Laparoscopic adhesiolysis in a mini pony

Background: Intraperitoneal adhesions are common in equines, especially following exploratory celiotomy. Adhesiolysis is the treatment of choice for patients presenting postsurgical adhesions. Laparoscopic approach for adhesiolysis presents several advantageous aspects in human patients. The aim of the current study was to report a case of successful laparoscopic adhesiolysis in a mini pony horse. Case: A male Shetland Pony, weighing 140 kg, was admitted under complaint of right hind limb trauma and treated surgically for metatarsal fracture reduction. The patient has also had intermittent episodes of colic and was always treated clinically without major complications. The pony had no history of previous abdominal surgery and no episodes of acute abdomen were seen during hospital stay. Three months following ostheosynthesis, an exploratory laparoscopic approach was carried out to assess the possible cause or consequences of the episodes of acute abdomen. The patient was submitted to general anesthesia, positioned in dorsal recumbency and the abdomen was clipped and aseptically prepared for surgery. During the laparoscopic inspection, there were adhesions involving the ventral abdominal wall and a ventral mesogastric segment of duodenum. Laparoscopic adhesiolysis was performed using a two-port approach, by gently breaking the adhesion bands using meticulous traction with a 10-mm laparoscopic atraumatic Babcock forceps. Afterwards, the intestinal loop was rinsed with heparin sodium solution diluted in normal saline. The pneumoperitoneum was completely drained and the trocars sequentially withdrawn from the abdominal wall. The synthesis of the muscular layer was carried out using an interrupted cross mattress pattern, followed by synthesis of the skin with an interrupted cushion pattern. Total surgical time was 58 min. the patient was able to recover without complications. In the early postoperative period, the surgical recovery was considered excellent. No apparent adhesion involving the previously affected intestinal loop was found during the ultrasound exam following 15 days of surgery. Furthermore, the surgical wounds had healed completely, with no complications. Discussion: In the current case report, the primary cause of the acute abdomen episodes was not determined since the patient had never undergone abdominal surgery. It was hypothesized that an acute inflammation of the duodenal loop that was involved by the adhesion bands may have triggered the adhesiogenesis. Laparoscopy was efficient and presented a short operative time, due to magnification of image and adequate observation of structures surrounded by adhesion bands. Although the use of Babcock forceps is not usually recommended for adhesiolysis in the current literature, it was both effective in manipulating the bowel and performing the adhesiolysis. The heparin solution diluted in normal saline was effective in preventing the recurrence of new adhesions, which was evidenced by ultrasonography following 15 days. The laparoscopic approach usually minimizes the new formation of adhesions as trauma to the peritoneal surfaces is minimized by the use of delicate instruments, as observed in the current study. In addition, laparoscopy reduces the possibility of contact among the peritoneal surfaces and foreign bodies, such as gauze, glove powder and room air particles. Moreover, it maintains the abdominal surfaces in adequate humidity environment.

Effects of constant rate infusion of anesthetic or analgesic drugs on general anesthesia with isoflurane: A retrospective study in 200 dogs

Constant rate infusion (CRI) shows several advantages in balanced anesthesia, such as reduction of requirement for inhaled anesthetics and control of pain. The most commonly used drugs in these protocols are local anesthetics, dissociative, and opioids, which may be administered alone or in combinations. We evaluated the records of 200 dogs that underwent various surgical procedures with anesthetic or analgesic CRI in the perioperative period during 2011 and 2012 at the Veterinary Hospital of Franca University (Unifran), and identified possible complications during the transoperative period. Records evaluated included clinical state, laboratory tests, drugs used in premedication and induction, and CRI protocol. Acepromazine and morphine were the main drugs used in premedication. Propofol was used to induce anesthesia alone or in combination with other agents. We evaluated records of the 25 different CRI protocols. Fentanyl was the main drug employed in CRI, either alone or in combination. There were 128 episodes of anesthetic complications during CRI;the most common were hypotension, hypertension, and tachycardia, which occurred in 43 (32%), 35 (26.3%), and 19 (14.2%) dogs, respectively. Cardiac arrhythmia was reported in only 4 dogs. Signs of respiratory depression were present in dogs treated with 6 different CRI protocols. The consumption of isoflurane (vol %) reduced between 15.7% and 21.05% after 30minutes of the CRI in the fentanyl and fentanyl-lidocaine-ketamine CRI groups (p<0.05). In conclusion, CRI is a valid component of balanced anesthesia in dogs, safe, and has a low incidence of adverse effects. However, future studies are warranted to describe the results of the clinical use of CRI to better characterize and refine this technique.

The employment situation in Latin America and the Caribbean: Countercyclical policies for a sustained recovery in employment

Latin America and the Caribbean experienced an unexpectedly vigorous economic recovery in 2010 after the output contraction of 2009. This upturn was reflected in the region’s employment and unemployment rates, which resumed the positive trends that had been broken by the crisis, and formal wages rose slightly. The strength of the recovery and labour-market performance varied markedly across subregions and countries, however. The first part of this joint ECLAC/ILO publication on the employment situation in Latin America and the Caribbean looks at how labour markets have responded to the rapid economic upswing in 2010 and early 2011, highlighting both the significant advances achieved in the post-crisis period and the sharp differences evident across subregions and countries. As well as tapping into the improved external conditions which followed upon the Asianled global economic upturn, several Latin American countries were also able to contain the impacts of the crisis and underpin their own recovery with countercyclical policies, thanks to the leeway gained by their macroeconomic management during the run of growth from 2003 to 2008. These countries were in a position to implement expansionary fiscal and monetary policies, some of which channelled higher fiscal spending through labour-market policies or softened the impact of the crisis on employment and income, as discussed in previous ECLAC/ILO bulletins. Since the region is fairly new to the use of countercyclical policies, the second part of this document reviews the experiences arising from those policies and considers lessons for institutionalizing them. Economic growth in the Latin American and Caribbean region has historically been marked by the volatility of its economic cycles, with high-growth periods being succeeded by deep crises. Volatility has conspired against the use of production resources over extended periods and short growth horizons have impeded investment in capital and labour. In the recent international crisis, the deployment of countercyclical macroeconomic policy helped to reduce the depth and duration of the impact and to leverage a more rapid recovery. It is therefore worth looking at the fundamentals of a long-term countercyclical macroeconomic policy which would provide the tools needed to deal with future crises and pave the way for economic growth that may be sustained over time. A special factor during this crisis was that a greater effort was made to support employment and income. Several of the labour-market policy measures taken acted as vehicles for conveying increased fiscal spending to individuals, reflecting greater consideration for equality concerns. Indeed, these measures were aimed not only at stabilizing andstrengthening domestic demand per se, but also at preventing the crisis from hitting lowest-income households the hardest, as had occurred in previous episodes. And —again unlike the pattern seen in previous episodes— inflation actually fell during the crisis as the high food and fuel prices seen in the run-up to it eased as a result of both existing macroeconomic policies and global conditions. This averted the surge in inequality so often seen in previous crises. Two caveats must be added, however. First, not all the countries were in a position to deploy strong countercyclical policies. Many simply lacked the fiscal space to do so. Second, some countries took this sort of measure more as an ad hoc response to the crisis than as part of a clearly established countercyclical policy strategy. The challenge, then, is to institutionalize a countercyclical approach throughout the economic cycle. Taking up this challenge is part of making economic growth more sustainable. This year —2011— was ushered in by rapid economic growth and substantial improvements in labour indicators. With the region’s GDP projected to grow well over 4% this year, ECLAC and ILO estimate that the regional unemployment rate will fall substantially again, from 7.3% in 2010 to between 6.7% and 7.0% in 2011.

Enriched environment contributes to recovery of visual acuity and increases perineuronal nets in monocular-deprived animals

ABSTRACT The aim of the present study was to analyze the influence of enriched environment on the distribution of perineuronal nets (PNNs) using a stereogically based unbiased protocol and visual acuity in adult Swiss albino mice that underwent monocular deprivation during the critical period of postnatal development. Eight female Swiss albino mice were monocular deprived were removed and cut at 70 µm thickness in a vibratome and processed for lectin histochemical staining with Wisteria floribunda agglutinin (WFA). Architectonic limits of area 17 were conspicuously defined by WFA histochemical staining, and the optical fractionator stereological method was applied to estimate the total number of PNNs in the supragranular, granular, and infragranular layers. All groups were compared using Student's t-test at a 95% confidence level. Comparative analysis of the average PNN estimations revealed that the EE group had higher PNNs in the supragranular layer (2726.33 ± 405.416, mean ± standard deviation) compared with the SE group (1543.535 ± 260.686; Student's t-test, p = .0495). No differences were found in the other layers. Visual acuity was significantly lower in the SE group (0.55 cycles/degree) than in the EE group (1.06 cycles/degree). Our results suggest that the integrity of the specialized extracellular matrix PNNs of the supragranular layer may be essential for normal visual acuity development.

Progressive recovery of a tropical deforested stream community after a flash flood

AIM: In this study, we evaluated and compared community attributes from a tropical deforested stream, located in a pasture area, in a period before (PRED I) and three times after (POSD I, II, and III) a flash flood, in order to investigate the existence of temporal modifications in community structure that suggests return to conditions previous to the flash flood. METHODS: Biota samples included algae, macrophytes, macroinvertebrates, and fish assemblages. Changes in stream physical structure we also evaluated. Similarity of the aquatic biota between pre and post-disturbance periods was examined by exploratory ordination, known as Non-Metric Multidimensional Scaling associated with Cluster Analysis, using quantitative and presence/absence Bray-Curtis similarity coefficients. Presence and absence data were used for multivariate correlation analysis (Relate Analysis) in order to investigate taxonomic composition similarity of biota between pre and post-disturbance periods. RESULTS: Our results evidenced channel simplification and an expressive decrease in richness and abundance of all taxa right after the flood, followed by subsequent increases of these parameters in the next three samples, indicating trends towards stream community recovery. Bray-Curtis similarity coefficients evidenced a greater community structure disparity among the period right after the flood and the subsequent ones. Multivariate correlation analysis evidenced a greater correlation between macroinvertebrates and algae/macrophytes, demonstrating the narrow relation between their recolonization dynamics. CONCLUSIONS: Despite overall community structure tended to return to previous conditions, recolonization after the flood was much slower than that reported in literature. Finally, the remarkably high flood impact along with the slow recolonization could be a result of the historical presence of anthropic impacts in the region, such as siltation, riparian forest complete depletion, and habitat simplification, which magnified the effects of a natural disturbance.

Changes in heart period during endodontic treatment

Background: Tooh extraction was demonstrated to increase sympathetic modulation of the heart, however, it is not understood the effects of endodontic treatment on cardiac autonomic regulation. We evaluated heart rate variability (HRV) during endodontic treatment. Method: 50 male and female patients aged between 18 and 40 years old and diagnosed with irreversible pulpitis or pulp necrosis of the lower molars with indication of gender endodontic treatment were analyzed. HRV was analyzed in the time (SDNN, RMSSD, pNN50) and frequency (LF, HF and LF/HF ratio) domains recorded in the first session of root canal treatment. The indices were analyzed in the following periods: T1) ten minutes before the endodontic treatment, T2) ten minutes after the administration of anesthesia before endodontic treatment, T3) during the entire period of endodontic treatment and T4) thirty minutes after the end of the endodontic treatment. Results: The SDNN, RMSSD and pNN50 indices increased at T2 compared to T1, the pNN50 and RMSSD indices increased at T3 and T4 compared to T2. The LF in normalized units increased at T4 compared to T2 and in absolute units it was increased at T4 compared to T1. The HF in normalized units was reduced at T4 compared to T2 and in absolute units was reduced at T1, T3 and T4 compared to T2. The LF/HF ratio was higher at T4 compared to T2. Conclusion: The global modulation of heart increases after local anesthesia and vagal tone reduce during surgery procedures and after the surgical procedures.

Two-stage rumenostomy in buffaloes

Background: Rumenostomy may be performed for therapeutic and digestibility research purposes in bovines, small ruminants and camelids. Several studies requires romenostomy in buffaloes in order to sample ruminal content for laboratorial assays. However, complications and outcome of rumenostomy was poorly studied in buffaloes. Therefore, the aim of the current study was to describe a two-stage rumenostomy technique in buffaloes, focused on intra and post-operative period.Materials, Methods & Results: Nine Murrah buffaloes were submitted to a 36-h and 12-h of food and water fastening. The animals were given acepromazine and maintained in standing position. Flank local anesthesia was carried out. A circular skin incision was carried out in the center of the left flank, followed by divulsion of the external and internal obliques and transversus abdominus muscles, and incision of the peritoneum. Subsequently, a segment of the dorsal aspect of the rumen was grasped and pulled through the flank incision. The rumen was attached to the peritoneum and skin incision margins in four points (dorsal, ventral, cranial and caudal). Additional simple interrupted sutures attaching the rumen serosa to the skin were applied subsequently. Four additional interrupted horizontal mattress sutures were applied equidistantly, taking bites only in the skin and rumen serosa. Following 12 h, the second stage was carried out. The buffaloes were prepared and restrained as performed for the first stage. A circular flap was excised from the exteriorized rumen and the silicone romenostomy cannula was placed. Clinical parameters, postoperative recovery, weight and behavioral pain scale were assessed. Positioning and anesthesia regimen were adequate for the achievement of the procedure. However, two animals fell in the restraint chute during the first surgical stage. Mild ischemia of the exteriorized rumen segment was observed on the second surgical stage, which resulted in less hemorrhage and enhanced cannula positioning. Complete cicatrization and permanent adhesion of the rumen to the skin were achieved. No ruminal leakage to the abdominal cavity occurred. No signs of pain were reported. There were few cases of laxity of the romenostomy opening leading to drop of cannula, myiasis on the margin of the stoma site and few cases of mild ruminal content leakage on the long-term assessment.Discussion: Restraint in standing position was considered adequate, although lateral recumbence constitutes another option. However, higher risk of contamination and technical difficulties in placing the cannulas are expected if lateral recumbence is considered. In other trials using acepromazine, no accidental recumbence occurred. Xylazine was also indicated for chemical restraint of buffaloes. It is known that flexible cannulas provide better anatomic adjustment and adaptation as well as being effective for sampling ruminal content, as seen in the current study. Ruminal leakage is one of the most frequent complications of romenostomy, which may affect animal's welfare. The animals in the current study presented no variations on the body score, even though on those presenting cannula loosening or ruminal content leakage. Moreover, no significant changes of the ruminal content parameters were noticed. Myiasis was also reported following ruminal surgical interventions, which were mainly attributed to extensive breeding. Loss of the cannula, subcutaneous emphysema and suture dehiscence are common complications of romenostomy. Nonetheless, none of those complications were found on the current study. Thus, romenostomy was feasible and efficient for sampling and performing assays of the ruminal content in buffaloes.

Cutaneous sensibility impairmentafter mandibular sagittal split osteotomy: a prospective clinical study of the spontaneous recovery

Purpose The aim of this prospective study was to objectively evaluate the inferior alveolar nerve (IAN) sensory disturbances in patients who underwent sagittal split ramus osteotomy (SSRO) and its spontaneous recovery and to define the incidence of sensibility loss, time, and area at which the recovery occurs. Patients and Methods Clinical evaluation of the IAN sensory disturbance was undertaken preoperatively and at the first week, fourth week, 2 months, and 6 months postoperatively in 30 patients who underwent SSRO at the Oral and Maxillofacial Surgery Division of the Araraquara Dental School--Unesp and at the Plastic Surgery Division of the Medical Sciences School--Unicamp. The 30 patients were examined at all periods regarding the IAN functionality by Semmes-Weinstein testing. Results The mean age of the patients included in this study was 29.36 years old. All patients showed sensibility loss at the 7-day evaluation time. The comparison between sides, gender, and age did not show any significant difference. In most of the examined zone, the data collected at 6 months were statistically similar to the data collected at the preoperative period. All zones presented significant recovery, starting from 30 days after surgery. Twenty patients had total spontaneous recovery at the final period, in all examined zones. Conclusions The SSRO presents the disadvantage of temporary paresthesia; however, spontaneous nerve function recovery does occur. The Semmes-Weinstein test is a reliable, inexpensive, and easy-to-apply tool, which can be used for clinical evaluation on a daily basis at offices and hospitals.

Avaliação algimétrica por estímulo nociceptivo térmico e pressórico em cães pré-tratados com levomepromazina, midazolam e quetamina associados ou não ao butorfanol ou buprenorfina

This study aimed at quantifies the pain in dogs under dissociative anesthesia, across thermal and pressoric stimulus and quantify the reasonable period between two different opioids analgesics. In this study, 30 dogs were used and, divided into three groups of 10 animals each, in which the animals of GI received methotrimeprazine and midazolam put on the same syringe with ketamine. The animals of GII received the same treatment of GI but associated with butorphanol and finally the animals of GIII received the same treatment of GI but associated with buprenorphine. The routine parametric evaluations has been proceeded, although using the thermo algimetry measured in degrees C with the average of 52 degrees C and the pressoric algimetry in Kg. In the thermo algimetry, there has been significant difference in GI at the moments M0, M1, M4 and M5; in GII it was found at M0, M1, M5 and M6 and in GIII it was observed the significant at M0 and M1. It has also been shown in pressoric algimetry significant difference in GI at the moments M0, M2 and M3. Among GII it has observed significant difference at all moments and it has found at M0, M9 in GIII. Thus, it has observed significant differences between all groups; for such the M2 of GII smaller than the others; and M4, M5 of GIII bigger than GI and GII. In the assessment of all periods it was observed significant latent period bigger in GI, however, with reasonable period and short recovery in GII and GIII. In the order hand, the postural tonus recovery it was longer in GIII, followed by GII and finally GI. The used method for the measurement of algic stimulus was efficient, noticing a reasonable analgesic period of 3 hours for butorphanol and 6 hours for buprenorphine.
