Use of injectables in rhinoplasty retouching: Towards an evolution of surgical strategy? Literature review.

BACKGROUND: Surgical revision rate of rhinoplasty is from 5% to 15% in literature. OBJECTIVE OF REVIEW: In the context of post-rhinoplasty deformities, we aim to investigate the modalities of using injectables, their impacts on revision rate of rhinoplasty as well as their influences on the surgical strategy. TYPE OF REVIEW: We realized an international literature review to collect informations on main studies reporting series of exclusive secondary medical rhinoplasties or mixed primary/secondary medical rhinoplasties, as well as per-operative injection. SEARCH STRATEGY: The databases of the National Library of Medicine, Cochrane Library, Embase and Web of science were explored using the following Boolean string: (rhinoplasty OR nose) AND (injectable OR fillers OR hyaluronic acid OR calcium hydroxylapatite). The search was limited to the English language literature for studies published from 2007 up to December 2019. RESULTS: Fifteen cohort studies were included. Hyaluronic acid was the most commonly used injectable for rhinoplasty revision. Patient satisfaction rates varied between 80% and 100%. Reinjections were necessary in about 20 to 50% of cases whatever the used injectables. Minor complications (swelling, bruising, erythema) were frequent after filler injections (4%). Severe complications such granulomas or vascular embolism causing skin necrosis/visual impairment were rare (0.4%). Their physiopathology, management and prevention are detailed. CONCLUSIONS: The use of injectables seems to reduce the need of secondary surgical rhinoplasties. It can be expected that an evolution in surgical practices will result from injectables using, but it will be possible only if the technique is perfectly understood to avoid potentially serious vascular complications.

In-vitro development of an effective treatment for Acanthamoeba keratitis.

The aim of this study was to develop an in-vitro topical treatment for Acanthamoeba keratitis (AK) effective against cysts and trophozoites. Qualitative assays were performed with voriconazole, chlorhexidine, propamidine, cellulase, tobramycin, ciprofloxacin and paromomycin as monotherapy and various combinations. Riboflavin with ultraviolet-A (R + UV-A) as monotherapy or combined with voriconazole and moxifloxacin was also tested. Quantitative assays to assess cyst viability after treatment were performed for the chemicals that showed the highest activity in the qualitative assays. Paromomycin and propamidine did not show antiamoebic activity. Regardless of the total dose, no amoebicidal effect was observed for R + UV-A. Tobramycin, ciprofloxacin, voriconazole, chlorhexidine and cellulase were selected for quantitative assays because they appeared to cause greater damage to the structure of amoebae. Chlorhexidine and ciprofloxacin were the most active against Acanthamoeba spp. as monotherapy. Among the combinations evaluated, ciprofloxacin-voriconazole-chlorhexidine showed the greatest amoebicidal activity, with severe damage of the cellular membrane and an important decrease in cell concentration. In summary, ciprofloxacin as monotherapy and in combination with voriconazole and chlorhexidine has been classified as promising treatment. Additional in-vivo studies in animal models and clinical trials in patients with AK should be considered to confirm the efficacy of ciprofloxacin.

Oxaliplatin- or irinotecan-based chemotherapy for metastatic colorectal cancer in the elderly.

The tolerance and efficacy of oxaliplatin and irinotecan for metastatic colorectal cancer are unknown in elderly patients. Methods. All consecutive patients over 74 years treated with oxaliplatin or irinotecan for metastatic colorectal cancer were enrolled. The tumour response was assessed every 2-3 months and toxicity was collected at each cycle according to World Health Organisation criteria. A total of 66 patients were enrolled from 12 centres. The median age was 78 years (range, 75-88 years); 39 patients had no severe comorbidity according to the Charlson score. In total, 44 and 22 patients received oxaliplatin or irinotecan, respectively, in combination with 5-fluororuracil+/-folinic acid or raltitrexed in 64 patients. A total of 545 chemotherapy cycles were administered in first (41%), second (51%) or third line (8%). A dose reduction occurred in 190 cycles (35%). Complete response, partial response and stabilisation occurred in 1.5, 20 and 47% of patients, respectively. The median time to progression and overall survival were 6.8 and 11.2 months in first line and 6.3 and 11.6 months in second line, respectively. Grade 3 and 4 toxicity occurred in 42% of patients: neutropenia 17%, diarrhoea 15%, neuropathy 11%, nausea and vomiting 8% and thrombopenia 6%. There was no treatment-related death. In selected elderly patients, chemotherapy with oxaliplatin or irinotecan is feasible with manageable toxicity.

Gastric linitis adenocarcinoma and carcinomatous meningitis: an infrequent but aggressive association--report of four cases.

Carcinomatous meningitis (CM) is a very rare complication of gastrointestinal malignancies and especially gastric adenocarcinoma. Linitis plastica (LP), which is a specific form of gastric neoplasia, locally penetrates through the gastric wall to reach the peritoneum. Lymph node involvement is frequent and metastatic sites are almost exclusively observed in the abdominal cavity. The meningeal localization is extremely rare with only a few cases described in the literature. We report here, over a five-year period, four cases of CM on a total of eighty linitis cases diagnosed and treated in our institution, which represent 5% of a non selected linitis population. The clinical manifestations were clearly poor, and characterized by aspecific neurological signs. The diagnosis was made by the discovery of signet cells in the cerebrospinal fluid. Invasive treatment, consisting of intrathecal infusion of chemotherapy, was undertaken with mixed clinical response and no cytological normalization of the cerebrospinal fluid (CSF). In conclusion, our observation which is based on a large series of successive gastric linitis, demonstrates a 5% frequency of developing CM with a predominance among metastatic patients. Furthermore, the diagnosis of CM must be done as soon as possible because of the clear effectiveness of a therapeutic approach on the improvement of symptoms and quality of life.

Emergency admission for cancer: a matter of survival?

The objective of this study was to compare the pre-hospital health care process, clinical characteristics at admission and survival of patients with a digestive tract cancer first admitted to hospital either electively or via the emergency department. The study involved cross-sectional analysis of information elicited through personal interview and prospective follow-up. The setting was a 450-bed public teaching hospital primarily serving a low-income area of Barcelona, Catalonia, Spain. Two hundred and forty-eight symptomatic patients were studied, who had cancer of the oesophagus (n = 31), stomach (n = 70), colon (n = 82) and rectum (n = 65). The main outcome measures were stage, type and intention of treatment and time elapsed from admission to surgery; the relative risk of death was calculated using Cox's regression. There were 161 (65%) patients admitted via the emergency department and 87 (35%) electively. The type of physician seen at the first pre-hospital visit had more often been a general practitioner in the emergency than in the elective group (89% vs 75%, P < 0.01). Emergency patients had seen a lower number of physicians from symptom onset until admission, but two-thirds had made repeated visits to a primary care physician. Emergency patients were less likely to have a localized tumour and a diagnosis of cancer at admission, and surgery as the initial treatment. Median survival was 30 months for elective patients and 8 months for emergency patients (P < 0.001), and the relative risk of death (RR) was 1.83 (95% confidence interval, CI, 1.32-2.54). After adjustment for strong prognostic factors, emergency patients continued to experience a significant excess risk (RR = 1.58; CI 1.10-2.27). In conclusion, in digestive tract cancers, admission to hospital via the emergency department is a clinically important marker of a poorer prognosis. Emergency departments can only partly counterbalance deficiencies in the effectiveness of and integration among the different levels of the health system.

Do we believe what patients say about their neoplastic symptoms? An analysis of factors that influence the interviewer's judgement.

In order to analyze factors that influence an interviewer's judgement of the validity of responses given by patients on the duration of their neoplastic signs and symptoms, 183 consecutive symptomatic patients hospitalized for a digestive tract neoplasm were personally interviewed. The validity of the answers was judged by the interviewers to be high in 156 cases (85%), and low in 27 (15%). The subjective validity of the interview (SVI) was inversely related to the time elapsed from first medical symptom to interview (TFMSI), even after adjusting for the duration of the interview (p < 0.05). SVI was not influenced by whether patient and interviewer agreed on the first symptom. SVI was inversely related to educational level (p < 0.01) and to occupational class (p = 0.04). Patients whose Karnofsky's Index (KI) was > or = 80 were over twice as likely to yield valid responses (TFMSI-adjusted odds ratio [OR] = 2.82, p = 0.037). Multivariate analyses selected education, TFMSI and KI as independent predictors of the interviewer assessment. The SVI of patients admitted to the hospital through the Emergency Department was lower than that of subjects whose admission was planned (OR = 6.49, p = 0.005). In this study SVI related in a logical manner to the characteristics of the interview, of the subjects and of their clinical course. It hence appeared to reasonably estimate the validity of data collected. Identifying factors that affect the reliability of patients' responses would help increase the validity of studies on the duration of cancer symptoms.

Predictors of the interval between onset of symptoms and first medical visit in patients with digestive tract cancer.

Lack of effective population screening programmes for digestive tract cancer makes a prompt diagnosis of symptomatic patients the primary option for early detection. The objective of the study was to analyze the characteristics and determinants of the interval between the first medical symptom and the first medical visit (ISV) in a sample of symptomatic patients of mid-low socioeconomic level admitted to hospital for a digestive tract cancer. During two years, 183 patients were personally interviewed with a structured questionnaire designed to elicit initial symptoms of digestive cancer. Fifty-seven percent consulted a physician during the first month after onset of symptoms, and over two-thirds did so within the first 2 months, but it took more than 3 months for 22.4% of the patients. In univariate analyses, the ISV was longer among patients illiterate, unemployed and in the lower social classes. The interval was also significantly longer when the physician-interviewer judged that the patient did not correctly identify the first symptom (p<0.05). In multivariate analyses, the chance of a longer ISV was 2.8 times higher in men; 16 times higher in unemployed patients; 9 times higher in patients with a first symptom of the lower digestive tract; and it increased 8-fold in subjects who attributed no importance to the first manifestation (all p<0.05). In spite of virtually universal health coverage, social factors seemed to act as barriers to seeking medical help in a subgroup of patients. Their procrastination was also related to the nature of the initial symptoms. Achieving an early clinical detection of digestive cancers may be difficult in some segments of the population, and may require substantial improvements in access to and the efficiency of the health system.

Disagreement between hospital medical records and a structured patient interview on the type and date of the first symptom in cancers of the digestive tract.

Medical records have often been found to be less reliable than interviews to patients when data on the initial signs and symptoms of cancer, and the out-of-hospital diagnostic process are sought; in spite of this, a large body of research on "diagnostic delay" in cancer is based on clinical records. As part of a study on delay in neoplasms of the digestive tract we analyzed the agreement on the type and date of the initial symptom between hospital records and a structured personal interview. Records were abstracted for a random sample (N = 60) of 183 patients interviewed. Concordance on the date of the first symptom was deemed to exist if the difference was +/- 30 days. The Kappa index (kappa) and the overall proportion of agreement (with its corresponding 95% confidence interval) were used. Medical records and structured personal interviews were concordant on the type of the first neoplastic symptom in only 61% of cases (kappa = 0.50): 67% in esophagus cancer (kappa = 0.49), 60% in stomach cancer (kappa = 0.52), and 61% in colorectal cancer (kappa = 0.50). Records underestimated the occurrence of anorexia as first symptom and overestimated weight loss and dysphagia. Only 56% of cases were date-concordant, the agreement being lower in colorectal cancer (46%) than in esophageal (67%) and stomach cancer (75%). Records indicated the first symptom to have occurred at a later date than interviews in 33% of cases; overall, a study based on hospital records would have underestimated the symptom to diagnosis interval by 2.2 months per patient. Only 40% of cases were totally (symptom and date) concordant. Marked discrepancies may exist between the information contained in medical records and what patients report during a structured interview. The quality of medical records data on the duration and nature of cancer symptoms should be assessed before its use in etiologic and evaluative research.

[Attic emptying in cholesteatoma and precholesteatoma states. Technique, indications and results]. / L'évidement attical dans les états cholestéatomateux et précholestéatomateux. Technique, indications, résultats.

A surgical procedure different from the open or closed technique is presented. The attic is emptied through the meatus after a retromeatal access to the antromastoidal cavities. By blocking the aditus ad antrum, the procedure produces an antrio-attic microcavity with no recessus. Results of resection of epidermal lesions are quite satisfactory with a low rate of residual pathology. Retraction pouches do not develop because the mastoid is excluded and no attic recessus is formed. Surveillance of the cavity is easy and the disadvantages of functional sequellae inherent in open techniques are avoided. The preliminary results would confirmed the quality of the procedure. In 22 cases, there were 3 residual perles on the windows and 2 retraction pouches (anterior and posterosuperior). This technique is indicated in precholesteatoma states with poor prognosis and cholesteatomas of the attic. For more advanced lesions, this technique is less reliable and the open procedure is required.

[Cherubism. Apropos of a major case]. / Le chérubisme. A propos d'un cas majeur.

Cherubism is a benign, hereditary giant-cell lesion located in the mandible and both maxillaries, which appears during childhood as a painless bilateral swelling, progressing until puberty and then receding spontaneously without normally requiring any treatment. In a previous publication, the authors had presented the case of three young children from the same Algerian sibship, who were eventually all operated when surgery proved to be necessary. The case published in this presentation is that of a young Italian girl presenting with a monstrous form of cherubism. In view of this malignant form, the authors decided to perform surgical treatment in several steps in order to decrease this abnormality as much as possible, considering the physical and psychological consequences reported.

[Severe aplasia of the ear: management and surgical indications]. / Aplasies majeures de l'oreille: prise en charge et indications chirurgicales.

Severe aplasia of the ear raises both a cosmetic and a functional problem. Surgery is often performed starting at four or five years of age but early management is essential. The need for a hearing aid should be evaluated at the age of six months. At birth, the infant should have investigations for concomitant malformations, which are common, and for etiologic factors. Functional surgery to create a canal, tympanic membrane, and chain of ossicles should be performed only in bilateral forms. Satisfactory cosmetic results can be achieved by cartilage autografting according to Brent's technique.

[Muco-epidermoid tumors of the parotid gland. Diagnostic and therapeutic attitudes]. / Les tumeurs muco-épidermoïdes de la parotide. Attitude diagnostique et thérapeutique.

On the basis of a retrospective series of thirteen cases treated between 1969 and 1989, the authors have studied the diagnostic and therapeutic issues connected with mucoepidermoid parotid tumors. The diagnosis is histopathological, but it is sometimes difficult to establish because of the histological polymorphism of these tumors. The degree of malignancy is variable and generally low. It is determined according to clinical and histopathological criteria, although there is not always a correlation between these criteria and the malignancy of evolution. Surgical exeresis is sufficient to cure most of these tumors. However, postoperative radiation therapy is indicated in case of tumoral invasion. Out of the ten cases of mucoepidermoid parotid tumor, nine were treated in first intention with exclusive surgery, and one case underwent postoperative radiation therapy. No local recurrence was noted. Out of the three patients who had a second-intention surgical exeresis, one died after repeated recurrence in spite of the complementary radiation therapy.
