Hormonal and Other Changes in Patients with Hypothalamic Amenorrhea.

In patients with hypothalamic amenorrhea, there are alterations of hormones and other factors that affect the secretion of gonadotropin-releasing hormone (GnRH), including :
# low levels of leptin and
# high levels of both ghrelin and neuropeptide Y (NPY).
β-endorphin, corticotropin-releasing hormone (CRH), dopamine, and γ-aminobutyric acid (GABA) are factors that negatively influence GnRH secretion. Some of these factors may also serve as hunger signals from the peripheral to the central nervous system and as links between nutrition and reproduction.
Hallmark findings in adolescents and young women with hypothalamic amenorrhea include overactivity of the hypothalamic–pituitary–adrenal axis, suppression of the hypothalamic–pituitary–ovarian axis, and alterations in thyroid hormone regulation. FSH denotes follicle-stimulating hormone, LH luteinizing hormone, TSH thyrotropin, and T3 triiodothyronine.

“Cotton Wool” Appearance of Paget's Disease

A 63-year-old man presented with a long-standing history of sinusitis and 3 weeks of frontal headache. The physical examination was unremarkable.
The alkaline phosphatase level was elevated at 434 IU per liter (upper limit of the normal range, 129). The serum calcium level was within normal limits.

Radiography of the skull (Panel A) showed thickening of the outer and inner tables of the cranial bones, widening of the diploë, and a “cotton wool” appearance caused by irregular areas of sclerosis (arrows). Computed tomography of the skull (Panel B) confirmed bony expansion, cortical bone thickening, and irregular areas of sclerosis (arrows). These imaging findings reflect the mixed osteolytic and osteoblastic phases of Paget's disease, resulting in accelerated bone turnover with bone deposition and expansion.
The patient was treated with alendronate, which resulted in improvement in frontal headache.

Practical Paediatric Problems: A Textbook for MRCPCH

The problem based approach of the book presents the reader with a slightly different perspective from that found in the traditional system based textbook. Junior doctors deal with and learn from dealing with children with problems – so this textbook with its alternative approach will be a useful additional source of advice and help to many starting off their careers in paediatrics.

This innovative text, modelled on the current RCPCH syllabus for paediatric training, provides all the information that the senior house officer and specialist registrar in paediatrics will need during training and when preparing for the MRCPCH examination. A series of chapters discussing general principles in paediatric medicine is followed by a section covering the problems associated with the major body systems. Each chapter within this latter section is divided into three elements. Element A covers the background basic science to the particular problems being discussed in the chapter, including basic embryology and anatomy, biology and physiology. A description of the techniques involved in investigation where these will be critical to the diagnoses that follow is also included here; Element B presents the core system problems for the chapter. Tables are provided to summarise the different causes, classifications and differential diagnoses, clinical features, key investigations, therapeutic options and outcomes. Concise supporting text provides more detailed information where appropriate. Selected short case histories are also included to highlight the key issues covered in the chapter. Element C is a concise bibliography, incorporating a short series of key primary papers and review articles and suggestions for further reading. Subjects covered under general principles include developmental paediatrics, behavioural issues and learning difficulties, community paediatrics and clinical pharmacology. Clinical chapters include the respiratory, cardiovascular, endocrine and all other body systems. Haematology, oncology, psychiatry, surgical problems and tropical paediatric medicine are also covered here. All chapters contain up-to-date and appropriate information written by practising paediatricians who are each acknowledged specialists in their own field. Thistextbook will fast become an indispensable guide to the specialty for all trainee paediatricians in preparation for the MRCPCH examination and beyond.
