OBJECTIVES Complications of pharyngitis (peritonsillar abscess, retropharyngeal abscess, and cervical cellulitis) are rare, but appear to be on the increase over recent years and many of these patients have been treated by anti-inflammatory drugs prior to admission. The purpose of this study was to review the current epidemiological data concerning these complications and investigate a possible correlation with anti-inflammatory drug use. MATERIAL AND METHODS A single-centre retrospective review of epidemiological, clinical and microbiological data was performed on the medical charts of patients hospitalised for peritonsillar abscess, retropharyngeal abscess or cervical cellulitis between 2005 and 2010. RESULTS Over a six-year period, 163 patients were hospitalised for complications of pharyngitis, with a sex-ratio of 1.82 (104/57). The number of cases of peritonsillar abscess (PTA) increased from 13 to 28 cases per year from 2005 to 2010 and the number of cases of retropharyngeal abscess increased from three to six cases per year over the same period. The number of cases of cellulitis remained stable with an average of 1.82 cases per year. Each year, significantly more patients with an abscess were admitted to our unit with a history of anti-inflammatory drug use (13.3 ± 4.6) than without anti-inflammatory drug use (7.8±4.3) (P<0.01). Micro-organisms were identified in 80% of cases, with mixed strains in 73% of cases, Streptococcus in 72% of samples and Streptococcus pyogenes in 19% of cases of PTA. A favourable outcome was observed in all patients in response to medical and surgical treatment. CONCLUSION In line with the literature, we observed an increasing incidence of complications of pharyngitis. The present series comprised significantly more patients admitted for PTA with a history of anti-inflammatory drug use. A multicentre prospective controlled study in Nantes on a large cohort is currently underway and will probably confirm these preliminary results.

CONTEXT Treatment of infected nasal polyposis. MATERIAL AND METHODS Multicenter interventional prospective double-blind randomized study with matched groups: treatment with tobramycin aerosol versus isotonic saline aerosol. The study population included 55 patients: 23 receiving isotonic saline aerosol and 32 receiving tobramycin. A novel device (Easynose®) was used with an original principle limiting pulmonary deposition and ensuring homogeneous peripheral deposition in the nasal cavities. OBJECTIVES The principal objective was to compare bacteriological eradication between tobramycin 150mg/3ml versus isotonic saline, both administered by nebulization via the Easynose® device. RESULTS AND CONCLUSION Tobramycin aerosol administered via the Easynose® device showed significantly better bacteriological eradication than isotonic saline.

Variability in facial-muscle innervation: A comparative study based on electrostimulation and anatomical dissection: Variability in facial-muscle innervation

Facial‐nerve palsy is the most common complication during facial surgery. However, there are few detailed reports on the distribution of the terminal branches of the facial nerve to the mimetic muscles. This also applies to the communicating branches. The aim of our study was to assess the variability of communicant and terminal branches of the facial nerve in humans. This prospective study involved anatomical dissections and intraoperative electric stimulation of facial nerves. We first performed 30 dissections to define the branching patterns of the extracranial facial nerve, with particular focus on the penetrating points into the mimetic muscles. We then studied and compared these preliminary data with 14 operative facial stimulations conducted during parotidectomies. Each trunk and branch received systematic electrostimulation. The electrostimulation and facial‐and‐neck movements were analyzed by two independent reviewers. The peripheral branching and intercommunication of the facial branches were highly variable. Combining electrostimulation and dissections, the frontalis muscle, the depressor labii inferioris and the platysma showed little nerve recuperation whereas the sphincter muscles (orbicularis ori and oculi) were anatomically protected. Facial‐muscle innervation differed among individuals. We found complex variations in the facial branching mode. Our study highlights the branches and corresponding areas that could be considered anatomically risky. Clin. Anat. 32:169–175, 2019.

PurposeThe aim of our study was to clarify the origin of the inferior vesical artery and determine its existence in women.MethodsThis descriptive study is based on 25 dissections (6 male and 19 female cadavers). We dissected the internal iliac artery and its branches from the iliac bifurcation, bilaterally and comparatively. Each arterial branch supplying the bladder was identified and dissected as far as the bladder.ResultsIn total, 50 topographies of the bladder vascularization were visualised. The inferior vesical artery was observed in 92% of the male subjects and in 47.4% of the female subjects. In the male cadavers, it arose from the internal iliac artery in 72.7% of cases and from the umbilical artery in 27.3% of cases. In the female cadavers, it arose from a common trunk with the umbilical artery and the uterine artery in 33.3% of cases and directly from the umbilical artery in 33.3% with one terminal branch supplying the upper part of the vagina. In two female subjects, the inferior vesical artery arose from the first segment of the uterine artery (22.2%), and in one subject from the obturator artery (11.1%).ConclusionsThe inferior vesical artery is not specific to the male sex. The contradictions found in the literature of this artery are due to the variations observed in pelvic vascularization and to the close connections between vaginal and bladder vascularisation in women. However, surgeons should consider these variations, to prevent bladder devascularization by non-selective ligation.
