Proposal for a 6-step-approach for differential diagnosis of neonatal erythroderma. J Eur Acad Dermatol Venereol 2022; 36:973-986. [PMID: 35238435 PMCID: PMC9310754 DOI: 10.1111/jdv.18043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 12/15/2021] [Accepted: 02/03/2022] [Indexed: 11/28/2022]
Abstract
The broad differential diagnosis of neonatal erythroderma often poses a diagnostic challenge. Mortality of neonatal erythroderma is high due to complications of the erythroderma itself and the occasionally severe and life-threatening underlying disease. Early correct recognition of the underlying cause leads to better treatment and prognosis. Currently, neonatal erythroderma is approached by a case by case basis. The purpose of this scoping review was to develop a diagnostic approach in neonatal erythroderma. After a systematic literature search in Embase (January 1990 - May 2020, 74 cases of neonatal erythroderma were identified, and 50+ diagnoses could be extracted. Main causes were the ichthyoses (40%) and primary immunodeficiencies (35%). Congenital erythroderma was present in 64% (47/74) of the cases, predominantly with congenital ichthyosis (11/11; 100%), Netherton syndrome (12/14, 86%), and Omenn syndrome (11/23, 48%). Time until diagnosis ranged from 102 days to 116 days for cases of non-congenital erythroderma and congenital erythroderma respectively. Among the 74 identified cases a total of 17 patients (23%) died within a mean of 158 days and were related to Omenn syndrome (35%), graft versus host disease (67%), and Netherton syndrome (18%). Disease history and physical examination are summarized in this paper. Age of onset and a collodion membrane can help to narrow the differential diagnoses. Investigations of blood, histology, hair analysis, genetic analysis and clinical imaging are summarized and discussed. A standard blood investigation is proposed and the need for skin biopsies with Lympho-Epithelial Kazal-Type related Inhibitor-staining is highlighted. Overall, this review shows that diagnostic procedures narrow the differential diagnosis in neonatal erythroderma. A 6-step flowchart for the diagnostic approach for neonatal erythroderma during the first month of life is proposed. The approach was made with the support of expert leaders from international multidisciplinary collaborations in the European Reference Network Skin-subthematic group Ichthyosis.

Misdiagnosis trends in patients with hereditary angioedema from the real-world clinical setting. Ann Allergy Asthma Immunol 2017; 117:394-398. [PMID: 27742086 DOI: 10.1016/j.anai.2016.08.014] [Citation(s) in RCA: 42] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2016] [Revised: 08/05/2016] [Accepted: 08/10/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND Hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE) causes swelling in the skin and upper airways and pain in the abdomen because of mucosal swelling. C1-INH-HAE is frequently misdiagnosed, leading to delays in diagnosis, inadequate treatment, and unnecessary procedures. OBJECTIVE To evaluate the history of misdiagnosis in patients participating in the Icatibant Outcome Survey (IOS). METHODS The IOS is an observational study in which safety and effectiveness of icatibant have been evaluated since 2009. As part of the IOS, patients record any misdiagnoses received before being diagnosed as having C1-INH-HAE. RESULTS In January 2016, a total of 418 of 633 IOS patients with C1-INH-HAE type I or II had provided misdiagnosis data. Of these, 185 of 418 (44.3%) received 1 or more prior misdiagnoses. The most common misdiagnoses were allergic angioedema (103 of 185) and appendicitis (50 of 185). A variety of other misdiagnoses were reported, including a substantial number of gastrointestinal disorders (excluding appendicitis). Misdiagnosis rates were similar between males (41.1%) and females (46.5%) and between C1-INH-HAE type I (43.7%) and type II (51.6%). Patients with family members diagnosed as having C1-INH-HAE were significantly less likely to be misdiagnosed than patients without a family history (140 of 366 [41.7%] vs 38 of 58 [65.5%], respectively; P = .001). Patients with a prior misdiagnosis had longer median delay to C1-INH-HAE diagnosis (13.3 years) than patients without (1.7 years; P < .001). CONCLUSION From this large database, approximately 50% of patients with C1-INH-HAE type I or II have previously had their conditions misdiagnosed, most commonly as allergic angioedema or appendicitis. Misdiagnosis results in marked delays in receiving the correct diagnosis, during which time patients cannot access effective, lifesaving treatment. TRIAL REGISTRATION ClinicalTrials.gov: NCT01034969.

Birmingham epidermolysis severity score and vitamin D status are associated with low BMD in children with epidermolysis bullosa. Osteoporos Int 2017; 28:1385-1392.

Abstract
UNLABELLED Bone status impairment represents a complication of generalized forms of epidermolysis bullosa (EB); however, the prevalence and the main determinants of this event in localized forms remain poorly defined. Birmingham epidermolysis bullosa severity (BEBS) score and 25-hydroxyvitamin D levels are strongly associated with low bone mass, suggesting that vitamin D may play a potential beneficial role in bone health. Further longitudinal studies are needed in order to confirm this hypothesis. INTRODUCTION Bone status impairment represents a complication of generalized forms of EB; thus, we aimed to estimate the prevalence of low bone mass, to examine mineralization differences in various EB subtypes and to identify the most important determinants of bone impairment in children with either generalized or localized EB. METHODS An observational study of 20 children (11 males; mean age ± standard deviation, 11.7 ± 3.9 years) with EB was performed. Clinical history, physical examination, laboratory studies, X-ray of the left hand and wrist for bone age, and dual energy X-ray absorptiometry scans of the lumbar spine were obtained. Areal bone mineral density (aBMD Z-scores) and bone mineral apparent density were related to the BEBS score. RESULTS Areal BMD Z-score (mean -1.82 ± 2.33, range, -7.6-1.7) was reduced (<-2 SD) in 8 patients (40%), whereas aBMD Z-score adjusted for bone age was low in 7 patients (35%). BEBS score and 25-hydroxyvitamin D serum levels were the most important elements associated with aBMD (P = 0.0001 and P = 0.016, respectively). A significant correlation between the aBMD Z-score and area of skin damage, insulin-like growth factor-1, C-reactive protein, and sodium serum levels was also found. CONCLUSIONS Low aBMD can be considered a systemic complication of EB, primarily associated with BEBS score and 25-hydroxyvitamin D levels. Therefore, longitudinal evaluation of bone status is ongoing in these patients to define whether vitamin D supplementation would prevent, or at least reduce, bone status impairment.

Abstract
Subarachnoid hemorrhage is the most common cause of cerebral salt wasting syndrome. There are few reports of this condition in infectious meningitis. We describe a patient with hyponatremia and bacterial meningitis. Hyponatremia rapidly improved after administration of sodium chloride. The purpose of this report is to alert clinicians to the fact that hyponatremic patients with central nervous system disease do not necessarily have a syndrome of inappropriate secretion of antidiuretic hormone (SIADH), but may have cerebral salt wasting syndrome. By contrast with SIADH, the treatment requires saline administration.

Abstract
Bone mass is primarily genetically determined, but exogenous factors also play a major role. The prevention of osteoporosis can start from childhood, and optimal achievement of peak bone mass during childhood and adolescence is important in order to minimise future fracture risks. Chronic inflammatory diseases can have a detrimental effect on bone mass, by means of several mechanisms. Different diagnostic methods for detection and monitoring of osteoporosis are in use or under investigation. The role of calcium and vitamin D supplementation for the prevention and treatment of osteoporosis associated with paediatric rheumatic diseases remains to be established. New treatments such as bisphosphonates and calcitonin are now available, although their use in the paediatric age has been limited.

Abstract
INTRODUCTION Hereditary hemochromatosis is inherited as an autosomal recessive trait. It is characterized by increased absorption of dietary iron. The association between pernicious anaemia and hereditary hemochromatosis has never been described. EXEGESIS We report a case of paradoxical association of hereditary hemochromatosis and pernicious anaemia. CONCLUSION It seems that pernicious anaemia may prevent manifestations of hemochromatosis. We suppose that this protective role is due to atrophic body gastritis with iron malabsorption.

Abstract
BACKGROUND Mycobacterium marinum has been recognized for some forty years. It generally occurs after trauma in a patient who manipulates tropical fish living in an aquarium. CASE REPORT We report the case of an exotic fish seller who developed M. marinum nodular lymphangitis after being bitten by one of the fish. DISCUSSION Nodular lesions occurring after trauma in subjects living in France who are in contact with exotic fish suggest the diagnosis of M. marinum. Nodular lymphangitis is seen in about 50% of the cases. Prolonged antibiotic therapy is required. Several antibiotics are effective including minocycline used in our case for 2 months after complete healing of the wound. Surgery is exceptionally required.

Abstract
BACKGROUND The safety and efficacy of sublingual-swallow immunotherapy (SLIT) in rhinitis caused by house-dust mite were evaluated in a double-blind, placebo-controlled study including 75 patients for 24 months. METHODS Patients received either placebo or SLIT with a standardized Dermatophagoides pteronyssinus (D.pt.) - D. farinae (D.f) 50/50 extract. The mean cumulative dose was 90,000 IR, equivalent to 2.2 mg of Der p 1 and 1.7 mg of Der f I. Symptom and medication scores were assessed throughout the study. Exposure to house-dust mite, skin sensitivity, and serum specific IgE and IgG4 were assessed before starting treatment and after 12 and 24 months. RESULTS Seventy-two patients (36 active-36 placebo) were eligible for intent-to-treat analysis. Thirty-six patients dropped out of the study. The number of patients who dropped out due to lack of efficacy was eight out of 37 (21.6%) in the active treatment group compared to 15 out of 38 (39.5%) in the placebo group (chi-square=2.81, P=0.09). Total symptom and medication scores decreased significantly after 12 and 24 months (P<0.05) of treatment in both groups, but no significant difference was observed between the active and placebo groups. After 24 months, the number of patients with high levels of indoor allergenic load decreased significantly in both groups compared to baseline data (P=0.01). Specific IgE (D.pt. and D.f.) increased significantly in the active treatment group after 12 and 24 months, while no change was observed in the placebo group. Specific IgG4 levels were not significantly modified in either group. Two patients in each group reported mild adverse effects. No severe adverse effects were reported. CONCLUSIONS We conclude that SLIT in rhinitis caused by house-dust mite was safe, but there was a lack of consistent clinical benefit compared to placebo, probably due to the impact of the allergen avoidance measures that lowered the allergen burden.

Abstract
A 30-year-old woman developed progressive left sided hemiparesis with intracranial hypertension signs. CT scan and MRI showed a large temporo parietal cystic mass with marked surrounding edema. Surgical excision was performed, and histological analysis revealed an inflammatory granuloma. No disease elsewhere was found and all classical causes of granulomas such as tuberculosis, toxoplasma, fungus infections, inflammatory diseases, lymphomas and cancers were excluded. No treatment was administered and she remained neurologically stable for two years. Afterwards, she developed chronic meningo-encephalitis, hypothalamic-pituitary dysfunction and hydrocephalus requiring decompression. Sarcoidosis was suspected, a steroid therapy was initiated, she gradually improved and a ventricular biopsy confirmed this diagnosis. Nervous system lesions complicate the course of sarcoidosis in 5 to 15% of patients and most commonly involve the cranial and peripheral nerves. CNS involvement is typically meningeal with a predilection for the hypothalamic region. Intracranial mass lesions are rare and their occurrence in the absence of disease elsewhere is still more unusual. Three presentations have been described: an isolated intra parenchymatous mass, multiples nodules, and subdural plaques, that can be mistaken for meningiomas, gliomas or metastases. When systemic manifestations of sarcoidosis are absent, the diagnosis is difficult, and Gd-enhanced MRI is now considered the diagnostic method of choice. However brain biopsy is sometimes necessary. Corticosteroids are the mainstay of therapy. Immunosuppressive agents are also used and brain irradiation has been tried in some refractory cases. Surgical approach may be indicated to establish tissue diagnosis, to perform decompression and to remove brain tumors.

Abstract
OBJECTIVE To determine: (i) the proportion of vesicoureteric reflux (VUR) associated with congenital renal damage and whether it can be severe enough to cause renal impairment from birth: (ii) to evaluate the distribution of males and females affected; and (iii) to describe the course of congenital damage in the first years of life. PATIENTS AND METHODS A total of 108 children (76 male and 32 female, M:F 2.3:1), whose VUR was diagnosed before any infection, were followed from birth for a mean (range) of 4.3 (1-10) years. Renal damage was defined by serum creatinine concentration, creatinine clearance and renal imaging (ultrasonography and renal scintigraphy) performed within the first month of life and periodically thereafter. RESULTS Of the 108 children, 58 had bilateral and 50 unilateral reflux (total number of refluxing units, 166). High-grade VUR (grade > or = 4) was found in 96 (58%) refluxing renal units (RRUs). Males had a prevalence of bilateral severe (> or = grade 4) reflux (M:F 5.2:1), while in those wit unilateral VUR, the M:F ration was 1.5:1. At birth, mild to moderate damage was present in 56 (36%) RRUs and only associated with VUR of grade > or = 3. Bilateral reflux of grade > or = 4 was associated with congenital moderate/severe renal failure in nine neonates (seven males). In infants with grade > or = 4 VUR who underwent surgical correction, VUR resolved in 92% of cases. In infants with VUR of grade > or = 4 followed medically, the reflux spontaneously resolved in 42% and ameliorated in 16% after 18 months. Serial renal scans during the follow-up showed no progression of renal damage. CONCLUSIONS VUR diagnosed at birth on prenatal ultrasonography is associated with congenital damage, with males affected more often than females. The damage involves both kidneys in a consistent proportion and is an important cause of chronic renal impairment from birth. It does not progress in the first years of life if infections are prevented. It is suggested that males with this condition may constitute a major group at risk of developing chronic renal failure in later life.

Abstract
A 49-year-old woman presented with isolated aphasia followed by dementia and ataxia with a duration of 4 years. Histopathologically there was panencephalic involvement, status spongiosus, and kuru-type plaques. Molecular analysis showed heterozygosity at codon 129 in the prion protein (PrP) gene, and type 2 protease-resistant PrP. The comparison between this case and those previously reported suggests that the panencephalopathic variant of Creutzfeldt-Jakob disease (CJD) is an aspecific end-stage condition displayed by most if not all CJD variants in individual patients with an unusually prolonged course.

Abstract
The combination of captopril and indomethacin has been shown to control nephrotic proteinuria in an infant with congenital nephrotic syndrome of the Finnish type. We report the satisfactory control of congenital nephrotic syndrome by enalapril, maintaining normal serum albumin levels without albumin infusions. The haplotype data of our patient were consistent with the diagnosis of a Finnish-type nephrotic syndrome. After 21 months, during which daily infusions of albumin allowed partial control of the symptoms, captopril treatment was started. No adverse effects were noted. Serum creatinine levels remained normal. Within 8 weeks, albumin infusions were completely stopped. After 1 month the treatment was changed to a single dose of enalapril (0.8 mg/kg per day). During the next 15 months, the serum protein concentration was maintained around 6.5-7 g/dl, although proteinuria persisted (0.3-0.5 g/day). Weight and length gain are now satisfactory. We conclude that enalapril may be safely used in infants with severe forms of congenital nephrotic syndrome and might allow the avoidance of aggressive treatments for prolonged periods.

Abstract
INTRODUCTION Cadmium is a carcinogenic substance and bronchial and prostatic cancer may be readily identified as professional diseases. It is also a nephrotoxic substance but renal carcinoma are rarely imputed to this kind of intoxication. CASE REPORT We report the observation of a 59-year-old woman with a long unprotected professional exposure to cadmium. She developed an epidermoid carcinoma of the kidney and later of the lung. Levels of cadmium in blood samples were abnormally high, confirming the existence of a chronic impregnation. CONCLUSION We have judged cadmium to be responsible for her renal disease: the fact of a long unprotected professional exposure, the scarcity of renal epidermoid carcinoma, the well established nephrotoxicity of this substance and the association with other cancers, appear to us as convincing evidence, and the kidney cancer of our patient has been considered a professional disease.

Abstract
A cross sectional survey was set up to study the relation between the prevalence of allergic-type reactions during HIV infection course. For each patient, a standardized interview about recent allergic-type manifestations (RATM), skin prick-tests to six common airborne allergens, IgE serum level were done. Among the 115 included patients, the mean CD4 lymphocyte count (CD4) was 214.7/mm3 (range: 0-1328/mm3). RATM were found in 8.8% of patients with CD4 < 50, in 30% of patients with CD4 between 51 and 200, in 36% of patients with CD4 between 201 and 350 and in 11.5% of patients with CD4 < 350 (p = 0.03). The risk of presenting RATM was 4.8 times (95% confidence interval = 1.7-13.5) higher in patients with CD4 between 51 and 350 than in other patients (p = 0.003). The proportion of positive prick-tests did not significantly vary according to the level of CD4. The increased frequency of RATM in patients with CD4 between 51 and 350/mm3 could be due to an allergic predisposition acquired during the course of HIV infection. The mechanisms explaining the reduced frequency of allergic manifestations when immunodeficiency is profound (CD4 < 50/mm3) remain to be explained.

Abstract
Ten fetuses with hydronephrosis underwent one to seven urine sampling procedures at 23 to 36 weeks' gestation to evaluate renal function. Postnatally, the infants' renal function was assessed by a combination of serum creatinine measurement, ultrasonography and renal scintigraphy. Six infants had pyelo-ureteric junction obstruction, two had megabladder with megaureter, and two had vesico-ureteric reflux. All infants had normal serum creatinine levels at the time of postnatal follow-up, but five of the seven with unilateral involvement had moderate or severe renal damage. Abnormal urinary electrolyte concentrations were found antenatally in only two of them. For the three infants with bilateral hydronephrosis, postnatal evaluation showed moderately or severely damaged kidneys despite prenatal evidence of normal biochemical indexes. Fetal urine electrolyte measurement may be accurate in the diagnosis of renal dysplasia, but its sensitivity is poor in predicting moderate renal dysfunction.

Abstract
A 52 year-old man was hospitalised for acute renal failure with thrombocytopenia and hemolytic anemia without oliguria. A haemolytic-uremic syndrome was diagnosed and prostacyclin infusion was started. Twenty-four hours later, the renal function improved as well as thrombocytopenia and anemia. Recovery occurred after 11 days of treatment. Haemolytic-uremic syndrome treatment is not well codified: plasmaphoresis, fresh frozen plasma, transfusions showed inconstant efficiency and data about prostacycline treatment are rare and often contradictory. Multicentric studies must be started in order to determine the precise benefit of this treatment.

Abstract
Obstructive uropathy causes tubular resistance to aldosterone and severe metabolic imbalance may be precipitated by an episode of pyelonephritis. In the last 3 years we investigated 52 episodes of pyelonephritis (positive urine culture, elevated C reactive protein, fever, elevated neutrophil count) in 50 children between 15 days and 15 months of age. Ultrasonography voiding cystography and renal scintiscan were performed in all cases and i.v. urography in some. A salt-losing syndrome with hyponatremia and hyperkalemia (Na < 125 meq/liter; K > 6.3 meq/liter) was observed in 17 infants < 3 months, accompanied by plasma aldosterone concentration of 5000 to 23,000 pg/ml (normal value, < 1000 pg/ml). All these children had a severe urinary tract (UT) malformation (ureteropelvic junction stenosis in 7 cases, vesicoureteral reflux in 7, posterior urethral valves in 2, double system in 1). Thirteen infants < 3 months, 7 with no urinary tract malformations, did not have electrolyte imbalance. Pyelonephritis was diagnosed in 20 other patients ages 4 to 15 months, including 16 with severe UT malformations; 4 had normal UTs. We conclude that a salt-losing syndrome with tubular resistance to aldosterone can occur during pyelonephritis in young infants with congenital UT malformation, that the risk diminishes considerably or disappears after 3 months of age and that in the absence of UT malformation pyelonephritis does not cause acute sodium loss of clinical relevance.

Abstract
We report two cases of nasosinusal infection caused by Scedosporium apiospermum and involving the nasal fossa in one case and the maxillary sinus in the other. The course of the disease varied according to the patient's immune status. The otherwise healthy patient (case n. 1) was completely cured by surgery, whereas the immunosuppressed patient (case n. 2) had local extension with pseudotumoral symptoms and lysis of the inter-sinusonasal septum; an early surgical treatment combined with local administration of a specific antifungal agent resulted in an apparent cure, but the patient died a few months later. A review of the literature confirms the invasive potential of this fungus which in immunosuppressed patients (by therapeutic immunosuppressants or by a debilitating disease) becomes a dangerous opportunistic organism. Cultures on Sabouraud's medium provide an accurate diagnosis and enable antifungal drugs to be tested, miconazole being the most regularly effective of them. In healthy subjects surgery is the sole treatment of nasal or sinusal lesions, while in all immunocompromised patients it must be combined with an antifungal treatment.

Abstract
Aspirine-sensitive asthma (ASA) is a disease defined only by clinical criteria. It is an intrinsic asthma related to a hypersensitivity to aspirin. The illness is linked to abnormalities in platelet and macrophage arachidonic acid metabolism. We assessed in vitro the platelet chemoluminescence (CL) and lymphocyte proliferative response of ASA patients. We observed that platelets from patients and control do not generate any CL in the presence of aspirin. Concerning the proliferative response of lymphocytes, the in vitro effect of aspirin depends upon the origin of the lymphocytes tested. Thus aspirin clearly enhances the proliferative response of lymphocytes from normal subjects but diminishes the thymidine uptake by lymphocytes from ASA patients. This discrepancy in the in vitro response of lymphocytes from normal subjects and patients might be useful for in vitro diagnosis of ASA.

Abstract
We report the case of a right atrial-ventricular chamber thrombus discovered four years after insertion of a Le Veen shunt for treatment of refractory ascites. A two-dimensional echocardiogram, performed after the discovery of an isolated systolic murmur, demonstrated a "tumorlike" mass seated in both the right atrium and the right ventricle. The mass was surgically removed and histologic examination confirmed that it was a thrombus developed at the tip of the catheter. We propose that two-dimensional echocardiography should be performed periodically for the survey of such intracardiac devices.

Abstract
In a case of hypokalemic periodic paralysis with characteristic alterations of the sarcoplasmic reticulum (SR) in the skeletal muscle, subcellular calcium re-partition, as revealed with the pyroantimonate technique, appears disturbed during paralysis. Pyroantimonate precipitates, normally concentrated in the terminal cisternae of the SR, were localized in the T tubules, whereas the terminal cisternae appeared empty. The increase (about 14%) in muscular calcium during paralysis may result from the accumulation of calcium in the extracellular compartment (T tubules). Defects in calcium uptake and storage by the SR may be involved in the pathogenesis of the periodic paralysis syndrome.
