PERSISTENT ASYMPTOMATIC SEVERE HYPOGLYCAEMIA DUE TO TYPE 0A GLYCOGENOSIS - GENERAL AND ORO-DENTAL ASPECTS.

BACKGROUND: Type 0 glycogenosis is a genetic metabolic disorder characterized by the absence of glycogen synthesis of hepatic synthase and hence of liver glycogen stores in normal amounts. It is an extremely rare condition. CASE STUDY: This case is a 5-year and 11-month-old female child with asymptomatic severe hypoglycemia in the last two years. During the admission and afterwards, an extensive panel of paraclinical and imaging investigations was carried out to diagnose and document the case, which led to the specific genetic test. The result was positive for 2 heterozygous mutations in the GYS2 gene (hepatic glycogen synthase), the p.547C> T mutation was pathogenic (class 1) and c.465del, frameshift likely pathogenic (class 2). In order to integrate the clinical picture of patients with this condition and to establish potential correlations regarding the specific aspects with the general development and the phenotype, the oro-dental status was investigated. CONCLUSION: The investigations showed a positive correlation with literature data in several respects: low stature, hypoglycemia with hyperketonemia but normal plasma lactate, postprandial and contradictory hyperglycemia, delayed bone development, etc. Oro-buco-maxillary aspects showed a slight delay in the dental eruption. Dietary therapy and stricter dental care and additional prophylaxis are required.

New organophilic kaolin clays based on single-point grafted 3-aminopropyl dimethylethoxysilane.

In this study, the organophilization procedure of kaolin rocks with a monofunctional ethoxysilane- 3 aminopropyl dimethyl ethoxysilane (APMS) is depicted for the first time. The two-step organophilization procedure, including dimethyl sulfoxide intercalation and APMS grafting onto the inner hydroxyl surface of kaolinite (the mineral) layers was tested for three sources of kaolin rocks (KR, KC and KD) with various morphologies and kaolinite compositions. The load of APMS in the kaolinite interlayer space was higher than that of 3-aminopropyl triethoxysilane (APTS) due to the single-point grafting nature of the organophilization reaction. A higher long-distance order of kaolinite layers with low staking was obtained for the APMS, due to a more controllable organiphilization reaction. Last but not least, the solid state (29)Si-NMR tests confirmed the single-point grafting mechanism of APMS, corroborating monodentate fixation on the kaolinite hydroxyl facets, with no contribution to the bidentate or tridentate fixation as observed for APTS.

[Obstructive jaundice by genodermatosis--case report]. / Icter obstructiv prin genodermatoza--caz clinic.

BACKGROUND: Neurofibromatosis type I, or Recklinnghausen disease, is the most frequently occurring neurofibromatosis, in 1/3000-11,5000 of children born. This disease is a genodermatosis with 1/3000-1/5000 autosomal dominant transmission. Incriminated in the pathological appearance of the disease gene is located on chromosome 17, gene product, neurofibromina, is a protein involved in controlling cell differentiation and proliferation. Skin manifestations can be associated with the same papillary tumors and the internal organ. Treatment is surgery for larger tumors. Worse prognosis in malignant developpment, with the lower quality of life in the presence of complications, as in this case: mechanical obstructive jaundice. MATERIAL AND METHOD: Patients aged 75 years, admitted for obstructive jaundice (progressive, pruritic), cutaneous papillomas (0.5-3 cm) on the trunk and several hyperpigmented brown spots (5-6 cm diameter). Cutaneous lesions (45 years old) have been previously diagnosed by histological examination. RESULTS: We did surgery under general anesthesia: cholecystectomy, intraoperative choledocoscopy of bile duct. In the last portion of bile duct we found pedicled tumors. We did partial excision of tumors and coledoco-duodenoanastomosis in healthy tissue. Histological examination showed neurofibrodermatoza type I. Discharge 12 days postoperatively. CONCLUSIONS: Preoperative diagnosis suggested the possibility of mechanical jaundice by malignancy. Etiologic diagnosis of this rare form of obstructive jaundice could not be established before surgery, only by histological examination of the excised tumors.

Breast-conserving surgery in breast cancer.

The breast cancer treatment is based nowadays on new surgical options: breast-conserving surgery, which applies at least for the first and second stage cancer, with radical intention. We have been practicing breast-conserving surgery for the last 16 years and we have performed 303 breast conserving operations from a total of 673. We recorded 12 local recurrences (3,96%) and 2 deaths due to cancer progression. Our protocol includes removal of the primary tumor with enough surrounding tissue to ensure negative margins of the resectable specimen, associated with axillary lymph-node dissection and postoperative breast irradiation. Our oncologist indicated chemotherapy on different postoperative conditions: tumor size, axillary lymph node involvement, patient's age, etc. The purpose of this paper is to emphasize our modest experience, nevertheless to draw the attention on important results, obtained by long-term monitoring of the patients who underwent breast-conserving surgery, in a two prospective protocols, and demonstrate the importance and applicability of breast conserving therapy. The conclusion of this study is that breast-conserving surgery followed by breast irradiation is reliable, as the results are similar with radical mastectomies; the main objective is to obtain a good cosmetic result, which depends on tumor size / breast size.

IgM, but not IgA rheumatoid factor interferes with anti-cardiolipin and antiß2 glycoprotein I measurements: a quantitative analysis.

IgM rheumatoid factor (RF) is sometimes referred to as capable of causing interference in the IgM anti-cardiolipin (aCL) testing. Published guidelines are, however, inconsistent, and evidence regarding the interference is limited. Our goal was investigate IgM and IgA RF cross-reactivity and/or interference in IgM and IgA aCL and anti-ß2 glycoprotein I (aß2GPI) testing. Serum specimens with high IgM and IgA RF levels were tested for IgG, IgA and IgM aCL and aß2GPI antibodies to examine cross-reactivity. Samples containing IgG aCL and aß2GPI antibodies were spiked with IgM (and IgA) RF, and samples with high RF levels were spiked with IgG aCL antibodies. The mixtures were tested for IgM and IgA aCL and aß2GPI antibodies. Specimens with high IgM and IgA RF concentrations did not test positive for IgM or IgA aCL and aß2GPI antibodies (except one weak positive IgA aß2GPI result), indicating the lack of cross-reactivity. In the spiked specimens, addition of IgM RF caused significant positive bias in the measurement of both aCL and aß2GPI antibodies of IgM isotype in the presence of IgG aCL and aß2GPI antibodies. The threshold for triggering significant interference was 318( )IU/ml for IgM RF, and 77 GPLU/ml for IgG aCL. Neither IgM, nor IgA RF, however, affected the IgA antiphospholipid (aPL) antibody testing. IgM RF can cause a false-positive IgM aCL result in the presence of IgG aCL antibodies. In studies on the prevalence and clinical significance of IgM aPL antibodies, RF interference should be considered and RF testing should be performed.

[Diseases mimicking advanced-stage epithelial ovarian cancer]. / Afectiuni mimând cancerul ovarian epitelial în stadiu avansat.

This paper draws attention towards 3 cases with different pathologies all of which suggesting however both clinically and by imaging means as the most likely diagnosis advanced-stage epithelial ovarian cancer since all these three postmenopausal women had been admitted to the hospital with ascites, pelvic masses and deterioration of the physical wellbeing (fatigue, decreased appetite, weight loss, pallor). Findings during exploratory laparotomy on all these three pacients included ascites (hemorragic in one case) diffuse tumorous implants throughout the abdominal and pelvic peritoneal surfaces (in two cases) and the ovarian tumour. Postoperatively, the final histopathologic diagnoses consisted of primary peritoneal carcinoma (one pacient), peritoneal tuberculosis (TB, one pacient) and hepatic cirrosis with an incidental benign adnexial mass (one pacient). Moreover, nonmalignant ovarian tumours were certified in all three cases under current presentation. The differential diagnosis of the ovarian cancer and a tailored approach to treatment for each of these three pathologic entities will also be described in detail.

B cell depletion therapy in systemic lupus erythematosus: relationships among serum B lymphocyte stimulator levels, autoantibody profile and clinical response.

OBJECTIVE: To assess the relationships between serum B lymphocyte stimulator (BLyS) levels, autoantibody profile and clinical response in patients with systemic lupus erythematosus (SLE) following rituximab-based B cell depletion therapy (BCDT). METHODS: A total of 25 patients with active refractory SLE were followed for >or=1 year following BCDT. Disease activity was assessed using the British Isles Lupus Assessment Group (BILAG) system, and serum levels of BLyS and autoantibodies to dsDNA and extractable nuclear antigens (ENA) measured by ELISA. Serum immunoglobulins and anti-dsDNA antibodies were assessed for expression of the 9G4 idiotope (indicating VH4-34 germline gene origin). RESULTS: Following BCDT, all patients depleted in the peripheral blood and improved clinically for >or=3 months. Pre-BCDT BLyS levels were quantifiable (median 1.9 ng/ml) in 18/25 patients and rose in most patients at 3 months post-BCDT (median 4.15 ng/ml). Nine patients, all with quantifiable pre-BCDT serum BLyS, experienced a disease flare within 1 year. This group of patients was more likely to harbour anti-Ro/SSA antibodies (odds ratio 1.76; p = 0.06) with higher serum levels (p = 0.0027; Mann-Whitney U test). Serum levels of anti-ribonucleoprotein (RNP)/Sm were also higher in this group (p<0.05). Expression of VH4-34 by serum immunoglobulins and anti-dsDNA antibodies had no predictive value for the length of clinical response. CONCLUSIONS: Patients with SLE with an expanded autoantibody profile and raised BLyS levels at baseline had shorter clinical responses to BCDT. This may reflect a greater propensity to, and degree of, epitope spreading in such patients and suggests that treatment regimens beyond BCDT may be necessary to induce long-lasting clinical remissions in these individuals.

[Stress urinary incontinence. Diagnostic and therapeutic aspects]. / Incontinenta urinara de efort. Aspecte diagnostice si terapeutice.

OBJECTIVE: The paper analyses the incidence, diagnosis and treatment options available for stress urinary incontinence (SUI) in women with pelvic floor dysfunction admitted to Craiova's Surgery Clinic IV. METHODS: This is a retrospective 10-year study comprising a surgical cohort of 420 patients with significant enough to alter quality of life SUI associated to ureterocele and cystocele and in 353 cases with rectocele too. The highest incidence of SUI was encountered between 50 and 59 years of age (range 39 - 81 years). In 21 of this case series the diagnosis of SUI was established soon after the surgical repair of the urethro-cystocele. The diagnosis of SUI was based on careful history and physical examination with emphasis on the gynecologic survey of the abdomen and pelvis but in the absence (for objective reasons) of urodynamic testing which is especially useful for SUI pathophysiological evaluation and thus surgery success rate prediction. All our 420 severe SUI associated with vaginal wall hernias underwent surgical treatment by either open Burch retropubic urethropexy or anterior colporraphy. RESULTS: Among anterior colporraphy treated patients SUI persisted in 19.3% of the cases (33 patients). Complications of Burch urethropexy procedure (despite its high ability for cure) in our case series include: urinary retention, hemorrhage into the space of Retzius, intraoperative injury to the bladder and long-term postoperative incisional hernia. Moreover, 5 patients (2%) of the group who underwent Burch operation were readmitted with recurrent urinary incontinence between 2 and 6 months after the aforementioned surgical intervention despite its good anatomical results in all of these cases. CONCLUSIONS: SUI is a prevalent disorder of women that can be diagnosed easily with history and physical exam. If symptoms persist and severely affect quality of life, despite modern noninvasive treatments, several surgical procedures are now available.

Enumeration and identification of human leukemic lymphocytes by their natural binding of bacteria.

The recently described property of bacteria to bind to human lymphocytes was used to distinguish between normal and chronic leukemic lymphocyte (CLL) populations. Strains of the following bacteria were used in this study: Arizona hinshawii, Escherichia coli strains 1 and 2, Bacillus globigii, Brucella melitensis, Corynebacterium diphtheriae strains 1 and 2, Corynebacterium xerosis, Sarcina lutea, Staphylococcus aureus, and Staphylococcus epidermidis. For identification of immunoglobulin-bearing lymphocytes, a strain of E. coli that did not bind to human lymphocytes was coated with anti-human light-chain antibody. Labeling of lymphocytes with bacteria was promoted by centrifugation. In the eight CLL patients studied, in which greater than 90% of the lymphocytes were leukemic cells, 52 to 77% were labeled by anti-human light-chain antibody-E. coli, 80 to 93% were labeled by Br. melitensis, and 78 to 95% were labeled by E. coli 1 compared to 11 to 24, 11 to 22, and 30 to 44%, respectively, in normal individuals, Thus, Br. melitensis, E. coli 1, and the anti-human light-chain antibody-E. coli may have diagnostic value for CLL. The percentage of the lymphocyte population that bound each of the other bacteria varied from patient to patient. Preliminary results obtained by studying the pattern of binding of E. coli 2, B. globigii, Sa. lutea, or S. aureus by leukemic lymphocytes suggest that categories of CLL patients may be distinguished by this method.

Covalent binding to alpha-macroglobulins of a protein with free SH groups produced by activated B cells: blocking by D-penicillamine and gold compounds.

alpha 2-Macroglobulin (alpha 2M) complexed with proteinases or modified by the action of amines has been shown to affect immune responses in vitro, though as yet the mechanisms are poorly understood. Supernates from rabbit lymphoid cells cultured in medium with normal rabbit serum and 35S-methionine (or 14C-leucine) were found to contain intensely radiolabeled alpha-macroglobulins (alpha M) (alpha 1 and alpha 2) on electrophoresis. When human alpha 2 M, instead of rabbit serum, was added to cultures, it also appeared radiolabeled, suggesting that lymphocyte-produced proteins (LyP) formed complexes with serum alpha M. These alpha M-associated LyP were produced in greater quantity when lymphocytes were cultured in the presence of mitogens; they were not produced by cells cultured in the presence of cycloheximide; they were produced primarily by B cells rather than T cells or macrophages. Pretreatment of serum or alpha M with methylamine, enhanced rather than inhibited the formation of LyP-alpha M complexes, a finding which is contrary to that expected if the LyP were a proteinase. Since this methylamine treatment of alpha M also results in the generation of free SH groups from the internal thioester bonds of alpha M, the formation of disulfide bonds between LyP and alpha M was considered. Indeed, (a) the LyP-alpha M complex formation was inhibited by N-ethylmaleimide, aurothiomalate, sodium aurothioglucose or D-penicillamine; (b) blocking the SH groups with NEM, of either culture fluid supernates or serum, had an inhibitory effect on the formation of these complexes; (c) the LyP-alpha M complexes were dissociated by sodium dodecyl sulfate (SDS) only after their reduction with 2-mercaptoethanol (2-ME). Thus, a disulfide bond was formed between alpha M and LyP with free SH groups (SH-LyP). Molecular sieving by high performance liquid chromatography (HPLC) of the serum-free radiolabeled supernates indicated that SH-LyP eluted at a position corresponding to a polypeptide of mol. wt of about 22,000. However, SDS-PAGE of the 22,000 mol. wt HPLC fraction showed that the major protein was approximately mol. wt 11,000 under both reducing and non-reducing conditions. In addition, the SH-LyP reduced by 2-ME from its binding site on alpha 2M had a mol. wt of about 11,000 in SDS-PAGE, suggesting that it was a non-covalent homodimer of mol. wt 11,000 polypeptides. We suggest that alpha 2M as well as SH-LyP may affect the immune system by functioning as SH-reactive agents.

Covalent disulfide binding of human IL-1 beta to alpha 2-macroglobulin: inhibition by D-penicillamine.

Secreted human IL-1 beta is known to have two free SH groups due to unpaired cysteines (positions 8 and 71). Alpha 2-Macroglobulin (alpha 2-M) has internal thioester bonds between cysteine and glutamate residues. Free SH groups may be generated at these alpha 2M residues through the action of proteinases, amines such as methylamine, or at a slow rate, by H2O ("aging" of alpha 2M). Thus, the possibility that IL-1 beta forms a disulfide bond with alpha 2M was investigated. 125I-labeled human rIL-1 beta (15 kDa) was incubated with fresh normal human serum or with purified alpha 2M, treated or not with methylamine. The mixtures were submitted to nondenaturing and denaturing polyacrylamide gel electrophoresis (PAGE) followed by autoradiography. IL-1 beta bound to commercially purified "aged" alpha 2M and to alpha 2M in methylamine-treated serum but not to native serum alpha 2M. It did not bind detectably to any other serum proteins. The addition of D-penicillamine (D-pen) during the reaction of [125I]rIL-1 beta with serum or purified alpha 2M blocked the covalent binding of rIL-1 beta to alpha 2M. [125I]rIL-1 beta was removed from alpha 2M by 2-mercaptoethanol in SDS. Thus, disulfide bonds were formed between the free SH groups on [125I]rIL-1 beta and those resulting from the cleavage of the internal thioester bonds of alpha 2M. "Cold" rIL-1 beta and a Cys71----Ser71 rIL-1 beta mutant effectively competed with [125I]rIL.1 beta for binding sites on alpha 2M. When complexes of rIL-1 beta or the mutant rIL-1 beta and alpha 2M were subjected to nonreducing SDS-PAGE and subsequent Western blot analysis, the rIL-1 beta molecules were found to be present in the alpha 2M bands in a dose-dependent manner. rIL-1 beta attached to alpha 2M in the presence or absence of D-pen showed similar biological activity in the mouse thymocyte-assay. Thus, rIL-1 beta attached noncovalently to alpha 2M is biologically active. The lack of inhibition of rIL-1 beta activity by binding to methylamine-treated alpha 2M in the absence of D-pen suggests, but does not prove, that the covalently bound rIL-1 beta is also active. We concluded that human rIL-1 beta binds to alpha 2M through the Cys at position 8 and that D-pen inhibits this binding. We speculate that this inhibitory effect may contribute to the therapeutic benefits of D-pen in patients with rheumatoid arthritis.

[The experience at the 4th Surgery Department of the University Hospital C.F. Craiova in the surgical treatment of inguinal hernia]. / Experienta Clinicii Chirurgicale IV a Spitalului Universitar C. F. Craiova în folosirea plaselor sintetice în tratamentul chirurgical al herniilor inghinale.

This paper aim is to present the experience of Surgery Department IV of University Hospital C. R. Craiova in groin hernias treatment using prosthetic meshes, also describing an original technical procedure of mesh-plasty that we have been practicing successfully in our clinic. The study is based on a number of 1757 groin hernias operated in Surgery Department IV of University Hospital C. F. Craiova during a period of 11 years (1993-2003). There have been used prosthetic meshes in a number of 230 hernias operated for the most part in the last years since mesh repair has become habitually. We have been using so far only prosthetic mesh made in Romania (polyester mesh). We had a single recurrent hernia and the immediate complications were minimal. The study refers us to practice prosthetic mesh repair in an extensive way and offers a technical alternative in using of prosthetic meshes by a simple and efficient procedure with good postoperative results.

[Surgical methods of covering head soft tissues defects]. / Modalitati chirurgicale de acoperire a defectelor de parti moi la nivelul capului.

Posttraumatic and post-excisional head soft tissue defects represent a challenge for the plastic surgeon due to the functional and esthetic impact of this body area. Choosing the simplest way of covering a defect is many times the most efficient way, but it must deliver a good tissue cover and their aspect and function must simulate the characteristics of that area. This article is proposing to be a brief description of all these procedures, informing and being necessary for every general surgeon. The methods of covering head soft tissues defects specific to plastic surgery will be presented in a ladder way from simple to complex, that means from the simple skin graft to island flaps and the tissues transfers. Choosing a right procedure refers to the etiopathogeny, and the length and width of the defect. We shall present advantages and disadvantages of each procedure, indications and their limits, giving specific clinical cases. We shall present the results for each type of procedure also, giving specific arguments for our option. We'll insist on the functional reconstruction of the lids, nose and cheek, as single defects and on the surgical limits which come upon very large soft tissue defects. Due to the complexity of the head structures, either single or complex, and to the functional and esthetic impact of these soft tissue defects, we consider this paper to be a real benefit. It is very important to choose the right procedure, considering all the factors who are implicated (sex, age, general condition, etiopathogeny, the length and width of the defect, previous treatments, patient wish, etc).

[The mirage of the first lesion (gallstones) and laparoscopic cholecystectomy are able to defer the diagnosis of colon cancer]. / Mirajul primei leziuni (litiaza veziculara) si colecistectomia laparoscopica pot întârzia diagnosticul de cancer colic.

The study's aim was to analyze a series of colon cancer cases in which the mirage of the first (clinically most obvious) lesion (gallstones) along with its minimally invasive approach - that explored only the biliary disease - had contributed to the delay of large bowel malignancy' diagnosis and treatment. 1327 patients aged between 17 and 83 years and diagnosed with cholecystolithiasis were operated upon laparoscopically in the Department of General Surgery of Craiova CFR University Hospital from 2000 through 2004. Four out of these 1327 patients (0,3%) were readmitted with the diagnosis of colon carcinoma between 1 and 16 months after the laparoscopic cholecystectomy. Our retrospective study gives a full report on these 4 cases insisting upon the links between their clinical - laboratory evaluations and final diagnosis. Despite the low laparoscopic cholecystectomy overlooked colon cancer' incidence it seems reasonable to both improve the technique of peritoneal cavity exploration during this type of surgery and extend the preoperative evaluation whenever the slightest suspicion of associated pathology is raised especially in patients over 50 years of age.

Enhancement of human MLR by very low concentrations of lipopolysaccharide and blocking of this enhancement by polymyxin B.

Addition of 50 micrograms LPS/ml to as little as 5 pg of LPS/ml to the allogeneic human mixed leukocyte reaction (MLR) enhanced [3H]thymidine incorporation 2-4-fold. The same concentrations of LPS had no effect on thymidine incorporation in cultures without the allogeneic cells. The Limulus amebocyte lysate (LAL) test we used was sensitive only to 15 pg LPS/ml indicating that the MLR is more sensitive to LPS than the LAL test. A commercially available RPMI 1640 culture medium used by many investigators was found to contain concentrations of LPS that would significantly enhance the MLR. Polymyxin B blocked the MLR-enhancing effect of LPS while having no inhibitory or stimulating effect itself. We concluded that low concentrations of LPS are helpful in revealing MLR incompatibilities by enhancing the lymphocyte responses and that the addition of polymyxin B is essential in the study of factors affecting the MLR by eliminating any LPS contribution.

A simple radioimmunoassay for the enumeration of rosette-forming cells.

A simple radioimmunoassay for the enumeration of Ig bearing (Ig+) lymphocytes by rosette formation with anti-Ig, antibody coated erythrocytes (Ab-E) is described. The method is based upon labeling lymphocyte populations with 51Cr, rosetting them with Ab-E, separating the rosetted from unrosetted cells by centrifugation through a Ficoll-Hypaque layer, counting the radioactivity of the unrosetted cells, and counting the radioactivity of the unrosetted cells in a rosetting system with unreactive uncoated-E. This permits the calculation of the percentage of rosette-forming Ig+ cells. The assay eliminates the subjectivity and tediousness of counting and distinguishing between rosetted and unrosetted cells under the microscope. Being also sensitive and reliable, this radioimmunoassay may, after suitable modifications, replace the conventional counting of other types of rosettes.

The use of Salmonella schottmulleri for mapping and separation of human lymphocyte subpopulations.

Human lymphocyte subpopulations (B cells, B1, B2, T1, T2, T3, and T4 cells; our denomination) have been previously identified and isolated by bacterial adherence and functional differences between them have been demonstrated. Here we examined the binding properties of Salmonella schottmulleri to human lymphocytes in peripheral blood smears and found that it binds to more lymphocyte subpopulations, namely B, T1, T2 and T3 cells, than any bacteria previously tested. Thus, using only four bacteria: Salmonella schottmulleri, Brucella melitensis, Arizona hinshawii and Bacillus globigii we identified in blood smears B cells, two B and four T cell subpopulations. When we used gelatin-coupled monolayers of Sal. schottmulleri to isolate lymphocyte subpopulations, we showed that the nonadherent (T4) cells could be efficiently separated from the adherent cells. Furthermore, we tested the isolated subpopulations for natural killing (NK) activity and for antibody-dependent cell-mediated cytotoxicity (ADCC). Using both NK and ADCC assays, we observed a significantly higher cytotoxic activity in the nonadherent cell population than in the unseparated or adherent cell populations. Also the nonadherent cells contained most of the lymphocytes that have receptors for the Fc portion of IgG and those cells described as large granular lymphocytes. We concluded that Sal. schottmulleri is a valuable new reagent for the identification and separation of human lymphocyte subpopulations.

Chromosome abnormalities in chronic active hepatitis.

An investigation on human peripheral blood lymphocyte chromosomes in chronic active hepatitis was carried out. A higher percentage of chromatid and chromosome lesions was recorded in all patients studied as compared with control groups-normal individuals, healthy subjects who had suffered from acute viral hepatitis, patients with alcoholic liver disease, and patients with mechanical jaundice due to cancer. The possible origin of these abnormalities is discussed.

Surface immunoglobulin in immunoproliferative diseases.

Malignant B cells may originate from any of the stages of differentiation of B cells, primarily from IgM bearing B cells. The malignant B cells maintain a limited potential for differentiation. In addition to surface immunoglobulins, various markers may be present on the B cell surface; when surface Ig cannot be identified, these markers are used to identify B cells. However, for practical purposes, the detection of surface Ig is most important in the identification of B cells in immunoproliferative diseases, particularly when the malignant cell population displays only one immunoglobulin light chain. The procedures used so far to detect surface Ig have several drawbacks regarding their sensitivity or their specificity. The advantages of new procedures which involve the identification of B cells by their natural binding of B. melitensis or the detection of surface Ig by antibody-coated E. coli are presented. Detection of changes in the percentage of B lymphocytes and in the ratio of kappa- to gamma-bearing B cells in blood smears or in lymphocyte suspensions may be helpful in the early diagnosis of immunoproliferative diseases.

[False surgical acute abdomen with intermittent acute porphyria]. / Fals abdomen acut chirurgical în cadrul unei porfirii acute intermitente.

This article presents a case of acute intermittent porphyria admitted to the Surgery Department of C.F. Craiova Hospital between 18.08.2003-26.08.2003 then transferred to the Colentina Hospital in Bucharest for diagnosis confirmation and adequate treatment. The purpose of this paper is to bring attention on a rare metabolic inherited disease that, due to its non-specific and often noisy symptoms and limited possibilities of biochemical, enzymatic and genetic diagnosis, could generate potential serious confusions. The presentes case illustrates the fact that sometimes the acute attack may be mistaken for an acute surgical affection which requires an emergency operation with all the aggravating consequences and delay in the real diagnosis. About 1% of acute attacks of porphyria may be fatal. Only the drugs known as safe should be prescribed. Basic treatment consists in oral and intravenous glucose and hematin administration.
