p. 1
Oki Nugraha Putra, Yulistiani Yulistiani, Soedarsono Soedarsono, Susi Subay
DOI
:10.4103/ijmy.ijmy_217_22
Background:
Drug-resistant tuberculosis (DR-TB) is a public health concern that is difficult to treat, requiring long and complex treatment with highly effective drugs. Bedaquiline and/or delamanid have already shown promising outcomes in patients with DR-TB, increasing the rate of culture conversion and lowering TB-related mortality.
Methods:
We comprehensively searched and evaluated the effectiveness of individual regimens containing bedaquiline and delamanid on culture conversion and treatment success. We assessed for quality either observational or experimental studies.
Results:
We identified 14 studies that met the inclusion criteria using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses flowchart with 12 observational and 2 experimental studies. Of 1691 DR-TB patients enrolled in the included studies, 1407 of them concomitantly received regimens containing bedaquiline and delamanid. Overall multidrug resistant (MDR), preextensively drug resistant (XDR), and XDR-TB were seen in 21.4%, 44.1%, and 34.5%, respectively. Of 14 studies, 8 of them reported favorable outcomes including sputum culture conversion and cure rate at the end of treatment, meanwhile 6 studies only reported sputum culture conversion. Sputum culture conversion at the end of the 6
th
month was 63.6%–94.7% for observational studies, and 87.6%–95.0% for experimental studies. The favorable outcome at the end of treatment was 67.5%–91.4%. With high pre-XDR and XDR cases among DR-TB patients with limited treatment options, regimens containing bedaquiline and delamanid provide successful treatment.
Conclusion:
In DR-TB patients receiving regimens containing bedaquiline and delamanid, favorable outcomes were high including sputum conversion and cure rate.

Influence of genetic variability in toll-like receptors (TLR 2, TLR 4, and TLR 9) on human immunodeficiency virus-1 disease progression
p. 10
Gaurav Kaushik, Richa Vashishtha
DOI
:10.4103/ijmy.ijmy_190_22
Background:
It has been demonstrated that toll-like receptors (TLR2), TLR4, and TLR9 which were initially known for recognizing bacterial products are involved in the detection of viral components. It was planned to undertake a prospective longitudinal study among ethnically homogeneous antiretroviral treatment and antitubercular treatment naïve human immunodeficiency virus (HIV)-positive patients representing the north Indian population. The aim of the study was to investigate the influence of TLR2, TLR4, and TLR9 polymorphism in HIV disease progression.
Methods:
The present study was designed to investigate genetic polymorphism in TLRs (TLR2, TLR4, and TLR9) among HIV-infected patients with and without TB coinfection. The study population consisted of two groups: (i) HIV-positive patients without TB infection and disease (
n
= 223, HIV-positive patients); (ii) HIV-positive patients with latent tuberculosis infection (LTBI) (
n
= 150, HIV-positive LTBI patients). These participants were of either gender between 18 and 60 years of age and treatment naïve for both TB and HIV. HIV-positive and HIV-positive LTBI patients were longitudinally followed up for t2 years to study HIV disease progression.
Results:
On comparing TLR2 and TLR4 allelic and genotypic frequencies between 306 HIV-positive patients (no TB/AIDS) and 47 HIV-positive patients progressed to active TB/AIDS, no significant difference was observed between the two groups. The frequency of “A” allele in TLR9 was found to be significantly increased in 47 HIV-positive patients who progressed to active TB/AIDS (61.7%) as compared to 42.16% in 306 HIV-positive patients (no TB/AIDS), (
P
< 0.001). Furthermore, a significantly increased frequency of “AA” genotype in TLR9 was observed in 47 HIV-positive patients progressed to active TB/AIDS (55.32%) as compared to 20.26% in HIV-positive patients (no TB/AIDS).
Conclusion:
Findings of the present study revealed that genetic variability in TLR9 may influence HIV disease progression. The AA genotype in TLR9 may be associated with progression to TB/AIDS for 2 years in HIV-positive patients.

Evaluation of possibility of cultivation of acid resistant bacteria on solid egg-based and agar cultural media
p. 17
Artem Lyamin, Alena Ereshchenko, Vladimir Antipov, Andrey Kozlov, Danir Ismatullin, Tatyana Nikitina
DOI
:10.4103/ijmy.ijmy_221_22
Background:
The increase in the number of patients at risk for opportunistic infections caused by rare bacteria, which include individual representatives of acid-resistant bacteria (ARB), is a serious problem in modern health care. Significant difficulties in the etiological diagnosis of mycobacteriosis, nocardiosis, and actinomycosis are associated not only with the problem of identifying the main pathogens but also with certain difficulties in isolating pathogens from biological material.
Methods:
The research provides data on 402 strains of ARB, which were isolated from various biological materials obtained from patients during examination for tuberculosis. All samples of biological material were negative on the
Mycobacterium tuberculosis
complex. The isolates were identified on the MALDI-ToF mass spectrometer. The cultural characteristics of ARB were evaluated on the solid Löwenstein–Jensen egg-based culture media, universal chromogenic media, and 5% blood agar with lamb blood.
Results:
The studies carried out indicate the possibility of culturing ARB representatives on agar media. At the same time, based on the comparison of the growth properties of ARB, it was found that the universal chromogenic media provides more acceptable conditions for the isolation of nontuberculous mycobacteria (NTM) compared to blood agar. The comparison of the growth rate of bacteria did not reveal significant differences for fastly growing NTM. For slowly growing species, the growth rate on blood agar was lower than on chromogenic media and on the Löwenstein–Jensen media.
Conclusion:
Thus, the use of a universal chromogenic media during incubation makes it possible to isolate and preidentify representatives of the ARB under the conditions of standard operating procedures of the microbiological laboratory.

p. 23
Mohammadreza Salehi, Reza Shahsiah, Kiarash Mohammad Khorasani, Malihe Hasannezhad, Arian Rahimi, Bahare Yousefi, Amir Aliramezani
DOI
:10.4103/ijmy.ijmy_210_22
Background:
Tuberculosis (TB) is one of the most serious public health problems worldwide which is a chronic infectious disease and is still one of the major challenges for developing countries. This study was undertaken to identify
Mycobacterium TB
(MTB) in clinical specimens in hospitalized patients.
Methods:
The study was carried out on specimens from pulmonary and extrapulmonary suspected TB patients that were admitted to one of the largest tertiary hospitals located in Tehran, Iran from 2017 to 2021. The GeneXpert MTB/rifampin (RIF) method was applied to detect MTB and RIF resistance. Characteristics of demography, clinical features, and lifestyle were obtained from medical case records registered in the hospital.
Results:
Of 957 specimens, 92 (9.61%) were found positive for TB by GeneXpert assay. Of positive samples, 72 (78.26%) were considered pulmonary TB, and 20 (21.73%) of them are associated with extrapulmonary involvement. Four (4.3%) positive TB cases were categorized as rifampicin-resistant.
Conclusion:
This study showed a relatively high incidence rate of TB in distinct types of specimens in Iranian hospitalized patients but a low level of RIF resistance.

p. 28
Vivek Kumar Kori, Deepanshu Bandil, Mohit Asthana, Deepak Singh Maravi
DOI
:10.4103/ijmy.ijmy_233_22
Background:
Osteoarticular tuberculosis (OATB) is a form of extrapulmonary tuberculosis (TB) affecting bones and joints. There is a paucity of data on skeletal TB epidemiology in the annual TB reports and current literature. Many atypical presentations of the disease have also emerged. This necessitates periodic observation of the epidemiological profile of OATB. The aim of this study is to analyze the prevailing epidemiological trends of OATB in Central India.
Methods:
The 5-year ambispective observational study was conducted at the department of orthopedics of a tertiary care center in Central India. Records of patients diagnosed with OATB from January 2017 to December 2021 were analyzed for demographic factors, site of lesion, comorbidities (pulmonary TB, human immunodeficiency virus, and diabetes), etc., Chi-square test for linear trend was used to determine whether a linear trend exists in the number of diagnosed cases.
Results:
Two hundred and ten skeletal TB lesions were found in 208 patients included in the study. OATB was highly reported in young adults and females. Spinal lesions were three times more common than extraspinal OATB lesions. The lumbar spine was the most affected region. Hip was the most common extraspinal site. Unusual sites such as sternoclavicular joint and ischial tuberosity were also involved.
Conclusion:
The burden of OATB is increasing, especially spinal TB. The involvement of atypical sites insists on strong clinical suspicion for early diagnosis. The practice of empirical antitubercular chemotherapy needs to be reviewed considering the risk of drug resistance.

Association between severity of COVID-19, Periodontal health and disease in Riyadh subpopulation
p. 33
Pradeep Koppolu, Esraa Mohamed Genady, Lelian Mohammed Albdeirat, Farah Amer Sebai, Dalal Mohamemd Alrashdi, Amara Swapna Lingam, Fatima Abdulmohsin R. Alsada, Fatimah Ibrahim Al-Khalifa, Rawa Kamal Abdelrahim
DOI
:10.4103/ijmy.ijmy_236_22
Background:
Periodontitis and coronavirus disease (COVID-19) both exhibit an exaggerated inflammatory response as common traits. Given that periodontal diseases have been linked to respiratory illnesses like pneumonia, it is quite possible that periodontitis and COVID-19 are related. Therefore, the purpose of the current study was to ascertain whether the severity of COVID-19 and periodontal disease are related.
Methods:
A retrospective study was done using the 3 years of patients' medical and dental records in the University Hospital. A telephone interview was employed to estimate the severity of symptoms got through COVID-19 infection. The data obtained were subjected to statistical analysis. The Chi-square test, with statistical significance set at 0.05, was used to determine the relationship between the severity of periodontal disease and the severity of COVID-19.
Results:
It was seen that there was a strong relationship between the severities of COVID-19 disease and periodontal disease. The mildest gingivitis cases (63%), Stage 1 periodontitis (62.9%), were associated with the COVID-19-negative group, whereas the most severe gingivitis cases (85.7%), Stage 4 periodontitis group (66.66%), were associated with COVID-19-positive group. In comparison to those without periodontitis, patients with periodontitis had a 1.54 times higher risk of COVID-19 complications (
P
= 0.048). Patients who had comorbidities were 2.49 times to have COVID-19 complications (
P
= 0.02).
Conclusion:
The observations presented above lead to the conclusion that COVID-19 and periodontal disease severities are related. Understanding the potential association between periodontitis and COVID-19 through systemic inflammation could be a means of achieving a high-quality medical care. To validate the findings, additional research with larger samples is required.

Tuberculosis in elderly population: A cross-sectional comparative study
p. 38
Varatharajan Sakthivadivel, Archana Gaur, Jeganathan Geetha
DOI
:10.4103/ijmy.ijmy_235_22
Background:
Tuberculosis (TB) is a common but neglected infectious disease of global significance. It has a varied presentation in the elderly compared to adults. The present study was conceived to study the resemblances and differences shared in terms of clinical profile, comorbidities, and laboratory investigations by TB in adults and the elderly population.
Methods:
In this cross-sectional study, 68 adults and 72 elderly patients of both genders were enrolled. We collected information on demographics, comorbidities, clinical presentations, and laboratory investigations. The comparison of data between groups was done using the unpaired
t
-test for continuous variables and the Chi-square test for frequency distribution analysis.
Results:
The mean age of the adults and elderly population was 42.13 ± 10.7 years and 68.78 ± 7.62 years, respectively. The elderly TB group demonstrated loss of weight, appetite, the prevalence of comorbid conditions (coronary artery disease, hypertension, and malnutrition), bilateral, predominantly lower lobe, and diffuse involvement of lungs.
Conclusion:
As the elderly population increases, nonspecific clinical manifestations or laboratory results in this population mandate awareness of these atypical features for effective management of TB in this group.

Epidemiology of the koch phenomenon of infants after bacillus calmette–Guerin vaccination by interferon-γ release assay status, Japan, 2013–2019
p. 43
Masaki Ota, Yoshiyuki Furuichi, Susumu Hirao
DOI
:10.4103/ijmy.ijmy_203_22
Background:
The epidemiology of infants who exhibited the Koch-like phenomenon after Bacillus Calmette–Guérin vaccination and who subsequently tested positive in interferon-γ release assay (IGRA) was compared to that of those who tested negative. The reports of pediatricians on the phenomenon to the health authorities of Japan were retrieved and analyzed.
Methods:
In 2013–2019, 790 infants with such events were reported with IGRA test results available, of whom 81 (10.3%) tested positive and 709 (89.7%) negative.
Results:
The infants who were IGRA positive did not show an increasing trend (
P
= 0.06,
P
= 0.60), whereas those who were IGRA negative showed a significantly increasing trend (
P
= 0.42,
P
= 0.0002). The infants who were IGRA positive did not exhibit seasonality, whereas those who were IGRA negative had a higher number of cases in winter than in summer. The rates of infants who were IGRA positive per 10 million live births showed a significant correlation with the tuberculosis (TB) notification rates by prefecture (
P
= 0.41,
P
= 0.004), whereas those who were IGRA negative did not (
P
= 0.04,
P
= 0.78).
Conclusion:
The IGRA-positive infants were distributed quite differently from those who were IGRA negative and appeared more likely to be infected with TB. Reports of pediatricians on the Koch-like phenomenon should continuously be collected as the reports reflect a risk of TB infection including TB outbreaks among infants in Japan. The reports should include IGRA test results as IGRA is more specific than tuberculin skin testing. Infants with IGRA-positive results should be followed up for 2–3 years to determine their final outcomes.

Application of chromogenic media for preliminary identification of acid-resistant bacteria
p. 49
Artem Viktorovich Lyamin, Alena Anatolyevna Ereshchenko, Oksana Anatolyevna Gusyakova, Vladimir Alexandrovich Antipov, Andrey Vladimirovich Kozlov, Danir Damirovich Ismatullin
DOI
:10.4103/ijmy.ijmy_6_23
Background:
The variety of morphological and cultural characteristics of acid-resistant bacteria (ARB) makes it possible to use microscopy and estimate the growth rate and pigment formation when cultivating on solid egg media for preliminary identification only as additional indicative methods. It is necessary to develop new approaches for the cultivation and primary identification of ARB isolated from the biological material. It will allow to obtain data on the prevalence, structure, epidemiological, and clinical features of infectious processes caused by opportunistic ARB.
Methods:
Three hundred and sixty strains of ARB were isolated from the various biological materials obtained from the patients during the examination for tuberculosis. All biological material samples were negative on
Mycobacteria tuberculosis
complex. Species identification of all bacteria was performed by matrix-assisted lazer desorption/ion-ization time-of-flight mass spectrometry. The cultural characteristics of ARB were evaluated on a universal chromogenic media. As a selective additive, a mixture of bacitracin and polymyxin sulfate which had no effect on ARB was tested to suppress concomitant Gram-positive and Gram-negative microflora.
Results:
Cultural characteristics were identified and described for all tested representatives of fast-growing nontuberculous mycobacteria (NTM), as well as for all types of nocardia, gordonia, and streptomycetes. Representatives of other genera of ARB on a universal chromogenic media gave meager growth or did not show it at all. When inoculated on a universal chromogenic media with a selective addition, 100% of the strains from the ARB group showed abundant or moderate growth. Incubation time for fast-growing species was up to 7 days; for slow-growing species, it was up to 28 days. Concomitant control strains of Gram-positive and Gram-negative bacteria on universal chromogenic media with selective growth additive did not show the growth.
Conclusions:
The use of a universal chromogenic media allows to preliminarily identify NTM and other ARB by cultural characteristics. The addition of bacitracin and polymyxin sulfate does not reduce the growth properties of ARB, which can be used when working with both biological materials and for the isolation of pure ARB cultures from mixtures with other bacteria.

Nontuberculous mycobacteria isolation from sputum specimens: A retrospective analysis of 1061 cases
p. 55
Aylin Babalik, Emine Nur Koç, Hamide Gül Sekerbey, Gül Erdal Dönmez, Ahmet Balikçi, Zeki Kiliçaslan
DOI
:10.4103/ijmy.ijmy_10_23
Background:
In recent years, with the development of laboratory methods, the frequency of nontuberculosis mycobacteria (NTM) infections has increased. The primary aim of this study was to evaluate the clinical significance of therapeutic drug monitoring (TDM) growths in respiratory samples, and the secondary aim was to evaluate the treatment regimens and treatment outcomes of treatment for TDM disease.
Methods:
This study was a retrospective cohort study. Persons with NTM growth in respiratory samples admitted to the reference hospital between 2009 and 2020 were included in this study. Samples detected as NTM by the immunochromatographic rapid diagnostic test, those requested by the clinicians, species were determined by the hsp65PCRREA method. The subjects were classified into 3 groups: patients with NTM infection who received treatment (135, 12.7%), those followed up without treatment (690, 65.1%), and a last group of patients with
Mycobacterium tuberculosis
(TB) complex strains were isolated and received TB treatment (236, 22.2%). Initiating NTM treatment was decided in accordance with the American Thoracic Society recommendations.
Results:
The mean ± standard deviation age of patients was 53.8 ± 16.5 years, and 749 (70.6%) were male. In total, 278 (26.2%) out of 1061 cases had identified, and the most frequent species were MAC (81;
Mycobacterium avium:
39,
Mycobacterium intracellulare
: 39, and MAC: 3),
Mycobacterium abscessus
(67),
Mycobacterium kansasii
(48),
Mycobacterium fortuitum
(23),
Mycobacterium chelonae
(12),
Mycobacterium gordonae
(11), and
Mycobacterium szulgai
(11). In the NTM treatment group, 116 (85.9%) of 135 patients had multiple culture positivity. Previous TB treatment history had 51 (37.8%) of 135 patients, respiratory comorbidities were evident in 37 (27.4%) of 135 patients. Thorax computed tomography imaging in 84 patients revealed nodule 38 (45.2%), consolidation 46 (54.8%), cavity 52 (61.9%), and bronchiectasis 27 (32.1%). Treatment results in the NTM treatment group were as follows: ongoing treatment 14 (10.4%), cure 64 (47.4%), default 33 (24.4%), exitus 19 (14.1%), recurrence 3 (2.2%), and refractory disease 2 (1.5%).
Conclusion:
This is a large case series evaluating the clinical significance of NTM growths and NTM treatment in Turkey. The clinical significance of NTM growth in respiratory samples is low. Treatment success rates of NTM patients who are treated are low. Treatment defaults and mortality rates are high. New drugs and new regimens are needed.

Transrenal DNA detection of
Mycobacterium tuberculosis
in patients with pulmonary tuberculosis
p. 66
Taeyoon Kim, Jehun Kim, Taeyun Kim, Chul-Ho Oak, Sungweon Ryoo
DOI
:10.4103/ijmy.ijmy_12_23
Background:
Multiple attempts have been made to use biological samples other than sputum to diagnose tuberculosis (TB). Sputum acid-fast bacillus (AFB) microscopy is the fastest, most straightforward, and most inexpensive method for diagnosing pulmonary TB. However, urine can be used in place of sputum owing to its various advantages, such as a noninvasive method of collection, convenient handling and storage, and minimal risk of infection in health-care workers involved in sample collection.
In this study, we aimed to assess the suitability of urine as a sample to obtain transrenal DNA (trDNA) to diagnose TB. This study involved several patients with TB undergoing inpatient treatment, whose AFB microscopy showed negative inversion.
Methods:
Here, 51 urine samples were collected from 40 patients with TB and examined to confirm the presence of trDNA. First, we compared the efficiency of two trDNA extraction methods:
An automated magnetic bead-based method and a more efficient anchoring extraction method. Statistical analyses were performed using Excel software (Microsoft Office Professional Plus 2019).
Results:
Although molecular diagnosis using GeneXpert yielded negative results, a peculiarity was observed. There was no significant difference between GeneXpert findings and our results nor was there any difference in the sequential trDNA samples obtained. However, even when GeneXpert results were negative, trDNA was detected in seven out of ten samples using the anchor extraction method.
Conclusions:
Further studies are needed to establish biomarkers for the progression of TB treatment.

Nutritional status and patterns of anemia in sudanese adult patients with active pulmonary tuberculosis: A cross-sectional study
p. 73
Iman Osman Elfaky, Tarig H Merghani, Izzeldin A Elmubarak, Alaeldin H Ahmed
DOI
:10.4103/ijmy.ijmy_14_23
Background:
Malnutrition increases the risk of developing tuberculosis (TB) and causes reactivation of latent pulmonary TB. On the other hand, TB is a recognized cause of malnutrition. Evaluation of the nutritional status and anemia of tuberculous patients with active disease is an important step toward TB management.
The objectives of the study were to determine the nutritional status and patterns of anemia in adult patients with active pulmonary TB.
Methods:
A
cross-sectional hospital-based study was performed on newly diagnosed patients with sputum-positive pulmonary TB. The nutritional status, total percentage of body fat (BF%), anemia, and general health of each patient were assessed with measurements of the body mass index (BMI), skin fold thickness, complete blood counts, and biochemical tests.
Results:
Patients' ages ranged from 16- to 74-year old, with the majority between 20- and 40-year old. Male: female ratio was 2:1. The majority of males and females (91.2% and 84.5%, respectively) had low BF%. Underweight (BMI < 18.5) was 62%, whereas overweight (BMI ≥25.0) was 4%. BMI showed a significant decline with chronicity of the illness (
P
< 0.001). Eighty participants showed anemia, 90% microcytic hypochromic, and 10% normocytic normochromic. Serum albumin was low in 21%, with no relation to renal disease and insignificant association with proteinuria.
Conclusion:
Patients with active pulmonary TB are likely to have microcytic hypochromic anemia, low BF%, and low BMI, especially with a long duration of the disease.

DOI
:10.4103/ijmy.ijmy_1_23
Background:
The burden of tuberculosis (TB) in Nigeria remains high, and diagnosis in children, a challenge. We aimed to document yield from Xpert
Mycobacterium tuberculosis
/rifampicin (MTB/RIF) as a mode of diagnosis for children and the variables associated with a positive result.
Methods:
This was a retrospective review of TB treatment cards of children aged 0–15 years managed from January 2017 to December 2021 across six public tertiary institutions in Nigeria. The data obtained were analyzed using the descriptive and inferential statistics. Statistical significance was set at
P
< 0.05.
Results:
Of 1489 children commenced on TB treatment, 1463 (97.9%) had sufficient data for analysis the median age of study participants was 60 months (interquartile range [IQR]: 24, 120), and 814 (55.6%) were males. Xpert MTB/RIF test was performed in 862 (59%) participants and MTB was detected in 171 (19.8%) participants, of which 6.4% (11/171) had RIF resistance reported. The use of Xpert MTB/RIF rose from 56.5% in 2017 to 64% in 2020 but fell to 60.9% in 2021. We found that older age (> 10 years), the presence of pulmonary TB (PTB), and a negative human immunodeficiency virus (HIV) status were associated with positive Xpert MTB/RIF tests (
P
= 0.002, 0.001, and 0.012, respectively).
Conclusion:
The utilization of Xpert MTB/RIF in children increased in the years before the COVID-19 pandemic. Factors associated with MTB detection by Xpert MTB/RIF include older age, the presence of PTB, and a negative HIV status. Clinical and radiological evaluation continues to play vital roles in the diagnosis of childhood TB in Nigeria.

Impact and cost-effectiveness evaluation of nutritional supplementation and complementary interventions for tuberculosis treatment outcomes under mukti pay-for-performance model in Madhya Pradesh, India: A study protocol
p. 82
Shankar Prinja, Atul Sharma, Sudheer Nadipally, Saroj Kumar Rana, Pankaj Bahuguna, Neeta Rao, Gautam Chakraborty, Manjunath Shankar, Varsha Rai
DOI
:10.4103/2212-5531.307071
Background:
A
“pay-for-performance” (P4P) intervention model for improved tuberculosis (TB) outcomes, called “Mukti,” has been implemented in an underdeveloped tribal area of central India. The target of this project is to improve nutritional status, quality of life (QoL), and treatment outcomes of 1000 TB patients through four interventions: food baskets, personal counseling, peer-to-peer learning and facilitation for linkage to government schemes. The current study aims to assess the success of this model by evaluating its impact and cost-effectiveness using a quasi-experimental approach.
Methods:
Data for impact assessment have been collected from 1000 intervention and control patients. Study outcomes such as treatment completion, sputum negativity, weight gain, and health-related QoL will be compared between matched samples. Micro costing approach will be used for assessing the cost of routine TB services provision under the national program and the incremental cost of implementing our interventions. A decision and Markov hybrid model will estimate long-term costs and health outcomes associated with the use of study interventions. Measures of health outcomes will be mortality, morbidity, and disability. Cost-effectiveness will be assessed in terms of incremental cost per quality-adjusted life-years gained and cost per unit increase in patient weight in intervention versus control groups.
Results:
The evidence generated from the present study in terms of impact and cost-effectiveness estimates will thus help to identify not only the effectiveness of these interventions but also the optimal mode of financing such measures. Our estimates on scale-up costs for these interventions will also help the state and the national government to consider scale-up of such interventions in the entire state or country.
Discussion:
The study will generate important evidence on the impact of nutritional supplementation and other complementary interventions for TB treatment outcomes delivered through P4P financing models and on the cost of scaling up these to the state and national level in India.

Mucormycosis is called as black fungus, which is caused by fungus belonged to
Mucorales
. If this fungus, effects healthy individuals it won't cause any serious complications, but it may cause life-threatening issues when
Mucorales
affects individuals who have low immunity. The mortality rate of black fungus is more than 50%, and it may also range till 100% if the individual is having any preexisting or chronic disease. This was the case of a 55-year-old male patient complaint of having generalized pain in the maxillary teeth bilaterally and suffering fullness in the maxillary sinus. To check on other possible diseases, doctors have conducted other diagnosis tests, and orthopantomogram revealed in the diagnosis that there was the presence of haziness in the left maxillary sinus, which looked like an incompletely formed soap bubble and additionally he diagnosed with coronavirus disease positive. Then, doctors suggested a chest computerized tomography (CT) along with head CT excluding the brain and further investigation of this case was given below in detail. The report reveals acute necrotizing suppurative sinusitis with dead bony tissue, soft-tissue necrosis with fungal infestation showing broad hyphae with right-angle branching suggestive of mucormycosis.

Tubercular tenosynovitis of the wrist with carpal tunnel syndrome (CTS) is a rare occurrence. The authors present a case of tubercular flexor tenosynovitis of the wrist with CTS. A 60-year-old female presented with complaints of swelling in the volar aspect of the right wrist with numbness of the first three fingers for the past 6 months. Clinical and radiological diagnosis of chronic flexor tenosynovitis with median nerve compression neuropathy was made. The patient was operated with carpal tunnel release and total tenosynovectomy. Histopathology showed features suggestive of Koch's etiology. The patient was started with antitubercular therapy (ATT) and followed up regularly. Carpal tunnel symptoms subsided immediately after surgery and there was no recurrence of swelling at the last follow-up. Carpal tunnel release and tenosynovectomy should be performed at the earliest possible and followed up with ATT for better outcomes in tubercular tenosynovitis of the wrist with CTS.

Cutaneous tuberculosis represents the fifth extrapulmonary form in Morocco after pleural, lymph node, urogenital, and intestinal tuberculosis. It is recognized to form a continuous immunopathologic spectrum, ranging from a high intensity to a low intensity of cell-mediated immunity, which explains the multiplicity and heterogeneity of anatomo-clinical forms. Association of multiple forms in the same patient is really rare. In this regard, we report a case of scrofuloderma on axillary tuberculosis adenitis associated to a lupus vulgaris in an immunocompetent patient, which was confirmed by histology, QuantiFERON-TB Gold test, and polymerase chain reaction. He received an antituberculous therapy with clinical regression of the lesions. In conclusion, cutaneous tuberculosis is still endemic in developing countries.The diagnosis is difficult because of its clinical polymorphism. That's why it's should be suspected clinically in the presence of any destructive or verrucous skin lesion evolving without healing for a long period and confirmed by bacteriological examinations and histology.

A case of spinal tuberculosis presenting with cauda equina syndrome
p. 107

Tuberculosis (TB) of the central nervous system accounts for only 1% of all cases of TB but 50% of these occur in the spine. Common clinical manifestations of spinal TB include fever, weight loss, back pain, lower limb weakness (either upper or lower motor neuron), and skeletal deformities such as kyphosis or gibbus. Infective pathology caused by
Mycobacterium tuberculosis
with epidural collection can present as acute cauda equina syndrome. Here, we describe a 28-year-old female patient who presented with low back pain and ascending weakness of both lower limbs (Medical Research Council grade 4/5 with absent ankle reflex) for 2 months with sudden-onset loss of bladder and bowel control for 1 day without any localized spinal tenderness, swelling, or discharging sinus in the back. Magnetic resonance imaging (MRI) spine was suggestive of an intraosseous collection with spondylodiscitis at the L4 level vertebral level. MRI can help identify the involvement of the vertebral bodies on either side of the disk, disk destruction, cold abscess, vertebral collapse, and the presence of vertebral column deformities making it a sensitive tool for the detection of spinal TB. Antituberculous treatment remains the cornerstone of treatment. Surgery is required in selected cases, for example, large abscess formation, severe kyphosis, an evolving neurological deficit, or lack of response to medical treatment. A combined intervention of laminectomy with drainage of the collection with antitubercular therapy after microbiological evidence helped in the resolution of the patient's condition. Early diagnosis and appropriate treatment generally result in a good prognosis.
