RESUMEN

NONE: Exploding head syndrome is a rare sleep disorder, characterized by an explosive feeling in the head, that occurs during the sleep-wake transition. Usually the attacks are painless, but the fear caused by the attack can result in awakening and insomnia when it is generated frequently. It has been suspected that exploding head syndrome is related to emotional stress, because most patients report stressful life situations in periods when attacks are intense and frequent. The benign character and good prognosis of exploding head syndrome are the most likely reasons why it has not become a subject of more extensive neurologic research. Moreover, most of the articles reported symptomatic episodes but a lack of objective physiologic examinations, such as polysomnography, and effective treatment. Here, we report two cases of exploding head syndrome with the attacks documented by polysomnography and our trial treatment.

RESUMEN

OBJECTIVE: Since reports on surgical results for pediatric obstructive sleep apnea (OSA) in Japan are insufficient for debate, this study aimed to evaluate the feature of Japanese OSA children and surgical result and document whether is obesity and affecting factor similar to non-Asian countries. METHODS: This is a retrospective study. A total of 242 children with OSA at the Department of Otolaryngology and the Good Sleep Center, Nagoya City University Hospital and the Toyohashi Mates Sleep Disorders Center were included in the study. All children underwent pre- and postsurgical polysomnography. OSA was defined as an apnea hypopnea index (AHI) 5 or greater. Pre- and postsurgical respiratory parameters were compared using paired T test. RESULTS: Normalization of breathing after surgery for OSA children was 40% with AHI < 2 and 85% with AHI < 5. Japanese OSA children are not as obese as OSA children in many non-Asian countries. However, the normalization of breathing as a result of surgery in Japanese OSA children does not differ much from non-Asian countries. CONCLUSION: Japanese pediatric OSA that is not normalized by surgery may be affected by factors other than obesity.

RESUMEN

BACKGROUND: Myoepithelial carcinoma (MEC) is a rare salivary gland tumor. Its long-term prognosis remains unknown because of the paucity of reported cases with long-term follow-up. Although some case series exist, the clinical features of MEC vary considerably depending on the site of origin. Therefore, accumulation of these rare cases is important. CASE PRESENTATION: Case 1: An 89-year-old man presented with a 10-year history of a mass originating from the right parotid gland and involving the neck. The mass grew rapidly for 3 months, reaching approximately 8 cm. There was no facial paralysis. MEC ex pleomorphic adenoma (PA) was suspected. Superficial parotid gland resection was performed in 2013; the tumor grade was pT3N0M0, and the resection margins were free of carcinoma. Because of several high-risk factors for metastasis (i.e., invasive carcinoma ex PA, high MIB1 index, and mutant p53 protein positivity), radiotherapy and chemotherapy were recommended as adjuvant therapy. Although the patient refused adjuvant therapy, he was recurrence-free at 36 months after surgery. Case 2: A 54-year-old woman presented with a >10-year history of a right submandibular mass, which grew rapidly for 1 year, reaching approximately 6 cm. Preoperative diagnosis was PA of the right submandibular gland. Submandibular gland resection was performed in 2013. Pathological analysis revealed invasive MEC ex PA, pT3N0M0; in addition, the carcinoma portion had an extra capsule and had invaded the platysma muscle close to the margin. An MIB1 index of 40 % and mutant p53 protein positivity indicated a high risk for metastasis. Additional resection and right neck dissection revealed no residual carcinoma. The patient refused adjuvant chemotherapy. One year after surgery, metastasis to the right pulmonary hilar node and both lungs were detected. Chemotherapy prevented recurrent growth of the lesion and extended survival. The patient was alive with cancer 30 months after the first surgery. CONCLUSIONS: High expression of the Ki67 labeling index might reflect prognosis of these cases. Chemotherapy for distant metastasis was effective, as expected. Further accumulation of cases and long follow-up data are needed to elucidate the pathophysiology and prognosis of MEC ex PA.

RESUMEN

OBJECTIVES: Posterior reversible encephalopathy syndrome (PRES) is a rare and acute disease with central nervous system symptoms. Without appropriate therapy, patients may exhibit a poor prognosis. PRES should be recognized as a possible problem during therapy for head and neck squamous cell carcinoma (HNSCC). METHODS: A 56-year-old female developed PRES during combined modality therapy for HNSCC. On the fourth day after surgery and following chemoradiotherapy, PRES developed with a sudden visual disorder, followed by headache located at the back of the head and convulsions accompanied by impaired consciousness. We diagnosed PRES based on the clinical manifestations and magnetic resonance imaging data. RESULTS: The patient recovered from PRES by appropriate treatment. CONCLUSION: This is the first case report of PRES developed during treatment for HNSCC. Masked by other cerebrovascular disorders, more cases of PRES could exist than usually expected; therefore, we should consider PRES as a differential diagnosis for central nervous system disorders developing during high-intensity therapy.

RESUMEN

Cytomegalovirus (CMV) is a common opportunistic infection in immunosuppressive patients. One of the organs often involved is the gastrointestinal tract, but the pharynx, especially hypopharyngeal involvement, is rare. In this report, we present a case of a 61-year-old male compromised host, admitted to the hospital for the treatment of dermatomyositis, who presented with hypopharyngeal ulceration due to cytomegalovirus infection. Multiple deep ulcerative lesions with thick belaque, or with a protruding bony edge were observed in the adjacent areas in/around the hypopharynx, which repeatedly demonstrated exacerbation and remission in a relatively short period. The lesions developed acute bleeding and required emergency operative hemostasis. The ulcerations completely disappeared after the treatment with gancyclovir. We reviewed our case as well as other cases reported so far, and extracted the points we should be aware of when we encounter a case of hypopharyngeal ulceration based on cytomegalovirus infection; 1. acute bleeding, 2. paralysis of the vocal cords and subsequent breathing difficulty, 3. pharyngeal perforation.
