EARLY CARCINOMA TONGUE – SURGICAL OPTIONS

A retrospective analysis of 127 surgically treated cases of T-1, T-2 carcinoma of oral tongue during the period 1987-1990 was undertaken. 68.5 per cent (87) underwent hemiglossectomy and 31.5 per cent (40) underwent wide excision. There were loco-regional recurrences in 22 per cent (27). In the hemiglossectomy group 9 per cent (8 of 87) had local recurrences compared to 25 per cent (10 of 40) of wide excision group, (P = 0.01). Mean disease free survival was 40 months and 33 months for hemiglossectomy group and wide excision group respectively, (P = 0.006). It is seen that local recurrences are significantly less for the hemiglossectomy group compared to the wide excision group.KEY WORDS: Disease free survival, Early cancer, Recurrence, Surgery, Tongue     

放射抑制冠状动脉支架术后增殖试验亚型分析

大量的动物实验和许多早期临床试验显示放射在冠状动脉再狭窄治疗中的价值。为了建立有效的放射实施技术及合适的病例选择标准,作者进行了这项研究。ＳＣＲＩＰＰＳ试验是一项小样本的双盲法随机研究,病例入组标准是患者冠状动脉再狭窄已置支架或准备置支架;先前病灶处介入间隔>4周;参照血管直径在3～5ｍｍ之间,病灶长度≤30ｍｍ。将病例随机分成两组:一组后装管内用192Ｉｒ源,而另一组为假源。192Ｉｒ源的放置取决于病灶的长短。较短的病灶用一长19ｍｍ的带状物,该带状物含有5个长3ｍｍ的192Ｉｒ源,每个源间隔1ｍｍ,较长的病灶用含9个192Ｉ…     

Once-daily therapy for streptococcal pharyngitis with amoxicillin

OBJECTIVE: An orally administered antimicrobial regimen for the treatment of group A beta-hemolytic streptococcal (GABHS) pharyngitis given once rather than multiple times each day would be more convenient and might result in improved patient compliance. The purpose of this study was to evaluate the effectiveness of once-daily amoxicillin in the treatment of GABHS pharyngitis. PATIENTS: Children presenting to a private pediatric office with GABHS pharyngitis. DESIGN: Patients were randomly assigned to receive orally either amoxicillin (750 mg once daily) or penicillin V (250 mg three times a day) for 10 days. Compliance was monitored by urine antimicrobial activity. OUTCOMES: Outcomes were measured by impact on the clinical course, eradication of GABHS within 18 to 24 hours, and bacteriologic treatment failure rate as determined by follow-up throat cultures 4 to 6 and 14 to 21 days after completing therapy. GABHS isolates were serotyped to distinguish bacteriologic treatment failures (same serotype as initial throat culture) from new acquisitions (different serotypes). RESULTS: During the 16 months of this study, 152 children between 4 and 18 years of age (mean, 9.9 years) were enrolled; 79 children were randomly assigned to receive once-daily amoxicillin and 73 were assigned to receive penicillin V three times a day. The children in the two treatment groups were comparable with respect to age, duration of illness before initiation of therapy, compliance, and signs and symptoms at presentation. There was no significant difference in the clinical or bacteriologic responses of the patients in the two treatment groups at the 18- to 24-hour follow-up visit. Bacteriologic treatment failures occurred in 4 (5%) of the 79 patients in the amoxicillin group and in 8 (11%) of the 73 patients in the penicillin V group. CONCLUSIONS: These data demonstrate that once-daily amoxicillin therapy is as effective as penicillin V therapy given three times a day for the treatment of GABHS pharyngitis, and if confirmed by additional investigations, once-daily amoxicillin therapy could become an alternative regimen for the treatment of this disease.     

Retrospective Study on Efficacy of Intermaxillary Fixation Screws

Background

We evaluated the efficacy of intermaxillary fixation (IMF) screws in the treatment of mandibular fractures.

Methods

Two hundred patients with mandibular fractures, treated by IMF using these screws, were evaluated by pre and postoperative panoramic radiographs. Clinical testing was carried out for vitality and abnormal mobility of teeth adjacent to the site of screw insertions. Other factors such as possible iatrogenic dental injuries, loss, breakage or screw cover by oral mucosa and postoperative occlusion were also studied.

Result

The most important complication noticed was iatrogenic damage to dental roots.

Conclusion

Use of intraoral cortical bone screws for IMF is a valid alternative to arch bars in the treatment of mandibular fractures. Iatrogenic injury to dental roots is the commonest problem which can be minimized by an experienced surgeon.Key Words: Intermaxillary fixation, Bone screws, Mandibular fractures, Iatrogenic injury     

Progressive and regressive changes in the nucleus pulposus. Part I. The neonate

Magnetic resonance (MR) imaging, correlated with anatomic sections, was used to characterize the progressive and regressive changes in the nucleus pulposus in neonates. The spines of five fetuses and five full-term infants between 16 and 40 weeks old were studied. In anatomic sections, the nucleus pulposus was sharply demarcated from the anulus fibrosus, Sharpey fibers were conspicuous, and a plate of primitive notochord was evident in the equator of the disk. On long repetition time (TR)/long echo time (TE) or long TR/short TE MR images, Sharpey fibers (low signal intensity) and notochord (low signal intensity) could be differentiated from the high-signal-intensity nucleus pulposus and anulus fibrosus. The major differences between the fetal and infant spines were the amount of notochord in the disk and ossification in the vertebral body.     

INITIAL EXPERIENCE WITH SHOCK WAVE LITHOTRIPSY AT ARMY HOSPITAL (R & R) DELHI CANTT

Army Hospital (R & R) has acquired an Electrohydraulic Lithotripter (DIREX NOVA), the first of its kind in the Armed Forces for the treatment of stone diseases. The first 200 patients who underwent Extracorporeal Shock Wave Lithotripsy (ESWL) have been analysed in this study. This being a pilot study would serve as a beginning of an ongoing experience with this non-invasive procedure and its benefits for the stone population in the Armed Forces.KEY WORDS: ESWL, Lithotripsy     

TRANSFUSION REACTIONS: AFMC EXPERIENCE

Transfusions of blood and its components are useful and lifesaving. Adverse effects occur during or after transfusion, called hazards or complications of blood transfusion. Complications/hazards of various types which occurred in the patients following transfusion of blood/blood components in Armed Forces Hospitals of Pune-Kirkee complex were analysed with relevant investigations. Out of a total number of 13,039 transfusions of blood and blood components from 01 June 1995 to 31 July 1997, there were 104 (0.8%) adverse reactions. Non haemolytic febrile transfusion reaction was the commonest seen in 73 (70.2%) transfusions, followed by allergic reactions in 19 (18.3%) cases. Nonspecific reactions were seen in 11 (10.6%). One haemolytic transfusion reaction occurred due to wrong labelling of blood sample received from the ward for compatibility testing. There were no fatalities.KEY WORDS: Blood transfusion, Complication, Febrile reaction
