Severe Metabolic Acidosis: A Case of Triple Hit with Ketogenic Diet, Vinegar, and Metformin in an Obese Patient.

Obesity is an epidemic with high burden of disease. It is directly proportional to increased risk of morbidity and mortality. Ketogenic diet and herbal supplements have recently gained popularity amongst patients struggling with weight loss. There are limited data available for most of these supplements contrary to the claims laid by the mainstream media. Due to lack of awareness, this patient population is at high risk of adverse effects. We present a case of severe acidosis secondary to ketogenic diet and acetic acid (vinegar) ingestion. The use of dietary acetic acid is usually well tolerated; however, in this case, the large quantities and presence of acute renal injury may have worsened the acidosis. Severe ketosis in setting of ketogenic diets is a serious complication, which is infrequently reported in literature. Many of these diets and supplements may seem harmless, but as our case illustrates, when combined with other risk factors, patients can face adverse effects and even hospitalization. It is imperative that such dietary practices are physician supervised to avoid complications. With the recent surge of over-the-counter weight loss supplements and fat diets, physicians need to engage in dietary discussion with patients when attempting to lose weight.

Nasal myiasis in myasthenic crisis, a case report and literature review.

We are reporting a unique case of drosophila larva nasal myiasis (NM) in a 72-year-old male patient admitted to the ICU with diffuse muscle weakness and respiratory failure due to myasthenia gravis crisis and septic shock due to pseudomonas pneumonia. The myiasis was noticed on the third day of admission two days following traumatic insertion of a nasogastric tube. The patient underwent nasal endoscopic mechanical extraction and lidocaine nasal spray with saline nasal flushes. To our knowledge, this is the first case report of NM in a myasthenia gravis (MG) patient. Chronic muscle weakness in MG patients might play a role in having NM as these patients are less likely to be able to protect themselves from flies. Managing NM in our patient was challenging due to the potential neurologic side effects of most of treatment options mentioned in the literature.

Cervical Spine Ischemic Stroke Complicated by Spastic Quadriparesis and Ogilvie Syndrome: A Case Report and Literature Review.

Infarction or ischemia of the spinal cord is a rare entity and is often misdiagnosed as inflammatory myelopathy in acute settings. Atherosclerotic disease can affect spinal arteries, leading to cord ischemia with clinical presentation mixed with myelopathy. We present a case of a 66-year-old male who came to the hospital with unsteady gait and numbness of all extremities without associated pain for the past 48 hours. The neurological examination on admission directed the diagnosis towards myelopathy of the cervical spine. However, the initial magnetic resonance imaging (MRI) of the cervical spine demonstrated gliosis and restricted diffusion of the cord with multilevel neuroforaminal stenosis but without central canal stenosis or cord compression. The MRI brain, cerebrospinal fluid analysis, and rheumatologic evaluation were unremarkable. Four days into the clinical course, the patient developed weakness and spasticity of all extremities prompting further evaluation. Computed tomography angiography (CTA) scan of the head and neck revealed right vertebral artery occlusion and intracranial atherosclerotic disease. He was started on aspirin and clopidogrel for secondary risk reduction. The hospital course was further complicated by Ogilvie syndrome (OS), and the patient underwent uncomplicated cecostomy.

Thyrotoxicosis-Induced Cardiogenic Shock with Encephalopathy and Acute Respiratory Distress: A Case Report and Literature Review.

Thyrotoxicosis-induced cardiomyopathy and cardiogenic shock (CS) can lead to sudden mortality in adults. Hemodynamic instability and collapse occur due to functional alterations in both peripheral circulation and myocardium. Thyroid storm (TS) increases preload and decreases afterload along with an increase in cardiac contractility and heart rate leading to high output acute failure. We present a case of a 30-year-old female who presented with a complaint of watery diarrhea and dehydration for almost a week. At her visit to the emergency room, she was unresponsive with hemodynamic collapse leading to altered mental status and tachycardia. The computed tomography (CT) scan of head was non-contributory. The condition worsened with respiratory distress, and eventually, mechanical ventilation with intubation was completed. Further, laboratory workup showed acute thyrotoxicosis. The severe cardiomyopathy on echocardiography with compromised left ventricle function and diffuse pulmonary congestion led to acute respiratory distress syndrome (ARDS). The multi-organ failure, impending ARDS and CS with encephalopathy led to the sudden death of a patient within 24 hours of intensive care unit (ICU) stay before even extracorporeal membrane oxygenation (ECMO) could be started.

Developmental vascular anomaly associated hemi facial spasms and botox injections therapy.

Hemifacial spasm (HFS) is characterized by involuntary synchronous contractions or spasms of one side of the face, usually beginning around the eye. They are typically brief, irregular clonic movements but are occasionally tonic. We present a case of a 41-year-old female who presented to the neurology clinic with complaints of recurrent right facial spasms. These involuntary spontaneous movements had affected her quality of life. The neuroimaging revealed the vascular malformation right cranial nerves (CN) VII/VIII complex. It was considered to be responsible for the patient's HFSs. The patient responded well symptomatically to the botox injections without any neurovascular decompression.

Noncontrast CT versus Perfusion-Based Core Estimation in Large Vessel Occlusion: The Blood Pressure after Endovascular Stroke Therapy Study.

BACKGROUND AND PURPOSE: The 2018 AHA guidelines recommend perfusion imaging to select patients with acute large vessel occlusion (LVO) for thrombectomy in the extended window. However, the relationship between noncontrast CT and CT perfusion imaging has not been sufficiently characterized >6 hours after last known normal (LKN). METHODS: From a multicenter prospective cohort of consecutive adults who underwent thrombectomy for anterior LVO 0-24 hours after LKN, we correlated baseline core volume (rCBF < 30%) and the Alberta Stroke Program Early CT Scale (ASPECTS) score. We compared perfusion findings between patients with an unfavorable ASPECTS (<6) against those with a favorable ASPECTS (≥6), and assessed findings over time. RESULTS: Of 485 enrolled patients, 177 met inclusion criteria (median age: 69 years, interquartile range [IQR: 57-81], 49% female, median ASPECTS 8 [IQR: 6-9], median core 10 cc [IQR: 0-30]). ASPECTS and core volume moderately correlated (r = -.37). A 0 cc core was observed in 54 (31%) patients, 70% of whom had ASPECTS <10. Of the 28 patients with ASPECTS <6, 3 (11%) had a 0 cc core. After adjustment for age and stroke severity, there was a lower ASPECTS for every 1 hour delay from LKN (cOR: 0.95, 95% confidence of interval [CI]: 0.91-1.00, P = .04). There was no difference in core (P = .51) or penumbra volumes (P = .87) across patients over time. CONCLUSIONS: In this multicenter prospective cohort of patients who underwent thrombectomy, one-third of patients had normal CTP core volumes despite nearly three quarters of patients showing ischemic changes on CT. This finding emphasizes the need to carefully assess both noncontrast and perfusion imaging when considering thrombectomy eligibility.

Thrombectomy in DAWN- and DEFUSE-3-Ineligible Patients: A Subgroup Analysis From the BEST Prospective Cohort Study.

BACKGROUND: Because of the overwhelming benefit of thrombectomy for highly selected trial patients with large vessel occlusion (LVO), some trial-ineligible patients are being treated in practice. OBJECTIVE: To determine the safety and efficacy of thrombectomy in DAWN/DEFUSE-3-ineligible patients. METHODS: Using a multicenter prospective observational study of consecutive patients with anterior circulation LVO who underwent late thrombectomy, we compared symptomatic intracerebral hemorrhage (sICH) and good outcome (90-d mRS 0-2) among DAWN/DEFUSE-3-ineligible patients to trial-eligible patients and to untreated DAWN/DEFUSE-3 controls. RESULTS: Ninety-eight patients had perfusion imaging and underwent thrombectomy >6 h; 46 (47%) were trial ineligible (41% M2 occlusions, 39% mild deficits, 28% ASPECTS <6). In multivariable regression, the odds of a good outcome (aOR 0.76, 95% CI 0.49-1.19) and sICH (aOR 3.33, 95% CI 0.42-26.12) were not different among trial-ineligible vs eligible patients. Patients with mild deficits were more likely to achieve a good outcome (aOR 3.62, 95% CI 1.48-8.86) and less sICH (0% vs 10%, P = .16), whereas patients with ASPECTS <6 had poorer outcomes (aOR 0.14, 95% CI 0.05-0.44) and more sICH (aOR 24, 95% CI 5.7-103). Compared to untreated DAWN/DEFUSE-3 controls, trial-ineligible patients had more sICH (13%BEST vs 3%DAWN [P = .02] vs 4%DEFUSE [P = .05]), but were more likely to achieve a good outcome at 90 d (36%BEST vs 13%DAWN [P < .01] vs 17%DEFUSE [P = .01]). CONCLUSION: Thrombectomy is used in practice for some patients ineligible for the DAWN/DEFUSE-3 trials with potentially favorable outcomes. Additional trials are needed to confirm the safety and efficacy of thrombectomy in broader populations, such as large core infarction and M2 occlusions.

Blood Pressure after Endovascular Therapy for Ischemic Stroke (BEST): A Multicenter Prospective Cohort Study.

Background and Purpose- To identify the specific post-endovascular stroke therapy (EVT) peak systolic blood pressure (SBP) threshold that best discriminates good from bad functional outcomes (a priori hypothesized to be 160 mm Hg), we conducted a prospective, multicenter, cohort study with a prespecified analysis plan. Methods- Consecutive adult patients treated with EVT for an anterior ischemic stroke were enrolled from November 2017 to July 2018 at 12 comprehensive stroke centers accross the United States. All SBP values within 24 hours post-EVT were recorded. Using Youden index, the threshold of peak SBP that best discriminated primary outcome of dichotomized 90-day modified Rankin Scale score (0-2 versus 3-6) was identified. Association of this SBP threshold with the outcomes was quantified using multiple logistic regression. Results- Among 485 enrolled patients (median age, 69 [interquartile range, 57-79] years; 51% females), a peak SBP of 158 mm Hg was associated with the largest difference in the dichotomous modified Rankin Scale score (absolute risk reduction of 19%). Having a peak SBP >158 mm Hg resulted in an increased likelihood of modified Rankin Scale score 3 to 6 (odds ratio, 2.24 [1.52-3.29], P<0.01; adjusted odds ratio, 1.29 [0.81-2.06], P=0.28, after adjustment for prespecified variables). Conclusions- A peak post-EVT SBP of 158 mm Hg was prospectively identified to best discriminate good from bad functional outcome. Those with a peak SBP >158 had an increased likelihood of having a bad outcome in unadjusted, but not in adjusted analysis. The observed effect size was similar to prior studies. This finding should undergo further testing in a future randomized trial of goal-targeted post-EVT antihypertensive treatment.

Toxic Encephalopathy After Relapsed Indolent Non-Hodgkin's Lymphoma Following Abrupt Discontinuation of Idelalisib (ZYDELIG®).

Idelalisib is a delta isoform-specific, phosphoinositide 3-kinase (PI3-K) inhibitor. It has been used as a single agent for the treatment of relapsed or refractory small lymphocytic lymphoma (SLL), follicular non-Hodgkin's lymphoma (NHL), and in combination with rituximab for patients with chronic lymphocytic leukemia (CLL). We present a case of a 77-year-old man diagnosed with SLL and was treated with multiple chemotherapeutic regimens in the past. Considering multiple relapses, he was started on idelalisib monotherapy almost 12 months ago. The treatment was stopped due to worsening neutropenia as well as mixed response on the scans. Almost, within one week of stopping the medication, he presented with complaints of altered mental status, hematuria, and worsening of generalized lymphadenopathy. This time, the patient was started on venetoclax (BCL-2 inhibitor) and rituximab which he is tolerating well without any complications.

Abdominal Epilepsy Masked with Hiccups in a Patient with Intracranial Malignant Glioma.

Abdominal hiccups are often masked by abdominal epilepsy (AE) in clinical settings. Spontaneous arrhythmic muscular movements sometimes raise the suspicion for abdominal myoclonus as well. AE is an atypical and rare cause of seizure disorder. It is a manifestation of different transient abdominal complaints correlating with abnormal electroencephalogram (EEG) changes and adequate response to anti-epileptic drugs. We present a case of an 80-year-old female who presented with an episode of tonic-clonic seizure that lasted for almost 10 minutes. The patient was confused and had a facial droop. She had another episode of seizure with a perseverative speech followed by left facial drooping and left upper extremity weakness. She continued having fluctuating mental status and left-sided hemiparesis with intermittent abdominal twitching. She was getting more bradykinetic than bradyphrenic. The computed tomography (CT) scan of the head and magnetic resonance imaging (MRI) of the brain showed a parietal lobe mass that was confirmed on biopsy as malignant glioma. The long-term video monitoring EEG report showed the occurrence of persistent right parietal spikes with background slowing. The brain mass was later treated with radiation therapy and surgery.

Frequency of Ischemic Stroke Subtypes Based on Toast Classification at a Tertiary Care Center in Pakistan.

BACKGROUND: The purpose of this study was to determine the frequency of ischemic stroke subtypes based on Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification at a tertiary care center in Pakistan. MATERIALS AND METHODS: A cross-sectional study was conducted in Stroke Unit of Shifa International Hospital, Islamabad. We included 145 patients who presented to us from November 2015 to February 2016 with radiological confirmed neurological deficits consistent with ischemic stroke. The causes of ischemic stroke were classified according to TOAST criteria. Regression analysis and Chi-square test were used to compute P value. RESULTS: Among the 145 patients diagnosed with ischemic stroke, there were 54.1% males and 45.9% females with a mean age of 65 ± 14 years. Nearly 62.7% patients had hypertension (HTN) as the most common risk factor, followed by 38.6% diabetes mellitus (DM), 27.5% heart failure, 19.3% valvular disease, 18.6% previous stroke, 16.4% smoking, 15.1% dyslipidemia, 13.7% ischemic heart disease, and 13.1% atrial fibrillation. HTN was significantly associated with large vessel disease (P = 0.028). DM was significantly associated with small vessel disease (P = 0.001). Smoking and atrial fibrillation both were associated with unknown etiology of stroke (P = 0.001 and P = 0.039, respectively). Most common etiology of stroke was cardioembolism (40%), and atrial fibrillation is found to be the most common cause of cardioembolic stroke with 30.6% incidence. CONCLUSION: Our study concludes that cardioembolic stroke is the most common cause of acute ischemic stroke in our stroke unit. Atrial fibrillation is found to be the most common cause of cardioembolic stroke.

Comparison of outcomes of tubed versus tubeless percutaneous nephrolithotomy in children: A single center study.

OBJECTIVE: To evaluate and compare the effectiveness of tubeless percutaneous nephrolithotomy (PCNL) and tubed PCNL by using small bore nephrostomy tube (12Fr) in children for the management of nephrolithiasis. MATERIAL AND METHODS: This study was a retrospective analysis of 35 children where tubed PCNL (Group 1) was done in 18, and tubeless PCNL (group 2) in 17 patients from January 2010 to December 2016. Charts were reviewed for age, mass, stone size, operative time, hospital stay and stone-free rates. These variables were compared between the two groups. SPSS version 21 was used for data analysis. The data were shown as mean±standard deviation for continuous variables. Categorical variables were presented in percentages. RESULTS: There is no difference in terms of age, stone sizes, operative times, hospital stays, stone-free rates and post-PCNL complications between the two groups (p>0.05). The mean drop in hemoglobin level was 0.7±0.1 g/dL and 1.3±0.2 g/dL in Groups 1 and 2, respectively (p=0.01). CONCLUSION: Tubeless PCNL in children is a safe option in well selected cases.

Management of Massively Enlarged Multiple Hydatid Cysts in the Liver of a Pediatric Patient.

Multiple hydatid cysts in the liver are a very rare occurrence in childhood. We present a similar case in a nine-year-old girl, a resident in a rural community, who presented with two hydatid cysts in her liver. The cysts were operated upon by a pediatric surgeon. The laboratory findings of this patient showed peripheral blood eosinophilia, elevated white blood cells, and liver enzymes. The serology was positive. The ultrasonography showed cystic masses in the liver, and the diagnosis of hydatid cysts was eventually confirmed by computed tomography (CT) of the abdomen.

Marked Atrophic Changes of the Brain in a Patient with Subacute Sclerosing Panencephalitis.

Subacute Sclerosing Panencephalitis (SSPE) is a debilitating disorder associated with the measles infection in childhood. It is a very rare manifestation in children. It usually presents with measles before the age of two. We report a similar case of SSPE in a 14-year-old girl who developed this life-threatening condition in spite of receiving the measles vaccination. Despite the vaccination, the patient had suffered from measles before the age of two. This highlights the dilemma of ineffective vaccinations in developing countries. We also describe the radiologic features of SSPE in this patient, with marked atrophy seen in the occipital region following hyperintensities noticed at a relatively earlier stage.

Prevalence of Obesity in Carpal Tunnel Syndrome Patients: A Cross-Sectional Survey.

Carpal tunnel syndrome (CTS) is the most common compressive entrapment neuropathy caused by the compression of the median nerve at the wrist space known as the carpal tunnel. The epidemiologic factors related to CTS include genetic, medical, social, vocational, and demographic factors. The common symptoms experienced include pain, paresthesia, and numbness in the median nerve distribution. If left untreated, it can lead to irreversible median nerve damage, causing a loss of hand function. Body mass index (BMI) has been attributed as a risk factor for the development of CTS. We planned to determine the frequency of obesity among CTS patients in the neurophysiology department of a tertiary care center in Islamabad, Pakistan. The survey was designed as a cross-sectional descriptive study from March 2016 to August 2016 using a consecutive nonprobability sampling technique. A total of 112 patients with a mean age of 54 ± 5 years were included in the study. In the study population, 39 patients (35 percent) were males and 73 were females (65 percent). Based on BMI, 74 patients (66 percent) had a normal weight and 38 (34 percent) were obese. The frequency of obesity in our study was 34 percent, excluding the other comorbid conditions, which is quite high. Targeted therapy in those with CTS should also include weight reduction measures because obesity poses a cause-and-effect relationship for both the severity and the pathogenesis of CTS.

Cardiovascular Dysfunction Presenting as Autonomic Dysreflexia in a Patient with Spinal Cord Injury.

Autonomic dysreflexia (AD) is a medical emergency that is characterized by hypertension as an autonomic response to noxious stimuli in patients with a history of spinal cord injury at the level of T6 or above. We present the case of a 31-year-old Caucasian male with a history of spinal cord injury at the level of C3-C4, with symptoms described as recurring episodes of hypertension with flushing and sweating above the level of the lesion for the past five to six years. His symptoms are triggered by bowel distention, excitement, a bumpy car ride, or a simple turning of the neck to the left. Physical examination and laboratory studies ruled out other possible differentials (e.g., migraines, pheochromocytoma). As a result, AD was diagnosed.

Breast Cancer Metastases to the Gastrointestinal Tract Presenting with Anemia and Intra-abdominal Bleed.

Signet ring adenocarcinoma of the breast with synchronous metastasis to the gastrointestinal (GI) tract is a rare occurrence, typically presenting with abdominal pain, dyspepsia, or GI bleed. We report a case of metastatic breast cancer presenting with a complaint of anemia. A further diagnostic evaluation revealed generalized lymphadenopathy, nodular thickening of the urinary bladder wall, bone lesions, and enlarged pancreas. Biopsies from the lymph nodes, pancreatic biopsy, and bladder nodule all revealed a signet cell carcinoma. An upper and lower GI endoscopy revealed multiple ulcerated gastric mucosal nodules and polypoid folds in the cecum and proximal ascending colon; the biopsies from these lesions were also positive for signet ring cell adenocarcinoma.

Anti-n-Methyl-d-Aspartate-Receptor (NMDAR) Encephalitis in Association with Ovarian Teratoma.

Anti-N-methyl-D-aspartate-Receptor (NMDAR) encephalitis is an autoimmune disorder with a multifaceted presentation that involves memory deficits, psychiatric symptoms, and autonomic instability. This case report describes the classic presentation of Anti-NMDAR encephalitis and highlights its association with ovarian teratomas. We present a 26 -year-old female who came in with new onset seizures and altered mentation who subsequently developed automatism. Electroencephalograms (EEG) showed left frontal spikes and right temporal delta activity. Magnetic resonance imaging (MRI) revealed right temporal hyper-intensity. The diagnosis was established with positive anti-NMDAR antibodies in the cerebrospinal fluid (CSF). The patient was initially treated with steroids and valproic acid, however, her condition progressively worsened. A five-day course of intravenous immunoglobulins (IVIG) was started followed by rituximab. The clinical course was complicated with the patient developing neutropenic fever and cerebrospinal fluid cultures (CSF) growing methicillin-sensitive Staphylococcus aureus (MSSA). She underwent pelvic imaging which showed a right ovarian teratoma. Evidence suggests that removal of ovarian tumor leads to better clinical and mortality outcomes in patients with Anti-NMDAR encephalitis. It is important for the internist to consider paraneoplastic syndromes in patients with Anti-NMDAR encephalitis.

Combination Therapy for Multidrug-Resistant Klebsiella Pneumoniae Urinary Tract Infection.

Hospital-acquired multidrug-resistant (MDR) Klebsiella infection is posing a significant challenge to physicians all around the world. The spread of multiple antibiotic resistance among various members of bacteria continues to be a significant clinical threat. Antibiotic susceptibility testing is the initial step in optimizing the appropriate antibiotic therapy for infections with MDR Klebsiella. We report a case of MDR Klebsiella urinary tract infection (UTI) in a patient following a trimalleolar fracture, which was appropriately treated with a combination of amikacin and meropenem.
