Osteomyelitis Caused by Citrobacter koseri in a Young Immunocompetent Man.

Citrobacter koseri is a non-sporulating, motile, gram-negative, facultative anaerobic bacteria found in various environmental sources, including the human intestine. It is considered an opportunistic infection as it typically causes infection in newborns, elderly, and immunocompromised patients. Common sites of infection are the urinary tract, gastrointestinal system, and respiratory tract in immunocompromised adults, as well as the bloodstream and meninges in newborns. However, osteomyelitis secondary to C. koseri is very rare. We present an unusual case of Citrobacter osteomyelitis in a healthy young man with no identifiable risk factors.

Right Upper Quadrant Pain: A Rare Presentation of Diverticulitis.

Acute diverticulitis is a prevalent medical condition with increasing incidence rates. While the sigmoid colon is the most commonly affected part of the large intestine, there have been occurrences of right-sided diverticulitis although uncommon. We present a case report highlighting the atypical presentation of diverticulitis in a 27-year-old female patient. The patient experienced right upper and epigastric pain and was ultimately diagnosed with right-sided diverticulitis, supported by her CT imaging findings. This uncommon presentation underscores the importance of considering diverse clinical manifestations when diagnosing and managing diverticulitis.

Exploring the Efficacy of Ketamine as an Anesthetic and Antidepressant in Postpartum Depression: A Case Study Analysis.

Postpartum depression is a common mental health disorder that affects women within six months after giving birth. It is characterized by sadness, anxiety, and extreme fatigue, which can significantly impact a woman's daily functioning and ability to care for her newborn. While traditional treatments for postpartum depression include therapy and medication, recent studies have shown promising results using ketamine. We present a case of a woman with a history of depression who delivered four children by cesarean section with debilitating postpartum depression in two births and no symptoms of depression in the births where she received ketamine during delivery.

Orbital B-cell Lymphoma Masquerading As Dry Eye Disease.

Orbital lymphoma is a rare tumor with an incidence of 2.02 per million per year. It can occur as a part of systemic lymphoma or spontaneously arise primarily in orbit. The most commonly reported malignant lymphoma is non-Hodgkin's lymphoma. The typical clinical finding includes exophthalmos, swelling, and limited eye movement. Our patient presented with dryness and irritation of the eye without signs of proptosis until months later. The definitive diagnosis of orbital lymphoma requires a biopsy. Still, imaging studies such as MRI and CT scans play a critical role in distinguishing benign from malignant lesions and invasion of local tissues. The treatment of orbital lymphoma is multidisciplinary, involving surgical resection, radiotherapy, and chemotherapy depending on the histological type of tumor and the presence of metastasis.

Is Losing Weight Worth Losing Your Kidney: Keto Diet Resulting in Renal Failure.

Keto diet is defined as a high-fat, adequate-protein, and low-carbohydrate nutrition which forces the body to burn fats and use an alternative metabolic fuel resource by stimulating endogenous ketone production. The standard range of ketones in ketosis is up to 3.00mmol/L, and anything beyond this level can result in serious medical conditions. This diet's most common and easily reversible consequences are constipation, low-grade acidosis, hypoglycemia, kidney stones, and increased lipid in the blood. We present a case of a 36-year-old female who presented with pre-renal azotemia after starting a keto diet regimen.

Thoracic Gut Entrapment Presenting As Intractable Hypoxia: A Case Report of Chilaiditi Syndrome.

We present a rare case of a patient who had intractable hypoxia and was found to have Chilaiditi syndrome. The hypoxia and respiratory symptoms resolved after bowel decompression and relief of the mass effect of the entrapped gut in the thorax. Chilaiditi sign is the interposition of the colon between the liver and diaphragm. Colonic interposition is a common asymptomatic radiological finding, in Chilaiditi syndrome, patients experience symptoms such as abdominal pain, constipation, respiratory distress, and chest pain.

Suprapubic Osteomyelitis in an Intravenous Drug User: A Case Report.

We discuss a case of methicillin-resistant Staphylococcus aureus (MRSA) osteomyelitis pubis in a 45-year-old female patient with an active history of intravenous (IV) drug injection. While IV drug users are typically infected with Pseudomonas aeruginosa in cases of osteomyelitis of the pubic symphysis, our patient presented with a rare case of MRSA infection of the pubis symphysis. In this case, an investigation using magnetic resonance imaging (MRI), elevated levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and culture was consistent with the diagnosis of osteomyelitis. Osteomyelitis pubis is an infection that causes necrosis and destruction of the pubic bone. This condition remains a rarity, as less than 1% of osteomyelitis cases are reported to involve the pubic symphysis, thus contributing to the delays observed between onset of symptoms and diagnosis. The goal of this case report is to promote awareness of this phenomenon to hasten diagnosis and early treatment. The recommended treatment is with IV antibiotics for MRSA coverage for four to six weeks' duration; however, our patient left against medical advice.

Secondary Immune Thrombocytopenic Purpura Due to Primary Epstein- Barr Virus Infection.

A rare complication of infectious mononucleosis is immune thrombocytopenic purpura (ITP). The majority of people affected by Epstein-Barr Virus (EBV) are below the age of 30, while ITP is usually seen with peaks of incidence in the elderly and children. The unique case of an otherwise healthy 22-year-old female will be discussed, with an initial presentation of ecchymosis, rash, and epistaxis, and was subsequently found to have severe thrombocytopenia. The diagnosis of primary EBV infection due to EBV was eventually made, responsive to intravenous (IV) Methylprednisolone. It is important to consider primary EBV infection in the differential diagnosis of a patient who presents with acute thrombocytopenia.

Thyroid Eye Disease With Divergence Insufficiency Causing Recurrent Falls in an Elderly Patient.

Recurrent falls are a common cause of morbidity in the elderly population, as more than one-third of individuals aged 65 years or older experience falls each year. Falls remain a multifactorial phenomenon that can potentially result in devastating debilitation and hence require proper medical attention and management. In an elderly patient presenting with recurrent falls, the workup for differential diagnoses remains wide with various causes such as postural hypotension, syncope, seizures, arrhythmia, medication-induced, and cognitive impairment. In this report, we discuss an interesting case of recurrent falls in an elderly woman with hyperthyroidism who was repeatedly found to have unremarkable lab results and negative imaging studies. She was later diagnosed with divergence insufficiency with intermittent esotropia secondary to thyroid ophthalmopathy, which was the cause of her underlying horizontal diplopia contributing to her falls. This can cause blurry vision at further distances, which is observed especially in individuals older than 50 years. Treatment typically involves prism therapy, surgery in refractory patients, and, currently, novel therapy using teprotumumab infusion. The patient was referred to see a strabismus specialist for prism prescription and possible surgical intervention. In elderly patients with a history of recurrent falls, a comprehensive visual exam should be strongly considered, especially for individuals with repeated negative workups, to prevent further testing or procedures.

Recurrent Bacterial Infections in Cutaneous T-cell Lymphoma.

Cutaneous T-cell lymphoma (CTCL) is a dermatologically manifesting immune cell disorder. We present a case of a 76-year-old female with a past medical history of CTCL, presenting with cellulitis of the left foot. After diagnosis of CTCL, the patient was admitted multiple times for treatment of cutaneous and soft-tissue infections with methicillin-resistant Staphylococcus aureus. Her recurrent infection with S. aureus had led to treatment for sepsis and a below-knee amputation on the right during prior hospitalizations. On this admission, the patient was treated with intravenous vancomycin and cefepime as in-patient and oral linezolid as out-patient. Recent articles show that patients with CTCL have an increased tendency to harbor S. aureus, which leads to recurrent infections. Additionally, evidence suggests that S. aureus toxins aid the progression of CTCL by helping the cancer to escape immune regulation. Our patient demonstrates this unique relationship between CTCL and S. aureus, and moreover, we make a case that S. aureus infection in CTCL, as compared to that in other dermatitis, should be better managed to not exacerbate the disease.

Nocardia in an Immunocompetent Host Masquerading As Lung Cancer: A Case Report.

Nocardiosis is generally regarded as an opportunistic infection that can present as a cutaneous, pulmonary, or disseminated disease based on host immunity status. Pulmonary nocardiosis is typically seen in immunocompromised patients; however, it can rarely be present in immunocompetent patients. We present a rare case of an immunocompetent patient who was thought to have a lung malignancy but was found to have pulmonary nocardiosis upon further investigation.

Epstein-Barr Virus-Positive Not Otherwise Specified (EBV+ NOS) Lymphoma Presentation of Primary Bone Tumor Underlying a Pathological Fracture.

Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin's lymphoma (NHL) and accounts for approximately 25% of all NHLs in developed countries. The patients usually present with constitutional symptoms and rapidly enlarging lymphadenopathy and symptomatic mass typically located in the neck or abdomen, along with an aggressive disease course. Most of the patients present with advanced disease with 60% presenting with stage 3 or 4, and those who present with extranodal involvement are usually seen at an earlier stage. Different conditions are associated with non-Hodgkin's lymphoma ranging from hereditary immunodeficiency disorders, autoimmune disorders, infections such as HIV, Epstein-Barr virus (EBV), hepatitis C virus (HCV), Helicobacter pylori, and drugs such as immunosuppressants and chemotherapeutic agents. Epstein-Barr virus (EBV) is the main etiology of DLBCLs with an identified cause and it accounts for 10% of all DLBCLs.  We report a case of a 51-year-old woman who came with a non-traumatic left femur fracture and was subsequently found to have EBV-positive DLBCL. Lymphoma commonly presents as a lymph node swelling and it's uncommon to present as primary bone disease.

The Need to Anticoagulate Patients With Splenic Vein Thrombosis.

Splenic vein thrombosis (SVT) is a well-recognized complication of acute and chronic pancreatitis. It is associated with complications of significant gastrointestinal bleeding and high morbidity if the thrombus propagates. There is a need to consider several factors in choosing whether to anticoagulate the patient. We report a case of SVT in a patient with a previous history of pancreatitis who presented with abdominal pain, nausea, and vomiting to the hospital. At the hospital, a CT scan revealed SVT. This case highlights the importance of undergoing further studies regarding anticoagulation for treating SVT in patients at risk for gastrointestinal bleeding.

Dysphagia Lusoria Causing Aspiration Pneumonitis in a Patient With Recurrent Pancreatitis.

Dysphagia lusoria (DL) occurs due to an aberrant right subclavian artery (ARSA) compressing the esophagus resulting in dysphagia, odynophagia, and/or reflux symptoms. It is diagnosed by barium esophagram followed by a CT scan or MRI. In this case report, there is a 44-year-old male with a chronic history of reflux and a cough that presents after a meal. The case was complicated due to the history of the patient's alcoholism with recurrent pancreatitis. A CT scan was obtained during his admission, which showed pleural effusion, atelectasis, aspiration pneumonia, and an incidental aberrant RCA. Although DL is a rare pathology, 60%-80% of patients remain asymptomatic, and patients with symptoms can be managed conservatively or surgically, depending on their severity.

What Works for One May Not Work for Another: A New Warning for Modafinil.

Narcolepsy is a clinical syndrome of hypothalamic disorder characterized by several sleep-wake disorders. The most common features include daytime sleepiness associated with hallucinations (hypnagogic and hypnopompic hallucinations) at the transition time of sleep-wake time, cataplexy or sudden loss of muscle tone, and sleep paralysis. We present a case of a patient affected with both narcolepsy and postural orthostatic tachycardia syndrome (POTS). POTS is a rare disorder characterized by orthostatic intolerance and abnormal autonomic response while sustaining an upright posture. In this case report, we highlight the impact of POTS on the choice of pharmacotherapy for narcolepsy.

Exacerbation of Secondary Cold Agglutinin Syndrome in the Setting of SARS-CoV-2.

In this report, we present a case of exacerbation of cold agglutinin syndrome (CAS) potentially due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia. An 83-year-old female with a history of cold agglutinin hemolytic anemia presented with shortness of breath, productive cough, worsening orthopnea, darkening fingers and urine, and jaundice. Laboratory investigations found elevated white blood cells (WBC) and total bilirubin, severely low hemoglobin, and positive direct Coombs test. Moreover, SARS-CoV-2 RNA was also found to be positive in a sample from the nasal swab by reverse transcription-polymerase chain reaction (RT-PCR), indicating exacerbation of CAS secondary to viral coronavirus 2019 (COVID-19) infection. A treatment regime for SARS-CoV-2 consisting of five days of remdesivir and seven days of dexamethasone 6 mg IV was initiated, resulting in significant improvement in the patient's condition.

Antipsychotic Medication-Induced Hyperthermia Leading to Cerebrovascular Accident: A Case Report.

Antipsychotic medications are used in the management of schizophrenia. Antipsychotic medications treat both positive and negative symptoms via the dopamine D2 receptor and serotonin 5-HT2A blockade pathway. Side effects include hyperprolactinemia, prolonged QTc, and neuroleptic malignant syndrome. However, antipsychotic medication-induced hyperthermia potentiating a cerebrovascular accident (CVA) is a rare side effect that is less well known. A 47-year-old male presented to the emergency department (ED) via emergency medical services for altered mental status. He was given naloxone without improvement in mental status. His glucose was 110 mg/dL. Upon presentation to the ED, he was hyperthermic (106.7 degrees Fahrenheit) and tachycardic (heart rate of 160's beats/minute). Home medications included risperidone and fluphenazine. After the resolution of his hyperthermia, he had a right-sided facial droop concerning a cerebrovascular accident. Magnetic resonance imaging (MRI) of the brain confirmed an early/acute subacute right cerebellar infarction. The patient received optimal treatment; his mental status returned to baseline, and he was discharged home without antipsychotic medications. Patients who are prescribed antipsychotics should be aware of the potentially fatal adverse events that can occur from these medications. Thermoregulation may be impaired in these patients, resulting in significant hyperthermia, in which case antipsychotic medications should be discontinued.

The Development of Multiple Periprosthetic Joint Infections in Conjunction With Ibrutinib Therapy.

Periprosthetic joint infections (PJI) can be subcategorized into acute postoperative infections, occurring within three months of implantation, and delayed onset infections, occurring after three months of implantation. PJIs can be caused by numerous infectious etiologies. Here, we describe a unique case of a patient with a history of bilateral shoulder and knee replacements over five years. The patient received a diagnosis of Waldenströms macroglobulinemia five years before her admission but deferred ibrutinib treatment until one year before her admission. We believe that the timeline coincides with the development of multiple PJIs secondary to ibrutinib therapy. The patient presented with bilateral shoulder and knee pain and swelling, following a flu-like illness that had resolved one year before the admission. Her joint symptoms did not subside along with the remaining flu-like symptoms. Initially, her symptoms served as clues to the diagnosis; however, the diagnosis was finally made and supported by joint aspiration. The patient was treated with vancomycin 1.25 g in sodium chloride 0.9% 250 mL intravenous piggyback every 24 hours for the treatment of PJI and oral daptomycin 500 mg daily for six weeks as prophylaxis for PJI. In conclusion, physicians need to consider the development of PJIs when prescribing immunosuppressive therapy, as well as an early diagnosis to prevent further complications.

Treatment of Elsberg Syndrome Causes Fever of Unknown Origin Attributable to Drug Reaction.

A 56-year-old male with a history of non-adherence to HIV anti-retroviral therapy (ART) presented with Elsberg syndrome - varicella reactivation causing fever, painful dermatomal rash, weakness of bilateral lower extremities, and urinary and bowel dysfunction. On the third day of hospitalization, the patient developed altered mental status. An investigation for encephalitis and myelitis revealed a CD4 count of 150 cells/uL, viral load of about 150,000 copies/mL, and MRI of the lumbar spine demonstrating thickening of the cauda equina. Cerebrospinal fluid (CSF) from lumbar puncture confirmed the presence of varicella-zoster virus (VZV). Treatment with acyclovir for 21 days was initiated. However, the patient developed a persistent fever. Evaluation for the source of the fever resulted in identification of anti-viral therapy as the cause. In conclusion, the present report provides a unique example of acyclovir-induced fever developed on treatment of Elsberg syndrome.
