Periodontal clinical and microbiological data in desquamative gingivitis patients

Objectives

A series of patients affected by desquamative gingivitis (DG) was investigated in order to evaluate relation patterns among clinical parameters relevant to plaque-induced periodontitis, periodontal microbiological data and the presence of DG lesions.

Patients and methods

Eight oral lichen planus (OLP) and four mucous membrane pemphigoid (MMP) patients were examined. Periodontal measurements (performed at six sites per tooth on all teeth) included probing depth (PD), gingival recession (REC), clinical attachment loss (CAL) and full-mouth plaque (FMPS) and bleeding (FMBS) scores; the presence and the exact location (site by site) of DG lesions were carefully recorded. Sub-gingival plaque samples were collected and examined by means of real-time PCR for the quantitative determination of the six most important marker organisms of periodontitis. Statistically significant differences and correlation of studied variables between DG-positive and DG-negative sites were investigated in MMP and OLP cases using Mann–Whitney test (p?<?0.05) and the Spearman rank correlation coefficient, respectively.

Results

OLP gingival lesions do not significantly affect CAL, although the presence of such lesions may reduce REC and increase PD and FMPS. MMP gingival lesions significantly worsened CAL and increased REC and FMPS. In both OLP and MMP cases, no significant difference was found between DG-positive and DG-negative sites as regards the relative percentage of the investigated species on the total bacterial load. Correlations between the presence of DG lesions and clinical parameters (CAL, PD, REC) were not significant (p?<?0.05). Significant correlations were found for the presence of gingival OLP lesions and Aggregatibacter actinomycetemcomitans (AA) and for the absence of gingival MMP lesions and AA.

Conclusions

These findings are not definitive, but highlight the need for further investigations of periodontal clinical and microbiological aspects of disorders causing DG in order to clarify their potential interference with plaque-related periodontitis.     

Treatment of psoriasis with topical agents: Recommendations from a Tuscany Consensus

Psoriasis is a chronic and relapsing inflammatory skin disease, clinically characterized by erythematous and scaly plaques. Treatment approach is mainly driven by disease severity, though several factors should be considered in order to identify the optimal therapeutic choice. Mild psoriasis may be treated with a wide array of topical agents including corticosteroids, vitamin D analogs, keratolytics, and calcipotriol/betamethasone propionate compound. Because guidelines may not provide practical indications regarding the therapeutic approach, the use of topical agents in psoriasis is more individually tailored. In order to homogenize the standard of care, at least in a local setting, we collected the real‐life‐based recommendations for the use of topical therapies from an expert panel, the Tuscany Consensus Group on Psoriasis, representing all leading centers for psoriasis established in Tuscany. With this document, this consensus group sought to define principles guiding the selection of therapeutic agents with straightforward recommendations derived from a real‐life setting.     

Management of 100 consecutive cases of pancreatic serous cystadenoma: wait for symptoms and see at imaging or vice versa?

Abstract Pancreatic serous cystadenomas have a low malignancy rate. When nonsymptomatic, in selected patients, they can be managed without surgery; however, a high degree of diagnostic reliability is crucial. We admitted 100 consecutive cases (87 women with a median age of 51.86 years). Of these, 44 were symptomatic and 56 were diagnosed incidentally. Ultrasound correctly diagnosed 53% of the cases, incorrectly 31%, and was nondiagnostic in 16%. Computed tomography scan had similar rates (54%, 34% and 12%, respectively), while magnetic resonance imaging improved diagnostic accuracy to 74% and reduced incorrect diagnoses to 26%. In 21 cases, exploratory needle aspiration of the cyst was carried out; only 8 samples (38%) resulted in a diagnosis; in 12 patients (57%) insufficient material was acquired to allow for diagnosis, one case demonstrated epithelial dysplasia. In 1 patient an exploratory puncture resulted in a very serious bleeding. Sixty-eight patients were treated surgically, the 44 symptomatic cases and another 24 patients with ill-defined oligocystic lesions that could not be differentiated as serous or mucinous in the preoperative period. Two patients underwent resection because of frank tumor growth. In the two time periods analyzed (the first 7 years and the subsequent 6.5 years) the relationship between cases observed/operated on did not significantly change. Twenty-one (30.8%) distal pancreatectomies, 14 (20.5%) intermediate resections, 10 (14.7%) pancreaticoduodenectomies 4 (5.8%) enucleations, and 1 (1.4%) duodenum-preserving pancreatic head resection were carried out. Nine patients (13.2%), underwent exploratory laparotomy with a diagnostic biopsy. Another 9 underwent decompressive interventions with cystojejunostomies. The morbidity was 27.9%, with a reoperation rate of 7.3% and zero mortality. In general the patient’s pain resolved in the postoperative period. Median follow-up was 43 months (range, 4–191 months). One patient died from other causes, and all others are currently alive. In the group of 32 patients who did not undergo operation, the median follow-up is 69 months (range, 8–164 months). Until more sophisticated technologies can be developed, the current diagnostic work-up will not result in increased preoperative diagnosis of serous-cystic tumors of the pancreas. This is mainly relevant to the oligocystic forms, which account for about one fourth of all serous tumors observed. Electronic Publication     

Liver Retransplantation for Hepatic Abscess Due to Hepatic Artery Thrombosis: A Case Report

Introduction

Hepatic artery thrombosis (HAT) is a well-recognized complication of liver transplantation (LT). HAT is an important risk factor for infectious, in particular hepatic abscess, which can cause graft loss and increasing morbidity and mortality.

Nipple-sparing mastectomy for breast cancer and risk reduction: oncologic or technical problem?

BACKGROUND: We evaluated the risks and benefits of nipple-sparing mastectomy in a multiinstitutional experience in the settings of risk-reducing surgery and breast cancer treatment. STUDY DESIGN: We analyzed data on 123 patients who had undergone nipple-sparing mastectomy with breast reconstruction for prophylaxis (n=55), treatment of breast cancer (n=41), or both (n=27) at four large centers. RESULTS: Median patient age was 45 years (range 22 to 70 years). There were 192 procedures (69 bilateral, 54 unilateral). Forty-four patients had invasive cancer; 20 had ductal carcinoma in situ (DCIS); 4 had phyllodes tumor. In all of these patients, the nipple tissue was cancer free on pathologic review. Median followup was 24.6 months (range 2.0 to 570.4 months). Local recurrence developed in two patients: one had DCIS in the upper-outer quadrant, with 71.8 months of followup; the other's cancer was invasive, in the upper-outer quadrant, with 6 months of followup. Distant metastasis developed in a third patient, who died 50 months after the procedure. Breast cancer developed in two patients after prophylactic mastectomy: one in the upper-outer quadrant at 61.8 months; one in the axillary tail at 24.4 months. No patients had recurrences in the nipple-areolar complex. Necrosis of the nipple was reported in 22 of 192 patients (11%) and it was judged minimal (less than one-third total skin of nipple) in 13 of 22 patients (59%). Overall cosmesis was judged by the patient and surgeon as good to excellent in the majority of patients. Level of satisfaction with cosmetic results was similar between prophylactic and treatment patients. CONCLUSIONS: The risk of local relapse was very low in our series of nipple-sparing mastectomies performed for DCIS or invasive cancer. Nipple-sparing mastectomy in the risk-reducing and breast cancer-treatment settings may be feasible in selected patients and should be the subject of additional prospective clinical trials.     

Planar myocardial scintigraphy with 99mTc sestamibi for the evaluation of the infarct area and the efficacy of the thrombolytic therapy]

BACKGROUND: Nuclear cardiology permits the estimation of myocardial infarction size and the result of the thrombolytic therapy. The aim of the study was to demonstrate the feasibility of the planar myocardial scintigraphy with tecnetium-99m-sestamibi in the coronary intensive care unit for the early identification of the infarct size and the results of the thrombolytic therapy. MATERIAL AND METHODS: We studied 15 patients affected by a first acute myocardial infarction (AMI), 10 anterior and 5 inferior wall, treated with thrombolysis (APSAC 30U i.v.) within and interval of 3 hours from the symptoms onset, tecnetium-99m-sestamibi was injected before thrombolysis and after 3 +/- 1 hours the planar imaging was registered with a mobile gamma-camera. Scintigraphic evaluation was repeated after 24 hours and before patient discharge. Within 48 hours from the thrombolytic therapy the coronary angiography was performed for the demonstration of patency of the infarct-related artery. The left ventricle myocardial perfusion was divided in the 3 planar projections into 13 segments. The perfusion in each segment was evaluated with a perfusion score: 0 = normal, 1 = moderately reduced, 2 = severely reduced, 3 = absent. The sum of the hypoperfused segments represented the infarct size. A perfusion score improvement greater than 40% was considered a marker of reperfusion. RESULTS: The infarct size involved 4.2 +/- 1.5 segments in the anterior and 2 +/- 0.8 segments in the inferior wall infarctions (p < 0.05). The scintigraphic imaging made 24 hours after AMI allowed the diagnosis of coronary reperfusion in 10 patients. The coronarography demonstrated the infarct related artery patency in 14 patients. The nuclear imaging at patient discharge provided the diagnosis or reperfusion in 11 cases and demonstrated an improvement of the myocardial perfusion score in 8 cases. CONCLUSIONS: In patients with AMI treated with thrombolysis the scintigraphic imaging with tecnetium-99m-sestamibi is feasible with a mobile gamma-camera in the intensive coronary care unit. The quality of planar imaging is good and allows the evaluation of myocardial infarct size and the efficiency of thrombolytic therapy. An earlier scintigraphic imaging should be taken into consideration for a more timely non-invasive evaluation of patients who need coronary angiography and, if necessary, a rescue-PTCA.
