The heterodox nature of "Turban Pins" in foreign body aspiration; the central anatolian experience.

OBJECTIVE: The aim of this study is to determine the age and sex distribution and the nature of aspirated foreign bodies (FBs). We also compared Turban Pins (TP) with other FBs and discussed the extracting techniques. METHODS: From 1987 through 2006, 414 patients were managed and the records of the patients were retrospectively reviewed. RESULTS: Girls (56%) were influenced much more than the boys (44%). The median age was 4, however median age for girls and boys were 11 and 2, respectively. The 50% of the foreign body aspiration (FBA) were observed in the first years of life. There was also a great tendency to occur in the adolescent age group (32%), especially for girls. The most commonly aspirated foreign body was Turban pin (TP) (n=121) among 332 foreign bodies. FBs were successfully removed by rigid bronchoscopy in 94% of the patients. In patients who had a negative history (n=49), bronchoscopy was performed according to clinical suspicion, and it revealed foreign bodies in 41%. Thoracotomy was performed in eight (2.4%) patients. We had no mortality. CONCLUSIONS: These cases showed us that the type and age groups of FBA varies according to cultural conditions. We found that TP aspiration has different characteristics and it deserves a special attention. Suspicion is an important indication for bronchoscopy. We prefer rigid bronchoscopy because success rate is satisfactory.

Do absorbable sutures exacerbate presternal scarring?

We investigated cosmetic outcomes of the midline sternotomy incision. A randomized clinical trial was conducted in 60 patients who underwent surgery through a midline sternotomy incision. Patients were divided into groups A (n=30) and B (n=30). In addition, the incision line was also divided into 2 regions (upper and lower halves) in each group. In group A, the upper half of the skin was closed with absorbable 4-0 braided polyglycolic acid sutures (Sentesorb, Boz; Ankara, Turkey), and the lower half was closed with 4-0 nonabsorbable monofilamentous polypropylene suture (Monoplene, Boz), and vice versa in group B. Scar width and height were measured and photographed at the 6th postoperative month. In both groups, the lower part of the incision showed inferior cosmetic results, regardless of the suture material (P <0. 05). On the other hand, the upper part of the incision in group A (the area of absorbable polyglycolic acid sutures) was significantly more hypertrophic. We conclude that monofilament nylon sutures diminish the risk of hypertrophic scarring, in comparison with absorbable sutures. In the lower half of the sternotomy scar, increased tension and relative mobility of the skin over the xiphoid process lead to inferior cosmetic results, regardless of the suture material used.

Tracheobronchial rupture: a considerable risk for young teenagers.

Tracheobronchial (TB) ruptures are ten times lower in children than in adults. Despite its rarity in the literature, we found that it is as common as in adults in our series. We investigated TB ruptures in childhood regarding age, trauma presentation, injury localization and treatment options. From 1994 through 2001, eight children (six male, two female) were admitted to our department with TB injury. All patients were healthy prior to trauma. The average and median ages were 9.8 and 11, respectively. All patients except one (iatrogenic) were suffering from blunt thoracic trauma. There were seven main bronchial (five right, two left) and one tracheal wounds. Six of the ruptures were circumferential. Urgent (n=6) and delayed (n=2) thoracotomies were performed; 'end-to-end' anastomosis (n=4), pneumonectomy (n=2) and 'primary suturing' (n=2) were applied. We had no mortality. Main bronchus rupture was overlooked in two patients as one of them had almost totally normal clinical appearance, and the other one had negative endoscopic findings. Both of these patients were successfully operated within 3 months. Our limited experience showed us that these kinds of injuries threaten school age population as well. False negative bronchoscopic results increase when additional injuries accompany. TB ruptures should be always taken into consideration after blunt chest trauma. Early or late repair of the lesion should be decided depending on the patient's clinical course.
