Use of ketamine in Super Refractory Status Epilepticus: a systematic review.

OBJECTIVE: This review specifically investigates ketamine's role in SRSE management. METHODS: PubMed, EMBASE, and Google Scholar databases were searched from inception to May 1st, 2023, for English-language literature. Inclusion criteria encompassed studies on SRSE in humans of all ages and genders treated with ketamine. RESULTS: In this systematic review encompassing 19 studies with 336 participants, age ranged from 9 months to 86 years. Infections, anoxia, and metabolic issues emerged as the common causes of SRSE, while some cases had unknown origins, termed as NORSE (New Onset RSE) or FIRESs (Febrile Infection-Related Epilepsy Syndrome). Most studies categorized SRSE cases into convulsive (N = 105) and non-convulsive (N = 197). Ketamine was used after failed antiepileptics and anesthetics in 17 studies, while in others, it was a first or second line of treatment. Dosages varied from 0.5 mg/kg (bolus) and 0.2-15 mg/kg/hour (maintenance) in adults and 1-3 mg/kg (bolus) and 0.5-3 mg/kg/hour (maintenance) in pediatrics, lasting one to 30 days. Ketamine was concurrently used with other drugs in 40-100% of cases, most frequently propofol and midazolam. Seizure resolution rate varied from 53.3 to 91% and 40-100% in larger (N = 42-68) and smaller case series (N = 5-20) respectively. Seizure resolution occurred in every case of case report except in one in which the patient died. Burst suppression in EEG was reported in 12 patients from two case series and two case reports. Recurrence was reported in 11 patients from five studies. The reported all-cause mortality varied from 38.8 to 59.5% and 0-36.4% in larger and smaller case series., unrelated directly to ketamine dosage or duration. SIGNIFICANCE: Ketamine demonstrates safety and effectiveness in SRSE, offering advantages over GABAergic drugs by acting on NMDA receptors, providing neuroprotection, and reducing vasopressor requirement.

Antimitochondrial antibody-negative primary biliary cirrhosis with secondary Sjogren syndrome: a case report.

Introduction and importance: Primary biliary cholangitis (PBC) is a rare immune-mediated liver disease characterized by the destruction of intrahepatic bile ducts and a positive antimitochondrial antibody (AMA), which is considered a serological hallmark for the diagnosis. Rarely, AMA can be absent/nondetectable in a few cases and is referred to as 'AMA-negative'. Case presentation: The authors present such an uncommon case of AMA-negative PBC in a 39-year-female with Sjogren's syndrome who presented with fatigue, pruritus, and dry eyes. Clinical discussion: Previously published studies state that approximately only about 5% of patients with PBC are 'AMA-negative'. For patients negative for AMA, the diagnosis has to be based on typical pathological features of this disease. Once a diagnosis of PBC is established, regardless of whether it is positive or negative for AMAs, ursodeoxycholic acid is a widely accepted treatment. Conclusion: The presence/absence of AMAs is associated with similar clinical, biochemical, and histopathological characteristics in PBC. The identification of AMAs alone should not impact the diagnosis or treatment of PBC.

Parasitic mature cystic ovarian teratoma: A rare case of autoimplantation of a twisted dermoid cyst.

Extragonadal parasitic dermoid cysts are rare. Diagnosis of such extragonadal parasitic teratoma is often done intraoperatively during surgical exploration of abdominal mass.

Chest wall mass as a sign of ignored hepatocellular carcinoma in an alcoholic cirrhotic patient: a case report.

Bone metastasis of hepatocellular carcinoma (HCC) is usually seen in the course of advanced intrahepatic HCC. Isolated bone metastasis as an initial manifestation of HCC is uncommon. Case presentation: The authors report a case of a 68-year-old male with a history of chronic alcohol consumption who presented with epigastric pain, abdominal distension, and a hard, tender lump on the right posterolateral aspect of his back. Investigation revealed HCC with isolated metastasis to the posterior thoracic wall. Clinical discussion: HCC usually develops secondary to chronic hepatitis B and C infection in the background of chronic liver disease. Common presenting symptoms of bone metastasis include local pain, neurological manifestations, palpable subcutaneous masses, and pathological fractures. An immunohistochemistry analysis is important to differentiate HCC from non-HCC metastasis in patients without known underlying HCC. Treatment is often directed towards palliative care as the prognosis is poor. Conclusion: An isolated rib mass can be an initial presentation of metastatic HCC. Thus, HCC with bone metastasis should be considered in the differential diagnosis in patients presenting with painful swelling in the thoracic region.

Breakage of an orogastric tube in a critically Ill patient: a case report.

Orogastric and nasogastric tubes are common methods of enteral feeding. Although the methods of tube feeding are simple, these methods are not free of complications. Case presentation: This case report describes a 58-year-old patient with the diagnosis of stroke, in whom there was breakage of an orogastric tube during a prolonged ICU stay. Clinical discussion: Early enteral feeding in patients without any contraindications is associated with improved organ survival and recovery, and decreased incidence of infections, which decreases the ICU stay and improves the overall outcome. Nasogastric and orogastric tubes are the most commonly inserted feeding tubes. Breakage of an orogastric tube is a rare complication that can occur due to manufacturing defects, exposure to a harsh acidic environment, and forceful flushing of an obstructed tube. Conclusions: Timely identification of the broken feeding tube can help the treating clinicians retrieve it easily even with the help of a laryngoscope in selected patients.

Sleeve gastrectomy for multiple gastric perforations in a preterm: A case report.

Neonatal gastric perforation (NGP) is a rare life-threatening condition among preterm infants. NGP can occur secondary to necrotizing enterocolitis, distal obstruction, or as a result of gastric tube insertion. Sleeve gastrectomy can be a possible therapeutic option for multiple neonatal gastric perforations.

Primary dedifferentiated liposarcoma of the breast: A case report.

Primary breast liposarcoma is an extraordinarily rare breast malignancy. Histological subtypes including dedifferentiated are confirmed after a thorough histopathological and immunohistochemistry analysis. Liposarcoma of the breast can mimic other breast lesions. Long-term follow-up is needed due to the risk of local recurrence and delayed dedifferentiation.

Depression, anxiety, and burnout among medical students and residents of a medical school in Nepal: a cross-sectional study.

BACKGROUND: Medical students and residents were found to have suffered from depression, anxiety, and burnout in various studies. However, these entities have not been adequately explored in the context of Nepal. We proposed to determine the prevalence of depression, anxiety, burnout, their associated factors, and identify their predictors in a sample of medical students and residents in a Nepalese medical school. METHODS: It was a cross-sectional study with 651 medical students and residents chosen at random between December 2018 and February 2019. The validated Nepali version of Hospital Anxiety and Depression Scale, the Copenhagen Burnout Inventory, and Medical Students' Stressor Questionnaire were used to assess depression, anxiety, burnout, and stressors respectively. We used univariate and multivariable logistic regression analyses to identify the correlation of predictor variables with depression, anxiety, and burnout. RESULTS: The overall prevalence of burnout (48.8%; 95% CI 44.9-52.7) and anxiety (45.3%; 95% CI 41.4-49.2) was more than that of depression (31%; 95% CI 27.5-34.7). Burnout and depression were more prevalent in residents than in medical students (burnout: 64.5% vs 37.6%, P-value < 0.0001; depression: 33.7% vs 29.1%, P-value 0.21). Whereas, medical students were found more anxious than residents (46.3% versus 43.96%, P-value 0.55). Academic related stressors caused high-grade stress to participants. Multivariable model for depression significantly showed anxiety, personal burnout, and work-related burnout as risk enhancing correlates; satisfaction with academic performance as a protective correlate. Similarly, the multivariate model for anxiety significantly identified female gender, depression, personal burnout, teaching and learning related stressors, and past history of mental illness as risk enhancing correlates; being satisfied with academic performance, getting adequate sleep, and being a second-year resident as protective correlates. The logistic model for burnout significantly showed being a first-year resident, depression, anxiety, and drive and desire related stressors as positive predictors. None of the variables were identified as significant negative predictors of burnout. CONCLUSIONS: A high prevalence of depression, anxiety, and burnout was seen among medical students and residents. Most of them were stressed with academic-related factors. A strong correlation between teaching and learning-related stressors with depression and anxiety may be a call for an efficient and more student-friendly curriculum.
