Hypothenar island flap: A safe and excellent choice for little finger defects

Soft-tissue defects of the little finger are challenging especially when bone, tendon or vascular pedicle is exposed because of trauma. The hypothenar island flap is easy to harvest and has a good colour and texture match to the little finger pulp. We present nine clinical cases of soft tissue defects of the little finger covered using the reversed hypothenar fasciocutaneous island flap. This article intends to highlight the ease of elevation and good clinical results of the hypothenar flap which is rarely used.KEY WORDS: Hypothenar island flap, island flap, soft-tissue defects of the little finger     

Pheochromocytoma Management,Outcomes and the Role of Cortical Preservation

Objectives

To evaluate the management and outcome of children with pheochromocytoma and determine the role of cortex preservation in cases of bilateral disease.

Methods

Retrospective review of children, below 12 y of age, with pheochromocytoma managed between November 2003 and December 2012 was done.

Results

Twelve patients, nine boys and three girls with median age 9 y were enroled. Eleven (92 %) had adrenal tumors and in one it was extra-adrenal. Five (42 %) had bilateral disease. Ten presented with hypertension, one with headache and one with abdominal pain and fever. All were stabilized pre-operatively with alpha and beta blockers and volume expansion. Six children with unilateral disease underwent total adrenalectomy. Out of five with bilateral disease, one child underwent bilateral total adrenalectomy and was later started on hormone replacement. Remaining four underwent total adrenalectomy on one side and partial on the other side. Post-operatively all became symptom free and normotensive and were off medications within 1 mo. Two children developed recurrence 1 mo post-operatively, one with an initial unilateral pheochromocytoma and one with paraganglionoma. At the last follow up, 10 out of 12(83 %) were disease free while two with recurrence are still awaiting surgery.

Conclusions

Surgical resection of pheochromocytoma is effective treatment to achieve cure and prolong survival. Cortex preservation should be done in bilateral disease as risk of recurrence in such cases seems to be of lesser significance as compared to the morbidity and mortality of adrenal insufficiency and consequent lifelong hormone replacement.     

A method for fabricating an implant-retained orbital prosthesis using the existing prosthesis

This article describes a time-saving technique for fabricating a new implant-retained orbital prosthesis using the patient's existing prosthesis. The location of the ocular component is transferred; the position and openings of the palpebral anatomic structures and the precise anatomic details of the existing orbital prosthesis are duplicated. Making the impression, fabricating the definitive cast, alignment of the ocular component, and completing the wax sculpture of the prosthesis are accomplished in one appointment.     

Two-year study of alternative conservative treatment modalities for early anterior permanent tooth loss

Premature tooth loss in children may consist of single or multiple, primary or permanent, and anterior or posterior units of the dentition. This tooth loss may be due to either trauma or caries and, in some cases, to congenital or genetic defects. With anterior tooth loss cases, there are several problems the dental practitioner must consider. These are space maintenance, masticatory function, speech and esthetic appearance.     

Does periodontal disease reflect atherosclerosis in continuous ambulatory peritoneal dialysis patients?

BACKGROUND: Chronic infection and inflammation, including periodontitis, are linked to an increased risk for atherosclerosis. To investigate the possible adverse effects of periodontitis in continuous ambulatory peritoneal dialysis (CAPD) patients, we compared periodontal severity with inflammation and malnutrition, which are associated with poor atherosclerotic outcome in CAPD patients. METHODS: A total of 110 CAPD patients were included in this study to evaluate their clinical periodontal status by using the plaque index, gingival index, and periodontal disease index. Values for nutritional and inflammatory markers and atherosclerotic risk factors were included for analysis with the periodontal index. Analysis of variance, post hoc Tukey's honestly significant difference, univariate and multivariate linear regression analysis, Pearson correlation analysis, and chi2 analysis were used in the evaluation of the data. RESULTS: Poor oral health status was exhibited by 85.5% of our CAPD patients with periodontal disease. We found that age and longer dialysis duration were associated with the severity of periodontitis. Parameters of malnutrition and inflammation and atherosclerotic risk factors also were associated with poor periodontal status. We carried out multiple regression analysis and found that age, albumin level, and duration of dialysis were associated independently with the severity of periodontitis in CAPD patients. A higher percentage of patients in the severe periodontitis group had malnutrition (chi2 = 59.4; P < 0.001), inflammation (chi2 = 60; P < 0.001), and atherosclerosis (chi2 = 65.6; P < 0.001). CONCLUSIONS: Periodontal health is poor in CAPD patients and correlates with markers of malnutrition, inflammation, and atherosclerosis. The diagnosis and treatment of periodontal diseases require better awareness.     

Comparative study to evaluate the efficacy of surgical and conservative techniques for apexification in young permanent teeth with open apices

The Study was conducted to compare and evaluate the effectiveness of surgical and conservative approach for apexification. Twenty-four non-vital permanent maxillary anterior teeth were selected for this study. The teeth selected were having wide apical foramen and definite radiolucent periapical area. Twelve teeth were treated under conservative method and another 12 teeth with surgical method using 'Renew' (A radioopaque calcium Hydroxide paste). The patient were recalled after 1 1/2, 3, 4 and 6 Months. The results of the study indicated that Calcific bridge formation is rapid in teeth treated with conservative technique. However, periapical repair is accelerated in teeth treated by surgical technique, though the results are comparable at the end of 6 months, So the conservative approach is preferred as it saves surgical trauma. In conservative technique, 75% of the teeth showed calcific bridge formation and 100% showed decrease in periapical radiolucent area by 3.56 mm (mean) after 6 months. In surgical technique the radiographic evidence of calcific bridge formation was noticed in 54.51% of teeth after 6 months. However in 100% of teeth there was decrease in periapical radiolucent area by 3.53 mm (mean) after 6 months.     

Salivary infectious agents and periodontal disease status

Saygun I, Nizam N, Keskiner I, Bal V, Kubar A, Aç?kel C, Serdar M, Slots J. Salivary infectious agents and periodontal disease status. J Periodont Res 2011; 46: 235–239. © 2011 John Wiley & Sons A/S Background and Objectives: The potential of salivary microorganisms to diagnose periodontal disease and to guide periodontal treatment is a research topic of current interest. This study aimed to determine whether the salivary counts of periodontopathic microbes correlated with the periodontal pocket counts of the same infectious agents, and whether the salivary counts of the test infectious agents could distinguish among individuals with periodontal health and various types of periodontal disease. Material and Methods: The study included 150 systemically healthy adults, of whom 37 were periodontally healthy, 31 had gingivitis, 46 had chronic periodontitis and 36 had aggressive periodontitis. Each study subject contributed microbial samples from the two deepest periodontal pockets of the dentition and from whole saliva. Aggregatibacter actinomycetemcomitans, Campylobacter rectus, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythia and Epstein–Barr virus were identified using the TaqMan real‐time PCR methodology. Statistical analysis was performed using the Mann–Whitney U‐test and the receiver operating characteristic statistics. Results: C. rectus, F. nucleatum, P. gingivalis, P. intermedia and T. forsythia occurred with significantly higher copy‐counts in salivary samples from patients with gingivitis, chronic periodontitis and aggressive periodontitis than from periodontally healthy individuals. A. actinomycetemcomitans only showed higher salivary copy‐counts in subjects with aggressive periodontitis compared with subjects with healthy periodontium, and the salivary copy‐counts of Epstein–Barr virus did not reveal any significant difference among the four subject groups studied. The diagnostic sensitivity for periodontitis was 89.19 for P. gingivalis and for T. forsythia and 86.49 for P. intermedia, with specificities ranging from 83.78 to 94.59. The optimal copy‐counts per mL saliva for identifying periodontitis were 40,000 for P. gingivalis, 700,000 for T. forsythia and 910,000 for P. intermedia. Conclusion: Salivary copy‐counts of P. gingivalis, T. forsythia and P. intermedia appear to have the potential to identify the presence of periodontitis, whereas the salivary level of the other test infectious agents may possess little or no diagnostic utility. Longitudinal studies are warranted to determine the ability of salivary copy‐counts of major periodontopathic bacteria to predict future periodontal breakdown.     

Gingival crevicular fluid alkaline phosphatase levels in postmenopausal women: effects of phase I periodontal treatment

BACKGROUND: The aim of this study was to determine how estrogen status may possibly influence gingival crevicular fluid (GCF) alkaline phosphatase (ALP) levels in estrogen-deficient (ED) and -sufficient (ES) postmenopausal women at baseline (BL) and 1 year after periodontal phase I treatment (AT). METHODS: Thirty-six postmenopausal women on estrogen supplements (mean serum estradiol levels >30 pg/ml; estrogen sufficient) and 37 postmenopausal women not on estrogen supplements (mean serum estradiol levels <30 pg/ml; ED) were divided into two subgroups as chronic periodontitis and clinically healthy controls after clinical and radiographic examination. The ES group consisted of 19 control (ES/C) and 17 chronic periodontitis (ES/P) patients, and the ED group consisted of 20 control (ED/C) and 17 chronic periodontitis (ED/P) patients. Plaque (PI) and gingival (GI) indices, bleeding on probing (BOP), probing depths (PD), clinical attachment loss (CAL) scores, and GCF samples were recorded at BL and AT. The levels of ALP in the GCF were measured photometrically. The paired samples Student t and Wilcoxon tests were used to compare the ALP levels and clinical parameters between BL and AT. The correlation among the ALP and clinical parameters was analyzed using the Pearson correlation. RESULTS: The mean of all clinical parameters (PI, GI, BOP, PD, and CAL) was significantly (P <0.05) higher in periodontitis groups (ES/P and ED/P) than controls (ES/C and ED/C). Periodontitis groups (ES/P and ED/P) demonstrated significantly increased GCF volumes and GCF ALP levels (P <0.05) compared to controls (ES/C and ED/C). There were no significant differences in the concentrations of ALP between periodontitis and control groups (P >0.05). The BL GCF ALP total levels of the ED/P group were significantly higher than the ES/P group (P <0.05). The BL and AT serum ALP levels of the ED/P group were not significantly but were numerically higher than the ES/P group. One year after periodontal treatment, the GCF volume, GCF ALP total, and concentrations decreased significantly in both periodontitis groups (P <0.05). However, the GCF ALP levels were still numerically higher in the ED/P group. A positive statistical correlation was found between total ALP levels and PD (r = 0.621; P <0.05). CONCLUSION: These data suggest that the presence of ALP in GCF is not simply a reflection of the local inflammation state and that a patient's estrogen status may possibly influence local ALP levels in GCF.
