Alcohol consumption during pregnancy and lactation periods may result to some physical and histopathological changes in offsprings. This study was undertaken to investigate the possible effects of maternal alcohol intake on the testes and accessory sex organs of male pups of albino rats. Three groups of female albino rats; A, B and C were used for this study. Group A was the control group while groups B & C served as test groups. Eight male pups were randomly selected weekly (for five weeks) from each group and were sacrificed. The individual weights of the testes and accessory sex organs were determined and thereafter fixed in formol saline. Histopathological investigation was done and photomicrographs were taken. There was a significant reduction (P<0.05) in the mean weights of the testes in the test groups compared with control in all weeks under study. In contrast a significant reduction (P<0.05) in the mean values of the weights of ventral lobes of prostate and epididymis were only noticed in weeks 5 and 6 while the mean value of weights of the vas deferens showed significant reduction (P<0.05) in week 5 of the test groups compared with control group. The histopathological results revealed that exposure to alcohol caused focal coagulative necrosis of testicular seminiferous tubules in pre-natal alcohol exposed group B and a more diffuse coagulative necrosis of testicular seminiferous tubules in pre-and post- natal alcohol exposed group C. Therefore, there is the need for controlled alcohol consumption during pregnancy and lactation periods.

Authors: Gu Yang , Duan Ruowang , Song Jiong , Lv Xin 
Published: January 2019

Abstract
Background: Lung resection after previous contralateral pneumonectomy is rare. We present a case of right anterior segmentectomy despite previous left pneumonectomy, demanding special airway management strategy.
Case presentation: A 48-year-old woman was going to have the right anterior segmentectomy through uniportal video-assisted thoracoscopy (VATS) who had left pneumonectomy two years ago. A 32-French left-sided double-lumen endobronchial tube (DLT) was chosen and adapted. The DLT was intubated into the bronchus intermedius. And the upper lobe can be isolated from the ventilation in the middle and lower lobes when the bronchial cuff’s inflated. The perioperative period was uneventful and the pathological diagnosis was adenocarcinoma.
Conclusion: Lung cancer radical resection was discouraged after previous contralateral pneumonectomy partly due to the challenging ventilation and isolation. With this new DLT adapting and intubation technique showed in this case, the challenging ventilation and isolation that deter the promotion of the operation could be solved.

Abstract
Background: There is no specific guidelines concerning intraoperative management of brain-dead donors (BDD) during organ procurement (OP). This study aimed at describing usual anesthetic practices for BDD during an OP procedure and to assess the knowledge and self-confidence of French anesthesiologists with this practice.
Methods: An electronic, national and anonymous survey with closed-questions about anesthetic management of BDD was distributed to French anesthesiologists via the mailing list of the French Society of Anesthesiology and Intensive Care. The questionnaire included questions concerning monitoring, intraoperative resuscitation, anesthetic drugs use and confidence of the respondents.
Results: 458 responses were analyzed. Respondents were mainly attending physicians with more than 10 years of professional experience, equally distributed between university and non-university centers. Seventy-eight percent of them declared knowledge about guidelines regarding ICU management of BDD. Advanced hemodynamic monitoring and endocrine substitution were poorly considered by respondents (31% and 35% of respondents, respectively). 98% of the respondents used crystalloids for fluid resuscitation. During the procedure, use of neuromuscular blockers, opioids and sedative agents were considered by respectively 84%, 61% and 27% of the respondents. A very high level of agreement (10 [8-10], on a ten-points Likert-style scale) was reported concerning the expected impact of intraoperative anesthetic management on the primary function of grafts.
Conclusions: Declared anesthetic practice appeared in accordance with guidelines concerning ICU management of organ donors. Further studies are needed to evaluate the specific impact of intraoperative management during this procedure and thus the need for specific anesthetic guidelines.

Published: January 2019

Abstract
Background: To report a case of a cerebral Arteriovenous Malformation(AVM) with eye symptoms firstly and review the characteristic of this case and the main confusing point for diagnosis of such case.
Case presentation: A 58-year-old women presented to the ophthalmology clinic with 1 and an half year of right eye redness, Ocular hypertension and recurrent headache. One and a half year ago she was diagnosed as right eye dry eye and glaucoma and had received treatment according to diagnosis, however all the treatment did not lead to any improvement of redness and headache. On physical examination, it revealed dry eye and severe corkscrew hyperemia with dilated vessels in the right eye. After we consider that the symptom may be related to intracranial abnormal vessels, Computed tomography angiography and venography (CTA+CTV) were performed and the results showed an arteriovenous malformation (AVM) of right parietal-occipital area in the brain. The AVM was definitely located by the further examination of Digital subtraction angiography (DSA). After the AVM endovascular embolism treatment, the conjunctival congestion of the right eye was significantly relieved and the intraocular pressure was decreased to normal.
Conclusion: In clinical practice, when found corkscrew hyperemia accompanied by neurological symptoms, it might be considered as a result from cerebral vessels diseases, so in this case ophthalmologists diagnosis should combine disease history and imaging examination.

Risk Factors for and Management of Anterior Chamber Intravitreal Dexamethasone Implant Migration
Authors: Röck Daniel , Bartz-Schmidt Karl Ulrich , Röck Tobias 
Published: January 2019

Abstract
Background: This study aimed to investigate the incidence of and risk factors for the anterior chamber migration of an intravitreal dexamethasone implant (Ozurdex®).
Methods: A retrospective review of 640 consecutive intravitreal dexamethasone implant injections was conducted from February 2011 through February 2018 at the University Eye Hospital in Tübingen, Germany. Those patients who experienced anterior chamber dexamethasone implant migrations were identified, as well as the reasons for the anterior chamber migration. The surgical histories were obtained and comprehensive ophthalmic examinations were conducted for all of the eyes. Cross-tabulations, chi-squared tests, and Fisher's exact tests were used to assess the influences of different factors on the anterior chamber implant migrations.
Results: Overall, 4 eyes of four patients (0.63%) showed anterior chamber implant migrations. All four of the eyes were pseudophakic, and they had undergone prior vitrectomies. Three eyes had sclerally-fixated intraocular lenses, and one eye had a posterior chamber intraocular lens in the capsular bag, with a capsular tension ring due to partial zonular dehiscence. When comparing the vitrectomized eyes with reduced zonular/capsular bag complex integrity to the vitrectomized pseudophakic eyes with intact zonular/capsular bags, the former were significantly associated with an increased risk of anterior chamber implant migration (P = 0.008). The vitrectomized pseudophakic eyes, in contrast to the nonvitrectomized pseudophakic eyes, were significantly associated with an increased risk of anterior chamber implant migration (P = 0.009).
Conclusions: The anterior chamber migration of an intravitreal dexamethasone implant is a serious complication. To minimize the risk of permanent corneal edema, immediate removal of the implant is important. Those patients with insufficient zonular support, defects, or missing posterior capsular membranes and vitrectomy histories present a high risk of anterior chamber dexamethasone implant migration.
