Osteochondral Fracture of the Fourth Metatarsal Head Treated by Open Reduction and Internal Fixation

Fracture of the metatarsal head is uncommon, and reports of isolated osteochondral fracture of the metatarsal head are rare. Because of the distal location of the fracture, it is difficult to achieve and maintain reduction, and potential complications include avascular necrosis and subchondral fatigue fracture. The authors present a case of an osteochondral fracture in a 40-year-old man, which was treated by open reduction and internal fixation with a single twist-off screw, with good results 12 months postoperatively.     

Preoperative Clinic Visits Reduce Operating Room Cancellations and Delays

Background: Anesthesiologist-directed preoperative medicine clinics are used to prepare patients for the administration of anesthesia and surgery. Studies have shown that such a clinic reduces preoperative testing and consults, but few studies have examined the impact of the clinic on the day of surgery. The authors tested whether a visit to an anesthesia preoperative medicine clinic (APMC) would reduce day-of-surgery case cancellations and/or case delays.

Methods: The authors conducted a retrospective chart review of all surgical cases during a 6-month period at the University of Chicago Hospitals. Case cancellations and rates of first-start case delay over the 6-month period were cross-referenced with a database of APMC attendees in both the general operating rooms and the same-day surgery suite. The impact of a clinic visit on case cancellation and delay in both sites were analyzed separately.

Results: A total of 6,524 eligible cases were included. In the same-day surgery suite, 98 of 1,164 (8.4%) APMC-evaluated patients were cancelled, as compared with 366 of 2,252 (16.2%) in the non-APMC group (P < 0.001). In the general operating rooms, 87 of 1,631 (5.3%) APMC-evaluated patients were cancelled, as compared with 192 of 1,477 (13.0%) patients without a clinic visit (P < 0.001). For both operating areas, APMC patients had a significantly earlier room entry time than patients not evaluated in the APMC.     

Differenzialdiagnose schlafbezogener Atmungsstörungen

Zusammenfassung Die Differenzialdiagnose schlafbezogener Atmungsstörungen (SBAS) erfolgt in Anlehnung an die durch die im Jahr 2005 von der American Academy of Sleep Medicine (AASM) neu aufgelegte Internationale Klassifikation von Schlafstörungen (ICSD-2). Die ICSD-2 teilt die derzeit bekannten Schlaf- und Aufwachstörungen in 8 Kategorien ein, die SBAS werden in Kategorie II aufgeführt. Die ICSD-2 ist kompatibel zu den international gebräuchlichen Systemen der Klassifikation von Krankheiten (ICD-9, ICD-10). Grundlage aller differenzialdiagnostischen Erwägungen stellt neben der ausführlichen Anamnese die Polysomnographie dar, ggf. ergänzt durch weiterführende internistische, neurologische, pädiatrische, Hals-Nasen-Ohren-ärztliche, Mund-Kiefer-Gesichts-chirurgische sowie neuropsychologische und neurophysiologische Untersuchungen.     

Models of Parkinson's disease.

Parkinson's disease (PD) is a heterogenous disease likely to be caused by more than one specific aetiological factor. In rare familial cases of PD with similar clinical features to the idiopathic form of the disease, the underlying genetic cause has been identified. These PD-associated genes have been manipulated to create animal and cell culture models of the disease that have helped to further our understanding of the pathogenesis of PD, particularly concerning causes of the selective loss of dopaminergic neurons at the molecular level. In addition, these models will aid the future development of rational therapeutic strategies. This study briefly reviews toxin-induced models and the genetics of PD. It focuses on recently developed animal models of PD, as well as in vitro approaches to model the disease.     

Cryotherapy in rectal cancer. A palliative local tumor treatment]

Cryotherapy was applied to 182 rectal cancer patients in the Department of General Surgery, University of Ulm, between 4/1982 and 4/1991. Recipients of this tumor freezing therapy were patients whose general condition was bad, patients with an advanced inoperable carcinoma, patients with tumor recurrence and patients refusing operation. Rectal carcinomas, mostly in an advanced stage, were usually freezed several times. Only 4 patients with general inoperability reached the survival time margin of 5 years. In 18 patients local tumor destruction was possible by application of cryotherapy. In 80% of cases disagreeable tumor symptoms like tenesma, mucous discharge and oozing hemorrhages could be reduced or completely removed. Perianal pain and intense tumor bleeding could be relieved temporarily or definitely in only 50% of patients. An artificial anus could be avoided in 80% of cases by local tumor destruction/reduction or arrest of tumor growth. The mean survival time of patients with tumor recidivation was 11 months after onset of the recurrence. Tumor progression, incontinence and iatrogenic rectal perforation made an artificial anus necessary in 14 patients.     

Managed Migration: The Caribbean Approach to Addressing Nursing Services Capacity

Objective. To (1) provide a contextual analysis of the Caribbean region with respect to forces shaping the current and emerging nursing workforce picture in the region; (2) discuss country-specific case(s) within the Caribbean; and (3) describe the Managed Migration Program as a potential framework for addressing regional and global nurse migration issues.
Principal Findings. The Caribbean is in the midst of a crisis of shortages of nurses with an average vacancy rate of 42 percent. Low pay, poor career prospects, and lack of education opportunities are among the reasons nurses resign. Many of these nurses look outside the region for job opportunities in the United Kingdom, Canada, the United States, and other countries. Compounding the situation is the lack of resources to train nurses to fill the vacancies. The Managed Migration Program of the Caribbean is a multilateral, cross-sector, multi-interventional, long-term strategy for developing and maintaining an adequate supply of nurses for the region.
Conclusions. The Managed Migration Program of the Caribbean has made progress in establishing regional support for addressing the nursing shortage crisis and developing a number of interesting initiatives such as training for export and temporary migration. Recommendations to move the Managed Migration Program of the Caribbean forward focus on advocacy, integration of the program into regional policy decisions, and integration of the program with regional health programming.
