RESUMO
INTRODUCTION: Postoperative antibiotics complement surgery in managing childhood-complicated appendicitis. However, there is limited evidence to guide clinicians on appropriate duration of therapy. A comparison cohort study was performed to determine whether tailoring duration of inpatient intravenous (IV) antibiotic therapy to patient response, assessed using a set of clinical criteria, leads to shortened hospital length of stay (LOS) without compromising patient outcomes. PATIENTS AND METHODS: Over a 6-month period, 47 children (aged 5-14 years) with complicated appendicitis were treated with postoperative IV antibiotics until each satisfied a set of bedside clinical parameters suggesting resolved intraperitoneal infection (core temperature < 38°C for 24 hours, tolerated two consecutive meals, mobilizing independently, requiring only oral analgesia). Complicated appendicitis was defined as the presence of generalized peritonitis, appendiceal perforation or gangrene, and/or abscess. Postoperative recovery parameters were prospectively recorded and compared with those of 47 historical control patients, matched by propensity scores, who received 5 days minimum of postoperative IV antibiotics. Sample size was determined by a priori power calculation based on reduction in LOS. Severity of postoperative complications was graded using the Clavien-Dindo system. RESULTS: Study group variables were comparable including patient demographics, duration of presenting symptoms, severity of presenting disease, preoperative antibiotics received, length of operation, seniority of primary surgeon, surgical approach taken, and intraoperative findings. The prospective cohort had a significantly shorter median LOS compared with the historical control cohort (5 vs. 6 nights, p = 0.010) while readmission rates and the incidence and severity of complications were similar, including incidence of postoperative intra-abdominal infections (6 vs. 8 cases, p = 0.562). CONCLUSION: Using bedside clinical parameters indicative of resolved intraperitoneal infection to tailor duration of postoperative IV antibiotics for children with complicated appendicitis shortens LOS without apparent compromise to patient outcomes.

BACKGROUND: We sought to determine the incidence of permanent hypopituitarism in a potentially high-risk group: young children after structural traumatic brain injury (TBI). METHODS: We conducted a cross-sectional study with longitudinal follow-up. Dynamic tests of pituitary function (GH and ACTH) were performed in all subjects and potential abnormalities critically evaluated. Puberty was clinically staged; baseline thyroid function, prolactin, IGF-I, serum sodium, and osmolality were compared with age-matched data. Diagnosis of GH deficiency was based on an integrated assessment of stimulated GH peak (<5 µg/liter suggestive of deficiency), IGF-I, and growth pattern. ACTH deficiency was diagnosed based on a subnormal response to two serial Synacthen tests (peak cortisol <500 nmol/liter) and a metyrapone test. RESULTS: We studied 198 survivors of structural TBI sustained in early childhood (112 male, age at injury 1.7 ± 1.5 yr) 6.5 ± 3.2 yr after injury. Sixty-four of the injuries (33%) were inflicted and 134 (68%) accidental. Two participants had developed precocious puberty, which is within the expected background population rate. Peak stimulated GH was subnormal in 16 participants (8%), in the context of normal IGF-I and normal growth. Stimulated peak cortisol was low in 17 (8%), but all had normal ACTH function on follow-up. One participant had a transient low serum T(4). Therefore, no cases of hypopituitarism were recorded. CONCLUSION: Permanent hypopituitarism is rare after both inflicted and accidental structural TBI in early childhood. Precocious puberty was the only pituitary hormone abnormality found, but the prevalence did not exceed that of the normal population.
