Clinical Observations

The article presents the review of the literature and own clinical observations on the diagnosis and surgical treatment of Mirizzi syndrome – a rare complication of gallstones. The clinical features of the disease has no specific symptoms. The main clinical signs of MS are periodic jaundice (84%), pain in the right hypochondrium (75%) and cholangitis (56%), the phenomenon of acute cholecystitis and pancreatitis. The most informative method of preoperative diagnosis is magnetic resonance imaging, which, unfortunately, not readily available for public use. The diagnostic sensitivity of MRI with MS is 97,6%, intraoperative cholangiography – 94%, ERCP – 86%, PTC – 5%, fibrocholangioscopy – 77%, ultrasound – 46%. The most common type of MS (10,5-51%), less often type II (15-41%), even more rare types III (3-44%), IV (7,4%) and V (2,9% ). The leading role in the treatment of syndrome belongs to open surgery. Laparoscopic cholecystectomy can only be shown to individual MS and type I patients. Conversion with this occurs in 31-100%, complications – 60%, damage to common bile duct – 22%. Open cholecystectomy remains the standard. For Type II and III types of MS, they perform cholecystectomy while retaining part of the Hartmann pocket with the subsequent plastics of CBD at the Kehr drainage. At type IV of the MS it is shown a hepaticojejunostomy. Reorder phases of operation including cholangiography before cholecystectomy made it possible to diagnose and set the type of Mirizzi syndrome, to determine the optimal surgery approach and to prevent intra– and postoperative complications.

The purpose of the study is to improve the results of preoperative diagnosis and treatment of patients with Mirizzi syndrome. The work is based on the analysis of the case histories and clinical observations of 85 patients with chronic obstructive pulmonary disease with a complicated Mirizzi syndrome in the Surgery Clinic No. 2 ONMEDU from 2006 to 2018. There were 63 women (74%) and 22 men (26%). The age of patients ranged from 24 to 97 years. Among the patients studied elderly patients prevailed — 50 (69.3%) and senile age — 28 (3%). All patients 85 (100%) went to the hospital at different stages of development of calculous cholecystitis. In 53 (62%) patients, an acute attack of the disease was noted for the first time. Periodically repeated episodes were noted more often in patients in 32 (38%) patients. The clinical picture of the disease consisted of symptoms characteristic of acute and chronic cholecystitis with the development of mechanical jaundice. The most characteristic and frequently occurring symptoms were dull pain in the upper right quadrant of the abdomen — 58 (68.2%), jaundice and symptoms of cholangitis (chills, fever) — 42 (49.4%). In 41 (48.2%) patients type I CS was diagnosed, in — 29 (34.1%) type II, in 8 (9.4%) — type III, in — 7 (8.2%) patients with type IV CS. In type I, the choice method was laparoscopic cholecystectomy (LCE) in 36 (42.3%), LCE with drainage of choledochus in 10 (11.7%) patients. There were no iatrogenic bile duct lesions and no conversion in this group. The leading role in the treatment of patients with CS was given to open surgical interventions in 39 (45.8%). In type II, the main types of surgical intervention were: "open" cholecystectomy with plastic of the common bile duct on the Kehr's T-tube (in the presence of a defect of not more than 1/3 of the bile duct circumference) in 25 (29.4%); hepaticojejunostomy (in the presence of a defect of more than 1/3 of the circumference of the bile duct) in 14 (16.4%) patients. The main surgical operations with CS III-IV types do not differ in principle from the above operations. So, the use of highly sensitive diagnostic methods and a combination of endoscopic and surgical treatment can significantly improve the results of treatment of patients with Mirizzi syndrome.

Objective:To assess the presentation and surgical management of Mirrizi syndrome patients who underwent LaparoscopicCholecystectomy. Study Design and Setting:Retrospective Descriptive Study was conducted at Surgical Department Combined MilitaryHospital Rawalpindi and Combined Military Hospital Quetta from 1st Jan 2010 to 20th Jan 2016. Methodology:Patients undergoing laparoscopic cholecystectomy during this period were retrospectively reviewed. Allcases of Mirizzi Syndrome (MS) were identified and data analysed. Results:A total of 5500 patients underwent laparoscopic cholecystectomy during this period. Approximately 26(0.47%)cases were identified to be having MS. Out of these 26 cases only 8 (30%) were males while 18 (70%) were females. Ageranged from 25 to 80 years. Three patients (11%) had an endoscopic retrograde cholangiopancreaticography (ERCP) done.Type-I MS was found in 19 cases (73 %), Type-II in 3 cases (11%), Type-III and Type-IV in 2 cases each (7.69 %).Conversion to open surgery was carried out in 15 cases (57.6 %). All type-I MS had cholecystectomy except one casewhere partial cholecystectomy was done. T-tube closure of common bile duct was done in all Type-II MS. Similarly T-tube closure was possible in two cases of type-III while one hadRoux-en-Y hepaticojejunostomy. All cases of type-IV MS had Roux-en-Y hepaticojejunostomy. One patient out of 26 (3.8 %) had carcinoma gallbladder. There was no mortality. Conclusion:Type-I MS can be managed with laparoscopic cholecystectomy in selected patients.Type-II and type-III MS may need placement of T-tube while most of type-IV MS are managed with Roux-en-Y hepaticojejunostomy.

Experimental infection of chimpanzees with non-A, non-B hepatitis (NANB) or with delta agent hepatitis results in the appearance of characteristic cytoplasmic alterations in the hepatocytes. These alterations include spongelike inclusions (Type I), attached convoluted membranes (Type II), tubular structures (Type III), and microtubular aggregates (Type IV) (Fig. 1). Type I, II and III structures are, by association, believed to be derived from endoplasmic reticulum and may be morphogenetically related. Type IV structures are generally observed free in the cytoplasm but sometimes in the vicinity of type III structures. It is not known whether these structures are somehow involved in the replication and/or assembly of the putative NANB virus or whether they are simply nonspecific responses to cellular injury. When treated with uranyl acetate, type I, II and III structures stain intensely as if they might contain nucleic acids. If these structures do correspond to intermediates in the replication of a virus, one might expect them to contain DNA or RNA and the present study was undertaken to explore this possibility.

Abstract The filter-feeding organ of some extinct brachiopods is supported by a skeletal apparatus called the brachidium. Although relatively well studied in Atrypida and Athyridida, the brachidial morphology is usually neglected in Spiriferida. To investigate the variations of brachidial morphology in Spiriferida, 65 species belonging to eight superfamilies were analyzed. Based on the presence/absence of the jugal processes and normal/modified primary lamellae of the spiralia, four types of brachidium are recognized. Type-I (with jugal processes) and Type-II (without jugal processes), both having normal primary lamellae, could give rise to each other by losing/re-evolving the jugal processes. Type-III, without jugal processes, originated from Type-II through evolution of the modified lateral-convex primary lamellae, and it subsequently gave rise to Type-IV by evolving the modified medial-convex primary lamellae. The evolution of brachidia within individual evolutionary lineages must be clarified because two or more types can be present within a single family. Type-III and Type-IV are closely associated with the prolongation of the crura, representing innovative modifications of the feeding apparatus in response to possible shift in the position of the mouth towards the anterior, allowing for more efficient feeding on particles entering the mantle cavity from the anterior gape. Meanwhile, the modified primary lamellae adjusted/regulated the feeding currents. The absence of spires in some taxa with Type-IV brachidium might suggest that they developed a similar lophophore to that in some extant brachiopods, which can extend out of the shell.

Excitatory Responses

1. The electrophysiological responses of single units in the dorsal cochlear nucleus of unanesthetized decerebrate Mongolian gerbil (Meriones unguiculatus) were recorded. Units were classified according to the response map scheme of Evans and Nelson as modified by Young and Brownell, Young and Voigt, and Shofner and Young. Type II units have a V-shaped excitatory response map similar to typical auditory nerve tuning curves but little or no spontaneous activity (SpAc < 2.5 spikes/s) and little or no response to noise. Type I/III units also have a V-shaped excitatory map and SpAc < 2.5 spikes/s, but have an excitatory response to noise. Type III units have a V-shaped excitatory map with inhibitory sidebands, SpAc > 2.5 spikes/s, and an excitatory response to noise. Type IV-T units typically also have a V-shaped excitatory map with inhibitory sidebands, but have a highly nonmonotonic rate versus level response to best frequency (BF) tones like type IV units, SpAc > 2.5 spikes/s, and an excitatory response to noise. Type IV units have a predominantly inhibitory response map above an island of excitation of BF, SpAc > 2.5 spikes/s, and an excitatory response to noise. We present results for 133 units recorded with glass micropipette electrodes. The purpose of this study was to establish a normative response map data base in this species for ongoing structure/function and correlation studies. 2. The major types of units (type II, type I/III, type III, type IV-T, and type IV) found in decerebrate cat are found in decerebrate gerbil. However, the percentage of type II (7.5%) and type IV (11.3%) units encountered are smaller and the percentage of type III (62.4%) units is larger in decerebrate gerbil than in decerebrate cat. In comparison, Shofner and Young found 18.5% type II units, 30.6% type IV units, and 23.1% type III units using metal electrodes. 3. Two new unit subtypes are described in gerbil: type III-i and type IV-i units. Type III-i units are similar to type III units except that type III-i units are inhibited by low levels of noise and excited by high levels of noise whereas type III units have strictly excitatory responses to noise. Type IV-i units are similar to type IV units except that type IV-i units are excited by low levels of noise and become inhibited by high levels of noise whereas type IV units have strictly excitatory responses to noise. Type III-i units are approximately 30% of the type III population and type IV-i units are approximately 50% of the type IV population. 4. On the basis of the paucity of classic type II units and the reciprocal responses to broadband noise of type III-i and type IV-i units, we postulate that some gerbil type III-i units are the same cell type and have similar synaptic connections as cat type II units. 5. Type II and type I/III units are distinguished from one another on the basis of both their relative noise response, rho, and the normalized slope of the BF tone rate versus level functions beyond the first maximum. Previously, type II units were defined to be those nonspontaneously active units with rho values < 0.3 where rho is defined as the ratio of the maximum noise response minus spontaneous rate to the maximum BF tone response minus spontaneous rate. In the gerbil, the average rho value for type II units is 0.25, although a few values are > 0.3, and the rate-level curves are consistently nonmonotonic with normalized slopes steeper than than -0.007/dB. The average rho value for type I/III units is 0.54, although a few values are < 0.3, and the rate-level curves tend to saturate with slopes shallower than -0.006/dB. In general, the response properties of type II units recorded in gerbil are similar to those recorded in decerebrate cat. 6. In comparison to decerebrate cat, the lower percentage of type IV units recorded in decerebrate gerbil may be due to a species difference (a reduced number of type II units in gerbil) or an electrode bias.

Purpose: to study the structure of the swelling lens, the dependence of its anatomical parameters on the nucleus sizes and density, patients’ age.Patients and methods. 52 patients with intumescent mature cataract were examined. All patients underwent phacoemulsification with a two-stage continuous circular capsulorhexis. After the 2–2.5 mm capsulorhexis had been created, the liquid lenticular masses were removed from the anterior and posterior lens compartment with the aspiration/irrigation system. Visually we determined the size of the nucleus, its color and density according to Buratto’s classification.Results. When performing this work 4 types of the swelling lens structure were revealed. Type I — a small emerging white nucleus with large amount of liquid lenticular masses in the anterior and posterior lens compartment, II degree of density according to Buratto’s classification. The mean age was 49.09 ± 3.19 years old. The related ophthalmic diseases accounted for 36.4%. Type II — a large white nucleus with the presence of liquefied lenticular masses in the anterior and posterior lens compartment. III degree of density according to Buratto’s classification. The mean age was 71.00 ± 1.92 years old. Associated diseases — 84.6%. Type III — a large brown nucleus with the presence of liquefied lenticular masses in the anterior and posterior lens compartment. IV degree of density according to Buratto’s classification. The mean age was 75.84 ± 1.46 years old. Associated diseases — 100%. Type IV — a small, very dense, brown nucleus with liquid lenticular masses. V degree of density according to Buratto’s classification. The mean age was 77.33 ± 2.49 years old. Associated diseases — 100%.Conclusion. 4 types of lens structure in intumescent cataract were described depending on the nucleus size, density, the amount of the lenticular masses. By means of UBM method, it was shown that intumescent cataract is accompanied with the alterations of the ocular anterior segment parameters, which depend on the type of lens structure. It was revealed that the types of swelling lens structure are directly connected to the patients’ age: mean age of patients with type I — 49.09 ± 3.19 years old, with type II — 71.00 ± 1.92, with type III — 75.84 ± 1.46, with type IV — 77.33 ± 2.49 years old.

Background: ABO discrepancies occur whenever the results of red cell grouping and serum grouping are in disagreement. The reasons for discrepancies both clinical and technical have to be sorted out. Further analysis is essential to resolve such discrepancies. If discrepancies are encountered, the interpretation of the ABO grouping has to be delayed until the same has been resolved. The aim of the study was to resolve ABO discrepancies encountered, by serological work up.Methods: All cases of discrepant samples received between August 2014 and May 2016 at the Department of Transfusion Medicine, The Tamilnadu Dr. MGR Medical University, Chennai, India were analyzed to determine the etiology by serological workup.Results: A total of twenty-one samples were analyzed and resolved. Fifteen cases of Type IV discrepancy, two cases of Type II discrepancy, one case Type III discrepancy, one case Type I discrepancy and two cases of technical errors were identified.Conclusions: ABO discrepancies can be resolved serologically if properly worked up. As ABO blood grouping is indispensible in blood transfusion service, it is imperative to resolve such discrepancies before transfusion.

Abstract Objective The aim of the present study is to investigate the relationship between pulmonary hamartomas (PHs) and bronchi on multislice spiral computed tomography (MSCT) images. Methods The MSCT scans of 218 PHs from 216 pathologically confirmed patients were reviewed. The PHs were divided into two groups, namely, the central endobronchial and intraparenchymal groups, in accordance with location. Multiplanar reconstruction was used to demonstrate PH–bronchus relationship patterns. The PH–bronchus relationships in the intraparenchymal group were classified into five patterns: type I, the bronchus was cut off by the tumor; type II, the bronchus was contained within the tumor (air bronchogram sign); type III, the bronchus ran at the tumor periphery or was compressed by the tumor; and type IV, no tumor–bronchus relationship was observed. Results Nine (4.1%) PHs were assigned to the central endobronchial group and 209 (95.9%) PHs were assigned to the intraparenchymal group. In the endobronchial group, 1 (11.1%) PH was located in the trachea with the partial stenosis of the trachea, whereas the remaining 8 (88.9%) PHs were located in the lobar or segmental bronchus with the complete occlusion of the corresponding bronchus. In the intraparenchymal group, type IV (147, 70.3%) was most common pattern, followed by type III (54, 25.8%). Type I (8, 3.8%) was rare, and type II was not observed. Conclusion Central endobronchial PHs often obstructed bronchi, whereas only a few intraparenchymal PHs cut off bronchi. No air bronchogram sign was observed.

PURPOSE: To investigate the sub-types of lumbar disc herniation, compare efficacies of ozone treatment in various types of lumbar disc herniation and analyze the mechanisms. MATERIAL AND METHODS: A total of 250 patients (159 males, 91 females; age range: 14 - 85 years) diagnosed of lumbar disc herniation from January 2009 to Jun 2014 in Nanfang Hospital were enrolled. Disc Lesions, classified by Magnetic Resonance examinations and images when injecting ozone under Digital Subtraction Angiography, were divided into four types: type I: Non-prominent nucleus pulposus with ruptured fibre ring; type II: Prominent nucleus pulposus with ruptured fibre ring; type III: Non-prominent nucleus pulposus with Non-ruptured fibre ring; type IV: Prominent nucleus pulposus with Non-ruptured fibre ring. All patients underwent intradiscal and paravertebral injection of oxygen-ozone. Visual Analogue Scale (VAS) weighted score was administered for the measurement of low back pain before treatment, and the evaluation of efficacy respectively at 1 week, 1 month, 6 month and 12 month follow-up period. RESULTS: Most of the patients (about 4/5) showed better response to ozone treatment. Herniated disc shrinkage was obtained among type II and IV. The type II had the most reduction of average score while the type III had the least. The proportion of patients who had once experienced pain relief at the follow up interval, namely the curative efficacy, showed significant difference: type I occupied the most, type IV occupied the least. CONCLUSION: Ozone treatment is effective and safe for all types of lumbar disc herniation, but efficacy varies according the types, of which type I has the best results and type IV has the worst ones.
