Proximal Urethrostomy Versus Urethroplasty for Complex Urethral Strictures.

Background: The optimal treatment for complex urethral stricture (CUS) is yet to be determined. Comparisons of methods based on validated questionnaires or objective outcome measures are lacking. Objective: To compare proximal urethrostomy and urethroplasty for CUS using objective measures and validated questionnaires, and to evaluate trends in subgroups of patients who underwent proximal urethrostomy as the intended definitive treatment versus first-stage urethroplasty. Design setting and participants: We identified all patients who underwent proximal urethrostomy at our center from 2004 to 2021. The control group comprised patients who underwent urethroplasty for CUS (strictures >6 cm, recurrent posturethroplasty strictures, or CUS due to lichen sclerosus or past hypospadias surgery). Outcome measurements and statistical analysis: The primary outcome was a recurrent stricture at a minimal follow-up of 1 yr. The secondary outcomes included validated questionnaires, uroflowmetry, and residual urine volume. Survival was compared by a Kaplan-Meier analysis. Results and limitations: The study included 57 proximal urethrostomy and 75 urethroplasty patients. Results for these two groups were as follows: the cumulative incidence of stricture recurrence over a median follow-up of 46 mo was 22.6% for proximal urethrostomy versus 36.2% for urethroplasty (p = 0.106); no statistically significant differences were observed between groups in terms of postoperative quality of urination or life, satisfaction with outcome, and erectile function. Both groups had a significant improvement in urinary flow after surgery (19.65 vs 20.29 ml/s), with no difference between the groups (p = 0.796); the proximal urethrostomy group had a significant improvement in postvoid residual after surgery, but there was no difference between the groups in the last follow-up visit (79.16 vs 52.03 ml; p = 0.245). A subgroup analysis of the proximal urethrostomy group showed no significant differences in cumulative primary or secondary outcomes. Limitations included the retrospective design and the relatively small study population. Conclusions: Comparisons of the two groups revealed no significant differences in stricture recurrence, results of validated questionnaires, or objective measures of urination. Patient summary: Proximal urethrostomy is equivalent to urethral reconstruction, and it should be offered as a viable solution for complex urethral stricture.

The impact of germline BRCA pathogenic variants in locally advanced, triple negative breast cancer treated with platinum-based neoadjuvant chemotherapy.

BACKGROUND: Whether germline BRCA (gBRCA) pathogenic variants (PV) affect prognosis of women with triple negative breast cancer (TNBC) and whether it has implications for treatment decisions in the neoadjuvant setting is unclear. METHODS: This is a retrospective two-center cohort study comprising all women with early stage TNBC who have completed genetic testing and were treated with neoadjuvant dose-dense doxorubicin and cyclophosphamide followed by paclitaxel and carboplatin. All eligible patients treated between 10.2014 and 3.2020 were included. Data on clinico-pathological, pathological response, overall survival (OS) and disease-free survival (DFS) were evaluated. Differences in clinico-pathological features and outcomes were analyzed according to gBRCA status. RESULTS: Sixty-four women were included in the final analysis, of which 31 had gBRCA PV (gBRCA carriers) and 33 were gBRCA wild-type. Clinico-pathological characteristics were similar between both groups. The odds for pathological complete response (pCR) were significantly higher in gBRCA carriers (74.2%) compared to BRCA wild-type women (48.5%), p = 0.035. At a median follow-up of 30 months, gBRCA carriers had significantly favorable OS (HR = 8.64, 95% CI 1.08-69.21, p = 0.042). The difference in DFS did not reach statistical significance (HR = 7.4, 95% CI 0.91-60.27, p = 0.062). The favorable OS for gBRCA carriers remained significant in multivariate analysis (p = 0.029) and was noted regardless of pathological response (p = 0.018). CONCLUSION: Compared to wild-type, gBRCA carriers with locally advanced TNBC treated with neoadjuvant chemotherapy containing carboplatin had a higher pCR rate and better outcomes. These results strengthen the contention that gBRCA status should be considered when tailoring treatment decisions in women with locally advanced TNBC.

Dermatological adverse events under programmed cell death-1 inhibitors as a prognostic marker in metastatic melanoma.

Melanoma is widely treated with programmed cell death-1 (PD-1) inhibitors. As part of their anti-tumor immunity effect, they increase the susceptibility to cutaneous immune-related adverse events (cIRAE) among other autoimmune effects. To characterize the manifestations of cIRAE in melanoma patients treated with PD-1 inhibitors, and evaluate the correlation with tumor response. A retrospective study of 95 metastatic malignant melanoma patients treated with PD-1 inhibitors at the Hadassah Medical Center during 2013-2016. The most common cIRAE was pruritus reported by 39 (41%) patients. All other cIRAE were noted in 34 patients (35.8%), of which the most common cutaneous manifestation was vitiligo, demonstrated in 17 patients (17.9%) followed by various rashes (7.4%, including erythema multiforme, oral lichen planus, photosensitive rash, insect bite-like reaction, and urticaria), psoriasiform rash (3.2%), bullous pemphigoid (3.2%), and eczema (1%). Interestingly, higher response rates to immunotherapy were demonstrated in patients who developed pruritus (85%) and cIRAE (88%), with lower mortality rates in the cIRAE group (38.2%) versus the non-cIRAE group (70.5%, p = 0.002). cIRAE are common among malignant melanoma patients treated with PD-1 inhibitors and may be a marker for favorable prognosis.

The Timing of Limb Amputation in Nontraumatic Patients: Impact on Mortality and Postoperative Complication Rates.

Diabetes and peripheral vascular diseases are accompanied frequently by lower limb ischemia and in minority, need for amputation, as a treatment of last resort. Even after a decision has been made regarding amputation, the procedures are often repeatedly postponed due to more urgent surgeries and lack of operating room availability. This study assessed the possible relationship between the duration of time inpatients wait for semiurgent amputations and the incidence of postamputation complications. A retrospective cohort, including all 360 adult patients who underwent nontraumatic limb amputation due to an ischemic/gangrenous/infected foot in a single center during an 11-year period (2007-2017). Most (96%) of the procedures were major amputations. The mean waiting time until amputation was 3 ± 5 days. Mortality during hospitalization occurred in 101 (28%) patients and re-amputation in 38 (11%). The duration of antibiotic treatment was 11 ± 14 days. The rate of sepsis was 30% (107/360). There was no significant difference between the duration of time until amputation and mortality during hospitalization: among those who waited ≤48 hours, the mortality rate was 27% (60/224) and among those who waited >48 hours 30% (41/136) (p = .5). Patients waiting ≤48 hours had higher re-amputation rates than those waiting >48 (31/223 (14%) vs 7/136 (5%), p = .009). Mortality was associated significantly to patients' age and renal function. Correlation was found between the waiting time until amputation (≤48 or >48 hours) and the rates of in-hospital mortality, sepsis, duration of antibiotic treatment and overall duration of hospitalization. Re-amputation rate was higher in group with the shorter waiting time. This correlation may be explained by the fact that patients who needed urgent amputation had a more extensive and severe disease, and thus tended to require more re-amputation operations.

Outcomes of sublobar resection vs lobectomy for invasive clinical stage T1N0 non-small-cell lung cancer: A propensity-match analysis.

BACKGROUND: The role of sub lobar resection (SLR; either segmentectomy or wedge resection) vs lobectomy (LBCT) for invasive clinical stage T1N0 non-small-cell-lung-cancer (NSCLC) has not been fully established yet. AIM: We aimed to characterize the preoperative parameters leading to selecting SLR and compare the overall survival (OS) and disease-free survival (DFS) of these two surgical approaches. METHODS: Clinical data on 162 patients (LBCT-107; SLR-55) were prospectively entered in our departmental database. Preoperative parameters associated with the performance of SLR were identified using univariate and multivariate cox regression analysis. The Kaplan-Meier method was used to compute OS and DFS. Comparison between LBCT and SLR groups and 32 propensity-matched groups was performed using Log-rank test. RESULTS: Median follow-up time for the LBCT and SLR groups was 4.76 (Inter-quartile range [IQR] 2.96 to 8.23) and 3.38 (IQR 2.9 to 6.19) years respectively. OS and DFS rates were similar between the two groups in the entire cohort (OS-LBCT vs SLR P = .853, DSF-LBCT vs SLR P = .653) and after propensity matching (OS-LBCT vs SLR P = .563 DSF-LBCT vs SLR P = .632). Specifically, Two- and five-year OS rates for LBCT and SLR were 90.6.% vs 92.7%, 71.8% vs 75.9% respectively. Independent predictors of selecting for SLR included older age (P < .001), reduced FEV1% (P = .026), smaller tumor size (P = .025), smaller invasive component (P = .021) and higher American Society of Anesthesiology scores (P = .014). CONCLUSIONS: In 162 consecutive and 32 matched cases, SLR and lobar resection had similar overall and disease-free survival rates. SLR may be considered as a reasonable oncological procedure in carefully selected T1N0 NSCLC patients that present with multiple comorbidities and relatively small tumors.

Severity of shock, rate of physiological stabilization and organ failure in healthy women admitted to the intensive care unit following major peripartum hemorrhage: A retrospective, descriptive study.

PURPOSE: To describe shock severity, physiological stabilization and organ failure in healthy women admitted to the intensive care unit (ICU) after major peripartum hemorrhage (PPH). MATERIALS AND METHODS: Retrospective, descriptive, single center study. RESULTS: Twenty-nine women median age 33 years (interquartile range [IQR] 30-36) and gravidity 5 pregnancies (IQR 3-9) were studied. One woman died. The median maternal admission hematocrit was 28.8 (IQR 25.7-32.4). Median transfusion rates were nine units of packed red blood cells (IQR 7-12.25), eight fresh frozen plasma (IQR 6-12), 17 platelets (IQR 10-22) and 15 cryoprecipitate (IQR 9.75-20). Blood pressure dropped significantly in the six hours following ICU admission. Nonetheless, lactate decreased from 3.23 mmol/L to 1.54 mmol/L within 24 h of ICU admission, renal and pulmonary function were unaffected and coagulopathy was never observed. Two-thirds of the women underwent hysterectomy. One-third underwent repeated surgery. The median length of ICU stay was <48 h and that of mechanical ventilation was <24 h. Increased transfusion rates correlated with lengthier ICU admission (p ≤ 0.01 regardless of blood product). CONCLUSIONS: Ongoing hemorrhage in women with severe PPH manifests subtly and often requires active intervention. Hemorrhage control is required to achieve physiological stabilization and minimize organ damage.

Parameters associated with sperm quality prior to chemotherapy in lymphoma patients.

Sperm quality in lymphoma patients may be reduced even prior to initiation of chemotherapy. The objective of this study was to examine the relationship between lymphoma prognostic factors and sperm quality prior to chemotherapy. A retrospective cohort study was conducted in a Hadassah Medical Center sperm bank and the Hematology department. The cohort included 101 Hodgkin's and 90 non-Hodgkin's lymphoma patients that underwent sperm cryopreservation before chemotherapy between 1998 and 2015. Known lymphoma prognostic factors were compared between patients with normal and impaired sperm parameters. The Prognostic Score Ratio (PSR), an index representing the number of negative lymphoma prognostic measures that found in a lymphoma patient, was additionally calculated and compared between the groups. Among the prognostic factors of lymphoma, the following factors were found to be associated with impaired sperm parameters-low albumin (p < 0.001) and haemoglobin (p < 0.001) levels, B symptoms (p = 0.021) and PSR (p < 0.001). Logistic regression showed significant association of albumin and haemoglobin with reduced sperm quality (OR = 2.7 and OR = 13.5, p < 0.05; respectively). To conclude, low albumin and haemoglobin levels are related to reduced sperm quality. The linkage between these prognostic factors and sperm quality may be related to a general inflammatory status.

Cluster analysis based clinical profiling of Idiopathic Pulmonary Fibrosis patients according to comorbidities evident prior to diagnosis: a single-center observational study.

BACKGROUND: The characterization and clinical profiling of people affected by Idiopathic Pulmonary Fibrosis (IPF), based on clinical events occurring prior to the diagnosis of the fibrotic disease, may facilitate the understanding of events and comorbidities that occur before the diagnosis of IPF and aid in identifying patients at an earlier stage of the disease. METHODS: In this observational study, a cohort of 96 patients, obtained from a community-based pulmonary clinic, were studied retrospectively. These patients were diagnosed with IPF between January 2008 and November 2016, based on findings on lung biopsy and/or high-resolution CT. Using clinical data obtained within the five years before diagnosis and the two-step method of cluster analysis, patients were assigned to one of four groups. The distribution of clinical characteristics and comorbidities present prior to diagnosis was analyzed among the clusters. RESULTS: Cluster 1 is composed of male patients, smokers, with ischemic heart disease. Cluster 2 is composed of male patients, smokers with dyspnea at rest, dry cough and prevalent emphysema. Cluster 3 is composed of male patients without other significant comorbidities, half of whom had dyspnea at exertion. Cluster 4 includes female patients only, most of whom never-smokers and the largest portion of patients with hypothyroidism. The majority of patients had basal end-inspiratory crackles at time of diagnosis, equally distributed among clusters. CONCLUSION: Different clinical phenotypes of IPF emerge years before time of diagnosis and if confirmed in larger cohorts may help in forming diagnostic algorithms that would allow earlier diagnosis of IPF.

The association between video-nystagmography and sensory organization test of computerized dynamic posturography in patients with vestibular symptoms.

OBJECTIVE: Vertigo is a complex symptom which imposes diagnostic and treatment challenges. Laboratory evaluation of vertigo includes video-nystagmography (VNG) and computerized dynamic posturography (CDP) for the evaluation of different aspects of this complaint. There are vague indications for each test and potential disagreements between them. The aim of this study is to examine the association between the test results of the VNG and sensory organization test (SOT) of CDP in patients referred for both vestibular tests. METHODS: Retrospective data regarding 56 patients age 17-82 years were collected. Patients suffered vestibular complaints and were referred for VNG and CDP evaluation on the same day. The level of agreement between VNG (including caloric test) and the vestibular input of the SOT for each patient was calculated. RESULTS: Among the study group, 10 showed abnormal caloric test results, of which 3 (5.4%) had normal vestibular input in the SOT, and 7 (12.5%) had impaired input (p = 0.724). Spontaneous nystagmus was recorded in 13 patients by VNG, of which 2(3.6%) had normal vestibular input and 11(19.6%) had impaired vestibular input (p = 0.056). CONCLUSIONS: This study shows no statistically significant association between the VNG test and SOT test results. Our results emphasize the difference between the tested aspects in each laboratory test, and the need to define specific indications for each of them. There is a marginally significant association between impaired vestibular input and spontaneous nystagmus, demonstrating the non-localizing nature of this sign.

Saliva Real-Time Polymerase Chain Reaction for Targeted Screening of Congenital Cytomegalovirus Infection.

BACKGROUND: Saliva real-time polymerase chain reaction (PCR) was shown to be sensitive and specific for the detection of congenital cytomegalovirus (cCMV) in universal screening studies. In the current study, we assessed the performance of saliva real-time PCR in newborns undergoing targeted cCMV screening. METHODS: Saliva real-time PCR results were prospectively correlated with reference-standard urine detection in newborns undergoing targeted cCMV screening over a 3-year period, in successive validation (concurrent testing of all saliva and urine specimens) and routine-screening (confirmatory urine testing of positive saliva results) implementation phases. RESULTS: The sensitivity, specificity, and positive and negative predictive values of saliva real-time PCR were 98.3% (95% confidence interval, 90.8%-99.9%), 91.5% (89.3%-93.3%), 45.6% (36.7%-54.7%), and 99.9% (99.2%-99.9%), respectively, in 856 concurrently tested newborns. True-positive saliva real-time PCR detection (defined in relation to urine detection) was associated with earlier saliva sampling (P = .002) and a higher saliva viral load (P < .001). We further identified a saliva viral load cutoff value that reliably distinguished between true-positive and false-positive saliva results. CONCLUSIONS: In newborns undergoing targeted screening for cCMV, saliva real-time PCR is highly sensitive yet has a low positive predictive value, necessitating confirmatory testing. Early sampling and application of a validated viral load cutoff could improve the assay performance and support its large-scale implementation in this growing clinical setting.

Bleeding Risk Assessment and the Role of Primary Hemostasis Screening in Patients Undergoing Kidney Biopsy.

BACKGROUND: Risk factors for bleeding complications after percutaneous kidney biopsy (PKB) and the role of primary hemostasis screening are not well established. OBJECTIVES: To determine the role of primary hemostasis screening and complication outcomes among individuals who underwent PKB. METHODS: We reviewed data of 456 patients who underwent PKB from 2010 to 2016 in a large university hospital. In 2015, bleeding time (BT) testing was replaced by light transmission aggregometry (LTA) as a pre-PKB screening test. RESULTS: Of the 370 patients who underwent pre-PKB hemostasis screening by BT testing, prolonged BT was observed in 42 (11.3%). Of the 86 who underwent LTA, an abnormal response was observed in 14 (16.3%). Overall, 155 (34.0%) patients experienced bleeding: 145 (31.8%) had minor events (hemoglobin fall of 1-2 g/dl, macroscopic hematuria, perinephric hematoma without the need for transfusion or intervention) and 17 (3.7%) had major events (hemoglobin fall > 2 g/dl, blood transfusion or further intervention). Abnormal LTA response did not correlate with bleeding (P = 0.80). In multivariate analysis, only prolonged BT (P = 0.0001) and larger needle size (P = 0.005) were identified as independent predictors of bleeding. CONCLUSIONS: Bleeding complications following PKB were common and mostly minor, and the risk of major bleeding was low. Larger needle size and prolonged BT were associated with a higher bleeding risk. Due to the relatively low risk of major bleeding and lack of benefit of prophylactic intervention, the use of pre-PKB hemostasis screening remains unestablished.

Fetal Urine Production Rate in Preterm Premature Rupture of Membranes Is Associated with Adverse Neonatal Outcome: A Pilot Study.

AIM: In this study, we evaluate the associations between fetal urinary production rate (FUPR), measured by ultrasound, and adverse neonatal outcome in women with preterm premature rupture of membranes (PPROM). METHODS: We conducted a prospective pilot cohort of singleton pregnancies complicated by PPROM occurring at gestational week 24 or later managed until spontaneous labor (after 48 h of admission), chorioamnionitis, or induction by protocol at 35 + 0 weeks. FUPR was evaluated by 2D sonography at admission (corrected for gestational age). The main neonatal outcome measures were chorioamnionitis, placental inflammatory grading, first neonatal creatinine value, first neonatal dextrose value, length of neonatal intensive care unit (NICU) stay, necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH) (grades I-IV), blood transfusions, reduced neonatal urine production rate (<4 mL/kg/h), and early neonatal sepsis. Samples of maternal (at admission) and umbilical cord blood were analyzed for interleukin-6 (IL-6) level. RESULTS: The study included 38 women. Low FUPR was associated with clinical chorioamnionitis, longer NICU hospitalization (p = 0.01), higher rates of NEC or IVH (p = 0.008), and blood transfusion (p = 0.004). CONCLUSIONS: A finding of FUPR on in utero ultrasound examination in pregnancies complicated by PPROM may be indicative of adverse neonatal outcome.

Global hemostasis in healthy bitches during pregnancy and at different estrous cycle stages: Evaluation of routine hemostatic tests and thromboelastometry.

This study assessed the global hemostasis (including prothrombin time [PT], activated partial thromboplastin time [aPTT], antithrombin activity [ATA], fibrinogen and d-Dimer concentrations, platelet count, plateletcrit and thromboelastometry) in healthy pregnant bitches, comparing the results with those of healthy bitches at different estrous cycle stages, and assessed whether hemostatic changes during pregnancy are associated with serum progesterone concentration or the presence of fetuses in utero. The results show that pregnant bitches have higher fibrinogen concentration, platelet count and platelatecrit, and that fibrin and global clot formations occur faster than in non-pregnant bitches at different estrous cycle stages. Additionally, clot strength was higher in pregnant bitches than in non-pregnant ones. There were no differences in PT, ATA, and D-dimer concentration between all study groups. The aPTT was significantly shorter in bitches at the fourth and last pregnancy weeks, compared to the anestrus group, and shorter in both the fourth and last pregnancy weeks groups, compared to diestrus group. These results all support a hypercoagulable state in healthy pregnant bitches, unassociated with progesterone concentration.

Intratesticular and incisional line infiltration with ropivacaine for castration in medetomidine-butorphanol-midazolam sedated dogs.

OBJECTIVE: To evaluate whether intratesticular and incisional ropivacaine infiltration produces sufficient intra- and postoperative analgesia for castrating dogs under sedation. STUDY DESIGN: Randomized, blinded, controlled clinical study. ANIMALS: Twenty-three healthy dogs weighing 5.8-35.6 kg admitted for castration. METHODS: Dogs were sedated with medetomidine (0.01 mg kg-1), butorphanol (0.2 mg kg-1) and midazolam (0.2 mg kg-1) intramuscularly, and were randomly assigned to group R, 0.2-0.4 mL kg-1 of ropivacaine 0.5%, or group S, an equivalent volume of saline injected intratesticularly and along the incision line. If persistent motion was observed during surgery, sedation was considered to be insufficient and general anaesthesia was induced. Carprofen 2.2 mg kg-1 was administered postoperatively. Pain was evaluated in all dogs before sedation and postoperatively following atipamezole administration at 1, 2, 4, 8 and 24 hours using an interactive visual analogue scale (IVAS; 0-100), the Glasgow composite pain scale-short form (CMPS-SF; 0-24), and a mechanical algometer. Methadone 0.3 mg kg-1 was administered intravenously to dogs if IVAS >30 or CMPS-SF >4. RESULTS: There was no significant difference between groups for the number of dogs administered general anaesthesia. The time from the beginning of surgery to induction of general anaesthesia was significantly shorter [median (range)] in group S [6 (3-25) minutes] than in group R [56 (36-76) minutes]. At 8 hours IVAS was significantly higher in group S (14 ± 10) than in group R (6 ± 4). CONCLUSIONS AND CLINICAL RELEVANCE: Intratesticular and incisional ropivacaine infiltration delayed the time to anaesthesia induction, and provided analgesia after castration performed under deep sedation in dogs. Intratesticular local anaesthesia can be an important part of the anaesthetic plan for castration.

The effects of topical parasympatholytic drugs on pupil diameter and intraocular pressure in healthy dogs treated with 0.005% latanoprost.

PURPOSE: Prostaglandin analogs induce miosis and lower intraocular pressure (IOP). As pupils of latanoprost-treated eyes may have to be dilated for ophthalmoscopy or intraocular surgery, we studied whether 0.5% tropicamide or 1% atropine alter the effects of 0.005% latanoprost on pupil diameter (PD) and IOP in healthy dogs. METHODS: IOP and PD were measured hourly, 8 AM-4 PM, with the right and left eyes serving as control (CE) and treated (TE) eyes, respectively. Measurements were conducted in ten Labrador retrievers with one-week washout: (i) baseline values, (ii) latanoprost at 8 AM, (iii) tropicamide at 8 AM, (iv) latanoprost at 8 AM and tropicamide at 11 AM, and (v) latanoprost at 8 AM and atropine at 11 AM (n = 4). RESULTS: At 4 PM, TE PD was 5.88 ± 0.59, 3.62 ± 0.66, 6.33 ± 1.00, 5.42 ± 0.57, and 8.12 ± 1.24 mm in sessions 1-5, respectively. TE PD was significantly different between treatment sessions 2, 4, and 5 (P = 0.018, Friedman), being most mydriatic in session 5. At 4 PM, TE IOP was 11.27 ± 2.07, 7.10 ± 1.07, 11.1 ± 2.21, 7.70 ± 1.85, and 8.87 ± 1.42 mm Hg in sessions 1-5, respectively, with no differences between treatment sessions 2, 4, and 5 (P = 0.105, Friedman). CONCLUSIONS: Tropicamide and atropine counteracted latanoprost's miotic effect, with atropine causing significantly larger mydriasis, sufficient for indirect ophthalmoscopy. Neither drug counteracted the hypotensive effect of latanoprost during this study period. Further studies are necessary to evaluate the potential risks in glaucomatous dogs.

Abdominal X-ray in Pediatric Acute Severe Colitis and Radiographic Predictors of Response to Intravenous Steroids.

BACKGROUND: Abdominal x-ray (AXR) can identify complications in acute severe colitis (ASC) and may assist in selecting high-risk children for early aggressive treatment. We aimed to describe AXR findings in pediatric ASC and to explore radiological predictors of response to intravenous corticosteroid (IVCS) therapy. METHODS: A total of 56 children with ASC were included in a multicenter, retrospective 1-year cohort study (41% boys, mean age 12.1 ±â€Š4.2). Radiographs of responders to IVCS and those requiring second-line salvage therapy by discharge were analyzed independently by 2 blinded radiologists. RESULTS: A total of 33 responders to IVCS were compared with 23 nonresponders. The day-3 Pediatric Ulcerative Colitis Activity Index (PUCAI) score was significantly higher in nonresponders (63 ±â€Š16 vs 46 ±â€Š21, P = 0.001). The mean transverse colon luminal diameter was 30 ±â€Š16 mm in responders and 38 ±â€Š16 mm in nonresponders (P = 0.94). The upper range of transverse colonic diameter in children <12 years was ∼40 mm, whereas in older children it was 60 mm as accepted in adults. Ulcerations and megacolon seen on AXR were associated with nonresponse to IVCS (P = 0.006 and 0.064, respectively). CONCLUSIONS: The presence of mucosal ulcerations and megacolon on AXR could be considered in the risk stratification of children with ASC for early aggressive treatment, together with the previously known day-3 and day-5 Pediatric Ulcerative Colitis Activity Index scores, albumin, and C-reactive protein.

Spirocercosis in dogs in Israel: A retrospective case-control study (2004-2009).

This case-control retrospective study (years 2004-2009) investigated the epidemiological, clinical, and diagnostic test findings of dogs with esophageal spirocercosis (ES) presented to the Hebrew University Veterinary Teaching Hospital (HUVTH) and coproscopy-positive dogs at the Kimron Veterinary Institute (KVI), Israel. It included 133 dogs with ES and 133 negative controls diagnosed at the hospital, and 343 dogs diagnosed at the KVI. The average incidence of ES at the HUVTH was 22.5/year, and the percentage of spirocercosis cases was stable at both institutions (HUVTH, 0.67-1.23%; KVI, 5-8%). Dogs aged > 5 years old had 100-fold likelihood to be infected compared to dogs aged ≤ 1 year of age (P < 0.001). Mean body weight (P = 0.0004), proportion of Retrievers (P = 0.002) and sporting breed dogs (P = 0.006) were higher, while proportion of toy breeds (P = 0.004) was lower in the ES group compared to the control group. The proportion of cases from Greater Tel-Aviv decreased (P = 0.002), while that of those from Judea and Jerusalem increased (P = 0.01) compared to the 1990 s. Spirocercosis occurred in 22 dogs despite past prophylactic avermectin treatment. Vomiting and regurgitation were the most common clinical signs of ES. Coproscopy was S. lupi-positive in 33/60 dogs (55.0%). The median number of esophageal nodules was two (range 1-8), with a median diameter of 3.5 cm (range 1.0-11.0). Malignant esophageal lesion transformation was confirmed in 29 dogs (22%). Despite preventive attempts, spirocercosis has spread in Israel over time, compared to previous findings, raising questions about the efficacy of the currently accepted prophylactic protocol is incompletely effective.

Visual estimation of pro-supination angle is superior to wrist or elbow angles.

OBJECTIVE: To examine our hypothesis that the accuracy of visual estimation, while measuring the angles of forearm, wrist and elbow, may vary between the different angles, and that this may depend on the experience of the observer. METHODS: A slide show comprising of clinical photos and radiographs of different elbow, forearm and wrist angles was presented to 164 attending orthopedic surgeons, orthopedic residents and medical students who made a visual estimation of the different joints' angles. RESULTS: Forearm pronation was found to be estimated most accurately (mean 6.1°) while radiographs of wrist flexion (mean 12°) and photos of wrist extension (mean 16°) were estimated the least accurately. Specialists estimated angles more accurately than residents and both were more accurate than students, regardless of the estimated joint. CONCLUSIONS: The accuracy of visual estimation of a joint's angle depends on the specific joint viewed. Experience in the practice of orthopedic surgery (and not only upper extremity surgery) will improve the accuracy of estimation in general. Regarding the elbow, forearm and wrist, the results of our study suggest that a goniometer should be used whenever an accuracy of up to 10° is important, and for measuring wrist flexion and extension.

Early endoscopic, laboratory and clinical predictors of poor disease course in paediatric ulcerative colitis.

OBJECTIVE: Data to support treatment algorithms in ambulatory paediatric UC are scarce. We aimed to explore the 1 year outcome in an inception cohort of paediatric UC patients and to identify early predictors of good outcome that might serve as short term treatment targets. DESIGN: A chart review of 115 children with new onset UC was performed (age 11 ± 4.1 years; 58 (50%) males; 86 (75%) extensive colitis; 70 (61%) moderate-severe disease; 63 (55%) received steroids at baseline). We assessed the Paediatric Ulcerative Colitis Activity Index (PUCAI) and laboratory variables at the time of diagnosis and at 3 months, and endoscopy at diagnosis. RESULTS: The 3 month PUCAI was the strongest predictor of 1 year sustained steroid free remission (SSFR) (area under the receiver operating characteristic curve (AUROC)=0.7 (95% CI 0.6 to 0.8) and colectomy by 2 years (AUROC=0.75 (0.6 to 0.89)). SSFR was achieved in 9/54 (17%) children who had active disease (PUCAI ≥ 10) at 3 months (negative predictive value (NPV)=83%) and by 4/46 (8.6%) of those with a PUCAI score >10; (NPV=91%, positive predictive value=52%; p<0.001), implying that PUCAI >10 at 3 months has a probability of 9% for achieving SSFR versus 48% with a PUCAI value of ≤10. None of the variables at baseline was predictive of SSFR or colectomy (endoscopic severity, disease extent, age, PUCAI or C reactive protein/erythrocyte sedimentation rate/albumin/haemoglobin; all AUROC<0.6, p>0.05) but baseline PUCAI predicted subsequent acute severe colitis and the need for salvage medical therapy. CONCLUSIONS: Completeness of the early response appears more important than baseline UC severity for predicting outcome in children, and supports using PUCAI<10 as a feasible treatment goal. Our data suggest that treatment escalation should be considered with a PUCAI value of ≥ 10 at 3 months.

Looking beyond discharge: clinical variables at trauma admission predict long term survival in the older severely injured patient.

BACKGROUND: Long term follow up is difficult to obtain in most trauma settings, these data are essential for assessing outcomes in the older (≥60) patient. We hypothesized that clinical data obtained during initial hospital stay could accurately predict long term survival. STUDY DESIGN: Using our trauma registry and hospital database, we reviewed all trauma admissions (age ≥60, ISS > 15) to our Level 1 center over the most recent 7 years. Mechanism of injury, co-morbidities, ICU admission, and ultimate disposition were assessed for 2-7 years post-discharge. Primary outcome was defined as long term survival to the end of the last year of the study. RESULTS: Of 342 patients discharged following initial admission, mean age was 76.2 ± 9.7, and ISS was 21.5 ± 6.9. 119 patients (34.8%) died (mean follow up 18.8 months; range 1.1-66.2 months). For 233 survivors, mean follow-up was 50.2 months (range 24.8-83.8 months). Univariate analysis disclosed post-discharge mortality was associated with age (80.1 ± 9.64 vs. 74.2 ± 9.07), mean number of co-morbidities (1.6 ± 1.1 vs. 1.0 ± 1.2), fall as a mechanism, lower GCS upon arrival (11.85 ± 4.21 vs. 13.73 ± 2.89), intubation at the scene and discharge to an assisted living facility (p < 0.001 for all). Cox regression analysis hazard ratio showed that independent predictors of mortality on long term follow-up included: older age, fall as mechanism, lower GCS at admission and discharge to assisted living facility (all = p < 0.0001). CONCLUSIONS: Nearly two-thirds of patients ≥60 who were severely injured survived >4 years following discharge; furthermore, admission data, including younger age, injury mechanism other than falls, higher GCS and home discharge predicted a favorable long term outcome. These findings suggest that common clinical data at initial admission can predict long term survival in the older trauma patient.
