Critical assessment of statewide hospital pharmaceutical surge capabilities for chemical, biological, radiological, nuclear, and explosive incidents

INTRODUCTION: In recent years, government and hospital disaster planners have recognized the increasing importance of pharmaceutical preparedness for chemical, biological, radiological, nuclear, and explosive (CBRNE) events, as well as other public health emergencies. The development of pharmaceutical surge capacity for immediate use before support from the (US) Strategic National Stockpile (SNS) becomes available is integral to strengthening the preparedness of local healthcare networks. METHODS: The Pharmaceutical Response Project served as an independent, multidisciplinary collaboration to assess statewide hospital pharmaceutical response capabilities. Surveys of hospital pharmacy directors were conducted to determine pharmaceutical response preparedness to CBRNE threats. RESULTS: All 45 acute care hospitals in Maryland were surveyed, and responses were collected from 80% (36/45). Ninety-two percent (33/36) of hospitals had assessed pharmaceutical inventory with respect to biological agents, 92% (33/36) for chemical agents, and 67% (24/36) for radiological agents. However, only 64% (23/36) of hospitals reported an additional dedicated reserve supply for biological events, 67% (24/36) for chemical events, and 50% (18/36) for radiological events. More than 60% of the hospitals expected to receive assistance from the SNS within < or = 48 hours. CONCLUSIONS: From a pharmaceutical perspective, hospitals generally remain under-prepared for CBRNE threats and many expect SNS support before it realistically would be available. Collectively, limited antibiotics and other supplies are available to offer prophylaxis or treatment, suggesting that hospitals may have insufficient pharmaceutical surge supplies for a large-scale event. Although most state hospitals are improving pharmaceutical surge capabilities, further efforts are needed.     

A Comparison of Palliative Stenting or Emergent Surgery for Obstructing Incurable Colon Cancer

Background  

Acute colonic obstruction because of advanced colonic malignancy is a surgical emergency. Our aim was to review our experience with self-expanding metal stents (SEMS) compared to emergent surgery as the initial therapy for the management of patients with incurable obstructing colon cancer.     

Pilot study of safety and tolerability of inhaled hypertonic saline in infants with cystic fibrosis

Inhaled hypertonic saline (HS) positively affects both lung function and pulmonary exacerbations in children and adults with cystic fibrosis (CF). Early initiation of treatment may potentially reduce lung function decline and improve outcome of CF patients. However, the safety and tolerability of HS have not been established in infants and young children. We conducted a prospective trial of inhaled HS in infants with CF. Raised volume rapid thoracoabdominal compression (RVRTC) maneuvers were performed at baseline, 10 min after salbutamol inhalation and 15 min after inhalation of a 7% HS solution. Oxygen saturation, respiratory rate, heart rate, and cough frequency were recorded during each inhalation. A clinically important change in lung function was defined a priori as a change in FEV 0.5 of > or =20%. Thirteen infants (5 female) aged 25-140 weeks were enrolled in the study. Overall, there was no difference between FEV(0.5) or FEF(25-75) at baseline, after bronchodilator or after HS. Respiratory and heart rate as well as oxygen saturation remained stable during inhalation of the HS. Three infants had cough during inhalation; one of the infants woke up due to cough but recovered within 5 min. No other side effects were observed during or immediately after inhalation. There was no difference in microbiologic yield between pre- and post-HS throat swabs. In this pilot study, inhalation of HS was well tolerated in CF infants. These results support a study of the efficacy of HS in this age group.     

Cancer resistance in transgenic mice expressing the SAC module of Par-4

Prostate apoptosis response-4 (Par-4) is a tumor-suppressor protein that induces apoptosis in cancer cells, but not in normal/immortalized cells. The cancer-specific proapoptotic action of Par-4 is encoded in its centrally located SAC domain. We report here the characterization of a novel mouse model with ubiquitous expression of the SAC domain. Although SAC transgenic mice displayed normal development and life span, they were resistant to the growth of spontaneous, as well as oncogene-induced, autochthonous tumors. Resistance to tumorigenesis was linked to inhibition of nuclear factor-kappaB activity and induction of apoptosis by the SAC domain. Collectively, our findings provide genetic evidence that the SAC domain of Par-4 confers cancer resistance in transgenic mice without compromising normal viability or aging, and may have therapeutic significance.     

Pseudoarthrosis in heterotopic ossification in spinal cord-injured patients

Heterotopic ossification (HO) of proximal joints is a common complication of spinal cord injury, traumatic brain injury, and burns, and is also seen among an array of other clinical conditions. Of the patients with HO, 3-8% develop ankylosis of the joint involved. Although the etiology of HO is not known, the main goal in its management is to retain the maximum possible functional range of movement in the joint involved. Toward this end, surgical resection of HO with etidronate disodium treatment to mobilize ankylosed joints has been reported, as has forceful joint manipulation in head-injured adults with HO. This paper presents two cases of extensive HO formation around hip and knee joints in patients who developed pseudoarthrosis. Cinradiographic assessment of the joints involved revealed pseudoarthrosis formation at the same axis as the normal anatomical plane of the joint, thus permitting functional range of movement.     

Left main coronary artery disease in adults younger than 50 years: a comparison with older patients.

Left main coronary artery (LMCA) disease is a potentially lethal disease that can be effectively treated if it is recognized expeditiously. To determine whether clinical signs and symptoms vary with age, we examined data from 100 patients with angiographically significant LMCA disease (> or =50% stenosis). The majority of patients had myocardial infarction (32%) or Braunwald class I unstable angina (46%). There were no differences in initial symptoms, electrocardiographic findings (normal or only nonspecific changes in 52% of patients), or left ventricular function (normal or only mildly impaired in 76% of patients) between younger patients (< 50 yr; n = 29) and older patients (n = 71). Severe atherosclerosis was common in both groups. Risk factor profiles were different, however, in that diabetes mellitus (10% vs. 34%; P = 0.028) and hypertension (38% vs. 73%; P = 0.002) were less common and tobacco use was more common (79% vs. 39%; P <0.001) in younger patients. In summary, age influenced the risk factors associated with but not the clinical signs and symptoms of LMCAD.
