Published: November 2007

AbstractComplexes of the Alkali Metal Tetraphenylborates with Macrocyclic Crown EthersAlkali metal tetraphenylborates, MB(C6H5)4 (M = Li to Cs), react in tetrahydrofuran with macrocyclic crown ethers to give complexes of the general formula MB(C6H5)4(crown)m(THF)n. Suitable single crystals for X‐ray structure analysis were grown from a solvent mixture of tetrahydrofuran and n‐hexane. The salt like complexes [Li(12‐crown‐4)(thf)][B(C6H5)4] (1), [Na(15‐crown‐5)(thf)][B(C6H5)4] (2), and [Cs(18‐crown‐6)2][B(C6H5)4] · THF (6), the mononuclear molecular complexes [KB(C6H5)4(18‐crown‐6)(thf)] (3), [RbB(C6H5)4(18‐crown‐6)] (4), and [CsB(C6H5)4(18‐crown‐6)] · THF (5), and the compound [CsB(C6H5)4(18‐crown‐6)]2[Cs(18‐crown‐6)2][B(C6H5)4] (7), which contains a binuclear molecule ([CsB(C6H5)4(18‐crown‐6)]2) beside a [Cs(18‐crown‐6)2]+ cation and a [B(C6H5)4]− anion, are described. All compounds are charactarized by infrared spectra, elemental analysis, NMR‐spectroscopy, and X‐ray single crystal structure analysis.

AbstractSyntheses, Structure and Reactivity of η3‐1,2‐Diphosphaallyl Complexes and [{(η5‐C5H5)(CO)2W–Co(CO)3}{μ‐AsCH(SiMe3)2}(μ‐CO)]Reaction of ClP=C(SiMe2iPr)2 (3) with Na[Mo(CO)3(η5‐C5H5)] afforded the phosphavinylidene complex [(η5‐C5H5)(CO)2Mo=P=C(SiMe2iPr)2] (4) which in situ was converted into the η1‐1,2‐diphosphaallyl complex [η5‐(C5H5)(CO)2Mo{η3‐tBuPPC(SiMe2iPr)2] (6) by treatment with the phosphaalkene tBuP=C(NMe2)2. The chloroarsanyl complexes [(η5‐C5H5)(CO)3M–As(Cl)CH(SiMe3)2] [where M = Mo (9); M = W (10)] resulted from the reaction of Na[M(CO)3(η5‐C5H5)] (M = Mo, W) with Cl2AsCH(SiMe3)2. The tungsten derivative 10 and Na[Co(CO)4] underwent reaction to give the dinuclear μ‐arsinidene complex [(η5‐C5H5)(CO)2W–Co(CO)3{μ‐AsCH(SiMe3)2}(μ‐CO)] (11). Treatment of [(η5‐C5H5)(CO)2Mo{η3‐tBuPPC(SiMe3)2}] (1) with an equimolar amount of ethereal HBF4 gave rise to a 85/15 mixture of the saline complexes [(η5‐C5H5)(CO)2Mo{η2‐tBu(H)P–P(F)CH(SiMe3)2}]BF4 (18) and [Cp(CO)2Mo{F2PCH(SiMe3)2}(tBuPH2)]BF4 (19) by HF‐addition to the PC bond of the η3‐diphosphaallyl ligand and subsequent protonation (18) and/or scission of the PP bond by the acid (19). Consistently 19 was the sole product when 1 was allowed to react with an excess of ethereal HBF4. The products 6, 9, 10, 11, 18 and 19 were characterized by means of spectroscopy (IR, 1H‐, 13C{1H}‐, 31P{1H}‐NMR, MS). Moreover, the molecular structures of 6, 11 and 18 were determined by X‐ray diffraction analysis.
Diverse Coordinative Functions of 4,4′‐Bipyridine Generating Abundant Weak Interactions and Novel Fluorescent Property in Cadmium(II)‐4‐sulfobenzoate Polymer
Authors: Zhang Li‐Ping , Zhu Long‐Guan 
Published: November 2007

AbstractThe cadmium(II) 4‐sulfobenzoate complex with 4,4′‐bipyridine, {[Cd2(4,4′‐bipy)4(4‐sb)2(H2O)3] · 4H2O}n, has been synthesized and characterized by elemental analysis, IR, DTA‐TG, fluorescence analysis, powder X‐ray analysis, and single‐crystal X‐ray structural determination. Structural analysis showed that the complex contains two Cd atoms in an unsymmetrical unit. The Cd1 atom displays a seven‐coordinated geometry, which is a capped anti‐trigonal prismatic structure, whereas the Cd2 atom has an octahedral coordination. The 4,4′‐bipyridine ligands in the complex have three coordination behaviors, i.e., monodentate, dimeric linker, and polymeric bridge, which is the first example showing three coordinative functions for 4,4′‐bipyridine ligands in one complex. Moreover, three coordinative functions of 4,4′‐bipyridine ligands in this polymer lead to abundant weak interactions and novel fluorescent properties, which is benefit for design and preparation of functional materials in specific usage.

Published: November 2007

AbstractBackgroundRecently there has been a renewed interest in defining the boundaries and subdomains of the negative syndrome in schizophrenia and new scales have been asked for. Apathy is one of the symptoms in focus. The Apathy Evaluation Scale (AES) with its clinical version (AES-C) is one of the most used scales in an interdisciplinary context, but it has never previously been used in a population with first episode psychosis. The main aims of this study were to examine the psychometric properties of the AES-C and its relationship to the Positive and Negative Syndrome Scale (PANSS).MethodsA total of 104 patients with first episode psychosis from the ongoing Thematic Organized Psychosis Research (TOP) study were included.ResultsA factor analysis of the AES-C identified three subscales: Apathy, Insight and Social Contacts. Only the Apathy subscale showed satisfactory psychometric properties and showed acceptable convergent and discriminate properties by correlating strongly with the apathy-related items of the PANSS.ConclusionsThis study shows that the AES-C measures more than one dimension. The main factor, the Apathy subscale, can however be used to assess apathy in first episode psychosis patients in the ongoing work of refining the subdomains of the negative syndrome.
CONTINUITY, REVOLUTION OR EVOLUTION ON THE SLAVE COAST OF WEST AFRICA? ROYAL ARCHITECTURE AND POLITICAL ORDER IN PRECOLONIAL DAHOMEY
Authors: MONROE J. CAMERON 
Published: November 2007

ABSTRACTThe Kingdom of Dahomey has played a central role in our understanding of political organization in West Africa in the era of the trans-Atlantic slave trade. Research has focused on two major questions: whether or not Dahomey possessed revolutionary qualities that allowed it to maintain order in this turbulent era, and the role of militarism in fostering stability. Mounting archaeological evidence from the Republic of Bénin can contribute to our understanding of Dahomean political dynamics over time. Spatial patterns in royal palace construction, materialized regionally and architecturally, are examined in this essay. These data suggest that Dahomey achieved real administrative advances in the eighteenth and nineteenth centuries, including the expansion of regional control and the successful integration of a complex administrative hierarchy.1
TOM AND TOAKAFO: THE BETSIMISARAKA KINGDOM AND STATE FORMATION IN MADAGASCAR, 1715–1750
Authors: ELLIS STEPHEN 
Published: November 2007

ABSTRACTThe monarchies and other polities of precolonial Madagascar exerted a strong influence on each other. For this reason, in recent years it has become more interesting to trace their inter-relationship than to emphasize their autonomy. The Betsimisaraka kingdom, which flourished on Madagascar's east coast in the early eighteenth century, has generally been regarded as a polity standing rather outside the mainstream of state formation in Madagascar, not least because of the identity of its founder, the son of an English pirate. Research in European and South African archives demonstrates the close connection between the Betsimisaraka kingdom and the Sakalava kingdom of Boina.
Behc¸et's disease of the oesophagus
Authors: Levack B. , Hanson D. 
Published: November 2007

AbstractA FORTY-TWO-YEAR-OLD man known to have Behçet's disease (two major and two minor symptoms) (Mason and Baines, 1969) presented with dysphagia, hoarseness and regurgitation of food. This was subsequently found to be due to a tracheo-oesophageal fistula consequent upon an area of Behçet's ulceration in the oesophagus. The fistula was excised, the defects in the trachea and oesophagus repaired, and the patient's recovery was uneventful.
Submucous resection

Published: November 2007

AbstractThe combination of nasal septal deviation and Eustachian tube dysfunction, in the absence of any other pathology, constitutes the Nose–Ear Distress Syndrome.We have undertaken a clinical assessment of the relationship between uncomplicated deviation of the nasal septum and Eustachian tube dysfunction in Naval Personnel who are serving in environments of primarily increased barometric pressure.120 candidates to the Submarine, Diving and Aircrew branches of the Royal Navy who presented with the Nose–Ear distress syndrome were initially surveyed. None were able to equilibrate their middle ear pressures at an increased ambient pressure of 3 metres of water. Submucous resection was performed on 116, of whom 110 (94·83 per cent) were able to equilibrate their middle ear pressures at an increased ambient pressure of 9 metres of water post-operatively.Xenon 133 Scintigraphy was performed on a further 25 recruits to delineate the post-nasal airflow. This investigation was performed pre- and post-operatively. Pre-operatively, Scintigraphy showed the presence of turbulence in the post-nasal space, while post-operatively the turbulence was absent. All the candidates were unable to equilibrate their middle ear pressures pre-operatively, but after submucous resection 24 (96 per cent) were able to equilibrate their middle ear pressures at an increased barometric pressure of 9 metres of water.
Hyoid bone fracture with pharyngeal lacerations

Published: November 2007

AbstractFour cases of hyoid bone fracture with laceration of the pharynx are presented. The emergency treatment must aim at an exploration of the neck in an attempt to suture the lacerations of the pharyngeal musosa.The fractured hyoid bone may be left untouched in most cases.The most common causes of fractures of the hyoid bone were previously considered to be violent strangulation and hanging.In the last two decades however, road accidents seem to have become the most important cause in patients who survive the initial impact of collision.The biodynamics of injury to the pharynx and larynx in road accidents hava been adequately described by Nahum and siegel(1967). They concluded that the driver was the most commonly collides.It is very easy to miss a fractured hyoid bone duing the urgent admission of a patient injured in a accident, since the more dramatic injures in a traffic in a traffic accident, since the more dramatic injuries are treated first and and a tracheostomy is often often perfomed to provide an airway.
The changing pattern of laryngeal tuberculosis
Authors: Hunter A. M. , Millar J. W. , Wightman A. J. A. , Horne N. W 
Published: November 2007

SummaryLaryngeal tuberculosis is now an uncommon disease in the United Kingdom. A series of ten cases is reported. In contrast to the pre-chemotherapy era, when the disease was associated with advanced cavitated pulmonary tuberculosis and was highly infectious, it now presents in a manner similar to laryngeal carcinoma except that painful dysphagia is a prominent symptom. All such patients should have a chest X-ray carried out as part of their initial investigation. Sputum is almost always positive for tubercle bacilli on direct films. Direct laryngoscopy and biopsy are necessary if a carcinoma is suspected.The change of pattern of the disease may be due to the fact that the larynx now usually becomes involved by haematogenous spread rather than by direct spread along the airways. Laryngeal tuberculosis is now no more infectious than pulmonary tuberculosis, and responds well to antituberculous chemotherapy. Symptoms resolve completely within three weeks if corticosteroids are given in combination.
Transcranial attenuation in bone conduction audiometry
Authors: Nolan Michael , Lyon David J. 
Published: November 2007

AbstractTranscranial attenuation for bone conduction as a function of frequency (0.25 to 4 kHz.) was measured on a group of unilaterally deaf (n 15) and a group of normal (n = 35) ears. The results indicate a positive mean attenuation for all frequencies with a peak value of 13 db. for both groups at 2 kHz. Inter-subject variability was extremely large. This is considered to be a result of variability in skull bone thickness.
The diagnosis and surgical management of olfactory neuroblastoma: The role of craniofacial resection
Authors: Chapman P. , Carter R. L. , Clifford P. 
Published: November 2007

SummaryThe diagnosis and clinical management of olfactory neuroblastoma are discussed. Computerized tomography is a valuable means of assessing the pre-operative extent of disease and the efficacy of subsequent major surgery. The tissue diagnosis is facilitated by electron microscopy, demonstrating the presence of dence core vesicles and cytoplasmic filaments. Radiotherapy followed by craniofacial resection is the treatment of choice for olfactory neuroblastomas that are locally extensive at presentation.
Studies on the production of middle-ear effusion in the experimental animal
Authors: Khan Jamsheed A. , Campbell John C. 
Published: November 2007

AbstractMiddle-ear effusions have been produced following eustachian tube obstruction in guinea pigs. This was achieved by plugging the pharyngeal orifice of the tube by an atraumatic lateral transpalatal incision. General anaesthesia was used throughout the entire procedure. The presence of fluid in the middle-ear cavity was determined by observing:(a) The appearance of pallor of the drum.(b) Retraction of the tympanic membrance.(c) Cloudiness of the tympanic bullae on radiographs obtained at weekly intervals, confirmed by:(d) Subsequent myringotomy.Serial smears of the induced effusions showed an absence of chronic inflammatory cells except in the case of one animal which developed bacterial otitis media. The presence of secretory cells was demonstrated in the actual epithelial layer and lamina propria but no discrete glands were found. Squamous metaplasia of the lining of the middle-ear cleft was noted. The fluid from the tympanic cavity appeared watery, faintly turbid and non-mucoid, and resembled the serious type of effusion found in man.
Uvulectomy in Nigeria
Authors: Ijaduola G. T. A. 
Published: November 2007

AbstractThe removal of the uvula for minor pharyngeal lesions is unusual in Western otorhinolaryngological practice. However, uvulectomy is a common procedure for ‘throat problems’ in Nirgeria and some other African countries by traditional surgeons. This is because it is believed that the elongated uvula is the root cause of all throat problems. These traditional surgeons are usually barbers by profession and only practice surgery on a part-time basis. Most of their patients do well but some have to be rushed to the hospital with severe post-operative bleeding. Attention of Europeans and other foreign otolaryngologists who may find themselves practising in any part of Arica is hereby drawn to the procedure.
Candida tropicalis meningitis: a case report
Authors: Chattopadhyay B. 
Published: November 2007

SummaryA 54-year-old man presented with candida tropicalis meningitis after exploration of the mastoid. He responded well to the combined intravenous administration of amphotericin B and 5 fluorocytosine. But 5 fluorocytosine had to be withdrawn when the candida proved to be resistant to this antifungal agent. However, the patient made an uneventful recovery. This seems to be the first report of a candida tropicalis meningitis in an otherwise healthy adult patient in this country.Infection of the meninges with candida remains rare (Black, 1970). Most of them are caused by candida albicans in patients with some other underlying conditions or those on prolonged antibiotic, corticosteroid, cytotoxic, immunosuppresive therapies. The purpose of this brief communication is to draw attention to its occurrence in a healthy patient following exploration of the mastoid for chronic suppurative middle-ear disease.
Tympanic membrane grafting with fascia, pericardium and vein
Authors: Hordijk Gerrit J. , Rietema Sietze J. 
Published: November 2007

summaryFascia and preserved homologous vein and pericardium have been used in consecutive order in 250 ear operations. Though successful closure of the defect, in cases with chronic ear infection, tended to be better with pericardium, auditory gain with pericardium seemed to be less than with fascia and vein. The differences, however, were not statistically significant. For the reason that it is easier to obtain, vein is the graft of choice in our institution when homologous graft is needed.
The treatment of head and neck carcinoma with Adriamycin and Belomycin using adjuvant hyperthermia
Authors: Fairman H. D. 
Published: November 2007

SummaryTwenty-two cases of carcinoma of the head and neck (predominantly squamous), in a veriety of sites, were treated with an oncolytic regime of Adriamycin and Bleomycin. Adjuvant hyperthermia was given to all cases; differing techniques of drug administration were used, depending on whether a case had received previous irradiation. Twenty-one cases showed response to treatment. Post-irradiation cases fared less well than those in which radiotherapy was synchronised with treatment.

Authors: Laskiewicz B. M. 
Published: November 2007

SummaryThis paper describes the management of patients undergoing synchronous combined chemotherapy and radiotherapy at King's College Hospital. It is based on the experience of treating 96 patients with carcinoma of the head and neck between 1974–1978.A detailed account is given of the method of conducting the treatment. The routine assessment, investigations and follow-up are described, together with the complications due to individual drugs and general effects of combined therapy and their management. Great stress is laid on the need for active, intensive nursing care of these patients.
Results of surgery for nasal dermoids in children
Authors: Bradley P. J. 
Published: November 2007

SummaryThirty-Two patients who had surgical excision of a nasal dermoid in child-hood are reported. The patients are discussed according to the histological diagnosis and the extent of tissue involvement at the time of surgery. The results of surgery are acceptable in the majority of patients. However, a patient with a ‘complex’ ‘true’ nasal dermoid lesion is more likely to be dis-satisfied with the result of surgical excision. Parents should therefore be forewarned of the possible outcome of surgery for nasal for dermoid lesions in children.
Pathology as it relates to ear surgery
Authors: Belal A. , Sanna M. 
Published: November 2007

AbstractSurgery is the treatment of choice in the management of glomus tumours. There are several different approaches to the surgical excision of these tumours, the choice depending on the size, site of origin and pattern of spread of the tumour. The patterns of glomus tumour invasion in the temporal bone are demonstrated by reviewing the histological findings in four temporal bones with glomus tumours. The surgical techniques used in the management of 14 glomus tumours are also discussed.

Lactate dehydrogenase in human maxillary adenocarcinoma and in experimental adenocarcinoma in mice
Authors: Gołabek Wiesław , Franks Leonard M. 
Published: November 2007

Total lactate dehydrogenase (LDH) activity and isoenzyme pattern were studied in tumore tissue from eight patients with maxillary adenocarcinoma, chronic inflammatory mucosa from 12 patients, normal maxillary mucosa from 12 patients, and an experimental lung adenocarcinoma and normal lung tissue from 12 mice.An increase in the total LDH activity and cathodic shift in LDH isoenzyme pattern was found in human maxillary adenocarcinoma as compared to normal and inflammatory mucosa. The inflammatory mucosa showed an increase in the total LDH activity and a normal isoenzyme pattern. The LDH alterations in the total LDH activity and a normal isoenzyme pattern. The LDH alterations in the experimental lung adenocarcinoma in mice were similar to those in the human tumours but they were much more marked.

Published: November 2007

SummaryThe clinical aspects of mycobacterial infection of the head and neck are considered as presenting in patients at a cancer hospital over the last 15 years. Some difficulties in diagonsis with respect to the evalution of tuberculosis in this region are discussed.A total of 32 patients with evidence of infection were identified. Twenty-six of these with cervical lymphadenopathy are considered as a group; their clinical features and diagonsis are summarized and a note made of the recent change in the macroscopic quality of the notes removed.Six cases are given particular attention; two with laryngeal, two with nasal or adenodial infection and two with atypical mycobacterial infection diagnosed on clinical grounds.

AbstractReports of tracheopathia osteoplastica localized to the larynx are few. Such a rare case is reported in a 66-year-old mald with life-long symptoms resulting in tracheotomy and resection of some of the osteoplastic tissue. A review of the disease and a discussion about actiology are described.
The investigation and management of petrous apex ersion
Authors: Flood L. M. , Kemink J. L. , Graham M. D. 
Published: November 2007

AbstractDisease of the apex of the petrous temporal bone, while rarely encountered, can present a unique challenge to the otologist. Lesions tend to be advanced at presentation, as massive bony erosion can remain asymptomatic. When symptoms occur, they reflect involvement of the neurovascular contents of the temporal bone. The earliest clinical features, such as headache, facial numbness and middle-ear effusion, do not immediately suggest the site or gravity of the underlying pathology. Anterior extension of disease may produce ophthalmoplegia and diplopia whilst posterior spread involves the lower cranial nerves, within the internal auditory canal, jugular foramen and hypoglossal canal.
Unusual sites of schwannoma in the head and neck

Published: November 2007

AbstractTwo cases of schwannoma originating in unusual sites in the head and neck are reported. To the best of our knowledge ours is the first case of schwannoma in the nasopharyngeal area to be described. Schwannomas in the parotid area must be kept in mind in the differential diagnosis of parotid tumours. The pertinent literature is reviewed.
The importance of nasal fractures during different growth periods of the nose
Authors: Grymer Luisa F. , Gutierrez Carolina , Stoksted Poul 
Published: November 2007

SummaryFifty-seven patients who had sustained nasal fractures during childhood were divided into three groups, according to the age at which the fracture had taken place. These three groups were based on the normal periods of development of the nose. They were compared with regard to possible sequelae after fracture. The results are discussed and an example from each group is shown.
