This report describes a patient suffering from panic disorder who developed repeated suicidal ideation specifically due to the treatment with Venlafaxine. A first suicide attempt years ago occurred while being treated with Venlafaxine. Subsequent treatment with SSRIs or other antidepressants involved no suicidal ideation. Re-commencement of Venlafaxine four years later immediately led to a second suicide attempt. This unwanted effect subsided immediately after switching to another SNRI (i.e. Duloxetine). The case report underlines the importance of onset of suicide risk in panic disorders due to specific antidepressants.

Plasmodium falciparum infection is known to be associated with a spectrum of systemic complications ranging from mild and self-limiting to life-threatening. This case report illustrates a patient who had a protracted course in hospital due to several rare complications of falciparum malaria. A 21-year old man presented with a five-day history of high-grade fever, jaundice and abdominal pain and a two-day history of altered conscious state. A diagnosis of severe falciparum malaria was made based on the clinical presentation and a positive blood smear with parasitaemia of 45%. Despite adequate anti-malarial therapy with artesunate, the patient had persistent and worsening abdominal pain. Investigations suggested a diagnosis of acute pancreatitis, a rare association with falciparum malaria. However, in spite of supportive therapy for acute pancreatitis and a 10-day course of intravenous artesunate and oral doxycycline at recommended doses, he continued to be febrile with peripheral blood smear showing persistence of ring forms. Antimalarial therapy was, therefore, changed to quinine on the suspicion of possible artesunate resistance. On the 17th day of stay in hospital, the patient developed generalized tonic-clonic seizures. Computerized tomography of the brain showed bilateral fronto-parietal subdural haematomas that were surgically drained. His fever persisted beyond 30-days despite broad-spectrum antibiotics...

Quadrilateral space syndrome (QSS) is a rare condition in which the posterior humeral circumflex artery and the axillary nerve are entrapped within the quadrilateral space. The main causes of the entrapment are abnormal fibrous bands and hypertrophy of the muscular boundaries. Many other space-occupying causes such as a glenoidal labral cyst or fracture hematoma have been reported in the literature. However, we could not find a report on classical QSS caused by an osteochondroma. The aim of this case report is to attract attention to an unusual etiology of shoulder pain, and to emphasize the importance of physical examination and x-ray imaging before performing more complex attempts for differential diagnosing.

The increased morbidity and mortality resulting from respiratory failure in patients with neuromuscular disorders and/or kyphoscoliosis can be reversed with non-invasive ventilation. Spontaneous mode bilevel pressure ventilation is preferred to other modes of ventilation, due to relative ease of use, but may not be suitable for all patients. We report a 27-year old woman with Multi-minicore disease whose respiratory failure was refractory to spontaneous mode bilevel pressure ventilation. When we altered settings and provided mandatory inspiratory rise time and respiratory rate, it augmented her respiratory efforts and improved ventilation. Our case report describes the benefit of individualising non-invasive ventilation in the management of respiratory failure due to neuromuscular weakness and kyphoscoliosis.

In a patient undergoing regular hemodialysis through an arteriovenous fistula access, pleural effusion is a known long term complication. However, a unilateral hemothorax is relatively uncommon. Here we report a 46 year old male, end-stage renal disease patient, on maintenance hemodialysis, who presented with a giant brachiocephalic AV fistula in his left arm and progressive breathlessness. Radiological imaging revealed a left sided pleural effusion. Ultrasound guided aspiration revealed a hemorrhagic pleural fluid. A Doppler study of the fistula revealed a high velocity blood flow through the fistula, thereby establishing the cause of the unilateral hemothorax. Ligation of the fistula resulted in complete resolution of the hemothorax. The other possible causes for hemothorax in a dialysis patient are also discussed in this case report.

Minimally invasive investigations, such as pleural fluid cytological assessment and closed percutaneous pleural biopsy, are often performed first in the investigation of suspected malignant pleural effusions. Malignant pleural effusions can be diagnosed with pleural fluid cytology alone in most cases; however, closed pleural biopsy is performed to increase the diagnostic yield when pleural fluid cytology is negative. This additional yield is at the expense of increased complication rates. We report a 64-year old man with a negative pleural fluid cytology but suspected malignant pleural effusion who underwent a closed pleural biopsy, which was complicated by pneumothorax, pneumomediastinum and severe subcutaneous emphysema. Pulmonary laceration by the pleural biopsy needle is the most likely aetiology of these complications. Our case report highlights an infrequent but significant complication of closed percutaneous pleural biopsy.

The pelvic C-clamp traditionally is reserved for the temporizing stabilization of posterior ring injuries and reportedly has assisted in closed reduction of sacroiliac diastases, for patients who are in the supine position. We report a patient with a severely displaced Zone II sacral fracture and associated acetabular fracture who initially underwent fixation of the acetabulum in the prone position. By using the pelvic C-clamp as a tool for successfully reducing the sacrum, definitive closed fixation of the pelvic wing subsequently was performed without having to reposition the patient. In this case report, we review the literature on this device and for alternative reduction maneuvers for disrupted sacral injuries. The C-clamp may be a useful adjunct in select cases to facilitate closed reduction of sacral or sacroiliac joint disruptions, as may particularly apply in cases of severe displacement or when a reduction is hampered by obesity.

Pleural effusion that develops in a patient with cirrhosis and portal hypertension, in the absence of cardiopulmonary disease, is termed hepatic hydrothorax. Hepatic hydrothorax very rarely presents in the absence of ascites. Although the exact mechanism is somewhat controversial, pleural effusion occurs when ascitic fluid moves through diaphragmatic defects which are opened up by increased intra-abdominal pressure. We report a case report of cirrhotic pleural effusion in a patient with no clinical or radiographic evidence of ascites and discuss the pathogenesis, diagnosis and management of this condition.

The formation of fistulae is a recognised complication of diverticulitis. This case report describes sigmoid diverticulitis presenting as a right psoas abscess with a colocutaneous fistula. The report highlights the role of appropriate imaging and a high index of suspicion in anyone presenting with a discharging lumbar abscess, especially when the focus of infection may be from a contra-lateral source.

Purpose. To report on a patient with compressive optic neuropathy secondary to an Onodi cell mucocele, who fully recovered visual function following surgery. Method. Case report. Results. A 28-year-old male was admitted with a right visual acuity of 20/100 following treatment for an initial diagnosis of optic neuritis. Subsequent examination suggested compressive optic neuropathy, and neuroimaging confirmed the presence of an Onodi mucocele compressing the optic nerve. The patient underwent a right endonasal sphenoethmoidectomy with decompression 5 weeks after the initial onset of symptoms. Three weeks following surgery, the visual acuity was 20/20, and there was complete resolution of the visual field defect, which has remained stable at 1 year. Conclusion. Onodi cell mucocele should be included in the differential diagnosis of a young patient with compressive optic neuropathy. Surgical decompression should be considered even when symptoms have been present for over a month.

Purpose. To describe the successful use of dexmedetomidine as the primary procedural sedative for a percutaneous tracheotomy procedure and to systematically present the supporting literature. Materials and Methods. A Case report of our experience and systematic literature search. PubMed, Embase, and Google Scholar were searched without restriction using the key words dexmedetomidine, percutaneous tracheotomy, and tracheotomy procedure. All relevant published references were retrieved irrespective of their methodological quality. Results. In total, only 3 relevant references were found. These include one small placebo controlled randomized trial and 2 case reports. The randomized, placebo controlled trial enrolled patients already sedated on midazolam and included 64 total patients. The 2 other case reports both described the use of dexmedetomidine as the primary procedural sedative. All of the cases reported the successful completion of the percutaneous tracheotomy without any major complication, but none reported the subjective patient experience. Conclusion. Based on the available published literature and our experience, we suggest that dexmedetomidine be considered for use as the primary procedural sedative for percutaneous tracheotomy procedure. Dexmedetomidine's ability to provide adequate sedation and amnesia...

Diffuse large B-cell lymphomas (DLBCLs) are defined as neoplasms of large transformed B cells, i.e. with nuclear diameter more than twice that of a normal lymphocyte. These account for 30-40% of all adult non-Hodgkin's lymphomas (NHL). Intraoral lymphomas are relatively rare and often difficult to diagnose in clinical settings. In this case report, we describe a case of primary DLBCL affecting the anterior part of the hard palate of an elderly male patient. DLBCL of anterior part of hard palate is yet to be reported in the English literature, even though DLBCL cases involving the posterior palate have been recorded, thus making the present case to be first of its kind. Emphasis has also been given on the subclassification, differential diagnosis and prognostic antibody factors determining the outcome of DLBCL.

Background. Vitamin B12 is vital for optimal functioning of various organ systems but more importantly the central nervous system and the hematological system. Deficiency of vitamin B12 clinically manifests as excessive daytime fatigue, memory difficulties, encephalopathy, myelopathy, peripheral neuropathy, and optic neuropathy. In occupational medicine, vitamin B12 deficiency has been reported with exposure to nitrous oxide in health care workers. However, not much is known about exposure to Freons in other industries and vitamin B12 deficiency. Aim. We are reporting a case of vitamin B12 deficiency in the setting of exposure to chlorofluorocarbon (CFC) gases. Case Report. A 55-year-old male refrigerator mechanic experienced recurrent visual symptoms, which included diplopia and blurring. A complete workup was done and was significant of vitamin B12 deficiency. However, his B12 levels were refractory to supplementation. Appropriate precautions at workplace improved patient's symptoms and were associated with significant improvement in B12 levels. Conclusion. To the best of our knowledge, this is the first reported case of vitamin B12 deficiency (that remains refractory to supplementation) in the setting of exposure to Freon gases.

Background. Acral lentiginous melanoma (ALM) is a less-common form of melanoma in US, and it accounts for about 5% of all diagnosed melanomas in US. ALM is often overlooked until it is well advanced because of the lesion's location and its atypical appearance in the early stages. We present a case of ALM initially presented as a diabetic foot ulcer. Case Report. An 81-year-old man initially presented to the primary care clinic with a right foot diabetic ulcer. There was a large plantar, dark-colored ulcer that bled easy. Initial excision biopsy revealed Clark's Level IV ALM. Subsequent definitive wide excision and sentinel node biopsy confirmed ALM with metastasis to inguinal lymph nodes (stage IIIb). The treatment included wide margin excision of the lesion with en bloc amputations of 4th and 5th toes, followed by adjuvant chemotherapy. Discussion. The development of ALM may potentially relate to diabetes as a reported higher prevalence of diabetes with ALM patients. Conclusion. The difficulty in early diagnosing of ALM remains as a formidable challenge particularly in diabetic patients who commonly develop plantar foot ulcers due to the diabetic neuropathy. This case reiterates the importance of a thorough foot exam in such patients.

This case report exhibits a rare biliary tumor within the liver of a 53-year-old Caucasian woman. This exophytic, multicystic, 6.5 × 5.0 cm mass was composed of complex tubulocystic structures lined by nonmucin-secreting, biliary epithelium embedded in fibrous stroma, consistent with biliary adenofibroma. This is the seventh case described in the literature. Multiple foci of high-grade dysplasia/carcinoma in situ were found with a microscopic focus of invasive carcinoma in review of the pathology, making this only the second case reporting malignant transformation. It is presented to illustrate the premalignant potential in a biliary epithelial tumor currently categorized as benign.

Symptomatic neurosyphilis (NS) can have varied syndromic presentations: Meningitis, meningovascular and parenchymatous involvement. Non-tabetic syphilis affecting the spinal cord is rare and only sporadic case reports have been published. The variant of meningomyelitis known as Erb's paraplegia refers to patients of spinal syphilis with very slow progression over many years and predominantly motor signs. Primary optic atrophy occurs twice as frequently in tabes dorsalis as in other types of NS. We describe here a case of a 32-year-old truck driver who presented with Erb's paraplegia with primary optic atrophy. This clinical overlap in NS is extremely rare and to our knowledge is the first case report of its type.

The variability of root canal system morphology presents a continuous challenge to endodontic diagnosis and therapeutics. There have been reports of teeth with multiple roots and canals as also those with lesser number of root and root canals. Variations of root canal systems need not always be in the form of extra canals. Clinicians should be aware that there is a possibility of existence of fewer numbers of roots and root canals than normal, which presents varied canal anatomy and poses a challenge to the clinician's expertise. This case report deals with the management of an unusual case of C-shaped canal in mandibular molar with two buccally fused roots. Cone-beam computed tomography (CBCT) was employed to confirm the extension of the unusual anatomy. The Self Adjusting File (SAF) system was used to ensure complete cleaning of the canal system. One-year follow-up of the case showed good healing. The clinician should expect to encounter unusual features when performing endodontic treatment. Use of diagnostic aids like CBCT, improved magnification with dental operating microscope, and the use of novel file systems like SAF ensure success.
