ABSTRACT
The eastern sub-Himalayan plain of India is a popular potato growing belt in which vast scope exists to introduce processing grade cultivars. The selection and introduction of a better quality processing grade cultivar in this region may pave the way for the processing industries. Keeping these in the backdrop, this study was conducted at Instructional Farm of Uttar Banga Krishi Viswavidyalaya (UBKV), Pundibari, Cooch Behar, West Bengal, India under eastern sub-Himalayan plains during winter seasons of 2016-17 and 2017-18 in which seven processing type potato cultivars (Kufri Chipsona-1, Kufri Chipsona-3, Kufri Chipsona-4, Kufri Frysona, Kufri Himsona, Kufri Surya and Kufri Chandramukhi) were evaluated in terms of different quality parameters pre-requisite for chips processing viz., dry matter content, specific gravity, starch content, chips colour score, crispiness and hardness of chips through randomised complete block design (RCBD). The study revealed wide variation in all quality parameters amongst the cultivars. Cultivar 'Kufri Frysona' showed the highest specific gravity (1.121) as well as dry matter content (23.35%) followed by 'Kufri Chipsona-3'. The cultivar 'Kufri Frysona' showed the highest starch content (28.52%) too. Chips prepared from 'Kufri Chipsona-1' were recorded to be crispier with a relatively lower value of deformation before the first break and less hardness value. All processing type potato cultivar reflected the chips colour score <3 (evaluated, based on 1-10 scale, 10 being the darkest and least desirable) though 'Kufri Frysona' had the lowest chips colour score (1.50) signifying its superiority for the region. 'Kufri Frysona' cultivation could be recommended in this agro-climatic region particularly for chips manufacturing potato industries.
ABSTRACT
Maxillofacial trauma, a common injury in urban population following road traffic accident or act of interpersonal violence of which orbital floor fractures is common. It impairs the integrity of the extraocular muscles and may be accompanied by enophthalmos, orbital deformity and diplopia. Orbital reconstruction is essential to improve anatomical and visual deformity. Repair of orbital floor is done by autologous bone graft or synthetic implants. Compare outcome of orbital floor reconstruction in blow out orbital fracture using autogenous bone graft from iliac crest, outer table of mandible, alloplastic implant- silastic block and titanium mesh. 30 patients having orbital fractures were considered in study population. All the patients were treated by ORIF and repair of floor by subcilliary incision. Out of 30 patients, repair of orbital floor was done by autologous bone graft from iliac crest in 7 patients (Group A), bone graft from outer table of mandible in 5 patients (Group B), implant using silastic block in 8 patients (Group C) and titanium mesh in 10 patients (Group D). Factors analyzed were age, sex, cause of fracture and treatment outcome in terms of correction of pre operative diplopia and enophthalmos, rate of development of post operative infection, wound dehiscence and implant exposure. All patents were reviewed at 4 weeks and 12 weeks following operation. 71.42% of patients in Group A had early correction of diplopia and enophthalmos. This was 100% in rest of the groups. All patients had complete correction when assessed at 12 weeks post operatively. Post operative complication rate was 20% and 12.5% in Group B and C respectively. There were no complications in the rest of the groups within the follow up period. No statistically significant difference as to the chance of occurrence of complication could be found amongst the groups. Autologous bone graft has no immunological reaction but donor site morbidity. Silastic block may case immunological reaction, infection, poor drainage of orbital floor. But titanium mesh for orbital floor repair has excellent outcome and superior to other modality of treatment.
ABSTRACT
Larynx is the second most common site for cancer in the upper aerodigestive tract. One of the dreaded complications following total laryngectomy has been pharyngo cutaneous fistula (PCF). PCF merits special attention due to its significant negative impact on the recovery process. Total laryngectomy profoundly alters speech. Effective voice restoration is essential for the rehabilitation of these patients. Inadequate consensus exists as to the best technique of pharyngeal repair to decrease incidence of PCF and ensure good quality voice following total laryngectomy. 21 patients were included in the study for total laryngectomy with trachea oesophageal voice prosthesis placement. Patients were randomised into 2 groups. Group A had their pharynx repaired in two layers and Group B had it done in three layers. Post operatively the patients were followed up for a period of 12 months to look for incidence of PCF. Subjective and objective evaluation of voice was done. 9.52% of patients developed PCF. All of the cases of PCF were in the group repaired in three layers. In cases with repair by two layers the mean Voice Handicap Index 10 (VHI 10) score was 19.27 and those with three layers pharyngeal repair was 23.20. Average maximum phonation time amongst the study population was 13.09. In three layers and two layers pharyngeal repair the average maximum phonation time was 12.56 and 13.58 respectively. Surgical repair of pharynx in two layers excluding the third layer of pharyngeal musculature reduces the chance of PCF. Two layers pharyngeal repair supplemented by cricopharyngeal myotomy led to significantly better voice outcome.
ABSTRACT
Twenty patients in the age group of 45-55 years with carcinoma of larynx underwent tracheostomy for acute upper airway obstruction. Tracheostomy tubes (no. 36) commonly available in the market have varying angle of curvatures ranging from 120° to 130°. In respect of different curvatures of the tracheostomy tubes, the various complaints of the patients were noted. The mean ideal angle of curvature of the tracheostomy tube should be 112° that was calculated from CT scan of neck with tube in situ.
ABSTRACT
AIM: (1) To evaluate the role of vestibular exercises in the management of benign paroxysmal positional vertigo (BPPV). (2) To compare the three vestibular exercises (Semont's manoeuvre, Epley's manoeuvre or Brandt-Daroff exercises) in the treatment of BPPV. SETTINGS AND DESIGN: Prospective randomised study METHODS AND MATERIAL: Fourty-eight patients diagnosed as BPPV in the study period November 2005-2006 were included in the study. They were randomly assigned to one of three groups, and the corresponding manoeuvre was done on them. Follow-up were at 2 weeks and 3 months. RESULTS: Thirty-five of the 48 patients (72.91%) reported relief of symptoms at 2 weeks and no recurrence of symptoms at 3 months. Result was best for the group which was subjected to the Epley manoeuvre (87.5%). CONCLUSIONS: Performance of any of the three manoeuvres can be expected to give good results in the management of BPPV. The Epley manoeuvre appears to be better than the other two in terms of relief of symptoms and prevention of recurrence.
ABSTRACT
study included 40 patients treated for CSOM with central perforation. Only type I tympanoplasty was done in 30 patients with dry central perforation and simple mastoidectomy with type I tympanoplasty was performed in 10 patients with moist or discharging perforation. Type I tympanoplasty utilizing an underlay technique with TFG shows high probability of success (85%). Presence of bilateral perforations lowers the success rate (66.66%). Status of non-operated ear is a significant factor for success rate. An overall hearing gain of about 10db was achieved. Poor pre-operative hearing status of elderly adversely influences post-operative improvement of hearing. Typel tympanoplasty with simple mastoidectomy results excellent surgical success rate (100%) but gives less improvement of hearing (closure of A-B gap= 3.3db). In type I tympanoplasty alone surgical success rate drops to 80-75% but is offers more improvement of hearing (closure of A-B gap = 6.708 db).
ABSTRACT
Rhinoplasty in atrophic rhinitis is a difficult surgery because the dorsal skin is adherent to the underlying structures. There is also more chance of postoperative injection. Our experience of various types of rhinoplasly in 25 atrophic rhinitis patients are presented here. The patients were from the age group 16 to 35 years. Most of the operations were done under local anaesthesia. Commonest graft used was conchal cartilage. Bone graft was avoided for augmentation because of its high rate of absorption in atrophic rhinitis. In 10 patients Young's operation was done in one side along with rhinoplasty. Young's operation was done only with skin layer.
