Management of entrapped temporal horn: Literature review and operative technique for endoscopic fenestration.

CONTEXT: Entrapment of the temporal horn (TH) is rare condition that can lead to increased intracranial pressure, but there is no consensus on a standard treatment. The aim of this study was to conduct a systematic literature review of the reported cases of TH entrapment and describe our operative technique for endoscopic fenestrations of the lateral ventricle into the basal cisterns. METHODS: We searched the databases Pubmed and Google scholar to find all studies reporting cases of entrapped TH and the subsequent treatment. Additionally, we report two illustrative cases of endoscopic fenestration with a step-by-step description of our surgical technique. RESULTS: Twenty-nine studies with a total of 67 patients were included in the analysis. The mean age was 36.5 years (SD± 21.9), and the female-to-male ratio was 1.5. The most frequent cause of TH entrapment was post-surgical scarring after tumor surgery (n= 30), and the most commonly reported treatment modality was endoscopic fenestration of the TH (n = 14). We observed an increasing use of endoscopic fenestration over time. CONCLUSION: Entrapped TH is a rare condition often requiring surgical treatment. Neuronavigation-guided endoscopic fenestration of the ventricle into the basal cisterns appears to be a safe, efficient, and device-free technique that has gained importance over the past years.

Paragangliomas of the spine: a retrospective case series in a national reference French center.

INTRODUCTION: Primary paragangliomas (PG) of the spine are extremely rare entities. The present study reviews our experience over a period of 30 years. METHODS: This is a retrospective, single center, observational study. Patients surgically treated for a spinal PG with confirmed anatomopathological diagnosis were included. The McCormick classification was used as a reference for clinical evaluation. Follow-up MRI and clinical assessment took place at 6 weeks, 3 months, 6 months, and 1 year after surgery and on yearly basis after. RESULTS: Six cases have been operated in our institution. The mean age was 37.8 (median 35.5, 30-53). The mean follow-up period was 9.6 years (median 9.5, 1-23). Preoperative duration of symptoms varied between a few hours to 4 years. Low back pain was most common sign. One presented with hemorrhage and acute onset of paraplegia. All patients underwent single surgery, with the exception of one case, which had two surgeries on the same anatomical site and a third surgery on another location of the same tumor type. Preoperatively, McCormick scale was I in four cases, and II and IV in one case, respectively. Postoperatively, all patients in McCormick I retained the same class; one patient in McCormick II passed to McCormick III; the case in McCormick IV recovered to McCormick II. Five of eight surgeries achieved total resection, while two surgeries accomplished a partial microsurgical excision and one a gross total resection. Three patients had spinal leptomeningeal dissemination. Two of them benefited from extended spine radiotherapy, while the other of a "wait-and-scan" policy. Spinal leptomeningeal dissemination was stable in all patients at last follow-up. CONCLUSION: We consider surgery as primary treatment in all PG. In our experience, preoperative diagnosis is difficult and caution must be taken to perioperative course in these cases. We do not routinely perform postoperative radiation if there is a residual tumor. We regularly perform clinical and radiological follow-up, so as to be able to document recurrent cases, which have been reported even up to 30 years after primary surgical excision.

Sports injuries and illnesses during the second Asian Beach Games.

BACKGROUND: Prevention of sport injuries and illnesses is a focus for epidemiological surveillance. OBJECTIVES: To record and analyse all sports injuries and illnesses registered during the second Asian Beach Games. DESIGN: A descriptive epidemiological study using the International Olympic Committee Surveillance system to register injuries and illnesses during the second Asian Beach Games. METHODS: The second Asian Beach Games hosted 1132 athletes from 43 countries competing in 14 beach sports. All National Olympic Committees' physicians of the participating teams were invited to report all injuries and illnesses. In addition, medical officers at the different Olympic venues and the main Olympic village reported injuries and illnesses treated at the clinics on a daily basis. RESULTS: A total of 177 injuries were reported equating to an incidence rate of 156.4 per 1000 registered athletes. Tent pegging recorded the highest incidence of injuries with 357 per 1000 registered athletes. The most prevalent injuries were in the foot/toe with 14.1% of all reported injuries. The majority of injuries were incurred during competition (75.4%). In addition, the most common mechanism of injury was contact with another athlete (n=42, 23.7%) and combined sudden and gradual overuse contributed to 30% of the total injury burden. Furthermore, 118 illnesses were reported resulting in an incidence rate of 104.2 illnesses per 1000 registered athletes. The most affected system was the respiratory tract (39.1%) with infection being the most common cause (n=33, 38.0%). The incidence of injury and illness differed significantly among the 14 sports. CONCLUSION: The data indicate that the risk of injury from beach games is sport dependant. This means that any preventive measures have to be tailored for each discipline. Furthermore, the study showed that respiratory infections are the commonest illness in beach sports and therefore, event organisers should focus improving public health measures and hygiene awareness.
