BACKGROUND: The purpose of this single case report was to report the use of anterior segment optical coherence tomography for the diagnosis and management of a retained vegetal intraocular foreign body. RESULTS: A 23-year-old otherwise healthy male presented with a progressive vision loss in the right eye (RE). He reported a mild ocular trauma with a tree leaf 1 year ago followed by recurrent episodes of redness and pain in the RE that partially resolved after a self-medication with topical steroids...

20 year old post renal transplant patient developed recurrent episodes of seizure. MRI revealed focal lesion in right parieto-occipital lobe with perilesional edema. FDG PET-CT revealed multiple hypermetabolic lesions in bilateral cerebral hemisphere. Subsequent biopsy from the lesion demonstrated bradyzoites of Toxoplasma gondii with inflammatory cells and thereby, a confirmatory diagnosis of cerebral toxoplasmosis was made. This case demonstrates the fact that increased FDG uptake in cerebral lesions in post transplant patient should be interpreted with caution and confirmed with histopathological correlation...

Activity-dependent processes are important to olfactory sensory neurons (OSNs) in several ways, such as cell survival and the specificity of axonal convergence. The identification of activity-dependent mRNAs has contributed to our understanding of OSN axon convergence, but has revealed surprisingly little about other processes. Published studies of activity-dependent mRNAs in olfactory mucosae overlap poorly, but by combining these agreements with meta-analysis of existing data we identify 443 mRNAs that respond to methods that alter OSN activity...

Neural mechanisms which bind items into sequences have been investigated in a large body of research in animal neurophysiology and human neuroimaging. However, a major problem in interpreting this data arises from a fact that several unrelated processes, such as memory load, sensory adaptation, and reward expectation, also change in a consistent manner as the sequence unfolds. In this paper we use computational simulations and data from two fMRI experiments to show that a host of unrelated neural processes can masquerade as sequence representations...

PURPOSE: To report a case of "posterior scleral melanocytosis," a pigmented lesion of the posterior sclera that clinically resembles a flat choroidal nevus. METHODS: Case report of a patient with posterior scleral melanocytosis. Multimodal imaging, including swept source optical coherence tomography, was used to demonstrate the scleral location of the pigmented lesion and to distinguish its features from a typical choroidal nevus present in the same eye. RESULTS: An 86-year-old woman was seen for regular follow-up for neovascular age-related macular degeneration in her right eye and 2 pigmented lesions in her left eye, both presumed to be choroidal nevi...

We report a case of ciprofloxacin-related drug rash with eosinophilia and systemic symptoms (DRESS) which was initially diagnosed and managed on the line of tropical fever. Later, a diagnosis of definite case of DRESS was made according to the RegiSCAR scoring system and the patient was managed with the removal of ciprofloxacin along with steroids. DRESS is a great masquerader. The diagnosis should be highly suspected in the presence of fever, skin rash, liver involvement, and hypereosinophilia.

Sarcoidosis is a multisystem disease of unknown etiology, developing granulomas in any tissues and organs. Approximately 25% of sarcoidosis patients have cutaneous involvement with various clinical manifestations, which are categorized into specific or nonspecific diseases based on the histopathology; the former represents the typical sarcoid granulomas. Subcutaneous sarcoidosis is one of the specific skin lesions and often affects extremities, to a much lesser extent with other anatomical sites. Herein, we report the case of an 82-year-old Japanese man with subcutaneous sarcoidosis whose skin nodules exclusively overlay the lines of superficial veins on the forearms...

The diagnosis and management of eyelid cancers are quite challenging. Eyelid tumours are relatively rare diverse group of diseases varied in their presentation and extent. Many benign tumours and inflammatory conditions quite frequently masquerade eyelid cancers. Eyelid cancers are not single entity but comprise a wide range of tumours with extremes of tumour biology from indolent to very aggressive histopathologic types. Compromise on aesthetics and eyelids' indispensable function of protecting the eyes during management, may lead to untoward cosmetic disfigurement and loss of vision...

Cervical pregnancy is a rare site of ectopic pregnancy compared to tubal. The trophoblast implant into the cervical tissue and become a potentially dangerous site of torrential haemorrhage. The widespread use of Ultrasonography (USG) has led to a dramatic increase in the detection rates of extra uterine pregnancy. We hereby report an interesting case of extra uterine pregnancy with a unique situation where only a high index of suspicion prevented an iatrogenic mishap. The patient was referred as a case of incomplete abortion with a documented report of minimal retained products...

BACKGROUND Primary care physicians and internal medicine specialists frequently encounter a variety of rashes. Many of these cases look and feel typical of common entities, resulting in the potential for misdiagnosis. CASE REPORT This is a case of a zosteriform rash where the surprising true diagnosis of metastatic melanoma was confirmed with bedside skin punch biopsy. Possible mechanisms involve direct cutaneous injury, neuronal, and dorsal root ganglia involvement in metastases. CONCLUSIONS Skin biopsy is indispensable especially when there is a lack of clinical response or deterioration in the clinical condition...

Attention deficit hyperactive disorder (ADHD), a hyperactivity disorder that is prevalent among children may continue as an adulthood attention deficit. To date, treating an individual with an adult ADHD may be an arduous task as it involved numerous challenges, such as a need for high index of suspicion to diagnose this medical condition. Many psychiatric disorders masquerade as ADHD and delayed the necessary assessment and proper treatment for the debilitating medical condition. Adult ADHD would also be misdiagnosed (or under diagnosed) due to the facts that this medical condition is being masked by his or her high level of intellectuality achievement...

The evaluation of prosthetic valves can provide a unique challenge, and a thoughtful approach is required. High output states like anemia should be kept in the differential when evaluating elevated gradients across prosthetic valves. We present the case of a 69-year-old man with a Starr-Edwards prosthetic aortic valve who presented with symptoms of congestive heart failure and high transvalvular pressure gradients. These symptoms indicate a potential prosthetic valve stenosis. His laboratory evaluation results were consistent with valve-related hemolysis...

Xanthogranulomatous pyelonephritis (XGPN) is an atypical long-term pyelonephritis with destruction of renal parenchyma and a long-term inflammatory infiltrate of macrophages. Reported presentations of transitional cell carcinoma (TCC) are different. A 73-year-old woman presented with loin pain, prostration, and fever. Computed tomography scan revealed poor cortical enhancement of the kidney, but some of the images bore resemblance to the characteristic "bear's paw" sign, consistent with XGPN with a 7-cm perinephric collection...

Tropical pulmonary eosinophilia (TPE) is an exaggerated immunological response to filarial antigens mainly seen in adults in endemic areas and is uncommonly reported in children. The diagnosis is frequently delayed as it mimics asthma clinically, while the chest radiograph might show miliary mottling which is often confused with that in pulmonary tuberculosis. A 5-year-old girl presented with episodes of nocturnal cough, wheeze, low grade fever and breathlessness for the previous 4 months and was being treated for asthma...
