A three year prospective randomised study was undertaken to study the efficacy of three regimens of antimicrobial drug combinations in reducing postoperative wound sepsis in acute appendicitis. Group A--Metronidazole and gentamicin; Group B--Metronidazole and ciprofloxacin; Group C--Metronidazole and cefotaxime. Randomization was done by drawing from a set of sealed envelopes. Antibiotics were started preoperatively once a presumptive diagnosis of appendicitis was made, provided there was no history of prior antibiotic usage. For simple appendicitis (normal or inflamed) two more doses were given postoperatively. For complicated appendicitis, duration of antibiotic treatment was four days postoperatively. All antibiotics were given intravenously to avoid variations in bioavailability. Wound was inspected daily till discharge and at 30 days post operatively or earlier if the patient had symptoms of wound infection. A total of 128 patients completed the study. Eighty nine were simple appendicitis while the rest were complicated. Twenty one developed wound infection. Out of 21, 13 occurred in group A, 5 in group B and 3 in group C. Individually, the difference in infection rates between group A and group C patients with simple appendicitis was statistically significant. Infection rates in all other groups were not statistically different. Cefotaxime and metronidazole combination had the lowest wound infection rate. Hence it is recommended for antibiotic prophylaxis.

Pylephlebitis usually occurs secondary to infection in the region drained by the portal venous system. A most common antesecent focus of infection is diverticulitis and the most common blood isolate is E. coli (54%), followed by Proteus mirabilis (23%). Overall mortality is 32% and most of the patients who had died had severe sepsis prior to the initiation of antibiotic therapy. We describe a case of pylephlebitis which had appendicitis and consequent septic thrombosis of the portal vein and its branches, with dissemination of infection to the liver. The patient had recovered due to timely antibiotic treatment alone and resulted in complete resolution. Early diagnosis and treatment are basic to a favorable clinical course.

The prevalence of human immunodeficiency virus (HIV) infection is increasing in Singapore. The surgical experience, however, remains limited. A retrospective review of 13 HIV-positive patients requiring abdominal surgery within Singapore was done. There were 4 females and 9 males with age ranging from 21 to 44 years. Operations included appendicectomy, colectomy, splenectomy, intestinal bypass, gastrostomy and exploratory laparotomy. Pathologic findings directly related to HIV infection were found in two-fifths (5 out of 13) of these patients. A low CD4+ count or signs of full-blown acquired immunodeficiency syndrome (AIDS) were not associated with a higher likelihood of HIV-related pathology; neither did it preclude a successful outcome. There were 2 early postoperative deaths, both with HIV-related pathology. Five of our patients who survived their abdominal surgery died on follow-up with a median survival of 17 months. In patients with typical surgical problems, e.g. appendicitis and torsion of the ovary, early surgery allows for rapid recovery similar to normal surgical patients. Care of these patients is best provided by surgeons with experience and interest in this condition together with infectious diseases physicians. Even palliative surgery offers a respite from acute and often severe problems and improves the quality of life significantly. Two patients with AIDS presented with sepsis and diffuse abdominal tenderness. Subsequent laparotomy revealed only primary bacterial peritonitis. For patients with AIDS and non-localizing abdominal signs, alternative non-invasive diagnostic modalities such as computed tomographic (CT) scan should be considered.

Transvaginal ultrasonography (US) is a noninvasive, readily available imaging technique that has greatly enhanced diagnostic sensitivity and accuracy for both gynecologic and nongynecologic disease. High-frequency US probes placed in the vagina allow high-resolution assessment of all the pelvic viscera, including portions of the gut and urinary tract. In addition, they allow visualization of the peritoneum of the pelvic pouch and the pelvic side walls without interference from bowel gas or adipose tissue. Evaluation of these areas requires a modified US technique that includes the use of the highest-frequency probes with angulation of the transducer to allow assessment of the region of interest. In women of childbearing age, the similarity of symptoms in gynecologic and gastrointestinal tract disease in particular underscores the potential utility of transvaginal US, which may, for example, help differentiate appendicitis in a pelvic appendix from pelvic inflammatory disease. Transvaginal US may also help determine the correct course of therapy, thereby improving patient management. Other indications for transvaginal US include assessment for pelvic appendicitis and diverticulitis, rectal and perianal complications of Crohn disease, and ureteric and bladder calculi and tumors as well as evaluation of the anal sphincters in women with fecal incontinence. Transvaginal US is also superior to routine US in the detection and characterization of ascites and peritoneal disease. Transvaginal US examination should include the entire pelvic cavity and contents, especially in women at risk for pelvic sepsis or peritoneal disease.

C-reactive protein (CRP) was identified in 1930 and was subsequently considered to be an "acute phase protein," an early indicator of infectious or inflammatory conditions. Since its discovery, CRP has been studied as a screening device for inflammation, a marker for disease activity, and as a diagnostic adjunct. Improved methods of quantifying CRP have led to increased application to clinical medicine. In the emergency department (ED), CRP must be interpreted in the clinical context; no single value can be used to rule in or rule out a specific diagnosis. We conclude that CRP has limited utility in the ED. It may be a useful adjunct to serial examinations in equivocal presentations of appendicitis in those centers without ready access to computed tomography (CT) scan. It may be elevated with complications or treatment failures in patients with pneumonia, pancreatitis, pelvic inflammatory disease (PID), and urinary tract infections. In patients with meningitis, neonatal sepsis, and occult bacteremia, CRP is usually elevated. However, CRP has no role in diagnosing these clinical entities, and a normal CRP level should never delay antibiotic coverage.

The pathogenesis of peritonitis due to hollow-viscus perforation is currently accepted as being mainly based on the local and systemic release of pro- and anti-inflammatory mediators triggered by the presence of bacteria and bacterial products in the abdominal cavity. Therefore, treatment consists in focal restoration, intraoperative debridement and lavage, and postoperative measures such as drainage, continuous peritoneal lavage, or scheduled reoperation aiming at the removal of infectious agents from the peritoneal cavity to prevent persisting peritonitis and sepsis. In order to evaluate the pathophysiologic relevance of the bacterial and endotoxin load of the peritoneal exudate, we examined the peritoneal fluid of 20 children with perforated appendicitis for qualitative and quantitative analysis of bacteria, antibiotic concentrations, and endotoxin content. The time period ranged in 12-h intervals from intraoperatively to day 5. Eighteen of 20 fluid specimens (90%) showed endotoxin levels above 1.5 endotoxin units EU/ml (standard <0.1 EU/ml). The most common bacterial species isolated was Escherichia coli, mostly in high concentrations. Despite persisting high endotoxin concentrations and bacterial loads in the peritoneal cavity during the 5 postoperative days, the children recovered uneventfully and the systemic signs of infection disappeared rapidly. In conclusion, neither the bacterial nor the endotoxin load of the peritoneal cavity proved to be associated with the clinical course. Therefore, we hypothesize that during peritonitis compartmentalization of the focus of infection prevents further systemic reactions and ultimately leads to removal of the infectious agents by endogenous mechanisms. At least in peritonitis due to perforated appendicitis in children, adjuvant surgical measures in addition to appendectomy and intraoperative debridement are not necessary.

Surgery of the great veins inevitably began with the surgical treatment of injuries, often involving the femoral vein. Because of the famous case presented by Roux in 1813, the prevailing opinion until almost the end of the nineteenth century was that ligation of the vein made death inevitable, but that the only way to control severe hemorrhaging from a vein was to ligate the femoral artery. Zaufal's principle (1880) consisted in the ligation and resection of great veins of the body and limbs in order to prevent sepsis in suppurative processes. This surgical method was still being used in the first half of the twentieth century in patients with perforated appendicitis or puerperal fever. In the limb, the congestion induced in the vein had a positive effect on the healing process. The surgical treatment of leg and pelvic deep vein thrombosis was initially (1931) aimed at achieving decompression in compartment syndromes. The first thrombectomy was performed in 1937, but several operations with a successful outcome were reported at the 61st annual meeting of the German Society of Surgery in the following year.

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.

A 14-year-old African-American girl was diagnosed with antiphospholipid-positive systemic lupus erythematosus (SLE) in July 1994. The course was complicated by nephrotic syndrome, sepsis, hemolytic anemia, acute renal failure, saphenous vein thrombosis, cutaneous vasculitis, mesenteric vasculitis, appendicitis, hemorrhagic cystitis, and avascular necrosis of the hips. In August 1997, she developed ovarian and fallopian tube complications secondary to SLE. Genitourinary complications of SLE, however, are uncommon, and ovarian vasculitis has not previously been reported as a complication of SLE. This report describes the course of an adolescent patient with SLE and focuses specifically on her genitourinary complications.

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.
