Laryngotracheal reconstruction in total laryngotracheal transection

A case of laryngotracheal trauma [LTT] was brought to hospital in emergency. After securing airway, neck was explored and total laryngotracheal separation together with crushed anterior and posterior tracheal walls was found. Cricotracheal anastomosis and anterior tracheal wall was repaired with perichondrium lined rib graft. Recovery was good, required dilatation once without any serious postoperative complication in close follow-up

Choanal atresia treated with transpalatal approach

A case of unilateral choanal atresia [CA] presented in adulthood with unilateral nasal discharge and obstruction, and coloboma of right lower eyelid. Diagnosis of choanal atresia was made with 0o telescope and CT scan. It was treated surgically by transpalatal [TP] approach. Stent was kept for 6 weeks. Few adhesions developed, which were broken. There was no other complication in follow-up

Transmural migration of surgical sponge evacuated by defecation

The spontaneous defecation of the retained surgical sponge is very rare. Here, we report a case of retained surgical sponge that migrated into the colon and was evacuated by defecation

Effect of calcium and light on the germination of Urochondra setulosa under different salts / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Urochondra setulosa (Trin.) C.E. Hubbard is a coastal halophytic grass thriving on the coastal dunes along the Pakistani seashore. This grass could be useful in coastal sand dune stabilization using seawater irrigation. The purpose of this investigation was to test the hypothesis that Ca(2+) (0.0, 2.5, 5.0, 10.0 and 50.0 mmol/L) alleviates the adverse effects of KCl, MgSO(4), NaCl and Na(2)SO(4) at 0, 200, 400, 600, 800 and 1000 mmol/L on the germination of Urochondra setulosa. Seed germination was inhibited with increase in salt concentration with few seeds germinated at and above 400 mmol/L concentration. No seed germinated in any of the KCl treatments. Inclusion of CaCl(2) substantially alleviated the inhibitory effects of all salts. Germination was higher under photoperiod in comparison to those seeds germinated under complete darkness. Among the CaCl(2) concentrations used, 10 mmol/L was most effective in alleviating salinity effects and allowing few seeds to germinate at 1000 mmol/L KCl, MgSO(4), NaCl and Na(2)SO(4) solution.

Risk factors in inhalation of foreign bodies in trachea bronchial tree in children

192 children with inhalation of foreign bodies in tracheobronchial tree were analysed in order to establish risk factors associated with such accidents. Eighty percent cases, with boys exceeding girls, were between age 2-7 years. Commonest foreign bodies were betel nuts [33 percent], peanuts [30 percent], plastic whistles [15 percent] and orange seeds [9 percent]. Occurrence of inhalation was more during winter season with peanuts and orange seeds as inhalant objects at the top of the list. Incidence of inhalation while [mouthing] the objects occurred in 78 percent cases during playing: 28 percent cases, during talking: 13.4 percent during laughing: 14 percent cases while whistling and 2.6 percent Infants foreign bodies were pushed by other children

Role of nasal splints in prevention of postoperative nasal adhesions and associated morbidity

Two hundred and fifty patients were included in a prospective, controlled clinical trial to find out the effectiveness of intranasal splints in prevention of postoperative nasal adhesions. One group [125] had insertion of splints while the other group [125] did not. Associated morbidity was also assessed. The incidence [of formation] of nasal adhesions was 2% in splinted group as compared to 11.9% in the non-splinted group [p<0.05]. The patients who had multiple procedures were at higher risk of developing adhesions. The mean pain scores at pack removal and on 7th postoperative day were significantly high in splinted patients [p>0.001]. The rate of Vestibulitis was 12% in splinted patients as compared to 2.55% in non-splinted patients. The complications such as septal perforation, ulceration and posterior dislocation of splint were not significant. It is concluded that splints should be used in carefully selected high risk patients
