Unilateral Condylar Hyperplasia: A Treatment Strategy

Condylar hyperplasia (CH) is a pathologic condition that causes overdevelopment of the condylar head and neck as well as the mandible. Slowly progressive unilateral enlargement of the head and the neck of the condyle causes crossbite malocclusion, facial asymmetry, and shifting of the midpoint of the chin to the unaffected side. The etiology and the pathogenesis of CH remain uncertain. The diagnosis is made by clinical and radiologic examinations and bone scintigraph. A difference in uptake of 10% or more between condyles is regarded as indicative of CH, and the affected condyles had a relative uptake of 55% or more. When the diagnosis of active CH is established, the treatment consists of removal of the growth center by a partial condylectomy. The authors present the case of a 46-year-old male patient with right active type II CH or hemimandibular hyperplasia who underwent a high condylectomy.

Assessment of postoperative pain after unilateral mastectomy using two different surgical techniques in dogs

Background: There are few studies reporting pain and postoperative analgesia associated with mastectomy in dogs. The aim of this study was to evaluate postoperative pain after unilateral mastectomy using two different surgical techniques in the dog.Findings: Twenty female dogs were assigned (n=10/group) to undergo unilateral mastectomy using either the combination of sharp and blunt dissection (SBD) or the modified SBD (mSBD) technique, in which the mammary chain is separated from the abdominal wall entirely by blunt (hand and finger) dissection except for a small area cranial to the first gland, in a prospective, randomized, clinical trial. All dogs were premedicated with intramuscular acepromazine (0.05 mg/kg) and morphine (0.3 mg/kg). Anesthesia was induced with intravenous ketamine (5 mg/kg) and diazepam (0.25 mg/kg), and maintained with isoflurane. Subcutaneous meloxicam (0.2 mg/kg) was administered before surgery. Postoperative pain was evaluated according to the University of Melbourne pain scale (UMPS) by an observer who was blinded to the surgical technique.. Rescue analgesia was provided by the administration of intramuscular morphine (0.5 mg/kg) if pain scores were > 14 according to the UMPS. Data were analyzed using t-tests and ANOVA (P>0.05). There were no significant differences between the groups for age, weight, extubation time, and duration of surgery and anesthesia (P>0.05). There were no significant differences for postoperative pain scores between groups. Rescue analgesia was required in one dog in each group.Conclusions: The two surgical techniques produced similar surgical times, incidence of perioperative complications and postoperative pain. Multimodal analgesia is recommended for treatment of postoperative pain in dogs undergoing unilateral mastectomy.

Estudo da correlação linear entre a dimensão da largura maxilar e as dimensões das larguras de outras grandezas, lineares, transversas da face, em portadores de fissura transforame incisivo unilateral, através da cefalometria radiográfica, em norma frontal

This research presents the results of a cephalometric radiography study, in frontal norm, that was used to measure the possible linear correlations between several linear dimensions of the face, in a sample of a 140 caucasian brazilians, with an average age of 20 years, who were distributed in 2 groups as follows: Control group - formed of 35 males and 35 females, with no apparent facial deformities and with dental oclusion, not necessarily, in Angle's Class I; Unilateral cleft lip and palate group - formed of 35 males and 35 females with surgical correction of the up in the first year and of the palate until the third year of life, without orthodontic treatment. ln each teleradiography, the following parameters were measured using a computer: - Lateral orbit width or external orbit width (LOe) - Medial orbit width or internal orbit width (LOI) - Zygomatic width or facial width (LZI) - Mastold width (LMa) - Maxilar width (LMx) - Nasal width (LNa) - Condilar width (LCo) - Antigonial width (LGa) The values obtained were treated statistically using quantitative analysis (arithmetic mean, standard deviation, standard mean error, Person's variation factor and Pearson factor linear correlation). Theirs significance was established by Student's t test. The Pearson factor linear correlations determined between transverse linear cephalometric width dimensions of face in frontal norm for individuals of both groups and sex, with an average age of 20 years, were: ...

Negligência unilateral pós-acidente vascular encefálico: atuação da Terapia Ocupacional

Unilateral Neglect Syndrome is one of the consequences of cerebral vascular accident (CVA) generally following right parietal lobe lesion, leading to the impairment of perceptive visual, spatial and attention functions. The patient affected does not realize the environmental stimuli on the contralesional hemibody. Occupational therapy plays an important role in caring for this patient, seeking the recovery of perception, attention and social engagement. This study aimed to describe and evaluate the results of occupational therapy intervention and treatment in a single Unilateral Neglect Syndrome post CVA patient. Data were obtained from a survey of the patient’s medical records and interviews of his therapist and caretaker. The analysis of the patient’s medical records and his therapist’s report showed that the patient responded satisfactorily to treatment, presenting a decrease of the left unilateral neglect at the end of the study period. The favorable outcome of the patient outlined the relevance of evaluating the effects of Occupational Therapy interventions for clinical unilateral neglect syndrome.

Effects of physiotherapy on balance and unilateral vestibular hypofunction in vertiginous elderly

Background: We aimed to analyze the effect of a physical therapy protocol on unilateral vestibular hypofunction and overall balance in elderly with vertigo. Methods: The study included nine subjects, four male subjects (68.5 ± 11.09 years old) and five females (72.4 ± 7.09 years old). It was used the performance-oriented Mobility Assessment (POMA), to evaluate the balance and the Unterberger – Fukuda test for analysis of unilateral vestibular dysfunction through rotations and displacements of the body. We developed and applied a structured physical therapy protocol, consisting of group exercises. Results: It was observed that after the protocol, all participants improved balance (33.9 ± 5.1 vs. 47.3 ± 7.6, p < 0.0001) and displacement (111.1 ± 38.0 vs. 53.3 ± 34.6, p = 0.0001). However, it was not found significant differences for rotation. Conclusion: The proposed protocol has contributed to an improvement in balance and vestibular dysfunction of the aged.

Sonographic findings in unilateral hydronephosis in a jaguarundi Puma yagouaroundi - case report

A jaguarundi (Puma yagouaroundi) was sent to the diagnostic imaging sector for an abdominal ultrasound. In the present report, we observed a marked dilation of the left kidney, with anechogenic content and the presence of echogenic lines extending from the capsule towards the center of the kidney, sonographic evidence that indicates the diagnosis of hydronephrosis.

Treinamento de força unilateral: efeitos sobre a taxa de desenvolvimento de força do membro contralateral

The aim of this study was to analyze the effects of unilateral isokinetic strength training at high speed (180°.s-1) of the dominant leg on the rate of force development (RFD) of the contralateral limb. The study included 18 male individuals, apparently healthy, with an average of 23 years, and without regular practice of physical activities. The subjects were divided randomly into two groups: control group (GC) and isokinetic group (GISOC). Assessments were made of the values of peak isometric torque (PT isom) and RFD of both lower limbs in the pre-training. So, the GISOC underwent an isokinetic strength training with high speed (180°.s-1) for 6 weeks, with the dominant leg only and then reassessed. It was found that there was no significant improvement in value of PT isom (p> 0.05), and the RFD for the dominant limb had a significant improvement (p< 0.05) compared to the pre-training and that there was no transfer of values to the contralateral side (p> 0.05). It can be concluded that the isokinetic training at high speed was not enough for significant cross education

Cardiovascular and autonomic alterations in rats with parkinsonism induced by 6-OHDA and treated with L-DOPA

Evaluate the effects caused by L-DOPA on cardiovascular and autonomic parameters in an animal model of Parkinsonism induced by 6-hydroxydopamine (6-OHDA).Adult male Wistar rats were subjected to bilateral microinfusion of 6-OHDA or saline (sham group) in the substantia nigra, and treated by gavage with L-DOPA or water for 7days after surgery. On the 6th day the rats were subjected to femoral artery catheterization for cardiovascular recording. Mean arterial pressure (MAP) and heart rate (HR) were evaluated at baseline and during head up tilt (HUT) protocol. Spectral analysis of cardiovascular variability was performed using the V2.4 CardioSeries software v2.4. The lesion was quantified by dopamine levels in the striatum.Dopamine levels in the striatum were decreased in 6-OHDA rats (sham: 4.79±0.49ng/mg; 6-OHDA: 1.99±0.68ng/mg) and were not recovered by Prolopa treatment. Baseline values of MAP and HR were not different between groups. HUT induced an increase in MAP and HR (ΔMAP: 17±1mmHg, ΔHR: 39±4bpm) that were attenuated in 6-OHDA and in Prolopa treated animals. At baseline, the systolic arterial pressure (SAP) variance was lower in the 6-OHDA and sham Prolopa groups. Spontaneous baroreflex sensitivity was higher at baseline in the 6-OHDA group as compared to all studied groups.Our data suggest that treatment with Prolopa did not interfere with cardiovascular variables at baseline. However, during HUT, the 6-OHDA and Prolopa control animals presented a lower cardiovascular compensation, suggesting a possible autonomic impairment in Parkinsonism induced by 6-OHDA.
