RESUMO

Follow-up after acute myocarditis is important to detect persisting myocardial dysfunction. However, recovery of atrial function has not been evaluated after acute myocarditis so far. Thirty-five patients with strictly defined acute myocarditis underwent cardiovascular magnetic resonance (CMR, 1.5 T) in the acute stage at baseline (BL) and at 3 months follow-up (FU). The study population included 13 patients with biopsy-proven "cardiomyopathy-like" myocarditis (CLM) and 22 patients with "infarct-like" (ILM) clinical presentation. CMR feature tracking (FT) was performed on conventional cine SSFP sequences. Median LA-GLS increased from 33.2 (14.5; 39.2) at BL to 37.0% (25.2; 44.1, P = 0.0018) at FU in the entire study population. Median LA-GLS also increased from 36.7 (26.5; 42.3) at BL to 41.3% (34.5; 44.8, P = 0.0262) at FU in the ILM subgroup and from 11.3 (6.4; 21.1) at BL to 21.4% (14.2; 30.7, P = 0.0186) at FU in the CLM subgroup. Median RA-GLS significantly increased from BL with 30.8 (22.5; 37.0) to FU with 33.7% (26.8; 45.4, P = 0.0027) in the entire study population. Median RA-GLS also significantly increased from 32.7 (25.8; 41.0) at BL to 35.8% (27.7; 48.0, P = 0.0495) at FU in the ILM subgroup and from 22.8 (13.1; 33.9) at BL to 31.0% (26.0; 40.8, P = 0.0266) at FU in the CLM subgroup. Our findings demonstrate recovery of LA and RA function by CMR-FT strain analyses in patients after acute myocarditis independent from clinical presentation. Monitoring of atrial strain could be an important tool for an individual assessment of healing after acute myocarditis.

RESUMO

OBJECTIVE: We aim to investigate hearing sensitivity and wideband tympanometry results in bone cement ossiculoplasty cases in present study. STUDY DESIGN: A prospective study. SETTING: Ossiculoplasty patients were grouped according to the anatomical location of bone cement application by surgery note. Ossiculoplasty and tympanoplasty patients were retrospectively invited to the clinic and evaluated. 30 bone cement ossiculoplasty cases as well as 30 Type I tympanoplasty cases (intact ossicular chain) and 30 healthy controls were included in the study and Wideband Tympanometry was performed. Tympanometric peak pressure, equivalent middle ear volume, static admittance, tympanogram width, resonance frequency, average wideband tympanometry and absorbance measurements were analyzed. RESULTS: A statistically significant improvement was observed in the hearing levels of all ossiculoplasty and type I tympanoplasty patients (p < 0.05). Bone cement ossiculoplasty groups demonstrated the remarkable differences than the type I tympanoplasty and control group in Wideband Tympanometry test parameters. In some parameters, malleus-stapes and manubriostapedioplasty groups demonstrated similarities to Type I tympanoplasty and control groups. CONCLUSION: Bone cement is an effective application for ossiculoplasty. Wideband tympanometry is a promising method for the evaluation of the middle ear dynamics.

RESUMO

We report two cases of thyroidal plasma cell granuloma. Both patients underwent surgical resection after presenting with painless neck swelling. Histopathologic examination of the specimens revealed plasmacytes infiltrating the thyroid parenchyma and immunohistochemical studies showed the polyclonal nature of the plasma cells. Plasma cell granuloma is a benign lesion and its appearance in the thyroid gland is extremely rare. Eleven prior cases with thyroid localization have been reported to date in the English literature. Nine of the plasma cell granuloma cases occurred in women, four in men (including the present cases). The clinicopathologic features and diagnostic difficulties of this rare entity are described, and its relation to inflammatory pseudotumor of other sites is discussed with a review of the literature.

RESUMO

OBJECTIVE: A significant increase in the frequency of inferior vena cava (IVC) filter placement at our large community-based academic health center led us to evaluate changes in indications, devices, and providers over the past decade. METHODS: A single-center retrospective review of all filter placements was performed comparing 76 patients in 1995 with 470 patients in 2005. Demographic data, provider data, filter type, and indications for placement were tabulated. Complications, follow-up evaluation, filter removal, and patient outcomes were examined. RESULTS: There was a greater than sixfold increase in the number of filters placed in 2005 vs 1995. There were no significant differences in patient demographics or the extent of venous thromboembolic (VTE) disease during this period except for an increase in median age. Filter placement by interventional radiologists remained approximately 50% of the total whereas placement by vascular/trauma surgeons increased to 24% and placement by cardiologists decreased to 29% (P < .001). In 2005, a smaller percentage of filters were placed for absolute indications, while filter placements for relative and prophylactic indications increased over the same time period, especially among cardiologists (P = .02). Potentially retrievable filters are increasingly being used for prophylaxis; however, only 2.4% were retrieved. An increasing number of filters were placed in patients with only infrapopliteal deep venous thrombosis (P = .07). A shift was seen to lower profile and removable filter types. Long-term patient follow-up showed little change in disease progression or in morbidity and mortality of filter insertion. CONCLUSIONS: Technological and practice pattern changes have led to an increase in filters inserted by vascular and trauma surgeons in the operating room and intensive care units. Increased diagnosis of VTE disease and newer low profile delivery systems in patients may also have contributed to the significant increase in filter placement. A shift in indications for placement from absolute toward relative indications and prophylaxis is evident over time and across providers, indicating the need for consensus development of appropriate criteria.

RESUMO

BACKGROUND: The aim of this study is to assess the prevalence of unrecognized adult celiac disease in Central Anatolia of Turkey and establish if prevalence figures are similar to other reports in the international literature. METHODS: Subjects were randomly selected from patients at the time of blood sampling because of a routine examination or suspicion of some disorder other than celiac diseases and were screened with anti-tissue transglutaminase IgA and serum IgA measurements. Duodenal biopsies were taken from the patients who were found positive for anti-tissue transglutaminase IgA and had low IgA levels. RESULTS: A total of 906 subjects between 20 and 59 years of age were included. Small bowel biopsies were performed for 55 of the 906 participants. Fifty-two of 55 participants taken biopsies had anti-tissue transglutaminase IgA levels greater than 15 IU/mL and 3 of them had low IgA levels. Celiac disease was diagnosed as 9 of 906 (0.99%). The majority of the patients with celiac disease had nonspecific gastrointestinal symptoms. There was no correlation between the titers of anti-tissue transglutaminase IgA and the severity of histopathologic findings. CONCLUSIONS: In this study, we found that unrecognized adult celiac disease in Central Anatolia affects approximately 1% of the population, and the major constellation of symptoms are nonspecific gastrointestinal related. Serologic data are not adequate for a definite diagnosis, but the anti-tissue transglutaminase IgA test has high diagnostic value and may be used as screening tool. Confirmation with intestinal biopsy is required for a definite diagnosis.

RESUMO

We report a case of nonfunctioning islet cell carcinoma of the pancreas causing a tumor thrombus in the portal vein. The patient was a 60-year-old woman whose presenting symptoms were abdominal pain, vomiting, and weight loss. We performed a subtotal pancreatectomy and splenectomy combined with partial resection of the portal vein. Histopathological studies confirmed the diagnosis of nonfunctioning islet cell carcinoma of the pancreas with a tumor thrombus in the portal vein. The patient's postoperative course was uneventful and she is doing well 25 months after the operation.

RESUMO

Adenomyoma is a rare nonneoplastic lesion of the biliary tract. We report two cases of adenomyoma; one located in the duodenum, and the other located in the ampulla Vateri. Both patients presented with jaundice, and preoperative endoscopic and radiologic procedures could not show whether the tumor was benign or malignant. Despite intraoperative frozen section in one patient, the diagnosis of adenomyoma was not confirmed until after pancreaticoduodenectomy.

RESUMO

During the period of 1996-1998 ninety-four gastrectomy specimens with gastric carcinoma referred to Erciyes University, Medical Faculty, Department of Pathology, were examined histopathologically, histochemically and immunohistochemically. General characteristics of gastric carcinomas and prognostic factors were studied. According the Lauren classification, of the 94 cases of gastric carcinomas, 56 were intestinal type, 21 were diffuse type and 17 were mixed type carcinoma. The association rates of Helicobacter pylori, chronic atrophic gastritis and intestinal metaplasia with gastric carcinomas were high. There was strong immunorectivity with HSP70 in 62,5% of the intestinal type carcinomas. This ratios were lower in diffuse and mixed type carcinomas (p<0.05). The more tumor size and invasion depth increased, the more HSP70 immunoreactivity was obtained (p<0.05). HSP70 immunorectivity was considerably higher in the patients having lymph node metastasis and vascular invasion (p<0.05). It was found that the NK cell number was low in the tumor but higher around the tumor in early gastric carcinomas, compared with advanced carcinomas (p>0.05). In the tumors larger than 10 cm with vascular invasion, NK cell number was lower around the tumor (p>0.05). Defining prognostic factors of gastric carcinomas is of importance to clinicians. It is thought that HSP70 immunoreactivity, besides invasion depth, lymph node metastasis, vascular invasion, tumor size and inflammatory reaction against the tumor, is important in prognosis and associated with advanced stage.

RESUMO

In a retrospective study, 90 American Board of Orthodontic (ABO) cases were evaluated for treatment outcome. Changes in occlusion, cephalometric skeletal and dental variables, soft tissue variables, and root resorption were evaluated. The occlusions of completed ABO cases were compared with 147 naturally occurring good-to-excellent occlusions from the Andrews Foundation for Education and Research, using the Ideal Tooth Relationship Index (ITRI). Cephalometric variables were evaluated in relation to an "acceptable range" based on established standards. Photographs were evaluated for lip posture at rest and at closure, and the incidence and the severity of root resorption of maxillary and mandibular teeth excluding second molars were evaluated from panoramic radiographs. After treatment, occlusions of ABO cases scored significantly higher overall and for all ITRI segments except the anterior interarch segment when compared with Andrew's sample. In all the ABO cases, ideal overjet and overbite were attained. Cephalometrically, the mandibular plane and the Y-axis angle showed no significant change as a result of treatment. However, skeletal dysplasia (ANB) and skeletal convexity (Na-A-Po) showed improvement. Dentally, the maxillary incisor position and inclination, the interincisal angle, and the lower incisor position ended within the acceptable range, whereas the lower incisors were proclined. Soft tissue variables also improved, lip balance and harmony, closure at rest, and closure without strain all improved. The nasolabial angle showed little change. Most of the root resorption was minor in nature and involved the maxillary and mandibular central and lateral incisors. In conclusion, the ABO cases were well treated and showed marked improvement in occlusion, cephalometric, and soft tissue changes, although experiencing minor iatrogenic effects.
