Haemorrhagic fever with renal syndrome: Clinical aspects

Based on clinical and pathological features a typical case of haemorrhagic fever with renal syndrome passes through five phases: (1) febrile phase, (2) hypotensive phase, (3) oliguric phase, (4) diuretic phase and (5) convalescent phase. The major manifestations are fever, pain in the back and abdomen, flushed face, prostration, proteinuria, purpura and haemorrhage and acute renal failure. Selective right auricular haemorrhage, marked congestion and haemorrhage in the renal medulla and necrosis of the anterior lobe of the pituitary gland are the three prominent pathological findings. The clinical severity depends upon the causative agents, namely Hantaan virus, Seoul virus and the European form in that order. Specific serological diagnosis of haemorrhagic fever with renal syndrome is made by demonstrating a rise in titre of specific immunofluorescent antibody against Hantaan and related viruses. The management is supportive, based on an understanding of the pathophysiology of the disease.

Preexpanded distant "super-thin" intercostal perforator flaps for facial reconstruction without the need for microsurgery.

BACKGROUND: Concept of the 'super-thin perforator flap' was introduced in 1994 by authors. Since then, various types of 'super-thin perforator flaps' were applied successfully especially for contour sensitive reconstruction such as face and neck. METHODS: Eleven patients requiring large flaps who presented with extensive disfiguring facial scar (male: seven cases, female: four cases). On the consideration of flaps' colour, texture and thickness requirements, the authors selected 'super-thin' anterior intercostal perforator flaps (AICP, range from 4 x 14 cm to 25 cm x 9 cm) for reconstruction purpose. First, tissue expanders (volume range from 800 cc to 1200 cc) were carefully inserted under the AICP. After the flaps were expanded for 2 months, distant scars were removed and the covering super-thinned flaps were transferred into recipient site. Two weeks later, pedicles in the anterior chest were cut down and flaps were transferred to replace all the left scars. RESULTS: Flap were survived without any complications. The colour, texture and thickness of the transferred flap were satisfactory, shrink of flaps were not observed after long term follow-up. The authors present a method of facial reconstruction that has the advantages of creating a large amount of thin tissue of both good colour and texture, without the need of microsurgery and few disadvantages of donor-site morbidity. The disadvantages are three-staged procedures, complications of tissue expansion and uncomfortable compulsory posture for patients. In our opinion, this is an alternative method of choice for reconstructing all large defects in the lower two-thirds of the face.     

颈椎椎体次全切除钛网钉板系统的临床应用

目的探讨颈椎前路椎体次全切除钛网钉板植骨融合的临床效果。方法自2001年3月～2003年3月间应用颈前路椎体次全切除钛网植骨融合及钉板固定治疗颈椎管狭窄性疾病22例，其中4例患者行2椎体次全切除3节椎间隙减压手术。术后观察减压、固定、融合及神经功能恢复情况，并行X线摄片或CT扫描检查。结果患者获6～12个月随访，神经功能得到不同程度改善，无加重情况。椎间隙高度无丢失、无成角，均获得骨性融合。术后3d在颈围领固定下下床活动，4周后可恢复较轻工作。结论此术式可避免传统手术方法的缺点，即不取自体髂骨，融合率高，稳定性好，并减压彻底，疗效好，是一种值得推广的新技术。

A new view of anterior choroidal artery territory infarction

Summary Infarction in the territory of the anterior choroidal artery (AchA) has been the subject of several recent reports. To the classical clinical syndrome of hemimotor, hemisensory, and visual field deficit has been added hemiataxia acute pseudobulbar mutism, pure motor and pure sensory syndromes and disorders of higher cortical function. The definition of anatomic and clinical correlates to AchA stroke is aided by CT-MRI findings and reveals an unexpected superior extension of infarct to include the periventricular caudate nucleus and inferior corona radiata. Prognosis depends upon unilaterality, bilateral strokes having often a fatal outcome. Etiology and treatment may be intimately related to hypertension.     

Ultrasonography in the detection of cervical incompetency

In 80 pregnancies with clinical and ultrasonic signs of cervical incompetency, the length of the cervix and the thickness of the anterior wall of a lower uterine segment have been evaluated ultrasonically. We have also measured the width of the endocervical canal and studied the prolapse of fetal membranes (with fetal parts) into the endocervical canal. We evaluated these same parameters in 80 healthy pregnancies. The length of the cervix, the thickness of the anterior wall of a lower uterine segment, and the width of the endocervical canal were followed longitudinally in the patients from the 10th to the 36th gestation week. No statistically significant differences between age groups were found. In four age groups at risk for cervical incompetency, cervical lengths and wall thickness were significantly different (p less than 0.001) from those in comparable controls. Forty-five percent of the patients in the at-risk group, with cervical cerclage, delivered at 37.3 (range: 32 to 41) weeks and 6.25% of pregnancies ended in abortion when the amniotic membrane herniated into the cervical canal, with or without some part of the fetus.
