Tongue pressure is reportedly associated with dysphagia. This study investigated relationships among characteristics of head and neck cancer, tongue pressure and dysphagia screening tests performed in patients with head and neck cancer during the acute phase after surgical resection. Fifty-seven patients (36 men, 21 women; age range 26-95 years) underwent surgical resection and dysphagia screening tests (Repetitive Saliva Swallowing Test, Water Swallowing Test, Modified Water Swallowing Test and Food Test) and pre- and postoperative measurement of tongue pressure at 5 time points (preoperatively, and 1-2 weeks and 1, 2, and 3 months postoperatively). Progression of cancer (stage), tracheotomy, surgical reconstruction, chemotherapy, radiotherapy and neck dissection were factors associated with postoperative tongue pressure. Data were analyzed by linear mixed-effect model, Spearman correlation coefficient and receiver operating characteristic (ROC) curve. Tongue pressure was significantly reduced 1-2 weeks after surgery, and recovered over time. Changes in tongue pressure were significantly associated with stage, radiotherapy and reconstruction. All screening tests showed a significant relationship with tongue pressure. Analysis of ROC and area under the effect curve suggested that a tongue pressure of 15 kPa can be used as a cut-off value to detect dysphagia after surgery for head and neck cancer. Our results suggest that tongue pressure evaluation might offer a safe, useful and objective tool to assess dysphagia immediately postoperatively in patients with head and neck cancer.

Post‐orgasmic illness syndrome (POIS) is a rare disease characterized by flu‐like symptoms persisting for 2–7 days after ejaculation. POIS has been chiefly attributed to allergic reactions to autologous seminal plasma. However, the exact pathophysiology remains unclear, and there is no effective treatment. We present the case of a 38‐year‐old man with a 10‐year history of recurrent episodes of flu‐like symptoms of 1‐week duration after ejaculation. The patient was diagnosed with irritating bowel syndrome because of fatigue, myalgia, and lateral abdominal pain. After starting infertility treatment and increasing the frequency of intercourse with his wife, the patient noticed these symptoms after ejaculation. Based on these episodes and symptoms, POIS was suspected. To diagnose POIS, a skin prick test and an intradermal test were performed using his seminal fluid, with the latter yielding a positive result. The patient was diagnosed with POIS, and treatment with antihistamines was continued. Due to its rarity, POIS is often underdiagnosed and underreported; however, the skin test can be a valid diagnostic tool. In this case, the intradermal test result was positive according to the broadly accepted criteria for POIS. Although quality of life is often severely affected in patients with POIS, a lack of a clear understanding of the pathogenesis of POIS prevents early diagnosis. To make diagnoses earlier, it is undoubtedly important to take a detailed medical history and perform skin allergy tests, although the latter requires further validation.
