Surgical treatment of pulmonary aspergilloma

The objective of this study was to analyze the outcome of surgical treatment of pulmonary aspergilloma. To that end, we evaluated 14 adult patients so treated between 1981 and 2009 at the Botucatu School of Medicine University Hospital, in the city of Botucatu, Brazil. Data were collected from the medical records of the patients. Ten patients (71%) presented with simple pulmonary aspergilloma, and 4 (29%) presented with complex pulmonary aspergilloma. Hemoptysis was the most common symptom, and tuberculosis was the most prevalent preexisting lung disease. Two patients (14%) underwent surgery on more than one occasion. There were no intraoperative deaths. Half of the patients developed postoperative complications, prolonged air leak and empyema being the most common.

Effect of long-term treatment with insulin and/or acarbose on glomerular basement membrane thickening in alloxan-diabetic rats

Acarbose is a competitive inhibitor of the intestinal alpha-glycosidases, that can delay absorption of intestinal carbohydrates causing their malabsorption. In the present paper we studied the effects of insulin, acarbose and their association on glomerular basement membrane thickening in alloxan-diabetic rats. Twenty-five male and female Wistar rats, approximately 3 months old at the beginning of the experiment, were assigned randomly to each of five experimental groups: normal control rats, alloxan-diabetic control rats, alloxan-diabetic rats treated with acarbose, alloxan-diabetic rats treated with insulin, and alloxan-diabetic rats treated with insulin plus acarbose. Alloxan was administered in a single iv dose of 42 mg/kg body weight. Insulin was given subcutaneously at doses of 18 to 30 IU/kg corrected daily on the basis of glycosuria and ketonuria. Acarbose was given mixed with rat chow in a dose of 50 mg/100 g chow. Body weight, water and food intake and diuresis, as well as blood and urine glucose were determined after 1, 3, 6, 9, and 12 months of treatment. Glomerular basement membrane (GBM) thickening was determined by electron microscopy at the same times. Clear clinical and laboratory signs of severe diabetes, with blood glucose levels above 200 mg/dl and urine glucose above 3000 mg/dl, were observed in all alloxan-diabetic control rats, in all periods of follow-up, whereas administration of insulin or acarbose reduced the blood glucose levels of treated groups. The most satisfactory control of blood and urine glucose was observed in animals treated with both insulin and acarbose. However, diarrhea was observed in diabetic rats treated with acarbose associated or not with insulin. GBM thickening was correlated with age in all groups. Beginning at six months after diabetes induction, the GBM of untreated diabetic rats was significantly thicker (mean +/- SEM, 4.446 +/- 0.45 mm) than that of normal rats (2.977 +/- 0.63 mm). Both insulin and acarbose prevented GBM thickening and their combination induced thickening similar to the age-dependent thickening observed for normal rats of the same age. We conclude that acarbose when combined with insulin may be a good option in the control of diabetes and its renal complications.

Surgical treatment of erythroleukoplakia in lower lip with carbon dioxide laser radiation

Erythroplakia is considered to represent a premalignant condition and is felt to be at high risk to progress to oral cancer development. When the lesion presents with red and white mucosal alterations concomitantly, the term erythroleukoplakia is used. However, in erythroleukoplakia lesions, the red or erythroplakia areas have been shown to be most likely to demonstrate dysplastic changes compared to the white hyperkeratotic areas. We present a case of patient with erythroleukoplakia involving the lower lip that was treating with carbon dioxide laser radiation (CO2) with 0.8 mm focus, 5 W, power density of 2.5 W/cm(2) in continuous. After the surgery, the vaporized surface was protected with a fibrinolisine + chloramphenicol cream. To date, after 6 months, there has been no clinically evident recurrence on the vermilion area. The functional and esthetic results observed were judged to be excellent.

Surgical treatment of ranula with carbon dioxide laser radiation

Ranula is a mucous extravasation cyst which appears as a swelling in the submental and submandibular regions. Several surgical techniques to manage ranula have been described in the literature, these techniques include the CO2 laser radiation excision. Four patients were treated for intraoral ranula in the floor of the mouth by marsupialization with carbon dioxide laser radiation with defocused beam, continuous mode and 4 watts of power. There were no complications and no recurrences have occurred to date. The results showed that carbon dioxide laser radiation gives optimal results with no need for suture and good wound healing.

Ultrastructural and immunocytochemical evaluation of the effects of extracorporeal shock wave treatment in the hind limbs of horses with experimentally induced suspensory ligament desmitis

Objective-To evaluate the effects of extracorporeal shock wave therapy (ESWT) on affected ligaments in the hind limbs of horses with experimentally induced suspensory ligament desmitis by use of ultrasonographic, ultrastructural, and immunocytochemical techniques.Animals-10 horses.Procedure-Suspensory ligament desmitis was induced in both hind limbs of each horse by use of 2 collagenase injections (administered 2 weeks apart) in each suspensory ligament. Two weeks after the second injection, the right hind limb of each horse was treated with ESWT (3 treatments at 3-week intervals)- the left hind limb was not treated (control limb). Periodically during the study, the healing process was monitored ultrasonographically and the proportions of ligaments affected with lesions were assessed. Four weeks after the last ESWT treatment, biopsy specimens were collected from all ligaments for ultrastructural evaluation and immunocytochemical analysis of transforming growth factor beta-1.Results-The difference in the proportion of the lesion-affected ligament between ESWT-treated and control limbs was significant (P < 0.05) from 3 weeks after the second ESWT treatment to the end of the study. Compared with control ligaments, ESWT-treated ligaments had more small, newly formed collagen fibrils and greater expression of transforming growth factor beta-1 4 weeks after the last ESWT treatment was administered.Conclusions and Clinical Relevance-Results have indicated that ESWT appears to facilitate the healing process in horses with experimentally induced hind limb suspensory ligament desmitis.

Assessment of pharmacotherapeutic safety of medical prescriptions for elderly residents in a long-term care facility

The present study aimed to estimate the prevalence of elderly using potentially inappropriate medications (PIM) and with occurrence of potentially hazardous drug interactions (PHDI), to identify the risk factors for the prescription of PIM and to evaluate the impact of pharmaceutical intervention (PI) for the prescription of safer therapeutic alternatives. Therefore, a cross-sectional study was performed in a long-term care facility in São Paulo State, between December/2010 and January/2011. The medical records of the patients >= 60 years old who took any drugs were consulted to assess the pharmacotherapeutic safety of the medical prescriptions, in order to identify PIM and PHDI, according to the Beers (2003) and World Health Organization criteria, respectively. PI consisted of a guidance letter to the physician responsible for the institution, with the suggestions of safer equivalent therapeutics. Approximately 88% of the elderly took at least one drug, and for 30% of them the PIM had been prescribed. Most of the PIM identified (53.4%) act on the central nervous system. Among the 13 different DI detected, 6 are considered PHDI. Polypharmacy was detected as a risk factor for PIM prescription. After the PI there was no change in medical prescriptions of patients who had been prescribed PIM or PHDI. The data suggests that PI performed by letter, as the only interventional, method was ineffective. To contribute it a wide dissemination of PIM and PHDI among prescriber professionals is necessary for the selection of safer treatment for elderly. Additionally, a pharmacist should be part of the health care team in order to help promote rational use of medicines.

LIFE QUALITY of PEOPLE INFECTED BY HIV WITH OR WITHOUT ANTIRETROVIRAL TREATMENT

The "HIV/Aids-Quality of Life" (HAT-Qol) is a specific multifunctional instrument used to measure the life quality of HIV infected persons. It is divided into nine domains: general activity, sexual activity, secrecy about HIV seropositivity, concern about health, financial concern, awareness about HIV, satisfaction with life, issues about medications and belief in the doctor. The current study analyzed the life quality of HIV infected individuals-who attended the DST/Aids Program in Maringa city, Parana state-regarding the use or not of antiretroviral therapy (TARV) and their demographic, epidemiological and clinical characteristics. Data were collected by retrospective analysis from 1,200 medical charts of patients registered in the program. The HAT-Qol instrument was applied before routine medical consultation. One hundred and sixty-nine patients, who had HIV infection confirmed, were divided into two groups, G1 with 118 individuals receiving antiretroviral therapy and G2 with 51 individuals who were not under this therapy.Result analysis, regarding social and demographic characteristics, revealed no difference among responses related to gender, educational degree and sexual option. Age influenced satisfaction with sexual activity and marital status. Regarding HIV awareness, the lowest response index or worst quality of life came from, respectively, men between 50 and 69 years old and patients who did not have regular partners compared with the ones who did. Additionally, it was observed that the time of diagnosis influenced general activities, HIV awareness, concern about health and financial issues, satisfaction with life and topics about medications. The variables were compared in both groups. There was no influence on the use or not of antiretroviral therapy regarding age, sexual activity, HIV diagnosis time and the domains that evaluated general activities, financial concern, awareness of HIV and satisfaction with life. In relation to time of diagnosis, there was an influence only in persons who had been diagnosed two or three years before, in which a lower quality of life was observed among individuals who were not under antiretroviral therapy. It was not possible to compare variables about medication use, HIV plasmatic viral rate ant time of diagnosis, because G2 individuals were not receiving the antiretroviral therapy. Furthermore, no comparison was made regarding marital status and HIV awareness, because there were no married individuals in G2. Thus, the analysis of the results showed that the use of antiretroviral treatment did not influence the life quality of HIV patients studied by the HAT-Qol scale.

Effects of Chronic Physical Activity and of Ultrasound Treatment on Bone Consolidation

The objective of this study was to investigate the effects of ultrasound treatment and physical exercise on the velocity of bone consolidation and resistance to deformation. We performed osteotomy in the upper third of the right tibia of rats. Physical training consisted of swimming 1 h per day with a load of 5% b.w. for 30 days. Therapy with medium-intensity ultrasound was applied daily on the damaged area. Wistar rats were divided into the following groups: osteotomized sedentary animals with no ultrasound treatment (1.OSnUS), osteotomized trained animals with no ultrasound treatment (2.OTnUS), osteotomized sedentary animals with ultrasound treatment (3.OSwUS). and osteotomized trained animals with ultrasound treatment (4.OTwUS). The animals were sacrificed for the following analyses: muscle glycogen, serum alkaline phosphatase at the 5th, 10th, 20th, and 30th days, test of maximum resistance to flexion, rupture flexion and mean tibial rigidity at the 30th day. Muscle glycogen was increased at the 20th day: alkaline phosphatase was elevated at the 5th and 20th days in groups 3.OSwUS and 4.OTwUS. and decreased at the 10th day. Groups1.OSnUS and 2.OTnUS did not show significant variations. In the mechanical resistance tests, we noted that ultrasound therapy and the association of physical activity used in the present study showed significant differences in bone resistance and bone rigidity after 30 days of treatment. These facts suggest that ultrasound or physical activity, or their combination may accelerate the process of bone tissue repair.

Surgical treatment of metachronous metastases in different organs following radical nephrectomy

Renal clear cell carcinoma (RCCC) is a neoplasia resistant to radio and chemotherapy, with surgical treatment being the procedure that is recognized for its curative treatment. This case report demonstrates the success of an aggressive surgical treatment for consecutive and late metachronous metastases following radical nephrectomy. Case report: Asymptomatic 50-year old man. During a routine examination, an incidental mass was found by renal ultrasonography. He underwent right radical nephrectomy due to RCCC in June 1992. During the follow-up metastases were evidenced in cerebellum on the seventh year, and in left lung and pancreas on the eighth year following the radical nephrectomy, with all of them successfully treated by surgical excision. Comments: The surgical excision of consecutive and late metachronous metastases in different organs arising from RCCC is feasible, being a good therapeutic alternative in selected cases.

Amphetamine Poisoning in a Dog: Case Report, Literature Review and Veterinary Medical Perspectives

Amphetamine abuse in human beings has increased, resulting in many reports of toxicity and death. In the US over 4 million people have abused amphetamines at least once, thus small animals are exposed to increased accidental poisoning risk. This report describes an acute amphetamine poisoning in a dog due to ingestion of 15 mg/kg fenproporex, leading to typical signs of catecholamines release and effects in different organ systems. Similar clinical and laboratory findings observed in human beings are reviewed and physiopathogenic mechanisms discussed, as well as the therapeutic approaches available in veterinary medicine.

Argon laser for treatment of benign eyelid tumors

Small lesions located in the skin might be treated using the laser system. The purpose of this is to report the therapy of benign eyelid tumors using argon laser. Forty-four benign eyelid tumors were treated using argon blue-green laser with spot size of 500 μm, power from 1000 to 1200 mW and 0.3 second exposure time. The eyelid tumors were located mainly in the upper eyelid (65.9%) and the skin tag was the most frequent treated lesion (43.2%). The average number of laser shots to treat the lesions was 165. There was not observed any complication and all patients were satisfied with the results. The authors are considering the argon laser a benefit therapeutic method to treat benign tumors located in the eyelids.

Liposomal daunorubicin and dexamethasone as a treatment for multiple myeloma - The DD protocol

Context and Objective: Lipasomial daunorubicin has been used to treat hematological malignancies, including multiple myelomo (MM). The goal was to evaluate efficacy, side-effects and toxicity of liposomal daunorubicin and dexamethasone (DD Protocol). Design and Setting: Prospective study of Sírio-Libonês, São Camilo, Brasil and Alemão Oswaldo Cruz hospitals. Methods: Twenty consecutive patients with active MM received four cycles of liposomal daunorubicin intravenously for two hours (25-30 mg/m 2/day) on three consecutive days per month, with oral dexamethasone, (10 mg every six hours) on four consecutive days three times a month. Results: The male/female ratio was 1:1 and median age 60. Nine patients were stage IIA, ten IIIA and one IIIB. The median from diagnosis to starting DD was 13 months. All patients received four cycles, except one. Fifteen had already received chemotherapy before DD. Responses of > 50% reduction in serum monoclonal paraprotein were observed in six patients after first cycle (30%), six after second (30%) and four after third (20%), while four (20%) did not obtain this. Initially, 17 patients (85%) had anemia: 12 (70%) achieved correction. Progressive disease was observed in three patients (15%), while one had minimal response, four (20%) partial and 12 (60%) complete. Hemotologlical toxicity was acceptable: three patients (15%) had neutrophils < 1,000/mm 3; none had thrombocyfopenia. Gastrointestinal toxicity was mild: nausea (10%), anorexio (15%) and no vomiting. Conclusions: This treatment has mild toxicity and good response rate. It may therefore be feasible before autologous bone marraw transplantation.

Gingival margin alterations and the pre-orthodontic treatment amount of keratinized gingiva

The purpose of this retrospective study was to associate the amount of keratinized gingiva present in adolescents prior to orthodontic treatment to the development of gingival recessions after the end of treatment. The sample consisted of the intra-oral photographs and orthodontic study models from 209 Caucasian patients with a mean age of 11.20 ± 1.83 years on their initial records and 14.7 ± 1.8 years on their final records. Patients were either Angle Class I or II and were submitted to non-extraction orthodontic treatment. Gingival recession was evaluated by visual inspection of the lower incisors and canines as seen in the initial and final study models and intra-oral photographs. The amount of recession was quantified using a digital caliper and the observed post-treatment gingival margin alterations were classified as unaltered, coronal migration of the gingival margin or apical migration of the gingival margin. The width of the keratinized gingiva was measured from the mucogingival line to the gingival margin on the pre-treatment photographs. The teeth that developed gingival recession and those that did not have their gingival margin position changed did not differ in relation to the initial amount of keratinized gingiva (3.00 ± 0.61 and 3.5 ± 0.86 mm, respectively). Paradoxically, teeth that presented a coronal migration of the gingival margin had a smaller initial amount of keratinized gingiva (2.26 ± 0.31 mm). The mean amount of initial keratinized gingiva did not predispose lower incisors and canines to gingival recession.
