Hyperammonemia Due to Empyema.

A 91-year-old woman was brought to our hospital with altered consciousness. Blood tests showed an increased ammonia level of 468 µg/dL and a normal liver function. Chest computed tomography showed massive right pleural effusion with loculation. We immediately performed chest drainage using two drainage tubes. The pleural effusate pH was 8.5. We diagnosed her with right empyema leading to hyperammonemia and initiated ampicillin/sulbactam therapy. However, she developed progressive renal failure and died on the third day. Empyema caused by urease-producing bacteria can lead to hyperammonemia. This is the first report of hyperammonemia due to empyema in the English literature.

Nurse intervention process for the thoughts and concerns of people with cancer at the end of their life: A structural equation modeling approach.

Over the last decade, the importance of Advanced Care Planning has been recognized in Japan. However, it is still difficult for healthcare providers and patients to verbalize how they want to spend the last days of their lives and what unfinished business they have left to accomplish. This study aimed to clarify how nurses intervened to assist patients with cancer at the end of life to express their thoughts and concerns. Twenty-four nurses were interviewed regarding how they intervened for patients' thoughts and concerns, and data were analyzed qualitatively using a modified grounded theory approach. A 25-item scale was selected, and the questionnaires, which included the scale, were distributed to nurses in general wards, palliative care units, and home visiting nurse services. A total of 1864 responses were analyzed. Factor analysis and structural equation model analysis were used, and three factors were identified: "assessment and intervention," "basic care," and "knowledge and communication," which led to the formulation of an intervention structure model for uncovering thoughts and concerns. These results indicate the importance of basic care and communication during interventions for patients.

An exploratory study of the factors related to mouth breathing syndrome in primary school children.

OBJECTIVE: Mouth breathing syndrome (MBS) is defined as a set of signs and symptoms that may be completely or incompletely present in subjects who, for various reasons, replace the correct pattern of nasal breathing with an oral or mixed pattern. It is important to identify the relevant factors affecting MBS in order to diagnose its cause since breathing obstructions can result from multiple factors. The purpose of this study is to clarify the relevant factors and the interrelationships between factors affecting MBS among children. DESIGN: We surveyed 380 elementary school children from 6 to 12 years in age. The questionnaire consisted of 44 questions regarding their daily health conditions and lifestyle habits and was completed by the children's guardians. A factor analysis was performed to classify closely related questions into their respective factors and to examine the strength of the correlation between the newly revealed factors. RESULTS: Twenty-six out of the 44 questions were selected, and they were classified into seven factors. Factors 1-7 were defined as "Incompetent lip seal", "Diseases of the nose and throat", "Eating and drinking habits", "Bad breath", "Problems with swallowing and chewing", "Condition of teeth and gums", and "Dry lips", respectively. There were also correlations between these factors themselves. CONCLUSION: MBS was categorized according to 7 major factors. Because Factor 1 was defined as "Incompetent lip seal", which was representative of the physical appearance of mouth breathers and correlated with other factors, we suggested that MBS should consist of 7 factors in total.
