Cicatricial Pemphigoid in a 6-Year-Old Child: Report of a Case and Review of the Literature

Cicatricial pemphigoid has been documented previously in only four patients under the age of 20 years. We report a 6-year-old male who had erosions of the oral and genital mucosa, conjunctivitis, hoarseness, dysphagia, recurrent vomiting, and weight loss. Upper airway obstruction due to a chronically inflamed and scarred epiglottis necessitated tracheostomy. Biopsy of tissue from a solitary cutaneous lesion demonstrated a subepidermal bulla. Direct and indirect immunofluorescence confirmed a diagnosis of cicatricial pemphigoid. Therapy was begun consisting of prednisone, 2 mg per kg per day, in combination with dapsone, 2 mg per kg per day. He did not improve until the prednisone dosage was increased to 4 mg per kg per day.     

Chronic Abdominal Pain In Children: a Technical Report of the American Academy of Pediatrics and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition

Chronic abdominal pain, defined as long-lasting intermittent or constant abdominal pain, is a common pediatric problem encountered by primary care physicians, medical subspecialists and surgical specialists. Chronic abdominal pain in children is usually functional-that is, without objective evidence of an underlying organic disorder. The Subcommittee on Chronic Abdominal Pain of the American Academy of Pediatrics and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition has prepared this report based on a comprehensive, systematic review and rating of the medical literature. This report accompanies a clinical report based on the literature review and expert opinion.The subcommittee examined the diagnostic and therapeutic value of a medical and psychologic history, diagnostic tests, and pharmacological and behavioral therapy. The presence of alarm symptoms or signs (such as weight loss, gastrointestinal bleeding, persistent fever, chronic severe diarrhea and significant vomiting) is associated with a higher prevalence of organic disease. There was insufficient evidence to state that the nature of the abdominal pain or the presence of associated symptoms (such as anorexia, nausea, headache and joint pain) can discriminate between functional and organic disorders. Although children with chronic abdominal pain and their parents are more often anxious or depressed, the presence of anxiety, depression, behavior problems or recent negative life events does not distinguish between functional and organic abdominal pain. Most children who are brought to the primary care physician's office for chronic abdominal pain are unlikely to require diagnostic testing. Pediatric studies of therapeutic interventions were examined and found to be limited or inconclusive.     

Glial bFGF and S100 immunoreactivities increase in ascending dopamine pathways following striatal 6-OHDA-induced partial lesion of the nigrostriatal system: a sterological analysis

S100, a calcium-binding protein, and basic fibroblast growth factor (bFGF, FGF-2) are found predominantly in astrocytes in the central nervous system. Those molecules show trophic properties to neurons and are upregulated after brain lesions. The present study investigated the changes in the S100beta and bFGF immunoreactivities after a partial lesion of the rat midbrain ascending dopamine pathways induced by intrastriatal injection of 6-hydroxydopamine (6-OHDA). Stereological method revealed increases in the estimated total number and density of bFGF immunoreactive astroglial profiles in the ipsilateral pars compacta of the substantia nigra (SNc) and ventral tegmental area (VTA). Increases in the counts of astroglial S100beta immunoreactive profiles were found in the striatum, SNc, and VTA mainly ipsilateral but also in the contralateral nuclei. These results open up the possibility that interactions between astroglial S100beta and bFGF may be relevant to paracrine events related to repair and maintenance of remaining dopamine neurons following striatal 6-OHDA induced partial lesion of ascending midbrain dopamine pathway.     

So what is the role of menstrual bacterial endotoxin?

Bacterial infections may adversely affect ART. However, the meaning and risks of menstrual endotoxin are not known.     

Bilateral anterior thalamic nucleus lesions and high-frequency stimulation are protective against pilocarpine-induced seizures and status epilepticus

OBJECTIVE: The thalamus is thought to play an important role in secondary generalization of seizures. The aim of the present study was to investigate the influence of anterior thalamic nucleus lesions and high-frequency stimulation in the pilocarpine model of secondarily generalized seizures in rats. METHODS: Adult Wistar rats underwent unilateral (n = 7) or bilateral anterior nucleus thalamotomies (n = 10), or unilateral (n = 4) or bilateral (n = 9) anterior thalamic nucleus stimulation through implanted electrodes. Control animals (n = 9) received bilateral implants but no stimulation. Seven days after these procedures, animals were provided pilocarpine (320 mg/kg intraperitoneally) to induce seizures and status epilepticus (SE). Electrographic recordings from hippocampal and cortical electrodes were evaluated, and ictal behavior was assessed. RESULTS: In the control group, 67% of the animals developed SE 15.3 +/- 8.8 minutes after pilocarpine administration. Neither unilateral anterior nucleus lesions nor stimulation significantly reduced the propensity or latency for developing seizures and SE. Bilateral thalamic stimulation did not prevent SE (observed in 56% of the animals), but it significantly prolonged the latency to its development (48.4 +/- 17.7 min, P = 0.02). Strikingly, no animal with bilateral anterior nucleus thalamotomies developed seizures or SE with pilocarpine. CONCLUSION: Bilateral anterior thalamic nuclear complex stimulation and thalamotomies were protective against SE induced by pilocarpine.     

Use of an oxygen therapeutic as an adjunct to intraoperative autologous donation to reduce transfusion requirements in patients undergoing coronary artery bypass graft surgery

BACKGROUND: The benefits of intraoperative autologous donation (IAD) in reducing the need for allogeneic blood transfusion in surgery have been debated for several years. The purpose of this study was to determine if IAD alone or in conjunction with hemoglobin raffimer (HR) confers a reduction in red cell or blood component transfusion compared with results in standard clinical practice. STUDY DESIGN: The Phase III clinical trial was a multicenter, randomized, double-blind study to determine the efficacy and safety of HR versus 10% pentastarch when used to facilitate IAD in 299 patients undergoing primary coronary artery bypass grafting. The patients received HR or pentastarch as an adjunct to IAD immediately before cardiopulmonary bypass. Results were compared with transfusion requirements for 150 matched patients in the reference group. RESULTS: The frequency of allogeneic RBC transfusion in the HR, pentastarch, and reference groups was 56%, 76%, and 95%, respectively. The number of allogeneic red cell units used was 49 in the HR group, 104 in the pentastarch group, and 480 in the reference group (p < 0.001). The total number of non-RBC units administered was 150 in the HR group, 238 in the pentastarch group, and 270 in the reference group. CONCLUSIONS: In this study, patients treated with HR in conjunction with IAD received fewer transfusions overall and a lower volume of allogeneic RBCs and non-RBC allogeneic blood products than did the two comparison groups. This confers a real benefit on the overall blood supply by decreasing use and increasing availability.     

Cancer mortality among Japanese immigrants and their descendants in the state of São Paulo, Brazil, 1999-2001

BACKGROUND: Only a few studies on the mortality of Japanese immigrants have been conducted in Brazil despite a large population of Japanese immigrants and their different environment and lifestyle from Japanese living in Japan. METHODS: To compare cancer mortality between Japanese in Japan and Japanese immigrants or Brazilians in the state of S?o Paulo, Brazil, we obtained official death certificates registered during 1999-2001. The standardized mortality ratio (SMR) or the standardized proportional mortality ratio (SPMR) of major cancer sites was calculated for the first generation of Japanese immigrants to Brazil (Japan-born), their Brazil-born Japanese descendants, and native Brazilians using mortality data of Japanese in Japan as a standard. RESULTS: The SMRs of stomach and colorectal cancer did not differ between the Japan-born residents of Brazil and the native Japanese, but significantly low SMRs were found among the native Brazilians. Compared with the native Japanese, we observed significantly lower SMRs for liver, gallbladder and lung cancer and significantly higher SMRs for prostate, cervical, and brain and nervous system cancer among both the Japan-born residents of Brazil and the Brazilians. Generally, the SPMR results were similar to those of the SMRs. Significantly high SPMRs for breast and uterine cancer were found for both the Japan- and Brazil-born residents of Brazil, although the Japan-born residents had increased SMRs, but not significantly so. CONCLUSIONS: We confirmed the different cancer mortality pattern in the Japanese immigrants from that in Japanese in Japan, thus demonstrating the relative importance of the environment in the development of cancer.     

Distribution and morphometry of skeletal muscle fibers in patients with chronic obstructive pulmonary disease and chronic hypoxemia

This study was designed to assess the size and distribution of muscle fiber types in patients with severe chronic obstructive pulmonary disease and stable chronic hypoxemia. Brachial biceps biopsies were performed in 8 patients and 12 controls. Histochemistry was used to count and determine the cross-sectional area of the various fiber-types (1, 2a, and 2b). A significant reduction (P < 0.05) in the proportion of type 2a fibers and an increase in the proportion and cross-sectional area of type 2b fibers were seen in hypoxemic patients. These findings suggest an adaptation of the muscle fibers to a low partial pressure of oxygen in arterial blood.     

Symptoms of depression and anxiety (MHI) following acute medical/surgical hospitalization and post-discharge psychiatric diagnoses (DSM) in 839 geriatric US veterans

OBJECTIVE: We addressed the relatively unexplored use of screening scores measuring symptoms of depression and/or anxiety to aid in identifying patients at increased risk for post-discharge DSM-IV Axis I diagnoses. We were unable to find such studies in the literature. METHOD: Elderly veterans without recent psychiatric diagnoses were screened for depression and anxiety symptoms upon admission to acute medical/surgical units using the Mental Health Inventory (MHI). Following discharge, those who had exceeded cut-off scores and had been randomized to UPBEAT Care (Unified Psychogeriatric Biopsychosocial Evaluation and Treatment, a clinical demonstration project) were evaluated for DSM diagnoses. We report on 839 patients, mostly male (96.3%; mean age 69.6 +/- 6.7 years), comparing three groups, i.e. those meeting screening criteria for symptoms of (i) depression only; (ii) anxiety only; and (iii) both depression and anxiety. RESULTS: Despite absence of recent psychiatric history, 58.6% of the 839 patients received a DSM diagnosis post-discharge (21.8% adjustment; 15.4% anxiety; 7.5% mood; and 14.0% other disorders). Patients meeting screening criteria for both depression and anxiety symptoms received a DSM diagnosis more frequently than those meeting criteria for anxiety symptoms only (61.9% vs 49.0%, p = 0.017), but did not differ significantly from those meeting criteria for depressive symptoms only (61.9% vs 56.8%, p = 0.174). Although exceeding the MHI screening cut-off scores for depression, anxiety, or both helped to identify patients with a post-discharge DSM diagnosis, the actual MHI screening scores failed to do so. CONCLUSION: Screening hospitalized medical/surgical patients for symptoms of depression, anxiety, and particularly for the combination thereof, may help identify those with increased risk of subsequent DSM diagnoses, including adjustment disorder.
