A rare overlap syndrome between CREST (calcinosis, Raynaud phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia) syndrome and primary biliary cholangitis (PBC) is described as PACK syndrome, an acronym for primary biliary cholangitis, anticentromere antibodies, CREST syndrome, and keratoconjunctivitis sicca. In this retrospective cohort analysis and review, we present fourteen patients who meet diagnostic criteria for PACK syndrome in one of the largest case series of this group. ⋯ CREST syndrome was diagnosed prior to PBC in 58% of our patients and limited pulmonary and renal involvement were observed. This syndrome is rare, but given its insidious development, clinicians should be aware of this potential overlap in CREST-only and PBC-only patients.

Review Case Reports
Raise vigilance against refractory distributive shock due to severe wet beriberi.
Differentiating the type and cause of shock is crucial for intensive care. The rapid aggravation of lactic acidosis in patients often indicates a severe impairment of oxygen uptake in tissues. Herein, we presented a rare case of refractory distributive shock with severe wet beriberi. ⋯ After several turnovers, the medical history of the patient was requested again and finally obtained. Our emergency management team hypothesized that the thiamine-deficient diet caused an aerobic metabolism disorder in the patient. Overall, we aimed to alert clinicians to unusual causes of distributive shock and further discussed the application of thiamine supplementary therapy in critical care.
