The role of bone scintigraphy in the assessment of chronic wrist pain without any trauma history

Bone scintigraphy of the hands and wrists represents an important adjunct imaging technique that complements plain film radiographic examination in the evaluation of chronic wrist pain. In this study, the effectiveness of bone scintigraphy was investigated in the evaluation of chronic wrist pain in the patients without the history of trauma and any radiological and rheumatological abnormalities. Seventy-one patients with normal conventional radiographs and unexplained wrist pain were evaluated prospectively between 1998 and 2003 in our hand surgery clinic. There was no trauma history and no specific physical examination findings in the patients. The bone scintigraphy was done in all patients. Fifty-two of the all patients had normal scintigram. Seventeen of the remaining 19 patients showed increased activity over triquetrum (5 cases), lunatum (4 cases), trapezium (4 cases), hamatum (2 cases) and psiforme (2 cases). As the additional radiological investigations like MRI and CT revealed no bony abnormalities, the results of bone scintigraphy were evaluated as chronic ligamentous injuries. Two patients had diffuse increased uptake compatible with synovitis. The evaluation of bone scintigraphy correlated with clinical findings is effective to choose the most efficient treatment method in chronic wrist pain.     

Cerebellar abscess and syringomyelia due to isoniazid-resistant Mycobacterium tuberculosis.

A 19-year-old immunocompetent man was admitted to hospital with diplopia, nausea, vomiting and change in mental status. The patient had a history of tuberculous meningitis that was diagnosed at another hospital 6 months before the present admission, and at that time anti-tuberculosis treatment was initiated using a first-line drug combination. A computed tomography (CT) scan of the brain revealed non-communicating hydrocephalus. A ventriculo-peritoneal shunt was inserted surgically. Two months later, the patient was hospitalized again for fever, dysphagia and left hemiparesis. At that time, his cranial CT findings were within normal limits; however, magnetic resonance imaging (MRI) revealed an irregular multilocular peripheral contrast-enhancing lesion in the posterior fossa. The abscess was surgically drained. The presence of acid-fast bacilli in the abscess material was demonstrated by Ziehl-Neelsen staining. Mycobacterium tuberculosis grew on Lowenstein-Jensen culture medium, and the strain was found to be resistant to isoniazid. One month after the operation, the patient became quadriparetic. Cervical MRI revealed a cervico-thoracic syringomyelitic cavity, after which a syringoperitoneal shunt was placed. Treatment with four drugs was continued for 10 months, and then treatment with three drugs for a total period of 18 months. The patient recovered, with residual quadriparesis. Even though very rare, isoniazid-resistant M. tuberculosis may be the causative agent of progressive tuberculosis.     

Systemic lupus erythematosus and thrombotic thrombocytopenic purpura: a case report.

BACKGROUND: Thrombotic thrombocytopenic purpura (TTP) is a multisystem disorder characterised by platelet aggregation causing microvascular occlusion. Early diagnosis and utilization of plasmapheresis can provide an improvement in prognosis. CASE REPORT: A 17 year old male with classical findings of TTP was later diagnosed as systemic lupus erythematosus (SLE). Plasmapheresis resulted in the significant amelioration of the course. CONCLUSION: The coexistence of TTP and SLE may facilitate a better understanding of in the pathophysiology of TTP. These association may provide the role of autoimmunity in TTP. SLE should be considered in the differential diagnosis of patients with TTP because of therapeutic implications.     

Comparison of patient satisfaction,quality of life,and bite force between elderly edentulous patients wearing mandibular two implant‐supported overdentures and conventional complete dentures after 4 years

This study compared two groups of patients who were elderly and edentulous, one group included subjects who had mandibular overdentures supported by two implants (Group I); the other groups wore conventional complete dentures (Group II). This retrospective study included 100 edentulous patients (50 from each group) with an average age of 67.86 years, who had been followed for 4 years. The groups were compared in terms of patient satisfaction, quality of life (QOL), and bite force. The bite force and patient satisfaction scores of Group I were found to be statistically significantly higher than Group II (p < .05). However, no statistically significant difference was found between the two groups’ QOL scores (p > .05) except on the physical pain subscale (p = .013). Based on these results, it can be concluded that after 4 years of function, subjects wearing mandibular overdentures supported by two implants had higher values for bite force and patient satisfaction scores, but similar QOL scores when compared to conventional complete denture‐wearers.     

Ocular complications of severe corneal abrasions after cosmetic blepharopigmentation

A 53-year-old woman with hemiparesis and poor dexterity, underwent cosmetic blepharopigmentation on the both upper eyelids in the dermatology clinic of a private hospital. She was not asked for any information on her medical history and no informed consent was obtained and the procedure was performed without any protective ocular shields. The patient experienced severe lacrimation, discomfort, and increased sensitivity to light during and after the procedure. She also noticed blurred vision after the procedure. Ophthalmologic examination revealed tender and oedematous eyelids and corneal abrasions in both of her eyes. Topical antibiotics and preservative-free lubricants were able to recover her from her signs and symptoms at 1-week follow-up. It is recommended that cosmetic blepharopigmentation should be applied cautiously with patient’s informed consent after obtaining a thorough medical history and with protective ocular shields to avoid potential complications.     

A rare complication of mechanical aortic valve replacement: Separation in the region of the mitral‐aortic intervalvular fibrosa

A 28‐year‐old man was admitted to our emergency service with a shortness of breath and palpitation. On admission, his blood pressure was high and he was in hypertensive pulmonary edema. His physical examination showed rales in both lungs and pansystolic murmur at mitral focus. His medical history included aortic valve replacement (AVR) because of native aortic valve infective endocarditis. Transthoracic echocardiography (TTE) showed normal functional aortic valve. Color flow imaging demonstrated severe mitral regurgitation with posterior eccentric jet. To examine in detail, transesophageal echocardiography (TEE) and three‐dimensional (3D) echocardiography were performed. TEE disclosed a separation in the subaortic curtain leading to severe mitral regurgitation from the left ventricle to the left atrium. In addition to severe mitral regurgitation with posterior eccentric jet, 26‐mm‐long pouch was seen in mitral‐aortic intervalvular fibrosa (MAIVF) at 120° TEE view. This pouch was separated from the mitral anterior leaflet junction releasing the mitral anterior leaflet and causing prolapse and chorda rupture in the A2 scallop of the mitral anterior leaflet. The MAIVF connects the anterior mitral leaflet to the posterior portion of the aortic annulus. The separation of the MAIVF represents a complication of the aortic valve replacement.
