Radiotherapy alone and with concurrent chemotherapy for nasopharyngeal carcinoma: A retrospective study.

We sought to evaluate clinical outcomes and toxicities of radiation therapy (RT) alone compared to RT with concurrent chemotherapy (CCT) for nasopharyngeal carcinoma (NPC) treatment.We conducted a retrospective review of consecutive patients with biopsy-proven nonmetastatic NPC who underwent RT at our institution. From May 2001 to April 2015; 62 newly diagnosed NPC patients were treated with three-dimensional conformal radiotherapy (3D-CRT) or intensity-modulated radiotherapy (IMRT) with or without CCT. The patients were classified as follows: 8% stage I, 15% stage II, 32% stage III, and 45% stage IVA/IVB. A total of 76% of tumors were World Health Organization types II or III. Acute and late toxicities were graded according to the Common Terminology Criteria for Adverse Events version 3.0. Overall survival (OS), progression-free survival (PFS), locoregional progression-free survival (LRPFS), and distant metastasis-free survival (DMFS) were analyzed.The median follow-up period for living patients was 53 months. The median actual delivered dose was 70 Gy with a range of 28 to 70 Gy in fraction sizes of 2 Gy. The estimated 5-year OS, PFS, LRPFS, and DMFS rates were 72.7%, 59.8%, 77.9%, and 84.2%, respectively. The use of CCT was a predictive factor of significantly better OS and PFS, whereas stage IV was a significant predictor of poor OS and PFS. The most severe acute toxicities included Grade 3 mucositis in 56% and Grade 3 dermatitis in 8%. Subset analysis revealed that Grade 2 xerostomia was significantly lower in the IMRT (23%) group than in the 3D-CRT (52%) group (P = .02).RT yielded favorable outcomes. CCT was associated with longer PFS and OS than RT alone.

Treatment of Ramsay-Hunt's syndrome with multiple cranial nerve involvement and severe dysphagia: A case report.

Ramsay-Hunt's syndrome (RHS) is a disorder characterized by facial paralysis, herpetic eruptions on the auricle, and otic pain due to the reactivation of latent varicella zoster virus in the geniculate ganglion. A few cases of multiple cranial nerve invasion including the vestibulocochlear nerve, glossopharyngeal nerve and vagus nerve have been reported. However, there has been no report about RHS with delayed onset multiple cranial nerve involvement causing severe aspiration, and a clinical course that improved after more than one year of dysphagia rehabilitation and percutaneous endoscopic gastrostomy (PEG). Here, we report on a 67-year old male with delayed onset swallowing difficulty after 16 days of RHS development.

A case report of life-threatening acute dysphagia in dermatomyositis: Challenges in diagnosis and treatment.

Although dysphagia is a known complication of dermatomyositis, sudden onset of dysphagia without the notable aggravation of other symptoms can make the diagnosis and treatment challenging.

Microsurgery for patients diagnosed with neurofibromatosis type 2 complicated by vestibular schwannomas: Clinical experience and strategy for treatments.

Most patients diagnosed with neurofibromatosis type 2 (NF2) have bilateral vestibular schwannomas (VS). Through reviewing surgical method and clinical outcomes, we tried to find out a strategy for treatments in NF2 patients with VS.We retrospectively reviewed patients diagnosed pathological NF2 and have had microsurgery (MS) for VS in the PLA Army General Hospital. Seventeen patients were included from January 2000 to December 2016. Fifteen patients had progressive hearing impairment, and 7 ears were totally deaf. Computed tomography and magnetic resonance imaging were used for preoperative and postoperative evaluation. House-Brackmann (H-B) classification was used to evaluate facial function, and the hearing outcome was classified according to American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) hearing classification system. The outcomes included functional hearing, facial function, and complications.In the 17 patients, 9 were men, and the mean age was 27.2 years old. The mean duration of disease was 38.4 months. Twenty-six VS were excised. Nine patients with bilateral VS and unilateral surgery had repeated surgery for the contralateral tumor after 3 to 12 months. The hearing preservation rate was 41.6%. In the 26 excisions for VS, 24 had intact facial nerve. In the other 2 tumor excision, damaged facial nerves had head-to-head adhesion using biological fibrin glue. The rate of facial nerve function preservation was 60%. No mortality or major complication was reported. The follow-up time ranged from 11 to 78 months with a mean value of 39 months.MS is an effective treatment for NF2 patients with VS. The operation for bilateral VS should be staged according to tumor size and bilateral hearing function. However, methods on how to preserve functional hearing and facial function remain the issue. Further randomized controlled studies are needed to find out a better treatment for NF2 patients with VS according to the overall condition.

Stable knockdown of ZBTB7A promotes cell proliferation and progression in nasopharyngeal carcinoma.

Although high expression of ZBTB7A is positively relative to metastasis in nasopharyngeal carcinoma (NPC) patients, the association between its low expression and metastasis of NPC remains unclear. The present study aimed to definitely identify the association.

Speech-language therapy program for mouth opening in patients with oral and oropharyngeal cancer undergoing adjuvant radiotherapy: a pilot study.

Purpose Assess the effectiveness of an orofacial myofunctional therapeutic program in patients with oral or oropharyngeal cancer submitted to adjuvant radiotherapy through pre- and post-program comparison of maximum mandibular opening. Methods Prospective study involving five adult patients and five elderly patients postoperatively to oral cavity/oropharynx surgery who were awaiting the beginning of radiotherapy or had undergone fewer than five treatment sessions. The study participants had their maximum jaw opening measured using a sliding caliper at the beginning and end of the program. Two mobility exercises and three mandibular traction exercises were selected and weekly monitored presentially for 10 weeks. Descriptive data and pre- and post-therapy comparative measures were statistically analyzed using the Wilcoxon test. Results Ten patients (two women and eight men) with mean age of 58.4 years, median of 57.0 years, completed the therapeutic program. They presented mean maximum mandibular opening of 31.6 ± 11.7 and 36.4 ± 8.0 mm pre- and post-therapy, respectively (p =0.021). Conclusion The proposed orofacial myofunctional therapeutic program increased the maximum jaw opening of patients referred to adjuvant radiotherapy for oral cavity or oropharynx cancer treatment.

Extensive tumor of the skull base: sphenoid sinus adenocarcinoma.

We report a rare case of adenocarcinoma of the sphenoid sinus manifesting as extended skull base tumor. The patient included in the study was a 42-year old woman presenting with unilateral right symptomatology consisting of nasal obstruction, diplopia and hemifacial neuralgias. Clinical examination showed paralysis of the cranial nerve pairs V and VI. Brain scanner showed voluminous heterogeneous sphenoid and clival mass reaching the right cavernous sinus, with a peripheral tissue component at the level of the sphenoid sinus. Biopsy was performed under general anesthesia, through endonasal sphenoidotomy approach. Histological examination showed non-intestinal adenocarcinoma. The patient died due to impaired general condition occurred during examinations. Skull base adenocarcinomas mainly occur in the ethmoid bone. Sphenoid origin is exceptional. Radiological appearance is not specific and suggests malignancy. Diagnosis should be suspected in patients with aggressive tumor, even when it occurs in the midline skull base.

An unusual cause of high dysphagia: schwannoma of the preepiglottic space.

Schwannomas are well encapsulated mesenchymal tumors of peripheral nerves, with slow growth. The laryngeal schwanomma is exceptional, we present a case not described in the literature of shwannoma in the pre epiglottic space. A 50-year-old woman, who had a history of foreign body sensation for 4 years ago, progressing to high dysphagia and hoarseness. Direct laryngoscopy in suspension demonstrated a regular submucosal mass in the supraglottic space, reducing pharyngo-laryngeal space. CT and MRI concluded with a benign tumor of the preepiglottic space. External surgical excision was performed and a primary tracheotomy was required. The histological examination with an immunochemical study confirmed a benign schwannoma. There was no complication postoperatively. The outcome was excellent after 2 years of follow-up.

Asymptomatic intrathyroidal pyriform sinus fistula mimicking thyroid cancer: A case report and literature review.

There have been many reports of non-thyroidal lesions which can be mistaken for thyroidal lesions on ultrasound (US) examination. However, it is not known that pyriform sinus fistula (PSF) can manifest as an incidental thyroid nodule and cause serious complication on fine-needle aspiration (FNA).

Brain abscess caused by chronic invasive actinomycosis in the nasopharynx: A case report and literature review.

Actinomycosis is a rare anaerobic, gram-positive bacterial infection caused by Actinomyces, which is part of the normal flora in the oral cavity and respiratory and female genitourinary tracts. The cervicofacial area is the most common site of involvement, and involvement of the central nervous system is rare.

Auricular sporotrichosis. Atypical case report simulating bacterial cellulitis.

Sporotrichosis is the most common subcutaneous or implantation mycosis in Mexico. The case of a preauricular cutaneous-fixed sporotrichosis simulating atypical bacterial cellulitis is reported in an elderly patient with no history of trauma. The biopsy showed a suppurative granuloma with scarce yeast. Sporothrix schenckii was identified in the culture and confirmed by molecular biology. She was treated with itraconazole and a clinical and mycological cure was obtained. The case of atypical presentation is presented, coming from a semi-arid zone with extreme weather.

Fiberoptic bronchoscopic treatment of blood aspiration and use of sugammadex in a patient with epistaxis: A case report.

In patients with oropharyngeal and nasopharyngeal bleeding, blood aspiration can make airway management difficult and lead to severe pulmonary complications.

Multiple metastases of clear-cell renal cell carcinoma to different region of the nasal cavity and paranasal sinus 3 times successively: A case report and literature review.

Distant metastasis of clear-cell renal cell carcinoma (ccRCC) to the nasal cavity and paranasal sinus is rare. Endoscopic biopsy used to be performed for diagnosis when it is difficult for complete resection due to intense bleeding during surgery. According to previous literature, the outcomes of metastasis after endoscopic surgery remain unclear.

Decreased postural control in people with moderate hearing loss.

Balance is a complex process that involves multiple sensory integrations. The auditory, visual, and vestibular systems are the main contributors. Hearing loss or hearing impairment may induce inappropriate postural strategies that could affect balance and therefore increase the risk of falling.The aim of this study was to understand whether hearing loss could influence balance, cervical posture, and muscle activation in the cervical region.Thirteen patients (61 ± 13 years; 161.8 ± 11.0 cm; 70.5 ± 15.9 kg) with moderate hearing loss (Right ear -60 ± 21 dB; Left ear -61 ± 24 dB) underwent: an audiometric examination, a postural examination (with open and closed eyes) through a stabilometric platform, a cervical ROM examination through a head accelerometer, and a sternocleidomastoid electromyography (EMG) examination.A linear regression analysis has shown a regression coefficient (R) 0.76 and 0.69 between hearing loss and the posturographic parameters, on the sagittal sway, with open and closed eyes, respectively. The combination of frontal and sagittal sway is able to explain up to 84% of the variance of the audiometric assessment. No differences were found between right and left hemibody between the audiometric, posturographic, cervical ROM parameters, and in EMG amplitude. ROM and EMG parameters have not shown any significant associations with hearing loss, for both right and left head rotation.Hearing loss is associated to increased posturographic measures, especially the sagittal sway, underlining a reduced postural control in people with hearing impairments. No association was found between the heads posture and neck activation with hearing loss. Hearing loss may be associated with an increased risk of falls.

Reorganization of central cross-model pattern after auditory deprivation and cortical reconstruction following cochlear implantation.

The auditory nervous system has a rapid development period after birth, if there lack enough sensory(auditory) stimulation during this period, there should be a serious and negative impact on the growth and development of auditory center. In the auditory deprivation persist in the critical period, the auditory and visual cortex should be in cross-model reorganization and reorientation of cortical function. Cochlear implantation, especially intervention in the younger age, could excite the auditory cortex, and continuous stimulation to the cerebral cortex can promote the adaptation and reconstruction of auditory function. Speech and language skills can be developed by the synergistic effect of multiple sensory modalities.

Application of multiple acoustic immittance tests in evaluation of middle ear function in infants.

Evaluation of middle ear function in infants is the key to distinguish sensorineural hearing loss and conductive hearing loss, and acoustic immittance test is the routine audiological evaluation of middle ear function.Because of the characteristics of middle ear in infants, middle ear examination parameters of adults are not suitable for infants. This article reviewd the current multiple acoustic immittance methods for detecting middle ear function in infants, and summarized the advantages and disadvantages of these methods.

Characteristics of early hearing impairment in patients with diabetes mellitus.

The early hearing loss in diabetic patients is not easy to be perceived, therefore, comprehensive and complete audiological examination is necessary. At present, hearing loss in diabetes patients characterized by high frequency decline, some of the examination for high frequency hearing loss such as speech audiometry and extended high frequency are applicated. In addition, electrophysiological techniques have also been rapidly developed in animal experiments. This review summarized the audiological characteristics in diabetes patients and progress in animal experiments, which provided the basis for early diagnosis and early treatment of hearing loss in diabetes mellitus.
