Cyclic bicytopenia in a patient with shapiro syndrome

Iatrogenic Shapiro syndrome: a case report

OBJECTIVES

Shapiro's syndrome (SS) is a rare condition characterized by spontaneous periodic hypothermia. The underlying pathophysiological mechanisms and etiology of this syndrome remain controversial, and fewer than 100 cases have been reported to date. The objective of this case report is to present a unique iatrogenic case of SS and contribute additional insights into the underlying etiology of this rare disorder.

METHODS

We conducted an analysis of existing medical literature and described a clinical case of SS secondary to a neurosurgical procedure.

RESULTS

To our knowledge, we present the first iatrogenic case of SS in a 53-year-old woman who underwent a partial right parieto-occipital lobectomy in 2003 as a treatment for refractory epilepsy. Several years after the surgical procedure, she began experiencing recurrent episodes of hypothermia. Brain magnetic resonance imaging (MRI) revealed the absence of the splenium of the corpus callosum (CC) and pituitary hyperplasia. After ruling out other potential causes of hypothermia, a diagnosis of SS was made.

DISCUSSION

The most plausible mechanism to explain the recurrent hypothermia associated with SS in our patient is a probable disruption of the pathways involved in thermoregulation through the CC as a consequence of the surgical procedure. This case report provides further insights into the etiology of this rare disorder.

A new perspective of hypothalamic disease: Shapiro's syndrome

Shapiro's syndrome (SS) is characterized by spontaneous periodic hypothermia. It occurs to patients regardless of age or sex. To date, <60 cases have been reported worldwide. Current knowledge of the disease is limited to clinical feature since the pathogenesis and etiology are still controversial. In this review, the clinical characteristics, pathological mechanism, and possible etiology of the syndrome were reviewed to improve the clinical understanding of the disease.

Episodic headache with spontaneous hypothermia reveal Shapiro's syndrome variant with effectiveness of clonidine therapy

BACKGROUND

Episodic headache with spontaneous hypothermia constitute an uncommon association and is not well recognized in the International Classification of Headache Disorders (ICHD-3). Spontaneous periodic hypothermia, also called Shapiro's syndrome, is a rare disease characterized by hypothermia attacks associated or not with hyperhidrosis without any triggering factor.

CASE PRESENTATION

We report a rare case of Shapiro's syndrome variantrevealed by episodes of headache with spontaneous hypothermia witheffectiveness of clonidine therapy in a 76-year-old Parkinson's disease woman.

CONCLUSIONS

In the literature, apart from Shapiro's syndrome, headache withhypothermia seem to occur very rarely. In our case,these symptoms may be considered as a very rare non-motor fluctuation ofParkinson's disease.

Chronic Pancytopenia due to Centrally Mediated Hypothermia in Two Children with Severe Neurological Impairment

We report on recurrent pancytopenia over five years in two children with severe impairment of the central nervous system. Assessment by hematology did not identify an etiology, including bone marrow biopsy in one. Both patients had sustained normalized blood cell counts following interventions to maintain or return to a temperature above 33 °C. Acute cytopenias following medically induced and environmental hypothermia have been reported. Recurrent pancytopenia due to centrally mediated hypothermia in patients with severe neurological impairment is often not recognized, putting such children at risk for unnecessary testing and transfusions. We provide a practical approach to management that is feasible for caregivers in the home setting with suggestions for monitoring.
