Improving patient care by reporting problems with medical devices

Healthcare practitioners are the primary users of medical devices for direct patient care. As such, they are in the best position to recognize problems that result from the use of medical devices. The outcome of a device-related adverse event or product problem, as with any other medical product, can be serious and result in illness injury, or even death. The sooner that FDA learns about a problem, the sooner the agency can take action to protect patient and user safety. Healthcare practitioners are major contributors to the knowledge base related to device use and safety through astute monitoring, rapid identification of device-related problems, and reporting these problems. An understanding of the voluntary and mandatory mechanism of reporting will ensure that device problems are reported appropriately and in a timely manner. As the primary users of medical equipment for direct patient care, health care professionals have the training and expertise to improve patient care by reporting actual and suspected problems with medical devices.     

The therapist as patient: Special problems and considerations.

Argues that despite the awareness among mental health professionals of the need for the care of fellow practitioners, with emphasis on professional burnout and occupational counseling, the difficulties encountered by therapists in the treatment of their colleagues have been noticeably neglected. Based on experience treating colleagues, interventions and insights designed to avoid pitfalls while facilitating treatment are offered. It is suggested that the choice of a therapist should permit the patient a reasonable degree of social life-space anonymity, a sense of compatible treatment values and philosophy, and knowledge of and respect for the therapist's professional expertise. Factors that motivate a therapist to seek personal therapy are often more complex in reality than for the general patient population. Therapists who become patients have apprehensions that feelings emerging in their own psychotherapy will erode the carefully honed sense of self-as-healer/patients-as-wounded paradigm.

Pulmonary Nocardia otitidiscaviarum infection in a patient with chronic respiratory infection

We report a case of pulmonary Nocardia (N.) otitidiscaviarum infection in a 76-year-old man with chronic respiratory infection. The patient responded poorly to intravenous imipenem and oral minocycline, but later improved after treatment with trimethoprim-sulfamethoxazole. Pulmonary infection with N. otitidiscaviarum should be considered in the differential diagnosis of chronic respiratory infections. Further studies are needed to evaluate the correlation between species and drug susceptibility.     

Neuromuscular blockade with acute respiratory failure in a patient receiving cibenzoline

Cibenzoline is a class Ic antiarrhythmic agent that can be used to treat supraventricular arrhythmias. A case is reported of cibenzoline overdose in a patient with impaired renal function, leading not only to the usual cardiac and metabolic symptoms (bradycardia and hypoglycaemia), but also to a myastheniform syndrome with acute respiratory failure. Neuromuscular blockade was demonstrated by repetitive supramaximal stimulation of the median nerve, and diaphragmatic involvement was evidenced by applying the same protocol to the phrenic nerve. Muscle strength recovered as serum cibenzoline levels decreased, allowing the patient to be weaned from the ventilator. This observation suggests that cibenzoline, like other antiarrhythmic agents, can be responsible for neuromuscular blockade, and should therefore be used with caution in patients with neuromuscular and respiratory diseases or with impaired renal function.     

Food allergy in patients with respiratory allergy. Diagnostic possibilities and problems

In the past two years the authors examined 28 patients with abdominal complaints and allergic respiratory symptoms. Detailed internal, gastroenterological, allergological examinations were made. METHODS: 1 skin Prick-test (SPT) with inhalative and nutritive panel 2. measuring of food-specific (gliadin, alpha-lactalbumin beta-lactoglobulin, ovalbumin) IgG-antibody level detecting with ELISA method, 3. leukocyte migration inhibition (LMI) test against the same foodstuffs, 4. histological examination of the stomach and the duodenum especially for mucosal mastocytes (MMCs). RESULTS: 1. SPT was positive in 23/28 patients for inhalative, but in the 5 cases we did not identify any inhalative allergen. The SPT for the main foodstuffs were positive in 18 patients while in 3 other patients there was urtica only for the other antigens. 2. The food-specific IgG-antibody level was increased in 18/27 patients against one or more antigens. The SPTs and the antibody determination showed identity in 8/18 cases. 3. The LMI tests were positive against one or more main food-products in 23/27 cases. There was common positivity in respect of antigens (between LMI test and antibody identification) in 17 cases. Pathological immunological reactions were presented against the same main foodstuffs with at least two methods for flour in 11, for egg in 10 and for milk in 12 patients. Endoscopic examinations were performed in 27 cases. The number of the MMCs were increased in 22/27 patients. After a specific elimination diet open-food challenges were performed and they confirmed the results of the in vitro and in vivo examinations. CONCLUSION: It is common that the respiratory allergic symptoms in atopic patients accompanied with food allergy for the main foodstuffs caused not only more severe respiratory symptoms, but abdominal complaints too. In respect to the many positive LMI tests the late-type hypersensitivity have important pathogenetical role in it. This three methods together define well the main food-products, which can be antigens as well. The examination of the MMCs supports the local disturbance in the immunoregulatory system.     

Acute respiratory failure in the HIV-seropositive patient

Since approximately 40% to 65% of patients with AIDS will develop pulmonary disease, HIV-seropositive patients represent a large cohort of immunosuppressed individuals with the potential to progress to respiratory failure requiring mechanical ventilation and admission to the intensive care unit. This article reviews the cause, pathophysiology, diagnostic approach, and management of acute respiratory failure requiring mechanical ventilation in HIV-seropositive patients. Prognostic factors and survival rates for episodes of respiratory failure are also discussed. In addition, an overview of acute respiratory failure in pediatric AIDS patients is presented.     

Different O-glycosylation of respiratory mucin glycopeptides from a patient with cystic fibrosis

The O-linked oligosaccharides from three fractions of highly glycosylated mucin glycopeptides obtained from sputum of a patient with cystic fibrosis were characterized and compared regarding size, composition, sequence and when possible linkage positions. Neutral and sialic acid-containing glycans were permethylated and analyzed by high-temperature GC-MS and MALDI-MS, showing more than 60 different oligosaccharides with a size of up to 15 monosaccharide units. Some of the observed oligosaccharides are novel for respiratory secretions, one being a trifucosylated heptasaccharide with the proposed structure: Fuc-Gal-4(Fuc-3)GlcNAc-(Fuc-)Gal-3GalNAcol. The glycosylation of two of the glycopeptide fractions was similar with regard to the neutral and sialylated oligosaccharides despite their different origins from the sol or gel phase. Analysis of the sulfated oligosaccharides by FAB-MS/MS indicated that the gel fraction contained C-6 linked sulfate groups while the two sol fractions also contained C-3 linked sulfate. The results suggest the presence of different glycosylated mucin domains, probably originating from different mucin glycoforms and/or apoproteins in the airway of cystic fibrosis patients.     

Aspiration-drainage of an emphysematous bulla in a patient with severe respiratory insufficiency

The authors report the case of a patient with severe alveolar hypoventilation, with a large emphysematous bulla in the upper part of the right pulmonary field. The drainage aspiration of the bulla as a life saving technique greatly improved the respiratory function. Blood gases reverted to normal and the bullae disappeared. Literature reviewing. Discussion of radiological and functional criteria of compressing the pulmonary parenchyma around the bulla.     

The sepsis syndrome and the cancer patient: respiratory management and active physiotherapy

We describe the case of a 46-year-old man with lung cancer and simultaneous solitary adrenal metastases. Adrenalectomy was performed 12 weeks after lung resection through a right subcostal laparotomy. Treatment was complemented with chemotherapy. Twelve months after adrenalectomy the patient was found free of signs of disease and was in satisfactory condition. The advantages of and indications for surgical resection of suprarenal metastasis are discussed in the light of published literature. In some cases, survival may improve with exeresis and chemotherapy.     

Noninvasive mechanical ventilation in a patient with respiratory failure after hematopoietic progenitor transplantation

Respiratory failure requiring orotracheal intubation (OTI) and mechanical ventilation (MV) is almost always a fatal complication in patients who undergo hematopoietic progenitor transplantation (HPT). We present the case of a woman who suffered respiratory failure with bilateral infiltrates on a chest X-ray taken on day +14 following autologous bone marrow transplantation. We managed the patient satisfactorily with noninvasive ventilation, avoiding OTI. We believe that patients with non-progressive pulmonary lesions and without multiple system organ failure, may be correctly managed with noninvasive positive-pressure ventilation (NPPV).     

Usefulness of bronchoalveolar lavage in the renal transplant patient with suspected respiratory infection

In this retrospective study we aimed to assess the diagnostic yield of bronchoalveolar lavage (BAL) in kidney transplant patients who were suspected of having severe respiratory infection or in whom empirical antibiotic treatment had failed. All BAL procedures performed on kidney transplanted patients suspected of having respiratory infections between January 1, 1988 and July 31, 1996 were analyzed. BAL was carried out in the standard way and samples were sent for cytologic and bacteriologic study. Thirty-three patients with a mean age of 48.5 years were enrolled. All had been receiving immunosuppressive treatment and the mean time following transplantation was 320 days. Thirty-one had received antibiotic treatment before BAL. BAL was positive for 21 of the 33 patients (64%). Twenty-two pathogens were identified: 6 Pneumocystis carinii, 4 Cytomegalovirus, 3 Mycobacterium tuberculosis, 2 Aspergillus fumigatus, 2 Herpes simplex type I, 1 Streptococcus pneumoniae, 1 Staphylococcus aureus, 1 Streptococcus mitis, 1 Legionella pneumophila, 1 Legionella longbeachae. BAL was negative for 12 patients, of whom 8 were tentatively diagnosed of bacterial infection, 3 of acute pulmonary edema and one of pulmonary infarction. Based on the results, therapy was changed for 20 patients (61%), 19 (58%) because an unsuspected pathogen was identified and 1 because treatment could be simplified. The diagnostic yield of BAL is high (64%) in kidney transplant patients suspected of respiratory infection and is useful for managing such cases, as evidenced by the fact that a high proportion (19/33) of our patients were infected by pathogens not covered by empirical treatment.     

The patient with a tracheostomy

For the treatment of certain specific diseases, a tracheostomy is a required procedure in order to keep the patient's air passageways open. The nurse's care must ensure this permeability is maintained and infections avoided while serving to aid both the patient and his/her family to adapt as best as possible to the conditions caused by the intervention. Treatment Plan details will be drawn up based on each individual patient's diagnosis.     

The elderly patient with multiple complaints

"Thick chart" patients often have both a stated and an unstated agenda. Failure to recognize the latter can create a crisis of confidence that may prompt the patient to search for a more empathetic physician. So in addition to making a diagnosis in the face of confusing data, the physician must establish confidence by listening carefully and involving the patient in treatment decisions.     

Oral and dental problems in the organ transplant patient

The number of people receiving organ transplants has dramatically increased over the last decade. It is now likely that a dental surgeon will come across patients who have undergone transplantation. This paper considers the particular problems that these patients are likely to present their general dental practitioners.
