Most patients with AR are currently treated with pharmacotherapy. However, knowledge gaps on the use of pharmacotherapy still exist among physicians, particularly in the primary care setting, despite the availability of guideline recommendations. Furthermore, it is common for physicians in the secondary care setting to express uncertainty regarding the use of new combination therapies like intranasal corticosteroid plus antihistamine combinations. Inadequate treatment leads to significant reduction of quality of life that affects daily activities at home, work, and school. With these concerns in mind, a practical consensus statement was developed to complement existing guidelines on the rational use of pharmacotherapy in both the primary and secondary care settings.Keywords: allergic rhinitis, pharmacotherapy, consensus, primary care, secondary care, Malaysia

The osteogenic potential of human adipose-derived stem cells (HADSCs) co-cultured with human osteoblasts (HOBs) using selected HADSCs/HOBs ratios of 1:1, 2:1, and 1:2, respectively, is evaluated. The HADSCs/HOBs were seeded on electrospun three-dimensional poly[(R)-3-hydroxybutyric acid] (PHB) blended with bovine-derived hydroxyapatite (BHA). Monocultures of HADSCs and HOBs were used as control groups. The effects of PHB-BHA scaffold on cell proliferation and cell morphology were assessed by AlamarBlue assay and field emission scanning electron microscopy. Cell differentiation, cell mineralization, and osteogenic-related gene expression of co-culture HADSCs/HOBs were examined by alkaline phosphatase (ALP) assay, alizarin Red S assay, and quantitative real time PCR, respectively. The results showed that co-culture of HADSCs/HOBs, 1:1 grown into PHB-BHA promoted better cell adhesion, displayed a significant higher cell proliferation, higher production of ALP, extracellular mineralization and osteogenic-related gene expression of run-related transcription factor, bone sialoprotein, osteopontin, and osteocalcin compared to other co-culture groups. This result also suggests that the use of electrospun PHB-BHA in a co-culture HADSCs/HOBs system may serve as promising approach to facilitate osteogenic differentiation activity of HADSCs through direct cell-to-cell contact with HOBs., (© 2015 Wiley Periodicals, Inc.)

As many as 31% of patients with nasopharyngeal carcinoma present with intracranial extension. Despite this high percentage, extension to the cerebellopontine angle is rare. The mechanism of tumor spread to the cerebellopontine angle is not completely understood. The most likely mechanism is direct extension to the skull base with involvement of the petrous apex and further extension posteriorly via the medial tentorial edge. We report the case of a 46-year-old woman with nasopharyngeal carcinoma who had been treated initially with chemoradiation and subsequently with stereotactic radiosurgery for residual tumor. One year later, she presented with an intracranial recurrence of the nasopharyngeal carcinoma in the cerebellopontine angle; the recurrence mimicked a benign tumor on magnetic resonance imaging. The tumor was ultimately diagnosed as an undifferentiated carcinoma of nasopharyngeal origin. She was treated with palliative chemotherapy.

Localized sphenoethmoid sinusitis in children is a rare occurrence. It is usually overlooked because of the misconception that the sinuses are not developed. We describe a case of localized acute sphenoid and right posterior ethmoid sinusitis that presented as right frontobasal subdural empyema and multiple deep cerebral abscesses. Morbidity from subdural empyema in children is high. Early diagnosis and treatment based on recognition that the etiology might involve the paranasal sinuses affects the overall prognosis.

Vincristine-induced vocal cord paralysis is a rare but serious complication. We report 2 patients with acute lymphoblastic leukemia who developed progressive stridor during induction chemotherapy. There were no clinical features of peripheral or autonomic neuropathy. Flexible laryngoscopy confirmed the diagnosis of bilateral vocal cord palsy; interestingly, the nerve conduction test revealed axonal motor neuropathy involving the median and common peroneal nerves in both patients. The first patient required prolonged ventilatory support necessitating unilateral cordectomy before extubation, whereas the second only required supplemental oxygen therapy. There was resolution of stridor in the first patient after cordectomy and gradual clinical improvement in the second. These cases illustrate that a high index of suspicion of vincristine-induced vocal cord palsy with prompt otolaryngology consultation for laryngoscopy is required in the diagnostic evaluation of a patient who has received vincristine.

A pyolaryngocele is an uncommon complication of a laryngocele that has become infected. We present a case of a pyolaryngocele that was probably due to repeated injections in the neck veins. The pathogenesis, clinical features and management are discussed in detail.
