Acute appendicitis in preschoolers: a study of two different populations of children

<p>Abstract</p> <p>Objective</p> <p>To assess the incidence and the risk factors implicated in acute appendicitis in preschoolers in our region.</p> <p>Methods</p> <p>Over a 7-year period, 352 children underwent appendectomy for suspected acute appendicitis. Of these, data for 23 children were excluded because no inflammation of the appendix was found on subsequent histology. Of the remaining 329, 82 were ≤ 5 years old (i.e., preschool children) and 247 were 5-14 years old. These two groups of children were further divided according to their religion into Muslims and Christian Orthodox: 43 of the children aged ≤ 5 years were Muslims and 39 were Christian Orthodox. A household questionnaire was designed to collect data concerning age, gender, type of residence area, living conditions, vegetable consumption, and family history of surgery for acute appendicitis as preschool children. The removed appendices were also assessed histologically for the amount of lymphoid tissue.</p> <p>Results</p> <p>Acute appendicitis of preschoolers developed more frequently in Muslims (39.4%) than in Christians (17.7%; <it>p </it>< 0.001). The lack of inside toilet facilities at home, overcrowded living conditions, living in rural areas, and the amount of appendix lymphoid tissue were significantly more frequent among the Muslim preschool children (<it>p </it>< 0.05), while there were no statistically significant differences between Muslim and Christian children with regard to gender, the family history of acute appendicitis, or the vegetable consumption (<it>p </it>> 0.05).</p> <p>Conclusions</p> <p>In our region, the percentage of preschool-aged Muslim children with acute appendicitis was remarkably high. One possible explanation for this finding could be the higher amount of lymphoid tissue in the wall of the appendix in Muslim preschool children together with their low standard of hygiene.</p

Omental infarction in an obese 10-year-old boy

Primary omental infarction (POI) has a low incidence worldwide, with most cases occurring in adults. This condition is rarely considered in the differential diagnosis of acute abdominal pain in childhood. Herein, we present a case of omental infarction in an obese 10-year-old boy who presented with acute abdominal pain in the right lower abdomen. The ultrasound (US) examination did not reveal the appendix but showed secondary signs suggesting acute appendicitis. The child was thus operated on under the preoperative diagnosis of acute appendicitis but the intra-operative finding was omental infarct. Since the omental infarct as etiology of acute abdominal pain is uncommon, we highlight some of the possible etiologies and emphasize the importance of accurate diagnosis and appropriate treatment of omental infarction

Treatment of hemangiomas in children using a Nd:YAG laser in conjunction with ice cooling of the epidermis: techniques and results

BACKGROUND: Hemangiomas are the most common type of congenital anomaly in childhood. Although many resolve spontaneously, intervention is required when their growth could damage vital adjacent structures. Various therapeutic approaches to childhood hemangiomas with different types of laser have been described previously. The objective of this study was to determine whether the cooling of the epidermis during irradiation of hemangiomas with a Nd:YAG laser prevents thermal damage and decreases the number of sessions required to treat these lesions. METHODS: Between 1993 and 2001, 110 patients aged 3 months to 4 years, with cutaneous hemangiomas were treated with a Nd:YAG laser. The lesion was cooled with ice prior to, during, and after the irradiation. During each session the laser beam passed through the pieces of ice. The laser power was between 35–45 W with a pulse length of 2–10 seconds. RESULTS: After 6 months of follow-up, from the first session of laser treatment, total resolution was obtained in 72 (65.5%) patients. A second or third session followed in 30 out of 38 patients in which, the initial results were good, moderate, or poor. The parents of the remaining eight children refused this second session and these patients excluded from the study Complications were seen in nine (8.8%) patients. One patient had postoperative bleeding which stopped spontaneously, while atrophic scars occurred in six (5.8%) patients, and hypertrophic scars in two (1.9%) patients. CONCLUSIONS: Nd:YAG laser irradiation in conjunction with ice protection of the epidermis produces good cosmetic results for the treatment of cutaneous hemangiomas in children, and decreases the number of sessions for treatment of these lesions

Prediction of High-Grade Vesicoureteral Reflux after Pediatric Urinary Tract Infection: External Validation Study of Procalcitonin-Based Decision Rule

BACKGROUND: Predicting vesico-ureteral reflux (VUR) 653 at the time of the first urinary tract infection (UTI) would make it possible to restrict cystography to high-risk children. We previously derived the following clinical decision rule for that purpose: cystography should be performed in cases with ureteral dilation and a serum procalcitonin level 650.17 ng/mL, or without ureteral dilatation when the serum procalcitonin level 650.63 ng/mL. The rule yielded a 86% sensitivity with a 46% specificity. We aimed to test its reproducibility. STUDY DESIGN: A secondary analysis of prospective series of children with a first UTI. The rule was applied, and predictive ability was calculated. RESULTS: The study included 413 patients (157 boys, VUR 653 in 11%) from eight centers in five countries. The rule offered a 46% specificity (95% CI, 41-52), not different from the one in the derivation study. However, the sensitivity significantly decreased to 64% (95%CI, 50-76), leading to a difference of 20% (95%CI, 17-36). In all, 16 (34%) patients among the 47 with VUR 653 were misdiagnosed by the rule. This lack of reproducibility might result primarily from a difference between derivation and validation populations regarding inflammatory parameters (CRP, PCT); the validation set samples may have been collected earlier than for the derivation one. CONCLUSIONS: The rule built to predict VUR 653 had a stable specificity (ie. 46%), but a decreased sensitivity (ie. 64%) because of the time variability of PCT measurement. Some refinement may be warranted

Local peritonitis as the first manifestation of Crohn′s disease in a child

Crohn′s disease (CD) can occur anywhere in the gastrointestinal tract from the mouth to the anus and sometimes it presents in a nonspecific manner. Herein we describe a case of local peritonitis as the first manifestation of CD in an 11-year-old girl, and the subsequent method of treatment

Operative and nonoperative management of children aged 13 years or younger with arterial trauma of the extremities

BackroundPrevious studies have suggested that open repair of arterial injuries in very young children often leads to less satisfactory outcomes. The aim of this study is to describe a decade’s experience in the management of pediatric arterial trauma of the limbs, with an additional specific objective to evaluate the long-term outcome of arterial traumas in preschool children treated conservatively.MethodsHospital charts were reviewed for all children aged ≤13 years with arterial trauma of the extremities who underwent operative or nonoperative treatment. Twenty-three children were located who had arterial traumas equally divided between the upper extremity (13) and lower extremity (10).ResultsThe method of treatment was either open surgical repair or medical treatment consisting of systematic heparin administration. In 11 of 12 school-aged children (>6 years; mean age, 10 years), open surgical repair was performed. In six of 11 preschool children (≤6 years; mean, 3.2 years) medical treatment was offered. Open repair was deferred in all children <2.5 years. Autologous vein interposition grafting was the most common surgical procedure and was performed in 10 patients. There were no deaths, and 87% limb salvage (21/23) was achieved. Two patients, both in the surgical arm, underwent lower limb amputation. The long-term outcome of those treated conservatively was excellent in all but one child, in whom minor limb-length discrepancy was detected.ConclusionSurgical repair can be performed in school-aged children as in adults. Surgical treatment of arterial injuries in neonates, infants, and those children <2.5 years old might best be deferred in ischemic but nonthreatened limbs. In a nonthreatened ischemic extremity in this age group, systemic heparinization is an alternative safe method of management. Limb loss is rare if distal Doppler signals are present; but as children grow, limb shortening is a threat. In preschool children, the risks of an open surgical repair must be weighed against any potential benefits
