Infantile Digital Fibroma Treated With Mohs Micrographic Surgery

BACKGROUND: Infantile digital fibroma (IDF) is a rare benign fibrous tumor of childhood that frequently recurs despite local excision. Conservative, nonsurgical management may result in regression and/or joint deformity. OBJECTIVE: To describe the histologic features of IDF and discuss a case excised using Mohs micrographic surgery (MMS). METHODS: Case report and review of the clinical, histologic, and ultrastructural features. RESULTS: Characteristic inclusion bodies of actin were identified with hematoxylin and eosin, Masson's trichrome, and rapid actin immunostain. The tumor was debulked and the majority was removed after one stage of MMS, except where the deep margin approached the joint space. The defect healed by secondary intention. At 2 years the patient had no recurrence or functional joint deformity. CONCLUSION: MMS is a surgical treatment option for IDF.     

Smoking and coffee intake following alcohol withdrawal in alcoholic inpatients

The aim of this study was to assess alcoholic inpatients' smoking and coffee intake variation following withdrawal. Only moderate smokers (less than 30 cigarettes/day) showed a significant increase of cigarette consumption after alcohol withdrawal. However, their urinary cotinine level did not vary, suggesting a behavioral, and not biological, compensation through smoking following alcohol withdrawal. Heavy smokers (30 cigarettes/day or more) showed no significant clinical or biological variation of smoking behavior. Coffee consumption increased after alcohol withdrawal in all patients, irrespective of smoking habits.     

Management of catheter-related infections in pediatric patients

Broviac catheters are commonly used to provide parenteral nutrition and access for infusion of blood products and drugs to pediatric patients. Sepsis is the most common serious complication of continued catheter use. Although removal of the catheter is generally recommended when it becomes contaminated, it may not be feasible to do so without compromising patient care. We evaluated the management of catheter-related infections in pediatric patients with and without removal of catheter. Seventy-seven episodes of catheter sepsis were evaluated in 61 pediatric patients; 24 were neonates and 37 were older children. The catheters were used for multiple purposes in 75% of cases. The most common microorganisms isolated were Staphylococcus epidermidis in 26%, Klebsiella pneumoniae in 9%, and Streptococcus viridans in 8% of cases; other pathogens included group D Enterococcus, Staphylococcus aureus, and Escherichia coli. Pseudomonas aeruginosa was isolated in four older children. Thirty-five patients were treated with antibiotics without catheter removal. Thirty patients received appropriate antibiotic therapy based on the susceptibility data. Twenty-six of these 30 patients responded within 5 days of therapy whereas the others required 15-39 days of treatment. Lack of response was mainly associated with the presence of abscess, immunocompromised status, and organisms P. aeruginosa and Candida albicans. Based on the sensitivity and minimum inhibitory concentration data, a combined regimen of gentamicin and vancomycin would be an effective initial therapy. These findings suggest that (1) catheter sepsis can be managed with appropriate antibiotics, and (2) when continued use of Broviac catheter is desired, a trial of antibiotic therapy should be attempted before catheter removal.     

Overexpression/amplification of HER-2/neu is uncommon in hepatocellular carcinoma

BACKGROUND： Hepatocellular carcinoma （HCC） is one of the most prevalent fatal cancers in the world. Despite advances in early diagnosis and improvements in surgical techniques, the survival of patients with HCC even after resection is poor because of the high incidence of recurrences. Therefore, the identification of prognostic factors may be helpful in the development of new treatment protocols. AIMS： To investigate HER-2/neu status in HCC by immunohistochemistry （IHC） and fluorescence in situ hybridisation （FISH）, and to explore the possibility of using trastuzumab in the treatment of HCC. METH ODS： Eight hundred and sixty eight surgical samples from patients with primary HCC were examined for their HER-2/neu status. IHC for HER-2/neu was performed with the HercepTest kit; FISH analysis was performed with the PathVysion HER-2 DNA probe kit. The correlations between HER-2/neu overexpression and clinicopathological characteristics were analysed statistically. RESULTS： HER-2/neu overexpression was detected in 21 （2.42%） of the 868 primary HCCs. Only one specimen showed HER-2/neu gene amplification by FISH. No significant associations were found between HER-2/neu overexpression and the clinicopathological parameters. CONCLUSIONS： There is a low frequency of HER-2/neu overexpression/amplification in HCC. There appears to be no role for HER-2/neu as a prognostic marker and no benefit of anti-HER-2/neu trastuzumab treatment in patients with HCC.     

Acute pustulosis of the legs in diverticulitis with sigmoid stenosis: an overlap between bowel-associated dermatosis–arthritis syndrome and pustular pyoderma gangrenosum

BACKGROUND: Bowel-associated dermatosis-arthritis syndrome denotes the occurrence of diarrhoea with arthritis and skin lesions related to bowel disease with or without bowel bypass. In this condition, the histological finding of cutaneous aseptic neutrophilic cell infiltrate is non-specific and common to a wide spectrum of neutrophilic dermatoses, including pyoderma gangrenosum. OBSERVATION: We describe a 78-year-old woman with fever, abdominal discomfort and arthralgias, who developed grouped pustular lesions on her shins with histologically spongiform pustule formation. Aetiological assessment disclosed diverticular disease with sigmoid stenosis. CONCLUSION: Although clinical and histological features in our case fit the diagnosis of bowel-associated dermatosis-arthritis syndrome, they may also correspond to a pustular variant of pyoderma gangrenosum. Our observation raises the question of the nosological classification of bowel-associated dermatosis-arthritis syndrome within the spectrum of neutrophilic diseases.     

Perforation Rates for Nonsterile Examination Gloves in Routine Dermatologic Procedures

BACKGROUND: Low cost, nonsterile examination gloves are used routinely to perform various dermatologic procedures. OBJECTIVE: To evaluate the perforation rate of nonsterile examination gloves in routine dermatologic procedures. METHODS: Three hundred fifty nonsterile latex examination gloves used to perform shave biopsies were evaluated for perforations using an air inflation/water submersion method. Ninety gloves, which were intentionally perforated with a 30-gauge needle, were used as controls to assess our evaluation method. RESULTS: Eight of the 350 gloves were found to have a perforation, which corresponds to a 2.3% perforation rate. Seven of the eight perforations were found in the web space between the second and third finger sleeves, with one being an obvious manufacturing error. All 90 perforations of the control group were correctly identified. CONCLUSION: There appears to be a very low risk of glove perforation when nonsterile examination gloves are used in routine dermatologic procedures.     

Status of child health worldwide.

OBJECTIVE: The objective of this article is to summarize some of the facts about child health and goals of international health organizations. DATA SOURCES: The sources included the publications of World Health Organization's (WHO), United Nations Children Fund, and United Nations Educational, Scientific, and Cultural Organizations; and journal articles. DATA EXTRACTION: Data on areas related to child health were obtained from various publications. DATA SYNTHESIS: Although childhood mortality continues to fall worldwide, nearly 14 million children under five years of age still die annually in developing countries. Diarrhea, measles, tetanus, pertussis, pneumonia, and malnutrition are preventable and treatable and yet account for the majority of deaths. AIDS has begun to substantially affect the pediatric population. It is encouraging that the WHO's goal to immunize 80 percent of all children in the developing world has been met. The World Summit for Children, in consultation with governments of 159 countries, and the agencies of the United Nations, has adopted new goals to be attained by the year 2000. CONCLUSIONS: It is hoped that governmental and nongovernmental agencies will embrace these goals and formulate plans to markedly reduce childhood morbidity and mortality.
