Appendicitis. A critical review of diagnosis and treatment in 1,000 cases.

One thousand cases of appendicitis seen from 1963 to 1973 were reviewed. The overall negative appendectomy rate was 20%, but in women between ages 20 and 40 it exceeded 40%. Two thirds of the negative appendectomies were due to nonsurgical lesions. Mesenteric adenitis, gastroenteritis, and abdominal pain of unknown cause accounted for one third of the errors in females and two thirds in males. These diseases were best distinguished from appendicitis on the basis of temperature and white blood cell count. The remainder of the errors in females were due to pelvic inflammatory disease or other gynecologic diagnosis and were best distinguished from appendicitis on the basis of history and physical findings. The rate of perforation was 21% overall. The incidence of wound infection was 8.5%. Use of systemic antibiotics did not affect the wound infection rate.

Mucocutaneous lymph node syndrome. A case masquerading as Rocky Mountain spotted fever.

Mucocutaneous lymph node syndrome is a recently described entity whose principal signs and symptoms include fever, unresponsiveness to antibiotics, congested conjunctivae, reddening of the oral cavity, lips, palms, and soles, exanthem, edema, nonsuppurative cervical adenitis, and desquamation of the fingertips. Almost 7,000 cases have been reported in Japan. Analysis of the 39 cases reported in the United States reveals findings similar to those in Japan. United States cases, however, have had a higher boy-to-girl ratio (2:1), and age distribution peaks at a later time (3 years of age). We report a case with many characteristics of Rocky Mountain spotted fever, including a positive Well-Felix reaction. Some cases of mucocutaneous lymph node syndrome may be misdiagnosed as Rocky Mountain spotted fever.

Intralymphatic BCG in the treatment of gynecologic malignancies: a phase I study.

Thirteen patients with a variety of advanced gynecologic malignancies were administered BCG via the dorsal lymphatics of the lower extremity in addition to standard accepted forms of therapy. Prolonged febrile courses, lymphangitis and suppurative adenitis were observed along the lymphatic pathway of the injected lower limbs. There was no correlation between reaction to a standard anergy panel and survival. There was also no correlation between reaction to a standard anergy panel and the inflammatory response to intralymphatic BCG (ILP-BCG). There was, however, a positive correlation between the inflammatory response to ILP-BCG and survival. Intralymphatic administration of immunostimulants may conceivably be of value as ancillary therapy for use in gynecologic malignancy. However, complications of this approach to immunotherapy are significant and the method should not be used until complications are decreased.

Hyperparathyroidism subsequent to neck irradiation. Risk factors.

A follow-up examination of 444 persons treated with x-rays for tuberculous cervical adenitis was performed to determine if the risk for hyperparathyroidism (HPT) following radiation exposure can be related to the age at treatment, the dose of x-rays, or the sex of the patient. The overall incidence of HPT was 14%. There was no definite age-dependent difference in susceptibility to the induction of HPT. The doses of radiation among the 63 subjects who developed HPT ranged from 0.6 to 45.7 Gy (60-4570 rad). There was a statistically significant positive correlation between the dose of radiation and the probability of developing HPT. After doses of 14 Gy (1400 rad) or more 29% of the subjects had developed HPT. After neck irradiation women had twice the relative risk of men of developing HPT. This sex ratio was lower than in the series of nonirradiated HPT patients treated at the same institution during the time of the follow-up study.

Benign and malignant thyroid nodules after neck irradiation.

A total of 444 persons were examined for the presence of thyroid nodules on average of 43 years after having been treated with x-rays for cervical tuberculous adenitis. Of this total, 101 subjects had undergone surgery for thyroid nodules: 25 for carcinoma (6%) and 76 for benign nodules (17%). Carcinoma occurred with the same frequency in multinodular and uninodular glands. Because of the uneven age distribution in the current series, it could not be decided whether there was a higher susceptibility of the young thyroid to the induction of thyroid carcinoma or benign nodules. The dosage range for the whole series was 0.40 to 50.90 Gy (40-5090 rad). There was a positive correlation between the absorbed radiation dose and the probability of developing benign and malignant thyroid nodules, even after doses of 20 Gy or more. The risk of developing thyroid carcinoma was equal for men and women, while the female-to-male ratio for benign nodules was 2.9:1, indicating that risk factors associated with females are of less importance in irradiated than in nonirradiated populations. The median latency for carcinoma was 40 years, suggesting that the increased risk of thyroid carcinoma after irradiation remains for the rest of the patient's life.

Leishmania lymphadenitis diagnosed by fine-needle aspiration biopsy.

A case of Leishmania lymphadenitis which presented clinically as an isolated left laterocervical lymph node is described. Diagnosis was made by fine-needle aspiration biopsy (FNAB), as in other cases previously reported. The material obtained yielded abundant histiocytes, multinucleated giant cells, and epithelioid microgranulomas with Leishman-Donovan pathognomic bodies in the cytoplasm of cells, together with free forms of the parasite. This paper comments on the main differential diagnoses to be considered in our region when faced with granulomatous adenitis and the role of FNAB in the identification of this parasite in endemic areas.

The history of pediatric surgery in France.

In 1741, Nicolas Andry, counsellor of King Louis XV, published a book about "orthopedics," inventing this word. The book is interesting as the author refers to beliefs and habits of the time. In 1864, Guersant published Notes About Pediatric Surgery, a real textbook which was translated into English and German and dealt with the importance of children's psychological training, anesthesia, and water or mother's milk after the operation, and also described tracheotomy, draining of cervical adenitis, and lithotrity. The classification of bone affections was still very confused. Tuberculosis and syphilis have an important place; hypospadias is not treated by surgery. In 1905, Froehlich published Pediatric Surgery Studies dealing exclusively with visceral surgery and demonstrating progress compared to Guersant's study. In 1906, Kirmisson published Pediatric Surgical Textbook, containing the first discussion of radiology and the description of the pathology of the omphalomesenteric duct and of other congenital malformations. Osteomyelitis was given its proper name, and cervical fistulas were explained. In 1914, A. Broca achieved further progress describing treatments of megacolon, intussusception, and the operation of Fredet Ramstedt. The book by Ombredanne, already out of date at the time of its publication, showed that he was not aware of the wartime, progress achieved by Ladd and Gross in the USA. French publications have diminished since then, and French pediatric surgery is still trying to find a precise identity.

A waterborne tularemia outbreak.

A waterborne tularemia outbreak is described. Forty nine cases were identified in Sansepolcro, a small Medioeval town in the province of Arezzo, Tuscany, Italy. All cases had laterocervical or sub-mandibular adenitis, and occurred within a period of three weeks during March and April 1982. The study showed association between cases and the consumption of water from an unchlorinated water system. Francisella tularensis type 1 was isolated from wild hares captured in the area.

Imaging in plague.

An 8-year-old boy presented with elevated temperature, malaise, hepatosplenomegaly, mesenteric adenitis, and septic shock. Cultures of biopsied abdominal lymph nodes as well as the blood grew Yersinia pestes. The boy's condition improved after two weeks of chloramphenicol and cefotaxime (Claforan). Two days after stopping intravenous antibiotic therapy, the patient again became febrile and complained of abdominal pain. Abdominal imaging with 111In-labeled leukocytes did not show any abnormalities, however, 67Ga-citrate scintigraphy demonstrated an abnormal focus of increased radiopharmaceutical uptake within a confluence of necrosed lymph nodes within the right upper quadrant of the abdomen. In addition, abnormal 67Ga-uptake was seen within the left hip region. Correlative imaging with computed tomography is also presented.

Non-tuberculous mycobacterial lymphadenitis in children.

Eighty-six children (44 males, 42 females) were identified as having non-tuberculous mycobacterial lymphadenitis. The diagnostic criteria were either culture of the organism from the affected lymph node (n = 68), or, when culture was negative, a positive skin test with non-tuberculous mycobacterial antigens and negative skin test responses to tuberculin purified protein derivative (PPD) in association with typical histological features (n = 18). All children had histopathological findings of granulomatous inflammation with caseation and/or acid-fast bacilli. Eighty-two percent of the children were under 5 years of age at presentation and 30% were less than 2 years old. Most (79%) were city dwellers. Lymph node enlargement had been present for less than 6 months in almost all children (97.5%) and was almost exclusively in the face and neck region (97%). Disease was confined to the involved lymph nodes in 56% but had extended beyond the confines of the infected node to form a collar stud abscess in 38% and 6% presented with a skin sinus. Extranodal extension did not show any statistically significant association with the duration of lymphadenopathy. The duration of lymphadenopathy had been greater in those children in whom an organism was not isolated on culture resected tissue (chi 2 = 10.07, P less than 0.01). All children were treated surgically, and recurrence occurred in five patients. This study describes the clinical and demographic characteristics of non-tuberculous mycobacterial lymphadenopathy in children in a population in which tuberculous adenitis is rare. Recognition of these features may allow earlier diagnosis and appropriate surgical therapy.

Humoral response to defined epitopes of tubercle bacilli in adult pulmonary and child tuberculosis.

In order to investigate the humoral response to tuberculosis in different categories of patients, serum antibody levels to six epitopes of Mycobacterium tuberculosis in adult pulmonary and child tuberculosis were determined. Serum antibody titres were determined by competitive inhibition with radio-labelled murine monoclonal antibodies in 67 adults and 85 children with tuberculosis and in 79 age-matched controls. BCG vaccination (n = 39) and self-healed tuberculosis (n = 11) in adults gave rise to higher antibody titres to TB68, TB23 and TB72 epitopes (all p less than 0.003) when compared to non-vaccinated controls (n = 18). TB68 titres were higher (p = 0.006) in self-healed than in vaccinated adults. Adult sputum-negative patients (n = 15) had higher titres to TB71 (p = 0.015) and ML34 (p = 0.02) epitopes compared to BCG-vaccinated healthy controls, while sputum-positive patients (n = 41) had higher titres to all epitopes tested (all p less than 10(-4]. The diagnostic sensitivity, with a 95% specificity, was best with the combination of probes TB23, TB68, TB72 for sputum-positive (85%) and TB78, ML34 (53%) for sputum-negative patients. Antibody titres in children with tuberculosis were lower than in adult patients; diagnostic sensitivity in histologically or microbiologically proven cases (n = 18) was only 44%, while that in mediastinal lymph-adenitis (n = 67) was 13.5%. This study suggests that the magnitude and specificity of the humoral response to tubercle bacilli varies with site and severity of infection; the implications for pathogenesis or protective immunity are discussed.

Causative role of Yersinia and other enteric pathogens in the appendicular syndrome.

In 2,861 consecutive patients undergoing appendicectomy for clinically suspected appendicitis an enteric pathogen was isolated from the appendix in almost 7% using an optimal combination of culture media. The pathogenic Yersinia enterocolitica serotypes 03 and 09 predominated (3.6%), followed by Campylobacter and nontyphoid Salmonella. The same pathogen was isolated from the stool in 72.5% of patients with a culture-positive appendix and in 84.1% of those positive for a pathogenic Yersinia. Conversely, no pathogenic Yersinia were isolated in 326 gynaecologic control patients, in whom a normal appendix was removed. No frank appendicitis but mesenteric adenitis and/or terminal ileitis were found in 62.3% of 138 patients with a culture positive appendix, and in 74.6% of those positive for a pathogenic Yersinia. Histologic findings available in 135 patients showed acute suppurative appendicitis in only six (4.5%) patients, and in only one of 73 (1.4%) positive for a pathogenic Yersinia. In contrast, 46.8% of a group of 345 culture-negative appendices showed acute inflammation. A positive stool culture in a patient with suspected appendicitis, if consistent with sonographic and clinical findings, should be taken as strong evidence against the presence of true appendicitis.

Cervical neuroblastoma in eleven infants--a tumor with favorable prognosis. Clinical and radiologic (US, CT, MRI) findings.

Cervical neuroblastoma, a disease primarily of infants, has a favorable prognosis. Eleven patients are reported. Clinical presentations (other than mass) included stridor and swallowing problems. Masses when felt were commonly mistaken for infectious adenitis. Imaging studies (US, CT, MRI) showed solid masses with vascular displacement and narrowing; intraspinal extension was absent though extension into the adjacent sites of mediastinum and skull occurred. Horner syndrome was seen in five patients with accompanying heterochromia iridis in one. Five tumors had calcification. A high index of suspicion will lead to biopsy and less delay in diagnosis once a mass is felt or imaged.

Abdominal (liver, spleen) and bone manifestations of cat scratch disease.

Cat scratch disease is usually a self-limiting illness. Patients may develop systemic complications including hepatic granulomas, splenic abscesses, mesenteric adenitis, osteolytic lesions, as well as dermatologic and CNS complications. In this paper the literature is reviewed and two cases are discussed which present the imaging findings in patients with hepatic, splenic, mesenteric, and bony manifestations of cat scratch disease.

Mycobacterium haemophilum: an emerging pathogen.

Mycobacterium haemophilum is emerging as a pathogen of immunocompromised patients particularly those with AIDS and organ transplants. Infection has also occurred in healthy children. Adults usually present with cutaneous manifestations, septic arthritis or occasionally pneumonia. Children have perihilar, cervical or submandibular adenitis. The organism grows on mycobacterial media supplemented with ferric ammonium citrate or hemin, incubated at 30 degrees C to 32 degrees C, two to three weeks after inoculation. The most active antimicrobial agents in vitro are amikacin, ciprofloxacin, clarithromycin, rifabutin and rifampin. Development of resistance to the rifamycins has been demonstrated after patients were treated for several months with several antimycobacterial agents, including the rifamycins. Treatment for several months with at least two agents demonstrated to have low MICs for the organism has been shown to be effective.

Imaging of acute appendicitis: US as the primary imaging modality.

BACKGROUND: The investigation of the acute abdomen in infants and children has evolved during the last two decades, placing imagers at the forefront of the evaluation and diagnosis of acute right lower quadrant abdominal problems. US and CT have recently been shown to be equally accurate in the diagnosis of acute appendicitis, but not everyone agrees. OBJECTIVE: To demonstrate the efficacy of triaging patients with acute abdominal problems that suggest appendicitis with US as the primary imaging modality. MATERIALS AND METHODS: We retrospectively reviewed the prospective imaging diagnoses in 622 children who presented to our emergency room (ER) and clinics with acute abdominal symptoms suggestive of appendicitis. We documented whether US or CT was performed and noted the diagnoses made. All of the patients had plain films. In addition, all patients undergoing surgical appendectomy during this time were also documented so as not to miss any cases of appendicitis. None was missed. RESULTS: There were 622 consecutive patients in our study. Three patients, diagnosed as normal, were eventually excluded because of lack of follow-up. In all, 152 patients were evaluated clinically and with plain films only. They were not subject to surgical exploration or further imaging. None returned with appendicitis. Eighty-one patients were directly subject to laparotomy after clinical and plain film evaluation. Of these patients, 20% had a normal appendix. Of the remaining 389 patients, 386 had US and three had CT alone. Four patients had both CT and US because of an inconclusive US examination. Three patients had CT alone because of their size. In total, 137 patients were diagnosed with appendicitis with US and/or CT. Four of these patients (3%) had normal appendices. Forty-two patients (less three lost to follow-up) were diagnosed as normal, and none returned with findings of appendicitis. Nine others had conditions other than acute appendicitis. Three had surgically proven, nonrelated conditions, and of the other six, one had pancreatitis and five nonsurgical adnexal problems. In all, 201 patients were diagnosed (with US) with mesenteric adenitis-enteritis, and none returned with findings of appendicitis. CONCLUSION: We attained a high degree of diagnostic accuracy in patients presenting with findings suggestive of appendicitis using US as the primary imaging modality. Our false-positive appendectomy rate was 3%. Therefore, triage of the acute abdomen with US supported by CT when required has considerable merit, especially when considering that US is noninvasive and does not use ionizing radiation.

Paediatric emergencies: non-traumatic abdominal emergencies.

Presentation with acute abdominal pain or abdominal symptopathology is a very common cause of presentation of children to hospital. The causes are dependent in part on the age of the child, in part on the presence of previous surgery, and can be divided into those that relate to congenital abnormalities at whatever age they present, acquired disease and infection. Children, particularly young children are often poor historians, and therefore the clinical examination and the laboratory investigations are important in helping to come to a diagnosis. Primary imaging of abdominal emergencies in childhood is a radiograph of the abdomen, followed by ultrasound. Further imaging depends on the results of these studies. An ordered review of the abdomen radiograph is important if the salient features on X-ray are not to be missed. Practitioners should be competent with abdominal ultrasound in children and know where to seek the causes of disease, as these are different from those that are obtained in many instances in adults. Familiarity with the likely causes is important. The three commonest causes of acute abdominal pain in childhood are, in young infants, intussusception, appendicitis and mesenteric adenitis. In older children, inflammatory bowel disease and ovarian pathology are also included. This article details the approach to imaging and the salient features of some of the conditions.
