    Surgical site infection (SSI) is a common complication in head and neck surgeries. The aim of this study was to assess the rate of, and risk factors for SSI following surgical procedures of the head and neck. The study population comprised 206 patients who underwent surgery of head and neck region in NTT West Osaka Hospital between 2009 and 2011. The incidence rate and risk factors were estimated by the chi-square test and a logistic regression analysis.
    SSI occurred in 22 cases (10.8%) of 203 patients. A broad range of putative risk factors was recorded in each patient and statistically analyzed to elucidate SSI related factors. Univariate analysis indicated that low BMI, diabetes mellitus, anemia, hypoalbuminemia, surgical wound classification, duration of operation, blood loss, left implants and preoperative radiotherapy were risk factors associated with SSI. Multivariate statistics revealed four independent risk factors: surgical wound classification (odds ratio (OR) 5.88, p=0.02), hypoalbuminemia (OR 11.48, p<0.01), duration of operation (OR 18.66, p<0.01) and left implants (OR 20.24, p<0.01). Thus, to achieve a reduction in SSI, we need to take care of not only the factors related with surgical technique such as the duration of the operation or left implants, but the preoperative nutrition status.

    Mumps infection is anecdotally believed to occur only once over a lifetime. However, in recent years, it has gradually come to be recognized among pediatricians that mumps reinfection is not a rare condition, and some criteria for the mumps reinfection have been proposed. One of the widely accepted criteria is levels higher than 25.8 IU/dl of serum IgG antibodies against the mumps virus and lower than 2.0 IU/dl of serum IgM antibodies. From July 2010 to June 2011, 45 patients with acute swelling of the major salivary gland (s) were enrolled into our survey of mumps reinfection in Tsuchiura Kyodo General hospital. Serum IgG and IgM antibodies against the mumps virus were measured at the initial visit. Ten cases were diagnosed as having primary infection with the mumps virus, while the other 10 cases were diagnosed as having reinfection with the mumps virus according to the criteria. The present study suggests that mumps reinfection is a common condition in patients with acute swelling of the major salivary glands in adulthood.

  • Long-term Effects of Tinnitus Retraining Therapy Involving Monaural Noise Generators

    We have previously reported on the effects of tinnitus retraining therapy (TRT) involving monaural noise generators (NGs) up to 24 months after the start of treatment (Eur Arch Otorhinolaryngol. 2013 Feb; 270 (2): 443-8.) but very few reports exist about the long-term effects of TRT for periods of over 2 years. The aim of this study was to report the effects of TRT involving monaural NGs more than 24 months after the start of treatment. Thirty-three patients with chronic tinnitus were included in this study. All received directive counseling and monaural NGs without any other combination treatment. Effects were evaluated with the Tinnitus Handicap Inventory (THI) at their final visits to our clinic (average 31 months after the start of treatment). The average THI scores significantly improved from 55.3±19.7 at baseline to 33.5±23.3 at their final visits. Seventeen patients (52%) improved by more than 20 points from the baseline. Eleven patients who were treated with TRT for more than 3 years were individually observed in a detailed manner. Some of them experienced aggravation of their symptoms after 2 years' successful treatments. This study suggests that, although TRT seems effective more than 2 years after the start of treatment, the clinical course of each patient can vary and we need to follow them periodically depending on their situations and symptoms.

    Mycotic pseudoaneurysm is a rare complication of deep neck infection. We report herein on a case of mycotic pseudoaneurysm of the external carotid artery following myelodysplastic syndrome and a peritonsillar abscess. The patient was a male in his 60s, who complained of a sore throat and swelling of the left side of his neck. CT scan of the neck showed a left peritonsillar abscess and a pseudoaneurysm of the left external carotid artery. To correspond to airway obstruction in the event that the pseudoaneurysm might rupture to the pharyngeal space, the patient was transferred to our hospital. Surgical management was not selected, since MRI taken just after the admission to our hospital demonstrated remission of the pseudoaneurysm by organization of the structure and decrease of the blood flow. An antibacterial drug and an antifungal drug, SBTPC and VRCZ, were administered to the patient, the inflammatory signs reduced and the size of the pseudoaneurysm gradually diminished without sequela. These findings strongly suggest the importance of controlling the initial neck infection by administration of appropriate antibacterial and/or antifungal drugs to avoid the expansion of the mycotic pseudoaneurysm. Furthermore, MRI was useful to assess the state of the lesion and to determine the way of management.

    In the treatment of adult patients with acute rhinosinusitis, it has been assumed that subjects over 65 years of age or living with children attending a day nursery, are at higher risk for infection with drug-resistant bacteria. However there are few reports which have discussed the relationship between those risk factors and adult patients with acute rhinosinusitis. I investigated the association between adult patients with acute rhinosinusitis living with children attending a day nursery and gender, ages, and frequency of detection of drug-resistant bacteria. From 2010 to 2012, a total of 598 adult patients with acute rhinosinusitis were enrolled. The majority of the study subjects were women, and the largest 10-year age group was 30-39 years. By sex, a greater proportion of the female subjects than the male subjects lived with children attending a day nursery. By age, the proportion of subjects who lived with children attending a day nursery was significantly higher in the 30-39-year age group than other age groups. Drug-resistant Streptococcus pneumoniae and ampicillin (ABPC) -resistant Haemophilus influenzae were detected at significantly higher rates in subjects with children attending a day nursery than in those without. There were no significant difference in drug-resistant bacteria detection between subjects over 65 years of age, and under 65 years. These findings suggested that living with children attending a day nursery is a risk factor and source of infection by drug-resistant organisms that may cause intra-familial infections of adult patients with acute rhinosinusitis. These results suggested we must ask adult patients with acute rhinosinusitis whether they are living with children attending a day nursery or not, when we plan their treatment strategy.
