Low plasma taurine levels in English cocker spaniels diagnosed with dilated cardiomyopathy.

OBJECTIVES: The aims of this study were to evaluate taurine levels in English cocker spaniels with dilated cardiomyopathy and assess their survival time and natural progression of their disease. MATERIALS AND METHODS: Retrospective comparison of English cocker spaniels with dilated cardiomyopathy phenotype with and without taurine deficiency at the cardiology department of a UK academic referral centre between 2008 and 2018. RESULTS: Taurine plasma concentration was available in 16 English cocker spaniels with dilated cardiomyopathy phenotype; 13 of 16 had congestive heart failure and three of 16 did not. Taurine concentration was low (<50 µmol/L) in 13 of 16 and normal in three of 16. Deficient dogs received taurine supplementation in addition to conventional cardiac medications. Eight dogs were still alive at the end of this study and eight were dead. MST for all dogs included in the study was 2800 days. Left ventricular systolic function improved and left ventricular dimensions reduced in English cocker spaniels with taurine deficiency following taurine supplementation and conventional cardiac therapy, although similar results were observed in English cocker spaniels with normal taurine concentration on cardiac therapy alone. CLINICAL SIGNIFICANCE: Based on laboratory reference intervals, low taurine concentrations were common in English cocker spaniels with dilated cardiomyopathy, showing a possible association between dilated cardiomyopathy in English cocker spaniels and taurine deficiency; supplementation with taurine was not curative.

Obesity, bariatric surgery and periodontal disease: a literature update.

Obesity is linked to other systemic diseases, such as diabetes mellitus, dyslipidemia, and arterial hypertension. These comorbidities increase the risk of developing cardiovascular disease risk. Adipose tissue is a true endocrine organ and releases various pro-inflammatory cytokines. Periodontal disease (PD) is a chronic inflammatory disorder of the gingiva and bone support (periodontal tissues) that surrounds the teeth. The relationship between obesity and an increased risk of developing PD is already known in the literature. Many studies correlated the cardiometabolic risk with periodontal disease. Bariatric surgery is a way to reduce the adipose tissue in obese patients, that meet specific criteria. It has been observed that this type of surgery usually reduces both the systemic inflammation and the cardiometabolic risk. Some authors have hypothesized that, as a result, the progression of periodontal disease is also reduced. Five articles are analyzed in this systematic review. In these papers, the periodontal health before and after the bariatric surgery was compared. However, the conclusion of the previous studies demonstrated a scarce literature and did not confirm the reduction of periodontal disease after bariatric surgery, but a reduction of cardiometabolic risk. Therefore, periodontal disease in no way influences the reduction of cardiovascular risk after bariatric surgery.

Low-level laser therapy in the treatment of muscle-skelet pain in patients affected by temporo-mandibular disorders.

BACKGROUND: The purpose of the study is to evaluate the effectiveness of Low-Level Laser Therapy in reducing joint and muscle pain in patients with acute and chronic temporomandibular dysfunction. MATERIALS AND METHODS: The study was conducted on a sample of 180 patients. The sample was divided into two groups according to the time of onset of the disease: acute TMD (<6 months) and chronic TMD (> 6 months). The treatment for all patients provided for the irradiation with Diode Laser Wiser Doctor Smile with tip plane wave at wavelength of 830 nm, continuous beam to 40nW diameter and radius of 6 mm. The irradiated areas were the joint area, temporal, masseter and pterygoid. The irradiation time for each zone was 60s.The protocol adopted consisted of two weekly treatment for six weeks. Pain assessment was performed using the Visual Analog Scale (VAS), in which different scores (s) depending accused of pain by the patient: s0 no pain, s1-3 mild pain, s4-6 moderate pain, s7-9 severe pain and s10 excessive pain. The pain monitoring was performed before treatment, after 15 days and after one month. RESULTS: The sample included 80 patients with acute TMD and 100 with chronic TMD. The sample belonging to acute TMD group before treatment, was distributed as follows: 0% in s0; 12,5% in s1-3; 31.3% in s4-6; 53.6% in s7-9 and 2.5% in s10. After 15 days the distribution was was as follows: 6.25% in s0; 47.5% in s1-3; 20% in s4-6; 26.3% in s7-9 and 0% in s10. After 30 days the sample was well distributed: 35% in s0; 45% in 1-3; 10% in s4-6; 10% in s7-9 and 0% in s10. The sample belonging to the chronic TMD group, at time zero, was as follows: 0% at s0; 48% in S1-3; 35% in s4-6; 15% in s7-9 and 2% in s10. After 15 days the distribution was: 29% in s0; 28% in S1-3; 33% in s4-6; 10% in s7-9 and 0% in s10. After 30 days the sample was well distributed: 45% in s0; 36% in S1-3; 15% in s4-6; 4% in s7-9 and 0% in s10. CONCLUSIONS: The Low-Level-Laser-Therapy is a valuable tool that can significantly decrease the perception of pain in patients with temporomandibular joint dysfunction, acute and chronic.

Polysonographical evaluation in a case of moderate osas treated with mandibular advancement device.

BACKGROUND: The Obstructive Sleep Apnea Syndrome (OSAS) is a clinical picture characterized by partial or complete obstruction of the upper airway during sleep, associated with a reduction of oxygen saturation in the blood.The most common symptoms are: apnea sleep, snoring, headache, sleepiness, reduced concentration and memory, irritability, increased blood pressure and dry mouth. MATERIALS AND METHODS: It was examinated a not-smoker man of 54 years that suffers of roncophaty. He did physical examination, rhinoscopyexam, faringoscopy, rhinofibrolaringoscopy, gnathological evaluation and polysomnographic examination performed with multichannel polygraphy (VitalNight). From the performed examinations, it has been diagnosed a moderate form of obstructive apnea sleep syndrome. He was treated with a mandibular advancement device and it was repeated the polysomnographic exam. RESULTS: Comparing the results of the polysonographic examination performed before and after the treatment, the patient's clinical picture clearly improved. It has shown a clear reduction of obstructive apneas, hypopneas and snoring. CONCLUSIONS: The use of a mandibular advancement device is certainly a valuable aid in the treatment of moderate type OSAS. The quality of diurnal life is also improved as shown with Sleepness Epworth Scale.

Statistical analysis of the frequency distribution of signs and symptoms of patients with temporomandibular disorders.

The purpose of this text is to evaluate the distribution by sex and age of TMD patients and the frequency of pain on palpation of the lateral pterygoid muscle, pterygoid internal, sternocleidomastoid, masseter, temporal. The purpose is also to assess the existence of direct correlations between the articulating click and lateral deviation, the headache and tenderness of the temporal, the back pain and tenderness of the sternocleidomastoid, the postural disorders and difficulty finding the exact mating closing, the disorders related to previous dental procedures (large conservative reconstructions, rehabilitations fixed dentures and dental extractions) and tenderness to the temporal and masseter. 623 medical records, including 451 males and 175 females were randomly selected. It was statistically calculated the F/M ratio, age distribution and frequency of muscle tenderness to palpation through the relationship of positive feedback on the total sample multiplied by one hundred. The correlation between various disorders was calculated by estimating the Mantel-Haenszel common odds ratio. For each result it has been finally calculated the asymptotic level of significance.

Estudo da hipoglicemia em 121 recem-nascidos macrossomicos. / Study of hypoglycemia in 121 macrosomic newborn infants

Neste estudo realizado no Hospital de Clinicas da Faculdade de Medicina de Taubate, no periodo de um ano, analisa-se a incidencia de hipoglicemia em recem-nascidos macrossomicos correlacionando-a com a idade e peso de nascimento. Nos 121 recem-nascidos com peso de nascimento igual ou superior a 4.000 g detectou-se glicemia abaixo de 30 mg% em 24 criancas (19,8%). A maior incidencia de hipoglicemia ocorreu no periodo de 30' a 3h de vida(11 casos, igual a 13,4%). Nao se encontrou correlacao entre maior peso de nascimento e maior incidencia de hipoglicemia. Entre os recem-nascidos com glicemia abaixo de 30 mg%, apenas dois (8,3%) apresentavam sintomas. A maioria dos recem-nascidos considerados como hipoglicemicos no presente estudo (87,5%) apresentava resultados de glicemia compreendidos entre 20 mg% e 30 mg%
