Objectives The aim of the study was to describe renal pelvis (RP) and ureteral ultrasonographic measurements in a population of cats with confirmed benign ureteral obstruction (UO) by antegrade pyelography. The secondary objective was to further describe clinical findings associated with minimally dilated obstructed kidneys in an attempt to better understand its occurrence. Methods Retrospective case series of cats diagnosed with benign UO were confirmed by antegrade pyelography. Medical records were reviewed and signalment, diagnostic imaging results, serum creatinine (SCr) concentration and urine culture results were recorded. Each obstructed kidney was categorized into two groups: group 1 included all RP measurements ⩽4 mm and group 2 included all RP measurements >4 mm. Results A total of 82 cats with 114 obstructed ureters met the inclusion criteria. Fifty (61%) cats had a unilateral UO and 32 (39%) had a bilateral UO. Thirty (26%) kidneys were included in group 1 while 84 (74%) were included in group 2. Nine (8%) kidneys had an RP dilation ⩽2 mm. Median RP and ureteral diameters were 6.6 mm (range 1.1–37.0 mm) and 3.2 mm (range 0.0–11.0 mm), respectively. RP size correlated positively with ureteral diameter in the study population ( P <0.0001), but not in group 1 when analyzed separately ( P = 0.47). UO was secondary to stones in 80 (70%) ureters. Seventeen (21%) cats had a positive urine culture. At admission, 79 (96%) cats were azotemic with a median preoperative SCr concentration of 444 µmol/l (range 108–1326 μmol/l). The mean (95% confidence interval [CI]) preoperative SCr concentration was significantly higher in group 1 (762 µmol/l [498–1165 μmol/l]) than in group 2 (409 µmol/l [333–502 μmol/l]). RP size in the two groups correlated negatively with preoperative SCr concentration ( P = 0.0002). Conclusions and relevance Feline UO may be associated with minimal RP dilation and the severity of RP and ureteral dilation can be highly variable. Absence of significant RP dilation does not rule out UO in cats.

Abstract Background Failed back surgery syndrome (FBSS) is a common problem affecting 20–40% of cases undergoing spine surgeries. Spinal cord stimulation (SCS) has been shown to be an efficient and relatively safe treatment in managing many intractable chronic pain syndromes. Objectives This study compares the efficacy and safety of MR-compatible sensor driven-position adaptive SCS and conventional SCS in treating FBSS. Methods This is a retrospective case series of 120 consecutive FBSS patients who underwent SCS between February 2011 and March 2018. Pain levels, analgesic/opioid use, and sleep problems were assessed before and 3 months after the procedure in patients who received either conventional SCS (group 1; n = 62) or sensor-driven position adaptive SCS (group 2; n = 34). The degree of patient satisfaction, the change in the activities of daily living (ADLs) together with the rate of complications were compared in both treatment groups. Results The two treatment groups were homogenous at baseline. Patients in both groups improved significantly regarding pain, opioid consumption, sleep, and ADLs. The magnitude of improvement was statistically higher in group 2. An absolute reduction of 6 points on the VAS in patients who received position adaptive SCS vs a 3.3 point reduction in conventional SCS cases (p < 0.0001). Half of the patients in group 2 (n = 17) showed excellent satisfaction after the procedure versus 14.5% of cases in group 1 (n = 9). Conclusion SCS is an efficient and reliable treatment in FBSS. MR-compatible sensor driven-position adaptive SCS can be a more effective treatment in this patient group.

Background: Traumatic brain injury is a severe condition in elder patients. Young patients usually have better prognosis compared to the elderly. Head trauma might represent an initial event that leads to death in this population. Objective: To evaluate was to evaluate the epidemiological profile of elderly patients operated on chronic subdural hematoma (CSDH). Methods: This is a descriptive, observational and retrospective case series. The use of anticoagulant and antiplatelet drugs, length of hospital stay, mortality and CSDH recurrence, among others, were the evaluated variables. Results: A total of 328 patients had their records assessed. Patients younger than 60 years formed group 1 (n=102) and those older than 60 years formed group 2 (n=226). Ageing is correlated to higher mortality. Acetylsalicylic acid and anticoagulant drugs usage in both groups did not correlate to worse outcomes. In group 2, there were 33 deaths during hospital stay (14.6%) and 14 deaths within one year after surgery (6.2%). Only one death was registered in group 1. Conclusion: Ageing is an important isolated prognostic factor.

Alpha-1 antitrypsin deficiency (AATD) accounts for approximately 5% of lung transplants (LTx) performed annually. No studies have addressed the potential benefit of ongoing alpha-1 proteinase inhibitor (A1-PI) replacement to AATD patients post-LTx. Our primary objective was to assess potential benefits of continually administering A1-PI from pre- to post-transplantation for AATD LTx recipients. A retrospective case series was performed on AATD LTx recipients between 2002 and 2018. Data reviewed included date of A1-PI initiation, pulmonary function tests, and surveillance bronchoscopies. Endpoints included the change of forced expiratory volume in one-second (FEV1), infective episodes, chronic lung allograft dysfunction (CLAD), and acute rejection episodes. Out of the 13 AATD LTx recipients, 6 continually received A1-PI beginning prior to transplant (Group 1), and 7 were re-introduced to Α1-PI a number of years after LTx (Group 2). After two years, Group 1 experienced a median FEV1% predicted decline of 0.0%, and Group 2 experienced a median decline of 15.0%. No differences noted in frequency of infective episodes. One patient in Group 1 developed CLAD about 2.5 years post-LTx, whereas all Group 2 patients developed CLAD at a mean of 5.4 years post-LTx. No Group 1 patients experienced acute lung rejection episodes noted from surveillance bronchoscopies, corresponding data not available for Group 2. We report that the continual use of Α1-PI in AATD LTx recipients is associated with better maintenance and stabilization of lung function and potentially less acute lung rejection episodes early post-LTx. Prospective studies should be performed to confirm possible benefits.

Purpose To investigate the length of time required for diagnosing consecutive esotropia rather than initial overcorrection and examine risk factors for persistent postoperative esotropia after intermittent exotropia surgery. Methods This is a retrospective case series in a tertiary medical center. Fifty consecutive patients with postoperative esotropia ≥6 prism diopters at 1 week following exotropia surgery, managed with nonsurgical management and followed up for more than 6 months from 2014 to 2015, were included. Patients were allocated to 1 of 2 groups depending on whether the postoperative esotropia was resolved at 1 month after surgery. Patients with ongoing nonsurgical management were reevaluated monthly. Timing that significant resolution occurred was assessed. Clinical characteristics and motor and sensory successes were evaluated at 6 months after surgery. Results Thirty-two patients were allocated to group 1 and 18 to group 2. Significant resolution occurred between 1 week and 1 month after surgery. Patients were older and preoperative deviation at distance was larger in group 2 than in group 1 (p = 0.006 and 0.015). A significantly larger proportion of patients in group 2 showed combined vertical deviation (p = 0.019). Motor and sensory success rates were comparable. Conclusions When initial postoperative esotropia persists for more than 1 month, it should be regarded as consecutive esotropia. Older age, a larger preoperative deviation, and concurrent vertical deviation are risk factors for persistent postoperative esodeviations. Therefore, more postoperative attention should be given to these patients.

Abstract Background The continuation of anti-vascular endothelial growth factor (anti-VEGF) treatment after achieving stability in patients with neovascular age-related macular degeneration has generally been advocated. In our own patients, we thought to assess whether continued anti-VEGF treatment is capable of preventing recurrences. Methods In this retrospective observational case series, patients with stable disease either opted to continue treatment every 12–14 weeks (Group 1) or stopped treatment with subsequent follow-up visits every 8–12 weeks (Group 2). Results Of the 103 eyes of 103 patients achieving stability, 49 eyes continued treatment (Group 1), whereas treatment was stopped in 54 eyes undergoing regular follow-up (Group 2). Recurrent disease was observed in 21 (42.9%) and 33 (61.1%) cases in Group 1 and Group 2, respectively (p = 0.08). Time between achieving stable disease and recurrence was comparable between Group 1 and Group 2 (11.1 ± 8.2 months vs. 9.2 ± 6.7 months; p = 0.43). The number of visits between achieving stability and disease recurrence was similar, but not the number of injections (3.5 ± 2.0 vs. 0.2 ± 0.4; p < 0.001). Conclusions Continuing anti-VEGF therapy after achieving functional and morphological stability every 12–14 weeks does not prevent recurrences. Patients deserve to be informed of a potential lifetime risk of recurrences, even under continued therapy.

Summary Objective: To compare the effects of bandaging on immediate postoperative swelling using a modified Robert-Jones bandage after tibial plateau levelling osteotomy (TPLO) in dogs. Study design: Prospective case series. Methods: Dogs undergoing a TPLO were randomly placed into two groups. Group 1 received a modified Robert-Jones bandage postoperatively for a 24 hour period and Group 2 was not bandaged. Hindlimb circumference was measured at the level of the mid-patella, the distal aspect of the tibial crest, the midpoint of the tibial diaphysis and the hock. Measurements were recorded and compared in each group preoperatively and at 24 hours and 48 hours post-operatively. Interobserver variability was compared between the two observers. Results: There was no significant difference in postoperative swelling, as measured by the percentage change in circumference, between bandaged and unbandaged operated limbs after the TPLO at 24 and 48 hours at any site. Some significant differences in measurement at particular sites were observed between the two different observers, but there was a significant linear correlation at all sites between observers. The observer with the least experience consistently had slightly higher measurements at these sites. Clinical relevance: The use of a modified Robert-Jones bandage after TPLO did not prevent statistically significant postoperative swelling, and thus may not be indicated for this purpose. Postoperative bandages placed to control swelling after other small animal orthopaedic procedures should be evaluated individually for efficacy.

Schirmer Tear Test

Objectives The aim of this study was to describe the clinical findings, diagnostic test results and response to therapy of cats with Schirmer tear test 1 (STT-1) values below the reference interval. Methods The medical records of three institutions were searched for cats with ocular surface disease and STT-1 values <9 mm/min, confirmed at two or more separate visits. Results Ten cats (17 eyes) were included. The mean ± SD (range) age and STT-1 values in affected eye(s) were 6.1 ± 5.7 (0.2–16) years and 2.4 ± 3.1 (0–8) mm/min, respectively. Concurrent ocular surface disease was bilateral in 5/10 cats. Clinical signs included conjunctivitis (14/17 eyes), corneal ulceration (6/17 eyes), non-ulcerative keratitis (4/17 eyes), symblepharon (4/17 eyes), eosinophilic keratitis (3/17 eyes), corneal sequestrum (3/17 eyes), corneal fibrosis (2/17 eyes) and meibomitis (2/17 eyes). Management included: topically applied lacrimomimetics, antiviral drugs, corticosteroids or immunomodulatory drugs; orally administered famciclovir; or surgical procedures, in various combinations. Response to therapy (defined as an increase in STT-1 value of ⩾5 mm/min) was transient (seen at a single reassessment) in 65% of eyes and sustained (seen at ⩾2 consecutive reassessments) in 18% of eyes. Conclusions and relevance Clinical features seen in cats with low STT-1 values are described, although the association between aqueous deficiency and the reported ocular changes is unknown at this time. We encourage clinicians to assess the tear film in cats with ocular surface disease, and initiate therapy with lacrimomimetics if STT-1 values are repeatedly below normal. Such information will further define aqueous tear deficiency in cats, providing a better understanding of disease prevalence, pathogenesis and treatment.

Background: Acute bacterial nephritis is an infectious process diagnosed through imaging studies. The clinical course of the disease has been shown to be more aggressive than acute pyelonephritis. It continues to be underdiagnosed, thus there are few studies on the entity in the literature. Objective: To describe the clinical characteristics and imaging features of acute bacterial nephritis, as well as its clinical course. Design: A descriptive, retrospective case series was conducted. Materials and methods: Thirty-two cases of acute bacterial nephritis in patients admitted to the hospital within the time frame of 2009 to 2016 were reviewed. The patients’ clinical characteristics upon admission were registered, as well as inpatient clinical progression, culture results, and antibiotic therapy response. The imaging studies were re-evaluated and the diagnostic consistency with either the focal or multifocal disease presentation was confirmed. Results: Cases predominated in women (n=29, 90.62%) and the most frequently associated comorbidities were diabetes (n=16, 50%) and obesity (n=9, 28.25%). The most important clinical findings upon admission were fever (n=15, 46.87%) and leukocytosis (n=27, 84.38%). Escherichia coli was the most commonly isolated bacterium (63.63%). Both acute focal bacterial nephritis and acute multifocal bacterial nephritis were observed in 46.87% (n=15) and 53.13% (n=17) of the patients, respectively. Imaging studies were required for all diagnoses. Conclusion: Fever and leukocytosis are the main findings in acute bacterial nephritis. Imaging studies are necessary for making the diagnosis, given that acute pyelonephritis and acute bacterial nephritis cannot be clinically differentiated.

Purpose. To evaluate the effectiveness and safety of Ologen implantation versus conjunctival autograft transplantation for primary pterygium. Methods. A retrospective case-series analysis. Thirty-one eyes of 29 patients were included in the Ologen group and 42 eyes of 35 patients in the autograft group. The patients were followed up for 1 year and evaluated for slit-lamp biomicroscopy, intraocular pressure, and adverse events. Recurrence rate, complications, and final appearance of the cases were evaluated prospectively. Result. At 1 year after operation, 2 eyes recurred (6.5%) in the Ologen group and 4 eyes recurred (9.52%) in the autograft group. There was no statistically significant difference between both groups (P=0.157, χ2 = 3.781). There was no occurrence of serious complications. Two eyes among the 31 eyes of the Ologen group were conjunctivitis; the incidence of complications was 6.45% (2 eyes). There was conjunctivitis in 3 eyes of the autograft group, 1 eye complicated with symblepharon, and 1 eye with conjunctival granuloma; the incidence of complications was 11.90% (5 eyes), and there was no statistically significant difference between both groups (P=0.094). The conjuntiva was less vascular and inflamed at 1 month postoperatively in the Ologen group than in the autograft group. Conclusions. Ologen transplantation was technically easier, provided short operative time compared with conjunctival autograft transplantation, and preserved healthy conjunctiva with less complication and less recurrence; it may be a new, safe, and effective alternative for improving the short-term success rate of primary surgery.
