Cool Your Jets Bro

History: Twenty-two year old male basic trainee was brought to the ED after collapsing during a routine ruck march. At mile 8/12, soldier was noted to develop an unsteady gate and had witnessed loss of consciousness. A rectal core temperature was obtained and noted to be >107degreeF. Cooling initiated with ice sheets and EMS was activated. On arrival to the ED, patient demonstrated confusion and persistently elevated core temperatures despite ice sheeting, chilled saline and cold water bladder lavage. Cooling measures were discontinued after patient achieved euthermia in the ED;however, his temperatures subsequently spiked>103degreeF. Given rebound hyperthermia, an endovascular cooling (EVC) device was placed in the right femoral vein and patient was transferred to the ICU. Multiple attempts to place EVC device on standby were unsuccessful with subsequent rebound hyperthermia. Prolonged cooling was required. Physical Exam: VS: HR 121, BP 85/68, RR 22 SpO2 100% RA, Temp 102.4degreeF Gen: young adult male, NAD, shivering, A&Ox2 (person and place only) HEENT: Scleral anicteric, conjunctiva non-injected, moist mucus membranes Neck: Supple, no LAD Chest: CTAB, no wheezes/rales/rhonchi CV: tachycardia, regular rhythm, normal S1, S2 without murmurs, rubs, gallops ABD: NABS, soft/non-distended, no guarding or rebound EXT: No LE edema, tenderness SKIN: blisters with broad erythematous bases on bilateral heels Neuro: CN II-XII grossly intact, 5/5 strength in all extremities. Differential Diagnosis: 216. Septic Shock 217. Hypothalamic Stroke 218. Exertional Heat Stroke (EHS) 219. Neuroleptic Malignant Syndrome 220. Thyroid Storm Test Results: CBC: 18.2>14.5/40.6<167 CMP: 128/3.5 88/1831/2.7<104, AST 264, ALT 80, Ca 8.8 Lactate: 7.1 CK: 11 460 Myoglobin: 18 017 TSH: 3.16 CXR: No acute cardiopulmonary process Blood Cx: negative x2 CSF Cx: Negative COVID/Influenza/EBV: Negative Brain MRI: wnl. Final Diagnosis: Exertional Heat Stroke. Discussion(s): No EVC protocols exist for the management of EHS or rebound/refractory hyperthermia. As a result, the protocol used for this patient was adapted from post-cardiac arrest cooling protocols. It is unclear if this adapted protocol contributed to his delayed cooling and rebound hyperthermia as it was not intended for this patient demographic/ pathophysiology. Furthermore, despite initiating empiric antibiotics upon admission, delayed recognition and tailored therapy for his bilateral ankle cellulitis may have contributed to the difficulty in achieving euthermia. In summary, more research needs to be done to evaluate and develop an EVC protocol for EHS. Outcome(s): Euthermia was achieved and maintained after 36 hours of continuous EVC, at which point it was discontinued. His CK, AST/ALT, creatinine and sodium down-trended after discontinuation of EVC. Patient's antibiotics were transitioned to an oral formulation for treatment of ankle cellulitis and he was prepared for discharge. He was discharged with regular follow-up with the Fort Benning Heat Clinic. Follow-Up: After discharge, patient had regularly scheduled visits with the Fort Benning Heat Clinic. His typical lab markers for exertional heat stroke were regularly monitored. He had continued resolution of his Rhabdomyolysis, acute kidney injury and hyponatremia with typical treatment. Soldier returned to duty after 10 weeks of close monitoring and rehabilitation.

Hyperactive delirium in an 11-year-old boy with juvenile neuronal ceroid lipofuscinosis and a SARS-CoV-2 infection

An 11-year-old boy with juvenile neuronal ceroid lipofuscinosis (JNCL) is admitted because of acute agitation and hallucinations. Upon admission, the patient takes lorazepam, which does not induce the expected rest. A PCR-test had a positive result for SARS-CoV-2. Juvenile neuronal ceroid lipofuscinosis (JNCL) is a rare neurodegenerative disease in children and adolescents. Hallucinations are a known symptom in the course of the disease. In the case discussed in this article, however, the pronounced hallucinations fit within a broader clinical picture of a hyperactive delirium. A delirium is by definition provoked by a physical cause. In the presented case, JNCL was an existing risk factor for a delirium, the SARS-CoV-2 infection and lorazepam were presumably the triggering factors. Recent literature shows that an asymptomatic or mildly symptomatic SARS-CoV-2 infection can also trigger a delirium. Treatment consists of treating the physical cause (if possible), supportive measures for the patient and context, as well as medication. The antipsychotics risperidone and haloperidol are recommended. Within the context of JNCL, cautious initiation of a second-generation antipsychotic, such as risperidone, along with great alertness to possible side effects, such as extrapyramidal symptoms and neuroleptic malignant syndrome, are advised. For the young patient in the discussed case risperidone was started, supplemented with olanzapine as rescue medication. The medication had a good effect and no side effects were observed.

Atypical Neuroleptic Malignant Syndrome in a COVID-19 Intensive Care Unit.

Neuroleptic malignant syndrome (NMS) has been defined as a life-threatening neurologic emergency related to the use of antipsychotic medications. It is most often seen with high-potency (first-generation) antipsychotic medications and may occur after a single dose. There have been conflicting reports in the literature of an atypical NMS (ANMS) presentation, associated with lower-potency agents (second generation) antipsychotic medications. NMS is usually diagnosed with a tetrad of clinical symptoms although none of the tetrads is needed for diagnosis. We report a case of a patient admitted for severe acute syndrome coronavirus 2 (SARS-CoV2) pneumonia who developed probable ANMS. SARS-CoV2 also referred to as coronavirus disease 2019 (COVID-19) added another dimension of complication to patient care as we have, at this time, an incomplete understanding of the pathogenesis. We feel critical care clinicians should maintain broad differentials to clinical findings, during the use of multiple medications and not simply attribute the various presentations to COVID-19.

Creutzfeldt-Jakob disease with neuroleptic malignant syndrome.

Creutzfeldt­Jakob disease (CJD) is a rare rapidly progressive fatal neurodegenerative disease. Neuroleptic malignant syndrome (NMS) is a complication of antipsychotic medications which may be used to treat neuropsychiatric symptoms of CJD. We present a case of a 51­year­ old woman with CJD who developed NMS after being prescribed quetiapine.

A Case of Neuroleptic Malignant Syndrome After COVID-19 Vaccination and Possible Mechanisms of Vaccines in the Formation of This Syndrome

Neuroleptic malignant syndrome is characterized by muscle stiffness, hyperthermia, autonomic dysfunction, elevation in serum creatine phosphokinase, and changes in consciousness, which usually occur due to the side effects of life-threatening neuroleptic and antipsychotic drugs, and it can cause high mortality. A few cases of neuroleptic malignant syndrome associated with coronavirus disease 2019 infection and vaccination have been reported in the literature. Our case presented with epileptic seizure and neuroleptic malignant syndrome signs 10 days after receiving a single dose of the BNT162b2 vaccine when under low-dose olanzapine treatment with a diagnosis of autism and epilepsy. According to the laboratory test, the creatine kinase value was very high, there was hyponatremia, and the iron value was low. The patient died. Our aim in reporting this case is to draw attention to the possibility that coronavirus disease 2019 vaccines may trigger neuroleptic malignant syndrome, which can be a fatal complication in patients taking antipsychotics, albeit very rare among the large vaccinated population.

P.0680 Hypernatremia secondary to kidney injury after long-term lithium therapy during COIVD-19 pandemic

Introduction: As bipolar disorder often requires long-term lithium treatment, assessment of adverse effects is critical. Long-term treatment with lithium induces functional and / or structural disturbances in the kidneys. Nephrogenic diabetes insipidus (NDI) occurs in up to 40% of lithium users and leads to a 2-3 times increased risk of chronic kidney disease. Polyuria-associated fluid imbalances and NDI, increase the risk of hypernatremia. Without appropriate and quick treatments, hypernatremia can easily lead to life-threatening consequences. A major adverse effect, hypernatremia secondary to kidney injury induced by lithium should not be misdiagnosed. We report cases of three patients with mood disorders treated with long-term lithium therapy. They presented to our hospital during the state of emergency declared by the Japanese government in response to curb the coronavirus disease (COVID-19) pandemic. They showed hypernatremia and disturbance of consciousness. All three patients had been taking lithium for more 10 years and had dehydration and / or renal damage on admission. The main cause of clinically significant hypernatremia is not drug-induced kidney injury after long-term lithium treatment, but lithium is one of the most common causes of acquired NDI. Case Report: Case 1 A 65-year-old man with a history of bipolar disorder and presented with polyurea, dehydration, and altered consciousness. He had been on lithium carbonate (800 mg twice daily) for over 20 years. Case 2 A 58-year-old woman with recurrent depressive disorder presented with high fever, drowsiness, spasms, and a highly serum creatine phosphokinase. She was admitted to the emergency department to rule out neuroleptic malignant syndrome. She was prescribed lithium carbonate (800 mg twice daily), but was not fully compliant with the treatment. Case 3 A 72-year-old-woman with bipolar disorder and history of hospitalizations at a mental-health rehabilitation institution presented with disturbance of consciousness and psychomotor retardation. She had been on lithium carbonate (400 mg twice daily) for 16 years. Oral dyskinesia and dysarthria were observed as were high fever and confusion. Of the three patients, one was a COVID-19 patient, while the others were not: however, all of them showed hypernatremia. A cohort study showed that infection, intoxication other than lithium, and dehydration were the main causes of hypernatremia. Lithium intoxications only accounted for 1% of all hypernatremia episodes. Probably the COVID-19 infection may directly cause hypernatremia, and dehydration may indirectly cause hypernatremia owing to a close ward, delirium, and physical restraint because they cannot complain about thirst. The COVID-19 pandemic affects the mental health of patients with bipolar disorder. Amounts of alcohol, soft drinks, and food can potentially trigger symptoms of kidney injury and diabetes. Conclusion: These patients with mood disorders after long-term lithium therapy must be carefully monitored their mental condition, including delirium, their complaints, and laboratory data to avoid overlooking severe conditions.

A case of influenza-associated invasive aspergillosis with cerebral hemorrhage due to infectious vasculopathy.

An invasive aspergillosis (IA) primarily occurs among immunocompromised patients. Recently with an influenzae infection prevalently spreading, influenzae-associated invasive aspergillosis (IAIA) has been reported occasionally. By contrast, neuroleptic malignant syndrome (NMS) occurs rarely in psychiatric patients who are treated with Olanzapine. We report a 43 years old male with psychiatric disorder who had developed IAIA followed by NMS and cerebral hemorrhage as the result of aspergillus invasion to cerebral vessels. He had also super-infection of COVID-19, 13 months later to be saved completely after invasive mechanical respiratory supports. From clinical aspects, we would emphasize that it is of importance to find earlier co-occurrence of IAIA patients with cerebral hemorrhage due to secondary infectious vasculopathy of IA.

Probable haloperidol decanoate-induced fever in an African American with benign ethnic neutropenia: A case report.

We present a case in which a patient developed fever and leukocytosis subsequent to each monthly haloperidol decanoate injection, an adverse reaction that does not meet the diagnostic criteria of neuroleptic malignant syndrome (NMS) or any previously reported adverse reaction for this medication. A patient being treated with haloperidol decanoate for psychosis experienced a fever within 3 days of injection and leukocytosis along with swelling, pain, and a "knot" feeling at the injection site. This recurred after each injection for several months. Muscle rigidity or changes in vital signs other than temperature were not noted. Temperature and injection site reactions resolved with administration of acetaminophen and ibuprofen. The elevation in temperature was discovered as a result of universal twice daily temperature monitoring implemented due to the COVID-19 pandemic. Reports of fever with antipsychotics are typically associated with NMS or heat stroke; the details of this case do not meet the clinical criteria for either. Similar reactions are reported for other antipsychotics, such as clozapine and olanzapine, but not for haloperidol. The recommendation was to discontinue use of the medication due to an unclear mechanism of the reaction.

Neuroleptic Malignant Syndrome After Re-introduction of Atypical Antipsychotics in a COVID-19 Patient.

We present a case of neuroleptic malignant syndrome (NMS) in a 46-year-old white female from a state psychiatric hospital who also tested positive for coronavirus-2019 (COVID-19) (severe acute respiratory syndrome coronavirus, SARS-CoV-2) infection after re-introduction of her home antipsychotics medication. She presented with confusion and altered mental status likely secondary to delirium from COVID-19 infection. Clozapine and risperidone were initially held on admission and restarted after continuing agitation on day two. She began to have increased restlessness with rising creatinine kinase (CK) levels, peaking on day seven with sudden fever, hypertension, and tachycardia. The diagnosis of NMS was confirmed, antipsychotic medication was held, and appropriate treatment was administered. The mechanism explaining the occurrence of NMS in COVID-19 patients is still unclear, but COVID-19 infection may be a risk factor for this presentation. The mechanism of SARS-CoV-2 as a risk factor for NMS is still uncertain and needs to be investigated further. However, if their infection status is known, patients should be given neuroleptics with caution and carefully considered for the development of this rare condition.

Neuroleptic malignant syndrome in patients with COVID-19.

We report the first two cases of Coronavirus Disease 2019 (COVID-19) who were receiving intensive care including favipiravir, and were clinically diagnosed with neuroleptic malignant syndrome (NMS) to focus attention on NMS in COVID-19 management. Case 1: A 46-year-old-man with acute respiratory distress syndrome (ARDS) caused by COVID-19 infection was being administered favipiravir. Fentanyl, propofol, and rocuronium were also given. On day 3, midazolam administration was initiated for deep sedation. On day 5, his high body temperature increased to 41.2 °C, creatine kinase level elevated, and he developed tachycardia, tachypnea, altered consciousness, and diaphoresis. NMS was suspected, and supportive therapy was initiated. High-grade fever persisted for 4 days and subsided on day 9. Case 2: A 44-year-old-man with ARDS caused by COVID-19 infection was being treated with favipiravir. On day 5, risperidone was started for delirium. On day 7, his body temperature suddenly increased to 40.8 °C, his CK level elevated, and he developed tachycardia, tachypnea, altered consciousness, and diaphoresis. NMS diagnosis was confirmed, and both, favipiravir and risperidone were discontinued on day 8. On the same day, his CK levels decreased, and his body temperature normalized on day 9. Patients with COVID-19 infection frequently require deep sedation and develop delirium; therefore, more attention should be paid to the development of NMS in patients who are being administered such causative agents. The mechanism underlying the occurrence of NMS in COVID-19 patients treated with favipiravir remains unknown. Therefore, careful consideration of NMS development is necessary in the management of COVID-19 patients.
