Lepirudin as a safe alternative for effective anticoagulation in patients with known heparin-induced thrombocytopenia undergoing percutaneous coronary intervention: case reports.

Heparin-induced thrombocytopenia (HIT) is a well-documented complication of heparin anticoagulation therapy. Heparin's frequent use in the cardiovascular population poses a significant challenge for managing patients with HIT in need of percutaneous coronary intervention (PCI). We describe four patients with HIT who successfully underwent PCI without thrombotic or hemorrhagic complications while on lepirudin.     

Serum-sickness-like illness as a complication after streptokinase therapy for acute myocardial infarction

We report a case of serum-sickness-like illness in a 47-year-old patient who received early high-dose intravenous and intracoronary streptokinase following acute myocardial infarction. The picture comprised severe arthralgias, fever, an urticarial rash and marked elevation of circulating immune complexes. This case represents a rare complication of streptokinase therapy.     

When cure is no option: How explicit and hopeful can information be given? A qualitative study in breast cancer

Objective

To investigate how oncologists can balance explicit with general and realistic with hopeful information when discussing various topics at the transition from curative to palliative care in breast cancer.

Methods

Qualitative analysis of focus groups consisting of female breast cancer survivors and healthy women.

Results

Perceptions of survivors and healthy women largely overlapped. Participants thought that oncologists can help patients regain a future perspective during this consultation. To achieve this, four themes seemed important: honest medical information, availability of continued support, hope has many faces, and space to choose. Moreover, participants stressed they would need time to let the message sink in before any further information was provided.

Conclusion

Participants thought that when confronted with this type of consultation they would need – more or less explicit – medical information and information regarding support. In order to maintain hope, knowledge about (treatment) possibilities is important, but also the certainty not to be abandoned by the hospital at a later stage of the disease and the confidence to remain able to make one's own decisions.

Practice implications

A life-limiting diagnosis may shatter patients’ future perspective; however, this study provides suggestions for oncologists to create a new perspective.     

Pin tract infection of operatively treated supracondylar fractures in children: long-term functional outcomes and anatomical study

Purpose

The purpose of our study was to determine the long-term functional outcomes of pin tract infection after percutaneous pinning of displaced supracondylar humeral fractures in children, and to evaluate the potential for intracapsular pin placement based on pin configuration in cadaveric elbows.

Methods

We conducted a retrospective review of all patients requiring percutaneous pinning in a single institution over a 19-year period. The functional outcome assessment consisted of a telephone interview using the Disabilities of the Arm, Shoulder and Hand (DASH)] Outcome Measure and the Patient-Rated Elbow Evaluation (PREE) questionnaires. The risk of intracapsular pin placement was studied in cadaveric elbows for the three most common pin configurations: divergent lateral, parallel lateral, and medial and lateral crossed pins.

Results

Of 490 children, 21 (4.3 %) developed pin tract infection. There were 15 (3.1 %) superficial and six (1.2 %) deep infections (osteomyelitis and septic arthritis). Both DASH and PREE scores were excellent at a mean of 18 years post-surgery. The risk of intracapsular pin placement using parallel lateral pins was found to be greater (p < 0.05) than either crossed or divergent lateral pinning configurations.

Conclusions

Most infections after pinning of supracondylar humerus fractures are superficial and can be managed with pin removal, oral antibiotics, and local wound care. Septic arthritis and osteomyelitis are rare complications; when they do occur, they seem to be associated with parallel lateral pin configuration, though a causal relationship could not be established from the current study. Satisfactory long-term outcomes of these deep infections can be expected when treated aggressively with surgical debridement and intravenous antibiotics.     

Targeted deletion of Vglut2 expression in the embryonal telencephalon promotes an anxiolytic phenotype of the adult mouse

Background

Anxiety is a natural emotion experienced by all individuals. However, when anxiety becomes excessive, it contributes to the substantial group of anxiety disorders that affect one in three people and thus are among the most common psychiatric disorders. Anxiolysis, the reduction of anxiety, is mediated via several large groups of therapeutical compounds, but the relief is often only temporary, and increased knowledge of the neurobiology underlying anxiety is needed in order to improve future therapies.

Aim

We previously demonstrated that mice lacking forebrain expression of the Vesicular glutamate transporter 2 (Vglut2) from adolescence showed a strong anxiolytic behaviour as adults. In the current study, we wished to analyse if removal of Vglut2 expression already from mid-gestation of the mouse embryo would give rise to similar anxiolysis in the adult mouse.

Methods

We produced transgenic mice lacking Vglut2 from mid-gestation and analysed their affective behaviour, including anxiety, when they had reached adulthood.

Results

The transgenic mice lacking Vglut2 expression from mid-gestation showed certain signs of anxiolytic behaviour, but this phenotype was not as prominent as when Vglut2 was removed during adolescence.

Conclusion

Our results suggest that both embryonal and adolescent forebrain expression of Vglut2 normally contributes to balancing the level of anxiety. As the neurobiological basis for anxiety is similar across species, our results in mice may help improve the current understanding of the neurocircuitry of anxiety, and hence anxiolysis, also in humans.
