Congenital cystic adenomatoid malformation of the lung: indications and timing of surgery

We review a single surgeon and surgical centre's experience with congenital cystic adenomatoid malformation of the lung (CCAML) in relation to clinical spectrum, operative experience, and postoperative course. A retrospective hospital record review was done on surgically treated cases of CCAML over a 10-year period, focusing on number with antenatal diagnosis, spectrum of postnatal presentation, type of surgery performed, and outcome. Forty-seven patients from birth to 14 years of age underwent surgery for CCAML. Antenatal diagnosis (ante) was made in 30 cases. Of these, 10 became symptomatic before surgery. Six of the 17 postnatally-diagnosed (pnd) cases were an asymptomatic incidental finding. Overall, 16 were symptomatic in the 1st year of life, and five were symptomatic beyond 1 year of age. Symptoms varied from respiratory distress (seven ante, six pnd) to chronic cough (three, and recurrent chest infection (three ante, two pnd). All preoperative diagnoses were confirmed with chest CT. Most patients (25) were operated on before 3 months of age. Eleven were operated on in the first 2 weeks of life as emergency surgery for respiratory distress. The most common lobe involved was the right upper lobe (16), and lobectomy was performed in 42 cases, segmentectomy in four, and pneumonectomy in one. Seventeen cases were extubated immediately postoperatively; 29 required postoperative ventilation overnight, and nine needed more prolonged ventilation. Early postoperative complications included pneumothorax (two), pleural effusion (one), and chylous effusion (one). Late complications included recurrence in three cases (all segmentectomy), who then subsequently underwent lobectomy. There was one death from respiratory failure. Because there is an increasing trend in the detection of asymptomatic antenatally-diagnosed CCAML, consideration of early surgical excision to prevent complications is suggested by our series. CT scanning is mandatory for postnatal evaluation because chest x-ray could be normal. Safe elective excision after 3 months is supported by our low morbidity and less need for postoperative ventilation. Lobectomy is the procedure of choice to prevent recurrence.

Tympanometric norms for Chinese schoolchildren

Current tympanometric norms have acknowledged the relevance of age as,in influencing factor. However, little attention has been afforded to other potentialities such its the non-pathological effects of gender, ear asymmetry, and racial heritage. This study aimed to examine normative tympanometric findings in a large sample of Chinese schoolchildren. Using a Madsen 901 Middle Ear Analyzer, data was collected from 269 children (538 ears), ranging in age from 6.2-12.7 years (mean = 9.4 years, SD = 1.7), in Jiangsu province. Descriptive statistics were calculated for the parameters of equivalent car canal volume (chi = 1.03, SD = 0.25, 90% = 0.68-1.46), peak compensated static acoustic admittance (chi = 0.58, SD = 0.34, 90% = 0.26-1.13), tympanometric width (chi = 112, SD=36, 90% = 62-156), and peak pressure (chi = -25, SD = 30, 90% = -85-+10). Statistically significant car asymmetry and grade/age effects were estabished, although differences found were minor. In comparison with past studies in Caucasian paediatric populations, the Chinese normative data displayed minimal disparities.

Dimeric allylpalladium(II) complexes with pyrazolate bridges: Synthesis, characterization, structure and thermal behaviour

The synthesis, characterization and thermal behaviour of some new dimeric allylpalladium (II) complexes bridged by pyrazolate ligands are reported. The complexes [Pd(mu-3, 5-R'(2)pz)(eta(3)-CH2C(R)CH2)](2) [R = H; R'= CH(CH3)(2) (1a); R = H, R' = C(CH3)(3) (1b), R = H; R' = CF3 (1c); R = CH3, R' = CH(CH3)(2) (2a); R = CH3, R' = C(CH3)(3) (2b); and R = CH3, R' = CF3 (2c)] have been prepared by the room temperature reaction of [Pd(eta(3)-CH2C(R)CH2)(acac)](acac = acetylacetonate) with 3,5-disubstituted pyrazoles in acetonitrile solution. The complexes have been characterized by NMR (H-1, C-13{H-1}), FT-IR, and elemental analyses. The structure of a representative complex, viz. 2c, has been established by single-crystal X-ray diffraction. The dinuclear molecule features two formally square planar palladium centres which are bridged by two pyrazole ligands and the coordination of each metal centre is completed by allyl substituents. The molecule has non-crystallographic mirror symmetry. Thermogravimetric studies have been carried out to evaluate the thermal stability of these complexes. Most of the complexes thermally decompose in argon atmosphere to give nanocrystals of palladium, which have been characterized by XRD, SEM and TEM. However, complex 2c can be sublimed in vacuo at 2 mbar without decomposition. The equilibrium vapour pressure of 2c has been measured by the Knudsen effusion technique. The vapour pressure of the complex 2c could be expressed by the relation: In (p/Pa)(+/- 0.06) = -18047.3/T + 46.85. The enthalpy and entropy of vapourization are found to be 150.0 +/- 3 kJ mol(-1) and 389.5 +/- 8 J K-1 mol(-1), respectively. (c) 2005 Elsevier B.V. All rights reserved.

Segmental lung lobe torsion in a 7-week-old Pug

Case summary: A 7-week-old, intact female Pug was referred with an acute history of expiratory dyspnea, tachypnea, and pyrexia. Radiologic evaluation revealed bilateral pleural effusion and a poorly demarcated area of soft tissue opacity cranial to the heart. The presence of air bronchograms in the cranial lung lobes suggested alveolar parenchymal pathology consistent with pulmonary edema, congestion, or cellular infiltration. Exploratory thoracotomy revealed a segmental torsion of the left cranial lung lobe. The affected lobe was removed and the puppy recovered uneventfully. Unique information: Lung lobe torsion tends to occur more frequently in mature large breed dogs at a mean age of 3 years. The age, breed, and segmental nature of the torsion in the reported case are contrary to most of the previously documented cases of lung lobe torsion. To the authors' knowledge, this is the first report of lung lobe torsion in a 7-week-old dog.

Successful management of lymphangiomatosis and chylothorax in a 7-month-old infant

A 7-month old infant presented with an effusion and multiple lesions in his spleen. A diagnosis of lymphangiomatosis was made based on chylous effusion and an MRI demonstrating numerous enhancing lesions within the spleen on T2-weighed images. Conservative measures, including the withdrawal of feeds and octreotide, did not significantly reduce the rate of chyle production and increasing requirement for respiratory support. Resection of the patient's spleen and partial pleurectomy were associated with a dramatic improvement in his condition. At 27 months the patient was well with no evidence of further lymphangiomas or a recurrence of his chylothoraces.

A combined spectrophotometric and morphometric study of the lunar mare dome fields near Cauchy, Arago, Hortensius, and Milichius

In this Study we examine the spectral and morphometric properties of the four important lunar mare dome fields near Cauchy, Arago, Hortensius. and Milichius. We utilize Clementine UV vis mulfispectral data to examine the soil composition of the mare domes while employing telescopic CCD imagery to compute digital elevation maps in order to determine their morphometric properties, especially flank slope, height, and edifice Volume. After reviewing previous attempts to determine topographic data for lunar domes, we propose an image-based 3D reconstruction approach which is based on a combination of photoclinometry and shape from shading. Accordingly, we devise a classification scheme for lunar Marc domes which is based on a principal component analysis of the determined spectral and morphometric features. For the effusive mare domes of the examined fields we establish four Classes, two of which are further divided into two subclasses, respectively, where each class represents distinct combinations of spectral and morphometric dome properties. As a general trend, shallow and steep domes formed out of low-TiO2 basalts are observed in the Hortensius and Milichius dome fields, while the domes near Cauchy and Arago that consist of high-TiO2 basalts are all very shallow. The intrusive domes of our data set cover a wide continuous range of spectral and morphometric quantities, generally characterized by larger diameters and shallower flank slopes than effusive domes. A comparison to effusive and intrusive mare domes in other lunar regions, highland domes, and lunar cones has shown that the examined four mare dome fields display Such a richness in spectral properties and 3D dome shape that the established representation remains valid in a more global context. Furthermore, we estimate the physical parameters of dome formation for the examined domes based on a rheologic model. Each class of effusive domes defined in terms of spectral and morphometric properties is characterized by its specific range of values for lava viscosity, effusion rate, and duration of the effusion process. For our data set we report lava viscosities between about 10(2) and 10(8) Pas, effusion rates between 25 and 600 m(3) s(-1), and durations of the effusion process between three weeks and 18 years. Lava viscosity decreases with increasing R-415/R-750 spectral ratio and thus TiO2 content; however, the correlation is not strong, implying an important influence of further parameters like effusion temperature on lava viscosity.

Comparison of surfactant lipids between pleural and pulmonary lining fluids

Saturated phospholipids (PCs), particularly dipalmitoylphosphatidylcholine (DPPC), predominate in surfactant lining the alveoli, although little is known about the relationship between saturated and unsaturated PCs on the outer surface of the lung, the pleura. Seven healthy cats were anesthetized and a bronchoalveolar lavage (BAL) was performed, immediately followed by a pleural lavage (PL). Lipid was extracted from lavage fluid and then analyzed for saturated, primarily dipalmitoylphosphatidylcholine (DPPC), and unsaturated PC species using high-performance liquid chromatography (HPLC) with combined fluorescence and ultraviolet detection. Dilution of epithelial lining fluid (ELF) in lavage fluids was corrected for using the urea method. The concentration of DPPC in BAL fluid (85.3 +/- 15.7 mu g/mL) was significantly higher (P=0.021) than unsaturated PCs (similar to 40 mu g/mL). However, unsaturated PCs (similar to 34 mu g/mL), particularly stearoyl-linoleoyl-phosphatidylcholine (SLPC; 17.4 +/- 6.8), were significantly higher (P = 0.021) than DPPC (4.3 +/- 1.8 mu g/mL) in PL fluid. These results show that unsaturated PCs appear functionally more important in the pleural cavity, which may have implications for surfactant replenishment following pleural disease or thoracic surgery.

Structural and cellular characterization of Idiopathic Pulmonary Fibrosis

La Fibrosi Polmonare Idiopatica (IPF) è una malattia polmonare cronica, irreversibile la cui eziologia risulta essere ignota, caratterizzata da un processo fibrotico progressivo che inizia nel tratto respiratorio inferiore. Le persone affette da IPF presentano età media compresa tra 55 e 77 anni. L’incidenza annuale di IPF è stata recentemente stimata tra 14 e 42,7 casi per 100.000 persone e tale dato risulta essere in aumento. IPF fa parte delle malattie Polmonari Idiopatiche Interstiziali (IIP) che comprendono patologie con quadri istologici e clinici differenti. Le affezioni su cui si concentrerà questo studio sono: UIP (Usual Interstitial Pneumonia) caratterizzata da fibrosi interstiziale e dalla presenza di foci fibrotici connessi alla pleura e corrispondente al quadro anatomopatologico della maggior parte dei casi di IPF; NSIP (Non Specific Interstitial Pneumonia) simile alla UIP ma con maggiore uniformità temporale e spaziale delle manifestazioni; Sarcoidosi, malattia granulomatosa ad eziologia ignota. Attualmente la gravità della IPF, che implica una mortalità del 50% dei pazienti a 5 anni dall’esordio, e la scarsa efficacia farmacologica nel rallentarne la progressione vedono il trapianto polmonare come unica possibilità di sopravvivenza nelle forme più severe. Al momento non è chiaro il meccanismo patogenetico di insorgenza e progressione della IPF anche se sono stati individuati alcuni fattori scatenanti quali fumo di sigaretta, infezioni respiratorie e inquinanti atmosferici; tuttavia nessuno di tali elementi può da solo determinare un così esteso e progressivo rimodellamento del parenchima polmonare. Numerose sono le evidenze di come il substrato genetico, le alterazioni del rapporto morte/proliferazione cellulare e le citochine svolgano un ruolo nella genesi e nella progressione della malattia, ma non sono ancora chiari i fenomeni biologico-cellulari che la sostengono e, quindi, quali siano i punti di attacco per poter incidere terapeuticamente nel modificare l’evoluzione della IPF. Poiché il nostro laboratorio ha partecipato alla scoperta dell’esistenza di cellule staminali nel polmone umano normale, uno degli obiettivi finali di questo progetto si basa sull’ipotesi che un’alterazione del compartimento staminale svolga un ruolo cruciale nella eziopatogenesi di IPF. Per questo in precedenti esperienze abbiamo cercato di identificare nella IPF cellule che esprimessero antigeni associati a staminalità quali c-kit, CD34 e CD133. Questo lavoro di tesi si è proposto di condurre un’indagine morfometrica ed immunoistochimica su biopsie polmonari provenienti da 9 pazienti affetti da UIP, 3 da NSIP e 5 da Sarcoidosi al fine di valutare le alterazioni strutturali principali imputabili alle patologie. Preparati istologici di 8 polmoni di controllo sono stati usati come confronto. Come atteso, è stato osservato nelle tre patologie esaminate (UIP, NSIP e Sarcoidosi) un significativo incremento nella sostituzione del parenchima polmonare con tessuto fibrotico ed un ispessimento dei setti alveolari rispetto ai campioni di controllo. L’analisi dei diversi pattern di fibrosi presenti fa emergere come vi sia una netta differenza tra le patologie con una maggiore presenza di fibrosi di tipo riparativo e quindi altamente cellulata nei casi di UIP, e NSIP mentre nelle Sarcoidosi il pattern maggiormente rappresentato è risultato essere quello della fibrosi replacement o sostitutiva. La quantificazione delle strutture vascolari è stata effettuata tenendo separate le aree di polmone alveolare rispetto a quelle occupate da focolai sostitutivi di danno (componente fibrotica). Nei campioni patologici analizzati era presente un significativo riarrangiamento di capillari, arteriole e venule rispetto al polmone di controllo, fenomeno principalmente riscontrato nel parenchima fibrotico. Tali modifiche erano maggiormente presenti nei casi di NSIP da noi analizzati. Inoltre le arteriole subivano una diminuzione di calibro ed un aumento dello spessore in special modo nei polmoni ottenuti da pazienti affetti da Sarcoidosi. Rispetto ai controlli, nella UIP e nella Sarcoidosi i vasi linfatici risultavano inalterati nell’area alveolare mentre aumentavano nelle aree di estesa fibrosi; quadro differente si osservava nella NSIP dove le strutture linfatiche aumentavano in entrambe le componenti strutturali. Mediante indagini immunoistochimiche è stata documentata la presenza e distribuzione dei miofibroblasti, positivi per actina muscolare liscia e vimentina, che rappresentano un importante componente del danno tissutale nella IPF. La quantificazione di questo particolare fenotipo è attualmente in corso. Abbiamo inoltre analizzato tramite immunoistochimica la componente immunitaria presente nei campioni polmonari attraverso la documentazione dei linfociti T totali che esprimono CD3, andando poi a identificare la sottopopolazione di T citotossici esprimenti la glicoproteina CD8. La popolazione linfocitaria CD3pos risultava notevolmente aumentata nelle tre patologie analizzate soprattutto nei casi di UIP e Sarcoidosi sebbene l`analisi della loro distribuzione tra i vari distretti tissutali risultasse differente. Risultati simili si sono ottenuti per l`analisi dei linfociti CD8pos. La componente monocito-macrofagica è stata invece identificata tramite la glicoproteina CD68 che ha messo in evidenza una maggiore presenza di cellule positive nella Sarcoidosi e nella UIP rispetto ai casi di NSIP. I dati preliminari di questo studio indicano che il rimodellamento strutturale emo-linfatico e cellulare infiammatorio nella UIP si differenziano rispetto alle altre malattie interstiziali del polmone, avanzando l’ipotesi che il microambiente vascolare ed immunitario giochino un ruolo importante nella patogenesi della malattia

Mechanism of the hydropyrolysis of Manvers coal

Manvers coal has been pyrolysed to 500ºC in a stirred autoclave under various pressures of nitrogen (pyrolysis) and hydrogen (hydropyrolysis). All products were investigated. Pyrolysis of coals involves the transfer of hydrogen atoms from one part of their structure to another. In the above experiments there was no way of labelling the hydrogen or of distinguishing between hydrogen which was initially part of the coal and hydrogen originating in the external atmosphere. Consequently, Manvers coal has been pyrolysed in an atmosphere of deuterium in order to obtain greater insight into the mechanism of hydropyrolysis. In particular it was hoped to distinguish between direct hydrogenation (deuteration!) of the coal and the products of pyrolysis and the 'shuttling' of hydrogen atoms between different parts of the pyrolysing coal. The addition to the coal of 5% (wt.% of coal) of either tetralin or pyrite was also studied. A variety of techniques were used to analyse the products of pyrolysis: gas chromatography - mass spectrometry and high performance liquid chromatography for tars; thermal conductivity gas chromatography and high resolution mass spectrometry for gases; methanol densities, microporosities and diffuse reflectance infra red spectroscopy for the cokes (chars); refractive index to determine deuterium in the liquor. An attempt has been made to apply basic thermodynamics to reactions which are likely to occur in the hydropyrolysis of coals. Diffusion and effusion rates for hydrogen and tar molecules have also been estimated.

Sweat Lodges in Iron Age Iberian Peninsula: New Data, Typologies and Interpretations

Three questions on the study of NO Iberian Peninsula sweat lodges are posed. First, the new sauna of Monte Ornedo (Cantabria), the review of the one of Armea (Ourense), and the Cantabrian pedra formosa type are discussed. Second, the known types of sweat lodges are reconsidered underlining the differences between the Cantabrian and the Douro - Minho groups as these differences contribute to a better assessment of the saunas located out of those territories, such as those of Monte Ornedo or Ulaca. Third, a richer record demands a more specific terminology, a larger use of archaeometric analysis and the application of landscape archaeology or art history methodologies. In this way the range of interpretation of the sweat lodges is opened, as an example an essay is proposed that digs on some already known proposals and suggests that the saunas are material metaphors of wombs whose rationale derives from ideologies and ritual practices of Indo-European tradition.

Pneumothorax in the Emergency Room: personal caseload

The aim of this study was to collect information on the incidence, pathophysiology, treatment and mortality of pneumothorax in the Emergency Room. Pneumothorax is classified as spontaneous (primary, secondary or catamenial) or traumatic (iatrogenic or secondary to a blunt or penetrating chest injury). Between January 2007 and December 2009, 102 patients with pneumothorax were seen in our Emergency Room. Their records were examined and their data collected retrospectively. The type and side of the pneumothorax and age, sex, incidence and mortality were analyzed. The cases, involving 93 males and 9 females, broke down as follows: 68 spontaneous (66.7%), 33 traumatic (32.3%) and one iatrogenic (0.98%). The mean age was 47.3 (range 12-99); the incidence was 0.10%. There were no deaths due to pneumothorax in the Emergency Room. Traumatic pneumothorax was associated with blunt chest trauma, pleural effusion, hemothorax, cranial trauma, fractured collarbone, upper and lower limb fracture, pelvic fracture, vertebral and spinal trauma, sternum fracture and abdominal trauma. Pneumothorax is a common clinical problem. A multidisciplinary approach is essential to reduce the risk of morbidity and mortality. The incidence of pneumothorax in the Emergency Room was similar to that reported in the literature, while mortality data cannot be compared due to the lack of published studies.

Heart failure in young adults

Heart failure (HF) is a major health concern affecting 15 million people in Europe and around 900 000 people in the U.K. HF predominantly affects the elderly, with the mean age of patients with a diagnosis of HF between 70 and 80 years. Most previous HF studies have accordingly focused on older patients. Although HF is less common in younger adults (<65 years), 15% to 20% of patients hospitalised with HF are younger than 60 years of age. Very few studies have described the characteristics of younger adults with HF and its outcome. The aims of this thesis are to describe the clinical characteristics of younger adults with HF, explore the epidemiology of HF in younger adults and determine their short- and long-term outcomes. This was made possible by access multiple databases consisting of large patient cohorts with HF. The first chapter is a systematic literature review of younger adults with HF. Gaps in the current literature were identified and the thesis focused on some of these. The CHARM study allows detail characterisations of younger adults with HF. It recorded characteristics of patients with HF, including symptoms and signs of HF, electrocardiographic changes, chest radiographic findings, and also left ventricular ejection fraction. HF hospitalisations and its precipitating factors were also recorded systematically. Younger adults were more likely to have a third heart sound and hepatomegaly, but less likely to have pulmonary crackles and peripheral oedema. Similarly, radiological findings in younger adults were less likely to show interstitial pulmonary oedema or pleural effusion. Interestingly, younger adults aged <40 years not only have similar HF hospitalisation rate to older patients, however during their presentation with decompensated HF, they were less likely to have clinical pulmonary oedema and radiological signs of HF. Physicians managing younger adults with HF need to be aware of this. Younger adults were also less compliant with medications and lifestyle restriction resulting in hospitalisation with decompensated HF. Fortunately, despite these challenges, mortality rates in younger adults with HF were lower compared to older patients. To further substantiate the findings from the CHARM study, the MAGGIC study, a meta-analysis consists of over 40 000 patients with HF from large observational studies and randomised controlled trials, was examined. In both databases, the commonest aetiology of HF in younger adults was dilated cardiomyopathy. The ejection fraction was the lowest in younger adults. Similar to the CHARM study, mortality rates in younger adults were lower compared to older patients. However, in the MAGGIC study, by stratifying mortality into patients with preserved ejection fraction and with reduced ejection fraction, younger patients with preserved ejection fraction have a much lower mortality rate compared to patients with reduced ejection fraction. Findings from clinical trials are not always reflective of the real life clinical practice. The U.K. Clinical Practice Research Datalink (CPRD), a large and well-validated primary care database with 654 practices contributing information into the database representing approximated 8% of the U.K. population, is a rich dataset offering a unique opportunity to examine the characteristics, treatments, and outcomes of younger adults with HF in the community. In contrast to the CHARM and MAGGIC studies, younger adults aged <40 years were stratified into 20-29 and 30-39 years in the CPRD analysis. This is possible due to the larger number of younger adults with HF. Further stratifying the younger age groups demonstrated heterogeneity among younger adults with HF. In contrast to previous data showing younger adults have lower co-morbidities, the proportions of depression, chronic kidney disease, asthma, and any connective tissue disease were high among patients aged 20-29 years in the analysis from the CPRD. Surprisingly, the treatment rates for angiotensin converting enzyme (ACE) inhibitor, and aldosterone antagonist were the lowest in patients aged 20-29 years. With the exception of patients aged ≥80 years, treatment rate with beta-blocker was also the lowest in patients aged 20-29 years. With over two decades of follow up, long-term mortality rates in younger adults with HF can be determined. The mortality rates continued to decline from 1988 to 2011. Physicians managing younger adults with HF can now use this contemporary data to provide prognostic information to patients and their family. A hospital administrative database is the logical next platform to explore younger adults with HF. The Alberta Ministry of Health database links an outpatient database to a hospitalisation database providing ample data to examine the relationship between outpatient clinic visits and hospital admissions in younger adults with HF. Following a diagnosis of HF in the outpatient setting, younger adults were admitted to the hospital with decompensated HF much sooner than older patients. Younger adults also presented to emergency department more frequently following their first hospitalisation for HF. In conclusion, this thesis presented the characteristics and outcomes of younger adults with HF, and helped to extend our current understanding on this important topic. I hope the data presented here will benefit not only physicians looking after younger adults with HF, but also patients and their family.

Vasculitis, a Rare Presentation of a Post-Streptococcal Syndrome

Post-streptococcal vasculitis is not awell-recognized non-suppurative complication of Group A streptococcal infections. Seventeen-year-old male was admitted with palpable purpura in the limbs, ankle swelling, microscopic hematuria and elevated inflammation markers. After short remission period, an extensive exudative pleural effusion was identified. High anti-streptococcal antibodies titers were found. This report illustrates an atypical and rare presentation of a post-streptococcal syndrome.

TAFRO Syndrome in a Patient of South-American Descent

A 31-year-old Caucasian woman of South-American descent was diagnosed with a variant of multicentric Castleman disease (MCD) that has been reported in Japan as Castleman-Kojima disease. This is a systemic inflammatory disorder known as TAFRO Syndrome which includes thrombocytopenia, polyserositis (ascites/pleural effusion), microcytic anemia, myelofibrosis, fever, renal dysfunction and organomegaly, with immunologic disorder, polyclonal hypergammaglobulinemia, and elevated levels of interleukin-6 (IL-6) and the vascular endothelial growth factor present in serum and/or effusions. Optimal therapies are not well established. The patient was treated with methylprednisolone and rituximab. Following the start of treatment, the patient has been asymptomatic for over 8 months.

Acute Acalculous Cholecystitis as a Presenting Manifestation in Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is known to involve the gastrointestinal tract, but gallbladder involvement is rare. The authors report the case of a 26-year-old postpartum female who presented with acute right upper quadrant abdominal pain and was diagnosed with acute acalculous cholecystitis (AAC). In the presence of concomitant features of nephritis, pericardial effusion, anaemia and positive ANA titre, the diagnosis of SLE was confirmed during hospitalisation. Histopathological analysis of the gall bladder revealed evidence of vasculitis. Although rare, AAC can be the first presentation of patients diagnosed with SLE. Prompt diagnosis and management results in a better patient outcome.
