Acute abdomen in children due to extra-abdominal causes

Background: Acute abdominal pain in children is a common cause for referral to the emergency room and for subsequent hospitalization to pediatric medical or surgical departments. There are rare occasions when the abdominal pain is derived from extra-abdominal organs or systems. The aim of the present study was to establish the most common extra-abdominal causes of acute abdominal pain.
Methods: The notes of all children (1 month–14 years of age) examined for acute abdominal pain in the Accident and Emergency (A&E) Department of Alexandroupolis District University Hospital in January 2001–December 2005 were analyzed retrospectively. Demographic data, clinical signs and symptoms, and laboratory findings were recorded, as well as the final diagnosis and outcome.
Results: Of a total number of 28 124 children who were brought to the A&E department, in 1731 the main complaint was acute abdominal pain. In 51 children their symptoms had an extra-abdominal cause, the most frequent being pneumonia ( n  = 15), tonsillitis ( n  = 10), otitis media ( n  = 9), and acute leukemia ( n  = 5).
Conclusion: Both abdominal and extra-abdominal causes should be considered by a pediatrician who is confronted with a child with acute abdominal pain.

??Sudden and violent abdominal pain with comparatively fixed location should be clinical features in children with acute abdominal diseases. The constant development of system and organs in childhood makes it difficult for pediatricians to make correct diagnosis of pediatric acute abdomen. Complete inspection and particularly abdominal palpation and digital examination should be emphasized. Correct understanding of abdominal pain in children with acute abdominal diseases is of critical importance.     

Pott's puffy tumor in a 12‐year‐old boy

Pott's puffy tumor (PPT) is a rare complication of sinusitis characterized by subperiosteal abscess and osteomyelitis of the frontal bone. Early diagnosis and treatment is vital before it causes intracranial complications such as subdural empyema or brain abscess. Herein we describe the case of a 12‐year‐old patient who developed preseptal cellulitis and PPT, and was successfully treated with abscess drainage, sinus surgery and long‐term antibiotic therapy.     

Anaphylaxis induced by oral methylprednisolone in a 10‐year‐old boy

Corticosteroids are potent anti‐inflammatory and anti‐allergic agents used in the treatment of various inflammatory diseases, including allergic diseases. Allergic reactions caused by corticosteroids, however, have been reported. Among these, delayed reactions to topical steroids are more common, whereas immediate reactions to systemic steroids are rare. Herein, we report the case of a 10‐year old boy with methylprednisolone‐induced anaphylaxis, in which the patient had a positive oral challenge test result. Physicians should be aware of the possibility of anaphylaxis or other allergic hypersensitivity in response to corticosteroids.     

Osteoid osteoma mimicking Brodie's abscess in a 13‐year‐old girl

Osteoid osteoma is a solitary, benign lesion of bone causing significant nocturnal pain. Magnetic resonance imaging (MRI), computed tomography (CT), and bone scan are commonly used in this diagnosis. A case of osteoid osteoma of the distal femur mimicking chronic osteomyelitis with Brodie's abscess is reported and discussed. Initial radiographs and MRI showed a lesion of the distal femur consistent with subacute osteomyelitis with a Brodie's abscess. Because primary malignant tumor could not be eliminated, surgical biopsy was carried out. Histological examination showed a typical nidus consistent with the diagnosis of osteoid osteoma. Subacute osteomyelitis (Brodie's abscess) may be difficult to distinguish from other malignant or benign bone lesions as osteoid osteoma. CT usually is recommended as the best imaging procedure to identify the nidus and confirm the diagnosis. MRI also can be used for this purpose. Surgical biopsy remains mandatory for unclear lesions before deciding on appropriate treatment.
