Tinea Capitis in Southeastern China: A 16-Year Survey

This survey was a retrospective of a 16-year (1993–2008) study on the incidence, clinical features, and etiological agents of tinea capitis mainly representing the Southeastern China. The diagnosis was confirmed by direct microscopic examination. Eight hundred and sixty-six patients with tinea capitis, 381 males (44%) and 485 females (56%), were enrolled in this study. Patients were between 20 days and 84 years old with an average of 10.5 years and the peak incidence was in the age group of 6–10 (48.5%). Five hundred and sixty-two patients (64.9%) were ectothrix and 303 patients (35.0%) were endothrix with only one patient was favus. The incidence of tinea capitis from 1993 was gradually increasing and reaching to its peak in 2001. Positive cultures of dermatophytes were obtained in 715 patients: Microsporum canis (62.4%) was predominant, followed by Trichophyton violaceum (19.0%), Trichophyton tousurans (9.8%). M. canis was the major pathogen for ectothrix infection, while T. violaceum and T. tousurans contributed to the most endothrix form. M. canis, T. violaceum, and T. rubrum were the major pathogens for kerion.     

Microsporum canis Infection in Three Familial Cases with Tinea Capitis and Tinea Corporis

We report a familial infection caused by Microsporum canis. The first two patients were a 30-year-old female and her son, a 5-year-old boy, who came in contact with a pet dog at a farm house. The boy then suffered from hair loss for 3 months. There were circular and patchy alopecia with diffuse scaling on his scalp. Meanwhile, his mother also developed patchy erythema and scaling on her face. Several weeks later, the boy’s sister, a 4-year-old girl, was noted to have inconspicuous scaly plaques in the center of her scalp. The development of tinea capitis in the two children and tinea corporis in their mother were diagnosed based on the positive KOH examination. Morphologic characteristics and sequencing of the internal transcribed spacers 1 and 2, amplified from primary culture isolates, confirmed that their infections were caused by the zoophilic M. canis. Repetitive sequence-based molecular typing using the DiversiLab system secreted enzymatic activity analysis, and antifungal susceptibility indicated that these isolates might share the same source. The boy and girl were cured by the treatment with oral itraconazole and topical naftifine–ketoconazole cream after washing the hair with 2 % ketoconazole shampoo, and their mother was successfully treated by terbinafine orally in combination with topical application of naftifine–ketoconazole cream.

Molecular Typing Study of the Microsporum Canis Strains Isolated from an Outbreak of Tinea Capitis in School

Tinea capitis is a dermatophyte infection of the scalp that occurs most often in prepubescent children. Tinea capitis may be transmitted by shared use of contaminated hairbrush, by contact with fomites or by direct physical contact with an infected person. Occasionally, outbreak of tinea capitis would happen under some special conditions. Last year, we found an outbreak of tinea capitis in a school due to Microsporum canis. In epidemiological study, we performed the prevalence survey to all of the exposed persons by physical examinations and mycological laboratory tests, including KOH preparation and fungal cultures. We also investigated the environment in the school. In molecular typing study of the M. canis isolated from patients and the environment, random primer amplification polymorphic DNA (RAPD) method, the specific amplification of subrepeat element in the ribosomal DNA nontranscribed spacer (NTS), and the analysis of DNA sequence in the intertranscribed spacer (ITS) of rDNA were performed. The total number of exposed children was seventy-one, among them forty-two were attacked by tinea capitis. The ratio between boy and girl was 13:1. The ages of the patients was ranged from 3.5 years old to 10 years old. Four patients bred cat or dog as pet. Most patients appeared noninflammatory type of tinea capitis and several patients were inflammatory type. Under microscopic examination the invaded hair were all ectothrix. The pathogens isolated from these patients were M. canis. And we also isolated M. canis from the carpet and the pillowcase in the school. The patterns of total strains of M. canis in the RAPD method and PCR amplification of the rDNA NTS region study were identical, and the isolates from patients and the environment contained the same DNA sequences in the ITS region. The outbreak of tinea capitis was caused by M. canis. The M. canis isolated from patients and from the environment were probably the same origin.     

Tinea Capitis in the Paediatric Population in Milan, Italy: The Emergence of Trichophyton violaceum

Tinea capitis (TC) is the most common type of dermatophytosis in children. The epidemiology of TC depends on the geographical areas, and it changes over time. The aim of the study is to determine the incidence of TC and to identify the causative species in children observed at Dermatology Outpatient Department of the University of Milan, Italy, between January 2004 and December 2011. Four hundred and eighty-six children with suspected dermatomycosis were observed; TC was the most prevalent dermatomycoses with 86 cases. The most common isolated dermatophyte in scalp lesions was Trichophyton violaceum with 33 cases. The most recent epidemiological Italian studies still show zoophilic fungi as primary cause of TC. We are the first medical team in Italy to demonstrate a dominance of anthropophilic fungi, in particular T. violaceum.

Self-Management Behavior in Patients with Type 2 Diabetes: A Cross-Sectional Survey in Western Urban China

Purpose

To investigate the current status of diabetic self-management behavior and the factors influencing this behavior in Chengdu, a typical city in western China.

Methods

We performed stratified sampling in 6 urban districts of Chengdu. We used questionnaires concerning self-management knowledge, self-management beliefs, self-management efficacy, social support, and self-management behavior to investigate patients with T2DM from August to November 2011. All of the data were analyzed using the SPSS 17.0 statistical package.

Results

We enrolled a total of 364 patients in the present study. The median score of self-management behavior was 111.00, the interquartile range was 100.00–119.00, and the index score was 77.77. Self-management was described as “good” in 46%, “fair” in 45%, and “poor” in 6% of patients. A multiple-factor analysis identified age (OR, 0.43; 95% CI, 0.20–0.91; P = 0.026), education in “foot care” (OR, 0.42; 95% CI, 0.18–0.99; P = 0.048), self-management knowledge (OR, 0.86; 95% CI, 0.80–0.92; P<0.001), self-management belief (OR, 0.92; 95% CI, 0.87–0.97; P = 0.002), self-efficacy (OR, 0.93; 95% CI, 0.90–0.96; P<0.001), and social support (OR, 0.62; 95% CI, 0.41–0.94; P = 0.023) as positive factors. Negative factors included diabetes duration (5–9 years: OR, 14.82; 95% CI, 1.64–133.73; P = 0.016; and ≥10 years: OR, 10.28; 95% CI, 1.06–99.79; P = 0.045) and hospitalization experience (OR, 2.96; 95% CI, 1.64–5.36; P<0.001).

Conclusion

We observed good self-management behavior in patients with T2DM in Chengdu. When self-management education is provided, age, education, knowledge, belief, self-efficacy, and social support should be considered to offer more appropriate intervention and to improve patients'' behavior.     

Onychomycosis Due to Neoscytalidium Treated with Oral Terbinafine, Ciclopirox Nail Lacquer and Nail Abrasion: A Pilot Study of 25 Patients

Background

Onychomycosis by Neoscytalidium constitutes chronic infection of the nails, and its frequency has increased in recent decades. Currently, no effective standard treatment exists and literature data remain scarce. This work aimed to conduct a pilot project of combined treatment for this infection.

Methods

Thirty patients were divided into three treatment groups: oral terbinafine plus ciclopirox nail lacquer twice a week; ciclopirox nail lacquer twice a week; and ciclopirox nail lacquer 5 days a week, all associated with nail abrasion when required, for 12 months, with 6 months posttreatment follow-up. Clinical and mycological criteria were used for evaluation.

Results

Twenty-five patients completed the study. Significant clinical lesion reduction in disease occurred in all three treatment groups: 21 patients (84 %) entered the study with more than 50 % of diseased nail plate, at the end of treatment, and at 6-month follow-up, 84 and 96 %, respectively, presented less than 25 % nail lesion. Negative microscopy was observed in 36 % of the patients at the end of treatment and in 24 % of the patients at 6-month follow-up. At treatment completion (12 months), culture was negative in 21 patients (84 %) and in 18 (72 %) at follow-up. It was not possible to establish any clinical or mycological statistical differences between groups (p > 0.05). Global medical evaluation upon treatment completion revealed that one patient (4 %) presented complete cure, 8 (32 %) presented partial cure, 16 (64 %) presented therapeutic failure. At the end of follow-up period, 6 patients (24 %) were considered to have recurrence/reinfection.

Conclusions

The results obtained at the 6-month period of follow-up showed marked improvement (96 % of clinical improvement and 72 % of negative culture) of the patients treated for onychomycosis caused by Neoscytalidium in the three tested groups with no statistical differences between them. Multicentric studies with greater number of patients enrolled are necessary to confirm these results.     

Parathyroidectomy Improves Survival In Patients with Severe Hyperparathyroidism: A Comparative Study

Background and objectives

Secondary hyperparathyroidism (SHPT) in CKD is associated with an increased risk for mortality, but definitive data showing that parathormone control decreases mortality is still lacking. This study aimed to compare the mortality of patients with severe SHPT submitted to parathyroidectomy(PTX) with those who did not have access to surgery.

Methods

This is a retrospective study in a cohort of 251 CKD patients with severe SHPT who were referred to a CKD-MBD Center for PTX from 2005 until 2012.

Results

Most of our patients had indication of PTX, but only 49% of them had access to this surgical procedure. After a mean follow-up of 23 months, 72 patients had died. Non-survivors were older; more often had diabetes, lower serum 25 vitamin D and mostly had not been submitted to surgery. The relative risk of death was lower in the PTX patients (0.428; 95% CI, 0.28 to 0.67; p<0.0001). After adjustments, mortality risk was dependent on age (1.04; 95% CI, 1.01 to 1.07; p = 0.002), 25 vitamin D (0.43; 95% CI, 0.24 to 0.81; p = 0.006) and no access to PTX (4.13; 95% CI, 2.16 to 7.88; p<0.0001). Results remained the same in a second model using the PTX date as the study start date for the PTX group.

Conclusions

Our data confirms the benefit of PTX on mortality in patients with severe SHPT. The high mortality encountered in our population is significant and urges the need to better treat these patients.

Patient-Led Versus Physician-Led Titration of Insulin Glargine in Patients with Uncontrolled Type 2 Diabetes: A Randomized Multinational Atlas Study

ObjectiveSelf-adjustment of insulin dose is commonly practiced in Western patients with type 2 diabetes but is usually not performed in Asian patients. This multinational, 24-week, randomized study compared patient-led with physician-led titration of once-daily insulin glargine in Asian patients with uncontrolled type 2 diabetes who were on 2 oral glucose-lowering agents.MethodsPatient-led (n = 275) or physician-led (n = 277) subjects followed the same dose-titration algorithm guided by self-monitored fasting blood glucose (FBG; target, 110 mg/dL [6.1 mmol/L]). The primary endpoint was change in mean glycated hemoglobin (HbA_1c) at week 24 in the patient-led versus physician-led titration groups.ResultsPatient-led titration resulted in a significantly higher drop in HbA_1c value at 24 weeks when compared with physician-led titration (− 1.40% vs. − 1.25%; mean difference, − 0.15; 95% confidence interval, − 0.29 to 0.00; P = .043). Mean decrease in FBG was greatest in the patient-led group (− 2.85 mmol/L vs. − 2.48 mmol/L; P = .001). The improvements in HbA_1c and FBG were consistent across countries, with similar improvements in treatment satisfaction in both groups. Mean daily insulin dose was higher in the patient-led group (28.9 units vs. 22.2 units; P < .001). Target HbA_1c of < 7.0% without severe hypoglycemia was achieved in 40.0% and 32.9% in the patient-led and physician-led groups, respectively (P = .086). Severe hypoglycemia was not different in the 2 groups (0.7%), with an increase in nocturnal and symptomatic hypoglycemia in the patient-led arm.ConclusionPatient-led insulin glargine titration achieved near-target blood glucose levels in Asian patients with uncontrolled type 2 diabetes who were on 2 oral glucose-lowering drugs, demonstrating that Asian patients can self-uptitrate insulin dose effectively when guided.

Radiotherapy Versus Radiosurgery in Treating Patients with Acromegaly: A Systematic Review and Meta-Analysis

Objective: When patients with acromegaly have residual disease following surgery, adjuvant radiation therapy is considered. Both stereotactic radiosurgery (SRS) and conventional fractionated radiotherapy (RT) are utilized. We conducted a systematic review and meta-analysis to synthesize the existing evidence and compare outcomes for SRS and RT in patients with acromegaly.Methods: We searched Medline In-Process & Other Non-Indexed Citations, MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus through April 2014 for studies in which SRS or RT were used in patients with acromegaly. Outcomes evaluated were serum insulin-like growth factor-I (IGF-I) and growth hormone (GH) levels, biochemical remission, all-cause mortality, hypopituitarism, headaches, and secondary malignancies. We pooled outcomes using a random-effects model.Results: The final search yielded 30 eligible studies assessing 2,464 patients. Compared to RT, SRS was associated with a nonsignificant increase in remission rate at the latest follow-up period (52% vs. 36%; P = .14) and a significantly lower follow-up IGF-I level (-409.72 μg/L vs. -102 μg/L, P = .002). SRS had a lower incidence of hypopituitarism than RT; however, the difference was not statistically significant (32% vs. 51%, respectively; P = .05).Conclusion: SRS may be associated with better biochemical remission, and it had a lower risk of hypopituitarism with at least 1 deficient axis when compared with RT; however, the confidence in such evidence is very low due to the noncomparative nature of the studies, high heterogeneity, and imprecision.Abbreviations: GH = growth hormone GKRS = gamma-knife radio-surgery IGF-I = insulin-like growth factor-I LINAC = linear accelerator RT = conventional radiotherapy SRS = stereotactic radiosurgery     

A Comparative Study on the Efficacy of Solifenacin Succinate in Patients with Urinary Frequency with or without Urgency

Objectives

Patients with overactive bladder (OAB) often have trouble perceiving urgency because of difficulties in distinguishing between urgency and desire to void. Empirical antimuscarinic treatment of patients with frequency only may be reasonable if conservative management has failed. We compared the efficacy of solifenacin in patients with frequency with or without urgency.

Materials and Methods

This multicenter, 12-week, open-label, comparative, non-inferiority clinical trial assessed whether the solifenacin efficacy for frequency without urgency is non-inferior to its efficacy for frequency with urgency. All patients had micturition frequency ≥8 voids/day with or without urgency. Primary efficacy variable: daily frequency change at 12 weeks relative to baseline. Secondary efficacy variables: change at 12 weeks relative to baseline in Patients'' Perception of Bladder Condition (PPBC), OAB Symptom Score (OABSS), and Benefit, Satisfaction, Willingness to continue (BSW) questionnaire.

Results

Of the 286 enrolled patients, 240 (83.9%) completed the study (without urgency n = 115; with urgency n = 125). Full dataset analysis revealed that the groups without and with urgency exhibited significant reductions in daily micturition frequency of −2.49±0.35 (mean ± standard error) and −2.63±0.37, respectively. The lower limit of the 95% two-sided CI of the comparison of the two group means was −1.14, which is smaller than the −0.8 margin of clinical equivalence. The two groups did not differ in improvement in PPBC, OABSS, or BSW scores. Both tolerated the treatment well.

Conclusions

It was not possible to verify that the solifenacin efficacy for frequency alone was non-inferior to its efficacy for OAB. Nevertheless, solifenacin tended to be effective for frequency regardless of urgency.

A Longitudinal Study of Thyroidectomized Patients in a Region of Northern Italy: Benign Versus Malignant Disease

ObjectiveThyroid disease is very common, particularly nodular goiter. Total thyroidectomy is a therapeutic option for both malignant and benign disease. The aim of the study was to evaluate the number of total thyroidectomy surgeries and the rate of benign and malignant histologic exams over the last decade.MethodsHospital discharge records in the Emilia Romagna region (Italy) that reported total thyroidectomy as the principal surgical procedure and included the relative histologic diagnosis were reviewed for the period 2000 to 2010. Mean increment and geometric mean of increments per year were calculated to evaluate differences over the years.ResultsMore than 25,000 patients underwent total thyroidectomy between 2000 and 2010. The total number of thyroidectomies increased over this period, with a mean increment of 7.16% per year. The percentage of malignancies among the total number of thyroidectomies increased from 26.1% (2000) to 39.9% (2010) (mean increment, 1.38% per year). Nontoxic multinodular goiter was the most frequent diagnosis, accounting for 36% of all thyroidectomies.ConclusionBetween 2000 and 2010, the proportion of patients thyroidectomized for benign disease progressively decreased, as documented by a lower thyroidectomy/malignancy ratio. Currently, about 60% of thyroid interventions are performed for benign pathology. Improved preoperative diagnostic accuracy and the availability of nonsurgical procedures will presumably further reduce the number of thyroidectomies with benign histologic diagnoses.

Studies in the Epidemiology of Tinea Pedis. IX: Tinea Pedis and Erythrasma in New Patients at a Chiropody Clinic

The feet of 259 new patients at a chiropody clinic were examined for tinea pedis, onychomycosis, and erythrasma: 23% of men and 4% of women were infected by dermatophytes, and the nails of seven males were infected by non-dermatophytes. Of 200 patients examined under Wood''s light 37% showed the coral-red fluorescence of erythrasma.Of the 259 patients, 9.7% were infected by Trichophyton interdigitale, 2.7% by T. rubrum, and 1.5% by Epidermophyton floccosum. Reasons are given, based on the method of selection of the patients, for supposing that T. interdigitale is still the dominant cause of tinea pedis in the population at large, despite figures from dermatological clinics suggesting the dominance of T. rubrum. The high incidence of infection in males compared with females corresponds with similar findings in school-children.     

Buruli Ulcer in South Western Nigeria: A Retrospective Cohort Study of Patients Treated in Benin

Nigeria is known to be endemic to Buruli ulcer, but epidemiological data are remarkably rare. Here, we present a large cohort of 127 PCR-confirmed M. ulcerans infection patients coming from Nigeria and treated in a neighbouring country, Benin. Severe lesions and delay of consultation are factors that should encourage establishment of a treatment centre in South Western Nigeria.
