We have investigated plasma beta-endorphin (beta-E), ACTH, and cortisol in two cases of congenital indifference to pain (CIP), a rare syndrome characterized by unresponsiveness to painful stimuli. As the two patients had frequent skin infections, we also studied lymphocyte response to mitogens in the absence or presence of beta-E. In addition, we explored a series of lymphocyte membrane antigens related to different aspects of the immune response, such as CD3+, CD4+, CD8+, B, NK Leu 7, Leu 9, and Leu 19, anti-interleukin-2 receptor (anti-TAC). Plasma beta-E levels in the two patients were significantly higher than in controls, whereas plasma ACTH and cortisol levels were normal. Lymphocyte response to the mitogen phytohemagglutinin was normal. The expression of Leu 7, Leu 9, and Leu 19, three antigens related to natural killer cells, was decreased by about 50%. The results indicate that in the two cases of CIP studied, high plasma beta-E levels are associated with a reduction in the expression of natural killer cells. This suggests that the two phenomena are specifically related to each other. These data represent further evidence of the possible pathophysiological relevance of the neuroendocrine-immune feedback.

In a controlled clinical study with a total of 200 patients the broad spectrum agent and antitoxin taurolidine (Taurolin) was clearly superior to conventional medication with the broad spectrum antibiotic chlortetracycline (Aureomycin) when applied topically to treat the postextraction syndrome. Thus, the mean duration of therapy (primary target criterion) with Taurolin (group A) was 5.6 days compared to 8.2 days with the standard therapy (group B). In statistical terms this difference was highly significant (p < 0.0001). Compared with the conventionally treated patient group, the clinical control parameters such as pain, swelling, secretion, tenderness to pressure and remission (secondary target criteria) in the Taurolin group exhibited not only a markedly more rapid normalisation of the score-data during the initial phase, but also an appreciably shorter interval until the patients were symptom-free. Age, gender, localisation of the lesion or facultative systemic antibiotic or analgetic administration had no demonstrable effect on the course of the treatment, although the patients in the reference group required concomitant medication with antibiotics (p = 0.007) and analgetics (p = 0.01) considerably more often than those in the Taurolin group.

The EVR is an uncommon autosomic dominant hereditary pathology that typically presents neurofibromas in the course of the spinal, cranial and neurovegetative nerves. Occasionally, neurofibromas can be found in the gastrointestinal tract. In this setting, the most frequent locations are jejunum, stomach and ileum. Seldom, they are in duodenum where could become ulcerated determining bleeding and severe pain simulating an acute pancreatitis. There are sympathetic and parasympathetic nerves in the minor epiploon arising from the splanchnic and vagus respectively. It results in a thick network around the extrahepatic biliary system that could be the neurofibromas origin; when they become bigger biliary obstruction can results needing chirurgical treatment. Previously, it is important to discard another probable causes of biliary obstruction (lithiasis, sclerosant cholangitis, biliary or pancreatic neoplasms) with all available proceedings (echosonography, CPRE, TAC, etc).

The topical anesthetic TAC (tetracaine 0.5%, adrenaline 0.05%, cocaine 11.8%) has been reported to be effective in pain control for local procedures. However, it has the potential for cocaine toxicity by absorption through an open wound. A study was undertaken to assess the systemic absorption of cocaine and its metabolites when TAC is used as a local anesthetic. Fifty-one children, 1 to 14 years of age, were enrolled in the study. Plasma for cocaine and/or its metabolite levels was available from 46 children and obtained 20 to 40 minutes after the topical anesthetic was applied. No plasma sample had detectable parent cocaine levels; however, 26 (56.5%) had cocaine metabolite levels. Ecgonine methylester levels were detected in plasma from six children and ranged from 59 to 985 ng/mL. Benzoylecgonine levels were detected in none of 19 specimens not preserved with sodium fluoride, and in 23 of 27 specimens to which sodium fluoride had been added. Benzoylecgonine levels ranged from 40 to more than 600 ng/mL. No clinical sign of cocaine toxicity was observed in any child.

A prospective evaluation of 103 consecutive children who received TAC (tetracaine, epinephrine [adrenaline], cocaine) liquid topical anesthetic for the repair of their minor dermal lacerations was performed. A unique method of TAC application was used that consisted of applying the medication to the inner margins of the wound cavity and allowing it to stand for several minutes prior to the application of a TAC-saturated gauze pad to the wound surface. Of 670 sutures placed, 637 (95%) were done without eliciting pain. The TAC topical anesthetic was more than 95% effective in providing complete anesthesia for wounds located on the face and lip; it was equally efficacious in anesthetizing larger wounds (greater than or equal to 5 cm in length and/or greater than or equal to 5 mm in depth). No adverse reactions resulted from the application of TAC. A single wound healing complication occurred in 103 patients. TAC is a safe, effective method for anesthetizing minor lacerations of the skin in children. Its painless method of application relieves patient discomfort and maximizes patient compliance during the repair procedure, both of which enhance the accurate approximation of lacerated tissue.

Clinical trials with a cross-over double-blind technique were undertaken to test chlortetracycline (Aureomycin) and the enzyme-containing dentifrice Zendium with regard to therapeutic effects on recurrent aphthous ulcers. Aureomycin was found to reduce the number of ulcers and diminish pain when compared with placebo. When groups of patients treated with Zendium and placebo dentifrice, respectively, were compared, no statistically significant difference could be demonstrated. However, when the pH value of Zendium was stepwise changed from 5.9 to 6.8, an increased fraction of patients reported complete relief from pain and ulcer(s) during the trial periods.

Topical anesthesia in the form of TAC (tetracaine, adrenaline, cocaine) solution has been used for wound repair. This pilot study was designed to determine if the topical anesthesia achieved using a mixture of lidocaine (5%) and epinephrine (1:2000) (TLE) is equivalent to the topical anesthesia obtained using a solution of tetracaine (0.5%), epinephrine (1: 2000), and cocaine (10.4%) (TAC). A prospective, randomized, double-blind trial was carried out from May 1992 to August 1992 at a community-based teaching hospital Emergency Department (ED) that receives 50,000 annual visits. Patients with facial or scalp lacerations suitable for topical anesthesia presenting to the ED were included when study physicians were in attendance. Exclusion criteria included the presence of a sensory altering substance (eg, ethanol), age younger than two years, hypertension, pregnancy, allergy to any of the study's pharmacological agents, wounds greater than six hours old, grossly contaminated wounds, and wounds longer than six centimeters. Either a TAC or TLE solution was applied to lacerations before suturing. The laceration was repaired and the patient or physician evaluated the degree of pain from the procedure by using a standardized visual pain scale. A total of 35 patients were studied. Seventeen patients were in the TLE group; 18 in the TAC group. The mean ages were compared and found to be similar (P = .40) between the two test groups. The pain scale values, the diameter of tissue blanch around laceration (halo size), and the time to laceration repair from the onset of application of anesthetic were compared and no difference was shown between the TAC and TLE groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Over the past 4 years 18 children were observed at the La Timone-Enfants Hospital in Marseille with renal lesions consequent to nonpenetrating abdominal traumas. Hematuria was reported in 14 cases (7 macroscopic and 7 microscopic) and all cases suffered from abdominal and/or lumbar pain. In relation to the diagnostic iter used: 18 echographies, 15 urographies, 13 TAC, 2 ascendant pyelographies, 2 scintigraphies with DMSA, 1 echo-Doppler and one angiography were performed. Renal lesions were classified as: 8 type 1, 5 type 2, 4 type 3, 1 type 4. Four cases were operated and one case underwent percutaneous drainage of an urohematoma. Following an analysis of these case and a revision of the literature, the authors emphasise that the evolution and progress in the diagnosis and treatment of this important aspect of traumatic pathology in children enables an almost complete recovery of kidney function in almost all cases.

The study objective was to compare the topical anesthetic LAT (4% lidocaine, 1:2,000 adrenaline, 1% tetracaine) to TAC (0.5% tetracaine, 1:2,000 adrenaline, 11.8% cocaine) for efficacy, adverse effects, and costs. The study design was a randomized, prospective, double blind clinical trial set in an inner-city emergency department with an emergency medicine residency program. Adults with linear lacerations of the face or scalp were eligible for inclusion in the study. Patients had lacerations anesthetized with topical TAC or LAT according to a random numbers table. A total of 95 patients were included in the study with 47 receiving TAC and 48 receiving LAT. Patients stated the number of sutures causing pain and patients and physicians rated the overall pain of suturing using a standard visual analog scale (VAS). The power of the study to determine a ranked sum difference of 15 was 0.8. Visual analog scale results and number and percentage of sutures causing pain were compared using Wilcoxon's Rank Sum Test. According to patients, the percentage of sutures causing pain was significantly fewer for LAT than TAC (P = .036, Interquartile Range 0.13 to 0.0 for LAT, 0.25 to 0 for TAC). Physicians found LAT statistically more effective than TAC (P = .0093, Interquartile Range 1 to 0 for LAT, 2 to 0 for TAC) but patients did not report a difference (P = .266, Interquartile Range 1 to 0 for both LAT and TAC). Our cost per application was $3.00 for LAT compared to $35.00 for TAC. Follow-up was accomplished in 91 of 95 patients (95%) with no reported complications for either medication.(ABSTRACT TRUNCATED AT 250 WORDS)

Malign small cell tumors in the thoracopulmonary region is a tumor of neuroectodermic origins with polymorphous and infrequent presentation. It is mostly found among young people, developing an aggressive and severe course. It is a small cell tumor involving small quantities of cytoplasm without glucogen, round or oval nucleus with disperse chromatin, and little prominent nucleolus without tendency of manifesting pseudo red spots, being PAS negative. Two cases which initially resembled pleuropulmonary infection are presented. Case 1: Sixteen year old male. Presented with a high fever, pleuritic thoracic pain, and a cough with little expectoration. He was diagnosed with severe pulmonary infection and parapneumonic right pleural discharge. His condition improved with antibiotic treatment, but the cough persisted. Thoracoabdominal echography showed right pleural discharge and possible hepatic mass. Surgical intervention was performed. Askin's tumor was detected by biopsy. He began treatment with chemotherapy. Case 2: Thirty-four year old woman. Presented with non-productive cough, pleuritic thoracic pain, and high fever. In the thoracic TAC, there was right pleural discharge along with images suggesting hypodense mass. Given the patient's lack of response to antibiotics, a thoracotomy was performed. The anatomopathological diagnosis was Atkin's tumor. After beginning treatment, the patient died after ten days.
