The Pott puffy tumor is a subperiosteal abscess of the frontal bone that appears as a localized swelling of the overlying region of the forehead associated with frontal osteomyelitis. The authors report the case of an 11-year-old boy who presented with a 6-week history of frontal headaches and a recent sudden-onset, progressively enlarging swelling of his midline forehead associated with immediate relief of headaches. A computed tomography (CT) study revealed 1) a subperiosteal abscess with intracranial extension through the perforated posterior table of the frontal sinus and 2) a large epidural abscess overlying a compressed and narrowed superior sagittal sinus. Emergency surgical relief of the epidural abscess, curettage of the osteomyelitic bone, and excision of the periosteal granulomatous puffy lump were performed. A 6-week course of intravenous antibiotic medication was completed, and the patient had an excellent recovery. The Pott puffy tumor remains a serious complication of frontal sinusitis. In the past 5 years, the frequency of published pediatric cases has increased. Undiagnosed or partially treated frontal sinusitis may lead to this serious complication, and the apparent increase in incidence rate may suggest that this complication of frontal sinusitis could be underestimated in clinical practice. The authors conclude that early diagnosis and complete treatment of frontal sinusitis is crucial.

The objective of this study was to investigate the outcome of neurosurgical treated children with suppurative intracranial complications (SIC) of sinusitis over the past 28 years in our hospital. We reviewed the cases notes of a series of 11 consecutive paediatric patients, who were subjected to surgery for sinusitis-induced SIC, retrospectively. Eleven children (10 males and only one female) were underwent neurosurgical procedure in our hospital between 1978 and 2006. Their age at the time of diagnosis ranging from 13 to 17 years (mean 15.27 years, SD 1.737). The commonest presenting symptoms were headaches (81.8%) followed by vomiting (45.5%) and swelling of the forehead (45.5%). The most often involved sinus was the frontal sinus (63.6%) and sinus surgery was performed in eight (72.72%) of 11 cases. The neurosurgical procedures carried out included burr hole drainage or aspiration of abscess in five cases, craniotomy and evacuation of empyema in seven cases and craniectomy in two cases. Four (36.4%) of 11 patients had more than one neurosurgical operation due to re-accumulation of pus and worsening of their clinical status. Most common pathogen was Streptococcus species (81.9%), and anaerobes were isolated in three (27.3%) cases. Postoperative antibiotic treatment lasted from 26 to 70 days (mean 45.45 days, SD 15.280). Epilepsy was diagnosed in two patients, postoperatively. During the follow-up period, persistent focal neurological deficits were present in five (45.5%) of 11 patients. Interestingly, five (45.45%) cases occurred over the last 2 years (2005-2006) and the other six over the previous 16 years (1978-2006). Prompt and aggressive medical and neurosurgical intervention is required, aiming to minimize the morbidity and mortality and also to maximize the favourable outcome of those children.

This study did not demonstrate a correlation between the presence of pre-pontine adhesions, double or thickened floor of third ventricle and ETV success. In patients without previous shunt, stoma size may correlate with success. CSF leak was strongly associated with failure.

IntroductionPhysiological hand tremor occurs naturally, due to oscillations of the upper extremities. Tremor can be exacerbated by stress and anxiety, interfering with fine motor tasks and potentially impact on surgical performance, particularly in microsurgery. We investigated the link between tremor, anxiety and performance in a neurosurgical module as part of an international surgical course.MethodsEssential Skills in the Management of Surgical Cases (ESMSC) course recruits medical students from European Union (EU) medical schools. Students are asked to suture the dura mater in an ex vivo swine model, of which the first suture completed was assessed. Questionnaires were distributed before and after the module, eliciting tremor risk factors, self-perception of tremor and anxiety. Johnson O’Connor dexterity pad was used to objectively measure dexterity. Direct Observation of Procedural Skills (DOPS) was used to assess skills-based performance. Anxiety was assessed using the Westside Test Anxiety Scale (WTAS). Tremor was evaluated by four qualified neurosurgeons.ResultsForty delegates participated in the study. Overall performance decreased with greater subjective perception of anxiety (p = 0.032, rho = − 0.392). Although increasing scores for tremor at rest and overall WTAS score were associated with decreased performance, this was not statistically significant (p > 0.05). Tremor at rest did not affect dexterity (p = 0.876, rho = − 0.027).ConclusionsPhysiological tremor did not affect student performance and microsurgical dexterity in a simulation-based environment. Self-perception of anxiety affected performance in this module, suggesting that more confident students perform better in a simulated neurosurgical setting.
