RESUMEN

In March 2023, the European Forum for Research and Education in Allergy and Airways diseases (EUFOREA) organized its bi-annual Summit in Brussels with expert panel members of EUFOREA, representatives of the EUFOREA patient advisory board, and the EUFOREA board and management teams. Its aim was to define the research, educational and advocacy initiatives to be developed by EUFOREA over the next 2 years until the 10th anniversary in 2025. EUFOREA is an international non-for-profit organization forming an alliance of all stakeholders dedicated to reducing the prevalence and burden of chronic allergic and respiratory diseases via research, education, and advocacy. Based on its medical scientific core competency, EUFOREA offers an evidence-supported platform to introduce innovation and education in healthcare leading to optimal patient care, bridging the gap between latest scientific evidence and daily practice. Aligned with the mission of improving health care, the expert panels of asthma, allergic rhinitis (AR), chronic rhinosinusitis (CRS) & European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS), allergen immunotherapy (AIT) and paediatrics have proposed and elaborated a variety of activities that correspond to major unmet needs in the allergy and respiratory field. The current report provides a concise overview of the achievements, ambitions, and action plan of EUFOREA for the future, allowing all stakeholders in the allergy and respiratory field to be up-dated and inspired to join forces in Europe and beyond.

RESUMEN

In endeavouring to mitigate the spread of the SARS-CoV-2 virus, a concerning practice of spraying individuals with disinfectant via so-called 'disinfection tunnels' has come to light. The Allergy Society of South Africa supports the World Health Organization in strongly condemning all human spraying, owing to lack of efficacy and potential dangers, especially to patients with coexisting allergic conditions.

RESUMEN

BACKGROUND: There are no previous data on tolerance development in children with atopic dermatitis (AD) and concomitant food allergy in low- and middle-income settings. OBJECTIVES: To determine the rate of tolerance acquisition to egg and peanut 5 years after diagnosing food allergies in South African (SA) children with AD, and to explore factors influencing tolerance acquisition. METHODS: Five years after first diagnosing food allergy in 37 SA children with egg and/or peanut allergy, they were reassessed for their allergies by questionnaire, skin-prick tests (SPTs) and ImmunoCAP-specific IgE (sIgE) tests (Thermo Fisher Scientific/Phadia, Sweden) to egg white, ovomucoid, peanut and Arachis hypogaea allergen 2 (Ara h 2), and incremental food challenges. RESULTS: Eighteen of 25 originally egg-allergic patients and 19 of 24 originally peanut-allergic children were followed up at a median age of 8 years and 3 months and 9 years and 6 months, respectively. A high percentage of children (72.2%) outgrew their egg allergy, and 15.8% outgrew their peanut allergy. Allergic comorbidity remained high, with asthma increasing over time, and AD remaining moderate in severity in the cohort overall. At diagnosis, sIgE egg white ≤9.0 kU/L and sIgE ovomucoid ≤2.0 kU/L were associated with tolerance development to egg 5 years later. At follow-up, sIgE egg white ≤0.70 kU/L, sIgE ovomucoid ≤0.16 kU/L, SPT egg-white extract ≤1 mm and SPT fresh egg ≤5 mm were associated with tolerance. At diagnosis, sIgE Ara h 2 ≤1.7 kU/L and SPT peanut ≤10 mm were associated with tolerance development to peanut 5 years later. At follow-up, sIgE peanut ≤0.22 kU/L, sIgE Ara h 2 ≤0.18 kU/L and SPT peanut ≤5.5 mm were associated with tolerance. CONCLUSIONS: Egg allergy was outgrown in 72.2% and peanut allergy in 15.8% of SA children 5 years after diagnosis of AD. This is in keeping with findings derived from studies in higher socioeconomic settings, and can help to guide the counselling of patients with allergies to these foods of high nutritional value.

RESUMEN

BACKGROUND: Atopic dermatitis (AD) is an early and important step in the propagation of the allergic march, enhancing food and respiratory allergies via epicutaneous sensitisation to allergens. OBJECTIVES: To determine the prevalence and patterns of aeroallergen sensitisation, asthma and allergic rhinitis in South African (SA) children with AD. METHODS: This was a prospective, observational study in a paediatric university hospital in Cape Town, SA. Children with moderate to severe AD, aged 6 months - 10 years, were recruited randomly and investigated for food sensitisation and allergy. They were assessed for sensitisation to aeroallergens by the immuno solid-phase allergen chip test. House-dust mite DerP and DerF, dust mite Eur m, Timothy grass, Bermuda grass, tree pollen, mould (Alternaria), cat and dog sensitisation patterns were analysed. Symptoms of asthma and allergic rhinitis were elicited using a questionnaire modified from the International Study of Asthma and Allergies in Childhood study questions. RESULTS: One hundred participants (59 black Africans and 41 of mixed ethnicity) were enrolled (median age 42 months). Of the participants, 39% had symptoms of asthma and 53% symptoms of allergic rhinitis; 89% tested positive to at least one aeroallergen, most commonly house-dust mite DerP or DerF (81%), dust mite Eur m (51%), Timothy grass (36%) and cat (35%). Asthma, allergic rhinitis and aeroallergen sensitisation all increased with increasing age, while food allergy decreased with age. Food allergy was not an independent risk factor for respiratory allergies. Children were sensitised to indoor allergens (house-dust mite, pets) from an early age, while pollen allergies increased with age. CONCLUSIONS: In this cohort of SA children with moderate to severe AD, comorbidity with respiratory allergies was high. The prevalence of respiratory allergies increased with age while food allergy decreased with age, in keeping with the pattern of the allergic march. Seasonal allergies increased with age, while house-dust mite and pet allergy peaked in younger children, in keeping with early exposure via a defective skin barrier. Early and effective restoration of the skin barrier in AD may be a target for reducing aeroallergen-related diseases.

RESUMEN

BACKGROUND: Approximately 153 million children worldwide are orphaned and vulnerable to potentially traumatic events (PTEs). Gender differences in PTEs in low- and middle-income countries (LMIC) are not well-understood, although support services and prevention programs often primarily involve girls. METHODS: The Positive Outcomes for Orphans study used a two-stage, cluster-randomized sampling design to identify 2837 orphaned and separated children (OSC) in five LMIC in sub-Saharan Africa and Asia. We examined self-reported prevalence and incidence of several PTE types, including physical and sexual abuse, among 2235 children who were ≥10 years at baseline or follow-up, with a focus on gender comparisons. RESULTS: Lifetime prevalence by age 13 of any PTE other than loss of a parent was similar in both boys [91.7% (95% confidence interval (CI) (85.0-95.5)] and girls [90.3% CI (84.2-94.1)] in institutional-based care, and boys [92.0% (CI 89.0-94.2)] and girls [92.9% CI (89.8-95.1)] in family-based care; annual incidence was similarly comparable between institution dwelling boys [23.6% CI (19.1, -29.3)] and girls [23.6% CI (18.6, -30.0)], as well as between family-dwelling boys [30.7% CI (28.0, -33.6)] and girls [29.3% CI (26.8,-32.0)]. Physical and sexual abuse had the highest overall annual incidence of any trauma type for institution-based OSC [12.9% CI (9.6-17.4)] and family-based OSC [19.4% CI (14.5-26.1)], although estimates in each setting were no different between genders. CONCLUSION: Prevalence and annual incidence of PTEs were high among OSC in general, but gender-specific estimates were comparable. Although support services and prevention programs are essential for female OSC, programs for male OSC are equally important.

RESUMEN

The prevalence of food allergy is increasing worldwide and is an important cause of anaphylaxis. There are no local South African food allergy guidelines. This document was devised by the Allergy Society of South Africa (ALLSA), the South African Gastroenterology Society (SAGES) and the Association for Dietetics in South Africa (ADSA). Subjects may have reactions to more than one food, and different types and severity of reactions to different foods may coexist in one individual. A detailed history directed at identifying the type and severity of possible reactions is essential for every food allergen under consideration. Skin-prick tests and specific immunoglobulin E (IgE) (ImmunoCAP) tests prove IgE sensitisation rather than clinical reactivity. The magnitude of sensitisation combined with the history may be sufficient to ascribe causality, but where this is not possible an incremental oral food challenge may be required to assess tolerance or clinical allergy. For milder non-IgE-mediated conditions a diagnostic elimination diet may be followed with food re-introduction at home to assess causality. The primary therapy for food allergy is strict avoidance of the offending food/s, taking into account nutritional status and provision of alternative sources of nutrients. Acute management of severe reactions requires prompt intramuscular administration of adrenaline 0.01 mg/kg and basic resuscitation. Adjunctive therapy includes antihistamines, bronchodilators and corticosteroids. Subjects with food allergy require risk assessment and those at increased risk for future severe reactions require the implementation of risk-reduction strategies, including education of the patient, families and all caregivers (including teachers), the provision of a written emergency action plan, a MedicAlert necklace or bracelet and injectable adrenaline (preferably via auto-injector) where necessary.

RESUMEN

Conditioned defeat (CD) is a behavioral response that occurs in Syrian hamsters after they experience social defeat. Subsequently, defeated hamsters no longer produce territorial aggression but instead exhibit heightened levels of avoidance and submission, even when confronted with a smaller, non-aggressive intruder. Dopamine in the nucleus accumbens is hypothesized to act as a signal of salience for both rewarding and aversive stimuli to promote memory formation and appropriate behavioral responses to significant events. The purpose of the present study was to test the hypothesis that dopamine in the nucleus accumbens modulates the acquisition and expression of behavioral responses to social defeat. In Experiment 1, bilateral infusion of the non-specific D1/D2 receptor antagonist cis(z)flupenthixol (3.75 µg/150 nl saline) into the nucleus accumbens 5 min prior to defeat training significantly reduced submissive and defensive behavior expressed 24h later in response to a non-aggressive intruder. In Experiment 2, infusion of 3.75 µg cis-(Z)-flupenthixol 5 min before conditioned defeat testing with a non-aggressive intruder significantly increased aggressive behavior in drug-infused subjects. In Experiment 3, we found that the effect of cis-(Z)-flupenthixol on aggression was specific to defeated animals as infusion of drug into the nucleus accumbens of non-defeated animals did not significantly alter their behavior in response to a non-aggressive intruder. These data demonstrate that dopamine in the nucleus accumbens modulates both acquisition and expression of social stress-induced behavioral changes and suggest that the nucleus accumbens plays an important role in the suppression of aggression that is observed after social defeat.

RESUMEN

AIM: To compare pancreatic cancer incidence and diagnostic evaluation among patients initiating dipeptidyl-peptidase-4 (DPP-4) inhibitor treatment with those initiating sulfonylureas (SU) and thiazolidinediones (TZD). METHODS: Medicare claims data were examined in a new-user active-comparator cohort study. Patients >65 years with no prescriptions for DPP-4 inhibitors, SU or TZD at baseline were included if they had at least two claims for the same drug within 180 days. Using an as-treated approach and propensity score-adjusted Cox models, we estimated the hazard ratios (HRs) and 95% confidence intervals (CIs) for pancreatic cancer. Diagnostic evaluations were compared using risk ratios. RESULTS: In the DPP-4 inhibitor versus SU comparison, there were 18 179 patients who initiated treatment with DPP-4 inhibitors, of whom 26 developed pancreatic cancer (interquartile range follow-up 5-18 months). In the DPP-4 inhibitor versus TZD comparison there were 29 366 people initiating DPP-4 inhibitor treatment and 52 of these developed pancreatic cancer. The risk of pancreatic cancer with DPP-4 inhibitor treatment was lower relative to SU treatment (HR: 0.6, CI: 0.4-0.9) and similar to TZD treatment (HR: 1.0, 95% CI: 0.7-1.4). After the first 6 months of follow-up were excluded to reduce the potential for reverse causality, the results were not altered. The probability of diagnostic evaluation after commencing DPP-4 inhibitor treatment (79.3%) was similar to that for TZD (74.1%, risk ratio 1.06, 95% CI: 1.05-1.07) and SU (74.6%) (risk ratio 1.06, 95% CI: 1.05-1.07). The probability of diagnostic evaluation before the index date (date of initiating treatment) was ∼80% for all cohorts. CONCLUSION: Although the present study was limited by sample size and the observed duration of treatment in the USA, our well-controlled population-based study suggests there is no higher short-term pancreatic cancer risk with DPP-4 inhibitor treatment relative to SU or TZD treatment.

RESUMEN

OBJECTIVES: To investigate the efficacy and safety of intraoperative cell salvage with autotransfusion using leukocyte reduction filters in patients undergoing radical retropubic prostatectomy (RRP). METHODS: Between September 1996 and March 1999, 62 patients (age range 48 to 70 years) with clinically localized prostate cancer underwent RRP with intraoperative cell salvage as the sole blood management technique. Salvaged blood was passed through a leukocyte reduction filter before autotransfusion. The 62 cell salvage patients were compared with a cohort who predonated 1 to 3 U autologous blood (n = 101). The estimated blood loss, preoperative and postoperative hematocrit, need for homologous transfusion, and biochemical recurrence rates were compared between the two groups. The progression-free survival rates were compared using the Kaplan-Meier method. RESULTS: No difference was found in preoperative prostate-specific antigen level, pathologic stage, or estimated blood loss between the cell salvage and autologous predonation groups. The preoperative and postoperative hematocrit levels were higher in the cell salvage group (42.7% versus 39.6% and 31.3% versus 27.9%, respectively; P <0.001 for each). The homologous transfusion rates were lower in the cell salvage group (3% versus 14%, P = 0.04). The incidence of progression-free survival (prostate-specific antigen level 0.4 ng/mL or greater) was no different between the groups (P = 0.41). CONCLUSIONS: Intraoperative cell salvage with autotransfusion using leukocyte reduction filters in RRP results in higher perioperative hematocrit levels and low homologous transfusion rates and eliminates the need for autologous predonation. Cell salvage does not appear to be associated with an increased risk of early biochemical progression after RRP.

RESUMEN

PURPOSE: Patients with surgically staged localized prostate cancer treated with external beam radiation therapy were retrospectively analyzed for 15 and 20-year overall and cause specific survival. The need for additional therapy was also evaluated. MATERIALS AND METHODS: We analyzed 145 patients who received external beam radiotherapy after negative staging pelvic lymphadenectomy. Followup data were available for 129 patients. Overall and cause specific survival was calculated with the Kaplan-Meier method. RESULTS: Median followup was 14.9 years. Actuarial overall survival at 15 and 20 years was 45.9% and 24.6%, respectively. Cause specific survival at 15 and 20 years was 64.5% and 37.7% for having all patients dying of unknown causes censored, and 54.4% and 30.1% for those dying of unknown causes categorized as having prostate cancer, respectively. Of the patients who survived 47% were on hormonal therapy. CONCLUSIONS: Longer followup after external beam radiation therapy continues to demonstrate a decrease in cause specific survival. Many patients ultimately require hormonal therapy.

RESUMEN

OBJECTIVE: The outcome of surgery for relief of orchalgia in patients with identifiable intrascrotal pathology is not well defined. We evaluated the success of commonly performed surgical procedure indicated for pain relief in patients with specific intrascrotal lesions. METHODS: Surgical cases performed for relief of painful scrotal pathology were reviewed, including ligation of internal spermatic vein, hydrocelectomy, spermatocelectomy, and orchiopexy for suspected intermittent torsion. Relief of pain as reported to the physician and time for return to full activity were determined. Pain relief was compared to a 50% placebo rate using Fisher's exact test. RESULTS: Eigthy-five of 151 patients (56%) undergoing surgery for pain relief had complete data and adequate follow-up for analysis. Of 40 patients who had ligation of the internal spermatic vein, 30 (75%) were relieved of pain (p = 0.037). All 19 patients with painful hydroceles and 16 of 17 (94%) with spermatoceles were relieved of pain (p < 0.001). Of 9 patients undergoing scrotal orchiopexy for suspected intermittent torsion, 8 (89%) were pain-free (p < 0.001). CONCLUSION: Surgical management of specific intrascrotal lesions is highly effective.

RESUMEN

Owing to azithromycin's prolonged half-life, shorter and shorter dosage regimens are being studied for treatment of respiratory tract infections. Previous studies have concluded that the 3 and 5 day (1.5 g total) regimens not only provide at least equal serum and WBC exposures but also equal efficacy rates. An earlier clinical study using the entire 1.5 g dose at once or the current 3 day regimen in patients with atypical pneumonia noted equal efficacy. Similar trials are currently underway in both adult and paediatric populations. The goal of the present study was to investigate whether there were equal serum and WBC exposures when azithromycin was dosed as the current 3 day regimen or as a single large dose. Equal exposures would help validate future clinical trials of single dose regimens. Twelve healthy volunteers received both azithromycin regimens (1.5 g single dose and 500 mg/day for 3 days) in random order. Serum and WBC samples were collected at baseline and repeatedly for 10 days following the first dose of each regimen. Serum samples were assayed via HPLC (CV% < 10) and WBC samples via liquid chromatography/mass spectrometry (CV% < 10). Data were modelled using noncompartmental methods. Statistics were via ANOVA with significance defined as P < 0.05. All subjects completed both regimens with minimal incidence of adverse effects. Serum data [mean (range)] demonstrated no significant difference in exposure between the two regimens [single 13.1 (3.02-20.6) mg x h/L versus 3 day 11.2 (2.98-24.5) mg x h/L: P = 0.12], although it favoured the shorter regimen. WBC results demonstrated much higher exposures than seen with serum, but no significant difference between the two regimens was identified. These results suggest that a single oral 1.5 g regimen of azithromycin for respiratory tract infections should provide exposure at least equal to currently approved treatment regimens.

RESUMEN

PURPOSE: In patients suspected to have the vertebral, anal, tracheoesophageal, renal, radial, cardiac and limb abnormalities (VACTERL) association we studied the frequency of upper urinary tract anomalies, prevalence of these features, predictability of upper tract pathology and proper screening evaluation. MATERIALS AND METHODS: From 1991 to 1998 we identified 55 patients with the VACTERL association. Upper urinary tract assessment, including initial renal ultrasound and voiding cystourethrography, and followup data were available for 29 boys and 15 girls. Patients were considered to have the VACTERL association when 3 or more organ systems were involved. RESULTS: Average followup was 5.4 years. Upper urinary tract involvement was noted in 41 of the 44 patients (93.2%) and vesicoureteral reflux in 17 (25 renal units). Of the kidneys 21 were hydronephrotic without reflux or obstruction, 10 were solitary, 3 were multicystic dysplastic, 8 were obstructed and only 17 were normal. A total of 27 patients (61%) underwent at least 1 genitourinary procedure, primarily ureteroneocystotomy. All children were alive at the last followup. CONCLUSIONS: The VACTERL association involves multiple serious anomalies. However, these infants generally have a good outcome. Since the upper urinary system is the most common organ system involved, patients should receive prophylactic antibiotics until an initial urological assessment with renal ultrasound and voiding cystourethrography is performed. It is essential for physicians to know that most children with the VACTERL association have urological involvement that requires treatment and long-term management.

RESUMEN

BACKGROUND: TennCare, Tennessee's Medicaid managed care program, was introduced in 1994 with the goals of controlling spending and of improving access to health care. OBJECTIVE: To assess changes in the continuity of enrollment following the implementation of TennCare for 2 groups: infants in the first year of life (defined as persons aged 0-12 months in this study) and children hospitalized with a chronic health condition (defined as persons aged 0-18 years in this study). DESIGN: Retrospective cohort analysis. SETTING AND POPULATION: Infants born during 1992 or 1995 to women enrolled in Medicaid or TennCare and 0- to 18-year-old children enrolled in Medicaid or TennCare who were discharged from a hospital during 1992 or 1995 with a chronic health condition. MAIN OUTCOME MEASURES: For infants, failure to enroll an infant in the first 30 days of life or subsequent gaps in enrollment for 7 days or longer during the first year of life. For children hospitalized with a chronic health condition, any gap in enrollment lasting 7 days or longer by 1 year after discharge from a hospital. RESULTS: There was a reduction in the proportion of infants without continuous enrollment in the first year of life following TennCare (19.4% after vs 25.1% before TennCare; odds ratio, 0.69; 95% confidence interval, 0.67-0.72). Improvements in continuity of enrollment for infants occurred despite an increase in the proportion of infants who were not enrolled in TennCare in the first 30 days of life, even though their mother was enrolled at delivery (14.0% after vs 8.0% before TennCare; odds ratio, 1.86; 95% confidence interval, 1.78-1.96). There was a decrease in the proportion of children hospitalized with a chronic health condition who had subsequent gaps in enrollment by 1 year following discharge from a hospital (14.3% after vs 23.3% before TennCare; odds ratio, 0.52; 95% confidence interval, 0.46-0.59). CONCLUSION: For infants in the first year of life and for children hospitalized with a chronic health condition, implementation of TennCare improved continuity of coverage.

RESUMEN

BACKGROUND: A pilot study was conducted to learn whether an academic medical center's database of patient complaints would reveal particular service units (or clinics) with disproportionate shares of patient complaints, the types of complaints patients have about those units, and the types of personnel about whom the complaints were made. RESULTS: During the seven-year (December 1991-November 1998) study period, Office of Patient Affairs staff recorded 6,419 reports containing 15,631 individual complaints. More than 40% of the reports contained a single complaint. One-third of the reports contained three or more complaints. Complaints were associated with negative perceptions of care and treatment (29%), communication (22%), billing and payment (20%), humaneness of staff (13%), access to staff (9%), and cleanliness or safety of the environment (7%). Complaints were not evenly distributed across the medical center's various units, even when the data were corrected for numbers of patient visits to clinics or bed days in the hospital. The greatest proportion of complaints were associated with physicians. DISCUSSION: Complaint-based report cards may be used in interventions in which peers share the data with unit managers and seek to learn the nature of the problems, if any, that underlie the complaints. Such interventions should influence behavioral and systems changes in some units. SUMMARY AND CONCLUSIONS: Further experience should indicate how different types of complaints lead to different kinds of interventions and improvements in care. Tests of the system are also currently under way in several nonacademic community medical centers.

RESUMEN

STUDY OBJECTIVE: To provide information, which can be used in the formation of guidelines concerning medical facilities and staff on cruise ships, on the descriptive epidemiology of the medical conditions encountered by cruise ship physicians. METHODS: A retrospective descriptive epidemiologic study design was used to evaluate patient physician encounters on cruises originating in a calendar-year period for the 4 ships of a major cruise ship line with cruises originating in the United States. Demographic data regarding sex and age of the passengers on these ships were available for each cruise. We collected information on patient age, sex, chief complaint, diagnoses, treatment, and patient disposition recorded in the patients' medical records in the ships' medical logs. RESULTS: Seven thousand one hundred forty-seven new patient visits occurred in a population of 196,171 passengers and 1,537,298 passenger days; 56.7% of passengers were female, and 60.7% of patients were female; 43.3% of passengers and 39.6% of patients were male. Visits to the ship infirmaries were made for the following reasons: 18.2% of visits were related to injuries, 69.3% were related to medical conditions, and 12.5% were unspecified or other conditions. The most common diagnosis was respiratory tract infection (29.1%); 11% of patients had a serious or potentially life-threatening diagnosis. The most common group of prescription medications prescribed was antibiotics. CONCLUSION: Many different injuries and illnesses occur on board cruise ships. The spectrum is similar in many respects to the patients presenting to emergency departments. Cruise lines must prepare for the initial treatment and stabilization of patients with serious illnesses or injuries with appropriately qualified and equipped medical personnel and establish procedures for disembarkation of patients to facilities capable of handling such conditions.

RESUMEN

Symptomatic urolithiasis is usually treated with narcotic pain management. This leads to the potential for use of its symptoms for personal gain. Historically, the typical presentation of a narcotic-seeking "stone patient" was a history of radiolucent stones and an intravenous contrast allergy. With the increased use of non-contrast-enhanced computed tomography to evaluate patients suspected of having acute urolithiasis, we have seen a change in the strategy of narcotic-seeking patients. We report 2 patients with pelvic calcifications on non-contrast-enhanced computed tomography feigning symptoms of urolithiasis to receive narcotic drugs.

RESUMEN

An infant born at 38 weeks' gestation with ambiguous genitalia had a prenatal 45X karyotype but an enlarged phallus on an ultrasound scan at 31 weeks' gestation. The newborn examination demonstrated penoscrotal hypospadias with chordee and two gonads palpable in the scrotum with a right hydrocele. Ultrasound showed a saccular structure containing debris behind the bladder. The postnatal karyotype was revealed to be 45X/46XY, with a pseudodicentric Y chromosome. Cystoscopy/genitography identified a uterus and a right fallopian tube, which were removed along with a dysgenetic right gonad. Biopsy of the descended left gonad revealed rare germ cells. The final diagnosis was 45X/46XY male pseudohermaphroditism with testicular dysgenesis. One should be aware of possible chromosomal mosaicism and combine the prenatal karyotype with the ultrasound genital findings to formulate an intersex differential diagnosis.
