BACKGROUND: Pulmonary hypertension (PH) associated with end stage liver disease is rare but the risk of hemodynamic deterioration during liver transplantation may be high. This study was done to characterize the pulmonary hemodynamics during liver transplantation and to seek the relationship between pulmonary artery pressure (PAP) and other hemodynamic variables. METHODS: One hundred patients undergoing liver transplantation were chosen and we divided patients into normal and PH groups (mean pulmonary artery pressure [MPAP] > 25 mmHg). Hemodynamic data was collected throughout the surgery. Studied variables between groups were analyzed with an unpaired t-test. The relationship between MPAP and other hemodynamic variables was analyzed with a linear regression test. Survival analysis was performed by cumulative survival analysis (Logrank test). RESULTS: Incidence of PH during liver transplantation was 34%, and true PH (pulmonary vascular resistance index [PVRI] > 150 dyne.sec/cm5/m2, MPAP > 25 mmHg) was 7%. MPAP, systemic vascular resistance index, cardiac index, right ventricular ejection fraction, maximum elastance, central venous pressure (CVP), pulmonary artery occlusion pressure (PAOP), and right ventricular end-diastolic volume index were significantly higher in the PH group. In the PH group, right ventricular function curve was abnormal. MPAP correlated significantly with PAOP, and CVP (P < 0.01). One year survival rate showed no significant difference between groups (Logrank test P = 0.49). CONCLUSIONS: Episodes of increased pulmonary artery pressure during liver transplantation was not infrequent. PAP was more dependent on preloads. In patients with high PAP, RV diastolic dysfunction was usually observed. Early mortality rate after liver transplantation was not associated with PH.

PURPOSE: To compare the changes in strabismus angle and deviation between two groups: a bilateral lateral rectus recession (Group 1) and a unilateral lateral rectus recession in exotropia (Group 2). METHODS: A retrospective survey was conducted on 198 patients who had received exotropia surgery in our ophthalmology clinic from September 2003 to April 2007. A total of 116 patients were in Group 1, and 82 patients were in Group 2. RESULTS: The average deviations of the first postoperative month and the first postoperative year were -1.96 D +/- 4.75, 2.5 D +/- 7.82 for Group 1 and 0.77 D +/- 2.87, 5.94 D +/- 3.38 for Group 2. Revealing statistical significance between the 2 Groups: Group 1 had 30 failure cases (25.9%) and their 1 postoperative year average deviation was 5.42 D +/- 13.97, while Group 2 showed 24 failure cases (29.3%) and their 1-postoperative-year average deviation was 13.0-79 +/- 3.04. Group 1 had less strabismus angle and a greater standard deviation than Group 2, as Group 1 had more overcorrection. Among the 30 failure cases of Group 1, 9 were overcorrected and 21 were undercorrected, but all 24 failure cases in Group 2 were undercorrected. CONCLUSIONS: The strabismus angle after lateral rectus recession showed a wider variation and a larger difference in bilateral lateral rectus recession than in the unilateral lateral rectus recession.

PURPOSE: Joubert syndrome presents neonatal respiratory abnormalities and other clinical manifestations. Pathologically the patients show hypoplasia or agenesis of cerebellar vermis and other intracranial anomalies. Our purpose is to evaluate the clinical manifestations and MR findings of Joubert syndrome. MATERIALS AND METHODS: Among the patients presenting with clinical stigmata of Joubert syndrome and agenesis of vermis on MR imaging, eight patients who did not satisfied the criteria of Dandy-Walker malformation, tectocerebellar dysraphia and rhombencephalosynapsis were selected. MR findings and clinical manifestation were analyzed. RESULTS: On MR imaging, agenesis of the cerebellar vermis (all cases), hypoplasia of the cerebellar peduncle (6cases), fourth ventricular contour deformity(6cases), tentorial elevation (4cases), deformity of the lateral ventricles (4cases), dysgenesis of the straight sinus (3cases) were demonstrated. Other findings were abnormalities of corpus callosum (3cases), falx anomalies (3 cases), occipital encephalomeningocele (2 cases) and fluid collection in posterior cranial fossa (2cases). Clinical manifestations were developmental delay (5cases), abnormal eyeball movement (3cases), hypotonia (2 cases), neonatal rerspiratoy abnormality (2cases), etc. CONCLUSION: Joubert syndrome showed various clinical manifestations and intracranial anomalies. MR imaging is an useful modality in detection of the cerebellar vermian agenesis and other anomalies of the patients.

Purpose: To report a case of subacute methicillin-resistant coagulase-negative Staphylococcus hominis endophthalmitis after re-operation for penetrating keratoplasty in a patient who had a penetrating keratoplasty rejection.Case summary: A 74-year-old man with underlying diabetes and hypertension who underwent bilateral penetrating keratoplasty at another hospital underwent penetrating keratoplasty reoperation due to corneal transplant rejection in the right eye. He had a history of end-stage glaucoma in the right eye and the visual acuity was finger counting at 30 cm. About 25 days postoperatively, the corneal epithelial defect was first found. Treatment based on suspicion of herpes simplex virus infection did not result in improvement and endophthalmitis was suspected in the right eye about 35 days after surgery. Anterior chamber irrigation, pars planar vitrectomy, and intravitreal antibiotic injection were performed. Culture revealed methicillin-resistant coagulase negative Staphylococcus hominis. After 2 months of treatment, the anterior chamber and vitreous inflammation decreased and best corrected visual acuity in the right eye recovered to 0.06. Conclusions Subacute endophthalmitis caused by methicillin-resistant coagulase-negative Staphylococcus may occur after penetrating keratoplasty. Transplant failure due to infection can be avoided with vitrectomy and antibiotic treatment at the right time.

Congenital pulmonary lymphangiectasia (CPL) is a rare lymphatic pulmonary abnormality. CPL with respiratory distress has a poor prognosis, and is frequently fatal in neonates. We report a case of pneumonectomy for CPL in a newborn. An infant girl, born at 39 weeks' after an uncomplicated pregnancy, exhibited respiratory distress 1 hr after birth, which necessitated intubation and aggressive ventilator care. Right pneumonectomy was performed after her symptoms worsened. Histologic examination indicated CPL. She is currently 12 months old and developing normally. Pneumonectomy can be considered for treating respiratory symptoms for improving chances of survival in cases with unilateral CPL.
