#1
Muhammad Shafiq, Yousaf Zafar
Acute acalculous cholecystitis (AAC) is most commonly seen after surgery in critically ill patients. Early diagnosis and treatment is the key in the management of AAC. Ultrasound is the commonly used first modality for right upper quadrant (RUQ) pain with sensitivity equal to or greater than 80% for AAC. Computed tomography (CT) scan is reported to have a sensitivity close to 90% and if both the ultrasound and CT scan are combined, it further increases the sensitivity for the diagnosis of AAC. It is unlikely for AAC to be present in the setting of both negative ultrasound and CT scan of the abdomen...

Mohtar Ibrahim, Jin Yi Yap
We describe the first clinical case of Burkholderia cepacia keratitis registered in Southeast Asia. A man in his mid-70s with underlying poorly controlled diabetes mellitus came with complaints of painful red left eye for 4 days. This was accompanied with photophobia and blurring of vision after being injured by a wooden particle while cutting grass. Slit-lamp examination showed a paracentral anterior corneal stromal infiltrates with overlying epithelial defect. Culture of the corneal smear isolated B. cepacia that was sensitive to ceftazidime, meropenem and bactrim (trimethorprim and sulfomethoxazole)...

Concurrent Pneumocystis jirovecii (PJ) and pulmonary histoplasmosis (PHP) are rare in a single HIV individual. We present a challenging case of concomitant PJ and PHP in a young HIV individual. A 44-year-old man presented to the emergency department with progressive pulmonary symptoms. He was hypoxic with bilateral pulmonary opacities on chest radiograph. CT of the chest showed a geographical pattern of ground-glass attenuation. He started receiving intravenous antibiotics in addition to oral Bactrim for suspected PJ...

Nocardiosis is a rare but severe infection caused by bacteria of the genus nocardia, which belong to the order actinomycetales. If they can affect immunocompetent adult, nocardioses are pathologies affecting the individuals with weakened immune system. Pulmonary involvement is the most common manifestation, its correct management is based on diagnosis, which is often delayed due to non-specific symptoms and inconclusive specimens. We here report two cases of nocardiosis in immunocompetent patients. The first case concerns a 24-year old man with a history of smoking and alcoholism, hospitalized for chest pain and hemoptysis of low abundance evolving for two months, associated with the occurrence of dorsal subcutaneous fistulized abscess...

History A 35-year-old man from the upper Midwest region of the United States who had no relevant medical history initially presented to an acute care clinic with multiple small tender skin lesions. His temperature was 38.1°C, and physical examination revealed several small fluctuant masses that were draining purulent material. Skin culture of one of the draining lesions was performed at this time, but there was no subsequent bacterial growth. A diagnosis of furunculosis was made, and Bactrim (sulfamethoxazole-trimethoprim; AR Scientific, Philadelphia, Pa) and a regimen of chlorhexidine washes were prescribed...

Post-transplant immunosuppression is necessary to prevent organ rejection. Immunosuppression itself can introduce complications arising from opportunistic infections. We present a case of disseminated blastomycosis manifested only as a skin lesion in an asymptomatic patient post-orthotopic heart transplantation. A 64-year-old female who had recently undergone orthotopic heart transplant for end-stage ischemic cardiomyopathy presented for a scheduled routine cardiac biopsy. The patient had no current complaints other than a crusted plaque noticed at her nasal tip...

INTRODUCTION: Nocardia sinusitis is exceptional, as a Medline search revealed only one published case. The authors report a case of sphenoid sinusitis complicated by infratemporal fossa abscess, which raised several diagnostic problems. CASE REPORT: The patient was referred with temporal headache, subacute trigeminal neuralgia and subsequent infectious syndrome. Computed tomography imaging revealed left sphenoid sinusitis with osteolysis and infratemporal fossa abscess, as well as suspicious lung nodules suggestive of the initial site of infection...

While antifolates such as Bactrim (trimethoprim-sulfamethoxazole; TMP-SMX) continue to play an important role in treating community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), resistance-conferring mutations, specifically F98Y of dihydrofolate reductase (DHFR), have arisen and compromise continued use. In an attempt to extend the lifetime of this important class, we have developed a class of propargyl-linked antifolates (PLAs) that exhibit potent inhibition of the enzyme and bacterial strains...

PURPOSE: We performed a literature synthesis to identify the full spectrum of compounds implicated in drug-induced, bilateral secondary angle-closure glaucoma (2° ACG). METHODS: Systematic PubMed literature review identified relevant bilateral 2° ACG case reports. We evaluated these reports with both the Naranjo adverse drug reaction probability scale to assess the causality of reported drug reactions and a 2° ACG scale scoring system we developed to determine the likelihood that the event represented bilateral 2° ACG...

Nieves Perdigones, Mariela Morales, Philip Mason, Monica Bessler
We describe a case of paroxysmal nocturnal hemoglobinuria (PNH) in a woman who is heterozygous for the glucose-6-phosphate dehydrogenase A-   ( G6PDA-) allele. PNH is associated with one or more clones of cells that lack complement inhibition due to loss of function somatic mutations in the PIGA gene.  PIGA encodes the enzyme phosphatidylinositol glycan anchor biosynthesis, class A, which catalyses the first step of glycosylphosphatidylinisotol ( GPI)  anchor synthesis. Two GPI anchored red cell surface antigens regulate complement lysis...

BACKGROUND: Acute porphyria and Arnold Chiari malformation are both uncommon genetic disorders without known association. The insidious onset, non-specific clinical manifestations, and precipitating factors often cause diagnosis of acute porphyria to be missed, particularly in patients with comorbidities. CASE REPORT: A women with Arnold Chiari malformation type II who was treated with oxybutynin and antibiotics, including Bactrim for neurogenic bladder and recurrent urinary tract infection, presented with non-specific abdominal pain, constipation, and diarrhea...

INTRODUCTION: Immunodeficiency can occur both in patients undergoing radiation therapy, as well as in patients who have had thymectomies. However, few studies have examined the immune recovery of a patient following both procedures. We aim to emphasize the need for assessment and consistent monitoring of patients with thymoma prior to and after combined treatment of thymectomy and radiation, both of which are likely to result in an increased risk for immunodeficiency. CASE PRESENTATION: We describe the longitudinal progress of a 59-year-old Asian male who underwent thymectomy followed by radiation therapy and subsequently presented with generalized urticaria...
