A female patient, aged 61 years, presented to us with a 3-day history of fever and altered sensorium. She was discharged from another hospital 1 week back where she was admitted for community-acquired pneumonia. She was put on mechanical ventilation for threatened airway and her magnetic resonance brain imaging showed evidence of delayed posthypoxic leucoencephalopathy, also known as Grinker’s myelinopathy. She was discharged 1 month later, on room air with a tracheostomy tube in situ. On follow-up after 5 months, she was ambulating with support and carried out activities of daily living independently.

Dandy–Walker syndrome associated with syringomyelia is a rare condition, with few reports of adult cases. We describe an adult case of Dandy–Walker syndrome with concomitant syringomyelia. A 33-year-old man presented with a 3-month history of walking instability, numbness in the hands, memory deterioration, and urinary incontinence. A physical examination showed a positive Romberg sign. Brain computed tomography and magnetic resonance imaging showed hydrocephalus, a cyst in the posterior fossa, absence of the cerebellar vermis, hypoplasia of the corpus callosum and cerebella, and syringomyelia. All of these symptoms were consistent with the diagnosis of Dandy–Walker syndrome. Surgery involving arachnoid adhesiolysis and endoscopic third ventriculostomy was performed. At the 6-month follow-up, the symptoms were completely relieved. Magnetic resonance imaging showed that syringomyelia was greatly reduced and the hydrocephalus remained unchanged. Dandy–Walker syndrome with concomitant syringomyelia in adults is exceedingly rare. Early diagnosis and appropriate surgical treatment of this condition should be highlighted. Combined arachnoid adhesiolysis and endoscopic third ventriculostomy may be an effective approach.

Diffusion-weighted (DW) MR imaging usually identifies acute cerebral infarction injury in symptomatic patients. We report a patient with severe hypoxic brain injury following suicide attempt by hanging, but with normal DW MR imaging 5–6 h after the event. Follow-up DW MR imaging 3 days after the event, and subsequent autopsy, revealed extensive cerebral anoxic injury.

Ductal carcinoma in situ in men is incredibly rare and detection by conventional mammography and ultrasound is often challenging. We report an unusual case of a 50-year-old male, with no family history of breast cancer, who presented with an 8-year history of left-sided breast pain and recurrent bloody nipple discharge without any significant suspicious imaging features in mammography and targeted high-resolution ultrasound. Breast magnetic resonance imaging was performed as an adjunct modality. Magnetic resonance imaging findings revealed a suspicious retroareolar non-mass abnormality of segmental, linear and dendritic pattern, which was highly suspicious for a ductal carcinoma in situ. Stereotactic guided biopsy and subsequent mastectomy were consistent with pure high-grade ductal carcinoma in situ of the left breast. Overall, this case highlights the challenges in diagnosing ductal carcinoma in situ in men and demonstrates the importance for further investigating clinical suspicions of the male breast.

Abstract Stereotactic radiosurgery has been shown to treat successfully angiographically demonstrated arteriovenous malformations of the brain. Angiographic obliteration has represented cure and eliminated the risk of future hemorrhage. The role of radiosurgery in the treatment of angiographically occult vascular malformations (AOVMs) has been less well defined. In the initial 32 months of operation of the 201-source cobalt-60 gamma knife at the University of Pittsburgh, 24 patients meeting strict criteria for high-risk AOVMs were treated. Radiosurgery was used conservatively; each patient had sustained two or more hemorrhages and had a magnetic resonance imaging-defined AOVM located in a region of the brain where microsurgical removal was judged to pose an excessive risk. Venous angiomas were excluded by performance of high-resolution subtraction angiography in each patient. Fifteen malformations were in the medulla, pons, and/or mesencephalon, and 5 were located in the thalamus or basal ganglia. Follow-up ranged from 4 to 24 months. Nineteen patients either improved or remained clinically stable and did not hemorrhage again during the follow-up interval. One patient suffered another hemorrhage 7 months after radiosurgery. Five patients experienced temporary worsening of pre-existing neurological deficits that suggested delayed radiation injury. Magnetic resonance imaging demonstrated signal changes and edema surrounding the radiosurgical target. Dose-volume guidelines for avoiding complications were constructed. Our initial experience indicates that stereotactic radiosurgery can be performed safely in patients with small, well-circumscribed AOVMs located in deep, critical, or relatively inaccessible cerebral locations. Because cerebral angiography is not useful in following patients with AOVMs, long-term magnetic resonance imaging and clinical studies will be necessary to determine whether the natural history of such lesions is changed by radiosurgery.

This paper reviews the clinical and radiographic features and treatment results in eight patients with intraosseous epidermoid cysts in the terminal phalanx of a finger seen over a period of 26 years. Data on age, sex, occupation, diagnostic findings, history of injury in six cases, treatment and follow-up were obtained by reviewing medical records and the histopathological findings using the hospital database. The most frequent symptoms of pressure pain, tenderness, redness and swelling occurred at a median time of 12 years after trauma. Male patients were mainly affected (7:1). In four the intraosseous epidermoid cysts were confused with other osteolytic diseases before surgery. Magnetic resonance imaging is recommended in any case of an osteolytic, expanding lesion, particularly in cases that are clinically and radiologically not obviously an intraosseous epidermoid cyst.

Objective: to study the structure of the disease and develop tactics of treatment of patients with single and rare epileptic seizures. Materials and methods. 1200 patients with epilepsy were examined, 103 patients were identified who had no more than 3 seizures throughout their life. Study included evaluation of anamnesis, clinical and neurological examination, routine electroencephalography and/or videoelectroencephalographic monitoring, magnetic resonance imaging of the brain. Results. Relapse of seizures in individuals with a history of follow-up occurred in 32 % of cases; epileptogenic changes in magnetic resonance image and, especially, anatomical and electro-clinical correlation of the epilepsy focus were associated with the risk of relapse. Conclusions. The decision on drug therapy after the first unprovoked seizure should be based on the ratio of the risk of repeated seizures and the risk of side effects. This solution should be individual and take into account not only medical problems, but also the preferences of the patient and his family members.

Anastomotic Urethroplasty

Background: Dhaka Medical College Hospital is the highest referral center for PFUI. As anstomotic urethroplasty is a challenging surgery and most of the surgeons refer these type of injuries to our center, we performed this study to evaluate the outcome of our cases. Objective: This study aims to find the outcome and complications of perineal end to end anastomotic urethroplasty in the management of posterior urethral injury resulting from pelvic fracture. Materials and Methods: We performed 147 perineal bulbo-prostatic anastomotic urethroplasty for PFUIs from January, 2013 to May, 2019. Mean age was 37 years with majority between 21 to 50 years (>85%). Nine patients had history of failed anastomotic urethroplasty. After surgical intervention patients were discharged with a supra-pubic catheter (SPC) and per urethral catheter in situ. On 22nd POD urethral catheter was removed and SPC on the next day if patient can void normally. 1st and 2nd follow up done on of 3rd and 6th month respectively following surgery. If patient voided well and Qmax>15ml/ sec; repair was defined as successful. Results: Success rate of anastomotic urethroplasty for PFUI was 93.87%. Total 9 procedures were failed including 2 urethro-cutaneous fistula and needed re-do anastomosis. Erectile dysfunction (ED) was present in 18 patients before operation and after surgery 12 more patients developed ED and total number was 30 during first follow up, which reduced to 24 during second follow-up. Two patient developed incontinence which improved in subsequent follow-up. Conclusion: Anastomotic urethroplasty remains the gold standard in the management of PFUI. Erectile dysfunction is the main issue to be concerned and need special attention. KYAMC Journal Vol. 10, No.-4, January 2020, Page 179-183

Abstract Background Chronic Chagas cardiomyopathy (CCC) is classically related to higher occurrence of thromboembolic events, especially stroke, particularly in patients with atrial fibrillation (AF). However, risk factors for stroke in patients with CCC but no atrial fibrillation have not been well established. Purpose We aimed to assess the relationship between left ventricular (LV) structure and function, as evaluated with cardiac magnetic resonance (CMR), with stroke in individuals with CCC. Methods We prospectively collected data from 141 patients with CCC who underwent CMR from October 2009 to December 2013 and who were thereafter followed for a median period of 6.8 years. The outcome was the occurrence of stroke during the follow-up period. The only exclusion criteria were history of previous stroke, AF or use of oral anticoagulant (OAC) at the time of CMR. CMR-derived LV parameters were: LV ejection fraction (LVEF), extension of LV myocardial fibrosis, assessed by late gadolinium enhancement, and presence of LV apical aneurysm. LVEF was classified as follows: (I) normal ≥55%; (II) mid-range <55% and ≥40%; and (III) reduced <40%. Age and gender were covariates in the adjusted Cox proportional hazard model. Results Of the initial 141 CCC participants, 25 subjects were excluded due to previous stroke (n=2), history of AF (n=11), or use of OAC (n=12). The remaining 116 individuals had a mean age of 56±14 years, 51% women. Normal, mid-range and reduced LVEF were found in 48 (41%), 43 (37%), and 25 (22%) patients, respectively. Myocardial fibrosis was detected in 79 of 111 (71%) subjects in whom the detection method was feasible. The extension of LV fibrosis was evaluated as a median of 4.6% [interquartile range: 0–10]. LV apical aneurysm was identified in 36 (31%) patients. During the follow-up (median 6.8 years), stroke was reported in 9 participants. In the univariate analysis, reduced LVEF was significantly associated with higher risk of stroke compared to normal LVEF (HR: 9.2, 95% CI: 1.8–48.4), while there was no significant difference between mid-range and normal LVEF (HR: 1.2, 95% CI: 0.2–8.2). The association of reduced LVEF and stroke remained significant in the multivariable model, adjusted for age and gender (HR: 12.6, 95% CI: 1.9–83.2). Kaplan-Meier curves are presented in figure 1 (logrank p-value <0.001). Neither the extension of LV myocardial fibrosis (HR: 1.0, 95% CI: 0.9–1.1) nor the presence of LV apical aneurysm (HR: 1.9, 95% CI: 0.5–7.2) was related to higher risk of stroke. Conclusion In patients with CCC, reduced LVEF assessed by CMR, but not LV fibrosis or presence of apical aneurysm, was a significant predictor of stroke.
