Yersinia enteritis may present with alarming gastrointestinal manifestations. The aim of this study was to review the cases of children admitted to a general hospital with a preliminary diagnosis of surgical nature and subsequently proven to be infected by Yersinia enterocolitica. All cases of children aged less than 14 years with stool cultures positive for Y. enterocolitica during the 12-year period January 1993 through December 2004 were analyzed. Y. enterocolitica was isolated from the stools of 71 children with gastrointestinal manifestations; 27 children were treated as outpatients and 44 were hospitalized. Six were admitted to the Pediatric Surgery Department (13.6% of the total hospitalizations and 8.4% of all Y. enterocolitica cases). Four of the Pediatric Surgery patients presented with abdominal pain and right lower quadrant tenderness. The preliminary diagnosis of appendicitis was excluded during hospitalization and none of them underwent appendectomy. The other two children were admitted for vomiting initially attributed to a preceding head injury and for diarrhea and a perianal abscess. Two children were given antibiotics and all had an excellent outcome. Y. enterocolitica enteritis manifestations can infrequently mimic appendicitis or other surgical conditions but should remain in the differential diagnosis of children presenting with an acute abdomen.

Acute appendicitis is the most frequent disease in children population that requires an urgent surgical intervention. Only 2% of operated children belong to the group younger than 3 years. Yet, 77% are school children. Appendicitis in young children is characterized by: atypical clinical course, late diagnosis, high percentage of perforations, and high level of mortality and morbidity rates. The commonest symptoms are: vomiting, undefined abdominal pain, and high temperature. Abdominal distention and diffuse abdominal tenderness are the most frequent signs during examination. Our analysis (1991-2000) included all patients younger than 3 years who were hospitalized in Clinic for Pediatric Surgery Nis with diagnosis of the acute appendicitis. Out of 2533 patients with disease, 58 (2.3%) were younger than 3 years, 23 were girls (39.7%) and 35 were boys (60.3%). Perforated appendicitis was found in 55 (94.8%) of 58 children. Thirty five (60.5%) patients were previously treated. Complications developed in 36 (62.1%) cases: purulence (58.3%), dehiscence (22.3%), abdominal wall abscess (13.8%), and ileus (5.6%). Acute appendicitis is very specific condition that needs high attention by all doctors engaged in pediatric health care. Our recommendation is "to admit and observe" by using the physical examination in all suspected cases. Sometimes, even sedation may be used for better palpation results.

Appendicitis can usually be diagnosed on completion of a history and physical examination (abdominal pain, vomiting, right lower quadrant tenderness and guarding), although laboratory evaluation with a urinalysis and white blood cell count can be of assistance. In the few cases where doubt remains, plain films of the chest and abdomen can be helpful. Whether and when further imaging is indicated remains controversial. We reviewed reports of studies published since 2003 in which the sensitivity and specificity of CT and sonography for diagnosing appendicitis were determined. Sonography had an average sensitivity of 87.1% and an average specificity of 89.2% in the nine studies reported during that period. The average sensitivity of CT was 90.8% in 11 studies during that period, and there was an average specificity of 94.2% in 10 studies. We also looked at data from 299 patients who underwent appendectomies at our hospital. Of the appendices removed, only 10.7% did not have appendicitis. In many cases, CT or US imaging data were available in the form of reports or images or both from outside institutions. CT and US images were also available from our institution when the diagnosis was in question. This is how patients present in the real world-with studies that might not be the best, might not have been indicated, and might not have images available for another interpretation. Among patients operated on with neither CT nor US images, 10.9% did not have appendicitis. Among those in whom US imaging had been performed, 11.1% were negative for appendicitis, and among those in whom CT had been performed, 9.7% were negative. Although these studies were necessary because they were performed in patients whose diagnosis was the most difficult, it is in every patient's best interest to have a thorough examination by a surgeon prior to having a CT scan.

We report 12 patients [5 males, mean age 28 years (SD 4.6)] presenting with clinical features suggestive of acute appendicitis who were later diagnosed as having dengue fever (DF). Seven were admitted to hospital by surgeons and then referred to physicians due to thrombocytopenia (one of them following appendicectomy). Five were admitted to medical wards and then referred to surgeons due to abdominal pain. The mean time from onset of fever to abdominal pain was 2.2 d (SD 0.9). Clinical features included: right iliac fossa tenderness in 12 patients, rebound tenderness in nine, vomiting in nine, erythematous rash in eight, arthralgia/myalgia in eight, headache in six, diarrhea in three and palatal petechiae in three. All patients had C-reactive protein <12mg/l, and DF was confirmed serologically. Leucocytopenia and thrombocytopenia occurred by the third or fourth day of illness in all patients. Seven had free fluid around the appendix on abdominal ultrasound. The mean duration of abdominal symptoms and signs was 1.8 d (SD 1.3). DF may present with features suggestive of acute appendicitis in dengue-endemic areas. A carefully obtained history, clinical examination and a full blood count done on the third or fourth day of illness may help to differentiate DF from acute bacterial appendicitis.

Abdominal pain is common feature of Henoch-Schonlein purpura, which may mimic appendicitis, leading to unnecessary laparotomy. Accordingly, the diagnosis must be confirmed by ultrasonography or computed tomography scan before laparotomy is performed. The authors report a case of simultaneous occurrence of Henoch-Schonlein Purpura and gangrenous appendicitis in an 18 year-old boy. The patient was admitted with abdominal pain, cramps, and mild dehydration. He also complained of small reddish purple on his lower limbs, bilateral knee pain, low-grade fever, as well as bloody stools. The symptoms subsided completely. Eight days later, he returned with nonbloody, nonbilious emesis, abdominal cramps, and right lower quadrant abdominal tenderness. Abdominal ultrasound evaluation was performed to rule out an intussusception but demonstrated appendiceal dilatation with a possible appendicolith without any evidence of intussusception. A laparotomy was undertaken, and appendectomy was performed for gangrenous appendicitis. Simultaneous occurrence of Henoch-Schonlein purpura and acute appendicitis is rarely observed. Clinical features of the patients may mislead the clinicians, resulting in delayed diagnosis or misdiagnosis. The use of ultrasonography and computed tomography scan would confirm the diagnosis before surgery.

Our study on acute appendicitis in adults aimed to report current data in Yaounde, Cameroon. This retrospective study included 323 patients, with 185 men against 138 women (sex ratio: 1.37). Mean age was 28.3 years old. Incidence was of 4.6%. Symptoms appeared within a delay of 3 to 4 days and consisted of the triad: abdominal pain (97.5%), vomiting (44%) and anorexia (39.9%). 99.7% of the patients presented with hyperthermia whereas defence on palpation in the right iliac fossa was noted in 307 patients. Rectal examination was evocative in 92.7% of the cases. Hypemeutrophilia was found in 84.9% of the patients. Plain abdominal radiography (PAR) orientated the diagnosis in 74.3% of cases; echography was very useful in abscesses (6,5%). 96.7% of the patients underwent surgery within an average time of 48 hours. McBurney incision was performed in 232 cases. Appendice in the inner latero caecal position was predominant in 243 cases. In seven cases (2.2%), appendice was normal; 2 Meckel's diverticula were discovered (0.6%). We carried out 309 anterograde appendectomies, 317 irvaginations of the appendicular root and 14 epiplooplasties. 302 histological exams were performed; catarrhal appendicitis were ranking first: 167 cases. Morbidity reached 14.2% dominated by sepsis (71.7%). The mortality rate was 0.6%. A better diagnostic approach together with a better sensitisation of the population may shorten surgical delays inducing a decrease of morbidity of acute appendicitis in Cameroon.

Abdominal pain is a frequent presenting symptom among HIV-positive patients seeking care at emergency departments. We report a case of a 45-year-old HIV-infected Hispanic man who presented with right lower quadrant pain accompanied by fever, decreased appetite, nausea, and vomiting. The results of a CT scan of his abdomen were normal with no evidence of appendicitis. A colonoscopy was performed and revealed an impacted pill in the appendiceal orifice. The pill was removed endoscopically, and pill impaction has not recurred.

A 19-year-old woman presented to the emergency department with intermittent and progressively worsening abdominal pain, nausea, and vomiting. A computed tomographic scan revealed findings consistent with distal small bowel obstruction of unknown etiology. In the operating room, a torsed and gangrenous Meckel's diverticulum with extension of ischemia to adjacent small bowel was discovered and immediately resected. Pathology confirmed the diagnosis of gangrenous Meckel's diverticulum. Torsion and gangrene of a Meckel's diverticulum is a rare complication and often presents with vague and poorly localized signs and symptoms. The preoperative diagnosis is often difficult and presumed to be appendicitis or small bowel obstruction of unclear etiology. Complications of Meckel's diverticulum should be considered in patients with lower abdominal pain and acute abdomen.

Right lower quadrant (RLQ) pain is a common complaint in children presenting at emergency departments. This study analyzed the etiologies of RLQ pain, and compared the clinical presentations, laboratory test results and imaging findings in patients with appendicitis with those in other groups of patients. We also investigated if active observation resulted in delayed diagnosis, to the detriment of patients. Medical records for the period January 2006 to July 2006 were reviewed for children (age < 18 years) who presented to the emergency department of one medical center, complaining of RLQ pain. Out of a total of 100 patients (age range: 2-17 years; mean: 11 years), 46 patients presented with only one symptom of RLQ pain, while 32 patients had >/= 2 associated signs or symptoms, including fever, nausea/vomiting, diarrhea, or rebound tenderness. Imaging studies, including abdominal sonography and/or computed tomography, were performed in 73 patients; 44 underwent surgery for presumed appendicitis and one received surgery for a right paraduodenal hernia. Eleven patients underwent surgery because of peritoneal signs, and eight because of persistent or aggravated RLQ pain. Postoperative pathologic examinations revealed 53 cases of appendicitis, six normal appendices, and other morbidities (1 perforated peptic ulcer, 1 pelvic inflammatory disease, 1 ovarian cyst, 1 diverticulitis, and 1 right paraduodenal hernia). Thirty-three patients were discharged after several hours of observation (range: 0.5-18 hours; mean: 4 hours), and three patients were admitted for further observations. All were discharged without operation. There were significant differences in the incidences of fever (p = 0.004) and rebound tenderness (p = 0.019), and in white cell counts (p < 0.001), neutrophil percentages (p < 0.001), and C-reactive protein levels (p < 0.001) between patients with appendicitis and patients with other causes of RLQ pain. Clinical signs and symptoms, laboratory tests, and imaging studies can be used to differentiate between the causes of RLQ pain. Patients without the classical features of appendicitis or peritonitis can be safely managed by active observation and repeated physical examinations.

Traumatic small bowel strictures secondary to blunt abdominal trauma are extremely rare, with few cases reported. Delayed ileal perforation as a result of a traumatic ileal stricture remains, to the best of our knowledge, unreported. We herein report a case of a 28-year-old polytrauma patient admitted following a high speed road traffic accident who developed abdominal pain, distension and vomiting. Despite serial computerized tomography (CT) scanning, the diagnosis remained unclear until eight weeks into his admission by which time he had developed pyrexia. A fourth CT scan at this time revealed a collection in the right iliac fossa suggestive of possible appendicitis. Subsequent laparotomy, however, revealed an ileal stricture with upstream small bowel dilatation and perforation into a chronic abscess cavity. The appendix was normal. The patient underwent resection of the strictured segment and end ileostomy. Our case highlights the potential pitfalls in managing polytrauma patients who develop abdominal symptoms and in particular, traumatic small bowel strictures. We would like to highlight the limitations of CT in making this diagnosis and the importance of having a high index of clinical suspicion, particularly in the presence of distracting injuries.
