Efficacy of surgical versus conservative treatment in esophageal perforation: a systematic review of case series studies

PURPOSE: To evaluate the efficacy of surgical treatment for esophageal perforation. METHODS: A systematic review of the literature was performed. We conducted a search strategy in the main electronic databases such as PubMed, Embase and Lilacs to identify all case series. RESULTS: Thirty three case series met the inclusion criteria with a total of 1417 participants. The predominant etiology was iatrogenic (54.2%) followed by spontaneous cause (20.4%) and in 66.1% the localization was thoracic. In 65.4% and 33.4% surgical and conservative therapy, respectively, was considered the first choice. There was a statistically significance different with regards mortality rate favoring the surgical group (16.3%) versus conservative treatment (21.2%) (p<0.05). CONCLUSION: Surgical treatment was more effective and safe than conservative treatment concerning mortality rates, although the possibility of bias due to clinical and methodological heterogeneity among the included studies and the level of evidence that cannot be ruled out.

Conservative Treatment of Odontogenic Myxoma

Odontogenic myxomas (OMs) are nonencapsulated rare benign tumors that can occur in gnathic bones. They are locally invasive and have a high recurrence rate. Radiologically, OMs show a multilocular (in the majority of cases) or unilocular radiolucency, with either distinct or poorly defined margins. Histopathologically, OMs are characterized by spindle-, wedge-, or stellate-shaped cells loosely arranged in an abundant mucoid background. Myxomas are mainly asymptomatic. Radical surgery, excision, and enucleation followed by curettage of the surrounding bony tissue have all been advocated as treatment options. This study presents a successful case of conservative treatment of OMs with a 5-year follow-up.

Conservative treatment of a radicular cyst in a 5-year-old child: A case report

The present report describes the management of a radicular cyst in a 5-year-old child. The treatment comprised extraction of the primary teeth involved followed by marsupialization. A removable appliance with a resin extension penetrating into the cystic cavity was used to help decompress the lesion. This treatment allowed rapid healing of the lesion and eruption of the permanent incisors without the need for orthodontic treatment.

Conservative treatment of patients with periapical lesions associated with extraoral sinus tracts

This paper describes the clinical courses of three cases with extra-oral sinus tract formation, from diagnosis and treatment to short-term follow-up and evaluation. All teeth involved had periradicular radiolucent areas noted on radiographic examination and extra-oral sinus tracts appearing on the chin with exudation and unpleasant aesthetic appearance. The adopted treatment protocol included treating the sinus tract surface simultaneously with the root canal therapy. After root canal shaping using 5.25% sodium hypochlorite solution, calcium hydroxide-based pastes associated with different vehicles were inserted into the root canal for 4 months, and were changed monthly. All the sinus tracts healed in 7 to 10 days. The apical lesions were completely repaired in a maximum period of 24 months. The treatment adopted provided a complete healing of the periapical lesions in a short follow-up period. Surgical repair of the cutaneous sinus tract was therefore unnecessary. © 2007 The Authors.

Oncological Safety of Autologous Fat Grafting after Breast Conservative Treatment: A Prospective Evaluation

Autologous fat graft to the breast is a useful tool to correct defects after breast conservative treatment (BCT). Although this procedure gains popularity, little is known about the interaction between the fat graft and the prior oncological environment. Evidences of safety of this procedure in healthy breast and after post-mastectomy reconstruction exist. However, there is paucity of data among patients who underwent BCT which are hypothetically under a higher risk of local recurrence (LR). Fifty-nine patients, with prior BCT, underwent 75 autologous fat graft procedures using the Coleman's technique, between October 2005 and July 2008. Follow-up was made by clinical and radiologic examination at least once, after 6 months of the procedure. Mean age was 50 +/- 8.5 years, and mean follow-up was 34.4 +/- 15.3months. Mean time from oncological surgery to the first fat grafting procedure was 76.6 +/- 30.9months. Most of patients were at initial stage 0 (11.8%), I (33.8%), or IIA (23.7%). Immediate complication was observed in three cases (4%). Only three cases of true LR (4%) associated with the procedure were observed during the follow-up. Abnormal breast images were present in 20% of the postoperative mammograms, and in 8% of the cases, biopsy was warranted. Autologous fat graft is a safe procedure to correct breast defects after BCT, with low postoperative complications. Although it was not associated with increased risk of LR in the group of patients studied, prospective trials are needed to certify that it does not interfere in patient's oncological prognosis.

Conservative treatment for amelogenesis imperfecta: a case report

Amelogenesis imperfecta is a hereditary condition that can alter the thickness, color, and shape of tooth enamel. Recent adhesive materials and techniques have provided less invasive treatment options. This case report presents the treatment of a patient whose anterior teeth had color alterations, white spots, pits, and shape defects. Using a more conservative technique, the mandibular and maxillary anterior teeth were restored using veneer direct composite restorations. After 6 years, the restorations demonstrated no deterioration, and no pathology was seen in association with the rehabilitation.

Molar incisor hypomineralization (MIH): conservative treatment management to restore affected teeth

The purpose of this study was to evaluate the 12-month clinical performance of glass ionomer restorations in teeth with MIH. First permanent molars affected by MIH (48) were restored with glass ionomer cement (GIC) and evaluated at baseline, at 6 and at 12 months, by assessing tooth enamel breakdown, GIC breakdown and caries lesion associations. The data were analyzed using the chi-square test and actuarial survival analysis. The likelihood of a restored tooth remaining unchanged at the end of 12 months was 78%. No statistically significant difference was observed in the association between increased MIH severity and caries at baseline (p > 0.05) for a 6-month period, or between increased MIH severity and previous unsatisfactory treatment at baseline (p > 0.05) for both a 6- and 12-month period. A statistically significant difference was observed in the association between increased MIH severity and extension of the restoration, involving 2 or more surfaces (p < 0.05) at both periods, and between increased MIH severity and caries at baseline (p < 0.05) at a 12-month period. Because the likelihood of maintaining the tooth structures with GIC restorations is high, invasive treatment should be postponed until the child is sufficiently mature to cooperate with the treatment, mainly of teeth affected on just one face.

Conservative prosthetic-periodontal treatment for molar class iii furcation involvement: Case report

Purpose: The treatment for furcation involvement is a great challenge to the general dentists. Tunneling may be a treatment alternative for class II and III furcation involvements in mandibular molars with large angle separation and great divergence between the mesial and distal roots. This alternative is a conservative treatment that allows a great condition to oral hygiene maintenance by the patient. Thus, the aim of this case report was to describe a conservative and therapeutic treatment modality for the horizontal defect of periodontal tissues in the furcal area with buccal-lingual extension (class III furcation involvement). Case Report: A patient with class III furcation involvement in the first mandibular molar was submitted to root resection and periodontal surgery to expose the clinical crown for the full-coverage restoration with tunnel preparation. Results: The final result of the treatment with tunneled crown was favorable and predictable due to adequate hygiene condition to avoid plaque accumulation and occurrence of root caries. Clinical Significance: A multidisciplinary approach is essential to achieve a correct treatment plan including surgical-periodontal procedures integrated to the prosthetic rehabilitation. Besides, the recommendation for oral hygiene maintenance is essential for the treatment longevity with tunneled crown. © 2011 Nova Science Publishers, Inc.

Conservative Management of a Large Keratocystic Odontogenic Tumor in the Maxilla

Keratocystic odontogenic tumor is characterized by high recurrence rates. Conservative or aggressive management has been suggested as a method of treatment. Decompression is a conservative treatment that has been used in the treatment of large odontogenic cysts. The authors report a case of a 14-year-old patient with a keratocystic odontogenic tumor located in the right maxilla, which was treated by decompression followed by enucleation with curettage. The lesion did not recur on follow-up for 3 years after the enucleation surgery.

Use of botulin toxin in the treatment of diffuse esophageal spasm. A case report

The diffuse esophageal spasm distinguishes from others esophageal disturbs by the symptoms severity and bad results to conservative treatment. This situation requires formal indication to surgical treatment or dilation. In high risk patients this situation becomes a big problem, due to the lack of another therapeutic option. In a patient with this problem we use an endoscopic injection of botulin toxin in cardia with good results in three months follow-up. Despite this short period of observation we believe that the infiltration with botulin toxin in cardia constitutes a valid therapeutic option in treatment of diffuse esophageal spasm.

Traumatic subdural hygromas: Proposed pathogenesis based classification

Background: Traumatic subdural hygroma (TSHy) is an accumulation of cerebrospinal fluid (CSF) in the subdural space after head injury. It appears to be relatively common, but its onset time and natural history are not well defined. Considered a benign epiphenomenon of trauma, the pathogenesis of TSHy is still unclear and many questions remain unanswered. This study adds to the information on TSHy, and proposes a classification based on pathogenesis.Methods: Thirty-four consecutive adult patients with TSHy were analyzed for clinical evolution and serial CT scan, during a period of several months. TSHy diagnosis was based on published CT scan criteria of hypodense subdural collection after trauma, without enhancement and neomembrane, with a minimum distance of 3 mm between the skull and brain. Ventricle size was analyzed by calculating the bicaudate index (BCI). For comparison, the BCI was measured from CT scan at three moments: admission, at time of TSHy diagnosis, and from last CT scan.Results: There were 34 patients, aged between 16 and 85 years (mean 40), half of them were below 40 years. Road traffic crashes were the main cause of head injury. The mean time for hygroma diagnosis was 9 days. Twenty-one patients (61.8%) underwent conservative treatment for TSHy and 13 (38.2%), surgical treatment. TSHy are early lesions and can be detected in the first 24 hours after trauma, usually as small subdural effusion (SSEff). Based on clinical and CT scan findings, we divided the 34 patients into 3 groups, (Ia and Ib) without evident mass effect and (II) with evident mass effect. Group Ia includes patients without ventricle dilation; Ib, patients with associated ventricle dilations.Conclusions: SSEff detected in the first 24 hours posttrauma in our series evolved into TSHy suggesting that this is an early lesion; all THSy were divided in three groups according to the pathophysiologic mechanism. These three groups probably represent a continuum of CSF absorption impairment. Group la represents what most authors consider a simple hygroma, with no impairment on CSF absorption. Group Ib represent the external hydrocephalus form with various degrees of CSF imbalance, and group II were the cases presenting marked mass effect.

Utilização de contrairritante no tratamento da fixação dorsal de patela intermitente em equinos: relato de casos

Em nove equinos atendidos por apresentarem fixação dorsal de patela intermitente, optou-se pela aplicação de 2mL de contrairritante na região subcutânea, ao longo dos ligamentos patelares medial e intermédio. No período de 12 a 48h após a aplicação, os animais apresentaram aumento de volume e de temperatura local, sensibilidade dolorosa à palpação e relutância à locomoção. Após esse período, os sinais clínicos de inflamação e fixação dorsal de patela foram gradativamente diminuindo até o sétimo dia, em sete dos nove animais avaliados. Após a remissão dos sinais de inflamação, dois animais não responderam ao tratamento, sendo necessária a repetição em um dos casos e realização de desmotomia patelar medial no outro. A aplicação de contrairritante foi eficaz na remissão do sinal clínico de fixação dorsal da patela intermitente. Comparativamente às técnicas cirúrgicas para a correção da enfermidade descritas na literatura, o tratamento promoveu melhora precoce dos sinais, curto período de convalescência e praticidade na realização.
