Aplastic anaemia, Agranulocytosis & Epistaxis—when combines in one patient together becomes fatal. Here three case reports are given, all of them suffered from these three diseases simultaneously. All died in spite of best treatment except bone marrow transplantation. It was not done because of non-availability of HLA typing & marrow donor. 相似文献

The lingual vessels and its branches being superficial at under surface of tongue and floor if mouth may get injured during
surgery over of floor of mouth.In two cases, lingual vessels were severed accdentally during surgery with excessive haemorrhage.
This study was done to care the lingual vessels during surgery. Four main surgical dangerzone are found and emphasis is being
given to be over cautious while operating over this surgical danger zones.
Surgery over the floor of mouth is done in a number of conditions. Lingual vessels being very superficial, its sub-lingual
branches are damaged during surgery if surgeon is not cautious and may create problems.To avoid this, thorough knowledge of
correct surgical anatomy, course & relation of lingual vessels and floor of mouth is essential. 相似文献

The functional status of the descending motor pathways was assessed in malnourished children using transcranial electromagnetic stimulation of the cortex. Twenty children with different severities of malnutrition and 20 control subjects were studied electrophysiologically. The circular coil of a Dentac MAG 2 magnetic stimulator was applied tangentially over the vertex to stimulate the cortex. The muscle evoked potential in the children's arms was recorded from the abductor pollicis brevis muscle and in their legs from the extensor digitorum brevis muscle on both sides of the body using surface electrodes. The muscle evoked potential of the abductor pollicis brevis and extensor digitorum brevis muscles was further obtained using root stimulation by applying the coil at the cervical and lumbar spine, respectively. The indices of cortical threshold, cortical latency, and central motor conduction time (ms) were evaluated in both arm and leg muscles on both sides. The results showed an increased cortical threshold (mean (SD) 1232.5 (134.06) in the study group v 1147.5 (99.31) in the control group) for the abductor pollicis brevis muscle and for the extensor digitorum brevis muscle (1325.00 (115.70) in the study group v 1190.0 (125.24) in the control group). Similarly, significant prolongation of the central motor conduction time (ms) (study group 6.67 (0.91) v control group 5.71 (0.74)) in the abductor pollicis brevis muscle was seen in malnourished children. 相似文献

We present a rare case of COVID-19 associated conjunctivitis where patient presented with redness, foreign body sensation, watering, and pain. Symptoms started while patient was COVID-19 positive. On examination, severe conjunctival congestion was present along with follicles. Visual acuity was 6/6 in both eyes. The patient was started on topical antibiotics and showed improvement but again presented with aggravated symptoms. Conjunctival swab was sent for culture and sensitivity, which was negative for any organisms. The patient was then started on oral and topical steroid, which showed improvement. Even though COVID-19 associated conjunctivitis is self-limiting, here it showed a progressive course and resolved only after steroid. 相似文献

We present a case report of a 2‐year‐old boy who presented to a local hospital to evaluate vague abdominal symptoms of one‐month duration. The patient, therefore, had an open cystogastrostomy and drainage of the free abdominal fluid with minimal complications. He was monitored for several days after his surgery. 相似文献

BackgroundTraditionally, intracranial pressure is measured by direct ventriculostomy, which is invasive. Noninvasive measures such as bedside ultrasound and magnetic resonance imaging have been advocated and utilized recently to assess the intracranial pressure. The role of this study is to determine the degree of agreement between measurements of the optic nerve sheath diameter by computed tomography (CT) and magnetic resonance imaging (MRI).Materials and MethodsRetrospective chart review of 100 consecutive patients who had both MRI and CT scan of the head from January 1, 2011, until March 31, 2013, at our center was performed. A discrepancy of 0.2 mm between the 2 measurements was set as acceptable difference. The measurements of optic nerve sheath diameter (ONSD) were compared for agreement between the 2 modalities using the method by Bland and Altman.ResultsA total of 100 patients with both MRI and CT scan of the head were selected. Of these 100 patients, 24 were male and 76 were female. The average age was 63 years. No ONSD abnormality was detected in any of the patients. The discrepancy in measurements of the ONSD between CT and MRI in transverse plane was less than the predetermined cut-off value of 0.2 mm. Within-subject variance was estimated at 0.0058 for both CT and MRI.ConclusionComparable results without significant discrepancy as predetermined by the study groups were obtained from CT scan. Measurement of ONSD by CT scan can be used to indirectly asses the intracranial pressure in addition to clinical assessment and other signs of increased intracranial pressure on CT scan. 相似文献

Fractures of the proximal humerus are uncommon in young patients.Although bilateral fracture of proximal humerus itself is rare,association with epilepsy and electrocution is frequent.Only one case of traumatic bilateral proximal humerus fracture has been reported in the literature.We report a rare case of bilateral traumatic displaced proximal humerus fractures in a 40 years old male patient,which was treated by means of open reduction and internal fixation with proximal humerus locked pates on both sides and obtained a good functional outcome. 相似文献
