“…The reasons for patients' self-induced pneumoparotid were conflicts with parents [7,96], as an excuse for not going to school [11,40,48,96], an adjustment reaction to adolescence [12,17,21], to gain attention [69], mental disorders [16,39,56,96], to escape duty [67,131], and to leave prison [111]. Causative wind instruments, including toy instruments, were trumpets [5,13,54], flutes [66,76], a clarinet [13], a horn [15], a tuba [74], a recorder [77], fanfare [64], and a paper trumpet [104]. Diseases inducing pneumoparotid included coughing attacks [18,38,51,96], nervous tic [6,32,55], obstructive sleep apnea syndrome [42,125], sneezing crisis [10], mental disorder [17], clearing nares during hay fever attack [20], head and maxillofacial trauma [46], and vomiting [100].…”
