Inappropriate Use of Intravenous PPI for Stress Ulcer Prophylaxis in an Inner City Community Hospital

Background Proton pump inhibitors (PPIs) are used for the treatment and prophylaxis of variety of acid peptic conditions including stress ulcers. There has been a persistent practice of their inappropriate use for stress ulcer prophylaxis. Purpose of our study was to measure the inappropriate use of Intravenous Proton Pump Inhibitors for stress ulcer prophylaxis and to estimate the financial burden. Methods We carried out a retrospective, analytic study from July 2008 to June 2009 in internal medicine department. Hospital pharmacy records were used to identify all patients who received IV PPI during hospital stay. Seventy-five percent of records were randomly chosen (n=1104). PPI application was defined as indicated according to AGA guidelines. Results Intravenous proton pump inhibitor (IV PPI) was prescribed for 68.5% of patients without any proper indication. The estimated cost of medication for inappropriate IV PPIS use during the study year was 18337 USD. Conclusions A more rational use of PPI will have better impact on health care cost and is likely to add to patient safety.

Obstructive fibrinous tracheal pseudomembrane.

Obstructive fibrinous tracheal pseudomembrane (OFTP) is a relatively rare cause of failed extubation. OFTP may be more common than described in the literature. OFTP results from ischemic injury to tracheal mucosa and may be the initial stage of the development of tracheal stenosis. Early diagnosis and treatment can prevent re intubation and mortality. We present a rare case of OFTP. The patient was intubated for 3 days for asthma exacerbation and was appropriately discharged. The patient was seen the second time in the emergency room and was treated for asthma exacerbation on the same day. Because of persistent symptoms after 3 days, CT scan of the chest was performed, which indicated necrotizing tracheitis with gas formation within the tracheal wall. Bronchoscopy showed no evidence of necrosis, but there was a thick white plaque toughly adherent to the tracheal wall.

Non-islet cell tumor hypoglycemia associated with uterine leiomyomata.

OBJECTIVE We report a case of non-islet cell tumor hypoglycemia (NICTH) in a patient with large leiomyomata. METHODS We present the clinical, laboratory, and pathologic findings of a diabetic patient who presented with recurrent hypoglycemia later linked to uterine leiomyomata. RESULTS An 80-year-old woman with diabetes was admitted after falling at home. She reported dizziness and had recorded low capillary blood glucose despite discontinuing her diabetic medication prior to admission. Her physical examination was remarkable for nonorthostatic vital signs, normal cardiovascular and lung examination, and a pelvi-abdominal mass the size of a gravid uterus at 28 weeks of gestation. After receiving a 50% dextrose infusion, she became alert with no focal neurological deficit. Capillary blood glucose rose from 31 mg/dL to 110 mg/dL. A pelvic sonogram confirmed fibromyomata. She was initially treated with steroids after a hormonal profile suggested NICTH (normal fasting insulin, C-peptide, cosyntropin and glucagon stimulation tests, and negative insulin antibodies). Insulinlike growth factor (IGF) levels were IGF-1, 69 ng/mL and IGF-2, 782 ng/mL, and the IGF-2/IGF-1 ratio was 10.8. The patient underwent a total abdominal hysterectomy. Pathology reported a 3-kg uterus with multiple, large cellular fibromyomas. After steroids were discontinued, she became hyperglycemic requiring insulin and oral diabetic agents. Repeat IGF-2 and IGF-1 measurements were 261 ng/mL and 36 ng/mL, respectively. She was discharged 2 weeks after surgery. CONCLUSION NICTH is a rare complication associated with large neoplasms. Leiomyomata should be included in the differential diagnoses of NICTH. Surgery is curative in such cases.

Use of flexible bronchoscopy in an adult for removal of an aspirated foreign body at a community hospital.

Foreign body aspiration (FBA) is more common in children than adults with about 80% occurring in children aged less than 15 years. FBA in adults is often overlooked as a potential cause of airway obstruction especially if there is no asphyxiation. We present a case of a 45-year-old male with alcohol abuse who presented with post-obstructive pneumonia secondary to aspiration of tooth of unknown duration. The tooth was removed via flexible bronchoscopy (FBr) and we will discuss the use of FBr for foreign body (FB) removal, which FB can be easily removed by FBr, and the different techniques and devices used for FB removal via FBr.

Unrecognized clozapine-related constipation leading to fatal intra-abdominal sepsis – a case report

Clozapine is the preferred antipsychotic used for the treatment of resistant schizophrenia with suicidal ideation. The drug is started at a low dose and gradually increased to a target dose of 300–450 mg/day. It is well known to cause agranulocytosis and neutropenia. Several cases of fatal sepsis have been reported in neutropenic patients and emphasis is placed on monitoring for agranulocytosis; however, clozapine also causes intestinal hypomotility and constipation, which if unrecognized can lead to intestinal obstruction, bowel necrosis, and intra-abdominal sepsis. Reduced behavioral pain reactivity in schizophrenics may alter the ability to express pain, potentially leading to a delay in the presentation for medical attention. We report a case of fatal intra-abdominal sepsis secondary to an unrecognized case of clozapine-related constipation.

Disseminated Mycobacterium avium intracellulare infection in an "immunocompetent" host.

We are reporting the case of a 37-year-old immunocompetent patient who presented with anterior chest wall swelling, jaw swelling and pain, back pain, night sweats, and unintentional weight loss. He underwent mediastinoscopy with lymph node biopsy, which revealed caseating and noncaseating granuloma and special stains positive for acid-fast bacteria. Cultures from two different sites surprisingly grew Mycobacterium avium intercellulare (MAI), and a diagnosis of disseminated MAI was made. He was switched from antituberculous treatment to MAI treatment.

Pseudo-thrombotic thrombocytopenic purpura presenting as multi-organ dysfunction syndrome: A rare complication of pernicious anemia

Objective: We present a rare case of pernicious anemia presented as multi-organ dysfunction syndrome, later found to have pseudo-thrombotic thrombocytopenic purpura. Methods: An 86-year-old female presented with respiratory distress, altered mental status, acute renal failure and was intubated in emergency room. She was found to have severe anemia, thrombocytopenia, high lactate, high lactate dehydrogenase and low haptoglobin. Peripheral smear revealed multilobulated neutrophils with schistocytes, poikilocytes and anisocytes. Results: She was admitted to intensive care unit for altered mental status, multi-organ dysfunction syndrome with severe metabolic acidosis in setting of hemolysis. She was intubated and managed with intravenous antibiotics and blood transfusion. Patient improved significantly after blood transfusion. Lactic acid normalized, acute kidney injury resolved and mentation improved after transfusion. Laboratory investigation revealed low vitamin B12, high methylmalonic acid, high homocysteine, high lactate dehydrogenase, low haptoglobin, high anti-parietal antibody and high anti-intrinsic factor antibody. Patient was diagnosed with pernicious anemia and pseudo-thrombotic thrombocytopenic purpura with concomitant intramedullary hemolysis. Her hematological parameters and her clinical condition improved significantly after starting therapy with cyanocobalamin. Conclusion: Pernicious anemia is a chronic disease with subtle presentation but may present as life-threatening complications. Hemolysis and pseudo-thrombotic thrombocytopenic purpura may present as multi-organ dysfunction syndrome which has dramatic response to appropriate therapy.

Relationship of symptoms with sleep-stage abnormalities in obstructive sleep apnea-hypopnea syndrome.

Background Patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) present with a variety of sleep-related symptoms. In polysomnography, sleep architecture is almost always abnormal, but it is not known which of the sleep-stage abnormalities are related to symptoms. Finding key sleep-stage abnormality that cause symptoms may be of therapeutic importance to alleviate symptoms. So far the mainstay of treatment is continuous positive airway pressure (CPAP)/bi-level positive airway pressure (BIPAP) therapy, but many patients are non-compliant to it. Correcting the sleep-stage abnormality that cause symptoms by pharmacotherapy may become an important adjunct to CPAP/BIPAP therapy. Methods A cross-sectional study. Adult subjects who attended a sleep laboratory for diagnostic polysomnography for a period of 1 month were recruited consecutively. OSAHS was diagnosed using American Academy of Sleep Medicine criteria. Subjects filled a questionnaire for symptoms prior to polysomnography. Results Thirty subjects, of whom 83.3% were obese, met diagnostic criteria, with males constituting 46.7% and females constituting 53%. Mean age was 53.40±11.60 years. Sleep architecture comprised N1 19.50±19.00%, N2 53.93±13.39%, N3 3.90±19.50%, and rapid eye movement 8.92±6.21%. Excessive fatigue or sleepiness, waking up tired, falling asleep during the day, trouble paying attention, snoring and insomnia were significantly related to decreased N3 sleep. Conclusions Most of the symptoms in OSAHS in adults are related to decreased stage N3 sleep. If confirmed by larger controlled studies, correcting N3 sleep deficiency by pharmacotherapy may become an important adjunct to CPAP/BIPAP therapy to alleviate symptoms.

Takotsubo cardiomyopathy precipitated by delirium tremens.

A 57-year-old woman presented with alcohol withdrawal symptoms, which later progressed to delirium tremens. During hospitalization, she developed respiratory distress with acute pulmonary edema. Electrocardiogram (ECG) showed diffuse ST elevation with elevated cardiac enzymes. Echocardiogram showed estimated ejection fraction of 20–25% with characteristic apical ballooning. After several days of supportive care, the patient showed significant clinical improvement with normalization of ECG, cardiac enzymes, and echocardiographic findings. Coronary angiogram revealed no coronary abnormalities. Although Takotsubo cardiomyopathy has been associated with diverse forms of physical or emotional stress, only a few cases have been described with delirium tremens in the medical literature.

Bilateral pneumothorax after bronchoscopy without biopsy--a rare complication: case presentation and literature review.

Bronchoscopy and bronchoalveolar lavage (BAL) are widely accepted diagnostic procedures in various pulmonary etiologies. Complications of bronchoscopy are relatively infrequent and most often minor, namely, bleeding and infection. Pneumothorax is a rare complication of bronchoscopy with transbronchial biopsy. Bilateral pneumothorax developing after BAL without biopsy has been rarely described in the literature. A 51-year-old woman presented with symptoms suggestive of reactive airway syndrome and underwent bronchoscopy with BAL to rule out vocal cord paralysis and to investigate other potential causes of her symptoms. Immediately after BAL, she developed bilateral pneumothorax requiring chest tube placement. The pneumothorax was resolved with the chest tube and the patient recovered. However, the etiology of the pneumothorax remained unclear. We presume that cough-related increase in intrathoracic pressure might have led to interstitial air dissection and bilateral pneumothorax.
