Managing in uncertain times

Radical change, often referred to as a paradigm shift, will occur in the wake of the United States healthcare reform effort currently underway. It will be value-based, community-oriented and patient- and family-centered. These changes will pose great challenges for materiel management. The future will call for integrated healthcare delivery networks that will see hospitals lose their preeminence as providers and, subsequently, needed revenues. Strategies such as implementation of total quality management, and vendor and community partnering will become more pronounced. Materiel managers will see their role change to one of information gathering and disseminating. All healthcare managers will need new skills to help shape the future of healthcare delivery, including the ability to challenge assumptions, understand that there are alternative realities, anticipate business trends, and create and implement a vision of the future of their organization.     

Variable CSF findings in early and late Lyme neuroborreliosis: A follow-up study in 47 patients

The cerebrospinal fluid (CSF) of 37 patients with early Lyme neuroborreliosis (ELN) and of 10 patients with late Lyme neuroborreliosis (LLN, duration of symptoms 7 months) was investigated for typical features differentiating between acute and chronic courses of disease. Individual patients were studied after 2 and 4 weeks, and 3, 6, and 12 months. Patients with ELN presented predominantly with symptoms of the peripheral nervous system, while patients with LLN generally suffered from symtoms of the central nervous system. At the first lumbar puncture, patients with ELN revealed a more intense pleocytosis in the CSF (P < 0.02) and a higher intrathecal synthesis of total IgM (P < 0.0003) and ofBorrelia burgdorferi-specific IgM antibodies (P < 0.01). At the same time, in patients with LLN, the blood-CSF barrier was more severely impaired (P = 0.03), and local production of total IgG (P = 0.0001), ofB. burgdorferi-specific IgG antibodies (P = 0.03) and of total IgA (P = 0.001) was more markedly increased. The quantity of intrathecally producedB. burgdorferi-specific IgA antibodies did not differ between the two study groups. Clinical recovery was usually accompanied by a considerable improvement of the blood-CSF barrier function and pleocytosis. After 6 months, the intrathecal synthesis of total IgG had significantly decreased in patients with ELN but not in those with LLN. At the same time, the CSF of most patients in both study groups still contained intrathecally producedB. burgdorferi-specific IgG antibodies. In the absence of clinical illness or symptoms of inflammation 6 and 12 months after treatment,B. burgdorferi-specific IgG antibodies in the CSF might simply indicate an anamnestic reaction to a previous infection of the central nervous system. Six months after antibiotic treatment, patients with ELN still revealed evidence of intrathecal synthesis of total IgM, whereas those with LLN did not. These antibodies, however, were not related toB. burgdorferi.     

Risk factors for mental disorder hospitalization after the Persian Gulf War: U.S. Armed Forces, June 1, 1991-September 30, 1993

Effects of Persian Gulf War (August 2, 1990–July 31, 1991) and Gulf War occupation on post-War hospitalization risk were evaluated through Cox proportional hazards modeling. Active-duty men (n = 1,775,236) and women (n = 209,760) in the Army, Air Force, Navy, and Marine Corps had 30,539 initial postwar hospitalizations for mental disorders between June 1, 1991 and September 30, 1993. Principal diagnoses in the Defense Manpower Data Center hospitalization database were grouped into 10 categories of ICD-9-CM codes. Gulf War service was associated with significantly greater risk for acute reactions to stress and lower risk for personality disorders and adjustment reactions among men. Personnel who served in ground war support occupations (men and women) were at greater risk for postwar drug-related disorders. Men who served in ground war combat occupations were at higher risk for alcohol-related disorders. Longitudinal studies of health, hospitalization, and exposure beginning at recruitment, are needed to better understand how exposure to combat affects the mental health of military personnel.     

Neurothekeoma palpebrae: a rare nerve sheath tumor arising in the eyelid

PURPOSE: To report a case of an eyelid neurothekeoma, a rare peripheral nerve sheath tumor. METHODS: Case report. RESULTS: An excisional biopsy, performed on a lesion removed from the upper eyelid of a 76-year-old woman, revealed the clinical and histopathologic features of a neurothekeoma, a tumor consisting of multiple collections of spindle cells in a myxomatous background. Immunohistochemical characterization showed positivity for NK1/C3, neuron-specific enolase, and alcian blue. CONCLUSION: Neurothekeoma palpebrae should be considered in the differential diagnosis of solitary nodules of the eyelids.
