Intestinal injuries are pathologies frequently caused by toothpicks. In literature are reported serious damage to the cardiovascular system, lung and systemic fatal sepsis. In literature are also reported some deaths caused by delayed diagnosis. The authors report two cases of intestinal perforation by toothpick. Both patients had accidentally swallowed the toothpick. The clinical state was compatible with acute abdomen in a 59 year old psychopathic patient and acute appendicitis in a 27 year old patient. The aim of this paper is to emphasize the importance of a careful anamnesis for detecting the swallowing of a toothpick.

Although classic open surgery is simple, expeditious, and effective, it has some drawbacks, including wound sepsis, delayed recovery, operative difficulties, and possibility of unnecessary appendectomies for false appendicitis. The aim of this study was to assess the applicability and safety of laparoscopic appendectomy (LA) in a prospectively randomized trial. Seventy nonselective patients with suspected appendicitis were randomized to laparoscopic (n = 35, 17 male) or open appendectomy (n = 35, 15 male) and operated on an emergency basis. Operative findings, operating time, postoperative complications, and length of hospital stay were compared. We found that LA is associated with a shorter hospital stay, fewer postoperative complications, and better diagnostic accuracy, and it is recommended as the procedure of choice for the diagnosis and management of acute appendicitis.

Acute appendicitis is the most common condition requiring emergent abdominal surgery in childhood. The clinical diagnosis of acute appendicitis is often not straightforward because approximately one-third of children with the condition have atypical clinical findings. The delayed diagnosis of this condition has serious consequences, including appendiceal perforation, abscess formation, peritonitis, sepsis, bowel obstruction, and death. Cross-sectional imaging with ultrasonography (US) and computed tomography (CT) have proved useful for the evaluation of suspected acute appendicitis. There has been a great deal of variability in the utilization of these modalities for such diagnosis in the pediatric population. The principal advantages of US are its lower cost, lack of ionizing radiation, and ability to assess vascularity through color Doppler techniques and to provide dynamic information through graded compression. The principal advantages of CT include less operator dependency than US, as reflected by a higher diagnostic accuracy, and enhanced delineation of disease extent in a perforated appendix.

Nuclear factor-kappaB (NF-kappaB) has been demonstrated to regulate the transcription of target genes and stimulate inflammatory cytokine responses in a variety of inflammatory diseases. Preliminary studies have demonstrated that NF-kappaB is activated early in acute inflammation and sepsis and may serve as an indicator of clinical severity. The present study was designed to evaluate the degree of activation of NF-kappaB in patients with acute appendicitis and correlate activation with clinical extent of disease. Ten patients with acute appendicitis and five control patients (elective inguinal hernia repair) were evaluated by assaying NF-kappaB activity preoperatively and 12 to 18 hours postoperatively. Assaying of NF-kappaB was determined by binding activity for consensus probes in nuclear extracts from peripheral mixed white blood cells obtained by venous puncture. The bands of NF-kappaB activity from gel electrophoresis were quantified with a phosphor imager and reported as units of integrated intensity. The preoperative NF-kappaB activity was increased in all patients with appendicitis versus the controls [mean 151 (range 97-189) vs mean 50.3 (range 13.7-77); P < 0.0001]. The increased NF-kappaB activity also correlated with length of time of symptoms before operation. The patients who were symptomatic for less than 24 hours had an average NF-kappaB value of 103 (range 97-105) versus 171.4 (range 152-189) (P < 0.0001) in those who were symptomatic 24 or more hours. The NF-kappaB activity did not correlate with the white blood cell count. Postoperative NF-kappaB binding activity in the appendicitis patients dropped to minimal levels (mean 50.3), even lower than the control patients' baseline values (mean 55.6). Control patients demonstrated low baseline values preoperatively and a slight rise postoperatively [mean 50.3 (range 13.7-77) vs mean 100 (range 45-186)]. We conclude the following: (1) NF-kappaB binding activity is elevated in patients with acute appendicitis and correlates with symptoms longer than 24 hours. (2) This increased activity returns to baseline values within 18 hours after appendectomy. (3) Molecular indicators of inflammation may have a role in both staging surgical inflammatory conditions and predicting ultimate outcome.

The age peak for acute appendicitis is between 10 and 20 years. Although older persons more rarely develop appendicitis, in the group of over-45-year-olds the perforation and mortality rates are appreciably higher. The reason for this is the fact that in the elderly, the symptoms are often veiled, so that the diagnosis is delayed. A particular role in this connection is played by pain killers and non-specific findings. In particular, however, the commonly present co-morbidity in older patients with appendicitis often leads to recalcitrant infections, and not infrequently to sepsis with a potentially fatal outcome. For the establishment of the diagnosis, therefore, a careful physical examination and thorough history-taking, together with a comprehensive laboratory work-up is essential. Imaging procedures such as X-rays of the abdomen, ultrasonography and, where indicated, such further measures as a barium enema or a CT scan may help establish the diagnosis in patients with unclear clinical symptoms, and thus prevent perforation.

The aim of this study was to identify clinical parameters that may help distinguish periappendicitis from the more common clinical entity of acute appendicitis. Serosal inflammation of the appendix without mucosal involvement constitutes the condition known as periappendicitis. In most situations this is a sequel of extra-appendicular sepsis and is likely to benefit from treatment targeted to the underlying pathology. But the majority of these cases are initially treated for acute appendicitis as clinical distinction between the two conditions is difficult. In this study some commonly used clinical yardsticks have been analyzed with respect to their value in this subtle diagnosis. We reviewed 231 successive cases clinically diagnosed as acute appendicitis; of these 18 had histologically demonstrated periappendicitis. Eight parameters were studied: age, gender, temperature, white blood cell count, location and duration of pain, associated symptoms, and peritoneal signs. Significant statistical differences were found between the two groups with regard to pain location, pain duration, and the presence of peritoneal signs. It may be possible to suspect periappendicitis preoperatively with meticulous clinical assessment. This may be of value in avoiding missed nonappendicular pathologies.

Acute appendicitis is the most common acute abdominal condition that results in surgical intervention in childhood. The clinical diagnosis of acute appendicitis in children can be challenging. Approximately one-third of children with the condition have atypical clinical findings and are initially managed nonoperatively. Complications associated with delayed diagnosis of this condition include perforation, abscess formation, peritonitis, sepsis, bowel obstruction, infertility, and death. The use of cross sectional imaging has proven useful for the evaluation of suspected acute appendicitis in children. Both graded compression sonography and CT have been widely utilized in the imaging assessment of the condition. The principal advantages of sonography are its lower cost, lack of ionizing radiation, and ability to assess ovarian pathology that can often mimic acute appendicitis in female patients. The principal advantages of CT include less operator dependency than sonography as reflected by a higher diagnostic accuracy, and enhanced delineation of disease extent in perforated appendicitis.

Pasteurella pseudotuberculosis has been considered a widespread animal pathogen for many years, but only within the last decade has its capacity to cause human disease been recognized. Two forms of human disease have been established-acute septicemia and mesenteric lymphadenitis. Because mesenteric adenitis is frequently indistinguishable from acute appendicitis, blood serum was obtained from 66 consecutive patients who underwent operation for appendicitis and was examined for agglutinins to seven serotype strains of P. pseudotuberculosis. Agglutinins were obtained in 21.2% of this series. Titres of over 1/100 were found in three of three cases of mesenteric lymphadenitis, one of 11 with no apparent disease, and one of 46 with appendicitis. P. pseudotuberculosis was isolated from a lymph node in the latter case. Two to four follow-up samples of sera in each of these five cases had increasing and then decreasing titres, indicative of active disease. Titres of 1/15 or less were found in five of the cases of appendicitis, in one case of salpingitis, and in three with no apparent disease. The occurrence of these nine cases with low titres may be indicative of previous contact with the organism.Human infection with P. pseudotuberculosis is not unusual in the Edmonton region and is responsible for at least some cases of mesenteric lymphadenitis.

The authors describe a rare case report of a female patient with acute appendicitis, where the course was masked by gastroenteritis complicated with sepsis with a simultaneous course of imported infection with Salmonella type C (Kentucky). The attention is drawn to the fact that even such frequent abdominal emergency as appendicitis is, may cause diagnostic hesitations, if it is masked by a simultaneous alimentary infection. In spite of the application of a broad scope of examination methods a final decision of indication for laparotomy depends on clinical findings of the examining surgeon.

Acute appendicitis is the most common condition presenting with right lower quadrant pain requiring acute surgical intervention in childhood. The clinical diagnosis of acute appendicitis is often not straightforward and can be challenging. Approximately one-third of children with the condition have atypical clinical findings and are initially managed non-operatively. Complications usually result from perforation and include abscess formation, peritonitis, sepsis, bowel obstruction and death. Cross-sectional imaging with sonography and computed tomography (CT) have proven useful for the evaluation of suspected acute appendicitis in children. The principal advantages of sonography are its lower cost, lack of ionizing radiation, and ability to precisely delineate gynecologic disease. The principal advantages of CT are its operator independency with resultant higher diagnostic accuracy, enhanced delineation of disease extent in perforated appendicitis, and improved patient outcomes including decreased negative laparotomy and perforation rates.
