Alopecia totalis is a varient of alopecia areata which is a depilated, round or oval patch, which developed on scalp, eye lashes, eye brows, and beared areas. There is two sisters, elder is 7 year -3month-old, younger is 5-year 7-month-old. Hair loss began to developed on scalp (especially on forehead) 2 months and and 14 months prior to visit to our OPD. We consult the psychiatric department, and concluded that the etiology of our cases are suggested to have emotional disturbances which are ambivalent mother and fear of loss

The aim of this narrative review is to describe treatment options for the posterior regions of the mandible and the maxilla, comparing short implants vs. longer implants in an augmented bone. The dental literature was screened for treatment options enabling the placement of dental implants in posterior sites with a reduced vertical bone height in the maxilla and the mandible. Short dental implants have been increasingly used recently, providing a number of advantages including reduced patient morbidity, shorter treatment time, and lower costs. In the posterior maxilla, sinus elevation procedures were for long considered to be the gold standard using various bone substitute materials and rendering high implant survival rates. More recently, implants were even placed without any further use of bone substitute materials, but the long-term outcomes have yet to be documented. Vertical bone augmentation procedures in the mandible require a relatively high level of surgical skill and allow the placement of standard-length dental implants by the use of autogenous bone blocks. Both treatment options, short dental implants, and standard-length implants in combination with vertical bone augmentation procedures, appear to result in predictable outcomes in terms of implant survival rates. According to recent clinical studies comparing the therapeutic options of short implants vs. long implants in augmented bone, the use of short dental implants leads to a number of advantages for the patients and the clinician.

The continuous perineural, perivascular compartment surrounding the brachial plexus from the tip of the cervical transverse process to the axilla may be entered at virtually any level, and the extent of anesthesia depends upon the level of entry and volume of local anesthetics injected. Various approaches of brachial plexus block were introduced to produce a successful block with the least complications. In this study, 25 ml of 0.5% bupivacaine hydrochloride solution was injected by subclavian perivasular approach to illustrate the effect of various locations of paresthesia on the distribution of analgesia in 50 patients who had an operation of the hand or forearm. The location of paresthesia evoked by insertion of a 23-gauge scalp needle during performance of brachial plexus block was checked at the distribution of the superior, middle, and inferior trunks. A pin prick test was performed at 15 min, 30 min and 45 min after injection of bupivacaine hydrochloride to evaluate the distribution of analgesia in the superior, middle and inferior trunk of the brachial plexus. The incidence of analgesia in all three trunks was the highest when paresthesia of the middle trunk distribution was elicited. The incidence of analgesia in the superior trunk distribution was significantly lower when inferior trunk paresthesia was elicited than when superior trunk paresthesia was elicited. Superior trunk paresthesia was the most frequently elicited. Complications were arterial puncture (32%), Horner's syndrome (8%) and hematoma (2%). The results indicates that brachial plexus block by supraclavicular subclavian perivascular approach is a relatively safe technique. Injection of local anesthetics following the confirmation of middle trunk paresthesia is desirable to obtain the successful block. Especially when analgesia of superior trunk distribution is required, the direction of needle insertion should be adjusted to avoid the inferior trunk paresthesia elicited.

Hemorrhagic radiation proctitis is infrequently seen in patients receiving pelvic irradiation. The treatment of hemorrhagic ralation proctitis is often difficult. Many patients need reyeated hospitalizations and blood transfusions. Occasionally patiets will develop severe or recurrent rectal bleeding. In case of massive bleeding requiring excessive transfusion, colonic diversion by construction of a colostomy or excision of the diseased segment may be inevitable. However, surgical procedures in these patients are associated with a high mortality and morbidity. Moreover, medical therapy is usually ineffective. Recently formalin therapy has been introduced as a simple and effective treatment for hemorrhagic radiation proctitis. We experienced a 69 year-old woman patient who developed severe homorrhagic proctitis 1 year after radiotherapy for carcinoma of the cervix. She had not improved by conservative management and required blood tranafusions and repetitive hospitalizations. After local application of a 4% formalin solution in the diseased rectum under caudal anesthesia, the bleeding immediately stopped and the patient was discharged from the hospital, and no recurrence has been observed until now.

This paper describes a case of intrapericardial teratoma in a 20-day-old female meonate, who suffered from cyanosis and respiratory difficulty. She was evaluated by echocardiography, chest CT and MRI, the suspected cyanosis and respiratory difficulty. She was evaluated by echocardiography, chest CT and MRI, the suspected intrapericardial mass was identified and surgically removed. The postopervative diagnosis was intrapericardial teratoma, grade II. This case is reported with brief review of some related literature.

BACKGROUND: Reactive oxygen species (ROS) are free radicals that induce lipid peroxidation and cause tissue damage. ROS are frequently produced by ischemia and subsequent reperfusion in clinical situation and like coronary artery bypass graft surgery and transplantation. More over, some anesthetics are known to act as an antioxidants and free radical scavenger and, the aim of this study was to explore the scavenging effects of thiopental and ketamine against ROS induced by isolated rabbit thoracic aortic endothelial damage. METHODS: Twenty white male rabbits (weighing 2.0-2.5 kg) were used. Thoracic aorta and were dissected free, cut into rings (3-4 mm), and suspended in an organ bath filled with 10 ml Krebs solution bubbled with 5% CO2 and 95% O2 at 37oC. The rings were equilibrated for 90 min and the solution changed every 15 min, and then a resting tension of 1.5 g was applied to the rings. Isometric tensions were recorded using a transducer connected to a data acqusition system (Biopac Inc. USA). Aortic rings were precontracted with norepinephrine (NE, 10-6 M), and changes in tension were measured after the cumulative administration of acetylcholine (ACh 3 x 10-7, 10-6 and 3 x 10-6 M) and nitroglycerin (NTG 10-5 M). Data are expressed as percentages of the 10-5 M NTG-induced relaxation (ACh/NTG). Percentages of ACh/NTG, before and after ROS exposure by electrolysis were noted for control and experimental groups. Aortic rings were pretreated with thiopental (3 x 10-5, 10-4 and 3 x 10-4 M, n = 9, 13, 17), ketamine (10-4 M, n = 8), catalase (1000 U/ml, n = 12), mannitol (3 x 10-4 M, n = 5) or not pretreated (free, n = 6). After 30 minutes, with the rings were exposed to ROS by electrolysis (DC 9 V, 20 mA, aortic rings 1 cm removed from the anode) in Krebs solution for 2 minutes. After electrolysis, the organ bath fluid was replaced with fresh Krebs solution, and the aortic rings were precontracted with NE and was vasorelaxation with ACh and NTG as above mentioned concentrations. RESULTS: Endothelium-dependent vasorelaxation was induced in all concentrations of thiopental groups in a dose-dependent fashion (P <0.05 vs control value) even with ROS attack. The catalase group produced vasorelaxation after ROS attack (P <0.05 vs control value). On the other hand, no ACh-induced significant endothelium-dependent vasorelaxation after ROS exposure was observed in the ketamine and mannitol pretreated group, or in the free group (P <0.05 vs control group). CONCLUSIONS: These findings suggest that thiopental and catalase preserve ACh induced endothelium-dependent vasorelaxation and that thiopental has a dose-dependent ROS scavenging effect like catalase.
