 Background: The recent occurrence of a spontaneous intracerebral hemorrhage in Israel’s Prime Minister placed the scrutiny of local and international media on neurosurgeons as they made therapeutic decisions. In the ensuing public debate, it was suggested that extraordinary measures (surgical treatment) were undertaken only because of the celebrity of the patient.

Objectives: To evaluate the criteria used to select surgical versus medical management for SICH.

Methods: We retrospectively reviewed the files of 149 consecutive patients admitted with SICH[1] from January 2004 through January 2006 to our medical center. Their mean age was 66 (range 3–92 years), and 62% were male. SICH localization was lobar in 50% of patients, thalamus in 23%, basal ganglia in 15%, cerebellum in 13%, intraventricular in 6%, and pontine in 1%. Mean admission Glasgow Coma Score was 9 (range 3–15). Risk factors included hypertension in (74%), diabetes mellitus (34%), smoking (14%) and amyloid angiopathy (4%). Fifty percent of patients were on anticoagulant/antiplatelet therapy, including enoxaparin (3%), warfarin (7%), warfarin and aspirin (9%), or aspirin alone (34%).      

Results: Craniotomy was performed in 30% of patients, and ventriculostomy alone in 3%. Rebleed occurred in 9% of patients. Six months after the treatment 36% of operated patients were independent, 42% dependent, and 13% had died. At 6 months, 37% of non-operated patients were independent, 15% dependent, and 47% had died.

Conclusions: One-third of the SICH patients, notably those who were experiencing ongoing neurologic deterioration and had accessible hemorrhage, underwent craniotomy. The results are good, considering the inherent mortality and morbidity of SICH.

 Moyamoya disease is a cerebral vasculopathy characterized mainly by progressive narrowing of the major intracranial vessels. While more common and having a familial predilection in the Far East, it can also develop in association with some common hereditary diseases and can be acquired after environmental exposure. In the young its manifestations are the result of cerebral ischemia. Adults usually suffer from repeated incidents of intracerebral hemorrhage. Surgical revascularization of ischemic cerebral territories plays a major role in their treatment. We review the literature and present our series of three adult and five pediatric patients; these patients were diagnosed at our institution and treated with indirect revascularization techniques.

 Bleeding during retropubic radical prostatectomy arises from venous structures in the majority of cases. Since its introduction two decades ago, the nerve-sparing procedure with surgical control of the dorsal venous complex has led to a reduction in blood loss and blood transfusion rate. The reduction in blood loss is a result of better understanding of the prostatic blood vessel anatomy, extensive surgical experience over time, and reduction in transfusion triggers with an acceptance of lower postoperative hemoglobin values. Increased blood loss during RRP[1] is associated with poorer outcomes most probably due to surgical difficulties. But as for now, there are no decisive risk factors for clinically significant bleeding during RRP although newer technologies for hemostasis of the dorsal vein complex are being utilized.

Background: Eyes scheduled for posterior segment surgery may have cataract, which obscures the visualization of the retina. Surgery may be carried out either by a two-step procedure: i.e., removal of the cataract followed later by posterior segment surgery; or it may be done in a single session: i.e., combined surgery of both the anterior and posterior segments.

Objective: To evaluate the outcomes of combined surgery by phacoemulsification and vitrectomy.

Methods: We retrospectively reviewed the records of 42 patients with coexisting cataract and vitreoretinal disease who underwent combined surgery by phacoemulsification and pars plana vitrectomy at one session.

Results: Indications for surgery were vitreous hemorrhage in 71.4%, retinal detachment in 11.9%, macular hole in 11.9%, and epiretinal membrane in 4.8%. There were no significant intraoperative complications.The main early postsurgical complications were fibrinous formation in 11.9%, elevated intraocular pressure in 23.8%, and recurrent vitreous hemorrhage in 9.5%. There were a few late complications related to phacoemulsification: posterior synechia in 9.5%, posterior capsular opacification in 7.1%, and dislocating intraocular lens in 4.8%. Recurrent retinal detachment occurred in five eyes and rubeoisis iridis in one. Visual acuity was improved in 85.8%, stable in 7.1% and worse in 7.1%.

Conclusions: Phacoemulsification performed at the time of posterior segment surgery enables good visualization during the vitrectomy, facilitates surgery, and is associated with only minor complications. In cases with cataract and vitreoretinal diseases, combined surgery by phacoemulsification and vitrectomy in one session may be considered.

Background: Increased serum potassium and intraventricular hemorrhage occur frequently in preterm infants.

Objective: To retrospectively analyze data obtained on infants with severe IVH[1] in relation to blood K+ concentrations.

Methods: We identified all patients with severe IVH born between July 1997 and July 2000. Each patient was pair-matched with a control infant of the same gestational age (±1 week) without IVH in terms of head ultrasound findings on day 5, and whole blood K+ on days 3–5.

Results: There were 24 infants in each group. The IVH group had significantly lower 1 minute Apgar scores and pH and higher blood K+ than the control group. Blood pH and K+ were inversely correlated. Stepwise regression analysis, taking into account blood pH and 1 minute Apgar score, showed a correlation only between blood K+ and IVH status.

Conclusions: Severe IVH is significantly associated with higher blood K+ concentrations. A causal relationship cannot be ascertained at this point.

Background: The prevalence of traumatic hyphema as well as the distribution of its severity varies between different patient populations. Treatment recommendations in the literature differ significantly among various published reports. This lack of a uniformly accepted treatment probably reflects the different characteristics of this pathology among the populations investigated and calls for a population-adjusted treatment recommendation.

Objectives: To report the characteristics and functional outcome of patients with traumatic hyphema and to discuss possible recommendations regarding the use of ε‑aminocaproic acid.

Methods: A prospective, non-randomized study was conducted among 154 consecutive patients with traumatic hyphema, including data collection of ophthalmic status at various time points, the presence or absence of secondary hemorrhage, and final visual acuity.

Results: Of the 154 eyes studied over 3½ years, nearly 90% had hyphema of grade 1 or less, 3 (3.25%) experienced rebleeding, and 2 (1.3%) – neither of which rebled – needed surgical intervention. None of the four patients who experienced final visual acuity of 6/40 or less suffered rebleeding.

Conclusion: The use of ε‑aminocaproic acid in the studied population was unjustified and routine use of e-aminocaproic acid in our patient population is probably not indicated. A treatment policy regarding e-aminocaproic acid use should be adjusted to the population being treated.
