Role of orthoptics and scoring system for orbital floor blowout fracture: surgical or conservative treatment

AIM: To assess the role of orthoptics in referring patients with orbital floor blowout fracture (OFBF) for conservative or surgical treatment and based on the results, to propose a scoring system for such decision making. METHODS: A retrospective analysis of 69 patients with OFBF was performed (35 treated conservatively, 34 surgically). The role of orthoptics in referring to surgery or conservative treatment was retrospectively evaluated, the factors with the highest significance for decision making were identified, and a scoring system proposed using Logistic regression. RESULTS: According to defined criteria, the treatment was unsuccessful in 2 (6%) surgically treated and only in one (3%) conservatively treated patient. The proposed scoring system includes the defect size and several values resulting from the orthoptic examination, the elevation of the eyebulb measured on Lancaster screen being the most significant. CONCLUSION: The study demonstrates the benefits of orthoptic examination when making decisions on conservative or surgical treatment and for diagnosing ocular motility disorder (with or without binocular diplopia) in OFBF patients. The proposed scoring system could, following verification in a prospective study, become a valuable adjunctive tool.     

Three-tesla MRI biphasic angiography: a method for preoperative assessment of the vascular supply in renal tumours—a surgical perspective

Purpose

The new generation of 3TMRI has improved spatial and time resolutions, which are favourable in imaging of the renal vasculature. In this study, we have compared the imaging findings of the renal blood vessels using 3TMRI and CT with intraoperative assessment of the renal vasculature as gold standard.

Methods

This prospective study was approved by the local ethical committee. Between 4/2011 and 12/2011, 80 patients with renal tumours underwent 3TMRA (angiography) (Magnetom SKYRA 3T, Siemens). Twenty of the patients were also examined with CT AG. The results of the CTA- and MRA-imaging studies were correlated with the intraoperative assessment of the renal vessels.

Results

Seventy patients (87.5 %) had a detailed intraoperative assessment of the renal vessels. The sensitivities for CTA and MRA were 88.2 and 88.6 %, respectively. All discrepancies between imaging studies and intraoperative findings were due to inability to identify small polar vessels. The results of MRA were concordant with CTA in 85.0 % of cases. The (three) discrepancies between MRI and CT were due to failure of MRI in identifying small polar vessels.

Conclusions

(1) 3TMRA gives detailed information about the renal vasculature including its topographical anatomy. (2) With MRI, small aberrant vessels are more frequently missed than with CTA. (3) CTA remains the gold standard. However, MRA may be used for planning of laparoscopic operations. (4) The quality of the 3D reconstruction is highly depending on the skills of the radiologist.     

Minimal residual disease detectable by quantitative assessment of WT1 gene before allogeneic stem cell transplantation in patients in first remission of acute myeloid leukemia has an impact on their future prognosis

Overall 42 patients (pts) transplanted in hematological CR1 were retrospectively analyzed. Median follow‐up was 15 months (range 2–77). The expression of WT1 gene was measured according to the European Leukaemia Net recommendations. At the time of allogeneic stem cell transplantation (allo‐SCT) 29 pts were WT1‐negative and 13 pts were WT1‐positive. In the univariate analysis, significantly better results were observed in the group of WT1 neg in terms of progression‐free survival (in three yr 77% vs. 27%, p = 0.001). In multivariate analysis, the only significant feature in terms of better OS was WT1 negativity (p = 0.029). Our results show that minimal residual disease status measured by quantitative assessment of WT1 gene in acute myeloid leukemia pts in CR1 significantly affects their future prognosis after allo‐SCT.     

Morbidity of Focal Therapy in the Treatment of Localized Prostate Cancer

Background

Focal therapy (FT) for prostate cancer (PCa) seems to be part of a natural evolution in the quest to improve the management of early organ-confined disease.

Objective

To assess the morbidity of the initial experience of FT in a tertiary referral center for PCa management.

Design, setting, and participants

From 2009 to 2011, a total of 1213 patients with clinically localized PCa were treated at our institution. Of these patients, 547 were considered to have indolent disease according to the D’Amico criteria for low-risk disease plus unilateral disease with a maximum of three positive biopsies. A total of 106 patients underwent FT using high-intensity focused ultrasonography (HIFU), brachytherapy, cryotherapy, or vascular-targeted photodynamic therapy (VTP).

Outcome measurements and statistical analysis

Complications were prospectively recorded and graded according to the Clavien-Dindo scale. Data were prospectively collected and retrospectively analyzed.

Results and limitations

This study included 106 patients, median age 66.5 yr (interquartile range [IQR]): 61–73), who had a prostate hemiablation; 50 patients (47%) had cryotherapy, 23 patients (22%) had VTP, 21 patients (20%) received HIFU, and 12 patients (11%) had brachytherapy. The median prostate-specific antigen (PSA) level was 6.1 ng/ml (IQR: 5–8.1), all the patients had a biopsy Gleason score of 6, and the median prostate weight was 43 g (IQR: 33–55). The median International Prostate Symptom Score was 6 (IQR: 3–10), and the median International Index of Erectile Function score was 20 (IQR: 15–23). After treatment, the median PSA at 3, 6, and 12 mo was 3.1 2.9, and 2.7 ng/ml (IQR: 2–5.1, 1.1–4.7, and 1–4.4), respectively. Thirteen percent of the patients experienced treatment-related complications. There were 11 minor medical complications (10 grade 1 complications and 1 grade 2 complication), 2 grade 3 complications, and no grade 4 or higher complications.

Conclusions

FT for a highly selected population with PCa is feasible and had an acceptable morbidity with <2% major complications.     

A case report of rapid spontaneous redistribution of acute supratentorial subdural hematoma to the entire spinal subdural space presenting as a Pourfour du Petit Syndrome and review of the literature

Objective

This report illustrates the rare rapid spontaneous redistribution of an acute intracranial supratentorial subdural hematoma (AISSDH) to the entire spinal subdural space (SSS). The study is also unique in that the spinal subdural hematoma (SSH) manifested by the extremely rare Pourfour du Petit Syndrome (PPS).

Methods

A 66-year-old man sustained blunt head trauma. On admission to the regional hospital, he scored 6 on GCS and his pupils were of equal size reacting to light. Initial computed tomography (CT) scan showed a unilateral AISSDH. The patient was referred to our department and arrived 16 h following the accident, at which time a repeat CT scan revealed almost complete resolution of the AISSDH without clinical improvement. On the 9th postinjury day transient anisocoria and tachycardia without spinal symptomatology developed. Since neither neurological examination nor follow-up CT scans showed intracranial pathology explaining the anisocoria, the patient was treated further conservatively. During the next 3 days circulatory instability developed and the patient succumbed to primary traumatic injury. Autopsy revealed a SSH occupying the entire SSS.

Conclusion

This case calls attention to the unique combination of the displacement of an AISSDH to the SSS and the presentation of this clinical entity by the PPS.     

Current status of epilepsy health care for adult patients from Central and Eastern European Union Countries—A survey of members of the Central Europe Epilepsy Experts Working Group

PurposeThe aim of this survey was to review and compare the current approaches to epilepsy management in Central and Eastern EU (CEEU) countries.MethodThe questionnaire was sent to ten invited experts from Bulgaria, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia, and Slovenia. It focused on the treatment of adults.ResultsThe number of neurologists and epilepsy reference centers is highly variable in CEEU countries. None of the analyzed states has a formal specialization in epileptology. No universal state-approved criteria for reference centers exist in Czech Republic, Estonia, Hungary, Latvia, and Slovenia. Generally, the protocols for epilepsy treatment in CEEU countries, including drug-resistant epilepsy, are in accordance with international guidelines; however, most countries have their own national standards of care and some have local clinical guidelines. Also, the reimbursement systems for antiepileptic drugs in CEEU countries are highly variable. Seven countries have epilepsy surgery centers. The costs of epilepsy surgeries are fully reimbursed, procedures performed abroad may also be covered. The length of time spent on waiting lists for surgery following the completion of preoperative investigations varies from two weeks to three years. The fraction of patients who qualified and were operated on within 12 months ranges from 20% to 100%.ConclusionThe lack of unified procedures pertaining to the evaluation and therapy of epilepsy is reflected by marked differences in access to treatment modalities for patients from CEEU countries.

Histopathology Image Analysis in Two Long‐Term Animal Experiments with Helical Flow Total Artificial Heart

Histopathological analysis can provide important information in long‐term experiments with total artificial heart (TAH). Recently, a new type of blood pump, the helical flow total artificial heart (HF‐TAH) was developed. This study aimed to investigate the changes in selected vital organs in animal experiments with implanted HF‐TAH. Samples from lung, liver, and kidneys from two female goats (No. 1301 and No. 1304) with implanted HF‐TAH were analyzed. Tissue samples were fixed in 10% formaldehyde and 4 µm thick transverse sections were stained with hematoxylin‐eosin (HE). Additional staining was done for detection of connective tissue (Masson‐Goldner stain) and for detection of iron (hemosiderin) deposits (Perls stain). Sections were scanned at 100× and 500× magnification with a light microscope. Experiment no. 1301 survived 100 days (cause of termination was heavy damage of the right pump); experimental goat no.1304 survived 68 days and was sacrificed due to severe right hydrodynamic bearing malfunction. Histopathological analysis of liver samples proved signs of chronic venostasis with limited focal necrotic zones. Dilated tubules, proteinaceous material in tubular lumen, and hemosiderin deposits were detected in kidney samples. Contamination of the organs by embolized micro‐particles was suspected at the autopsy after discovery of visible damage (scratches) of the pump impeller surface (made from titanium alloy) in both experiments. Sporadic deposits of foreign micro‐particles (presumably titanium) were observed in most of the analyzed parenchymal organs. However, the described deposits were not in direct connection with inflammatory reactions in the analyzed tissues. Histopathological analysis showed the presence of minimal contamination of the lung, kidney, and liver tissue samples by foreign material (titanium very likely). The analysis showed only limited pathological changes, especially in liver and kidneys, which might be attributed to the influence of artificial perfusion often observed in chronic TAH experiments.
