Factors Affecting Resumption of Oral Intake of Food in Patients Undergoing Swallowing Rehabilitation.

In this study, we investigated for a period of 8 years, 884 patients who underwent swallowing rehabilitation in our hospital, and evaluated the factors affecting resumption of oral intake of food. We found that the number of patients undergoing swallowing rehabilitation in our hospital increased over time. Of the included patients, 82.8% were ≥70 years of age and men were more frequent than women (p=0.004). At the end of the rehabilitation, 56.3% patients' main nutrition route was oral. Most (60.5%) patients required <30 days of rehabilitation. We evaluated correlation between the states of patients at starting point of swallowing rehabilitation and the result of the rehabilitation. The patients having a desire for eating were significantly more successful in regaining oral intake of food than those without the desire (p<0.001) and those with desire unknown (p<0.001). We classified the patients as per the Japan Coma Scale into four groups: alert, 1 digit, 2 digits, and 3 digits; the 3-digit group was significantly less successful in resumption of oral ingestion compared to all other groups (p<0.001). Based on the activities of daily living (ADL), we classified the patients into four groups: supine position, possible to semi-sitting group (get-up more than 30°), possible to sit-up group, and possible more than transferring by oneself group. It was proved that the supine position group was significantly less successful in regaining oral intake of food compared to all other groups (p<0.001). Multivariate analysis showed that the strongest correlation for regaining oral ingestion was desire for eating (p<0.001), followed by ADL and level of consciousness. In conclusion, we found that the number of patients undertaking swallowing rehabilitation in our hospital is increasing, and that factors such as desire for eating, ADL, and level of consciousness significantly influence the resumption of oral intake of food.

Immunohistological Expression of p16INK4a is Commonly Present Both in Benign and Malignant Sweat Gland Neoplasias.

The expression of p16INK4a has been reported to be a significant marker for malignant transformation of epidermal tumors. However, little is known about sweat gland tumors. We examined the immunohistological expression of p16INK4a in benign and malignant sweat gland tumors. The ductal and acrosyringial portion of normal eccrine glands were positively stained with p16INK4a while it was negative in the normal epidermis. Moderate to strong expression of p16INK4a was found in 16 of 17 eccrine poromas, 4 of 5 hidradenomas, 3 of 3 syringocystadenoma papilliferums, 2 of 2 mixed tumors, and 3 of 3 syringomas. The p16INK4a expression was observed focally or diffusely in 4 of 4 porocarcinomas, 4 of 4 apocrine carcinomas and 12 of 17 extramammary Paget's diseases. We conclude that the p16INK4a expression is not a good marker for dictating malignant transformation of sweat gland tumors.

[A case of early Takayasu's arteritis with initial symptoms of carotidynia and fever].

We report herein on a 15-year-old girl with Takayasu's arteritis (TA) in the early pre-pulseless phase who presented with left neck pain and fever. Laboratory examination revealed a high level of C-reactive protein (CRP) and an elevated erythrocyte sedimentation rate (ESR). Findings of ultrasonography, computed tomography (CT), and magnetic resonance imaging and angiography (MRI, MRA) demonstrated a thickening of the left carotid artery but neither stenosis nor dilation of the large vessels. 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) after twenty days duration of fever revealed an accumulation of 18F-fluorodeoxyglucose not only in the left carotid artery but also the wall of the ascending aorta, aortic arch, thoratic aorta, and part of abdominal aorta, which led to the diagnosis of TA in the early pre-pulseless phase. The patient was treated with prednisolone resulting in a marked improvement in both the clinical symptoms and laboratory parameters within a couple of weeks. Stenosis of the left carotid artery was found in MRI, MRA following four months and a definitive diagnosis was reached. We suggest early diagnosis of TA may permit early treatment and improve the prognosis.

Expression of seven-in-absentia homologue 1 and hypoxia-inducible factor 1 alpha: novel prognostic factors of nasopharyngeal carcinoma.

Nasopharyngeal carcinoma (NPC) is an EBV-associated cancer. We analysed Siah1 expression as well as LMP1 and HIF1α expression by immuno-histochemical staining in 74 NPC biopsy specimens and found that the expression of Siah1 was significantly correlated with advanced tumour status and stage. Moreover, Siah1-positive and HIF1α-positive cases had significantly worse prognoses. The expression score for LMP1 was remarkably correlated with that of Siah1, whereas there was little correlation between LMP1 expression and the other markers evaluated. This is the first study to evaluate the pattern and clinical significance of Siah1 and HIF1α expression in NPC, and such an evaluation is valuable for identifying those patients at a high risk for a poor prognosis.

Concurrent intra-arterial chemotherapy and radiotherapy for advanced laryngeal cancer.

OBJECTIVES: An intra-arterial chemoradiotherapy regimen (RADPLAT) provides remarkable local control for head and neck cancer. This study evaluates the efficacy of a reduced RADPLAT protocol in patients who are candidates for total laryngectomy. METHODS: Forty-three patients with advanced laryngeal cancer were treated with 2 courses of intra-arterial cisplatin infusion (100 mg per body) during 40-Gy irradiation. The patients who showed a greatly diminished tumor received sequential irradiation. The patients with obvious residual disease received chemotherapy during the sequential irradiation. Poor responders, with less than 50% tumor reduction, underwent total laryngectomy. RESULTS: Forty-two patients completed the protocol. All surviving patients were followed for at least 3 years. Thirty-four patients were alive (80% of the supraglottic cases and 87.5% of the glottic cases). Local control was achieved in 27 patients (67.5% of the 11 glottic cases and 64.0% of the supraglottic cases). The glottic cohort showed better progression-free survival rates than did the supraglottic cohort (68.8% and 45.0%, respectively; p = 0.019). There were 2 cases of grade 3 neutropenia and 3 cases of grade 3 mucositis. No patients required tube feeding. One patient required tracheostomy 3 months after the completion of the treatment protocol. CONCLUSIONS: Concurrent chemoradiotherapy with a reduced dose of intra-arterial cisplatin is feasible for patients with advanced glottic cancer.
