Pigmented Paravenous Retinochoroidal Atrophy(PPRCA) is a type of pigmentary retinopathy that affects mostly both eyes symmetrically without inheritance. The PPRCA occurs in both progressive and non-progressive forms, but most cases are non-progressive forms. The fundus appearance of PPRCA is characteristic, with peripapillary pigmentary change as well as areas of retinochoroidal atrophy adjacent to the perivenular pigmentary change. The authors have studied a case of PPRCA which was diagnosed through the characteristic fundus appearance and other ophthalmological examinations.

A 32 year-old man was scheduled for tracheal reconstruction after having special radiological studies and pulmonary function tests. Atropine was given preoperatively. A radial artery cannula was inserted for blood gas sampling and direct arterial pressure monitoring. The E,K.G. was monitored continuously. With the patient breathing a high concentration of oxygen from a mask, halothane was added to the inspired gas. After intramuscular injection of ketamine, halothane was discontinued. Spontaneous respiration was preserved with assistance when necessary. The larynx, pharynx and trachea were topically anesthetized and then a large-bore rubben orotracheal tube was placed in the trachea above the lesion. Anesthesia was maintained with additional ketamine injection. The trachea was explored through an anterior transverse cervical incision with a median sternotomy. The segment distal to the obstruction as dissected and found to be maligant tissue extending down to near the carina and behind the aortic arch. So, it was imperative to postpone further the surgery. Immediately after skin closure, the trachea was almost completely obstructed and PaCO2 value was above 150 mmHg. Therefore the airway was preserved by a pediatric bronchoscope, which was replaced by a pediatric endotracheal tube. Anesthetic management and tracheal resection and reconstruetion have been reviewed problems of induction in a patient with tracheal obstruction are discussed, and the technics for retaining control of the airway and reducing the hazards of hypoxia and hypercarbia are also stressed.

Background: Cellulitis is an inflammatory disease of the skin and subcutaneous tissue caused by bacterial infection and is one of the most common reasons for admission to the Department of Dermatology. There are many biomarkers to help diagnose inflammatory diseases, and the neutrophil-to-lymphocyte ratio (NLR) has recently been raised as an option. Objective: This study aimed to evaluate the efficacy of pretreatment NLR for predicting the severity and prognosis of cellulitis. Methods: We reviewed the medical records of 102 patients diagnosed with cellulitis over the past 5 years. White blood cell count, erythrocyte sedimentation rate, C-reactive protein (CRP) level, procalcitonin level, and NLR were measured on the first day of admission. The associations of CRP, procalcitonin, and NLR ratio with body temperature and number of hospitalization days were assessed. Results: The CRP level and NLR were positively correlated with body temperature. In addition, positive correlations were found between the number of hospitalization days and biomarkers (p＜0.05), with the NLR showing the highest coefficients. Conclusion In patients with cellulitis, the NLR is a helpful parameter for evaluating the severity and prognosis of the disease. However, further studies are required to confirm this.

We report a case of bilateral hand complications following Artecoll injections that were successfully managed with surgical excision and reconstruction using MatriDerm and split-thickness skin grafts. Notably, the patient experienced no postoperative foreign body reactions and achieved excellent functional outcomes, with a complete range of motion at 3.5 years postoperatively. This case underscores the effectiveness of MatriDerm-assisted reconstruction in achieving both functional and aesthetic results.

BACKGROUND AND OBJECTIVES: Turner and colleagues introduced a new method that can detect tinnitus in animals. The stimulus is composed of a small background noise that is identical to the pitch of the tinnitus and a large pulse noise that can evoke a startle response. In normal rats, the gap decreases the startle reflex. However, in tinnitus rats, the gap does not decrease the startle reflex. The goal of this study was to optimize the stimulation paradigm so that the prepulse inhibition of N1-P2 amplitude would be maximized in the normal human subjects. SUBJECTS AND METHODS: Seven normal control subjects without tinnitus were recruited. The stimulus was composed of two different sounds: the softer background noise and the louder pulse noise. A 50 msec silent gap was inserted before the pulse noise as the gap condition (G condition) but not in the no-gap condition (N condition). The averaged amplitude of the N1-P2 cortical response was recorded for the G and N conditions. RESULTS: The G/N ratio was the smallest when the gap was 20 msec prior to the pulse noise. The G/N ratio was 84.8+/-16.8% with the Hanning window and 78.5+/-5.9% without the window. The G/N ratio was 91.1+/-24.9%, 78.0+/-5.4%, and 79.0+/-18.1% when the intensity of the background noise was 10, 20, and 32 dB SL, respectively. When the intensity of the background noise was 20 and 32 dB SL, the N1-P2 amplitude of the G condition was significantly smaller than that of the N condition. CONCLUSIONS: The optimal stimulus should be composed of the 1 kHz pulse noise without Hanning window. The intensity of the background noise should be 20 dB HL and the location of the gap should be 20 msec prior to the pulse noise. It seems that with these optimized parameters we could expect a 78.0% inhibition of N1-P2 amplitude in normal subjects without tinnitus.
