Describing the natural history of clinical, biochemical and radiological outcomes of children with familial partial lipodystrophy type 2 (FPLD2) from the United Kingdom: A retrospective case series.

CONTEXT: Familial partial lipodystrophy type 2 (FPLD2) results from autosomal dominant mutations in the LMNA gene, causing lack of subcutaneous fat deposition and excess ectopic fat accumulation, leading to metabolic complications and reduced life expectancy. The rarity of the condition means that the natural history of FPLD2 throughout childhood is not well understood. We report outcomes in a cohort of 12 (5M) children with a genetic diagnosis of FPLD2, under the care of the UK National Severe Insulin Resistance Service (NSIRS) which offers multidisciplinary input including dietetic, in addition to screening for comorbidities. OBJECTIVE: To describe the natural history of clinical, biochemical and radiological outcomes of children with FPLD2. DESIGN: A retrospective case note review of children with a genetic diagnosis of FPLD2 who had been seen in the paediatric NSIRS was performed. PATIENTS: Twelve (5M) individuals diagnosed with FPLD2 via genetic testing before age 18 and who attended the NSIRS clinic were included. MEASUREMENTS: Relationships between metabolic variables (HbA1c, triglycerides, fasting insulin, fasting glucose and alanine transaminase [ALT]) across time, from first visit to most recent, were explored using a multivariate model, adjusted for age and gender. The age of development of comorbidities was recorded. RESULTS: Three patients (all female) developed diabetes between 12 and 19 years and were treated with Metformin. One female has hypertrophic cardiomyopathy and four (1M) patients developed mild hepatic steatosis at a median [range] age of 14(12-15) years. Three (1M) patients reported mental health problems related to lipodystrophy. There was no relationship between biochemical results and age. Patients with diabetes had higher concentrations of ALT than patients who did not have diabetes, adjusted for age, gender and body mass index standard deviation scores. CONCLUSIONS: Despite dietetic input, some patients, more commonly females, developed comorbidities after the age of 10. The absence of relationships between biochemical results and age likely reflects a small cohort size. We propose that, while clinical review and dietetic support are beneficial for children with FPLD2, formal screening for comorbidities before age 10 may not be of benefit. Clinical input from an multidisciplinary team including dietician, psychologist and clinician should be offered after diagnosis.

Early Postnatal Use of Glibenclamide in Permanent Neonatal Diabetes Secondary to Antenatally Diagnosed KJCN11 Mutation.

INTRODUCTION: Heterozygous activating mutations in KCNJ11 cause both permanent and transient neonatal diabetes. A minority of patients also have neurological features. Early genetic diagnosis has important therapeutic implications as treatment with sulfonylurea provides good metabolic control and exerts a protective effect on neuromuscular function. CASE PRESENTATION: A term female infant with normal birth weight (2.73 kg, z-score: -1.69) was admitted to the Neonatal Unit at Addenbrookes Hospital. She had been antenatally diagnosed with KCNJ11 mutation-R201C inherited from her glibenclamide-treated mother who continued sulfonylurea treatment throughout pregnancy. A continuous glucose-monitoring system inserted at 20 h of age showed progressive rise of blood glucose concentrations, prompting treatment with glibenclamide on day 2 of life. Initial attempts to treat with an extemporaneous solution of glibenclamide (starting dose 0.2 mg/kg/day) resulted in inconsistent response and significant hypoglycaemia and hyperglycaemia. A licenced liquid formulation of glibenclamide (AMGLIDIA) at a starting dose of 0.05 mg/kg/day was used with stabilization of blood glucose profile within 24 h. Other than a mild transient elevation in transaminase, treatment was well tolerated. At most recent review (age 12 months), the patient remains well with age-appropriate neurodevelopment. Overall glucose control is reasonable with estimated HbA1c of 7.6% (59.9 mmol/mol). CONCLUSION: Early postnatal glibenclamide treatment of insulin-naive patients with KATP-dependent neonatal diabetes is safe, provides good metabolic control, and has a potential protective effect on neurological function. The formulation of the medicine needs to be carefully considered in the context of the very small doses required in this age group.

Diabetic ketoacidosis with severe hypokalemia and persistent hypernatremia in an adolescent girl with COVID-19 infection.

We report a case of new-onset type 1 diabetes in a girl presenting with severe diabetic ketoacidosis, complicated by profound hypokalemia and hypernatremia. We describe the clinical course, management challenges, and the potential role of the concomitant COVID-19 infection in the complexity of this case.

Gonadotrophin-independent Precocious Puberty Secondary to an Estrogen Secreting Adrenal Tumor.

BACKGROUND: Adrenal masses are rare in children and most commonly present with clinical features of virilization in the absence of activation of the pituitary axis-gonadotrophin-independent precocious puberty. OBSERVATIONS: We report an unusual case of a 7-year-old girl who presented with clinical signs suggestive of exposure to both androgens and estrogens. Imaging revealed a left-sided adrenal mass with no evidence of metastasis. She underwent successful laparoscopic unilateral adrenalectomy. Histology confirmed an adrenal adenoma. CONCLUSION: We conclude that adrenocortical tumors should be considered in children presenting with gonadotrophin-independent precocious puberty and raised estrogens.

Adolescent and Young Adult Cancer Placements: Developing Complex Clinical Communication Skills of Medical Students.

Purpose: Following implementation of a student selected module in adolescent and young adult cancer care for medical students, we sought to explore their experiences of the specialty. Methods: We undertook a focus group of five medical students all in their fourth to sixth year of study. Transcripts were transcribed verbatim and analyzed thematically. Results: We identified six key themes repeatedly elicited during the focus group; these were specialized and holistic care, patient's perspective, connectedness and professional boundaries, triadic communication, emotional impacts, and professional development and support. Conclusion: Early exposure to this specialty is positive for students and the model could be replicated elsewhere.

Safe and effective use of a hybrid closed-loop system from diagnosis in children under 18 months with type 1 diabetes.

The management of type 1 diabetes in infancy presents significant challenges. Hybrid closed loop systems have been shown to be effective in a research setting and are now available for clinical use. There are relatively little reported data regarding their safety and efficacy in a real world clinical setting. We report two cases of very young children diagnosed with type 1 diabetes at ages 18 (Case 1) and 7 months (Case 2), who were commenced on hybrid closed-loop insulin delivery using the CamAPS FX™ system from diagnosis. At diagnosis, total daily dose (TDD) was 6 and 3.3 units for Case 1 and 2, respectively. Closed loop was started during the inpatient stay and weekly follow up was provided via video call on discharge. Seven months from diagnosis, Case 1 has an HbA1C of 49 mmol/mol, 61% time in range (TIR, 3.9-10 mmol/L) with 2% time in hypoglycemia (<3.9 mmol/L) with no incidents of very low blood glucose (BG; <3 mmol/L, 54 mg/dL) over 6 months. Given the extremely small TDD of insulin in Case 2, we elected to use diluted insulin (insulin aspart injection, NovoLog, Novo Nordisk Inc., Plainsboro, NJ, Diluting Medium for NovoLog®). Six months from diagnosis, the estimated HbA1c is 50 mmol/mol, TIR 76% with 1% hypoglycemia and no incidents of very low BG (<3 mmol/L, 54 mg/dL) over 6 months. We conclude that the use hybrid closed-loop can be safe and effective from diagnosis in children under 2 years of age with type 1 diabetes.

Student Stories: Microaggressions in Communication Sciences and Disorders.

Purpose Microaggressions and how they affect underrepresented college students have been frequently documented. However, there is a lack of literature on the experiences of underrepresented communication sciences and disorders (CSD) students. The purpose of this study is to understand how underrepresented post baccalaureate, undergraduate, and graduate students in CSD experience microaggressions in their academic programs. Method A 19-item electronic survey was developed by American Speech-Language-Hearing Association's Multicultural Issues Board and distributed via multiple online platforms. A diverse group of 155 underrepresented CSD students completed the survey. A multistage qualitative thematic analysis was used to analyze students' experiences. Results Students (64.51%) who completed the survey have experienced microaggressions in their academic programs. Prominent themes of students' descriptions of microaggressions included feelings of otherness, damaging generalization, maltreatment from faculty, and maltreatment from peers. Students reported various responses to microaggressions including identity management strategies, disengaging, and working hard to exceed expectations and to prove themselves. Conclusions This study illustrates the ways that underrepresented CSD students experience symbolic violence from clients, peers, and faculty. It has implications for the need to cultivate more inclusive learning and social environments in CSD programs. Further research is needed to explore the ramifications of microaggressions and ways to effectively reduce and eventually eradicate them.

Clinical utility of circulating miR-371a-3p for the management of patients with intracranial malignant germ cell tumors.

BACKGROUND: The current biomarkers alpha-fetoprotein (AFP) and human chorionic gonadotropin (HCG) have limited sensitivity/specificity for diagnosing malignant germ cell tumors (GCTs) and "marker-negative" patients require histological confirmation for diagnosis. However, GCTs at intracranial sites are surgically relatively inaccessible and biopsy carries risks. MicroRNAs from the miR-371~373 and miR-302/367 clusters are over-expressed in all malignant GCTs and, in particular, miR-371a-3p shows elevated serum levels at diagnosis for testicular disease. METHODS: Using our robust preamplified qRT-PCR methodology, we quantified miR-371a-3p levels in serum and cerebrospinal fluid (CSF) in a series of 4 representative clinical cases, 3 with intracranial malignant GCT and 1 with Langerhans cell histiocytosis (LCH), compared with appropriate control cases. RESULTS: Serum and/or CSF miR-371a-3p levels distinguished those with intracranial malignant GCTs from LCH and, if known in real time, could have helped clinical management. The benefits would have included (1) the only confirmatory evidence of an intracranial malignant GCT in 1 case, supporting clinical decision making; (2) early detection of intracranial malignant GCT in another, where an elevated CSF miR-371a-3p level preceded the histologically confirmed diagnosis by 2 years; and (3) confirmation of an intracranial malignant GCT relapse with an elevated serum miR-371a-3p level, where serum and CSF AFP and HCG levels were below thresholds for such a diagnosis. CONCLUSIONS: This series highlights the potential for microRNA quantification to assist the noninvasive diagnosis, prognostication, and management for patients with intracranial malignant GCTs. Serum and CSF should be collected routinely as part of future studies to facilitate the extension of these findings to larger patient cohorts.

Unique Primary Care Needs of Transgender and Gender Non-Binary People.

It is important for the practicing primary care provider to become familiar with the unique health care needs for people who identify as transgender men, transgender women, and non-binary people, who are all within the scope of practice of a general obstetrician-gynecologist and other primary care providers. A review of the unique health needs and essential terminology is presented. This knowledge is a basic foundation to develop a welcoming and inclusive practice for people who are gender nonconforming. This fund of knowledge is essential the practicing primary care providers and support staff.

Subcutaneous Fat Necrosis of the Neonate with a Delayed Second Eruption.

Subcutaneous fat necrosis (SCFN) of the neonate is a rare panniculitis of early life that occurs in association with gestational diabetes and preeclampsia, as well as perinatal asphyxia, hypothermia, and trauma. A characteristic feature of this condition is its self-limiting and monophasic nature. We report a highly unusual case of delayed SCFN in a male neonate involving an anatomically discrete eruption, reminiscent of erythema nodosum, occurring many weeks after his original eruption had resolved.

Pros and cons of GnRHa treatment for early puberty in girls.

The timing of puberty has considerable biological, psychosocial and long-term health implications. Secular trends in age at pubertal development, the effects of obesity and the potential effects of environmental endocrine disruptors challenge the standard definitions of precocious puberty and the indications for intervention with gonadotropin-releasing hormone agonists (GnRHa) in girls with precocious puberty. GnRHa therapy is effective in improving adult height in patients who present with classic central precocious puberty (at <8 years old), without causing adverse effects on body composition, BMD and reproductive function. However, its benefits in patients with atypical forms of early puberty not driven by luteinising hormone are not well defined. The role of GnRHa in these patients and the potential benefits in terms of later growth, psychosocial functioning and long-term risk of adult diseases that are associated with early menarche, such as breast cancer and the metabolic syndrome, have not been established.

Non-irradiated female survivors of childhood acute lymphoblastic leukaemia are at risk of long-term increases in weight and body mass index.

We report long-term, including final height, auxological data from our retrospective study of non-irradiated survivors of childhood acute lymphoblastic leukaemia (ALL). Body mass index (BMI) standard deviation score (SDS) increases in females, due to increased weight-SDS, persisted to final height, with probable adverse long-term health outcomes. In contrast, males demonstrated increased BMI-SDS in follow-up, due to reduced height-SDS, not increased weight-SDS, but such changes had resolved by final height. Childhood ALL survivors, particularly females, are therefore at potential increased risk of developing the metabolic syndrome during follow-up. We recommend that strategies to minimize weight gain should be implemented during ALL treatment.

Polycystic ovarian syndrome during puberty and adolescence.

PCOS has reasonably well defined clinical, biochemical and radiological features in adult women, but in the adolescent population, some of these features may overlap with normal puberty leading to difficulties in making a diagnosis. In addition, the rising prevalence of obesity in the paediatric population may compound insulin resistance in girls predisposed to ovarian hyperandrogenism leading to younger age of presentation and more severe phenotype. It is important to distinguish between normal puberty and true ovarian hyperandrogenism, as well as excluding other causes of androgen excess such as adrenal tumours or non classical congenital adrenal hyperplasia. The long term co-morbidities associated with ovarian hyperandrogenism presenting during adolescence are not well defined but there is likely to be increased cardiovascular risk. There are little data on intervention in the adolescent population and studies in adult women often focus on ovulation and fertility which are less of a concern to adolescents. Current options include insulin sensitisation with metformin, anti androgens, or the oral contraceptive pill, with each girl being treated on an individual basis. There is a requirement for establishment of normative data in adolescence, in conjunction with physiological phenotyping in order to elucidate potential mechanisms thus informing potential intervention.

Premature adrenarche.

Premature adrenarche refers to the presence of secondary sexual hair in girls younger than 8 years old and boys younger than 9 years old. It is a relatively common presentation to paediatricians and is more frequent in girls than boys. It is a benign diagnosis, but other causes of androgen excess such as congenital adrenal hyperplasia or adrenal tumours should be excluded first. In conjunction with history and clinical examination, first line investigations should include determination of serum androgen concentrations, along with bone age, proceeding to synacthen stimulation test (for 17OHP levels) and adrenal ultrasound if indicated. The phenotype of premature adrenarche varies considerably between populations but may be associated with low birth weight, insulin resistance, adverse cardio-metabolic risk and progression to polycystic ovarian syndrome in some populations. In the majority of cases, no specific treatment is recommended, but where there is a history of low birth weight, with associated insulin resistance, intervention with the insulin sensitising agent metformin may be considered on a case by case basis.

What is the best management strategy for patients with severe insulin resistance?

Management of severe insulin resistance (IR) is a major clinical challenge in many patients with obesity or lipodystrophy, and also in rarer patients with proven or suspected genetic defects in the insulin receptor or downstream signalling. The latter group can present at any time between birth and early adult life, with a variable clinical course broadly correlated with the severity of IR. Primary insulin signalling defects are usually associated with poor weight gain rather than obesity. Initially, extreme hyperinsulinaemia produces ovarian enlargement and hyperandrogenism in women, and often fasting or postprandial hypoglycaemia. However, any hypoglycaemia gradually evolves into insulin-resistant hyperglycaemia when beta cell function declines. Optimal management of these complex disorders depends on early diagnosis and appropriate targeting of both high and low glucose levels. In newborns, continuous nasogastric feeding may reduce harmful glycaemic fluctuations, and in older patients, acarbose may mitigate postprandial hypoglycaemia. Insulin sensitization, initially with metformin but later with trials of additional agents such as thiazolidinediones, is the mainstay of early therapy, but insulin replacement, eventually with very high doses, is required once diabetes has supervened. Preliminary data suggest that rhIGF-1 can improve survival in infants with the most severe insulin receptor defects and also improve beta cell function in older patients with milder receptoropathies. The utility of newer therapies such as glucagon-like peptide-1 agonists and dipeptidyl peptidase-IV inhibitors remains untested in this condition. Thus, management of these patients remains largely empirical, and there is a pressing need to collate data centrally to optimize treatment algorithms.

Risk factors for obesity in childhood survivors of suprasellar brain tumours: a retrospective study.

AIM: To characterize postdiagnosis changes in body mass index (BMI) among childhood survivors of suprasellar brain tumours, and to determine the risk factors associated with obesity. METHODS: We conducted a retrospective analysis of 46 children (16 boys and 30 girls) with median (IQR) age of 7.49 (3.47-11.59) years at tumour diagnosis, and followed up for 3.93 (1.68-7.27) years. Survival analyses were used to identify risks of developing obesity. RESULTS: There were no sex differences in age at tumour diagnosis, duration of follow-up, tumour types, endocrinopathies, treatment modalities or baseline BMI SDS. In the first year after tumour diagnosis, ΔBMI SDS (median; IQR) was greater in girls (1.32; 0.07-2.08) than in boys (0.48; -0.40 to 0.89) (p = 0.01). At diagnosis, 3/46 children (6%) were obese; this increased to 20/46 (43%) by last follow-up (p < 0.001) and was more common in girls (17/30; 57%) than in boys (3/16; 19%). Female gender (hazard ratio 5.0, 95% CI 1.2-21.7; p = 0.04) and greater than average baseline BMI (hazard ratio 4.7, 95% CI 1.1-20.8; p = 0.02) were risk factors for subsequent obesity. CONCLUSION: Accurate prediction of obesity risk is important and would allow early targeted intervention in high-risk patients.

Treatment with recombinant human insulin-like growth factor (rhIGF)-I/rhIGF binding protein-3 complex improves metabolic control in subjects with severe insulin resistance.

OBJECTIVE: Diabetes in the context of severe insulin resistance (SIR) presents a major therapeutic challenge because conventional therapies including insulin and insulin sensitizers often fail to achieve adequate metabolic control. Adjunctive therapy with recombinant human IGF-I (rhIGF-I)/recombinant human IGF binding protein-3 (rhIGFBP-3) has been shown to improve insulin sensitivity in both type 1 and type 2 diabetes and may have a role in the treatment of SIR. We report clinical and physiological outcomes after adjunctive therapy with rhIGF-I/rhIGFBP-3 in five subjects with SIR. RESEARCH DESIGN AND METHODS: Five females (median age, 17 yr; range, 5-37) with SIR (two with pathogenic insulin receptor mutations) were treated with 0.5-2.0 mg/kg rhIGF-I/rhIGFBP-3 using a 16-wk dose escalation protocol. Glycosylated hemoglobin was recorded monthly. At baseline and end of treatment all patients were evaluated using continuous glucose monitoring sensing and admitted for overnight GH profiling and insulin-modified stable-label iv glucose tolerance test. Changes in body composition were assessed using dual-energy x-ray absorptiometry and magnetic resonance imaging. RESULTS: Treatment with rhIGF-I/rhIGFBP-3 was well tolerated, and all subjects reported clinical improvements with reduction in acanthosis nigricans. Glycosylated hemoglobin was reduced (8.5% pretreatment to 7.1%; P < 0.03) with a trend toward reduction in mean continuous glucose monitoring sensing glucose (10.7 vs. 8.5 mmol/liter; P = 0.08). Effects of treatment on other biochemical measures were variable, but there was a trend toward improved C-peptide responses during the iv glucose tolerance test. CONCLUSIONS: rhIGF-I/rhIGFBP-3 is well tolerated and clinically effective in subjects with SIR.

Effects of growth hormone and free fatty acids on insulin sensitivity in patients with type 1 diabetes.

CONTEXT: Because GH stimulates lipolysis, an increase in circulating free fatty acid levels, as opposed to a direct effect of high GH levels, could underlie the development of insulin resistance in type 1 diabetes (T1D). Our aim was to explore the relative contributions of GH and free fatty acids to the development of insulin resistance in patients with T1D. PATIENTS: Seven (four females, three males) nonobese patients with T1D aged 21-30 yr were studied on four occasions in random order. On each visit, overnight endogenous GH production was suppressed by octreotide. Three 1-h pulses of recombinant human GH (rhGH) or placebo were administered on two visits each. Acipimox, an antilipolytic drug, or a placebo were ingested every 4 h on two visits each. Stable glucose and glycerol isotopes were used to assess glucose and glycerol turnover. The overnight protocol was concluded by a two-step hyperinsulinemic euglycemic clamp on each visit. MAIN OUTCOME: rhGH administration led to increases in the insulin infusion rate required to maintain euglycemia overnight (P = 0.008), elevated basal endogenous glucose production (P = 0.007), decreased basal peripheral glucose uptake (P = 0.03), and reduced glucose uptake during step 1 of the clamp (P < 0.0001). Coadministration of rhGH and acipimox reversed these effects and suppression of lipolysis in the absence of GH replacement led to further increases in insulin sensitivity. RESULTS: GH pulses were associated with an increase in endogenous glucose production and decreased rates of peripheral glucose uptake, which was entirely reversed by acipimox. Therefore, GH-driven decreases in insulin sensitivity are mainly determined by the effect of GH on lipolysis.

Common gynecologic infections.

Many women seek care for vulvar, vaginal, or pelvic complaints. Primary care providers should possess a solid understanding of the differential diagnosis and treatment of gynecologic infections. Many infections in the reproductive tract are sexually transmitted, whereas other common infections are attributable to an overgrowth of the normally present bacteria or yeast in the vagina. Presenting symptoms and signs are helpful in determining the source of infection, but often a battery of tests must be performed to make a definitive diagnosis.

Intramyocellular lipid levels are associated with peripheral, but not hepatic, insulin sensitivity in normal healthy subjects.

Increased levels of IMCL (intramyocellular lipid) have been shown to be associated with reduced steady-state glucose infusion rates during a hyperinsulinaemic-euglycaemic clamp (M-value). The aim of the present study was to explore how IMCL levels relate to the insulin-mediated suppression of endogenous glucose production [hepatic SI (insulin sensitivity)] and increase in glucose disposal (peripheral SI). In the present study, 11 healthy young adults (7 male, 4 female; aged 21-31 years) undertook, in random order, an hyperinsulinaemic-euglycaemic clamp combined with stable glucose isotope enrichment to measure peripheral and hepatic SI, a 1H-MRS (proton-magnetic resonance spectroscopy) scan to determine IMCL levels and a DXA (dual-energy X-ray absorptiometry) scan to assess body composition. IMCL levels (range, 3.2-10.7) were associated with whole-body fat mass (r=0.787, P=0.004), fat mass corrected for height (r=0.822, P=0.002) and percentage of central fat mass (r=0.694, P=0.02), but were not related to whole-body FFM (fat-free mass; r=-0.472, P=0.1). IMCL levels correlated closely with the M-value (r=-0.727, P=0.01) and FFM-corrected peripheral SI (r=-0.675, P=0.02), but were not related to hepatic SI adjusted for body weight (r=0.08, P=0.8). The results of the present study suggest that IMCL accumulation may be a sensitive marker for attenuations in peripheral, but not hepatic, SI in normal populations. Given the close relationship of IMCL levels to whole-body and central abdominal fat mass, relative increases in the flux of lipids from adipose tissue to the intramyocellular compartment may be an integral part of the mechanisms underlying reductions in SI.
