Spiritual interventions provided by mental health nurses.

This descriptive qualitative study explored the spiritual nursing interventions provided by mental health nurses. Fifty mental health nurses responded to open-ended interrogative statements to report on nursing interventions in three situations that supported the spiritual needs of patients and families. Their responses were grouped into four categories, nurses being with the client, doing for the client, encouraging the client to look inward, and encouraging the client to look outward. Being with was demonstrated through the presence of the nurse. Doing for included interventions performed on the client's behalf and included the nurses using time, people, and space to provide care. Clients were encouraged to look inward for strength and look outward for people and objects that could be resources for them. A serendipitous findings was that mental health nurses were able to describe the ideal spiritual interventions but reported fewer instances of actually having intervened.

Vaccination of black-footed ferret (Mustela nigripes) x Siberian polecat (M. eversmanni) hybrids and domestic ferrets (M. putorius furo)against canine distemper.

An inactivated canine distemper vaccine with adjuvant and a modified-live virus (MLV) vaccine were evaluated using black-footed ferret (Mustegla nigripes) x Siberian polecat (Mustela eversmanni) hybrids us surrogates for endangered black-footed ferrets. For comparative purposes, we also vaccinated domestic ferrets (Mustela putorius furo) with the MLV vaccine. Response to vaccination was measured by clinical observation, hematology, dynamics of serum virus neutralizing antibodies, and challenge with virulent canine distemper virus. No clinical signs attributable to the vaccines were observed. Transient leukopenia occurred in hybrid ferrets that received MLV vaccine and there was marked lymphopenia for approximately 52 days post-vaccination. Lymphopenia was present for approximately 21 days in domestic ferrets vaccinated with MLV vaccine. Neutralizing antibodies against canine distemper virus were detected 14 days post-vaccination in hybrids receiving MLV vaccine and most titers were > 1:1024 for the 791 days of the study. Antibody titers in hybrids vaccinated with the inactivated vaccine were significantly lower. All eight hybrid ferrets that received MLV vaccine survived challenge with virulent canine distemper virus without clinical disease. However, one of seven hybrids vaccinated with the inactivated vaccine developed canine distemper and was euthanized; two other hybrids became clinically ill but survived. The MLV vaccine may be useful in prevention of canine distemper in black-footed ferrets, but until additional studies of efficacy and safety are completed, use of the inactivated vaccine is appropriate.

Subepidermal vesiculobullous filarial dermatitis in free-ranging American badgers (Taxidea taxus).

Skin and superficial lymph nodes from the 65 juvenile (< 1 year old) and adult free-ranging American badgers (Taxidea taxus) of both sexes that were killed from late July to late October 1991 as part of the recovery program for the endangered black-footed ferret (Mustela nigripes) were examined for evidence of Filaria taxideae. Fifty-one badgers (51/64, 80%) were infected. Both adult badgers (30/32, 94%) and juvenile badgers (21/32, 67%) were infected by adult filarial worms, which occurred most commonly in subcutaneous tissues of the inguinal area, proximal thigh, and ventral abdomen. Sections of formalin-fixed skin and, from many badgers, subcutaneous lymph nodes were stained with hematoxylin and eosin, Jones' methenamine silver (for basement membrane), and an avidin biotin peroxidase complex method (for factor VIII-related antigen). Superficial dermatitis attributable to embryonated filarial ova and larvae was present in 26/64 badgers (41%), all of them adult (> 1 year old). Acute lesions consisted of multifocal vesiculobullous dermoepidermal separation and superficial perivascular dermatitis. Ultrastructural examination and Jones' silver-stained sections revealed separation between basal keratinocytes and the basal lamina (subepidermal vesiculation). Older lesions consisted of ulcerative superficial granulomatous dermatitis associated with ova and larvae. Multifocal granulomatous endolymphangitis, which involved afferent lymphatics of subcutaneous lymph nodes, was associated with viable as well as degenerative ova and larvae. Adult filarial worms were found in the subcutis alone and did not provoke an inflammatory reaction.

Laser-assisted vasectomy reversal: experience in 32 patients.

A Food and Drug Administration approved protocol using a microsurgical carbon dioxide laser to assist in vasectomy reversal was instituted in January 1987. Between January 1987 and December 1988 the procedure was performed on 32 patients, 31 of whom submitted sperm and were available to evaluate. Success rates for sperm in the ejaculate in patients who underwent vasectomy less than 10 years previously were excellent, approaching 95%. The pregnancy rate in this group was 35%. In patients whose vasectomy was performed more than 10 years before reversal the results were much poorer. The success rate for sperm in the ejaculate was only 36% and the pregnancy rate was only 9%. The advantage of laser-assisted vasectomy reversal is that it is a simpler technical procedure that requires considerably less time than a 2-layer microsurgical technique. There were no significant complications, sperm granuloma, or even significant swelling or hematoma in any patient operated upon. Laser-assisted vasectomy reversal is at least equal to conventional microsurgical techniques and definitely easier to perform surgically.
