The differential diagnosis for LIP includes diffuse lymphoid hyperplasia (hyperplasia of bronchial mucosa-associated lymphoid tissue [MALT]), nodular lymphoid hyperplasia, lymphoma (of mucosal-associated lymphoid tissue or small lymphocytic types), and the patterns of OP, NSIP, hypersensitivity pneumonitis, and UIP ( 89). Diffuse lymphoid hyperplasia without alveolar septal infiltration has been included under the category of LIP in previous studies ( 151). Although there may be some overlap in these patterns, for the purposes of this classification the term LIP is limited to those cases with extensive alveolar septal infiltration ( 147).

Importantly, the finding of an NSIP pattern on biopsy should prompt the clinician to redouble efforts to find potentially causative exposures. NSIP may be the presenting manifestation preceding the diagnosis of collagen vascular disease by several months or several years. The NSIP pattern may also be the lone histologic feature in a patient with hypersensitivity pneumonitis. Therefore, care should be taken to search for serological and other markers of the connective tissue diseases and a careful search for potential exposures is essential. It is possible that specific occupational exposures may give rise to this pattern. New timetable for South Wales launched by Great Western Railway". RailAdvent. 5 October 2019 .

Unit 165128 was in service as a hybrid unit with 58609 (MOS vehicle from 166209) inserted in the middle from November 2015 until May 2016. This was due to one of its driving vehicles being damaged in an engine fire on the North Downs line in November 2015, [ clarification needed] rendering it out of service, and so to provide another 3-car train in service. [11] Note that you may use our state-of-the-art calculator above to obtain the quotient of any two integers or whole numbers, including 165 and 2, of course. Establishment of a firm clinicopathologic diagnosis allows the patient and clinician to make more informed decisions about therapy.

Signal passed at danger and subsequent near miss, Chalfont & Latimer station 21 June 2020" (PDF). Rail Accident Investigation Branch . Retrieved 26 July 2021.Although a highly probable diagnosis of IPF can be made without a lung biopsy, a definitive diagnosis of IPF and of the other forms of IIP can be established only with the aid of a surgical lung biopsy (Figure 2 ). In most cases the biopsy provides definitive classification of patients into the recognized histologic patterns of UIP, NSIP, OP, DAD, DIP, respiratory bronchiolitis (RB), and LIP. It also allows for confirmation or exclusion of an alternative diagnosis such as sarcoidosis, hypersensitivity pneumonitis, LAM, or lymphangitic carcinoma, or suggests the presence of an occupational disease such as hard metal disease. In lung biopsy specimens with moderate or marked acute and/or chronic inflammation, it is useful to perform special stains to exclude infectious organisms. Ladbroke Grove rail crash: On 5 October 1999, unit 165115 passed a signal at danger while leaving London Paddington on a Thames Trains service. This resulted in a serious collision with a London-bound HST service. 31 people were killed and 417 were injured.

Chiltern Railways 3-car Class 165/0 unit Great Western Railway 3-car Class 165/1 unit Named units [ edit ] Almost all of the current treatments for the IIPs have potentially serious risks and side effects, and it is not reasonable to expose patients to these risks in the presence of diagnostic uncertainty.The histologic differential diagnosis for cases of NSIP with a cellular pattern includes the patterns of hypersensitivity pneumonitis, organizing pneumonia, LIP, resolving DAD, eosinophilic pneumonia, and fibrosing NSIP (17, 21, 23. 89). Hypersensitivity pneumonitis shows a pattern consisting of bronchiolocentric cellular interstitial pneumonia, scattered, poorly formed granulomas, and intralumenal organizing fibrosis ( 102, 103). The presence of loose, poorly formed granulomas in a case with a cellular NSIP pattern should raise concern to exclude hypersensitivity pneumonitis, infection, collagen vascular disease, or drug-induced pneumonitis. To help exclude infection the biopsy should be examined with special stains for fungi, Pneumocystis carinii, and acid-fast bacilli. The lymphoid infiltrate of the cellular NSIP pattern is less severe than the extensive diffuse alveolar septal infiltration observed in lymphocytic interstitial pneumonia. The interobserver variability of pathological interpretation, particularly among general pathologists, needs to be defined. In more recent publications the term NSIP has evolved from its original use, which was intended to indicate a histologic pattern with a variety of etiologies ( 17). Now it is almost exclusively used to identify a form of IIP ( 18, 20, 21, 35, 36, 40, 90, 94-96). However, the concept of an idiopathic form of NSIP presents a problem for the clinician because there is no recognized and distinctive clinical description for patients presenting with this histologic pattern on lung biopsy. Although these patients have a better prognosis than those with IPF, the clinician does not know this in advance. This improved prognosis has been observed in several studies and appears to correlate with differences in the dominant pathology, whether a cellular or fibrotic pattern of NSIP is present and dominates ( 17, 18, 20, 21, 23, 36, 40, 94, 95). Further subclassification may become necessary, but this remains an issue for further study. It is possible that specific occupational exposures may give rise to this pattern. The majority of patients recover completely on administration of oral corticosteroids, but a significant number relapse within 1 to 3 mo when the corticosteroids are reduced (usually to below 15 mg/d) or stopped ( 37, 106). Prolonged treatment for 6 mo or longer is advised. A small proportion of patients recovers spontaneously ( 37). Rare cases previously classified as COP are reported to progress to respiratory failure and death. In some of these cases, additional features of diffuse interstitial fibrosis have been present, suggesting an alternative diagnosis including organizing pneumonia superimposed on a UIP lesion (acute exacerbation or accelerated decline of IPF) ( 107, 109-111). The transfer of the 165 (and 166) units to services in and around Bristol and Exeter have overall allowed units that previously operated these services to move further west, such as the Class 150 and Class 158 units. [17] More so than the 166 units, a lot of the 165 units remain to be based at Reading TMD where they continue to operate Thames Valley services.
