Introduction: In the emergency room, acute pain in the abdomen is one of the most common symptoms that patients present with, and it is a result of a myriad of causes, leading to an exhaustive differential diagnosis. A perforated peptic ulcer is a rare cause of acute right iliac fossa or lower quadrant abdominal pain. It causes leakage of gastrointestinal contents in the area, resulting in localized inflammation and pain that is clinically similar to acute appendicitis. This condition is known as Valentino's syndrome.Aim: This study aims to highlight clinical and radiological features for patients with Valentino's syndrome, improving diagnostic accuracy.Methods: The authors conducted a retrospective analysis of all diagnosed cases of Valentino's syndrome from multiple facilities within the same organization for the research study. A total of 14 nonsequential cases were gathered. The term "Valentino's syndrome" was used to search in the PubMed and Google Scholar databases for the review of literature, and only 17 cases were found and reviewed.Results: Of the 31 patients, 83.9% were male, with a mean age of 39 years. Of all patients who presented with abdominal pain, 25.8% had it in the lower right abdomen. Vomiting (38.7%), nausea (35.4%), fever (16.1%), and constipation were all associated symptoms (12.9%). All cases were clinically diagnosed as acute appendicitis. Many patients had elevated levels of white blood cells, neutrophils, and CRP. Computed tomography (CT) scan was used in 70.9% of the cases, followed by ultrasound (58%) and x-ray (45.1%), where pneumoperitoneum and duodenal perforations were common. Graham's patch was used in 48.3% of the cases, appendectomy was used in 16.1% of the cases, and conservative care was used in 19.3% of the cases. Most patients were given proton pump inhibitors and antibiotics for Helicobacter pylori.Conclusion: Timely diagnosis of Valentino's syndrome via CT imaging is critical because it leads to immediate perforation repair. Patients' mortality and morbidity may be reduced if they are aware of the condition and receive an accurate, rapid preoperative diagnosis.

A sensitive and selective method has been developed for the determination of palladium(II) and nickel(II). A new reagent and two complexes have been prepared in aqueous solutions. The method is based on the chelation of metal ions with 4-(4'- antipyriyl azo ) -2-bromo phenol (APBP) to form an intense color soluble products, that are stable and have a maximum absorption at 498 nm and at 433.5 nm and εmaxof 0.21×104and.0.38×104Lmole-1cm-1for Pd(II) Ni(II) respectively. A linear correlation of (0.2 - 3) and (0.6 -2.2) ppm for Pd(II) Ni(II) respectively. The stoichiometry of both complexes was found to be 1:2 (metal:ligand). The effect of various cations and anions on Pd(II) and Ni(II) determination have been investigated. The stability constants Pd(II) and Ni(II) were 0.37×108, 0.38×108L mol-1respectively. The conductivity measurements for complexes are consistent with those expected for an electrolyte. The optimum conditions for full color development for described methods were applied satisfactorily to synthetic mixtures samples and biological samples.

Studies on the removal of two dyes (sulphanilic azo antipyrine and sulphanilic azo imidazole) from aqueous solution by adsorption on charcoal as an adsorbent were carried out. A series of experiments were under taken in a batch adsorption technique to access the effect of the process variables i.e. contact time, initial dye concentration, initial pH, adsorbent dose and temperature. Adsorbent dosage (0.1 g) higher value for both dyes. The equilibrium in the solution was observed within (35 min) of two sulphanilic dyes on charcoal. The equilibrium isotherms for both dyes were determined to describe the adsorption process. The results showed that the equilibrium data was fitted by of the Freundlich isotherms on charcoal surface. The result obtained shows that the adsorption isotherm for both dyes on charcoal was according to Giles classification. The thermodynamic factors such as ∆Η, ∆G and ∆S were calculated.

This study describes the use of novel azodyes reagents, H 4 L,1- [(1,3,7,4, chromene-5,10-dione, that prepare ellagic acid as a coupling agent with 4-aminoantipyrine, as sensitive and selective analytical reagent for the determination of palladium (II),nickel (II) and silver (I) Ions spectrophotometrically. HL reacts with ions at pH (3,8 and 6) respectively to form colored complexes of 1:2 stoichiometry of Pd(II), Ni(II) and 1:1 for Ag(I) which show a maximum absorbance of 504, 495 and 492nm of molar ratio absorbitivity 3.565x10 3 , 1.966x10 3 and 4.735x10 3 L.mol -1 cm -1 respectively. Fixed optimum conditions were constructed, precision, accuracy, R.S.D.andcorrelation factors. The Beers law was obeyed 0.1-3ppm. The thermal measurements were also studied, all the complexes show three-stage mass loss in their TG/HDSC curves.
