Infraorbital dark circles refer to the darkness of lower eyelids and can be a significant cosmetic problem for the people of any age and sex. Although the general concern for dark circles is increasing, little has been published about the treatment of dark circles in the scientific literature. Dark circles are not a single disease but combination of causative symptoms. We classified patients to five groups according to patients’ symptoms; bulging of infraorbital fat (Ia), sunken lower eyelids (Ib), depression or groove on midface (Ic), thin translucent skin (IIa), and excessive pigmentation (IIb). We reviewed medical records and photographs of patients retrospectively. The classification of patients and the treatment of the groups were evaluated. Problems of shape, especially bulging of infraorbital fat was the main cause of dark circles in most patients (65.2%). The treatment of each group included transconjunctival fat reposition or removal (Ia), single fat cell graft (Ib,IIa), microfat graft (Ic), and various dermatologic therapies (IIb). We obtained better results when we did combination of the treatments according to symptomatic groups. (Archives of Aesthetic Plastic Surgery 17: 91, 2011)

Transconjunctival lower blepharoplasty has gained interest because of less-invasiveness and fast recovery. This is a study about operative skill, strength, and weakness of transconjunctival lower blepharoplasty and a trial for suggesting the guidelines for patient selection. The authors reviewed the medical records and photographs of 530 patients (M:F=470:60) who underwent transconjunctival lower blepharoplasty with orbital fat reposition and subperiosteal septal reset, retrospectively. Most of the patients were satisfied with results for correction of orbital fat bulging and tear trough deformity. Eighteen patients (3.4%) developed relapse of fat bulging requiring revision with subsequent fat removal (seventeen patients) or fat reposition (one patient). Two patient (0.4%) developed entropion. One case was corrected with revisional surgery and the other case was recovered after an injection of triamcinolone. Delayed hematoma was developed in five patients. Surgical evacuation was required in 3 cases. Minor problems included postoperative swelling, bruise, and transient paresthesia that resolved spontaneously. Transconjunctival lower blepharoplasty is an excellent surgical choice for correction of orbital fat bulging and tear trough in the patients who have proper tension of soft tissue. Invisible scar, fast recovery, and low complication rate are merits of this method. (Archives of Aesthetic Plastic Surgery 17: 83, 2011)

Until now, aesthetic concerns have been focused on the face, especially on the eyes, nose and facial contour. But recently, many people have interest in the aesthetics of the trunk and extremities. There is an increasing demands for the correction or improvement of the trunk and extremity contour, especially in cases of poliomyelitis and posttraumatic deformity. Authors did the thigh augmentation with silicone prosthesis in a poliomyelitis patient. Subfascial pocket was made and prefabricated silicone implants were placed in the pocket.Circumferential differences between affected thigh and unaffected thigh were reduced from 11cm(15cm above knee), 9cm(25cm above knee) to 2.5cm, 3cm. No definitive complication was present. So, authors conclude that this technique is useful to obtain the good results in the aesthetic correction of asymmetric thigh.

Purpose: Microfat graft is a common procedure for correcting tear trough deformity and dark circle. Because the tissue on this area is very thin, the grafted fat, sometimes, induces palpable lumps and uneven skin contour. When it happens, the surgical removal of the grafted fat is often needed. The authors made attempt of transconjunctival approach for removal, and this made infraorbital fat repositioning possible at the same time. Methods: 15 female patients with history of microfat graft on lower eyelid, got operation for the grafted fat removal with transconjunctival approach from April of 2009 to July of 2010. The dissection was performed in accordance with infraorbital fat repositioning surgery. Through the transconjunctival incision, knotted fat on orbital septum and orbicularis oculi muscle was removed without damage on skin. After grafted fat removal, subperiosteal space was made 1 ~ 2 mm below the inferior orbital rim by elevating periosteum. With preserving orbital septum, infraorbital fat was repositioned and anchored to subperiosteal space. Finally, transconjunctival incision was closed with absorbable suture material. Results: 14 patients in the study showed satisfactory results. The problems like uneven skin contour and knotted fat mass, were all solved. In only one patient, incomplete correction was observed, as bulging on her right lower eyelid still remained. One patient complained of transient numbness on lower eyelid, but there was no specific complication other than this. Conclusion: The authors attempted the method of transconjunctival approach to remove former grafted fat in lower eyelid and reposition infraorbital fat simultaneously. Since the study brought great results, the method would be helpful to patients and surgeons.

Calcium has been implicated as a primary pathogenetic mediator of cellular injury under conditions of oxygen and substrate deprivation in the kidney such as ischemic acute renal failure(ARF). However, a role of Ca^(++)-ATPase, one of the important intracellular calcium regulating machineries participating in the calcium ion translocation is unclear in ischemic ARF. The author evaluated the change of Ca^(++)-ATPase and influence of verapamil, well known calcium channel blocker, on Ca^(++) -ATPase before and after renal ischemia. The experimental animals, cats divided into 3 groups. Group Ⅰ (n=6) was ischemic ARF model by renal artery clamp for 60 minutes, group Ⅱ (n=5) was ischemic ARF with a verapamil pretreatment (5 ㎍/kg/min), systemically, and group Ⅲ (n=7) was ischemic ARF with verapamil and piroxicam pretreatment. The results were as follows. 1) Creatinine clearance before and after clamp were 10.79±1.79 and 2.09±1.70ml/ min/kg in group I , 3.41±1.56 and 0.12±0.05ml/min/kg in group Ⅱ and 6.8±5.6 and 0.8±0.7ml/min/kg in group Ⅲ, respectively. 2) Creatinine clearance decreased significantly in group Ⅱ, 96±2% compard with group Ⅰ 61±30 %. A reduction rate of creatinine clearance in group Ⅲ , 84±11 % was not different significantly from other groups. 3) A Ca^(++) - ATPase of renal tubular cell before clamp was almost negative. Luminal and posterobasal surface of proximal tubule showed slightly increased Ca^(++) - ATPase activities after clamp but the difference of location and activity of Ca^(++) - ATPase among each group was not significant. These results suggested that Ca^(++) - ATPase were activated after ischemia to compensate ischemic insults which resulted in a increased intracellular calcium. There were no benefits to protect renal function from ischemia and seems no effects on the location and activity of Ca^(++)- ATPase by systemic pretreatment of verapamil for ischemic ARF.

Purpose: LASIK, one of the currently popular ophthalmic procedures, can sometimes result in dry eye symptoms. In the patient who had underwent LASIK operation, the periorbital surgery may be more likely to lead to such a complication as dry eye symptom. We would like to report a case of corneal abrasion occurred after transconjunctival blepharoplasty in post-LASIK state and suggest the method about preventing the complication. Methods: A 30-year-old female patient underwent transconjunctival blepharoplasty and microfat graft into the face. She had history of LASIK operation 2 years ago. Corneal protector was applied to both eye during transconjunctival operation. After the surgery, she complained of visual blurring at left side. Ophthalmic examination revealed corneal abrasion of left eye. Results: Cornea protecting lens was applied to left eye for 2 weeks. Steroid and antibiotic eye drops were applied for relieving the symptoms and the prevention from progressing of complication. After 1 week, visual power and acuity was recovered to preoperative state. No other specific complications happened. Conclusion: Post-LASIK patient may have possibility of decreased corneal sensation and tear production. Preoperative ophthalmic examination is recommended for the prevention of complication. When corneal protector is applied, we suggest Optagel^® as a useful lubricant.

N/A Calcium has been implicated as a primary pathogenetic mediator of cellular injury under conditions of oxygen and substrate deprivation in the kidney such as ischemic acute renal failure (ARF). However, the role of Ca++-ATPase in ischemic ARF, one of the important intracellular calcium regulation machineries participating in calcium ion translocation is unclear. The authors evaluated the changes of Ca+-ATPase before and after renal ischemia. The experimental animals, cats, were divided into 3 groups. Group I (n=6) was ischemic ARF model by renal artery clamp for 60 minutes, Group II (n=5) was ischemic ARF with a verapamil pretreatment (5 ㎍/kg/ min), systemically, and Group III (n = 7) was the same as Group II but with nonsteroidal antiinflammatory drug pretreatment. The results were as followings: 1) In Group I, creatinine clearance was 10.79±7.19 ml/min/kg before clamp and decreased to 2.09±1.70 ml/min/kg, and Group II, 3.41±1.56 to 0.12±0.05 ml/min/kg, and in Group III, 6.8±5.6 to 0.8±0.7ml/min/kg, respectively. 2) Creatinine clearance decreased significantly in Group II, 96±2% compared with Group I, 61±30%. A reduction of creatinine clearance in Group III was 84±11%, not different significantly from the other groups. 3) A Ca++-ATPase of renal tubular cell in the preischemic period was almost negative. The luminal and posterobasal surface of the proxima1 tubule showed slightly increased Ca++-ATPase activities in the postischemic period but the difference of location and activity of Ca++-ATPase among each group was not significant. These results suggested that Ca++-ATPase was activated after ischemia to compensate for ischemic insults resulting in increased intracellular calcium. There were no benefits to protecing renal function from ischemia and therefore no effects on the location and activity of Ca++-ATPase by systemic pretreatment of verapamil for ischemic ARF.
