Arthritis in a patient with homozygous familial hypercholesterolemia

Familial hypercholesterolemia is a disorder of lipoprotein metabolism characterized by elevated cholesterol, low-density lipoprotein cholesterol, xanthomas and early onset atherosclerosis. Tendinitis and arthritis have been reported in patients with familial hypercholesterolemia. A report is presented of a 9-year-old girl with an acute arthritic attack who was diagnosed as homozygote familial hypercholesterolemia with hypercholesterolemic arthritis.     

Reversible airway obstruction in rheumatic mitral valve disease

Lung function was studied in 24 patients with advanced mitral stenosis scheduled for mitral valve replacement (MVR), and revealed an obstructive ventilatory pattern [rewording of this sentence OK] . Forty per cent of the patients had a forced expiratory volume in 1 s (FEV₁)<60% of that predicted in the preoperative period. Twenty-five per cent of those operated upon showed a similar pattern up to 110 weeks postoperatively. A blind study of the effect of placebo and β₂ agonist (salbutamol) inhalation was performed preoperatively and 6 months postoperatively, to evaluate the reversibility of airflow obstruction in these patients, flow volume curve and body plethysmographic measurement of airway resistance (Rex) and intrathoracic gas volume (VTG). Patients in the pre and postoperative period showed a significant difference between the placebo and the β₂ agonist responses for FEV₁, FEV₁ as percentage of FVC (FEV₁% FVC), peak expiratory flow rate (PEFR), flow rate of 50% of expiratory vital capacity ([¨max₅₀), Rex and VTG (P<0.001). We conclude that salbutamol inhalation improves obstructive impairment in patients with MVR pre- and postoperatively.     

Tuberculous peritonitis in 11 children: Clinical features and diagnostic approach

BACKGROUND: Tuberculous peritonitis (TBP) is a rare manifestation of childhood tuberculosis characterized by long-lasting abdominal symptoms and exudate and lymphocytes in the ascitic fluid. The diagnosis of TBP is rarely established unless a high index of suspicion is maintained. METHODS: The diagnostic features of 11 cases who were hospitalized with TBP in the Pediatric Infectious Diseases Ward of Dicle University Hospital, Turkey, were evaluated retrospectively. RESULTS: Seven cases were male and the ages of all cases ranged between 1 and 11 years. The onset of symptoms was 1-12 months (mean +/- SD 3.1 +/- 2.7 months) prior to the admission time. Nine patients gave a history of familial tuberculosis. Three cases had Bacillus Calmette-Guérin (BCG) scars and the results of five tuberculin unit (TU) tests in cases without and with BCG were over 10 and 15 mm, respectively. The most common presenting clinical symptoms and signs at admission were abdominal distention and ascites (100%), fever (27%) and loss of weight (18%). One case had accompanying tuberculous meningitis and two cases had concomitant pulmonary tuberculosis. Only one of 11 samples of ascitic fluid yielded Mycobacterium tuberculosis by the polymerase chain reaction method and no other microbiologic evidence was obtained in culture specimens. Ultrasonographic and computed tomographic imagings revealed high-density ascites that contributed well to the diagnosis. The diagnosis in two patients was proven histopathologically via peritoneoscopy and laparoscopy. All cases were treated with isoniazide, rifampisin for 9 months and pyrazinamide for the first 2 months. CONCLUSIONS: Radiologic diagnostic techniques, positive skin tests and a history of exposure to tuberculosis may contribute to the diagnosis of TBP, helped by clinical symptoms and findings, particularly when invasive diagnostic methods via peritoneoscopy and laparoscopy are not available in developing countries.     

An alternative method for restoring opposition after median nerve injury: an anatomical feasibility study for the use of neurotisation

Opposition, one of the most important functions of the hand, is lost or impaired after median nerve injury. Complete recovery does not always occur after treatment, and various techniques of opponensplasty are used for restoring opposition. This study was performed in order to develop an alternative method for selective restoration of thenar muscle function. Ten arms from 5 cadavers were used. The median nerve with its thenar motor branch (Tb) and the anterior interosseous nerve with its motor branch to pronator quadratus (PQb) were prepared in the distal forearm. The mean widths and the number of myelinated fibres of these nerves were: PQb 1.3±0.10 mm, Tb 1.4±0.12 mm and PQb 912±88 mm, Tb 1020±93 mm. The minimum necessary distance from the distal flexor crease of the wrist for neurotisation of the Tb by the PQb was 60±5.41 mm. It was concluded that PQb-Tb neurotisation would be possible anatomically. The advantages are that motor function is reestablished with a motor nerve, the diameters and the number of myelinated fibres of both nerves are similar, the loss of function after denervation of the pronator quadratus is slight and opponensplasty still remains as a final option.     

Infant feeding and growth: A study on Turkish infants from birth to 6 months

BACKGROUND: To evaluate the impact of various feeding patterns on the physical growth and mental development of infants, particularly during the first 6 months of life, and to compare growth patterns of Turkish infants with those of infants living in various countries. METHODS: One hundred and seventy-two healthy newborn infants were included in the study and were divided into three feeding groups: (i) 62 infants were exclusively breast-fed (BF); (ii) 58 infants were mixed-fed (MF) with both breast milk and formula; and (iii) 52 infants were formula-fed (FF). Infants were assessed at birth and at 1, 2, 3, 4, 5 and 6 months of age. Anthropometry was repeated on each occasion. The weight and length of the infants was also recorded. Analysis of variance and modified t-test were used for statistical evaluation of the results. RESULTS: Values in the BF group were the closest to the tabular norms for weight. Infants in the FF group tended towards a lower weight during the first 3 months (P < 0.05). During the second 3 months, weight gain observed in the FF group was significantly higher than that of BF infants. In comparison with MF infants, a significant progressive weight gain was detected in BF infants (P < 0.05). The values obtained for length increments were consistent with those for weight (P < 0.05 for BF vs FF). No significant difference was found between the length increments detected for BF and MF infants from birth to 6 months. CONCLUSIONS: These results suggest that exclusive breast-feeding is the most appropriate feeding pattern for newborn infants in Turkey and is sufficient during the first 6 months, the most important fraction of life.     

Stones in anomalous kidneys: Results of treatment by shock wave lithotripsy in 150 patients

OBJECTIVE: To determine the efficacy of shock wave lithotripsy (SWL) in anomalous kidneys. METHODS: From October 1990 to October 2002, 150 patients (93 men and 57 women) with anomalous urinary tracts, including 45 horseshoe kidneys, 57 duplex kidneys, 30 malrotated kidneys, 14 pelvic and four crossed ectopic kidneys were treated with SWL for urolithiasis at the Gazi University Faculty of Medicine. Shock wave lithotripsy was performed with Siemens Lithostar plus (Siemans, Erlanger, Germany) device and all procedures were carried under fluoroscopic control. Results: The mean shock wave number and intensity received by the patients was 3770 (range, 1380-4100) shocks and 18.4 (range, 16.1-19) kV per session, respectively. The minimum success rate was obtained in patients with lower calyceal (50%) followed by middle calyceal (60%) calculi. The stone-free rate decreased and the number of sessions per patient increased with increasing stone diameter (dm). In patients with a stone dm > 30 mm, only 34% could be stone-free, compared to a rate of 92% for calculi dm < 10 mm. The overall stone free rate at the third month was 68%. The best stone-free rates were obtained in patients with ureteral duplication (80.7%). The stone-free rates in horseshoe, malrotated, pelvic and crossed ectopic kidneys were found to be 66.7%, 56.7%, 57.2% and 25%, respectively. CONCLUSION: Shock wave lithotripsy might be an effective and minimally invasive treatment alternative in stone-bearing anomalous kidneys. The type of anomaly, stone burden and localization seem to be the main parameters effecting the treatment success.     

Papillary adenoma of the prostatic urethra: Report of two cases

Papillary adenoma of the prostatic urethra is a rare cause of hematuria, hemospermia and lower urinary tract obstruction, especially in young adults. We report two cases of papillary adenoma and their endoscopic views. One of the patients had a lesion located on the verumontanum and presented with hematuria, hemospermia and symptoms of lower urinary tract obstruction. The other patient had papillary lesions located in the paramontanal gutter and presented with persistent painless hematuria. The origin of both lesions was proven to be prostatic epithelial differentiation using immunohistochemical identification of prostate-specific antigen. Papillary adenoma is believed to be benign, therefore, both lesions were carefully excised and fulgurated transurethrally.

Improvement method for cervical cancer detection: A comparative analysis

Cervical cancer is a prevalent and deadly cancer that affects women all over the world. It affects about 0.5 million women anually and results in over 0.3 million fatalities. Diagnosis of this cancer was previously done manually, which could result in false positives or negatives. The researchers are still contemplating how to detect cervical cancer automatically and how to evaluate Pap smear images. Hence, this paper has reviewed several detection methods from the previous researches that has been done before. This paper reviews pre-processing, detection method framework for nucleus detection, and analysis performance of the method selected. There are four methods based on a reviewed technique from previous studies that have been running through the experimental procedure using Matlab, and the dataset used is established Herlev Dataset. The results show that the highest performance assessment metric values obtain from Method 1: Thresholding and Trace region boundaries in a binary image with the values of precision 1.0, sensitivity 98.77%, specificity 98.76%, accuracy 98.77% and PSNR 25.74% for a single type of cell. Meanwhile, the average values of precision were 0.99, sensitivity 90.71%, specificity 96.55%, accuracy 92.91% and PSNR 16.22%. The experimental results are then compared to the existing methods from previous studies. They show that the improvement method is able to detect the nucleus of the cell with higher performance assessment values. On the other hand, the majority of current approaches can be used with either a single or a large number of cervical cancer smear images. This study might persuade other researchers to recognize the value of some of the existing detection techniques and offer a strong approach for developing and implementing new solutions.     

The Haematology Analyser SF-3000: performance of the automated white blood cell differential count in comparison to the Haematology Analyser NE-1500

The present study evaluates the performance of automated white blood cell (WBC) differential counts by the new Haematology Analyser SF-3000. Five hundred and sixty-six WBC differential counts performed by the SF-3000 were compared with WBC differential counts of the well established analyser NE-1500 and to manual reference counts. Numerical results of the WBC differential counts were correlated to each other by regression analyses. The efficiency of instrument flagging for the presence of abnormal WBC was expressed as per cent of subjects correctly classified. Neutrophil and lymphocyte counts correlated well between analysers and to manual reference counts. Monocyte counts for the SF-3000 correlated significantly better with the microscopic counts, whereas correlations of eosinophils and basophils were better for the NE-1500. The efficiency rates of flagging for the presence of ≥1% abnormal WBC were 80% for the NE-1500 and 70% for the SF-3000. This difference was exclusively due to low specificity of the SF-3000 in flagging cells of the `Left Shift' category, especially in samples with elevated WBC counts. The flagging efficiencies for blasts, promyelocytes, myelocytes, atypical lymphocytes and nucleated red cells were identical for both analysers. Thus, with regard to the performance of automated WBC differential counts the SF-3000 seems comparable with other, well established haematology analysers.
