A surgical approach to the sublingual salivary gland.

A new surgical approach to the sublingual salivary gland is described, the key feature of which is the use of a flap rather than the usual incision. The flap includes the submandibular duct and, because of the relationship of the duct and lingual nerve, allows early identification of the latter before dissection of the gland. Improved access also simplifies dissection of the gland, particularly on its deep aspects where troublesome bleeding may be encountered.     

臂丛神经根性损伤膈神经移位术对青壮年患者早期呼吸功能的影响

目的研究臂丛神经损伤膈神经移位术对青壮年患者早期呼吸功能的影响.方法对16例接受膈神经移位治疗的患者,在术前、术后（10 d）进行肺功能指标的比较,同时定期进行门诊随访,观察呼吸系统自觉症状程度.结果13例术后出现了不同程度的供氧不足症状,16例全部出现一侧膈肌抬高,术后第10天肺活量（VC）、肺活量预计值百分数（VC%）分别比术前减少37.98%和26.88%,两者差异有统计学意义（tvc=11.532、tvc%=0,P＜0.01）.其它项目如残气量（RV）较术前轻度下降,肺总量（TLC）下降值达到术前肺总量的36.49%,残气量/肺总量比值（RV/TLC%）较术前上升了4.75%,上述各指标的差值均有统计学意义.1 s用力呼气量/用力肺活量比值（FEV1/FVC）和术前比基本无改变,但其差值有统计学意义.膈神经移位右侧（10例）与左侧（6例）术前、术后肺活量比较差异有统计学意义.术后随访8个月～2年,所有患者均无明显呼吸困难和胸闷等症状.结论膈神经移位术后对青壮年患者肺容量有较大的丧失,肺通气功能减弱和小气道阻力增加,但其丧失程度在机体自身代偿耐受范围内,不会导致急剧发生的严重呼吸功能障碍.建议对右侧臂丛神经根性损伤的患者,术前进行严格的肺、心功能检查,避免发生较为严重的并发症.     

Anatomic basis of the liver for the development of a perihepatic prosthesis

We studied specimens from 50 cadavers (27 men and 23 women) to obtain anatomical data concerning the liver and its attachments. The results allowed us to develop a polyglactin perihepatic prosthesis for compression of the injured liver. The falciform ligament and a narrowing of the hepatic parenchyma at this level allow attachment of the prosthesis. Separate prostheses were designed for each lobe. Clinical use has demonstrated that our prosthesis can be used to achieve effective control of haemorrhage and bile leakage.

Etude anatomique du foie. Développement d'une prothèse péri-hépatique

Résumé Sur une série de 50 pièces anatomiques d'adultes (27 hommes, 23 femmes), l'étude morphométrique du foie, de ses attaches dorsales et leurs variations a permis la confection d'une prothèse périhépatique en polyglactine adaptable à chaque lobe et fixée grâce à des artifices anatomiques. Celle-ci assure une compression efficace du parenchyme lésé et donc une hémostase et une bilistase correctes. Le ligament falciforme et le rétrecissement du parenchyme hépatique à son niveau assurent le maintien de la prothèse. Un exemplaire a été réalisé pour chaque lobe.

     

The relationships among social support and short- and long-term recovery outcomes in men with coronary heart disease

To determine the extent to which social support from the spouse and a health care provider (HCP) is associated with short- and long-term recovery outcomes in individuals after a cardiac illness, 93 patients were interviewed 2 months (short-term) after their event; 73 (78%) subjects responded to a follow-up questionnaire 1 year later (long-term). Tangible aid from the spouse was associated with better short-term psychological recovery. Satisfaction with and more emotional support from the spouse were associated with better short- and long-term psychological recovery outcomes. Greater satisfaction with HCP support was associated with patients' short- and long-term physical recoveries. These results highlight the value of different sources and types of support as having differential effects on physical and psychological recovery outcomes. ©1995 John Wiley & Sons, Inc.     

Decreased serum levels of nutritional biochemical indices in healthy children with marginally delayed physical growth

Biochemical markers of nutritional status (albumin, transthyretin, insulin-like growth factor-I and zinc) were measured in slowly growing two- to five-year-old, low-income Parisian children whose weight-for-height or height-for-age z scores (WHZ or HAZ) were between — 1 and — 2 SD of the NCHS median. The results were compared to controls who were matched for age, sex, and ethnic origin with WHZ and HAZ between — 1 and + 2 SD. Mean serum levels of transthyretin, albumin and insulin-like growth factor-I and mean plasma zinc concentrations were significantly lower in the growth-impaired children than in the controls ( p = 0.002, p = 0.006, p = 0.015, and p = 0.035, respectively). While the height-retarded children had low mean serum insulin-like growth factor-I values, the weight-retarded subjects had decreased levels of albumin, transthyretin and zinc when compared to controls. Lower mean levels of nutritional markers in healthy, slowly growing children suggest that inadequate dietary intakes of zinc, protein and/or energy may result in marginal delays in weight and height gains.
