Recurrent Impetigo Herpetiformis of Pregnancy Successfully Treated with Acitretin

Impetigo herpetiformis (IH) is an extremely rare pustular dermatosis of pregnancy with typical onset during the second or third trimester of pregnancy and generally rapid resolution after delivery. Recurrent case of IH in subsequent pregnancy tend to earlier onset and greater severity. We report a 33-year-old pregnant woman, with a history of mild IH in the first pregnancy, who presented with generalized lesions at nearly 29 weeks' gestation. Her condition had become worse suddenly at 34 weeks' gestation. She developed fever, small for gestational age, and gait disturbance due to ache in both thighs. So we decided to terminate the pregnancy by repeat cesarean section. After delivery, her skin lesions had worsen rapidly in spite of treatment with corticosteroids. So she was treated with a large dose of acitretin. Three months after her delivery, her skin was returned to original state, except for residual pigmentation. In conclusion, our case indicates that clinicians should be aware of the possibility of sudden deterioration of the maternal lesions and fetal condition associated with IH.

Ischemic Stroke and Cancer: Stroke Severely Impacts Cancer Patients, While Cancer Increases the Number of Strokes

BACKGROUND: Cancer and ischemic stroke are two of the most common causes of death among the elderly, and associations between them have been reported. However, the main pathomechanisms of stroke in cancer patients are not well known, and can only be established based on accurate knowledge of the characteristics of cancer-related strokes. We review herein recent studies concerning the clinical, laboratory, and radiological features of patients with cancer-related stroke. MAIN CONTENTS: This review covers the epidemiology, underlying mechanisms, and acute and preventive treatments for cancer-related stroke. First, the characteristics of stroke (clinical and radiological features) and systemic cancer (type and extent) in patients with cancer-specific stroke are discussed. Second, the role of laboratory tests in the early identification of patients with cancer-specific stroke is discussed. Specifically, serum D-dimer levels (as a marker of a hypercoagulable state) and embolic signals on transcranial Doppler (suggestive of embolic origin) may provide clues regarding changes in the levels of coagulopathy related to cancer and anticoagulation. Finally, strategies for stroke treatment in cancer patients are discussed, emphasizing the importance of preventive strategies (i.e., the use of anticoagulants) over acute revascularization therapy in cancer-related stroke. CONCLUSION: Recent studies have revealed that the characteristics of cancer-related stroke are distinct from those of conventional stroke. Our understanding of the characteristics of cancer-related stroke is essential to the correct management of these patients. The studies presented in this review highlight the importance of a personalized approach in treating stroke patients with cancer.

Long-Term Outcomes of Acute Ischemic Stroke in Patients Aged 80 Years and Older

PURPOSE: Short life expectancy influences decision-making when treating very old patients with acute ischemic stroke (AIS). We investigated mortality and survival duration in very old AIS patients (> or =80 years) who received hospital care. PATIENTS AND METHODS: Mortality data were obtained from medical records, structured telephone inquiries, death certificates from the Korean National Statistical Office, and social security data 5+/-1.9 years after stroke onset. Age, gender, vascular risk factors, and functional outcomes from modified Rankin scales (MRS) at discharge were analyzed as predictors of mortality. RESULTS: Among 134 patients, 92 (68.7%) died. On Kaplan- Meier analysis, duration of survival of patients aged 80-84 years was longer than those aged 85-89 or 90-94 (24+/-6.4, 8+/-7.3, 7+/-2.0 months, respectively, p=0.002). Duration of survival of patients discharged in a state of MRS 0-1 was longer than the remaining groups at 47+/-4.8 months (p<0.001). In Cox proportional hazard analysis, age and MRS at discharge were independent predictors of mortality. CONCLUSION: Long-term outcomes of very old patients with AIS are not uniformly grave, therefore predictors of mortality and estimated duration of survival should be considered during decision- making for treatment.

A Case of Morvan Syndrome

Neuromyotonia, or Isaacs' syndrome, consists of continuous muscle fiber activity caused by hyperexcitability of the peripheral nerves. Rarely, these patients also develop CNS symptoms characterized by confusion, insomnia, hallucinations, and agitation. A rare disease consisting of neuromyotonia, autonomic symptoms, and CNS dysfunction is called Morvan's syndrome. We report a 24-year-old man who presented with insomnia, malaise, anorexia, hyperhidrosis, palpitation and myokymia in both the lower extremities. The pathomechanism of Morvan's syndrome is related to the voltage-gated K+ channel (VGKC) antibodies.
