Description of two cases of infectious keratitis in patients after Boston Type 1 keratoprosthesis (Boston KPro) implantation. The first case refers to a patient that had the device indicated due to limbal deficiency secondary to severe dry eye who presented a fungal infection by Aerobasidium pullulans that was successfully treated with amphotericin B eye drops. The second case reports a patient with Boston KPro implantation due to previous corneal transplant rejection showing bacterial keratitis in the fourth postoperative month. The etiologic agent was identified asStreptococcus sp and topical treatment with vancomycin was effective. The importance of postoperative surveillance in Boston KPro eyes is discussed.

A new technique for the treatment of diplopia secondary to cosmetic botulinum toxin A use is described. In this interventional case reports, two consecutive patients who developed diplopia after periocular cosmetic use of botulinum toxin A were treated with intramuscular botulinum toxin A injection into the antagonist extraocular muscle. Diplopia resolved in both patients in less than 1 week with no side effects or complications. In conclusion, the injection of intramuscular botulinum toxin A is an encouraging option for treatment of diplopia secondary to botulinum toxin A use for facial lifting.

Cat-scratch disease warrants extensive investigation, from an epidemiological, a diagnostic, but especially a therapeutic point of view. Two suggestive episodes of Bartonella henselae-caused cat-scratch disease are reported, and discussed in the light of the most recent literature evidence. The first case occurred in a 60-year-old man, thus suggesting that it is important to maintain an elevated level of suspicion for this disease in adults as well. Both episodes were characterized by a very prolonged and complicated disease course (with the involvement of three lymph node sets in the first case), a need for lymph-node drainage, and apparently negligible activity of many antimicrobial courses, with a very slow local cure. While specific culture and molecular biology techniques proved negative (probably due to late availability of appropriate clinical specimens), indirect immunofluorescence antibody assay was positive since the first weeks of disease, and elevated levels were also fond many months after disease onset. When clinicians face patients with prominent swelling of lymph nodes draining from the upper limbs, cat-scratch disease may be suspected on the grounds of epidemiological and clinical features, with a limited systemic involvement contrasting with a prominent local disease. The significance of specific antibody temporal kinetics in the subacute disease course is still unknown. Although biomolecular assays are now available...

Parathyroid carcinoma is a rare malignancy, and only accounts for 0.5–2% of cases of primary hyperparathyroidism. Less than 10% of parathyroid carcinomas are non-functional, and as such, they have been rarely reported in the literature. Importantly, margin status at resection is related to prognosis, and only a handful of case reports of non-functional carcinoma note this important parameter. Here we report the first case of non-functional parathyroid carcinoma with negative margins, and review the literature on this rare entity. Whether functional or non-functional, parathyroid carcinoma can often be difficult to differentiate from benign parathyroid adenoma. While diagnosis has been based on clinical and histological criteria, recent data concerning the molecular underpinnings of parathyroid carcinoma may allow for improved accuracy in distinguishing benign and malignant parathyroid tumors.

The aim of this study was to describe clinicopathologic and radiographic features of two cases of schwannoma involving the oral tongue and to review the literature of this unusual clinical entity. Case reports with review of the pathologic, radiologic and clinical data for two patients with schwannoma of the tongue are reported. Review of the literature of case reports of schwannomas (neurilemmomas) of the tongue from 1955 to 2006 with analysis of the patient’s age, gender, presenting symptom(s), tumor size, and surgical approach was undertaken. The two patients in our series presented with painless swelling of the tongue. Transoral excision was performed and pathologic examination confirmed the diagnosis of schwannoma in both the cases. A total of 126 cases of schwannoma of the tongue have been reported in the English literature over the past 51 years. Schwannomas of the tongue typically present in the third decade of life (33%), display no gender predilection (52.8% female; 47.2% male) and often present as a painless mass (69.6%). Schwannomas are likely to elicit distressing symptoms when they occur in the posterior one-third of the tongue (63.2 vs. 13.5%) or approach 3 cm in greatest dimension (33.0 vs. 18.2 mm). The vast majority of cases have been treated with transoral excision (94.8%). Recurrence after surgical excision has not been reported. Schwannoma of the tongue is a relatively rare tumor of the head and neck. Transoral resection allows for removal of this tumor in a manner that precludes recurrence...

The purpose of presenting these case reports is to highlight the occurrence of heterotopic glial tissue of the tongue and nose in children. So far, literature review has revealed few case reports of such lesions in neonates, but our patients presented with this unique lesion at the age of two and a half years and 3 years. This is a rare congenital anomaly in the tongue, which can mimic a lingual thyroid, teratoma, dermoid cyst etc. Surgical excision is mandatory when the lesion causes obstructive symptoms. The authors discuss the problems in diagnosis, pathology and management and review the literature.

Streptococcus salivarius is a normal member of the human oral microbiome that is an uncommon cause of invasive infections. Meningitis is a rare but increasingly reported infection caused by S. salivarius. Despite the growing number of reported cases, a comprehensive review of the literature on S. salivarius meningitis is lacking. We sought to gain a better understanding of the clinical presentation, evaluation, management, and outcome of S. salivarius meningitis by analyzing previously reported cases. In addition to a single case reported here, 64 previously published cases of meningitis were identified for this review. The collected data confirm that most patients presented with classical signs and symptoms of bacterial meningitis with a predominance of neutrophils in the cerebrospinal fluid (CSF) and hypoglycorrhachia. The majority of cases followed iatrogenic or traumatic CSF contamination. Most cases were diagnosed by CSF culture within one day of symptom onset. There was no clear evidence of predisposing co-morbid conditions in patients with meningitis, although in most case reports, limited information was given on the medical history of each patient. Outcomes were generally favorable with antibiotic management. Clinicians should suspect S. salivarius meningitis in patients presenting acutely after medical or surgical procedures involving the meninges.

Case histories of two unrelated patients suffering from sensory ataxic neuropathy, dysarthria/ dysphagia and external ophthalmoplegia (SANDO) are reported. Both patients showed compound heterozygosity for POLG1 gene mutations, and presented with symptom of the clinical characteristics of SANDO. A patient with a p.A467T and p.W748S, well-known mutations showed a progressive course with early onset and multisystem involvement, including symptoms characteristics for mitochondrial neurogastrointestinal encephalomyopathy (MNGIE). The second patient showed a less well-known p.T251I and p.G848S mutations with late onset and dysphagia/dysarthria dominated, moderate symptoms. This later is the second published case history, when these POLG1 gene mutations are the possible background of late onset SANDO, dominantly presenting with bulbar symptoms.

Conventional root canal treatment (RCT) of the teeth has long shown high success rate. However, the endodontic treatment of a pulpless tooth with periapical radiolucency of a considerable size always has a question of success. In modern days, surgical exploration is avoided, especially in the posterior teeth. These types of cases may be successfully managed by orthograde Mineral Trioxide Aggregate (MTA) placement in the apical third of the root followed by proper obturation. The objective of our present case reports was to evaluate the periapical pathology of posterior teeth clinically and radiographically by using MTA in orthograde way and avoiding traumatic surgical exploration. In the first case, the patient reported with intraoral sinus and pus discharge related to tooth #45. On radiograph, open apex (blunderbuss) was found along with periapical radiolucency. In the second case, the patient reported with pain and swelling related to tooth #26, having large periapical radiolucency related to the palatal canal. On vitality test, both the teeth responded negative, i.e., non-vital. Conventional RCT was planned in both the cases with orthograde MTA- Angelus (Angelus, Londrina, PR, Brazil) apical plug followed by the proper obturation with gutta-percha (G.P.)...

Taurodontism is a morphoanatomical developmental anomaly rarely seen in teeth. Permanent mandibular molars are most commonly affected. Endodontic treatment of a taurodont tooth is challenging and requires special handling because of proximity and apical displacement of roots. This paper presents a successful endodontic therapy of all three types of taurodonism with two case reports - the first case with mesotaurodontism of mandibular left first molar and hypotaurodontism of mandibular left second molar and the second case with hyper taurodontism of mandibular left second molar.

Tumor-to-tumor metastasis is a clinical entity that has been documented in medical literature as early as the 1900s. It is rare and published primarily as case reports, although its incidence seems to be on the rise as a result of improving medical care in developed countries. We report an unusual case of metatstatic breast tumor to a benign renal tumor, in a patient with a remote history of breast cancer. This case reinforces in our minds the enigmatic nature of breast cancer and its wide spectrum of clinical behavior.

Metaplastic breast cancers (MPBCs) represent <1% of breast cancers. Reports of MPBC in men are limited to case reports. We report a case of MPBC with pulmonary metastasis occurring in a 59-year-old man who initially presented with a presumed breast abscess. Histology from the breast lesion revealed a poorly differentiated carcinoma and a computed tomography scan showed an ulcerative right-sided breast mass and an area of scarring in the apex of the left lung. The breast lesion and the lung lesion were resected separately and the histology from the lung showed a poorly differentiated carcinoma with sarcomatous features in keeping with metastasis from a primary breast cancer. Our patient then proceeded to chemotherapy with FEC 100 regimen (5-fluorouracil, epirubicin and cyclophosphamide). MPBC is an aggressive breast cancer that has a propensity to metastasis to the lungs. Prognosis is poor.

Injuries to the inferior vena cava (IVC) secondary to blunt trauma are rare and occur in only 1–10% of all blunt trauma patients. Management of these injuries has not been subjected to major studies, but several case reports and small retrospective studies have demonstrated that management can be tailored to the hemodynamic status of the patient; this is similar to the management of blunt liver injuries. Stable patients whose injuries have achieved local venous tamponade have been successfully treated without surgical intervention, while unstable patients require operative management. Regardless of patient status, however, IVC injuries are highly fatal with mortality rates between 70 and 90%. This report describes the case of a patient with a blunt traumatic injury to the supradiaphragmatic IVC with development of a pseudoaneurysm who was successfully managed conservatively.

Nontyphoidal Salmonella, especially Salmonella enterica, is a rare cause of endocarditis and pericarditis that carries a high mortality rate. Proposed predisposing conditions include immunodeficiency states, congenital heart defects, and cardiac valve diseases. We present 2 cases of cardiovascular salmonellosis. The first case is that of a 73-year-old woman with mechanical mitral and bioprosthetic aortic valves who died from sequelae of nontyphoidal Salmonella mitral valve vegetation, aortic valve abscess, and sepsis. The second case is that of a 62-year-old man with a recent systemic lupus erythematosus exacerbation treated with oral steroids, who presented with obstructive features of tamponade and sepsis secondary to a large S. enteritidis purulent pericardial cyst. He recovered after emergent pericardial drainage and antibiotic therapy. Identifying patients at risk of cardiovascular salmonellosis is important for early diagnosis and treatment to minimize sequelae and death. We reviewed the literature to identify the predisposing risk factors of nontyphoidal Salmonella cardiac infection.

The aim of this article is to emphasize that the accidental displacement of a lower third molar during extraction is a rare, but potentially serious complication. We present two case reports on a lower third molar tooth dislodged into the submandibular space following its removal from the sockets and the subsequent management of this rare complication. Differences in the direction of displacement, the size of fragment, delay in retrieval, and tissue reactions can all influence this potential serious complication and hence no one technique is uniformly applicable. Though a rare complication, clinicians must be aware of possible lower third molars dislodgement into tissue spaces and the necessity to initiate prompt and appropriate management.

Ultrasound-guided cannulation of a central venous catheter into the internal jugular vein (IJV) was performed in the intensive care unit for a critically ill patient. The catheter was inserted into the subclavian artery distally, despite prior ultrasound confirmation of the guidewire position using both the in-plane and out-of-plane views. The catheter was removed successfully by the interventional radiologist with a closure device. To our knowledge, there have been previous case reports of subclavian artery injury during IJV cannulation with ultrasound guidance, but rarely in the setting whereby the guidewire was visualized before dilatation and railroading of the catheter. This case demonstrates that the confirmation of the guidewire in the proximal segment of the vein is insufficient to exclude arterial cannulation.

Meningiomas represent 3 to 12% of the tumors that involve the cerebellopontine angle and internal auditory canal (IAC). Intracanalicular meningiomas, however, are rare. Only 10 well-documented cases have been reported in the English literature. The differential diagnosis includes acoustic neuromas, facial nerve neuromas, hemangiomas, lipomas, and meningiomas. We report two new cases of intracanalicular meningioma. Both patients had unilateral tinnitus. In case 1, the patient also experienced sensorineural hearing loss with unilateral tinnitus. In case 1, the lesion appeared hyperintense on T1-weighted and hypointense on T2-weighted magnetic resonance images. In case 2, the patient had an enhancing lesion in the right IAC. The tumors were moderately cellular, and meningeal whorls and meningothelial inclusions were present. Immunohistochemical staining revealed the tumors to be positive for epithelial membrane antigen (EMA) and negative for S-100 protein. The radiologic findings that help distinguish a meningioma from other lesions are reviewed.

Thrombosis during HIV infection was commonly vein thrombosis. Arterial thrombosis is also more and more described. We report two cases detected in the Abidjan Cardiology Institute. Case Reports. Case 1: an HIV infected female presented with sudden loss of consciousness and right hemiplegia. She had been taking HAART regimen for five years. Neck vessels ultrasonography revealed thrombosis on left ICA. Anticoagulant treatment leads to reduction of symptoms and left ICA partial recanalization. Case 2: male HIV infected taking HAART therapy was admitted for an acute pain of left lower limb; examination showed a decrease of heat, sensitivity, and mobility of this limb with popliteal and tibial pulses abolished. Arterial ultrasonography and CT angiography showed occlusion on the lower third of superficial femoral artery and homolateral popliteal artery suggesting a thrombosis of this artery. He underwent a femorotibial bypass surgery and anticoagulant treatment. The outcome was good with reappearance of local heat of the limb and tibial pulses. Probable etiology is early carotid atherosclerosis associated with protein S deficiency in the first case and antiphospholipid syndrome in the second case. Conclusion. Arterial thrombosis might occur in HIV infection. Several etiological factors could be involved in the pathogeny of these arterial thromboses.
