Emphysematous cholecystitis is an uncommon condition which may mimic acute cholecystitis. But it differs from acute cholecystitis in its relatively greater frequency in men and diabetics and has graver prognosis. The condition is diagnosed by demonstration of air in lumen,wall of gallbladder and/or pericholecystic space using a variety of radiographic techniques: simple abdominal radiography, ultrasonography and CT scanning. One illustrative case is presented herein and the pertinent literature is reviewed.

On this study, silicone intubation was performed for punctal stenois in 10 patients(group 1), incomplete nasolacrimal duct obstruction in 47 patients (group 2), and complete nasolacrimal duct obstruction in 18 patients(group 3) in adults. Silicone tube was removed between 3-6 months(mean 5.7 months) after intubation. Mean follow-up period of 9.5 months, 9 patients(90%)in group 1,39 patients(83%)in group 2,and 8 patients(44%) in group 3 showed no epiphora, and 1 patient(10%)in group 1, 8 patients (17%) in group 2, and 4 patients(22%) in group 3 showed intermittent epiphora. 6 patients(33%) in group 3 showed persistent epiphora. In summary, silicone intubation can be an alternative to dacryocystorhinostomy in selected adult patients who have punctal stenosis and incomplete obstruction of nasolacrimal duct system. It is safe, and less traumatic with high success rate in these patients.

We compared the pain produced during different phases of phacoemulsification cataract surgery using a scleral pocket incision under pinpoint anesthesia with that under intracameral anesthesia. This prospective study comprised each 100 cataract patients who had no complications influencing the degree of pain during surgery. Patients were asked about pain immediately after each phase and pain occurring during each phase was measured using 4 step verbal scale(from 0 to 4). In both anesthesia,conjunctival reposition was the most painful.Pinpoint injection was statistically significantly more painful than induction of intracameral anesthesia.The pain score during conjunctival reposition and at 1hr after surgery were significantly higher under intracameral anesthesia than under pinpoint, but during most of phases under both anesthesia,the pain score was relatively low. Intracameral anesthesia is easy,safety and dose not require additional ocular damage during induction of anesthesia,so if combined with topical anesthesia,it is very effective during cataract surgery using scleral pocket incision.

The trachea is a cartilagenous and membranous tubular midline structure with parallel walls. Tracheal deviation may be caused either by traction toward the diseased hemithorax or by compression toward the normal side. Unless an obvious mass is observed radiographically, occasionally it can be difficult to decide whether the trachea has been pushed or pulled from its normal position in the mediastinum. We studied the differences between tracheal deviation patterns in 23 patients with fibroatelectatic pulmonary tuberculosis and 35 patients with elongated and dilated aortas. In cases of retraction of the trachea by fibroatelectatic pulmonary tuberculosis, the diameter of the deviated segment was greater than that of the normal segment and deviation of the wall adjacent to the fibroatelectasis from its normal position was greater than that of the opposite wall. In cases of compression of the trachea by the elongated and dilated aorta, the diameter of the diviated segment was smaller than that of the normal segment and deviation of the wall adjacent to the aortic arch from its normal position was greater than that of the opposite wall. We conclude that these differences between tracheal deviation patterns are useful signs for discriminating retraction from compression. Thus when the trachea is retracted, the deviation of the juxtalesional wall is greater than that of the lesion-free wall, and vice versa.

Visualization of falx cerebri on non-enhanced CT of children with severe head injuries (the falx sign) has been regarded as an evidence of subarachnoid hemorrhage. On the contrary, other authors have reported reverse results. To evaluate clinical significance of the falx sign, authors studied frequency of visualization and CT number of falx cerebri and dural sinuses in 65 children with head injury and 65 children without head injury examined by cranial CT at the Dep. of Radiology, St. Paul's Hospital, Catholic Medical College from March to Sept. 1981. All patients with head trauma were studied within 1 week of the traumatic event. Visualization of falx cerebri was observed at slice in the region of lateral ventricle and slice near to vertex respectively. On the slice in the region of lateral ventricle, falx cerebri was identified in 82% of all of the children examined, of which 92%showed partial visualization of falx cerebri and remaining 8% totally. On the slice near to vertex, falx cerebri was identified in 92% of all the children examined, of which 38% showed partial visualization of falx cerebri and remaining 62% totally. In head trauma group, frequency of visualization of falx cerebri was 78% on the slice in the region of lateral ventricle and 89% on the slice near to vertex; in non-traumatic group, frequency of visualization of falx cerebri was 86% and 94% respectively. The highest numerical value of the falx densities averaged 47 Hounflieds (range, 32-63) in non-traumataic group, averaged 49 Housfields (range, 32-69) in head trauma group. All or a portion of the superior sagittal sinus was visualized in 59% of all of the cases studied, 50% in head trauma group, and 69% in nontraumatic group. The straight sinus was identified in 45% of all of the cases studied, 39% in head trauma group, and 51% in non-traumatic group. In conclusion, there was no distinction between head trauma and non-traumatic group in visualization of falx cerebri and dural sinuses, and we could frequently identify the falx density in normal. Also we could find that frequency for visualization of falx cerebri and drual sinuses increased as the age increased.
