SUMMARYThe Cornell-Penn-Miner (CPM) Dairy is an applied mathematical nutrition model that computes dairy cattle requirements and the supply of energy and nutrients based on characteristics of the animal, the environment and the physicochemical composition of the feeds under diverse production scenarios. The CPM Dairy was designed as a steady-state model to use rates of degradation of feed carbohydrate and protein and the rate of passage to estimate the extent of ruminal fermentation, microbial growth, and intestinal digestibility of carbohydrate and protein fractions in computing energy and protein post-rumen absorption, and the supply of metabolizable energy and protein to the animal. The CPM Dairy version 3.0 (CPM Dairy 3.0) includes an expanded carbohydrate fractionation scheme to facilitate the characterization of individual feeds and a sub-model to predict ruminal metabolism and intestinal absorption of long chain fatty acids. The CPM Dairy includes a non-linear optimization algorithm that allows for least-cost formulation of diets while meeting animal performance, feed availability and environmental restrictions of modern dairy cattle production. When the CPM Dairy 3.0 was evaluated with data of 228 individual lactating dairy cows containing appropriate information including observed dry matter intake, the linear regression between observed and model-predicted milk production values indicated the model was able to account for 79·8% of the variation. The concordance correlation coefficient (CCC) was high (rc=0·89) without a significant mean bias (0·52 kg/d;P=0·12). The accuracy estimated by the CCC was 0·997. The root of mean square error of prediction (MSEP) was 5·14 kg/d (0·16 of the observed mean) and 87·3% of the MSEP was due to random errors, suggesting little systematic bias in predicting milk production of high-producing dairy cattle. Based upon these evaluations, it was concluded the CPM Dairy 3.0 model adequately predicts milk production at the farm level when appropriate animal characterization, feed composition and feed intake are provided; however, further improvements are needed to account for individual animal variation.
Craniometaphyseal dysplasia
Authors: Martin F. W. 
Published: November 2007

AbstractA case report of craniometaphyseal dysplasia is presented with a classification of this disease, supported by a review of the literature. Certain unusual features are observed—mastoid surgery and later contralateral temporary facial paresis. The patient showed no further deterioration of symptoms when last reviewed.Craniometaphyseal dysplasia is one of a number of craniotubular bony dysplasias. These dysplasias are characterized by (a) genetic transmission and (b) dysplastic or hyperostotic involvement of the cranial and tubular bones (Gorlin, et al., 1969). Craniometaphyseal dysplasia may be dominant or recessive in form, the latter being more severe in its clinical manifestations, viz. nasal obstruction and deformity and cranial nerve palsies, such as optic atrophy and loss of hearing. There may also be enlargement of the mandible and flaring of the metaphyses of long bones on X-ray examination.
Case report
Authors: Cook Peter L. , May Brendan R. 
Published: November 2007

AbstractAbstract A CASE is presented in which a post-cricoid web was shown arising posteriorly instead of in the almost invariable anterior situation. The patient was not anaemic and some brief comments are made on the inconstant relationship between anaemia and the presence of a web.Kelly (1919) related dysphagia to anaemia and described how ‘the gullet seemed closed by a web passing backwards from the cricoid’. Subsequent authors emphasize this and Waldenstrom and Kjellberg (1939) state that radiologically and at oesophagosopy there is ‘a thin semilunar membrane on the anterior wall stretching towards the lateral walls of the gullet’ Shamma'a and Benedict (1958) and Seaman (1967) state that webs arise anteriorly but may be circumferential.This report presents a patient with longstanding dysphagia and anaemia in whom a posterior pharyngeal web was shown.
Aural myiasis
Authors: Sharan R. , Isser D. K. 
Published: November 2007

AbstractA series of 14 cases of aural myiasis is reported. In no case unassociated with otitis media was perforation in the tympanic membrane seen. Local treatment with turpentine oil or ether was prescribed.Myiasis may be defined as infection of vertebrates with the larvae (maggots) ofDiptera flieswhich feed on the tissues of the host. It has also been called ‘Peenash’ or ‘Scholichiasis’. It is usually seen in the tropics. Myiasis is a far greater problem in sheep, cattle and deer than in man and there is no form of myiasis found exclusively in man. It may involve the nose, ears, eyes, mouth, tonsils, teeth, tracheostomy wounds, skin, vagina, urinary bladder and intestinal tract.Myiasis is produced by flies belonging to the Calliphoridae, Sarcophagidae, Gastrophilidae, Cuteribridae and species of Musca, Famina, Chrysomyia, C. vicinia, C. americana and the Tumbu fly. As reported by Sood et al. (1976) the commonest genera are Sarcophagidae. Rao (1929) reported that the causative flies for myiasis in India belong to the Muscae and Sarcophagadae.Myiasis of the ear is very rarely seen. The earliest report so far available in the literature is that by Brauneck in 1949, followed by others from Sahay (1959), Mishra and Mehta (1960), Bhatia and Dayal (1975), and Sood et al. (1976).In the present series 14 cases of aural myiasis out of 48 cases of myiasis seen during the period from 1965 to 1977 are presented. Of the remaining 34 cases 29 were of nasal myiasis and 5 of nasopalatine myiasis.
Metastatic melanoma involving the left maxillary antrum
Authors: Meyer Jack E. , Rogers William P. , Leiter Bruce 
Published: November 2007

AbstractMalignant melanoma may metastasize to any anatomic site via the hematogenous route. A patient is described in whom a metastasis developed in the left maxillary antrum and nasal cavity and who received successful palliative surgical and radiotherapeutic treatment.Metastatic carcinoma involving the paranasal sinuses has been reported most frequently secondary to renal cell tumors, followed by carcinoma of the lung and breast (Jortay, 1971; Robinson, 1973; Friedmann and Osborn, 1965; Bernstein et al., 1966). These tumor deposits are often diagnosed in a setting of diffuse metastatic disease or discovered at post-mortem examination. A patient recently treated at Pondville Hospital had symptomatic metastatic melanoma involving the left maxillary antrum and nasal cavity. Following surgical treat-ment, palliative radiotherapy was successfully delivered on three occasions providing symptomatic relief over the subsequent 17 months prior to the patient's death.
Hearing loss in perforations of the tympanic membrane
Authors: Ahmad S. W. , Ramani G. V. 
Published: November 2007

Abstract70 Patients with dry central perforations have been studied to assess the hearing loss. The hearing loss is greater at the lower frequencies and increases with the size of the perforation. Malleolar perforations cause more hearing loss than the non-malleolar unless the perforation involves less than 10 per cent of the tympanic membrance surface area. Perforations of the postero-inferior quadrant cause more hearing loss than those in the antero-inferior quadrant.The large effective surgace area of an intact and normally vibrating tympanic membrane plays a major role in the middle ear transformer mechanism. The loss of this surface area by perforation is bound to cause deafness (Mawson, 1962). The degree of hearing loss has been extensively studied in human cadavers (Békésy, 1939) and in cats (Bordley and Hardy, 1937; Payne and Githler, 1951) but not much published work is available on any detailed clinical study in human beings. Most authors have generally stated that ‘small perforations’ have little effect on hearing, and only low tones are affected (Wever and Lawrence, 1954). In two individuals, Bordley and Hardy (1937) found average losses of 12 dB over frequencies ranging from 256 to 4,096 Hz. 10–30 dB loss is quoted by Simpson et al. (1967), and 20–45 dB loss in the speech frequencies by Thorburn (1971). It has been a general view that the hearing loss increases with the size of the perforation, more so it if is located in the postero-inferior quadrant (Mawson, 1962; Simpson et al., 1967; Thorburn, 1971). In a retrospective study of audiograms in 103 cases, Anthony and Harrison (1972) found that the maximum average loss occurred at 250 Hz., the loss being less in ‘small’ perforations (less than 2 mm. diameter) than in large ones, less in perforations touching the manubrium than in those away from it, and also less in perforations of the antero-inferior quadrant than in those in the postero-inferior quadrant.
Bullous myringitis: its relation to sensorineural hearing loss
Authors: Feinmesser R. , Weissel M. J. , Levi H. , Weiss S. 
Published: November 2007

AbstractBullous myringitis is considered to be a self-limiting disease without complications. Clinical evidence has shown it to be frequently accompanied by sensorineural hearing loss, more often than it was thought to be.The case of a 20-year-old girl is presented in whom bullous myringitis was accompanied by transient sensorineural hearing loss. The site of the lesion was determined to be in the cochlea. We determined, with a high degree of certainty, that the causative agent was mycoplasma.
Hearing impairment and facial palsy as initial signs of Wegener's granulomatosis
Authors: Calonius I. H. , Christensen C. K. 
Published: November 2007

SummaryIn two patients with Wegener's granulomatosis, treatment-resistant serous otitis media was followed by unilateral facial nerve palsy. Later both patients developed uraemia due to extracapillary glomerulonephritis. In one of them, who was treated with prednisone and cyclophosphamide, renal function improved, while in the other patient it remained impaired. Both patients suffered lasting hearing impairment in spite of general improvement during the course of the disease. The facial nerve palsy improved slightly in one, while no improvement was seen in the other.The possibility of Wegener's granulomatosis or other autoimmune collagen diseases should be considered in cases of treatment-resistant serous otitis media. Early diagnosis and treatment can possibly save the patient from the lifethreatening consequences of these diseases.
Neuroleptanalgesia in otorhinolaryngology
Authors: Vishwakarma S. K. , Gupta Rajesh 
Published: November 2007

AbstractNEUROLEPTANALGESIA is described for its use in the management of otolaryngologic cases undergoing elective surgery. 100 cases have been reviewed extensively. The advantages and possible problems are outlined. It seems to be a highly satisfactory alternative to conventional general anesthetic techniques for most ear, nose and throat procedures and operations, where quiescence rather than anesthesia is required. The absence of direct myocardial depression and a marked decrease in operative and post-operative morbidity constitute the principal advantages.
A preliminary report on the combination of initial chemotherapy and radiotherapy for advanced head and neck cancer
Authors: Sergeant R. , Deutsch G. 
Published: November 2007

AbstractA Retrospective review of 45 patients with advanced squamous cell carcinoma of the head and neck treated by a combination of initial chemotherapy (Price and Hill Schedule A) followed by radiotherapy is presented. The regime produced excellent immediate palliation with a tumour control of 50 per cent, and a disease-free survival of 33 per cent at one year and 27 per cent at two years. Treatment morbidity was minimal in an aged patient group.
Tympanic plethysmography in glomus jugulare tumours
Authors: Tewfik Sayed 
Published: November 2007

SummaryTympanic plethysmography is a simple non-invasive diagnostic technique which is used to differentiate between intra-temporal carotid aneurysms and glomus jugulare tumours and to predict the degree of extension of the tumour. It is performed by the indirect recording of volume pressure changes of pulsating tympanic masses using a pressure transducer. The volume pressure change of the pulsating mass is transmitted to the pressure transducer through a saline-filled system.Medical technology has undergone considerable progress with the introduction of new techniques in medical diagnosis less harmful to the patient and with a reduced risk of complications. The collaboration of doctors, scientists and bioengineers has resulted in the evolution of such changes, thereby trying to replace the more aggressive or invasive diagnostic techniques. The ideal diagnostic technology is one without pain, harm or complications to the patient.Medical diagnostic technology may be classified as invasive or noninvasive. Non-invasive diagnostic technology is either active, using an external source of energy such as ultrasound (ultrasonography) or a small dose of X-rays, as in computerized axial tomography; or passive, using the energy emitted by human structures, as in plethysmography.Plethysmography is the recording of volume pressure changes. Oculoplethysmography is used to monitor extracranial occlusive carotid disease (Kartchner and McRae, 1973). The use of sound energy as an internal energy emitted by the human body has proved effective as a passive, non-invasive diagnostic technique (Tewfik, 1976, 1977).Volume pressure changes of intra-temporal carotid aneurysms have been recorded, using a pressure transducer (Tewfik, 1974).In this article the volume pressure changes of glomus jugulare tumours have been recorded and the findings compared with those obtained, and previously published, for intra-temporal carotid aneurysms. Volume pressure changes of pulsating tympanic masses may be called tympanic plethysmography. A trial of this simple non-invasive diagnostic technique for differentiating pulsating tympanic masses is here reported, together with an assessment of the technique in its ability to predict the degree of extension of glomus jugulare tumours.

Published: November 2007

SummaryThe light microscopic and ultrastructural features of a laryngeal salivary duct carcinoma are presented. By light microscopy, the neoplasm bore a marked resemblance to the infiltrating duct carcinoma of the breast. Ultrastructurally, the tumour was characterized by the presence of two principal types of cells, i.e. epithelial and myoepithelial cells, arranged in duct-formation.
Comparison of pre- and post-operative bacteriology of chronic ears
Authors: Ojala Kauko , Sorri Martti , Rihikangas Pauli , Sipilä Pekka 
Published: November 2007

AbstractThe over-all distribution of the pre-operative bacteria of 806 ears and the post-operative bacteria of 109 post-operatively moist or discharging ears correlated very well, the only clear difference being the detection of diphtheroid bacilli more often post-operatively than pre-operatively.When comparing the pre- and post-operative bacteriology of 109 post-operatively infected chronic ears which had undergone radical surgery and obliteration with Palva flaps (and which were drawn from a group of 806 ears originally operated on and followed yearly for 5–14 years) it was noticed that Pseudomonas aeruginosa and Proteus sp were cultured more often post-operatively than pre-operatively in the same ears. Statistically, other bacteria were not found to be significantly present in the same ears.
Rhinomanometry and septoplasty
Authors: Nicklasson Børre , Sundén Lars 
Published: November 2007

Abstract36 Patients showing increased nasal resistance were investigated before and after septoplasty. A simple method of evaluating the rhinomanometric curve has been applied. The patients were operated on consecutively in 1978–79 by the authors. Three months after operation they were followed up regarding nasal anatomy and nasal resistance. The investigation shows that this method may be of value in selecting patients suitable for septoplasty.

Authors: Aghadiuno P. U. , Thomas S. M. , Ogan O. , Martinson F. D. , Adeloye Adelola 
Published: November 2007

SummaryThe case is described of an eight-year-old Nigerian boy who died from olfactory neuroblastoma which presented with nasal obstruction and epistaxis. Autopsy showed intracranial extension of the tumour into the frontal lobe, and histology revealed undifferentiated neuroblasts, forming rosette in some areas and producing tangled neurofibrils in others. The histogenesis of the tumour and its diagnosis are briefly discussed.
Otoscopy compared with tympanometry
Authors: Gimsing Steen , Bergholtz Lars M. 
Published: November 2007

AbstractA study comparing otoscopy with tympanometry was carried out in 1702 ears in seven- and ten-year-old children. Pneumatic otoscopy in 917 ears showed an 88 per cent agreement with tympanometry. The agreement was better in ears considered normal by the otoscopist than in ears that were considered abnormal. Furthermore, the accuracy of otoscopy was better in the older children than in the younger ones.A procedure employing simple otoscopy in 785 ears gave an 83 per cent agreement, but in about 15 per cent of these ears the examiner felt unable to base his evaluation on certainty.It was found that a middle-ear pressure of –100 mm. H2O correlated with recognizable pathology when pneumatic otoscopy was performed.
Phonocephalography and pulsatile tinnitus in a surface cerebral angioma
Authors: Tewfik Sayed 
Published: November 2007

AbstractPhonocephalography is a simple, passive non-invasive diagnostic technique in tinnitus and cerebral angiology.Pulsatile tinnitus may occur in hypertension, haemodynamic disorders, or extracranial and intracranial vascular abnormalities. It is ignored by otologists and neurologists. Phonocephalography is the amplification and recording of sounds from the surface and cavities of the head. In this case report, the technique of phonocephalography was used to records these sounds and the tinnitus in a case of surgace cerebral angioma.
Evaluation of CT in the diagnosis of congenital choanal atresia
Authors: Hasegawa M. , Oku T. , Tanaka H. , Watanabe I. , Suzuki S. 
Published: November 2007

AbstractA six-year-old female with congenital bilateral choanal atresia was examined by CT (computed tomography) and contrast radiography. CT clearly demonstrated the existence of choanal atresia, and differentiated osseous stenosis from membranous stenosis in the choanae. CT may be the first choice of radiological examination for the pre-operative diagnosis of congenital choanal atresia.
Functional voice disorders
Authors: Bridger M. W. M. , Epstein Ruth 
Published: November 2007

AbstractThe records of 109 patients, presenting with functional voice disorder during the years 1977–1981, have been reviewed. The mean age was 45 years and the F: M ratio is 2: 1. Excess voice use was not obviously an aetiological factor. Sixty-one of the 109 patients (56 per cent) were cured by speech therapy, in that their voices returned to their pre-morbid state, and a further 28 (26 per cent) were improved by therapy; seven patients (6 per cent) did not improve and 13 (12 per cent) were lost to follow-up. Of the patients that were ‘cured’, 54 per cent were discharged after three months' treatment and 72 per cent after six months' treatment. Eight per cent required treatment for more than a year.

Authors: Marks Nicholas J. , Cummings Charles W. 
Published: November 2007

AbstractThe design and use of the levator scapulae flap is reviewed. Particular attention is paid to the blood flow. A description is given of how this flap may be employed to repair smaller defects of the mouth and pharynx. It is used in association with split skin. The use of such a technique is compared to musculo-cutaneous flaps, with particular reference to the skin blood flow.
Carcinoma of the external auditory meatus and middle ear
Authors: Stell P. M. , McCormick M. S. 
Published: November 2007

AbstractA staging system is suggested for carcinomas of the external and middle ear, based on a personal series of 47 patients. Statistical analysis showed that the proposed system was a valid method of identifying significant predictor factors. Other significant predictors of survival were histology, lymph node metastases, and the patients' general condition. Stage-for-stage there was no significant difference in survival between tumours of the external and middle ear.

AbstractPrimary Ewing's sarcoma of the ethmoid bone has not been previously described. This case presented as a mass at the nasal bridge and posed diagnostic and therapeutic difficulties. The clinical, radiological, macroscopic and microscopic features are described. The treatment by the combined therapies of cranio-facial resection, radiotherapy and chemotherapy are discussed.
Surgery of sialorrhoea
Authors: Sellars S. L. 
Published: November 2007

SummaryThe drooling that accompanies motor neurone disorders adds to the burden of an individual already severely handicapped socially. Control of this problem can be achieved by a number of measures, such as the surgical repositioning of the salivary gland ducts and by use of medical or surgical means of reducing salivary production.Nineteen patients aged 5 to 9 years, with excessive drooling as a result of perinatal brain damage, have been treated surgically at Groote Schuur Hospital, Cape Town, by bilateral tympanic neurectomies, unilateral chorda tympani nerve section and contralateral submandibular gland excision. In all 19, salivary flow was reduced and the drooling problem significantly improved. No post-operative complications occurred.
The place of ‘salvage’ petrosectomy
Authors: Stell P. M. , Miles J. B. 
Published: November 2007

SummaryThirty-three of 58 patients with carcinoma of the external auditory meatus and middle ear were treated by radiotherapy. Nineteen patients suffered a recurrence. This proved to be unsuitable for petrosectomy in all patients with a tumour of the middle ear. A few patients with tumours of the external auditory meatus, usually of non-squamous variety, have survived for a reasonable period after ‘salvage’ petrosectomy.

Published: November 2007

AbstractEmbolization to treat intractable epistaxis is becoming increasingly popular. Twelve cases of facial nerve paralysis after embolization of branches of the external carotid artery have been reported. In this paper, a new case is reported. In epistaxis. embolization should be reserved for patients with contraindications to ligation or in emergency procedures.
