Hypokalemia is a frequently encountered electrolyte disturbance, particularly among hospitalized patients. It often arises from increased potassium excretion (via the kidney or gastrointestinal tract) or intracellular shifts [1]. Hypokalemic periodic paralysis (HPP) is an uncommon cause of hypokalemia, with the most common reported mutation found in the dihydropyridine-sensitive calcium channel in skeletal muscles (CACNA1S gene) [2]. We present a case of a young woman with HPP associated with a novel mutation in the chloride voltage-gated channel 1 (CLCN1) gene.

The patient, a 32-year-old woman diagnosed with Sjögren's syndrome (SS), according to the 2016 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) criteria, presented with paresthesia of her face and limbs. Extra glandular manifestations of her primary disease included severe Raynaud's phenomenon and chronic interstitial nephritis. There was no family history of neurologic diseases. Neurological examination was notable for symmetrical decreased sensation in the upper limbs distally. The rest of the neurological examination was unremarkable.

Background: Carbapenem-resistant Acinetobacter baumannii (CRAB) is an important cause of nosocomial infections. Active surveillance for CRAB carriage to identify and isolate colonized patients is used to reduce transmission.

Objectives: To assess the rate and risks of clinical infection among CRAB-carrier and non-carrier patients.

Methods: Hospitalized patients from whom CRAB screening-cultures were obtained between January and June 2018 were identified retrospectively. All CRAB-carriers were compared to a convenient sample of non-carriers and were followed to detect development of CRAB clinical infection during admission.

Results: We compared 115 CRAB carriers to 166 non-carriers. The median age in the study group was 76 years (IQR 71–87) vs. 65 years (55–79) in the non-carriers group (P < 0.001). Residence in a nursing facility, debilitated state, and admission to medical wards vs. intensive care units were more frequent among CRAB-carriers (P < 0.001). Mechanically ventilated patients included 51 CRAB carriers (44%) and 102 non-carriers (61%). Clinical infection developed in 49 patients (17%), primarily CRAB pneumonia. Of the CRAB-carriers and non-carriers, 26/115 (23%) and 23/166 (14%), respectively, developed a clinical infection (P = 0.05). One-third of the ventilated patients were infected. Debilitated state and antibiotic treatment during hospitalization were linked to higher infection rates (P = 0.01). Adjusted analysis showed that mechanical ventilation and CRAB colonization were strongly associated with clinical infection (P < 0.05).

Conclusion: The rate of CRAB infection among carriers was high. Mechanical ventilation and CRAB colonization were associated with CRAB clinical infection, primarily pneumonia
