rate was 39 per cent after PD for caustic injury. CONCLUSION: PD can save the lives of patients with caustic injuries extending beyond the pylorus, but has poor functional outcome. Immediate pancreatic duct reconstruction should be preferred to duct occlusion to decrease the rate of pancreatic complications.

Esophageal perforations.

The incidence of esophageal perforation (EP) has risen with the increasing use of endoscopic procedures, which are currently the most frequent causes of EP. Despite decades of clinical experience, innovations in surgical technique and advances in intensive care management, EP still represents a diagnostic and therapeutic challenge. EP is a devastating event and mortality hovers close to 20%. Ambiguous presentations leading to misdiagnosis and delayed treatment and the difficulties in management are responsible for the high morbidity and mortality rates. A high variety of treatment options are available ranging from observational medical therapy to radical esophagectomy. The potential role of interventional endoscopy and the use of stents for the treatment of EP seem interesting but remain to be evaluated. Surgical primary repair, with or without reinforcement, is the preferred approach in patients with EP. Prognosis is mainly determined by the cause, the location of the injury and the delay between perforation and initiation of therapy.

[Colonic interposition for esophageal replacement after caustic ingestion]. / Reconstruction oesophagienne pour séquelles de brûlure caustique: coloplasties, mode d'emploi.

Retrosternal coloplasty is the gold standard for esophageal reconstruction after caustic injury of the digestive tract. Complete preoperative otolaryngology evaluation and the control of the psychiatric disease are key factors for success. In the absence of controlled studies, the choice between the right and the left colon graft relies on the anatomy of the blood supply to the colon and on the individual surgeon's preference. Treatment of associated pharyngeal and laryngeal injuries is mandatory at the time of esophageal reconstruction. In experienced hands mortality rates are less than 5% but specific postoperative complications (graft necrosis, leakage, anastomotic stricture) are high. The low risk of cancer development in the by-passed esophagus does not justify routine esophagectomy at the time of reconstruction. Sixty to eighty percent of patients would finally retrieve nutritional autonomy after coloplasty for caustic injury. Late acquired dysfunctions of the coloplasty (anastomotic strictures, graft redundancy) requiring revision surgery occur frequently and might jeopardize an already fragile functional result. Timely diagnosis and treatment of such complications and the necessity of continuous psychological surveillance justify the need for long term follow up in these patients.

[Colonic lipoma: case report and literature review]. / Lipome colique : cas clinique et revue de la littérature.

Colonic lipoma is a rare benign tumor infrequently met in clinical practice. We report a case of symptomatic lipoma of the ascending colon in a 61-year-old woman. Diagnosis was suspected on CT scan. Colotomy with lipectomy was performed. The diagnosis was confirmed by histological examination. Reviewing the literature and combining with our experience, we discuss the clinical features, diagnosis and treatment of this uncommon disease.

[Laparoscopic partial splenectomy using the Harmonic Scalpel. Two case reports]. / Splénectomie partielle par laparoscopie et ultracision. A propos de deux cas.

For the extirpation of a benign splenic cyst, partial splenectomy is an appropriate approach, since there is significant long-term morbidity following total splenectomy. We report two cases of laparoscopic partial splenectomy for benign splenic cyst. The use of the harmonic scalpel along with segmental ligation of the splenic pedicle allowed the completion of these interventions with minimal blood loss.

A very high incidence of low 25 hydroxy-vitamin D serum concentration in a French population of patients with primary hyperparathyroidism.

Since the demonstration that vitamin D status might influence the clinical and biological expression of primary hyperparathyroidism (PHPT), a serum 25-hydroxy vitamin D (25-OHD) concentration of 50 nmol/l has been considered by an expert panel as the minimum level to be maintained in asymptomatic PHPT patients. Two yr after this recommendation, we aimed to evaluate the frequency of serum 25-OHD concentrations below this threshold in PHPT patients. In the present study, serum 25-OHD, second- and third-generation PTH, calcium, phosphate, magnesium, albumin and creatinine were measured in 72 out 145 consecutive PHPT patients operated on in our Endocrine Surgery Department, in whom blood samples were available before as well as two days after surgical intervention. Before surgery, the frequency of serum 25-OHD levels <50 nmol/l ranged from 91.5 to 100% whatever the classification used to identify patients: whole group, symptomatic vs asymptomatic, patients with calcium levels >3 vs <3 mmol/l. 25-OHD concentrations correlated negatively with the weight of adenoma, PTH levels, and total calcium concentrations measured before surgery. Pre-operative PTH levels, whatever the assay used, and total calcium concentrations were positively and significantly correlated. Two days post-surgery, 13 patients were moderately hypocalcemic. Neither pre-surgery 25-OHD nor PTH, calcium or phosphorus level or adenoma weight were predictive of post-operative hypocalcemia. The dramatic frequency of low 25-OHD concentrations in our PHPT patients demonstrates that the above-mentioned recommendation is far from being applied in France despite evidence of worsening expression of PHPT with decreasing 25-OHD serum levels.

[Minimally invasive esophagectomy: prospective evaluation of laparoscopic gastric mobilization]. / Oesophagectomie mini-invasive: évaluation prospective de la gastrolyse coelioscopique.

OBJECTIVE: Esophagectomy carries high morbidity, mainly due to respiratory complications. In digestive surgery, postoperative outcome is generally improved by minimally invasive surgery. A prospective study was conducted to evaluate feasibility and postoperative outcome of minimally invasive esophagectomy (MIE). METHODS: From July 2001 to June 2004, 20 patients underwent esophagectomy with laparoscopic gastric mobilization (LGM) for squamous cell carcinoma (N=11), adenocarcinoma (N=7), Barrett's esophagus with high-grade dysplasia (N=1), and long peptic stricture (N=1). Tumours (N=19) were located on the cardia (N=5), on the lower third of the oesophagus (N=10), on the median third (N=3), and on the upper third (N=1). Following LGM, transthoracic (N=19) or transhiatal (N=1) oesophagectomy was performed. RESULTS: Complete LGM was achieved in all cases. Mean operative time for LGM was 197+/-48 minutes. In the 19 patients operated for tumours, 18 underwent R0 resection. Eleven patients (55%) developed postoperative complications, mainly (30%) respiratory. Intrathoracic anastomotic leakage occurred in 2 patients, with favourable outcome. Pylorospasm (N=1) was the only intraabdominal complication. One patient died (5%). CONCLUSION: Esophagectomy with LGM is feasible with few specific complications. However, no decrease in morbidity could be observed with this technique. Further studies are required to evaluate if thoracoscopy could improve the postoperative course after LGM and to validate oncologic safety of MIE.

[Gastrinomas in multiple endocrine neoplasia type-1. A 127-case cohort study from the endocrine tumor group (ETG)]. / Les gastrinomes dans les néoplasies endocriniennes multiples de type 1. Une étude de cohorte de 127 cas du groupe des tumeurs endocrines (GTE).

UNLABELLED: On July 2000, 127 gastrinomas (31.1%) were studied by the Endocrine Tumour Group (GTE) using a 408-patient cohort of Multiple Endocrine Neoplasia Type 1 patients. The aim of this study was to assess clinical, biological, surgical data as well as their trends over three periods (<1980-1980/1989->1990). A Zollinger-Ellison syndrome (SZE) was present in 96% of the cases. Mean age at the onset of the disease was 39.4 years. There were 55.9% of men. Synchronous liver metastasis was present in 7.1%. Taken independently, the positivity of the four main diagnosis tests decreased over the time. The diagnosis of oesophagitis increased (4.5-29.7%), as well as the size of the resected tumours (9.9-16.8 mm). There was an increase in the familial background diagnosis (73.1-80%), an increasing use of Octreoscan scintigraphy and transduodenal ultrasound with positive detection of metastasis and tumours in 81.3% and 92.3%, respectively after 1991. Patients were operated on less frequently (96-52.5%), less frequently from the pancreas (87.5-37.5%), and from the gastro-intestinal tract (70.8-30%). The relative percentage of major pancreatic resections increased (with at least removal of the duodenum and the pancreatic head) (10-26.7%). The operative mortality disappeared. Six out of the seven patients (85.7%) who benefited from major pancreatic resections normalized their gastrine level postoperatively versus 15% in less radical techniques. Overall 5 years survival was 90 +/- 4.4%. Survival increased after 1985 (85 +/- 4.8% versus 95 +/- 3.6, P = 0.1). CONCLUSION: SZE in NEM1 were diagnosed at an earlier stage and were less frequently operated on. Nevertheless, the incidence of synchronous metastasis did not change significantly. Patients were mainly operated on for gastric emergencies and pancreatic tumours in order to prevent metastasis without mortality after 1991.

[Extensive digestive caustic burns: what are the limits for resection? A series of 12 patients]. / Brûlures digestives extensives par caustiques : Quelles limites à l'exérèse ?. A propos de 12 patients.

AIM OF THE STUDY: To report the results of oesogastric resections extended to surrounding organs following caustic ingestion, and to precise indications for resection and results of reconstruction. PATIENTS AND METHODS: From 1988 to 2001, 12 patients underwent oesophago-gastrectomy, extended to duodenum and pancreatic head (n = 6), jejunum (n = 4), colon (n = 2), spleen (n = 2) or pancreatic body (n = 1). Early morbidity and mortality, specificities of reconstruction, and quality of oral feeding were assessed retrospectively. RESULTS: Mean intensive care unit stay was 50 days (range: 16-152 days). All patients developed complications. Six patients were reoperated for secondary extension of caustic burns, mainly to colon (n = 4), small bowel (n = 2) and pancreas (n = 2). Three patients died on postoperative days 17, 20, and 130. Secondarily, eight patients (75%) underwent a substernal right ileocoloplasty. Six patients (50%) survived initial resection, and esophageal reconstruction. After a mean follow-up of 35 months (range: 7-87 months), four patients (33%) eat normally. CONCLUSIONS: After caustic burn, oesogastric resections extended to surrounding organs are associated with high morbidity and mortality. However, return of normal oral feeding can be expected in 33% of cases. Secondary extension of caustic burns to adjacent organs is a common eventuality, and may lead to prompt reintervention. Massive injury to small bowel or colon may compromise digestive function or secondary esophageal reconstruction, and thus may be the reasonable limit for resection.
