1.  Sternocostoclavicular hyperostosis presenting with thoracic sinus formation. 
Thorax  1996;51(5):550-552.
Sternocostoclavicular hyperostosis (SCCH) is a condition which is well described in the Japanese literature but is rare in Western Europe. It is characterised by pain and swelling in the upper anterior part of the chest, which tends to be progressive. A patient is described with bilateral chronic discharging sinuses over the anterior ends of the clavicles in whom the diagnosis appeared to be one of SCCH.

2.  Treatment of large airway obstruction in lung cancer using expandable metal stents inserted under direct vision via the fibreoptic bronchoscope. 
Thorax  1996;51(3):248-252.
BACKGROUND: Self-expanding metal stents have been used successfully to overcome large airway obstruction due to malignant pulmonary disease. The technique has been modified to place stents under direct vision using the fibreoptic bronchoscope. The effect of this procedure on lung function and patient well being was investigated in a large series of patients. METHODS: Fifty six patients with malignant tracheobronchial tumours were treated for symptoms of life threatening airways obstruction or collapse of a lung by the insertion of an expandable metal stent(s) under local anaesthetic using a fibreoptic bronchoscope. All had inoperable cancer and 33 had relapsed after or failed to respond to radiotherapy, chemotherapy, or surgery. Forty seven had primary bronchial carcinomas and nine had metastases from other tumour sites. All but two patients had the stents inserted at one sitting. Measurements were performed in most of the patients before and after stenting and included objective measures (pulmonary function tests, arterial blood gas tensions) and non-objective measures (patient well being, performance status). RESULTS: Overall, 77% of patients showed symptomatic improvement. In those patients in whom measurements were performed two thirds showed improvement in forced expiratory volume in one second (FEV1), forced vital capacity (FVC), peak expiratory flow rate (PEFR) and arterial oxygen tension (PaO2). Medical Research Council dyspnoea score (MRC), Karnofsky, and visual analogue scores (for both breathing and well being) improved in 81% of patients. There were no perioperative deaths. Fifty one patients have died since the procedure with a mean survival of 77 days (range 1-477), and five patients are still alive after a mean of 207 days (range 135-274). CONCLUSIONS: In suitable patients with either extraluminal or intraluminal tumour, or both, the insertion of expandable metal stents using a fibreoptic bronchoscope and local anaesthetic is a valuable addition to other palliative therapies in the treatment of lung cancer.

3.  Desmoplastic malignant mesothelioma: a review of 17 cases. 
Journal of Clinical Pathology  1992;45(4):295-298.
AIMS: To identify the histological features of desmoplastic mesothelioma, and to determine its incidence and prognosis. METHODS: Two hundred and fifty five cases of malignant mesothelioma were examined over seven years (1982-9) to identify the desmoplastic variant. Sections were cut at 5 microns and stained with haemotoxylin and eosin and with CAM 5.2 (Dakopatts). Asbestos fibre counts were carried out by light microscopy in 14 cases using the potash digestion method. RESULTS: Seventeen cases were identified as desmoplastic mesothelioma giving an incidence of 6.6%. In 11 cases the cell type in more cellular areas was sarcomatous and in six others it was biphasic. The mean survival time from onset of symptoms to death was 5.8 months for the sarcomatous variant and 6.8 months for the biphasic variant. Twelve of 16 patients had had previous occupational exposure to asbestos, ranging from five months to 43 years. The diagnosis of desmoplastic mesothelioma was only accepted if acellular connective tissue comprised 50% or more of the tumour bulk. Also seen was collagen necrosis, anastomosing bands of often hyalinised collagen with a prominent storiform pattern, and where cellular detail was present there were hyperchromatic nuclei. CONCLUSIONS: Desmoplastic mesothelioma is a rare variant of malignant mesothelioma with a storiform collagen pattern, collagen necrosis, bland acellular collagen and focal cytological features of malignancy. Though rare, it is important to recognise this variant and distinguish it from a pleural plaque, nonspecific reactive pleural fibrosis, pleurisy, rheumatoid disease, or, rarely, spindle cell sarcomas.

5.  Severe granulomatous arthritis due to spinous injury by a "sea mouse" annelid worm. 
Journal of Clinical Pathology  1990;43(4):291-294.
A case of destructive arthritis and soft tissue granulomatous inflammation occurred in a 25 year old man who had injured his right index finger while snorkelling in the Mediterranean. It was initially thought that he had fallen on a sea-urchin. He removed some spines at the time of injury but the finger became stiff, swollen, and painful, and after eight months with no symptomatic improvement amputation through the proximal phalanx was performed. Examination showed an exuberant granulomatous and foreign body type inflammation in the dermis and subcutaneous tissues and affecting the bone, with erosion of the cartilaginous surfaces of the proximal interphalangeal joint. Spines present in soft tissue sections contained no calcium but did contain chitin as shown by a von Wisseling reaction for chitosan. It is concluded that the chitinous spines almost certainly came from a sea-mouse (Phylum Annelida, family Aphroditidae). Sea mice are inconspicuous creatures which live on the sea floor and which may cause some injuries thought to be attributable to sea-urchins.

7.  A study of anal intraepithelial neoplasia in HIV positive homosexual men 
Sexually Transmitted Infections  1999;75(3):172-177.
OBJECTIVES: To determine the prevalence of high grade anal intraepithelial neoplasia (HGAIN), the value of anal cytology in screening for HGAIN, and the characterisation of epidemiological factors and human papillomavirus (HPV) types. METHODS: Prospective cohort study of HIV positive homosexual men. Subjects were interviewed, underwent STD, anal cytological, and HPV screening at enrolment and at subsequent follow up visits with anoscopy and biopsy at the final visit. 57 enrolled, average CD4 count 273 x 10(6)/l (10-588); 41 completed the cytological surveillance over the follow up period (181 visits, average follow up 17 months), 38 of these had anoscopy and anal biopsy. RESULTS: Oncogenic HPV types were detected in 84% and high grade dyskaryosis in 10.5% (6/57) at enrollment. There was a 70% incidence of high grade dyskaryosis during follow up in patients with negative/warty or low grade dyskaryosis at enrollment. Anoscopy correlated with histology in high grade AIN lesions (sensitivity 91%, specificity 54%) and cytology was 78% sensitive (18/23) for HGAIN on biopsy. CONCLUSIONS: AIN and infection with multiple oncogenic HPV types are very common among immunosuppressed HIV positive homosexual men. Apparent progression from low to high grade cytological changes occurred over a short follow up period, with no cases of carcinoma. All 23 cases of HGAIN were predicted by cytology and/or anoscopy. Future studies focusing on the risk of progression to carcinoma are needed before applying anal cytology as a screening tool for AIN in this population.

8.  Tracheal microaspiration in adult cystic fibrosis. 
Gastro-oesophageal reflux (GOR) has been implicated in the aetiology of lung disease. Cystic fibrosis (CF) patients have a high incidence of GOR symptoms with demonstrable episodes of oesophageal acidification. We studied 24-hour ambulatory tracheal and oesophageal pH in 11 CF patients with GOR symptoms to identify any episodes of tracheal acidification and define their temporal relation to oesophageal reflux and respiratory symptoms. 8 patients had evidence of significant GOR (DeMeester score mean 58; range 17-107) and in 6 it was gross (DeMeester score > 30). 4 patients had tracheal acidification (defined as tracheal pH < 5.5): all had greatly raised DeMeester scores. Two patterns of lowered tracheal pH were seen: a gradual drift downwards of tracheal pH to < 5.5 which recovered slowly, and an acute fall in tracheal pH to < 5.5 with rapid recovery. Only one patient had a fall in peak expiratory flow in conjunction with a decline in tracheal pH, and no association was found between the presence of tracheal microaspiration and pulmonary function. We conclude that tracheal acidification occurs in adult CF patients with GOR.

9.  Cross-Polarized Magic-Angle Spinning (sup13)C Nuclear Magnetic Resonance Spectroscopic Characterization of Soil Organic Matter Relative to Culturable Bacterial Species Composition and Sustained Biological Control of Pythium Root Rot 
We report the use of a model system that examines the dynamics of biological energy availability in organic matter in a sphagnum peat potting mix critical to sustenance of microorganism-mediated biological control of pythium root rot, a soilborne plant disease caused by Pythium ultimum. The concentration of readily degradable carbohydrate in the peat, mostly present as cellulose, was characterized by cross-polarized magic-angle spinning (sup13)C nuclear magnetic resonance spectroscopy. A decrease in the carbohydrate concentration in the mix was observed during the initial 10 weeks after potting as the rate of hydrolysis of fluorescein diacetate declined below a critical threshold level required for biological control of pythium root rot. Throughout this period, total microbial biomass and activity, based on rates of [(sup14)C]acetate incorporation into phospholipids, did not change but shifts in culturable bacterial species composition occurred. Species capable of inducing biocontrol were succeeded by pleomorphic gram-positive genera and putative oligotrophs not or less effective in control. We conclude that sustained efficacy of naturally occurring biocontrol agents was limited by energy availability to this microflora within the organic matter contained in the potting mix. We propose that this critical role of organic matter may be a key factor explaining the variability in efficacy typically encountered in the control of pythium root rot with biocontrol agents.

13.  Improved blood culture technique based on centrifugation: clinical evaluation. 
Journal of Clinical Microbiology  1979;9(3):391-396.
A total of 3,335 blood samples from 1,180 patients suspected of having bacteremia were analyzed concurrently by two methods: (i) supplemented peptone broth with sodium polyanethanol sulfonate and a CO2 atmosphere; and (ii) lysis centrifugation at 3,000 X g for 30 min onto a high-density, hydrophobic cushion. The centrifugation technique recovered 80% of the positive cultures as compared with 67% for the broth method. The centrifugation technique showed an apparent increase in the isolation of staphylococcus aureus, Pseudomonas, and yeasts. In almost every instance, the time required for detection of a positive culture was shortest for the centrifugation method. Contamination rates for both systems were comparable (1.4%). Quantitation, offered only by the centrifugation method, proved useful on several occasions in discriminating between an opportunistic infection versus a skin contaminant and in judging efficacy of antimicrobial therapy.
