The management of low-grade (grade II) oligodendrogliomas is still controversial, due to their rarity and long-term survival. According to recent WHO 2016 Classification of central nervous system tumors oligodendrogliomas are defined by the coexistence of molecular alterations, such as isocitrate dehydrogenase (IDH)1/2 mutations and 1p/19q codeletion. These tumors have better outcome and higher response to chemotherapy compared with diffuse astrocytomas.

The association of radiotherapy and procarbazine, lomustine (CCNU), vincristine chemotherapy in low-grade oligodendrogliomas is definitely superior over radiotherapy alone, and yields median progression-free survival and overall survival values exceeding by far 10 years. Chemotherapy alone yields results that are inferior compared with radiotherapy + procarbazine, CCNU, vincristine but may better preserve cognitive functions from radiotherapy-induced damage. Chemosensitivity of oligodendrogliomas is related to a high percentage of O6-methylguanine-DNA methyltransferase methylation and low expression of DNA repair genes. Recurrent defects in mismatch repair pathways may induce hypermutation and secondary resistance to temozolomide, but not to nitrosoureas.

Reoperation at progression following initial chemotherapy is increasingly adopted, thus allowing a further delay of radiotherapy. In the future targeting IDH1/2 mutations following incomplete surgery may represent a new innovative option.

Dysphagia is a debilitating, depressing and potentially life-threatening complication in cancer patients that is likely underreported. The purpose of this review is to critically synthesize the current knowledge regarding the impact of chemotherapeutic regimens on swallowing function.

Those patients with cancers involving the aerodigestive tract, head and neck cancer and oesophageal cancer are at highest risk of developing dysphagia. The most common dysphagia causing toxicity of chemotherapeutic agents is mucositis/stomatitis. The use of cisplatin is correlated with increased incidence of mucositis. Similarly, the addition of melphalan is also associated with worsening mucositis and dysphagia. In some cases of oesophageal cancer, thyroid cancer, metastatic lung or breast cancer the use of chemotherapy can improve swallow function as obstructive lesions are reduced.

There is limited literature regarding the role of chemotherapy in the development or treatment of dysphagia. Most dysphagia that occurs during cancer treatment is attributable to radiation or the synergistic effect of radiation and chemotherapy. Patients with disordered swallowing prior to treatment have the greatest risk of developing posttreatment dysphagia. Studies are needed to determine whether acute inflammation associated with oropharyngeal mucositis predisposes for late dysphagia.

Swallowing is a vital function and the clearance of the pharynx by deglutition, which removes matter that could be aspirated, and the respiratory phase patterns associated with deglutition are important in protecting the airways and lungs against aspiration. This article reviews swallowing and respiratory phase patterns associated with deglutition during sleep and their implications for pathophysiology.

During sleep, swallowing is infrequent and absent for long periods. The deeper the sleep stage, the lower the mean deglutition frequency. However, in healthy younger adults, sleep-related deglutition is almost always followed by arrested breathing and expiration, reducing the risk of aspiration. Deglutition is extremely infrequent as well as absent for long periods in the aged. Sirtinol purchase Consequently, clearance of the pharynx and esophagus by deglutition was extremely reduced during sleep in the aged. Furthermore, respiratory phase patterns associated with deglutition displayed adverse patterns during sleep in the aged.

Due to the complexity of swallowing processes, many adverse health conditions can influence swallowing functions during sleep, especially in the aged. Sleep-related deglutition and respiratory phase patterns may adversely influence aspiration-related diseases such as aspiration pneumonia, especially in the aged not only with primary but also with secondary presbyphagia.

Many paediatric orbital subperiosteal abscesses (SPA) are effectively managed conservatively with systemic antibiotics, but surgical drainage is required in some patients. This review aims to summarize the current literature to determine predictors of surgical intervention.

Nearly all the data regarding this topic come from analysis of retrospective case series. There is consensus that large volume SPAs require surgical drainage; however, the cutoff for volume differs between studies. Proptosis more than 5 mm, superior location of SPA and patient age more than 9 years are also all factors that may predispose towards surgical treatment.

A conservative approach may be trialled in younger patients with medial, smaller volume SPAs. Larger volume SPA, presence of proptosis, superior location of SPA and patient age more than 9 years should lower the threshold for considering surgical intervention. Given that many studies have been retrospective, future studies should be prospective and specifically aim to determine a cutoff for SPA volume.
