Abstract
Graft versus host disease (GVHD) occurs after bone marrow transplantation and is one of the most important causes of death worldwide. Reviews demonstrated GVHD patients with involvement of various tissues and organs, such as salivary glands. The diagnosis of acute GVHD has been the biopsies and the histopathologic evaluation of tissue from an involved organ. These procedures are invasive. Saliva proteins as possible biomarker for GVHD could facilitate the management and diagnosis accuracy. For support the proposed hypotheses, in this pilot study we collected whole saliva samples from patients with undergoing allogeneic hematopoietic cell transplantation (HCT) and from healthy subjects. Samples were collected prospectively between pre-transplant, thirty days, one hundred and, two hundred days after transplant. The proteomic profile was analyzed using SDS-PAGE and LCMS-ESI-IT-TOF mass spectrometry. The relevant personal data, past medical history were also recorded. The most relevant proteins found exclusively in GVHD patients were: CSF2RB, Protocadherin (Pcdh) Fat 2 precursor, protein capicua homolog isoform CIC-S, MUC16 and RGPD8_HUMAN RANBP2. This study aims to conduct an initial evaluation of the possible presence of such biomarkers in saliva from GVHD patients, and suggested a potential application of proteomics analysis as a alternative method to diagnose GVHD.

Abstract
The aim of this longitudinal prospective study was to evaluate the effects of periodontal treatment on the clinical, microbiological and immunological periodontal parameters, and on the systemic activity (ESSDAI) and subjective (ESSPRI) indexes in patients with primary Sjögren's Syndrome (pSS). Twenty-eight female patients were divided into four groups: pSS patients with or without chronic periodontitis (SCP, SC, respectively), and systemically healthy patients with or without chronic periodontitis (CP, C, respectively). Periodontal clinical examination and immunological and microbiological sample collection were performed at baseline, 30 and 90 days after nonsurgical periodontal treatment (NSPT). Levels of interleukin IL-1β, IL-8 and IL-10 in saliva and gingival crevicular fluid (GCF) were evaluated by ELISA, as well as the expression of Porphyromonas gingivalis (Pg), Aggregatibacter actinomycetemcomitans, (Aa) Tannerella forsythia (Tf), and Treponema denticola (Td), by qPCR. Systemic activity and pSS symptoms were evaluated by ESSDAI and ESSPRI. NSPT resulted in improved periodontal clinical parameters in both SCP and CP groups (p>0.05). Pg, Aa, and Tf levels decreased after NSPT only in CP patients (p<0.05). Significantly greater levels of IL-10 in GCF were verified in both SCP and CP groups (p<0.05). SCP patients showed increased salivary flow rates and decreased ESSPRI scores after NSPT. In conclusion, NSPT in pSS patients resulted in improved clinical and immunological parameters, with no significant effects on microbiological status. pSS patients also showed increased salivary flow and lower ESSPRI scores after therapy. Therefore, it can be suggested that NSPT may improve the quality of life of pSS patients.

Abstract
This study aimed to evaluate the efficacy of piroxicam associated with low-level laser therapy compared with single therapies in 32 patients presenting temporomandibular joint arthralgia in a random and double-blind research design. The sample, divided into laser + piroxicam, laser + placebo piroxicam and placebo laser + piroxicam groups, was submitted to the treatment with infrared laser (830 nm, 100 mW, 28 s, 100 J cm(-2) ) at 10 temporomandibular joint and muscle points on each side during four sessions concomitant to take one capsule a day of piroxicam 20 mg during 10 days. The treatment was evaluated throughout four sessions and 30 days follow-up through visual analogue scale (VAS), maximum mouth opening and joint and muscle (temporal and masseter) pain on palpation. The results showed that all the study groups had a significant improvement in the VAS scores (P < 0·05), and there were no significant group differences. Piroxicam was effective in the reduction of joint and muscle pain on palpation (P < 0·05) and showed the lowest temporal pain (P = 0·02) at the 30-day follow-up. The combination of low-level laser therapy and piroxicam was not more effective than single therapies in the treatment of temporomandibular joint arthralgia. The use of piroxicam was more effective in the following 30 days.

Abstract
This work is a retrospective study of latrodectism in the State of Bahia, Brazil, from August 1980 to July 1990. The data concerning the accidents were obtained from file cards at the Antivenom Information Center of Bahia (AVICB). Latrodectus curacavienis was the ethiologic agent identified in 28% of the arachnid accidents. The major incidence was registered in urban area (57%) affecting men (70%) more than women, with 10 to 29 year-old age group (58%). Local pain (56%), erythematous papula (29%) and light oedema (17%) were the principal local symptoms. Pain in the limbs (29%), tremor and rigidities (29%), sweating (28%), limbs and arms paresthesia (21%) and abdominal pain (17%) were systemic ones. The treatment was mainly symptomatic (67%) and antivenin serum was used in 21% of the cases. After serotherapy, 64% of the patients left the hospital within less than 24 hours.
