A case of Horner syndrome diagnosed during the follow-up after major thoracic trauma is presented in this report. A 10-year-old boy was admitted to the emergency service with severe thoracic trauma with left clavicular and first rib fracture after a traffic accident. During the follow-up, myosis and ptosis were recognized in his left eye. Cranial tomography and neurological examination were all normal. The symptoms were thought to be caused by compression of the local hematoma to the cervical ganglia. After 30 days of conservative treatment with tube thoracostomies, he was discharged with his Horner syndrome. After 6 months of follow-up, the findings of Horner syndrome were found to be partially resolved. First rib fracture associated with Horner syndrome is very rarely seen in children, and only 2 cases were found in English-language literature. Our case seems to be the third reported case. Horner syndrome should be kept in mind in cases of first rib fractures. When head trauma is considered, as it can be mistaken with anisocoria, this knowledge may help the surgeon in differential diagnosis.

Pouch colon anomaly and high anorectal malformation are well-defined rare anomalies. The association of pouch colon anomaly with rectal atresia has previously been defined in only one case. In this study, a 2-day-old baby is presented with pouch colon anomaly without fistula and with rectal atresia. As a second case in the literature, this pathologic condition has been treated through the abdominotransanal route by using a single-stage endorectal coloanal pull-through. Being uncommon and having an important therapeutic approach, this case has been evaluated as worth presenting.

Background/Purpose The significance of spot urine 5–hydroxyindoleacetic acid (5-HIAA) levels in the early diagnosis of acute appendicitis (AA) is questioned. Methods Forty young, pigmented, male rabbits were divided into 4 groups. Groups are summarized as follows: group 1, control (n = 10); group 2, laparotomy, sham (n = 10); group 3, peritonitis with cecal ligation and puncture (n = 10); and group 4, experimental appendicitis (n = 10). Spot urine samples were obtained for 5-HIAA determination, and appendectomy materials were examined histopathologically and peritoneal fluid cultures were obtained after 12 hours in the study groups. The results were analyzed statistically with 1-way analysis of variance and Scheffe and Tukey's HSD tests. Results The mean 5-HIAA levels in the control group was 5.7 ± 0.6 mg/L, whereas it is 5.9 ± 0.9 mg/L, 6.6 ± 0.6 mg/L, 9.4 ± 0.9 mg/L in the sham, peritonitis, and appendicitis groups, respectively. The levels of 5-HIAA in the appendicitis group were higher than those in the other groups, which was statistically significant ( P Conclusions Spot urine 5-HIAA determination may be a practical, objective, and noninvasive method in the early diagnosis of AA. Because other radiological and laboratory tests can be insufficient, especially in the early period of AA, this test may be used effectively instead. Clinical studies are necessary for further conclusions.
