Case ReportsCombined usage of inhaled and intravenous milrinone in pulmonary hypertension after heart valve surgery.
Secondary pulmonary hypertension is a frequent condition after heart valve surgery. It may significantly complicate the perioperative management and increase patients' morbidity and mortality. The treatment has not been yet completely defined principally because of lack of the selectivity of drugs for the pulmonary vasculature. ⋯ We obtained satisfactory reduction in mean pulmonary artery pressure in both patients, and they were successfully extubated and discharged. Although it is a very small sample of patients, we conclude that the combination of inhaled and intravenous milrinone could be an effective treatment of secondary pulmonary hypertension in high-risk cardiac valve surgery patient. The exact indications for inhaled milrinone usage, optimal concentrations for this route, and the beginning and duration of treatment are yet to be determined.

The proximal femoral nail antirotation (PFNA) in the treatment of proximal femoral fractures.
Proximal femoral fractures, especially in elderly persons with osteoporosis, present a challenge for the traumatologist. While the dynamic hip screw (DHS) became the implant of choice for the treatment of stable fractures, the ideal implant for the treatment of unstable fractures remains an issue. In our experience, Proximal Femoral Nail Antirotation (PFNA) is an excellent device for osteosynthesis as it can be easily inserted, it provides angular and rotational stability and allows early weight bearing on the affected limb. ⋯ The majority of patients regained their pre-injury mobility status. The PFNA is an excellent implant for stabilisation of both trochanteric and complex combination fractures as well as an exceptional device for reosteosynthesis. It is easily inserted with few intra- and postoperative complications and allows early weight bearing on the affected limb as well as quicker rehabilitation of patients.

Cardiopulmonary effects of hemorrhagic shock in splenic autotransplanted pigs: a new surgical model.
The spleen is an important organ for hemodynamic compensation during hemorrhagic shock. The aim of the study was to compare the hemodynamic and metabolic responses of sham-operated pigs with intact spleen, splenectomized pigs, and splenic autotransplanted pigs during hemorrhagic shock. Hemorrhagic shock was induced by 30% total blood volume bleed in sham-operated, splenectomized and splenic autotransplanted pigs (n = 20). ⋯ Hemoglobin and hematocrit were significantly lower in the splenectomized and splenic autotransplant groups as compared with the control group at 60 and 100 minutes after hemorrhage (p < 0.05). Unlike intact spleen, splenic autotransplant could not improve hemodynamic parameters in hemorrhagic shock in pigs. In comparison to mice, rats or dogs, this species could be an interesting investigation model to test new surgical procedures during splenic related hemorrhagic shock, with potential applications in human medicine.

Case ReportsTrauma related fat embolism syndrome in forensic practice.
The fat embolism syndrome (FES) in forensic practice is observed usually in cases of polytrauma related deaths. FES is rare, but serious complication after trauma. The most cases of post traumatic fat embolism are not fatal and it's very likely that many cases of mild fat embolism are overlooked. ⋯ We present one case of FES to emphasize the arising need of a quantitative analysis of both the size and localization of the fat emboli in order to grade the severity of FES and its relative contribution in pathophysiology of death. The postmortem diagnosis of fat embolism syndrome (FES), traditionally based on the histological demonstration of fat globules seems not to be enough, nowadays. A quantitative analysis of both the size and localization of the fat emboli has been discussed as reliable method of grading the pulmonary fat embolism in order to determine its relative functional contribution in death pathogenesis.

What associates Charles Bonnet syndrome with age-related macular degeneration?
Charles Bonnet syndrome (CBS) is a condition related to patients with visual loss due to age related macular degeneration or glaucoma that are having complex visual hallucinations. The CBS was first described by Swiss physician Charles Bonnet in 1760. Affected patients, who are otherwise mentally healthy people with significant visual loss, have vivid, complex recurrent visual hallucinations (VHs). ⋯ Cognitive defects, social isolation, and sensory deprivation have also been implicated in the etiology of this condition. This study was conducted on 350 patients diagnosed with Age-Related Macular Degeneration (AMD) and shows incidence of CBS in 13% of patients with AMD. Furthermore, we have found higher incidence of CBS in patients with massive loss of vision in peripheral visual field which is not age related.
