Capillary zone electrophoresis (CZE) offers the potential for automating serum protein electrophoretic analysis traditionally performed on standard thin-layer agarose gels. The following describes the use of CZE compared to agarose gel electrophoresis (AGE) for the detection of dysproteinemia and paraproteinemia in a clinical study involving 240 patients. The study includes within-run and between-run reproducibility data on the Paragon CZE 2000 Clinical Capillary Electrophoresis System, in addition to concordance data between the two methodologies. Paraprotein quantitation studies comparing AGE versus CZE were also performed. Reproducibility for the automated CZE system was superior to the AGE system. Improved reproducibility for the CZE method is largely due to measuring protein absorbance directly at 214 nm versus the traditional AGE method that measures the amount of dye adsorbed to protein. Reproducibility data as percent coefficient of variance (% CV) for the five classic bands in a normal control serum for between-run precision ranged from 1.2 to 4.5% for CZE compared to AGE, which ranged from 3.8 to 8.0% CV. Concordance studies between AGE and CZE involving dysproteinemias including hypogammaglobulinemia, polyclonal and monoclonal gammopathies, acute and chronic inflammation, nephrosis, hepatodegenerative disease,
cirrhosis
, and
iron deficiency anemia
showed 96% agreement. Paraprotein classification, which compared the CZE immunosubtraction method to immunofixation electrophoresis (IFE) on agarose, showed 100% agreement. Certain dysproteinemias involving beta lipoprotein were in partial concordance due to the inability of the CZE procedure to detect this component. Detection limits for monoclonal gammopathies, providing they were not comigrating with other proteins, were IgG 50 mg/dL, IgM 75 mg/dL, and IgA 75 mg/dL. Paraprotein quantitative studies between the two methods showed less than a +/- 0.2 g/dL variation.

The watermelon stomach syndrome is an increasingly recognized cause of persistent acute or occult gastrointestinal bleeding, typically in elderly women. This disorder often presents with severe
iron deficiency anemia
, and a variety of associated conditions including autoimmune disease,
cirrhosis
, achlorhydria, and hypochlorhydria. Diagnosis is made by the characteristic endoscopic appearance of visible linear watermelon-like vascular stripes in the antrum. Histology confirms the vascular nature of this disorder, showing dilated and thrombosed capillaries in the lamina propria, associated with reactive fibromuscular hyperplasia. The optimum treatment of choice is not known. Several treatment options, including surgical antrectomy, and endoscopic photocoagulation with Nd:Yag laser, heater probe therapy, and bipolar electrocautery, have yielded excellent results. Pharmacological agents have also been used to treat selected numbers of patients, most of which comprise a small number of case reports.

We present the case of a 72-year-old woman with successful control of repeated episodes of bleeding from diffuse antral vascular ectasia (DAVE) by laser coagulation therapy. In addition to DAVE, the patient also suffered from severe
iron deficiency anaemia
(due to recurrent bleeding),
liver cirrhosis
, and huge tumours of hepatocellular carcinoma (HCC). She was referred from another hospital after failure to stop her bleeding episodes. Endoscopic examination revealed diffuse speckled telangiectasia over most of the stomach (from antrum to the upper portion of the body) and large numbers of blood clots. The patient had received repeated blood transfusions, haemostatic drugs, and H2 receptor antagonists at the other hospital, without improvement of the repeated bleeding. She underwent three sessions of endoscopic laser coagulation therapy for the lesions at our hospital after the final diagnosis of DAVE had been made based on the characteristic histological findings of biopsied specimens. This treatment improved her general condition and stopped the bleeding from the gastrointestinal tract even without fasting. Unfortunately, however, her liver function gradually worsened due to HCC and previous massive bleeding, and she finally died of liver failure three months after the last laser session. Autopsied specimens obtained from the patient's stomach revealed that macroscopic diffuse speckled telangiectasia and microscopic typical vasodilatation in mucosal and submucosal layers of gastric tissue had disappeared in the treated areas but not all portions of the DAVE lesion. These histological findings for the treated areas, in addition to the clinical improvement of bleeding, suggest that endoscopic laser coagulation therapy may be useful and one of the first choices in treatment for DAVE.

Systemic disease can produce changes in the nails. Perhaps the best known example of this is koilonychia as a sequale of
iron deficiency anemia
. "Half and half nail" is a type of pseudoleuconychia that can be caused by chronic renal disease, Kawasaki's disease,
cirrhosis
, and zinc deficiency. It has not been described in patients with Crohn's disease yet. Four male patients with Crohn's disease were observed. None of them had extraintestinal manifestations of Crohn's disease. The average duration of the disease was 5.25 (range, 1-10) years. The nail alterations were defined with a portion of the nail being as much as 15 to 40 percent of normal color distally, whereas the rest of the nail was white. The contrast between the two zones remains sharply demarcated even after constricting venous return. Histologic examination was not performed. Every patient had zinc deficiency but not hypalbuminaemia or sideropenia. After review of relevant literature (MEDLINE, PubMed, etc.), we found that half-and-half nail had not been described in Crohn's disease. This study was designed to highlight the fact that the half-and-half nail, which was thought to be a sign of chronic renal failure, also occurs in patients with Crohn's disease. The relationship of this symptom to clinical activity cannot yet be assessed and has only been observed in four cases.

The role of Helicobacter pylori (HP) in some digestive diseases (gastritis, ulcer, gastric cancer, MALT lymphoma) is well known. It has been suggested relatively recently that infection with HP can be involved in various extra-digestive conditions: respiratory disorders (chronic obstructive pulmonary disease, bronchiectasis, lung cancer, pulmonary tuberculosis, bronchial asthma); vascular disorders (ischaemic heart disease, stroke, primary Raynaud phenomena, primary headache); autoimmune disorders (Sjogren syndrome, Henoch-Schonlein purpura, autoimmune thrombocytopenia, autoimmune thyroiditis, Parkinson's disease, idiopathic chronic urticaria, rosacea, alopecia areata); other disorders (
iron deficiency anaemia
, growth retardations,
liver cirrhosis
). Case studies, small patient series and non-randomized trials that have shown a beneficial effect of HP eradication in different conditions are not convincing. According to Mastricht III the only conditions where HP eradication is indicated are immune thrombocytopenic purpura and
iron deficiency anaemia
.

In any study there remains a proportion of cases, about 25-40%, where cause of splenomegaly is not identified on usual evaluation, that is labelled as indeterminate group. The aim of this study was to evaluate various causes of splenomegaly. Thereafter the patients with splenomegaly of indeterminate origin were to be re-evaluated with detailed investigations (for the cause of splenomegaly). Causes of splenomegaly were looked into 100 adult patients with splenomegaly, admitted over a period of ten months in a teaching hospital in South India. Patients having ascites were excluded from the study. Malaria was the commonest cause of splenomegaly, observed in 22 patients. Other causes, in order of importance, were chronic myeloid leukaemia (n=11), non-cirrhotic portal fibrosis (n=9), enteric fever (n=9),
cirrhosis
of liver (n=8) and hyper-reactive malarial splenomegaly also called as tropical splenomegaly syndrome (n=7) and so on. Hyper-reactive malarial splenomegaly was the commonest cause (7 of 24 patients) of massive splenomegaly. Twenty-three patients had splenomegaly of indeterminate origin ie, cause could not be detected on first assessment. Detailed re-evaluation with repeat investigations including liver biopsy revealed the causes as follows: Hyper-reactive malarial splenomegaly -7 (30.4%), non-cirrhotic portal fibrosis - 4 (17.4%),
cirrhosis
of liver - 4 (17.4%) and
iron deficiency anaemia
- 5 (21.7%). In 3 patients (13.0%), no diagnosis could be arrived at despite best efforts. Obscure splenomegalies may be due to conditions like hyper-reactive malarial splenomegaly, non-cirrhotic portal fibrosis,
iron deficiency anaemia
, and even
cirrhosis
of liver, while malaria is still the most important cause of splenomegaly in India. Whereas the overall incidence of hyper-reactive malarial splenomegaly was only 7% in this study, it stood as the leading cause (29.2%), when analysed among patients with massive splenomegaly. Liver biopsy should be performed in all cases of obscure splenomegaly to arrive at the final diagnosis.

Here we report a case of a 25-year-old woman with mesenteric and hepatic sarcoidosis without lung involvement complicated by severe noncirrhotic portal hypertension. In 1992, at the clinical presentation, she had abdominal pain, asthenia, and weight loss. Splenomegaly, signs of flogosis,
sideropenic anemia
, and cholestasis were observed. Laparoscopic abdominal exploration and histological analysis demonstrated noncaseating granulomas of the liver, abdominal lymph nodes, and mesenteric connective tissue. The clinical course was severe with episodic remissions and recrudescences characterized by ascites (mild or moderate), elevation of bilirubin levels (mean: 1.1 mg/dl; range: 0.9-3.5 mg/dl), reduction of albumin levels (mean: 4 g/dl; range: 3.4-4.2 g/dl), and prolongation of elevated international normalized ratio (mean: 1; range: 0.9-1.4). In 1997, the patient had variceal bleeding. Complete hemostasis was obtained with band ligation. Liver function was preserved, and until 2000 the disease remained stable. In 2001, the patient became pregnant. At the 36th week of gestation, the patient delivered a healthy female infant and afterwards remained in clinical remission. This report stresses that sarcoidosis can have a hepatic and mesenteric involvement in absence of thoracic lymphadenopathy. Portal hypertension may be severe, and in absence of
cirrhosis
it may be associated with portal thrombosis. Finally, portal hypertension in patients with hepatic sarcoidosis and preserved liver function should not be considered as an absolute contraindication to pregnancy.

It is known that glycation among various proteins is increased in diabetic patients compared with non-diabetic subjects. Currently, among these glycated proteins, glycated hemoglobin (HbA(1C)) is used as the gold standard index of glycemic control in clinical practice for diabetes treatment. However, HbA(1C) does not accurately reflect the actual status of glycemic control in some conditions where plasma glucose changes during short term, and in patients who have diseases such as anemia and variant hemoglobin. In comparison, another index of glycemic control, glycated albumin (GA), more accurately reflects changes in plasma glucose during short term and also postprandial plasma glucose. Although GA is not influenced by disorders of hemoglobin metabolism, it is affected by disorders of albumin metabolism. This review summarizes diseases and pathological conditions where GA measurement is useful. These include the status of glycemic control changes during short term, diseases which cause postprandial hyperglycemia,
iron deficiency anemia
, pregnancy, chronic liver disease (
liver cirrhosis
), chronic renal failure (diabetic nephropathy), and variant hemoglobin.

Since the original description of colonic varices in 1954 [N Engl J Med 1954;250:434-438], fewer than 100 cases have been reported in the literature. Particularly, even fewer cases of cecal varices have been reported. More than 75% of these cases have been due to portal hypertension. Our objective is to contribute a rare case with an uncommon presentation to the medical literature. We present the case of a 53-year-old male with hepatitis C and hepatitis B
liver cirrhosis
who presented for outpatient colonoscopy. The indication for colonoscopy was bright red blood per rectum and
iron deficiency anemia
. A significant amount of varices were noted in the cecum and proximal ascending colon. No endoscopic evidence of colonic bleeding was noted. This is the first reported case of cecal varices not presenting with massive lower gastrointestinal bleeding.

Knowledge of the anatomy and function of the nail apparatus is essential when performing the physical examination. Inspection may reveal localized nail abnormalities that should be treated, or may provide clues to an underlying systemic disease that requires further workup. Excessive keratinaceous material under the nail bed in a distal and lateral distribution should prompt an evaluation for onychomycosis. Onychomycosis may be diagnosed through potassium hydroxide examination of scrapings. If potassium hydroxide testing is negative for the condition, a nail culture or nail plate biopsy should be performed. A proliferating, erythematous, disruptive mass in the nail bed should be carefully evaluated for underlying squamous cell carcinoma. Longitudinal melanonychia (vertical nail bands) must be differentiated from subungual melanomas, which account for 50 percent of melanomas in persons with dark skin. Dystrophic longitudinal ridges and subungual hematomas are local conditions caused by trauma. Edema and erythema of the proximal and lateral nail folds are hallmark features of acute and chronic paronychia. Clubbing may suggest an underlying disease such as
cirrhosis
, chronic obstructive pulmonary disease, or celiac sprue. Koilonychia (spoon nail) is commonly associated with
iron deficiency anemia
. Splinter hemorrhages may herald endocarditis, although other causes should be considered. Beau lines can mark the onset of a severe underlying illness, whereas Muehrcke lines are associated with hypoalbuminemia. A pincer nail deformity is inherited or acquired and can be associated with beta-blocker use, psoriasis, onychomycosis, tumors of the nail apparatus, systemic lupus erythematosus, Kawasaki disease, and malignancy.
