Homeopathic practice in Intensive Care Units: objective semiology, symptom selection and a series of sepsis cases

Homeopathy has been used for more than two hundred years to treat chronic disease using various approaches in a wide range of diseases. However, for acute disease and critical illness, application has been limited by inadequate training of homeopathic physicians and the small number of pertinent clinical studies. In view of the difficulty of practising homeopathy in Intensive Care Units (ICU), a protocol was developed to facilitate description of objective homeopathic symptoms with a ranking of symptoms appropriate for these situations (Protocol for Objective Homeopathic Semiology). Examples of favorable results with individualized homeopathic treatments for a series of cases of Systemic Inflammatory Response Syndrome (sepsis) are described. Homeopathy (2008) 97, 206-213.

Studies of RET gene expression and acetylcholinesterase activity in a series of sporadic Hirschsprung`s disease

The purpose is to present the studies of RET gene expression and acetylcholinesterase activity in 23 patients operated for Hirschsprung`s disease (HD). The patients underwent either transanal endorectal pull-through or Duhamell`s procedure. Full-thickness intestinal samples from the three different segments (ganglionic, intermediate and aganglionic) were collected. Each tissue sample was divided in two portions, one for AChE histochemical staining and the other for examination of RET mRNA expression level. All patients had an uneventful postoperative recovery. In all patients, the AChE stainings demonstrated the absence of activity in the ganglionic area, the marked increase of positive fibers in the aganglionic area, and little increase of positive fibers in the intermediate area. In the ganglionic and intermediate areas, all patients (100%) showed significant RET gene expression. In the aganglionic area, 18 patients (78.3%) did not present gene expression and the other five patients (21.7%) presented gene expression that was similar to the ganglionic and intermediate areas. The results reinforce the conclusion that the method of AChE staining is effective for the diagnosis of intestinal aganglionosis and confirm the knowledge that genes beyond RET may be implicated in the genesis of sporadic cases of HD.

Genital Manifestation of Graft-vs.-Host Disease: A Series of Case Reports

Introduction. After hematopoietic stem cell transplantation (HSCT), many patients present genital graft-vs.-host disease (GVHD) that can culminate with sexual problems, which are poorly dimensioned. Aim. We hope to draw attention to the need to perform genital biopsy to diagnose genital GVHD, and thus to call attention to the need to incorporate careful attention to sexual health in the treatment of these patients. Methods. Five allogeneic stem cell transplant recipients complaining of coital pain after HSCT were clinically diagnosed for genital GVHD. Genital biopsies were given for histological analysis, and microphotographs of the corresponding marked field in the slide were taken. Specimens were evaluated by the site pathologist and then sent to a reference pathologist, each blinded to the histological findings. A literature search was performed in PubMed/MEDLINE (1966-2009) for cross-sectional and cohort studies or trials related to genital GVHD. Expert opinions peer reviews and case reports were also considered. Main Outcome Measures. HSCT, genital GVHD, genital biopsy. Results. The biopsy showed evidence of dilated apoptotic cells in the basal layer and detachment of the epithelial lining of the mucosa, hyalinization and thickening of collagen fibers, capillary ectasia, and mononuclear inflammatory infiltrate of the submucosa. Three patients presented vulval lesion such as leucoplasia and ulcer on the large lip. Histological analyses showed evidence of epithelial hyperplasia and influx of inflammatory cells to the epithelial surface, intercellular edema and spongiosis, apoptotic bodies on the basal layer of the epithelium, spongiosis, and nuclear vacuolization. A common treatment based on corticotherapy resulted in complete remission of coetaneous or mucous genital lesions in all five patients. Conclusion. Genital biopsy is important to differentially diagnose GVHD and secondary symptoms due to hypoestrogenism. Prevention is the most important step in controlling the evolution GVHD in the vagina to prevent vaginal obstruction and sexual dysfunction. da Silva Lara LA, de Andrade JM, Mauad LMQ, Ferrarese SR, Marana HRC, Tiezzi DG, and de Sa Rosa e Silva ACJ.

Paracoccidioidomycosis Epidemiological Features of a 1,000-Cases Series from a Hyperendemic Area on the Southeast of Brazil

Paracoccidioidomycosis has been known for over 100 years, and until now, there were only few estimates of the disease`s incidence. We aim to analyze 1,000 cases treated between 1960 and 1999 at Ribeirao Preto city, Sao Paulo, Brazil, where the disease`s incidence range detected was 1.6 to 3.7 cases per 100,000 habitants per year (mean = 2.7 cases/year). We observed a male to female ratio of 6:1 and an age distribution from 3 to 85 years. The acute/subacute form of the disease accounted for 25.4% of cases. Most of the patients (93.5%) had lived or worked in rural areas before the disease development. Smoking and alcoholism were reported by 64.7% and 37.2% of patients, respectively. Comorbidities identified included tuberculosis (8.3%), Chagas` disease (8.6%), and human immunodeficiency virus/acquired immunodeficiency syndrome (4.2%). The present study revealed an area in Brazil where paracoccidioidomycosis is hyperendemic (has the highest reported incidence of this disease); this endemic area is probably caused by geological and climatic conditions as well as intensive agriculture.

Pompe disease in a Brazilian series: clinical and molecular analyses with identification of nine new mutations

Pompe disease (glycogen storage disease type II or acid maltase deficiency) is an inherited autosomal recessive deficiency of acid alpha-glucosidase (GAA), with predominant manifestations of skeletal muscle weakness. A broad range of studies have been published focusing on Pompe patients from different countries, but none from Brazil. We investigated 41 patients with either infantile-onset (21 cases) or late-onset (20 cases) disease by muscle pathology, enzyme activity and GAA gene mutation screening. Molecular analyses identified 71 mutant alleles from the probands, nine of which are novel (five missense mutations c.136T > G, c.650C > T, c.1456G > C, c.1834C > T, and c.1905C > A, a splice-site mutation c.1195-2A > G, two deletions c.18_25del and c.2185delC, and one nonsense mutation c.643G > T). Interestingly, the c.1905C > A variant was detected in four unrelated patients and may represent a common Brazilian Pompe mutation. The c.2560C > T severe mutation was frequent in our population suggesting a high prevalence in Brazil. Also, eight out of the 21 infantile-onset patients have two truncating mutations predicted to abrogate protein expression. Of the ten late-onset patients who do not carry the common late-onset intronic mutation c.-32-13T > G, five (from three separate families) carry the recently described intronic mutation, c.-32-3C > A, and one sibpair carries the novel missense mutation c.1781G > C in combination with known severe mutation c.1941C > G. The association of these variants (c.1781G > C and c.-32-3C > A) with late-onset disease suggests that they allow for some residual activity in these patients. Our findings help to characterize Pompe disease in Brazil and support the need for additional studies to define the wide clinical and pathological spectrum observed in this disease.

Treatment of Brain Arteriovenous Malformations by Double Arterial Catheterization with Simultaneous Injection of Onyx: Retrospective Series of 17 Patients

BACKGROUND AND PURPOSE: The use of Onyx in the treatment of intracranial AVMs has increased the cure rate of endovascular embolization compared with the use of liquid adhesive agents. Inadvertent occlusion of the draining veins before the complete exclusion of the nidus constitutes a major risk of bleeding. We report a case series using the technique of double simultaneous arterial catheterization as an approach to achieve the complete, exclusion of the nidus before reaching the venous drainage, through a more controlled hemodynamic filling. MATERIALS AND METHODS: Between April 2008 and November 2009, 17 patients with brain AVMs were treated by the DACT. The mean age of the patients was 32.7 years (range, 6-54 years), with 9 females and 8 males. The clinical onset was characterized by intracranial hemorrhage in 8 patients and by seizures in 7. The size of the AVMs ranged from 13 to 54 mm (average, 26.2 mm). The DACT was always used with the objective of curing the AVM. RESULTS: All 17 patients completed the EVT. The average number of sessions conducted was 1.4 (range, 1-3 sessions), with the average injection amount of 6.9 mL of Onyx (range, 2-25.2 mL). Sixteen AVMs (94.1%) were angiographically cured by embolization. Clinical complications occurred in 2 patients (11.7%); 1 of these was permanent (5.9%). No deaths were registered. CONCLUSIONS: This preliminary series shows that the DACT presents satisfactory results when used with curative intent.

Efficacy of Profile .04 taper series 29 in removing filling materials during root canal retreatment-an in vitro study

Objective. The aim of this study was to compare Profile .04 taper series 29 instruments and hand files for gutta-percha removal. Study design. Twenty maxillary central incisors with a single straight canal were instrumented and filled. The teeth were divided into 2 groups of 10 specimens each, according to gutta-percha removal techniques: Group 1- Profile series 29 and Group 2- hand files and solvent. The amount of time for gutta-percha removal and the number of fractured instruments were evaluated. Radiographs were taken and the teeth were grooved longitudinally and split. The area of residual debris was measured using computer software. Results. The time for filling material removal was significantly shorter when Profile series 29 was used (P = .00). Regarding cleanliness, there were no statistical differences in the teeth halves evaluations (P = .05). Hand instruments cleaned the canals significantly better than Profiles, in the radiographic analysis considering the whole canal. Overall, the radiographic analysis showed a smaller percentage of residual debris than the teeth halves analysis. Conclusion. The Profile series 29 instruments proved to be faster than hand instruments in removing root filling materials; however, hand instruments yielded better root canal cleanliness. Some residual debris was not visualized by radiographs. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2009; 108: e46-e50)
