Insulin resistance Type A and short 5th metacarpals

DIABETIC MEDICINE, Issue 6 2003
Vinod K. Patel
Abstract Background/aims Insulin resistance is associated with a number genetic syndromes and a variety of defects of insulin action. Methods We describe three members of an extended family spanning two generations with insulin resistance Type A and short 5th metacarpals. The proband had secondary amenorrhoea, male pattern hair distribution, acne, hirsutism, deep voice, acanthosis nigricans, polycystic ovaries, diabetes, features of acromegaly, raised creatine kinase and triglyceride levels and short 5th metacarpals. Her growth hormone, adrenal steroid and testosterone levels were normal. The proband's daughter had severe acne, hirsutism, acanthosis nigricans, polycystic ovaries, raised triglyceride, glucose and testosterone level short metacarpals and normal insulin receptor gene. The proband's son had a muscular build, raised creatine kinase, hypertriglyceridaemia and short 5th metacarpals. His fasting insulin levels were normal but pro-insulin was raised. Result/conclusion There are many familial and genetic syndromes associated with insulin resistance. This family was diagnosed as having insulin resistance Type A. This family does not conform entirely to any of the previously described syndromes and a number of family members have the phenotype of short 5th metacarpals, which appears to be associated with the features of insulin resistance Type A.

Clinical and Therapeutic Approach to Childhood Acne: An Update

PEDIATRIC DERMATOLOGY, Issue 4 2009
C. Antoniou M.D., Ph.D.
Childhood acne can be classified in neonatal, infantile, mid-childhood, and prepubertal acne, depending on the age of onset. In this review we will present an update on the clinical approach and therapeutic options when facing prepubertal acne in a child. The use of tetracyclines is contraindicated in children younger than 8 years, and oral isotretinoin is not recommended in children younger than 12 years of age according to the FDA and the European Commission. Nevertheless, there are case reports of 10 patients successfully treated with oral isotretinoin for recalcitrant infantile acne with scarring. Further studies are needed to investigate whether isotretinoin may improve the long-term prognosis of infantile acne, which may be associated with more severe acne in adolescence. [source]

Neutrophilic Dermatoses in Children

PEDIATRIC DERMATOLOGY, Issue 5 2008
David R. Berk M.D.
The neutrophilic dermatoses share similar clinical appearances and associated conditions, including inflammatory bowel disease, malignancies, and medications. Overlap forms of disease demonstrating features of multiple neutrophilic dermatoses may be seen. The manuscript attempts to provide an up-to-date review of (i) classical neutrophilic dermatoses, focusing on distinctive features in children and (ii) neutrophilic dermatoses which may largely be pediatric or genodermatosis-associated (Majeed, SAPHO [synovitis, severe acne, sterile palmoplantar pustulosis, hyperostosis, and osteitis] syndrome, PAPA (pyogenic sterile arthritis, pyoderma gangrenosum, and acne), PFAPA (periodic fever with aphthous stomatitis, pharyngitis, and cervical adenopathy), and other periodic fever syndromes, and congenital erosive and vesicular dermatosis healing with reticulated supple scarring).

Fractional 1320 nm Nd : YAG laser in the treatment of acne vulgaris: a pilot study

PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE, Issue 5 2009

Thirty-five patients with moderate to severe acne were treated with a fractional 1320 nm neodymium : yttrium aluminum garnet (Nd : YAG) laser. These patients received six treatment sessions at a 2-week interval. Inflammatory and non-inflammatory lesions were counted before and after treatment. Fractional 1320 nm Nd : YAG laser therapy was well tolerated, resulting in the reduction of inflammatory lesions by 57% (P<0.05) and the reduction of non-inflammatory lesions by 35% (P<0.05). A significant reduction in the skin sebum level by 30% (P<0.05) was also noted after treatment. [source]

Changes of psychiatric parameters and their relationships by oral isotretinoin in acne patients

THE JOURNAL OF DERMATOLOGY, Issue 5 2009
Bong Jin HAHM
ABSTRACT Oral isotretinoin is a highly effective agent for the treatment of moderate to severe acne, but ever since oral isotretinoin was introduced as a modality for acne, the relationship between oral isotretinoin therapy and psychiatric problems, especially depression, has been controversial. The purposes of this study were to know the acute effects of oral isotretinoin therapy on psychiatric symptoms and to investigate the relationships among them, which have not been reported in the published work. This cohort study included 38 acne patients who started oral isotretinoin therapy. Individual patients were examined before administering oral isotretinoin and 2 and 8 weeks after commencement. Acne severity was graded using the Leeds revised acne grading system. Acute psychiatric effects of oral isotretinoin were assessed using a questionnaire authorized by two psychiatrists. This questionnaire included assessments of acne-related quality of life (Assessment of the Psychological and Social Effects of Acne [APSEA]), depression (Beck's depression inventory [BDI]), anxiety (Beck's anxiety inventory [BAI]) and psychopathology (Symptomchecklist-90-revised [SCL-90-R]). Acne grading and APSEA showed similar change patterns. Both improved after 8 weeks of oral isotretinoin treatment. On the other hand, the severity of depression decreased after 2 weeks of treatment. A significant correlation was found between BDI and APSEA, but no correlation was found between BDI and acne grade. These results indicate that oral isotretinoin therapy alleviates depressive symptoms. Improvements in depression are directly related to acne-related life quality improvements rather than to improvement in acne grade. [source]

Poster 2, Acne fulminans: part of the spectrum of SAPHO

BRITISH JOURNAL OF DERMATOLOGY, Issue 6 2007
S.L. Chua
A 13-year-old boy was admitted to hospital with severe back pain and systemic upset. He had commenced isotretinoin 25 mg (0·5 mg kg,1) daily 17 days previously for severe acne unresponsive to oral erythromycin. Isotretinoin was stopped after 4 days due to severe lower back pain. On admission, he was unable to mobilize and the pain was uncontrolled with oral morphine sulphate. Investigations showed leucocytosis and neutrophilia. Magnetic resonance imaging of the vertebrae showed multiple areas of high signal consistent with an inflammatory process such as osteomyelitis. Oral prednisolone 40 mg daily and ibuprofen controlled the pain within 2 days. Sulfasalazine (1 g twice daily) was commenced 10 days later. The re-introduction of isotretinoin 5 mg daily 12 days after admission precipitated severe back pain, necessitating 3 days of intravenous methylprednisolone. The oral prednisolone dose has been reduced over 6 weeks and stopped. The acne is currently controlled with clindamycin, although there is marked scarring. Acne fulminans is a rare condition characterized by sudden onset of severe acne and systemic features such as fever, leucocytosis and arthralgia.1 Osteomyelitic lesions are a recognized feature. In 1987, the term SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome was proposed to describe a clinical entity with skin, joint and bone manifestations. Associated skin conditions include severe acne, psoriasis and palmoplantar pustulosis. Reported sites of osteoarticular involvement include the anterior chest wall, vertebrae, pelvis and mandible.2 Our patient clearly has acne fulminans and fulfils the criteria for SAPHO syndrome. We believe this condition will be increasingly recognized by dermatologists. References 1 Karvonen S. Acne fulminans: report of clinical findings and treatment of twenty-four patients.

A cerebellar demyelinating lesion following treatment of acne with isotretinoin

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 2 2008
M. Yaman
Summary We report the case of a demyelinating lesion located in the left cerebellar region that developed 3 months after the onset of oral isotretionin treatment. In April 2001, 1 year before admission, the patient underwent cranial magnetic resonance imaging (MRI) because of endocrinological problems. This was found to be completely normal. In January 2002, oral isotretinoin treatment was started to treat severe acne. Three months after the onset of therapy, the patient reported lack of appetite, faintness and tinnitus. Her second cranial MRI scan showed a cerebellar lesion, and oral isotretinoin treatment was stopped (April 2002). One month after the cessation of oral isotretinoin treatment, the lesion became less prominent on the MRI scan, and after 3 months, it had disappeared. Although it is difficult to determine the causal association between the demyelinating cerebellar lesion and isotretinoin treatment, we would like to alert physicians to this possibility, because of the common usage of this drug in daily practice.
