We report on a 30-year-old woman with premature aging, immunodeficiency, and other abnormalities. She had many manifestations of the Mulvihill-Smith syndrome, a disorder that has been described in 4 sporadic individuals, ranging in age from 4 to 17 years. The common manifestations include short stature, microcephaly, a senile face with an underdeveloped lower half, diminished facial subcutaneous fat, multiple pigmented nevi, sensorineural hearing loss, and a low IgG level. Our patient also had severe mental retardation, brachydactyly, severe T cell dysfunction, and suffered from severe verruca vulgaris and a chronic, active Epstein-Barr virus infection. The fact that her parents were first cousins suggests autosomal recessive inheritance of her disorder. Two alternative possibilities were considered: the disorder in the patient represents the Mulvihill-Smith syndrome with immune deficiency as a sign of its advanced stage, or a hitherto undescribed syndrome.

We report the seventh case of Mulvihill-Smith progeria-like syndrome in a 5-year-old boy with a thin, pinched face, failure to thrive, and cutaneous pigmented nevi. The patient's motor and intellectual development were normal. His immune function tests demonstrate evidence of lymphopenia with no selective loss of a major subpopulation, low immunoglobulin (Ig)G2 and IgG4 subclasses, and an absent in vitro proliferative response to pokeweed mitogen. Chromosomal mitomycin and radiation sensitivity were normal. The skin fibroblast growth in culture was slow, and the fibroblasts appeared morphologically different from normal controls in their size and large number of inclusions. In addition, primary cilia, which normally issue from the centrosome, were absent-a new finding in fibroblasts in this disorder. It remains to be seen if the relative absence of centrosomal cilia in cultured fibroblasts in early passages is a consistent finding in this progeria syndrome.

We report the video-polysomnographic sleep characteristics of a 25-year-old woman with the Mulvihill-Smith syndrome, a rare clinical condition characterized by progeria-like aspect, peculiar multiple pigmented nevi, low stature, and cognitive impairment. Among the various exams, two overnight video-polysomnographic recordings were carried out; moreover, cerebral MRI and molecular analysis of the prion protein gene (PRNP) were also performed. The video-polysomnographic recordings showed the absence of clear sleep episodes but the presence of periods during which the patient had poor contact with the environment, stereotyped afinalistic movements of the upper limbs and hands, irregular or periodic breathing (with central apnea episodes), heart rate arrhythmia, and rapid eye movements. Cerebral MRI showed only diffuse mild enlargement of the cortical sulci and the molecular genetics analysis of the PRNP was normal. Our clinical and neurophysiological study seems to indicate that a particular condition of severe sleep disruption, similar to some extent to that reported in the fatal familial insomnia and in the Morvan fibrillary chorea, which has been indicated as Agrypnia Excitata in recent literature, might be associated with the Mulvihill-Smith syndrome. The inclusion of a detailed study on the sleep characteristics of eventual additional patients will certainly help our understanding of this rare condition.

Mulvihill-Smith syndrome is a rare disease that belongs to progeroid syndromes. This syndrome is characterized by a senile face with an underdeveloped lower half, short stature, microcephaly, multiple pigmented nevi, immunodeficiency, hearing loss, and high-pitched voice. We report anesthetic management of a 27-year-old woman, 138 cm and 27 kg, with this syndrome, who underwent removal of mandibular cyst, partial resection of tongue and keratoplasty. Anesthesia was induced with fentanyl, propofol and vecuronium. There was difficulty in maintaining adequate ventilation with a face mask for children, and we used a mask for infants. Her Cormack grade was rated 3 but her trachea could be intubated assisted by BURP procedure. Anesthesia was maintained with sevoflurane, nitrous oxide and oxygen supplemented with fentanyl. The changes of blood pressure during anesthesia were extraordinary, suggesting the presence of advanced arteriosclerosis. The postoperative course was uneventful, with stable hemodynamics, and the patient was discharged from the hospital on 9th postoperative day. Anesthesia for Mulvihill-Smith syndrome should be performed with caution for the potential risk of difficult airway and unstable hemodynamics.

Mulvihill-Smith syndrome (MSS) is characterized by premature aging, multiple pigmented nevi, decreased facial subcutaneous fat, microcephaly, short stature, mental retardation and recurrent infections, however the adult phenotype of MSS has yet to be delineated. We report a 28-year-old woman with Mulvihill-Smith syndrome, who had a solid pseudopapillary cystic tumor of her pancreas at age 17 years. Her distinctive sleep pattern includes severe insomnia with disappearance of sleep spindles and K-complexes, persisting muscle tone, and loss of slow wave sleep. The clinical and neurophysiological studies are compatible with agrypnia excitata, a sleep disorder attributable to a dysfunction of the thalamo-limbic system. Brain magnetic resonance imaging and single photon emission computed tomography revealed structural and functional deficits in the dorsomedial region of the thalamus and indicated that an alteration in the thalamo-limbic system may underlie the sleep disturbances in MSS. Furthermore, the rapid and severe decline in acquired cognitive function showed the distinct cognitive impairments resembling dementia, including intellectual deficits, memory disorder and executive dysfunction. We posit that an early onset tumor, sleep disorder and cognitive decline are adult manifestations of Mulvihill-Smith syndrome.

Mulvihill-Smith syndrome is a rare progeria-like disorder with characteristic findings including premature aging, short stature, pointed face and multiple melanocytic nevi. A young patient with this syndrome was referred to our department because of a pigmented tumor which was suspected to be a malignant melanoma.
