    Notes: FNAC is a simple diagnostic tool for the initial evaluation of various deep seated pathological lesions. This study describes the applicability and practical aspects of the technique in establishing the diagnosis of spinal tuberculosis (TB) with the aid of radiographic guidance. The study was conducted in a major teaching hospital in Kuwait between the years 1985 and 1994. Twenty-nine patients (M:F = 18:11 and age range 8–72 years) with clinically and/or radiologically suspected spinal TB were seen in the Department of Cytology, Mubarak Al Kabeer Hospital. The patients were re-examined by either computed tomography (CT) scanning (n = 19) or fluoroscopy (n = 10) to localize the lesion for FNAC. FNAC smears were routinely stained with Papanicolaou and Diff Quik stains and one smear of each case was stained with Ziehl–Neelsen (Z-N) stain for acid-fast bacilli (AFB). Aspirated purulent material or syringe washings of dry aspirates were also submitted for microbiological cultures including AFB. Radiological and cytological findings were recorded in each case. Radiological findings included: bony rarefaction and destruction (93.1%), narrowed disc space (89.7%), soft tissue calcification (65.5%) and para-vertebral abscess formation (51.7%). Cytological findings included: epithelioid cell granulomas (89.7%), granular necrotic background (82.8%) and lymphocytic infiltration (75.9%). Smears were positive for AFB in 51.7% of cases. A positive AFB culture was obtained in 82.8% of cases, including all cases with positive AFB on smear by Z-N stain. Radiologically guided FNAC with AFB culture is a simple, reliable and practical approach to diagnosing spinal TB lesions. With a high diagnostic yield, it allows immediate initiation of specific treatment, helps to avoid invasive diagnostic procedures, and decreases hospitalization time.

    Notes: Objective:  Endometriosis due to ectopic endometrial tissue that responds to hormonal stimulation and is extremely rare in a surgical scar appearing in 0.1% of women who have undergone Caesarean section. Fine needle aspiration cytology (FNAC) can be a valuable diagnostic aid in the evaluation of these subcutaneous abdominal masses.Methods:  We present the cytomorphological spectrum in eight cases of abdominal wall endometriosis diagnosed by FNAC over a 6-year period (June 1998–June 2004) in Mubarak Al-Kabeer Hospital (Kuwait). The patients ranged from 27 to 56 years of age. Seven had a prior Caesarean section and one had a hysterectomy for fibroid. They presented 3–8 years later with nodules in/near the abdominal scar. Five cases presented with a painful nodule, fluctuant with the menstrual cycle.Results:  Cytological findings comprised epithelial clusters and fusiform stromal cells with numerous haemosiderin-laden macrophages. Mild to moderate epithelial atypia was observed in three cases. A diagnosis of endometriosis was rendered in all the eight cases and tissue was available in four cases.Conclusions:  Endometriotic nodules need to be differentiated from other benign/malignant masses and evaluated for possible malignant transformation. FNAC provides a safe and effective tool for diagnosis thereby obviating the need for other procedures.

    Notes: Introduction:  Intracytoplasmic lumens (ICL) with or without magenta material and transgressing vessels are features of Hürthle cell neoplasms (HCN). After detection of intracytoplasmic colloid inclusions (CIs) including targetoid (magenta) body-like structures in the Hürthle cells (HC) in a case of Hashimoto's thyroiditis (HT), we reviewed cases of HT, thyroid neoplasms, hyperplastic nodules (HN) and colloid goitres to determine the frequency of these structures. Further, an attempt was made to find out the significance of CIs.Methods:  FNA smears of 120 HT, 101 colloid goitres, 11 HN, and 76 neoplastic goitres were examined. The presence of CIs and empty ICL were noted in epithelial cells in these lesions. An attempt was made to find out the difference between HT with and without CIs in respect of various cytomorphologic features. The groups were compared using the Fisher's exact test of probability.Results:  The CIs were present in 36 (30.0%) of HT, 26 (34.2%) of neoplastic goitres, 3 (27.3%) of HN, and 4 (4.0%) colloid goitres. As compared to colloid goitres, CIs were present in a significant higher number of cases in HN (P = 0.0202), neoplastic goitres (P 〈 0.0001), and HT (P 〈 0.0001). Among neoplasms the frequency of CIs in HCN (75.0%) was significantly higher than that of papillary thyroid carcinoma (PTC) (33.3%, P = 0.0466), and follicular neoplasm (14.3%, P = 0.0083). The CIs were more frequent in HC in HT and HCN but in follicular cells (FC) in other lesions. The HT cases with CIs differed significantly from those without CIs in respect of HC and their cellularity, cellularity of reactive lymphoid cells, extracellular colloid and empty ICL.Conclusion:  Care should be taken not to diagnose HT cases with an excessive Hürthle cell component and CIs, and PTC cases with Hürthlization and CIs, as HCN in FNA smears. Based on review of the literature and our findings, it is suggested that the Hürthle cell metaplasia in HT is a survival response of FC and the presence of CIs in Hürthle cell may represent their limited ability to synthesize colloid.

    Notes: Objective:  The histological diversity encountered in pleomorphic adenoma may cause diagnostic difficulty in fine needle aspiration (FNA) cytology due to limited and selective sampling. The present study based on 25 histologically confirmed pleomorphic adenoma cases attempts to find out to what extent FNA cytology reflects the histopathological features.Methods:  May-Grünwald-Giemsa and Papanicolaou stained smears, and haematoxylin and eosin stained paraffin sections of 25 pleomorphic adenomas of parotid and submandibular glands were reviewed. The cellularity, which was assessed in a sliding scale of 1+ to 4+, and proportions of epithelial to mesenchymal components in FNA smears and histology was determined and compared. The frequency of morphological features such as squamous metaplastic cells, cells with oncocytic change, acinus formation, mucus globules, papilla formation, giant cells, myxoid and chondroid matrix as well as specific nuclear features was compared between the two diagnostic methods, and the statistical significance was determined using Fisher's exact test of probability.Results:  There was complete concordance between cytology and histology with respect to overall cellularity in 14 (56.0%) cases and in the proportions of epithelial to mesenchymal components in 13 (52.0%). Epithelial cells and myxoid matrix were present in all cases. There was no significant difference between smear and tissue section with respect to frequency of squamous metaplasia, oncocytic change, acinus formation, papilla formation, mucus globules, giant cells, nuclear pleomorphism, nuclear chromatin pattern, and mitotic figures. Morphological parameters that were significantly higher in FNAC compared with histology included intranuclear cytoplasmic inclusions (36.0% versus 8.0%, p = 0.0374), nuclear grooves (84.0% versus 48.0%, p = 0.0090), and reniform nuclei (20.0% versus 0.0%, p = 0.0502). Chondroid matrix was the only parameter which was significantly more common in histology than in cytology (44.0% versus 4.0%, p = 0.019).Conclusion:  FNA cytology demonstrates well most of the histological features of pleomorphic adenoma of salivary gland and may be considered a useful tool in initial assessment of the tumour.

    Notes: Abstract The results of viscometric and optical microscopic studies indicated that both Syntan 25 and Syntan PUR in aqueous concentrated solutions (above their c.m.c. values) at 25 °C are spherical in shape. The size and other physico-chemical parameters e. g. Volumes of the aggregated particleM v, Radius of gyrationR g, Hydrodynamic radius ¯R h, Diffusion coefficient ¯D, and the Correlation times for aggregate rotationT r Translational diffusionT D and effective aggregation timeT a have been derived on the basis of microscopic results. The viscosity data for both Syntan 25 and Syntan PUR were analysed in terms of Einstein equation, Moulik equation, Jones-Dole equation. It has been shown that Syntan PUR was more highly hydrated than that of Syntan 25 although the intrinsic viscosity [η], of Syntan PUR is nearly 1.5 times greater than that of Syntan 25. The Flory-Huggins equation and Thomas equation has been compared in both the Syntans and it has been concluded that the Thomas' constantk 1 may be 12.50 for perfect spherical shape of the particle instead of 10.05 (which has originally been proposed by Thomas).

    Notes: Abstract Early ischemic colitis was induced in rats to evaluate the roles of FRs and intraluminal content. After 30 minutes of ischemia, biopsies for histology, conjugated dienes (CD) and malonaldehyde (M), presumptive marker of lipid peroxidation, were obtained at 0, 30, and 60 minutes reperfusion. Histology was unchanged. CD and M were elevated in ischemic and saline controls, and rose progressively during reperfusion; CD and M were essentially the same as non-ischemic controls during reperfusion with intraluminal corticosteroid (c) and Alcide (A). These agents may be beneficial in early ischemic colitis.
