Cutaneous lesions associated with coronavirus-induced vasculitis in a cat with feline infectious peritonitis and concurrent feline immunodeficiency virus infection.

This report describes a clinical case of feline infectious peritonitis (FIP) with multisystemic involvement, including multiple nodular cutaneous lesions, in a cat that was co-infected with feline coronavirus and feline immunodeficiency virus. The skin lesions were caused by a pyogranulomatous-necrotising dermal phlebitis and periphlebitis. Immunohistology demonstrated the presence of coronavirus antigen in macrophages within these lesions. The pathogenesis of FIP involves a viral associated, disseminated phlebitis and periphlebitis which can arise at many sites. Target organs frequently include the eyes, abdominal organs, pleural and peritoneal membranes, and central nervous tissues, but cutaneous lesions have not previously been reported.

[Postoperative infection following craniotomy in adults].

OBJECTIVE: The aim of this study was to determine the risk factors for postoperative infection after craniotomy, a threat for the vital prognosis, in order to define specific prevention measures. METHOD AND PATIENTS: An open prospective study was made on all adult patients undergoing craniotomy and followed 30 days postoperatively. The infections were defined according to CDCA criteria. The parameters studied were: age, sex, ASA and Glasgow scores, neurosurgical history, the type, the moment and the surface of shaving, antibioprophylaxis, and the type and duration of surgery as well as its emergency level. RESULTS: One hundred and seventy patients were included. Thirty presented with an infection (17.6%), nine with a skull infection, 13 with meningitis, three with empyema, and two with osteitis. The risk factors identified thanks to a univariate analysis were the emergency level of surgery (P < 0.01), duration of surgery >200 min, and duration of stay in ICU >72 h (P < 0.02).

Exclusion of ill children from child-care centers in Israel.

The aim of the study was to examine criteria for ill children in child-care centers. A questionnaire on practices of exclusion/return of children according to specific signs and symptoms was mailed to the directors of care centers in central Israel. Thirty-six of the 60 questionnaires (60%) were returned by mail and the reminded were completed in personal visits to the CCCs achieving a response rate of 100%. About half (51.7%) used "common sense" and "personal feelings" to exclude children and to allow their return, and 29 (48.3%) used the guidelines of the Ministries of Education and Health or other authorities. The percentage of centers excluding children by signs/symptoms was as follows: high fever (>38 degrees C), 100%; low-grade fever, 76.7%; asthma exacerbation, 80.0%; heavy cough, 75.0%; eye discharge or conjunctivitis, 83.3%; diarrhea and vomiting more than twice per day, 100%; rash, 72.3%; otalgia, 46.7%; and infected skin lesion, 66.7%. Only four centers excluded children with head lice. Most centers required a physician's note on return of a child after high fever (76.7%), eye discharge or conjunctivitis (48.3%), and from 75 to 80%, respectively, for frequent vomiting and bloody or mucinous diarrhea. The results show that exclusion practices among child-care centers (CCCs) vary widely, suggesting the need for the establishment of a uniform exclusion and return policy in Israel, with distribution of clear, up-to-date guidelines on the prevention and control of communicable diseases to all day-care centers. In a simple way, this study identified attitudes concerning the exclusion/return of sick children in CCCs and was useful for the discussion of the related policy with CCCs responsible and national health and educational authorities.

Home remedies to control head lice: assessment of home remedies to control the human head louse, Pediculus humanus capitis (Anoplura: Pediculidae).

As the frequency and level of pediculicide resistance increases throughout the world, the need for novel solutions to control pediculosis has intensified. The development and registration of new pesticides has become so costly that many chemical companies are unwilling to pursue it and health-care providers now face a serious lack of new commercial pediculicides. Many infested people resort to using "home-remedy" approaches that have not been scientifically tested. In this article, we examined the potential value of six purportedly effective "home remedies" (vinegar, isopropyl alcohol, olive oil, mayonnaise, melted butter, and petroleum jelly) to treat head louse infestations and the likelihood of drowning lice by water submersion. Results indicated that only the application of petroleum jelly caused significant louse mortality but no treatment prevented lice from laying eggs. Most home remedy products did little to kill eggs, despite prolonged exposure. Petroleum jelly caused the greatest egg mortality, allowing only 6% to hatch. It was extremely difficult to drown lice, despite extended periods (i.e., 8 hr) of water submersion, suggesting that killing lice by depriving them of oxygen is inefficient. None of the home remedy products we surveyed was an effective means of louse control. This suggests that when treatment failure occurs, an increased amount of time and effort should be focused on alternative chemical pediculicides and/or manual louse removal (i.e., combing) rather than using any of these products.

Recurrent "unexplained" scalp swelling in an eighteen-month-old child: an atypical presentation of angioedema causing confusion with child abuse.

In this article, we demonstrate that angioedema may atypically present with noninflammatory scalp or facial swelling without recurrence on other parts of the body and without urticaria. In a young child, such a presentation exclusively with recurrent "unexplained" swellings over different parts of the scalp could erroneously be misconstrued as child abuse (blunt head trauma).

Disorders of the hair and scalp in children.

A wide variety of disorders involving the scalp and hair exist that may be encountered in the pediatric and adolescent population. An approach to the differential diagnosis of many of these conditions can be considered once the patient is found to have either alopecia, scaling, or tumors of the scalp. Certainly other causes of scalp or hair disease exist but the more common disorders can be appropriately considered in this manner.

Scalp and neck masses.

The evaluation of head and neck masses involves an orderly approach based on a careful history and accurate physical examination. Additional information sometimes is necessary using appropriate laboratory and radiologic investigation. In the vast majority of cases, surgery for biopsy or removal of the mass is required. Accurate preoperative diagnosis may require evaluation by appropriate consultants to avoid unnecessary or inappropriate operations.

[Scalp surgery in children: principles and therapeutic aspects].

Surgical treatment of the lesions of the scalp in children has specific objectives: excision of an extensive lesion using minimum operative procedures, hiding scar in the hair, correcting a wide and ungraceful scar. We reviewed our experience of 450 cases (1990-2000), and found that most common lesions in childhood were: sebaceous hamartoma, pigmentary naevus, post traumatic alopecia, aplasia cutis congenita and complicated hemangiomas. Different surgical procedures are discussed: excision, tissue expansion, hair grafts. Large excision can be performed before three months of life because of the good laxity of the scalp. Tissue expansion is particularly suited to the scalp. Aplasia cutis congenita is a special condition, with local vascular abnormalities: local flaps are prohibited. Hemangiomas may require early surgical treatment in the event of complications.

Histopathology of corneal leukoma and fibroma in the ACL syndrome.

Corneal tissues of four persons and a buccal fibroma from one of these persons with ACL syndrome, an autosomal dominant disorder, were evaluated clinically and microscopically. The corneal lesions appeared as a gray epithelial infiltrate over the cornea, destroying Bowman's membrane. Light and electron microscopic images of both types of lesions showed abnormal accumulation of granular mucopolysaccharide material and extensive aberrant orientation of collagen fibers. The authors postulate that the mucopolysaccharide accumulation is involved in the pathogenesis of the syndrome.

Multiple palisading granulomas in the scalp of an infant: a case report.

BACKGROUND: We describe an unusual lesion that represents an uncommon but important element in the differential diagnosis of subcutaneous scalp nodules in a child. CASE DESCRIPTION: A 1-year-old boy presented with two clusters of subcutaneous scalp nodules. The lesions increased in size and number. Computed tomography showed no changes in underlying bone. Findings on magnetic resonance imaging were nonspecific. Serologic and clinical evaluation showed no evidence of rheumatic disease. Complete excision of the nodules, together with adjacent fascia and galea, was performed. Histopathologic examination showed the lesions to be palisading granulomas; given the absence of rheumatic disease, these represented deep granuloma annulare, a benign condition. No recurrence has been observed in our patient. CONCLUSION: While we chose total excision because of preoperative concerns about a possible malignant tumor, some other authors have suggested that surgery be limited to confirmatory biopsy when a benign lesion such as palisading granuloma is strongly suspected.
