The value of preanesthetic assessment of anemia and analysis of the hemoglobin level prior to a minor pediatric surgery has been recently questioned in some reports. This study was to retrospectively analyse 8859 pediatric patients who underwent minor surgery in the period from January 1987 to December 1990 in our hospital. They were all ASA class I-II in physical status with age ranging from one month to 19 years. Those patients with their hemoglobin values determined at other laboratories or hospitals in spite of our recognition and those suspected of having an immune or oncologic disease were excluded from this study. The mean hemoglobin value of the patients under study was 12.99 +/- 0.82 g/dl. 0.62% of the patients (55) were found to have hemoglobin values less than 10 g/dl which were similar to the results obtained by Wood et al (0.7%) in 1981 and Roy et al (0.5%) in 1990. Among the 55 anemic patients, 41 (74.5%) were at the age between 2 to 4 months (within the physiologic anemic period of infancy). Sampling of blood for routine preanesthetic hemoglobin determination which caused discomfort and pain was often rejected by pediatric patients and struggle for escape also upset the children very much. Based on the results from our analysis, we suggest that in healthy pediatric patient scheduled for minor surgery routine hemoglobin test could be excluded. Hemoglobin test is selectively performed in a patient is anemic or under suspicious circumstances. The value and shortcomings of selective hemoglobin test before surgery require further evaluation.

Treatment with rHuEpo can eliminate many symptoms that had been attributed to uremia. Repetitive punctures in children undergoing three times weekly subcutaneous (SC) rHuEpo can result in noncompliance with the therapeutic regimen. The aim of this study was to evaluate the efficacy of once weekly SC injection of rHuEpo in children with end-stage renal disease (ESRD) on CAPD. Six children (5 males, 1 female, mean-age: 6.0 years, range: 0.5 to 15.8 years) with ESRD on CAPD were treated with a regimen of rHuEpo 150 U/Kg/week SC for 12 weeks. All patients received oral iron supplementation. All children had improved appetite and well-being. The adolescents showed an increased ability to engage in regular activities. The hematocrit increased from 20.3 +/- 1.2% to 31.7 +/- 3.8% in 12 weeks. The mean weekly increase in hematocrit was 0.95 +/- 0.34%. There was no significant differences in iron indice prior to and during rHuEPO treatment. Side effects related to rHuEpo included transient pain at the site of injection in all, pruritus at the site of injection in 1 child, hyperphosphatemia in 1 infant, iron relative deficiency in 2 children and an asymptomatic increase in blood pressure in 1 hypertensive child. None of the 5 normotensive patients developed hypertension. We concluded that once weekly 150U/kg SC rHuEpo is effective in correcting anemia in children on CAPD. This regimen results in few side effects, decreases the cost of treatment and produces less distress to the patients by avoiding repetitive injections.

A systemic necrotizing vasculitis of unknown etiopathogenesis may be termed juvenile polyarteritis syndrome (JPS). The syndrome has been recognized primarily in young Beagles used for toxicologic studies. We studied 9 young Beagles with JPS. Affected dogs had fever (40 to 41.5 C), anorexia, and signs of pain in the cervical area. They had a characteristic hunched stance, and were unwilling to move. Laboratory abnormalities in all dogs included nonregenerative anemia, hypoalbuminemia, and leukocytosis characterized by a mature neutrophilia. Analysis of CSF revealed a moderate to severe neutrophilic pleocytosis and a mildly high protein concentration in most dogs. Signs of disease resolved rapidly with high doses (2.2 mg/kg of body weight, PO) of prednisone. If untreated, clinical signs and laboratory abnormalities had a remitting and relapsing course in most dogs. Findings at necropsy included necrotizing arteritis with fibrinoid necrosis, periarteritis, thrombosis, and intimal proliferation that most frequently affected small- to medium-sized vessels in the cervical spinal cord, mediastinum, and heart. An immune-mediated pathogenesis for this disease is suspected.

To determine whether non-Hodgkin's lymphoma (NHL) is related to prior medication use or health history, a population-based case-control study was conducted. A total of 619 male and female residents of Los Angeles County who were diagnosed with NHL between January 1, 1979, and June 30, 1982, were compared to individually age-, race-, and sex-matched neighborhood controls with regard to history of use of 49 different medications, 47 chronic and infectious diseases or other conditions, 15 types of immunizations, and 15 specific allergic reactions. Based on preliminary analyses, long-term regular use of aspirin and other pain relievers and greater than or equal to 2 mo of treatment with penicillin and other antibiotics were associated with significantly increased risk of NHL. Other drugs associated with greater risk of NHL were use of digitalis and estrogen replacement therapy by women, use of corticosteroids, and greater than or equal to 2 mo of use of tranquilizers. NHL was strongly associated with a prior history of cancer. Cases more frequently reported histories of kidney infections and anemia than did controls; a history of eczema appeared to be protective against NHL. Women who had been immunized against polio by injectable vaccine were at significantly lower risk of NHL than women who had not received this immunization. Among men, cholera immunization and allergy to nuts and berries were significantly protective. Subjects who had received a yellow fever immunization also had lower NHL risk. Further analyses of these data will attempt to establish the relative importance of these potential risk factors and to determine whether any are markers of early symptoms of NHL.

The clinic-epidemiologic and prognostic features of 424 cases of Ewing sarcoma observed at "Rizzoli" Institute between 1972-1990 are reported. The incidence of the tumor was higher in the second decade of life with slight predominance in the male sex. The primary lesion was especially localized in the extremity and the ratio lower/upper extremity was 5/1. We did not find, in contrast with other Authors, differences in height or in incidence of congenital malformations when compared to controls. The pain was the first common symptom at debut (90%) followed by swelling (50%) and fever (40%). Diagnosis was made 5.5 months after the first symptom and the delay was due to wrong diagnosis at debut in 3/4 of the patients. Laboratory tests showed anemia in about half of the patients and increased value of ESR (60%) and LDH (40%). Seventy-one of the patients were metastatic at presentation, none of these patients were still living after three years. At a median follow-up of 9 years 43% of the patients with localized disease, treated with adjuvant and neo-adjuvant chemotherapy remained continuously disease free, 53% developed metastatic disease and/or local recurrences and 2% had a second malignancy. In 24% of the patients metastases and/or local recurrences appeared three years after the beginning of treatment. Better prognosis was observed in female patients, without fever at diagnosis, with tumor localized at extremities and with normal value of hemoglobin, ERS and LDH. Regarding the type of treatment, better results were obtained by surgery of the primary tumor and by chemotherapy with four drugs (vincristine, cyclophosphamide, adriamycin dactinomycin) in comparison to radiotherapy of the primary tumor and chemotherapy with three drugs (vincristine, cyclophosphamide, adriamycin).

1. Head and neck tumors occur predominantly in men between 50 and 70 years of age who typically abuse tobacco or alcohol. These individuals often have poor oral hygiene and dentition as well as nutritional deficits, and achlorhydria, anemia, and iron and riboflavin deficits are common. 2. The tumor and treatment of head and neck cancer may cause many devastating effects, such as facial disfigurement, dysphagia, alterations in airway and communication, partial or total loss of taste and smell, xerostomia, pain, or fatigue. Treatment and rehabilitation may take months. 3. Although advances in technology and reconstructive surgery have not improved the overall survival rate, they preserve appearance, function, and, ultimately, the patient's quality of life.

A 41-year-old male quadriplegic patient with bilateral TMJ ankylosis was admitted for surgery under general anesthesia. Preoperative tests showed abnormal lung function and a low total serum calcium level. Premedication consisted of diazepam 10 mg orally and glycopyrrolate 0.2 mg intramuscularly 90 minutes before the start of the operation. Because of an inability to open the mouth more than 0.5 cm, a nasal fiberoptic endoscopic intubation was done under sedation and local anesthesia. For maintenance of anesthesia the patient received nitrous oxide 50% in oxygen, halothane, and alfentanil. No muscle relaxant was administered. The 2-hour operation was completed uneventfully and the patient needed no ventilatory support afterward. Major anesthetic problems of spinal injury patients can be compared to those with cervical cord transection. The stage that the condition has reached determines the dominant anesthetic problems. The chronic stage (greater than 3 months postinjury, as in this patient) is usually characterized by sympathetic overactivity. Anesthetic problems during this stage may include risk of hyperkalemia from succinylcholine, cardiovascular instability and autonomic hyperreflexia, impaired thermoregulation, anemia, chronic infections, risk of hypercalcemia, and alveolar hypoventilation. None of these problems was encountered in this patient. A surprising finding was that the low serum calcium concentration did not influence the anesthetic outcome.

The case of a 56 year old female with intermittent pain, weight loss, anaemia, and a palpable tympanic abdominal mass is reported. Barium enema showed a very redundant loop of proximal colon, which was thought to have undergone recurrent volvulus. At colonoscopy, the findings seemed normal, but a much shorter length of colon was intubated to the caecum than expected from the barium findings. The duplicated colon was discovered only intra-operatively. This unusual diagnosis should be considered when a barium enema shows a long redundant colon which is not confirmed on colonoscopy.

A number of HbSS patients presenting with aseptic necrosis of the femoral head have been seen at Mulago Hospital in Kampala, Uganda. A record review of the hospital's Sickle Cell Anaemia Clinic for the period 1985-1989 revealed that aseptic necrosis of the femoral head has been diagnosed in 2.9% (47/1611) of patients attending regularly. The largest number of diagnosed patients were in the 15-24 year old age group; peak incidence occurred in 20-24 year old women. Diagnosis in this series of patients was generally delayed and management was accordingly difficult. It is suggested that clinicians ask directly about pain in the hip of sickle cell patients rather than waiting spontaneous reporting. Such an approach may improve early detection of this potentially crippling problem.

Ultrasonography revealed evidence of liver abscess in 126 patients who were admitted to one hospital in northeastern Thailand over a 3-year period. There were 50 cases for which a pyogenic bacterial etiology was confirmed; 34 cases (group 1) were caused by Pseudomonas pseudomallei (nine patients died) and 16 cases (group 2) were caused by other bacteria (two patients died). Melioidosis was associated with anemia and underlying diabetes or renal disease; right-upper-quadrant pain and jaundice were more common in group 2 (P less than .05). Blood cultures were positive for bacteria in 68% of group 1 and 50% of group 2. Chest radiographs revealed abnormalities in 17 of 30 group 1 patients and 6 of 12 group 2 patients. The radiographic appearances of a blood-borne pneumonia suggested melioidosis. The serum indirect hemagglutination assay for antibodies to P. pseudomallei was of limited value in differentiating the two types of abscesses. Multiple hypoechoic areas on ultrasonography were significantly associated with melioidosis (P less than .01); associated splenic abscess occurred in 19 group 1 patients but only one group 2 patient (2-107, 95% confidence interval; odds ratio, 19). In an area where P. pseudomallei is endemic, these characteristic ultrasonographic findings should prompt immediate treatment for melioidosis.
